[0002] This disclosure claims priority to Chinese Patent Application No. 202411563478.5, filed on November 5, 2024, entitled "A Plastic Bottle Compression and Recycling Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of plastic bottle recycling technology, and in particular to a plastic bottle compression and recycling device. Background Technology

[0004] A plastic bottle recycling machine is a specialized device for recycling plastic bottles. It uses automation technology to help reduce the environmental impact of plastic waste. Currently, common methods for recycling plastic bottles mainly include manual sorting and simple mechanical recycling. Manual sorting is inefficient, costly, and difficult to guarantee accurate classification. While mechanical recycling equipment can improve recycling efficiency, most equipment lacks intelligent identification functions and cannot effectively classify plastic bottles of different materials, resulting in low purity of recycled materials and affecting subsequent reuse. Large-sized plastic bottles take up space during recycling, making subsequent packaging and transportation inconvenient. Furthermore, existing equipment still suffers from problems such as high reliance on manual labor, low compression efficiency, high compressor noise, and insufficient safety, making it unsuitable for direct market supply to consumers.

[0047] Optionally, a material identification module is detachably connected to the housing 1 above the feeding section 5; the material identification module is electrically connected to the controller 8; a photoelectric sensor 28 is detachably connected to the upper part of the compression chamber 2. The material identification module uses a Raman spectrometer to detect the material and feeds the detection results back to the controller 8; the photoelectric sensor 28 can detect the height of the plastic bottle inside the compression chamber 2, and when the height reaches a predetermined position, the controller 8 controls the extrusion section 4 to move and compress the plastic bottle.

[0048] Optionally, the compression chamber 2 includes a chamber shell 21, an ejection assembly 22, a chamber door 23, a first electric push rod 24, and a magnetic suction plate 25; the chamber shell 21 has a vertically opened through slot 29 configured to fit the binding part 3; the ejection assembly 22 is provided at the rear end of the chamber shell 21, and the chamber door 23 is rotatably connected to the front end; the tail end of the first electric push rod 24 is detachably connected to the side where the chamber door 23 is rotatably connected to the chamber shell 21, and the output end is detachably connected to the end face of the chamber door 23; the magnetic suction plate 25 is provided on the side away from the chamber door 23, configured to fix the chamber shell 21 and the chamber door 23; the ejection assembly 22 includes a second electric push rod 221, a push plate 222, a sleeve 223, and a guide rod 224; the output end of the second electric push rod 221 is detachably connected to the push plate 222; the upper and lower ends of the push plate 222 are fixedly connected to the guide rod 224; the sleeve 223 is slidably sleeved on the guide rod 224; the sleeve 223 is fixedly connected to the chamber shell 21.

[0050] The second electric push rod 221 provides power support for pushing out the plastic bottle; the push plate 222 is a vertical plate that can effectively ensure greater contact with the plastic bottle, so that it can be pushed out effectively; the sleeve 223 cooperates with the guide rod 224 to prevent the second electric push rod 221 and the push plate 222 from tilting during the movement.

[0051] Optionally, the transmission unit 6 includes a connecting frame 61, a fixed guide rail 62, a sliding guide rail 63, a first motor 64, a driven wheel 65, and a rack 66; the connecting frame 61 is fixedly connected to the first support member 26 at the upper end of the compression chamber 2; the fixed guide rail 62 is detachably connected to the lower part of the first support member 26; the sliding guide rail 63 is slidably connected to the fixed guide rail 62; a clamp 67 is fixedly connected to the lower part of the sliding guide rail 63; the first motor 64 is detachably connected to the upper part of the connecting frame 61; the driven wheel 65 is fixedly connected to the output end of the first motor 64; the rack 66 is fixedly connected to the side of the sliding guide rail 63 through an L-shaped plate; the driven wheel 65 can move relative to the rack 66.

[0052] The connecting frame 61 facilitates a stable connection between the transmission unit 6 and other components; the fixed guide rail 62 can be fixed to the connecting frame 61; the sliding guide rail 63 can move relative to the fixed guide rail 62, driving the clamp 67 to move and grab the plastic bottle into the compression chamber 2; the first motor 64 can drive the driven wheel 65, causing the rack 66 to move. The rack 66 is fixed to the side of the sliding guide rail 63 by an L-shaped plate, and the sliding guide rail 63 can be driven to move by the first motor 64.

[0053] Optionally, the transmission section 6 provided in this embodiment further includes a rectangular protrusion 68 and an arc-shaped protrusion 69; the rectangular protrusion 68 is detachably connected to the lower end of the U-shaped support frame 27; the arc-shaped protrusion 69 is detachably connected to the lower end of the extrusion section 4; the front end of the first support member 26 is detachably connected to the U-shaped support frame 27; the clamp 67 includes a limiting member 671, a clamping plate 672, a transverse connecting member 673, and a spring 674; the limiting member 671 contacts the inner side of the rectangular protrusion 68 when the clamp 67 moves toward the feeding section 5, and moves away from the feeding section 5. When moving away from the feed section 5, it contacts the outer side of the rectangular protrusion 68; two transverse connecting members 673 are detachably connected between the two clamping plates 672; a spring 674 is detachably connected between the clamping plate 672 and the transverse connecting member 673; a limiting member 671 is located above the clamping plate 672 on one side of the rectangular protrusion 68, configured to realize the opening and closing of the clamp; when the clamp 67 moves upward towards the compression cavity 2, the limiting member 671 contacts the arc surface of the arc-shaped protrusion 69, configured to realize the opening and closing of the clamp 67.

[0054] The small side of the rectangular protrusion 68 is parallel to the moving direction of the sliding guide rail 63. When the limiting member 671 passes the rectangular protrusion 68, it contacts the inner side of the rectangular protrusion 68 as the clamp 67 moves towards the feeding section 5, and the spring 674 is stretched. At this time, the clamp 67 changes from the clamping state to the open state. When it disengages from the rectangular protrusion 68, the spring 674 contracts, so that the clamping plate 672 just clamps the plastic bottle. Then the controller 8 reverses, driving the rack 66 to move away from the feeding section 5. At this time, the limiting member 671 contacts the outer side of the rectangular protrusion 68. The limiting member 671 is in an active state and does not exert force on the clamp 67. The clamp 67 still maintains the clamping state. After the clamp 67 moves above the compression chamber 2, the limiting member 671 just contacts the arc surface of the arc-shaped protrusion 69. The spring 674 is stretched, so the clamp 67 changes to the open state, and the plastic bottle falls into the compression chamber 2. The clamp 67 completes one clamping process.

[0055] Optionally, an arc-shaped groove 675 is provided below the gripping plate 672; the arc-shaped groove 675 can effectively grip plastic bottles of different sizes. The arc-shaped groove 675 is serrated or fitted with a rubber sheet; the serrated shape or the rubber sheet allows for more stable gripping of plastic bottles. The feeding section 5 is an arc-shaped plate that matches the shape of the conveying section 6; the discharging section 7 is an inclined U-shaped splicing plate. The arc-shaped plate and the U-shaped splicing plate are designed to facilitate feeding and discharging.

[0056] Optionally, the strapping part 3 is a strapping machine or a packing machine; strapping machines or packing machines are existing technologies, and those skilled in the art can select a suitable strapping machine or packing machine to embed into the compression cavity 2 for use as needed.

[0057] Optionally, the extrusion section 4 provided in this embodiment includes a second motor 41, a belt 42, a drive shaft 43, a first lead screw 44, a second lead screw 45, a first pressure plate 46, and a second pressure plate 47. The output end of the second motor 41 drives the first lead screw 44 to move up and down via a worm gear. The output end of the second motor 41 is connected to the drive shaft 43 via the belt 42. The drive shaft 43 drives the second lead screw 45 to move up and down via a worm gear. The lower end of the first lead screw 44 is fixedly connected to the first pressure plate 46. The lower end of the second lead screw 45 is fixedly connected to the second pressure plate 47. The first pressure plate 46 and the second pressure plate 47 are on the same horizontal plane, and a gap 48 is left between them to accommodate the upper frame 31 of the binding section 3. A pressure sensor is provided below the first pressure plate 46 and the second pressure plate 47.

[0058] The second motor 41 drives the first lead screw 44 and the second lead screw 45 to move up and down through a worm gear and a belt drive, thereby compressing the plastic bottles that need to be compressed in the compression chamber 2, so as to ensure that there is still space inside the compression chamber 2 to place and compress subsequent bottles; the pressure sensor can detect the pressure and transmit it to the controller 8.

[0059] Optionally, a collection port 9 is provided on the housing 1 near the feed inlet 12; inside the housing 1, a collection trough 91 is fixedly connected below the collection port 9; a display 10 is provided on the housing 1, and the display 10 is electrically connected to the controller 8.

[0060] The collection port 9 and the collection trough 91 work together to collect bottle caps and other debris in the early stages of plastic bottle recycling; the display 10 is a commercially available product, which can be selected by those skilled in the art according to actual needs. It can display the number of plastic bottles, and can also be designed as an interactive scene to increase fun and encourage users to put plastic bottles into the device.

[0061] Optionally, a turntable 32 is rotatably connected to the U-shaped support frame 27 above the transmission section 6, configured to hold the strapping straps; the turntable 32 facilitates the placement of the strapping straps. Several pulleys 33 are fixed to the outer wall of the compression chamber 2 to facilitate the movement of the strapping straps.

[0062] The working principle of this disclosure embodiment:

[0063] First, the plastic bottles to be recycled are put into the feed inlet 12. When the plastic bottles reach the feed section 5, the material identification module set above the feed section 5 identifies the material. If the material is a recyclable plastic bottle, the controller 8 controls the transmission section 6 to clamp the plastic bottle placed on the feed section 5. After clamping, the transmission section 6 moves above the compression chamber 2 and then opens, and the plastic bottle falls smoothly into the compression chamber 2, thus completing one plastic bottle feeding process.

[0064] Detected by the controller 8, when the photoelectric sensor 28 detects that the bottles placed in the compression chamber 2 have reached the set height or the material identification module identifies that the number of plastic bottles has reached the predetermined number, the controller 8 controls the clamp of the transmission unit 6 to move above the feeding unit 5, and then starts the extrusion unit 4 to compress the stacked plastic bottles in the compression chamber 2, reducing the stacking space to ensure the subsequent input of plastic bottles. When the number of plastic bottles input reaches the set number, the controller 8 controls the extrusion unit 4 to extrude the stacked plastic bottles while controlling the bundling unit 3 to bundle and pack the stacked plastic bottles. After the packing is completed, the extrusion unit 4 rises back to its original position, the first electric push rod 24 retracts and drives the chamber door 23 to open, and the second electric push rod 221 drives the push plate 222 to extend, pushing out the bundled and packed plastic bottles. The bundled plastic bottles slide out through the discharge unit 7 and are recycled by the staff.

[0065] The embodiments of this disclosure have been described in detail above with reference to the accompanying drawings, but this disclosure is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this disclosure, and these variations still fall within the protection scope of this disclosure.
