Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine processing equipment technology, specifically to a device for precise slicing of traditional Chinese medicine decoction pieces with adjustable thickness. Background Technology

[0002] As one of the core forms of clinical medication in Traditional Chinese Medicine (TCM), prepared slices of Chinese medicinal herbs are sliced ​​products made from raw medicinal materials according to TCM theory and following traditional processing standards. The thickness of the slices is a key process parameter affecting efficacy. Slices of uniform thickness that meet processing standards ensure the even dissolution of active ingredients during decoction and other subsequent processing steps. This avoids problems such as excessive thickness hindering the extraction of active ingredients, or excessive thinness leading to loss of active ingredients and brittleness, thus ensuring the accuracy of TCM prescriptions and the stability of therapeutic effects. Currently, the production of Chinese herbal medicine slices mainly relies on traditional tools, primarily manual slicing knives and simple mechanical slicing devices, which have significant technical shortcomings. On the one hand, traditional tools lack a stable mechanism for fixing the medicinal materials, making them prone to displacement and slippage during slicing. This not only increases the difficulty of operation but can also lead to irregular slice shapes and edge damage, affecting the appearance and uniformity of the slices. On the other hand, adjusting the slice thickness using traditional tools depends on the operator's experience and judgment, lacking precise quantitative control methods. This makes it difficult to achieve accurate thickness settings for different medicinal materials and processing requirements, often resulting in significant deviations in slice thickness, failing to meet the standardization and regulation requirements of modern Chinese medicine production. With the modernization of the traditional Chinese medicine (TCM) industry, clinical practice demands higher standards for the consistency of quality and the stability of efficacy of processed TCM herbs. The limitations of traditional slicing tools have become a significant factor restricting the upgrading of the TCM processed herb industry. Therefore, developing a convenient, stable, and precisely controllable TCM processed herb slicing device is of great practical significance and application value for improving the production efficiency and quality of TCM processed herbs and promoting the standardization process of TCM. This is a technical need that urgently needs to be addressed in the field of TCM processing equipment. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the above-mentioned background technology by proposing a precision slicing device for Chinese herbal medicine slices with adjustable thickness. This device can simply and stably fix the Chinese herbal medicine material to be sliced, and precisely control the distance of each material push by adjustment, thereby adjusting the slice thickness and ensuring the consistency of the slice thickness each time.

[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A precision slicing device for Chinese herbal medicine slices with adjustable thickness includes a conveying platform, a cutting mechanism, and an adjustable material conveying mechanism. The conveying platform includes a conveying table, a cutting end seat, and a cutting end fixing mechanism, with the cutting end seat located at one end of the conveying table. The cutting mechanism includes a rotating shaft seat and a cutting tool. The rotating shaft seat is fixedly disposed on the rear side of the conveying platform. The cutting tool includes a blade, a rotating blade holder, and a handle. The rotating blade holder is connected to the rotating shaft seat via a rotating shaft.

The linear stepper motor is equipped with a slider. The conveying table is provided with a track groove. The base plate is slidably engaged with the track groove, and the base plate is fixedly connected to the slider.

[0006] Preferably, the conveyor table is configured as an arc-shaped concave surface, and the surface of the conveyor table is provided with a plurality of parallel convex strip structures, wherein the convex strip structures are straight lines parallel to the axis of the conveyor table.

[0007] Preferably, the cutting end fixing mechanism includes at least one tightening cable, a push-pull seat, a limiting structure, and a second driving device. The conveying table surface has a through hole extending into the interior of the conveying table. The push-pull seat, the limiting structure, and the second driving device are built into the conveying table. The two ends of the tightening cable pass through a through hole and are fixedly connected to the push-pull seat. The tightening cable forms a loop structure on the conveying table surface. The push-pull seat is slidably disposed in the conveying table through the limiting structure. The second driving device is connected to the push-pull seat to control the movement of the push-pull seat. By controlling the push-pull seat to move back and forth, the tightening and loosening of the tightening cable can be controlled.

[0008] Preferably, the limiting structure includes at least one limiting post, which is vertically fixed inside the conveying platform, and the push-pull seat is slidably sleeved on the limiting post; the second driving device includes a servo motor and a threaded screw, the threaded screw is fixedly connected to the rotating shaft of the servo motor, and the push-pull seat is threadedly connected to the threaded screw.

[0009] Preferably, a trigger control mechanism is also provided, which includes a linkage part and a trigger part. The linkage part includes a rotating body and a contact rod. A synchronous rotating shaft is provided in the rotating shaft seat, which simultaneously and fixedly connects the rotating body and the rotating tool holder. The contact rod is fixedly connected to the side of the rotating body. The trigger part includes a carrier and a pressure switch. The carrier is located on the side of the rotating body, and the pressure switch is disposed on the carrier. The rotating body drives the contact rod to swing to contact and disengage from the pressure switch. The pressure switch is coupled to the first driver and the second driver device through a control circuit module.

[0010] Preferably, the conveyor platform is provided with an operation control board, which is provided with an on / off switch, a display screen and an adjustment button for setting the single travel distance of the first driving device.

[0011] Preferably, the conveying platform further includes a base, which includes a main body and an extended placement plate. The extended placement plate is located below the cutting end seat and is equipped with a collection tray, which is detachably mounted on the extended placement plate.

[0012] Preferably, the conveyor table is configured as an arc-shaped concave surface, and the surface of the conveyor table is provided with a plurality of parallel convex strip structures, the convex strip structures being straight structures parallel to the axis of the conveyor table; the base plate is an arc-shaped plate structure adapted to the conveyor table, the lower surface of the base plate is provided with an interlocking protrusion, the interlocking protrusion being embedded in the groove formed by adjacent convex strip structures, and the upper surface of the base plate is provided with an anti-slip pad.

[0013] Preferably, the arc-shaped pressure plate is configured to have a variety of different specifications, with different lengths and curvatures, and the arc-shaped pressure plate and the slide rod can be detachably connected.

[0014] Compared with existing technologies, the adjustable thickness precision slicing device for Chinese herbal medicine slices, which adopts the above technical solution, has the following beneficial effects: 1. The material fixing frame can constrain and fix the rear end of the sliced ​​Chinese medicinal material. When the material fixing frame moves, it moves the medicinal material synchronously, effectively preventing rotation and tilting of the material, thus avoiding uneven slice thickness caused by deviation of the cut end. The first driving mechanism for the material fixing frame uses a linear stepper motor, which can precisely adjust the travel distance each time. Combined with the cutting end fixing mechanism, after each fixed travel distance, the cut end of the medicinal material is fixed to ensure stability during the cutting process and consistent slice thickness.

[0015] II. In the preferred embodiment of the cutting end fixing mechanism, a tightening cable is used to form a tightenable ring structure above the conveyor table. Through the second driving device (servo motor with screw screw), the push-pull seat can be controlled to move up and down quickly, so that the tightening cable can be quickly tightened and fixed on the Chinese medicine material. This fixing method using a tightening cable with flexibility or elasticity has the advantage of better conforming to various irregular materials and has a good fixing effect on materials of various sizes and shapes.

[0016] 3. During the cutting operation, the rotating blade holder drives the rotating body to rotate synchronously. When the rotating body rotates to a certain angle, its contact rod contacts and presses the pressure switch, thus achieving the effect of automatically controlling the first and second driving components according to the cutting action. After each cutting action, the cutting blade is raised until the contact rod contacts and presses the pressure switch. At this time, the fixation of the medicinal material to be cut is released, and the material fixing frame moves the medicinal material a fixed distance in preparation for the next cut. When the cutting blade is lowered to prepare for cutting, the contact rod disengages from the pressure switch, thus fixing the medicinal material to be cut. This cycle is repeated to continuously cut slices of equal thickness. Attached Figure Description
