The two connecting plates in each pair are arranged one above the other, and the four connecting plates in the two pairs are arranged in a matrix.

[0026] Two movable blocks 12, which can move synchronously up and down and move closer or further apart, are installed between the two mounting plates. The two movable blocks 12 are arranged symmetrically, one on the left and one on the right. A drive mechanism is installed on the mounting bracket 5, and the drive mechanism is connected to the two movable blocks 12.

[0027] Specifically, the drive mechanism includes two sliders 9, a horizontal drive assembly, and a vertical drive assembly. The two sliders 9 are slidably mounted between two mounting plates and correspond one-to-one with two movable blocks 12. The two movable blocks 12 are located between the two sliders 9, and each movable block 12 is connected to the corresponding slider 9 through an elastic connector.

[0028] Specifically, the elastic connector includes slide rods 10. Two slide rods 10 are horizontally placed between the corresponding movable block 12 and slider 9.

[0034] The lateral drive assembly is driven by two movable blocks 12 so that the two movable blocks 12 move closer to each other and further away from each other during the up and down movement.

[0035] Specifically, the lateral drive assembly includes a push shaft 15. Each movable block 12 has a clearance groove on its front and rear sides, with the two clearance grooves on each movable block 12 facing away from each other, i.e., one facing forward and the other backward. A push shaft 15 is inserted into each clearance groove, and each push shaft 15 is in a limiting sliding engagement with the clearance groove. A second spring 14 is provided in each clearance groove along the sliding direction of the internal push shaft 15. One end of each second spring 14 is fixedly connected to the push shaft 15 in its respective clearance groove, and the other end is fixedly connected to its respective movable block 12.

[0036] Four transmission grooves, each corresponding to a push shaft 15, are formed on the adjacent end faces of the two fixed plates. These grooves are used to drive the push shaft 15 to translate horizontally as it moves up and down with the corresponding movable block 12. The push shaft 15 is inserted into the corresponding transmission groove and slides in a limiting engagement with the groove.

[0037] Specifically, the transmission groove includes a first vertical groove 18, a second vertical groove 19, a horizontal groove, and an inclined groove. The inclined groove is located at the top of the first vertical groove 18 and the second vertical groove 19 and connects the first vertical groove 18 and the second vertical groove 19.

The inner top wall of the ramp and the transmission ramp are both in contact with the push shaft 15 for transmission.

[0039] The inclined grooves located on the same fixed plate are arranged symmetrically in a figure-eight shape on the vertical plane.

[0040] An extension plate is fixedly installed on the left and right sides of the top plate, and a horizontally forward-facing rotating roller 2 is rotatably mounted on each of the two extension plates. The two rotating rollers 2 are symmetrically arranged with respect to the top plate and are equipped with rotational damping between themselves and their respective extension plates to ensure the smooth drop of the heat-sealed mugwort bag.

[0041] Non-woven fabric is wound onto both rotating rollers 2. Heat-sealing components 13 are fixedly installed on both movable blocks 12. In this embodiment, the working principle of the heat-sealing component 13 is the same as that of the heat-sealing device in the internal medicine filling device of a foot bath pack described in CN221050097U, and both belong to the prior art, so it will not be described in detail here.

[0042] Two nonwoven fabrics pass between the heating plates on the two movable blocks 12. The heat seal 13 in this embodiment includes two U-shaped heating plates that are close to each other to clamp the two nonwoven fabrics together and form a rectangular pocket between the two nonwoven fabrics for holding the mugwort leaves.

[0043] Two symmetrically arranged fixing plates, one on the left and one on the right, are fixedly installed on the vertical plate, located below the mounting frame 5. Each fixing plate is fixedly equipped with an electric push rod 16, with the telescopic shafts of the two electric push rods 16 horizontally opposed in the left-right direction. A cutting blade 17 for cutting non-woven fabric is fixedly installed at the near ends of the telescopic shafts of the two electric push rods 16, and the heat-sealed mugwort bag falls between the two cutting blades 17.

[0044] Working principle: In the initial state preparation, the non-woven fabric wound on the two rotating rollers 2 passes downward through the two movable blocks 12, the feed tube 4 is located in the middle area of ​​the two non-woven fabrics, the heat seal 13 is in a state of separation from each other, the two cutting blades 17 are in a state of separation from each other, the initial position of the push shaft 15 is located at the bottom of the first vertical groove 18, and the first spring 11 and the second spring 14 are both in a state of compression.

[0045] After the device is started, the two motors 6 start synchronously, driving the reciprocating screw 7 to rotate. Since the slider 9 is threadedly connected to the reciprocating screw 7 and limited by the limiting rod 8, the slider 9 moves smoothly upward along the limiting rod 8, and drives the movable block 12 to move upward synchronously through the slide rod 10 and the first spring 11. When the movable block 12 moves upward, the push shaft 15 slides upward along the first vertical groove 18 and then enters the inclined groove. The inner wall of the top of the inclined groove generates a horizontal inward squeezing force on the push shaft 15, causing the push shaft 15 to approach the non-woven fabric, thereby driving the two movable blocks 12 to approach each other, and the heat sealing component 13 approaches synchronously with the movable blocks 12. Because there is a rotational damping between the rotating roller 2 and the support plate 1, the non-woven fabric remains temporarily stationary. After the heat sealing components 13 are pressed together, they heat-seal the bottom and sides of the non-woven fabric, sealing the bottom and sides of the mugwort bag. At this time, the push shaft 15 enters the upper vertical groove of the second vertical groove 19 from the inclined groove, and the slider 9 moves up to the top of the reciprocating thread. Since the upper vertical groove is deeper than the lower vertical groove, the push shaft 15 slides out from the relief groove and into the upper vertical groove under the elastic force of the second spring 14, and at the same time abuts against the movable block 12 under the elastic force of the first spring 11.

[0046] After heat sealing, the heat sealing component 13 is closed, the feeding assembly is activated, and the mugwort in the material box 3 is precisely fed into the two non-woven fabric pockets formed after heat sealing through the feeding mechanism in the feeding pipe 4, completing the quantitative mugwort filling. After filling, the motor 6 continues to drive the reciprocating screw 7 to rotate, and the slider 9 drives the movable block 12 to move down. The push shaft 15 moves down from the upper vertical groove of the second vertical groove 19 to the transmission inclined surface. The transmission inclined surface exerts an inward squeezing force on the push shaft 15, and the push shaft 15 slides back to the clearance groove. Then, the push shaft 15 continues to slide down to the lower vertical groove and slides along the lower vertical groove to the connection with the horizontal groove; then, under the elastic force of the first spring 11, the push shaft 15 slides back to the bottom of the first vertical groove 18. During this process, the push shaft 15 drives the movable block 12 to move down first and then move horizontally; that is, the two movable blocks 12 move down synchronously first and then separate horizontally.

[0047] As the two movable blocks 12 move down synchronously, the mugwort sachet is also moved down synchronously and stops after moving down the length of the second vertical groove 19. During this process, the non-woven fabric releases the length of the second vertical groove 19. Then, another packaging cycle is performed, and the heat sealer 13 heat seals the top opening of the first mugwort sachet while heat-sealing the bottom and sides of the non-woven fabric. This process is based on the fact that the vertical length of the two distal ends of the heating plate of the heat sealer 13 is equal to the length of the second vertical groove 19.

[0048] During the release of the nonwoven fabric, it is released stably under the coordination of rotational damping, ensuring that the length of the heat-sealed mugwort bag meets the preset specifications.

[0049] The heat-sealed mugwort sachet moves downwards to the position of the cutting blade 17. The electric push rod 16 is activated, and its telescopic shaft pushes the two cutting blades 17 closer together, cutting the heat-sealed mugwort sachet from the subsequent non-woven fabric. The cut finished mugwort sachet falls and is collected. The electric push rod 16 resets, causing the cutting blades 17 to detach from the mugwort sachet, and the device returns to its initial state. It should be noted that this process can be controlled manually via control buttons or through a sensor and controller; this is existing technology and will not be elaborated upon here.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
