Description

Technical Field

[0001] This utility model relates to the field of release film processing, and in particular to a precision rewinding machine for release film processing. Background Technology

[0002] In the production of release film, the final step is to roll the release film onto a tube, which is then fitted onto the outside of an installation roller. The installation roller is driven by a motor to rotate, wrapping the release film layer by layer onto the tube for easy use and transportation. The installation roller has an internal clamping structure. By inflating the installation roller, the clamping block protrudes and presses against the inner wall of the tube, thus completing the installation of the tube and the installation roller.

[0003] During use, the inflation pipe of the inflation device is connected to the inflation port of the mounting roller, and then the inflation device is turned on to inflate the inside of the mounting roller. The gas pushes the clamping block to move. When the full material cylinder is removed, the gas inside the mounting roller needs to be discharged so that the clamping block is no longer pressed against the cylinder, and the cylinder can be removed and replaced with a new cylinder. This technology requires additional inflation equipment, which increases production costs. Moreover, as the amount of material outside the cylinder increases, the weight of the cylinder increases, which increases the pressure on the upper clamping block. This causes the clamping block to slide inside the mounting roller, making the cylinder unstable and moving outside the mounting roller. This affects the winding of the release film, resulting in an uneven winding section and a poor rewinding effect. Utility Model Content

[0004] In view of the problems in the above or existing technology where the weight of the material cylinder increases the pressure on the upper clamping block, causing the clamping block to slide inside the mounting roller, resulting in unstable installation of the material cylinder and movement outside the mounting roller, thus affecting the winding of the release film, causing uneven winding cross section and poor rewinding effect, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A disassembly component includes a rewinder body. An installation roller is located on the right side inside the rewinder body. A material cylinder is located outside the installation roller. A movable column is slidably connected left and right inside the installation roller. A rotating rod is movably installed inside the movable column. A support plate is movably connected to the end of the rotating rod away from the movable column. An anti-slip pad is fixedly connected to the outside of the support plate. A power assembly is located inside the movable column. A positioning component includes a synchronization column, which is fixedly connected to the right end of the power assembly. A slot is provided inside the support plate.

[0006] As a preferred embodiment of the precision rewinding machine for release film processing of this utility model, the power assembly includes three limiting blocks, all three limiting blocks are fixedly connected to the outside of the movable column, a rotating column is rotatably connected inside the movable column, a boss is threadedly connected to the outside of the rotating column, a tension spring is fixedly connected inside the movable column, an inclined block is fixedly connected to the end of the tension spring away from the movable column, and a positioning block is fixedly connected to the side of the inclined block away from the boss.

[0007] As a preferred embodiment of the precision rewinding machine for release film processing of this utility model, wherein: the boss is slidably connected to the inside of the movable column, the mounting roller and the positioning block are provided with positioning grooves at corresponding positions, and the rotating rod is in a vertical state when the positioning block is inserted into the slot.

[0008] As a preferred embodiment of the precision rewinding machine for release film processing of this utility model, wherein: the outer side of the support plate is arc-shaped and concentric with the material cylinder, the anti-slip pad is disposed between the material cylinder and the support plate, and the support plate is slidably connected to the inside of the mounting roller.

[0009] As a preferred embodiment of the precision rewinding machine for release film processing of this utility model, the limiting block is slidably connected to the inside of the mounting roller, and the operating disc is fixedly connected to the left end of the movable column.

[0010] As a preferred embodiment of the precision rewinding machine for release film processing of this utility model, wherein: a turntable is fixedly connected to the outside of the synchronization column, the number of the turntables is two, the other turntable is fixedly connected to the outside of the rotating column, and three insert blocks are fixedly connected to the inner side of each of the two turntables.

[0011] As a preferred embodiment of the precision rewinding machine for release film processing of this utility model, wherein: the insert block is inserted into the inside of the slot, and the turntable has an arc-shaped groove in the middle.

[0012] The beneficial effects of the precision rewinding machine for release film processing of this utility model are as follows:

[0013] 1. By disassembling the components, the rotating rod is driven by the movable column, causing the three support plates to unfold and abut against the inside of the cylinder. This fixes the cylinder to the outside of the mounting roller, allowing it to rotate synchronously to wind up the film. The rotating column drives the boss to push the inclined block, achieving the effect of the positioning block being inserted into the inside of the mounting roller to fix the position of the movable column. This makes the support plates rigidly fixed to the cylinder, avoiding the problem of the cylinder falling off due to the influence of temperature, air pressure, and the weight of the material outside the cylinder. This ensures that the installation of the cylinder and the mounting roller is always stable.

[0014] 2. By using the positioning component, the rotating column drives the turntable to rotate, so that the insert block is inserted into the slots at both ends of the support plate, which achieves the effect of reinforcing the support plate of the protruding mounting roller, providing better support for the material cylinder, and also reducing pressure and protecting the rotating rod.

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1, referring to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a precision rewinding machine for release film processing, which can achieve the effect of stable installation of the material cylinder 12. It includes a disassembly component and a rewinding machine body 10. An installation roller 11 is provided on the right side inside the rewinding machine body 10. The material cylinder 12 is provided outside the installation roller 11. A movable column 13 is slidably connected to the inside of the installation roller 11. A rotating rod 14 is movably installed inside the movable column 13. A support plate 15 is movably connected to the outside of the end of the rotating rod 14 away from the movable column 13. An anti-slip pad 16 is fixedly connected to the outside of the support plate 15. A power component 17 is provided inside the movable column 13.

[0025] Specifically, the power assembly 17 drives three support plates 15 to protrude slightly from the mounting roller 11 to fix the material cylinder 12. The anti-slip pad 16 is placed between the material cylinder 12 and the support plate 15 to increase the friction between the two, thereby making the material cylinder 12 firmly fixed to the outside of the mounting roller 11, so that the material cylinder 12 can follow the rotation of the mounting roller 11 to wind up the release film.

[0026] Furthermore, the power assembly 17 includes three limiting blocks 171, all of which are fixedly connected to the outside of the movable column 13. The movable column 13 is rotatably connected to a rotating column 172, and the rotating column 172 is threadedly connected to a boss 173. The movable column 13 is fixedly connected to a tension spring 174, and a wedge block 175 is fixedly connected to the end of the tension spring 174 away from the movable column 13. A positioning block 176 is fixedly connected to the side of the wedge block 175 away from the boss 173.

[0027] The boss 173 is slidably connected to the inside of the movable column 13. The mounting roller 11 and the positioning block 176 are provided with positioning grooves at corresponding positions. When the positioning block 176 is inserted into the slot 21, the rotating rod 14 is in a vertical state.

[0028] When the support plate 15 fixes the material cylinder 12 to the outside of the mounting roller 11, the boss 173 positions the positioning block 176 and the movable column 13 inside the positioning groove of the mounting roller 11, so that the rotating rod 14 pushes out the support plate 15 and locks it, so that the support plate 15 is rigidly fixed to the material cylinder 12, and its fixing effect is better.

[0029] Preferably, the outer side of the support plate 15 is arc-shaped and concentric with the material cylinder 12. The anti-slip pad 16 is disposed between the material cylinder 12 and the support plate 15. The support plate 15 is slidably connected to the inside of the mounting roller 11. The limiting block 171 is slidably connected to the inside of the mounting roller 11. The left end of the movable column 13 is fixedly connected to the operating panel.

[0030] It should be noted that the outer side of the support plate 15 is curved and concentric with the material cylinder 12, which makes the support plate 15 fit more closely with the inner wall of the material cylinder 12, further enhancing the installation effect. Secondly, the limiting block 171 limits the movable column 13 to prevent the movable column 13 from rotating inside the installation roller 11.

[0031] In use, the end of the material cylinder 12 away from the rewinder body 10 is sleeved onto the outside of the mounting roller 11. Then, the movable column 13 is pushed to the right and inserted into the mounting roller 11. At this time, the rotating rod 14 rotates, causing the support plate 15 to move away from the movable column 13. The three rotating rods 14 then unfold and abut against the inside of the material cylinder 12. The rotating column 172 is then rotated, causing the boss 173, threadedly connected to the outside of the rotating column 172, to move to the right. Initially, the tension spring 174 drives the inclined block 175 closer to the rotating column 172. At this time, the positioning block 176 is retracted inside the movable column 13 and does not affect the movement of the movable column 13. When the boss 173 moves to the right, the inclined surface of the inclined block 175 presses against the inclined surface of the inclined block 175, causing the inclined block 175 to drive the positioning block 176 to protrude from the inside of the movable column 13 and insert into the inside of the mounting roller 11, thereby deeply pressing the movable column 13 at the pushing position. The support plate 15 is fixed to the outside of the installation roller 11 to prevent the movable column 13 from moving inside the installation roller 11 during rotation, which would cause the support plate 15 to wobble and provide insufficient support for the material cylinder 12, affecting the stability of the material cylinder 12. Under the action of the support plate 15 and the anti-slip pad 16, the material cylinder 12 is firmly fixed to the outside of the installation roller 11. This allows the rewinding machine body 10 to drive the installation roller 11 to rotate the material cylinder 12 during operation, thereby allowing the material cylinder 12 to wind up the release film. The support plate 15 provides rigid support to fix the material cylinder 12, avoiding the problem of the material cylinder 12 falling off due to the influence of temperature, air pressure and the weight of the material outside the material cylinder 12. This ensures that the installation of the material cylinder 12 and the installation roller 11 is always stable and unaffected by external factors. Moreover, the support of the material cylinder 12 is quick and convenient, without the need to use an external air pump to inflate the installation roller 11, saving costs.

[0032] Example 2, refer to Figure 4 , Figure 6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a positioning component for a precision rewinding machine for release film processing based on embodiment 1. This solves the problem that the pressure on the support plate 15 is too high after the material outside the material cylinder 12 increases, and the rotating rod 14 is easily deformed by pressure, resulting in a decrease in the stability of the material cylinder 12 installation. It includes a positioning component, including a synchronous column 20, which is fixedly connected to the right end of the power assembly 17. The support plate 15 has a slot 21 inside. The synchronous column 20 is fixedly connected to the outside of the synchronous column 20. There are two turntables 22. Another turntable 22 is fixedly connected to the outside of the rotating column 172. Three inserts 23 are fixedly connected to the inner side of each of the two turntables 22. The inserts 23 are inserted into the inside of the slot 21. An arc-shaped groove is opened in the middle of the turntable 22.

[0033] Specifically, the arc-shaped groove is the rotation angle range of the turntable 22, and the insert block 23 is inserted into the slots 21 at both ends of the support plate 15 to reinforce the support plate 15 which is in a protruding state, making the installation of the material cylinder 12 more stable.

[0034] During use, when the movable column 13 is moved into position and the power assembly 17 fixes the position of the movable column 13, the rotating column 172 rotates, driving the synchronous column 20 to rotate, so that the two turntables 22 rotate synchronously, driving the insert block 23 to rotate. When the boss 173 pushes the positioning block 176 out of the movable column 13 and positions it inside the positioning groove of the mounting roller 11, when the synchronous column 20 and the rotating column 172 stop rotating, the insert block 23 is inserted into the slots 21 at both ends of the support plate 15, thereby reinforcing the support plate 15 protruding from the mounting roller 11. This prevents the support plate 15 from retracting into the mounting roller 11 when subjected to heavy pressure, thus improving the support effect on the material cylinder 12 and reducing the pressure on the rotating rod 14, preventing the rotating rod 14 from easily deforming, thereby extending the service life of the device.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
