[0013] The dust-removing spiral feeding module 6 includes a mesh-shaped inner tube 601, an outer sleeve 602 is provided outside the mesh-shaped inner tube 601, a feed pipe 603 connected to the mesh-shaped inner tube 601 is provided above one end of the outer sleeve 602, and a discharge pipe 604 connected to the mesh-shaped inner tube 601 is provided below the other end of the outer sleeve 602; a spiral feeder 605 is provided in the mesh-shaped inner tube 601; the feed pipe 603 is connected to an inclined feed pipe 7 corresponding to the outlet of the feed hopper 1; a plurality of dust suction ports 606 are provided at the bottom of the outer sleeve 602, and the dust suction ports 606 are connected to a dust suction pipe 607 and a dust suction fan 608.

[0014] The feed hopper 1 includes a conical feed hopper body 101 , a rectangular box 102 is provided below the conical feed hopper body 101 , a rolling brush 103 is provided inside the rectangular box 102 , and a contraction port 104 is provided below the rectangular box 102 ; the electric gate 3 is located at the outlet of the conical feed hopper body 101 .

[0015] The crushing module 2 includes a first electric cylinder 201 located on the front side of the feed hopper 1, a first bracket 202 is provided at the output end of the first electric cylinder 201, and a first crushing knife 203 is provided at the end of the first bracket 202; it also includes a second electric cylinder 204 located on the left side of the feed hopper 1, a second bracket 205 is provided at the output end of the second electric cylinder 204, and a second crushing knife 206 is provided at the end of the second bracket 205.

[0016] The screw feeder is a traditional screw feeder.

[0017] The inclined feeding pipe is a hose.

[0018] Preferably, electric lifting rods are provided at both ends of the outer sleeve to adjust the left and right heights of the screen-shaped inner tube and the outer sleeve to facilitate discharge.

[0019] It also includes a controller for controlling the opening and closing of the electric gate according to the monitoring data of the weighing sensor to achieve control of the feeding amount.

[0020] Preferably, the rolling brush is connected to a driving motor located outside the rectangular box via a rolling shaft.

[0021] The working process of the utility model is as follows: a pile of ziplock bag raw material packages (granular PE materials are packaged into bags by packaging bags) are stacked next to the robot arm, the robot arm grabs the raw material package to the top of the feed inlet of the feed hopper, contacts the crushing module, cuts the bottom of the raw material package, and makes the raw material particles fall into the feed hopper, and then opens the electric gate according to the amount of raw materials required by the film blowing machine, and the weighing sensor monitors the feeding weight. When the set value is reached, the electric gate closes and the feeding stops. When the raw material particles fall into the rectangular box, they will come into contact with the rolling brush. The rotation of the rolling brush will act on the surface of the raw material particles, so that some dust or dust on the surface of the raw material particles is separated from the raw material particles. Then the dust and raw material particles fall into the screen-like inner tube through the inclined feeding pipe. Dust and other impurities pass through the screen-like inner tube and fall into the outer tube. Under the action of the spiral feeder, the raw material particles are pushed from the feed port to the discharge port and sent into the film blowing machine from the discharge pipe. In this process, dust and other impurities attached to the surface of the raw material particles will fall into the outer tube and be sucked out by the dust suction fan.

[0022] The crushing module operates as follows: The first electric cylinder drives the first crushing blade to cut the center horizontal line of the bottom of the raw material bag from right to left. The second electric cylinder drives the second crushing blade to cut the center longitudinal line of the bottom of the raw material bag from back to front, thus forming a cross-shaped opening at the bottom of the raw material bag. In this application, the horizontal direction of the raw material bag refers to the length, and the vertical direction refers to the width. Because traditional packaging bags are rectangular, the two crushing blades will not interfere with each other.
