  However, the crusher described in Patent Document 1 has a problem that the object to be crushed is easily clogged in the gap between the peripheral surface of the cylindrical roller and the opening of the support. In addition, the object to be crushed cannot be completely crushed, and the object to be crushed is clogged between the cutting edge of each crushing roller and the peripheral surface of each cylindrical roller. When the object to be crushed is clogged, it is necessary to stop the operation and remove the object to be crushed.

  The present invention has been made paying attention to such a conventional problem, and an object of the present invention is to provide a crusher that is less likely to clog the object to be crushed and can improve work efficiency.

  In order to achieve the above object, a crusher according to the present invention includes a support, a first rotating member, a second rotating member, and a plurality of spacers, the support having an opening, and the first rotation. The member and the second rotating member each have a rotating shaft, a plurality of crushing rollers, and a plurality of cylindrical rollers, each rotating shaft is passed over the opening and arranged in parallel to each other, and both ends can be rotated by the support. Each crushing roller and each cylindrical roller are supported by being alternately arranged in the axial direction on each rotating shaft, and each crushing roller of the first rotating member and each crushing roller of the second rotating member are The crushing rollers of the first rotating member are arranged in close proximity to the sides facing each other and are alternately combined so that a part of the peripheral edge overlaps in the axial direction. In front and Each crushing roller of the second rotating member is opposed to each cylindrical roller of the first rotating member on the circumferential surface, each crushing roller of the first rotating member has a blade around it, and the cutting edge is each crushing roller The crushing rollers of the second rotating member have blades around them, and the cutting edges of the crushing rollers are arranged on the periphery of the crushing rollers of the second rotating member with a predetermined first time difference. The blades of the blades are arranged so as to face the cylindrical roller of the first rotating member at a predetermined second time difference different from the first time difference in order, and the blade tips of the blades are inclined at a predetermined angle with respect to the axial direction of the rotating shaft. Each spacer is provided on the support so as to close a gap between the peripheral surface of each cylindrical roller and the opening.

  The crusher which concerns on this invention can crush a to-be-crushed object by entraining a to-be-crushed object between the 1st rotation member and the 2nd rotation member which are rotationally driven. At this time, each crushing roller of the first rotating member and each crushing roller of the second rotating member are arranged in close proximity to the opposite sides of the opening of the support, and each spacer has a circumferential surface and an opening of each cylindrical roller. Therefore, the object to be crushed is not easily clogged in the gap between each crushing roller and each cylindrical roller and the opening. Furthermore, since the cutting edge of each blade of each crushing roller of the first rotating member and the second rotating member is inclined at a predetermined angle with respect to the axial direction of the rotating shaft, the object to be crushed can be cut along the inclination. It is easy and the crushing object is more difficult to clog. For this reason, it is not necessary to stop the operation and remove the clogged object, and the work efficiency can be improved.

  In the crusher according to the present invention, the cutting edge of each crushing roller of the first rotating member is arranged to face the cylindrical roller of the second rotating member at a predetermined first time difference in the arrangement order of each crushing roller. It is easy to cut the object to be crushed in order. Moreover, since the cutting edge of each crushing roller of the second rotating member is arranged to face the cylindrical roller of the first rotating member with a predetermined second time difference in the arrangement order of each crushing roller, the crushing object is cut in the arrangement order. Is easy. Since the second time difference is different from the first time difference, a time difference occurs when the cutting edge of each crushing roller of the first rotating member and the cutting edge of each crushing roller of the second rotating member mesh. As a result, the object to be crushed is further easily cut, the object to be crushed is not easily clogged, and the work efficiency can be improved.

  According to the present invention, it is possible to provide a crusher that is less likely to clog the object to be crushed and can improve the work efficiency.

Part 54b.

Next, the operation will be described.
The crushing device 50 is mainly used to crush resin products such as automobile bumpers. The crushing device 50 operates the operation unit 54 to rotate the rotary shafts 26 and 27 of the crusher 10 by the driving unit 52, and inputs the material to be crushed from the inlet 53 a of the hopper 53 to crush the material to be crushed. Do. The crusher 10 can crush the material to be crushed by entraining the material to be crushed between the first rotating member 12 and the second rotating member 13 that are rotationally driven.

  At this time, each crushing roller 28 of the first rotating member 12 and each crushing roller 29 of the second rotating member 13 are arranged close to the inside of the side walls 21 facing each other of the opening 24 of the support 11, Since the spacer 14 is provided on the support 11 so as to close the gap between the circumferential surface of each cylindrical roller 30 and 31 and the opening 24, the crushing rollers 28 and 29, the cylindrical rollers 30 and 31, the opening 24, It is difficult for crushing objects to get stuck in the gap. Further, the blade edges 32a, 33a of the blades 32, 33 of the crushing rollers 28, 29 of the first rotating member 12 and the second rotating member 13 are inclined at a predetermined angle with respect to the axial direction of the rotating shafts 26, 27. Therefore, the object to be crushed can be easily cut along the inclination, and the object to be crushed is more difficult to clog. For this reason, it is not necessary to stop the operation and remove the clogged object, and the work efficiency can be improved.

  In the crusher 10, the cutting edges 32 a of the crushing rollers 28 of the first rotating member 12 are arranged to face the cylindrical rollers 31 of the second rotating member 13 at a predetermined first time difference in the arrangement order of the crushing rollers 28. The material to be crushed is easily cut in the order of arrangement. Further, since the cutting edge 33a of each crushing roller 29 of the second rotating member 13 is arranged to face the cylindrical roller 30 of the first rotating member 12 with a predetermined second time difference in the arrangement order of each crushing roller 29, the arrangement thereof It is easy to cut the object to be crushed in order. Since the second time difference is different from the first time difference, a time difference occurs when the cutting edges 32a of the crushing rollers 28 of the first rotating member 12 and the cutting edges 33a of the crushing rollers 29 of the second rotating member 13 are engaged. As a result, the object to be crushed is further easily cut, the object to be crushed is not easily clogged, and the work efficiency can be improved.
