At present, the development trend of the graphene electric heating film industry is to move forward in the direction of flexible electric heating films, especially in the field of heated clothing. Clothing companies have extremely high requirements for the flexibility of graphene electric heating films.

They must not produce any abnormal noise during bending, rubbing and normal use, and the number of machine washings must reach at least 40 times. Moreover, in this field, graphene electric heating films are also expected to be able to repeatedly deform or stretch with the clothing fabric under the action of external forces, so as to provide consumers with a more superior integrated experience and eliminate the foreign body feeling and independent existence of electric heating films in clothing.

[0034] The utility model is described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-4 As shown, a printing mechanism of a printed graphene thermal conductive film device comprises a longitudinally arranged longitudinal linear module 11, a transversely arranged transverse linear module 12 is installed at the driving end of the longitudinal linear module 11, and a lifting drive seat 1 is installed at the driving end of the transverse linear module 12, so that the lifting drive seat 1 can move longitudinally and transversely, that is, the lifting drive seat 1 can move in the X and Z axis directions.

[0036] A film conveying mechanism 13 for advancing the film is arranged below the lifting drive seat 1. The film conveying mechanism 13 includes a pair of belt conveyors 14 arranged in parallel and spaced apart, and a positioning plate 15 for supporting the film is installed between the two belt conveyors 14; the film to be printed is attached to the positioning plate 15, and the channel positioning plate 15 hard supports the film, and then it is moved to the bottom of the lifting drive seat 1 under the conveyance of the belt conveyors 14 to be printed.

[0037] The horizontal linear module 12 is also equipped with a pressing and positioning mechanism 2, which includes a pressing guide plate 21, and the pressing guide plate 21 is equipped with a pressing frame 22 that can move longitudinally, and the pressing frame 22 is equipped with a pressing strip 23 that can move longitudinally; when the positioning plate 15 with the film attached moves to the bottom of the lifting drive seat 1, the pressing guide plate 21 descends and approaches the positioning plate 15, and then the pressing strip 23 continues to press down to press the edge of the film to prevent the film from shifting laterally during printing, thereby ensuring the quality of printing.

[0038] Preferably, the pressing guide plates 21 are respectively installed at both ends of the horizontal linear module 12, and the pressing frame 22 is arranged between the two pressing guide plates 21. The pressing guide plates 21 are installed with a longitudinally arranged first pressing lifting cylinder 24, and the first pressing lifting cylinder 24 can drive the pressing frame 22 to move longitudinally; under the lifting drive of the first pressing lifting cylinder 24, the pressing frame 22 located between the two pressing guide plates 21 can move in the vertical direction, and the pressing frame 22 can be close to or away from the positioning plate 15.

[0039] Preferably, a pressing guide hole 25 is longitudinally opened on the pressing guide plate 21, and a pressing guide rod 26 is slidably installed in the pressing guide hole 25. A pressing connecting plate 16 is installed on the top of the pressing guide rod 26, and the bottom of the pressing guide rod 26 is connected to the pressing frame 22. The first pressing lifting cylinder 24 is installed on the top of the pressing guide plate 21, and the driving end of the first pressing lifting cylinder 24 is connected to the pressing connecting plate 16; the piston rod of the first pressing lifting cylinder 24 performs telescopic movement, so that the pressing guide rod 26 moves longitudinally along the pressing guide hole 25. At this time, the pressing frame 22 installed at the bottom of the pressing guide plate 21 can move in the vertical direction. Due to the sliding cooperation between the pressing guide hole 25 and the pressing guide rod 26, the longitudinal movement stability of the pressing frame 22 can be improved.

[0040] Furthermore, the pressing frame 22 is equipped with a pressing fixing plate 27, and the pressing fixing plate 27 is equipped with a second pressing lifting cylinder 28.

The pressing strip 23 is located below the pressing fixing plate 27, and the driving end of the second pressing lifting cylinder 28 is connected to the pressing strip 23. When the diaphragm needs to be pressed and positioned, when the pressing frame 22 moves longitudinally and gradually approaches the diaphragm, the second pressing lifting cylinder 28 installed on the pressing frame 22 works, and its piston rod passes through the pressing movable hole 29 to drive the pressing strip 23 to descend, thereby pressing and positioning the diaphragm.

[0041] The lifting drive seat 1 is provided with a first printing component 31 and a second printing component 32.

The lifting drive seat 1 is provided with a lifting drive member 33 for driving the printing drive seat 3 to move longitudinally.

[0042] The lifting drive seat 1 can move in the vertical and horizontal directions, so that the printing roller 45 of the first printing component 31 or the second printing component 32 can roll-print ink on the positioned graphene diaphragm and coat the surface of the graphene diaphragm with a corresponding ink layer; when different types of graphene diaphragms are required to print different types of inks; the ink box 4 of the first printing component 31 or the second printing component 32 respectively stores inks of different materials, and the first printing component 31 or the second printing component 32 can be selected to roll-print the ink layer on the positioned graphene diaphragm without disassembling and replacing the ink box 4 and the printing roller 45, thereby further improving practicality.

[0043] In the first embodiment, the ink boxes 4 of the first printing component 31 and the second printing component 32 can store different types of inks respectively. When the first ink is needed, the printing roller 45 of the second printing component 32 is raised, and the printing roller 45 of the first printing component 31 is lowered to perform roller printing on the membrane; when the second ink is needed, the printing roller 45 of the first printing component 31 is raised, and the printing roller 45 of the second printing component 32 is lowered to perform roller printing on the membrane.

[0045] In the third embodiment, the ink boxes 4 of the first printing component 31 and the second printing component 32 can store the same type of ink respectively. When the printing thickness needs to be increased, the printing rollers 45 of the first printing component 31 and the second printing component 32 are lowered at the same time to roll the membrane at the same time, so that the printing thickness is increased.

[0046] The lifting drive component 33 includes a printing lifting cylinder 38 installed on the lifting drive seat 1. The top of the lifting drive seat 1 is provided with an inwardly concave mounting groove 34 for mounting the cylinder body of the printing lifting cylinder 38. The lifting drive seat 1 is provided with a lifting movable hole 35. The lifting movable hole 35 is slidably installed with a printing drive rod 36. A printing connecting plate 37 is installed on the top of the printing drive rod 36. The piston rod end of the printing lifting cylinder 38 is connected to the printing connecting plate 37, and the bottom of the printing drive rod 36 is connected to the printing drive seat 3; the body of the printing lifting cylinder 38 is fixedly installed in the mounting groove 34. When the piston rod of the printing lifting cylinder 38 moves telescopically, the printing connecting plate 37 moves up and down, driving the printing drive rod 36 to move longitudinally along the lifting movable hole 35, so that the printing drive seat 3 installed at the bottom of the printing drive rod 36 moves longitudinally, so that the printing roller 45 installed on the printing drive seat 3 can approach the diaphragm.

[0047] Preferably, there are two lifting drive members 33 , one of which is a longitudinally movable printing drive rod 36 connected to the printing drive seat 3 of one of the first printing components 31 , and the other longitudinally movable printing drive rod 36 is connected to the printing drive seat 3 of the second printing component 32 .

A roller mounting seat 43 for mounting a printing roller 45 is formed at the bottom of the ink cartridge 4. An oil outlet hole 41 aligned with the printing roller 45 is formed at the bottom of the ink cartridge 4. The ink material to be printed can be passed into the ink cartridge 4 through the oil supply hose 42; the ink in the ink cartridge 4 can drip onto the surface of the printing roller 45 through the oil outlet hole 41, and the ink roller with ink adhered to it rolls the diaphragm, so that an ink layer is formed on the surface of the diaphragm to ensure the stability of printing.

[0049] Furthermore, roller mounting seats 43 are respectively formed at both ends of the bottom of the ink cartridge 4, and the printing roller 45 is arranged along the length direction of the ink cartridge 4. The roller mounting seats 43 are installed with support bearings 44 coaxially connected to the printing roller 45.

Both ends of the ink roller are connected to the support bearings 44, so that the ink roller is rotatably connected to the support bearings 44. When the ink roller needs to be driven to rotate, the drive motor 46 of one of the roller mounting seats 43 drives the ink roller to rotate, so that the ink roller with ink adhered to it rolls against the diaphragm.
