Description

Technical Field

[0001] The utility model relates to the technical field of bag clamping devices, in particular to a bag clamping device used for a garbage bag breaking machine. Background Art

[0002] Garbage bag breaking machines are usually installed in smart trash bins. Plastic bags loaded with garbage fall into the bag breaking machine from the inlet. The bag breaking device tears the plastic bags to allow the garbage in the bags to flow out. The broken plastic bags are then clamped by the bag clamping device to separate them from the garbage in the bags, thereby sorting and recycling garbage. The bag clamping method and structure of the bag clamping device will have a great influence on the bag clamping effect and bag clamping rate.

[0003] The bag breaking machine previously invented by the inventor adopts two unpowered movable clamping plates in the bag clamping device, which utilizes downward pressure and gravity to clamp the plastic bag.

The bag clamping efficiency is low, and the downward impact force of the clamping plates is large, and the collision noise is loud, which is easy to cause damage to the bag breaking device below. For this reason, the inventor has improved the bag clamping device. Utility Model Content

[0040] like Figure 8 As shown, the baffle driving device is arranged on the outside of the bracket 11, including a motor 5 32, a rotating gear 34, a transmission gear 35, a chain 33 and a spring 36. The rotating gear 34 is respectively installed on one end of the baffle shaft 28 on both sides, and the transmission gear 35 is installed on the lower end of the left rotating gear 34. One end of the spring 36 is fixedly installed on the bottom of the bracket 11, and the other end is installed on the right rotating gear 34. The chain 33 connects each rotating gear 34 with the transmission gear 35 through the motor 5 32. The motor 5 42 drives the chain 33 to rotate the transmission gear 35 and the rotating gear 34, thereby rotating the baffle shaft 28, and then driving the saw blade baffle 25 and the cutting knife baffle 43 to move up and down.

[0041] A plc controller 23 is installed on the outside of the bracket 11. The plc controller 23 is electrically connected to motor 1 5, motor 2 15, motor 3 20, motor 4 30, motor 5 32 and motor 6 42 to control the start, stop and reversal of the motors.

[0042] The working principle of this embodiment is:

[0043] The device is installed in the trash bin. When the trash bin delivery port is opened, due to the different delivery strengths of the users, the trash bag slides through the guide teeth 24 at the bottom of the bracket 11 or collides with the guide teeth 24 in the middle of the bracket 11 by inertia and falls onto the saw blade baffle 25 and the cutter baffle 43. The PLC controller 23 starts the motor 3 20 after receiving the signal from the sensor on the delivery port. The motor 3 20 drives the ball screw 2 19 to rotate, so that the longitudinal guide device 18 moves downward along the longitudinal guide rail 17. After the square frame 3 falls and presses the trash bag to the travel limit, the PLC controller 23 controls the motor 3 20 to stop working.

[0044] Then the motor 15 starts to drive the driving wheel 6 to rotate, the driving wheel 6 drives the first driven wheel 7 meshing with it to rotate, the first driven wheel 7 in turn drives the second driven wheel 8 meshing with it to rotate, so that the first driven wheel 7 and the second driven wheel 8 rotate in opposite directions, driving the rotating shafts 2 on both sides to rotate in opposite directions, the racks 1 on the rotating shafts 2 on both sides rotate accordingly, the horn 4 on the rack 1 pierces the plastic bag through rotation, and rolls the plastic bag to wrap it around the rotating shaft 2, and then the PLC controller 23 controls the motor 15 to stop running;

[0045] At the same time, the motor 4 30 starts to drive the transmission shaft 29 and the circular saw blade 26 on the shaft to rotate in the baffle gap 27 to cut the garbage bag, the motor 6 42 starts to drive the cutter slider 41 to move back and forth on the reciprocating ball screw 40, and the cutter slider 41 drives the moving cutter 38 to move back and forth in the cutter gap 39 to cut the garbage bag. After the garbage bag is broken, the PLC controller 23 controls the motor 4 30 and the motor 6 42 to stop running;

[0046] Then the PLC controller 23 controls the motor three 20 to reverse, driving the ball screw two 19 to reverse so that the longitudinal guide slide 18 moves upward along the longitudinal guide rail 17 to the initial position and then stops. The garbage bag is lifted upward, and after the garbage in the bag flows out from the rupture, the motor two 15 starts the ball screw one 14 to rotate and drive the transverse guide slide 13 to move on the transverse guide rail 12 to the leftmost travel limit of the transverse guide rail 12 and stop. The PLC controller 23 controls the motor one 5 to reverse, and drives the rotating shafts 2 on both sides to reverse through the driving wheel 6, the first driven wheel 7 and the second driven wheel 8. The reverse rotation loosens the plastic bag and makes the garbage bag fall into the garbage bag recycling bin below; then the motor two 15 reverses the transverse guide slide 13 and moves it along the transverse guide rail 12 to the initial position;

[0047] At the same time, the motor 5 32 starts to drive the chain 33 to move downward, and a transmission gear 35 is arranged at the lower left of the left rotating gear 34. The rotating gears 34 on both sides and the baffle shaft 28 are driven by the chain 33 to move in opposite directions. The baffle shaft 28 drives the saw blade baffles 25 and the cutter baffle 43 on both sides to open downward at the same time, so that the garbage on the baffles on both sides falls into the garbage bin below. Since the transmission gear 35, the rotating gear 34 and the chain 33 have a certain friction resistance, the gravity of the baffles on both sides is not enough to support their own falling. With the help of the left pulling force of the spring 36, the right rotating gear 34 is pulled so that the baffles on both sides are completely opened downward.

[0048] After a fixed interval, the PLC controller 23 starts the motor 32 to pull upward, the chain 33 drives the transmission gear 35 and the rotating gear 34 to move the tensioning spring 36, and the baffle shaft 28 reverses to drive the saw blade baffle 25 and the cutting knife baffle 43 to rise back to the initial position. One operation cycle is completed and waits for the next start signal.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
