Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a feeding mechanism for a traditional Chinese medicine granulation machine. Background Technology

[0002] In the production of traditional Chinese medicine (TCM), herbs need to be ground into powder and then made into pills or tablets. However, due to the poor flowability of powder, tablets are prone to cracking and large differences in tablet weight. Therefore, it is best to make TCM into granules before tableting. These uniform and fine granules ensure the quality of the tablets. Thus, granulation machines are needed in TCM production. Most existing TCM granulation machines are swing-type granulation machines with a material bucket placed at the bottom of the machine to collect the produced granules. To facilitate the transfer of the material bucket, a feeding mechanism is required.

[0003] For example, a feeding mechanism for a traditional Chinese medicine granulator, disclosed in Chinese Patent Publication No. CN221564413U, belongs to the field of traditional Chinese medicine production. It includes a base and a material hopper. A back plate is provided on the rear side of the upper surface of the base, and a granulator body is installed on the front side of the back plate. The granulator body is suspended above the base. A groove is provided on the upper surface of the base, and rotating shafts are evenly installed inside the groove through bearings. The rotating shafts extend beyond the upper surface of the base. The material hopper is placed on the surfaces of multiple rotating shafts. Handles are symmetrically provided on both sides of the outer surface of the material hopper. The top of the rotating shafts is open. Multiple rotatable rotating shafts are provided on the upper surface of the base. The material hopper is then placed on the rotating shaft surfaces. When the material hopper is pulled to move, the rotation of the rotating shafts can reduce friction, achieving a labor-saving effect and ensuring the stability of the material hopper when it is in a fixed position. When the material hopper is full, the limiting of the material hopper can be released externally, and then the material hopper can be pushed outward by the extrusion plate to realize feeding.

[0004] Some problems were found when using the existing feeding mechanism of the Chinese medicine granulator. First, although the material barrel is pushed outward by the extrusion plate during the transfer process, the material barrel needs to be pushed and separated for a lot of time. During this process, the granulator needs to be stopped temporarily, which affects the working efficiency of the granulator. Utility Model Content

[0005] The purpose of this invention is to provide a feeding mechanism for a traditional Chinese medicine granulator to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a traditional Chinese medicine granulator, comprising a base and a material hopper. A limiting groove is formed on the base, and a threaded screw is rotatably installed within the limiting groove. Two limiting sliders are slidably installed within the limiting groove, and each limiting slider has a threaded through hole that engages with the threaded screw. Two placement seats are slidably installed on the base, and a slot is formed below each placement seat. A locking protrusion is fixedly connected to each limiting slider, and the locking protrusion engages with the slot. A placement groove is formed on each placement seat, and the material hopper is placed within the placement groove.

[0007] Preferably, a drive motor is fixedly connected to one side of the base, and the output end of the drive motor is fixedly connected to a threaded screw.

[0008] Preferably, the base is symmetrically fixed with limiting slide rails, and the two limiting slide rails have limiting grooves on their separating surfaces.

[0009] Preferably, the placement seat has symmetrically formed slide rail connecting grooves on its underside, the slide rail connecting grooves cooperate with the limiting slide rails, and the placement seat has formed wheel grooves on its underside, in which rollers are rotatably installed.

[0010] Preferably, the mounting base has mounting grooves on both the front and back, a limit block is slidably installed in the mounting groove, fixing holes are provided on the inner walls of both sides of the mounting groove, and a pull-out groove is provided on the front of the mounting groove.

[0011] Preferably, a limiting groove is provided on the front of the limiting block near the two side edges, a return spring is fixedly connected in the limiting groove, a limiting pin is fixedly connected to the other end of the return spring, a shifting handle is fixedly connected to the limiting pin, and the limiting pin cooperates with the fixing hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By starting the drive motor to drive the screw to rotate, the rotation of the screw can move the placement seat and place the empty material bucket into another placement slot. During the synchronous lateral movement of the two placement seats, the material bucket that originally contained the pellets will move to the side, while the empty material bucket will move to below the discharge port of the pellet mill. At this time, the normal operation of the pellet mill can be restored, which can minimize the impact of conveying the material bucket on the normal production of the pellet mill.

[0014] 2. After the limiting pin is moved out of the fixing hole, the restriction on the mounting slot is released. At this time, the limiting block can be pulled out from the mounting slot using the pull-out slot to release the restriction on the placement seat. The placement seat can be directly removed for easy maintenance in the future, or the placement seat with a suitable diameter placement slot can be replaced. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a feeding mechanism for a traditional Chinese medicine granulator, including a base 1 and a material bucket 9. A limiting groove 101 is provided on the base 1. A threaded screw 102 is rotatably installed in the limiting groove 101. Two limiting sliders 3 are slidably installed in the limiting groove 101. A threaded through hole 301 is provided in the limiting slider 3. The threaded through hole 301 is threadedly engaged with the threaded screw 102. Two placement seats 4 are slidably installed on the base 1. A slot 401 is provided under the placement seat 4. A locking protrusion 302 is fixedly connected to the limiting slider 3. The locking protrusion 302 cooperates with the slot 401. A placement groove 404 is provided on the placement seat 4. The material bucket 9 is placed in the placement groove 404.

[0023] In this embodiment, by placing the material bucket 9 inside the placement slot 404, the threaded through hole 301 is threadedly engaged with the threaded screw 102, and the rotation of the threaded screw 102 can drive the two limiting sliders 3 to move. The locking protrusion 302 engages with the locking groove 401, and the movement of the two limiting sliders 3 can synchronously drive the two placement seats 4 to move. The empty material bucket 9 is placed in another placement slot 404. During the synchronous lateral movement of the two placement seats 4, the material bucket 9 that originally contained the pellets will move to the side, and the empty material bucket 9 will move to below the discharge port of the pellet mill. At this time, the normal operation of the pellet mill can be restored, and the material bucket 9 will be conveyed to one side. Further handling will not affect the normal operation of the pellet mill.

[0024] To avoid friction between the placement seat 4 and the base 1, the device employs the following technical solution: a drive motor 103 is fixedly connected to one side of the base 1, and the output end of the drive motor 103 is fixedly connected to the threaded screw 102. Limiting slide rails 2 are symmetrically fixed on the top of the base 1, and limiting grooves 201 are opened on the separating surfaces of the two limiting slide rails 2. Slide rail connecting grooves 403 are symmetrically opened on the bottom of the placement seat 4, and the slide rail connecting grooves 403 cooperate with the limiting slide rails 2. A wheel groove is opened on the bottom of the placement seat 4, and a roller 402 is rotatably installed in the wheel groove.

[0025] By starting the drive motor 103, the threaded screw 102 can be rotated. The rotation of the threaded screw 102 is used to drive the placement seat 4 to move. The roller 402 is used to support the placement seat 4, so that the placement seat 4 is in a rolling connection with the base 1, thereby avoiding the friction between the bottom of the placement seat 4 and the top of the base 1, and at the same time reducing the power required to drive the placement seat 4 to move.

[0026] To achieve the purpose of confining the placement seat 4 to the base 1, the device adopts the following technical solution: the placement seat 4 has mounting grooves 5 on both the front and back, and a limiting block 502 is slidably installed in the mounting groove 5. Fixing holes 501 are opened on the inner walls of both sides of the mounting groove 5. A pull-out groove 503 is opened on the front of the mounting groove 5. A limiting groove 6 is opened on the front of the limiting block 502 near the two side edges. A return spring 601 is fixedly connected in the limiting groove 6. A limiting pin 602 is fixedly connected to the other end of the return spring 601. A shifting handle 603 is fixedly connected to the limiting pin 602. The limiting pin 602 cooperates with the fixing hole 501.

[0027] The limiting block 502 is slidably installed inside the mounting groove 5. At this time, one end of the mounting groove 5 will be inserted into the limiting groove 201, restricting the limiting slide rail 2 from moving out of the slide rail connecting groove 403, and placing the placement seat 4 on the base 1. The return spring 601 can provide a certain pushing force to the limiting pin 602. The limiting pin 602 will be pushed into the fixing hole 501, thereby fixing the limiting block 502 inside the mounting groove 5. The shifting handle 603 can be used to drive the limiting pin 602 to move. After the limiting pin 602 is moved out of the fixing hole 501, the restriction on the mounting groove 5 is released. At this time, the limiting block 502 can be pulled out from the mounting groove 5 using the pull-out groove 503, releasing the restriction on the placement seat 4. The placement seat 4 can be directly disassembled for easy maintenance in the future, or the placement seat 4 with a suitable diameter placement groove 404 can be replaced.

[0028] The working principle and usage process of this utility model are as follows: During use, the material bucket 9 is placed inside the placement slot 404 to hold the Chinese medicine granules produced by the granulator. After the material bucket 9 is filled, the granulator is temporarily shut down, and the empty material bucket 9 is placed in another placement slot 404. The drive motor 103 is started to drive the threaded screw 102 to rotate. The rotation of the threaded screw 102 can drive the two limiting sliders 3 to move. The engaging protrusion 302 cooperates with the slot 401, and the movement of the two limiting sliders 3 can synchronously drive the two placement seats 4 to move. During the synchronous lateral movement of the two placement seats 4, the material bucket 9, which originally held the granules, will move to the side, while the empty material bucket 9 will move below the granulator's discharge port. At this point, the normal operation of the granulator can be resumed, completing the conveying action of the material bucket 9. The time spent filling the Chinese medicine granules can be used to move the material bucket 9.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
