Plastic film production device and process thereof

Abstract

The invention discloses a plastic film production device and a process thereof. The production device comprises a machine frame with a hollow structure, a blow molding machine head is installed at theinner center of the frame, a limiting mechanism, an air extraction device, a herringbone plate and a traction device are sequentially arranged on the machine frame above the blow molding machine headaccording to the process of plastic film forming, a movable and adjustable counting device is arranged on the traction device, a cutting device and a winding device are sequentially arranged on the outer side ground of the machine frame at the output end of the traction device, and the winding device further comprises a film breaking device. The process comprises the following steps of (1) extruding molding of a plastic film; (2) setting and exhausting; (3) clamping flattening and pressing; (4) cutting and layering; and (5) winding and packing. According to the plastic film production deviceand the process thereof, through the improvement of the process equipment, in the production process, limiting is conducted on the plastic film protect the plastic film from being scratched, the volatile waste gas of the production plastic film is exhausted, the environment is protected, the length of the plastic film is accurately measured, accurate cutting and breaking of the plastic film are achieved, the plastic film production device is suitable for the production of plastic films of various specifications, and the production efficiency and product quality are improved.

Description

technical field [0001] The invention relates to the field of plastic film production, in particular to a plastic film production device and a process thereof. Background technique [0002] With the advancement of human science and technology, agricultural development has gradually stepped into the track of developing agriculture through science and technology. Agricultural planting is not only aimed at food, but more and more economic crops are developed. The use of mulch film has a huge demand for film, and the production of mulch film generally adopts flat extrusion. The blow molding of the blow molding method, in the molding process, first the raw materials are melted and plasticized in the extruder of the blow molding machine, and then the molten raw materials are extruded through the blow molding machine head of the blow molding equipment to form a thin-walled tube. Then, compressed air is sprayed out through the mandrel of the machine head to inflate the thin-walled tu...
