Description

Technical Field

[0001] The utility model relates to a plate production device, in particular to an aluminum-plastic plate production device. Background Art

[0002] Aluminum-plastic composite panels are a new type of decorative material with a series of excellent properties. Since the product was invented in the United States in the 1960s, it has been widely used in the fields of curtain wall interior and exterior decoration, creating a new era in the contemporary architectural decoration industry. After entering the 21st century, with the continuous development of my country's economy and the prosperity of the construction market, aluminum-plastic composite panels have been initially recognized in my country, and the market and production technology of aluminum-plastic composite panels are also constantly maturing. The output is increasing every year.

[0003] As the production of aluminum-plastic panels continues to expand, people's requirements for production efficiency are getting higher and higher. Figure 1 As shown, during the production of aluminum-plastic panels, in order to ensure that there are no defects, the plastic is generally 5 to 10 mm wider than the upper and lower skin aluminum plates when the aluminum-plastic panels are extruded. When compounding with the aluminum plate, the excess plastic edge strip waste 1 needs to be cut off close to the edge of the aluminum plate. This production method can ensure that the aluminum-plastic panel plastic is full and has no cavities. The aluminum-plastic panel production line has a very fast compounding speed, which is 8 to 16 meters per minute. The thinnest plastic of the aluminum-plastic panel is 3 mm, generally 3 to 4 mm, and the cutting width of each side of the plastic is 5 to 10 mm. Therefore, the weight of recycled plastic on the production line every minute is:

[0004] G=v×ρ

[0005] In the formula, G represents weight, v represents plastic volume, and ρ represents plastic density = 1.1 g / cm3.

[0006] Volume v = b × h × S

[0007] In the formula, v represents the volume of plastic, b represents the width of plastic, h represents the thickness of plastic, and s represents the speed of aluminum-plastic composite. Then the trimming material per minute is:

[0008] Volume V = (2 × 0.7) cm × 0.35 cm × 1000 cm / min × 1 min = 490 cm 3

[0009] Weight G = 490 cm 3 ×1.1 g / cm 3 =539g

[0010] That means about 0.5 kg of plastic waste is produced on both sides every minute, which is 30 kg per hour.

[0011] At present, the waste treatment on the production line still uses manual handling. The wrapped and bundled edge strip waste 2 needs to be manually transported to the crusher. However, due to manual handling, the recycled waste cannot be wrapped too much, otherwise it is inconvenient to carry. After being manually transported to the plastic recycling station, the recycling station will crush it again, and then transport it to the feed mixer again after crushing. In the process of crushing and transporting again, a certain amount of dust will be generated, affecting the production environment. Therefore, in the prior art, generally 1-2 workers must be equipped on the production line to carry the plastic waste edges. It is both time-consuming and labor-intensive, and affects the environment. Utility Model Content

[0012] The technical problem to be solved by the utility model is to provide an automatic recycling device for plastic edge materials of an aluminum-plastic plate production line, which realizes the automatic crushing, recycling and feeding of plastic edge strip waste, greatly improves the environment of the production workshop, saves labor, reduces costs, and improves the core competitiveness of the enterprise.

It can be applied to the existing aluminum-plastic panel production line, perfectly compatible with and upgrades the existing production line equipment, and improves the core competitiveness of the enterprise.

[0023] In addition, the use of this automatic recycling device is also helpful in improving product quality. If the plastic waste edges are not cleaned up in time, they will swing around and affect the composite quality.

[0024] Since the entire transportation process is carried out in a sealed pipeline, dust pollution will not be generated and impurities that affect the quality of the plastic waste will not be mixed into the transportation process. BRIEF DESCRIPTION OF THE DRAWINGS
