Description

Horizontal sealing bag mechanism Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a horizontal sealing bag pulling mechanism. Background Technology

[0002] The equipment developed by our company is mainly used for seed packaging. After the seeds are poured into the packaging bags by the feeding machine, the packaging bags need to be sealed by the heat sealing machine. Our current automated operation equipment drives two plates to insert into the packaging bag, and then moves the plates outward to align the ends of the packaging bag before sealing it by the heat sealing machine. However, the plates need to be inserted into the bag to a certain depth, resulting in a large amount of empty space at the top of the packaging bag after sealing, which makes insufficient use of the packaging bag space. Therefore, we invented the horizontal sealing and pulling bag mechanism. Summary of the Invention

[0003] The purpose of this invention is to provide a horizontal sealing bag mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A horizontal sealing bag mechanism includes a frame, and a movable plate four and a movable plate one are arranged inside the frame. The movable plate four and the movable plate one can move closer to each other and further away from each other.

[0006] Both the fourth and first movable plates are equipped with horizontal sealing bag pullers at their tops. The horizontal sealing bag pullers are configured in four sets, with two sets of horizontal sealing bag pullers at the top of both the fourth and first movable plates. Furthermore, each pair of horizontal sealing bag pullers is arranged in a figure-eight shape.

[0007] The horizontal sealing bag puller includes a plate body one. Positioning pins one are fixedly installed on both sides of the top of the plate body one.

A tension spring 840 is connected between the spring pin 813 and the spring pin 823. When the four sets of horizontal sealing bag pullers 800 approach each other and contact the packaging bag, the second plate 830 moves outward due to the figure-eight arrangement and horizontally seals and pulls the packaging bag. The tension spring 840 has an elastic restoring effect on the second plate 830. The spring pin 813 and the spring pin 823 have a positioning effect on the tension spring 840. The positioning rod 811 has a positioning effect on the second plate 830.

[0028] The plate body 810 is fixedly installed on the top of the movable plate 700 or the movable plate 300;

[0029] The bottom of the four movable plates 700 and the one movable plate 300 are fixedly installed with closing plates 900. The two sets of closing plates 900 are close to each other and touch the side wall of the packaging bag, so that the top of the packaging bag closes inward.

[0030] Guide sleeves 110 are fixedly installed at both ends of the inner wall of the frame 100. Four sets of guide sleeves 110 are provided. Guide rods 200 are slidably connected to the inner wall of the guide sleeves 110. A movable plate 300 is fixedly installed at the right end of the guide rod 200, and a movable plate 400 is fixedly installed at the left end of the guide rod 200.

[0032] A drive mechanism is mounted on the frame 100. The drive mechanism includes a servo motor 510, which is fixedly mounted on the bottom of the frame 100. A clamp 520 is fixedly mounted on the output end of the servo motor 510. A rotating rod 530 is fixedly mounted on the clamp 520. A pull rod 540 is rotatably connected to the end of the rotating rod 530 away from the clamp 520. The pull rod 540 on the left side is rotatably connected to a second movable plate 400, and the pull rod 540 on the right side is rotatably connected to a third movable plate 60. 0; Servo motor 510 drives rotating rod 530 to rotate, rotating rod 530 drives pulling rod 540 to move, left pulling rod 540 drives moving plate 2 400 to move to the left, moving plate 2 400 drives moving plate 1 300 to move to the left through guide rod 200; right pulling rod 540 drives moving plate 3 600 to move to the right, moving plate 3 600 drives moving plate 4 700 to move to the right through top rod 610, servo motor 510 has a driving effect on moving plate 4 700 and moving plate 1 300.

[0033] A heat sealing machine 1000 is fixedly installed at the opposite ends of the movable plate 4 700 and the movable plate 1 300. The heat sealing machine 1000 is located between the horizontal sealing bag puller 800 and the closing plate 900. The heat sealing machine 1000 is used to heat and seal the packaging bag.

[0034] When the four sets of horizontal sealing bag pullers 800 approach each other and contact the packaging bag, the second plate 830 moves outward due to its figure-eight shape and horizontally seals and aligns the packaging bag. This horizontal sealing and alignment is done from the outside of the packaging bag, without needing to extend into the inside of the packaging bag. Furthermore, the contact area with the packaging bag is small, and the alignment process is fast, which increases the usable space of the packaging bag and improves the sealing efficiency.

[0035] The working principle of this utility model is as follows: When those skilled in the art connect the circuit components of this device to an external power supply and controller, the packaging bag is moved between the first moving plate 300 and the fourth moving plate 700, and the port of the packaging bag corresponds to the side of the horizontal sealing bag puller 800. The servo motor 510 is started to rotate, the servo motor 510 drives the rotating rod 530 to rotate, the rotating rod 530 drives the pull rod 540 to move, the left pull rod 540 drives the second moving plate 400 to move to the left, and the second moving plate 400 drives the first moving plate 300 to move to the left through the guide rod 200.

[0036] The right-side lever 540 drives the third movable plate 600 to move to the right, and the third movable plate 600 drives the fourth movable plate 700 to move to the right through the top rod 610;

[0037] At this moment, moving plate 1 300 and moving plate 4 700 slowly approach each other;

[0038] The closing plate 900 first contacts the side wall of the packaging bag, causing the top of the packaging bag to close inward;

[0039] Then the four sets of anti-slip strips 832 come into contact with the packaging bag;

[0040] As they continue to move closer together, the four sets of plates 2830 move outward, stretching the opening of the packaging bag outward and aligning it. After the four sets of plates 2830 move to the bottom, the two sets of heat sealers 1000 squeeze the opening of the packaging bag and start the heat sealer 1000 to seal the packaging bag.

[0041] The servo motor 510 is started to rotate, and the heat sealer 1000 is powered off; the second plate 830 is reset by the force of the tension spring 840, and the positioning rod 811 holds the second plate 830 in place, so that the second plate 830 continues to be set in a figure-eight shape.

[0042] The moving plate 300 and the moving plate 700 are moved away from each other by the force of the servo motor 510, and then the sealed packaging bag can be removed.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
