Description

Technical Field

[0001] This utility model relates to a medicinal herb cutting machine, specifically a machine for cutting loosely shaped Chinese medicinal herbs. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are finished or semi-finished products made from raw medicinal materials through special processing and preparation according to the needs of dispensing or formulation under the guidance of TCM theory. They serve as basic raw materials for clinical dispensing and the production of TCM preparations, playing a crucial role in the therapeutic effects of TCM. The production process of TCM decoction pieces mainly includes three stages: cleaning, slicing, and processing. The slicing stage involves physically dividing the medicinal materials into specific shapes such as slices, segments, shreds, and blocks according to their pharmacological properties and natural growth characteristics, thus meeting the requirements of clinical dispensing and maximizing their pharmacological efficacy. Traditional methods of slicing Chinese medicinal herbs rely on experience and specialized tools, using manual or semi-mechanized methods depending on the different parts of the herb and their physical morphology. These methods are inefficient, labor-intensive, and lack precise control over the slicing shape and specifications, failing to meet the demands of modernizing traditional Chinese medicine. While mechanization in herb processing has improved significantly in recent years, with the public release of various cutting equipment, the technical solutions for these devices remain largely general-purpose, lacking specialized solutions tailored to specific morphological characteristics. Clearly, general-purpose equipment cannot simultaneously meet the processing requirements of herbs derived from roots, stems, leaves, flowers, and fruits, significantly limiting its application in actual production. This results in a lack of specialization and inconsistent application, hindering the improvement of slicing precision and processing quality. Therefore, it is necessary to conduct specialized research and development on herb processing equipment to address these existing technical problems. Utility Model Content

[0003] The purpose of this invention is to provide a cutting machine for loosely shaped Chinese medicinal materials, which is professionally applied to the cutting and processing of Chinese medicinal materials such as whole herbs, stems and branches, and leaves, thereby improving the cutting accuracy and the quality of processed medicinal materials.

[0004] A loose-form Chinese medicinal herb cutting machine includes: a frame, a blade holder, a clamping cover, conveying rollers, a cutting blade, a cutting blade seat, and a limiting block. The frame is a structural support fixedly mounted on the ground and has a transmission working surface arranged along a horizontal plane. The clamping cover is a tunnel-type cover installed on the upper part of the transmission working surface, and sequentially forms a first, second, and third bundled section along the transmission direction of the transmission working surface. The cross-sectional area of ​​the first and third bundled sections gradually decreases linearly along the transmission direction of the transmission working surface. This reduction in cross-sectional area helps to clamp the conveyed Chinese medicinal materials during transmission, increasing the agglomeration density of the materials. The lower part of the transmission working surface in the first and second bundled sections is respectively provided with regularly arranged, horizontally parallel conveying rollers. The conveying rollers are rotatably connected to the frame and can be driven to rotate at the same angular velocity. The upper end of the circumferential surface of the conveying rollers is respectively positioned on the transmission working surface... A rectangular window should be provided above the conveying working surface, allowing the rotation of the conveying roller to move and convey the Chinese herbal medicine material on the conveying working surface. The diameter of the conveying roller in the second clustering section is smaller than the diameter of the conveying roller in the first clustering section. This reduces the conveying speed of the Chinese herbal medicine material, achieving aggregation and compaction of the material in the second clustering section. The blade holder is fixedly mounted relative to the frame, and has a vertical guide shaft with a corresponding fixedly mounted limiting block. The cutter holder is slidably mounted on the blade holder with the vertical guide shaft and can be driven by power to reciprocate along the vertical guide shaft. The cutting blade is fixedly mounted on the cutting blade holder, forming a shearing structure with the front end of the conveying working surface. It can be driven by the cutting blade holder to achieve reciprocating shearing action. The limiting block correspondingly limits the downward stroke of the cutting blade holder, while simultaneously clamping the cutting blade on both sides to limit the elastic deformation that may occur during dynamic operation, ensuring the cutting accuracy of the Chinese herbal medicine material.

[0005] In the aforementioned loose-form Chinese herbal medicine cutting machine, a guide roller is preferably installed on the upper part of the tightening cover in the second bundle section to guide the transmission of the Chinese herbal medicine material, reduce transmission resistance, and avoid blockage accidents that may occur due to excessive bundle formation of the Chinese herbal medicine material in the second bundle section, which would affect the normal operation of production.

[0006] The loose-form Chinese herbal medicine cutting machine preferably has a shearing plate fixedly installed on the front end of the conveying working surface to increase the shearing mating surface between the front end of the conveying working surface and the cutting blade, thereby improving the shearing efficiency of the Chinese herbal medicine and further improving the cutting accuracy.

[0007] The loose-form Chinese herbal medicine cutting machine preferably has a limiting plate at the front end of the tightening cover. The limiting plate is connected and installed on the frame in an adjustable manner to adjust the distance L between the limiting plate and the shearing plate, thereby limiting the output cutting length of the Chinese herbal medicine and improving the cutting control accuracy of the Chinese herbal medicine.

[0008] The loose-form Chinese herbal medicine cutting machine preferably has inward curvature at both ends of the cutting blade, so that the cutting blade can dynamically gather the Chinese herbal medicine towards the center during the cutting process, which fully ensures that the cutting accuracy of the Chinese herbal medicine on the outer side is not affected by its position, and improves the uniformity of the cutting of the Chinese herbal medicine.

[0009] The loose-form Chinese medicinal material cutting machine further includes: a conveyor belt and a material collection box. The inner end of the conveyor belt is positioned at the lower part of the transmission working surface, and the outer end extends to the outer area of ​​the transmission working surface. The material collection box is positioned at the lower part of the outer end of the conveyor belt and can collect the finished material that has been cut on the transmission working surface and conveyed by the conveyor belt.

[0010] The beneficial effects of this utility model are that it provides a professional Chinese herbal medicine cutting machine, which is used to cut loose-form Chinese herbal medicines such as whole herbs, stems, and leaves. Through the structural cooperation between the clamping cover and the conveying roller, the Chinese herbal medicine material is clamped in three stages during the transmission process, gradually increasing the aggregation and density of the material, enhancing the cutting process of loose-form Chinese herbal medicines and the controllability of the cutting process. At the same time, by optimizing the structure of the cutting blade itself and its cooperation with the conveying working surface, the cutting accuracy of loose-form Chinese herbal medicines such as whole herbs, stems, and leaves is improved, and the processing quality of important medicinal slices is improved. When applied to actual production, it can also effectively reduce the labor intensity of workers and improve processing efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solution for which protection is sought in this utility model will be further described in conjunction with specific embodiments and accompanying drawings.

[0017] A machine for cutting loosely shaped Chinese medicinal herbs, such as Figures 1 to 4As shown, the machine is composed of a frame 1, a blade holder, a clamping cover 2, conveyor rollers 4, a cutting blade 5, a cutting blade seat 6, a limiting block 7, a guide roller 8, a limiting plate 9, a conveyor belt 12, and a material collection box 13. The frame 1 has a transmission working surface 10 arranged along a horizontal plane. The conveyor rollers 4, which are electrically synchronously controlled, are arranged horizontally and equally at the lower part of the transmission working surface 10 and are rotatably connected to the frame of the frame 1. Rectangular windows corresponding to the conveyor rollers 4 are opened on the transmission working surface 10. The upper ends of rollers 4 are respectively exposed above the rectangular windows on the upper part of the conveying working surface 10, keeping the vertices of the upper circumferential surfaces of the conveying rollers 4 on the same horizontal plane. The shearing plate 11 is connected and installed on the front end of the conveying working surface 10. The clamping cover 2 with a rectangular cross-section is installed on the conveying working surface 10, and along the conveying direction of the conveying working surface 10, it cooperates with the conveying working surface 10 to form a first bundle collection section 3a, a second bundle collection section 3b, and a third bundle collection section 3c in sequence. In the first bundle collection section 3a The first bundled section 3a and the second bundled section 3b are respectively provided with the conveying rollers 4. The guide rollers 8 are also installed on the upper part of the second bundled section 3b. Along the conveying direction of the conveying working surface 10, the height and width of the first bundled section 3a gradually decrease linearly. By reducing the cross-sectional area, the Chinese medicine materials conveyed in the first bundled section 3a are gradually bundled and tightened. The diameter of the conveying rollers 4 provided in the second bundled section 3b is smaller than the diameter of the conveying rollers 4 provided in the second bundled section 3b. By slowing down the conveying of the Chinese medicine materials in the first bundled section 3a, the conveying rollers 4 are gradually bundled and tightened. The conveying speed in the second bundle section 3b further concentrates and tightens the conveyed Chinese medicine material in the second bundle section 3b. Along the conveying direction of the conveying working surface 10, the height of the third bundle section 3c gradually decreases linearly. The reduction in cross-sectional area further concentrates and tightens the Chinese medicine material conveyed in the third bundle section 3c. The limiting plate 9 is provided at the front end of the tightening cover 2. The limiting plate 9 is movably and adjustablely connected to the frame 1, so that the distance L between the limiting plate 9 and the shearing plate is adjustable.The blade holder consists of two vertical guide shafts 14, limiting rods 15, and limiting blocks 7. The vertical guide shafts 14 are fixedly connected to the frame 1. The limiting rods 15 and the limiting blocks 7 are fixedly installed at the upper and lower ends of the vertical guide shafts 14, respectively. The two sides of the pneumatically controlled cutter holder 6 are slidably fitted onto the vertical guide shafts 14, allowing it to move vertically guided by the vertical guide shafts 14 and having its vertical travel limited by the limiting rods 15 and the limiting blocks 7. The cutting blade 5 is fixedly embedded in the cutter holder. In section 6, the blade faces downwards and has inward-curving ends, allowing it to cooperate with the shearing plate 11 fixedly mounted on the conveyor working surface 10 to form a shearing structure. A clamping structure is provided on the limiting block 7, which clamps and limits the cutting blade 5 from both sides, guiding it to maintain a vertical movement direction. The inner end of the conveyor belt 12 is positioned at the lower part of the conveyor working surface 10, and the outer end extends to the outer area of ​​the conveyor working surface 10. The material collection box 13 is correspondingly located at the lower part of the outer end of the conveyor belt 12.

[0018] When using the loose-form Chinese medicinal herb cutting machine to process Chinese medicinal herbs, firstly, the electric and pneumatic devices are turned on to drive the conveyor roller 4 and the cutter seat 6 to start working. The rotation speed of the conveyor roller 4 and the movement frequency of the cutter seat 6 are adjusted to a suitable state to meet the requirements of the cutting length of the Chinese medicinal herbs. Then, the Chinese medicinal material to be cut is placed on the conveying working surface 10. The rotating conveyor roller 4 can drive the Chinese medicinal material to move and convey on the conveying working surface 10 and continuously guide it into the clamping cover 3. In the first clamping section 3a, as the cross-section gradually decreases, the Chinese medicinal material achieves primary clamping. In the second clamping section 3b, as the conveying speed decreases, the amount of Chinese medicinal material increases, and the conveyed Chinese medicinal material achieves secondary clamping. In the third clamping section 3c, as the conveying power is removed and the cross-section is further reduced, the Chinese medicinal material can be further clamped. A three-stage tightening system is implemented. After the bundled Chinese medicinal materials are discharged from the outlet end of the tightening cover 3, the falling cutting blade 5 and the shearing plate 11 work together to cut and shear them. During the cutting process, the arc-shaped blade of the cutting blade 5 can first be drawn in from both ends of the bundled Chinese medicinal materials for cutting. It also has a dynamic tightening effect, which can prevent the bundled Chinese medicinal materials from loosening and scattering during the cutting process. Cutting can be carried out under good tightening conditions to ensure the quality of cutting. Through effective control of the processing, the discharge of Chinese medicinal materials from the tightening cover 3 and the falling of the cutting blade 5 alternate in a cycle, thereby realizing continuous operation and production. The cut Chinese medicinal materials fall naturally onto the conveyor belt 12 and can be automatically conveyed to the outer end by the conveyor belt 12 and collected by the material collection box 13. Then it can be transferred to the next process of Chinese medicinal decoction piece production. Under the above operating conditions, if there is a deviation in the matching degree between the rotation speed of the conveying roller 4 and the movement frequency of the cutter seat 6, or if the Chinese herbal medicine is unevenly discharged from the tightening cover 3, the limiting plate 9 will limit the amount of Chinese herbal medicine discharged from the tightening cover 3, thereby ensuring the mechanical operation and cutting accuracy.
