Description

Technical Field

[0001] The utility model relates to the field of Chinese herbal medicine processing equipment, in particular to a cutting device for rhizome Chinese herbal medicines. Background Art

[0002] At present, most of the Chinese herbal medicines are rhizome Chinese herbal medicines. When processing rhizome Chinese herbal medicines, cutting operations are often required. The purposes are, first, to facilitate processing and improve the quality of decoction, and second, to facilitate dispensing and storage, making it convenient for preparation and identification, and conducive to the extraction of active ingredients. At present, most Chinese herbal medicine cutting is carried out by machines. For example, a Chinese herbal medicine cutting device disclosed in patent CN114290392B is provided with a conveyor belt for conveying the Chinese herbal medicines. The driving mechanism drives the mounting frame to move up and down. During the up and down movement of the mounting frame, the conveyor belt is driven to move through the transmission structure. The conveyor belt can be pushed by the acting block and the feedback block. Each time the mounting frame moves up and down, that is, during the process of cutting once, the conveyor belt is fixed, realizing stable and uniform segmented cutting. When the cutter cuts on the conveyor belt in the above patent technology, it is very easy for the sections of rhizome Chinese herbal medicines to stick to each other. Therefore, during subsequent use, if this situation is found, manual picking and forced separation are still required, which seriously reduces the processing effect and efficiency and additionally increases the labor intensity of workers. Summary of the Utility Model

[0003] The existing cutting of rhizome Chinese herbal medicines is also mainly carried out by machines. The technology disclosed in the above patent technology is also cutting by machines, but it is easy to cause the sections of Chinese herbal medicines to stick to each other. Once the above situation occurs, manual picking and separation are still required, which not only reduces the cutting effect and efficiency, but also increases the labor intensity. At least one aspect or one purpose of this application can solve the above problems. Specifically, a cutting device for rhizome Chinese herbal medicines is designed, and the technical solution adopted is as follows:

[0004] A cutting device for rhizome Chinese herbal medicines, comprising:

The motor reducer is arranged on the support platform, and the other end of the rotating shaft of the cutter roller is connected to the support platform through a bearing.

[0009] Preferably, the cutter roller is of a hollow structure, and the cavity inside it extends to one end. The cutter roller is symmetrically provided with two mounting grooves penetrating through its circumferential wall. Each mounting groove is arranged along the axial direction of the cutter roller. The two mounting grooves extend to one end face of the cutter roller in the same direction and form open ends at this end. The cutter roller is detachably provided with a sealing plate at the open ends of the mounting grooves. The cutter disc is an annular cutter disc, which has a cutter seat on its inner circumferential side and cutter heads on its outer circumferential side. Each cutter seat of the cutter discs is provided with two sliding seats, and the two sliding seats are correspondingly slidably arranged in the two mounting grooves. A connecting piece is connected between the two sliding seats through the cutter roller, which can fix the sliding seats in the mounting grooves.

[0010] Preferably, the two sliding seats on each cutter seat are respectively provided with connecting holes, and the two connecting holes are symmetrically arranged with respect to the central axis of the cutter roller. A threaded connecting piece is penetrated between the two connecting holes, and the threaded connecting piece is connected with a nut.

[0011] Preferably, the threaded connecting piece is a screw rod, and the screw rod passes through the two connecting holes and is respectively connected with nuts at both ends.

[0012] Preferably, the end where the cavity of the cutter roller extends and the end where the mounting groove extends are the same end. The sealing plate has a clamping convex that can extend into the mounting groove, and the sealing plate is connected to the cutter roller through screws.

Specific embodiments

[0020] To clearly illustrate the technical features of this solution, the present utility model will be described in detail below through specific embodiments in combination with the drawings.

[0021] In addition, in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] As Figures 1-3 shown, a cutting device for rhizome Chinese medicinal materials includes a frame 1. A cutter roll 2 is rotatably provided on the frame 1. One end of the rotating shaft of the cutter roll 2 is connected to the motor reducer 3. A plurality of cutter heads 4 are vertically and detachably provided on the cutter roll 2. The plurality of cutter heads 4 are evenly spaced along the axial direction of the cutter roll 2, and the spacing distance is the length of the cut rhizome Chinese medicinal materials.

[0023] In addition to the above, it also includes a plurality of conveying mechanisms 5. The plurality of conveying mechanisms 5 are located below the cutter roll 2 and are evenly spaced along the axial direction of the cutter roll 2. The conveying direction is perpendicular to the axial direction of the cutter roll 2. The plurality of cutter heads 4 and the plurality of conveyor belts 501 are arranged alternately along the axial direction of the cutter roll 2, and each cutter head 4 can extend into the gap between two adjacent conveyor belts 501.

[0024] Place the rhizome Chinese medicinal materials on the conveying mechanism 5. The placement direction of the rhizome Chinese medicinal materials is generally parallel to the axial direction of the cutter roll 2. The conveying mechanism 5 continuously drives the rhizome Chinese medicinal materials close to the cutter roll 2. Finally, the rhizome Chinese medicinal materials are cut into multiple sections under the action of the cutter head 4. The cut Chinese medicinal materials are continuously conveyed to other places by the conveying mechanism 5. Since part of the cutter head 4 extends into the gap between two adjacent conveyor belts 501, therefore, the situation of adhesion between sections of the rhizome Chinese medicinal materials will not occur, and the Chinese medicinal materials can be completely cut, avoiding subsequent manual sorting and increasing labor.

[0025] Further, for the convenience of installation, especially to ensure the relative position between the cutter head 4 and the conveying mechanism 5 and to facilitate subsequent adjustment or addition of the number of cutter heads 4, a telescopic cylinder 6 is also provided between the cutter roller 2 and the frame 1. Two telescopic cylinders 6 are provided. One of the telescopic cylinders 6 is rotatably connected to one end of the rotating shaft of the cutter roller 2, and the telescopic rod end of the other telescopic cylinder 6 is connected to a support platform 7. The motor reducer 3 is arranged on the support platform 7, and the other end of the rotating shaft of the cutter roller 2 is connected to the support platform 7 through a bearing 8.

[0026] At the beginning of installing the cutter roller 2 and the conveying mechanism 5, first install the conveying mechanism 5 on the frame 1, then extend the telescopic rod of the telescopic cylinder 6, and then install the cutter roller 2 between the two telescopic cylinders 6. After installation, at this time, the cutter head 4 is just directly above the gap between two adjacent conveying mechanisms 5. Then retract the telescopic rod to partially insert the cutter head 4 into the gap between two adjacent conveying mechanisms 5, and the installation is completed.

[0027] Further, in order to be able to adjust the distance between the cutter heads 4 so as to change the cutting length, the cutter roller 2 is set in the following structural form, that is: the above-mentioned cutter roller 2 is a hollow structure, and its internal cavity 17 is similar in shape to the cutter roller 2 and is cylindrical. One end of the cavity 17 is closed, and the other end extends to the end of the cutter roller 2. The cutter roller 2 is symmetrically provided with two mounting grooves 9 penetrating through its circumferential wall (the so-called penetration means that the inner side of the mounting groove 9 extends to the cavity 17 and the outer side extends to the outer wall of the cutter roller 2). Each mounting groove 9 is arranged along the axial direction of the cutter roller 2, and the two mounting grooves 9 extend in the same direction to one end face of the cutter roller 2 and form an open end at this end. The cutter roller 2 is detachably provided with a plugging plate 10 at the open end of the mounting groove 9. The function of the plugging plate 10 is to connect the cutter roller 2 when no new cutter head 4 is added, increasing the strength of the cutter roller 2 (because the existence of the mounting groove 9 divides the cutter roller 2 into two discontinuous parts at this open end), and at the same time preventing the cutter roller 2 from having radial swing at this open section during rotation. The cutter head 4 is an annular cutter head 4, which has a tool holder 402 on its inner circumferential side and a cutting head 401 on its outer circumferential side. Two sliding seats 13 are provided on the tool holder 402 of each cutter head 4, and the two sliding seats 13 are correspondingly slidably arranged in the two mounting grooves 9. A connecting piece passes through the cutter roller 2 between the two sliding seats 13, enabling the sliding seats 13 to be fixed in the mounting grooves 9.

[0028] Further, two sliding seats 13 on each of the above cutter seats 402 are respectively provided with connecting holes 14. The two connecting holes 14 are symmetrically arranged with respect to the central axis of the cutter roller 2. A threaded connecting piece is passed through between the two connecting holes 14, and the threaded connecting piece is connected with a nut 16. This connection structure can fix the cutter head 4 while facilitating the movement of the cutter head 4, thereby facilitating the change of the distance between the cutter heads 4, and further changing the cutting length. When it is necessary to change the cutting length, loosen the nut 16, manually change the positions of the two sliding seats 13, so that the sliding seats 13 move along the installation groove 9, and then the cutter head 4 changes its position. When it reaches the desired position, tighten the nut 16 to fix the cutter head 4.

[0029] It should be understood that when the number of cutter heads 4 needs to be increased or decreased due to the change of position of the cutter head 4, the plugging plate 10 can be disassembled to make the cutter head 4 slide out of or penetrate into the installation groove 9, so as to reduce or increase the number of cutter heads 4. Further understanding is that when the distance between the above cutter heads 4 changes, the gap formed between the above conveying mechanisms 5 also needs to change accordingly, which is achieved by changing the width of the conveyor belt 501. In the extreme case, the conveyor belt 501 can be regarded as a very thin belt (approximate thin string). Of course, the above situation generally does not occur in this application. The general cutting length of this application is about 5 cm.

[0030] Further, in order to improve the firmness of the fixation of the cutter head 4, the above threaded connecting piece is a screw rod 15. The screw rod 15 passes through the two connecting holes 14 and is respectively connected with nuts 16 at both ends. By tightening the nuts 16 at both ends, the sliding phenomenon between the top of the bolt and the slider can be avoided, and the pre-tightening force can be further increased, and the firmness is better.

[0031] Further, the detachable connection between the above plugging plate 10 and the cutter roller 2 is specifically that one end of the cavity 17 of the cutter roller 2 extending is the same as one end of the installation groove 9 extending. The plugging plate 10 has a clamping convex 11 that can extend into the installation groove 9. The plugging plate 10 is connected to the cutter roller 2 by screws. The clamping convex 11 extending into the installation groove 9 can, on the one hand, improve the strength of the cutter roller 2, and on the other hand, the clamping convex 11 can play a role in ensuring the transmission ratio, that is, the side surface of the clamping convex 11 abuts against the side surface of the installation groove 9 to transmit power, avoiding the slipping phenomenon between the plugging plate 10 and the cutter roller 2.

[0032] Further, in order to more accurately adjust the distance between the cutter heads 4, a scale 12 is provided on the outer circumferential wall of the cutter roller 2 along its axial direction. Here, the scale 12 can be achieved by engraving, or can be drawn with a pen dipped in paint, etc.

[0033] Further, each of the above conveying mechanisms 5 includes a conveyor belt 501, a motor 502 and a pulley 503. The pulleys 503 of each conveying mechanism 5 are commonly connected to a rotating shaft, and one end of the rotating shaft is connected to the motor 502.

[0034] The above specific embodiments shall not be construed as limiting the scope of protection of the present utility model. For those skilled in the art of this technology, any alternative improvements or transformations made to the embodiments of the present utility model fall within the scope of protection of the present utility model.

[0035] Where the present utility model is not described in detail, it is common knowledge to those skilled in the art of this technology.
