Description

Technical Field

[0001] The utility model relates to the field of Chinese medicine granule processing, in particular to a Chinese medicine granule granulating device. Background Art

[0002] The processing of Chinese medicine granules is usually completed by a rotary granulator, wherein the rotary granulator includes a feed barrel, a discharge barrel, a stirring component placed in the discharge barrel, and a scraper rotating around the outer wall of the discharge barrel. Its main mechanism is to set a ring-shaped mesh plate on the outer wall of the discharge barrel, use the stirring component to squeeze the material inside the discharge barrel, so that the material passes through the mesh plate and is discharged, and the granulation is completed with the help of the scraper outside the discharge barrel.

[0003] The existing patent publication number CN216024717U proposes a rotary granulator for processing traditional Chinese medicine. In the background technology, it is proposed that the current rotary granulator has the problem of low granulation rate due to the accumulation of materials in the middle area of ​​the discharge barrel. Therefore, it adds an arc block with an outer diameter increasing from top to bottom on the bottom wall of the inner cavity of the discharge barrel, so that the material can move along the edge of the discharge barrel under the action of gravity, thereby achieving the purpose of improving the granulation rate.

[0004] However, the above device still has certain defects: for example, when Chinese medicine granules are granulated, they are usually prepared by wetting the Chinese medicine powder with water, so the material has a certain adhesion force. Therefore, when the material uses its own gravity to move along the edge of the discharge barrel, it takes a long time, so there is still accumulation, resulting in a limited granulation rate.

[0005] Therefore, a kind of Chinese medicine granule granulating equipment is needed to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a granulating device for Chinese medicine granules, so as to accelerate the movement of materials along the edge of a discharging barrel and improve the granulating rate.

[0007] In order to solve the above technical problems, the utility model provides a Chinese medicine granule granulating device, including a feed cylinder, a discharge cylinder, a stirring component, a piston sleeve and a piston push rod;

[0008] The discharge barrel is fixedly connected to the feed barrel, and a plurality of discharge holes are arranged on the outer wall;

[0012] The piston sleeve is fixedly installed below the discharge cylinder and is rotatably connected and communicated with the end of the stirring sleeve;

[0013] The piston push rod is reciprocatingly slidably installed inside the piston sleeve.

[0014] Furthermore, a transmission member is provided between one end of the stirring sleeve extending to the outside of the discharging barrel and the piston push rod, so that the piston push rod moves back and forth while the stirring sleeve rotates.

[0015] Furthermore, the transmission member includes a driving disc and a hinged rod;

[0016] The driving disc is rotatably mounted below the discharge cylinder;

[0017] One end of the hinged rod is hinged to the edge of the driving disk, and the other end is hinged to the piston push rod.

[0018] Furthermore, the transmission member also includes a first bevel gear and a second bevel gear;

[0019] The first bevel gear is rotatably mounted on the outer wall of the piston sleeve through the output motor;

[0020] The second bevel gear is fixedly connected to the outer wall of the stirring sleeve and meshes with the first bevel gear.

[0021] Furthermore, the output motor is connected to the driving disc via a belt.

[0022] Furthermore, the inner diameter of the piston sleeve is larger than the inner diameter of the stirring sleeve.

[0023] Furthermore, the stirring sleeve and the piston sleeve are connected via a bearing, and a sealing ring is provided at the connection.

[0024] Furthermore, an L-shaped scraper is fixedly mounted on the outer wall of one end of the stirring sleeve extending to the outside of the discharge barrel;

[0026] Furthermore, the bottom wall of the inner cavity of the discharge barrel is arranged to be an isosceles trapezoidal structure, and the outer diameter increases from top to bottom.

[0027] Compared with the prior art, the utility model has at least the following beneficial effects:

[0028] By arranging a piston sleeve and a piston push rod, and making the piston sleeve communicate with the stirring sleeve of the stirring component, and respectively arranging a one-way air outlet and a one-way air inlet on the stirring sleeve, when the piston push rod moves back and forth in the piston sleeve, the one-way air outlet can eject air, so that the material located around the outer wall of the stirring sleeve moves in the direction away from the stirring sleeve (that is, moves along the edge position of the discharge barrel), thereby achieving the purpose of accelerating the movement of the material along the edge position of the discharge barrel, thereby improving the granulation rate when the extrusion roller and the discharge hole cooperate.

[0029] Furthermore, since the stirring sleeve and the piston sleeve can rotate relative to each other, that is, the operation of the piston push rod will not interfere with the operation of the stirring sleeve, the material can be moved along the edge of the discharge barrel while the stirring component is running, thereby shortening the time required for granulation and further improving the granulation rate.

[0033] The Chinese medicine granule granulating device of the utility model will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the utility model is shown, and it should be understood that those skilled in the art can modify the utility model described herein, and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the utility model.

[0034] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0035] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a Chinese medicine granule granulating device, including a feed cylinder 1, a discharge cylinder 2, a stirring component 3, a piston sleeve 4 and a piston push rod 5.

[0036] The discharge barrel 2 is fixedly connected to the feed barrel 1 and has a plurality of discharge holes 21 disposed on its outer wall. When the stirring component 3 is in operation, the extruded material is discharged from the discharge holes 21 to complete the granulation operation.

[0037] The stirring component 3 includes a stirring sleeve 31 and a plurality of squeezing rollers 32 fixedly installed outside the stirring sleeve 31 .

[0038] The stirring sleeve 31 is rotatably mounted inside the discharge barrel 2 , and one end extends to the outside of the discharge barrel 2 , so as to be conveniently connected with the piston sleeve 4 , so as to provide the stirring sleeve 31 with power for gas suction and discharge through the piston sleeve 4 and the piston push rod 5 .

[0039] The outer wall of the stirring sleeve 31 is provided with a plurality of one-way air outlet holes, so that air can be blown through the one-way air outlet holes to blow the material around the stirring sleeve 31, so that the material moves in a direction away from the stirring sleeve 31 (i.e., moves along the edge position of the inner cavity of the discharge barrel 2), so as to complete the granulation operation through extrusion by the extrusion roller 32, thereby improving the granulation rate.

[0040] It should be noted that the one-way air outlet can be set to be inclined, and inclined downward, so that the material can be subjected to the component force inclined downward, so as to increase the subsequent extrusion rate.

[0041] In addition, a one-way air inlet hole is provided on the top of the stirring sleeve 31, so that when the piston push rod 5 is in operation, it can inhale external air and discharge the air through the one-way air outlet hole.

[0042] Specifically, the piston sleeve 4 is fixedly installed below the discharge barrel 2, and is rotationally connected and communicated with the end of the stirring sleeve 31, and the piston push rod 5 is reciprocatingly slidably installed inside the piston sleeve 4. Through the reciprocating movement of the piston push rod 5 in the piston sleeve 4, gas is sucked from the one-way air inlet hole into the chamber formed by the piston sleeve 4 and the stirring sleeve 31, and the gas in the chamber is discharged from the one-way air outlet hole to achieve the blowing of the material, so as to accelerate the movement of the material along the edge of the discharge barrel 2 and improve the granulation rate.

[0043] The device is provided with a piston sleeve 4 and a piston push rod 5, and the piston sleeve 4 is connected with the stirring sleeve 31 of the stirring component 3, and a one-way air outlet and a one-way air inlet are respectively provided on the stirring sleeve 31. Then, when the piston push rod 5 moves back and forth in the piston sleeve 4, the one-way air outlet can jet, so that the material located around the outer wall of the stirring sleeve 31 moves in a direction away from the stirring sleeve 31 (that is, moves along the edge position of the discharge barrel 2), thereby achieving the purpose of accelerating the movement of the material along the edge position of the discharge barrel 2, thereby improving the granulation rate when the extrusion roller 32 and the discharge hole 21 cooperate.

[0044] Furthermore, since the stirring sleeve 31 and the piston sleeve 4 can rotate relative to each other, that is, the piston push rod 5 will not interfere with the operation of the stirring sleeve 31 when it is in operation, the material can be moved along the edge of the discharge barrel 2 while the stirring component 3 is in operation, thereby shortening the time required for granulation and further improving the granulation rate.

[0045] In other embodiments, in order to reduce equipment costs, a transmission member 6 is additionally provided so that only one output power is required to realize the synchronous operation of the stirring component 3 and the piston push rod 5. Accordingly, the synergy between the stirring component 3 and the piston push rod 5 can be effectively improved, and interference between components due to multiple output powers can be avoided.

[0046] Specifically, a transmission member 6 is provided between one end of the stirring sleeve 31 extending to the outside of the discharging barrel 2 and the piston push rod 5, so that the piston push rod 5 reciprocates while the stirring sleeve 31 rotates.

[0047] The transmission member 6 includes a driving disc 61 and a hinge rod 62 .

[0048] The driving disc 61 is rotatably mounted below the discharge barrel 2, one end of the hinged rod 62 is hinged to the edge of the driving disc 61, and the other end is hinged to the piston push rod 5. The driving disc 61, the hinged rod 62 and the piston push rod 5 form a crank slider mechanism, thereby realizing the reciprocating movement of the piston push rod 5 in the piston sleeve 4, so as to ensure the one-way air outlet can blow air.

[0049] It should be particularly noted that a limiting groove (not shown in the figure) for limiting the piston push rod 5 is provided inside the piston sleeve 4 to ensure that the piston push rod 5 only moves in the vertical direction, thereby ensuring the stability of the device operation.

[0050] In addition, the transmission member 6 further includes a first bevel gear 63 and a second bevel gear 64 .

[0051] The first bevel gear 63 is rotatably mounted on the outer wall of the piston sleeve 4 through the output motor 65, and the second bevel gear 64 is fixedly connected to the outer wall of the stirring sleeve 31 and meshes with the first bevel gear 63. That is, the output motor 65 is operated, and the first bevel gear 63 and the second bevel gear 64 mesh together to realize the rotation of the stirring sleeve 31, thereby ensuring the normal granulation of the material.

[0052] It should be particularly noted that the output motor 65 is connected to the drive disk 61 through a belt, so that the output motor 65 can drive the first bevel gear 63 to rotate while pulling the drive disk 61 to rotate. Therefore, the piston push rod 5 can move back and forth while the stirring component 3 is running, thereby effectively reducing the equipment cost and improving the stability of the equipment operation.

[0053] In other embodiments, in order to increase the gas discharge amount of the one-way gas outlet, the size of the piston sleeve 4 is further limited. Specifically, the inner diameter of the piston sleeve 4 is larger than the inner diameter of the stirring sleeve 31, so that when the piston push rod 5 moves, the suction change amount of the gas in the chamber formed by the piston sleeve 4 and the stirring sleeve 31 can be increased, and accordingly, the gas discharge amount of the one-way gas outlet can also be increased.

[0054] In a further embodiment, in order to improve the sealing performance between the stirring sleeve 31 and the piston sleeve 4 and prevent air leakage, a sealing ring 7 is provided. Specifically, the stirring sleeve 31 and the piston sleeve 4 are connected via a bearing, and a sealing ring 7 is provided at the connection.

[0055] In this embodiment, an L-shaped scraper 8 is fixedly mounted on the outer wall of one end of the stirring sleeve 31 extending to the outside of the discharge barrel 2 for scraping off the material squeezed by the squeezing roller 32 to the outside of the discharge hole 21 to form Chinese medicine particles.

[0056] The L-shaped scraper 8 is in close contact with the outer wall of the discharge barrel 2 .

[0057] Preferably, the bottom wall of the inner cavity of the discharge barrel 2 is set to an isosceles trapezoidal structure, and the outer diameter increases from top to bottom, so that the material can move autonomously along the edge of the inner cavity of the discharge barrel 2 under the action of gravity, thereby improving the preparation rate.

[0058] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
