Description

Technical Field

[0001] This utility model relates to the field of production fixture technology, specifically a production fixture for graphite release film sandwich rolls. Background Technology

[0002] In the production of artificial graphite, release film is a key auxiliary material. Its main function is to protect, isolate, and assist in the transfer of graphite materials during the preparation process, ensuring production efficiency and product quality. In traditional calendering processes, when graphite and release film are directly pressed together, the high viscosity of the release film leads to a mismatch, resulting in peeling residue and uneven graphite layer thickness, increasing the rate of appearance defects. This paper proposes a sandwich-film production method that protects graphite while solving the problem of graphite peeling residue. Therefore, a graphite release film sandwich roll is required. Production fixtures are needed when producing graphite release film sandwich rolls. In graphite preparation, the release film plays three main roles: protection: preventing the graphite layer from being scratched or contaminated by equipment during processing; isolation: preventing interlayer adhesion when multiple graphite layers are stacked, ensuring structural stability; and transfer: acting as a temporary carrier to assist in the peeling of graphite from the mold or substrate, improving operational efficiency.

[0003] Patent document CN209161495U discloses a production fixture for graphite film rolls, including a base plate and a top plate, with the top plate positioned parallel above the base plate. A winding drum is positioned between the base plate and the top plate, and at least one intermediate plate is positioned between the base plate and the top plate. The intermediate plate is fitted onto the winding drum and divides it into at least two independent PI film winding positions for winding PI film. A lower exhaust port for ventilation is provided on the base plate at a position corresponding to the lower end of the winding drum, an upper exhaust port for ventilation is provided on the top plate at a position corresponding to the upper end of the winding drum, and a middle exhaust port for ventilation is provided on the intermediate plate at a position corresponding to the middle of the winding drum. This utility model has high production efficiency, enabling mass production of graphite film rolls. It also allows for the rapid and complete extraction of large amounts of gas generated during the manufacturing process from the surface of the graphite film roll, improving the production quality of the graphite film roll.

[0004] However, the graphite film roll production fixture mentioned in the above-mentioned published documents mainly focuses on improving the production quality of graphite film rolls, and is not convenient for adjusting the spreading force of the inner shaft.

[0005] In view of this, it is necessary to develop a production fixture with a tension adjustment mechanism, so as to facilitate the adjustment of the opening force of the inner shaft. Utility Model Content

[0006] The purpose of this invention is to provide a production fixture for graphite release film sandwich rolls to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a production fixture for graphite release film sandwich roll material, comprising: a production support, an inner shaft, and a roll material tube. The inner shaft is provided on the inner wall of the production support, and the roll material tube is mounted around the outer wall of the inner shaft. A tension adjustment mechanism is provided on the outer wall of the inner shaft, and the tension adjustment mechanism is used to facilitate the adjustment of the spreading force of the inner shaft. The tension adjustment mechanism includes a mounting groove, a tension plate, and a tension block. The outer wall of the inner shaft is provided with a mounting groove, the inner wall of the mounting groove is fitted with a sleeve, the inner wall of the sleeve is movably fitted with a sleeve rod, the outer wall of the sleeve rod is surrounded by a spring, the outer wall of the sleeve rod is fitted with a tension plate, the top of the tension plate is fitted with a tension block, the outer wall of the tension block is inlaid with a bearing frame, the inner wall of the bearing frame is movably fitted with a rotating block, and the outer wall of the rotating block is fitted with a hemispherical contact block.

[0008] Preferably, the inner wall of the production support is provided with a disassembly mechanism, which is used to facilitate the disassembly of the inner shaft. The disassembly mechanism includes: a disassembly groove formed in the inner wall of the production support; a replacement groove provided in the outer wall of the inner shaft; a replacement post installed in the inner wall of the replacement groove; a locking stud installed in the outer wall of the replacement post; and a locking nut installed around the outer wall of the locking stud.

[0009] Preferably, the inner shaft is a cylinder with a diameter of 5 cm.

[0010] Preferably, the mounting groove is a square groove, and both the mounting groove and the sleeve are provided with six sets.

[0011] Preferably, the disassembly groove is a circular groove with a diameter of 8cm.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, by installing a tension adjustment mechanism, facilitates the adjustment of the spreading force of the inner shaft. Existing inner shafts can only support matching rolls of material. If the roll's internal size is too large, it causes the roll to sway up and down outside the inner shaft during rotation, making it impossible to limit rolls of different sizes. Therefore, this needs to be improved so that an inner shaft of one size can limit rolls of different sizes and adjust the tension. By manually pressing the tension plate, the sleeve retracts within the sleeve, compressing the spring and causing the tension plate to enter the interior of the roll. When the tension plate is released, the spring returns to its original position, allowing the hemispherical contact block on the outside of the tension block to come into contact with the inner wall of the roll. The degree of spring return depends on the size of the roll's interior, thus limiting the rolls of different sizes. When the roll rotates, the interior of the roll rubs against the hemispherical contact block, and the rotating block is movably connected in the bearing frame and can rotate. As the rotating block rotates in the bearing frame, the hemispherical contact block rotates with the roll, thus avoiding excessive friction between the roll and the hemispherical contact block when stationary. This facilitates the support of rolls of different sizes. 2. This utility model features a disassembly mechanism for easy disassembly of the inner shaft. Existing inner shafts are difficult to disassemble if damaged or during unloading, thus requiring improvement. First, the locking nut is rotated to remove the inner shaft from the outside of the locking stud through the thread. If the disassembly groove is small (a special case), the inner shaft is held by the outside, and the locking stud is rotated to remove the inner shaft from the disassembly groove through the thread, allowing for disassembly. However, in general, the disassembly groove is designed according to requirements, allowing the inner shaft to be pulled out directly through the disassembly groove by pressing the tension plate. The locking stud can also be disassembled, and when it wears out over a long period, it can be disassembled and replaced separately, reducing replacement costs and maximizing cost-effectiveness.

[0018] Please see Figure 1 , Figure 2 and Figure 5 A production fixture for graphite release film sandwich rolls includes: a production support 1, an inner shaft 2, and a roll 3. The inner shaft 2 is provided on the inner wall of the production support 1, and the roll 3 is mounted around the outer wall of the inner shaft 2. The film roll is surrounded by the outer side of the roll 3. When the graphite release film is produced, the production support 1 is mounted on the device, and the roll 3 is located outside the inner shaft 2 and is movably connected. The pulling force of the device causes the roll 3 to rotate outside the inner shaft 2, thereby conveying and feeding the film roll and producing the graphite release film sandwich roll.

[0019] Please see Figure 2 , Figure 3 and Figure 4 The inner shaft 2 has a tension adjustment mechanism on its outer wall. This mechanism facilitates adjustment of the opening force of the inner shaft 2. The tension adjustment mechanism includes a mounting groove 4, a tension plate 8, and a tension block 9. The inner shaft 2 has a mounting groove 4, and a sleeve 5 is installed on the inner wall of the mounting groove 4. A sleeve rod 6 is movably installed on the inner wall of the sleeve 5. A spring 7 is installed around the outer wall of the sleeve rod 6. A tension plate 8 is installed on the outer wall of the tension plate 8, and a tension block 9 is installed on the top of the tension plate 8. A bearing frame 10 is embedded in the outer wall of the tension block 9. A rotating block 11 is movably installed on the inner wall of the bearing frame 10, and a hemispherical contact block 12 is installed on the outer wall of the rotating block 11. The existing inner shaft 2 can only support the matching roll 3. If the roll 3 is too large, it will cause the roll 3 to sway up and down outside the inner shaft 2 during rotation (for example, the inner diameter of the roll 3 is 10cm, the diameter of the inner shaft 2 is 5cm, and the opening diameter of the tension plate 8 can reach 15cm), making it impossible to support different sizes. The roll 3 is limited, so it needs to be improved so that an inner shaft 2 of one size can limit rolls 3 of different sizes and adjust the tension. By manually pressing the tension plate 8, the sleeve 6 is retracted in the sleeve 5, the spring 7 is compressed, and the tension plate 8 enters the interior of the roll 3. At this time, the tension plate 8 is released, the spring 7 returns to its original position, so that the hemispherical contact block 12 on the outside of the tension block 9 comes into contact with the inner wall of the roll 3. The degree of return of the spring 7 is determined according to the size of the inside of the roll 3, thus completing the limitation of rolls 3 of different sizes. When the roll 3 is rotating, the inside of the roll 3 comes into contact with the hemispherical contact block 12 and rubs. The rotating block 11 is movably connected in the bearing frame 10 and can rotate. The rotating block 11 rotates in the bearing frame 10, and the hemispherical contact block 12 rotates with the rotation of the roll 3, thus avoiding the large friction between the roll 3 and the hemispherical contact block 12 when stationary, thus facilitating the support of rolls 3 of different sizes.

[0020] Please see Figure 1 and Figure 2The inner wall of the production support 1 is provided with a disassembly mechanism for facilitating the disassembly of the inner shaft 2. The disassembly mechanism includes a disassembly groove 13. The inner wall of the production support 1 is provided with a disassembly groove 13, and the outer wall of the inner shaft 2 is provided with a re-disassembly groove 14. A re-disassembly post 15 is installed on the inner wall of the re-disassembly post 14, and a locking stud 16 is installed on the outer wall of the re-disassembly post 15. A locking nut 17 is installed around the outer wall of the locking stud 16. The existing inner shaft 2 cannot be easily disassembled if damaged or unloaded, so this needs to be improved. First, rotate the locking nut 17 to remove it from the locking screw through the thread. After removing the outer part of the column 16, if the disassembly slot 13 is designed to be small (a special case), hold the outer part of the inner shaft 2 and then rotate the locking stud 16 so that the disassembly column 15 is removed from the disassembly slot 14 through the thread. At this time, the inner shaft 2 is disassembled. However, in general, the disassembly slot 13 is designed according to the requirements so that the inner shaft 2 can be directly pulled out through the disassembly slot 13 by pressing the tension plate 8. The locking stud 16 can also be disassembled. When the locking stud 16 is worn for a long time, it can be disassembled and replaced separately to reduce the replacement cost and improve the cost-effectiveness.

[0021] Working principle: A film roll is wrapped around the outside of the roll 3. During the production of graphite release film, the production support 1 is mounted on the device. The roll 3 is located outside the inner shaft 2 and is movably connected. The pulling force of the device causes the roll 3 to rotate outside the inner shaft 2, conveying and feeding the film roll to produce the graphite release film interlayer. The existing inner shaft 2 can only support the matching roll 3. If the inside of the roll 3 is too large, it will cause the roll 3 to sway up and down outside the inner shaft 2 during rotation, making it impossible to process different sizes of film. The roll 3 is used for limiting, so it needs to be improved so that an inner shaft 2 of one size can limit rolls 3 of different sizes and adjust the tension. By manually pressing the tension plate 8, the sleeve 6 is retracted in the sleeve 5, the spring 7 is compressed, and the tension plate 8 enters the interior of the roll 3. At this time, the tension plate 8 is released, the spring 7 returns to its original position, and the hemispherical contact block 12 on the outside of the tension block 9 comes into contact with the inner wall of the roll 3. The degree of return of the spring 7 is determined according to the size of the interior of the roll 3, thus completing the limiting of rolls 3 of different sizes. When the roll 3 rotates, the interior of the roll 3 comes into contact with and rubs against the hemispherical contact block 12. The rotating block 11 is movably connected within the bearing frame 10 and can rotate. As the rotating block 11 rotates within the bearing frame 10, the hemispherical contact block 12 rotates along with the roll 3, thus preventing excessive friction between the roll 3 and the hemispherical contact block 12 when stationary. This facilitates support for rolls 3 of different sizes. The existing inner shaft 2 is difficult to disassemble if damaged or if unloading is not convenient, so improvements are needed. First, the locking nut 17 is rotated to loosen the screw from the locking mechanism via threads. After removing the outer part of the locking stud 16, if the disassembly slot 13 is designed to be small (a special case), hold the outer part of the inner shaft 2 and then rotate the locking stud 16 so that the disassembly stud 15 is removed from the disassembly slot 14 through the thread. At this time, the inner shaft 2 is disassembled. However, in general, the disassembly slot 13 is designed according to the requirements so that the inner shaft 2 can be directly pulled out through the disassembly slot 13 by pressing the tension plate 8. The locking stud 16 can also be disassembled. When the locking stud 16 is worn for a long time, it can be disassembled and replaced separately to reduce the replacement cost and improve the cost-effectiveness.
