Power transmission mechanism of double-screw extrusion equipment

Abstract

The invention relates to an improved structure of double-screw extrusion equipment. The double-screw extrusion equipment is a particle-cutting power transmission mechanism in the high-heat condition. A motor (9) is installed on a fixed motor seat stand (10) and can rotate up and down or / and from side to side. Two cylindrical connectors (2) are respectively arranged in two cylindrical connecting housings (1) of a rotary fabricated coupler and are fixed through embedding of a plurality of rubber pins (3), and the two cylindrical connectors (2) are mutually inserted and connected. The cylindrical connecting housings (1), one end of each connecting housing is connected with a rotating shaft of a cutter (7) or an output shaft of the motor (9), and the inner wall of the other end of each connecting housing is uniformly provided with a plurality of semicircular outer holes (1c) in the circumferential direction. The the circumferential-direction outer wall of one end of each connector is provided with a circle of semicircular inner holes (2c), and the other end of each connector extends a convex plate (2b) or a corresponding groove (2a) to the opposite side. The rubber pins (3) are cylinders and are embedded into circular holes on the connecting housings (1) and the cylindrical connectors (2). According to the invention, the assembly space and distance are not reserved in the axial direction in order to connect the cutter with the motor of a double-screw extruder, so that the site is reduced, and the safety is improved.

Description

[0001] technical field [0002] The invention relates to an improved structure of twin-screw extruding equipment, in particular to an improved structure of a power transmission mechanism of twin-screw extruding equipment for processing aquatic products. [0003] Background technique [0004] Twin-screw extrusion equipment, especially expanded extrusion processing technology has been widely used in livestock, poultry, and fish breeding industry, and now it has become a symbol of high-level aquaculture and high-quality feed. There is a growing trend. With the continuous improvement of feed production technology and equipment, extrusion technology has been widely used in aquatic feed production due to its advantages. Extrusion puffing is completed by combining the effects of water, pressure, temperature and mechanical shear. During the extrusion puffing process, the temperature in the extrusion cavity can reach 90-200~C, and the extrusion duration is 10-30 s Therefore, the e...

Problems solved by technology

[0006] Twin-screw extrusion equipment The motor at the other end of the twin-screw extruder is connected to the cutter part through a coupling. The coupling used in the prior art is generally a universal joint coupling structure, which requires axial A certain distance and space require two shafts, the front and rear drive shaft and the driven shaft, together with the devices, appliances, and components on the shaft, such as motors, engines, bearing seats, and working machinery, can move axially during assembly or maintenance. First, move the two shafts axially to both sides, assemble them with their respective shaft ends, and then move toward each other, close them, insert each other for connection, and transmit power. For this reason, motors and other engines have to be installed on the The lower part of the motor seat with wheels can be moved during assembly and disassembly. Of course, a large space and distance need to be reserved. Although it is not necessary to leave a space distance between the front and rear working machines and components during normal work, it is only for the shaft. The connection of the terminal will cause an additional burden on the product or the site, and increase the volume and weight in vain. It is inconsistent with the current pursuit of miniaturization, miniaturization, space saving, and space saving. It is contradictory
