Description

Technical Field

[0001] This utility model relates to the field of Chinese medicinal material processing equipment, and in particular to a device for peeling stem medicinal materials. Background Technology

[0002] Traditional Chinese medicinal herbs are the foundation for the inheritance and development of traditional Chinese medicine and an important component of its pharmacology. Stem-type medicinal herbs are a type of medicinal herb, generally referring to the stem portion used as medicine. Some stem-type herbs require peeling, such as yam, arisaema, *Homalomena occulta*, and *Trichosanthes kirilowii*. Currently, peeling stem-type medicinal herbs has been mechanized, and many peeling devices exist. Many of these use roller scraping methods, such as the fresh medicinal herb peeling machine disclosed in patent CN118902120A. This machine uses three rotating rollers, each with a roughened outer surface, brushes, and raised dots. The three rollers work together to peel the fresh medicinal herbs. While this patented technology can effectively peel the herbs, it often creates uneven surfaces with bumps and pits. Furthermore, the uneven surfaces can easily produce black spots due to incomplete scraping. Utility Model Content

[0003] Existing technologies often employ roller scraping to remove the skin, as disclosed in the aforementioned patent. While this method effectively removes the skin, it frequently results in uneven surfaces with bumps and pits. Furthermore, incomplete scraping between these bumps can easily lead to the formation of numerous black spots. This application designs a skinning device for stem-type medicinal materials, which addresses at least one aspect or objective of these problems. The technical solution adopted is as follows:

[0004] A device for peeling stem-type medicinal materials, comprising:

[0005] The support frame has at least two first guide grooves horizontally, and the at least two first guide grooves are symmetrically arranged with respect to the center of the support frame. The support frame also has at least two second guide grooves horizontally, and the at least two second guide grooves are symmetrically arranged with respect to the center of the support frame.

[0006] The clamping disc is slidably disposed within the first guide groove;

[0007] A first driving component is disposed on the support frame and is connected to the clamping disk, driving the clamping disk to slide along the first guide groove;

[0008] The scraper disc is slidably disposed in the second guide groove;

[0009] The second driving component is mounted on the support frame and connected to the scraper disc. It drives the scraper disc to slide along the second guide groove. The maximum distance that the clamping disc moves unidirectionally toward the scraper disc is less than the distance that the scraper disc moves unidirectionally toward the clamping disc.

[0010] Preferably, the scraper disc includes:

[0011] The outer ring body is slidably disposed in the second guide groove;

[0012] The scraper assembly has one end fixed to the outer ring body and the other end located inside the outer ring body;

[0013] The telescopic cylinder has a vertical outer ring body set on its inner wall, and the telescopic rod of the telescopic cylinder can abut against the scraper assembly by extending and retracting.

[0014] Preferably, the scraper assembly includes:

[0015] The cutter head is fixed to the outer ring body;

[0016] At least three tool holders are evenly spaced along the circumference of the tool disc. One end of each of the at least three tool holders is movably mounted on the tool disc via a torsion spring, and the other end extends to one side. The number of telescopic cylinders is the same as the number of tool holders. The telescopic rod end of the telescopic cylinder can abut against the end of the tool holder away from the tool disc.

[0017] The number of scrapers is the same as that of the blade holders, and each blade holder is equipped with a scraper.

[0018] Preferably, a buffer plate is provided between each tool holder and the scraper on it. The buffer plate is set on the inner wall of the tool holder by a spring, and the scraper is set on the buffer plate.

[0019] Preferably, each clamping disc includes:

[0020] An outer clamping ring body is slidably disposed in the first guide groove;

[0021] At least two clamping telescopic cylinders are evenly spaced along the circumference of the outer clamping ring. Each clamping telescopic cylinder is vertically arranged on the inner wall of the outer clamping ring, and its telescopic rod end is connected to a clamping plate.

[0022] Preferably, the first guide groove is a through groove, and the clamping disk is provided with first lugs symmetrically on the outer side of the circumference. The two first lugs are connected by a first connecting rod, and the first connecting rod is connected to a first driving component provided at one end of the support frame.

[0023] Preferably, the first driving component is a first telescopic cylinder.

[0024] Preferably, the second guide groove is also a through groove, and two second lugs are symmetrically provided on the outer circumference of the scraper disc. The two second lugs are connected to the second drive component through the second connecting rod.

[0025] Preferably, the second driving component is a second telescopic cylinder.

[0026] This invention uses a clamping disc and a scraping disc to peel stem-type medicinal materials. Specifically, the clamping disc holds the stem-type medicinal materials and continuously conveys them forward, while the scraping disc scrapes the stem-type medicinal materials to remove the skin.

Detailed Implementation

[0032] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0033] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] like Figure 1-4As shown, a device for peeling stem-type medicinal materials includes a support frame 2, a clamping disc 8, a first driving component 4, a scraper disc 7, and a second driving component 6. The support frame 2 can be a circular ring or a cuboid frame. Two first guide grooves 3 are horizontally arranged on the support frame 2; alternatively, three, four, etc., can be provided, depending on the specific requirements. The two first guide grooves 3 are symmetrically arranged relative to the center of the support frame 2. Two second guide grooves 5 are also horizontally arranged on the support frame 2; alternatively, three, four, etc., can be provided, depending on the specific requirements. The two second guide grooves 5 are symmetrically arranged relative to the center of the support frame 2. The second guide grooves 5 and the first guide grooves 3 are arranged side-by-side in the horizontal direction without overlap.

[0035] The aforementioned clamping disk 8 is slidably disposed in the first guide groove 3 and connected to the first driving component 4, driving the clamping disk 8 to slide synchronously along the first guide groove 3.

[0036] The aforementioned scraper disc 7 is the main component for peeling. The scraper disc 7 is slidably mounted on the second guide groove 5. The scraper disc 7 is connected to the second drive component 6 mounted on the support frame 2, which drives the scraper disc 7 to slide along the second guide groove 5. To avoid the scraper disc 7 missing any peeling at the dividing line between two peeling sections, the maximum distance that the clamping disc 8 moves unidirectionally toward the scraper disc 7 is less than the unidirectional distance that the scraper disc 7 moves toward the clamping disc 8. In this way, when the scraper disc 7 peels the next section, it will always have a small overlap with the previous section, ensuring a seamless connection.

[0037] Furthermore, specifically, the scraper disc 7 includes an outer ring body 701, a scraper assembly, and a telescopic cylinder 703. The outer ring body 701 is slidably disposed in the second guide groove 5, and the scraper assembly is disposed on the outer ring body 701. Specifically, the left end of the scraper assembly is fixed to the outer ring body 701, and the right end is located inside the outer ring body 701. The telescopic cylinder 703 is vertically disposed on the inner wall of the outer ring body 701, and the telescopic rod end of the telescopic cylinder 703 can abut against the right end of the scraper assembly. Preferably, the telescopic cylinder 703 is a pneumatic cylinder or a hydraulic cylinder, because the movement of the telescopic cylinder 703 can be uniformly controlled through the same pneumatic or hydraulic system, ensuring the consistency of the movement of multiple telescopic cylinders 703.

[0038] The telescopic cylinder 703 is positioned against the right end of the scraper assembly to facilitate contact and separation between the scraper assembly and the stem-type medicinal materials.

[0039] Furthermore, the aforementioned scraper assembly includes a cutter disc 708, at least three cutter holders 702, and scrapers 707. The cutter disc 708 is fixed to the outer ring body 701 by existing connection methods such as bolts, screws, or interference fit. In this application, three cutter holders 702 are selected. The three cutter holders 702 are evenly spaced along the circumference of the cutter disc 708. The left ends of the three cutter holders 702 are movably mounted on the cutter disc 708 by torsion springs 704, and the right ends extend to one side. The number of telescopic cylinders 703 is the same as the number of cutter holders 702. The telescopic rod end of the telescopic cylinder 703 can abut against the end of the cutter holder 702 away from the cutter disc 708. The number of scrapers 707 is the same as the number of cutter holders 702. Each cutter holder 702 is provided with one scraper 707. Under the action of the torsion spring 704, the knife holder 702 is initially open (meaning that after the stem-type medicinal material is inserted into the scraper disc 7, the scraper 707 does not contact the outer skin of the stem-type medicinal material in the initial state). The telescopic rod of the telescopic cylinder 703 extends out and squeezes the knife holder 702 to overcome the elastic force of the torsion spring 704 and tighten it inward, thereby driving the scraper 707 to contact the outer skin of the stem-type medicinal material and then scrape the skin.

[0040] The specific operation process of the clamping disc 8 and scraper disc 7 is as follows: First, both the clamping disc 8 and scraper disc 7 are in their initial state (i.e., the clamping telescopic cylinder 803 is not clamping and the blade holder 702 is not being squeezed). The stem-type medicinal material is manually lowered to the scraper disc 7 in one go, and the machine is turned on. At this time, the clamping telescopic cylinder 803 of the clamping disc 8 clamps the stem-type medicinal material, and at the same time, the telescopic cylinder 703 of the scraper disc 7 squeezes the blade holder 702, bringing the scraper 707 into contact with the outer skin of the stem-type medicinal material. Then, the second drive component 6 drives the scraper disc 7 to move to the left to scrape the skin. After scraping a certain distance, the telescopic cylinder 703 of the scraper disc 7 retracts to release the stem-type medicinal material, and then the second drive component 6 reverses to drive the scraper disc 7 back to its initial position. Then, the clamping telescopic cylinder 803 of the clamping disc 8 retracts to release the stem-like medicinal material. Subsequently, the first driving component 4 drives the clamping disc 8 to move to the left a certain distance, and the clamping telescopic cylinder 803 extends to clamp the stem again. At the same time, the first driving component 4 reverses to drive the clamping disc 8 to move to the right until it moves to the part that has not been peeled and approaches the scraper disc 7. The telescopic cylinder 703 on the scraper disc 7 extends, and the scraper 707 contacts the stem-like medicinal material to peel it again. The above steps are repeated until the stem-like medicinal material is peeled.

[0041] It should be noted that when scraping the bark of stem-type medicinal materials, due to the clamping mechanism of the clamping disc 8, there may be areas at the end of the stem-type medicinal materials that cannot be scraped off. This can be corrected manually and will not affect the use of the device.

[0042] Furthermore, in reality, many stem-type medicinal materials are not straight; they may have bent or twisted sections. To prevent these bent or twisted sections from breaking the stem-type medicinal materials due to rigid contact, a buffer plate 706 is provided between each blade holder 702 and the scraper 707 on it. The buffer plate 706 is set on the inner wall of the blade holder 702 via a spring 705, and the scraper 707 is set on the buffer plate 706. The telescopic rod of the telescopic cylinder 703 presses against the blade holder 702, thereby causing the buffer plate 706 on it to come into contact with the stem-type medicinal materials until the buffer plate 706 presses the stem-type medicinal materials firmly. When a section of the stem-type medicinal materials is bent or twisted, in order to adapt to the shape of the stem-type medicinal materials, the buffer plate 706 can make slight movements at any angle under the action of the spring 705, avoiding rigid contact that could damage the stem-type medicinal materials.

[0043] Furthermore, the structure of each clamping disc 8 specifically includes an outer clamping ring 801 and at least two clamping telescopic cylinders 803. The outer clamping ring 801 is slidably disposed in the first guide groove 3. In this application, two clamping telescopic cylinders 803 are provided. The two clamping telescopic cylinders 803 are evenly spaced along the circumference of the outer clamping ring 801. Each clamping telescopic cylinder 803 is vertically disposed on the inner wall of the outer clamping ring 801, and its telescopic rod end is connected to a clamping plate 802. The clamping telescopic cylinder 803 extends out and directly uses the clamping plate 802 on it to clamp the stem medicinal material.

[0044] Furthermore, the first guide groove 3 is a through groove, and two first lugs 9 are symmetrically provided on the outer circumference of the clamping disk 8. The two first lugs 9 are connected by a first connecting rod 10. The first connecting rod 10 is connected to the first driving component 4 provided at one end of the support frame 2. In this way, the two first lugs 9 are set through the through groove and connected to the first connecting rod 10 together, which can reduce the force imbalance when the clamping disk 8 slides in the first guide groove 3.

[0045] Furthermore, the first drive component 4 mentioned above adopts a first telescopic cylinder. The first telescopic cylinder is preferably a pneumatic cylinder or a hydraulic cylinder, because pneumatic cylinders and hydraulic cylinders can easily control the action of multiple telescopic cylinders using the same air circuit and hydraulic circuit, thus ensuring the consistency of action.

[0046] In alternative embodiments, unless otherwise specified, the first drive component 4 can also be a conventional lead screw and nut drive.

[0047] Furthermore, the second guide groove 5 is also a through groove, and two second lugs 11 are symmetrically provided on the outer circumference of the scraper disc 7. The two second lugs 11 are connected to the second drive component 6 through the second connecting rod 1.

[0048] Preferably, the second drive component 6 is a second telescopic cylinder.

[0049] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0050] Any aspects of this utility model not described in detail are known to those skilled in the art.
