Embodiment 2

[0029] Such as Figure 4 As shown, the difference between the second embodiment and the first embodiment is that the second embodiment does not provide a liquid inlet hole communicating with the cavity, that is, the cavity cannot be filled with liquid, but the rotation pin at both ends of the tension roller is removed from the A shaped hole is provided, and a counterweight is threadedly connected to the discharging end of the rotating pin, so that the counterweight can be replaced.

[0030] According to the thickness and material of the film, when the film needs to have different tensions, by changing different counterweights, the tension rollers can have different qualities, and the tension of the film will be changed accordingly.

Abstract

The invention discloses an extrusion assembly of extrusion equipment, and relates to the field of plastic manufacturing. The extrusion assembly of the extrusion equipment comprises a support, a feeding roller, flattening rollers, an output roller and a driving motor driving the feeding roller and the output roller to rotate. The driving motor is in chain transmission with the feeding roller and the output shaft, the feeding roller is located between the flattening rollers, and the feeding roller and the output roller are located above the flattening rollers. The output roller is arranged on any side of the left side and the right side of the support. The support is fixedly provided with a pair of oppositely-arranged lug plates, the feeding roller and the output roller are rotationally connected with the lug plates, the lug plates are provided with strip-shaped holes, rotating pin shafts matched with the strip-shaped holes are arranged at the two ends of the flattening rollers, the rotating pin shafts are inserted into the corresponding strip-shaped holes, and the flattening rollers can slide up and down relative to the strip-shaped holes. Tensioning rollers are set to be in a floating state, a film is tensioned through self-gravity of the tensioning rollers, the stress of the film is always in a relatively constant state, and thus the tension of the film keeps constant.

Description

Technical field [0001] The invention relates to the field of plastic manufacturing, in particular to an extrusion assembly of an extrusion equipment. Background technique [0002] Plastic film is mainly made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging, and used as a film layer. Plastic packaging and plastic packaging products are taking up more and more shares in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, and food packaging has the largest proportion, such as beverage packaging , Quick-frozen food packaging, steamed food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. In the production process of plastic film, the plastic film after calendering needs to be reeled by the extrusion assembly of the extrusion equipment. When rewinding the plastic film, in order to prevent the film fr...
