Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic glass plate processing, and specifically relates to an EVA coil shearing mechanism. Background Art

[0002] Photovoltaic glass, as an important component of photovoltaic modules, is mainly used to encapsulate and protect solar panels. Its core properties include high light transmittance, high strength and strong corrosion resistance. Ultra-white glass has become the preferred material for manufacturing photovoltaic glass due to its excellent light transmittance. According to different manufacturing processes and application scenarios, photovoltaic glass can be divided into ultra-white rolled glass and ultra-white float glass, among which ultra-white rolled glass occupies a dominant position in the market.

[0003] During the preparation process of photovoltaic glass, it is necessary to lay EVA strips on the photovoltaic glass plate and complete the welding process. The working process is usually that after the glass raw materials are transported to the EVA strip laying and welding machine, the correction welding mechanism of the EVA strip laying and welding machine will straighten the glass, and then the EVA coil will be fed through the loading roller of the EVA strip laying and welding machine, and the EVA strips will be formed into EVA strips after shearing and punching by the shearing mechanism and punching mechanism and stored on the strip carrier. The strips will be transplanted to the corresponding position of the glass raw materials by a transplanting robot, and finally welded and fixed by the correction welding mechanism. After completing the above processes, the glass plate will be transported to the next sub-process.

[0004] When the above-mentioned existing shearing mechanism is working, it is usually cut directly by a bevel cutter after the EVA coil is unwound in the coil drum. When the bevel cutter is used for cutting, the EVA coil usually needs to be tightened before it can be cut easily. However, it is difficult to ensure that the EVA coil is completely tightened after being unwound in the coil drum. This makes the bevel cutter's cutting edge uneven during cutting. In addition, the bevel cutter is set according to the length of the coil during use, so the bevel cutter is long, the installation and debugging are cumbersome, the maintenance and care costs are high, and the service life is short. In view of this, the utility model provides an EVA coil shearing mechanism. Utility Model Content
