Description

Technical Field

[0001] The present invention relates to the technical field of medicine screening, and more specifically, to a particle medicine screening device. Background Art

[0002] The particle size of pharmaceutical raw materials is uneven after being crushed, and they need to be screened before mixing. Screening refers to the process of using one or more sieves to classify materials according to particle size, also known as screening. Drug screening is to obtain drugs with more uniform particle size, which is beneficial to improve the uniformity of the later preparation of the mixture. In the screening process, a pharmaceutical-specific vibrating screen must be used to screen out materials with qualified particle size. Common drug screening equipment includes hand-cranked screens, rotary vibrating screens and electromagnetic vibrating screens. At present, hand-cranked screens are often used for drug screening in the laboratory or in the pharmaceutical background of small batch demand.

[0003] At present, when screening drug particles with hand-cranked sieves, on the one hand, due to the different shapes and irregular surface conditions of drug particles, drug particles are easily attracted and adhered to each other, so that the particles will agglomerate into blocks or block the sieve holes during the screening operation, resulting in the sieve being unable to operate normally. On the other hand, the current screening method between the sieve and the drug particles is that the sieve is directly contacted and then collided, and the screening process is mostly rigid collision, resulting in the problem of drug particles being destroyed in batch screening, thereby affecting the screening quality and accuracy of the drugs. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a granular medicine screening device, which is provided with sieve holes, conical holes, a toggle plate, a deformation notch and an arc-shaped touch plate; during the swinging process of the toggle plate, it will collide and contact with the drug particles in a tilted posture in real time, thereby always providing an oblique downward force to the drug particles to assist their rapid screening, and the collision contact effect of the toggle plate on the drug particles and the expansion effect of the conical hole are coordinated with each other to avoid a large number of particles from sticking and clogging during the screening process. At the same time, the toggle plate will contact the drug particles in a vibrating posture after the collision, thereby transmitting the vibration to the drug particles at the moment of the collision. Therefore, the two are non-rigid collisions during the collision, and there is vibration flexibility between the two, thereby achieving a flexible screening effect to solve the problems raised in the above-mentioned background technology.

[0009] The toggle plate, the deformation notch and the arc-shaped touch plate satisfy the following movement rules during operation:

[0010] The maximum movement amount of the bottom end of the toggle plate elastically deforming toward one side of the central axis of the sieve hole does not exceed the outer edge of the sieve hole. When the toggle plate elastically deforms toward the other side, the maximum movement amount is reached when the arc-shaped touch plate contacts and collides with the inner wall of the tapered hole. When the toggle plate is in a reciprocating swinging state and contacts with material particles under the external force of the user's shaking, the outer side of the toggle plate always maintains an inclined distribution with the material particles, and the inclination direction is always perpendicular to the surface of the toggle plate and points obliquely downward.

[0011] The upper and lower ends of the screening net are respectively provided with sealing covers and bottom support boxes which can be detachably buckled, and the contact positions of the sealing covers and bottom support boxes with the screening net are both in a sealed state.

The present invention provides sieve holes, conical holes, a toggle plate, a deformed notch and an arc-shaped touch plate; during the swinging process of the toggle plate, it will collide and contact with the drug particles in a tilted posture in real time, and the direction of the tilted collision is always perpendicular to the surface of the toggle plate and points obliquely downward, thereby always providing an oblique downward force on the drug particles to assist them in rapid screening, and synchronously utilizing the design that the conical holes gradually expand outward when the drug particles enter the conical holes, so that the internal volume for the drug particles is gradually increased, thereby improving the screening speed of the drug particles, and the collision and contact effect of the toggle plate on the drug particles cooperates with the expansion effect of the conical holes, which can avoid the problem of a large number of particles sticking and clogging during the screening process;

[0020] On the other hand, during the swinging back and forth of the toggle plate, the arc-shaped touch plate on one side of the bottom end of the toggle plate will contact the inner wall of the conical hole and generate a high-frequency and low-amplitude collision, and the vibration generated by the collision will be gradually transmitted to the entire toggle plate through the arc-shaped touch plate. Then the toggle plate swings back and forth with a high-frequency and low-amplitude vibration posture. Therefore, when the toggle plate collides with the drug particles during the swinging process, the toggle plate will contact the drug particles in a vibrating posture after the collision, thereby transmitting the vibration to the drug particles at the moment of the collision. Therefore, the two are non-rigid collisions during the collision, and there is vibration flexibility between the two, thereby achieving a flexible screening effect, and can further assist in the rapid screening of drug particles, further improving its practicality.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As attached Figure 1 To Attachment Fig.11 A particle medicine screening device shown in the figure comprises a screening net 1, handles 2 are respectively provided on both sides of the screening net 1, a plurality of screen holes 3 are provided in a ring array at the top of the screening net 1, a plurality of the screen holes 3 are connected at the bottom ends thereof and are provided with a conical hole 4, the overall cross-section of the conical hole 4 is conical, the end with a smaller diameter of the conical hole 4 is connected to the bottom end of the screen hole 3, and the overall diameter of the screen hole 3 is the same as the top diameter of the conical hole 4, the matching design between the screen hole 3 and the conical hole 4 is adopted, so that the drug particles can be screened smoothly, and the subsequent flexible auxiliary screening is performed, so as to ensure the screening effect of the drug particles;

[0035] A plurality of connecting seats 51 are installed in a ring-shaped array on the top of the inner wall of the conical hole 4, and a toggle plate 52 is integrally formed at the bottom of the connecting seat 51. A deformation notch 53 is provided on the side of the toggle plate 52 close to the inner wall of the conical hole 4, and an arc-shaped touch plate 54 is fixedly installed on the bottom of the toggle plate 52 and on the same side of the deformation notch 53. Wedge-shaped intervals 6 are formed in sequence from top to bottom between the inner edge of the toggle plate 52 and the inner wall of the side of the conical hole 4. The setting of the wedge-shaped intervals 6 can ensure that the toggle plate 52 can swing smoothly in the conical hole 4, and in one swinging cycle, the arc-shaped touch plate 54 collides with the inner wall of the conical hole 4, so as to charge the toggle plate 52 as a whole for collision, so as to ensure that it is always in a high-frequency vibration state, thereby ensuring its screening effect on drug particles.

[0036] The two sides of the overall shape of the toggle plate 52 are sequentially designed to shrink in an involute shape from top to bottom, and the inclination of one side of the toggle plate 52 close to the inner wall of the tapered hole 4 is greater than the inclination of the other side. The overall area of ​​the wedge-shaped spacer 6 is oppositely distributed to the overall shape of the toggle plate 52. The wedge-shaped spacer 6 and the toggle plate 52 are designed in an opposite manner, so that the matching state of the two is consistent with the swing trajectory of the toggle plate 52, thereby ensuring that the normal inertial swing amplitude of the toggle plate 52 can be carried out smoothly;

[0037] In the initial state: the overall inclination of the toggle plate 52 is consistent with the inclination of the inner wall side of the tapered hole 4, the bottom end of the toggle plate 52 is kept on the same horizontal line as the bottom end of the tapered hole 4, the overall inclination of the deformation slot 53 is consistent with that of the toggle plate 52, and an extension line is made at the midpoint of the deformation slot 53, the extension line is consistent with the inclination of the toggle plate 52, and at this time, the extension line is perpendicular to the outer track of the toggle plate 52, the side of the connecting seat 51 and the side of the sieve hole 3 are located outside the overall range of the sieve hole 3, and the two The contact point of the arc touch plate 54 is kept horizontally distributed. The arc touch plate 54 is set in an arc surface as a whole, and the surface of the arc touch plate 54 is set in a frosted state. The above-mentioned setting can ensure that after the arc touch plate 54 contacts the inner wall of the tapered hole 4, the contact point between the two remains stable and is not prone to excessive and unnecessary sliding. At the same time, the overall deformation notch 53 is kept consistent with the inclination of the toggle plate 52, so that it can follow the swing deformation trajectory of the toggle plate 52 and provide auxiliary deformation to its swing deformation trajectory, ensuring that it is easily excited and in a swinging state after being affected by external force;

[0038] The toggle plate 52, the deformation notch 53 and the arc-shaped touch plate 54 satisfy the following movement rules during operation:

[0039] The maximum movement amount of the bottom end of the toggle plate 52 elastically deforming toward one side of the central axis of the sieve hole 3 does not exceed the outer edge of the sieve hole 3. When the toggle plate 52 elastically deforms toward the other side, the maximum movement amount is reached when the arc-shaped touch plate 54 contacts and collides with the inner wall of the conical hole 4. When the toggle plate 52 is in a reciprocating swinging state under the external force of the user's shaking and contacts with the material particles, the outer side of the toggle plate 52 always maintains an inclined distribution with the material particles, and the inclination direction is always perpendicular to the surface of the toggle plate 52 and points obliquely downward. The above-mentioned arrangement ensures that the outer side of the toggle plate 52 always maintains an inclined distribution with the material particles and points obliquely downward, so that the screening process of the drug particles always tends to the outlet direction of the conical hole 4 for screening, ensuring its flexible screening while improving its screening smoothness and avoiding the situation of particle parts sticking and stagnating.

[0040] The upper and lower ends of the screening net 1 are respectively detachably fastened with a sealing cover 7 and a bottom support box 8, and the contact positions of the sealing cover 7 and the bottom support box 8 with the screening net 1 are both in a sealed state. The sealing cover 7 can be used to seal the top of the screening net 1, and the bottom support box 8 can be used to accommodate the drug particles screened by the screening net 1.

[0041] The arc-shaped touch plate 54 can be made of any one of metal materials, resin materials or PP materials. The inner side of the sieve hole 3 is seamlessly connected to the connection point of the connecting seat 51. The outer edges of the entirety of the toggle plate 52 and the connecting seat 51 are rounded. The surface of the toggle plate 52 is provided with a layer of polymer composite material. The outer edges of the entirety of the toggle plate 52 and the connecting seat 51 are rounded. The surface of the toggle plate 52 is provided with a layer of polymer composite material. The surface of the toggle plate 52 is plated with a polymer composite material layer, so that the surface of the structure is smooth, so that after it contacts with the drug particles, the polymer composite material layer can prevent the drug particles from adhering to the surface of the toggle plate 52 and causing clogging problems. When the arc touch plate 54 is made of resin material or PP material, it can be processed and manufactured by injection molding the toggle plate 52, the connecting seat 51 and the arc touch plate 54. When the arc touch plate 54 is made of metal material, it can be installed on the inner side of the toggle plate 52 by gluing or melting. No matter which material the arc touch plate 54 is made of, it can provide additional inertia force for the tail end of the toggle plate 52, and use the spacing range between the arc touch plate 54 and the toggle plate 52 as the swing torque to further amplify the centrifugal force generated in the swing of the tail end, thereby further improving the swing effect of the toggle plate 52, and prompting it to enter the excited state after the swing after being affected by the external force.

[0042] For details, please refer to the attached manual Figure 3-5 The connecting seat 51, the toggle plate 52, and the arc-shaped touch plate 54 are all made of elastic material, and the toggle plate 52 is a sheet-like structure as a whole.

[0043] The specific implementation method is as follows: the toggle plate 52 is in a sheet-like structure as a whole, so that when it is subjected to external force, the structure itself is prone to inertial swing, thereby colliding and contacting the drug particles inside the sieve hole 3 and the conical hole 4, and utilizing its own reciprocating swing effect to shake out and flexibly screen them, thereby further improving its screening rate.

[0044] For details, please refer to the attached manual Figure 6-7 The sieve holes 3 and the tapered holes 4 cooperate to penetrate the interior of the sieve net 1 , and the vertical height of the tapered holes 4 occupies 90% to 95% of the total thickness of the inner wall of the sieve net 1 .

[0045] The specific implementation method is as follows: the height of the sieve hole 3 is much smaller than the vertical height of the conical hole 4, so that after the sieve hole 3 screens the drug particles, the drug particles can quickly enter the conical hole 4, and the conical hole 4 is designed to gradually expand outward so that the internal volume for the drug particles is gradually increased, thereby improving the screening speed of the drug particles and avoiding the problem of sticking and clogging of a large number of particles during the screening process.

[0046] Working principle of the present invention:

[0047] The first step: First, the operator assembles the various components of the device normally, and then uses the device normally, and ensures that the upper and lower ends of the screening net 1 are respectively fastened with the sealing cover 7 and the bottom support box 8, and at the same time, the contact positions of the sealing cover 7 and the bottom support box 8 with the screening net 1 are in a sealed state.

[0048] Step 2: First, the operator holds the handles 2 on both sides of the sieve net 1 and performs a reciprocating sieving action in a horizontal range. At this time, the drug particles on the surface of the sieve net 1 will pass through the sieve holes 3 to complete the preliminary screening process, and then the drug particles after passing through the sieve holes 3 will gradually fall into the inside of the conical hole 4. At the same time, when the operator shakes the sieve net 1 horizontally, it will stimulate the toggle plate 52 in the inner wall of the conical hole 4 to swing synchronously. (The toggle plate 52 is a sheet-like structure as a whole. Therefore, when it is subjected to external force, it will swing its bottom end and its middle position through inertia. At the same time, the deformation notch 53 opened on its inner side will assist it to swing. The deformation during the swinging provides further auxiliary effect for its reciprocating swinging), so during the swinging process of the toggle plate 52, it will collide with the drug particles in a tilted posture in real time, and the direction of the tilted collision is always perpendicular to the surface of the toggle plate 52 and points obliquely downward, thereby always providing an oblique downward force on the drug particles to assist them in rapid screening. When the drug particles enter the conical hole 4, the conical hole 4 gradually expands outward, so that the internal volume for the drug particles is gradually increased, thereby improving the screening speed of the drug particles. The collision contact effect of the toggle plate 52 on the drug particles and the conical hole 4 are combined. The expansion effect of the hole 4 can be combined to avoid the problem of a large number of particles sticking and clogging during the screening process. On the other hand, when the toggle plate 52 swings back and forth, when it swings outward, the arc-shaped touch plate 54 on one side of the bottom end of the toggle plate 52 will contact the inner wall of the conical hole 4, and produce a high-frequency and low-amplitude collision, and the vibration generated by the collision is gradually transmitted to the entire toggle plate 52 through the arc-shaped touch plate 54. Then, the toggle plate 52 swings back and forth with a high-frequency and low-amplitude vibration posture. Therefore, when the toggle plate 52 collides with the drug particles during the swinging process, the toggle plate 52 will contact the drug particles in the vibration posture after the collision. The drug particles are in contact with each other, thereby transmitting the vibration to the drug particles at the moment of collision. Therefore, the collision between the two is a non-rigid collision, and there is vibration flexibility between the two, thereby achieving a flexible screening effect, and further assisting in rapid screening between drug particles. When the vibration is transmitted to the inside of the drug particles, the drug particles will present a high-frequency jitter state, thereby further avoiding sticking and clogging between the drug particles, and under the continuous contact between the toggle plate 52 and the drug particles, the purpose of flexible contact and rapid screening is achieved. Finally, the device completes the working process of flexible screening of drug particles.

[0049] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
