The graphene dispersion liquid can be prepared by dissolving graphene powder into a solvent, adding a dispersing agent and performing ultrasonic treatment, and is not described in detail.
Further, referring to fig. 4, in order to enable the first fiber cloth 5 and the second fiber cloth 6 to smoothly enter the corresponding negative pressure channels 16, an inlet 9 of the composite bin 8 is respectively provided with an inlet first guide roller 11 and an inlet second guide roller 12, and an inlet third guide roller 14 and an inlet fourth guide roller 15 are respectively arranged between the inlet 9 and the separation block 13; the first fiber cloth 5 enters the corresponding negative pressure channel 16 after being guided by the inlet first guide roller 11 and the inlet third guide roller 14, and the second fiber cloth 6 enters the corresponding negative pressure channel 16 after being guided by the inlet second guide roller 12 and the inlet fourth guide roller 15.
In an embodiment, considering that when the coating port 19 coats the graphene dispersion liquid on the cloth, the graphene dispersion liquid is extruded from the coating port 19 and then pushes up the cloth, so that a gap is generated between the cloth and the end surface of the separation block 13, and air is permeated to generate bubbles, for this purpose, referring to fig. 3 and 5, the top pressure assembly 20 is further included, and the top pressure assembly 20 is disposed on the composite bin 8, and the top pressure assembly 20 includes a housing 201 integrally connected with the composite bin 8, a expansion plate 202 slidably embedded in the housing 201, a spring 203 disposed in the housing 201 and abutting against the expansion plate 202, and a flexible pressing block 204 disposed on the expansion plate 202, where the flexible pressing block 204 is located on the end surface of the expansion plate 202 facing the coating port 19;
Specifically, when the first fiber cloth 5 or the second fiber cloth 6 passes between the coating port 19 and the flexible pressing block 204, the flexible pressing block 204 on the expansion plate 202 always presses the first fiber cloth 5 or the second fiber cloth 6 at the coating port 19 under the action of the elasticity of the spring 203; when the graphene dispersion liquid is extruded from the coating port 19, the flexible pressing block 204 can always wrap the periphery of the coating port 19, so that external air is prevented from entering between the coating port 19 and cloth, and meanwhile, the flexible pressing block 204 can also adaptively deform along with the extrusion of the graphene dispersion liquid, so that the normal coating of the graphene dispersion liquid is not influenced.
Further, referring to fig. 3 and 5, a pump assembly 21 is disposed in the separation block 13, the pump assembly 21 includes a pump cavity 211, gears 214 meshed with each other are rotatably disposed in the pump cavity 211, two ends of the pump cavity 211 are respectively provided with a liquid outlet end 212 and a liquid inlet end 213, and the liquid outlet end 212 is communicated with the coating port 19;
Specifically, the gear 214 is engaged and rotated, so that the graphene dispersion liquid at the liquid inlet end 213 is sucked into the pump cavity 211, and the graphene dispersion liquid is pumped out from the liquid outlet end 212 to the coating port 19 along with rotation of the gear 214;
It should be noted that, pumping through pump liquid subassembly 21 of gear pump structure carries out the pump sending to the graphite alkene dispersion, on the one hand can carry out stable control to the flow of graphite alkene dispersion, on the other hand can utilize rotatory gear 214 to carry out continuous dispersion to the graphite alkene dispersion, makes graphite alkene dispersion mix more evenly, promotes the homogeneity that follow-up graphite alkene dispersion was coated.
In yet another embodiment, considering that the graphene dispersion liquid coated on the first fiber cloth 5 and the second fiber cloth 6 cannot be completely and uniformly spread by itself in the compounding process, so that the thickness of the graphene dispersion liquid in the compound cloth 7 is inconsistent, for this purpose, referring to fig. 6, 7 and 8, a spreading assembly 25 is disposed in the compound channel 22, the spreading assembly 25 includes a spreading frame 251 fixed in the compound channel 22 and a reciprocating shaft 254 movably disposed in the spreading frame 251, two sides of the spreading frame 251 are respectively provided with a liquid inlet 252 and a liquid outlet 253, openings are formed at the upper end and the lower end of the spreading frame 251, a plurality of spreading plates 255 are disposed on the reciprocating shaft 254, a spreading area is formed between adjacent spreading plates 255, and through holes 256 are formed on the spreading plates 255;
Specifically, the first fiber cloth 5 and the second fiber cloth 6 enter the composite channel 22 and then pass through the upper end and the lower end of the spreading frame 251 respectively, so that the graphene dispersion liquid between the first fiber cloth 5 and the second fiber cloth 6 enters each spreading region in the spreading frame 251 from the liquid inlet 252, and meanwhile, the reciprocating shaft 254 drives each spreading plate 255 to reciprocate, so that the graphene dispersion liquid in the spreading frame 251 is subjected to back-and-forth spreading vibration, even if the graphene dispersion liquid in each spreading region in the initial stage is unevenly distributed, the graphene dispersion liquid in each spreading region can flow through the through holes 256 along with the reciprocating movement of the spreading plates 255 until the graphene dispersion liquid in each spreading region finally tends to be consistent, and the graphene dispersion liquid after being uniformly spread is discharged from the liquid outlet 253 and recoated between the first fiber cloth 5 and the second fiber cloth 6 under the driving of the subsequent graphene dispersion liquid, so that the thickness of each part in the composite cloth 7 is kept consistent, and the defect that the composite cloth 7 is empty due to the thickness difference of the graphene dispersion liquid in the subsequent drying process is avoided.
Further, referring to fig. 8, in order to enhance the spreading effect of the graphene dispersion liquid, the liquid inlet 252 is gradually reduced toward the opening at one side of the spreading area, and the liquid outlet 253 is gradually increased toward the opening at one side of the spreading area; in this way, when the graphene dispersion liquid enters and exits the paving, the channel opening is gradually reduced, and the pressure to which the graphene dispersion liquid is subjected is gradually increased, so that the flow velocity of the graphene dispersion liquid is increased, and the dispersing and paving effects of the graphene dispersion liquid can be further improved.
Still further, referring to fig. 4 and 6, in order to enhance the tightness of the composite fabric 7, two ends of the composite channel 22 are respectively provided with a first composite press roller 23 and a second composite press roller 24, when the first fiber fabric 5 and the second fiber fabric 6 enter the composite channel 22, the first composite press roller 23 guides and primarily rolls the first fiber fabric 5 and the second fiber fabric 6, so that the first fiber fabric 5 and the second fiber fabric 6 can stably enter the composite channel 22, after the composite is completed, the composite fabric 7 is further rolled by the second composite press roller 24, so that the graphene dispersion between the first fiber fabric 5 and the second fiber fabric 6 is distributed more uniformly and compactly, and the composite strength of the graphene dispersion and the fabric is enhanced.
In an embodiment, referring to fig. 9, an air pump 26 communicating with the air channel 18 and an infusion tube 40 communicating with the liquid inlet end 213 are installed on the outer wall of the composite bin 8; the air at the air suction port 17 is continuously pumped out through the air pump 26, so that the cloth can be always attached to the end face of the separation block 13, and the graphene dispersion liquid is conveyed to the liquid inlet end 213 through the liquid conveying pipe 40, so that the graphene dispersion liquid can be continuously pumped by the subsequent liquid pumping assembly 21;
In addition, considering that the winding rotation speed of the composite winding drum 3 is constant, as the thickness of the composite cloth 7 on the composite winding drum 3 is continuously increased, the radius of the whole composite cloth 7 is continuously increased, so that the linear speed of the composite cloth 7 is continuously increased, in order to keep the coating amount of the graphene dispersion liquid in each part of the composite cloth 7 consistent, the amount of the graphene dispersion liquid extruded at the coating opening 19 should also be synchronously increased with the linear speed of the composite cloth 7, for this purpose, referring to fig. 9, a set of gears 214 are coaxially connected with a gear shaft 27 penetrating through the composite bin 8, a set of second composite press rollers 24 are coaxially connected with a press roller shaft 29 penetrating through the composite bin 8, a transmission shaft 28 is rotatably arranged on the outer wall of the composite bin 8, a first transmission belt 30 is connected between the gear shaft 27 and the transmission shaft 28, and a second transmission belt 31 is connected between the transmission shaft 28 and the press roller shaft 29;
Specifically, as the second composite press roller 24 is tightly pressed on the composite cloth 7, when the composite cloth 7 moves under the traction of the composite winding drum 3, the second composite press roller 24 can be driven to synchronously move, and the transmission shaft 28 is driven to rotate under the transmission of the second transmission belt 31, so that the gear shaft 27 is driven to rotate under the transmission of the first transmission belt 30, and the gear 214 is driven to rotate, so that the pumping of graphene dispersion liquid is realized; when the linear speed of the composite cloth 7 is increased, the rotating speed of the second composite press roller 24 is also increased, so that the rotating speed of the gear 214 is also increased synchronously, and the pumping quantity of the graphene dispersion liquid in unit time can be correspondingly regulated by regulating the rotating speed of the gear 214, so that the quantity of the graphene dispersion liquid extruded at the coating port 19 is matched with the linear speed of the composite cloth 7;
It should be noted that, in practical application, the rotation speed of the gear 214 is matched with the rotation speed of the second composite press roller 24 by setting the transmission ratio between the press roller shaft 29, the transmission shaft 28 and the gear shaft 27, and when the rotation speed of the second composite press roller 24 is gradually increased, the rotation speed of the gear 214 can also be synchronously increased, so that the coating amounts of the graphene dispersion liquid at different positions on the first fiber cloth 5 and the second fiber cloth 6 are kept consistent, and the quality of the subsequent composite process is improved.
Further, referring to fig. 10, in order to avoid the influence of the relative sliding between the second composite press roller 24 and the composite cloth 7 on the synchronism of the second composite press roller 24 and the composite cloth 7, it is necessary to ensure that the second composite press roller 24 and the composite cloth 7 are always tightly attached to each other, so that the composite cloth 7 can apply a sufficient friction force to the second composite press roller 24, thereby driving the second composite press roller 24 to rotate synchronously; because the thicknesses of the composite cloth 7 with different specifications also have certain difference, in order to enable the second composite press roll 24 to be tightly attached to the composite cloth 7 all the time, an adjusting groove 33 is formed at the outlet 10 of the composite bin 8, an adjusting block 34 is embedded in the adjusting groove 33 in a sliding manner, and the press roll shaft 29 is rotatably arranged in the adjusting block 34; a sliding groove 35 is formed in the outer side of the composite bin 8, a sliding block 36 is embedded in the sliding groove 35 in a sliding manner, and a connecting rod 37 is hinged between the sliding block 36 and the adjusting block 34; a screw rod 38 is rotatably arranged in the sliding groove 35, the sliding block 36 is in threaded connection with the screw rod 38, and a turntable 39 is arranged on the screw rod 38;
The rotary table 39 is rotated to drive the screw rod 38 to rotate, so that the sliding block 36 is driven to horizontally slide along the sliding groove 35, and under the action of the connecting rod 37, the adjusting block 34 can be driven to vertically slide along the adjusting groove 33, and then the distance between the second composite press roller 24 and the composite cloth 7 is adjusted, so that the second composite press roller 24 and the composite cloth 7 are tightly attached, and the relative sliding between the second composite press roller 24 and the composite cloth 7 is avoided.
In yet another embodiment, referring to fig. 11, the reciprocating assembly 32 further includes a reciprocating assembly 32, the reciprocating assembly 32 includes a fixing frame 321 fixed on the outer wall of the composite bin 8, a rotating drum 322 rotatably mounted on the fixing frame 321, and a sliding frame 324 slidably embedded in the fixing frame 321, the sliding frame 324 is fixedly connected with the extending end of the reciprocating shaft 254, the rotating drum 322 is fixedly connected with the transmission shaft 28 coaxially, an elliptical groove 323 is formed on the rotating drum 322, and a bayonet lock 325 adapted to the elliptical groove 323 is provided on the sliding frame 324;
Specifically, when the second composite pressing roller 24 drives the transmission shaft 28 to rotate, the rotating drum 322 is driven to rotate synchronously, and the bayonet 325 is always limited in the elliptical groove 323, so that the sliding frame 324 is driven to slide back and forth relative to the fixed frame 321, and the reciprocating shaft 254 is driven to stretch back and forth, so that the back and forth paving action of the paving plate 255 is realized;
It should be noted that, by setting the reciprocating assembly 32, synchronous movement of the spreading plate 255 and the second composite pressing roller 24 can be realized, and when the second composite pressing roller 24 increases the rotation speed along with the increase of the linear speed of the composite cloth 7, the movement frequency of the spreading plate 255 also increases, so as to ensure the spreading effect of the graphene dispersion liquid at different positions in the composite cloth 7.

S1, respectively entering a first fiber cloth 5 and a second fiber cloth 6 into a corresponding negative pressure channel 16;
