Description

Technical Field

[0001] The utility model belongs to the field of galvanizing equipment, and particularly relates to a reciprocating galvanizing device. Background Art

[0002] Galvanized steel wires are mainly used in greenhouse cultivation, farms, cotton bailing, the manufacture of springs and wire ropes. Galvanized steel wires are carbon steel wires galvanized on the surface by hot-dip or electroplating methods. In the existing wire electroplating methods, usually, after the steel wires are unrolled, they pass through an electroplating bath containing galvanizing solution for electroplating. In order to ensure the thickness and quality of the galvanized layer, the electroplating bath is often designed to be very long, resulting in a large occupied area of the galvanizing device and low space utilization rate in the workshop. Content of the Utility Model

[0003] Based on the content in the background art, the utility model discloses a reciprocating galvanizing device, which includes a tank frame, an upper galvanizing tank, a lower galvanizing tank, a traction roller, a passive roller and a driving motor;

[0004] The tank frame has two layers, the upper layer of the tank frame is fixedly installed with an upper galvanizing tank, and the lower layer of the tank frame is fixedly installed with a lower galvanizing tank. A plurality of wire-passing holes are respectively formed in the front and rear side surfaces of the upper galvanizing tank and the front and rear side surfaces of the lower galvanizing tank;

[0005] The traction roller and the passive roller are respectively arranged on the front and rear sides of the upper galvanizing tank and partially placed in the lower galvanizing tank. The traction roller and the passive roller are respectively rotatably connected to the tank frame through bearing seats;

[0006] The traction roller is driven by the driving motor and can rotate along its own rotation axis. Specifically, the driving motor is in transmission connection with the traction roller through a sprocket and a chain, and the driving motor is also fixedly installed on the tank frame. The driving motor is specifically a reduction motor.

[0007] An anode plate is also laid on the bottom of the upper galvanizing tank and the bottom of the lower galvanizing tank. When the steel wire is galvanized, the traction roller and the passive roller serve as cathode rollers. After the steel wire is unrolled and bypasses the traction roller, it enters the upper galvanizing tank through the wire-passing hole in the upper galvanizing tank to contact the galvanizing solution, then comes out from the wire-passing hole behind the upper galvanizing tank, bypasses the passive roller and enters the lower galvanizing tank, contacts the galvanizing solution in the lower galvanizing tank and then bypasses the traction roller again and enters the upper galvanizing tank in the same way. In this way, the steel wire is wound around the traction roller and the passive roller for multiple circles and enters the upper galvanizing tank and the lower galvanizing tank for multiple times, so that the steel wire can be fully electroplated, ensuring the thickness of the galvanized layer and making it have excellent galvanizing quality; with the cooperation mode of components such as the upper galvanizing tank, the lower galvanizing tank, the traction roller and the passive roller, the reciprocating galvanizing device has a small occupied area while ensuring the thickness of the galvanized layer of the steel wire.

[0008] Further, wire dividing rollers are respectively arranged on the front and rear sides of the upper galvanizing tank. The wire dividing rollers are rotatably connected to the tank body frame through bearing seats, and a plurality of annular grooves are formed on the wire dividing rollers. In this way, when the steel wire passes around the traction roller and enters the upper galvanizing tank and after exiting the upper galvanizing tank and passes through the wire dividing rollers, it can be separated by the annular grooves thereon, enabling the steel wire to be evenly distributed and avoiding the situation where the steel wire is entangled and superimposed, which affects the galvanizing quality.

[0009] Further, ceramic pressure rollers are respectively arranged on the front and rear sides inside the upper galvanizing tank, and ceramic supporting rollers are respectively arranged in the middle of the upper galvanizing tank and in the middle of the lower galvanizing tank. Both ends of the ceramic pressure rollers and both ends of the ceramic supporting rollers are respectively rotatably connected to the inner walls of the corresponding galvanizing tanks. The ceramic pressure rollers can press down the steel wire to completely immerse it in the galvanizing solution, while the ceramic supporting rollers can support the steel wire to prevent the steel wire from contacting the bottom surface of the galvanizing tank due to its own weight, which affects the galvanizing quality.

[0010] Through the above technical solutions, the present utility model has at least the following beneficial effects:

[0011] The reciprocating galvanizing device described in the present application has a compact structure and a small floor area. Through the cooperation of components such as the upper galvanizing tank, the lower galvanizing tank, the traction roller and the passive roller, the unwound steel wire can be wound around the traction roller and the passive roller for multiple turns and enter the upper galvanizing tank and the lower galvanizing tank multiple times, enabling the steel wire to be fully electroplated, ensuring the thickness of the galvanized layer, and making it have excellent galvanizing quality. That is, while ensuring the thickness quality of the galvanized layer of the steel wire, the reciprocating galvanizing device has a small floor area, improving the space utilization rate in the workshop.
