Rubber extrusion device with intermittent push-out function

Abstract

The invention discloses a rubber extrusion device with an intermittent push-out function. The rubber extrusion device comprises an extrusion cavity, a driving shaft, a driven shaft, a motor, a main threaded shaft, an auxiliary threaded shaft, a thermocouple, a heating resistance wire, a rotating shaft, a rotating disk, a piston push rod and a rotary connecting rod; the extrusion cavity is providedwith a feed hopper, the driving shaft, the driven shaft, the main threaded shaft, the auxiliary threaded shaft, the motor, the thermocouple, the heating resistance wire, a heat conduction protectingshell, a guide plate, a thermometer, a material accumulation cavity and a block cover; the left wall of the extrusion cavity is connected to a push-out cavity which is provided with the rotating shaft, the rotating disk, the piston push rod, a material push plate and the rotary connecting rod; and a transmission belt is connected and arranged between the driving shaft and the rotating shaft. According to the rubber extrusion device disclosed by the invention, materials are extruded out through the main threaded shaft, the auxiliary threaded shaft, and temperature is kept through the thermocouple and the heating resistance wire; and the materials are pushed out through the cooperative application of the rotating shaft, the rotating disk, the piston push rod, the material push plate and therotary connecting rod in the push-out cavity finally.

Description

technical field [0001] The invention relates to a mechanical pushing device, in particular to a rubber extruding device which pushes out intermittently. Background technique [0002] With the continuous development of industry, more and more rubber products are used in daily life. In the production process of rubber products, rubber extruder is a basic equipment in the rubber industry and one of the key equipment that affects product quality. It plays a very important role in the production process of tires and rubber products. The development of foreign rubber extruders has experienced plunger extruders, screw-type hot-feed extruders, ordinary cold-feed extruders, primary and secondary thread cold-feed extruders, cold-feed exhaust extrusion Machine, pin cold feed extruder, compound extruder and other stages.

AI Technical Summary

Problems solved by technology

[0003] When extruding rubber materials, often the materials cannot be transported into the equipment of the next process in time when the materials are accumulated in the inner cavity, and it is dangerous to take out the rubber materials by hand, which is time-consuming and laborious; in the prior art, the rubber materials During the processing process, it is easy to cause blockage when the material cools and sticks to the side wall of the device when the transmission is slow; in the prior art, there is a lack of a stable and simple structure pushing device to push the material, and the use of inductive hydraulic pressure is expensive. At the same time, there is a large waste of energy
