Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically a graphite rewinding tool. Background Technology

[0002] In the process of graphite rewinding, polyimide is used as raw material. The process involves carbonization, graphitization, graphite rewinding, and calendering to prepare thermal conductive and heat dissipation films. During the carbonization process, the gap variation or uneven shrinkage after PI rewinding can cause severe deformation in some areas. During the graphite rewinding process, cracks can easily occur, causing one roll to become multiple rolls, which affects the rewinding efficiency. In the calendering process, the addition of joints increases costs and affects efficiency.

[0003] Existing technology CN208843388U discloses a graphite rewinding machine, which includes: a machine body, a first motor, an unwinding shaft, an empty guide roller, a second motor, a take-up shaft, a main controller, a drive controller, and an operation panel. The first motor is installed at the beginning of the machine body, and the unwinding shaft is located at the beginning of the top of the machine body; the second motor is installed at the end of the machine body, and the take-up shaft is located at the end of the top of the machine body; the empty guide roller is located between the unwinding shaft and the take-up shaft; a positioning mechanism is located on one side of the take-up shaft; the operation panel is installed at the beginning of the machine body, and both the drive controller and the operation panel are electrically connected to the main controller; the first motor and the second motor are both electrically connected to the drive controller; a meter counter is installed on the empty guide roller, and the meter counter is electrically connected to the main controller. This utility model is not only simple in structure and easy to operate, but also has a meter counting function, automatically stops after the required length of winding is reached, and the positioning mechanism achieves positioning of both ends of the graphite during rewinding.

[0004] The above-mentioned technology does not have the function of secondary rewinding of graphite. The problem of poor quality of the roll material is easily caused by primary rewinding of graphite. In addition, there is only one diameter of winding bar when winding graphite, which cannot wind graphite on the outside of winding bars of different diameters. Therefore, a graphite rewinding fixture that can perform secondary rewinding of graphite and can wind graphite on the outside of winding bars of different diameters is needed to solve this problem. Utility Model Content

[0005] One objective of this application is to provide a graphite rewinding tool that can solve the technical problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a graphite rewinding fixture, comprising a plate, a motor 1 and a motor 2, wherein the motor 1 is installed at the bottom of the plate, a rotating rod 1 is installed at the output end of the motor 1, a rotating plate 1 is installed at one end of the rotating rod 1, and the rotating plate 1 is located above the plate, and a winding rod is installed at the top of the rotating plate 1. A second motor is installed at the bottom of the plate. A second rotating rod is installed at the output end of the second motor. A second rotating plate is installed at one end of the second rotating rod, and the second rotating plate is located above the plate. A prism is installed at the top of the second rotating plate, and a fixing mechanism is slidably provided on the outer side of the prism.

[0007] Preferably, the bottom of the plate is symmetrically equipped with support columns.

[0008] Preferably, a take-up tube is movably provided on the outer side of the prism.

[0009] Preferably, the fixing mechanism includes a sleeve, a frame, a bolt, a movable rod, and a friction rod. The sleeve is slidably installed on the outside of the prism. The frame is installed on the top of the sleeve and is located inside the take-up tube. The bolt is symmetrically installed through the top of the frame. Movable rods are movably installed through the inner walls of both sides of the frame. A friction rod is installed at one end of the movable rod and is located inside the take-up tube.

[0010] Preferably, an electric telescopic rod is symmetrically installed on the top of the plate, and a round rod is installed at the output end of the electric telescopic rod.

[0011] Preferably, a tube is movably mounted on the outer side of the round rod, and a soft silicone sleeve is mounted on the outer side of the tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The graphite sheet is wound once by the winding rod, and then the graphite sheet moves backward to the outside of the winding tube and is wound a second time. This allows the graphite roll to be corrected by the second winding when there are gaps between the graphite sheets during the first winding, thus improving the winding quality. By moving the movable rod outward, the friction rod can be moved outward, which can fix the friction rod to winding tubes of different diameters. This makes it easy for the graphite sheet to be wound a second time on the outside of winding tubes of different diameters.

[0013] 2. As the graphite sheet moves from the take-up bar to the outside of the take-up tube, the electric telescopic rod drives the round rod to move towards the graphite sheet, causing the soft silicone sleeve to contact the graphite sheet. Then, the soft silicone sleeve and the tube rotate as the graphite sheet moves, thereby removing impurities from the surface of the graphite sheet. This reduces the gaps caused by impurities on the graphite sheet after it is taken up. Furthermore, when a part of the outer area of ​​the soft silicone sleeve is contaminated, rotating the tube allows the other uncontaminated part of the soft silicone sleeve to contact the graphite sheet for cleaning, reducing the frequency of removing and cleaning the soft silicone sleeve.

The plate 1 provides mounting positions for other components of the equipment. The support columns 101 support the plate 1. The motor 2 drives the rotating rod 201 to rotate, which in turn drives the rotating plate 202 to rotate. The rotation of the rotating plate 202 drives the winding rod 203 to rotate, thereby causing the winding rod 203 to wind up the graphite sheet. The rotating plate 202 provides support for the graphite roll.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a graphite rewinding fixture, comprising a second motor 3 and a fixing mechanism. The second motor 3 is mounted on the bottom of the plate 1. A rotating rod 301 is mounted on the output end of the second motor 3. A rotating plate 302 is mounted on one end of the rotating rod 301, and the rotating plate 302 is located above the plate 1. A prism 303 is mounted on the top of the rotating plate 302. A take-up tube 403 is movably arranged on the outer side of the prism 303. A fixing mechanism is slidably arranged on the outer side of the prism 303. The fixing mechanism includes a sleeve 4, a frame 401, a bolt 402, a movable rod 5, and a friction rod 501. The sleeve 4 is slidably mounted on the outer side of the prism 303.

Movable rods 5 are movably installed through the inner walls on both sides. A friction rod 501 is installed at one end of the movable rod 5, and the friction rod 501 is located inside the take-up tube 403. The motor 2 3 can drive the rotating rod 2 301 to rotate, which in turn drives the rotating plate 2 302 to rotate, thereby driving the prism 303 to rotate, and further driving the take-up tube 403 to rotate, so that the take-up tube 403 can rewind the graphite sheet. The sleeve 4 can only move up and down on the outside of the prism 303, so that the sleeve 4 can be easily removed from the outside of the prism 303.

The movable rod 5 can drive the friction rod 501 to move outward by moving outward, so that the friction rod 501 contacts the inner wall of the take-up tube 403 outward, so that the friction rod 501 can drive the take-up tube 403 to rotate by friction when the prism 303 rotates.

[0021] Please see Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a graphite rewinding fixture, comprising an electric telescopic rod 6. The electric telescopic rod 6 is symmetrically mounted on the top of the plate 1. A round rod 601 is mounted at the output end of the electric telescopic rod 6. A tube 602 is movably mounted on the outer side of the round rod 601. A soft silicone sleeve 603 is mounted on the outer side of the tube 602. The electric telescopic rod 6 can drive the round rod 601 to move left and right, thereby driving the tube 602 to move left and right, so that the soft silicone sleeve 603 on the outer side of the tube 602 can contact the outer side of the graphite sheet. Then, the soft silicone sleeve 603 and the tube 602 rotate as the graphite sheet moves, thereby removing impurities from the surface of the graphite sheet.

[0022] Working principle: Before using the graphite rewinding fixture, it should be checked whether there are any problems that may affect its use. First, the graphite sheet is wound once by the winding rod 203. Then, the graphite sheet moves backward to the outside of the winding tube 403 and is wound a second time by the winding tube 403. During the process of the graphite sheet moving from the winding rod 203 to the outside of the winding tube 403, the electric telescopic rod 6 drives the round rod 601 to move towards the graphite sheet, so that the soft silicone sleeve 603 contacts the graphite sheet. Then, the soft silicone sleeve 603 and the tube body 602 rotate with the movement of the graphite sheet, so that the soft silicone sleeve 603 removes impurities from the surface of the graphite sheet. By moving the movable rod 5 outward, the friction rod 501 can be moved outward, which can fix the friction rod 501 to the winding tube 403 of different diameters, so that the graphite sheet can be easily wound a second time to the outside of the winding tube 403 of different diameters.
