Description

Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a crushing device for degradable plastic woven bags. Background Art

[0002] Plastic woven bags are currently a packaging material widely used for items such as fertilizers and chemical products. After some woven bags are used, they may be directly scrapped after one use due to reasons such as being broken or contaminated by the materials they contain and being unable to be used again. These scrapped woven bags may be directly discarded, causing environmental pollution, or they may be recycled, crushed, and reused. Therefore, in order to avoid environmental pollution, many manufacturers now use environmentally degradable plastics for the production of woven bags.

[0003] When recycling and processing these scrapped degradable plastic woven bags, crushers or shredders are needed. For the existing Chinese utility model patent with the publication number CN220657736U and the name of a waste woven bag crushing and cleaning device, its crushing mechanism includes a closed housing and a rolling chamber and a crushing chamber arranged inside the housing. When the rolling wheels in the rolling chamber are working, they play the functions of rolling and feeding materials to the crushing chamber. The woven bags are stacked in the channel between the rolling wheels and the rolling chamber. The woven bags close to the rolling wheels can be rolled and fed, but the woven bags close to the inner wall of the rolling chamber are difficult to be rolled and fed, often resulting in unsmooth operation. In addition, the pair of crushing wheels in the crushing chamber have a general crushing effect on soft woven bags, and the woven bags will move together with the rotation of the crushing wheels, resulting in a reduced crushing effect. Content of the Utility Model

[0027] In this embodiment, Figure 1 , Figure 2 and Figure 3 as shown, a degradable plastic woven bag crushing device includes a housing 1, a feeding roller 2, a crushing roller 3 and a motor 4. The housing 1 is divided into a feeding bin 5 and a crushing bin 6 communicating with the discharging port at the bottom of the feeding bin 5. The feeding roller 2 and the crushing roller 3 are respectively rotatably installed in the feeding bin 5 and the crushing bin 6. The power output ends of the two motors 4 are respectively connected to the power input ends of the feeding roller 2 and the crushing roller 3. Among them, a feeding channel 7 for preventing the woven bag from running off is formed between the feeding bin 5 and the feeding roller 2.

[0028] Start the two motors 4 to drive the feeding roller 2 and the crushing roller 3 to rotate in the same direction respectively. The plastic woven bag is put into the feeding port of the housing 1 and enters the feeding channel 7 formed between the feeding bin 5 and the feeding roller 2. The feeding roller 2 prevents the plastic woven bag from running off during feeding, ensuring that the plastic woven bag smoothly enters the crushing bin 6 and is crushed by the crushing roller 3.

[0029] Preferably, the cross-section of the feeding bin 5 is oval. A plurality of solid material rings are uniformly installed on the feeding roller 2 along the axial direction. A groove 8 adapted to the solid material ring is provided on the inner peripheral wall of the feeding bin 5, and the groove 8 is located at the minor axis of the oval. The solid material ring is composed of a plurality of conical teeth 9 arranged along the circumferential direction.

[0030] For the solid material ring composed of conical teeth 9 on the feeding roller 2, when the feeding roller 2 rotates, the plastic woven bag advances with the feeding roller 2 to the groove 8, and the conical teeth 9 are inserted into the plastic woven bag to prevent the plastic woven bag from running off.

[0031] Preferably, the inner bottom of the feeding bin 5 is close to the outer peripheral surface of the feeding roller 2.

[0032] The inner bottom of the feeding bin 5 is sealed by the feeding roller 2, that is, the feeding channel 7 is sealed to prevent the plastic woven bag from flowing into the crushing bin from the other side of the feeding channel 7, causing material blockage. Embodiment

[0033] Based on the above embodiment, this embodiment shows that annular grooves 10 are provided on the feeding roller 2 between a plurality of solid material rings. The blades 11 of the crushing roller 3 are adapted to the annular grooves 10.

[0034] When the plastic woven bag reaches the entrance of the crushing bin 6 (the discharging port at the bottom of the feeding bin 5) with the feeding roller 2, the rotation trajectory of the blades 11 of the crushing roller 3 will pass through the annular grooves 10 on the feeding roller 2 to tear the plastic woven bag fixed by the feeding roller 2, achieving the crushing effect. Embodiment

[0035] Based on the above embodiment, this embodiment shows that a stripping tooth 12 adapted to the annular groove 10 is provided at the discharging port of the feeding bin 5.

[0036]

[0036] Some of the plastic woven bags are difficult to be removed from the feeding roller 2 or are too closely attached to the feeding roller 2. First, it is not easy for the blades 11 of the crushing roller 3 to catch them. Second, they keep rotating with the feeding roller 2, which affects the feeding function of the feeding roller 2 for other plastic woven bags. By using the stripping teeth 12, the end of the stripping teeth 12 will abut against the inner bottom of the annular groove 10 to separate the plastic woven bags on the feeding roller 2 and make the plastic woven bags move towards the feed inlet of the shredding bin 6, ensuring that the plastic woven bags are cut by the blades, that is, the crushing effect, and the feeding roller 2 can be stripped and cleaned.

[0037]

[0037] Preferably, a stripping bin 13 adapted to the stripping teeth 12 is further provided at the discharge port of the feeding bin 5.

[0038]

[0038] The outer bottom of the stripping teeth 12 should be lower than the outer track of the solid material ring and be located in the stripping bin 13 to ensure that the excess uncrushed plastic woven bags fall into the stripping bin 13 for collection and are re-fed into the feeding bin 5 for re-crushing.

[0039]

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
