Problems solved by technology

At the same time, the structure setting of the cutter of the crusher is unreasonable, and the crushing efficiency is low
[0004] In addition, the movable knife and the movable cutter head of the existing whole tire crusher are integrated. Since the movable knife is easily damaged, the entire movable knife needs to be replaced frequently. The replacement process is time-consuming and laborious. Genius can complete the replacement operation. In order to reduce the dismantling of the whole machine, the blunt edge of the blade is still working, which will cause power consumption and burn out the motor. I am afraid that the motor will burn out and match the high-power motor, resulting in high energy consumption and low output. 2 to 3 times, further reducing work efficiency

Embodiment 1

[0055] see Picture 1-1 , Figure 1-2 , Figure 1-3 , figure 2 , image 3 , Image 6 , the present invention discloses a whole tire crushing equipment for recycling waste tires. The crushing equipment includes a frame 1, and two rotating shafts 2 and 3 arranged in parallel are arranged on the frame 1: a first rotating shaft 3, a second rotating shaft 2, two The two rotating shafts 2 and 3 rotate correspondingly; preferably, the cross-sections of the two rotating shafts are quadrilateral, pentagonal or hexagonal. A plurality of moving knife mechanisms and a plurality of fixed knife mechanisms are closely arranged on each rotating shaft 2 and 3 respectively in cross-displacement. The moving knife mechanism on the first rotating shaft 3 corresponds to the fixed knife mechanism on the second rotating shaft 2 , and the moving knife mechanism on the second rotating shaft 2 corresponds to the fixed knife mechanism on the first rotating shaft 3 . The moving knife mechanism and t...

Embodiment 2

[0071] see Figure 4 , 18 The difference between this embodiment and Embodiment 1 is that, in this embodiment, the cross section of the fixed knife 8 is a ring-shaped structure, and the fixed knife 8 and the fixed knife disk 100 are fixed by key pins 15 .

[0072]Specifically, the fixed knife mechanism is composed of a fixed knife ring and a fixed knife disc; the diameter is smaller than that of the moving knife mechanism; the fixed knife is circular, or bisected, trisected or quartered; There are screw countersunk holes at both ends of the divided, trisected or quartered arcs, and the screws pass through the countersinks to connect with the corresponding threaded holes on the fixed knife disc; the fixed knife ring is close to the fixed knife disc. One side is an inner arc surface, which is set close to the outer circle of the fixed knife disc; the side of the fixed knife ring close to the fixed knife disc is provided with a convex / concave keyway, and the corresponding positi...

Embodiment 3

[0074] see Figure 5 The difference between this embodiment and Embodiment 1 is that in this embodiment, the cross section of the fixed knife 80 is a circular structure, and a number of protrusions 801 are distributed outside, and the fixed knife 80 and the fixed knife disk 100 pass through the key pin 15 fixed.

[0075] The outer circle of the disc type can be smooth, and can also be provided with a convex tooth shape, a helical tooth shape, etc., and the two shafts rotate inward synchronously. When the moving knife is tangent to the fixed knife on the two sides and the second rotating shaft corresponds to the fixed knife, the two moving knives on the two sides of the fixed knife are mutually shaped to close the window, and the right-angled edges on the two sides of the moving knife complete the shearing.

[0076] see Figure 19 to Figure 21 , the cross section of the fixed knife 80 is ring-shaped, and the fixed knife is provided with a half-disk or a third or a quarter arc...

Abstract

The invention discloses a crushing device for whole recovered waste and old tyres, and its cutter mechanism. The cutter mechanism comprises a mobile cutter, a stationary cutter, a mobile cutter disc, a stationary cutter disc and a mobile cutter arranged on the mobile cutter disc, and the mobile cutter comprises a plurality of mobile cutter blocks; a stationary cutter mechanism comprises the stationary cutter disc and the stationary cutter arranged on the stationary cutter disc; and each of the mobile cutter blocks comprises a projection, one side surface of the projection is a front cutting edge, and an angle between the front cutting edge and the surface of the projection far from the mobile cutter disc is an acute angle. The crushing device for whole recovered waste and old tyres and its cutter, which enable cutting rakes to be arranged at the front cutting edges of the mobile cutter blocks, allow the tyres to be crushed to be tightly buckled, so the crushing efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of tire crushing, and relates to crushing equipment, in particular to a whole tire crushing equipment for recycling waste tires; at the same time, the invention also relates to a cutter for the whole tire crushing equipment for recycling waste tires. Background technique [0002] Nowadays, in order to make the rubber in old tires can be used again, there are tire shredders, including whole tire shredders for tires. [0003] The existing whole tire crusher needs 2-3 times of reflux for continuous crushing to obtain 60-80mm 3 Large rubber blocks, the whole machine needs to be equipped with a large filter steel mesh. At the same time, the structure setting of the cutter of the crusher is unreasonable, and the crushing efficiency is low. [0004] In addition, the movable knife and the movable cutter head of the existing whole tire crusher are integrated. Since the movable knife is easily damaged, the entire mo...
