Problems solved by technology

[0006] Aiming at the problem that the discharge size of the existing shredder cannot meet the requirement of a discharge size of 5-8mm, the present invention provides a new type of cutter roller for a single- and double-shaft shredder. The discharge size of the shredder is uniform, The production is stable, the fluctuation is small, and the productivity of the shredder is improved at the same time. The production capacity can reach 900kg / h, which is at least 3 times higher than that of the single-shaft shredder.

Embodiment 1

[0046] like Figure 1 to Figure 4 As shown, the knife roller of a new type of single and double shaft shredder in this embodiment includes a rotating shaft 11 and a roller body 12. A shaft hole is provided in the middle of the roller body 12, the rotating shaft 11 is penetrated through the shaft hole, and the roller body 12 The roller surfaces are provided with wave grooves 121 and a number of movable knife seats 13. The movable knife seats 13 are distributed in the axial direction according to the "herringbone" shape. The movable knife seat 13 is connected with a movable knife 14; the movable knife seat 13 is welded to the wave. Bottom of groove 121.

[0047] In the prior art, the surface of the roller body 12 of the knife roller is smooth. For flexible items such as plastic films, ton bags and discarded fishing nets, due to the material of these substances, the friction with the surface of the roller body 12 is small. In addition, the gap between the movable knife 14 and th...

Embodiment 2

[0050] The structure of this embodiment is basically the same as that of Embodiment 1, and the difference is that, such as Figure 4 As shown, the shape structure of the movable knife 14 is square, including a knife body 141 and four arc-shaped blades 142 placed on one side of the knife body 141. A screw hole is opened along the center of the knife body 141. beyond the end face of the screw hole.

Embodiment 3

[0052] The structure of this embodiment is basically the same as that of Embodiment 2. The difference is that because the movable knife seat 13 is in a high-speed rotation state and is in contact with plastic films, ton bags and discarded fishing nets for a long time, the movable knife seat 13 is worn out. Therefore, the movable knife seat 13 is made of stainless steel, and the movable knife seat 13 is provided with a mounting hole 131 for installing the movable knife 14 . Taken together, there are basically no gaps, preventing fine particles from entering the mounting surface 132 and affecting the normal use of the movable knife 14 .

Abstract

The invention discloses a cutter roller of a novel single-double-shaft shredding machine, and a manufacturing method thereof, and belongs to the technical field of shredding machines. The cutter roller comprises a rotary shaft and a roller body, wherein a shaft hole is formed in the middle of the roller body; the rotary shaft penetrates through the shaft hole; wave grooves and a plurality of moving cutter seats are arranged on the roller surfaces of the roller body; the moving cutter seats are distributed along the axial direction according to the herringbone shape; moving cutters are connected onto the moving cutter seats. The surface of the cutter roller is in a wave shape, the clearance between each moving cutter and a fixed cutter is controlled within the range of 0.4 to 0.5mm, each moving cutter is sharp in cutting edge during the use process, the occurrence of the undesirable phenomenon of winding is avoided, the shredding machine is uniform in discharging size, stable to produce and small in fluctuation, meanwhile, the productivity of the shredding machine is improved, and the capacity can reach to 900kg / h and is improved by at least 3 times compared with a single-shaft shredding machine.

Description

technical field [0001] The invention belongs to the technical field of shredders, and more particularly relates to a knife roller of a novel single- and double-shaft shredder and a manufacturing method thereof. Background technique [0002] A shredder is a machine used for shredding, generally used to process unprocessed raw materials or scraps to make them smaller in size. A typical 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. The shredder is used in the plastic recycling industry, and is often used for the shredding of waste large-diameter PE plastic pipes, bundled plastic films, large piles of plastic sheets and machine head materials. [0003] At present, general customers use shredders for shredding. For example, Chinese patent application number: 201720657433.3, application date: June 7, 2017, the name of the invention is: a knife roller for a double-shaft shredder...
