Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine reference material processing technology, and in particular to a multi-stage re-crushing device. Background Technology

[0002] When extracting reference standards for traditional Chinese medicine (TCM), the medicinal materials need to be thoroughly crushed before being processed through methods such as steaming or boiling to obtain the contained substances. Currently, most laboratory methods involve slicing or chopping the medicinal materials. This method of crushing effectively reduces the introduction of metal ions compared to grinding, and it is also suitable for some medicinal materials with significant differences in size, making grinding impractical. However, slicing or chopping results in larger particle sizes, which can negatively impact the extraction of TCM reference standards. Utility Model Content

[0003] This invention provides a multi-stage re-crushing device to overcome the shortcomings of the prior art and solve the problem of inconvenient and insufficient crushing of medicinal materials, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A multi-stage re-crushing device includes a tank, a crushing mechanism at the lower end of the tank, and a driving device at the upper end of the tank. In use, the tank is used to hold medicinal materials. The protection of the tank can prevent the medicinal materials from splashing during the crushing process. The crushing mechanism can scrape and crush the medicinal materials, and the crushed medicinal materials will be crushed again by grinding.

[0005] Furthermore, the inner circumference of the container is fixed with multiple retaining rings by screws. Multiple spaced outer blades are welded to the inner circumference of the retaining rings. The spacing between the outer blades facilitates the downward movement of the medicinal materials. In order to prevent the medicinal materials from staying on the outer blade located at the upper end, a ring can be fixed on the outer blade located at the upper end. The inner circumference of the ring has a conical structure, and the upper end of the inner circumference of the ring is the larger end.

[0006] Furthermore, the driving device includes a can lid screwed onto the upper end of the can body via a threaded connection. The outer circumference of the can lid is provided with an internal threaded ring, which is threaded to the upper end of the can body. A spline sleeve is welded to the upper end of the can lid, and a reciprocating central shaft passes through the spline sleeve. A conical disc is welded to the outer circumference of the reciprocating central shaft. The upper end of the conical disc is the small end, and the lower end of the conical disc is provided with a ring blade. The ring blade moves back and forth within the can body. During the reciprocating movement of the ring blade, its cutting edge and the outer blade move relative to each other, which can pulverize the medicinal materials between them. When the gap between the ring blade and the outer blade is large, the medicinal materials can pass through and be pulverized by the outer blades and the ring blade below. In order to improve the pulverization effect, the inner diameter of the ring blade increases from top to bottom, and the gap between the outer blade and the ring blade decreases from top to bottom, so as to fully scrape and pulverize the medicinal materials.

[0007] Furthermore, the crushing mechanism includes an inner ring fixed to the lower end of the tank body by screws. A lower plate is located on the outer periphery of the lower end of the inner ring, at the lower end of the tank body. Multiple support rods are threaded to the lower wall of the lower plate. A lower cone is formed at the upper end of the lower plate, with a conical outer periphery and a smaller upper end. A discharge hole is formed through the lower plate and the lower cone. A conical turntable is connected to the upper end of the lower cone via a bearing. A lower extension tube is provided at the lower end of the conical turntable, with its lower outer periphery positioned within the inner ring of the bearing. The outer ring of the bearing is fixed within an embedded groove at the upper end of the lower cone. A central hole is coaxially formed on the conical turntable, and the inner wall of the central hole is formed with… The spiral groove has an outer grinding ring installed on the lower inner circumference of the tank body via screws. Multiple spiral outer blades are welded to the lower inner circumference of the outer grinding ring. Multiple spiral inner blades are welded to the lower outer circumference of the conical turntable, with the spiral inner blades located inside the spiral outer blades. The lower end of the reciprocating central shaft passes through the central hole, and its lower end is equipped with an action pin, which passes through the spiral groove. When the reciprocating central shaft moves up and down, the action pin will act on the spiral groove, causing the conical turntable to reciprocate. During the rotation, the medicinal materials are thoroughly ground by the spiral outer and spiral inner blades, thus improving grinding efficiency and avoiding the problem of blade jamming through periodic blade retraction operations.

[0008] Furthermore, an upper extension column is provided at the upper end of the lower cone, which passes through the lower extension tube. The stability of the cone turntable can be improved by the upper extension column.

[0009] Furthermore, the upper inner circumference of the outer crushing ring is formed with a conical groove, and the lower end of the conical groove is a small end. This design facilitates the falling and discharge of medicinal materials.

[0010] Furthermore, the upper end of the reciprocating shaft is equipped with existing mechanical equipment with reciprocating function, such as a hydraulic cylinder, crankshaft motor mechanism, or cam motor mechanism to drive the reciprocating shaft to move. In order to improve the crushing efficiency, a motor-driven reciprocating mechanism can be used for grinding and crushing operations.

[0011] Furthermore, a pair of concave frames are installed on the can lid by screws. The upper end of the concave frame is equipped with a swing arm that rotates through a hinge shaft. The lower end of the swing arm is equipped with an action shaft. A horizontal plate is welded to the upper end of the reciprocating central shaft. A transverse hole is opened on the horizontal plate. The outer periphery of the action shaft abuts against the inner wall of the transverse hole. The above scheme facilitates the operator to manually raise and lower the reciprocating central shaft.

[0012] The advantages of the above technical solution are: This invention improves the pulverization efficiency and effect of medicinal materials by using multiple pulverization methods and a combination of grinding and pulverization. Attached Figure Description

[0019] like Figures 1-5 As shown, a multi-stage re-crushing device includes a tank 1, a crushing mechanism 2 at the lower end of the tank 1, and a driving device 3 at the upper end of the tank 1.

[0020] The inner circumference of the tank body 1 is fixed with multiple retaining rings 10 by screws, and multiple spaced outer blades 11 are welded to the inner circumference of the retaining rings 10.

[0021] The drive device 3 includes a can cover 300 screwed onto the upper end of the can body 1 via a threaded connection. The outer periphery of the can cover 300 is provided with an internal threaded ring 30, which is threaded onto the upper end of the can body 1. A spline sleeve is welded to the upper end of the can cover 300, and a reciprocating central shaft 46 passes through the spline sleeve. A conical disk 47 is welded to the outer periphery of the reciprocating central shaft 46. The upper end of the conical disk 47 is the small end, and a ring cutter 48 is provided on the lower outer periphery of the conical disk 47. The ring cutter 48 reciprocates and moves up and down within the can body 1.

[0022] The crushing mechanism 2 includes an inner ring 20 fixed to the lower end of the tank body 1 by screws. The lower outer periphery of the lower end of the inner ring 20 is provided with a lower plate 21. The lower plate 21 is located at the lower end of the tank body 1. The lower wall of the lower plate 21 is connected to multiple support rods 22 by threads. The upper end of the lower plate 21 is formed with a lower cone 24. The outer periphery of the lower cone 24 is conical, and the upper end of the outer periphery of the lower cone 24 is the smaller end. The lower plate 21 and the lower cone 24 are formed with a discharge hole 23. The upper end of the lower cone 24 is connected to a conical turntable 28 by a bearing. The lower end of the conical turntable 28 is provided with a lower extension tube 202. The lower outer periphery of the lower extension tube 202 is provided in the inner ring of the bearing. The outer ring of the bearing is fixed in the inner groove opened at the upper end of the lower cone 24. The upper end of the lower cone 24 is provided with an upper extension column 25, which passes through the lower extension tube 202. The conical turntable 28 has a central hole 201 coaxially formed. The inner wall of the central hole 201 is formed with a spiral groove 29. The lower end of the tank body 1 is fitted with an outer crushing ring 26 by screws. Multiple spiral outer plates 27 are welded to the lower end of the inner circumference of the outer crushing ring 26. The upper end of the outer crushing ring 26 is formed with a conical groove. The lower end of the conical groove is the small end. Multiple spiral inner plates 200 are welded to the lower end of the conical turntable 28. The spiral inner plates 200 are located inside the spiral outer plates 27. The lower end of the reciprocating central shaft 46 passes through the central hole 201 and is provided with an action pin at its lower end. The action pin passes through the spiral groove 29.

[0023] In this embodiment, when pulverizing medicinal materials, the medicinal materials are placed on the upper part of the tank 1, and then the operator screws the tank lid 300 onto the upper part of the tank 1. The operator then drives the reciprocating central shaft 46 to move back and forth through the reciprocating mechanism. During the movement, the ring blade 48 and the outer blade 11 interact to scrape the medicinal materials. When the ring blade 48 moves downward and is offset from the outer blade 11 above it by a certain distance, the movement of the ring blade 48 scrapes and pulverizes the medicinal materials. The pulverized medicinal materials fall downward between the conical turntable 28 and the outer pulverizing ring 26. When the reciprocating central shaft 46 moves back and forth, it acts on the spiral groove 29 through the action pin, thereby causing the conical turntable 28 to rotate. During the rotation, the medicinal materials are ground again by the inner spiral plate 200 and the outer spiral plate 27. The ground medicinal materials are discharged through the discharge hole 23.

[0024] In some embodiments, a hydraulic cylinder, crankshaft motor mechanism, or cam motor mechanism is installed at the upper end of the reciprocating central shaft 46 to drive the reciprocating central shaft 46 to move. When the reciprocating central shaft 46 moves back and forth, it is driven to move back and forth by the motor or hydraulic cylinder.

[0025] In some other embodiments, a pair of concave frames 4 are screwed onto the can lid 300. The upper end of each concave frame 4 is rotatably connected to a swing arm 41 via a hinge shaft. The lower end of the swing arm 41 is provided with an actuating shaft 43. A horizontal plate 44 is welded to the upper end of a reciprocating central shaft 46, and a transverse hole 45 is formed in the horizontal plate 44. The outer periphery of the actuating shaft 43 abuts against the inner wall of the transverse hole 45. In this embodiment, when the reciprocating central shaft 46 reciprocates, the swing of the swing arm 41 allows the actuating shaft 43 at its lower end to act on the transverse hole 45, thereby causing the reciprocating central shaft 46 to move reciprocally up and down.
