Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine processing technology, and in particular to a traditional Chinese medicine kneading machine. Background Technology

[0002] During the drying process, the skin and flesh of medicinal herbs easily separate, making the herbs loose and bubbly. Frequent kneading during drying helps to tighten the skin and flesh, achieving a moist, plump, soft, or translucent texture, as seen in herbs like Polygonatum odoratum, Codonopsis pilosula, and Panax notoginseng. Similarly, with Astragalus membranaceus, kneading breaks down the rhizome, increasing the herb's flexibility and making it easier to extract its medicinal value. Existing herbal medicine kneading machines typically utilize two or more kneading rollers to rotate and knead the medicinal herbs at the bottom of the rollers. For example, Chinese patent document CN215611861U discloses a herbal medicine kneading machine in which the motor is fixed in the middle of the horizontal front end of the lower layer of the frame. The motor shaft is connected to the drive shaft via a pulley. The drive sprocket of the lower roller is connected to the driven sprocket of the lower roller on the right end of the lower roller shaft via a belt. The drive guide gear meshes with the driven guide gear on the driven shaft located above the drive shaft in the longitudinal middle of the front side of the frame. The drive sprocket of the upper roller located on the right end of the driven shaft is connected to the main sprocket of the upper roller shaft via a chain. The upper and lower rollers rotate relative to each other, and the medicinal herbs can be effectively kneaded as they pass through the middle without damaging their internal structure. However, in this method, the medicinal materials mainly move laterally from the inlet to the outlet, and are mainly concentrated at the bottom of the equipment. This results in some medicinal materials not being fully kneaded, and the medicinal materials between two adjacent kneading rollers and between the outer diameter of the kneading roller and the kneading barrel are not kneaded, resulting in uneven kneading.

[0003] Therefore, in view of the problems existing in the prior art, there is an urgent need to provide a kneading technique for Chinese medicinal materials that can knead thoroughly, evenly and efficiently. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a Chinese herbal medicine kneading machine that can knead thoroughly and evenly and with high efficiency.

[0015] Preferably, the drive unit includes a motor, a drive shaft, a first bevel gear, a second bevel gear, a rotating shaft, a connector, a connecting rod, a hinge arm, and a hinge support assembly.

[0016] The motor drives the transmission shaft to rotate. The transmission shaft is equipped with a first bevel gear and a second bevel gear is installed on the rotating shaft. The first and second bevel gears mesh and drive each other. The lower end of the rotating shaft is fixedly connected to the inner kneading wheel.

[0017] The rotating shaft is fixedly connected to a connector. The upper end of the connecting vertical rod is installed on the connector. The lower end of the connecting vertical rod is connected to the convex arm of the kneading outer cylinder and hinged to one end of the hinge arm. The other end of the hinge arm is hinged to the hinge support assembly.

[0018] Preferably, the kneading outer cylinder has two or more protruding arms, and the number of connecting vertical rods, hinge arms and hinge support components is the same as the number of protruding arms. One protruding arm, one connecting vertical rod, one hinge arm and a set of hinge support components together constitute a hinge unit.

[0019] The hinged support assembly is located on the outside of the kneading disc.

[0020] Preferably, the articulated support assembly includes a leg, a bearing, and a pin, with the pin passing through the articulated arm and rotatably mounted to the leg via the bearing.

[0021] Beneficial effects of the invention:

[0022] The herbal medicine kneading machine of the present invention includes a material storage device, a primary kneading device, a kneading disc, and a driving device. The material storage device is installed above the primary kneading device and feeds the material into the primary kneading device. The bottom of the primary kneading device is provided with a discharge port. The bottom of the primary kneading device is placed on the kneading disc and moves in a circular motion around the center of the kneading disc under the action of the driving device. The upper surface of the kneading disc is provided with multiple raised ridges. Compared with the prior art, the present invention has the following main advantages:

[0023] (1) The initial kneading has been carried out during the feeding stage. With the help of the kneading disc, a second kneading can be achieved, making the kneading more thorough.

[0024] (2) The upper surface of the kneading disc of the present invention is provided with raised ridges. The bottom of the primary kneading device makes a circular motion on the kneading disc, similar to the motion of a grinding disc. The weight of the primary kneading device itself applies a certain pressure to the Chinese herbal medicine being kneaded, thereby improving the kneading effect. At the same time, the contact area between the bottom of the primary kneading device and the kneading disc is large, resulting in high kneading efficiency. In addition, the circular motion of the primary kneading device gradually drives the Chinese herbal medicine being kneaded toward the discharge port in the center of the kneading disc. Under the same total motion time, the kneading time of the herbal medicine is extended, allowing the Chinese herbal medicine to be fully kneaded.

[0025] (3) The Chinese medicinal materials kneaded by the present invention are in a state of kneading and moving forward from the top to the bottom. This ensures that each piece / piece of medicinal material is kneaded fully and evenly. Therefore, there is generally no problem of insufficient or uneven kneading, and the kneading effect is good.

[0037] The present invention will be further described in conjunction with the following embodiments and accompanying drawings. Example 1

[0038] The herbal medicine kneading machine of this embodiment includes a storage device, a primary kneading device, a kneading disc 3, and a driving device. The storage device is installed above the primary kneading device and feeds the primary kneading device. In this embodiment, the storage device is a storage tank 1-1, and the top of the storage tank 1-1 is provided with a feeding port 1-2.

[0039] In this embodiment, the initial kneading device includes a kneading outer cylinder 2-1 and a kneading inner wheel 2-2. The inner wall of the kneading outer cylinder 2-1 and the outer wall of the kneading inner wheel 2-2 are both provided with kneading protrusions 2-3. The kneading inner wheel 2-2 is equipped with an independent rotation drive device (mainly composed of a motor and a transmission device). The bottom of the kneading outer cylinder 2-1 is provided with a discharge port 2-4. The kneading inner wheel 2-2 rotates under the drive of the rotation drive device to knead the medicinal materials located between the kneading outer cylinder 2-1 and the kneading inner wheel 2-2 using the kneading protrusions 2-3 and slowly feed them into the kneading disc 3.

[0040] In this embodiment, the upper part of the inner kneading roller 2-2 is conical to allow the medicinal materials to fall more effectively between the inner wall of the outer kneading cylinder 2-1 and the outer wall of the inner kneading roller 2-2. The middle part is cylindrical to work with the inner wall of the outer kneading cylinder 2-1 to achieve a better kneading effect on the medicinal materials. The lower part is inverted conical. A bucket-shaped guide 2-5 is provided at the bottom of the outer kneading cylinder 2-1 to guide the medicinal materials after the initial kneading out of the discharge port 2-4 at the bottom of the outer kneading cylinder 2-1 and onto the kneading disc 3. The bottom of the initial kneading device is placed on the kneading disc 3 and moves in a circular motion around the center of the kneading disc 3 under the action of the driving device, thus kneading the Chinese medicinal materials.

[0041] To facilitate better kneading, the kneading disc 3 has a cylindrical shape with a central annular protrusion 3-43-2. ​​The upper surface of the kneading disc 3 has multiple arc-shaped ridges 3-1, with one end of each ridge converging at the annular protrusion 3-43-2. ​​This creates a downward-sloping, arc-shaped channel 3-3, wider at the outside and narrower at the inside, between adjacent ridges 3-1. With continuous feeding and the rotation and kneading of the initial kneading device, the medicinal materials move along the channel 3-3 towards the annular protrusion 3-43-2 until they fall into the collection box. To ensure thorough kneading, the diameter of the bottom of the kneading outer cylinder 2-1 in this embodiment is larger than the radius of the kneading disc 3.

[0042] The driving device in this embodiment can be a device of the prior art, as long as it can drive the initial kneading device to make a circular motion around the center of the kneading disc 3. It will not be described in detail here, and those skilled in the art should also clearly understand the structure and working principle of the driving device. Example 2

[0043] This embodiment is an improvement on Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that at least one annular convex ring is provided outside the annular convex ring 3-43-2 of the kneading disc 3. By providing the annular convex ring, the sliding speed of the medicinal materials can be reduced and the kneading in different directions can be increased, so that the medicinal materials are kneaded more thoroughly. Example 3

[0044] The main technical solution of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2. Features not explained in this embodiment adopt the explanations in Embodiment 1 or Embodiment 2, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that:

[0045] The driving device in this embodiment includes a motor (not shown in the figure), a drive shaft 4-1, a first bevel gear 4-2, a second bevel gear 4-3, a rotating shaft 4-4, a connector 4-5, a connecting vertical rod 4-6, a hinge arm 4-7, and a hinge support assembly. The motor drives the drive shaft 4-1 to rotate. The first bevel gear 4-2 is mounted on the drive shaft 4-1, and the second bevel gear 4-3 is mounted on the rotating shaft 4-4. The first bevel gear 4-2 and the second bevel gear 4-3 mesh and transmit power. The connecting piece 4-5 is fixedly connected to the rotating shaft 4-4. The upper end of the connecting vertical rod 4-6 is mounted on the connecting piece 4-5, and the lower end of the connecting vertical rod 4-6 is connected to the protruding arm 2-6 of the kneading outer cylinder 2-1 and hinged to one end of the hinge arm 4-7. The other end of the hinge arm 4-7 is hinged to the hinge support assembly. Here, "hinge" refers to a connection method where the connected components cannot move relative to each other at the connection point, but can rotate relative to each other, rather than necessarily using a hinge for connection.

[0046] In this embodiment, the kneading outer cylinder 2-1 has two or more protruding arms 2-6. The number of connecting vertical rods 4-6, hinged arms 4-7, and hinged support assemblies is the same as the number of protruding arms 2-6. One protruding arm 2-6, one connecting vertical rod 4-6, one hinged arm 4-7, and a set of hinged support assemblies together constitute a hinged unit. The hinged support assembly is located outside the kneading disc 3, which makes the initial kneading operation more stable. The hinged support assembly includes a support leg 4-8, a bearing 4-9, and a pin 4-10. The pin 4-10 passes through the hinged arm 4-7 and is rotatably mounted on the support leg 4-8 via the bearing 4-9. At the same time, the kneading disc 3 is mounted on the support leg 4-8, which makes the structure more compact, saves space, and does not require additional supports.

[0047] In this embodiment, the lower end of the rotating shaft 4-4 is fixedly connected to the kneading inner wheel 2-2. This allows the kneading inner wheel 2-2 to rotate while driving the initial kneading device, thus eliminating the need to install a separate rotation drive device, saving equipment costs and energy consumption.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the claims. Those skilled in the art should understand, with reference to the preferred embodiments, that modifications or equivalent substitutions can be made to the technical solutions of the present invention, but such modifications or substitutions shall fall within the substantially the same scope of protection as the technical solutions of the present invention.
