Description

Technical Field

[0001] The utility model relates to a plate production device, in particular to an automatic batching and feeding device for aluminum-plastic plates. Background Art

[0002] As a new type of decorative material with excellent performance, as aluminum-plastic composite panels have been more and more widely used in various industries today, the demand for aluminum-plastic panels has increased greatly, which has put forward higher requirements on the production capacity of aluminum-plastic composite panel production lines.

[0003] Another major outstanding contribution of aluminum-plastic panels is that the white pollution of plastics that people worry about has not occurred. Aluminum-plastic panels have played an indispensable role. Why? Because the production of aluminum-plastic panels in China mostly uses recycled plastics. Since the price of recycled plastics is relatively high, driven by interests, China's recycled plastics industry and aluminum-plastic panels have developed simultaneously. It can be said that if there is no such a large industry of recycled plastics as aluminum-plastic panels, waste plastics will have no practical value, and the white pollution predicted by experts will really appear. Since the aluminum-plastic panel industry consumes most of the recycled plastics, no white pollution is generated. Then the question is, recycling plastics to make aluminum-plastic panels, the classification of recycled plastics is very important, the sources of various recycled plastics are different, and their performance gaps are also very large, such as the recycled materials of white plastic bags and the hard plastics of ordinary plastic containers such as buckets and mineral water bottles, their performance differences are very large, and the molding process parameters are also different. In addition, there are many grades of recycled plastics. According to the different quality requirements of aluminum-plastic panels, some new plastic particles should also be mixed in them. In this way, each aluminum-plastic panel factory will have many kinds of formulas. For example, our company has 21 formulas. The traditional process in the existing technology is to use a forklift to send different recycled plastics and new materials to the mixer according to the process requirements. Mix and mix, and then use a forklift to pour them into the silo of the aluminum-plastic panel production line through the elevator. Since these processes are open, and there is a lot of dust on the surface when the recycled plastics are crushed, the environment in the workshop is quite dirty and messy. The dust filled the workshop also affects the health of the workers, and the work efficiency is also very low. Utility Model Content
