The present disclosure claims priority of Chinese Patent Application No. 202420070955.3 filed on Jan. 11, 2024, the entire contents of which are hereby incorporated by reference in their entirety.
The present disclosure relates to the technical field of sticker dispensing, and more specifically to a manual sticker dispenser.
Stickers are sheets that can be attached to other items. The sticker can be printed with barcodes, QR codes, or various symbols or patterns, to be used for information recording, labeling, or entertainment. Commonly, a commercially available sticker is peelably attached onto a liner paper, and a user can manually bend the liner paper such that an edge of the sticker opens up a small opening from the liner paper, whereby the sticker can be removed. This conventional method of peeling off the sticker is inconvenient, in which the liner paper may be wrinkle, and the sticker or liner paper may be torn.
Based on this, the Applicant has developed a sticker dispenser, such as published Chinese patents No. CN219970240U and CN219750321U, which realizes automatic peeling off of stickers by driving a sticker roll to rotate by means of a motor and changing conveying directions of the liner paper and the sticker at a position close to an output port. These technical solutions proposed by the Applicant overcome the above problems existing in the related art. However, the above technical solutions are adopted with a motor to drive the sticker roll to rotate, requiring the use of electrical components such as motor, circuit board, battery, etc., which is costly and requires charging or replacing the battery after a long-term use.
In view of this, the Applicant further develops and proposes a novel technical solution of a sticker dispenser.
The present disclosure provides a manual sticker dispenser, such that the output of stickers may be realized by manually operations, without using electrical components, thereby reducing costs and enhancing operability and entertainment.
In order to achieve the above objectives, the technical solutions adopted in the present disclosure are as follows.

A gear shaft of the actuating gear 3 is non-translatably connected to the housing 1, and the actuating gear 3 is only capable of rotating about the axis of its gear shaft and is not movable in its axial and radial directions. In the embodiments, the actuating gear 3 is a double-layered tower gear having a small-diameter toothed disk 31 and a large-diameter toothed disk 32 that are arranged coaxial, the small-diameter toothed disk 31 of the actuating gear 3 being engaged with the rack portion 22 of the operating member 2, and the large-diameter toothed disk 32 of the actuating gear 3 being engaged with the movable gear 4. In other embodiments, the large-diameter toothed disk 32 may be understood as an actuating gear, and the small-diameter toothed disk 31 as a first gear further included in the transmission mechanism and coupled to the rack portion 2, the first gear and the actuating gear being coaxially disposed. The diameter D of the actuating gear is greater than double the diameter d of the first gear.
The movable gear 4 is configured to be movable between a coupled position and a detached position, i.e. a gear shaft of the movable gear 4 is translationally connected to the housing 1, while the movable gear 4 is also rotatable about an axis of its gear shaft. An end of the gear shaft of the movable gear 4 is connected to a bottom wall of the main body shell 11 and the other end of the gear shaft of the movable gear 4 is connected to the lower cover 13. Specifically, the bottom wall of the main body shell 11 defines an upper elongate slot 113 configured for an upper end of the gear shaft of the movable gear 4 to be inserted and slide therein; the lower cover 13 defines a lower elongate slot 131 configured for a lower end of the gear shaft of the movable gear 4 to be inserted and slide therein. The upper elongate slot 113 and the lower elongate slot 131 are opposite each other in the top-bottom direction, forming guide slots for the rotation shaft of the movable gear 4 to be inserted into and to slide within. When the rack portion 22 of the operating member 2 is engaged with the movable gear 4, the movable gear 4 can be pushed to slide along the guiding slot 131. When the movable gear 4 slides to the coupled position, it can engage with the driven gear 5. When the movable gear 4 slides to the detached position, it can disengage with the driven gear 5.
In the embodiments, the one-way clutching device includes the movable gear 4 and a force-applying member 6. The movable gear 4 is resiliently pushed against by the force-applying member 6, and the force-applying member 6 is configured to apply a resilient force to hold the movable gear 4 in the coupled position. When the operating member 2 moves in the second direction from the second position to the first position, the operating member 2 drives the movable gear 4 to overcome the resilient force and to slip to the detached position. The force-applying member 6 may be a torsion spring or a resilient sheet, with a resilient arm that abuts against the movable gear 4 to exert the resilient force. In the embodiments, the force-applying member 6 is a torsion spring having two resilient arms, one of which abuts against the movable gear 4 and the other abuts against the housing 1. In the embodiments, the spring force of the force-applying member 6 is overcome to separate the movable gear 4 from the driven gear 5. In other embodiments, the force-applying member 6 is configured to apply a resilient force for the movable gear 4 to remain in the detached position, and the operating member 2 drives the movable gear 4 to overcome the resilient force to slide to the coupled position when the operating member 2 moves in the first direction from the first position to the second position; herein when the operating force is released, the movable gear 4 is separated under the action of the spring force of the force-applying member 6. For the embodiments, the force-applying member 6 instantly drives the movable gear 4 to the detached position from the driven gear 5 when the external force on the operating member 2 is removed, such that the separation is timelier and the driven gear 5 can be better avoided from being driven to rotate in reverse. Further, there exists a small slip distance for the movable gear 4 to move from the detached position to the coupled position during the movement of the operating member 2 in the first direction, and the driven gear 5 is not driven in the slip distance, i.e. there exists a small empty travel distance of the operating member 2. In the embodiments, the reset spring 23 provides a resilient resetting force greater than the resilient force applied to the movable gear 4 by the force-applying member 6.
In the embodiments, the movable gear 4 is a double-layered tower gear having a small-diameter toothed disk 41 and a large-diameter toothed disk 42 that are arranged coaxial, the small-diameter toothed disk 41 of the movable gear 4 being engaged with the actuating gear 5, and the large-diameter toothed disk 42 of the movable gear 4 being engaged with the large-diameter toothed disk 32 of the actuating gear 3. The provision of the actuating gear 3 and movable gear 4 may serve to amplify the fact that the rotation angle of the actuating gear 3 is less than the rotation angle of the driven gear 5 during the movement of the operating member 2 from the first position to the second position.
The driven gear 5 is coaxially and relatively fixedly connected to the winding shaft 111. In the embodiments, the driven gear 5 is connected to the winding shaft 111 by a coupling structure. Specifically, a gear shaft of the driven gear 5 is arranged with a polygonal post, and a lower end of the winding shaft 111 is arranged with a polygonal sleeve, the polygonal post being inserted into the polygonal sleeve to realize a relative fixation of the polygonal post and the polygonal sleeve in a rotation direction.

It should be noted that the present embodiments are illustrated with the movable gear 4 and the driven gear 5 being able to be disengaged as an example, and it can be understood that in other embodiments, it is sufficient to arrange such that a disengagement is feasible at any position in the transmission chain between the operating member 2 and the winding shaft 111. It should also be noted that, in the present embodiments, the switching between engagement and disengagement is achieved by translation of the movable gear 4, which in other embodiments can be achieved by means of a ratchet structure. For example, in some embodiments, the one-way clutching device is a one-way bearing, i.e. an overrunning clutch, which is coupled to a transmission gear within the transmission mechanism; the one-way bearing is free to rotate in one direction independently of the winding shaft 111, while in the other direction opposite, the one-way bearing is locked to the winding shaft 111 and both rotate in synchronization.
As can be seen from the above description of specific embodiments, the present disclosure provides a manual sticker dispenser 100 including a winding shaft 111, a transmission mechanism, and an operating member 2; the operating member 2 is configured to be driven by an operating force to move in a first direction, and is configured to move in a second direction opposite to the first direction when the operating force is released; during a movement of the operating member 2, a continuous power transmission chain is formed between the operating member 2, the transmission mechanism, and the winding shaft 111, to drive the winding shaft 111 to rotate and wind the liner paper; during a movement of the operating member 2 in the second direction, the one-way clutching device disconnects the power transmission, which avoids driving the winding shaft 111 in reverse. Therefore, the output of stickers may be realized by manually applying force on the operating member 2, without using electrical components, thereby reducing costs and enhancing operability and entertainment.
Although the above description has been made herein with reference to specific embodiments, the scope of the present disclosure is not limited thereto. The preceding detailed description is intended to be considered illustrative and not limiting, and it should be understood that the appended claims, including all equivalents, are intended to limit the scope of the present disclosure. The claims should not be construed to be limited to the order or elements described, except as indicated. Accordingly, all embodiments falling within the scope and spirit of the appended claims and their equivalents are claimed to be protected by the present disclosure.
