Description

Technical Field

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

[0002] The layers in graphite crystals are relatively loosely spaced and bound together by van der Waals forces, while the carbon atoms in graphene are more flexible. Therefore, by peeling graphite layer by layer, high-performance monolayer graphene can be obtained. 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, because the adhesive is not completely solidified and the groove is attached to the outer circumference of the wire, when the wire passes through the groove between the two adhesive rollers, the grooves of the two adhesive rollers facing the direction from which the wire passes will continuously squeeze and accumulate excess adhesive that cannot pass through the gap between the wire and the groove. 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

[0013] Furthermore, the adhesive module also includes a cutting blade for removing waste adhesive, a waste adhesive wheel for winding up waste adhesive, and a transmission mechanism for driving the conveyor belt, the adhesive wheel body, and the waste adhesive wheel to rotate synchronously.

[0014] Furthermore, the blade edge of the cutting blade has the same shape as the cross-sectional shape of the groove, and the blade edge of the cutting blade is attached to the annular surface of the adhesive wheel body.

[0015] Furthermore, the transmission mechanism includes a fourth gear, a fifth gear, a sixth gear, a fourth transmission gear, a fifth transmission gear, a sixth transmission gear, a third synchronous belt, a fourth synchronous belt, a fourth connecting rod, and a fifth connecting rod.

[0036] Please see Figures 1 to 8 The present invention provides an outer ring graphene coating device, comprising a wire 400 and, sequentially arranged along the wire 400, an adhesive coating module 100 for applying adhesive, a coating module 200 for applying graphite powder, a guide ring block 500, a brush 600, and an adhesive module 300 for adhering graphite powder. The adhesive module 300 includes an adhesive wheel mechanism 301 for adhesive application, an adhesive spray pipe 307 for applying adhesive to the adhesive wheel mechanism 301, a setting mechanism 302 for setting the adhesive, a drive mechanism 303 for driving the setting mechanism 302 to rotate, and a cooling mechanism 306 for condensing the adhesive.

[0037] The adhesive roller mechanism 301 includes adhesive roller bodies 3011 symmetrically arranged about the wire 400. An annular groove 3013 is machined on the annular surface of the adhesive roller body 3011. The cross-section of the groove 3013 is arc-shaped, while the cross-section of the wire 400 is circular. The radius of the circular cross-section of the wire 400 is slightly smaller than the radius of the arc-shaped cross-section of the groove 3013. The centers of the arc-shaped cross-sections of the grooves 3013 on the closest side of the two adhesive roller bodies 3011 are located at the same position, allowing the surface of the wire 400 to fully contact the adhesive in the groove 3013 when it passes through this point, thereby improving the adhesion of graphite powder. The central axis of the adhesive spray tube 307 is collinear with the line connecting the centers of the two adhesive roller bodies 3011, and the end of the adhesive spray tube 307 extends to the inner side of the groove 3013 to prevent adhesive from splashing onto the outer side of the groove 3013 during spraying.

[0038] An annular groove 3014 is formed on the side wall of the adhesive roller body 3011. The cooling mechanism 306 includes a fan 3061, an air duct 3062, and a cooling pipe 3063 movably assembled in the annular groove 3014. The cooling pipe 3063 does not rotate with the rotation of the adhesive roller body 3011. One end of the cooling pipe 3063 facing the glue spraying pipe 307 has an air outlet 3065, and the other end has an air inlet 3064. The air inlet 3064 is connected to the fan 3061 through the air duct 3062. After the glue spraying pipe 307 sprays glue into the groove 3013 on the adhesive roller body 3011, the glue rotates with the adhesive roller body 3011. At the same time, the fan 3061 starts and cools the roller through the air duct 3062. Airflow is introduced into the tube 3063. The airflow moves from the air inlet 3064 to the air outlet 3065, carrying away the heat carried by the adhesive to achieve a cooling effect. As the airflow moves from the air inlet 3064 towards the end facing the wire 400 to the air outlet 3065 towards the end facing the adhesive spray tube 307, the amount of heat carried by the airflow increases with its movement. This makes the airflow temperature at the air outlet 3065 higher than that at the air inlet 3064. Consequently, the adhesive cools down slowly under the action of the cooling tube 3063, solidifying into a viscous adhesive strip without completely solidifying. It does not begin to solidify immediately upon contact with the cooling tube 3063, which would cause the adhesive to solidify after being cooled by the cooling tube 3063 and lose its adhesive properties.

[0039] The shaping mechanism 302 includes a conveyor belt 3021 and a scraper block 310 symmetrically arranged about the wire material 400. The conveyor belt 3021 is attached to the annular surface of the adhesive roller body 3011. One end of the conveyor belt 3021 facing the adhesive spray pipe 307 is provided with a driven roller 3023 and the other end is provided with a driving roller 3022. A shaping strip 3024 that conforms to the shape of the wire groove 3013 is fixedly installed on the conveyor belt 3021. The cross-section of the shaping strip 3024 is arc-shaped, and its arc radius is equal to the radius of the circular cross-section of the wire material 400. During the operation of the conveyor belt 3021, the shaping strip 3024 and the wire groove 3013 are aligned. The 13 pieces maintain a certain gap to facilitate the shaping of the glue into an arc-shaped adhesive strip that adheres to the inner wall of the groove 3013. In order to prevent the glue from dripping from the spray tube 307 into the groove 3013, the small gap between the shaping strip 3024 and the groove 3013 causes it to accumulate at the entrance of the groove 3013 and the conveyor belt 3021, and then overflow to the outside of the groove 3013. The two ends of the driven roller 3023 extend to the outside of the conveyor belt 3021 and are fixedly installed with circular baffles 3025 that adhere to the side wall of the adhesive wheel body 3011. The circular baffles 3025 are used to block the glue inside the groove 3013.

[0040] After the shaping strip 3024 and the cooling mechanism 306 shape the adhesive, the adhesive still has adhesive properties. To prevent the adhesive from sticking to the shaping strip 3024, a scraper block 310 is provided at the exit of the conveyor belt 3021. The end shape of the scraper block 310 is the same as the cross-sectional shape of the shaping strip 3024. The end of the scraper block 310 is attached to the arc surface of the shaping strip 3024 to separate the adhesive from the shaping strip 3024.

[0041] If the shaping strip 3024 remains stationary, during the movement of the adhesive within the gap between the shaping strip 3024 and the wire groove 3013, some adhesive adheres to the shaping strip 3024, resulting in gaps in the adhesive strip formed by the condensation of the adhesive. This prevents proper adhesion of the graphite powder on the surface of the wire material 400. Therefore, the adhesive module 300 is equipped with a drive mechanism 303 to drive the conveyor belt 3021 to rotate the shaping strip 3024, reducing the adhesive force between the adhesive and the shaping strip 3024. The drive mechanism 303 includes a geared motor 3031, a first gear 3032, a second gear 3034, a third gear 3041, a first transmission gear 3036, a second transmission gear 3038, a third transmission gear 3040, a first synchronous belt 3033, a second synchronous belt 3037, a first connecting rod 3042, a second connecting rod 3035, and a third connecting rod. 3039. A first gear 3032 is fixedly mounted on the output end of the geared motor 3031. A second gear 3034 and a third gear 3041 are fixedly mounted on the side walls of the two drive rollers 3022 respectively via a first connecting rod 3042. The first gear 3032 and the second gear 3034 are connected by a first synchronous belt 3033. A second connecting rod 3035 is fixedly mounted on the side wall of the first gear 3032 relative to the geared motor 3031. A first transmission gear 3036 is fixedly mounted on the other end of the second connecting rod 3035. The first transmission gear 3036 and the second transmission gear 3038 are connected by a second synchronous belt 3037. The second transmission gear 3038 and the third transmission gear 3040 are fixedly connected by a third connecting rod 3039. The third transmission gear 3040 meshes with the third gear 3041.

[0042] The adhesive module 300 also includes a cutting blade 309 for cutting off waste adhesive, a waste adhesive wheel 308 for winding up waste adhesive, and a transmission mechanism 305 for driving the conveyor belt 3021, the adhesive wheel body, and the waste adhesive wheel 308 to rotate synchronously. The blade shape of the cutting blade 309 is the same as the cross-sectional shape of the groove 3013. The blade of the cutting blade 309 is attached to the annular surface of the adhesive wheel body 3011. The adhesive sprayed by the adhesive spray pipe 307 on the surface of the adhesive wheel body 3011 forms an adhesive layer. When the adhesive layer rotates to the position of the cutting blade 309, the blade of the cutting blade 309 can cut off the adhesive layer. The side of the cutting blade 309 is equipped with a waste adhesive wheel 308 to wind up the cut adhesive layer.

[0043] To ensure that the conveyor belt 3021, the sticky roller body 3011, and the waste rubber roller 308 maintain the same linear speed, the transmission mechanism 305 includes a fourth gear 3051, a fifth gear 3058, a sixth gear 3053, a fourth transmission gear 3054, a fifth transmission gear 3056, a sixth transmission gear 3057, a third synchronous belt 3052, a fourth synchronous belt 3055, a fourth connecting rod (not shown), and a fifth connecting rod (not shown). The fourth gear 3051 is fixedly mounted on the circular baffle 3025, and the fourth gear 305... 1. The axis of the circular baffle 3025 is collinear. The fourth gear 3051 and the sixth gear 3053 are connected by the third synchronous belt 3052. The fourth gear 3051 and the fourth transmission gear 3054 are fixedly connected by the fourth connecting rod (not shown). The fourth transmission gear 3054 and the fifth transmission gear 3056 are connected by the fourth synchronous belt 3055. The fifth transmission gear 3056 and the sixth transmission gear 3057 are fixedly connected by the fifth connecting rod (not shown). The fifth transmission gear 3056 and the fifth gear 3058 mesh.

[0044] The shaping strip 3024 is a silicone rubber strip. Silicone rubber strips are not easy to stick to glue, making it easy to separate the glue from the strip using the scraper block 310 after the glue has been shaped and solidified into a strip. In addition, silicone rubber strips have good resilience and thermal stability, are resistant to pulling and not easy to break, and are not easily affected by the heat carried by hot melt glue.

[0045] During operation, the wire 400 sequentially passes through the gluing module 100, the coating module 200, the ring block 500, the brush 600, and the adhesive module 300. The gluing module 100 applies a layer of glue to the surface of the wire 400, and then the coating module 200 applies graphite powder onto the glue. After the wire 400 passes through the ring block 500 and the brush 600 for initial screening to remove the graphite powder, it arrives at the adhesive module 300. The wire 400 passes through the gap formed by the wire grooves 3013 at the near ends of the two adhesive roller bodies 3011. The adhesive strip on the adhesive roller body 3011 adheres to the graphite powder on the surface of the wire 400, reducing the number of graphite powder layers on the surface of the wire 400. During the adhesion process of the adhesive module 300, the adhesive spray tube 307 sprays hot melt adhesive into the wire groove 3013 of the adhesive roller body 3011. The reduction motor 3031 drives the first gear 3032 to rotate. The first gear 3032 drives the second gear 3034 to rotate in the same direction through the first synchronous belt 3033. The second gear 3034 drives the second gear 3034 to rotate through the first connecting rod 3042. Figure 3As shown, the drive roller 3022 of the lower conveyor belt 3021 rotates in the same direction. Simultaneously, the first gear 3032 drives the first transmission gear 3036 to rotate in the same direction via the first connecting rod 3042. The first transmission gear 3036 drives the second transmission gear 3038 to rotate in the same direction via the second synchronous belt 3037. The second transmission gear 3038 drives the third transmission gear 3040 to rotate in the same direction via the third connecting rod 3039. Furthermore, the meshing third gear 3041 and the first connecting rod 3042 drive... Figure 3 The drive roller 3022 of the upper conveyor belt 3021 rotates in opposite directions. The two drive rollers 3022 respectively drive the conveyor belt 3021 to rotate, which in turn drives the driven roller 3023 to rotate in the same direction. The driven roller 3023 drives the fourth gear 3051 to rotate in the same direction via a circular baffle 3025. The fourth gear 3051 drives the sixth gear 3053 to rotate in the same direction via a third synchronous belt 3052, which in turn drives the waste rubber wheel 308 to rotate in the same direction. Simultaneously, the fourth gear 3051 drives the fourth transmission gear 3054 to rotate in the same direction via a fourth connecting rod (not shown). The fourth transmission gear 3054 drives the fifth transmission gear 3056 to rotate in the same direction via a fourth synchronous belt 3055. The transmission gear 3056 drives the sixth transmission gear 3057 to rotate in the same direction via the fifth connecting rod (not shown), and then drives the adhesive roller body 3011 to rotate in the opposite direction via the meshing fifth gear 3058, so that the moving speed of the shaping strip 3024 on the conveyor belt 3021, the moving speed of the adhesive strip on the adhesive roller body 3011, and the speed of the waste adhesive roller 308 winding up the waste adhesive strip are equal. During the rotation of the adhesive roller body 3011, the fan 3061 starts and introduces airflow into the cooling pipe 3063 through the air duct 3062. The airflow moves from the air inlet 3064 to the air outlet 3065, carrying away the heat carried by the glue to achieve a cooling effect, so that the glue solidifies into a viscous adhesive strip.

[0046] 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.
