Auxiliary feeding apparatus of extruder

Abstract

The invention relates to an auxiliary feeding apparatus of an extruder. The apparatus comprises a vertically arranged material cylinder; the upper end of the material cylinder is provided with an end cover; the outside lower end of the material cylinder is provided with an air inlet; a supporting plate laminated to the inner wall is arranged above the air inlet in the material cylinder; the supporting plate is provided with a plurality of uniformly distributed through holes; the center of the end cover is provided with a feeding tube; the upper end of the feeding tube is provided with a discharging tube connected with the feeding tube; one end of the discharging tube is provided with an air pump; and the air inlet is connected with the air pump through an air tube. The air pump allows a material in the material cylinder to be in a floating state and form a negative pressure in the material cylinder, and allows the material to be sucked into the discharging tube and to be discharged through airflow, and the quantity of the fed material can be adjusted, so the work efficiency and the product quality are improved.

Description

technical field [0001] The invention relates to the industrial field, in particular to an auxiliary feeding device for an extruder. Background technique [0002] In the paint industry, some materials cannot be directly put into the feed port of the extruder during the production of the extruder. At this time, it is necessary to use a feeder for feeding, such as Figure 1-2 As shown, the existing feeder includes a vertically placed barrel; the lower end of the barrel is provided with a T-shaped feed pipe and three circumferentially placed supports; the feed pipe is provided with a horizontally placed and rotatable screw rod; One end of the screw is provided with a motor; when working, the material falls into the feeding pipe by its own gravity, and is extruded and put in through the screw in the feeding pipe; in actual work, some materials are very light and cannot be dropped by their own gravity. It is extruded by the screw in the feeding pipe, and the material can only be p...

[0002] In the paint industry, some materials cannot be directly put into the feed port of the extruder during the production of the extruder. At this time, it is necessary to use a feeder for feeding, such as Figure 1-2 As shown, the existing feeder includes a vertically placed barrel; the lower end of the barrel is provided with a T-shaped feed pipe and three circumferentially placed supports; the feed pipe is provided with a horizontally placed and rotatable screw rod; One end of the screw is provided with a motor; when working, the material falls into the feeding pipe by its own gravity, and is extruded and put in through the screw in the feeding pipe; in actual work, some materials are very light and cannot be dropped by their own gravity. It is extruded by the screw in the feeding pipe, and the material can only be put into the extruder manually, which is easy to be inconsistent in proportion and affects the production quality. Therefore, we have developed an auxiliary extruder that can add lighter materials. The feeding device can adjust the quantity of feeding materials, thus improving work efficiency and product quality
