[0043] Compared with the prior art, the above technical scheme has the following advantages and positive effects:

[0044] 1. The copper belt conveying mechanism of the traditional special-shaped copper belt cleaning and polishing equipment is easy to scratch or deform the copper belt, greatly increasing the rate of defective products. The present application designs a special-shaped copper belt cleaning and polishing equipment, in which the copper belt conveying mechanism is designed as a push-pull type conveying mechanism with two groups of front and rear rollers, the rotation speed of the front and rear roller driving wheels is different, the rotation speed of the rear copper belt conveying mechanism driving wheel is K times that of the front copper belt conveying mechanism driving wheel, and the value of K is obtained according to actual experiments. The present application ensures the tensile state of the copper belt and does not damage the copper belt.

[0045] 2. The rollers of the copper belt conveying mechanism in the present application are made of silica gel, which ensures that there is a large friction force between the copper belt and the rollers, increases the driving force of the conveying mechanism, and ensures that the copper belt does not deform under the premise of a large force between the rollers and the copper belt.

[0046] 3. The copper belt polishing mechanism of the traditional special-shaped copper belt cleaning and polishing equipment is fixed and cannot be adjusted, and once the polishing body is worn out, it needs to be replaced in time, which affects the work efficiency and wastes resources. The present application designs an adjustable polishing mechanism, which can change the position of the polishing body relative to the copper belt by rotating the adjusting shaft, so that the copper belt polishing precision can be adjusted and the polishing mechanism can be replaced, and the work efficiency is improved.

[0047] 4.

This patent application designs a polishing oil recycling method, with spray-type oil supply above the irregular-shaped copper strip and immersion-type oil supply below, making the equipment easy to install and providing sufficient and even oil supply.

[0048] 5. Traditional non-circular copper strip cleaning and polishing equipment uses a single-piece polishing oil tank design. When replacement is needed, all the polishing oil must be replaced, resulting in significant resource waste. The polishing oil tank designed in this patent application is multi-compartmental. Replacement only requires changing the polishing oil in the compartment that needs replacing. The compartmentalized design allows for the settling of polishing waste of different particle sizes, improving the utilization rate of the polishing oil.

[0049] 6. This patent provides a cleaning and polishing equipment for irregularly shaped copper strips. It adopts a modular design, has strong expandability, is easy to install and maintain, and has great market value in the field of automatic cleaning and polishing of irregularly shaped copper strips.

[0050] 7.
