Description

Technical Field

[0001] This utility model relates to the field of plastic sheet production, and specifically to a diagonal adjustment device for plastic sheets. Background Technology

[0002] In the production of plastic sheets, diagonal dimensional errors are a common quality problem. Currently, the industry typically adjusts the diagonal dimensions by adjusting the pressure of the cylinders on both sides of the equipment. However, this method has significant drawbacks: firstly, the adjustment process is time-consuming, requiring operators to repeatedly adjust the pressure and measure dimensions, greatly reducing production efficiency; secondly, it generates a large amount of waste during the adjustment process, increasing production costs and hindering the company's economic benefits and sustainable development. Therefore, there is an urgent need for a device that can quickly and accurately adjust the diagonal dimensions of plastic sheets and reduce waste generation. Utility Model Content

[0003] The purpose of this invention is to provide a diagonal adjustment device for plastic sheets, which solves the problems of multiple steps, low efficiency and high cost in the current process of solving the quality problem of diagonal error in plastic sheets.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A diagonal adjustment device for plastic sheets includes a roller with adjustment components on both sides. Each adjustment component has a fixed frame, a lead screw, a nut, and a movable block. The lead screw is rotatably connected to the fixed frame, and the movable block is mounted on the lead screw via the nut. The roller is hinged to the movable block. Rotation of the lead screw causes the movable block, connected to the nut, to move the roller up and down.

[0005] Furthermore, the fixed frame is provided with a guide member, and the front and rear ends of the movable block are respectively provided with grooves adapted to the guide member; the movable block can move up and down along the guide member.

[0006] Furthermore, a handwheel is provided at the top of the lead screw, and the bottom of the lead screw is connected to the fixed frame via a bearing.

[0007] Furthermore, the movable block has a hinge seat with a hinge hole, and the two ends of the roller have connection holes corresponding to the hinge hole.

[0008] Compared with the prior art, this utility model has the following advantages and beneficial effects: The diagonal adjustment device of this invention is installed between the traction machine and the shearing machine, and is mounted on a bracket between the two machines. When the traction force provided by the traction machine cylinder to the sheet metal varies, a large diagonal error may occur. In this case, the height of the idler roller is adjusted according to the diagonal error. The idler roller is adjusted higher on the side with the shorter diagonal and lower on the side with the longer diagonal. By applying different supporting forces to the sheet metal with the idler rollers, the horizontal pulling force provided by the cylinder to the sheet metal is changed, thus achieving the purpose of adjusting the diagonal of the sheet metal. This invention can adjust the diagonal of the sheet metal without adjusting the cylinder, and can keep the diagonal within an acceptable error range. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of a diagonal adjustment device for plastic sheets. Detailed Implementation

[0010] like Figure 1 As shown, a diagonal adjustment device for plastic sheets includes a roller 1, with adjusting components on both sides of the roller 1. Each adjusting component has a fixed frame 2, a lead screw 3, a nut, and a moving block 4. The lead screw 3 is rotatably connected to the fixed frame 2, and the moving block 4 is mounted on the lead screw 3 via the nut. The roller 1 is hinged to the moving block 4. Rotation of the lead screw 3 causes the moving block 4, connected to the nut, to move the roller 1 up and down. This device is installed on a bracket between a traction machine and a shearing machine. The plastic sheet moves towards the shearing machine under the traction of the traction machine. When the diagonals of the plastic sheet are unequal, the roller 1 is raised via a handwheel 5. The side with the shorter diagonal has a higher corresponding side of the roller 1, and the side with the longer diagonal has a lower corresponding side of the roller 1. The higher side of the roller 1 increases the horizontal tension of the plastic sheet, while the lower side of the roller 1 has a smaller horizontal tension relative to the other side, thus reducing the diagonal error between the plastic sheets.

[0011] The fixed frame 2 is equipped with a guide member 6, and the front and rear ends of the movable block 4 are respectively provided with grooves adapted to the guide member 6; the movable block 4 can move up and down along the guide member 6. The top of the lead screw 3 is provided with a handwheel 5, and the bottom of the lead screw 3 is connected to the fixed frame 2 through a bearing. The movable block 4 has a hinge seat 7, and the hinge seat 7 is provided with a hinge hole. The two ends of the idler roller 1 are provided with connection holes adapted to the hinge hole. If the diagonal dimension of one side of the board is too small, the height of the idler roller 1 at the corresponding position can be appropriately reduced, so that the board at that corner is subjected to greater tension when passing through the idler roller 1, thereby stretching the board and adjusting the diagonal dimension. Before the idler roller 1 starts working, a roller needs to be sleeved on the idler roller 1. The roller can rotate relative to the idler roller 1 to improve the transport efficiency of the board and reduce the friction of the board, thus protecting the board.

[0012] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
