At the same time, the driving part 9 will also drive the dust reduction part 8 to perform corresponding dust reduction treatment on the cloth, so that the cloth to be shredded is moistened to avoid the flying of cloth debris after shredding. The rotation of the mounting shaft 3 will drive the dispersion part 4 to operate, so that the cloth on the conveyor is dispersed during transportation, avoiding excessive cloth from entering at one time, so that the cloth is accumulated during shredding, and excessive cloth is avoided from entering, causing the cloth to fly.

[0020] For further information, see Figure 4 , Figure 7 and Figure 8 The dispersing part 4 includes an eccentric wheel 10 fixed on the mounting shaft 3, a dispersing plate 11 which fits with the eccentric wheel 10 is rotatably mounted on the feed bin 2, a transverse plate 12 is fixed on the feed bin 2, and a spring sheet 13 which abuts against the dispersing plate 11 is fixed on the transverse plate 12; In this solution, the driving unit 9 provides power to rotate the mounting shaft 3, thereby driving the eccentric wheel 10 to rotate, cyclically squeezing the dispersion plate 11, and then cooperating with the squeezing and resetting of the spring sheet 13, so that the dispersion plate 11 is continuously shaken, and the cloth transported on the conveyor is shaken to avoid excessive accumulation of cloth entering the cloth shredder 1 at one time.

[0021] For further information, see Figure 4 and Figure 5 The blowing component 5 includes an air cylinder 14 fixed on the feed bin 2, a limit plate 15 is fixed in the air cylinder 14, the driving rod 6 is rotatably connected to the air cylinder 14, the axial direction of the driving rod 6 and the air cylinder 14 are consistent, and a reciprocating thread groove is engraved on the outer wall of the driving rod 6 in the air cylinder 14. A piston plate 16 that fits the limit plate 15 is threadedly sleeved on the driving rod 6. An air outlet pipe 17 is fixed to the bottom of both ends of the air cylinder 14, and an air inlet pipe 18 is fixed to the top. A one-way valve for exhausting air to the outside is installed in the air outlet pipe 17, and a one-way valve for intake air into the air cylinder 14 is installed in the air inlet pipe 18.

[0022] The blowing principle of the blowing component 5 is as follows: first, power is provided by the driving component 9 to make the driving rod 6 rotate accordingly, so that the piston plate 16 connected to the end of the reciprocating thread groove moves back and forth in the air cylinder 14. During each movement, the gas at both ends of the air cylinder 14 is squeezed, so that the air outlet pipe 17 exhausts outwards to avoid the flying of particles after the cloth is torn.

[0023] It should be noted that two air outlet pipes 17 are provided, which circulate and discharge air in turn, and the air flow in the air outlet pipe 17 is small, which can meet the requirement of pressing down the flying cloth without causing the cloth to scatter.

[0024] For further information, see Figure 3-Figure 9 The dust reduction component 8 includes a docking ring frame 19 rotatably mounted on the two side walls of the feed bin 2, a dust reduction cylinder 20 is mounted in the two docking ring frames 19, and a plurality of triggering parts 21 are mounted on the dust reduction cylinder 20. Both ends of the dust reduction cylinder 20 are fixedly connected with a plug-in pipe 22 that is rotatably plugged with the docking ring frame 19 and the inner wall of the feed bin 2, and a docking seat 23 that is slidably plugged with the plug-in pipe 22 is fixed on the outer wall of the feed bin 2, and the outer end of one of the plug-in pipes 22 is docked with the liquid supply device through a hose; In this solution, an external liquid supply design is used to supply liquid to the dust suppression cylinder 20, and the trigger part 21 is used to spray the liquid to wet the outside of the cloth, so that it is less likely to produce broken particles when it is subsequently crushed and shredded.

[0025] For further information, see Figure 4-Figure 7 The driving part 9 includes a driving gear 38 fixed on the mounting shaft 3, the driving rod 6 and the docking ring frame 19. Two driving gears 38 are arranged on the docking ring frame 19. A toothed belt 1 39 is meshed between the mounting shaft 3 and the driving gear 38 on the docking ring frame 19. A toothed belt 2 40 is meshed between the driving rod 6 and the outer side of the driving gear 38 on the docking ring frame 19. The driving motor 7 provides power to rotate the driving rod 6, and the toothed belt 2 40 and the driving gear 38 make the docking ring frame 19 rotate synchronously. At the same time, the toothed belt 1 39 and the driving gear 38 also make the installation shaft 3 rotate synchronously to provide power.

[0026] In this solution, in order to prevent the cloth on the conveyor from being blocked and unable to pass through the dispersion plate 11, the dispersion plate 11 is designed to be made of an elastic material.

[0027] Example 2: Please refer to Figure 5 - Fig. 9 This embodiment further explains the first embodiment, and the difference lies in the development of one specific implementation of the trigger unit 21.

[0028] Specifically, an arc groove 26 is provided on the dust suppression cylinder 20, and the trigger part 21 is installed in the arc groove 26. The trigger part 21 includes an arc plate 27 slidably inserted in the arc groove 26, and a bulk plate 28 is fixed to the bottom of the arc plate 27. A reset member 29 that fits the bulk plate 28 is fixed in the dust suppression cylinder 20, and a drainage unit 30 is provided between the dust suppression cylinder 20 and the bulk plate 28. The drainage unit 30 includes a groove 31 formed on the dust suppression cylinder 20, a sealing ball 32 fitted with the arc plate 27 is installed in the groove 31, a docking groove 33 is formed on the arc plate 27, a drainage channel 35 connected to the docking groove 33 is formed on the arc plate 27 and the bulk plate 28, and a liquid outlet channel 34 connected to the groove 31 is formed in the dust suppression cylinder 20; It should be noted that in order to prevent the sealing ball 32 from entering the docking groove 33 and blocking the drainage channel 35, a magnetic block that is magnetically attracted to the sealing ball 32 is added to the inner wall of the docking groove 33 away from the drainage channel 35, which can prevent the sealing ball 32 from blocking the drainage channel 35.

[0029] Meanwhile, the reset member 29 comprises a baffle plate 36 fixed on the dust suppression cylinder 20 , and a spring sheet 37 abutting against the bulk material plate 28 is fixed on the baffle plate 36 .

[0030] In this solution, when the bulk plate 28 contacts the higher stacked materials, the materials move with the conveyor and will lift up the bulk plate 28, causing the arc plate 27 to move in the arc groove 26 and align the docking groove 33 with the groove 31. Under the action of the water pressure in the dust suppression cylinder 20, the sealing ball 32 will move outward from the groove 31, causing the liquid in the liquid outlet 34 to flow out and enter the drainage channel 35, and then be discharged through the drainage channel 35, thereby achieving targeted drainage and wetting some of the higher stacked fabrics. After the fabrics move away, the bulk plate 28 is pushed by the spring sheet 37 to reset the arc plate 27, and then the sealing ball 32 is pushed into the groove 31 to seal the liquid outlet 34.

[0031] In some preferred embodiments, Figure 6 A compression spring 24 that abuts against the inner wall of the dust suppression cylinder 20 is fixed in one of the docking ring frames 19, and a hemispherical protrusion 25 is fixed on the inner wall of the other docking ring frame 19 and the outer wall of the dust suppression cylinder 20; In this embodiment, as the docking ring frame 19 rotates, the hemispherical protrusion 25 on its inner wall will be driven to contact the hemispherical protrusion 25 on the outer wall of the dust suppression cylinder 20, so that the dust suppression cylinder 20 moves between the two docking ring frames 19, and under the action of the extrusion spring 24, the dust suppression cylinder 20 drives the bulk plate 28 to move accordingly, which can disperse the cloth on the conveyor and avoid cloth accumulation.
