Description

Technical Field

[0001] The invention relates to the technical field of particle waste recycling, in particular to a crushing device for particle waste recycling. Background Art

[0002] In order to save resources, some industrial manufacturers will use waste recycling to reduce costs during the production process. In the process of recycling particle waste, a crushing device is needed to crush the raw materials to ensure the thoroughness of particle crushing and facilitate recycling. However, the existing crushing device still has certain use defects during use, such as:

[0003] Patent application publication number CN218700491U discloses a rubber compound recycling and crushing device, wherein a crushing assembly for crushing rubber compound is arranged on the upper part of the frame, a cover plate for dust prevention is arranged on one end of the crushing assembly, and a shielding curtain for dust prevention is arranged on the other end of the crushing assembly. Since the cover plate and the shielding curtain are designed on the upper part of the crushing assembly, the present invention can prevent rubber particle dust from being scattered around when the crushing device is working, thereby solving the problem that a large amount of black dust particles will be generated during the crushing process of rubber in the prior art, and due to the lack of dust treatment protection design, the rubber dust particles will not only cause harm to the operator's body, but also pollute the air environment;

[0004] In the above-mentioned document, in the process of crushing rubber particles, the device needs to open the cover plate first to put the rubber particles into the lower box, and then the shaft drives the blade to rotate to complete the crushing of the rubber particles. The shaft and the blade are rotatably installed inside the lower box, and the blades are evenly distributed on the outside of the shaft, which makes it inconvenient to fix the movement trajectory of the blade, and there will be accumulation of rubber particles at the lower end of the lower box, which may easily lead to incomplete crushing of the rubber particles, affecting the crushing effect of the device;

[0005] Patent application number CN202322898985.1 discloses a composite material crushing and cooling device, including a cavity, the cavity is cylindrical, a main shaft is rotatably installed in the cavity, a plurality of blades are arranged on the outside of the main shaft, the main shaft is a hollow structure with openings at both ends, and plugging connectors are arranged at the openings at both ends of the main shaft. The hollow structure inside the main shaft and the plugging connector form a closed cavity, and the cavity is filled with coolant. The main shaft rotates in the cavity, driving the blade to break the composite material to prevent the temperature of large pieces of material from rising too fast. The blade has a relatively sharp blade, and can effectively break the material under the rotation of the main shaft. At the same time, since the blade and the axis of the main shaft are inclined, the composite material can be transported forward, and the broken material is discharged from the discharge port;

[0006] In the above document, when the device is working, the main shaft will be driven to rotate by the motor, thereby driving the blade on the outside of the main shaft to rotate and crush the composite material, while the tool is fixedly installed on the outside of the main shaft, and the main shaft can only rotate inside the frame, resulting in the fixed movement trajectory of the tool during rotation, which may easily cause the material to accumulate at the bottom of the cavity during the crushing process of the device, and it is difficult for the crushing knife to completely crush it, which may easily result in incomplete crushing, affecting the crushing effect of the device.

[0050] When the crushing device for recycling waste particles is used, the output shaft 9 will drive the flipping member 15 to rotate forward during the forward rotation, thereby flipping the waste particles at the lower end of the crushing box 5;

[0051] After the device crushes the granular waste, it is necessary to discharge the device from the lower end of the discharge port 7. At this time, the driving motor 8 will drive the output shaft 9 to rotate in the opposite direction. During the reverse rotation of the output shaft 9, the ratchet 17 and the ratchet teeth 19 will be in a meshing state, and the torsion spring 20 will expand and push the ratchet teeth 19 to mesh with the ratchet 17.

[0052] Embodiment 3: This embodiment is as follows Figure 1-Figure 3 and Figure 7-Figure 9 As shown, in order to solve the problem that the existing device is difficult to control the feed position to close, the device can automatically control the feed position switch, and the specific contents are as follows:

[0053] An extrusion piece 29 is fixedly installed on the end of the sliding plate 24 away from the moving cylinder 25, a fixing piece 30 is fixedly installed inside the device body 2, and a main air bag 31 is bonded inside the fixing piece 30, and an air pipe 32 is fixedly installed inside the main air bag 31, a limiting piece 33 is fixedly installed on the upper end of the crushing box 5, and a push rod 35 is slidably installed inside the limiting piece 33, and an auxiliary air bag 34 is bonded to the end of the push rod 35 close to the limiting piece 33, and at the same time, the auxiliary air bag 34 is fixedly connected to the end of the air pipe 32 away from the main air bag 31, a mounting plate 36 is fixedly installed on the outer side of the push rod 35, and a sealing plate 2 37 is fixedly installed on the end of the push rod 35 away from the limiting piece 33, and the sealing plate 2 37 is slidably connected to the feed channel 4.

[0054] After the device completes the discharge, it is necessary to continue to crush other granular waste materials. At this time, the reciprocating screw 26 needs to continue to drive the moving cylinder 25 to move and make the sealing plate 28 and the discharge channel 6 seal. Then, the reciprocating screw 26 needs to continue to drive the moving cylinder 25 to move in the direction of the discharge channel 6, and in this process, the telescopic rod 27 is contracted. During the contraction of the telescopic rod 27, the sliding plate 24 will drive the extrusion member 29 to slide inside the fixed member 30, and during the movement of the extrusion member 29, the main airbag 31 will be squeezed and the main airbag 31 will transport gas to the inside of the auxiliary airbag 34 through the air pipe 32. The volume of the main airbag 31 is greater than the volume of the auxiliary airbag 34. At this time, the auxiliary airbag 34 will expand and push the push rod 35 to move. The process of the push rod 35 moving The second sealing plate 37 is then moved back to the original position, and the sealing plate 37 is moved back to the original position, so that the sealing plate 37 can be moved to the original position, so that the sealing plate 37 can seal the feed channel 4 and complete the feeding process.
