Description

Technical Field

[0001] This utility model relates to the field of graphene heating plate processing technology, specifically to a slurry coating device for graphene heating plate processing. Background Technology

[0002] With the rapid development of the new energy and smart home industries, graphene heating panels, due to their advantages such as uniform heating, rapid temperature rise, and low energy consumption, are widely used in indoor heating, medical hot compresses, and industrial insulation, leading to a continuous increase in market demand. In the processing of graphene heating panels, the graphene slurry coating process is the core step that determines product performance. It requires forming a uniformly thick and electrically stable coating on the surface of a metal or insulating substrate. The integrity and consistency of the coating directly affect the heating efficiency and lifespan of the heating panel.

[0003] Currently, most of the slurry coating equipment for graphene heating plates in the industry adopts a single-sided step-by-step spraying process. That is, the slurry is first sprayed on one side of the substrate using a single nozzle or a single-sided nozzle group. After the coating on that side has initially cured, the machine needs to be stopped and the substrate needs to be flipped over manually or mechanically before the other side is sprayed a second time. This seriously restricts production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a slurry coating device for processing graphene heating plates, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slurry coating device for processing graphene heating plates, comprising a worktable, a spraying assembly provided on the side wall of the worktable, the spraying assembly comprising a fixed frame, the fixed frame being fixedly connected to the side wall of the worktable, two sets of symmetrically arranged moving blocks being slidably connected inside the fixed frame, side plates being fixedly connected to the side walls of the moving blocks, a storage box being fixedly connected to the surface of the side plate, a nozzle being fixedly connected to the bottom surface of the side plate, the storage box and the nozzle being interconnected through a conveying pipe, and the two sets of moving blocks being threadedly connected through a bidirectional threaded rod.

[0006] Preferably, the surface of the side plate is provided with a leveling component, the leveling component includes a positioning rod, the positioning rod passes through and is slidably connected to the surface of the side plate, the top end of the positioning rod is fixedly connected to a protrusion, the bottom end of the positioning rod is fixedly connected to a pressure plate, and the bottom end of the pressure plate is fixedly connected to a triangular plate.

[0007] Preferably, the pressure plate and the side plate are elastically connected by a spring.

[0008] Preferably, a motor is fixedly connected to the top of the fixed frame, and the output shaft of the motor passes through and is rotatably connected to the inner wall of the fixed frame and is fixedly connected to the end of the bidirectional threaded rod.

[0009] Preferably, the workbench is equipped with multiple sets of arrayed conveyor rollers inside.

[0010] Preferably, the bottom surface of the workbench is fixedly connected to four sets of symmetrically arranged support legs.

[0011] Compared with the prior art, this utility model provides a slurry coating device for processing graphene heating plates, which has the following beneficial effects:

[0012] 1. This slurry coating device for graphene heating plate processing, through a bidirectional threaded rod and a symmetrical nozzle structure driven by a motor, enables simultaneous double-sided spraying of graphene heating plates. It can complete the coating preparation of the upper and lower surfaces in one go, which not only shortens the spraying time of a single heating plate by more than 100%, but also avoids the problem of double-sided coating misalignment caused by substrate displacement during the flipping process, thus improving processing efficiency and coating position accuracy, and is suitable for mass production scenarios.

[0013] 2. The slurry coating device for processing graphene heating plates uses a triangular plate leveling structure with spring self-adaptive pressure. The spring can automatically adjust the pressure according to the slight undulations on the surface of the heating plate, avoiding substrate deformation or coating damage caused by rigid contact. The positioning rod ensures that the triangular plate always levels along a straight line. With the synergistic effect of the triangular tip and the inclined surface, slurry accumulation is effectively reduced. Attached Figure Description

[0018] like Figures 1-3As shown, this utility model provides a technical solution: a slurry coating device for processing graphene heating plates, including a workbench 1, four sets of symmetrically arranged support legs 11 fixedly connected to the bottom surface of the workbench 1, multiple sets of arrayed conveying rollers 2 arranged inside the workbench 1, and a spraying assembly 3 arranged on the side wall of the workbench 1. The spraying assembly 3 includes a fixed frame 31, which is fixedly connected to the side wall of the workbench 1. Two sets of symmetrically arranged moving blocks 32 are slidably connected inside the fixed frame 31. Side plates 33 are fixedly connected to the side walls of the moving blocks 32. A storage box 34 is fixedly connected to the surface of the side plate 33, and a nozzle 35 is fixedly connected to the bottom surface of the side plate 33. The storage box 34 and the nozzle 35 are interconnected through a conveying pipe 36. The storage box 34 stores graphene slurry and continuously supplies it to the nozzle 35 through the conveying pipe 36. The nozzle 35 atomizes or sprays the slurry onto the surface of the graphene heating plate to form a coating.

[0019] The two sets of moving blocks 32 are threaded together by a bidirectional threaded rod 37. A motor 38 is fixedly connected to the top of the fixed frame 31. The output shaft of the motor 38 passes through and is rotatably connected to the inner wall of the fixed frame 31 and is fixedly connected to the end of the bidirectional threaded rod 37. Driven by the output shaft of the motor 38, the bidirectional threaded rod 37 rotates, driving the two sets of moving blocks 32 to move towards each other or in opposite directions through threaded transmission. This allows the two sets of nozzles 35 to approach the surface and bottom of the side plate 33, achieving double-sided spraying of the graphene heating plate and improving spraying efficiency.

[0020] A leveling assembly 4 is provided on the surface of the side plate 33. The leveling assembly 4 includes a positioning rod 41, which passes through and is slidably connected to the surface of the side plate 33. A protrusion 42 is fixedly connected to the top end of the positioning rod 41, and a pressure plate 43 is fixedly connected to the bottom end of the positioning rod 41. The pressure plate 43 and the side plate 33 are elastically connected by a spring 44. A triangular plate 45 is fixedly connected to the bottom end of the pressure plate 43. The positioning rod 41 restricts the movement direction of the pressure plate 43, allowing only vertical up-and-down movement. The protrusion 42 prevents the positioning rod 41 from slipping off the side plate 33. The spring 44 provides elastic pressure to the pressure plate 43, causing the triangular plate 45 to adhere tightly to the surface of the graphene heating plate. The triangular plate 45, with its triangular tip and bevel, levels the sprayed slurry, controls the coating thickness, and prevents slurry accumulation.

[0021] In this utility model, when in use, the motor 38 at the top of the fixed frame 31 is started. The output shaft of the motor 38 drives the bidirectional threaded rod 37 to rotate. Since the bidirectional threaded rod 37 is threadedly engaged with the two sets of moving blocks 32, the two sets of moving blocks 32 will move synchronously towards or in opposite directions along the internal slide of the fixed frame 31. At the same time, the moving blocks 32 drive the side plate 33 fixed on the side wall, the storage box 34 on the surface of the side plate 33 and the nozzle 35 on the bottom surface to move synchronously until the two sets of nozzles 35 approach the graphene heating plate, and the spray direction of the nozzles 35 is respectively aligned with the upper surface and the lower surface of the heating plate. After the debugging is completed, the motor 38 is turned off.

[0022] Then, an appropriate amount of graphene slurry is injected into the storage tank 34 to ensure that the slurry level meets the requirements for continuous supply. Next, the conveyor roller 2 on the workbench 1 is started, and the conveyor roller 2 smoothly transports the graphene heating plate to be coated to the working area of ​​the spraying component 3.

[0023] When the heating plate moves with the conveying roller 2 to below the nozzle 35, the graphene slurry in the storage box 34 is stably conveyed to the two sets of nozzles 35 through the conveying pipe 36; the nozzles 35 atomize or spray the slurry onto the upper and lower surfaces of the heating plate to form a preliminary double-sided coating, realize synchronous double-sided spraying, shorten the spraying time of a single heating plate, and improve the overall processing efficiency.

[0024] The heated plate, after being sprayed, continues to move with the conveyor roller 2 toward the leveling assembly 4. When the heated plate contacts the triangular plate 45, the leveling assembly 4 on the side plate 33 begins to work: the positioning rod 41 restricts the pressure plate 43 to move only in the vertical direction to prevent the triangular plate 45 from shifting; the spring 44 generates elastic pressure between the pressure plate 43 and the side plate 33, so that the triangular plate 45 fits tightly against the coated surface of the heated plate. Even if there are slight surface undulations of the heated plate, the elastic force of the spring 44 can adaptively adjust the pressure to ensure the fit; as the heated plate continues to move, the triangular tip of the triangular plate 45 first scrapes off the excess paste on the surface to prevent the coating from being too thick or liquid accumulation. Its inclined surface guides the excess paste to fill the depression areas in the coating, and finally forms a flat coating with uniform thickness and no accumulation on the upper and lower surfaces of the heated plate.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
