As shown in fig. 5, the pulley assembly 7 includes a vertical plate 71, a guide rod 73, a mounting plate 72, a sliding plate 74, a driving pulley 75, a driven pulley 76, and a pulley motor 78. The number of the vertical plates 71 is two, and the two vertical plates 71 are oppositely arranged and mounted at the top end of the frame of the housing 1. Specifically, two standing plates 71 are respectively located right above the accommodating box 31 and the collecting bucket 5. The mounting plate 72 and the guide rod 73 are respectively clamped between the two vertical plates 71, the driving wheel 75 and the driven wheel 76 are respectively rotatably mounted at two ends of the mounting plate 72 along the length direction, the belt wheel motor 78 is mounted on the mounting plate 72, an output shaft of the belt wheel assembly 78 is in transmission connection with the driving wheel 75, and the synchronous belt 77 is wound on the driving wheel 75 and the driven wheel 76. The slide plate 74 is connected to the timing belt 77 and slidably fitted over the guide rod 73, and the lift rod 41 is mounted on the slide plate 74.

In this embodiment, the pulley motor 78 drives the driving pulley 75 to rotate in a forward direction, so that the conveyor belt 21 drives the sliding plate 74 to move along the guide rod 73 toward the collecting barrel 5, thereby moving the clamping plate assembly 4 holding the empty garbage bag above the collecting barrel 5. When the empty trash bag is released by the clamp 44, the pulley assembly 7 drives the driving pulley 75 to rotate in the opposite direction, so that the conveyor belt 21 drives the sliding plate 74 to move along the guide rod 73 in the direction toward the accommodating box 31, and the clamp assembly 4 moves above the accommodating box 31. The position switching of the clamping plate assembly 4 between the accommodating box 31 and the collecting barrel 5 is realized through a belt transmission mode, so that the transmission of the clamping plate assembly 4 is stable. Meanwhile, the belt wheel assembly 7 is simple in structure, low in cost and convenient to use and maintain.

After the automatic bag breaking machine completes bag breaking, part of the garbage may remain at the corner position of the garbage bag or adhere to the inner wall of the garbage bag, which is not beneficial to complete dumping and recycling of the garbage. To solve this problem, as shown in fig. 5, the cleat assembly 4 further includes a first driving member 42 and a second driving member 43, and the first driving member 42 is drivingly connected with at least two cleats 44 to drive the cleats 44 to approach or move away from each other. The second driving member 43 is disposed on the lifting rod 41, and an output shaft of the second driving member 43 is rotatably connected to the first driving member 42 to drive the first driving member 42 and the two clamping plates 44 to rotate.

Specifically, when the bag is broken, the first driving member 42 continues to drive the at least two clamping plates 44 toward each other to clamp the empty bag. Second driving piece 43 can drive first driving piece 42, splint 44 and empty disposal bag rotatory to through the effect of the rotation of empty disposal bag and the centrifugal force that produces, with remaining rubbish in the empty disposal bag and the separation of empty disposal bag, guaranteed disposal bag and rubbish complete separation, improved the recycle ratio of rubbish.

Preferably, the second driving member 43 can drive the first driving member 42, the clamping plate 44 and the empty garbage bags to rotate in the forward direction and the reverse direction alternately. The garbage separating device has the advantages that the garbage separating device can alternatively rotate in the forward direction and the reverse direction, residual garbage at each corner position in the empty garbage can be separated from garbage points, the garbage separating effect is further improved, and the garbage recycling rate is improved.

The clamp assembly 4 of this embodiment also includes a first sensor disposed on the clamp plate 44 for measuring the weight of an empty trash bag separated from the trash. When the weight measured by the first sensor is greater than or equal to the first preset value, the first driving member 42 can be driven to rotate, so that the clamping plate 44 and the empty garbage bag rotate synchronously.

Specifically, the first driving member 42 may be a conventional driving structure such as a motor, a hydraulic cylinder or an air cylinder, and the second driving member 43 may be a rotary motor. The first sensor is a weight sensor. The first preset value can be set autonomously by a person skilled in the art according to actual conditions. For example, the first set value may be 0.05kg, 0.1kg, 0.15kg, or the like.

The number of the clamping plates 44 of the present embodiment is two, and the two clamping plates 44 are oppositely arranged and have three working positions. Of course, the number of decks 44 may also be three, four, or more than four. The clamps 44 are in the first operative position when the clamps 44 are in the horizontal orientation before the bag is undamped. When the lifting rod 41 drives the clamping plates 44 to extend into the accommodating box 31, the two clamping plates 44 rotate downwards until the garbage bag is clamped, and at the moment, the clamping plates 44 are located at the second working position. When the bag is broken and the waste falls, the two jaws 44 continue to move towards each other to grip an empty bag, with the jaws 44 now in the third operating position.

The clamping plate 44 is an isosceles triangular plate, the bottom outer edge side of the clamping plate 44 is provided with a plurality of conical cylinders, and a plurality of conical bodies form clamping teeth 441. When splint 44 centre gripping disposal bag, press from both sides tooth 441 can pierce through the disposal bag to improve the clamping strength of splint 44 and disposal bag, avoid the disposal bag to fall into simultaneously with rubbish and hold case 31.

As shown in fig. 3, the automatic bag breaker further comprises a second sensor located at the bottom of the collecting bucket 5 for measuring the weight of the collecting bucket 5. The second sensor of this embodiment is a weight sensor, which can monitor the weight of the collecting bucket 5 in real time. When the second sensor detects that the weight of the collecting bucket 5 reaches a certain value, an electric signal can be sent to the control unit, so that the control unit sends out a light prompt or a sound prompt for replacing the collecting bucket 5.

It should be noted that, a person skilled in the art can set the replacement weight of the collecting bucket 5 autonomously according to actual conditions, and the setting is not limited in detail here. For example, the replacement weight of the collecting bucket 5 may be 5kg, 7kg, 10kg, or the like.

Preferably, a guide channel 6 is arranged right above the collecting barrel 5, the guide channel 6 is arranged on the frame of the shell 1, and the empty garbage bag clamped by the clamping plate assembly 4 can fall into the collecting barrel 5 through the guide channel 6, so that the empty garbage bag is prevented from falling into the outer part of the collecting barrel 5.
