Description

A waste tire rubber coarse shredder

technical field

The utility model relates to a machine for coarsely crushing waste tires and rubber products.

Background technique

With the development of automobile, light industry, chemical industry, and transportation industry, the large-scale use of tires and rubber products has been promoted, and a large number of scrap tires and rubber products will inevitably be produced. If they cannot be disposed of in time, it will not only cause waste of resources, but also affect the social environment. bring a lot of pollution. At present, there are many ways to recycle waste tires and rubber at home and abroad, but no matter what method is used, it is inseparable from the production process of crushing, cutting and crushing waste tires and rubber. Most of the existing crushing machines are large-scale equipment , large volume, high power, high price, large one-time investment, which is not conducive to popularization and use in small and medium-sized rubber processing enterprises in my country. Waste tire chips, especially waste steel wire radial tire chips, are directly crushed.

Contents of the invention

The purpose of the utility model is to propose a waste tire rubber coarse shredder, which integrates the functions of crushing and cutting into pieces and coarse crushing, and can directly carry out coarse crushing processing on various types of waste tire rubber sheets.

The technical solution adopted by the utility model is: waste tire rubber coarse crusher, mainly composed of machine base, motor, reducer and crushing mechanism, the main motor is connected with the working rotor of the crushing mechanism through the reducer, and the working rotor is a belt The conical variable-diameter and variable-pitch screw rotor is composed of two parts: the screw feeding blade and the crushing gear. The working rotor cooperates with the crushing chamber to form a spiral pair, and can move axially in the crushing chamber. There is an adjustment device at the rear end of the working rotor The distance device is characterized in that a fixed blade is provided at the feeding port of the crushing chamber, and the fixed blade cooperates with the screw feeding blade of the working rotor to form a cutting mechanism.

Compared with the prior art, the utility model has remarkable characteristics. By setting a fixed blade at the feeding port of the crushing chamber, the cutting mechanism is composed of the fixed blade and the spiral feeding blade, so that the machine has a new technical effect, and it can Large pieces of waste tire rubber that have not been crushed and cut into pieces are cut and coarsely crushed at the same time, which greatly reduces the size limit for raw materials. One machine is compatible with both cutting and crushing functions. In the waste tire rubber recycling process The tire crusher is omitted, which simplifies the process, reduces investment, greatly reduces energy consumption, operating costs and maintenance workload, and reduces the labor intensity of workers, which is conducive to the automatic control of the tire rubber recycling process. Because this machine adopts the working method of cutting first and then crushing, the working capacity of the machine is greatly enhanced, so it is suitable for direct crushing of various waste tire rubber, especially waste steel wire radial tire chips.

Detailed ways

As shown in Figure 1 and Figure 2, the waste tire rubber coarse shredder is mainly composed of a machine base, a motor, a reducer and a crushing mechanism. 5, the output shaft of the reducer 5 is connected to the working rotor 10 of the crushing mechanism through the coupling 6, and drives the working rotor 10 to run. The spiral feeding blade and the crushing gear are composed of two parts, and the working rotor 10 cooperates with the inner wall of the crushing chamber 15 to form a spiral pair. The feeding port of the pulverizing chamber 15 is provided with a fixed blade 9, the edge of which is arc-shaped, cooperates with the screw feeding blade of the working rotor 10 to form a cutting mechanism, and cuts the waste tire rubber sheet.

The discharge end of the crushing chamber 15 is provided with a cavity with a discharge port, and a cooling water tank is provided along the periphery of the crushing chamber 15, and the circulating cooling water is input from the water collecting tank 14 through the cooling water pipe 13.

At the rear end of the working rotor 10, there is a distance adjusting device 12. The distance adjusting device 12 is a worm gear distance adjusting device. The thrust bearing drives the working rotor 10 to move axially in the crushing chamber 15. When the machine is turned on, the clearance of the conical working surface of the working rotor 10 can be adjusted arbitrarily according to the process requirements, so as to achieve the purpose of adjusting and controlling the discharge particle size.

The feeding of this machine adopts a feeding system composed of feeding gear rollers, conveyor belts and feeding motors. The conveyor belt extends to the top of the feeding hopper 8 of the machine, and adopts electronically controlled stepless speed change, so as to achieve stable load of the main machine. purpose. The discharge system of this machine includes a discharge conveyor belt 16, a conveyor belt reducer 17 and a discharge motor 18. The pulverized material falls on the discharge conveyor belt 16 through the discharge port and is sent out.

In the running state, the blocky waste tire rubber sheet enters the crushing chamber 15 evenly through the feeding hopper 8, and is first cut into small pieces by the cutting mechanism composed of the fixed blade 9 and the screw feeding blade, and then sent into the crushing chamber 15 by the screw feeding blade. The crushing gear constitutes the compression crushing section, and the coarsely crushed colloidal particles are discharged from the discharge port.
