Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 5 , the utility model provides an embodiment: a screen printing machine feeding mechanism, including a screen printing machine body 3, a workbench 5 is fixedly connected to the upper end of the screen printing machine body 3, a placing table 4 is movably provided on the upper end of the workbench 5, a partition 2 is fixedly connected to the rear end of the screen printing machine body 3, a cleaning tank 1 is fixedly connected to the upper end of the cleaning tank 1, a fixed frame 6 is fixedly connected to both sides of the fixed frame 6, two slide rails 7 are provided, a feeding frame 10 is movably provided between the front and rear slide rails 7, a push-pull rod 8 is movably provided in the middle of the upper end of the fixed frame 6, and a suction cup 9 is fixedly connected to the lower end of the push-pull rod 8. When the overall device is used, the plate parts and other items to be printed are placed on the placing table 4 during its use, and the placing table 4 slides from the feeding frame 10 to the upper end of the workbench 5, wherein both sides of the workbench 5 are provided with positioning structures, so that the placing table 4 can realize the positioning function at the upper end of the workbench 5;

[0022] Positioning blocks 12 are fixedly connected to both sides of the upper end of the loading rack 10, and long springs 11 are connected to both sides of the lower end of the loading rack 10. The cleaning pool 1 is filled with cleaning liquid. A rectangular through hole is penetrated through the partition 2 near the middle. The front end of the loading rack 10 is aligned with the rectangular through hole, and the cross-sectional surface of the entire loading rack 10 is set as an L-shaped structure. This setting enables the placement table 4 to slide onto the horizontal plate of the loading rack 10, thereby further improving the support and limit of the placement table 4 by the loading rack 10, wherein the positioning block 12 at the upper end of the loading rack 10 has a positioning function for the placement table 4;

[0023] When the whole placing table 4 moves onto the loading rack 10, the positioning block 12 first positions the placing table 4 so that the placing table 4 cannot move up and down on the loading rack 10. Then the user pushes the whole push-pull rod 8, so that the push-pull rod 8 drives the suction cup 9 at the lower end to be close to the upper end of the placing table 4, and the suction cup 9 sucks the upper end of the placing table 4. The user pulls the push-pull rod 8 to move up and down, so that the whole placing table 4 moves up and down in the cleaning tank 1. During the up and down movement of the placing table 4 in the cleaning tank 1, the cleaning liquid inside the cleaning tank 1 flushes and cleans the ink on the surface of the placing table 4. The lower end of the loading rack 10 is also fixedly connected with two long springs 11. The elasticity of the long springs 11 increases the frequency of the vertical movement of the loading rack 10, and also increases the frequency of the vertical movement of the placing table 4 on the loading rack 10, thereby greatly improving the efficiency of cleaning the placing table 4 inside the cleaning tank 1.
