This patent achieves the purpose of convenient adjustment through the arrangement of the plate body, sliding plate, sliding groove, sliding block, vertical plate, support plate, threaded tube, telescopic bracket, limiting rod, threaded rod, driven gear, motor and driving gear.

[0004] The common problem with the plastic sheet positioning bracket in the aforementioned patent and similar devices on the market is that it cannot slowly position the sheet from the side during the positioning process, which prevents the material from being suddenly subjected to external forces and thus reduces the positioning effect of the plastic sheet. Utility Model Content

[0005] To address the aforementioned issues, a positioning bracket for processing plastic sheets is provided. This bracket enables a horizontal movement of an adjusting plate, which in turn moves a pressure plate. The pressure plate is elastic and can slowly compress the plastic sheet during positioning. Furthermore, a U-shaped plate can rotate, allowing the other side of the plastic sheet to be positioned under its influence. The U-shaped plate also possesses a certain degree of elasticity. Through the cooperation of the U-shaped plate and the pressure plate, the plastic sheet can be positioned more stably, and its material will not be suddenly altered by external forces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning bracket for processing plastic sheets, comprising a worktable, a movable plate, a positioning roller, a placement plate, an adjusting plate, a pressure plate, and a U-shaped plate. The movable plate is positioned above the worktable, the positioning roller is positioned above the movable plate, the placement plate is positioned on top of the worktable, the adjusting plate is positioned above the worktable, the pressure plate is positioned above the adjusting plate, and the U-shaped plate is positioned on one side of the pressure plate.

[0007] Furthermore, a guide groove is provided at the top center of the workbench, and a limiting slider connected to the adjusting plate is slidably connected inside the guide groove.

[0023] The movable plate 2 can move horizontally on the top of the workbench 1. When the movable plate 2 moves, it can drive the positioning roller 3 to move. The horizontal adjustment of the positioning roller 3 can position the side of the plastic sheet. Then, the adjusting plate 5 moves horizontally. When the adjusting plate 5 moves, it drives the pressure plate 6 to move. The pressure plate 6 is elastic and can slowly squeeze the plastic sheet when positioning it. The U-shaped plate 7 can rotate and can position the other side of the plastic sheet under the action of the U-shaped plate 7. The U-shaped plate 7 also has a certain degree of elasticity. Through the cooperation of the U-shaped plate 7 and the pressure plate 6, the plastic sheet can be more stable when positioned, and its own material will not change suddenly due to external force.

[0024] like Figure 2 and Figure 3 As shown, a guide groove is provided at the top center of the workbench 1. A limiting slider 9 connected to the adjusting plate 5 is slidably connected inside the guide groove. A lead screw 10 is threaded through the inside of the limiting slider 9. A crank handle 8 is provided at the input end of the lead screw 10.

[0025] Turning the crank handle 8 causes the lead screw 10 to rotate, which allows the limit slider 9 to slide inside the guide groove, thereby enabling the horizontal control of the adjusting plate 5 and facilitating the positioning of plastic sheets of different specifications.

[0026] like Figure 3 As shown, hollow rods 11 are symmetrically arranged on one side of the adjusting plate 5, and a plug rod 12 matching the hollow rods 11 is arranged on one side of the pressure plate 6. A return spring is arranged inside the hollow rods 11.

[0029] When the U-shaped plate 7 rotates, the connecting rod 14 will slide inside the hollow cylinder 13, which can compress the plastic sheet during positioning and improve the positioning quality.

[0030] like Figure 3 As shown, the U-shaped plate 7 has symmetrically arranged slots inside, and a limiting post 15 is arranged inside the slot. The top of the limiting post 15 is threadedly connected to a positioning plate 16.

[0031] The limiting post 15 can be installed using the slot, and then the limiting post 15 can be threaded onto the positioning plate 16, making it convenient for the user to install and remove the limiting post 15.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, a guide plate 17 is threadedly installed on the top of the workbench 1. A movable block connected to the movable plate 2 is provided on the top of the guide plate 17. A fixed plate is provided on the top of the workbench 1. The fixed plate and the movable plate 2 are connected by a hydraulic cylinder 18. A working plate 19 is provided on the top of the movable plate 2. The working plate 19 and the movable plate 2 are connected by a positioning roller 3.

[0033] When the hydraulic cylinder 18 is activated, it will drive the movable block to move horizontally on the top of the guide plate 17, thereby stabilizing the movable plate 2. Under the action of the movable plate 2, the positioning roller 3 can be installed. The positioning roller 3 can achieve side positioning of the plastic sheet and facilitate pushing the plastic sheet for feeding.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model.
