Plastic film blowing machine

Abstract

The invention discloses a plastic film blowing machine. The plastic film blowing machine comprises a slow flow particle hopper, a main body machine box, a control box, a conveying table top, a support, a buckle rod, roller wheels and a conveying bearing platform, the bottom of a speed regulation particle hopper is connected with the main body machine box, the conveying bearing platform is connected with the slow flow particle hopper through the main body machine box, the main body machine box is connected with the conveying bearing platform 8, the conveying table top is arranged on the conveying bearing platform, the bottom of the main body machine box is connected with the top of the support, the roller wheels are arranged at the bottom of the support, materials are cushioned from a cushioning sliding surface and enter the slow flow disc for first-step flow distribution, material particles fall down from a slow flow hole by rotating and sweeping of a sweeping rod, the slow flow disc serves as a secondary flow distribution, the number of the slow flow holes of the slow flow disc is different, the secondary flow distribution is also different, the secondary flow distribution and discharging speeds are controlled through two times of flow distribution, so that discharging is stable, blockage is not easy to occur, the particles are heated and ground more sufficiently, and the film blowing quality is improved.

Description

technical field [0001] The invention is a plastic film blowing machine, which belongs to the field of machinery. Background technique [0002] The film blowing machine heats and melts plastic particles and blows them into films. There are many types of film blowing machines, such as PE, POF, PVC and so on. The new material is blown out with brand-new particles, the color is uniform, clean, and the bag stretches well. [0003] The prior art discloses a plastic film blowing machine whose application number is CN201620477871.7. Its structure includes a frame, an extrusion cylinder, a blown film die, a high-pressure air pump and a film collection mechanism, an extrusion cylinder, and a blown film die. , high-pressure air pump and film winding mechanism are all installed on the frame, and the end of the film blowing die is connected to the extrusion barrel. However, this prior art controls the blanking of the film blowing machine, and it is easy to be unstable due to the rate of...
