Technical Field

[0001] This utility model relates to the technical field of plastic sheet production equipment, specifically to a de-edge removal device for plastic sheet production. Background Technology

[0002] In the production of plastic sheets, various raw materials in a certain metering ratio are melted at high temperature, extruded, calendered, cooled and molded, and cut to form the final product. However, after calendering, the edges of plastic sheets are usually difficult to make flat. An edge trimming device is needed to cut off the waste material at the edges of the plastic sheet to make the edges of the plastic sheet flat.

[0003] However, existing technologies still have the following problems:

[0004] First, existing devices for removing edges from plastic sheets generally do not have a structure for positioning the plastic sheet. During the edge removal operation, the plastic sheet is prone to movement, making the edge removal position of the device inaccurate and reducing the edge removal effect.

[0005] Secondly, existing edge trimming devices generally use a straight blade to cut the plastic sheet, which can easily damage the placement platform and makes it difficult to separate the plastic sheet from the scrap. Utility Model Content

[0006] To address the problems of existing edge-removal devices that easily cause plastic sheet movement, damage to the placement table during edge-removal, and difficulty in separating the plastic sheet from the scrap material when performing edge-removal operations, the purpose of this utility model is to provide an edge-removal device for plastic sheet production.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a de-edge removal device for plastic sheet production, comprising a worktable, a through groove on one side of the top of the worktable, a de-edge removal component on the inner wall of the through groove, a placement platform slidably connected to the top of the worktable, a positioning mechanism on one side of the top of the placement platform, the positioning mechanism comprising a bracket, the bottom end of the bracket being fixedly connected to one side of the top of the placement platform, a cylinder being fixedly connected to the top of the bracket, and the output end of the cylinder passing through the top of the bracket and fixedly connected to a connecting plate, one end of the connecting plate being slidably connected to one side of the inner wall of the bracket, and three positioning plates being fixedly connected to the bottom end of the connecting plate.

[0008] Preferably, the trimming assembly includes a housing, one end of which is fixedly connected to the inner wall of one side of the through groove. A motor is fixedly connected to the top of the housing, and the output end of the motor passes through the top of the housing and is fixedly connected to a round rod. Two worm gears are fixedly sleeved on the outer surface of the round rod, and worm wheels are meshed on the outer surfaces of the two worm gears. The threads on the outer surfaces of the two worm gears are arranged in opposite directions, and the threads on the outer surfaces of the two worm gears are respectively matched with the threads on the outer surfaces of the two worm wheels. Two rotating rods that cooperate with the two worm wheels are rotatably connected to the inner wall of one side of the housing. The two worm wheels are respectively fixedly sleeved on the outer surfaces of the two rotating rods. A first trimming cutter and a second trimming cutter are respectively fixedly connected to one end of the two rotating rods.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This application, through the setting of the positioning mechanism structure, can stably position the cut plastic sheet, preventing the plastic sheet from moving during edge trimming. The structure is simple and practical, thereby improving the edge trimming accuracy of the edge trimming device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-3 As shown, this utility model provides a de-edge removal device for plastic sheet production, including a workbench 1. A through groove 7 is formed on one side of the top of the workbench 1, and a de-edge removal component 3 is provided on the inner wall of the through groove 7. A placement platform 4 is slidably connected to the top of the workbench 1. A positioning mechanism 2 is provided on one side of the top of the placement platform 4. The positioning mechanism 2 includes a bracket 26. The bottom end of the bracket 26 is fixedly connected to one side of the top of the placement platform 4. A cylinder 25 is fixedly connected to the top of the bracket 26, and the output end of the cylinder 25 passes through the top of the bracket 26 and is fixedly connected to a connecting plate 24. One end of the connecting plate 24 is connected to the bracket 26. The inner wall of one side is slidably connected, and three positioning plates 23 are fixedly connected to the bottom end of the connecting plate 24. The plastic sheet to be trimmed is placed in a suitable position on the placement platform 4. Then, the cylinder 25 is activated through the positioning mechanism 2. The output end of the cylinder 25 drives the connecting plate 24 to move downward. The movement of the connecting plate 24 drives the three positioning plates 23 to move downward synchronously to position the plastic sheet, so as to prevent the plastic sheet from moving during trimming and affecting the trimming effect. At the same time, the trimming component 3 is activated. By manually pulling the placement platform 4, the plastic sheet on the placement platform 4 moves towards the trimming component 3 to perform a fast trimming operation on the plastic sheet, thereby improving the trimming effect of the trimming device.

[0019] The edge-removing assembly 3 includes a housing 31. One end of the housing 31 is fixedly connected to the inner wall of one side of the through groove 7. A motor 39 is fixedly connected to the top of the housing 31, and the output end of the motor 39 passes through the top of the housing 31 and is fixedly connected to a round rod 38. Two worm gears 37 are fixedly sleeved on the outer surface of the round rod 38, and worm wheels 36 are meshed on the outer surfaces of the two worm gears 37. Two rotating rods 35 are rotatably connected to the inner wall of one side of the housing 31, which cooperate with the two worm wheels 36. The two worm wheels 36 are respectively The two rotating rods 35 are fixedly sleeved on their outer surfaces. One end of each of the two rotating rods 35 is fixedly connected to a first trimming blade 32 and a second trimming blade 34. When the motor 39 is started, the output end of the motor 39 drives the round rod 38 to rotate. The rotation of the round rod 38 drives the two worm gears 37 to rotate synchronously. The synchronous rotation of the two worm gears 37, in conjunction with the worm wheel 36, causes the two rotating rods 35 to rotate synchronously. The synchronous rotation of the two rotating rods 35 drives the first trimming blade 32 and the second trimming blade 34 to move towards their opposite surfaces to perform a better trimming operation on the plastic sheet.

[0020] The bottom of all three positioning plates 23 is made of anti-slip material, which makes the positioning plate 23 more effective in positioning the plastic sheet.

[0021] The top side of the workbench 1 is provided with a guide groove 6. The inner walls of both sides of the guide groove 6 are slidably connected with a connector 5. The upper part of one end of the connector 5 is fixedly connected to one end of the placement platform 4. The lower inner walls of the connector 5 are slidably connected to the bottom end of the workbench 1. The guide groove 6, in conjunction with the connector 5, serves to guide the movement of the placement platform 4 when it is pulled.

[0022] One end of the connecting plate 24 is fixedly connected to a locking block 22. One end of the bracket 26 is provided with a slot 21 for use with the locking block 22. The end of the locking block 22 facing away from the connecting plate 24 passes through the slot 21. The two ends of the locking block 22 are slidably connected to the inner walls of the two sides of the slot 21. The locking block 22 is T-shaped. The slot 21 is used in conjunction with the locking block 22 to facilitate the movement of the connecting plate 24.

[0023] The top height of the placement platform 4 is level with the top height of the second edge-removing blade 34, which facilitates the edge-removing assembly 3 to remove the edges of the plastic sheet on the placement platform 4.

[0024] The outer surfaces of the two worm gears 37 have opposite thread directions, and the threads on the outer surfaces of the two worm gears 37 are respectively matched with the threads on the outer surfaces of the two worm wheels 36. This facilitates the rotation of the round rod 38 to drive the two worm gears 37 to rotate synchronously, so that the two worm wheels 36 can rotate in different directions. This also facilitates the cooperation of the first trimming cutter 32 and the second trimming cutter 34 connected to the two rotating rods 35 to trim the plastic sheet.

[0025] The top of the workbench 1 is provided with a through vertical groove 33 for use with the second edge-removing blade 34, and the second edge-removing blade 34 passes through the vertical groove 33. The inner wall size of the vertical groove 33 is larger than the outer surface size of the second edge-removing blade 34. The vertical groove 33 prevents the workbench 1 from affecting the rotation of the second edge-removing blade 34.

[0026] Working principle: First, place the plastic sheet to be trimmed in a suitable position on the placement platform 4. Then, through the positioning mechanism 2, start the cylinder 25. The output end of the cylinder 25 drives the connecting plate 24 to move up and down. The slot 21 works with the block 22 to guide the connecting plate 24 when it moves.

[0027] The moving connecting plate 24 causes the three positioning plates 23 to move downwards synchronously, positioning the plastic sheet in a suitable position on the placement platform 4.

[0028] Then, by using the edge removal component 3, the motor 39 is started. The output end of the motor 39 drives the round rod 38 to rotate. When the round rod 38 rotates, it drives the two worm gears 37 to rotate synchronously. The two worm wheels 36 rotate in different directions.

[0029] The two rotating rods 35 rotate synchronously, driving the first trimming cutter 32 and the second trimming cutter 34 to move towards the opposite surface respectively. The vertical groove 33 prevents the worktable 1 from affecting the rotation of the second trimming cutter 34.

[0030] At the same time, the placement table 4 is moved by manually pulling it through the guide groove 6 and the connector 5, so that the plastic sheet on the placement table 4 moves toward the first edge-removing blade 32 and the second edge-removing blade 34 in the edge-removing assembly 3.

[0031] Next, the plastic sheet is quickly trimmed by the high-speed rotation of the first trimming blade 32 and the second trimming blade 34.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
