Punching and waste recovery device for PVC reinforcing rib film production line

Abstract

The invention relates to the field of PVC production equipment, in particular to a punching and waste recovery device for a PVC reinforcing rib film production line. The punching and waste recovery device comprises a punching device and a waste recovery device. The punching device comprises a female cutting roller and a male cutting roller which are matched with each other to form a punching knife, a waste hopper and a discharging hopper are arranged below the female cutting roller and the male cutting roller, the lower end of the discharging hopper is connected with a discharging channel, rotary extrusion rollers which are engaged with each other are arranged in the discharging channel, a fixed cutter and a crushing cutter roller which are matched with each other are arranged below the rotary extrusion rollers, and a material pumping fan is arranged at the lower end of the discharging channel; two waste extrusion rollers are further arranged at the upper end of the discharging channel; the outlet end of the material pumping fan is connected with a cyclone separation barrel through a first pipeline, and a feeding fan is arranged at the lower end of the cyclone separation barrel; and a baffle plate is arranged above the rotary extrusion rollers. According to the device, cut waste materials are recycled, energy is saved, and the requirement for environmental protection is met.

Description

technical field [0001] The invention relates to the field of PVC production equipment, in particular to a punching and waste recycling device for a PVC reinforced fascia production line. Background technique [0002] At present, the market demand for ordinary PVC foam boards in the market is more than 350,000 tons, and the demand for foreign markets is more than 150,000 tons, with a total of more than 500,000 tons. The market share is more than 200,000 tons, and the demand is constantly rising. At present, the high-end plastic sheet market outside mainland China is basically occupied by Japan, South Korea, and Taiwan in Asia, France, Italy, Germany, the United Kingdom in Europe, and the United States in the Americas.

[0002] At present, the market demand for ordinary PVC foam boards in the market is more than 350,000 tons, and the demand for foreign markets is more than 150,000 tons, with a total of more than 500,000 tons. The market share is more than 200,000 tons, and the demand is constantly rising. At present, the high-end plastic sheet market outside mainland China is basically occupied by Japan, South Korea, and Taiwan in Asia, France, Italy, Germany, the United Kingdom in Europe, and the United States in the Americas. Monopoly, some ultra-high molecular precision plastics are absolutely controlled by China. Many plastic products that replace steel plates have been produced in Europe and the United States. However, although China has a large output of plastics and a wide range of uses, most of them are low-end products. There are many types in the market, there are no real high-end ones, only imitation types, which are actually just imitated shapes, and the real performance is actually very poor. As for the surface of the plate covered with acrylic or PET, acrylic sheets can only be pre-produced, and then used The glue sticks the sheet to the board, which increases the process and increases the cost, and it is not environmentally friendly and the lifespan will not last long
