Description

Technical Field

[0001] The utility model relates to the technical field of graphene processing, in particular to a pressing mechanism for processing layered graphene membranes. Background Art

[0002] Graphene is a two-dimensional material with a thickness of only one carbon atom and a hexagonal honeycomb lattice composed of carbon atoms in sp2 hybrid orbitals. Graphene is the thinnest but also the hardest nanomaterial in the world. It is almost completely transparent and absorbs only 2.3% of light. Its thermal conductivity is as high as 5300W / m·K, which is higher than carbon nanotubes and diamonds. Its electron mobility at room temperature exceeds 15000cm2 / V·s, which is higher than that of carbon nanotubes or monocrystalline silicon. Its resistivity is only about 6-10Ω·cm, which is lower than that of copper or silver. Graphene is suitable for making transparent touch screens, light panels, and even solar cells and supercapacitors.

[0003] However, the current production and application of graphene diaphragms are at a relatively low level of industrialization, and the industrial application equipment of graphene diaphragms is very lacking, such as the lamination mechanism of graphene diaphragms. The utility model with application number CN202021519569.6 discloses a diaphragm lamination mechanism, including a frame, an upper pressure roller, a lower pressure roller, a servo motor and a planetary reducer, wherein the output end of the servo motor is connected to the input end of the planetary reducer, and a first bearing, a second bearing, a third bearing and a fourth bearing are arranged in the frame, and the lower pressure roller is arranged below the lower pressure roller. The upper pressure roller provides downward pressure to press the graphene diaphragm onto the substrate, and the lower pressure roller provides the power for rotating the feeding, and the upper pressure roller is driven to rotate in linkage, in order to increase the output torque of the lower pressure roller.

[0004] When rolling a multi-layer composite graphene membrane, the existing rolling mechanism adopts a double-roller structure with a transmission connection between the two rollers. When the distance between the two rollers needs to be adjusted for different thicknesses, it is difficult to adjust, which will affect the linkage of the transmission structure and affect the rolling.

[0012] Furthermore: longitudinally arranged second adjustment grooves are respectively formed on both sides of the driving frame, the first bearing seat is fixedly installed in the second adjustment groove, and the second bearing seat is slidably installed in the second adjustment groove.

[0013] Further: the first bearing seat is installed with a transverse fixing block, the transverse fixing block passes laterally outward, and the body of the telescopic driving member is installed on the transverse fixing block.

[0014] Furthermore: the driving frame is equipped with a plurality of driving sprockets meshing with the driving chain for transmission, one of which is installed on the outer side wall of the driving frame.

[0018] The beneficial effects of the utility model are as follows: when the thickness of the rolling needs to be adjusted, the distance between the first bearing seat and the second bearing seat is adjusted by cooperating with the driving sprocket through the telescopic driving member. Since the outer ends of the first rolling cylinder and the second rolling cylinder are connected to the universal shaft, when the heights of the first bearing seat and the second bearing seat change, it will not affect the normal rotation of the first rolling cylinder and the second rolling cylinder. The universal shaft always maintains the transmission action, and the rolling operation is maintained while adjusting, and the stability is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

Since the second rolling bearing seat 13 is slidably installed in the first adjustment groove 11, the height of the first rolling bearing can be adjusted to change the distance between the first rolling cylinder 14 and the second rolling cylinder 15, and the multi-layer diaphragm can be rolled into a diaphragm of a composite structure with different thicknesses.

[0036] The mounting base 3 is also equipped with a driving frame 2 located next to the rolling frame 1, and the driving frame 2 is equipped with a first bearing seat 22 and a second bearing seat 23.

[0037] When the thickness of the rolling needs to be adjusted, the distance between the first bearing seat 22 and the second bearing seat 23 is adjusted by cooperating with the driving sprocket through the telescopic driving member 24.

[0043] Furthermore, a through groove 28 is opened on the top of the driving frame 2 for the driving chain 25 to enter, and a transmission seat 29 is arranged above the through groove 28.
