A copper strip surface coating device

Abstract

This utility model relates to the field of copper strip surface coating technology, specifically a copper strip surface coating device. The device includes two unwinding shaft bases and two flattening roller bases. Three flattening rollers are rotatably connected to the two flattening roller bases on their adjacent sides. When the film shifts laterally, the connecting plate is moved to a specified height via the telescopic end of an electric telescopic rod. Then, the mounting frame is rotated to a specified angle via the output end of a first rotating motor, making the bottom surface of the second arc-shaped block parallel to the plane of the film. The output end of the second rotating motor then drives the first arc-shaped block to rotate, which in turn drives the second arc-shaped block to rotate. When the bottom end of the second arc-shaped block contacts the film, the film abuts against the flattening rollers. The friction of the friction blocks causes the film to adjust laterally, returning it to its initial position for transport, thus facilitating the coating of the copper strip.

Description

Technical Field

[0001] This utility model relates to the field of copper strip surface coating technology, specifically a copper strip surface coating device. Background Technology

[0002] In the copper alloy strip manufacturing industry, copper strip is typically transported in coils. Current transportation methods usually involve land transport. During transit, vehicle vibrations and bumps can cause relative displacement and friction between the layers of the coil, leading to friction corrosion on the product surface. Hot-dip tin-plated products are particularly susceptible to friction corrosion due to the low hardness of their tin plating layer. In areas of friction corrosion on the copper strip surface, the metal undergoes oxidation, increasing the contact resistance at those locations and rendering the product unusable upon delivery to the customer.

[0003] Patent publication number CN222987573U discloses a cross-cutting and coating device for copper and copper alloy strips, including copper strip, unwinding assembly, tensioning mechanism, plastic film, conveying assembly, flattening and adjusting assembly and coating assembly.

[0004] To address the problem of wrinkles and ripples in existing coating devices due to the lack of tensioning and flattening rollers, current technology involves modifying the tensioning mechanism and flattening adjustment components to form an integrated copper and copper alloy strip cross-cutting coating device. This avoids wrinkles and ripples during the cross-cutting coating process. However, the existing flattening rollers are affected by processing, making it difficult to achieve perfectly consistent circumferential surface dimensions. During actual coating, the rotation of the flattening rollers can cause lateral displacement of the film, leading to inconvenience in copper strip coating. Therefore, we propose a copper strip surface coating device. Utility Model Content

[0005] The purpose of this invention is to provide a copper strip surface coating device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions: A copper strip surface coating device includes two unwinding shaft bases and two flattening roller bases. The two unwinding shaft bases are rotatably connected to an unwinding shaft on their adjacent sides, and the two flattening roller bases are rotatably connected to three flattening rollers on their adjacent sides.

[0007] The bottom of each of the two flattening roller bases is fixedly connected to a mounting plate, and a sliding connecting plate is provided above each of the two mounting plates. An adjustment mechanism is provided between the two connecting plates.

[0008] The adjustment mechanism includes two support plates fixedly connected to the top surfaces of two connecting plates respectively. A rotatable mounting frame is provided on one side wall of the two support plates that are close to each other. A second rotating motor is fixedly installed in the inner cavity of the mounting frame. The output end of the second rotating motor passes through the wall plate of the mounting frame and is fixedly connected to a first arc-shaped block. A second arc-shaped block is provided below the first arc-shaped block. Multiple friction blocks are fixedly connected to the bottom surface of the second arc-shaped block. Three springs are fixedly connected to the bottom surface of the first arc-shaped block and the top surface of the second arc-shaped block. Each of the three springs has a telescopic rod in its inner coil.

[0009] Preferably, an electric telescopic rod is fixedly installed on the top surface of each of the two mounting plates, and the telescopic ends of the two electric telescopic rods are respectively fixedly connected to the bottom surface of the two connecting plates.

[0010] Preferably, a support base is fixedly connected to the top surface of one of the connecting plates, and a first rotating motor is fixedly installed on the top surface of the support base.

[0011] Preferably, each of the two support plates has a round rod rotatably connected to one of their adjacent side walls, and the two round rods are rotatably connected to the two side walls of the mounting frame, respectively. The output end of the first rotating motor passes through the wall of one of the support plates and is fixedly connected to the end of one of the round rods.

[0012] Preferably, the telescopic ends of the three telescopic rods are all fixedly connected to the bottom surface of the first arc-shaped block, and the bottom ends of the three telescopic rods are all fixedly connected to the top surface of the second arc-shaped block.

[0013] Preferably, the bottom surface of the second arc-shaped block is arc-shaped, and the plurality of friction blocks are arranged equidistantly on the bottom surface of the second arc-shaped block. The three springs and telescopic rods are also arranged equidistantly on the bottom surface of the second arc-shaped block, corresponding to the arc of the bottom surface.

[0014] Preferably, the three flattening rollers are arranged in a triangular shape on the base of the two flattening rollers.

[0015] The beneficial effects of this utility model are: This invention utilizes a second rotating motor, a second arc-shaped block, and a friction block. After the film undergoes lateral displacement, the connecting plate is moved to a specified height via the telescopic end of the electric telescopic rod. Then, the mounting frame is rotated to a specified angle via the output end of the first rotating motor, making the bottom surface of the second arc-shaped block parallel to the plane of the film. The output end of the second rotating motor then drives the first arc-shaped block to rotate, which in turn drives the second arc-shaped block to rotate. When the bottom end of the second arc-shaped block contacts the film, the film abuts against the flattening roller. Due to the friction force of the friction block, the film undergoes lateral adjustment, returning to its initial position for conveying. This facilitates the coating of copper strips. Simultaneously, the contraction of the spring and telescopic rod prevents excessive contact stress between the friction block and the film from causing damage. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4As shown, a copper strip surface coating device includes: two unwinding shaft bases 1 and two flattening roller bases 3. The two unwinding shaft bases 1 are rotatably connected to an unwinding shaft 2 on their adjacent sides. The two flattening roller bases 3 are rotatably connected to three flattening rollers 4 on their adjacent sides. Mounting plates 5 are fixedly connected to the bottom of each of the two flattening roller bases 3. Sliding connecting plates 7 are provided above each of the two mounting plates 5. An adjustment mechanism 8 is provided between the two connecting plates 7. The adjustment mechanism 8 includes two support plates 83 fixedly connected to the top surfaces of the two connecting plates 7 respectively. Electric telescopic rods 6 are fixedly installed on the top surfaces of the two mounting plates 5. The telescopic ends of the two electric telescopic rods 6 are fixedly connected to the bottom surfaces of the two connecting plates 7 respectively. The three flattening rollers 4 are triangularly arranged on the two flattening roller bases 3.

[0020] In practice, the unwinding shaft base 1 and the flattening roller base 3 are fixed on the slitting machine or winding machine using the mounting plate 5 and the flattening roller base 3. The unwinding shaft 2 is parallel to the top of the machine, and the flattening roller 4 is parallel to the horizontal direction of the machine. During production, a film is added to the unwinding shaft 2. The film is unwound to the flattening roller 4 by the external drive motor of the unwinding shaft 2 and adheres to the surface of the copper strip. The flattening roller 4 squeezes out the air between the film and the copper strip, and the plastic film adheres tightly to the surface of the copper strip.

[0021] As a technical optimization of this utility model, a rotatable mounting frame 85 is provided on one side wall of the two support plates 83 that are close to each other. A second rotating motor 86 is fixedly installed in the inner cavity of the mounting frame 85. The output end of the second rotating motor 86 passes through the wall plate of the mounting frame 85 and is fixedly connected to a first arc-shaped block 87. A second arc-shaped block 801 is provided below the first arc-shaped block 87. Multiple friction blocks 802 are fixedly connected to the bottom surface of the second arc-shaped block 801. Three springs 88 are fixedly connected to the bottom surface of the first arc-shaped block 87 and the top surface of the second arc-shaped block 801. Each of the three springs 88 has a telescopic rod 89 in its inner ring. A support base 81 is fixedly connected to the top surface of one of the connecting plates 7. The first rotating motor is fixedly installed on the top surface of the support base 81. 82. Two support plates 83 are rotatably connected to one side wall of each other. The two round rods 84 are rotatably connected to the two side walls of the mounting frame 85 respectively. The output end of the first rotating motor 82 passes through the wall of one of the support plates 83 and is fixedly connected to the end of one of the round rods 84. The telescopic ends of the three telescopic rods 89 are fixedly connected to the bottom surface of the first arc-shaped block 87. The bottom ends of the three telescopic rods 89 are fixedly connected to the top surface of the second arc-shaped block 801. The bottom surface of the second arc-shaped block 801 is arc-shaped. Multiple friction blocks 802 are circumferentially and equidistantly arranged on the bottom surface of the second arc-shaped block 801. The three springs 88 and the telescopic rods 89 are also circumferentially and equidistantly arranged according to the arc of the bottom surface of the second arc-shaped block 801.

[0022] In practice, when the flattening roller 4 rotates for a long time, the unevenness of the surface of the flattening roller 4 will cause the film to shift laterally. The electric telescopic rod 6 is activated, and the connecting plate 7 is moved to a specified height through the telescopic end of the electric telescopic rod 6. Then, the first rotating motor 82 is activated, and the mounting frame 85 is rotated to a specified angle through the output end of the first rotating motor 82, so that the bottom surface of the second arc block 801 is parallel to the plane of the film. The second rotating motor 86 is activated, and the first arc block 87 is rotated through the output end of the second rotating motor 86. The rotation of the first arc block 87 causes the second arc block 801 to rotate. When the bottom end of the second arc block 801 contacts the film, the film abuts against the flattening roller 4. Under the influence of the friction force of the friction block 802, the film will be laterally adjusted, allowing the film to return to its initial position for conveying, thereby facilitating the coating of the copper strip. By utilizing the contraction of spring 88 and telescopic rod 89, excessive contact force between friction block 802 and the film can be prevented from causing damage to the film.

[0023] In use, this invention utilizes the mounting plate 5 and the flattening roller base 3 to fix the unwinding shaft base 1 and the flattening roller base 3 onto the slitting machine or winding machine. The unwinding shaft 2 is parallel to the top of the machine, and the flattening roller 4 is parallel to the horizontal direction of the machine. During production, a film is attached to the unwinding shaft 2. An external drive motor connected to the unwinding shaft 2 drives the film to be unwound onto the flattening roller 4, where it adheres to the surface of the copper strip. The flattening roller 4 squeezes out the air between the film and the copper strip, causing the plastic film to adhere tightly to the surface of the copper strip. When the film shifts laterally, the electric telescopic rod 6 is activated. The telescopic end of the electric telescopic rod 6 moves the connecting plate 7 to a designated height. Then, the first rotating motor 82 is started, and the mounting frame 85 is rotated to a specified angle through the output end of the first rotating motor 82, so that the bottom surface of the second arc block 801 is parallel to the plane of the film. The second rotating motor 86 is started, and the first arc block 87 is rotated through the output end of the second rotating motor 86. The rotation of the first arc block 87 drives the second arc block 801 to rotate. When the bottom end of the second arc block 801 contacts the film, the film abuts against the flattening roller 4. Under the influence of the friction force of the friction block 802, the film will be driven to make lateral adjustment, so that the film returns to its initial position for conveying and coating the copper strip.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
