Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically to a crushing and processing device for waste products from diaper production. Background Technology

[0002] The production of disposable diapers generates a large amount of substandard waste. Directly discarding this waste is not only environmentally unfriendly and wasteful, but it also risks being collected and resold by unscrupulous vendors, causing extremely negative social impacts. Therefore, most manufacturers shred waste diapers and then recycle the resulting fragments. This not only creates additional economic value but also aligns with environmental policies and the trend of sustainable development. However, disposable diapers have a multi-layered structure and are soft. Traditional shredders do not achieve uniform shredding results, requiring repeated shredding, which is time-consuming and labor-intensive. Furthermore, they lack fragment grading capabilities, hindering subsequent recycling and generating significant dust pollution. A new type of shredding equipment is needed to address these issues. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a waste crushing and processing device for diaper production, comprising a feeding belt, a pressing component above the feeding belt surface, an output end of the feeding belt connected to the upper feed inlet of a crushing box, a cutting component at the feed inlet, a crushing component in the middle of the crushing box, a coarse mesh cover connected to the lower discharge outlet of the crushing box, a fine mesh cylinder opening connected to the edge of the coarse mesh cover, a negative pressure pump connected to the bottom flange of the fine mesh cylinder, a filter connected to the output end of the negative pressure pump, a scraper motor located on the opposite side of the discharge outlet, the output shaft of the scraper motor passing through the center of the coarse mesh cover and extending to the fine mesh cylinder, the output shaft having a detachable scraper ring that engages with the cover mesh and the cylinder mesh.

[0004] Furthermore, the pressing assembly includes a pressing cylinder, both ends of which are rotatably connected to the upright arm of the feed belt output end side plate. A drive motor is installed on the outside of the upright arm, and the output end of the drive motor is connected to the drive roller of the feed belt. The gear at the end of the shaft of the drive roller meshes with the intermediate gear, and the intermediate gear meshes with the gear at the end of the shaft of the pressing cylinder.

[0005] Furthermore, the cutting assembly includes a lifting seat, with sliders on both sides of the lifting seat vertically slidingly connected to lifting grooves on both sides of the crushing box. A return spring is provided between the bottom of the lifting groove and the bottom surface of the slider. The bottom surface of the lifting seat is connected to the root of the gate knife. The blade of the gate knife cooperates with the anvil at the feed inlet. The center of the top surface of the lifting seat contacts the cam. The cam is connected to the cutting motor. The cutting motor is installed on the upper partition of the crushing box.

[0006] Furthermore, the crushing assembly includes crushing rollers, with the crushing teeth of the two crushing rollers interlocking. The roller shafts of the crushing rollers are rotatably connected to the side wall of the crushing box. The head end of the roller shaft of one of the crushing rollers is connected to a crushing motor, and the gears at the tail ends of the roller shafts of the two crushing rollers mesh through a transmission gear.

[0007] Furthermore, the scraper ring includes a ring body with a clearance fit between the inner diameter of the ring body and the output shaft diameter. The ring body is provided with several threaded through holes, which are threadedly connected to the threaded rod of the scraper. After the threaded rod is screwed out of the threaded through hole, it can tighten the output shaft body. The scraper is in contact with the cover mesh and the cylindrical mesh.

[0008] The beneficial effects of this utility model are as follows: After the pressing cylinder in the pressing assembly flattens the waste diapers, the diaper body is pre-cut into long strips by the reciprocating upper and lower guillotine blades, and then thoroughly crushed by two crushing rollers. The generated debris is graded by the coarse mesh cover and fine mesh cylinder under the drive of the negative pressure pump, which facilitates subsequent classification and processing. The cover mesh and cylinder mesh are cleaned by the scraper ring to prevent debris blockage. The fully enclosed crushing method reduces dust and has the characteristics of high efficiency and environmental protection. Attached Figure Description

[0018] The working principle of this utility model is as follows:

[0019] The drive motor 10 is started, which drives the feeding belt 1 and the pressing cylinder 9 to rotate. The feeding belt 1 transports the waste diapers to the bottom of the pressing cylinder 9 for flattening. The cutting motor 17 is started, which drives the cam 16 to rotate. The cam 16 drives the gate 14 to move up and down against the spring force of the return spring 13. The gate 14 and the anvil 15 cooperate to pre-cut the diapers into long strips of cloth. The strips fall into the crushing component and are crushed by the crushing roller 18. The airflow in the crushing box 2 is drawn in by the negative pressure pump 5 and carries the crushed material through the coarse mesh cover 3 and the fine mesh cylinder 4. Finally, it is discharged to the outside through the filter 6. During the flow, the larger and medium-sized crushed materials are cut off by the coarse mesh cover 3 and the fine mesh cylinder 4, respectively. The finest crushed materials are collected by the filter 6. During the crushing process, the scraper motor 7 drives the scraper ring 8 to rotate, cleaning the surface of the cover mesh and the cylinder mesh to prevent the crushed materials from clogging. Once the crushed material is collected, the negative pressure pump 5 can be removed, and the fine mesh cylinder 4, scraper ring 8, and coarse mesh cover 3 can be taken off to unload the crushed material at each level, which facilitates subsequent classification and processing. This method is characterized by high efficiency and environmental protection.
