Abstract

This invention discloses a graphene coating processing apparatus, relating to the technical field of graphene coating equipment. It includes a wire and, sequentially arranged along the wire's extension direction, a coating module, a graphite powder coating module, a ring block, a brush, and a bonding module. The bonding module includes a bonding wheel mechanism, a spray tube, and a shaping mechanism. The graphene coating processing apparatus provided by this invention features a shaping mechanism. A shaping plate, in conjunction with the groove of the bonding wheel body, compresses the adhesive into a shape that adheres to the inner wall of the groove. This prevents adhesive from accumulating at the closest end between the wire and the groove without affecting the adhesion of graphite powder. Inside the shaping mechanism are a heat-absorbing chamber and a reflux chamber for coolant flow, allowing the adhesive to slowly cool and solidify into a viscous strip as it passes through the gap between the shaping plate and the groove, preventing liquid adhesive from dripping from the groove onto the wire surface. A temperature sensor, in conjunction with a valve on the spray tube, prevents adhesive from clogging the end of the shaping plate near the spray tube.

Description

Technical Field

[0001] This invention relates to the field of graphene coating equipment technology, specifically to a graphene coating processing device. Background Technology

[0002] Graphite is an allotrope of carbon, a gray-black, opaque solid with stable chemical properties, corrosion resistance, and does not readily react with acids, alkalis, or other agents. With the advancement of science and technology, people have used advanced equipment to peel off graphite layer by layer, ultimately obtaining high-performance single-layer graphene. Graphene anti-corrosion coatings are coatings with high anti-corrosion capabilities obtained by adding graphene powder to solvent-based coatings and dispersing it evenly.

[0003] According to the graphene coating device for the outer ring of a wire disclosed in patent number CN110328100B, a layer of adhesive is first applied to the surface of the wire material, followed by the spraying of graphite powder onto the adhesive layer. Then, multiple sets of adhesive rollers are used to remove the graphite layer attached to the surface of the wire material by adhesive bonding, thereby obtaining a wire with only one or a few layers of graphite. Each set of adhesive rollers consists of two rollers, each with a semi-circular groove that matches the diameter of the wire material. The centers of the grooves at the closest ends of the two adhesive rollers coincide. The adhesive bonding first requires spraying adhesive into the groove of the adhesive roller using an adhesive spraying block. Then, an airflow block is used to solidify the liquid adhesive into a thicker consistency, but not completely solidify it, so as to remove the graphite powder from the surface of the wire material without leaving any residue on the surface of the wire material.

[0004] However, during the adhesion process of the adhesive rollers, it is difficult for the spray tube to precisely spray an appropriate amount of adhesive into the wire groove. When the liquid adhesive condenses into a thick adhesive strip by the airflow block and passes through the wire groove between the two adhesive rollers, because the inner wall of the wire groove of the adhesive roller is almost in contact with the surface of the wire, leaving only a very narrow gap, only a small amount of adhesive passes through the gap. The excess adhesive continuously accumulates on the side of the wire groove of the two adhesive rollers facing the direction from which the wire comes. Some of this accumulated adhesive will spill to both sides of the adhesive rollers, and the other part will gradually solidify, thus affecting the subsequent adhesion of the adhesive rollers to the graphite layer on the surface of the wire. Summary of the Invention

[0005] The purpose of this invention is to provide a graphene coating processing apparatus to solve the problem of easy glue accumulation during the adhesion of existing adhesive rollers as mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The present invention provides a graphene coating processing device, comprising a wire and a coating module for applying adhesive, a coating module for applying graphite powder, a guide ring block, a brush, and a bonding module for adhering graphite powder, arranged sequentially along the extension direction of the wire. The bonding module includes a bonding wheel mechanism, a spray pipe for spraying adhesive onto the bonding wheel mechanism, and a setting mechanism for setting the adhesive.

[0008] Furthermore, the material-adhesive wheel mechanism includes material-adhesive wheel bodies symmetrically arranged with respect to the wire material. Annular grooves are machined on the annular surface of the material-adhesive wheel bodies, and the centers of the cross-sections of the adjacent side grooves of the two material-adhesive wheel bodies are located at the same position.

[0009] Furthermore, the shaping mechanism includes an arc-shaped mounting plate extending along the annular surface of the adhesive wheel body. The arc-shaped mounting plate has a C-shaped cross-section. A shaping plate is fixedly mounted on the side wall of the arc-shaped mounting plate facing the groove. The center of the shaping plate and the cross-section of the groove are located at the same position.

[0010] Furthermore, a chamber for coolant flow is formed between the shaping plate and the arc-shaped mounting plate. The chamber is divided into a heat absorption chamber and a return chamber by a heat insulation plate. The end of the return chamber facing the spray tube has a notch. The heat absorption chamber and the return chamber are connected through the notch. The end of the arc-shaped mounting plate opposite to the spray tube is respectively provided with a water inlet pipe communicating with the heat absorption chamber and a water outlet pipe communicating with the return chamber. A water tank is connected to the outside of the water outlet pipe, and a water pump assembled inside the water tank is connected to the outside of the water inlet pipe.

[0011] Furthermore, heat-conducting plates are staggered along the coolant flow direction inside the heat-absorbing cavity.

[0012] Furthermore, the central axis of the glue spray tube is collinear with the line connecting the centers of the two adhesive roller bodies, and the end of the glue spray tube extends to the inner side of the groove. The arc-shaped mounting plate has a receiving groove at one end facing the glue spray tube, a temperature sensor is provided on the side wall of the receiving groove, and a valve is provided at the end of the glue spray tube.

[0013] Furthermore, the adhesive module also includes a cutting blade for cutting off the adhesive strip and a waste adhesive wheel for winding up the adhesive strip, wherein the end of the cutting blade is provided with a cutting edge adapted to the wire groove.

[0014] Furthermore, both the shaping plate and the heat-conducting plate are copper plates.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] This invention provides a graphene coating processing device, which includes a shaping mechanism. A shaping plate, in conjunction with the groove of the adhesive roller body, compresses the adhesive into a shape that adheres to the inner wall of the groove. This prevents adhesive from accumulating at the closest end between the material and the groove without affecting the adhesion of graphite powder. The shaping mechanism includes a heat-absorbing chamber and a reflux chamber for coolant flow, allowing the adhesive to slowly cool and solidify into a viscous strip as it passes through the gap between the shaping plate and the groove. This prevents liquid adhesive from dripping from the groove onto the material surface. A temperature sensor, in conjunction with a valve on the adhesive spraying pipe, prevents adhesive from clogging the end of the shaping plate near the spraying pipe. Attached Figure Description

[0032] Please see Figures 1 to 6The present invention provides a graphene coating processing device, including a wire 500 and a coating module 100 for applying adhesive, a coating module 200 for applying graphite powder, a guide ring block 300, a brush 400, and a bonding module 600 for adhering graphite powder, which are arranged sequentially along the extension direction of the wire 500. The bonding module 600 includes a bonding wheel mechanism, a spray pipe 603 for spraying adhesive onto the bonding wheel mechanism, and a setting mechanism 700 for setting the adhesive.

[0033] The adhesive wheel mechanism includes adhesive wheel bodies 601 symmetrically arranged about the wire 500. Annular grooves 602 are machined on the annular surface of the adhesive wheel bodies 601. The centers of the cross-sections of the grooves 602 on adjacent sides of the two adhesive wheel bodies 601 are located at the same position. The adhesive wheel bodies 601 rotate as the wire 500 moves. Adhesive is sprayed into the grooves 602 on their annular surfaces by the adhesive spray tube 603, which adheres the graphite powder to the surface of the wire 500, thus thinning the graphite layer.

[0034] To prevent excessive glue from accumulating when the adhesive roller body 601 adheres to the graphite powder on the surface of the material 500, thus affecting subsequent adhesion and separation, the shaping mechanism 700 includes an arc-shaped mounting plate 701 extending along the annular surface of the adhesive roller body 601. The arc-shaped mounting plate 701 has a C-shaped cross-section. A shaping plate 702 is fixedly mounted on the side wall of the arc-shaped mounting plate 701 facing the groove 602. The center of the cross-section of the shaping plate 702 and the groove 602 are located at the same position. When the glue spraying tube 603 sprays glue into the groove 602, the glue accumulates at the lower end of the groove 602. As the adhesive roller body 601 rotates, the gap between the shaping plate 702 and the groove 602 limits the thickness of the glue layer, making the glue a thin layer after passing through the gap.

[0035] To prevent liquid adhesive from falling from the adhesive roller body 601 onto the wire material 500 during rotation and affecting the adhesion of the graphite layer, a chamber for coolant flow is formed between the shaping plate 702 and the arc-shaped mounting plate 701. This chamber is divided into a heat absorption chamber 705 and a return flow chamber 706 by a heat insulation plate 703. The return flow chamber 706 has a notch 707 at one end facing the adhesive spray tube 603, and the heat absorption chamber 705 and the return flow chamber 706 are connected through the notch 707. The arc-shaped mounting plate 701 has a water inlet pipe 709 at one end relative to the adhesive spray tube 603, which communicates with the heat absorption chamber 705 and the return flow chamber 706, respectively. The water outlet pipe 708 is connected to a water tank, and the water inlet pipe 709 is connected to a water pump installed inside the water tank. As the adhesive roller body 601 rotates, the adhesive enters the gap between the shaping plate 702 and the wire groove 602 to form a thin layer of adhesive. At the same time, the water pump introduces coolant into the heat absorption chamber 705 through the water inlet pipe 709. The coolant flows from the end of the heat absorption chamber 705 away from the adhesive spraying pipe 603 to the end closer to the adhesive spraying pipe 603, carrying away the heat of the adhesive and causing the adhesive to gradually condense into a viscous adhesive strip. Then, the coolant enters the return chamber 706 through the notch 707 and returns to the water tank through the water outlet pipe 708.

[0036] Heat-conducting plates 704 are staggered along the coolant flow direction inside the heat absorption cavity 705. Both the shaping plate 702 and the heat-conducting plates 704 are copper plates. Copper has good thermal conductivity. The heat-conducting plates 704, together with the shaping plate 702, absorb the heat of the adhesive, so that the coolant can absorb the heat. At the same time, the irregularly arranged heat-conducting plates 704 can break the thermal boundary layer when the coolant flows, improve the heat absorption efficiency of the coolant, and thus improve the condensation effect on the adhesive.

[0037] The central axis of the glue spray tube 603 is collinear with the line connecting the centers of the two adhesive roller bodies 601, and the end of the glue spray tube 603 extends to the inner side of the groove 602. An arc-shaped mounting plate 701 has a receiving groove 710 at one end facing the glue spray tube 603. A temperature sensor is provided on the side wall of the receiving groove 710. A valve 6031 is provided at the end of the glue spray tube 603. When the adhesive roller body 601 rotates, some glue enters the gap between the shaping plate 702 and the groove 602, while excess glue accumulates on the shaping plate 702. As time goes by, the glue accumulates in the receiving tank 710, and the glue level gradually rises. When the glue level approaches the position of the temperature sensor, the temperature detected by the temperature sensor also increases. When the temperature reaches the predetermined value, the valve 6031 at the end of the glue spraying tube 603 closes, stopping the glue spraying. After a certain period of time, the accumulated glue enters the gap between the shaping plate 702 and the wire groove 602 as the adhesive roller body 601 rotates. At this time, the valve 6031 opens, and the glue spraying tube 603 continues to spray glue.

[0038] The adhesive module 600 also includes a cutting blade 604 for cutting off the adhesive strip and a waste rubber wheel 605 for winding up the adhesive strip. The end of the cutting blade 604 is provided with a cutting edge that is adapted to the groove 602. When graphite powder adheres to the adhesive strip on the adhesive wheel body 601, the adhesive strip is cut off by the cutting blade 604 and the adhesive strip with graphite powder is wound up by the waste rubber wheel 605.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
