Description

Technical Field

[0001] The utility model belongs to the field of Chinese medicine slice packaging, in particular to a Chinese medicine slice bagging machine. Background Art

[0002] Chinese herbal medicines can be used to prevent, treat, and diagnose diseases under the guidance of traditional Chinese medicine theory, and they have rehabilitation and health-care effects. After the production of Chinese herbal medicines is completed, they need to be bagged to facilitate their storage and transportation.

[0003] When bagging Chinese herbal medicine slices, the film bag is typically sealed longitudinally first by a longitudinal sealing mechanism, followed by quantitative feeding and bagging via a material guide. After bagging is complete, the film bag is then sealed transversely by a transverse sealing mechanism. This requires two heat-sealing steps to form a bag, resulting in low heat-sealing efficiency and thus impacting bagging efficiency. Furthermore, during this process, the film bag is clamped and rotated by traction wheels to pull the bag. Because the distance between the two traction wheels is generally difficult to adjust, the film bag is typically inserted directly into the two traction wheels during installation, which is cumbersome and cannot accommodate packaging films of varying thicknesses.

It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0018] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0019] Combine Figure 1-4 As shown, the Chinese medicine slice bagging machine includes a machine 1, and the machine 1 is provided with a fixed frame 2, a material guide seat 3, a heat sealing mechanism, a film pulling mechanism, and a cutting mechanism in sequence from top to bottom. The fixed frame 2 is rotatably provided with a reeling wheel 4, and the film pulling mechanism includes a fixed seat 5 and a slide seat 6 installed in the machine 1. The front of the machine 1 is provided with a pair of left and right adjustment slots 7 facing the slide seat 6. The fixed seat 5 and the slide seat 6 are respectively rotated outward with a rotating rod 9 and an adjusting rod 10. The rotating rod 9 and the adjusting rod 10 are respectively rotated outward. The rods 10 all pass through the machine and are provided with a traction wheel 11, and the adjustment rod 10 is located in the left adjustment slot 7. The film pulling mechanism includes a locking nut 12, and a pressing sleeve 13 is provided on the locking nut 12. The end of the locking nut 12 passes through the right adjustment slot and is screwed into the slide 6 and locked. The tail of the rotating rod 9 and the tail of the adjustment rod 10 are both provided with a transmission gear 14, and the two transmission gears 14 are engaged. The fixed seat 8 is also provided with a drive motor 15 for driving the rotating rod 9 to rotate.

[0020] Chinese herbal medicine slices can be used to prevent, treat, diagnose diseases and have rehabilitation and health-care effects under the guidance of traditional Chinese medicine theory. When the Chinese herbal medicine slices are produced, they can be bagged by this bagging machine to facilitate the storage and transportation of the Chinese herbal medicine slices.

[0021] In this structure, if Figure 1 The fixed frame 2 is provided with a guide rod 16. Before bagging the Chinese herbal medicine slices, the rolled packaging film bag is first mounted on the unwinding wheel as required. The packaging film bag then passes through the guide rod, the material guide seat, the heat sealing mechanism, and the film pulling mechanism in sequence. The material guide seat is located within the packaging film bag, and the packaging film bag is closely attached to the material guide seat. In actual operation, the top surface of the machine is also equipped with a filling mechanism. The Chinese herbal medicine slices are loaded into the filling mechanism, and the filling mechanism outlet is connected to the top of the material guide seat. However, the filling mechanism is not the focus of this bagging machine and will not be discussed here.

[0022] When the packaging film bag passes through the heat sealing mechanism under the traction of the film pulling mechanism, the heat sealing mechanism heat-seals the packaging film bag inside it to form the current packaging bag with an opening. After the Chinese herbal medicine slices are quantitatively loaded into the current packaging bag through the material guide seat, the film pulling mechanism continues to pull the packaging film bag, and the heat sealing mechanism heat-seals the packaging film bag inside it again to form the next packaging bag with an opening, completing the sealing of the current packaging bag at the same time. The Chinese herbal medicine slices continue to be loaded into the next packaging bag, and so on. After sealing, each packaging bag moves toward the cutting mechanism in order. The cutting mechanism cuts off the sealing position at the top of the packaging bag, and the cut packaging bag falls.

[0023] As the film-pulling mechanism pulls the film bag, it moves between the two traction wheels, which clamp the bag. The drive motor then drives the rotating rod, which in turn causes the two meshing transmission gears to rotate simultaneously. This causes both traction wheels to rotate simultaneously, driving the film bag downward. As the film bag moves, the unwinding wheel rotates, unwinding the film.

[0024] When a packaging film bag is to be passed through the film-pulling mechanism, the distance between the two traction wheels must first be fine-tuned. This involves loosening the locking nut. Then, by pulling the locking nut, the slide moves outward a short distance, moving the right traction wheel slightly away from the left, creating a gap. The corresponding position of the packaging film bag can now be passed through the gap. The locking nut is then pulled to move the slide inward a short distance until the left and right traction wheels clamp the packaging film bag. Finally, the locking nut is tightened again. As the locking nut is tightened, the compression sleeve moves toward the machine platform until it presses against the platform, locking the slide and preventing it from sliding. This makes the entire process relatively simple and saves time and effort.

[0025] Since the distance between the left and right traction wheels can be fine-tuned by adjusting the right traction wheel, it not only facilitates the installation of the packaging film bag, but also allows the traction wheel to clamp the packaging film bag, improving the stability when traction of the packaging film bag. It can also adapt to packaging film bags of different thicknesses.

[0026] As a preferred structure, Figure 1-2 The heat sealing mechanism includes a pair of side plates 17, a pair of sliding rods 18 are provided between the two side plates 17, a pair of slide plates 19 are slidably provided on the slide rods 18, an L-shaped heating sealing knife 20 is provided on the inner side of the slide plate 19, and the lower part of the material guide seat 3 is located between the two heating sealing knives 20. The back of the side plate 17 is also provided with a sliding cylinder 21 for driving the slide plate 19 to slide.

[0027] In the above structure, the heating blades are designed to be L-shaped. When the left and right heating blades are used to heat-seal the packaging film bag in the heat-sealing mechanism, the vertical and horizontal heat-seals of the packaging film bag can be completed at the same time, forming a package with an opening, which makes the overall heat-sealing efficiency higher.

[0028] Specifically, when the heat sealing mechanism is used for heat sealing, the sliding cylinder simultaneously drives the two slides to slide inward until the heating sealing knife contacts and squeezes the packaging film bag, and then the heating sealing knife is reset to form a package with an opening, and the sealing action of the previous package is completed at the same time.

[0029] Further as a preferred structure, Figure 1-2 、 Figure 4 The cutting mechanism includes a vertically adjustable cutting frame 22 with a blanking opening 23. A pair of left and right cutters are located within the cutting frame 22, with the left cutter being designated 241 and the right cutter being designated 242. The left cutter 241 is fixedly mounted, while the right cutter 242 is slidably mounted, with the left cutter positioned above the right cutter. A cutting motor 25 is mounted on the cutting frame 22, and a cutting cam 26 is mounted on the drive shaft of the cutting motor 25. A pull rod 27 is rotatably mounted at an eccentric position of the cutting cam 26, which is rotatably connected to a corresponding position of the right cutter 242.

[0030] In this structure, the height of the cutting frame can be adjusted to fine-tune the cutting position. When a sealed bag enters the cutting frame from the blanking port, the top of the bag and the sealed position are located between the left and right cutters. The cutting motor then drives the cutting cam to rotate. During this rotation, the pull rod first pushes the right cutter toward the left cutter until both cutters complete the bag cutting. The pull rod then pulls the right cutter back to its original position, preparing to cut the next bag.

[0031] A blanking rack 28 is provided on the machine 1 below the blanking port 23. The packaging bags cut by the cutting mechanism fall onto the blanking rack and slide from the blanking rack to the blanking station for centralized collection.

[0032] In addition, if Figure 1-2 The machine 1 is provided with an adjustment frame 29, an adjustment seat 30 is slidably provided on the adjustment frame 29, the cutting frame 22 is provided on the adjustment seat 30, an adjustment screw rod 31 is inserted into the top of the adjustment frame 30, and the bottom of the adjustment screw rod 31 is screwed out of the adjustment seat 30, and a turntable 32 is also provided on the top of the adjustment screw rod 31.

[0033] When the cutting frame needs to be fine-tuned, it can be done by rotating the turntable. That is, when the turntable rotates, the adjusting screw rotates synchronously, and the adjusting seat moves along the height position of the adjusting screw, and the cutting frame moves synchronously until it is fine-tuned to the required position.

[0034] The present invention is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
