This application is a National Phase entry of PCT Application No. PCT/CN2015/085187, filed Jul. 27, 2015, which claims the benefit of priority to Chinese patent application No. 201410380586.9, titled “DOUBLE-PAPER-ROLL PRINTING DEVICE”, filed with the Chinese State Intellectual Property Office on Aug. 4, 2014, the entire disclosures of which are incorporated herein by reference.
This application relates to a printing device, and particularly to a double-paper-roll printing device of a self-service equipment, which achieves a free switch between two paper rolls with different types.
In the industries such as rail transportation, finance and banking, papermaking, printing, medical health, electrical power, supermarket, lottery, catering, POS terminal and the like, a paper transaction voucher is required to provide to users. Related transaction information is required to be printed on the paper transaction voucher instantly, therefore, currently, in order to achieve a continuous voucher printing, a roll of paper is generally provided for printing or cutting, and the paper roll may be replaced as desired.
For extending the continuous printing time of a printing device and thus avoiding frequent replacement of the paper roll, a conventional solution is to increase the amount of a paper tape by increasing a diameter of the paper roll, thus, the continuous printing time is extended. Another solution is to increase the number of paper rolls. Although the solution to increase the number of paper rolls may achieve the extension of printing time of printing equipment, the equipment would be more complicated. Further, it is difficult in a certain degree in technique to switch the paper rolls, thus paper is apt to be jammed frequently. Therefore, the technical issue sought to be addressed by those skilled in the art continually is to provide a printing equipment, which takes up space as less as possible, reduces the risk of paper jam and facilitates clearance and maintenance even in the case that paper jam occurs.
To overcome the defects of the conventional printing device, the present application provides an open-type double-paper-roll printing device in which smaller operation space is needed to replace the paper roll.
The double-paper-roll printing device includes an installation frame for installing the following components and paper rolls. A first paper roll and a second paper roll are installed on the installation frame by a first paper roll supporting shaft and a second paper roll supporting shaft. Paper tapes of the first paper roll and the second paper roll are selectively fed to a printing component through paper passages. The first paper roll and the second paper roll are selectively fed to the printing component respectively through a first paper passage and a second paper passage that are mutually independent. The first paper passage and the second paper passage are mutually superposed. A tail end of the first paper passage and a tail end of the second paper passage form an intersecting end, and paper tape heads of the paper rolls enter the printing component by the intersecting end.
Preferably, one common paper passage is provided between the printing component and the intersecting end formed by the tail end of the first paper passage and the tail end of the second paper passage.
Further, a sensor for detecting the paper tapes is provided in the common paper passage.
Preferably, the first paper passage and the second paper passage comprise a first paper passage top assembly, a middle assembly and a second paper passage lower assembly. The middle assembly includes two passage faces, i.e., a first passage face and a second passage face which are respectively adjacent to the first paper passage and the second paper passage. The first paper passage comprises the first passage face and the first paper passage top assembly, and the second paper passage comprises the second passage face and the second paper passage lower assembly.
Preferably, the first paper passage top assembly is pivotally connected to the middle assembly, and the middle assembly is further pivotally connected to the second paper passage lower assembly.
Preferably, a paper cutting assembly for cutting off the paper tape that has been printed is provided outside a paper-exit passage of the printing component.
Further, a paper delivering passage for delivering a paper sheet out is further provided outside the paper cutting assembly of the printing component. The paper delivering passage is pivotally connected to the installation frame by one rotation shaft, and a selective separation of the paper transportation passage from the paper cutting assembly is achieved.
Preferably, the first paper roll and the second paper roll are supported by the first paper roll supporting shaft and the second paper roll supporting shaft fixed to the installation frame. One end of the paper roll supporting shaft is a free end and selectively locked by a movable baffle which is pivotally connected to the installation frame by a baffle rotation shaft.
Further, a tension spring is provided between the movable baffle and the installation frame, and the tension spring has two ends respectively fixed to the movable baffle and the installation frame.
Further, the free end of the paper roll supporting shaft is provided with a position-limiting slot, and the movable baffle is provided with a lock plate having an automatic reset function corresponding to the position-limiting slot.
When compared with the conventional technology, the present application has the following advantageous effects:
1. in the technical solution of the present application, the paper passages for two paper rolls are designed to be mutually independent and the passage assemblies that are formed by the two independent paper passages are mutually superposed and pivotally connected in turn and form open passages, which is beneficial to the clearance of the paper jam in the passages;
2. the installation of a paper roll is achieved by replacing from a side. One end of the paper roll supporting shaft is a free end, so that the paper roll may be replaced from the side. In this way, the maintenance operation space needed by the equipment is reduced as much as possible. Also, the free end is selectively locked by a movable baffle, which not only ensures a safe operation of the equipment but also saves the space taken up the equipment.
For more clearly illustrating embodiments of the present application or the technical solutions in the conventional technology, drawings referred to describe the embodiments or the conventional technology will be briefly described hereinafter. Apparently, the drawings of the present application in the following description are only some examples of the present application, and for the person skilled in the art, other drawings may be obtained based on these drawings without any creative efforts.
To further illustrate the double-paper-roll printing device according to the present application, the preferred embodiments of the present application will be described further in detail hereinafter in conjunction with the drawings thereof.

Referring to
As shown in
For allowing the movable baffle 2 to reliably block the paper roll 6, as shown in
As shown in
For facilitating the opening and closing of the movable baffle 2, a tension spring 12 is provided between the movable baffle 2 and the installation frame 13 in the double-paper-roll printing device according to the present application. Two ends of the tension spring 12 are respectively fixed to the movable baffle 2 and the installation frame 13. Also, when the movable baffle 2 is opened or closed, both of the two fixing points of the tension spring 12 are not in a line with the baffle rotation shaft 11.
Reference is made to
Further, for allowing the paper roll supporting shaft 14 to be stably fixed to the installation frame 13, in the double-paper-roll printing device according to the present application, the paper roll supporting shaft 14 is fixed to the installation frame 13 with the aid of a fixing plate 15 and then is fastened from one end of the paper roll supporting shaft 14 by a bolt 16. For achieving fixing of all the components, as shown in
A paper roll replacement process of the double-paper-roll printing device according to the present application will be further described hereinafter with reference to
The above description is only preferred embodiments of the present application. It should be noted that the above preferred embodiments should not be construed as limiting to the present application. The protection scope of the present application should be defined by the scope defined by the claims.
