Description

Technical Field

[0001] The invention relates to the technical field of herb grinding, in particular to a raw material grinding device for herb processing. Background Art

[0002] Grinding of raw materials in herbal medicine processing is an important step in the preparation of traditional Chinese medicine. Its purpose is to increase the surface area of ​​the medicinal materials and improve the dissolution rate of the active ingredients, thereby enhancing the absorption and utilization efficiency of the drugs. This process is crucial to ensure the efficacy and quality of traditional Chinese medicine.

[0003] At present, the common methods of grinding herbal raw materials are mainly divided into two types: manual grinding and mechanical crushing. Among them, traditional tools, such as mortar and pestle, are usually used in manual grinding for reciprocating operations, so that the medicine can be crushed and crushed to achieve a powder effect. Although this method can ensure the fineness of grinding, it is inefficient and depends on the experience of the operator. Secondly, mechanical crushing uses modern mechanical equipment, such as shredders, to first shred the herbal raw materials to change the shape of the herbs, and then perform secondary processing as needed to achieve a finer grinding effect. This method is more efficient than manual grinding, but may require additional steps to achieve the ideal grinding effect, which increases the complexity of the work. Therefore, in view of the respective characteristics and limitations of manual grinding and mechanical crushing, it is particularly important to develop equipment that can combine the advantages of both.

[0037] Embodiment: A raw material grinding device for herbal medicine processing, such as Figure 1-Figure 5 As shown, including:

[0038] The frame 1 is a mounting carrier for various components, and the middle part of the frame is hollow;

[0039] There are two processing frames 2, which are symmetrically arranged on the top surface of the frame 1. A movable frame 21 is fixedly connected to the front and rear sides of the two processing frames 2. The bottom end of the movable frame 21 penetrates and slides on the top surface of the frame 1, so that the processing frame 2 can move up and down along the frame 1. A shredding assembly 22 for shredding medicines is arranged inside the processing frame 2. The shredding assembly 22 is composed of a driving member and a group of crushing rollers. The driving member drives the corresponding crushing rollers to rotate, so that the crushing rollers on both sides can rotate relatively to roll and shred the medicines to turn the medicines into tablets. This shredding technology is a prior art and will not be described here. A feeding frame 23 for discharging is connected to the bottom of the processing frame 2 to guide the shredded tablets to the next processing step.

[0040] A feeding frame 3 is connected between the tops of the two processing frames 2 and is used to transfer the medicine to be processed into the processing frame 2;

[0041] The grinding mechanism 4 is arranged on the frame 1 and is used for grinding the shredded medicine. The grinding mechanism 4 includes a base 41 arranged on the frame 1. Four grinding tables 42 extending left and right are arranged at intervals on the base 41. The grinding tables 42 are arc-shaped. The left and right ends of the grinding tables 42 are provided with material outlets for discharging materials. The material outlets are composed of arranged through holes, which can not only discharge the ground medicine, but also perform corresponding screening treatment on the medicine to ensure that large pieces of medicine will not be discharged from the material outlets. The left and right ends of the grinding table 42 are connected with a material guide frame 43 for receiving the medicine. The bottom end of the unloading frame 23 is tubular in number and layout consistent with the material guide frame 43 on the same side. The bottom end of the unloading frame 23 can be sleeved on the material guide frame 43 on the same side. On, the two are in a connected state. When the processing frame 2 moves up and down, while ensuring that the drug flow is closed and does not leak, the unloading frame 23 and the guiding frame 43 can form a matching sliding fit. An arc rod 44 is arranged between the two movable frames 21 on the left and right sides. The arc rod 44 and the movable frame 21 operate synchronously, and the protrusion of the arc rod 44 faces downward. A connecting frame 45 is slidably arranged between the two arc rods 44. A connecting shaft 46 passes through the bottom ends of the connecting frames 45. Grinding wheels 47 with the same number as the grinding tables 42 are arranged on the connecting shaft 46 for rotation at intervals. The grinding wheels 47 are attached to the corresponding grinding tables 42 to grind the drugs. When the drugs are continuously put into the grinding tables 42, the drugs will gradually increase or accumulate. In order to ensure that the grinding wheel 47 can operate normally, the grinding wheel 47 needs to be adjusted according to the height of the drug pile, and the movable frame 21 is moved up and down to adapt to the height change of the drug pile, so as to maintain the pressure of the contact between the grinding wheel 47 and the drug, ensure the smooth operation of the grinding wheel 47, and maintain close contact with the drug for grinding, thereby improving the adaptability and efficiency of the overall operation. A supporting frame 48 located between the two processing frames 2 is also provided on the top of the frame 1, and a swinging component for driving the grinding wheel 47 to swing is provided on the supporting frame 48.

[0042] like Figure 3 and Figure 5As shown, the swing assembly includes swing plates 49 rotatably arranged on the front and rear sides of the upper part of the carrier 48, and the bottom ends of the two swing plates 49 are provided with a straight groove, and the ends of the connecting shaft 46 are respectively embedded in the straight groove on the same side, so that the two form a sliding and rotating fit; a vertical guide groove 491 is also provided in the middle position of the swing plate 49, and a central axis is rotatably arranged in the middle of the carrier 48, and the front and rear ends of the central axis are connected to a circular plate 412, and the circular plate 412 is provided with a protruding rod on the side facing the adjacent swing plate 49, and the protruding rod is slidably penetrated in the guide groove 491 on the same side, and a servo motor 410 is also installed on the carrier 48, and the output shaft of the servo motor 410 A group of pulleys 411 are arranged between the central axis to enable the circular plate 412 to rotate. The convex rod on the circular plate 412 pushes the swing plate 49 along the guide groove 491, so that the swing plate 49 can swing left and right with the connection of the carrier frame 48 as the axis, and then pull the lower grinding wheel 47 and other components to operate synchronously. From then on, the grinding wheel 47 can grind circumferentially with the grinding table 42 as it swings, and the shredded tablets are crushed. Compared with the traditional division of labor processing, while ensuring the consistency of operation, it also provides more coherent and automated process processing under the premise of simple operation.

[0043] like Figure 1 , Figure 6-Figure 8 As shown, a toggle mechanism 5 for toggling the medicine is provided on the connecting shaft 46, and the toggle mechanism 5 includes a toggle ring 1 52 slidably arranged inside the left side of the four grinding tables 42, and a toggle ring 2 53 slidably arranged inside the right side of each grinding table 42. The toggle ring 1 52 and the toggle ring 2 53 are consistent in shape, but the two are symmetrically arranged left and right. An arc frame 51 is symmetrically arranged on the connecting shaft 46, and the left and right ends of the arc frame 51 are respectively connected to the adjacent toggle ring 1 52 and the toggle ring 2 53, and the two toggle rings 1 52 and the toggle ring 2 53 in the middle are both in a connected state, so that the toggle rings 1 52 and the toggle rings 53 on both sides are connected. The movable ring 2 53 forms an integrated structure, so as to cooperate with the operation of the connecting shaft 46 and the grinding wheel 47 to achieve synchronous swing, so as to utilize the arc surface of the toggle ring 1 52 or the toggle ring 2 53 to tilt the accumulated medicine out, ensuring that the medicine can be concentrated on the side of the grinding wheel 47, so that the distribution of the medicine can be more concentrated, thereby improving the grinding efficiency of the device, and there is a gap between the adjacent toggle rings 1 52 and 2 53 to provide space for the grinding of the grinding wheel 47, and in the initial state, the toggle ring 1 52 and the toggle ring 2 53 are respectively blocked on the material openings on both sides of the grinding table 42, and can open the material openings according to the swinging operation to discharge the medicine after grinding.

[0044] like Figure 1 and Fig. 9As shown, a lifting assembly 6 for assisting in lifting the grinding wheel 47 is provided on the circular plate 412, and the lifting assembly 6 includes trapezoidal plates 61 symmetrically arranged on the left and right sides of the circular plate 412, and a contact frame 62 that contacts and cooperates with the trapezoidal plate 61 on the same side is symmetrically arranged front and back between the two processing frames 2. When the circular plate 412 moves to the end, the grinding wheel 47 is close to the material port position, and the contact operation between the trapezoidal plate 61 and the contact frame 62 is utilized to push the processing frame 2 a certain distance, thereby driving the grinding wheel 47 to maintain a distance from the grinding table 42, so that the medicine can be discharged smoothly from the material port without being squeezed by the grinding wheel 47.

[0045] like Figure 1 and Fig.10 As shown, a dispersing mechanism 7 for dispersing drug feed is provided on the feeding frame 3, and the dispersing mechanism 7 includes two groups of right-angle plates 71 arranged at front and rear intervals on the upper part of the carrier 48, and the two right-angle plates 71 in the same group are arranged symmetrically on the left and right, and an inclined plate 72 is respectively arranged on the top of the right-angle plate 71, and a slot is opened on the inclined plate 72; two groups of inclined grooves are spaced apart on the left and right sides on the side wall of the feeding frame 3, and the inclined grooves in the same group are symmetrically arranged in the front and rear, and a partition frame 73 for dispersing drugs is slidably arranged between the two inclined grooves in the same group, and the ends of the partition frame 73 are respectively slidably inserted into the slots of the inclined plate 72 on the same side, and three plates are arranged at intervals from left to right on the partition frame 73, thereby presenting a frame with four compartments, so that the partition frame 73 can separate the drugs by utilizing the compartment combined sliding operation, so that the drugs can be evenly dispersed before entering the processing frame 2.

[0046] like Figure 1 , Fig.11 and Fig.12 As shown, a vibration mechanism 8 is provided on the grinding table 42, and the vibration mechanism 8 includes a pneumatic vibration hammer 81 which is symmetrically arranged between the two middle grinding tables 42, and a limit block 82 is also symmetrically arranged between the other two adjacent grinding tables 42. The piston of the pneumatic vibration hammer 81 is connected with a knocking rod 83 which is passed through the limit blocks 82 on the same side. The knocking rod 83 is used to impact the material port position of the grinding table 42, thereby increasing the speed of the drug discharge port and avoiding the accumulation and blockage of the drug. At the same time, it can also assist and promote the movement of the drug on the grinding table 42 by vibration.

[0047] like Fig.11 As shown, streamline plates 84 are also included. Streamline plates 84 for blocking drug splashing are set on the front and rear sides of the grinding table 42. The two streamline plates 84 on the same grinding table 42 are gathered together and approached to the center, so as to block the moving drug and prevent the drug from splashing or flying out.

[0048] When the medicine needs to be ground, the device can be used. First, the frame 1 is placed on a stable ground, and then the medicine to be processed is placed in the feeding frame 3, and the medicine immediately falls into the two processing frames 2 below. The medicine is broken by the shredding component 22 to form fragments. Then, the fragmented medicine is pushed by the shredding component 22 and falls into the unloading frame 23 below, and then flows into the guide frame 43, and finally enters the grinding table 42, and then the servo motor 410 is started, and the servo motor 410 is driven to rotate. The motor 410 drives the pulley group 411 to rotate, thereby driving the central axis that passes through the carrier 48 to rotate, so that the circular plates 412 at both ends of the central axis rotate synchronously, so that the protruding rods on the circular plates 412 move along the trajectory of the corresponding guide grooves 491, and pull the swing plates 49 on both sides, so that the swing plates 49 are pushed to swing around the connection point of the carrier 48 as the axis, thereby driving the connecting shaft 46 and the rolling wheel 47 at the bottom to swing synchronously, and the connecting frame 45 will also slide on the arc rod 44 with the swing, so that the rolling wheel 47 can be driven to rotate synchronously. The wheel 47 can grind and grind the medicine along the track of the grinding table 42. Due to the height difference formed by the arcs at both ends of the grinding table 42 and the influence of the accumulation of the added medicine, the grinding wheel 47 will be lifted to a certain extent in the process of fitting the grinding table 42, and the connecting shaft 46 will be pushed up in the slot of the swing plate 49, and then the connecting frame 45 will be pushed up, so that the connecting frame 45 will push the arc rod 44 and the corresponding moving frame 21 upward while sliding with the arc rod 44, so as to 2 is pushed to a certain extent, so that the processing frame 2 and the feeding frame 3 are subjected to a certain amplitude of ups and downs, and the partition frame 73 follows the upward movement and slides along the groove track of the inclined plate 72, and then the partition frame 73 is squeezed by the groove of the inclined plate 72, pushing the partition frame 73 to slide in the inclined groove on the feeding frame 3, so that the partition frames 73 on both sides move in opposite directions, thereby shaking and breaking up the drugs covered thereon, ensuring that the drugs can be separated when entering the feeding frame 3, so as to facilitate the subsequent tearing and grinding operations;

[0049] As the grinding wheel 47 keeps rolling, the arc frame 51 is driven to swing synchronously with it, and then the toggle rings 1 52 and 53 at both ends of the arc frame 51 operate synchronously, so that the toggle rings 1 52 and 53 keep moving left and right in contact with the grinding table 42; when the swing plate 49 swings to the left, the torn and fallen tablets first contact the toggle ring 1 52 after passing through the guide frame 43, and due to the left swing, the end of the toggle ring 1 52 moves to the high point on the left, and then the torn medicine is affected by gravity. The ring 52 is continuously attached to the track of the toggle ring 52 and is concentrated and tilted to one side of the grinding wheel 47. The medicine is gathered at the bottom end of the grinding wheel 47. The medicine is ground under the rotation and rolling of the grinding wheel 47. At the same time, the circular plate 412, the swing plate 49 and the toggle ring 52 swing to the leftmost end, and then the material opening on the grinding table 42 is opened, and the grinding wheel 47 also moves close to the material opening position. Then the trapezoidal plate 61 on one side of the circular plate 412 will contact the contact frame 62 and push the processing frame 2, so as to lift the grinding wheel 47 and make it out of contact with the material opening. The ground medicine powder can be discharged smoothly through the material port, and then the toggle ring 1 52 is pushed to the right and reset by the swing plate 49, and then the residual medicine on the grinding table 42 is scraped by the right end of the toggle ring 1 52, so that the medicine can move to the side of the grinding wheel 47 with the right movement, so that the grinding wheel 47 can keep in contact with the medicine to perform the grinding operation while complying with the operation, and at this time, the toggle ring 2 53 will move to the right with the reset operation of the toggle ring 1 52, so as to push and scrape the medicine on the right side. , and then the trapezoidal plate 61 on the other side will also cooperate with the contact frame 62, so that the ground medicine on the right side can be discharged through the right material port of the grinding table 42; in this process, the pneumatic vibration hammer 81 is started synchronously, and the pneumatic vibration hammer 81 drives the knocking rod 83 to move back and forth, so that the knocking rod 83 continuously moves on the limit block 82 and contacts with the material port position of the grinding table 42, knocking and vibrating the material port position, thereby intensifying the falling of the screened medicine, making the screening of the ground medicine powder more thorough, and ensuring that the discharge of the medicine powder can be smoother.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
