Description

Technical Field

[0001] The invention belongs to the technical field of plastic bottle recycling, in particular to a PET plastic bottle recycling and crushing device. Background Art

[0002] PET plastic bottles, beverage packaging, are not only widely used to package carbonated beverages, drinking water, juice, enzymes and tea beverages, etc., but are the most widely used beverage packaging today. They are also widely used in many fields such as food, chemical, and pharmaceutical packaging, resulting in a large number of discarded PET plastic bottles. The recycling and reuse of PET plastic bottles can not only solve environmental problems, but also alleviate the problem of PET raw materials. In the recycling of PET plastic bottles, the plastic bottles need to be crushed, but the PET plastic bottle is composed of a PET bottle body, a PP bottle cap and a PP anti-theft ring, which requires splitting before crushing.

[0003] A Chinese invention patent publication numbered CN112549364A discloses a device for cutting, diverting, and collecting bottles and caps for waste recycling. The key technical features of the device include: a base and a cutting mechanism, with the cutting mechanism being mounted on the base; and a clamping mechanism, with the clamping mechanism being mounted on the cutting mechanism. The device utilizes both a cutting mechanism and a clamping mechanism, with the clamping mechanism capable of clamping the bottle body and separating the bottle body from the cap, thereby securing the bottle body for easy cutting. Furthermore, the device incorporates an automatic clamping and cutting mechanism, which cooperates with the cutting and clamping mechanisms, allowing the cylinder to drive the drive sleeve forward while simultaneously completing the cutting and clamping operations.

[0004] However, the above technology often has the following defects: First, in order to reduce transportation and storage space costs during the recycling process, people often flatten plastic bottles, which makes the shape of the bottles irregular and makes it difficult for the clamping mechanism to clamp them; second, although the device can separate the two different materials of the bottle body and the bottle cap, the anti-theft ring under the bottle cap will still remain at the bottle mouth of the plastic bottle.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1: Figures 1 to 6 As shown, a support shaft 2 is rotatably provided in the shell 1 of the embodiment of the present invention, a crushing roller sleeve 3 is fixedly provided on the outside of the support shaft 2, and a main crushing blade 9 is movably provided on the upper part of the crushing roller sleeve 3, a partition 4 is rotatably provided on the outside of the support shaft 2, and two partitions 4 are respectively located at the two ends of the crushing roller sleeve 3, and an arc-shaped baffle 5 for sealing the feed port and the discharge port is connected between the two partitions 4, and an auxiliary crushing blade 6 that shears with the main crushing blade 9 is fixed on the arc-shaped baffle 5, so that the main crushing blade 9 can be retracted or extended according to the needs of use, and it is convenient for later inspection, maintenance and replacement.

[0033] The two partitions 4 are provided with cooling grooves 40 on opposite sides, and the cooling grooves 40 are filled with a cooling medium. A heat-conducting cover 14 is fixed to the opening of the cooling grooves 40. A refrigerator 70 is installed on one side of the shell 1, and the output end of the refrigerator 70 is connected to a rotary joint 71 through a flexible hose. Both ends of the support shaft 2 are provided with main channels 20, and the main channels 20 are filled with a driving liquid, wherein the driving liquid can be a low-temperature resistant hydraulic oil. A secondary channel 21 connecting the two main channels 20 is provided in the support shaft 2, and a first injection channel 22 connecting the main channel 20 is provided on the outer side of both ends of the support shaft 2. A channel connecting the first injection channel 22 and the cooling medium is provided on the partition 4. The liquid guide groove 41 of the groove 40 is provided, and a piston column 72 for blocking the first liquid injection channel 22 is slidably provided in the main channel 20, and when the piston column 72 slides into the main channel 20, it drives the main crushing blade 9 to retract into the crushing roller sleeve 3, and the cooling medium is driven by the refrigerator 70 to push the sliding of the piston column 72, and finally the main channel 20 outside the piston column 72 is connected with the first liquid injection channel 22, so that the cooling medium provided by the refrigerator 70 is merged with the cooling medium in the installation groove 40, so that the heat conductive cover plate 14 can provide a steady stream of cold air to the inner cavity of the shell 1, and at the same time the piston column 72 pushes the driving liquid to flow to the secondary channel 21.

[0034] A driving motor 80 is provided on one side of the shell 1, and a pulley 81 is installed at the output end of the driving motor 80. A flywheel 82 is sleeved on the outer side of the end of the support shaft 2 close to the pulley 81, and the flywheel 82 and the pulley 81 are transmitted through a transmission belt 83. A driving gear 84 is fixedly installed on the outer side of one end of the support shaft 2, and a driven ring gear 87 is fixedly provided on the partition 4 close to the side of the driving gear 84. An electromagnetic telescopic rod 850 is fixedly provided on the shell 1 close to the side of the driving gear 84. The telescopic part of the electromagnetic telescopic rod 850 is connected to the push-pull rod 851, and the transmission gear 86 is rotatably set on the push-pull rod 851. An encoder 852 for detecting the rotation angle of the partition 4 is provided on the shell 1, and the encoder 852 is electrically connected to the electromagnetic telescopic rod 850. The rotation angle of the partition 4 is detected by the encoder 852, so as to determine that the arc-shaped baffle 5 is aligned with the feed port, so as to control the arc-shaped baffle 5 to accurately stop the rotation movement.

[0035] like Figure 6 and Figure 9 As shown, the main crushing blade 9 consists of a shearing portion 90 and a pressing portion 91, and stepped through grooves 30 for installing the main crushing blade 9 are evenly provided in the crushing roller sleeve 3, and a ejection spring 15 is provided at one end of the main crushing blade 9 close to the support shaft 2. A liquid guide branch 31 for connecting to the stepped through groove 30 is provided in the crushing roller sleeve 3, and a second liquid injection channel 23 connecting to the auxiliary channel 21 is provided on one side of the support shaft 2. A liquid guide main channel 32 connecting the liquid guide branch 31 and the second liquid injection channel 23 is provided on the inner wall of the crushing roller sleeve 3. The pressing portion 91 of the main crushing blade 9 is pushed by the driving liquid, so that the main crushing blade 9 retracts into the stepped through groove 30 when the heat-conducting cover plate 14 emits cool air.

[0036] like Figure 7 As shown, a mounting groove 24 connected to the second liquid injection channel 23 is provided on the outer side of the support shaft 2, and an elastic gasket 16 is provided in the mounting groove 24. A liquid guide tube 17 is provided on the upper end of the elastic gasket 16. The liquid guide tube 17 is spherical near one end of the crushing roller sleeve 3, and the spherical part of the liquid guide tube 17 is wrapped with a rubber layer 18. The elastic gasket 16 pushes the spherical surface of the liquid guide tube 17 to fit tightly with the inner wall of the crushing roller sleeve 3, and the rubber layer 18 is used to seal it to avoid leakage in the process of the driving liquid in the main channel 20 passing through the secondary channel 21 and the second liquid injection channel 23 and entering the main liquid guide path 32 in the crushing roller sleeve 3, thereby ensuring that the driving liquid can provide sufficient downward pressure for the downward pressure part 90 of the main crushing blade 9, so that the main crushing blade 9 can be smoothly retracted into the stepped chute 30.

[0037] Example 2: Figure 8As shown, compared with Example 1, another embodiment of the present invention is: connecting arms 10 are provided at both ends of the arc-shaped baffle 5, and a slide post 11 is fixed to the end of the connecting arm 10 away from the arc-shaped baffle 5, a slide groove 42 matching the slide post 11 is provided on the partition 4, and the bottom of the slide groove 42 is connected to the cooling groove 40, and a compression spring 12 is provided at the upper end of the slide post 11, and a limiting pressure plate 13 fixedly connected to the partition 4 is provided on the side of the compression spring 12 away from the slide groove 42, so that the cooling medium in the cooling groove 40 drives the slide post 11 to slide outward, and under the push of the connecting arm 10, the arc-shaped baffle 5 is tightly fitted with the inner wall of the shell 1, avoiding the occurrence of a gap between the arc-shaped baffle 5 and the inner wall of the shell 1, thereby preventing the cold air provided by the cooling component 7 from leaking out of the crushing chamber, and at the same time making the position of the arc-shaped baffle 5 more stable after it stops rotating.

[0038] Working principle: Before operation, the position of the arc-shaped baffle 5 does not block the feed port and the discharge port of the shell 1, and the piston column 72 is at one end close to the rotary joint 71, so that the first injection channel 22 is cut off by the piston column 72. At the same time, the main crushing blade 9 extends out of the crushing roller sleeve 3 under the action of the ejection spring 15 and the internal pressure of the liquid guide branch 31.

[0039] During operation, the plastic bottles to be crushed are loaded into the inner cavity of the shell 1 through the feed port, and the drive motor 80 is started, so that the output shaft of the drive motor 80 drives the pulley 81 to rotate, and through the transmission of the transmission belt 83, the flywheel 82 drives the support shaft 2 to rotate synchronously, so that the crushing roller sleeve 3 drives the main crushing blade 9 to rotate, and at the same time the support shaft 2 drives the driving gear 84 to rotate, and through the transmission gear 86, the driven gear ring 87 drives the partition 4 to rotate synchronously, thereby causing the auxiliary crushing blade 6 on the arc baffle 5 to shear with the main crushing blade 9. When the arc baffle 5 rotates together with the partition 4 to the feed port and the discharge port for sealing, When the gear is in gear, the electromagnetic telescopic rod 850 is energized by the encoder that detects the rotation angle of the support shaft. The electromagnetic telescopic rod 850 drives the transmission gear 86 on the push-pull rod 851 to separate from the driving gear 84, thereby stopping the rotation of the partition 4. At the same time, the refrigerator 70 injects cooling medium into the main channel 20, so that the cooling medium pushes the piston rod 72 to squeeze the driving liquid inward to slide. The squeezed driving liquid passes through the auxiliary channel 21, the second liquid injection channel 23, the liquid guide cannula 17, the liquid guide main channel 32 and the liquid guide branch channel 31 in sequence and enters the stepped barrel groove 30. The lower pressing part 91 of the main crushing blade 9 is pushed by the high-pressure driving liquid, so that the main crushing blade 9 squeezes The ejection spring 15 retracts into the crushing roller sleeve 3, so that the main crushing blade 9 no longer shears with the auxiliary crushing blade 6, so that the plastic bottles are not sheared and crushed, and only the plastic bottles in the inner cavity of the shell 1 are stirred. At the same time, the cooling medium finally passes through the main channel 20, the first liquid injection channel 22, and the liquid guide groove 41 and is connected with the cooling medium in the cooling groove 40, so that the heat-conducting cover 14 can continuously transmit cooling energy to the inner cavity of the shell 1. When the inner cavity temperature of the shell 1 is reduced to minus 41 degrees, the bottle cap and the anti-theft ring of the PP material undergo vitrification, so that the bottle cap and the anti-theft ring are quickly broken during the mutual squeezing process between the plastic bottles, and the electromagnetic The telescopic rod 850 is powered off, and the electromagnetic telescopic rod 850 drives the transmission gear 86 on the push-pull rod 851 to engage with the driving gear 84, so that the partition 4 drives the arc-shaped baffle 5 to rotate synchronously, so that the feed port and the discharge port are no longer closed all the time, so that the crushed bottle caps and anti-theft rings are discharged. At the same time, the refrigerator 70 is used to recycle the cooling medium, so that the piston column 72 is reset and slid, so that the driving liquid in the stepped groove 30 flows to the main channel 20. At the same time, under the joint action of the elastic force of the ejection spring 15, the main crushing blade 9 extends out of the crushing roller sleeve 3, so that the unbroken bottle body is crushed under the shear between the main crushing blade 9 and the auxiliary crushing blade 6.
