[0002] Thermally conductive carbon film is a new type of material with carbon as its main component and high thermal conductivity, which is widely used in many fields.

[0003] During the production and processing of thermally conductive carbon film, operators use a winding device to wind the film, facilitating subsequent processing such as slitting and die-cutting. However, some winding devices can only wind thermally conductive carbon film of a fixed size. When producing thermally conductive carbon film of different specifications, the winding device cannot be used, and operators need to purchase a matching winding device to continue using it. This is cumbersome and costly, causing inconvenience to the production of thermally conductive carbon film.

[0004] Therefore, this utility model provides a winding device for producing thermally conductive carbon film to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a winding device for the production of thermally conductive carbon film, which aims to solve the problem that some existing winding devices can only wind up thermally conductive carbon films of a fixed size. When it is necessary to produce thermally conductive carbon films of different widths, the winding device cannot be adapted for use, and the operator has to purchase a matching winding device to continue using it. This is more troublesome to operate and more costly, thus causing inconvenience to the production of thermally conductive carbon films.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding device for producing thermally conductive carbon film, comprising a base, universal wheels connected to the bottom surface at the four corners of the base, and uprights symmetrically connected to the top surface of the base, a first bearing embedded in the side surface of the upright facing the base, a rotating shaft being connected through the first bearing, one end of the rotating shaft passing through the upright and fixedly connected to the output end of a reduction motor, the reduction motor being connected to one side surface at the top of the upright, a winding roller being connected between the two rotating shafts, sliders symmetrically connected to the bottom surface of the upright, one end of the slider extending into a groove, the groove being symmetrically opened on the top surface of the base, movable blocks connected to the bottom surface of the slider, a movable groove being opened at the middle position of the bottom surface of the base, and movable blocks being connected to the inner surfaces at both ends of the movable groove.

[0007] As a preferred embodiment of the rewinding device for producing thermally conductive carbon film according to this utility model, the two sides of the rewinding roller are connected with connecting blocks, one end of the connecting block extends into the connecting groove, and the connecting groove is opened on the top surface of one end of the rotating shaft.

[0008] As a preferred embodiment of the winding device for producing thermally conductive carbon film according to this utility model, a butterfly bolt is connected through the front end surface of the rotating shaft. One end of the butterfly bolt passes through the interior of the limiting hole, which is opened through the front end surface of the connecting block. The butterfly bolt forms a threaded connection with the rotating shaft through the limiting hole.

[0009] As a preferred embodiment of the winding device for producing thermally conductive carbon film according to this utility model, the inner two sides of the movable groove are provided with second bearings, and a bidirectional screw is connected between the two second bearings. Movable blocks are threaded through both ends of the bidirectional screw, and one end of the bidirectional screw extends into the base and is fixedly connected to the output end of the drive motor.

[0010] As a preferred embodiment of the winding device for producing thermally conductive carbon film according to this utility model, the top surface of the four corners of the base is provided with mounting grooves, the bottom surface of the inner side of the mounting groove is connected to an electric push rod, the movable end of the electric push rod passes through the base and is connected to the top surface of the moving plate, and the bottom surface of the moving plate is connected to an anti-slip pad.

[0011] In a preferred embodiment of the thermally conductive carbon film production winding device of this utility model, the geared motor, drive motor, and electric push rod are electrically connected to an external power supply via a control switch.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a drive motor to rotate a bidirectional screw, causing a movable block on the screw to move along a movable groove. This, in turn, moves a slider on the movable block, moving the uprights and altering the distance between them. This adjustment allows for the installation of different sized winding rollers, enabling the winding of thermally conductive carbon films of various specifications. This eliminates the need for operators to purchase a complete winding device, reducing operating costs and simplifying the production process of thermally conductive carbon films.

[0014] This invention utilizes the cooperation of an electric push rod, a movable plate, and an anti-slip pad. When the winding device is in use, the electric push rod can be activated, causing its movable end to push the movable plate to move, making the anti-slip pad at the bottom of the movable plate contact the ground, thereby increasing the friction between the device and the ground and improving the stability of the winding device during use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a winding device for producing thermally conductive carbon film, comprising a base 1, universal wheels 2 connected to the bottom surface of the four corners of the base 1, and uprights 3 symmetrically connected to the top surface of the base 1, a first bearing 4 embedded in the side surface of the uprights 3 facing the base 1, a rotating shaft 5 passing through the first bearing 4, one end of the rotating shaft 5 passing through the uprights 3 and fixedly connected to the output end of a reduction motor 6, the reduction motor 6 being connected to one side surface at the top of the uprights 3, a winding roller 7 connected between the two rotating shafts 5, sliders 12 symmetrically connected to the bottom surface of the uprights 3, one end of the sliders 12 extending into a groove 13, the grooves 13 being symmetrically opened on the top surface of the base 1, movable blocks 18 connected to the bottom surface of the sliders 12, a movable groove 14 being opened at the middle position of the bottom surface of the base 1, and movable blocks 18 being connected to the inner surfaces at both ends of the movable groove 14.

[0023] Preferably, connecting blocks 8 are connected to both sides of the winding roller 7, one end of the connecting block 8 extends into the connecting groove 9, and the connecting groove 9 is opened on the top surface of one end of the rotating shaft 5.

[0024] In practical use, the take-up roller 7 can be customized to be processed into different sizes for use. The connecting blocks 8 on both sides of the take-up roller 7 can be slidably placed into the connecting grooves 9 on the rotating shaft 5. The take-up roller 7 can be placed or separated between the two rotating shafts 5 through the connecting blocks 8.

[0025] Preferably, a butterfly bolt 10 is connected through the front end surface of the rotating shaft 5. One end of the butterfly bolt 10 passes through the interior of the limiting hole 11. The limiting hole 11 is opened through the front end surface of the connecting block 8. The butterfly bolt 10 forms a threaded connection with the rotating shaft 5 through the limiting hole 11.

[0026] In practical use, when the connecting block 8 on the take-up roller 7 is slidably placed into the connecting groove 9 on the rotating shaft 5, the butterfly bolt 10 is screwed into the rotating shaft 5 through the limiting hole 11, which fixes the position of the connecting block 8 in the connecting groove 9, connecting the rotating shaft 5 and the take-up roller 7 together. At this time, the rotating shaft 5 can drive the take-up roller 7 to rotate. By unscrewing the butterfly bolt 10, the connecting block 8 can be separated from the limiting hole 11, allowing the connecting block 8 to move out of the connecting groove 9, so that the take-up roller 7 can be disassembled, allowing the operator to install the next take-up roller 7 for use.

[0027] Preferably, the inner two sides of the movable groove 14 are fitted with second bearings 15, and a bidirectional screw 16 is connected between the two second bearings 15. The two ends of the bidirectional screw 16 are threadedly connected to movable blocks 18, and one end of the bidirectional screw 16 extends into the base 1 and is fixedly connected to the output end of the drive motor 17.

[0028] In practical use, the drive motor 17 is connected to one side surface of the base 1. By starting the drive motor 17, the output end of the drive motor 17 can drive the bidirectional screw 16 to rotate in the second bearing 15, so that the bidirectional screw 16 can move the movable block 18 in the movable groove 14. At this time, the movable block 18 will move the slider 12 in the sliding groove 13.

[0029] Preferably, the base 1 has mounting grooves 19 on the top surface at the four corners, and an electric push rod 20 is connected to the bottom surface of the inner side of the mounting groove 19. The movable end of the electric push rod 20 passes through the base 1 and is connected to the top surface of the movable plate 21. An anti-slip pad 22 is connected to the bottom surface of the movable plate 21.

[0030] In practical use, by activating the electric push rod 20, the movable end of the electric push rod 20 can drive the anti-slip pad 22 at the bottom of the moving plate 21 to move, allowing the anti-slip pad 22 to contact or separate from the ground. When the anti-slip pad 22 contacts the ground, it can increase the friction between the anti-slip pad and the ground. When the anti-slip pad 22 separates from the ground, the winding device can be moved normally by the universal wheels 2. The anti-slip pad 22 is made of rubber.

[0031] Preferably, the geared motor 6, the drive motor 17, and the electric push rod 20 are electrically connected to an external power source via a control switch.

[0032] In practical use, the geared motor 6, drive motor 17, and electric push rod 20 can be controlled by a control switch. The four electric push rods 20 are connected in parallel to one control switch, allowing the operator to control all four electric push rods 20 simultaneously through one control switch, ensuring the synchronicity of the operation of the four electric push rods 20.

[0033] Working principle: When using the winding device for thermally conductive carbon film production, the winding device is moved to the designated position in the thermally conductive carbon film production scene using the universal wheels 2. Then, the brakes on the universal wheels 2 are applied to fix their position. Next, the electric push rod 20 is activated, causing its movable end to push the moving plate 21 downwards, making the anti-slip pad 22 at the bottom of the moving plate 21 contact the ground, thereby increasing friction and improving the stability of the winding device. Then, a winding roller 7 of matching size is selected according to the size of the thermally conductive carbon film to be wound. The distance between the two uprights 3 is adjusted according to the size of the winding roller 7. The drive motor 17 is activated, causing its output to drive the bidirectional screw 16 to rotate in the second bearing 15. The movable block 18 on the bidirectional screw 16 moves along the movable groove 14 on the base 1. The movable block 18 then moves the slider 12 along the slide groove 13, allowing the slider 12 to move along the uprights 3. The base 1 is moved to change the distance between the two uprights 3. After the uprights 3 are moved to the appropriate position, the connecting blocks 8 at both ends of the take-up roller 7 are slid into the connecting grooves 9 on the rotating shaft 5. Then, the butterfly bolts 10 are screwed into the rotating shaft 5 through the limiting holes 11 on the connecting blocks 8, thus fixing the position of the connecting blocks 8 inside the rotating shaft 5 and connecting the rotating shaft 5 with the take-up roller 7. At this time, one end of the thermally conductive carbon film is attached to the take-up roller 7 with tape. Then, the reduction motor 6 is started, which can drive the rotating shaft 5 to rotate in the first bearing 4, so that the rotating shaft 5 can drive the take-up roller 7 to rotate. At this time, the take-up roller 7 can perform the take-up operation of the thermally conductive carbon film. With this setting, the operator only needs to purchase the take-up roller 7 of the appropriate size and adjust the position of the uprights 3 to make the take-up device adaptable to thermally conductive carbon films of different specifications, thereby improving the adaptability of the take-up device, preventing the operator from purchasing the entire take-up device, thereby reducing the cost of use and bringing convenience to the production operation of thermally conductive carbon film.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
