The hexagonal driving shaft 34 on the inner side of the knife box 23, the non-transmission side knife box wall panel 7 and the transmission side knife box wall panel 23 are also connected to the hexagonal passive main shaft 12, the hexagonal passive main shaft 12 is fixed with the hexagonal passive shaft gear 21, the hexagonal driving shaft 34 is fixed with the hexagonal driving shaft gear 35 meshing with the hexagonal passive shaft gear 21, the hexagonal driving shaft 34 and the hexagonal passive main shaft 12 are both provided with a plurality of groups of moving blades 33 and moving blade spacer rings 11, and the opposite surfaces of the two knife box side wall panels 8 are both fixed with a plurality of groups of long combing knives 13 and short combing knives 14. The speed reducer motor 30 provides the rotation force, and drives the hexagonal driving shaft 34 to rotate after the speed is reduced by the cycloid speed reducer 29, and the hexagonal passive shaft gear 21 can rotate under the meshing transmission action of the hexagonal driving shaft gear 35 and the hexagonal passive shaft gear 21, and the medical waste is crushed by the long combing knives 13 and the short combing knives 14 as well as the moving blades 33 and the moving blade spacer rings 11.

[0024] The hexagonal driven shaft gear 21 and the hexagonal driving shaft gear 35 are respectively fastened to the hexagonal driven main shaft 12 and the hexagonal driving shaft 34 by means of gear axial positioning fastening nails 22. Two sets of gear oil tanks 20 corresponding to the hexagonal driven shaft gear 21 and the hexagonal driving shaft gear 35 are fixed on the inner side of the transmission side tool box wall panel 23. A sealing box 18 is fastened on the gear oil tank 20 by bolts. A high-strength waterproof seal 19 for the gear oil tank is provided on the inner side of the sealing box 18. The hexagonal driven shaft gear 21 and the hexagonal driving shaft gear 35 are respectively located in the two sets of gear oil tanks 20, and the hexagonal driven shaft gear 21 and the hexagonal driving shaft gear 35 can be lubricated by oil.

[0025] The two ends of the opposite surfaces of the two knife box side wall panels 8 are respectively fixed with a comb knife upper fixed clamp 31 and a comb knife lower fixed clamp 32. The long comb knife 13 and the short comb knife 14 are respectively fixed to the knife box side wall panel 8 by the comb knife upper fixed clamp 31 and the comb knife lower fixed clamp 32. The long comb knife 13 and the short comb knife 14 as well as the movable blade 33 and the movable blade spacer ring 11 are correspondingly arranged, specifically, the long comb knife 13 and the movable blade spacer ring 11 are correspondingly arranged, and the short comb knife 14 and the movable blade 33 are correspondingly arranged, and the two cooperate with each other to achieve the crushing and processing of medical waste.

[0026] The left ends of the hexagonal active shaft 34 and the hexagonal passive main shaft 12 are rotatably arranged in the non-transmission side tool box wall panel 7 through the non-transmission side double-row self-aligning bearing 4, the inner ring of the non-transmission side double-row self-aligning bearing 4 is fastened and installed on the outer side of the hexagonal active shaft 34 and the hexagonal passive main shaft 12 through the self-aligning bearing disassembly sleeve 2, and the non-transmission side double-row self-aligning bearing 4 is fixed to the outer side of the hexagonal active shaft 34 and the hexagonal passive main shaft 12 through the disassembly sleeve stop lock nut 1, wherein the self-aligning bearing disassembly sleeve 2 is wedge-shaped, and the non-transmission side double-row self-aligning bearing 4 is a tapered bearing. The self-aligning bearing disassembly sleeve 2 can make the inner ring of the non-transmission side double-row self-aligning bearing 4 more closely connected with the hexagonal active shaft 34 and the hexagonal passive main shaft 12, thereby improving the transmission efficiency. The left end surface of the non-transmission side tool box wall panel 7 is fastened with a shaft end protection box 3 by bolts, and the left ends of the hexagonal active shaft 34 and the hexagonal passive main shaft 12 can be protected by the shaft end protection box 3.

[0027] The right ends of the hexagonal driving shaft 34 and the hexagonal passive main shaft 12 are rotatably arranged in the transmission side tool box wall panel 23 through the transmission side double-row self-aligning bearing 24. The right ends of the hexagonal driving shaft 34 and the hexagonal passive main shaft 12 are both threadedly connected with the hexagonal passive shaft axial locking bolt 25. The outer side of the hexagonal passive shaft axial locking bolt 25 is sleeved with a bolt gasket 26. The bolt gasket 26 can press the inner ring of the transmission side double-row self-aligning bearing 24 to the right end of the hexagonal passive shaft gear 21, so that the inner ring of the transmission side double-row self-aligning bearing 24 is more tightly connected with the hexagonal driving shaft 34 and the hexagonal passive main shaft 12. The right end surface of the transmission side tool box wall panel 23 is fastened with an axial locking bolt protection box 27 by bolts, which can protect the hexagonal passive shaft axial locking bolt 25.

[0028] The outer sides of the left ends of the hexagonal driving shaft 34 and the hexagonal passive main shaft 12 are embedded with non-transmission side embedded axial positioning sleeves 9, and the left ends of the opposite surfaces of the two tool box side wall panels 8 are fixed with non-transmission side high-hardness steel tool box partitions 10 sleeved on the outside of the non-transmission side embedded axial positioning sleeves 9. The outer sides of the right ends of the hexagonal driving shaft 34 and the hexagonal passive main shaft 12 are embedded with transmission side embedded axial positioning sleeves 16, and the left ends of the opposite surfaces of the two tool box side wall panels 8 are fixed with transmission side high-hardness steel tool box partitions 15 sleeved on the outside of the transmission side embedded axial positioning sleeves 16. A crushing zone is formed between the non-transmission side high-hardness steel tool box partitions 10 and the transmission side high-hardness steel tool box partitions 15 for crushing medical waste.

[0029] Because in the prior art, when the moving blade 33 and the moving blade spacer 11 are installed on the outside of the hexagonal active shaft 34 and the hexagonal passive spindle 12, although the knocking is very tight during the initial installation, and the non-embedded axial positioning sleeve early structure is installed at both ends to fix the axial position of the moving blade 33, the positioning sleeve is squeezed tightly at both ends in the initial state and can rotate with the shaft, but after the moving blade 33 and the moving blade spacer 11 rotate for a certain period of time, the axial gap increases, and the moving blade 33 and the moving blade spacer 11 produce a slight axial displacement, which loses the axial squeezing of the non-embedded axial positioning sleeve early structure and also loses the rotational power. Due to its own heavy weight, the spindle wears the inner hole of its non-embedded axial positioning sleeve early structure while the spindle also wears, commonly known as "sweeping the hall". In actual operation, this early structure of non-embedded axial positioning sleeve not only increases the wear of the inner hole, but also increases the wear of the contact surface between its end face and the rotating moving blade 33 or the moving blade spacer ring 11 because it cannot rotate with the two main shafts. The axial dimension of the early structure of the non-embedded axial positioning sleeve becomes shorter, and the axial positioning function of the moving blade 33 is lost, which further causes the axial clearance between the moving blade 33 and the moving blade spacer ring 11 on the hexagonal active shaft 34 and the hexagonal passive main shaft 12 to become larger, accelerates the axial displacement of the moving blade 33, and aggravates the extrusion wear of the high-hardness steel knife box partition 10 on the non-transmission side, so that the aperture of the high-hardness steel knife box partition 10 on the non-transmission side becomes larger, causing more crushed materials to leak out of the gap, and the debris liquid flows into the bearing, causing the bearing to be damaged and stopped for maintenance.

[0030] After the embedded axial positioning sleeve is adopted in the present device, no matter how long the movable blade 33 runs, the gap between it and the movable blade spacer ring 11 changes, and it can still effectively rotate with the main shaft. There is no "sweeping hall" wear of the inner hole, and there is no relative friction between the axial direction and the movable blade 33 and the movable blade spacer ring 11, and the embedded axial positioning sleeve will not be worn short.

[0031] In addition, the outer sides of the embedded axial positioning sleeve 16 on the transmission side and the embedded axial positioning sleeve 9 on the non-transmission side are fixed with a seepage slag rotating disk 17. If a small amount of liquid or debris flows out, it can be thrown off by the centrifugal force of the seepage slag rotating disk 17 to prevent it from flowing into the bearing. In order to better prevent the debris and liquid from splashing and soaking into the bearing.

[0032] A multiple labyrinth seal fixing plate 5 is fixed to the inner side of the tool box wall panel 7 on the non-transmission side, and a multiple labyrinth seal rotating plate 6 cooperating with the multiple labyrinth seal fixing plate 5 is fixed to the outer side of the hexagonal driving shaft 34 and the hexagonal passive main shaft 12. The cooperation between the multiple labyrinth seal fixing plate 5 and the multiple labyrinth seal rotating plate 6 can more reliably prevent debris, residual liquid, etc. from infiltrating into the double-row self-aligning bearing 4 on the non-transmission side, greatly extending the service life of the bearing, reducing the economic loss of downtime maintenance due to shaft and bearing damage, and saving machine maintenance costs.
