Detailed implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0020] 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 term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0021] As Figures 1-3 shown, a limiting device for a graphene oxide coated substrate includes a bottom plate 1, and the bottom plate 1 has corresponding supporting force; a winding unit for winding the substrate is installed at one end, and a supporting table 2 is configured at the other end for laying out the unfolded substrate. The end of the supporting table 2 close to the winding unit is the feeding end; a supporting roller 3 is arranged on the front side of the feeding end for corresponding supporting operations; the winding unit is used to carry the wound substrate and can release the substrate through driving. A tensioning unit is arranged between the winding unit and the supporting table 2, and the tensioning unit can be set as one group or multiple groups according to the situation. Before the substrate is released into the supporting table 2, the substrate is tightened through the tensioning unit to avoid wrinkles when unfolding on the supporting table 2 and affecting the coating operation.

[0022] Among them, the winding unit includes two relative supporting members 15 arranged at one end of the bottom plate 1; a winding roller 16 rotatably installed between the supporting members 15; a rotary drive 17 rotatably installed outside the supporting members 15. One end of the winding roller 16 extends out of the supporting members 15 and is fixedly connected to the output end of the rotary drive 17, and the rotary drive 17 provides a rotary driving force to the winding roller 16. When releasing the substrate, the rotary drive 17 can be started, and the winding roller 16 rotates to release the substrate.

[0023] In some preferred embodiments, the tensioning unit is arranged on the bottom plate 1 and located between the winding unit and the support table 2. The tensioning unit includes a tensioning roller 13 erected on the bottom plate 1 through a telescopic column 12. The telescopic end of the telescopic column 12 is configured with a mounting block 14. The tensioning roller 13 is rotatably installed between the mounting blocks 14. On the substrate feeding path, the height of the tensioning roller 13 is adjusted through the telescopic column 12. The substrate passes below the tensioning roller 13 and contacts the tensioning roller 13 to straighten the substrate during feeding and avoid substrate wrinkles.

[0024] In some preferred embodiments, the feeding end of the support table 2 is configured with a synchronous limiting unit, including movable limiting units located on both sides of the substrate feeding direction and a front limiting unit connected to the movable limiting units. The front limiting unit is used to define the support operation width of the support roller 3.

[0025] Specifically, the feeding end of the support table 2 is configured with a mounting frame 4. The mounting frame 4 has two side plates located on both sides of the feeding direction. An activity groove 5 is recessed in the two side plates of the feeding end of the support table 2. The movable limiting unit includes a telescopic push rod 7 installed on the side plate of the mounting frame 4 and a limiting block 6 configured at the telescopic end of the telescopic push rod. A limiting operation surface is recessed on one side of the limiting block 6 away from the telescopic end. The feeding width of the substrate is defined between the two limiting operation surfaces. The front limiting unit includes a connecting rod 8. The connecting rod 8 is inserted into the front side of the limiting block 6 along the feeding direction. The connecting rod 8 is assembled with a limiting plate 9. The bottom of the limiting plate 9 is movably penetrated by the support roller 3. By adjusting the distance between the limiting blocks 6 through the telescopic push rod 7, the feeding width of the substrate is adaptively restricted. When the position between the limiting blocks 6 is adjusted, the limiting plate 9 moves with the limiting block 6, and the limiting plate 9 moves along the central axis direction of the support roller 3 to change the support operation width of the support roller 3. When the substrate is fed, after passing through the support roller 3, it is limited between the limiting blocks 6, which can effectively avoid feeding deviation.

[0026] It should be noted that a plug-in slot is assembled on the side wall of the limiting block 6. The plug-in slot is U-shaped and is adapted to the plug-in end of the connecting rod 8. The bottom of the limiting plate 9 is provided with a sliding slot for the support roller 3 to penetrate. The bottom of the sliding slot is open, so that the limiting plate 9 can be separated from the support roller 3 during plugging and unplugging. The number of sliding slots opened at the bottom of the limiting plate 9 corresponds to the support roller 3.

[0027] In some preferred embodiments, if necessary, cleaning brushes 10 can be assembled inside the limit plate 9. The two cleaning brushes 10 are arranged in a staggered manner, and the cleaning brushes 10 extend in a direction perpendicular to the feeding direction. A cleaning rod 11 is assembled on the working surface of the cleaning brush 10, and the cleaning rod 11 is used to clean the substrate passing through the supporting roller 3. The cleaning rod 11 is made of flexible rubber material to clean the surface of the substrate, remove dust and impurity particles on the surface, and avoid affecting the coating effect.

[0028] The specific use is as follows: Install the device in a suitable position. The substrate to be coated is wound on the winding roller 16. The distance between the two limit blocks 6 is adjusted adaptively according to the width of the substrate by the telescopic push rod 7. At the same time, the limit plate 9 moves with the corresponding limit block 6, and the distance between the limit plates 9 is adjusted adaptively. The limit plate 9 and the limit block 6 limit the width of the substrate feeding path to avoid feeding deviation. The limit blocks 6 are symmetrically arranged along the feeding direction, and the telescopic working distances of the two telescopic push rods 7 are the same. The substrate can pass under the tension roller 13, and the height of the tension roller 13 is adjusted by the telescopic column 12 to straighten the substrate and avoid wrinkles during feeding (in the prior art, the released end of the substrate can be wound and recycled after passing through the oven and separating from the formed graphene oxide film). In addition, when it is necessary to temporarily clean the coating surface of the substrate, the cleaning brushes 10 can be respectively assembled inside the limit plate 9 in a staggered manner, and the brush rods made of soft rubber material clean the surface of the substrate passing through the supporting roller 3.

[0029] 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 principle 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 design similar structural modes and embodiments without creative work without departing from the purpose of the present invention, 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 will not be elaborated in this application.
