Description

Technical Field

[0001] The invention belongs to the field of Chinese medicinal material processing and relates to a clamping mechanism of a Chinese medicinal material asparagus cochinchinensis core-removing machine. Background Art

[0002] In the field of traditional Chinese medicine processing, especially for spindle-shaped or cylindrical herbs such as asparagus cochinchinensis, coring has always been a key step in the processing. However, this process has long relied on manual labor, including kneading, cutting, and coring. This is not only labor-intensive but also inefficient, seriously restricting the development of the traditional Chinese medicine industry.

[0003] Limitations of traditional processing methods:

[0004] High labor intensity: Manual coring requires operators to perform repetitive labor for a long time, which can easily lead to fatigue and affect work efficiency and processing quality.

[0005] Low efficiency: The core removal time for a single Chinese medicinal material such as asparagus is long, usually between 30 and 60 seconds. This will significantly increase the overall processing time and reduce production efficiency when processing a large number of medicinal materials.

[0006] Unstable quality: Manual operations are greatly affected by human factors. The skill level, proficiency and fatigue level of different operators will affect the quality of core removal, resulting in uneven quality of processed medicinal materials.

[0007] High costs: With rising labor costs, the cost of core removal of traditional Chinese medicines, which relies on a large amount of manual labor, has also increased accordingly, posing a challenge to the profitability of enterprises.

[0008] The need for mechanized processing: Faced with the limitations of traditional processing methods, the Chinese herbal medicine processing industry urgently needs to introduce mechanized and automated processing equipment to improve processing efficiency, ensure processing quality, and reduce production costs. In particular, the core removal process requires the implementation of mechanized clamping and positioning technology, which is crucial.

[0009] Deficiencies in existing technologies: Although some mechanized processing equipment already exists in the field of agricultural product processing, the existing clamping and positioning technologies for the core removal of Chinese medicinal materials, especially spindle-shaped or cylindrical ones, still have obvious deficiencies. Specifically,

[0010] Unstable clamping: Existing clamping mechanisms are often difficult to adapt to Chinese medicinal materials of different sizes and shapes, resulting in unstable clamping. It is easy for the medicinal materials to slip during processing or be damaged by clamping too tightly.

[0011] Inaccurate positioning: Due to the lack of effective positioning technology, it is difficult to precisely control the position of Chinese herbal medicines during the processing, which directly affects the accuracy of core removal and the processing quality.

[0012] Poor adaptability: Existing clamping mechanisms can often only process Chinese herbal medicines of specific sizes or shapes, and it is difficult to meet the processing requirements of various Chinese herbal medicines, restricting their application scope.

[0013] Urgent needs for industry development:

[0014] Therefore, developing a clamping mechanism that can stably clamp, accurately position, and meet the core removal processing requirements of various Chinese herbal medicines has become an urgent need for the development of the Chinese herbal medicine processing industry. Such a clamping mechanism can not only significantly improve the efficiency and quality of core removal processing of Chinese herbal medicines, but also reduce processing costs and promote the mechanization and automation processes of the Chinese herbal medicine processing industry. At the same time, the application of this clamping mechanism will also help fill the gap in positioning technology in the field of mechanical processing of spindle-shaped or cylindrical crops, opening up new paths for the technological upgrading and development of related industries. Summary of the invention

[0015] In view of this, the purpose of the present invention is to provide a clamping mechanism for a Chinese herbal medicine asparagus core removal machine to solve the above existing problems.

[0016] To achieve the above purpose, the present invention provides the following technical solution: The clamping mechanism of the Chinese herbal medicine asparagus core removal machine includes an upper clamping plate positioning disk, a lower clamping plate positioning disk, six clamping plates, a clamping plate limiting disk, and a driving limiting rod; six rotating shafts evenly distributed along the circumferential direction are provided on the lower clamping plate positioning disk, and through holes for cooperating with the rotating shafts are respectively provided on the top and bottom surfaces of the six clamping plates near the rotating shafts. Six through holes matching the six rotating shafts are provided on the upper clamping plate positioning disk along the circumferential direction. The rotating shafts sequentially pass through the through holes of the clamping plates and the through holes of the upper clamping plate positioning disk to form the overall framework of the clamping mechanism; the clamping plate limiting disk is rotatably embedded in the center of the upper clamping plate positioning disk, and six oval slot holes are provided on its surface. Cylindrical keys matching the six oval slot holes are respectively provided on the tops of the six clamping plates, and the cylindrical keys form a sliding fit in the oval slot holes; the driving limiting rod is fixed on the upper surface of the clamping plate limiting disk and is used to drive the clamping plate limiting disk to rotate around the central axis; when the driving limiting rod rotates, relative sliding occurs between the oval slot holes of the clamping plate limiting disk and the cylindrical keys of the clamping plates, driving the six clamping plates to synchronously rotate around the rotating shafts of the lower clamping plate positioning disk, thereby reducing the clamping space and realizing the clamping and positioning of cylindrical or spindle-shaped Chinese herbal medicines.

[0017] Optionally, the cooperation mode between the through holes of the upper clamping plate positioning disk and the lower clamping plate positioning disk and the rotating shafts is clearance fit. Through the positioning of the upper clamping plate positioning disk and the lower clamping plate positioning disk, the six clamping plates only retain the freedom of rotation around the Z axis.

[0018] Optionally, the six clamping plates have exactly the same overall shape and size, and at least two of the clamping plates are provided with shielding plates at the bottom.

[0019] Optionally, the shape of the shielding plate is the major arc part remaining after circular chord cutting, which is used to prevent Chinese medicinal materials from falling off during the clamping process.

[0020] Optionally, the arc length of the major arc part of the shielding plate matches the circumferential diameter of the shaft distribution of the lower positioning disc of the clamping plate, ensuring that the shielding plate effectively covers the bottom of the medicinal materials during the clamping process.

[0021] Optionally, the driving limit rod drives the clamping plate limit disc to rotate through manual or mechanical driving, and its rotation angle range is from 0° to 90°, corresponding to the maximum opening state to the minimum clamping state of the clamping space.

[0022] Optionally, the clamping surfaces of the six clamping plates are arc-shaped or flat structures, and in the state of the minimum clamping space, the inner edges of the six clamping plates jointly form a regular hexagon contour circumscribing the maximum cross-section of the Chinese medicinal materials.

[0023] Optionally, the dimension of the long axis direction of the elliptical slot of the clamping plate limit disc is larger than the diameter of the cylindrical key of the clamping plate. When the clamping plate limit disc rotates, the change of the clamping space of the six clamping plates is driven through the sliding fit of the slot and the key.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1) Realize mechanized clamping and positioning: The clamping mechanism realizes stable clamping and precise positioning of Chinese medicinal materials (such as Asparagus cochinchinensis) through a mechanical structure, filling the gap in the positioning technology in the field of mechanical processing of spindle-shaped or cylindrical crops, and promoting the mechanization and automation process of Chinese medicinal material processing.

[0026] 2) Improve processing efficiency: Compared with the traditional manual core-removing method, the clamping mechanism can significantly shorten the core-removing time of a single Chinese medicinal material, thereby improving the overall processing efficiency. For example, it takes 30 to 60 seconds to manually remove the core of a single Asparagus cochinchinensis, while mechanized processing can greatly reduce this time.

[0027] 3) Ensure processing quality: The clamping mechanism ensures the stable position of Chinese medicinal materials during the processing through precise clamping and positioning, thereby improving the accuracy of core-removing and processing quality. This helps to reduce the damage of medicinal materials and the defective rate during the processing, and improves the overall quality of the product.

[0028] 4) Reduce labor intensity and cost: Mechanized processing reduces the dependence on manual labor, reduces the labor intensity, and also helps to reduce the fluctuation of processing quality caused by human factors. In addition, in the long run, mechanized processing can reduce the labor cost of enterprises and improve economic benefits.

[0029] 5) Enhanced adaptability: The clamping mechanism is designed with an adjustable clamping space, which can adapt to the processing requirements of Chinese medicinal materials of different sizes and shapes. This adaptability enables the mechanism to be not only applicable to the core-removing processing of specific Chinese medicinal materials such as asparagus, but also extended to the processing of other Chinese medicinal materials with similar shape characteristics.

[0030] 6) Improved safety: Mechanized processing reduces the chance of direct human contact with Chinese medicinal materials and lowers the risk of safety accidents caused by improper operation. At the same time, the stable clamping of the clamping mechanism also avoids the accidental slipping or splashing of the medicinal materials during processing, ensuring the safety of the operators.

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0042] Please refer to Figures 1 to 5 , which is the clamping mechanism of the machine for removing the cores of Chinese medicinal material asparagus roots, mainly composed of an upper positioning plate 1 of the clamping plate, a lower positioning plate 2 of the clamping plate, a first clamping plate 31, a second clamping plate 32, a third clamping plate 33, a fourth clamping plate 34, a fifth clamping plate 35, a sixth clamping plate 36, a clamping plate limiting disc 4 and a driving limiting rod 5.

[0043] The upper positioning plate 1 of the clamping plate: is provided with six through holes evenly distributed in the circumferential direction, corresponding one by one to the six rotating shafts on the lower positioning plate 2 of the clamping plate.

[0044] The lower positioning plate 2 of the clamping plate: contains six rotating shafts evenly distributed in the circumferential direction. These rotating shafts pass through the through holes of the six clamping plates and the through holes of the upper positioning plate 1 of the clamping plate in sequence to form the overall framework of the clamping mechanism.

[0045] Six clamping plates (the first clamping plate 31, the second clamping plate 32, the third clamping plate 33, the fourth clamping plate 34, the fifth clamping plate 35, the sixth clamping plate 36): Through holes for cooperating with the rotating shaft are respectively arranged on the top and bottom surfaces of each clamping plate close to the rotating shaft side. The overall shapes and sizes of the six clamping plates are exactly the same, and at least two of the clamping plates, such as the bottom of the second clamping plate 32 and the fifth clamping plate 35, are provided with a second clamping plate shielding plate 321 and a fifth clamping plate shielding plate 351. The shape of the shielding plate is the major arc part remaining after circular chord cutting, which is used to prevent Chinese herbal medicines from falling off during the clamping process.

[0046] Clamping plate limiting disc 4: Rotatably embedded in the center of the positioning disc 1 on the clamping plate, and six oval slots are opened on its surface. Cylindrical keys are respectively arranged on the tops of the six clamping plates and are in sliding fit with the six oval slots.

[0047] Driving limiting rod 5: Fixed on the upper surface of the clamping plate limiting disc 4 and used to drive the clamping plate limiting disc 4 to rotate around the central axis. When the driving limiting rod 5 rotates, the oval slots of the clamping plate limiting disc 4 and the cylindrical keys of the clamping plate produce relative sliding, driving the six clamping plates to rotate synchronously around the rotating shaft of the lower positioning disc 2 of the clamping plate, thereby reducing the clamping space and realizing the clamping and positioning of cylindrical or spindle-shaped Chinese herbal medicines.

[0048] Example 1,

[0049] Figure 2 : Schematic diagram of the maximum space clamped by the clamping mechanism

[0050] As Figure 2 shown, when the driving limiting rod 5 is in the initial position, the major axis direction of the oval slot of the clamping plate limiting disc 4 is consistent with the direction of the cylindrical key of the clamping plate, and the clamping space formed by the six clamping plates is the largest. At this time, the Chinese herbal medicine can be conveniently placed into the clamping space.

[0051] Example 2,

[0052] Figure 3 : Schematic diagram of the minimum space clamped by the clamping mechanism

[0053] As Figure 3 shown, when the driving limiting rod 5 rotates to the limit position (such as 90°), the minor axis direction of the oval slot of the clamping plate limiting disc 4 is consistent with the direction of the cylindrical key of the clamping plate, and the clamping space formed by the six clamping plates is the smallest. At this time, the Chinese herbal medicine is tightly clamped between the six clamping plates, realizing stable clamping and positioning.

[0054] Example 3,

[0055] Figure 4 : Schematic simulation diagram of clamping cylindrical or spindle-shaped Chinese herbal medicines represented by asparagus root

[0056] AsFigure 4 As shown in the figure, taking asparagus as an example, after placing the asparagus in the clamping space, by driving the rotation of the limit rod 5, the six clamping plates gradually approach and clamp the asparagus. During the clamping process, the asparagus is subjected to the combined action of the six clamping plates, and its center of gravity coincides with the central axis of the clamping mechanism, achieving precise positioning.

[0057] Example 4

[0058] Figure 5 : Schematic diagram of the second clamping plate baffle and the fifth clamping plate baffle of the clamping mechanism

[0059] As Figure 5 shown, at the bottom of the second clamping plate 32 and the fifth clamping plate 35, there are a second clamping plate baffle 321 and a fifth clamping plate baffle 351. The shape of the baffle is the major arc part remaining after circular chord cutting. During the clamping process, the baffle can effectively prevent the Chinese herbal medicine from slipping off from the bottom, improving the stability of clamping.

[0060] The present invention is used for asparagus core-removing processing, and its working principle includes the following steps:

[0061] Preparation stage: Put the asparagus Chinese herbal medicine to be core-removed into the clamping space of the clamping mechanism ( Figure 2 state).

[0062] Clamping stage: Rotate the driving limit rod 5 manually or mechanically to make the clamping plate limiting disc 4 rotate, and the six clamping plates gradually approach and clamp the asparagus Chinese herbal medicine Figure 3 state.

[0063] Core-removing stage: After the asparagus Chinese herbal medicine is stably clamped and positioned, use a core-removing tool to perform core-removing processing on the Chinese herbal medicine.

[0064] Discharging stage: After the core-removing processing is completed, rotate the driving limit rod 5 in the reverse direction to make the six clamping plates gradually move away, release the asparagus Chinese herbal medicine, and complete the core-removing processing process.

[0065] It can be seen from the above embodiments that the clamping mechanism of the asparagus core-removing machine for Chinese herbal medicine of the present invention can achieve stable clamping and precise positioning of spindle-shaped or cylindrical Chinese herbal medicines such as asparagus, providing strong support for the mechanization and automation of Chinese herbal medicine core-removing processing.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
