[0002] In preparation of the Huoxiang Zhengqi Powder, the raw materials, i.e., medicinal materials such as agastache, perilla, radix angelicae dahuricae and magnolia officinalis, are usually dried and ground into fine powder first, and then all the medicinal material powders are mixed in proportion, screened to ensure uniformity, and finally sealed and stored in the dark.

[0003] In the raw material crushing process of the Huoxiang Zhengqi Powder in the prior art, the fibrous components and sticky substances contained in the medicinal materials such as agastache and perilla are prone to winding around the blades of the crusher, resulting in increased running resistance of the equipment and significantly reduced crushing efficiency; and if a shearing mechanism is additionally arranged on the blades of the crusher, although the fiber cutting effect can be improved, the mechanical friction between the blades and the shearing mechanism will cause local temperature rise, causing the medicinal materials containing fat-soluble components such as magnolia officinalis to soften under heat and then produce sticky clumps, and finally causing physical blockage of the screen mesh pores.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application will be further described below in conjunction with specific embodiments.

[0038] As Figures 1-5 shown, the raw material low-temperature crushing device for preparing Huoxiang Zhengqi Powder according to the embodiment of the present application comprises a mounting frame 1 and a body 2, the top of the mounting frame 1 is fixedly connected with the body 2, a screening device is arranged in the inner cavity of the body 2, a crushing mechanism is arranged in the inner cavity of the screening device, a feed hopper 3 is fixedly connected to one side of the body 2, and a discharge pipe 4 is fixedly connected to the bottom of the body 2.

[0039] The screen classifier is composed of mounting plates 5, mounting rings 6, connecting plates 7 and arc-shaped screen plates 8, the inner cavities of the machine body 2 are fixedly connected with the mounting plates 5, the opposite end faces of the two mounting plates 5 are sealingly and rotatably connected with the mounting rings 6, a plurality of connecting plates 7 are uniformly fixed between the two mounting rings 6, and the arc-shaped screen plates 8 are fixed between adjacent two connecting plates 7, one of the mounting plates 5 is provided with a through hole which is in communication with the bottom end of the feeding hopper 3;

[0040] The crushing mechanism is composed of crushing knives one 9, a rotating shaft one 10 and crushing knives two 11, a plurality of groups of the crushing knives two 11 are fixed on the rotating shaft one 10, the crushing knives one 9 are uniformly fixed on the connecting plates 7, the crushing knives one 9 are matched with the crushing knives two 11, the outer wall of the machine body 2 is provided with a driving assembly and a reciprocating moving assembly, the driving assembly can drive the mounting rings 6 and the rotating shaft one 10 to rotate, and the reciprocating moving assembly can drive the rotating shaft one 10 and the crushing knives two 11 to axially reciprocate;

[0041] The application considers that the raw materials for preparing Huoxiang Zhengqi Powder contain medicinal materials such as Agastache rugosa and Perilla frutescens, the fibers and viscous components in these medicinal materials are easy to wind around the blades in the crushing process of the crusher, which leads to the decrease of crushing efficiency or the jamming of the equipment, and if a shearing mechanism is arranged on the blades, the blades are easy to rub against the shearing mechanism and heat, which causes the softening and caking of Magnolia officinalis in the raw materials and blocks the screen, therefore, the application drives the rotating shaft one 10 to rotate forward at the same time through the driving assembly, and also reverses the screen classifier, so that the rotating directions of the crushing knives one 9 and the crushing knives two 11 are opposite, and the crushing knives two 11 can intermittently axially reciprocate through the cooperation of the reciprocating moving assembly, which facilitates the intermittent adhesion of the crushing knives one 9 and the crushing knives two 11, forms shearing action, reduces the winding of the raw materials around the blades, and also avoids excessive friction and heating, in addition, the reverse rotation of the crushing knives one 9 and the crushing knives two 11 facilitates the quick cutting of the raw materials, and improves the crushing effect on the raw materials;

[0042] When working, the staff puts the raw materials into the feeding hopper 3, after the raw materials enter the screen classifier composed of the mounting plates 5, the mounting rings 6, the connecting plates 7 and the arc-shaped screen plates 8, the screen classifier is reversed through the driving assembly, the crushing knives two 11 are driven to rotate forward by the rotating shaft one 10, the rotating shaft one 10 is intermittently axially reciprocated through the reciprocating moving assembly, the crushing knives one 9 are intermittently adhered to the crushing knives two 11, shearing action is formed, the raw materials wound around the crushing knives one 9 and the crushing knives two 11 are sheared and crushed, the crushed raw materials are discharged from the discharge pipe 4 below the machine body 2 through the arc-shaped screen plates 8, and the crushing work on the raw materials is completed.

[0043] As Figures 1-5As shown, the driving assembly includes support 14 and servo motor 15, the body 2 away from the side wall of the hopper 3 fixedly connected with support 14, support 14 is fixedly installed with servo motor 15, the output end of servo motor 15 is fixedly connected with synchronous wheel one 46 and synchronous wheel two 47, the one end of rotating shaft one 10 extends to the outside of the body 2 and is sleeved with limiting shaft 12, the one end of limiting shaft 12 is rotatably connected with mounting plate 5 and body 2, limiting shaft 12 is fixedly connected with synchronous wheel three 17, synchronous wheel one 46 and synchronous wheel three 17 are drivingly connected through synchronous belt one 16, the tooth ring 25 is fixedly connected on the mounting ring 6 away from the side of the hopper 3, the side of tooth ring 25 is meshingly connected with spur gear 24, the rotating shaft two 21 is fixedly connected on the spur gear 24, the one end of rotating shaft two 21 extends to the outside of the body 2 and is fixedly connected with synchronous wheel four 22, synchronous wheel two 47 and synchronous wheel four 22 are drivingly connected through synchronous belt two 23, rotating shaft two 21 is rotatably connected with mounting plate 5 and body 2;

[0044] The reciprocating moving assembly includes support 18 and electric telescopic rod 19, the outer wall of the body 2 is fixedly connected with support 18, support 18 is fixedly installed with electric telescopic rod 19, the output end of electric telescopic rod 19 is fixedly connected with rotating sleeve 20, the one end of rotating shaft one 10 is rotatably connected with rotating sleeve 20, the limiting groove 13 is symmetrically formed in the limiting shaft 12, the outer wall of rotating shaft one 10 is symmetrically provided with two limiting protrusions, the limiting protrusions are slidingly connected with the limiting grooves 13;

[0045] When working, after starting the crushing operation, the servo motor 15 and the electric telescopic rod 19 are started. The electric telescopic rod 19 here is prior art. The synchronous wheel one 46 and the synchronous wheel two 47 at the output end are driven to rotate by the servo motor 15, so that the synchronous wheel three 17 on the limiting shaft 12 is rotated under the driving of the synchronous belt one 16. At the same time, the synchronous wheel four 22 on the rotating shaft two 21 is rotated under the driving of the synchronous belt two 23, and the rotating direction of the limiting shaft 12 is the same as that of the rotating shaft two 21. The straight gear 24 on the rotating shaft two 21 drives the gear ring 25 and the mounting ring 6 to rotate. Because the rotating direction of the straight gear 24 is opposite to that of the gear ring 25, the rotating direction of the entire sifter is opposite to that of the rotating shaft one 10. In the process of crushing the raw materials in the sifter by the crushing knife two 11, the rotating sleeve 20 is intermittently axially reciprocated by the electric telescopic rod 19, so that the rotating shaft one 10 is intermittently axially reciprocated along the limiting groove 13 while rotating with the limiting shaft 12. And every time the rotating shaft one 10 moves into the sifter, the crushing knife two 11 will move to the adjacent crushing knife one 9 while rotating, until they can contact each other during rotation. Because the rotating directions of the crushing knife one 9 and the crushing knife two 11 are opposite, a shearing action is formed, which effectively prevents the raw materials from winding around the crushing knife one 9 and the crushing knife two 11, affecting the crushing effect. In addition, the electric telescopic rod 19 will drive the rotating shaft one 10 to reset after the crushing knife one 9 and the crushing knife two 11 rotate and temporarily adhere to each other, so that the crushing knife two 11 resets and moves away from the crushing knife one 9, preventing the crushing of the raw materials from being affected by the long-term excessive friction between the two.

[0046] As shown in Figure 1 , Figure 2 and Figure 7 , two blowing pipes 33 are arranged between the two mounting plates 5, the two blowing pipes 33 are distributed in an upper and lower manner, the outer wall top of the machine body 2 is fixedly installed with a gas pump 35, the gas pump 35 is communicated with an air inlet pipe 36, and the end of the air inlet pipe 36 away from the gas pump 35 extends into the inner cavity of the machine body 2 and is communicated with the inner cavities of the two blowing pipes 33.

[0047] The application also considers that although the screen can rotate under the drive of the driving assembly, part of the raw materials may still block the arc-shaped screen plate 8 during crushing, resulting in difficulty in screening discharge. Therefore, the application is provided with two air blowing pipes 33 above and below the screen, matched with the air pump 35 and the air inlet pipe 36, which can intermittently pump air into the air blowing pipe 33, so that the upper and lower air blowing pipes 33 can intermittently spray the top and bottom of the screen. The airflow can flush the arc-shaped screen plate 8 to prevent the crushed raw materials from blocking the arc-shaped screen plate 8. The air blowing mode arranged above and below can form a more uniform screening environment, so that light fine powder is preferentially taken out, while heavy particles continue to be crushed, improving the fine powder passing rate. In addition, the upward and downward air blowing can accelerate the dispersion of raw material particles, reduce the agglomeration phenomenon, and cooperate with the crushing knife one 9 and the crushing knife two 11 to make the crushing more uniform. The impact force generated by the airflow can further enhance the crushing effect on the raw materials. At the same time, the external airflow pumped by the air pump 35 helps to reduce the working temperature in the screen, maintaining the stability of the raw materials.

[0048] As shown in Figures 6-8 two air blowing pipes 33 are sealingly and rotatably connected with the branch shaft two 32, a plurality of air jet rings 34 are fixedly connected to the branch shaft two 32, the air jet ring 34 is rotatably connected with the air blowing pipe 33, an annular cavity and two air outlets are arranged in the air jet ring 34, one end of the branch shaft two 32 extends to the outside of the machine body 2, the outer wall of the machine body 2 is fixedly connected with the support three 27, the support three 27 is fixedly installed with the servo motor two 28, the outer wall of the machine body 2 is rotatably connected with the branch shaft one 31, the output end of the servo motor two 28, the branch shaft one 31 and the two branch shaft two 32 are fixedly connected with the synchronous wheel five 29, the synchronous wheel five 29 is drivingly connected through the synchronous belt three 30, the side of the air blowing pipe 33 facing the arc-shaped screen plate 8 is provided with an opening, the two air outlets of the air jet ring 34 are matched with the opening of the air blowing pipe 33;

[0049] It should be noted that, in order to prevent the crushed raw materials from blocking the air jet ring 34 on the air blowing pipe 33 during the shutdown of the air pump 35, the application can drive the two branch shaft two 32 to rotate reciprocatingly through the servo motor two 28 matched with the synchronous wheel five 29 and the synchronous belt three 30. Not only can the branch shaft two 32 drive the air jet ring 34 to rotate by ninety degrees during the shutdown of the air pump 35, so that the two air outlets of the air jet ring 34 directly fit the inner wall of the air blowing pipe 33, preventing the air jet ring 34 from being blocked, but also the air jet ring 34 can quickly rotate by ninety degrees when the air pump 35 supplies air, so that the air outlet of the air jet ring 34 corresponds to the opening on the air blowing pipe 33 again, realizing the spraying of the screen.

[0050] As shown in Figure 8 two air blowing pipes 33 are sealingly and rotatably connected with the branch shaft two 32, a plurality of air jet rings 34 are fixedly connected to the branch shaft two 32, the air jet ring 34 is rotatably connected with the air blowing pipe 33, an annular cavity and two air outlets are arranged in the air jet ring 34, one end of the branch shaft two 32 extends to the outside of the machine body 2, the outer wall of the machine body 2 is fixedly connected with the support three 27, the support three 27 is fixedly installed with the servo motor two 28, the outer wall of the machine body 2 is rotatably connected with the branch shaft one 31, the output end of the servo motor two 28, the branch shaft one 31 and the two branch shaft two 32 are fixedly connected with the synchronous wheel five 29, the synchronous wheel five 29 is drivingly connected through the synchronous belt three 30, the side of the air blowing pipe 33 facing the arc-shaped screen plate 8 is provided with an opening, the two air outlets of the air jet ring 34 are matched with the opening of the air blowing pipe 33;

[0051] When working, when the air pump 35 is started, the servo motor two 28 is started, and the two supporting shafts two 32 are driven to rotate through the synchronous wheel five 29 and the synchronous belt three 30, so that the jet rings 34 on the two blowing pipes 33 rotate, and then the air outlets are directed to the screening device. After that, the air flow is sent into the two blowing pipes 33 from the air inlet pipe 36 by the air pump 35, and finally is sprayed out from the air outlets of the jet rings 34. After blowing for a period of time, the servo motor two 28 drives the supporting shafts two 32 to rotate, so that the air outlets of the jet rings 34 are attached to the inner walls of the blowing pipes 33. In this process, the exposed part of the jet ring 34 passes through the scraper 45, and the surface of the jet ring 34 is cleaned through the scraper 45, so as to avoid that the surrounding of the air outlet of the jet ring 34 is attached by the fine powder of the raw materials and is blocked. After the rotation of the jet ring 34 is completed, the air pump 35 is stopped until it is started again after a period of time, so as to realize the intermittent jetting of the screening device.

[0052] As shown in Figures 9-10 , the inner cavity of the machine body 2 is fixed with a fixed frame 37 on both sides, the fixed frame 37 is rotatably connected with a knocking piece 38, the end of the knocking piece 38 away from the fixed frame 37 is column-shaped, the spring 39 is fixed between the knocking piece 38 and the inner wall of the machine body 2, the thickness of the connecting plate 7 is greater than that of the arc-shaped sieve plate 8, one side of the connecting plate 7 is fixed with a wedge-shaped block 40, the wedge-shaped block 40 is attached to the outer wall of the arc-shaped sieve plate 8, and the knocking piece 38 is matched with the arc-shaped sieve plate 8;

[0053] When working, in the process of the rotation of the screening device, the knocking piece 38 is always attached to the surface of the screening device under the elastic force of the spring 39. When the knocking piece 38 slides on the wedge-shaped block 40 from the arc-shaped sieve plate 8, the spring 39 is compressed, and the knocking piece 38 slides off the connecting plate 7. Since there is a thickness difference between the connecting plate 7 and the arc-shaped sieve plate 8, when the knocking piece 38 slides from the connecting plate 7 to the arc-shaped sieve plate 8, an impact is generated between the knocking piece 38 and the arc-shaped sieve plate 8 under the elastic force of the spring 39, so that vibration is formed, and the arc-shaped sieve plate 8 is further prevented from being blocked in the crushing process. At the same time, the effect of the vibration can make the raw materials more loose, so that the crushing knife one 9 cooperates with the crushing knife two 11 to crush.

[0054] As shown in Figure 3 and Figure 11 , the two mounting plates 5 are provided with water cooling cavities 41, the bottoms of the two water cooling cavities 41 are communicated with a water inlet pipe 43, the tops of the two water cooling cavities 41 are communicated with a water outlet pipe 44, the water inlet pipe 43 and the water outlet pipe 44 are all three-way pipes, the end of the water inlet pipe 43 away from the water cooling cavity 41 is connected with a water supply device, and the opposite sides of the two mounting plates 5 are embedded with metal heat-conducting sheets 42;

[0055] It needs to be further explained that in order to reduce the temperature in the screen during the crushing process, the water cooling cavity 41 is arranged in the mounting plate 5, and the metal heat conducting sheet 42 is arranged in the water cooling cavity 41, so that the heat generated in the screen during the crushing process can be quickly discharged and dissipated, and the raw materials are not affected by the temperature during the crushing process.

[0056] When working, the water inlet pipe 43 is connected with a water supply device such as a water pump, and cold water is continuously sent into the water cooling cavity 41 of the mounting plate 5 on both sides through the water inlet pipe 43. The cold water enters from the bottom of the water cooling cavity 41 and then flows into the water outlet pipe 44 from the top, and finally flows out along the water outlet pipe 44.
