Description

Technical Field

[0001] This invention relates to the field of plastic waste recycling and pretreatment technology, and in particular to a plastic woven bag recycling and reuse processing device and processing technology. Background Technology

[0002] Plastic woven bags are widely used for packaging bulk commodities such as cement, fertilizers, grains, and chemical raw materials due to their low cost, high strength, and good weather resistance. Most are for single use, resulting in a large number of discarded woven bags each year, most of which end up in landfills or incinerators, causing serious resource waste and environmental pollution.

[0003] With the development of the plastic recycling industry, the high-value recycling of plastic woven bags has become an industry trend. The pretreatment stage is the core factor determining the quality and recycling value of recycled polypropylene granules. The cleanliness and uniformity of the raw materials after pretreatment directly affect the mechanical properties and market value of the subsequent granulated products.

[0004] Currently, the drum-type pretreatment devices commonly used in the industry suffer from drawbacks such as easy tangling and knotting of materials, incomplete separation of impurities, and significant raw material loss. The processed recycled materials can only be used at a lower grade, significantly reducing the value chain. While some clamping-type pretreatment devices have shown improvement, they still suffer from poor versatility, unreliable material fixation, and low automation, making it difficult to meet the raw material requirements for high-quality recycled granulation and hindering the large-scale development of the plastic woven bag recycling industry.

[0015] This invention also provides a recycling and reuse process for plastic woven bags, using the above-mentioned processing apparatus, including the following steps: S1. Pre-processing and feeding: The recycled waste plastic woven bags are manually untied to remove large hard impurities such as nails, wires, and stones, and sorted into individual flat woven bags to be processed. The woven bags to be processed are placed on the feeding plate, and the lifting drive motor drives the feeding plate to rise to the loading and unloading station. The rangefinder detects the feeding height in real time to ensure that the feeding plate is level with the loading and unloading station. S2, Dual-station transfer and loading: The two sets of negative pressure adsorption components of the loading and unloading components work alternately. One set adsorbs the woven bags to be processed on the loading plate. After the rotary cylinder drives the woven bags to rotate and align, they are transferred to the conveyor slide. S3. Precise Conveying and Positioning: The conveying drive motor drives the conveying slide plate to move along the conveying guide rail to the preset position directly below the transfer component via the conveying screw and then stops. S4. Pre-treatment positioning and fixing: The vacuum nozzle of the transfer component adsorbs the woven bag on the conveying slide plate, transfers it into the washing tank and places it stably on the perforated plate. The flip telescopic cylinder drives the first flip rod and the second flip rod to rotate, so that the clamping head presses down to fix the two sides of the woven bag. S5. Multi-angle separation of complex materials: The transverse drive motor drives the pretreatment gantry to move back and forth along the guide rod through the transmission chain; the tilt angle of the pretreatment gantry is pre-adjusted according to the degree of contamination of the woven bag, the spray frame sprays the pretreatment liquid, and at the same time the pretreatment drive motor drives six sets of rotating brush heads to rotate synchronously to brush the woven bag in all directions. S6. Automated unloading and transfer: After the impurities are separated, the flip telescopic cylinder drives the clamping head to release, and the transfer component transfers the clean woven bag back to the conveying slide plate. Another set of negative pressure adsorption components of the unloading component adsorbs the clean woven bag and transfers it to the unloading plate. The lifting drive motor drives the unloading plate to descend to the discharge height, completing one processing cycle.

[0016] This invention provides a processing device and process for recycling and reusing plastic woven bags, which has the following beneficial effects: This invention achieves fully automated production of plastic woven bag recycling pretreatment through a dual-station automated loading, unloading, and transfer system. Two sets of negative pressure adsorption mechanisms work alternately, combined with a precise conveying and transfer system, eliminating the need for manual loading and unloading, significantly reducing labor intensity. At the same time, it achieves continuous production, greatly improving production efficiency compared to traditional devices, and can meet the production needs of large-scale plastic recycling and processing enterprises. Through the flat material handling method, it completely solves the industry common problem of material entanglement and knotting in traditional roller-type recycling pretreatment devices, avoiding raw material loss and equipment downtime caused by woven bags entangled during processing. The processed raw materials are in a single flat state, without entanglement or damage, and can directly enter the subsequent granulation process without additional manual sorting and secondary crushing, greatly simplifying the plastic recycling process.

[0017] This invention achieves universal compatibility with plastic woven bags of different specifications through an adjustable material fixing structure. The clamping spacing adjustment structure that can move back and forth, combined with the flexible adjustment of the left and right position of the clamping head, can be adapted to various lengths and widths of plastic woven bags on the market without the need to replace any clamps or parts, which greatly improves the utilization rate and applicability of the equipment and reduces the equipment investment cost of plastic recycling and processing enterprises.

[0018] This invention achieves reliable material fixation through a flip-type clamping and fixing mechanism, which can tightly press the woven bag onto the surface of the support plate, effectively preventing the woven bag from shifting, curling, or falling off during the recycling pretreatment process. This ensures that the impurity separation force is evenly applied to the entire surface of the woven bag, avoiding the problem of incomplete local treatment and significantly improving the uniformity and consistency of the quality of recycled raw materials.

[0019] This invention achieves effective and deep separation of stubborn impurities in the fiber texture of woven bags through a multi-angle reciprocating surface treatment structure. The reciprocating and angle-adjustable pretreatment gantry, combined with multiple sets of synchronously rotating surface treatment mechanisms, can separate impurities from woven bags in all directions without dead angles, effectively removing stubborn impurities such as oil and mud embedded in the fibers. The processed recycled raw materials have low ash content, which can meet the raw material requirements for high-quality polypropylene recycled granulation, realizing the high-value recycling and reuse of waste plastic woven bags.

Combined with the flexible adjustment of the left and right position of the clamping head 329, it can accommodate plastic woven bags of different specifications. The two flipping telescopic cylinders 328, respectively, drive the first flipping rod 325 and the second flipping rod 326 to rotate via the connecting head 327, thereby causing the clamping head 329 to press down and fix the front and rear edges of the woven bag, preventing the woven bag from falling. During the rotating brushing and high-pressure spraying process, the woven bags may shift, drift, or be lifted by the brush head, ensuring that the brushing and spraying forces are fully applied to the surface of the woven bags. The perforated plate 321 can catch solid impurities such as mud, sand, thread ends, and plastic fragments that fall during the treatment process, preventing impurities from clogging the drain pipe, while ensuring that the pre-treated waste liquid flows smoothly downward into the bottom tank 322. The inclined bottom surface of the bottom tank 322 allows the wastewater to quickly collect and discharge to one side of the drain pipe, preventing sewage from accumulating at the bottom of the tank and breeding bacteria, and facilitating subsequent wastewater filtration and recycling.

Pre-processing and feeding: The recycled waste plastic woven bags are manually untied to remove large hard impurities such as nails, wires, and stones, and sorted into individual flat woven bags to be processed. The woven bags to be processed are placed on the feeding plate 12. The lifting drive motor 114 drives the feeding plate 12 to rise to the loading and unloading station. The rangefinder 121 detects the feeding height in real time to ensure that the feeding plate 12 is level with the loading and unloading station. S2, Dual-station transfer and loading: The two sets of negative pressure adsorption components 145 of the loading and unloading component 14 work alternately. One set adsorbs the woven bags to be processed on the loading plate 12. After the rotary cylinder 1454 drives the woven bags to rotate and align, they are transferred to the conveying slide plate 162. S3. Precise conveying and positioning: The conveying drive motor 164 drives the conveying slide plate 162 to move along the conveying guide rail 161 to the preset position directly below the transfer component 22 through the conveying screw 163 and then stops. S4. Pre-treatment positioning and fixing: The vacuum nozzle 2251 of the transfer component 22 adsorbs the woven bag on the conveying slide plate 162, transfers it to the inside of the cleaning tank 32 and places it stably on the perforated plate 321. The flip telescopic cylinder 328 drives the first flip rod 325 and the second flip rod 326 to rotate, so that the clamping head 329 presses down to fix the two sides of the woven bag. S5. Multi-angle separation of complex materials: The transverse drive motor 313 drives the pretreatment gantry frame 34 to move back and forth along the guide rod 316 through the transmission chain 314; the tilt angle of the pretreatment gantry frame 34 is pre-adjusted according to the degree of contamination of the woven bag, the spray frame 343 sprays the pretreatment liquid, and at the same time the pretreatment drive motor 342 drives six sets of rotating brush heads 341 to rotate synchronously to brush the woven bag in all directions. S6. Automated unloading and transfer: After the impurities are separated, the flip telescopic cylinder 328 drives the clamping head 329 to release, and the transfer component 22 transfers the clean woven bag back to the conveying slide plate 162. Another set of negative pressure adsorption components 145 of the loading and unloading component 14 adsorbs the clean woven bag and transfers it to the unloading plate 13. The lifting drive motor 114 drives the unloading plate 13 to descend to the discharge height, completing one processing cycle.

[0045] The working principle of this embodiment is as follows: First, the waste plastic woven bags, which have been manually untangled, have had large hard impurities removed, and have been arranged into individual flat surfaces, are placed on the loading plate 12. The lifting drive motor 114 drives the vertical screw 113 to rotate, driving the loading plate 12 to rise along the vertical rail 111 and guide frame 112 to the loading / unloading station. The rangefinder 121 detects the loading height in real time to ensure that the loading plate 12 is precisely aligned with the loading / unloading station. The first telescopic cylinder 1142 of the loading / unloading component 14 drives the connecting plate 144, the first movable plate 142, and the second movable plate 143 to move synchronously along the rail 141 through the connecting block 1141. The second telescopic cylinder 1451 of the negative pressure adsorption component 145 drives the negative pressure adsorption component 145 to move synchronously along the rail 141. The suction nozzle 1457 descends to adsorb the woven bag, and the auxiliary stabilizing frame 1453 ensures a smooth and deflection-free adsorption process. The rotary cylinder 1454 rotates the woven bag to adjust its angle and then transfers it to the conveyor slide plate 162. The conveyor drive motor 164 drives the conveyor screw 163 to rotate, driving the conveyor slide plate 162 to move precisely along the conveyor guide rail 161 to directly below the transfer component 22. The rodless cylinder 222 of the transfer component 22 drives the moving block 223 to move smoothly laterally along the transverse rail frame 221. The third telescopic cylinder 224 drives the mounting frame 225 and the vacuum nozzle 2251 to descend and adsorb the woven bag, placing it stably on the perforated plate 321 inside the cleaning tank 32. The adjusting structure 3241 drives the moving seat. 324 moves back and forth along the guide slide bar 323 to adjust the clamping distance. The tilting telescopic cylinder 328 drives the first tilting rod 325 and the second tilting rod 326 to rotate synchronously through the connector 327, so that the clamping head 329 presses down to tightly press the woven bag onto the surface of the perforated plate 321. The transverse drive motor 313 drives the sliding seat 33 to move back and forth along the guide rod 316 through the gearbox 312 and the transmission chain 314, which in turn drives the pretreatment gantry 34 to move back and forth along the length of the cleaning tank 32. The adjusting bolt 334, in conjunction with the arc-shaped through groove on the mounting base 333, can flexibly adjust the tilt angle of the pretreatment gantry 34. The pretreatment drive motor 342 drives six sets of rotating brushes through the drive belt 3421. The brush head 341 rotates synchronously at high speed, and the pretreatment liquid sprayed by the spray frame 343 performs all-round, no-dead-angle brushing of the woven bag. The wastewater and impurities generated by brushing flow into the bottom box 322 through the hollow structure of the perforated plate 321. After being collected on the inclined bottom surface of the bottom box 322, they are discharged from the drain pipe. After the impurities are separated, the flip telescopic cylinder 328 drives the clamping head 329 to release. The transfer component 22 transfers the clean woven bag back to the conveying slide plate 162. Another set of negative pressure adsorption components 145 of the loading and unloading component 14 adsorbs the clean woven bag and transfers it to the unloading plate 13. The lifting drive motor 114 drives the unloading plate 13 to descend to the discharge height, completing a complete plastic woven bag recycling pretreatment processing cycle.
