[0002] In the processing and production of traditional Chinese medicine (TCM) materials, quantitative batch packaging of the herbs is necessary. Currently, the industry mostly uses vertical packaging machines to package the pre-quantified herbs. Existing vertical packaging machines typically employ independent and complex drive and transmission systems for their vertical and horizontal sealing mechanisms. This usually requires multiple cylinders or servo motors for each mechanism, supplemented by connecting rods, cams, sliders, and other mechanical components to achieve actions such as opening, closing, pressing, cutting, and resetting of the heat-sealing head. This structure not only makes the overall machine layout bulky and increases equipment costs but also leads to cumbersome assembly and debugging processes. Furthermore, the multiple drive components increase the probability of equipment failure, making troubleshooting and maintenance more inconvenient.

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 5 As shown in the figure, a specific embodiment of the present invention discloses a packaging device for traditional Chinese medicine materials, including a housing 100, a film feeding structure 200, a forming device 300, a pulling structure 400, a vertical sealing mechanism 500, and a horizontal sealing mechanism 600 mounted on the housing 100; the film feeding structure 200 is used to release the packaging film; the forming device 300 is used to form the passing film into a cylindrical shape and to receive and guide the material; the vertical sealing mechanism 500 is used to seal the side of the packaging bag; the pulling structure 400 is used to pull the packaging bag downwards; the horizontal sealing mechanism 600 is used to seal the packaging bag. After the side of the packaging bag is sealed, the top and bottom of the packaging bag are sealed and then cut. The horizontal sealing mechanism 600 includes a first pressing structure 610, a second pressing structure 620, and a first cylinder 630. The first cylinder 630 is used to drive the first pressing structure 610 to move towards the second pressing structure 620. The first pressing structure 610 is provided with a cutter 614 for cutting. The movement of the second pressing structure 620 towards the first pressing structure 610 and the sealing action of the vertical sealing mechanism 500 are both driven by the second cylinder 700. The aforementioned Chinese herbal medicine packaging equipment only uses a first cylinder and a second cylinder as driving components. By utilizing the operation and transmission of each structure, it completes multiple actions such as vertical sealing, horizontal sealing, and cutting. The overall structure is simple and compact, making it easy to assemble and debug. It can also effectively reduce the use of driving components, reduce equipment and operating costs, reduce failure rate, and facilitate maintenance. The pull structure has an outer top frame below it, which is used to push the side-sealed packaging bag outward so that the packaging bag is adjusted to the pressing part of the horizontal sealing mechanism. It should be noted that the outer top frame, film feeding structure, forming device and pull structure are all common structural components in packaging equipment, which can be purchased and used on the market, and will not be described in detail. Furthermore, it also includes an air compressor, which provides the necessary operating power for the first and second cylinders. Air compressors and cylinders are common combinations and can be purchased and used on the market, so details will not be elaborated here.

[0018] Furthermore, such as Figures 4 to 7 As shown, the vertical sealing mechanism 500 includes a first pusher 510 and two opposing clamping plates 520. The clamping plates are movably installed inside the housing. The clamping plates 520 have a protruding plate 521 that penetrates the front wall of the housing 100. A third heat-pressing strip 530 is installed on the protruding plate 521. The two third heat-pressing strips extend vertically, and a first clamping channel for sealing the side of the packaging bag is formed between the two third heat-pressing strips. The first clamping channel is located above the pulling structure. The first pusher 510 and the clamping plates 520 are driven together. When the second cylinder 700 drives the second pressing structure 620 to move toward the first pressing structure 610, it simultaneously drives the first pusher 510 to move, so that the two clamping plates 520 move toward each other. This structural design can convert the opening and closing action of the clamping plates into the lateral movement action of the first pusher through the cooperation between the first pusher and the clamping plates, so that it follows the movement direction of the second pressing structure. In other words, the second cylinder can be used to complete the synchronous drive of the two, so as to achieve the effect of one driving component driving multiple components.

[0019] Furthermore, the vertical sealing mechanism 500 includes a first support structure 540 and a second support structure 550; the first support structure 540 includes a first bracket 541, on which a first support rod 542 is mounted; the second support structure 550 includes a second bracket 551, on which a second support rod 552 is mounted; both the first and second brackets are mounted on the chassis, with the first bracket located above the second bracket; the clamping plate 520 has multiple first through holes 522 corresponding to the first and second support rods, and a first linear bearing is installed on the outside of the first through hole, and the clamping plate is slidably mounted on the first and second support rods through the first linear bearing; the provided first and second support structures provide the necessary support for the two clamping plates, enabling them to be mounted on the chassis and to move towards each other; A first spring 543 is fitted onto the first support rod 542, and a second spring 553 is fitted onto the second support rod 552. The first spring 543 and the second spring 553 are sandwiched between two clamping plates 520. A second cylinder 700 is mounted on a second bracket 551, and a third push plate 710 is mounted on the piston rod end of the second cylinder 700. The second pressing structure 620 and the first push frame 510 are both mounted on the third push plate 710. The first push frame 510 is engaged on the outside of the two clamping plates 520. The first push frame, which moves forward, drives the two clamping plates to move towards each other. The first spring and the second spring provide an outward unfolding force to the clamping plates, so that the clamping plates can return to the unfolded state after being released from the force of the first push frame, allowing the third heat-pressing strip to detach from the packaging bag. The second pressing mechanism and the first push frame are both mounted on the third push plate and driven by the second cylinder. The simple structure is used to achieve the required synchronous movement effect, simplifying the overall structure and facilitating processing, production, assembly, and debugging.

[0020] Furthermore, a first protrusion 523 is fixedly provided in the middle of the outer wall of the clamping plate 520. The outer wall of the first protrusion has a sloping structure, tilting inward towards the second cylinder. The first pusher 510 has a U-shaped structure, with rollers 511 rotatably mounted at both ends of the opening. The outer wall of the rollers 511 abuts against the sloping surface of the first protrusion 523. Through the cooperation of the rollers and the sloping surface, when the first pusher pushes forward, the two clamping plates can move towards each other, thereby bringing the two third hot pressing strips together to complete the sealing of the side of the packaging bag. The simple structure of rollers and sloping surfaces changes the direction of force, and while moving forward in accordance with the second cylinder pushing the second pressing structure, the two third hot pressing strips move together and press. Moreover, this action is a flat opening and closing action, not a traditional swinging opening and closing action, which can improve the molding quality and facilitate better shape control. Furthermore, the front wall of the chassis is provided with a first window for the protruding plate to extend. The two sides of the first window also serve as the parts that limit the reverse unfolding and movement of the clamping plates, limiting the distance between the two clamping plates to be maintained at a preset position, so as to facilitate the cooperation with the first pusher and perform a rapid pressing action through the pushing action of the first pusher. Furthermore, the first and second support rods are respectively positioned above and below the first protrusion, so that the first pusher and the first protrusion are positioned between the first and second support rods, so that the whole is in a relatively balanced state, so that the force can be transmitted and distributed.

[0021] Furthermore, such as Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, the second pressing structure 620 includes a second push plate 621 and a second hot pressing strip 622. The second push plate 621 and the third push plate 710 are connected by a first push rod 720. The second hot pressing strip 622 is installed on the wall surface of the second push plate 621 away from the first push rod. The second pressing structure moves in and out of the front wall surface of the chassis through an opening. The first pressing structure 610 includes a first push plate 611 and a first hot pressing strip 612. The first push plate 611 is driven by a first cylinder 630. The first cylinder 630 is mounted on a third bracket 640. On the outer side of the front wall of the chassis, the first heat-sealing strip 612 is installed on the wall surface of the first push plate 611 away from the first cylinder. The first heat-sealing strip 612 and the second heat-sealing strip 622 are positioned correspondingly to form a horizontal sealing part. The first cylinder and the second cylinder respectively drive the first heat-sealing strip and the second heat-sealing strip to move towards each other and close together to press and seal the packaging bag in this part. The first heat-sealing strip and the second heat-sealing strip operate synchronously. There is no situation where one moves and the other does not move. This means that the plastic film on one side will not be damaged in advance, thus ensuring the effect of heat sealing. Furthermore, the first hot-pressing strip 612 has a first clamping groove 613 formed in the middle of its wall surface near the second hot-pressing strip. The first clamping groove extends along the length of the first hot-pressing strip and passes through both ends. The second hot-pressing strip 622 has a second clamping groove 623 formed in the middle of its wall surface near the first hot-pressing strip. The second clamping groove extends along the length of the second hot-pressing strip and passes through both ends. A cutter 614 is provided at the first clamping groove 613, with both ends of the cutter extending through the ends of the second clamping groove. A third through hole 615 is provided in the first push plate 611 corresponding to both ends of the cutter. A fourth push plate 616 is installed at the piston rod end of the first cylinder 630. A second push rod 617 is fixedly provided in the fourth push plate 616 corresponding to the third through hole. The first push plate 611 is penetrated through the third through hole 615; the end of the second push rod is provided with a slot, and the end of the cutter is locked in the slot and fixedly connected by bolts; a gap is left between the fourth push plate and the first push plate to provide space for the fourth push plate to push forward a second time; a third spring 618 is installed between the fourth push plate 616 and the first push plate 611 to maintain the force of pushing the first push plate; the whole is an assembled structure, which can facilitate the processing and production of each structural component and facilitate the disassembly and replacement of parts; the above structural design can drive the cutter forward through the second pushing action of the first cylinder, thereby completing the required slitting action without the need to add an additional drive component for the slitting action, thus reducing costs; It should be noted that the first, second, and third hot pressing strips are relatively common strip-shaped structures, mainly consisting of a mold body and an embedded electric heating tube. Corresponding pressing patterns are set on the mold body. The electric heating tube is connected to electricity for heating, and the mold body conducts heat and performs pressing and shaping. They are common structural components in packaging equipment, and will not be described in detail here. Furthermore, the first push plate has at least two first threaded holes on its wall surface away from the first hot pressing strip, and the first threaded holes are symmetrically arranged about the center of the first push plate; the fourth push plate has a fourth through hole corresponding to the first threaded hole, and a guide bolt 619 is installed at the fourth through hole and the first threaded hole, and the third spring 618 is sleeved on the guide bolt 619; this further strengthens the cooperation between the fourth push plate and the first push plate, and guides and limits the third spring to prevent the third spring from deviating and deforming during compression.

[0022] Furthermore, a guide rod 650 is mounted on the front wall of the third bracket 640 and the chassis 100. A second through hole is correspondingly provided on the first and second push plates, and a second linear bearing is installed at the second through hole. The first and second push plates are slidably mounted on the guide rod via the second linear bearing. A mating plate is fixedly provided at one end of the guide rod, and the mating plate is fixedly mounted on the front wall of the chassis by bolts. Two support rings are fixedly provided on the wall surface of the third bracket near the guide rod. The inner diameter of the support rings matches the diameter of the guide rod, and the end of the guide rod is inserted into the support rings. This structural cooperation further restricts the movement of the first and second push plates, allowing the first and second heat-sealing strips to align and move smoothly, achieving an effective horizontal sealing effect and improving the packaging quality.

[0023] This invention also discloses a packaging method for a Chinese medicinal herb packaging device, comprising the following steps: S1, the film delivery structure and the traction structure work together to achieve film release and shaping; S2, feeding the material to be packaged into the molding machine; S3, the first cylinder and the second cylinder are started. The second cylinder drives the first pusher to move forward a preset distance, so that the two clamping plates are brought closer to each other. The side of the packaging bag is heat-sealed vertically by the third heat-pressing strip. The second cylinder simultaneously drives the second pressing structure to move forward. The first cylinder moves synchronously, driving the first pressing structure to move forward a first preset distance, and the packaging bag containing the material is heat-sealed horizontally by the first hot pressing strip and the second hot pressing strip. S4, the second cylinder remains stationary; the first cylinder pushes forward a second preset distance, compresses the third spring, drives the cutter forward, cuts the horizontally sealed part of the packaging bag, and the product below, which has been separated and dropped, is ready. S5, the first and second cylinders retract their piston rods to reset all structural components; It should be noted that the above steps are based on the premise that the hot press strip has been heated and maintained at the required heat sealing temperature.
