Description

Nux vomica reducing mechanism

Technical Field

The invention relates to the technical field of traditional Chinese medicine processing equipment, in particular to a nux vomica crushing device.

Background

Semen Strychni is dry mature seed of Loganiaceae plant Logania japonica (Strychnos nux-vomica L.), and is one of the commonly used toxic traditional Chinese medicines in clinical practice of traditional Chinese medicine. It is bitter in taste, cold in nature and extremely toxic, has the effects of dredging collaterals, relieving pain, resolving hard mass and eliminating swelling, and can be used as a medicine. Because of the extremely strong toxicity of the nux vomica, the clinical report of the nux vomica poisoning is frequently found, which greatly limits the clinical application of the nux vomica. Therefore, the research on the attenuation (storage) effect of nux vomica becomes a research hotspot in recent years.

The chemical components of nux vomica comprise alkaloids, glycosides, organic acids, fatty oil, protein, polysaccharide and the like, wherein the alkaloids are the main effective components. The alkaloid includes strychnine, isostrychnine, isomerocarpine, pseudostrychnine, strychnine oxynitride, strychnine, alpha-colubulin, beta-colubulin, norfadrogen, icarin, strychnine, isobamurenine oxynitride, and 2-hydroxy-3-methoxy brucine. In the above alkaloids, strychnine and strychnine are main components, and strychnine accounts for 50% of total alkaloids, and strychnine accounts for 30% -40%. Raw nux vomica has severe toxicity, and strychnine which are alkaloid components are both effective components and toxic components, wherein strychnine has the strongest toxicity, and the treatment amount is very close to the toxic amount, 5-10mg of strychnine can cause poisoning and 30mg can cause death after 1 adult takes the strychnine, and 5mg of strychnine can cause death of children after oral taking. Therefore, strychnos nux-vomica seed is usually processed and then used as a medicine.

After processing semen strychni, the processed semen strychni is generally required to be crushed to be prepared into a test sample, so as to detect the content of strychnine nitrogen oxide and strychnine nitrogen oxide in the test sample. However, the conventional nux vomica crushing device usually needs to manually replace the screen to crush the nux vomica particles or powder with different particle sizes, and the efficiency is poor.

Under the action of the conveying assembly 520, the conveying assembly 520 first conveys the original screen assemblies 400 below the crushing assembly 300 into the storage assembly 510 for storage, and then conveys the target screen assemblies 400 stored in the storage assembly 510 to the position below the crushing assembly 300, so as to achieve the purpose of replacing the screen assemblies 400.

The screen assembly 400 with the structure has the advantages of simple structure, reasonable design and convenient operation.

In one embodiment, storage assembly 510 includes a storage socket 511, a second drive assembly, and a third drive assembly.

The storage seat 511 is sequentially provided with a plurality of storage slots at intervals along the longitudinal direction. In use, each storage slot stores a mesh number of screen assemblies 400. The storage seat 511 is movable in a reciprocating linear motion along the longitudinal direction between a first working position a and a second working position a. Specifically, when the storage seat 511 is located at the first working position a, the storage slot located at the lowest position corresponds to the conveying element 520, and when the storage seat 511 is located at the second working position a, the storage slot located at the highest position corresponds to the conveying element 520. That is, the first working position a of the storage seat 511 is higher than the second working position a of the storage seat 511.

The storage seat 511 is also movable in a reciprocating rectilinear motion in the transverse direction between a first working position B and a second working position B. Specifically, when the storage seat 511 is located at the first working position B, the storage seat 511 is far away from the transportation component, and when the storage seat 511 is located at the second working position B, the storage seat 511 is close to the transportation component.

The second driving component is in transmission connection with the storage seat 511, and is used for driving the storage seat 511 to perform reciprocating linear motion between the first working position a and the second working position a. Specifically, the second driving assembly includes a first slider 512 and a step-by-step electric push rod 513. First sliding grooves are formed in two sides of the top of the storage seat 511, and the two first sliding blocks 512 are respectively arranged in the first sliding grooves in a sliding manner, so that the first sliding blocks 512 can slide along the transverse direction. The two stepping electric push rods 513 are fixedly mounted on the base 100, and power output shafts of the two second electric push rods are respectively and fixedly connected with the two first sliding blocks 512. Specifically, the stepping electric push rod 513 drives the storage seat 511 to ascend or descend by a distance L each time it is activated, wherein L is equal to the distance between any two adjacent storage slots. When the stepping type electric push rod 513 is extended, the storage seat 511 can be driven to move from the second working position a to the first working position a, and on the contrary, the stepping type electric push rod 513 is retracted, the storage seat 511 can be driven to move from the first working position a to the second working position a.

The third driving component is in transmission connection with the storage base 511, and is used for driving the storage base 511 to perform reciprocating linear motion between the first working position B and the second working position B. Specifically, the third driving assembly includes a second slider 514 and a first electric push rod 515. A slide rail is fixedly installed on the base 100, and the second slider 514 is slidably connected to the slide rail, so that the second slider 514 can slide along the longitudinal direction. The first electric push rod 515 is fixedly connected to the second sliding block 514, and a power output shaft of the first electric push rod 515 is fixedly connected to the storage base 511. When the storage device is used, the first electric push rod 515 extends to move the storage seat 511 from the first working position B to the second working position B, and conversely, the first electric push rod 515 retracts to move the storage seat 511 from the second working position B to the first working position B.

When the device is used, the stepping electric push rod 513 extends or retracts, so as to drive the storage seat 511 to ascend or descend, thereby achieving the purpose of enabling different storage slots to correspond to the transportation assemblies. The first electric push rod 515 is extended or retracted so as to move the storage seat 511 toward or away from the transportation unit.

In one embodiment, storage assembly 510 further includes a stop assembly for preventing a change in position of screen assembly 400 on storage base 511 during movement of storage base 511 by the second drive assembly and/or the third drive assembly. The limiting assembly comprises a plurality of limiting units arranged in a circular array, and each limiting unit comprises a limiting hole 516, a limiting pin 517 and a first elastic piece 518.

A retaining hole 516 is opened in the bottom of the screen assembly 400. The limiting pin 517 is matched with the limiting hole 516 to achieve the purpose of limiting, and one end of the limiting pin 517 facing the limiting hole 516 is spherical or hemispherical. Specifically, a first mounting hole is formed in the side wall of the bottom of the storage slot, and the limit pin 517 is mounted in the first mounting hole. When the screen assembly 400 is used, one end of the limiting pin 517 facing the limiting hole 516 is inserted into the limiting hole 516, and the part of the limiting pin 517 inserted into the limiting hole 516 is smaller than or equal to one half of a sphere, so that when the transverse external force of the screen assembly 400 reaches a certain value, the screen assembly 400 can force the limiting pin 517 to overcome the elastic force of the first elastic piece 518 to move into the first mounting hole, and the screen assembly 400 can be pulled out from the storage slot.

The two ends of the first elastic element 518 are respectively connected with the limit pin 517 and the storage seat 511. Specifically, the first elastic element 518 is installed in the first installation hole, and two ends of the first elastic element are respectively abutted against the limit pin 517 and the storage seat 511. And in a natural state, the first elastic element 518 tends to move the limiting pin 517 toward the limiting hole 516.

During the use, after inserting screen cloth subassembly 400 in the storage slot, spacing hole 516 is corresponding with spacer pin 517, and under the effect of the elasticity of first elastic component 518, spacer pin 517 inserts in spacing hole 516 to reach and carry out spacing purpose to screen cloth subassembly 400.

When the lateral external force (i.e. the external force for pulling the screen assembly 400 out of the storage slot) applied to the screen assembly 400 is greater than a predetermined value, the limiting pin 517 is forced to overcome the elastic force of the first elastic member 518 under the action of the sidewall of the limiting hole 516, so as to pull the screen assembly 400 out of the storage slot.

The limiting assembly with the structure is simple in structure and reasonable in design.

In one embodiment, the transport assembly 520 includes a swing arm 521, a gripper assembly, and a fourth drive assembly 522.

The swing arm 521 has a first end pivotally connected to the base 100 and a second end reciprocally swingable about a rotation center line thereof between a first working position C and a second working position C. Specifically, when the second end of the swing arm 521 is in the first operating position C, the second end of the swing arm 521 faces the storage seat 511, and when the second end of the swing arm 521 is in the second operating position C, the second end of the swing arm 521 faces the size reduction assembly 300.

A gripper assembly is mounted at a second end of the swing arm 521 for gripping or releasing the screen assembly 400.

The power output end of the fourth driving assembly 522 is in transmission connection with the power input end of the swing arm 521, and is used for driving the swing arm 521 to swing. Specifically, the fourth driving assembly 522 includes a second motor or a rotary cylinder, the second motor or the rotary cylinder is fixedly mounted on the base 100, and a power output shaft thereof is in transmission connection with a first end of the swing arm 521.

In one embodiment, the grasping assembly includes an arcuate slot 523 and a first electromagnet 524.

The arc-shaped groove 523 is arranged at the second end of the swing arm 521, and the inner diameter of the arc-shaped groove 523 is matched with the outer diameter of the screen assembly 400. Specifically, the inner diameter of the arc-shaped groove 523 is adapted to the outer diameter of the mounting frame 410, and the central angle corresponding to the radian of the arc-shaped groove 523 is α, wherein α is greater than or equal to 90 ° and less than or equal to 180 °. The first electromagnet 524 is fixedly embedded on the inner wall of the arc-shaped groove 523. Specifically, the number of the first electromagnets 524 is multiple, the inner wall of the arc-shaped groove 523 is provided with a second mounting hole, and the first electromagnets 524 are fixedly embedded in the second mounting hole. In use, the first electromagnet 524 is energized to attract the screen assembly 400 and the first electromagnet 524 is de-energized to release the screen assembly 400.

Preferably, the outer diameter of the side of the storage seat 511 facing the conveying assembly 520 is adapted to the inner diameter of the arc-shaped groove 523, so that after the grabbing assembly inserts the original screen assembly 400 at the bottom of the crushing assembly 300 into the storage slot, the second driving assembly can directly drive the storage seat 511 to ascend or descend, so that the target screen assembly 400 corresponds to the swing arm 521, without the need that the third driving assembly first drives the storage seat 511 to be far away from the swing arm 521, and after the second driving assembly drives the target screen 420 to correspond to the swing arm 521, the third driving assembly drives the storage seat 511 to be close to the swing arm 521. Thereby shortening the operation steps of the grabbing assembly when grabbing the target screen assembly 400.

The grabbing component with the structure is simple in structure and reasonable in design.

Specifically, the body 200 is provided with a first slot, so that the screen assembly 400 can be inserted into the first slot and inserted into or pulled out of the first slot in the process that the swing arm 521 carries the screen assembly 400 to reciprocate between the first working position C and the second working position C.

In one embodiment, the locking assembly includes a plurality of locking units arranged in a circular array, and the locking unit 610 includes a locking receptacle 611, a locking bolt 612, and a fifth drive assembly.

A locking socket 611 opens at the bottom of the screen assembly 400. Preferably, the locking insertion holes 611 may coincide with the position-limiting holes 516, that is, the position-limiting holes 516 are used as locking holes, so as to reduce the number of holes formed in the screen assembly 400. Specifically, the locking insertion hole 611 opens at the bottom of the mounting frame 410.

The locking latch 612 is fitted into the locking receptacle 611, which is mounted on the body 200. Specifically, the bottom of the first slot is provided with a mounting hole, and the locking bolt 612 is slidably mounted in the mounting hole. The deadbolt 612 is longitudinally reciprocally linearly movable between a first operative position D and a second operative position D. Wherein when the latching pin 612 is in the first position D, the latching pin 612 extends out of the side wall of the first slot so that the latching pin 612 can be inserted into the latching hole 611, and when the latching pin 612 is in the second working position D, the latching pin 612 retracts into the side wall of the first slot so that the latching pin 612 can be pulled out of the latching hole 611.

A fifth drive assembly is mounted to the housing 200 and/or the deadbolt 612 for driving the deadbolt 612 in reciprocating linear motion between the first operating position D and the second operating position D.

In use, the fifth driving assembly drives the latching pin 612 to the first operating position D such that the latching pin 612 is inserted into the latching receptacle 611, thereby locking the screen assembly 400 in the first slot, i.e., below the size reduction assembly 300. The fifth drive assembly drives the deadbolt 612 to the second operating position D such that the deadbolt 612 is pulled out of the lock receptacle 611 for the purpose of unlocking the screen assembly 400, and then the fourth drive assembly 522 drives the swing arm 521 from the second operating position C to the first operating position C for the purpose of transporting the screen assembly 400.

In one embodiment, the fifth driving assembly includes a permanent magnet 613, a second electromagnet 614, and a second elastic member 615.

The permanent magnet 613 is fixedly mounted on the bottom end of the locking pin 612. The second electromagnet 614 is installed below the permanent magnet 613 and is fixedly connected to the machine body 200. Specifically, the second electromagnet 614 is fixedly embedded at the bottom end of the second mounting hole. The second elastic member 615 is installed in the second installation hole, and both ends thereof are respectively connected with the locking bolt 612 and the body 200.

When the second electromagnet 614 is energized, if the opposite side of the second electromagnet 614 and the permanent magnet 613 is the same in magnetism, that is, when the second electromagnet 614 is energized, a magnetic repulsive force is generated between the second electromagnet 614 and the permanent magnet 613. The second elastic member 615 has a tendency to move the latching pin 612 away from the latching receptacle 611 in a natural state.

When the second electromagnet 614 is energized, if the magnetism of the opposite side of the second electromagnet 614 and the permanent magnet 613 is opposite, that is, the second electromagnet 614 is energized, magnetic attraction is generated between the second electromagnet 614 and the permanent magnet 613. The second elastic member 615 has a tendency to move the latching pin 612 toward the latching insertion hole 611 in a natural state. Preferably, the second electromagnet 614 is opposite in polarity to the opposite side of the permanent magnet 613. In use, the second electromagnet 614 is energized, and under the action of the magnetic attraction between the second electromagnet 614 and the permanent magnet 613, the locking bolt 612 overcomes the elastic force of the second elastic member 615, so as to move downwards from the first working position D to the second working position D, and thus the locking bolt 612 is pulled out of the locking insertion hole 611. When the second electromagnet 614 is powered off, the locking latch 612 moves upward from the second working position D to the first working position D under the elastic force of the second elastic member 615 to be inserted into the locking socket 611, so as to lock the screen assembly 400.

The working principle of the invention is as follows:
