Description

Technical Field

[0001] The invention belongs to the technical field of feeding equipment, and in particular relates to a movable EVA raw material automatic centralized feeding gantry vehicle device. Background Art

[0002] If solar cells are directly exposed to the air, their photoelectric conversion efficiency will drop quickly and lose their practical value. In order to achieve the purpose of isolation from the outside world, it is necessary to use transparent, light-resistant, good bonding performance, able to withstand atmospheric changes and elastic ethylene-vinyl acetate copolymer (EVA) film to encapsulate the solar cell and bond it with the upper and lower protective materials to form a solar cell module.

[0003] The main process of EVA film includes liquid preparation, mixing, extrusion, shaping, slitting, packaging, etc. The mixing process is particularly important. EVA particles and cross-linking agents, auxiliary cross-linking agents, silane coupling agents, light stabilizers and other additives need to be put into the batching kettle in a certain proportion and mixed evenly. Stir at a temperature of 40°C for 4 hours to make dry resin particles.

[0004] At present, there are two main ways to add EVA particles. One is to manually unstack and break the bags, and pour them directly into the mixing kettle from the feeding port on the second floor. Generally, there are two types of EVA stacking packages, 40 bags per pallet and 60 bags per pallet, each bag is 25 kg. Workers have to move down bags one by one, break the bags and pour them into the mixing kettle. This method is very labor-intensive. The other is to manually unstack and break the bags, pour them into stainless steel containers, and then use pneumatic conveying to pump them into the mixing kettle. The feeding time of these two methods is usually more than one hour, which will occupy the mixing time of the mixing kettle, resulting in low work efficiency, and high labor intensity. The pneumatic conveying method will also produce a certain amount of broken powder, affecting the quality of the product. Summary of the invention
