Abstract
Description
Technical Field
[0001] This utility model belongs to the field of polyimide film production technology, specifically a polyimide film production device. Background Technology
[0002] Polyimide possesses excellent thermal stability, chemical resistance, and mechanical properties. It is typically a transparent yellow color and is one of the most temperature-resistant polymers available. In addition, it has good mechanical properties and chemical stability, making it a highly promising flexible substrate material. It is particularly suitable as an insulating material for various high-temperature motors and electrical appliances.
[0003] Polyimide film production typically involves using take-up rollers to collect the film. After the film is finished being rolled up, it needs to be manually cut, and then the take-up roller is removed and replaced with a new one to continue collecting the film. Cutting the film also requires manual operation, which increases labor costs. Summary of the Invention
[0004] The purpose of this invention is to provide a polyimide film production apparatus that automatically breaks the film, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a polyimide film production device is provided, including a base, a guide frame fixedly connected to the left side of the top of the base, a fusing mechanism fixedly connected to the middle of the top of the base, a support device and a winding mechanism fixedly connected to the right side of the top of the base, a winding roller movably connected to the outer side of the winding mechanism, the fusing mechanism including a fixed frame fixedly connected to the middle of the top of the base, a second screw threadedly connected to the inside of the fixed frame, a lifting frame movably connected to the lower outer side of the second screw, a heating wire fixedly connected to the inner side of the lifting frame, and a lifting hole provided inside the fixed frame.
[0006] Optionally, the base includes a seat body, the interior of which is movably connected to a first screw, and the outer side of the first screw is threadedly connected to a sliding column.
[0007] Optionally, the support device includes a hydraulic telescopic rod fixedly connected to the top right side of the seat body, a placement plate fixedly connected to the top of the hydraulic telescopic rod, a rotating column movably connected to the inner side of the placement plate, and a roller movably connected to the outer side of the rotating column.
[0008] Optionally, the take-up roller includes a roller body movably connected to the outside of the take-up mechanism, and the roller body has an insertion hole inside.
[0009] Optionally, the winding mechanism includes a first support column fixedly connected to the top of the base and a second support column fixedly connected to the top of the slide column. A motor is fixedly connected to the front side of the first support column, and a rotating shaft is fixedly connected to the output end of the motor.
[0010] Optionally, the guide frame includes a fixed column fixedly connected to the top left side of the base body, a movable sleeve movably connected to the upper outer side of the fixed column, a bolt connected to the internal thread of the movable sleeve, a fixed shaft fixedly connected between the fixed column and the movable sleeve, and a rotating cylinder movably connected to the outer side of the fixed shaft.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This invention features a fusing mechanism that automatically disconnects the polyimide film. Simultaneously with winding, the heating wire is energized, causing its temperature to rise rapidly. An internal temperature controller within the mounting bracket maintains the heating wire's temperature between 300 and 350°C, ensuring it softens the polyimide film while preventing thermal degradation. Furthermore, the heating wire, made of a low-heat-capacity, fast-response nickel-chromium alloy wire with a diameter of 0.2 mm, is relatively thin, resulting in greater pressure on the polyimide film and facilitating rapid heating. The polyimide film is melted as it is continuously wound up. The thickness of the polyimide film on the outside of the winding roller increases, causing the polyimide film between the drum and the winding roller to rotate upwards. This rotation allows the polyimide film to come into contact with the heating wire, which melts the polyimide film and facilitates automatic disconnection. The height of the heating wire is adjusted according to the amount of winding on the winding roller, so that the heating wire can disconnect polyimide films on winding rollers with different winding amounts, while also ensuring that the winding amount on the same winding roller is equal.

[0024] Reference Figures 1 to 5 The present invention will now be described. The polyimide film production apparatus includes a base 1, a guide frame 6 fixedly connected to the left side of the top of the base 1, a fusing mechanism 5 fixedly connected to the middle of the top of the base 1, a support device 2 and a winding mechanism 4 fixedly connected to the right side of the top of the base 1, and a winding roller 3 movably connected to the outer side of the winding mechanism 4. The fusing mechanism 5 includes a fixed frame 501 fixedly connected to the middle of the top of the base 1. A temperature controller is installed inside the fixed frame 501 to control the temperature of the heating wire 505, ensuring that the temperature of the heating wire 505 is between 300 and 350°C, so that the heating wire 505 can both soften the polyimide film and prevent it from becoming brittle. The polyimide film undergoes thermal degradation. A second screw 504 is internally threaded onto the mounting bracket 501. A lifting bracket 503 is movably connected to the lower outer side of the second screw 504. The lifting bracket 503 can be raised and lowered through the lifting hole 502. A heating wire 505 is fixedly connected to the inner side of the lifting bracket 503. The heating wire 505 is made of a low-heat-capacity, fast-thermal-response nickel-chromium alloy wire with a diameter of 0.2mm, which is relatively thin. This allows the heating wire 505 to exert greater pressure on the polyimide film, easily and quickly melting it. The mounting bracket 501 has a lifting hole 502 inside. During use, the second screw 504 is turned to allow the lifting wire to move. The heating wire 505 can rotate inside the fixed frame 501, and its height can be raised and lowered inside the fixed frame 501 by the forward and reverse rotation of the second screw 504. This, in turn, drives the lifting frame 503 to adjust the height of the heating wire 505. After the heating wire 505 is adjusted to a suitable height, the polyimide film passes through the rotating drum 605 and is wound around the outside of the take-up roller 3. During winding, the polyimide film is positioned above the take-up roller 3. Then, by starting the motor 402, the take-up roller 3 is driven to wind the polyimide film, and at the same time, the heating wire 505 is energized, thereby increasing the temperature of the heating wire 505. As the polyimide film rapidly rises and continues to be wound up, the thickness of the polyimide film on the outside of the take-up roller 3 continuously increases. This causes the polyimide film between the rotary drum 605 and the take-up roller 3 to rotate upwards continuously. Through this rotation, the polyimide film can come into contact with the heating wire 505, which then melts the polyimide film under the high temperature of the heating wire 505. This facilitates the automatic disconnection of the polyimide film. Furthermore, the height of the heating wire 505 is adjusted according to the amount of winding on the take-up roller 3, so that the heating wire 505 can disconnect the polyimide film on the take-up roller 3 with different winding amounts, while also ensuring that the winding amount on the same take-up roller 3 is equal.
[0025] Furthermore, the base 1 includes a seat body 101, with a first screw 102 movably connected inside the seat body 101. A sliding column 103 is threadedly connected to the outer side of the first screw 102. The sliding column 103 can move inside the seat body 101. By rotating the first screw 102 and through the forward and reverse rotation of the first screw 102, the sliding column 103 can move back and forth inside the seat body 101, thereby driving the second support column 404 to move back and forth. By moving the second support column 404 backward, the second support column 404 can be removed from the rotating shaft 403, thereby allowing the take-up roller 3 to be removed from the rotating shaft 403. After removal, a new take-up roller 3 is inserted on the outer side of the rotating shaft 403. Then, by moving the second support column 404 forward, the rotating shaft 403 can be inserted into the interior of the second support column 404, allowing the rotating shaft 403 to rotate stably.
[0026] Furthermore, the support device 2 includes a hydraulic telescopic rod 201 fixedly connected to the top right side of the base 101. A placement tray 202 is fixedly connected to the top of the hydraulic telescopic rod 201. A rotating column 204 is movably connected to the inner side of the placement tray 202. The rotating column 204 can rotate inside the placement tray 202. A roller 203 is movably connected to the outer side of the rotating column 204. The roller 203 can rotate outside the rotating column 204. When it is necessary to remove the collected take-up roller 3, the placement tray 202 can be moved upward by activating the hydraulic telescopic rod 201, so that the roller 203 can contact the film wound on the take-up roller 3. Then, the second support column 404 is controlled to move back and forth to ensure that the take-up roller 3 can be completely removed from the outer side of the rotating shaft 403. When removing it, the take-up roller 3 can be pulled out more easily under the action of the rotating column 204 and the roller 203.
[0027] Furthermore, the take-up roller 3 includes a roller body 301 movably connected to the outside of the take-up mechanism 4. The roller body 301 has an insertion hole 302 inside, which is adapted to the rotating shaft 403 so that it can be inserted into the outside of the rotating shaft 403, and the rotating shaft 403 can drive the take-up roller 3 to rotate.
[0028] Furthermore, the winding mechanism 4 includes a first support column 401 fixedly connected to the top of the base 101 and a second support column 404 fixedly connected to the top of the slide column 103. The interior of the second support column 404 is provided with a slot for the rotating shaft 403 to be inserted, and the rotating shaft 403 can rotate inside the second support column 404 and the first support column 401. A motor 402 is fixedly connected to the front side of the first support column 401, and the output end of the motor 402 is fixedly connected to the rotating shaft 403. By starting the motor 402, the rotating shaft 403 can drive the winding roller 3 to rotate, thereby winding up the polyimide film wound on the winding roller 3.
[0029] Furthermore, the guide frame 6 includes a fixed column 601 fixedly connected to the top left side of the base 101. A movable sleeve 603 is movably connected to the upper outer side of the fixed column 601. The movable sleeve 603 can be raised and lowered outside the fixed column 601. A bolt 602 is threaded inside the movable sleeve 603. Fixed shafts 604 are fixedly connected between the fixed column 601 and the movable sleeve 603. A rotating drum 605 is movably connected to the outer side of the fixed shaft 604. The top of the lower rotating drum 605 is lower than the top of the take-up roller 3. The height is such that the polyimide film between the rotating drum 605 and the take-up roller 3 can rotate upwards during winding. The rotating drum 605 can rotate outside the fixed shaft 604. By loosening the bolt 602, the movable sleeve 603 can be raised and lowered outside the fixed column 601. By raising and lowering, the distance between the rotating drums 605 can be adjusted, which makes it easier to put the polyimide film between the rotating drums 605 and to press the polyimide film tightly, preventing the polyimide film from jumping and contacting the heating wire 505.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
