Ultrasonic cutting device for reclaimed rubber

Abstract

The invention relates to an ultrasonic reclaimed rubber cutting device. The ultrasonic reclaimed rubber cutting device comprises a base, a coiling block, a rotation shaft, a supporting block, an ultrasonic generator, a wiring block, an ultrasonic tool, an air cylinder, a piston and a tool base. A supporting component of the coiling block is manufactured through porous materials. After the porous materials are inflated with high-pressure gas, a static pressure gas film can be generated on the outer wall of a main shaft, the gas film can suspend the coiling block, air suspension is achieved, andaccordingly influences on a bearing due to the rubber belt temperature are avoided. In addition, an ultrasonic cutting device body is adopted, a cutting edge is not needed during ultrasonic cutting,the molecular energy of rubber is activated through vibration energy, accordingly, a molecular chain of the rubber is opened, and cutting is achieved. The rubber is softened and melted through energygenerated through ultrasonic vibration, edge breakage, damage and other defects cannot be generated on the cut edge of the rubber material, and cutting banding is tidy.

Description

Technical field: [0001] The invention belongs to the technical field of reclaimed rubber production equipment, and in particular relates to an ultrasonic cutting device for reclaimed rubber. Background technique: [0002] Reclaimed rubber is processed from the vulcanized scraps in the production of rubber products. It has a certain degree of plasticity and can be reused. Reclaimed rubber for short. According to the different waste rubber used, reclaimed rubber is divided into outer tires, inner tubes, rubber shoes and so on. [0003] At present, the refining process of reclaimed rubber in my country is to repeatedly knead the desulfurized rubber powder through a reclaimed rubber kneader, and then refine the kneaded rubber into thin sheets by the refiner, and then wrap the film manually. On the reel, when it reaches a certain weight, it is cut into pieces with scissors, and finally the film is weighed. In order to meet the specified weight requirements, it is often necessary...

Problems solved by technology

However, the temperature of the reclaimed rubber tape after refining is high. Even if two-stage cooling rollers are set in this patent, the tape wound on the tape reel still has a relatively high temperature, and the temperature is transferred to the bearing of the reel through the tape reel. , which seriously affects the service life of the bearing. In addition, as we all know, the tape is relatively elastic, and the cutter must be pressed tightly when cutting to facilitate cutting. Even so, the cutting surface is not smooth, resulting in defects such as chipping and damage
