Special extrusion machine for producing edible conveying special monofilaments

Abstract

The invention provides a special extrusion machine for producing edible conveying special monofilaments. The extrusion machine comprises a cylinder, a motor, an extrusion device, a feed inlet and a discharge opening. The feed inlet is formed in one end of the cylinder, the discharge opening is formed in the other end of the cylinder, a material cavity is axially arranged in the cylinder, the extrusion device is rotationally arranged in the material cavity, and an output shaft of the motor is connected with the extrusion device through a shell. The extrusion device comprises a screw, the screw is sequentially provided with a feeding mechanism, a melting mechanism, a plastification mechanism and an extrusion mechanism, and the feeding mechanism is close to the shell. The special extrusion machine has the advantages that the distance between an outer die and a core die does not need to be adjusted, that is, the step of adjusting deflected walls of extruded products is omitted, and accordingly the phenomena that raw materials are wasted and labor and time cost is wasted due to deflected wall adjustment can be avoided. The phenomenon that glue overflows due to vacuumizing in the extrusion dehydration and expansion drying procedures is eliminated, product quality is guaranteed, and the percent of pass of the products is increased.

Description

technical field [0001] The invention belongs to the technical field of equipment for a monofilament production line, and in particular relates to an extruder for producing a special monofilament for food-grade transportation. Background technique [0002] The general trend of the development of conveyor belts in the world today is to develop in the direction of multi-variety, high performance, light weight, multi-function, energy saving, safety, environmental protection and long life. The modern conveyor belt industry should diversify and develop in the direction of high performance, light weight, multi-function, safety and environmental protection. Traditionally, canvas or rubber conveyor belts are used. The products are heavy, have high energy consumption and do not meet the requirements of environmental protection and hygiene. PVC and polyethylene materials even contain harmful ingredients to the human body. In the production process of the existing food-grade special mo...

Problems solved by technology

[0003] In the existing technology, the middle extruder has the following disadvantages: the outer mold and the mold core are independent parts, and the mold core cannot be guaranteed to be at the central axis of the outer mold after assembly, which will easily cause the extrusion tube to appear eccentric, which will The phenomenon of partial wall of the extruded product causes unqualified products, which not only wastes raw materials, but also increases manpower and time costs; during the mixing and plasticizing process, the pressure in the wear-resistant layer is relatively high, and the exhaust device is exhausted. When the gas is blown, there will often be a phenomenon of gumming, which not only causes waste of raw materials, but also affects the quality of the product; when the screw of the extruder is a second-stage exhaust screw, if the flow rates of the first metering section and the second metering section are not equal , it will cause the exhaust port to leak or extrusion fluctuations; the connection between the screw and the shell is sealed by a packing, sometimes the packing is prone to leakage, and the packing needs to be recompressed frequently, resulting in unnecessary operation
