[0002] For the large-scale preparation of graphene heat dissipation films, graphene oxide is generally used as a precursor.

Graphene heat dissipation films with different width specifications are likely to cause uneven edges of the wound material during winding. In addition, when the graphene heat dissipation film is fed during winding, the heat dissipation film cannot be smoothed out, easily resulting in winding wrinkles. Summary of the Utility Model

[0010] After adopting the above structure, the beneficial effects of the utility model are as follows: the utility model proposes a graphene heat dissipation film adjustment and winding device, which adjusts the winding width of the winding roller according to the width of the wound graphene heat dissipation film under the drive of the push drive through the arranged movable disk, and is limited on both sides with the fixed disk to avoid uneven edges when the material is rolled up due to skewed feeding; through the arranged limiting roller and supported by the adaptive supporting unit, it is stretched out by the heat dissipation film passing by during rolling, and the heat dissipation film passing by can be smoothed, and the rolled graphene heat dissipation film is limited and supported at the bottom, making the rolling more convenient and neat.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0018] As Figures 1 - 3 shown, a graphene heat dissipation film adjusting and winding device includes a support table 1 and a winding roller 2 mounted on the support table 1. The support table 1 has corresponding supporting force, and fixed side plates 5 are respectively arranged at both ends in the length direction; the winding roller 2 has a predetermined winding width, is mounted above the support table 1, is connected to a rotation drive 6, and performs corresponding winding operations. Here, preferably, the winding roller 2 is mounted above the support table 1 through two opposite mounting plates 12. The winding roller 2 is rotatably mounted between the two mounting plates 12. One end of the winding roller 2 is connected to the rotation drive 6, and the output end of the rotation drive 6 is fixedly connected to the corresponding end of the winding roller 2 to provide a rotation driving force to the winding roller 2. When the winding roller 2 rotates, it can perform the winding operation of the graphene heat dissipation film;

[0019] In some preferred embodiments, a pushing drive is assembled between the mounting plate 12 and the fixed side plate 5 at the same end. The pushing drive can be a telescopic push rod 7. The telescopic end of the telescopic push rod 7 movably penetrates through the corresponding mounting plate 12 and is assembled with a movable disk 3. The movable disk 3 moves along the central axis direction of the winding roller 2, and can limit the winding width of the winding roller 2. Further, a fixed disk 13 is fixedly assembled inside the mounting plate 12.

[0020] Specifically, the corresponding end of the winding roller 2 movably penetrates through the fixed disk 13, and a through groove for the limiting roller 4 to movably penetrate is opened below the fixed disk 13; specifically, the movable disk 3 is sleeved outside the winding roller 2, and a through groove for the limiting roller 4 to movably penetrate is opened below; when the winding roller 2 rotates, the movable disk 3 does not interfere with the winding roller 2. Before the winding operation, according to the width of the heat dissipation film to be wound, the position of the movable disk 3 is adjusted, and the heat dissipation film can be wound between the fixed disk 13 and the movable disk 3 to avoid uneven edges when forming a roll.

[0021] In some preferred embodiments, a limiting roller 4 is arranged below the supporting roller. The limiting roller 4 is mounted above the support table 1 through an adaptive supporting unit and is located below the winding roller 2.

[0022] Specifically, the adaptive support unit includes movable blocks 8 configured at both ends of the limit roller 4. The limit roller 4 is laterally rotatably connected to the movable blocks 8. A limit upper plate 9 is fixed inside the fixed side plate 5 and above the movable blocks 8. A limit vertical rod 10 is fixed between the limit upper plate 9 and the top of the support table 1, and the limit vertical plate movably penetrates through the movable blocks 8. A support spring 11 with corresponding elastic support force is arranged between the movable blocks 8 and the top of the support table 1 and wound around the limit vertical rod 10. During winding, first, one end of the heat dissipation film to be wound is passed through between the limit roller 4 and the winding roller 2. At this time, the limit roller 4 is pushed open by the heat dissipation film and downwardly presses the support spring 11. The support spring 11 applies a reverse support force to the movable blocks 8, causing the limit roller 4 to abut against the outside of the heat dissipation film. During winding, the heat dissipation film passes between the limit roller 4 and the winding roller 2 and is squeezed and smoothed, avoiding wrinkles during winding and making the winding more convenient and neater.

[0023] The specific use is as follows: Place the device at a suitable working position; adjust the position of the movable disk 3 according to the width of the heat dissipation film to be wound first, and adjust the winding width of the winding roller 2; pass one end of the heat dissipation film to be wound through between the limit roller 4 and the winding roller 2; start the rotary drive 6, and the winding roller 2 rotates to perform the winding operation of the heat dissipation film. During winding, the limit roller 4 is pushed open by the heat dissipation film and presses down the movable blocks 8. The movable blocks 8 squeeze the support spring 11, and the support spring 11 applies a reverse acting force to the movable blocks 8 and the limit roller 4, causing the limit roller 4 to lift. It can be realized that when winding the heat dissipation film, the heat dissipation film passes between the limit roller 4 and the winding roller 2 and is smoothed, making the winding more convenient and neater.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the present invention's creation, design similar structural methods and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the present invention. Each component of this application can be driven by a corresponding external motor, which is prior art and not elaborated in this application.
