detailed description

Referring to the accompanying drawings, the two-side-sealing flat bag packaging machine provided by the present invention will be described in detail in conjunction with an embodiment.

Example

Referring to Fig. 1-Fig. 4, the two-side sealing flat bag packaging machine of the present embodiment comprises an outer box body, a bag feeding device, a bag grabbing device, a feeding filling device, a sealing device and an output device, and the sealing device is installed outside In the middle position of the box body, the sealing device includes a front heat-sealing mechanism 2 and a rear heat-sealing mechanism 7, the bag feeding device is installed in front of the sealing device, the feed filling device is installed at the rear end of the sealing device, and the output The device is installed below the sealing device.

Two-side sealing flat bag packaging machine, the bag feeding device includes a plastic bag support frame, a tension wheel 6, and a support body 5, the plastic bag support frame is installed on the outer box, and the tension wheel and support body are arranged on the plastic bag Below the support frame; the bag-grabbing device is installed between the front heat-sealing mechanism and the rear heat-sealing mechanism, the bag-grabbing device includes a gear, a bag-grabbing rocker 3, a connecting rod, the gear is fixed on the outer box, and the A sliding groove and a bag grab handle 18 are arranged on the bag grabbing rocker, and one end of the connecting rod is installed at the center position of the gear, and the other end is installed in the sliding groove of the bag grabbing rocker; the rear heat sealing mechanism 7 of the sealing device With a cutter; the feeding filling device includes a feeding platform 11, a feeding device, a hinge opening device and a cam transmission device, and the feeding device includes a feeding push rod 1, a transmission gear and a transmission connecting rod, and the hinge The opening device 12 includes a hinge 13, a brace 14, a push rod 15, a connecting plate 16, and a connecting frame 17. The connecting plate and the connecting frame are fixedly connected to the outer box, and the brace and the connecting frame are connected by a hinge. One end of the ejector rod is connected to the support plate, and the other end is connected to the cam transmission device; the output device includes a motor 9, a conveyor belt 8 and a discharge port 10, and the discharge port is located in the middle position below the front heat-sealing mechanism and the rear heat-sealing mechanism

Two-side sealing flat bag packaging machine, when working, manually feed the beginning of the tubular packaging plastic bag 4 into the tensioning wheel, and the bag picking handle on the grab bag rocker pulls the beginning of the tubular packaging plastic bag in the tensioning wheel Into the heat-sealing mechanism, after reaching the position, the bag grabber is released, and returns to the next grabbing work. The bag grabber grabs and places the front end of the cylindrical packaging plastic bag at the hinge opening device, and then the cam drive drives the ejector rod to lift the support plate, rises and opens, and tightens the mouth of the cylindrical packaging plastic bag. After that, the feeding push rod swings back and forth to feed the material into the opened cylindrical packaging plastic bag, and then the front heat-sealing mechanism and the rear heat-sealing mechanism press down to seal the two ends of the cylindrical packaging plastic bag, and the rear heat-sealing mechanism The cutting knife cuts the sealed packaging bag from the cylindrical packaging plastic bag, and the sealed packaging bag is sent out from the discharge port by the conveyor belt, and the whole packaging process is completed. The movement of each mechanism is coordinated with each other and carried out synchronously, and is driven by a motor.
