Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing squeegee technology, and in particular to a squeegee swinging device for printing. Background Technology
[0002] Printing is a technology that uses processes such as plate making, inking, and pressing to transfer ink to the surface of materials such as paper, textiles, and leather to reproduce the content of the original manuscript in batches.
[0003] In reality, printing is done by squeezing ink with a squeegee. However, existing squeegees are difficult to adjust in terms of angle, which affects print quality. Furthermore, during printing, some ink is squeezed to the sides by the squeegee and accumulates. Printing workers need to shovel the accumulated ink back to the printing area in the center of the screen. This continuous shoveling process affects the printing efficiency of the equipment and increases the labor intensity of the printing workers. Utility Model Content
[0004] The purpose of this invention is to provide a oscillating device for printing squeegees, in order to solve the problems mentioned in the background art, such as the difficulty in adjusting the angle of existing squeegees, which affects printing quality and results in high labor intensity for printing workers.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a printing squeegee swinging device, comprising a mounting frame, a mounting seat rotatably provided at the bottom of the mounting frame, a mounting hole provided in the middle of the mounting seat, a squeegee provided in the mounting hole, locking assemblies for locking the squeegee symmetrically provided on the sidewall of the mounting hole, guide plates provided at both ends of the mounting seat, and drive assemblies provided at both ends of the mounting frame.
[0006] Preferably, the locking assembly includes a telescopic cavity provided on the side wall of the mounting hole, a lock head is slidably provided in the telescopic cavity, the bottom wall of the telescopic cavity is connected to the lock head by a spring, the top of the mounting base is provided with a guide groove communicating with the telescopic cavity, and a lever fixedly connected to the lock head on the same side is slidably provided in the guide groove.
[0007] Preferably, the scraper sidewall is provided with a slot for engaging the lock head, and the inner wall of the mounting hole is provided with a plurality of buffer members symmetrically and linearly, with the scraper having a groove corresponding to the buffer members.
[0008] Preferably, the mounting base has a through hole at its end corresponding to the guide plate, and a rotating shaft is provided in the through hole, with one end of the rotating shaft fixedly connected to the guide plate.
[0009] Preferably, the drive assembly includes a gear one provided at the end of the mounting base, a gear two provided at the top of the rotating shaft on the same side, an electric cylinder provided at the top of the mounting bracket, a connecting rod fixedly connected to the telescopic end of the electric cylinder, and a rack connected to one side of the connecting rod that meshes with the gear one and the gear two.
[0010] Preferably, the mounting bracket has several threaded holes on its top.
[0011] The beneficial effects of this utility model are:
[0012] 1. By installing the scraper from the bottom of the mounting base into the mounting hole, the scraper adaptively presses the locking heads on both sides into the slots, thus fixing the scraper on the mounting base. By moving the levers on both sides, the scraper in the mounting hole can be unlocked. When the scraper is worn, it can be quickly replaced by pulling down the scraper.
[0013] 2. By setting several buffer components, the scraper is prevented from falling out of the mounting hole when the lock head unlocks the scraper, thus improving the reliability of the device.
[0014] 3. By controlling the extension and retraction of the electric cylinder, the rack and pinion are driven to mesh synchronously with gear one and gear two, which in turn drives the mounting base and guide plate to rotate synchronously, thereby adjusting the angle of the mounting base and guide plate. When the squeegee is printing to one side, the paste squeezed to both ends by the squeegee is guided back to the screen printing area by the guide plate, preventing the paste from accumulating on both sides of the squeegee, improving printing quality, and reducing the labor intensity of printing workers.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 This utility model provides a printing squeegee swinging device, including a mounting frame 1, a mounting base 2 rotatably provided at the bottom of the mounting frame 1, a mounting hole 3 provided in the middle of the mounting base 2, a squeegee 4 provided in the mounting hole 3, and locking assemblies 5 for locking the squeegee 4 symmetrically provided on the side wall of the mounting hole 3, guide plates 6 provided at both ends of the mounting base 2, and drive assemblies 7 provided at both ends of the mounting frame 1.
[0022] like Figure 3 As shown, specifically, the locking assembly 5 includes a telescopic cavity 51 provided on the side wall of the mounting hole 3. A lock head 52 is slidably provided in the telescopic cavity 51. The bottom wall of the telescopic cavity 51 is connected to the lock head 52 by a spring 53. The top of the mounting base 2 is provided with a guide groove 54 communicating with the telescopic cavity 51. A lever 55 fixedly connected to the lock head 52 on the same side is slidably provided in the guide groove 54. By installing the scraper 4 from the bottom of the mounting base 2 into the mounting hole 3, the scraper 4 adaptively presses the lock heads 52 on both sides and engages with the slots 41, thus fixing the scraper 4 on the mounting base 2. By moving the levers 55 on both sides, the scraper 4 in the mounting hole 3 can be unlocked. When the scraper 4 is worn, the scraper 4 can be quickly replaced by pulling down the scraper 4.
[0023] like Figure 2 and Figure 4 As shown, specifically, the scraper 4 has a slot 41 on its side wall for engaging the lock head 52, and a plurality of buffers 8 are symmetrically arranged on the inner wall of the mounting hole 3. The scraper 4 has a groove 42 corresponding to the buffers 8. By setting a plurality of buffers 8, the scraper 4 is prevented from falling out of the mounting hole 3 when the lock head 52 unlocks the scraper 4, thereby improving the reliability of the device.
[0024] Specifically, the buffer 8 includes, but is not limited to, elastic balls.
[0025] Specifically, the mounting base 2 has a through hole 21 at its end corresponding to the guide plate 6, and a rotating shaft 9 is provided in the through hole 21. One end of the rotating shaft 9 is fixedly connected to the guide plate 6.
[0026] Specifically, the drive assembly 7 includes a gear 71 at the end of the mounting base 2, a gear 72 at the top of the rotating shaft 9 on the same side, an electric cylinder 73 at the top of the mounting frame 1, a connecting rod 74 fixedly connected to the telescopic end of the electric cylinder 73, and a rack 75 connected to one side of the connecting rod 74 to mesh with the gear 71 and the gear 72. By controlling the telescopic extension of the electric cylinder 73, the rack 75 is driven to mesh synchronously with the gear 71 and the gear 72, thereby adjusting the angle of the mounting base 2 and the guide plate 6 and improving the printing quality.
[0027] Specifically, the top of the mounting bracket 1 is provided with several threaded holes 11 to facilitate the fixed installation of the mounting bracket 1.
[0028] The working principle of this utility model is as follows: Before use, the locking heads 52 on both sides engage with the slots 41, and the elastic balls are inserted into the grooves 42 to lock the squeegee 4 onto the mounting base 2. The spring 53 is in a compressed state, and the extension end of the electric cylinder 73 is in the middle position. During use, by controlling the extension of the electric cylinder 73, the rack 75 drives the first gear 71 to rotate counterclockwise and the second gear 72 to rotate clockwise, which in turn drives the mounting base 2 to rotate counterclockwise and the guide plate 6 to rotate clockwise. When the squeegee 4 prints to one side, the paste squeezed to both ends by the squeegee 4 is guided back to the screen printing area by the guide plate 6, preventing the paste from accumulating on both sides of the squeegee 4, improving printing quality, and reducing the labor intensity of printing workers. At the same time, controlling the extension of the electric cylinder 73 allows the squeegee 4 to perform printing operations on the other side. Furthermore, by controlling the extension and retraction of the electric cylinder 73, the angle of the squeegee 4 can be adjusted, making it easier for the squeegee 4 to perform reciprocating printing operations on the screen, thus increasing its practicality.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
