Feeding hopper of extruding machine

Abstract

The invention discloses a feeding hopper of an extruding machine. The feeding hopper comprises a hopper body, wherein the hopper body comprises an inverted-cone-shaped storing section and an annular discharging section; the storing section and the discharging section are coaxially arranged; the top of the storing section is provided with a cover plate, the cover plate is provided with a feed port, and the top of the cover plate is provided with a driving motor; the driving motor is connected with a main shaft which is arranged in a manner of stretching into the hopper body, the main shaft is provided with multiple groups of loose blade structures at intervals, the loose blade structures are positioned in the storing section, and each loose blade structure comprises at least four loose blades which are uniformly distributed in an annular manner, and each loose blade is arranged in an inclined manner; the blade surface of each loose blade is arranged in a manner of facing the rotating direction of the main shaft, the tail end of the main shaft is provided with a helical blade, and the helical blade is positioned in the discharging section. The feeding hopper of the extruding machine, provided by the invention, has the advantages that the feed is easy, and the power consumption is low.

Description

technical field [0001] The invention relates to the technical field of extruder equipment, in particular to a feeding hopper of an extruder. Background technique [0002] The host of the plastic extruder is the extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. At present, the automatic metering system is used for feeding the plastic extruder. The plastic and powder are stored in the large feeding hopper, and the stored material is fed to the extrusion equipment through the automatic metering system. In principle, as long as there is material in the feeding hopper, production can be done. Continuous, so keeping the feed hopper filled is critical. The existing feeding hopper has a large volume, and a large amount of materials can be poured in at one time, and enter into the feeding port of the plastic extruder from top to bottom by utilizing the gravity without power. However, due to the accumulation of a large amount of...

Problems solved by technology

However, due to the accumulation of a large amount of material in the feeding hopper, this feeding method will easily cause the material at the outlet of the feeding hopper to be blocked, forming a "bridging" phenomenon, which will affect the normal feeding of the feeding hopper, thus causing the plastic extruder to break. The material is idling, and the production cannot continue. At the same time, it has a great impact on the service life of the screw and barrel of the plastic extruder. The manufacturer must equip a special person to stir in the hopper, and the feeding effect fluctuates greatly.

However, the existing forced-feeding adopts the spiral downward pressure type, and the screw downward pressure structure is used in the feeding hopper, which not only often gets stuck due to the uneven size of the material, but also consumes a lot of energy during the long-distance screw pressing process. It is easier to cause the temperature in the feeding hopper to rise and make the material sticky and difficult to feed
