Extruding machine capable of automatically discharging screw rod

Abstract

The present invention relates to the technical field of extruding machines and particularly to an extruding machine capable of automatically discharging a screw rod. The extruding machine capable of automatically discharging the screw rod comprises a feeding system, an extruding system and a discharging system in a successive connection, and also comprises a transmission system for driving the extruding system; the transmission system comprises a motor and a gearbox, the extruding system comprises a machine barrel and a screw rod penetrating through the machine barrel, an end part of the screwrod is connected with the gearbox, a screw rod push-out mechanism is arranged between the gearbox and the machine barrel, and the screw rod push-out mechanism is used for pushing the screw rod out ofthe machine barrel. In the extruding machine capable of automatically discharging the screw rod, the screw rod push-out mechanism can push the screw rod out of the machine barrel, is reasonable in design, saves time and effort, also conducts improvement of the whole device, is optimized in structure and well solves problems existing in the prior art.

Description

technical field [0001] The invention relates to the technical field of extruders, in particular to an extruder capable of automatically extruding a screw. Background technique [0002] Screw extruder is widely used in food processing such as cereal food, snack food, nutritional rice flour, tissue protein, rice reconstitution, starch gelatinization, caramel products, pet food, aquatic feed, etc. Cutting force, frictional force, heating and other effects can realize the processing of solid food materials such as crushing, kneading, mixing, aging, sterilization, pre-drying, forming, etc. The screw extruder can produce puffed, textured or other shaped products. [0003] The following problems usually exist in the existing screw extruder: 1. The screw is the most important part in the screw extruder. The screw is usually arranged in the barrel, and the inner wall of the barrel and the screw jointly complete the extrusion of the material. Extrusion After the completion, the screw...

AI Technical Summary

Problems solved by technology

[0003] The following problems usually exist in the existing screw extruder: 1. The screw is the most important part in the screw extruder. The screw is usually arranged in the barrel, and the inner wall of the barrel and the screw jointly complete the extrusion of the material. Extrusion After the completion, the screw needs to be pulled out from the barrel for cleaning. Generally, the screw is pulled out of the barrel by manpower, especially when the viscosity of the material is high, the manual extraction is time-consuming and laborious, and it is difficult to pull out; 2. The screw extruder often Using a disc cutter as its cutting device, the rotation plane of the blade is parallel to the end face of the template. Usually the cutting device will rotate out or back with the random head. When the blade rotates back with the random head, because the distance between the blade and the template end face is relatively close When the blade and the end face of the template interfere with each other, that is, the blade will scratch the end face of the template or the end face of the template will damage the blade; 3. The initial molding material extruded by the screw extruder is generally waste material, and the waste material and the subsequent The normal molding materials are separated. In the prior art, the discharge hopper is generally used for manual separation, but some waste materials will adhere to the discharge hopper, thereby polluting the subsequent molding materials; 4. The materials sometimes contain Magnetic substance, the screw extruder in the prior art is not designed to remove the structure of the magnetic substance
