Description

Technical Field

[0001] The invention relates to the technical field of electric heating film preparation, and in particular to a fully automatic graphene electric heating film processing device. Background Art

[0002] my country's territory ranks among the largest in the world, with a vast area and a large temperature difference between the north and the south. In the northern regions with severe winters, heating is usually provided by burning stoves or radiators in the cold winter. However, for environmental protection reasons, combustion heating has gradually been eliminated. In some remote areas, heating is temporarily difficult to supply, resulting in extremely cold indoor temperatures in winter, affecting people's daily lives. In order to facilitate heating and reduce environmental pollution, electric heating films are used for heating.

[0003] The graphene heating film is made by sandwiching a graphene conductor between two base films and then generating heat by electrifying the graphene. During the preparation of the graphene heating film, if the hot air flow during drying and curing is uneven, different parts of the heating film will receive different amounts of heat, resulting in uneven drying, which will in turn affect the quality of the heating film. Summary of the invention

[0004] To achieve the above purpose, the present invention is implemented through the following technical solutions: a fully automatic graphene electric heating film processing equipment, including a bracket, the number of the brackets is two, a winding roller is rotatably connected at the interval between the two brackets, a side of the bracket close to the winding roller is rotatably connected to an unwinding roller, the winding roller and the unwinding roller are located on the same vertical plane, a motor is fixedly connected to the outside of the bracket, the output end of the motor is fixedly connected to the unwinding roller, the unwinding roller and the winding roller are connected through a transmission member, and a control box is fixedly connected to the outside of the bracket;

[0005] A coating assembly, the coating assembly is fixedly mounted between the two brackets, and the coating assembly is located at an end away from the unwinding roller;

[0006] A pressure roller assembly, the pressure roller assembly is rotatably connected to the bracket, and the pressure roller assembly is located above the coating assembly;

[0007] A drying component, the drying component is rotatably connected to the outer side of the bracket, and the drying component is located on the top of the bracket;

[0008] Wherein, the drying component includes a fixed plate, which is rotatably connected to the intervals of the two brackets, a shell is fixedly connected at the middle of the top of the fixed plate, and rollers are rotatably connected at both ends of the fixed plate. The rollers arranged at both ends of the fixed plate can guide the material to run in a straight line along a specific path, which is very important for ensuring that the material does not deviate, twist or fold during the drying process. At the same time, the material may swing due to airflow, tension changes and other reasons during the processing. The rollers can effectively limit the swing amplitude of the material to keep it in a relatively stable state. There are two rollers, and the two rollers are symmetrically arranged with the shell as the center. A heating plate is fixedly connected at the middle of the inner wall of the shell. The base film roll is placed on the unwinding roller, so that the base film passes through the middle of the pressing roller assembly and the coating assembly, and then returns to the winding roller through the drying assembly. The motor is connected to an external power supply to work, and the motor drives the unwinding roller to rotate, thereby driving the winding roller to rotate through the transmission member. At this time, the winding roller and the unwinding roller work synchronously, and they can run at the same linear speed to ensure that the material maintains a stable conveying speed throughout the production process, which can avoid the speed inconsistency. The problems such as material stretching, deformation or accumulation are avoided, thereby improving production efficiency. The base film passes through the drying assembly through the middle of the outer shell and the fixed plate. At this time, the heating plate in the middle dries and solidifies the graphene on the surface of the base film, removes the solvent, and forms a stable electric heating film with the graphene powder and the binder. At the same time, the air enters the inner part of the outer shell through the side holes on the outside of the outer shell through the inclined plate. The air contacts the heating plate, and the air carries the heat and moves outward along the connecting plate and the bending plate. The evaporation of water in the graphene electric heating film can be accelerated by optimizing the flow of hot air. Rapid evaporation of water can shorten the drying time. Drying time is shortened and production efficiency is improved. By arranging the bending plate, the hot air can be guided to different areas of the electric heating film to avoid local overheating or insufficient drying, which may lead to performance degradation or even damage of the electric heating film. A connecting plate is fixedly connected to the side of the shell close to the heating plate, and a bending plate is fixedly connected to the side of the connecting plate away from the heating plate. A through hole is provided on the side of the connecting plate close to the bending plate, and the through hole penetrates the connecting plate and extends to the bending plate. An inclined plate is fixedly connected to the outer side of the shell, and the inclined plate is located at the interval between the connecting plate and the heating plate.

[0009] Preferably, a square groove is formed on one side of the bracket close to the fixed plate, a slider is slidably connected to the inner wall of the square groove, an end of the slider away from the square groove is rotatably connected to a connecting rod, an end of the connecting rod away from the slider is rotatably connected to the bottom of the fixed plate, and a cylinder is fixedly connected to the inner wall of the square groove. The size of the base film tension will affect the uniformity of distribution of the conductive material in the electric heating film, and then affect the uniformity of resistance. When the base film tension is uniform and moderate, the conductive material is more evenly distributed in the electric heating film, and the consistency of resistance is better. When the base film tension is large, the electric heating film will be pulled during the drying and curing process. The film can be stretched tighter, making it easier to maintain a flat state. Appropriate base film tension can keep the electric heating film at a stable size during the drying and curing process. Too much or too little tension may cause the electric heating film to change in size, affecting the accuracy and consistency of the product. When the tension of the base film becomes smaller, the cylinder works to push the slider to move inside the square groove, and the slider drives the connecting rod to move toward the direction of the cylinder. At this time, under the support of the connecting rod, the inclination angle of the fixed plate increases, which increases the tension of the base film. The output end of the cylinder is fixedly connected to the slider, and a limiting member is fixedly connected to the inner wall side of the shell.

[0010] Preferably, the limiting member includes a round rod, which is slidably connected to the outer shell, the round rod is located inside the outer shell, the bottom of the round rod is fixedly connected to an extension rod, there are two round rods, the two round rods are symmetrically arranged with the extension rod as the center, the extension rod is arranged vertically to the drum, the bottom of the extension rod is rotatably connected to a ball, the top of the extension rod is fixedly connected to a spring, under the elastic force of the spring, the ball contacts the top of the base film, so as to prevent the base film from twisting and vibrating during the drying process, which affects the quality of the graphene heating film, and the end of the spring away from the extension rod is fixedly connected to the inner wall of the outer shell.

[0011] Preferably, the coating assembly includes an ink cartridge, the ink cartridge is fixedly connected to the bracket, the two sides of the ink cartridge are fixedly connected to the two brackets, the ink cartridge is set as an L-shaped plate, the bracket is rotatably connected to the outer side of the ink cartridge with a rotating shaft, the outer side of the rotating shaft is fixedly connected to a cylinder, the cylinder is located in the middle of the two sides of the ink cartridge, a trapezoidal groove is opened on the outer side of the cylinder, the slurry inside the ink cartridge is flush with the inner wall of the semicircular groove, the rotating shaft drives the cylinder to rotate counterclockwise, and the cylinder drives the outer convex strip to rotate, so that the convex strip and the slurry inside the semicircular groove are aligned. The convex strips stained with ink then come into contact with the base film on the pressure roller, and extrusion is generated between the convex strips and the pressure roller. The convex strips are forced to move toward the direction of the rotating shaft, causing the spring plate to shrink and deform. Since the surfaces of different base materials may have slight unevenness, the elastic pressure of the spring plate can make the cylinder better adapt to the changes in the base surface, ensuring that the graphene slurry can be evenly coated on the base film. At the same time, it can also enhance the bonding force between the slurry and the base film, and improve the stability of the electric heating film. The bottom edge of the trapezoidal groove close to the rotating shaft The inner wall of the trapezoidal groove is slidably connected with a convex strip, and the outer side of the convex strip is fixedly connected with a spring plate, there are two spring plates, and the two spring plates are symmetrically arranged with the convex strip as the center, and the end of the spring plate away from the convex strip is fixedly connected to the inner wall of the trapezoidal groove, and the top of the ink cartridge away from the rotating shaft is provided with a feed port, and the side of the ink cartridge close to the cylinder is fixedly connected with a scraper, and the side of the ink cartridge close to the scraper is provided with a guide groove, and the rotating shaft drives the cylinder to rotate, and after the convex strip contacts the base film on the outer side of the pressure roller, it continues to rotate, and at this time, the convex strip and the base film on the outer side of the pressure roller are in contact, and ... The scraper contacts and squeezes, and the convex strip moves toward the rotating shaft under the action of force, so that the scraper cleans the outside of the cylinder to prevent the residual slurry on the cylinder from affecting the next coating. At the same time, the scraped slurry flows downward along the inclined scraper, enters the guide groove and returns to the interior of the semicircular groove. Filter holes are set on the semicircular groove to prevent impurities from entering the interior of the ink cartridge and causing pollution. A semicircular groove is provided on the outside of the ink cartridge. By setting the semicircular groove, the semicircular groove is prevented from being located below the cylinder, and a filter hole is provided on the inner wall of the semicircular groove.

[0012] Preferably, the pressure roller assembly includes a rotating rod, which is rotatably connected to the bracket, and a pressure roller is fixedly connected to the outer side of the rotating rod. The pressure roller is located above the cylinder, and the motor drives the unwinding roller to rotate. As the base film rotates, the pressure roller is driven to rotate. The base film may deviate during processing, and the base film will contact and be squeezed between the limit blocks on both sides of the pressure roller. The limit blocks are acted upon by the force and move in the direction away from the pressure roller. The inclined side of the outer side of the limit block is squeezed between the protrusion, and the protrusion drives the elastic ring to move in the direction away from the limit block. Under the elastic force of the elastic ring, the protrusion pushes the limit block to reset, thereby resetting the base film on the pressure roller to prevent the base film from deviating and causing The graphene coating is uneven, which affects the heating uniformity and stability of the electric heating film. At the same time, the offset may also cause wrinkles and uneven stretching of the base film, reducing the mechanical strength and service life of the product.

[0015] 2. The fully automatic graphene electric heating film processing equipment increases the tension of the base film by increasing the inclination angle of the fixed plate.

[0034] The drying assembly 5 includes a fixed plate 55, which is rotatably connected to the intervals of the two brackets 1. A shell 57 is fixedly connected to the middle of the top of the fixed plate 55, and rollers 56 are rotatably connected to both ends of the fixed plate 55. The rollers 56 arranged at both ends of the fixed plate 55 can guide the material to run in a straight line along a specific path, which is very important for ensuring that the material does not deviate, twist or fold during the drying process. At the same time, the material may swing during the processing due to airflow, tension changes, etc. The rollers 56 can effectively limit the swing amplitude of the material to keep it in a relatively stable state. The number of rollers 56 There are two rollers 56 symmetrically arranged with the outer shell 57 as the center. A heating plate 58 is fixedly connected to the middle of the inner wall of the outer shell 57. The base film roll is placed on the unwinding roller 8, so that the base film passes through the middle of the pressing roller assembly 4 and the coating assembly 3, and then returns to the winding roller 7 through the drying assembly 5. The motor 6 is connected to an external power supply to work, and the motor 6 drives the unwinding roller 8 to rotate, thereby driving the winding roller 7 to rotate through the transmission member. At this time, the winding roller 7 and the unwinding roller 8 work synchronously, and they can run at the same linear speed to ensure that the material maintains a stable conveying speed throughout the production process, which can avoid material stretching, deformation or accumulation caused by inconsistent speeds. In order to solve the problem, the production efficiency is improved. The base film passes through the drying assembly 5 between the shell 57 and the fixing plate 55. At this time, the heating plate 58 in the middle dries and solidifies the graphene on the surface of the base film, removes the solvent, and forms a stable electric heating film with the graphene powder and the binder. At the same time, the air enters the shell 57 through the side hole on the outside of the shell 57 through the inclined plate 59. The air contacts the heating plate 58. The air carries the heat and moves outward along the connecting plate 510 and the bending plate 511.

The size of the base film tension will affect the uniformity of distribution of the conductive material in the electric heating film, and then affect the uniformity of resistance. When the base film tension is uniform and moderate, the distribution of the conductive material in the electric heating film is more uniform, and the consistency of resistance is better. When the base film tension is large, the electric heating film will be stretched tighter during the drying and curing process. , so that it is easier to maintain a flat state. Appropriate base film tension can keep the electric heating film in a stable size during the drying and curing process. Too much or too little tension may cause the electric heating film to change in size, affecting the accuracy and consistency of the product. When the tension of the base film becomes smaller, the cylinder 513 works to push the slider 52 to move inside the square groove 51, and the slider 52 drives the connecting rod 53 to move toward the direction of the cylinder 513. At this time, under the support of the connecting rod 53, the inclination angle of the fixed plate 55 increases, which increases the tension of the base film. The output end of the cylinder 513 is fixedly connected to the slider 52, and the inner wall side of the shell 57 is fixedly connected to the limiting member 54.

[0041] The base film passes through the drying assembly 5 between the outer shell 57 and the fixed plate 55. At this time, the heating plate 58 in the middle dries and solidifies the graphene on the surface of the base film, removes the solvent, and forms a stable electric heating film with the graphene powder and the binder. At the same time, air enters the inner part of the outer shell 57 through the side holes on the outer side of the outer shell 57 through the inclined plate 59. The air contacts the heating plate 58, and the air carries the heat and moves outward along the connecting plate 510 and the bending plate 511. The evaporation of water in the graphene electric heating film can be accelerated by optimizing the flow of hot air. Rapid evaporation of water can shorten the drying time and improve production efficiency.

[0042] When the tension of the base film becomes smaller, the cylinder 513 works to push the slider 52 to move inside the square groove 51, and the slider 52 drives the connecting rod 53 to move toward the direction of the cylinder 513. At this time, under the support of the connecting rod 53, the inclination angle of the fixed plate 55 increases, so that the tension of the base film becomes larger.
