Waste plastic bottle piece recycling and crushing equipment

Abstract

The invention discloses waste plastic bottle piece recycling and crushing equipment, relates to the technical field of plastic recycling, and aims to solve the problems that beverage bottles are most common in current waste plastic bottles, the surfaces of the beverage bottles are smooth bottle bodies, and meanwhile, the plastic bodies have the deformation characteristic, so that the beverage bottles cannot be crushed easily in the material flattening and shearing process of a crusher. Due to the fact that a smooth bottle body slips relative to equipment and cannot be crushed and compressed, shearing force exists between the pressing reels through staggered rotation between the pressing reels on the two sides, entering plastic bottle pieces are cut into small pieces, and meanwhile the plastic bottle pieces are compressed through the spiral grooves formed in a spiral mode when the plastic bottle is compressed. The heights of the two ends of the plastic bottle are different due to the fact that the contact positions of the plastic bottle and the material pressing reels are different, the lower end is firstly compressed, meanwhile, the first compressed end is cut into a notch through shearing force between the material pressing reels on the two sides, and the situation that the smooth plastic bottle slips during compression and cannot be broken is avoided.

[0018] The third embodiment is based on the first and second embodiments. Figures 7 and 8 As shown, the crushing mechanism 3 includes a fixed side plate 301 and a fixed column 309, the fixed side plate 301 is fixedly connected to the inner wall of the crushing bin 1, both ends of the fixed column 309 are rotatably connected to the inner wall of the crushing bin 1, and the fixed column 309 is symmetrically installed along the center position of the axis of the crushing bin 1, and one end of the fixed column 309 is fixedly connected to the output end of the crushing motor 6. After compression and separation, the plastic bottle pieces become small pieces of plastic pieces, which fall from the bottom of the pressing mechanism 2 and enter the top of the fixed column 309. The fixed column 309 is driven by the crushing motor 6 to rotate inward at the same time, and the top plastic piece is moved to the center position. The outer side of the fixed column 309 is fixedly connected with an insulating cylinder 310, and the outer side of the insulating cylinder 310 is fixedly installed with a crushing knife ring 311. The outer side of the crushing knife ring 311 is evenly provided with cutting grooves. In the process of driving, the insulating cylinder 310 is driven by the fixed column 309, so that the insulating cylinder 310 drives the outer crushing knife ring 311, and the crushing knife rings 311 on both sides shear and crush the plastic sheets pressed into the center position through the crushing groove, so that the waste plastic bottle sheets are completely crushed and then discharged from the discharge port at the bottom of the crushing bin 1, and the crushing knife rings 311 are evenly installed on the outer side of the insulating cylinder 310.

[0019] There are two fixed side plates 301, and both ends of the opposite surfaces of the fixed side plates 301 are installed with limit blocks 302, and the outer side of the limit block 302 is provided with an adjustment groove 308, and a sliding plate 305 is slidably installed at the adjustment groove 308, and an arc-shaped push plate 303 is fixedly installed on the opposite surface of the sliding plate 305, and the top of the arc-shaped push plate 303 is in contact with the outer side of the pressure reel 203, and the bottom of the arc-shaped push plate 303 is in contact with the outer side of the crushing knife ring 311. When the crushing knife ring 311 is used for complete crushing, the fixed side plate 301 is restricted between the pressure reel 203 and the crushing knife ring 311, and the sliding plate 305 is pushed by the elastic gasket 306, so that the sliding plate 305 pushes the arc-shaped push plate 303, so that the upper part of the arc-shaped push plate 303 The lower two sides are in contact with the outer sides of the pressure reel 203 and the crushing knife ring 311 respectively to block the material and prevent it from falling from both sides. Elastic washers 306 are fixedly installed at both ends of the sliding plate 305 away from the arc-shaped push plate 303. A cleaning trough block 304 is fixedly installed on the top of the arc-shaped push plate 303. The cleaning trough block 304 is evenly installed on the top of the arc-shaped push plate 303 and is located between the pressure reel 203. A push rod groove 307 is provided at the top center of the cleaning trough block 304. When the hollow groove cylinder 210 drives the piercing rod 205 to rotate, the cleaning trough block 304 on the top of the arc-shaped push plate 303 cleans between the pressure reel 203, and at the same time, the piercing rod 205 is squeezed inwardly through the push rod groove 307 to deform the elastic gasket 207.

[0020] When in use, a worker introduces waste plastic bottle pieces into the crushing bin 1 from the feeding port at the top of the crushing bin 1, drives the pressing mechanism 2 to operate through the pressing motor 4, guides the introduced plastic bottle pieces to the center position of the pressing mechanism 2 through the guide block 5, flattens the plastic bottle pieces through the pressing mechanism 2, and cuts them into small pieces. The flattened and cut plastic falls from the bottom of the pressing mechanism 2, and is driven by the crushing motor 6 to operate the crushing mechanism 3, so that the plastic is completely crushed and discharged from the discharge port at the bottom of the crushing bin 1.

[0021] When the material is flattened and shredded by the pressing mechanism 2, the pressing motor 4 drives one of the hollow grooved cylinders 210 to rotate through the connecting disk 201, and the other hollow grooved cylinder 210 is driven to rotate through the meshing between the toothed rings 202 on the outside of the connecting disk 201. The plastic bottle flakes on the upper layer of the hollow grooved cylinder 210 are compressed and cut by the pressing reels 203 on the outside of the hollow grooved cylinders 210 on both sides. At the same time, during the rotation of the pressing reel 203, the closed plastic is clamped and compressed from one side through the cooperation of the spiral groove 209. During the compression process, the bottle body is broken by the staggered pressing of the pressing reels 203 on both sides, and the shear force between the pressing reels 203 divides the plastic bottle flakes into small pieces.

[0022] During the process of the pressing reel 203 rotating alternately to compress and shear the plastic bottle flakes, the hollow groove cylinder 210 drives the internal inner support column 204 to rotate, so that the inner support column 204 cooperates with the connecting groove block 208 through the elastic gasket 207, and cooperates with the perforation of the hollow groove cylinder 210, driving the piercing rod 205 to rotate together with the pressing reel 203, and the piercing rod 205 will pierce the plastic bottle or the plastic sheet through the sharp spikes at the front end. During the piercing process, the closed plastic bottle will be notched to release the air in the bottle, thereby assisting the pressing reel 203 in compressing the plastic bottle flakes.

[0023] After compression and separation, the plastic bottle flakes become small pieces of plastic flakes, which fall from the bottom of the pressing mechanism 2 and enter the top of the fixed column 309. The fixed column 309 is driven by the crushing motor 6 to rotate inward at the same time, and the plastic flakes on the top are driven toward the center position. In the process of driving, the insulation cylinder 310 is driven by the fixed column 309, and the insulation cylinder 310 drives the outer crushing knife ring 311. The crushing knife rings 311 on both sides shear and crush the plastic flakes pressed into the center position through the crushing groove, so that the waste plastic bottle flakes are completely crushed and then discharged from the discharge port at the bottom of the crushing bin 1.

[0024] When the crushing knife ring 311 is used for thorough crushing, the fixed side plate 301 is restricted between the pressure reel 203 and the crushing knife ring 311, and the sliding plate 305 is pushed by the elastic gasket 306, so that the sliding plate 305 pushes the arc-shaped push plate 303, so that the upper and lower sides of the arc-shaped push plate 303 are respectively in contact with the pressure reel 203 and the outer side of the crushing knife ring 311, so as to block the material and prevent the material from falling from both sides. At the same time, when the hollow groove cylinder 210 drives the piercing rod 205 to rotate, the cleaning groove block 304 on the top of the arc-shaped push plate 303 cleans between the pressure reel 203, and at the same time, the piercing rod 205 is squeezed inwardly through the push rod groove 307, so that the elastic gasket 207 is deformed.
