Description

Technical Field

[0001] This utility model relates to the field of can sealing machine technology, specifically a manual can sealing machine for traditional Chinese medicine decoction pieces. Background Technology

[0002] In the production of traditional Chinese medicine (TCM) decoction pieces, the sealing process is crucial for ensuring product quality and extending shelf life. TCM decoction pieces are mostly made from natural medicinal herbs through processing, and their composition is complex, often containing volatile substances, sugars, proteins, and other components. These characteristics make TCM decoction pieces highly susceptible to external environmental factors during storage. Sealing provides a relatively closed environment for TCM decoction pieces, effectively blocking external humidity, oxygen, and pests, maximizing the dryness and stability of the pieces, preventing oxidation and pest damage, and thus maintaining their efficacy and quality. In cases not involving large-scale production, manual sealing machines are favored by individual users, small clinics, or small pharmacies due to their flexibility and low cost, and are often used for packaging small doses and personalized TCM decoction pieces.

[0003] Chinese patent (authorization announcement number: CN 219484017 U, authorization announcement date: 2023.08.08) proposes a hand-cranked can sealing machine. This patent sets up a pressure head assembly with a rotating handle and a roller assembly with a roller handle, so that cans can be sealed by manually turning the rotating handle and holding the roller handle. It also uses a manual screw feeder, so that the can can be raised to the sealing position by manually turning the handle. No power supply is required, making it convenient to operate and flexible in the location of use.

[0004] In practical use, individual or small-batch users may use various diameter containers depending on their needs. For example, small-diameter containers are chosen for sealing small doses of high-value medicinal herbs to facilitate quantity control and portability; large-diameter containers improve efficiency when sealing commonly used medicinal herbs. However, this patent can only accommodate containers of a fixed diameter. When sealing containers of different diameters is required, users must purchase multiple corresponding devices, which not only significantly increases economic costs but also makes the storage and maintenance of multiple devices cumbersome and space-consuming. To adapt to containers of various diameters within a certain range, reduce usage costs, improve operational convenience, and meet the needs of sealing Chinese herbal medicines in different scenarios, we propose a manual sealing machine for Chinese herbal medicines.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 This utility model provides a technical solution: a manual can sealing machine for Chinese herbal medicine slices, including a base plate 1, a back plate 2 fixedly connected to the top of the base plate 1, a top plate 3 fixedly connected to the front side of the back plate 2, a support cover 4 fixedly connected to the top of the base plate 1, a support block 18 slidably connected to the inner wall of the support cover 4, an installation box 6 rotatably connected to the top of the support block 18, a clamping component for clamping the can body installed on the installation box 6, a lifting component for driving the installation box 6 to rise and fall on the support cover 4, a rotating component for driving the can body to rotate on the top plate 3, and a can sealing component for sealing the can on the top plate 3; The clamping assembly includes a mounting post 33, which slides through the mounting box 6. A placement plate 17 is fixedly connected to the top of the mounting post 33. Several sets of sliders 37 are slidably mounted on the mounting box 6. A clamping plate 8 is fixedly connected to the top of the sliders 37. A moving mechanism that moves the clamping plate 8 toward the placement plate 17 is installed on the mounting box 6. A reset mechanism that resets the clamping plate 8 is also installed on the mounting box 6.

[0021] In use, place an appropriate amount of Chinese herbal medicine slices into the jar, then place the jar on the placement plate 17. Under the action of the moving mechanism, the clamping plates 8 move closer to the placement plate 17 until multiple sets of clamping plates 8 clamp the placement plate 17 in the middle. Next, place the jar lid on top of the jar, and the lifting component drives the jar to rise to the rotating component. The rotating component drives the jar and the mounting box 6 to rotate, and at the same time, the sealing component seals the rotating jar. Because the clamping plates 8 can move on the mounting box 6, jars of different diameters within a certain range can be stably clamped by the clamping plates 8 to complete the subsequent sealing operation, thereby reducing the cost of use, improving the convenience of operation, and meeting the needs of sealing Chinese herbal medicine slices in different scenarios.

[0022] The moving mechanism includes several sets of connecting rods 34, which are hinged to the mounting post 33. A sliding rod 36 is hinged to the end of the connecting rod 34 away from the mounting post 33. The end of the sliding rod 36 away from the connecting rod 34 is fixedly connected to the slider 37. Several sets of mounting blocks 35 are fixedly connected to the top of the inner cavity of the mounting box 6. The sliding rod 36 slides through the mounting block 35.

[0023] After the tank is placed on the placement plate 17, the placement plate 17 and the mounting column 33 move down under the gravity of the tank and the Chinese herbal medicine pieces. The sliding rod 36 moves closer to the mounting column 33 through the connecting rod 34, thereby causing the slider 37 to move closer to the mounting column 33, so that the clamping plate 8 moves closer to the placement plate 17.

[0024] The reset mechanism includes several sets of connecting covers 7, which are fixedly connected to the top of the mounting box 6. A sliding cover 39 is slidably installed on the inner wall of the connecting cover 7. The side of the sliding cover 39 away from the connecting cover 7 is fixedly connected to the clamping plate 8. A second spring 38 is fixedly installed on the inner wall of the sliding cover 39. The end of the second spring 38 away from the sliding cover 39 is fixedly connected to the connecting cover 7.

[0025] After sealing, the can is removed. Under the pulling force of the second spring 38, the clamping plate 8 is moved away from the placement plate 17, making it easier to seal the can next time.

[0026] The lifting assembly includes a lifting screw 19, which is rotatably connected to the top of the base plate 1. The lifting screw 19 is threaded into the support block 18. A rotating bevel gear 20 is fixedly sleeved on the outside of the lifting screw 19. A rotating rod 22 is rotatably inserted on the support cover 4. A driving bevel gear 21 is fixedly connected to one end of the rotating rod 22 near the lifting screw 19. The driving bevel gear 21 meshes with the rotating bevel gear 20. A first turntable 5 is fixedly connected to one end of the rotating rod 22 away from the lifting screw 19.

[0027] Rotating the first turntable 5 causes the rotating rod 22 to rotate, which in turn drives the rotating bevel gear 20 to rotate via the driving bevel gear 21. This causes the lifting screw 19 to rotate, which in turn drives the support block 18 to rise and fall, and consequently the mounting box 6 to rise and fall.

[0028] The rotating assembly includes a mounting cylinder 32, which rotates through the top plate 3. A second turntable 10 is fixedly sleeved on the outside of the mounting cylinder 32. A connecting rod 30 is slidably connected to the inner wall of the mounting cylinder 32. A pressure plate 15 is fixedly connected to the bottom of the connecting rod 30. The mounting cylinder 32 is equipped with a disassembly and assembly mechanism that facilitates the replacement of pressure plates 15 of different diameters.

[0029] The lifting assembly raises the tank until the pressure plate 15 presses the tank cover tightly. The second turntable 10 is then rotated to rotate the mounting cylinder 32, which in turn rotates the pressure plate 15, causing the tank and the tank cover to rotate.

[0030] The disassembly and assembly mechanism includes a connecting screw 31, which is fixedly connected to the top of the connecting rod 30. A connecting nut 11 that matches the connecting screw 31 is rotatably installed on the top of the second turntable 10. The connecting nut 11 is threadedly connected to the connecting screw 31.

[0031] Rotating the connecting nut 11 causes the connecting screw 31 to descend, disengaging the connecting screw 31 from the connecting nut 11, allowing the pressure plate 15 of the appropriate specification to be replaced according to the size of the can lid.

[0032] The sealing assembly includes a mounting cover 12, which is slidably mounted on a top plate 3. The top plate 3 has a sliding opening that matches the mounting cover 12. The mounting cover 12 is slidably connected to the sliding opening. A swing frame 9 is rotatably mounted on the bottom of the mounting cover 12. A first pressure roller 13 and a second pressure roller 14 are rotatably mounted on the bottom of the swing frame 9. A fixing mechanism that can fix the position of the mounting cover 12 is installed on the mounting cover 12.

[0033] The mounting cover 12 drives the swing frame 9 to a suitable position. The mounting cover 12 is fixed by the fixing mechanism. The swing frame 9 is held and pulled forward so that the first pressure roller 13 is pressed against the edge of the can lid. As the can rotates, a certain radial pressure is applied to the edge of the can lid, so that the edge of the can lid begins to gradually bend downward, forming a preliminary rolled edge shape. Then the swing frame 9 is pulled backward so that the second pressure roller 14 is pressed against the can lid. The edge of the can lid is further rolled and pressed, so that it fits more tightly with the rolled edge of the can, thus completing the sealing.

[0034] The fixing mechanism includes two sets of limiting blocks 23, which are slidably connected to the inner wall of the mounting cover 12. Several sets of first springs 29 are fixedly installed between the two sets of limiting blocks 23. Connecting blocks 24 are fixedly connected to the side of the two sets of limiting blocks 23 that are close to each other. A sliding block 27 is slidably passed through the mounting cover 12. A pressure block 28 is fixedly connected to the bottom of the sliding block 27. A first inclined surface is provided on the side of the two sets of connecting blocks 24 that are close to the pressure block 28. A second inclined surface matching the first inclined surface is provided on the pressure block 28. A moving mechanism that drives the sliding block 27 to rise and fall is installed on the mounting cover 12.

[0035] The moving mechanism includes a knob 25, which is rotatably mounted on the top of the mounting cover 12. A limit screw 26 is fixedly connected to the top of the inner cavity of the knob 25, and the limit screw 26 is threaded into the sliding block 27.

[0036] Rotating the knob 25 causes the limiting screw 26 to rotate, causing the sliding block 27 to move down, which in turn causes the pressure block 28 to move down. Through the cooperation of the first inclined surface and the second inclined surface, the two sets of limiting blocks 23 move away from each other, and the limiting blocks 23 press against the inner wall of the sliding opening to fix the position of the mounting cover 12.

[0037] Several sets of suction cups 16 are fixedly connected to the bottom of the base plate 1.

[0038] Working principle: In use, place an appropriate amount of Chinese herbal medicine slices into the jar, and then place the jar on the placement plate 17. Under the weight of the jar and the Chinese herbal medicine slices, the placement plate 17 and the mounting column 33 move downwards. Through the connecting rod 34, the sliding rod 36 moves closer to the mounting column 33, thereby causing the slider 37 to move closer to the mounting column 33, and the clamping plate 8 moves closer to the placement plate 17 until multiple sets of clamping plates 8 clamp the placement plate 17 in the middle. Next, place the jar lid on top of the jar, rotate the first turntable 5 to drive the rotating rod 22 to rotate, and drive the rotating bevel gear 20 to rotate through the driving bevel gear 21. Then the lifting screw 19 rotates, driving the support block 18 to rise, driving the mounting box 6 to rise, and driving the jar to rise until the pressure plate 15 presses the jar lid tightly. Rotate the second turntable 10 to drive the mounting cylinder 32 to rotate, driving the pressure plate 15 to rotate, causing the jar and jar lid to rotate. The installation cover 12 moves the swing frame 9 to a suitable position. Turning the knob 25 rotates the limiting screw 26, causing the sliding block 27 to move downwards, which in turn moves the pressure block 28 downwards. The first and second inclined surfaces work together to move the two sets of limiting blocks 23 away from each other, with the limiting blocks 23 pressing against the inner wall of the sliding opening, fixing the position of the installation cover 12. Holding the swing frame 9 and pulling it forward causes the first pressure roller 13 to press tightly against the edge of the can lid. As the can rotates, a certain radial pressure is applied to the edge of the can lid, causing it to gradually bend downwards, forming a preliminary rolled edge shape. Then, the swing frame 9 is pulled backwards, causing the second pressure roller 14 to press tightly against the can lid. The edge of the can lid is further rolled and pressed, making it fit more closely with the rolled edge of the can, thus completing the sealing. After sealing, the can is removed. Under the tension of the second spring 38, the clamping plate 8 moves away from the placement plate 17, facilitating the next sealing. During the sealing process, since the clamping plate 8 can move on the mounting box 6, cans of different diameters within a certain range can be stably clamped by the clamping plate 8. By rotating the connecting nut 11, the connecting screw 31 is driven to descend, causing the connecting screw 31 to disengage from the connecting nut 11. The pressure plate 15 of the corresponding specification can be replaced according to the size of the can lid. This allows the sealing machine to be adapted to cans of different diameters within a certain range, thereby reducing the cost of use, improving the convenience of operation, and meeting the needs of sealing Chinese herbal medicine slices in different scenarios.
