This completes the installation and replacement of the printing screen body 103, which is very convenient and quick.

[0024] The mounting plate 104 is fixedly connected to the bottom mounting bracket 102 and located on one side of the bottom mounting bracket 102. The guide plate 105 is fixedly connected to the bottom mounting bracket 102 and located on the side of the bottom mounting bracket 102 away from the mounting plate 104. The moving component is disposed on the mounting plate 104, the driving component is disposed on the mounting plate 104, and the scraping component is disposed on the printing screen body 103. The mounting plate 104 is welded to the front side of the bottom mounting bracket 102. The moving component is disposed on the lower surface of the mounting plate 104. The driving component is disposed on the mounting plate 104. When the driving component is activated, it drives the moving component to move on the mounting plate 104. The guide plate 105 is welded to the side of the bottom mounting bracket 102 away from the mounting plate 104. The guide plate 105 is used in conjunction with the moving component. The scraping component is provided in the placement slot of the bottom mounting bracket 102. The end of the scraping component is connected to the moving component, so that when the moving component moves on the mounting plate 104, it drives the scraping component to move within the placement slot of the bottom mounting bracket 102. This allows the scraping component to continuously wipe the surface of the printing screen body 103, thereby achieving a cleaning effect. After the screen is operated, the mounting plate 104 is set on the bottom mounting bracket 102, and the driving component is activated. The driving component drives the moving component to move horizontally on the mounting plate 104, causing the moving component to drive the scraping component to move within the placement slot of the bottom mounting bracket 102. This allows the scraping component to continuously wipe the surface of the printing screen body 103, thereby automatically cleaning the screen, reducing manual labor intensity, and improving work efficiency.

[0025] Secondly, the track 106 is disposed on the mounting plate 104; the slider 107 is slidably connected to the track 106 and is located on one side of the track 106. The track 106 is transversely disposed on the lower surface of the mounting plate 104. The length of the track 106 is adapted to the length of the placement groove of the bottom mounting bracket 102. The slider 107 is located inside the track 106. The cross-sectional dimensions of the slider 107 are adapted to the cross-sectional dimensions of the track 106, so that the slider 107 can move along the direction of the track 106 inside the track 106. The slider 107 is connected to the scraping component, so that when the slider 107 moves, it drives the scraping component to move.

[0026] Meanwhile, the small motor 108 is fixedly connected to the mounting plate 104 and located on one side of the mounting plate 104; the drive rod 109 is threadedly connected to the slider 107 and fixedly connected to the output end of the small motor 108. The small motor 108 is fixed to the right side of the mounting plate 104 by bolts. The output end of the small motor 108 passes through the mounting plate 104 into the track 106. The drive rod 109 is located in the track 106. The slider 107 is penetrated by the drive rod 109. One end of the drive rod 109 is fixed together with the output end of the small motor 108, so that when the small motor 108 starts, it drives the drive rod 109 to rotate. Under the threaded drive of rotating the drive rod 109, the slider 107 moves in the track 106 along the direction of the track 106, thereby driving the scraping assembly to move.

[0027] Additionally, the scraper 110 is slidably connected to the printing screen body 103 and located on one side of the printing screen body 103; the connecting rod 111 is fixedly connected to the scraper 110 and to the slider 107.

The scraper 110 is fixed to the inner surface of the connecting rod 111. The scraper 110 is located in the placement groove of the bottom mounting bracket 102. After the printing screen body 103 is installed, the scraper 110 abuts against the printing screen body 103, so that when the slider 107 moves, it drives the scraper 110 to move, causing the scraper 110 to move back and forth on the surface of the printing screen body 103, thereby scraping away the dust on the surface of the printing screen body 103 and playing a cleaning role.

[0028] Finally, the ball bearing 112 is rotatably connected to the connecting rod 111 and abuts against the guide plate 105. The end of the connecting rod 111 away from the slider 107 has a rotating groove, and three-quarters of the volume of the ball bearing 112 is located in the rotating groove, so that the ball bearing 112 can rotate at the end of the connecting rod 111. The end of the ball bearing 112 away from the connecting rod 111 abuts against the guide plate 105, so that when the slider 107 drives the connecting rod 111 to move, the ball bearing 112 moves on the guide plate 105, thereby guiding the movement of the connecting rod 111 and making it easier to drive the scraper 110 to clean the surface of the printing screen body 103.

[0029] In this embodiment, during use, after the screen has finished its work, the drive assembly is activated by setting the mounting plate 104 on the bottom mounting bracket 102. The drive assembly drives the moving assembly to move horizontally on the mounting plate 104, causing the moving assembly to move the scraping assembly within the placement groove of the bottom mounting bracket 102. This allows the scraping assembly to continuously wipe the surface of the printing screen body 103, thereby automatically cleaning the screen, reducing manual labor intensity, and improving work efficiency.
