no. 1 approach

[0046] 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.

[0047] Moving knife mechanism

[0048] 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

[0107] 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.

[0108] 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.

[0109] hopper

[0110] 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.

[0111] feeding machine

[0112] The feeder 300' can b...

Abstract

The invention discloses a bag breaking machine which comprises a moving knife mechanism (100), a feeding port (340), a discharging port (350), a first fixed knife mechanism (220) and a second fixed knife mechanism (230). The feeding port and the discharging port are arranged on the upper portion and the lower portion of the moving knife mechanism respectively, and the first fixed knife mechanism and the second fixed knife mechanism are arranged on two sides of the feeding port along the moving direction of a moving knife (110) of the moving knife mechanism respectively. The two fixed knife mechanisms are arranged on two sides of the feeding port along the moving direction (namely the moving direction of materials) of the moving knife respectively. When the moving knife mechanism operates forwards and backwards, bag breaking can be finished through assisting of the two fixed knife mechanisms respectively. In addition, when the moving knife mechanism operates forwards, the first fixed knife mechanism is used for assisting the moving knife mechanism to break a bag, the second fixed knife mechanism can also be used for scraping entanglement on the moving knife, and vice versa.

Description

technical field [0001] The invention relates to the field of environmental protection material sorting, in particular to a bag breaking machine. 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, such as the pendulum bag breaking machine disclosed in CN201376690Y, include moving knives and static knives. The moving knives swing relative to the static knives and implement bag breaking through the staggered moving knives and static knives. However, the bag cannot be bro...
