Blown film production line auger automatic feeding device

Abstract

The invention relates to an automatic feeding device for an auger in a blown film production line, which includes a storage hopper, and is characterized in that it also includes an auger located in the storage hopper, a motor, and an electronic feedback device for starting material feeding arranged on the hopper of an extruder, The feeding closes the electronic feedback device, the outside of the auger is fixed on the outer wall, the auger sheave is connected to the lower end of the auger, and the motor shaft end is equipped with a motor sheave, and the motor sheave and the auger sheave pass through the transmission belt to form the auger power drive mechanism; The lower end of the auger is equipped with a thrust bearing assembly, and the upper end of the auger is equipped with a self-aligning bearing and a pressure bearing assembly. The advantage is: compared with negative pressure feeding, using the same power motor, only 10 minutes per hour is in the feeding state, saving energy consumption by 75%. Completely avoid dust separation, save raw materials and solve environmental pollution problems; prevent excessive raw material humidity caused by inhalation of excessive moisture, greatly improve the first pass rate of products; and reduce the allocation of human resources through automatic control.

Description

technical field [0001] The invention belongs to plastic film processing machinery, in particular to an auger automatic feeding device for a blown film production line. Background technique [0002] At present, the production process of the feeding process of the known blown film production line requires that the raw materials that have been mixed according to the ratio in the ground storage hopper need to be fed by negative pressure, and the raw materials are sucked through the pipeline by a negative pressure pump and set in the extrusion In the lower hopper on the upper part of the machine. There are the following defects in the process of use: slow feeding, an average of 40 minutes per hour in the feeding state, so that the production energy consumption remains high; part of the dust will be separated from the raw materials during the feeding process, and discharged to the ground or air through pipes In the process, not only the waste of raw materials is caused, but also ...

Problems solved by technology

There are the following defects in the process of use: slow feeding, an average of 40 minutes per hour in the feeding state, so that the production energy consumption remains high; part of the dust will be separated from the raw materials during the feeding process, and discharged to the ground or air through pipes In the process, not only the waste of raw materials is caused, but also the discharged dust pollutes the environment; during the feeding process, the operator needs to manually control the opening or closing of the negative pressure feeding pump through the window of the lower hopper of the extruder; due to the summer air Humidity is high, and long-term suction will mix moisture into the raw materials at the same time, which will cause air bubbles in the product and affect product quality
