The L-shaped plate 2 includes a vertically arranged vertical plate and a horizontally arranged horizontal plate. Above the horizontal plate, a threaded rod 21 is vertically arranged. A threaded slide rod 22 is sleeved on the outer side of the threaded rod 21. The threaded slide rod 22 movably penetrates through the tabletop of the operating table 1. When the threaded rod 21 rotates, it drives the threaded slide rod 22 to rotate and move up and down at the same time. The top end of the threaded slide rod 22 passing through the tabletop of the operating table 1 is provided with a second mounting plate 23, and a bearing plate 24 is installed at the top end of the second mounting plate 23; the screen printing mechanism 16 is facing the bearing plate 24 on the tabletop of the operating table 1. The bearing plate 24 is used to carry a stack of multiple metal plates and drive the metal plates to move upward at the same time.

[0025] A rotating rod 3 is rotatably provided on the outer side of the side plate 11. A gear 31 is provided on the rotating rod 3. Two tooth plates 32 are respectively slidably provided near the vertically arranged gear 31 at the upper and lower ends of the side plate 11. The two tooth plates 32 are respectively meshed with the upper and lower sides of the gear 31. Clamping plates 33 are fixedly provided on the outer sides of the two tooth plates 32. Two square grooves 34 are opened in the side plate 11. The two clamping plates 33 respectively pass through their corresponding square grooves 34 and are fixedly connected with the opposite tooth plates 33. On the tabletop of the operating table 1, tracks for the relative sliding of the two clamping plates 33 can also be provided to facilitate the relative movement of the clamping plates 33.

[0026] By adopting the above technical solution, the rotation of the rotating rod 3 drives the clamping plate 33 to move, so that the metal plate can be clamped and limited, avoiding the problem of manually aligning the metal plate multiple times.

[0027] The second mounting plate 23 and the bearing plate 24 are installed and connected by screws. The first mounting plate 15 and the screen printing mechanism 16 are installed and connected by screws. By adopting this method, the bearing plate 24 and the screen printing mechanism 16 can be installed and disassembled.

[0028] At the bottom end of the operating table 1, support legs 18 distributed in a rectangular array are fixedly provided. A baffle 17 is installed on the inner side of the side plate 11. The baffle 17 is facing the bearing plate 24. By adopting this method, the support legs 18 support the whole device, and the baffle 17 limits the metal plate and assists in positioning the metal plate.

[0029] A limiting rod 26 is fixedly arranged between the horizontal plate of the L-shaped plate 2 and the operating table. The limiting rod 26 is arranged parallel to the threaded rod 21 and the threaded sliding rod 22 respectively. A limiting plate 25 is arranged outside the threaded sliding rod 22. The limiting plate 25 is movably sleeved on the limiting rod 26 and slides up and down along the limiting rod 26. By adopting this method, the limiting plate 25 and the limiting rod 26 assist the threaded sliding rod 22 to move up and down.

[0030] A first motor 27 is installed at the bottom of the horizontal plate of the L-shaped plate 2. The end of the output shaft of the first motor 27 penetrates through the horizontal plate and is fixedly connected to the bottom end of the threaded rod 21. By adopting this method, the end of the output shaft of the first motor 27 drives the threaded rod 21 to rotate, which is used to provide power output and drive the threaded sliding rod 22 to move up and down.

[0031] Sliding tracks 35 are respectively arranged at the upper and lower ends outside the side plate 11. Two toothed plates 32 are respectively arranged on the two sliding tracks 35; the toothed plate 32 is arranged parallel to the corresponding square groove 34. By adopting this method, the sliding track 35 can limit the toothed plate 32, so that the toothed plate 32 moves in the sliding track 5.

[0032] A second motor 36 is installed outside the support plate 12. The end of the output shaft of the second motor 36 passes through the support plate 12 and is fixedly connected to the rotating rod 3. By adopting this method, the end of the output shaft of the second motor 36 rotates to drive the rotating rod 3 to rotate, thereby driving the two toothed plates 32 to move towards each other, and thus driving the two clamping plates 33 to move towards each other.

[0033] Working principle: First, the metal plates to be processed are stacked on the bearing plate 24. Then, the second motor 36 is started. The end of the output shaft of the second motor 36 rotates to drive the rotating rod 3 to rotate. The rotating rod 3 rotates to drive the gear 31 to rotate. The gear 31 rotates to drive the two mutually meshing toothed plates 32 to move towards the opposite side with the assistance of the interactive track 35, and then the two clamping plates 33 can be driven to move towards the metal plate, so as to clamp the metal plate, avoiding the problem that the metal plates need to be positioned manually one by one. Then, the top metal plate can be printed by the screen printing mechanism 16. After printing, the first motor 27 can be started. The end of the output shaft of the first motor 27 rotates to drive the threaded rod 21 to rotate. The threaded rod 21 rotates to drive the threaded sliding rod 22 to move upward with the assistance of the limiting plate 25 and the limiting rod 26. Then, the second mounting plate 23 and the bearing plate 24 can be moved upward, so as to move the metal plate upward, making the printed metal plate higher than the clamping plate 33, and the printed metal plate can be taken down. Then, the metal plate can be printed continuously, avoiding the problems of low efficiency and troublesome operation caused by manual feeding multiple times.
