[0007] The canvas bag is picked up by a pneumatic needle suction cup and the handle strap is pulled out from the bottom of the canvas bag by a telescopic lever.

[0008] In one embodiment, the pneumatic needle suction cups are provided with two groups, and the two groups of the pneumatic needle suction cups are arranged along the conveying direction of the conveyor line, so as to grab the bag opening.

[0009] In one embodiment, the two groups of pneumatic acupuncture suction cups are lifted and lowered by a first cylinder, and the first cylinder is fixed to the bottom of the top beam of the bracket through a component mounting frame.

[0010] In one of the embodiments, a track is provided above the top crossbeam of the bracket, and the sliding frame is slidably installed on the track. A motor fixed to the bracket is provided at one end of the track. The output end of the motor is connected to the sliding frame through a transmission belt, and the motor drives the sliding frame to move back and forth along the direction of the track through the transmission belt, which can drive the gear lever to achieve: pulling the handle strap at the mouth of the grabbed canvas bag out of the bottom of the canvas bag.

[0011] In one embodiment, the sliding frame is N-shaped, and its top is slidably installed on the top crossbeam of the bracket. The second cylinder is provided with two groups, and the two groups of the second cylinders are respectively fixedly installed at the two ends of the bottom of the sliding frame, and the two groups of the second cylinders are arranged along the conveying direction of the conveyor line, and the gear rods at the output ends of the two groups of the second cylinders are arranged opposite to each other.

[0012] Compared with the prior art, the belt turning mechanism of the utility model has the following advantages:

[0013] The bag opening of the canvas bag is grabbed by lifting and lowering the pneumatic needle suction cup, and at the same time the gear rod is extended into the lower end of the bag opening, and the driving member drives it to turn out the handle strap at the bottom of the bag, so as to smooth the bag handle strap and solve the problem that the handle strap of the canvas bag is easily pressed during production and transportation.
