Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment, and in particular to a galvanized roller for metal surface treatment. Background Technology

[0002] In the field of metal surface treatment, galvanizing rollers are important equipment for galvanizing small metal parts. They work by placing the parts inside a roller and depositing a zinc layer on the surface while the roller is rolling, thus achieving galvanized protection for the metal parts. This technology is widely used in many industries, including machinery manufacturing and the automotive industry.

[0003] In existing technologies, the typical method of using galvanizing rollers is as follows: First, the metal parts to be galvanized are pre-treated to remove surface impurities such as oil and rust; then, the parts are placed in the galvanizing roller, which is placed in a galvanizing tank filled with molten zinc; the equipment is turned on to make the roller rotate, and the parts tumble continuously inside the roller, making full contact with the molten zinc. Under the action of an electric field, zinc ions are reduced on the surface of the parts to form a galvanized layer; after galvanizing is completed, the parts are removed for subsequent cleaning, passivation, and other treatments.

[0004] However, bubbles are easily generated during the galvanizing process. These bubbles adhere to the surface of the parts, resulting in uneven zinc coating, with some areas having no coating or inconsistent coating thickness, which seriously affects the quality of galvanizing. To address this issue, a galvanizing roller for metal surface treatment is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a galvanizing roller for metal surface treatment, which aims to solve the problem of difficult-to-eliminate bubbles in the prior art.

[0010] As a further description of the above technical solution: a mounting plate is fixedly connected to the bottom of the motor, and the mounting plate is fixedly connected to the outer wall of the galvanizing tank.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3This utility model provides an embodiment of a galvanizing roller for metal surface treatment, comprising a galvanizing tank 1, a mounting frame 2 fixedly connected to the outer wall of the galvanizing tank 1, and a galvanizing roller 3 rotatably connected to the mounting frame 2 for galvanizing metal parts. A disturbance mechanism 4 is provided on the galvanizing tank 1 to promote the discharge of air bubbles. The disturbance mechanism 4 includes a motor 402, and a cam 403 is fixedly connected to the output end of the motor 402. The operation of the motor 402 can drive the cam 403 to rotate. A hinge plate 404 is hinged to the top outer wall of the galvanizing tank 1 via a hinge seat. The outer wall of the cam 403 contacts the bottom of the hinge plate 404, and the cam 403 can reciprocate under the rotation of the hinge plate 404. A vertical plate 405 is fixedly connected to the bottom of the hinge plate 404. During operation, the vertical plate 405 can impact the liquid in the galvanizing tank 1, thereby generating a certain impact force and vibration, causing the liquid surface to fluctuate and disturb, which can break the surface tension of the bubbles, making it easier for the bubbles attached to the surface of the parts or in the solution to break and detach, thus promoting the expulsion of bubbles above the liquid surface, reducing the presence of bubbles in the galvanizing solution, and reducing the probability of bubbles adhering to the surface of the parts and forming defects. The top of the hinge plate 404 is slidably connected to the connecting rod 407, and one end of the connecting rod 407 is fixedly connected to the cleaning brush 408. It is designed as a fixed connection method that is easy to disassemble, ensuring stability during use and making it easy to disassemble and replace. When the parts move in the solution, the cleaning brush 408 can brush away the bubbles attached to the surface, which is more conducive to the adhesion of the zinc layer and reduces galvanizing defects caused by bubbles.

[0026] Reference Figure 2 - Figure 4 The outer wall of the connecting rod 407 penetrates the inner wall of the vertical plate 405 and is slidably connected to the vertical plate 405. During the sliding of the connecting rod 407, the cleaning brush 408 can be moved. The other end of the connecting rod 407 is fixedly connected to a counterweight 406. The position of the counterweight 406 ensures that the center of gravity of the hinge plate 404 is always close to the cam 403. The counterweight 406 is slidably connected to the top of the hinge plate 404. The displacement of the counterweight 406 can replace the sliding of the connecting rod 407, thereby controlling the position of the cleaning brush 408. The counterweight 406 is threadedly connected to the hinge plate 404 by a bolt rod 409. The bolt rod 409 plays the role of controlling the position of the counterweight 406 and ensuring stability during use. The bottom of the motor 402 is fixedly connected to a mounting plate 401. The mounting plate 401 is fixedly connected to the outer wall of the galvanizing tank 1 and is used to support the motor 402.

[0027] Reference Figure 3 - Figure 5A cooperating mechanism 5 is provided on the galvanizing tank 1. The cooperating mechanism 5 includes a limiting rod 501, which is fixedly connected to the outer wall of the galvanizing tank 1. A movable plate 502 is slidably connected to the outer wall of the limiting rod 501. The movable plate 502 is slidably connected to the limiting rod 501, and has an inclined surface. During the rotation of the cam 403, the inclined surface of the movable plate 502 is intermittently pressed, thereby causing the movable plate 502 to move closer to the galvanizing tank 1. An impact rod 504 is fixedly connected to the bottom of the movable plate 502. The movement of the movable plate 502 can drive the impact rod 504 to strike the galvanizing tank 1, utilizing periodic... The impact generates a shock force, causing a strong instantaneous disturbance in the solution, which helps to break the stability of the bubbles and promotes their rapid rupture and expulsion. A spring 503 is fixedly connected to the outer wall of the galvanizing tank 1. When the movable plate 502 moves towards the galvanizing tank 1, the spring 503 is compressed. After the compression force is lost, the energy stored is released, causing the movable plate 502 to reset. The end of the spring 503 away from the galvanizing tank 1 is fixedly connected to the movable plate 502. A buffer pad 505 is fixedly connected to the outer wall of the galvanizing tank 1. The buffer pad 505 is used to absorb the impact force and reduce damage to the galvanizing tank 1.

[0028] Working principle: After the motor 402 is powered on and started, the output shaft of the motor 402 drives the cam 403 to rotate continuously. Due to the special contour of the cam 403, during the rotation, the outer wall of the cam 403 continuously contacts the bottom of the hinge plate 404 and generates relative motion. When the protruding part of the cam 403 contacts the bottom of the hinge plate 404, it pushes the hinge plate 404 to swing upward around the hinge seat. As the cam 403 continues to rotate, the protruding part moves away, and the hinge plate 404 swings downward under its own weight and the action of the counterweight 406. This realizes the reciprocating swing of the hinge plate 404. During the reciprocating swing of the hinge plate 404, the vertical plate 405 fixed at its bottom moves accordingly. When the vertical plate 405 swings, it impacts the liquid in the galvanizing tank 1. The body causes fluctuations and disturbances on the liquid surface. This disturbance disrupts the surface tension of bubbles, making it easier for bubbles adhering to the surface of the parts or in the solution to break and detach, promoting their discharge above the liquid surface. This reduces the presence of bubbles in the zinc plating solution and lowers the probability of bubbles adhering to the surface of the parts and forming defects. The connecting rod 407, which is slidably connected to the top of the hinge plate 404, has a cleaning brush 408 fixed at one end. This brush moves with the swing of the hinge plate 404. When the parts move in the zinc plating solution, the cleaning brush 408 can brush the surface of the parts, further removing the bubbles adhering to the surface. This promotes more uniform zinc layer adhesion and reduces zinc plating defects caused by bubbles. In addition, the counterweight 406 is slidably connected to the top of the hinge plate 404 and is connected by screws. The bolt 409 is threaded onto the hinge plate 404, allowing adjustment of the position of the counterweight 406, thereby controlling the center of gravity of the hinge plate 404 and ensuring stable swinging of the hinge plate 404. It also adjusts the positions of the connecting rod 407 and the cleaning brush 408. During rotation, the cam 403, in addition to acting on the hinge plate 404, intermittently presses against the inclined surface of the movable plate 502. The movable plate 502 is fitted onto the limiting rod 501 fixed to the outer wall of the galvanizing tank 1 and can slide along the limiting rod 501. When the cam 403 presses against the inclined surface of the movable plate 502, the movable plate 502 overcomes the elastic force of the spring 503 and moves closer to the galvanizing tank 1. The impact rod 504, fixedly connected to the bottom of the movable plate 502, moves along with the movable plate 502. When the movable plate 502 approaches the galvanizing tank 1, the impact rod 504 strikes the galvanizing tank 1. The cam 403 continues to rotate, periodically squeezing the movable plate 502, causing the impact rod 504 to periodically strike the galvanizing tank 1, generating impact force and causing a strong instantaneous disturbance in the solution. This disturbance helps to break the stability of the bubbles, prompting them to break and be expelled quickly. When the cam 403 stops squeezing the movable plate 502, the compressed spring 503 releases its elastic potential energy, driving the movable plate 502 to return to its original position along the limit rod 501 away from the galvanizing tank 1. The buffer pad 505 fixed to the outer wall of the galvanizing tank 1 can absorb most of the impact force when the impact rod 504 strikes the galvanizing tank 1, reducing damage to the galvanizing tank 1 and extending the service life of the equipment.
