Description

Garbage bag breaking machine

technical field

The utility model relates to a garbage processing device, in particular to a garbage bag breaking machine.

Background technique

Broken bags are of great significance to the treatment of urban bagged garbage. At present, there are three methods used in urban waste disposal: landfill, incineration and composting, and bagged waste must be broken before these three treatment methods. Bag breaking is an important link to ensure subsequent waste treatment, which is very important for reducing landfill. It is very important to increase the amount of incineration, improve the efficiency of incineration, and improve the efficiency of composting.

The current garbage bag breaking machine usually includes a power mechanism and a frame. A moving knife drum, a fixed knife seat and a fixed knife seat adjustment structure are installed on the frame. , the moving knife and the fixed knife are arranged alternately. The above-mentioned bag breaking machine hangs material on the knife head during the bag breaking process, which causes the material to be entangled on the moving knife roller, and the bag breaking effect is not good. In severe cases, it cannot work and cannot complete the bag breaking.

Utility model content

In order to solve the technical problems in the known technology, the utility model provides a garbage bag breaking machine which can avoid the cutter head hanging belt material from winding around the drum.

The technical scheme adopted by the utility model for solving the technical problems existing in the known technology is: a garbage bag breaking machine, including a power mechanism and a frame, on which a roller, a fixed knife seat and a fixed knife adjusting mechanism are installed, The fixed knife is installed on the fixed knife seat, and there are moving knives on the outer surface of the roller. Knife holder, the movable knife holder is fixedly connected with a movable knife radially extending out of the outer surface of the drum; a support sleeve is fixedly attached to the lower side of the movable knife holder, and an elastic The elastic part passes through the movable knife holder and connects with the inner surface of the roller; the support sleeve is rotatably connected with a roller connected with the outer peripheral surface of the cam, and the two ends of the roller are provided with auxiliary plates, so that A groove is arranged on the auxiliary plate, and the moving knife rest is slidably installed in the groove.

The utility model can also adopt the following technical measures:

The feature of the garbage bag breaking machine above is that the fixed knife adjustment mechanism includes a hydraulic cylinder, one end of the hydraulic cylinder is connected to the fixed knife, and the other end is installed on the frame.

The feature of the above garbage bag breaking machine is that the elastic component is a helical compression spring.

The utility model has the advantages and positive effects: the movable knife is telescopically installed on the drum, when the bag is broken, the movable knife protrudes outside the drum, and after the bag is broken, due to the joint action of the elastic part and the cam, the movable knife retracts to In the drum, since there is no cutter head on the moving knife drum, no material is hung on it. It ensures the normal operation of the bag breaking machine and improves the production efficiency of the bag breaking machine.

Detailed ways

In order to further understand the utility model content, characteristics and effects of the present utility model, the following examples are given hereby, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Fig. 1-Fig. 2, a kind of garbage bag breaker of the present utility model, comprises power mechanism, frame 1, and roller 4, fixed knife seat and fixed knife adjusting mechanism are installed on frame 1, and fixed knife seat is installed There are fixed knives 5, and there are moving knives 2 on the outer circular surface of the drum 4. The moving knives 2 and the fixed knives 5 are arranged alternately, and also include a cam 3 coaxial with the drum 4, fixedly installed, and located inside it; A movable knife holder 10 is provided, and a movable knife 5 extending radially out of the cylinder outer surface is fixedly connected to the movable knife holder 10, and there is a gap between the movable knife 5 and the cylinder 4; the movable knife A supporting sleeve 8 is fixedly connected to the lower side of the frame 10, and an elastic component is installed in the supporting sleeve 8, and the elastic component passes through the moving knife holder 10 and connects with the inner surface of the drum; the supporting sleeve 8 is rotatably connected There is a roller 9 in contact with the outer peripheral surface of the cam 3 . Both ends of the drum 4 are provided with auxiliary plates 11, and grooves are arranged on the auxiliary plates 11, and the movable knife rest 10 is slidably installed in the grooves.

The fixed knife adjusting mechanism includes a hydraulic cylinder 6 , one end of which is connected to the fixed knife 5 , and the other end is installed on the frame 1 . The elastic component can be a helical compression spring 7 or other elastic components such as rubber elastic sleeve components.

Working principle of the utility model:

The drum drive can be a hydraulic motor or a motor reducer. The driving device directly drives the drum. There are several moving knives on the drum for breaking bags, and several fixed knives are installed on the frame. The bag-breaking moving knife on the drum moves at a certain speed and moves relative to the fixed knife installed on the frame. The bag containing the garbage is brought between the moving knife and the fixed knife by the passive knife to be torn. The movable knife on the drum rotates to the non-working range, and the bag breaking movable knife is retracted into the drum under the drive of the spring and the fixed cam, which ensures that the bag breaking machine can break the bag and not entangle the material. The shafts at both ends of the drum are supported on the two bearing seats of the box fixed to the frame, which ensures the overall rigidity. The fixed knife is installed on the shaft, and the fixed knife shaft is installed on the bearing seat and installed on the upper end of the box. The fixed knife is connected with the hydraulic cylinder to ensure a certain distance between the fixed knife and the moving knife to complete the function of breaking bags.
