Description

Technical Field

[0001] This utility model relates to the technical field of medicinal material processing equipment, specifically to a medicinal material slicing device. Background Technology

[0002] A medicinal herb slicing device is a mechanical device specifically designed for processing Chinese medicinal herbs. It is mainly used to cut dried or semi-dried roots, fruits, bark, and other medicinal materials into uniform thin slices. The characteristics of a medicinal herb slicing device are its small size, simple operation, and suitability for small-batch processing. It falls between traditional manual slicing and large industrial slicing machines, and is widely used in Chinese pharmacies, clinics, medicinal herb growers, and home settings.

[0003] In the prior art, for example, Chinese utility model patent application dated May 6, 2023, and authorization announcement number CN219685837U discloses a medicinal herb slicing machine, which mainly includes a machine body, a top plate of the machine body, a discharge hopper, a feeding device, a slicing mechanism, and a driving mechanism. This slicing machine slices medicinal materials using blades of the slicing mechanism, which is simple to operate and safe and reliable, preventing accidents such as hand injuries. Furthermore, the thickness of the slicing gap between the blade and the blade holder is adjustable, thereby effectively adjusting the slicing thickness of the medicinal materials.

[0004] However, the aforementioned slicer primarily adjusts the blade height by adjusting the height of two first screws. After adjusting the blade height, a blade clamping plate is needed to tighten and secure the blade. In other words, when adjusting the slice thickness, the top panel of the machine must first be opened, then the blade height adjusted one by one using the first screws. After adjusting the blade height, the blade clamping plate is used to secure the blade using the second screw, and finally, the top panel must be reinstalled. Therefore, the existing medicinal herb slicing device involves a cumbersome operation process and low adjustment efficiency when adjusting the slice thickness. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a medicinal herb slicing device to solve the issues of cumbersome operation and low adjustment efficiency in the existing medicinal herb slicing devices when adjusting the slice thickness.

[0006] This utility model is achieved using the following technical solution: a medicinal herb slicing device, including a machine housing, a feed inlet on the top of the machine housing, a discharge hopper installed inside the machine housing, a limiting plate rotatably mounted inside the machine housing and driven to rotate by a drive mechanism, the limiting plate being located above the discharge hopper, a cutting disc for cutting medicinal herbs being installed above the limiting plate, the cutting disc rotating synchronously with the limiting plate, and a feeding hole for medicinal herb slices to pass through on the limiting plate; an adjusting seat rotatably connected to the middle of the cutting disc, which can drive the cutting disc to move up and down, and an adjusting mechanism for adjusting the position of the adjusting seat being provided on the top of the machine housing.

[0007] With the above structure, when the slice thickness needs to be adjusted, the position of the adjusting seat can be adjusted simply by adjusting the adjusting mechanism. The position of the limiting plate is fixed. After the slice thickness is adjusted, the gap between the slice thickness and the limiting plate will change. Adjusting the slice thickness only requires adjusting the position of the adjusting seat, making the operation simple and the adjustment efficiency higher.

[0008] Preferably, the cutter head includes a mounting sleeve fitted onto the outside of the adjusting seat, the mounting sleeve rotatably engaging with the adjusting seat, and a plurality of blades arranged in a circumferential array fixedly mounted on the outside of the adjusting seat, with a common annular connecting plate fixedly connected to the ends of the blades away from the mounting sleeve; the feed hole is located below the blades. The mounting sleeve allows the adjusting seat to move the entire cutter head up and down, and the connecting plate further stabilizes the overall structure of the cutter head.

[0009] Preferably, the adjustment mechanism includes an adjustment sleeve fixedly installed on the top of the machine housing. The inner side of the adjustment sleeve has an internal thread, and a screw with an external thread is threaded onto the inner thread of the adjustment sleeve. An adjustment knob is fixedly connected to the top of the screw, which is located above the machine housing. The bottom end of the screw is fixedly connected to an adjustment seat. A fastening plate with an internal thread is also threaded onto the screw, located between the adjustment knob and the adjustment sleeve. Through the arrangement of the screw and adjustment sleeve, when the blade position needs to be adjusted, the device only needs to rotate the screw, which will move the adjustment seat up and down, thereby adjusting the slice thickness. The entire operation can achieve zero contact with the blade, making it safer and more convenient.

[0010] Preferably, the side of the adjusting seat is provided with an annular limiting groove, and the inner wall of the mounting sleeve is provided with an annular limiting block. The limiting block is inserted into and slidably engaged with the limiting groove. The limiting groove and the limiting block allow the mounting sleeve to slide relative to the adjusting seat while also moving up and down under the influence of the adjusting seat.

[0011] Preferably, the limiting plate is disc-shaped, and a synchronizing ring is fixedly connected to the outer side of the limiting plate. The inner wall of the synchronizing ring has several grooves, and several protrusions are fixedly connected to the outer side of the connecting plate. The protrusions are located within the grooves and can slide up and down within the grooves. Through the arrangement of the grooves and protrusions, the cutter head can rotate synchronously with the limiting plate and also move up and down under the influence of the adjusting seat.

[0012] Preferably, a fixed sleeve is fixedly connected to the discharge hopper. The top end of the fixed sleeve is rotatably engaged with the limiting plate, and a third rotating shaft is rotatably installed inside the fixed sleeve. The top end of the third rotating shaft is fixedly connected to the limiting plate, and the bottom end is rotatably engaged with the machine housing. The fixed sleeve facilitates the installation of the limiting plate and the third rotating shaft.

[0013] Preferably, the drive mechanism includes a motor fixedly installed inside a housing. A second rotating shaft is coaxially fixedly connected to the motor's output shaft. A mounting plate is fixedly connected inside the housing, and the end of the second rotating shaft furthest from the motor is rotatably engaged with the mounting plate. A driving bevel gear is coaxially fixedly connected to the second rotating shaft. A first rotating shaft is rotatably connected to the bottom of the housing. A driven bevel gear meshing with the driving bevel gear is coaxially fixedly connected to the top of the first rotating shaft. A driving pulley is also coaxially fixedly connected to the first rotating shaft. A driven pulley is coaxially fixedly connected to the bottom of a third rotating shaft. The driving pulley and the driven pulley are engaged by a transmission belt. By using the driving and driven pulleys, the slicing and driving functions of the slicing device can be separated into two spaces, reducing mutual interference and facilitating installation.

[0014] Preferably, slide rails are fixedly connected to both sides of the front end of the chassis, and a sliding plate for blocking the cutter head is slidably installed between the two slide rails. The sliding plate prevents operators from accidentally touching the cutter head and causing injury, thus enhancing safety.

[0015] Preferably, a support plate is fixedly connected to the top of the slide plate, and the support plate overlaps with the top of the chassis. The support plate facilitates the removal of the slide plate and makes subsequent maintenance of the cutter head easier.

[0016] Preferably, the bottom of the feed inlet is provided with a downward-extending feed pipe, the bottom of which is located above the cutting disc. This feed pipe design allows for more stable slicing of the medicinal materials.

[0017] In summary, the beneficial effects of this utility model are as follows: The synchronous ring allows the blade disc to rotate synchronously with the limiting plate. Furthermore, the adjusting seat allows for adjustment of the distance between the blade disc and the limiting plate without affecting the blade disc's rotation, thereby adjusting the slice thickness. During adjustment, the screw's up-and-down movement is controlled simply by rotating a knob on the outside of the machine housing, thus adjusting the slice thickness. The entire adjustment process is simpler and faster, resulting in higher efficiency. Moreover, there is zero contact between the operator and the blade during adjustment, further reducing the risk of cuts and making the operation safer. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., 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 application 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 application.

[0022] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0023] like Figure 1 , Figure 3 , Figure 4As shown, this utility model provides a medicinal herb slicing device, including a housing 1. The housing 1 is divided into two areas, a slicing chamber 2 and a drive chamber 12, by a partition. A drive mechanism is installed in the drive chamber 12, and a discharge hopper 3 is fixedly installed in the slicing chamber 2. A cutting device is also installed in the slicing chamber 2. A feed inlet 27 is provided on the top plate of the slicing chamber 2 of the housing 1. The cutting device includes a limiting plate 35 that can be driven to rotate by the drive mechanism. The limiting plate 35 is located above the discharge hopper 3. A cutting disc 28 for cutting medicinal herbs is installed above the limiting plate 35. The cutting disc 28 rotates synchronously with the limiting plate 35. A feeding hole 36 is provided on the limiting plate 35 for the medicinal herb slices to pass through. An adjusting seat 29 that can drive the cutting disc 28 to move up and down is rotatably connected to the middle of the cutting disc 28. An adjusting mechanism for adjusting the position of the adjusting seat 29 is provided on the top of the housing 1.

[0024] The aforementioned adjustment mechanism can be any mechanism capable of moving the adjustment seat 29 up and down. For example, a cylinder can be installed on the top of the housing 1, with its output end fixedly connected to the adjustment seat 29, thereby moving the adjustment seat 29 up and down via the cylinder. However, in this embodiment, the adjustment mechanism mainly includes an adjustment sleeve 8 fixedly installed on the top of the housing 1. The inner side of the adjustment sleeve 8 is provided with an internal thread, and a screw 10 with an external thread is threaded into the inner side of the adjustment sleeve 8. An adjustment knob 11 is fixedly connected to the top of the screw 10, and the adjustment knob 11 is located above the housing 1. The bottom end of the screw 10 is fixedly connected to the adjustment seat 29. A fastening plate 9 with an internal thread is also threaded into the screw 10, and the fastening plate 9 is located between the adjustment knob 11 and the adjustment sleeve 8.

[0025] When the height of the adjusting seat 29 needs to be adjusted, simply rotate the fastening plate 9 to move it away from the adjusting sleeve. At this time, the screw 10 can be rotated by the adjusting knob 11, thereby changing the position of the adjusting seat 29. After the position of the adjusting seat 29 is determined, move the fastening plate 9 towards the adjusting sleeve 8. When the fastening plate 9 contacts the adjusting sleeve 8, continue to tighten it, which will generate axial pressure. This pressure will generate a huge static friction between the fastening plate 9 and the adjusting sleeve 8. The end face pressing friction of the fastening plate 9 and the adjusting sleeve 8 and the threaded friction work together to lock the screw 10 and prevent it from being driven to rotate by the cutter head 28.

[0026] like Figure 4 , Figure 6 , Figure 7As shown, the cutter head 28 includes a mounting sleeve 30 that fits onto the outside of the adjusting seat 29. The mounting sleeve 30 is rotatably engaged with the adjusting seat 29. Specifically, the adjusting seat 29 has an annular limiting groove 37 on its side, and the mounting sleeve 30 has an annular limiting block 38 on its inner wall. The limiting block 38 is inserted into and slidably engaged with the limiting groove 37. Several blades 31 arranged in a circular array are fixedly mounted on the outside of the adjusting seat 29. The ends of the blades 31 away from the mounting sleeve 30 are fixedly connected to a common annular connecting plate 32. The feed hole 36 is located below the blades 31.

[0027] like Figure 4 , Figure 5 As shown, the limiting plate 35 is disc-shaped, and a synchronous ring 25 is fixedly connected to the outer side of the limiting plate 35. Several grooves 34 are provided on the inner wall of the synchronous ring 25. Several protrusions 33 are fixedly connected to the outer side of the connecting plate 32. The protrusions 33 are located in the grooves 34 and can slide up and down in the grooves 34.

[0028] A fixed sleeve 23 is fixedly connected to the discharge hopper 3. The top end of the fixed sleeve 23 is rotatably engaged with the limiting plate 35. A third rotating shaft 24 is rotatably installed inside the fixed sleeve 23. The top end of the third rotating shaft 24 is fixedly connected to the limiting plate 35, and the bottom end is rotatably engaged with the machine box 1.

[0029] like Figure 2 , Figure 3 As shown, the drive mechanism in this embodiment includes a motor 13 fixedly installed in the drive chamber 12 of the chassis 1. A second rotating shaft 20 is coaxially fixedly connected to the output shaft of the motor 13. A mounting plate 19 is fixedly connected inside the chassis 1. The end of the second rotating shaft 20 away from the motor 13 is rotatably engaged with the mounting plate 19. A driving bevel gear 14 is coaxially fixedly connected to the second rotating shaft 20. A first rotating shaft 16 is rotatably connected to the bottom of the chassis 1. A driven bevel gear 15 that meshes with the driving bevel gear 14 is coaxially fixedly connected to the top of the first rotating shaft 16. A driving pulley 17 is also coaxially fixedly connected to the first rotating shaft 16. A driven pulley 22 is coaxially fixedly connected to the bottom of the third rotating shaft 24. The driving pulley 17 and the driven pulley 22 are driven and engaged by a transmission belt 18.

[0030] Since the drive mechanism and the third rotating shaft 24 are located in two different areas separated by a partition, a clearance hole 21 is needed in the partition for the transmission belt 18 to pass through. Both the driving pulley 17 and the driven pulley 22 used above can be synchronous pulleys, in which case the transmission belt 18 is a synchronous belt. The motor 13 mentioned above is equipped with a worm gear reducer, which allows the position of the limiting plate 35 to be locked when the motor 13 stops working.

[0031] As a further illustration of this example, since the slicing device requires material to be discharged from the front end, the front end of the chassis 1 is often open. However, a completely open cutter head 28 would also be exposed to contact, thus increasing the risk of accidental cuts. To avoid this risk, slide rails 4 are fixedly connected to both sides of the front end of the chassis 1, and a sliding plate 5 is slidably installed between the two slide rails 4 to block the cutter head 28. A support plate 6 is fixedly connected to the top of the sliding plate 5, and the support plate 6 overlaps with the top of the chassis 1.

[0032] When the slicing device is needed, simply insert the sliding plate 5 downwards along the slide rail 4. When maintenance is required on the slicing chamber 2, simply push the sliding plate 5 upwards to remove it. The presence of the sliding plate 5 not only reduces the occurrence of cuts, but also prevents slices from flying around during the cutting process. The sliding plate 5 can block the forward-flying slices and make them fall back into the discharge hopper 3.

[0033] As a further illustration of this example, to make the slicing process more stable, a downward-extending feed pipe 26 is provided at the bottom of the feed inlet 27, with the bottom of the feed pipe 26 located above the cutter head 28. Since the medicinal material needs to be pushed downwards during the slicing process, there is a risk of cuts if pushed by hand. Therefore, this slicing device is also equipped with a push block 7 that matches the feed pipe 26. A baffle is provided on the push block 7 to prevent it from falling onto the cutter head 28. The baffle is located at the top of the push block 7 and its size is larger than that of the feed inlet 27.

[0034] The slicing device is equipped with different types of feed inlets 27, and the feed pipe 26 corresponds to the feed inlet 27. Through different types, the device can meet the needs of medicinal materials of different sizes.

[0035] The operating principle of this device is as follows: First, when the cutter head 28 is stationary, the position of the cutter head 28 is adjusted by adjusting the knob 11 as needed to achieve a suitable slicing thickness. After the position of the cutter head 28 is adjusted, the motor 13 is started, and the appropriate feed port 27 is selected to push the medicinal material. During the pushing process, the bottom of the medicinal material contacts the limiting plate 35 and is then cut by the blade 31. The sliced ​​medicinal material falls into the inclined discharge hopper 3 through the feed hole 36 and then slides out through the discharge hopper 3, thus completing the slicing of the medicinal material.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
