Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of graphite film production equipment, and in particular to a graphite film winding device. Background Technology
[0002] The large-scale preparation of graphene heat dissipation films generally uses graphene oxide as a precursor. After forming a uniformly distributed GO aqueous solution through ultrasonic dispersion, graphene oxide films are prepared by vacuum filtration, wet spinning, evaporation, and blade coating. Then, a reducing agent is used to reduce the graphene oxide film to obtain the final product.
[0003] For example, the graphene heat dissipation film adjustment and winding device disclosed in application number CN202422315312.3 belongs to the technical field of graphene heat dissipation film production related equipment. It includes a support platform, a winding roller, a movable disc, and a limiting roller. The support platform has corresponding support force, and fixed side plates are respectively configured at both ends in the length direction. The winding roller has a predetermined winding width, is mounted above the support platform, and is connected to a rotation drive to perform corresponding winding operations. The movable disc is connected to a push drive and moves along the central axis of the winding roller, which can limit the winding width of the winding roller. The limiting roller is mounted above the support platform and below the winding roller through an adaptive support unit, which facilitates adaptive adjustment of the winding width and can smooth the heat dissipation film during winding, making the winding operation convenient and neat.
[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problems of uneven material edges caused by the fixed winding width of the winding roller when winding graphene heat dissipation films of different widths, and the inability to smooth the heat dissipation film during winding feeding, which easily leads to winding wrinkles, it does not have a cleaning structure. This results in dust or impurities adhering to the surface of the film during collection, causing the film to roll up the dust or impurities inside. Utility Model Content

[0027] Example 1
[0028] Reference Figures 1-3 In the first embodiment of this utility model, a graphite film winding device is provided, which uses a dust suction mechanism 200 to clean dust from the film.
[0029] The collection mechanism 100 includes a mounting frame 101, a take-up roller 102 is movably mounted inside the mounting frame 101, an adjusting plate 103 is movably connected to the surface of the take-up roller 102, and an electric telescopic rod 104 is fixedly mounted on the outside of the adjusting plate 103. The electric telescopic rod 104 is fixedly mounted on the top right side of the mounting frame 101.
[0030] The vacuuming mechanism 200 includes a fixed frame 201, which is fixedly connected to the right side of the mounting frame 101. Support rollers 202 are movably connected to both sides inside the fixed frame 201. A vacuuming ring tube 203 is fixedly installed inside the fixed frame 201. A vacuuming port 204 is fixedly connected to the top and bottom of the inner side of the vacuuming ring tube 203. A vacuuming box 205 is fixedly connected to the bottom of the vacuuming ring tube 203. A suction assembly 206 is fixedly installed on both sides of the bottom inside the vacuuming box 205.
[0031] The exhaust assembly 206 includes a connecting frame 206a, a motor 206b is fixedly connected inside the connecting frame 206a, an exhaust fan 206c is fixedly connected to the output end of the motor 206b, and exhaust vents 206d are provided on both sides of the bottom of the dust collection box 205.
[0032] Protective grilles 207 are fixedly connected to both sides of the bottom of the dust collection box 205.
[0033] Specifically, when the motor 206b on the connecting frame 206a in the exhaust assembly 206 is started, it drives the exhaust fan 206c to rotate. The rotation of the exhaust fan 206c can exhaust the air inside the suction ring tube 203 through the exhaust port 206d, thereby creating suction at the suction port 204 on the suction ring tube 203. This suction can draw dust on the film into the suction ring tube 203 through the suction port 204.
[0034] The use of protective grille 207 can seal the exhaust vent 206d, thereby preventing the exhaust fan 206c from being hit by foreign objects.
[0035] Furthermore, when the film is being wound up, the motor 206b inside the connecting frame 206a is activated. After the motor 206b is started, it drives the exhaust fan 206c to rotate. After the exhaust fan 206c rotates, it can exhaust the air inside the dust collection box 205 through the exhaust port 206d, so that the inside of the dust collection box 205 is in a negative pressure state. At this time, the suction port 204 on the dust collection ring tube 203 connected to the dust collection box 205 will generate suction, so that when the film passes through the dust collection ring tube 203, the surface dust will be sucked into the dust collection ring tube 203 and then into the dust collection box 205.
[0036] Example 2
[0037] Reference Figures 1-3 In a second embodiment of this utility model, a graphite film winding device is provided, which filters dust through a filter mechanism 300.
[0038] The filter mechanism 300 includes a filter screen 301, which is movably installed inside the dust collection box 205. Each of the four corners of the bottom of the inner wall of the dust collection box 205 is fixedly connected to a clamping component 302, and the bottom of the filter screen 301 is fixedly connected to an installation component 303.
[0039] The clamping assembly 302 includes a spring 302a, and a clamping plate 302b is provided inside the dust collection box 205. The top of the spring 302a is fixedly connected to the bottom of the clamping plate 302b.
[0040] Mounting assembly 303 includes mounting strip 303a, mounting base 303b is fixedly connected to the top of the abutment plate 302b, and mounting strip 303a is movably connected to mounting base 303b.
[0041] A telescopic protective sleeve 304 is fitted onto the surface of the spring 302a. The top of the telescopic protective sleeve 304 is fixedly connected to the bottom of the abutment plate 302b, and the bottom of the telescopic protective sleeve 304 is fixedly connected to the bottom of the inner wall of the dust collection box 205.
[0042] Limiting blocks 305 are fixedly connected to both sides of the rear side of the clamping plate 302b, and limiting grooves 306 are opened on both sides of the rear side of the inner wall of the dust collection box 205. The limiting blocks 305 and the limiting grooves 306 are movably connected.
[0043] Specifically, the spring 302a inside the clamping assembly 302 can drive the clamping plate 302b to move upward through its own elasticity. After the clamping plate 302b moves upward, it can drive the filter screen 301 to move upward, so that the filter screen 301 can fit into the dust collection box 205.
[0044] The installation strip 303a inside the mounting component 303 can be easily inserted into the mounting base 303b to install the filter screen 301, and at the same time, it can be easily disassembled and cleaned by the user.
[0045] The use of the telescopic protective sleeve 304 can protect the surface of the spring 302a, thereby extending the service life of the spring 302a.
[0046] When the abutment plate 302b moves, it will drive the limiting block 305 to move inside the limiting groove 306. Thus, the cooperation between the limiting block 305 and the limiting groove 306 can limit the abutment plate 302b, making the abutment plate 302b more stable when moving up and down.
[0047] Furthermore, when dust-laden air enters the dust collection box 205, it is filtered by the filter screen 301. When the filter screen 301 needs to be replaced and cleaned after long-term use, press down on the retaining plate 302b to compress the spring 302a, thereby releasing the pressure on the filter screen 301. Then, the user pulls the filter screen 301, causing the filter screen 301 to move the mounting strip 303a forward inside the mounting base 303b, thus completing the replacement of the filter screen 301.
[0048] It should be noted that filter 301 is V-shaped.
[0049] The remaining structure is the same as that in Example 2.
[0050] Example 3
[0051] Reference Figures 1-3 This is the third embodiment of the present invention, which differs from the second embodiment in that it is a graphite film winding device.
[0052] When the film is being wound up, the motor 206b inside the connecting frame 206a is activated. After the motor 206b starts, it drives the exhaust fan 206c to rotate. After the exhaust fan 206c rotates, it can exhaust the air inside the dust collection box 205 through the exhaust port 206d, so that the inside of the dust collection box 205 is in a negative pressure state. At this time, the suction port 204 on the dust collection ring tube 203 connected to the dust collection box 205 will generate suction force, so that when the film passes through the dust collection ring tube 203, the surface dust will be sucked into the dust collection ring tube 203 and then into the dust collection box 205.
[0053] When dust-laden air enters the dust collection box 205, it is filtered by the filter screen 301. When the filter screen 301 needs to be replaced and cleaned after long-term use, press down on the retaining plate 302b to compress the spring 302a, thereby releasing the pressure on the filter screen 301. Then, the user pulls the filter screen 301, causing the filter screen 301 to move the mounting strip 303a forward inside the mounting base 303b, thus completing the replacement of the filter screen 301.
[0054] In summary, the dust on the membrane surface is cleaned by the suction mechanism 200 sucking the dust into the suction box 205, while the filter mechanism 300 filters the dust sucked into the suction box 205 to prevent the dust from causing secondary pollution to the membrane.
