Description

Technical Field

[0001] The present invention relates to the technical field of drug liquid extraction equipment, and in particular to a drug liquid extraction equipment for pharmaceutical research and development. Background Art

[0002] Medicines are substances or preparations for preventing, treating or diagnosing human and livestock diseases. Medicines are divided into natural medicines and synthetic medicines according to their sources. Before medicines are officially sold, a lot of research and development is required to ensure the safety and beneficial effects after use. The traditional method for extracting the active ingredients of existing herbal medicines is the grinding and filtration method, which is to put the herbal medicine into a grinding container and grind and filter it before extraction.

[0003] Generally, during grinding, the plant raw medicine is pounded by the grinding mechanism, and its autonomous movement range is large. It is not easy for the whole part to quickly receive sufficient grinding. After it is not fully broken, it is easy to entangle and intertwine together, making it difficult to change the overall posture, and thus not convenient to be quickly rolled to extract the liquid. At the same time, since the raw medicine is broken after grinding, the liquid is directly filtered without moving the raw medicine, which can easily cause blockage of the filtration channel and affect the discharge efficiency of the liquid. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the grinding process of the original medicine by the general grinding mechanism is not sufficient and rapid enough, and the discharge of the medicine liquid is easily affected by blockage. The present invention provides a medicine liquid extraction device for pharmaceutical research and development.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A drug liquid extraction device for pharmaceutical research and development includes a support plate, a central elliptical wheel rotatably mounted on the support plate, a rolling ring, and a transmission gear meshingly connected between the central elliptical wheel and the rolling ring. The outer periphery of the central elliptical wheel is movably connected to an outer row component, and the inner part of the rolling ring is movably connected to an extraction component.

[0007] Furthermore, the central elliptical wheel and the rolling ring are at the same rotation center, a sealing cover is movably clamped on the top of the rolling ring, the inner wall of the rolling ring is gathered at the waist to form a nest shape, and the transmission gear is driven and installed on the support plate.

[0008] Furthermore, the outer row component includes an annular groove penetrating the upper wall of the inner cavity of the rolling ring, a sealing ring slidably connected to the bottom of the annular groove, and a plurality of outer row holes penetrating the waist of the rolling ring, wherein elastic valve strips are slidably inserted in the outer row holes.

[0009] Furthermore, a plurality of valve grooves connected to the ring groove are provided at the bottom of the rolling ring, the elastic valve strip is slidably inserted in the valve groove, the bottom of the elastic valve strip includes a valve port corresponding to the outer row hole, the top of the elastic valve strip includes an L-shaped valve hole for exhausting air, and the outer row hole is vertically penetrated at the bottom of the valve groove.

[0010] Furthermore, the extraction component includes a connecting block fixed on the front and rear sides of the central elliptical wheel, a magnetic rolling block slidably engaged with the outer wall of the connecting block, an elastic bag fixed between the magnetic rolling block and the inner wall of the connecting block, and a ratchet mechanism meshingly connected to the bottom of the magnetic rolling block, a plastic heating rope is fixed between the ratchet mechanisms, a triangular caltrop is fixed on the plastic heating rope, and a magnetic ring for adjusting the movement of the magnetic rolling block is fixed on the support plate.

[0011] Furthermore, the surface of the elastic bag includes an intake valve port connected to the outside, the top of the connecting block includes a connecting portion that is slidably engaged with the annular groove, the connecting block is penetrated on the sealing ring, and the top of the connecting block includes an exhaust channel connecting the elastic bag and the annular groove.

[0012] Furthermore, the ratchet mechanism is rotatably mounted on the inner wall of the connecting block, and the ratchet mechanism includes an outer ratchet ring for meshing and connecting with the magnetic rolling block, and an inner ratchet gear connected to the plastic heating rope.

[0013] Furthermore, the magnetic ring includes a plurality of equidistantly arranged magnetic areas that repel the magnetic rolling block. The magnetic ring is sealed and connected to the periphery of the rolling ring and blocks the external discharge holes.

[0014] Furthermore, an outer row block is fixedly provided at the left end of the magnetic ring and is sealed and covered on the outer row holes.

[0015] The beneficial effects of the present invention are as follows:

[0016] The present invention drives the extraction component and the rolling ring to rotate in opposite directions through the central elliptical wheel, which is beneficial for the magnetic rolling block to increase the grinding effect of the original medicine. In conjunction with the intermittent repulsive effect of the magnetic circle on the magnetic rolling block, the ratchet mechanism drives the plastic heating rope to utilize the triangular caltrops to rotate unidirectionally to crack the original medicine, and cooperates with the homogenization of heat to increase the release of the medicine liquid. Since the original medicine is subjected to centrifugal force, under the interference of the triangular caltrops and the central elliptical wheel, the cracked part can continuously change its posture and always gather at the waist of the rolling ring, so as to be fully rolled and liquid extracted.

[0017] According to the present invention, when the grinding ring continuously rotates, the medicine liquid in the external discharge hole can be automatically thrown out due to the centrifugal force when passing through the external discharge block, so as to achieve the purpose of rapid collection. At the same time, when the magnetic grinding block moves to compress the elastic bag, the air inside the elastic bag fills the annular groove, and pressure is applied to each elastic valve strip, so that it moves downward to interrupt the external discharge of the medicine liquid, and reversely uses the external discharge hole to fill the inside with high-pressure air, so as to achieve the purpose of unblocking the external discharge hole, thereby ensuring the external discharge efficiency of the medicine liquid.

Implementation

[0027] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 1-8As shown, a liquid extracting device for pharmaceutical research and development includes a support plate 1, a central elliptical wheel 2 rotatably mounted on the support plate 1, a rolling ring 3, and a transmission gear 4 meshingly connected between the central elliptical wheel 2 and the rolling ring 3. The outer periphery of the central elliptical wheel 2 is movably connected with an outer row component 5, and the outer row component 5 includes an annular groove 51 penetrating the upper wall of the inner cavity of the rolling ring 3, a sealing ring 52 slidably connected to the bottom of the annular groove 51, and a plurality of outer row holes 53 penetrating the waist of the rolling ring 3. An elastic valve strip 54 is slidably inserted in the outer row hole 53, and the rolling ring 3 An extraction component 6 is movably connected inside, and the extraction component 6 includes a connecting block 61 fixed on the front and rear sides of the central elliptical wheel 2, a magnetic rolling block 62 slidably connected to the outer wall of the connecting block 61, an elastic bag 63 fixed between the magnetic rolling block 62 and the inner wall of the connecting block 61, and a ratchet mechanism 64 meshingly connected to the bottom of the magnetic rolling block 62. A plastic heating rope 65 is fixed between the ratchet mechanisms 64, and a triangular caltrop 66 is fixed on the plastic heating rope 65. A magnetic ring 67 for adjusting the movement of the magnetic rolling block 62 is fixed on the support plate 1.

[0029] More specifically, by placing the plant raw medicine between the central elliptical wheel 2 and the rolling ring 3, and applying a sealing cover 8 to completely seal it, starting the transmission gear 4 to rotate, and running the plastic heating rope 65 for heating, the central elliptical wheel 2, driven by the transmission gear 4, drives the extraction component 6 and the rolling ring 3 that is also meshing and rotating to rotate in the opposite direction. This design is conducive to the magnetic rolling block 62 to increase the effect of grinding the raw medicine. With the intermittent repulsion of the magnetic ring 67 on the magnetic rolling block 62, the ratchet mechanism 64 then intermittently drives the plastic heating rope 65 to rotate in one direction, so as to use the triangular thorn 66 to crack the raw medicine, and with the circumferential rotation of the plastic heating rope 65, the heat is homogenized, thereby increasing the release of the liquid medicine. Because the raw medicine is subjected to the centrifugal force, the triangular thorn 66 And under the interference of the central elliptical wheel 2, the cracked part can continuously change its posture and always gather at the waist of the grinding ring 3, and then cooperate with the periodic contraction and avoidance of the magnetic grinding block 62, so as to facilitate the adjustment of the posture of the original medicine, so that it can be fully rolled and liquid extracted. When the grinding ring 3 continues to rotate, the medicine in the outer discharge hole 53 based on the centrifugal force can be automatically thrown out when passing through the outer discharge block 7, so as to achieve the purpose of rapid collection. At the same time, when the magnetic grinding block 62 moves to compress the elastic bag 63, the air inside the elastic bag 63 fills the annular groove 51, and presses each elastic valve strip 54, so that it moves down to interrupt the discharge of the medicine, and reversely uses the outer discharge hole 53 to fill the inside with high-pressure air, so as to achieve the purpose of unblocking the outer discharge hole 53, thereby ensuring the discharge efficiency of the medicine.

[0030] like Figure 1-4As shown, in some embodiments, the central elliptical wheel 2 and the rolling ring 3 are at the same center of rotation, a sealing cover 8 is movably clamped on the top of the rolling ring 3, the inner wall of the rolling ring 3 is gathered at the waist to form a nest shape, and the transmission gear 4 is driven and installed on the support plate 1. After the plant raw medicine is placed between the central elliptical wheel 2 and the rolling ring 3 and completely sealed with the sealing cover 8, the central elliptical wheel 2 and the rolling ring 3 are controlled to rotate in opposite directions, so that the raw medicine is gathered at the waist of the rolling ring 3 due to centrifugal force and is ground and rolled, and the central elliptical wheel 2 can squeeze the raw medicine in a closed space to adjust the position and posture so that the raw medicine can be fully compressed.

[0031] like Figure 4-5 As shown, in some embodiments, a plurality of valve grooves connected to the ring groove 51 are opened at the bottom of the rolling ring 3, and the elastic valve strip 54 is slidably inserted in the valve groove. The bottom of the elastic valve strip 54 includes a valve port corresponding to the external discharge hole 53, and the top of the elastic valve strip 54 includes an L-shaped valve hole for exhausting air, and the external discharge hole 53 is vertically penetrated at the bottom of the valve groove.

[0032] like Figure 7-8 As shown, in some embodiments, the surface of the elastic bag 63 includes an intake valve port connected to the outside, the top of the connecting block 61 includes a connecting portion that is slidably engaged with the annular groove 51, the connecting block 61 is arranged on the sealing ring 52, and the top of the connecting block 61 includes an exhaust channel connecting the elastic bag 63 and the annular groove 51. When the elastic bag 63 is intermittently pressurized, the annular groove 51 is filled with air, and the elastic valve strip 54 is subsequently moved downward by the air pressure, interrupting the external discharge state of the external discharge hole 53 for clearing the blockage.

[0033] like Figure 2 and Figure 7 As shown, in some embodiments, the ratchet mechanism 64 is rotatably installed on the inner wall of the connecting block 61, and the ratchet mechanism 64 includes an outer ratchet ring for meshing with the magnetic grinding block 62, and an inner ratchet gear connected to the plastic heating rope 65. When the center elliptical wheel 2 drives the extraction component 6 to rotate, the plastic heating rope 65 applies an outward pulling force to the inner ratchet gear based on the centrifugal force, thereby ensuring the limitation of the inner ratchet gear, and the subsequent inner ratchet gear drives the plastic heating rope 65 to rotate in one direction.

[0034] like Figure 2 and Figure 4 As shown, in some embodiments, the magnetic ring 67 includes a plurality of equidistantly arranged magnetic zones that repel the magnetic grinding block 62. The magnetic ring 67 is sealed and connected to the periphery of the grinding ring 3, and the outer row hole 53 is blocked. When the magnetic grinding block 62 continues to rotate, the intermittent repulsion of the magnetic ring 67 is utilized, thereby facilitating the adjustment of the grinding and rolling state of the magnetic grinding block 62 and the control of the clearing process.

[0035] like Figure 1 As shown, in some embodiments, the left end of the magnetic ring 67 is fixedly provided with an outer row block 7 which is sealed and covered on the outer row hole 53 .

[0036] like Figure 7-8 As shown, in some embodiments, the external discharge component 5 includes an annular groove 51 penetrating the upper wall of the inner cavity of the rolling ring 3, a sealing ring 52 slidably connected to the bottom of the annular groove 51, and a plurality of external discharge holes 53 penetrating the waist of the rolling ring 3. An elastic valve strip 54 is slidably inserted in the external discharge hole 53. Specifically, when the rolling ring 3 rotates continuously, the medicine in the external discharge hole 53 due to the centrifugal force can be automatically thrown out when passing through the external discharge block 7, so as to achieve the purpose of rapid collection. When each elastic valve strip 54 is pressed and moved downward to interrupt the external discharge of the medicine, the external discharge hole 53 is used to fill the inside with high-pressure air, so as to achieve the purpose of unblocking the external discharge hole 53 and ensure the external discharge efficiency of the medicine.

[0037] like Figure 1-6 As shown, in some embodiments, the extraction component 6 includes a connection block 61 fixed on the front and rear sides of the central elliptical wheel 2, a magnetic rolling block 62 slidably connected to the outer wall of the connection block 61, an elastic bag 63 fixed between the magnetic rolling block 62 and the inner wall of the connection block 61, and a ratchet mechanism 64 meshingly connected to the bottom of the magnetic rolling block 62. A plastic heating rope 65 is fixed between the ratchet mechanism 64, and a triangular caltrop 66 is fixed on the plastic heating rope 65. A magnetic ring 67 for adjusting the movement of the magnetic rolling block 62 is fixed on the support plate 1. Specifically, the extraction component 6 is driven by the central elliptical wheel 2. Part 6 rotates in opposite directions to the rolling ring 3, which is beneficial for the magnetic rolling block 62 to increase the grinding effect on the original medicine. In conjunction with the intermittent repulsion of the magnetic ring 67 on the magnetic rolling block 62, the ratchet mechanism 64 then drives the plastic heating rope 65 to use the triangular caltrops 66 to rotate unidirectionally to break the original medicine, and cooperates with the heat homogenization to increase the release of the medicine liquid. Since the original medicine is subjected to centrifugal force, under the interference of the triangular caltrops 66 and the central elliptical wheel 2, the broken part can continuously change its posture and always gather at the waist of the rolling ring 3, so as to be fully rolled and liquid extracted.
