Description

Technical Field

[0001] The utility model relates to a slicing device for conical Chinese medicinal materials, in particular to a longitudinal slicing device for conical Chinese medicinal materials. Background Art

[0002] Blind cutting is a cutting process in the post-printing process. Compared with the ordinary printing machine cutting that can only cut straight lines, blind cutting is mainly used to cut finished products with conical shapes. Blind cutting machines have been popularized in the printing process and have become a well-known processing technology.

[0003] In the processing technology of Chinese medicinal materials, the cutting method belongs to the traditional Chinese medicine processing method. Slicing is one of the Chinese medicine cutting methods. It is a processing technology process of cutting the washed and softened medicinal materials into slices by machine or manually according to different textures, hardness, individual sizes, thicknesses, etc. Most of the traditional slicing process cutting machines use ordinary horizontal cutting and oblique cutting processes. For the longitudinal cutting of conical Chinese medicinal materials such as aconite, the traditional method is to use manual fixed-station cutting. Manual placement and fixation require high action skills. The cutting blade is affected by gravity changes, making the cutting difficult and slow. To meet the needs of modern processing, after manually cutting off the head, bottom or making a horizontal cut in the middle to form a stable plane, it is manually placed and sent into the cutting machine for secondary cutting, and the risk for the pusher is high.

[0004] In the prior art, for conical Chinese medicinal materials such as the rhizomes or fruits of Chinese medicinal materials, with a diameter between 3 and 10 cm, such as aconite, bletilla striata, curcuma zedoaria, and tinospora capillipes, the existing blind cutting technology is only applicable to cutting materials with uniform sizes (after flowing water sorting), and there is no equipment more suitable for conical cutting. The traditional blind cutting machine is also not applicable to cutting conical Chinese medicinal materials with different sizes and shapes (such as aconite, bletilla striata, curcuma zedoaria, and tinospora capillipes). At the same time, the existing sorting and conveying structure after sorting cannot ensure the unified discharging and placement of conical Chinese medicinal materials. For the longitudinal cutting of Chinese medicinal materials, the conical Chinese medicinal materials with chaotic discharging and placement need to be manually straightened. Therefore, the processing technology usually adopts manual cutting, but this process is obviously labor-consuming, and the thickness of the cut finished products is inconsistent, making it difficult to achieve the required cutting results. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a novel cutting device for conical Chinese medicinal materials to solve the problems that traditional longitudinal cutting requires manual placement and blind cutting is not applicable to cutting conical medicinal materials.

[0006] To achieve the above object, the present utility model provides the following technical solution: A longitudinal cutting and slicing device for conical Chinese medicinal materials, comprising a spiral transmission structure and a steaming and cutting structure. The spiral transmission structure is a spiral-shaped downwardly rotating medicinal material conveying channel. The cutting device is provided with a plurality of spiral transmission structures. The spiral transmission structure is formed by splicing the left and right parts in half, and is divided into an inner ring track close to the spiral central axis and an outer ring track far from the spiral central axis. The dynamic friction coefficient between the inner ring track and the surface of the medicinal material is 0.2 to 0.5, and the dynamic friction coefficient between the outer ring track and the medicinal material is 0.07 to 0.12. The steaming and cutting structure is divided into a longitudinal cutting knife device and a mold device. The main structure of the mold device is a turntable. The center of the turntable structure is a rotating shaft structure. A plurality of receiving plates for Chinese medicinal materials are connected to the outer circumference of the turntable. The receiving plate is a hollow columnar and U-shaped steaming and cutting lower template. The inner bottom of the receiving plate is in the shape of a spherical arc A, and a pressure sensor device is connected to the outer bottom; The longitudinal cutting knife device is divided into left and right blade groups and a touch plate located between the left and right blade groups. The touch plate is a pressing and positioning device for the medicinal material to be cut. Blade group housings are provided on the left and right blade groups. Blade holes are provided on the blade group housings. The left and right blade groups are telescopic blade groups. The left and right blade groups are respectively composed of a plurality of blades.

[0007] Preferably, both the inner ring track and the outer ring track are multi-layer structures, which are composed of an outer hard shell, a middle soft elastic layer, and an inner mesh contact layer. The diameter of the inner mesh contact layer is smaller than the diameter of the medicinal material, and the diameter of the middle soft elastic layer is larger than the diameter of the medicinal material.

[0008] Compared with the prior art, the beneficial effects of the present utility model are: Compared with the existing manual cutting and semi-automatic cutting processes, the conical cutting device of the present utility model has higher efficiency and does not require manual operation, saving working hours.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] When a gyro rotates, it not only rotates around its own axis but also makes a conical motion around a vertical axis. That is to say, the gyro rotates "self-rotates" around its own axis and "revolves" around the vertical axis at the same time. The speed of the gyro's "self-rotation" around its own axis determines the size of the gyro's swing angle. The slower it rotates, the larger the swing angle and the worse the stability; the faster it rotates, the smaller the swing angle, and thus the better the stability. This is similar to the principle of people riding bicycles. The difference is that one is a linear motion and the other is a conical curve motion. When the gyro rotates at a high speed, under the action of a gravity couple, instead of tipping over along the direction of the couple, it makes a conical motion around the vertical axis of the fulcrum. This is the gyro principle. In the present utility model, taking aconite as an example, since the frictional forces on both sides of the conical medicinal material are different after entering the spiral transmission structure, the friction coefficient of the inner ring track is greater than that of the outer ring track, generating a centripetal force. Under the action of the centripetal force, it begins to rotate. The conical medicinal material is affected by gravity and centripetal force and begins to rotate like a gyro.

[0017] Furthermore, both the inner ring track and the outer ring track are multi-layer structures, composed of an outer hard shell, a middle soft elastic layer, and an inner mesh contact layer. The diameter of the inner mesh contact layer is smaller than the diameter of the medicinal material, and the diameter of the middle soft elastic layer is larger than the diameter of the medicinal material. After the medicinal material enters the spiral transmission structure, it does not flip in the transmission structure suspended in the air, but is tightly squeezed against the soft mesh contact layer and slowly flips downward in the spiral transmission structure under the action of gravity. The longitudinal cut section shape of the medicinal material is approximately an irregular triangle. Under the influence of centripetal force and gravity in the spiral transmission structure, the final flipping result of the medicinal material is to flip out with the large head downward and the pointed head upward, so as to facilitate cooperation with the longitudinal cutting knife for cutting.

[0018] Furthermore, in the present utility model, the working principle of the pressure sensor connected to the outer bottom of the receiving tray is a simple well-known principle, and its structural features can be referred to the platform scale in the market. It has at least two functions: the pressure change when the medicinal materials on the production line fall into the receiving tray serves as the command switch for the rotation of the turntable; after the touch plate presses against the Chinese medicinal materials, its pressure acts on the sensor at the bottom. When the pressure change reaches a predetermined value (such as a pressure of 20 Newtons), the touch plate stops descending, and the cutting length of the telescopic blade group is calculated according to the different descending heights. The function of the blade group housing is to peel off the Chinese medicinal materials attached to the blade group when the blades contract.

[0019] Multiple receiving trays can be provided on the same turntable, and correspondingly, multiple sets of longitudinal cutting knife devices can be provided. Then, further, after the receiving tray reaches the predetermined position, the turntable can be disengaged from the connecting column on the receiving tray, and a certain amount of change occurs in the vertical height between the longitudinal cutting knife device and the receiving tray to facilitate the passage of the next receiving tray. After completing the cutting and dumping work, it resets and waits for an empty turntable to connect and take it away to achieve the production purpose of high-speed assembly line operation.
