Raw material stirring equipment for plastic film production

Abstract

The invention discloses raw material stirring equipment for plastic film production, and relates to the technical field of plastic film production, the raw material stirring equipment comprises a rack, a film discharge mechanism is fixedly arranged on the rack, a crushing cylinder is fixedly arranged at the top of the film discharge mechanism, and a particle crushing mechanism is arranged at the top of the crushing cylinder; the particle crushing mechanism is arranged on the machine frame in a lifting mode, a film rolling mechanism is arranged at the bottom of the film discharging mechanism, adjustable shielding air collecting mechanisms are arranged on two air expanding barrels in the film rolling mechanism, and a limiting and re-cooling mechanism is arranged on the rear side of the machine frame. While secondary cooling is carried out on a film, scraping between the film and the air expansion barrel can be avoided, the film quality is further guaranteed, meanwhile, the temperature is further reduced when the film is discharged, a technician can conveniently wind or transfer the film, in addition, air waste can be avoided, energy is saved, and the device is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of plastic film production, in particular to a raw material stirring device used for plastic film production. Background technique [0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins for plastic films are used for packaging and as a coating layer. During the production process of plastic films, the raw materials need to be fully stirred by a mixer , to ensure the quality of subsequent finished products. [0003] The invention patent of Patent Application Publication No. CN 110901112 B discloses a plastic film, a processing system and a processing technique. The raw materials in the plastic film include 35 parts of waste plastic, 24 parts of glass fiber, 21 parts of polylactic acid, 16 parts of ethylene terephthalate, 4 parts of curing agent, 8 parts of plasticizer and 13 parts of binder. The process is: 1. Put the plastic particles into the raw material extr...

Problems solved by technology

[0004] However, the above-mentioned device still has some shortcomings in actual use. The more obvious ones are that it uses two air expanders to cool the rolled film, and at the same time uses the conveyor frame to output the cooled and formed plastic film. During the process, when the conveyor rack outputs the plastic film, it will pull the film to be cooled between the two air diffusers, and then make it biased towards the air expander close to the output position. At this time, the plastic film after cooling It is very easy to rub against the lower edge of the air diffuser, which will cause scratches on the surface of the film and affect the quality of its finished product

[0005] Although the method of using two expansion tubes at the same time can cool down the film, due to the limitation of the height of the device, the actual heat exchange time of the plastic film is too short, which is enough to ensure the molding, but it still maintains a relatively high temperature during subsequent output. , so it is inconvenient for technicians to rewind or transfer it

[0006] In addition, in order to adapt to the production of films with different widths, the width of the air diffuser will be larger than the width of the film, which will cause the wind blown from the edge of the air expander to be unable to exchange heat with the film, resulting in a waste of air volume
