Structure for cleaning bottom of drum for rubber processing

Abstract

The invention provides a structure for cleaning the bottom of a drum for rubber processing, and belongs to the field of rubber plasticizing equipment, the structure comprises a driving shaft, a glue scraping trowel, a cylinder, a left supporting plate and a right supporting plate, wherein the left supporting plate and the right supporting plate are arranged in parallel, the driving shaft is vertically arranged between the left supporting plate and the right supporting plate and is rotatably connected with the left supporting plate and the right supporting plate; the glue scraping trowel is fixedly arranged on the driving shaft through two fixing seats; one end of the cylinder, away from an output shaft, is hinged with the left supporting plate through a bracket; the output shaft end of thecylinder is hinged with one end of a driving rod; the other end of the driving rod is fixedly connected with the driving shaft, the output shaft of the cylinder moves up and down and drives the driving shaft to rotate through the driving rod, the glue scraping trowel comprises a positioning frame and a blade, the positioning frame is fixedly connected with the fixing seats, the blade is fixedly arranged at the upper end of the positioning frame, and a chamfer is arranged at one end of the blade, away from the driving shaft. The device can automatically achieve continuous glue scraping, and has simple control and good glue scraping effect.

Description

technical field [0001] The invention belongs to the field of rubber processing equipment, and relates to a training machine, in particular to a cleaning structure for the bottom of a rubber processing cylinder. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under the action of a small external force. General-purpose rubber refers to rubber types that partially or completely replace natural rubber, such as styrene-butadiene rubber, butadiene rubber, isoprene rubber, etc., which are mainly used to manufacture tires and general industrial rubber products. main species of [0003] In the process of rubber processing, a lot of equipment needs to be used to improve the plasticity of rubber.

Problems solved by technology

[0003] In the process of rubber processing, a lot of equipment needs to be used to improve the plasticity of rubber. They are collectively called plasticizing devices. The rotation of the roller is involved in the gap between the two rollers, and it is subjected to strong shearing to achieve the purpose of mastication or mixing. Because the rubber has a certain viscosity, it is easy to stick to the roller, so it is necessary to set up a scraping device. At present, most commonly used scraping devices are semi-automatic, and the efficiency is low.
