Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below with reference to specific embodiments:

[0025] First embodiment: Please refer to Figure 1-7A waste plastic bottle compression and recycling device includes a support frame 1, a cross-shaped cylinder 5 fixed on the support frame 1, a feed cylinder 15 installed on the top of the cross-shaped cylinder 5, a discharge pipe 4 installed on the bottom of the cross-shaped cylinder 5, a collection basket 3 arranged below the discharge pipe 4, an insert plate 9 slidably installed on the discharge pipe 4, and symmetrically arranged horizontal pressure columns I7 and II8 horizontally slidably installed inside the cross-shaped cylinder 5. An extension rod 6 is coaxially fixed on both horizontal pressure columns I7 and II8. The support frame 1 is equipped with... The feed cylinder 15 is equipped with a transmission box 13, on which a power assembly is installed to drive the horizontal pressure column I7 and the horizontal pressure column II8 to slide back and forth. A column 18 is vertically slidably installed on the feed cylinder 15. A vertical pressure column 27 that is vertically slidably connected to the cross cylinder 5 is fixed at the bottom end of the column 18. A storage basket 2 is fixed on the feed cylinder 15. A feeding channel 29 communicating with the storage basket 2 is opened on the feed cylinder 15. A baffle assembly for intermittently closing the feeding channel 29 is installed on the feed cylinder 15.

[0026] When this device compresses plastic bottles, the bottles are placed in the storage basket 2. After entering the feed cylinder 15, the bottles fall into the cross cylinder 5. Under the action of the power component, the horizontal pressure column I7 and the horizontal pressure column II8 move towards each other and compress the plastic bottles. By periodically pulling the insert plate 9 off the discharge pipe 4, the plastic bottles in the cross cylinder 5 can be easily discharged into the collection basket 3 for collection.

[0027] Specifically, the power assembly includes two coaxially fixed transmission bevel gears 21 rotatably mounted inside the transmission housing 13. A dual-axis motor 14 is fixed outside the transmission housing 13. One output shaft of the dual-axis motor 14 is coaxially fixed with an incomplete bevel gear 22 that alternately meshes with the two transmission bevel gears 21. A transmission assembly is installed between the transmission bevel gears 21 and the extension rod 6. The transmission assembly includes two sliding frames 10 horizontally slidably mounted on the support frame 1. The sliding frames 10 are fixed to the extension rod 6. A central gear 23 is coaxially fixed on the transmission bevel gears 21. Racks I11 and II12 are respectively meshed and connected to both sides of the central gear 23. Racks I11 and II12 are respectively fixed on the two sliding frames 10.

[0028] With the above setup, the dual-axis motor 14 drives the incomplete bevel gear 22 to rotate. The incomplete bevel gear 22 alternately meshes with the two transmission bevel gears 21. At this time, the transmission bevel gear 21 drives the central gear 23 to rotate clockwise and counterclockwise alternately. The central gear 23 simultaneously drives the rack I11 and rack II12 to move towards or away from each other alternately. Under the transmission action of the sliding frame 10 and the extension rod 6, the horizontal pressure column I7 and the horizontal pressure column II8 repeatedly press the plastic bottle.

[0029] In addition, a pull rod 17 is hinged between the column 18 and the two extension rods 6. When the extension rod 6 slides away from the cross cylinder 5, the pull rod 17 drives the column 18 to move vertically downward. When the extension rod 6 slides towards the cross cylinder 5, the pull rod 17 drives the column 18 to move vertically upward. This achieves the alternating horizontal and vertical squeezing action of the horizontal pressure column I7, the horizontal pressure column II8, and the vertical pressure column 27 on the plastic bottle, greatly improving the compression effect of the plastic bottle.

[0030] Second embodiment: Please refer to Figure 1-7 Based on the first embodiment, the baffle assembly of this device further includes a baffle plate 16 vertically slidably mounted on the feed cylinder 15. The baffle plate 16 slides in contact with the inner wall of the feed cylinder 15. An extension plate 25 is fixed on the baffle plate 16, and a guide rod 32 is fixed at the bottom of the extension plate 25. A sleeve plate 26 fixed on the storage basket 2 is sleeved on the guide rod 32. A vertical spring 24 is fixed between the sleeve plate 26 and the extension plate 25. The baffle assembly also includes a push block 28 fixed on the baffle plate 16. The push block 28 is slidably embedded in the vertical pressure column 27 in the vertical direction.

[0031] With the above settings, when the column 18 drives the vertical pressure column 27 to move vertically upward, and the vertical pressure column 27 moves to push the push block 28 upward, the baffle plate 16 overcomes the elastic force of the vertical spring 24 and moves vertically upward. At this time, the baffle plate 16 no longer blocks the feeding channel 29, and the plastic bottles inside the storage basket 2 can enter the feeding cylinder 15 along the feeding channel 29. Then the plastic bottles enter the cross cylinder 5 for compaction. The above process realizes the automatic feeding effect of plastic bottles and greatly improves the working efficiency of plastic bottle compaction and recycling.

[0032] In addition, another output shaft of the dual-axis motor 14 is coaxially fixed with a rotating shaft 20. Several deflectors 19 located in the storage basket 2 are fixed on the side wall of the rotating shaft 20. The rotating shaft 20 can drive the deflectors 19 to rotate, so that the deflectors 19 can push the plastic bottles in the storage basket 2 into the feeding cylinder 15, avoiding the plastic bottles from accumulating in the storage basket 2 and causing the feeding to be unsmooth, thus further improving the feeding effect of the plastic bottles.

[0033] Several piercing cones 31 are fixed on the horizontal pressure column I7, and several receiving holes 30 corresponding to the piercing cones 31 are fixed on the horizontal pressure column II8. When the horizontal pressure column I7 and the horizontal pressure column II8 move towards each other, the piercing cones 31 can pierce the plastic bottle. The receiving holes 30 are used for the piercing cones 31 to enter, so that the gas inside the plastic bottle can be discharged smoothly, which greatly improves the compression of the plastic.

[0034] In summary, this utility model achieves alternating and repetitive movements of the horizontal pressure columns I7 and II8 under the drive of the power component, thus fully compressing the plastic bottles inside the cross cylinder 5. The vertical pressure column 27 reciprocates vertically, achieving alternating vertical and horizontal compression of the plastic bottles, greatly improving the compression effect. The material blocking component can intermittently open the feeding channel 29, allowing the plastic bottles to automatically enter the cross cylinder 5 for intermittent feeding, greatly improving the compression and recycling efficiency of the plastic bottles.
