Plastic film blowing system with reheating function

Abstract

The invention discloses a plastic film blowing system with a reheating function. The plastic film blowing system involves a raw material drying device and a film blowing device, wherein plastic raw material dried by the raw material drying device is manually fed into a storage hopper of the film blowing device; the raw material drying device comprises a drying housing, wherein the bottom wall of the drying housing is fixedly connected with a reheating cylinder, a stirring motor is fixedly connected to the upper end of the reheating cylinder, and an output shaft of the stirring motor is fixedlyconnected with a stirring block through a folding rod; an electric material falling door is formed in the bottom wall of the drying housing, an electric heater is fixedly connected in the reheating cylinder, the upper end of the electric heater is in communication with an outlet of a suction fan through an air inlet pipe of the heater, an inlet of the suction fan is in communication with an outlet of an activated carbon box, multiple layers of honeycomb activated carbon layers are arranged in the activated carbon box, an inlet air pipe of the activated carbon box is provided with an opening located at the surface of the reheating cylinder, and an outlet pipe of the electric heater is in communication with a plurality of branched spray pipes; and a material falling housing is arranged below the drying housing, a gate plate door is arranged at the bottom of the material falling housing, and a material collecting barrel with an opening in the upper end is placed below the gate plate door.

Description

technical field [0001] The invention relates to the technical field of film blowing equipment, in particular to a plastic film blowing system with reheating function. Background technique [0002] The film blowing machine is a kind of film production automation equipment. The film blowing machine mainly heats and melts the plastic particles and then blows them into a film. Expanding herringbone board, traction roller, coiling to roll the finished film into a tube, suitable for blowing low-density polyethylene, high-density polyethylene and linear low-density plastic films, widely used in fruit, food, clothing, textiles, Internal and external packaging of civil and industrial products such as strain cultivation and daily necessities; [0003] Before the plastic raw material is melted, it needs to be dried by hot air to ensure the effect of melting. The existing raw material drying devices basically use one of static or dynamic drying, and the hot air is directly discharged ...

AI Technical Summary

Problems solved by technology

The existing raw material drying devices basically use one of static or dynamic drying, and the hot air is directly discharged as exhaust gas after being used only once, and the energy utilization rate is low; at the same time, the current film blowing device produces The exhaust gas is directly discharged into the atmosphere, which is easy to cause harm to the operator's body and pollute the environment
