Problems solved by technology

When in use, the rigid strips in the waste material are likely to be transverse to the moving direction of the moving knife, which may block the normal operation of the bag breaking machine
In addition, there may be small bags in the large bags in the garbage. The existing bag breaking machine can only break open the large bags, but cannot break open the small bags in the large bags, resulting in a low bag breaking rate.

no. 1 approach

[0047] The bag breaking machine according to this embodiment includes a moving knife mechanism 100, a static knife mechanism 200 and other functional mechanisms, as follows Figure 1 to Figure 5 Describe in detail.

[0048] Moving knife mechanism

[0049] The moving knife mechanism 100 of the present invention adopts a chain transmission, and includes a chain plate conveying device and a plurality of moving knives 110 . The movable knife 110 is installed on the chain plate conveying device, and moves with the chain transmission of the chain plate conveying device. Due to the chain transmission, the diameter of the sprocket is much smaller than that of the roller, and the torque arm is shorter. When driven by a motor with the same power, the power output to the sprocket is much larger than that output to the roller, and the resistance is stronger. powerful. Therefore, the tearing force transmitted to the movable knife 110 is also stronger. Therefore, the moving knife mechan...

no. 2 approach

[0108] The bag breaking machine according to this embodiment includes a feeder 300' and a moving knife mechanism 100. The end in the feeding direction is arranged opposite to the feeder 300' at intervals.

[0109] Wherein, both sides of the feeder 300' can be closed in various ways, for example, a hopper 200' can be provided to realize it. Refer below Figure 6 and Figure 7 Describe the preferred embodiment with hopper 200', feeder 300', moving knife mechanism 100 and other functional mechanisms.

[0110] hopper

[0111] The hopper 200' is used to store materials, and the materials are piled up along the height direction of the hopper 200'. The upper part, the lower part and one side of the hopper 200' are open, the upper part is open for feeding, the lower part is open for setting the feeder 300' and closing both sides of the feeder 300', one side of the hopper 200' is open for setting Moving knife mechanism 100.

[0112] feeding machine

[0113] The feeder 300' can b...

Abstract

The invention discloses a bag breaking machine and a bag breaking method, wherein the bag breaking machine comprises a movable cutter mechanism (100) and a fixed cutter mechanism (200), wherein the movable cutter mechanism (100) comprises a movable cutter (110), while the fixed cutter mechanism (200) comprises a fixed cutter (210); the fixed cutter (210) is arranged toward the movable cutter (110); and the density of the fixed cutter (210) is gradually increased along the movement direction of the movable cutter (110). Through the technical scheme, the density of the fixed cutter is increased so that the transverse space between the movable cutter and the fixed cutter can be gradually reduced on the one hand; therefore, the bags in various sizes can be torn gradually; and on the other hand, a carding function can be added extra.

Description

technical field [0001] The invention relates to the field of environmental protection material sorting, in particular to a bag breaking machine and a bag breaking method. Background technique [0002] Primary municipal solid waste not only contains a lot of plastic bags containing garbage, but in many cases there are also clusters or bundles of silk and strip materials, which cannot directly meet the requirements of the mechanized sorting process for uniformity and dispersed distribution. Therefore, it is necessary to break the plastic bag and spread the material evenly before the mechanized sorting process can be carried out. In other words, bag breaking is the first step in mechanized sorting. Existing bag breaking machines are usually drum-type, that is, a moving knife is set on the drum. When in use, the rigid strips in the waste material are likely to be transverse to the moving direction of the moving knife, which may block the normal operation of the bag breaking ma...
