Description

Technical Field

[0001] This utility model relates to the field of winding and correction technology, specifically a winding and correction protection device for plastic products. Background Technology

[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer. During the production and winding of plastic film, it is necessary to correct and protect the two sides of the plastic film. Therefore, a correction and protection device for winding plastic products is provided.

[0003] For example, a web-aligning protector for winding plastic products, with announcement number "CN221662134U," uses a web-aligning structure, along with a movable plate and shafts, to adjust the winding specifications of the PVC film according to its size, preventing misalignment during winding. The protective plate also supports the bottom of the PVC film during winding, preventing uneven tension due to increased thickness, which could further cause winding deviations. However, during the winding process, because the movable shafts on both sides remain in contact with the film on the winding roller, the shafts rub against the film for extended periods, damaging it and reducing its quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when the movable shafts on both sides are kept in contact with the plastic film on the take-up roller, the movable shafts will rub against the plastic film on the take-up roller for a long time, which will damage the plastic film and reduce the quality of the plastic film. Therefore, a correction and protection device for winding plastic products is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a plastic product winding correction and protection device, including a base plate and a vertical plate. The upper right side of the outer wall of the base plate is fixedly connected to the vertical plate. The left side of the inner wall of the vertical plate is provided with a plastic product winding adjustment structure. A motor is fixedly connected to the right side of the outer wall of the vertical plate. A rotating shaft is fixedly connected to the outer wall of the motor through a bracket. The right end of the rotating shaft is rotatably connected to the vertical plate through a bearing. A plastic product winding correction structure is provided on the left side of the rotating shaft. A sleeve is provided on the left side of the outer wall of the rotating shaft. Multiple grooves are machined on both sides of the sleeve.

[0007] Preferably, the plastic product winding adjustment structure includes an electric telescopic rod, the output end of which is fixedly connected to a crossbar, the outer wall of which is rotatably connected to a cylinder via a bearing, the two cylinders being slidably connected to a groove machined on the inner wall of the first turntable, and two first insert rods being fixedly connected to the left side of the outer wall of the first turntable.

[0008] Preferably, the two first insert rods abut against the groove on the right side of the sleeve, and the bottoms of the two electric telescopic rods are fixedly connected to the vertical plate.

[0009] Preferably, the plastic product winding and correction structure includes a circular plate, with bolts fixedly connected to the middle of the inner wall of the circular plate. The inner wall of the circular plate is rotatably connected to the second turntable via a bearing. Two second insert rods are fixedly connected to the right side of the outer wall of the second turntable, and the outer walls of the second insert rods abut against the groove on the left side of the sleeve.

[0010] Preferably, the outer wall of the bolt is threaded to the shaft, and the lower end of the outer wall of the base plate is machined with anti-slip texture.

[0011] The present invention provides a correction and protection device for winding plastic products, which has the following advantages: Through the plastic product winding correction structure, two electric telescopic rods are activated, driving the crossbar and cylinder to move to the left. The cylinder then drives the first turntable to move to the left, and the first turntable drives the two first insert rods to insert into the groove on the right side of the sleeve. When the first insert rods abut against the groove on the right side of the sleeve, the electric telescopic rods stop moving. The electric telescopic rods drive the first turntable to move, adjusting the distance between the first and second turntables. This device is suitable for winding plastic films of different widths, thereby improving practicality.

[0012] Through the plastic product winding adjustment structure, the rotation of the sleeve drives the second turntable to rotate synchronously with the sleeve within the circular plate via bearings, through the second insert rod. Simultaneously, the first turntable rotates synchronously with the sleeve on the outer walls of the two cylinders via the first insert rod. The inner wall of the first turntable is machined with an annular groove, thereby enabling circumferential rotation. The rotation of the first turntable drives the cylinder to rotate on the outer wall of the crossbar via bearings. The first and second turntables limit and pull the plastic film on both sides, thus playing a role in correcting deviation. At the same time, during the winding process of the plastic film, the first and second turntables rotate with the sleeve, effectively reducing friction on both sides of the plastic film, thereby reducing damage to the plastic film and improving the quality of use of the plastic film.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] See attached document Figure 1-7 In this embodiment, a correction and protection device for winding plastic products includes a base plate 3 and a vertical plate 4. The upper right side of the outer wall of the base plate 3 is fixedly connected to the vertical plate 4. A plastic product winding adjustment structure 2 is provided on the left side of the inner wall of the vertical plate 4. A motor 5 is fixedly connected to the right side of the outer wall of the vertical plate 4. The motor 5 is a servo motor. A rotating shaft 7 is fixedly connected to the outer wall of the motor 5 through a bracket. The right end of the rotating shaft 7 is rotatably connected to the vertical plate 4 through a bearing.

[0023] Motor 5 can drive shaft 7 to rotate within vertical plate 4 via bearings. Shaft 7 has a plastic product winding and correction structure 1 on its left side. Shaft 7 has a sleeve 6 on its left outer wall. Multiple grooves 8 are machined on both sides of sleeve 6. Two first insert rods 205 abut against the groove on the right side of sleeve 6. The bottom of two electric telescopic rods 201 are fixedly connected to vertical plate 4. Bolt 102 is threadedly connected to shaft 7 on its outer wall. Anti-slip texture is machined on the lower end of the outer wall of base plate 3.

[0024] See attached document Figure 1-3 7: The plastic product winding adjustment structure 2 includes an electric telescopic rod 201. The electric telescopic rod 201 can meet the actual needs of the work. The output end of the electric telescopic rod 201 is fixedly connected to a crossbar 202. The outer wall of the crossbar 202 is rotatably connected to a cylinder 203 through a bearing. The cylinder 203 can rotate on the outer wall of the crossbar 202 through the bearing. The two cylinders 203 are slidably connected to the groove processed on the inner wall of the first turntable 204. The two cylinders 203 can slide in the groove processed on the inner wall of the first turntable 204. Two first insert rods 205 are fixedly connected to the left side of the outer wall of the first turntable 204.

[0025] See attached document Figure 1-25-6: The plastic product winding and correction structure 1 includes a circular plate 101. A bolt 102 is fixedly connected to the middle of the inner wall of the circular plate 101. The inner wall of the circular plate 101 is rotatably connected to the second turntable 103 through a bearing. The second turntable 103 can rotate inside the circular plate 101 through the bearing. Two second insert rods 104 are fixedly connected to the right side of the outer wall of the second turntable 103. The outer wall of the second insert rod 104 abuts against the groove on the left side of the sleeve 6.

[0026] Working principle:

[0027] Plastic product winding and alignment adjustment:

[0028] When it is necessary to correct the alignment of plastic products (plastic film), rotate the circular plate 101 outward, which in turn drives the bolt 103 to rotate, disengaging it from the rotating shaft 7. Then, insert the sleeve 6 onto the rotating shaft 7. Further rotate the circular plate 101 inward to turn the bolt 102 into the rotating shaft 7 for fixation. This movement limits the movement of the sleeve 6. Then, insert the groove 8 on the left side of the sleeve 6 into the two second insert rods 104. Then, connect the power cords of the two electric telescopic rods 201 to the control board simultaneously, and simultaneously connect the external power supply of the two electric telescopic rods 201. When the electric telescopic rod 201 is started, it drives the crossbar 202 and the cylinder 203 to move to the left. In turn, the cylinder 203 drives the first turntable 204 to move to the left. The first turntable 204 then drives the two first insert rods 205 to be inserted into the groove 8 on the right side of the sleeve 6. When the first insert rods 205 abut against the groove 8 on the right side of the sleeve, the electric telescopic rod 201 stops moving. This movement can adjust the distance between the first turntable 204 and the second turntable 103, thereby limiting the sleeve 6. By adjusting the distance between the first turntable and the second turntable 103, it can be used for sleeves 6 of different lengths.

[0029] Plastic product winding and straightening work:

[0030] After the sleeve 6 is positioned, one end of the plastic film is removed and wound onto the sleeve 6. Then, the external power supply to the motor 5 is connected. The motor 5 starts, driving the rotating shaft 7 to rotate within the vertical plate 4 via bearings. This, in turn, drives the sleeve 6 to rotate, thus enabling the sleeve 6 to wind up the plastic film. During the rotation of the sleeve 6, the second insert rod 104 drives the second turntable 103 to rotate synchronously with the sleeve 6 within the circular plate 101 via bearings. Simultaneously, the first insert rod 205 drives the first turntable 204 to rotate synchronously with the sleeve 6 on the outer walls of the two cylinders 203. 4. The inner wall is machined with an annular groove, which enables circumferential rotation. The rotation of the first turntable 204 drives the cylinder 204 to rotate on the outer wall of the crossbar 202 via bearings. The first turntable 204 and the second turntable 103 limit and pull the plastic film on both sides, thereby playing a corrective role. When the plastic film is wound to a sufficient length and needs to be removed, it can be removed in the same way as the sleeve 6 described above. At the same time, during the winding of the plastic film, the first turntable 204 and the second turntable 103 will rotate with the sleeve 6, effectively reducing the friction on both sides of the plastic film, thereby reducing damage to the plastic film.

[0031] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
