Description

Technical Field

[0001] The utility model relates to the technical field of waste collection devices, in particular to a waste collection device for removing rubber burrs. Background Art

[0002] After rubber products are manufactured and formed, they will have certain burrs. On the one hand, the burr treatment of rubber products has high requirements for the product appearance, and on the other hand, it is also inevitably related to the product price. Generally, the burr treatment process of rubber products also has certain production costs for manufacturers. Therefore, under the premise of ensuring product quality in the burr treatment link, manufacturers pay more attention to the burr treatment efficiency of rubber products. The manufacturing and molding of some rubber products will be accompanied by large-volume sheet or block burrs. This burr has irregular shapes. After being collected as waste and stacked together, it occupies a lot of space, resulting in a waste of site resources. At the same time, large-volume rubber burrs are more likely to clump after being concentrated, affecting secondary utilization.

[0003] A Chinese patent with publication number CN214026731U discloses a waste collection device for removing rubber burrs. The device passes a portion of the waste that is too small through a filter screen into a first storage box. At this time, a blower is turned on to blow the waste that is too large into a second shell. Then, a suction machine is turned on to put the waste in the second shell back into the first shell for secondary screening. After a certain number of cycles, the suction machine is turned off to put the waste that is too large into the second storage box.

[0004] In the above patent, there is a problem that it is difficult to collect and process large-volume sheet or block rubber burrs; therefore, it does not meet the existing needs, and a waste collection device for removing rubber burrs is proposed. Utility Model Content

A rotating disk that can rotate as a whole is arranged inside the cutting chamber. A fixed disk is arranged below the cutting chamber. A first cutting knife is arranged below the rotating disk. A second cutting knife is arranged above the fixed disk. The first cutting knife and the second cutting knife are staggeredly distributed inside the cutting chamber without interfering with each other. When the rubber burrs are located inside the cutting chamber, a motor drives the rotating disk to rotate. The cutting knife cuts the large-volume rubber burrs into small-volume burrs. The small-volume burrs fall from the through holes on the surface of the fixed disk into the collecting chamber below. The problems in the prior art can be solved.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] To solve the problem of difficult collection and processing of large-volume sheet or block rubber burrs, please refer to Figure 1-4 The utility model provides an embodiment: a waste collection device for removing rubber burrs, comprising an upper cover 1 and a collection chamber 3, and also comprising a cutting chamber 2, the cutting chamber 2 is installed below the upper cover 1, the inner surface of the cutting chamber 2 is provided with a track 201, the upper part of the upper cover 1 is provided with a feed port 101, a cold air inlet 601 and a motor 401, the interior of the cutting chamber 2 is provided with a rotating disk 4 that can rotate as a whole, the lower part of the rotating disk 4 is provided with a first cutting knife 402, the lower part of the rotating disk 4 is provided with a cold air chamber 6, the collection chamber 3 is installed below the cutting chamber 2, the upper part of the collection chamber 3 is provided with a fixed disk 5, the upper part of the fixed disk 5 is provided with a second cutting knife 501, and the surface of the fixed disk 5 is provided with a plurality of circular discharge ports 502.

[0025] The upper cover 1 is connected to the cutting chamber 2 by a hinge 102. When the cutting chamber 2 needs to be cleaned, the upper cover 1 can be opened to facilitate cleaning operations. A cold air duct is arranged inside the upper cover 1, one end of the cold air duct is connected to the cold air inlet 601, and the other end of the cold air duct is connected to the cold air chamber 6. The outer surface of the cold air chamber 6 is provided with a grille, and the surface of the cold air chamber 6 is provided with a plurality of through holes. When the cutting chamber 2 starts cutting, a large amount of heat will be generated between the blade and the rubber burrs. The rubber burrs may melt due to overheating, resulting in the burrs sticking to each other. At this time, cold air can be introduced from the outside, and the cold air enters the cold air chamber 6 from the cold air inlet 601, and overflows and diffuses to the entire cutting chamber 2, thereby reducing the temperature and further improving the efficiency of the entire cutting process.

[0026] The fixed disk 5 is fixed to the collecting chamber 3 by a buckle, the second cutting knife 501 is elliptical, and cutting blades are installed at both ends of the long axis of the second cutting knife 501, and the second cutting knife 501 is connected to the fixed disk 5 by screws; the rotating disk 4 is composed of two circular rings of different sizes, and the circular rings are connected by reinforcing ribs 403. The rotating disk 4 is installed inside the track 201, and a first gear 404 and a second gear 405 are arranged above the rotating disk 4. The first gear 404 is meshed with the second gear 405, and the first gear 404 is connected to the rotating disk 4 by screws; the first cutting knife 402 is elliptical, and cutting blades are installed at both ends of the long axis of the first cutting knife 402. The first cutting knife 402 is higher than the second cutting knife 501, and the first cutting knife 402 is arranged in a circular manner into two layers inside and outside, and the second cutting knife 501 is also arranged in a circular manner and is set in the middle of the two layers of first cutting knives 402.

[0027] The motor 401 extends a rotating shaft downward, and the lower end of the rotating shaft is connected to the second gear 405 by a flat key. When the rubber burr is located inside the cutting chamber 2, the motor 401 is started to rotate the rotating shaft and then drives the second gear 405 to rotate. The second gear 405 then drives the first gear 404 to rotate. The first gear 404 is fixed on the top of the rotating disk 4, forcing the rotating disk 4 to rotate along the track 201, and the fixed disk 5 is stationary. At this time, the first cutting knife 402 makes a circular motion, and the second cutting knife 501 is fixed. The upper and lower cutting knives cooperate to cut the large volume of rubber burr into small volume burr. The small volume of burr falls from the through hole on the surface of the fixed disk 5 to the collection chamber 3 below. After cutting, the burr becomes smaller and easier to store, which further improves the space utilization.

[0028] Working principle: the rubber burrs are fed into the cutting chamber 2 from the feed port 101, a rotating disk 4 which can rotate as a whole is arranged inside the cutting chamber 2, a fixed disk 5 is arranged below the cutting chamber 2, a first cutting knife 402 is arranged below the rotating disk 4, and a second cutting knife 501 is arranged above the fixed disk 5. The first cutting knife 402 and the second cutting knife 501 are staggeredly distributed inside the cutting chamber 2 and do not interfere with each other. When the rubber burrs are located inside the cutting chamber 2, the motor 401 drives the rotating disk 4 to rotate, and the cutting knife cuts the large volume of rubber burrs into small volume burrs, and the small volume of burrs falls from the discharge port 502 on the surface of the fixed disk 5 to the collecting chamber 3 below.
