Problems solved by technology

[0006] In view of the fact that the existing shredders are extremely prone to entanglement when processing flexible items, it is troublesome to stop and clean up, workers need to enter the box to clean up, and there are potential safety hazards; at the same time, the size of the output is uneven and does not meet the production requirements. The invention provides a new type of single- and double-shaft shredder, which solves the phenomenon of poor winding of the shredder, improves the unit work efficiency of the shredder, and at the same time, the discharge size of the shredder is uniform, eliminating potential safety hazards

Embodiment 1

[0043] Such as Figure 1 to Figure 7 As shown, a new type of single-axis shredder in this embodiment includes a body 1 and a drop hopper 2 arranged above the body 1. The bottom of the drop hopper 2 is connected to the crushing chamber 3 of the body 1. A shredding assembly is installed, and the shredding assembly includes a first knife roller 4 and a first moving knife 5 installed on the first knife roller 4, a second knife roller 6 and a second moving knife installed on the second knife roller 6. Knife 7, and the first fixed knife 8 and the second fixed knife 9 installed in the body 1, the roll surface of the first knife roller 4 and the second knife roller 6 are all provided with wave grooves, the first moving knife 5 and the second The gap between the second moving knife 7 and the first fixed knife 8 and the second fixed knife 9 is controlled at 0.4-0.5mm; when the first knife roller 4 and the second knife roller 6 rotate, the first fixed knife 8 and the second fixed knife 9...

Embodiment 2

[0049] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 7 As shown, the structural shapes of the first movable knife 5 and the second movable knife 7 are the same, and the shape and structure of the first movable knife 5 / second movable knife 7 are square, including a cutter body 51 and four sides placed on one side of the cutter body 51. An arc-shaped blade 52 is provided with a screw hole along the center of the cutter body 51, and the cutting edge of the arc-shaped blade 52 exceeds the end face of the screw hole.

Embodiment 3

[0051] The structure of this embodiment is basically the same as that of Embodiment 2, except that the movable knife seat 43 is worn out due to the high-speed rotation of the movable knife seat 43 and the long-term contact with plastic films, ton bags, scrapped fishing nets, etc. Larger, so the material of the movable knife seat 43 is stainless steel, and the movable knife seat 43 is provided with mounting holes for installing the first movable knife 5 / second movable knife 7, and the movable knife seat 43 has a mounting surface 431, the mounting surface 431 and the first movable knife 5 / second movable knife 7 are closely fitted together, basically without gaps, preventing fine particles from entering the mounting surface 431 and affecting the normal use of the first movable knife 5 or the second movable knife 7 .

Abstract

A novel uniaxial and biaxial shredder and an operation method thereof are disclosed, belonging to the technical field of shredders. The shredder includes a machine body and a blanking hopper disposedabove the machine body. The lower part of the blanking hopper is connected to a crushing chamber communicating with the machine body. A shredding assembly is mounted in the crushing chamber and includes a first knife roller, first movable knives mounted on the first knife roller, a second knife roller, second movable knives mounted on the second knife roller, first fixed knives mounted in the machine body, and second fixed knives mounted in the machine body. Roller surfaces of the first and second knife rollers are provided with wave-shaped slots. The gap between the first and second movable knives and the first and second fixed knives is controlled to be 0.4-0.5 mm. The surfaces of the first and second knife rollers are wave-shaped, the gap between the fixed knives and the movable knivesis controlled to be 0.4-0.5 mm, the first and second movable knives have sharp blades in a using process, and adverse phenomena such as winding can be avoided.

Description

technical field [0001] The invention belongs to the technical field of shredders, and more specifically relates to a novel single- and double-shaft shredder and its working method. Background technique [0002] A shredder is a machine used for fine crushing, which is generally used to process unprocessed raw materials or scraps to make them smaller in size. A representative example is to shred plastic or rubber scraps and use them as raw materials to melt and granulate them to remake plastic bottles, tires or trash cans, etc. The shredder is used in the plastic recycling industry, and is often used for the crushing of waste large-diameter PE plastic pipes, bundled plastic films, large stacks of plastic sheets and machine head materials. At present, general customers use single-shaft shredders for shredding, but for flexible items such as plastic films, ton bags, and scrap fishing nets, this kind of equipment tends to cause some items to be unable to be torn and wound on the...
