1. Field of the Invention
The present invention relates to a roller adjusting device of an optical laser-lens seat, and more particularly to a roller adjusting device of an optical laser-lens seat for increasing the stability and accuracy of rollers on guiding rails. The device is structurally simple, convenient for assembling as well as adjusting. It is suitable for applying to an optical laser-lens seat of a processing equipment of a laser-engraving machine.
2. Description of the Prior Art
Drawing machines, printing machines and laser-engraving machines are similar in having printing heads (engraving heads) mounting on rails, by moving right and left of the printing heads (engraving heads) and moving frontwards and backwards of papers (articles engraved), data (drawings) can be printed (engraved) on the papers (articles engraved).
A conventional laser-engraving machine takes advantage of a lens of an optical laser-lens seat mounted on guiding rails, in order that laser light is projected by lens reflecting. The optical laser-lens seat has rollers in order that the optical laser-lens seat can move to and fro on the guiding rails, so that the laser light is projected by lens reflecting in different angles.
However, referring to
In view of this, a user will change all the spring leaf and the rollers clamped after using a period of time or based on experiences. But the timing for rollers changing is hard to decide because it costs high and generates waste material, more importantly, it also affects the quality and superiority of the machine products.
The primary objective of the present invention is to provide a roller adjusting device of an optical laser-lens seat, the device is structurally simple; it can increase the stability and accuracy of rollers on guiding rails.
To achieve the above objective, the roller adjusting device of the optical laser-lens seat of the present invention is used on a laser-engraving machine for roller adjusting, in order that the rollers can slide stably on the guiding rails. The roller adjusting device includes a sheet member. The sheet member is provided on its two ends each with a notch, each notch is formed at its two lateral sides pressing areas and each of the pressing areas is provided with a tightening means. When the sheet member is horizontally fixed on a spring leaf clamping the rollers, the tightening means are adjusted to press downwardly the spring leaf, the rollers can thus cling more tight to the guiding rails.
The present invention will be apparent in its content of construction and the effect to be achieved after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
Referring firstly to
The roller adjusting device 1 includes a sheet member 11 having locking holes 111 thereon; the sheet member 11 can be fixedly locked on a spring leaf 5 clamping the rollers 3. The sheet member 11 is provided on its two ends each with a notch 112, 113, the notches 112, 113 are formed at their lateral sides pressing areas 114-117 respectively. Each of the pressing areas 114-117 is provided with a tightening means 12. In this embodiment, the tightening means 12 can be a locking member 13 such as a set of screw and nut. The roller adjusting device 1 further includes a pair of separating sheets 14, 15; the separating sheets 14, 15 are provided with holes 141, 151 aligned mutually. The sheet member 11 sandwiched in the separating sheets 14, 15 can be locked fixedly together with the spring leaf 5 clamping the rollers 3.
In practicing, referring to
Therefore, when the rollers 3 on the optical laser-lens seat 2 move to and fro on the guiding rails 4 for a long time to have gaps, a user can adjust the locking members 13 on the pressing areas 114-117 on the two ends of the sheet member 11 to render the locking members 13 to press the roller clamping areas 51-54 on the two ends of the spring leaf 5. Thereby the roller clamping areas 51-54 are forced to bend down, and the rollers 3 clamped by the roller clamping areas 51-54 cling more tight to the guiding rails 4.
Accordingly, the present invention has the following advantages:
In conclusion, according to the specification and drawings disclosed above, the present invention surely can achieve the expected objective thereof to provide a roller adjusting device which is structurally simple, and convenient for assembling as well as adjusting.
The preferred embodiment is only for illustrating the technical measures used for the present invention. It will be apparent to those skilled in this art that various equivalent modifications or changes can be made to the elements of the present invention without departing from the spirit and scope of this invention. Accordingly, all such modifications and changes also fall within the scope of the appended claims and are intended to form part of this invention.
