[0033] Further explanation: The conveying packaging film mechanism 6 includes a servo motor and a plurality of conveying rollers installed on the frame 1. The plurality of conveying rollers are distributed up and down and are in contact with the cylindrical film. The servo motor drives the conveying rollers to rotate to convey the cylindrical film.

[0034] The sealing mechanism includes a movable moving frame 14 installed on the frame 1. A slide rail and two first driving cylinders 2 are fixed on the frame 1. The moving frame 14 is slidably installed on the slide rail, and the output end of the first driving cylinder 2 is fixedly connected to the moving frame 14.

[0035] Upper heat sealing plates 7 and lower heat sealing plates 8 distributed up and down are installed on both the frame 1 and the moving frame 14. The two upper heat sealing plates 7 on the frame 1 and the moving frame 14 are arranged oppositely, and the two lower heat sealing plates 8 on the frame 1 and the moving frame 14 are arranged oppositely. The two upper heat sealing plates 7 are in contact with each other and the two lower heat sealing plates 8 are in contact with each other, so as to heat-seal the cylindrical film.

[0036] The cutting mechanism includes two second driving cylinders 5 installed on the moving frame 14. A cutter 13 is fixed to the output end of the second driving cylinder 5, and the cutter 13 is located between the upper heat-sealing plate 7 and the lower heat-sealing plate 8.

[0037] The bag suction mechanism and the bag clamping mechanism 16. The bag clamping mechanism 16 includes a sixth driving cylinder installed on the machine frame 1. A pneumatic claw is fixed to the output end of the sixth driving cylinder, and the pneumatic claw is used to clamp both ends of the lower end of the cut tubular film.

[0038] The bag suction mechanism and the bag clamping mechanism 16 cooperate to pull open the upper end of the cut tubular film to make it open. The bag suction mechanism is a slider slidably installed on the machine frame 1 and the moving frame 14. The slider is located between the upper heat-sealing plate 7 and the lower heat-sealing plate 8, and the slider is located below the cutter 13. A plurality of negative pressure suction heads 12 are installed on the slider. A third driving cylinder 15 is fixedly installed on the machine frame 1 and the moving frame 14, and the output end of the third driving cylinder 15 is fixedly connected to the slider.

[0039] The hopper guiding mechanism extends into the opened tubular film for loading. After loading is completed, the hopper guiding mechanism resets. The hopper guiding mechanism includes a fourth driving cylinder 3 fixed to the machine frame 1. A material guiding hopper 4 is fixed to the output end of the fourth driving cylinder 3, and the material guiding hopper 4 is disposed opposite to the cut tubular film.

[0040] It further includes a bag pressing mechanism. The bag pressing mechanism includes a fifth driving cylinder 9 fixed to the bottoms of the machine frame 1 and the moving frame 14. An arc-shaped pressing block 10 is fixed to the output end of the fifth driving cylinder 9. A support block 11 used in cooperation with the arc-shaped pressing block 10 is fixed on the moving frame 14. The bag pressing mechanism can position the tubular film to ensure the stability during loading of the tubular film. Among them, the arc-shaped pressing block 10 and the negative pressure suction heads 12 are on the same horizontal plane, and the arc-shaped pressing block 10 and the support block 11 are located between the negative pressure suction heads 12. The arc-shaped pressing block 10 and the support block 11 are used to clamp the tubular film opened by the bag suction mechanism.

[0041] The sealing mechanism works to seal the upper end of the cut tubular film and release the sealed and loaded tubular film for discharging.

[0042] The specific sealing steps are as follows:

[0043] The tubular film reaches a specified length through the conveying and packaging film mechanism 6 and is located between the sealing mechanisms. The first driving cylinder 2 drives the moving frame 14, the upper heat-sealing plate 7, and the lower heat-sealing plate 8 to move. At this time, the upper heat-sealing plate 7 is powered on and the lower heat-sealing plate 8 is powered off. Finally, the upper heat-sealing plate 7 and the lower heat-sealing plate 8 on the moving frame 14 abut against the upper heat-sealing plate 7 and the lower heat-sealing plate 8 on the machine frame 1, and the upper heat-sealing plate 7 cooperates to perform heat-sealing treatment on the tubular film.

[0044] At this time, the second driving cylinder 5 works to drive the cutter 13 to move. The clamped tubular film can be cut by the cutter 13. At the same time, the negative pressure suction head 12 abuts against the tubular film, and the output end of the sixth driving cylinder drives the gripper to move, and the gripper is used to clamp both ends of the cut tubular film; the third driving cylinder 15 drives the slider and the negative pressure suction head 12 to move, and at the same time, the first driving cylinder 2 resets, so that the upper end of the cut tubular film can be opened, and the opened tubular film abuts against the support block 11. The fifth driving cylinder 9 drives the arc-shaped pressing block 10 to move downward, and the tubular film can be clamped and positioned.

[0045] At this time, the fourth driving cylinder 3 drives the feeding hopper 4 to move downward and extend into the opened tubular film, and the material is conveyed into the tubular film through the feeding hopper 4; then the first driving cylinder 2 drives the moving frame 14, the upper heat-sealing plate 7 and the lower heat-sealing plate 8 to move again. At this time, the upper heat-sealing plate 7 is powered off and the lower heat-sealing plate 8 is powered on. The tubular film can be heat-sealed through the lower heat-sealing plate 8, so as to realize the packaging of the material. Then, the bag clamping mechanism 16, the fifth driving cylinder 9, etc. are reset. At this time, the packaged tubular film (packaging bag) is no longer clamped, and the blanking is realized.

[0046] Then, the sealing and packaging of the next tubular film are carried out.

[0047] An active plate capable of supporting can be installed at the bottom of the tubular film to support the tubular film during loading.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
