Description

Technical Field

[0001] This utility model specifically relates to an automatic separation and compression device for waste plastic bottle caps and bottles. Background Technology

[0002] With the rapid development of the plastics industry, plastic products are widely used in packaging, daily necessities, and other fields. Among them, plastic bottles are used extensively due to their lightweight and durability, resulting in a year-on-year increase in the number of waste plastic bottles. Recycling and reusing waste plastic bottles is an important measure to achieve resource recycling and reduce environmental pollution. In the recycling process of waste plastic bottles, separating the bottle cap from the bottle body is a crucial step. Since the bottle cap and bottle body are usually made of different types of plastics—for example, bottle caps are often made of polypropylene, while bottle bodies are often made of polyethylene terephthalate—failure to separate them will seriously affect the purity and quality of the subsequently recycled plastic, reducing its reuse value.

[0003] Currently, the separation of bottle caps from bottles in China mainly relies on manual sorting. Manual sorting is not only inefficient and unsuitable for large-scale recycling, but also labor-intensive and costly. Furthermore, some waste plastic bottles may contain corrosive liquids or harmful substances, posing safety hazards for manual sorting. Existing mechanical separation equipment is mostly complex in structure and cumbersome to operate, with poor adaptability to different sizes and shapes of plastic bottles, resulting in unsatisfactory separation and often incomplete separation of caps from bottles. In addition, after separation, the caps and bottles need to be compressed separately to reduce storage space and transportation costs, but existing equipment often fails to effectively combine separation and compression functions, leading to a cumbersome and inefficient recycling process.

[0004] Therefore, it is necessary to invent an automatic separation and compression device for waste plastic bottle caps and bottles to solve the above problems. Utility Model Content

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model provides, for example Figure 1-6 The device shown is an automatic separation and compression device for waste plastic bottle caps and bottles. It includes a conveying device 2 for conveying waste plastic bottles 1. Bottle cap separation device 3 and bottle body separation device 4 are respectively provided on both sides of the conveying device 2, and the two are positioned correspondingly. Specifically, the bottle cap separation device 3 includes a bottle cap separation collection box 31. The top and sides of the bottle cap separation collection box 31 are provided with cover plate assemblies 32. The bottle cap separation collection box 31 has a separation hole 33 on the side facing the conveying device 2. A clamping claw adjustment plate 34 is installed in the separation hole 33. Multiple evenly spaced clamping claws 35 are installed on the clamping claw adjustment plate 34. A push rod 36 is also provided in the middle of the clamping claw adjustment plate 34. The push rod 36 pushes the bottle cap 11 clamped in the clamping claws 35 into the bottle cap separation collection box 31. In this embodiment, the conveying device 2 continuously conveys the waste plastic bottle 1 to the separation station, ensuring that the plastic bottle passes through the corresponding area between the bottle cap separation device 3 and the bottle body separation device 4 in a stable posture.

[0020] Specifically, when the plastic bottle moves to the separation hole 33, the drive motor 38 inside the bottle cap separation and collection box 31 starts, driving the clamping claw adjustment plate 34 to rotate. The moving screw 342 inside the adjustment groove 341 rotates synchronously, adjusting the spacing of the clamping claws 35 through the moving sleeve 351 to adapt to bottle caps 11 of different sizes. The limiting plate 352 at the end of the clamping claw 35 wraps around the bottle cap 11 from both sides, and the clamping pad 353 at the bottom increases friction to prevent the bottle cap from slipping. After the clamping is stable, the push rod 36 extends along the push groove 343, peels the bottle cap 11 off the bottle body through the push plate 361, and pushes it into the bottle cap separation and collection box 31. The inclined surface design on the lower side of the separation hole 33 guides the bottle cap smoothly into the collection box, avoiding jamming.

[0021] Specifically, the bottle separation device 4 includes a bottle separation collection box 41, a conveyor 42 is installed on one side of the bottle separation collection box 41, and movable adjustment components 43 are provided on both sides of the top of the conveyor 42.

The clamping claw adjustment plate 34 has multiple evenly spaced adjustment grooves 341 on its surface. Moving screws 342 are installed on both sides of the inner wall of the adjustment grooves 341. Clamping claws 35 are installed on both sides of the moving screws 342. Matching moving sleeves 351 are provided on both sides of the clamping claws 35. The end of the clamping claws 35 extends to a limiting plate 352. A clamping pad 353 is provided at the bottom of the limiting plate 352. The bottle cap 11 is clamped together inside the multiple limiting plates 352.

[0023] In this embodiment, the bottle body 12 after the cap is separated continues to move with the conveying device 2 and is received by the conveyor belt 421 of the conveying platform 42. Inside the fixed frame 431 of the moving adjustment component 43, the adjusting screw 432 drives the moving block 441 of the clamping arm 44 to adjust its position laterally. The telescopic arm 442, in conjunction with the telescopic rod 443, adjusts the height and distance of the clamping plate 444. Finally, the clamping plates 444 on both sides stably clamp the bottle body 12 and move it to the inlet 411 of the bottle body separation collection box 41.

[0024] Specifically, the cover plate assembly 32 includes a cover plate 321, a hinge 322 is installed between one end of the cover plate 321 and the edge of the opening 37, and a handle is preferably provided on one side of the top of the cover plate 321.

[0025] Specifically, the clamping claw adjustment plate 34 has a push groove 343 in the middle for mounting the push rod 36, and a push plate 361 at the end of the push rod 36 covers the opening of the push groove 343.

[0026] Specifically, the top of the conveyor table 42 is provided with a conveyor belt 421, and the movable adjustment assembly 43 includes a fixed frame 431. An adjusting screw 432 is installed in the fixed frame 431. A clamping arm 44 is installed on the adjusting screw 432. The clamping arm 44 includes a moving block 441 that matches the adjusting screw 432. A telescopic arm 442 is provided on one side of the moving block 441. A telescopic rod 443 is provided at one end of the telescopic arm 442. A clamping plate 444 is installed at the end of the telescopic rod 443. The bottle body 12 is clamped between the two clamping plates 444.

[0027] Specifically, the bottle body separation collection box 41 has an inlet 411 on one side corresponding to the position of the conveyor 42, the bottle body separation collection box 41 has a top cover 412, the compression assembly 45 is installed on the rear side of the bottle body separation collection box 41, and the rear side of the bottle body separation collection box 41 has a matching compression hole 413.

[0028] Specifically, the compression assembly 45 includes a motor 451, one end of which extends a compression rod 452. A compression plate 453 is installed at the end of the compression rod 452. The compression plate 453 moves within the bottle separation and collection box 41 and compresses the bottle body separation and collection box 41 in conjunction with the inner wall of the bottle body separation and collection box 41.

[0029] In this embodiment, after the bottle body 12 enters the bottle body separation and collection box 41 through the inlet 411, the compression assembly 45 is activated. The motor 451 drives the compression rod 452 to move the compression plate 453 into the box along the compression hole 413, and squeezes and compresses the bottle body 12 in conjunction with the inner wall of the box to reduce its volume. After compression is completed, the compression plate is reset, waiting for the next batch of bottles to enter.

[0030] Specifically, the operator can open the cover 321 through the handle of the cover assembly 32 and take out the collected bottle caps from the opening 37 of the bottle cap separation collection box 31; similarly, the top cover 412 of the bottle body separation collection box 41 can be opened to clean up the compressed bottle body waste.

[0031] Specifically, the lower side of the separation hole 33 is set as an inclined surface.

[0032] In this embodiment, the spacing of the gripping claws 35 can be flexibly adjusted by moving the lead screw 342 to adapt to bottle caps of different sizes with diameters of 5-10cm, achieving a separation success rate of over 98%. Specifically, the combined design of the limiting plate 352 and the clamping pad 353 ensures that the bottle cap is not damaged during the peeling process, and avoids fragment residue affecting subsequent recycling. In this embodiment, the compression plate 453 of the compression assembly 45 can provide uniform pressure to compress the bottle volume, significantly reducing storage space occupation. During the compression process, the bottle body is subjected to balanced force, without the problem of fragments flying due to violent deformation.

[0033] Specifically, the device can be adapted to plastic bottles of different shapes and materials. The beveled design of the separation hole and the closed structure of the compression component reduce material jamming and operational risks, and improve the stability of equipment operation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
