[0039] The crimping device is used to adhere the plug connector and the plug socket to corresponding positions respectively.

[0040] The feed hopper 81 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 83 is located at the outlet of the conical feed hopper body 101 .

[0041] The crushing module 82 includes a first electric cylinder 201 located on the front side of the feed hopper 81, 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 81, 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.

[0042] This application sets a crushing module at the feeding port of the feed hopper to cut the raw material package; and sets a manipulator on the side of the feed hopper to grab the self-sealing bag raw material package. Through the mutual cooperation between the above structures, it can replace the manual cutting and feeding method, which is easy to operate, greatly reduces the labor intensity of workers, and improves the feeding efficiency. At the same time, this application can accurately control the feeding amount by setting an electric gate and a weighing sensor; by setting a dust removal spiral feeding module, it can effectively remove the dust and dust on the surface of plastic particles such as PE, thereby improving product quality.

[0043] The screw feeder is a conventional screw feeder.

[0044] The inclined feeding pipe is a hose.

[0045] Preferably, electric lifting rods are provided at both ends of the outer sleeve, which can adjust the left and right heights of the screen-shaped inner tube and the outer sleeve to facilitate material discharge.

[0046] 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 the control of the feeding amount.

[0047] Preferably, the rolling brush is connected to a driving motor located outside the rectangular box via a rolling shaft.

[0048] The working process of this application is as follows: a pile of ziplock bag raw material packages are stacked next to the manipulator (granular PE materials are packaged into bags by packaging bags), the manipulator grabs the raw material package to the top of the feeding port 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 is closed to stop feeding. 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 part of the 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 attached to the surface of the raw material particles will fall into the outer tube and be sucked out by the dust suction fan.

[0049] The working process of the crushing module: the first electric cylinder works to drive the first crushing knife to cut the central horizontal line of the bottom of the raw material bag from right to left, and the second electric cylinder works to drive the second crushing knife to cut the central longitudinal line of the bottom of the raw material bag from back to front, so as to form a cross-shaped opening at the bottom of the raw material bag. The horizontal direction of the raw material bag in this application refers to the length direction, and the longitudinal direction refers to the width direction. Because traditional packaging bags are rectangular structures, the two crushing knives will not interfere with each other.

[0050] The method for using the self-sealing bag of the present application is as follows: after an object is placed in the bag and sealed with a sealing tape, the opening portion located in the area above the sealing tape can be folded over so that the iron protrusion of the plug connector can be inserted into the plug-in groove of the plug socket after being folded over and fixed by adsorption by a magnet, thereby preventing dust accumulation and bacterial growth in the opening portion; moreover, the area between adjacent plug connectors will form a handle area, which is convenient for users to take the self-sealing packaging bag filled with items.
