Embodiment 1

[0026] like figure 1 , image 3 and Figure 4 As shown, a rubber pulverizer includes a housing 1, a cutting device, a screening device, and a cooling device. The upper part of the housing 1 is a feed opening 11 , the lower side of the housing 1 is provided with a discharge opening 12 , and the bottom of the housing 1 is a discharge opening 13 . The cutting device is inside the housing 1, including two rollers and a crushing wheel 22. Multiple sets of cutter heads are installed on the rollers, and the cutter heads on the two rollers are interlaced to form a shearing mechanism; the crushing wheel 22 is installed horizontally Below the roller 21, a guide block 26 is also installed on the outer casing 1 of the crushing wheel 22. The crushing wheel 22 includes a crushing knife 23, a first sleeve 24 and a second sleeve 25, and the first sleeve 24 circumferentially A spring is installed, and one end of the spring is connected to the outer circular side wall of the first sleeve 24,...

Embodiment 2

[0029] like figure 2 As shown, a rubber pulverizer differs from the first embodiment in that the pulverizing wheel 22 has an inclination angle with the horizontal direction. The pulverizing wheel 22 rotates on the inclined surface, and the pulverizing knife 23 will pass through the position of the lowest point and the highest point during the rotation process. When the pulverizing knife 23 is at the lowest point, since the gravitational force and the centrifugal force on the pulverizing knife 23 are on the same side, The force of the spring is relatively large, and the protruding length of the pulverizing knife 23 is relatively long. When the pulverizing knife 23 is at the highest point, the gravity of the pulverizing knife 23 is not on the same side as the centrifugal force, and the force of the spring is small, so the protruding length of the pulverizing knife 23 is relatively short. , The crushing knife 23 can also expand and contract in the first through hole when not tou...

Abstract

The invention discloses a rubber pulverizer, and belongs to the field of rubber processing. The rubber pulverizer comprises a shell, a cutting device, a screening device and a cooling device, whereinthe cutting device comprises two rollers and a crushing wheel, the crushing wheel is composed of two sleeves and a crushing knife, air channels are formed in the sleeves, and the cooling device comprises a vortex tube. When rubber is crushed by the pulverizer, the crushing knife makes contact with the rubber and is moved by the thrust of the rubber, and air is compressed in the process that the crushing wheel is moved, so that air enters the vortex tube, and cold air is generated to cool the crushing knife. By adopting the scheme to crush the rubber, the service life of the crushing knife canbe prolonged, and the rubber is prevented from melting so as not to adhere to the crushing knife and not to influence the crushing effect.

Description

technical field [0001] The invention relates to the field of rubber processing, in particular to a rubber pulverizer. Background technique [0002] Rubber materials have viscoelasticity, high elasticity and electrical insulation after vulcanization, and have excellent durability and solvent resistance. They are widely used in people's life and production, and they are most used in automobile tires and rubber shoes. With the rapid development of my country's industry, agriculture and transportation, the consumption of rubber is increasing, and there are more and more waste rubber. Since waste rubber will not decompose naturally, a large amount of waste rubber and tires will accumulate and be disposed of improperly, which will not only cause waste of resources, but also seriously pollute the environment and cause "black pollution". Proper treatment and resource recovery of waste tires can protect the environment and achieve sustainable development. [0003] Waste rubber can ...
