The liquid guiding groove 41 of the groove 40 is provided, and a piston column 72 for blocking the first liquid injection channel 22 is slidably arranged in the main channel 20, and when the piston column 72 slides into the main channel 20, the main crushing blade 9 is driven 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, so that the main channel 20 outside the piston column 72 is finally connected with the first liquid injection channel 22, so that the cooling medium provided by the refrigerator 70 merges with the cooling medium in the installation groove 40, so that the heat conductive cover plate 14 can provide a continuous supply of cold air for 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.

[0025] A driving motor 80 is provided on one side of the shell 1, and a pulley 81 is installed on the output end of the driving motor 80.

[0026] like Figure 6 and Fig. 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 an ejection spring 15 is provided at one end of the main crushing blade 9 close to the support shaft 2, and 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, and 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, and 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 conductive cover plate 14 emits cool air.

[0027] like Figure 7 As shown, a mounting groove 24 connected to the second 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 at one end close to the crushing roller sleeve 3, and the spherical part of the liquid guide tube 17 is wrapped with a rubber layer 18. The spherical surface of the liquid guide tube 17 is pushed by the elastic gasket 16 to fit tightly with the inner wall of the crushing roller sleeve 3, and is sealed by the rubber layer 18 to avoid leakage of the driving liquid in the main channel 20 during the process of entering the main liquid guide path 32 in the crushing roller sleeve 3 after passing through the secondary channel 21 and the second injection channel 23 in turn, 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 slide 30.

[0028] Embodiment 2: Figure 8 As 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 column 11 is fixed at one end of the connecting arm 10 away from the arc-shaped baffle 5, a slide groove 42 matching the slide column 11 is opened on the partition 4, and the bottom of the slide groove 42 is connected with the cooling groove 40, a compression spring 12 is provided at the upper end of the slide column 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 column 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 avoiding the leakage of cold air provided by the cooling component 7 out of the crushing chamber, and at the same time making the position of the arc-shaped baffle 5 more stable after stopping rotation.

[0029] Working principle: Before operation, the position of the arc-shaped baffle plate 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, and 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.

[0030] During operation, the plastic bottles to be crushed are loaded into the inner cavity of the shell 1 through the feed inlet, 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 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, so that the auxiliary crushing blade 6 on the arc baffle 5 and the main crushing blade 9 are sheared, and when the arc baffle 5 rotates with the partition 4 to the feed inlet and the discharge port for sealing When the gear is in gear, the electromagnetic telescopic rod 850 is energized by the encoder detecting the rotation angle of the support shaft, and the electromagnetic telescopic rod 850 drives the transmission gear 86 on the push-pull rod 851 to separate from the driving gear 84, so that the partition 4 stops rotating. At the same time, the refrigerator 70 injects cooling medium into the main channel 20, so that the cooling medium pushes the piston column 72 to squeeze the driving liquid inward to slide. The squeezed driving liquid passes through the secondary channel 21, the second liquid injection channel 23, the liquid guide cannula 17, the liquid guide main path 32 and the liquid guide branch path 31 in turn 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 bottle is not sheared and crushed, and only the plastic bottle in the inner cavity of the shell 1 is 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 plate 14 can continuously transfer 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 made of 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 mesh 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 broken bottle caps and anti-theft rings are discharged, and at the same time, the refrigerator 70 is used to recover 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, and 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.
