Separation and heating crushing machine

Abstract

The invention discloses a separation and heating crushing machine. The separation and heating crushing machine comprises a machine body, wherein a feeding opening A is formed in the upper end of the machine body, a discharging opening is formed in the lower end of the machine body, a crushing chamber is arranged in the machine body, a blending device is arranged in the crushing chamber, and comprises a fixed screw rod and a crushing screw rod, the fixed screw rod is provided with a spiral cutter blade A, the crushing screw rod is provided with a spiral cutter blade B, the spiral cutter blade A and the spiral cutter blade B are arranged in a staggering manner, and a filter net is arranged in a lower end opening of the crushing chamber. A feeding opening B is also formed in the machine body, the lower end of the feeding opening A is connected with a guide pipe A, the feeding opening B is connected with a guide pipe B, the guide pipe A is connected with the guide pipe B, a protrusion end is arranged on one end, adjacent to the feeding opening A, of the guide pipe A, the bottom of the guide pipe A is provided with a piston block, and a projection is arranged on the position, adjacent to the protrusion end, in the guide pipe A. By adopting the separation and heating crushing machine, the plastics can be molten by utilizing hot air, and the molten plastics can enter the crushing chamber to be crushed only at a specified temperature, so that the abrasion of a crushing cutter can be alleviated.

Description

technical field [0001] The invention relates to a cutting device, which belongs to the technical field of pulverizers, in particular to a pulverizer for separation and heating. Background technique [0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging, and as a laminate. With the development of the economy and the adjustment of the rural industrial structure, the market demand for plastic films in various industries in China continues to rise, and the share of plastic packaging and plastic packaging products in the market is increasing, especially composite plastic flexible packaging. Widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great benefits to people's lives. convenience.

Problems solved by technology

The plastic shredder of the invention drives the cutter shaft to rotate through the motor, so that when the waste plastics are put into the crushing bin, the cutting of the waste plastics by the cutter is realized, but the crushing The machine only cuts the plastic once, and there is still uneven cutting after cutting, and the crushing effect is poor.
