Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a multi-stage crushing device for raw materials of plastic woven bags. Background Technology

[0002] The raw materials used in the processing of plastic woven bags are mostly recycled waste plastic products. When processing plastic products, the raw materials need to be crushed, which requires the use of corresponding crushing devices. Chinese utility model patent, authorized announcement number "CN222245625U", discloses a multi-stage crushing device for plastic woven bag raw materials. The multi-stage crushing device for plastic woven bag raw materials of this application uses crushing rollers to initially crush the recycled plastic products into smaller plastic pieces, and then uses crushing blades to crush them, which can significantly improve the crushing effect, while greatly reducing the wear and tear on the blades, thus protecting the blades and extending their service life.

[0003] During the use of the above-mentioned technical solution, due to the toughness and stickiness of the plastic woven bag raw material, the raw material is easy to adhere to the surface of the crushing roller during the crushing process. The material adhering to the crushing roller will occupy the working surface of the crushing roller, and the material adhering to the crushing roller will cause uneven distribution of crushing force, resulting in uneven particle size distribution of the crushed raw material. Some raw materials may not be fully crushed, while others may be over-crushed, which seriously affects the quality stability of the plastic woven bag raw material and thus affects the performance of the final product. Therefore, we propose a multi-stage crushing device for plastic woven bag raw materials. Utility Model Content

[0026] Please see Figure 1-4 This utility model provides a technical solution: a multi-stage crushing device for plastic woven bag raw materials, comprising:

[0027] Woven bag raw material crushing box 1, with a feed top cover 17 fixedly installed on the top of the woven bag raw material crushing box 1;

[0028] The crushing and cleaning structure is located on the woven bag raw material crushing box 1.

[0029] The crushing and cleaning structure includes a drive motor 2, two crushing rollers 9, two rotating shafts 13, two gears 7, and two cleaning brush cylinders 10. The two rotating shafts 13 and the two cleaning brush cylinders 10 are rotatably connected inside the woven bag raw material crushing box 1. The two crushing rollers 9 are fixedly sleeved on the outer surface of the corresponding rotating shafts 13. The drive motor 2 is fixedly installed on one side of the woven bag raw material crushing box 1. The output end of the drive motor 2 extends rotatably into the interior of the woven bag raw material crushing box 1 and is fixedly connected to the corresponding rotating shaft 13. The ends of the two rotating shafts 13 and the two cleaning brush cylinders 10 away from the drive motor 2 extend rotatably to the outside of the woven bag raw material crushing box 1. The two gears 7 are fixedly sleeved on the outer surface of the corresponding rotating shafts 13 and are meshed. Multiple air jet holes 16 are opened on the outer surface of the two cleaning brush cylinders 10.

[0030] The crushing and cleaning structure also includes a blower 6, a filter cover 12, two synchronous belts 14, and an air supply pipe 8. Synchronous pulleys 15 are fixedly sleeved on the outer surfaces of the two rotating shafts 13 and the two cleaning brush cylinders 10. The two synchronous belts 14 are driven and sleeved on the outer surfaces of the corresponding two synchronous pulleys 15. The blower 6 is fixedly installed on the side of the woven bag raw material crushing box 1 away from the drive motor 2. The filter cover 12 is threadedly sleeved on the air intake end of the blower 6. The exhaust end of the blower 6 is fixedly connected to the air supply pipe 8. The two ends of the air supply pipe 8 away from the blower 6 are located inside the corresponding cleaning brush cylinders 10. The interior of the two cleaning brush cylinders 10 is rotatably and sealingly connected to the outer surface of the air supply pipe 8.

[0031] There are two crushing and cleaning structures, which are arranged in a linear array inside the woven bag raw material crushing box 1. Four guide plates 11 are fixedly connected inside the woven bag raw material crushing box 1, and the four guide plates 11 are all located above the corresponding crushing rollers 9.

[0032] The woven bag raw material crushing box 1 is equipped with a vibrating screen plate 5. The woven bag raw material crushing box 1 has a discharge port 4 on the side away from the drive motor 2. The discharge end of the vibrating screen plate 5 is located inside the discharge port 4. The woven bag raw material crushing box 1 has a feeding port 3 on the side close to the drive motor 2.

[0033] Furthermore, when using this device, if it is necessary to crush the plastic woven bag raw material, the drive motor 2 is started. The drive motor 2 drives the corresponding rotating shaft 13 to rotate. Since the two gears 7 are respectively fixedly sleeved on the outer surface of the corresponding rotating shaft 13 and mesh with each other, when one rotating shaft 13 rotates, through the transmission action of the gear 7, the other rotating shaft 13 will rotate in the opposite direction, so that the two crushing rollers 9 rotate in opposite directions to crush the plastic woven bag raw material. The plastic woven bag raw material is put into the woven bag raw material crushing box 1 from the feed top cover 17. The raw material falls under its own gravity and is guided by the guide plate 11 into the space between the two crushing rollers 9. The crushing rollers 9 rotate relative to each other to squeeze and shear the raw material, thus achieving preliminary crushing.

[0034] The device is equipped with two linearly arrayed crushing and cleaning structures. After the first stage of crushing, the raw material continues to fall and enters the crushing rollers 9 in the second stage of crushing and cleaning structure for further crushing, thereby achieving multi-stage crushing and ensuring that the raw material is fully pulverized.

[0035] The rotation of the two rotating shafts 13 will drive the corresponding cleaning brush cylinders 10 to rotate under the transmission of the synchronous pulley 15 and the synchronous belt 14. During the rotation of the two cleaning brush cylinders 10, the bristles on their surfaces will brush the surface of the crushing roller 9, cleaning off the raw materials that adhere to the crushing roller 9 during the crushing process, preventing the accumulation of raw materials from affecting the crushing effect. At the same time, the exhaust fan 6 is started. After the outside air is filtered by the filter cover 12, it is drawn in by the exhaust fan 6 and delivered to the air supply pipe 8 through the exhaust end. After the air enters the cleaning brush cylinder 10 from the air supply pipe 8, it is ejected from the multiple air jet holes 16 on the outer surface of the cleaning brush cylinder 10, forming a high-pressure airflow. The high-pressure airflow further blows the surface of the crushing roller 9, blowing off the fine particles remaining after brushing and cleaning, achieving a more thorough cleaning.

[0036] After being crushed and cleaned in multiple stages, the raw materials fall onto the vibrating screen plate 5. The vibrating screen plate 5 screens the raw materials through vibration. The raw materials that meet the particle size requirements fall through the screen holes of the vibrating screen plate 5 and are discharged from the discharge port 3. The raw materials that do not meet the particle size requirements are discharged from the discharge port 4 under the guidance of the vibrating screen plate 5.

[0037] By combining the brushing cleaning of the cleaning brush cylinder 10 with the air jet cleaning of the air jet hole 16, the raw materials adhering to the surface of the crushing roller 9 can be removed in a timely and thorough manner. This avoids the problems of uneven crushing force and reduced crushing efficiency caused by the adhesion of raw materials, ensuring the continuity and stability of the crushing process and further improving the crushing efficiency.
