Description

Technical Field

[0001] This invention relates to the medical field, and in particular to a method for processing and forming traditional Chinese medicine pills. Background Technology

[0002] Traditional Chinese medicine pills are one type of Chinese medicine. There are two processing methods for traditional Chinese medicine pills: molding and coating. The coating method refers to a pill-making method where fine drug powder and a wetting agent or binder are alternately sprinkled and moistened in suitable tumbling equipment, causing the pills to gradually increase in size. Its main process flow is as follows: drugs and excipients → film formation → pill formation → coating → drying → pill selection → polishing (coating) → quality inspection → packaging. However, the existing coating method for traditional Chinese medicine pill making still has the following problems in the drying and pill selection process:

[0003] 1. The pills produced by the pan-processing method require the continuous addition of powder and water during the production process. The repeated process is extensive, and the produced pills need to be taken out immediately for drying and sorting. The accumulated pills are prone to deformation, making it impossible to guarantee the spherical shape of the pills and affecting their quality.

[0004] 2. During the pill-making process, a certain amount of powder needs to be sprinkled out multiple times. The powder is prone to spillage during the process of adding it to the equipment, which affects the quality of the pills. The powder tends to accumulate when it is sprinkled out, which leads to uneven pill formation.

[0005] 3. Water needs to be sprayed during the pill-making process. Too much liquid should not be sprayed, as it may affect the pill's formation. Too little liquid will prevent the powder from adhering properly. Furthermore, the liquid dripping from the spraying device after it sprays out will also affect the pill's formation. Summary of the Invention

[0006] To solve the above problems, the present invention adopts the following technical solution: a method for processing and forming traditional Chinese medicine pills, wherein the specific processing and forming steps of the traditional Chinese medicine pills are as follows:

[0007] S1. Sprinkle the powder into the turning drum, spray water into it while the drum is rotating, so that the powder becomes wet small particles. Add a small amount of fine powder and continue rolling for a certain period of time to make the small particles firm and dense. Then spray water and sprinkle powder again.

[0008] S2. Repeat this process, adding an appropriate amount of powder, and rolling the roller to obtain loose lumps. Gently knead the lumps with your hands to break up the larger ones. Continue this process to form pills.

[0009] S3. Continue to alternately add a certain amount of powder and water to the turning roller of the pellet mold obtained in step S2, and keep turning the turning roller back and forth to enhance the hardness and roundness of the pellets until the pellets gradually increase in size and meet the requirements.

[0010] S4. Use a suitable sieve to screen the pills to make them uniform and consistent. If the pills are too small, enlarge them. If they are too large or deformed, separate them and process them appropriately. Cover the pills to make the surface dense, smooth and uniform in color, and then dry them.

[0011] The above-mentioned processing and forming steps of traditional Chinese medicine pills require the cooperation of a turning roller, a fixed support, a telescopic rod, a spraying device, a vibrating screen assembly, a clamping block, a sleeve, and a cam.

[0019] Preferably, the lower end of the first arc-shaped plate is provided with two support plates, which are located on both sides of the first ball block. The lower ends of the two support plates are fixedly connected by a C-shaped rod. The ball groove provided at the upper end of the fixed bracket protrudes outward, and the first ball block is engaged in the ball groove. The two sides of the upper end of the fixed bracket are inclined downward.

[0021] In addition, the present invention also provides a method for processing and shaping traditional Chinese medicine pills, the specific preparation method of which is as follows:

[0022] S1. Sprinkle the powder into the turning drum, spray water into it while the drum is rotating, so that the powder becomes small wet particles. Add a small amount of fine powder and continue rolling for a certain period of time to make the small particles firm and dense. Then spray water and sprinkle powder again.

[0023] S2. Repeat this process, adding an appropriate amount of powder and rolling the roller to obtain loose lumps. Gently knead the lumps with your hands to break up the larger ones. Continue this process to form pills.

[0024] S3. Continue to alternately add a certain amount of powder and water to the turning roller of the pellet mold obtained in step S2, and keep turning the turning roller back and forth to enhance the hardness and roundness of the pellets until the pellets gradually increase in size and meet the requirements.

[0025] S4. Use a suitable sieve to screen the pills to make them uniform in size. If the pills are too small, enlarge them. If they are too large or deformed, separate them and process them appropriately. Cover the pills to make their surface dense, smooth, and uniform in color, and then dry them.

[0026] The beneficial effects of the present invention are as follows: 1. The present invention uses a pan-coating method to make pills. During the pill-making process, the amount of water sprayed is controlled by a spraying device. The rotatable vibrating screen assembly facilitates the even and quantitative spraying of the medicine powder.

A spraying device is used to control the spraying of liquid, and a drip-proof cover is used to prevent the dripping liquid from scattering the pills.

[0028] 3. In this invention, the combination of the powder-sprinkling box and the powder-sprinkling net facilitates the uniform addition of a fixed amount of medicinal powder during the pill-making process, thereby ensuring uniform pill formation and preventing pills of different sizes.

[0043] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0044] See Figure 1 , Figure 2 and Figure 3 A method for processing and shaping traditional Chinese medicine pills, the specific processing steps of traditional Chinese medicine pills are as follows:

[0045] S1. Sprinkle the powder into the turning drum 1. Spray water into the turning drum 1 while it is rotating so that the powder becomes wet small particles. Add a small amount of fine powder and continue rolling for a certain period of time to make the small particles firm and dense. Then spray water and sprinkle powder again.

[0046] S2. Repeat this process, adding an appropriate amount of powder, and rolling the roller 1 to obtain loose lumps. Gently knead the lumps with your hands to break up the larger ones. Continue this process to form pills.

[0047] S3. Continue to alternately add a certain amount of powder and water to the turning roller 1 of the pellet mold obtained in step S2, and keep turning the turning roller 1 back and forth to enhance the hardness and roundness of the pellets until the pellets gradually increase in size and meet the requirements.

[0048] S4. Use a suitable sieve to screen the pills to make them uniform and consistent. If the pills are too small, enlarge them. If they are too large or deformed, separate them and process them appropriately. Cover the pills to make the surface dense, smooth and uniform in color, and then dry them.

[0049] The above-mentioned processing and forming steps of traditional Chinese medicine pills require the cooperation of a turning roller 1, a fixed bracket 22, a telescopic rod 35, a spraying device 4, a vibrating screen assembly 5, a clamping block 6, a sleeve 7, and a cam 8. Among them, the upper end of the tilting roller 1 is provided with a feed inlet 11, and the lower end of the tilting roller 1 is provided with a discharge outlet 12. Two bearing rings 13 are sleeved on the outer side of the tilting roller 1. The medicine powder is added and water is sprayed through the feed inlet 11, and the formed pills are taken out through the discharge outlet 12. The bearing rings 13 facilitate the rotation of the tilting roller 1, thereby facilitating the gradual enlargement of the pills produced by the pan-forming method.

[0050] See Figure 5 , Figure 6 and Figure 7 A first arc plate 2 is provided at the lower end of the outer side of the bearing ring 13 near the discharge port 12. A first ball block 21 fixed at the lower end of the first arc plate 2 is engaged in the ball groove 23 opened at the upper end of the fixed bracket 22. The ball groove 23 protrudes outward, and the two sides of the upper end of the fixed bracket 22 are inclined downward to facilitate the deflection of the first arc plate 2.

[0051] A semi-circular movable hole 26 is provided at the lower end of the ball groove 23. A C-shaped rod 25 passes through the movable hole 26. Support plates 24 are fixed at the two upper ends of the C-shaped rod 25. The support plates 24 are located on both sides of the first ball block 21. The support plates 24 abut against the lower end of the first arc plate 2. When the first arc plate 2 deflects, it drives the C-shaped rod 25 to slide in the movable hole 26, so that the two support plates 24 always abut against the lower end of the first arc plate 2, which facilitates the support of the first arc plate 2 and increases the stability of the tilting roller 1 when it tilts.

[0052] See Figure 3 , Figure 5 and Figure 8 A second arc-shaped plate 3 is provided at the lower outer end of the bearing ring 13 near the feed inlet 11. A ball cap 33 is fixed at the lower end of the second arc-shaped plate 3. The ball cap 33 is fitted onto the second ball block 34 fixed at the upper end of the telescopic rod 35. The upper end of the telescopic rod 35 is arc-shaped. Rollers 36 are provided on both sides of the lower end of the telescopic rod 35. The rollers 36 are slidably connected in the guide rail 37. The guide rail 37 is fixed to the lower side of the fixed bracket 22. The rollers 36 move along the guide rail 37 to facilitate the adjustment of the position of the telescopic rod 35, thereby facilitating the tilting of the tilting roller 1 by the extension and retraction of the telescopic rod 35.

[0053] The deflection of the first arc plate 2 and the second arc plate 3 facilitates adjustment when the tilting roller 1 is tilted, ensuring that the first arc plate 2 and the second arc plate 3 are always aligned with the bearing ring 13, thus not interfering with the rotation of the tilting roller 1. When the tilting roller 1 approaches horizontal, pelleting is performed. The prepared pellets are quickly removed by tilting the tilting roller 1, reducing the deformation caused by the accumulation of pellets and preventing the pellets from adhering to each other.

[0054] See Figure 3 , Figure 8 and Figure 9 The side end of the second arc plate 3 is fixed with a first L-shaped frame 31 and a second L-shaped frame 32. The rotating rod 46 hinged to the upper end of the first L-shaped frame 31 on the side end is fixed with a movable arm 45. A spraying device 4 is fixedly installed on the movable arm 45. The spraying device 4 is located at the upper end of the inner cavity of the turning drum 1. Water can be sprayed during the pelleting process through the spraying device 4.

[0055] The spray device 4 consists of a trumpet-shaped nozzle and a cylindrical fixed tube. A movable frame 44 is fitted on the outside of the fixed tube of the spray device 4 (the vertical rod of the movable frame 44 is divided into two rotatable sections in the middle, which facilitates the rotation of the lower end of the movable frame 44). A drip-proof cover 42 is provided in the middle of the support ring 43 fixed at the lower end of the movable frame 44, which facilitates the disassembly and installation of the drip-proof cover 42. The upper end of the opening of the drip-proof cover 42 is aligned with the lower end of the nozzle of the spray device 4 to prevent the dripping liquid from scattering the pills when water is not needed, thus affecting the formation of the pills. Rotating the lower end of the movable frame 44 moves the drip-proof cover 42 away from the lower end of the spray device 4, thereby facilitating the spray device 4 to spray water and facilitating the adhesion of the powder to the pills so that they can roll and increase in size.

[0056] The other end of the fixed tube of the spray device 4 is connected to a hose 41. The hose 41 is connected to the water outlet device set on the first L-shaped frame 31. The water output and water output time of the spray device 4 are controlled by a switch. The upper end of the fixed tube of the spray device 4 is snapped into the C-shaped notch at the end of the movable arm 45, which facilitates the support and fixation of the spray device 4 by the movable arm 45. The hose 41 is wrapped around the movable arm 45. The rotating rod 46 fixed at the other end of the movable arm 45 is rotatably connected to the upper end face of the first L-shaped frame 31. The rotating rod 46 is snapped into the first L-shaped frame 31. By rotating the protrusion on the outside of the rotating rod 46, the movable arm 45 can be rotated together, which makes it easy to remove the spray device 4 from the inner cavity of the turning roller 1. The placement groove 47 opened on the side end of the rotating rod 46 is similar in shape to the fixed tube of the spray device 4. The spray device 4 can be removed from the end of the movable arm 45, which makes it easy to snap the spray device 4 into the placement groove 47 for storage.

[0057] See Figure 5 , Figure 6 , Figure 8 and Figure 9 The upper end of the second L-shaped frame 32 is fixed with a support 74. The other end of the connecting rod 72, which is hinged to the upper end of the support 74, is hinged with a sleeve 7. The middle of the connecting rod 72 is hinged in the groove opened at the upper end of the support 74 to facilitate the rotation of the connecting rod 72. Two opposing triangular blocks 73 are fixed on the side of the connecting rod 72 near the support 74. The triangular blocks 73 are located on both sides of the rotation axis of the connecting rod 72 near the support 74. The triangular blocks 73 abut against the upper end surface of the support 74, so as to limit the rotation angle of the connecting rod 72 by means of the triangular blocks 73.

[0058] See Figure 3 , Figure 4 , Figure 6 and Figure 9The other end of the connecting rod 72 is hinged to the upper end of the sleeve 7. A cam 8 is provided between the sleeve 7 and the connecting rod 72. A motor 81 is fixed on the support 74 in the middle of the cam 8, so that the cam 8 can be rotated by the motor 81. The side of the cam 8 abuts against the inclined moving rod 83. The moving rod 83 is I-shaped. The crossbar of the U-shaped rod 82 passes through the middle of the moving rod 83 to prevent the moving rod 83 from slipping off the U-shaped rod 82. The two ends of the U-shaped rod 82 are fixed on the support 74. A return spring 84 is wound around the rod of the moving rod 83 near the cam 8. The other end of the moving rod 83 abuts against the side of the sleeve 7.

[0059] The rotating cam 8 abuts against the end of the moving rod 83, which facilitates the moving rod 83 to move left and right on the U-shaped rod 82. Through the elastic force of the return spring 84 and the cooperation of the cam 8, the moving rod 83 can move back and forth left and right, which facilitates the sleeve 7 to deflect back and forth around the hinge.

[0060] See Figure 9 and Figure 10 The sleeve 7 is equipped with a vibrating screen assembly 5 at its end. The sleeve 7 is deflected by the cam 8, which facilitates the up and down vibration of the vibrating screen assembly 5 and makes it easy to evenly sprinkle the powder into the turning drum 1.

[0061] The vibrating screen assembly 5 includes a powder-spreading box 51 and a powder-spreading net 53. The powder-spreading box 51 is semi-ellipsoidal. Multiple arc-shaped rods 52 are provided on the fixed columns 54 on both sides of the powder-spreading box 51. A powder-spreading net 53 is fixedly installed between every two arc-shaped rods 52. The arc of the arc-shaped rods 52 is the same as that of the powder-spreading box 51. Arc-shaped rods 52 are provided on the side near the upper end of the powder-spreading box 51, so that the powder-spreading net 53 can be fixed to the upper end of the powder-spreading box 51 through the arc-shaped rods 52. Fixed columns 54 are fixed in the notches opened at both ends of the powder-spreading box 51. Multiple arc-shaped rods 52 are equidistantly connected in the semi-circular openings on the sides of the two fixed columns 54, so that the arc-shaped rods 52 can drive the powder-spreading net 53 to rotate, thereby facilitating the opening and closing of the powder-spreading box 51.

[0062] A fixing rod 55 is fixed to the end of the powder box 51 near the feed inlet 11. The outer end of the fixing post 54 near the feed inlet 11 is engaged in the circular groove 56 opened at the side end of the fixing rod 55. The circular groove 56 is fitted on the outer side of the end of the arc rod 52 to avoid affecting the rotation of the arc rod 52.

[0063] A short rod 57 is slidably connected inside the through hole 58 of the fixed rod 55. The length of the short rod 57 is longer than the outer diameter of the fixed rod 55. The middle outer diameter of the short rod 57 is larger than the outer diameters of the two sides of the short rod 57 to prevent the short rod 57 from slipping out of the through hole 58. The inner diameter of the openings at both ends of the through hole 58 is the same as the outer diameters of the two sides of the short rod 57. The short rod 57 is slidably connected inside the through hole 58. A sleeve 7 is fitted on the outside of the fixed rod 55. The short rod 57 is engaged in the arc-shaped hole 71 opened on the outside of the sleeve 7. The width of the arc-shaped hole 71 is the same as the width of the two ends of the short rod 57. The short rod 57 located outside the fixed rod 55 is slidably connected inside the arc-shaped hole 71.

[0064] When the short rod 57 is moved so that only one end of the short rod 57 is outside the arc-shaped hole 71, the short rod 57 is rotated half a turn along the arc-shaped hole 71, causing the powder-spreading box 51 to rotate together, so that the powder-spreading net 53 is located at the lower end, which facilitates the sprinkling of the powder. (When the powder-spreading net 53 is located at the upper end, the rotating connecting rod 72 causes the powder-spreading box 51 to move outward together, which facilitates the loading of a measured amount of powder into the powder-spreading box 51). The short rod 57 is moved so that both ends of the short rod 57 protrude outside the fixed rod 55. At this time, both ends of the short rod 57 are engaged in the arc-shaped hole 71, which facilitates fixing the direction of the powder-spreading box 51.

[0065] See Figure 10 , Figure 11 and Figure 12 A locking block 6 is hinged to the outer side of the arc-shaped rod 52 near the side of the powder-spreading box 51. The locking block 6 is locked onto the T-shaped column 62 set on the side of the powder-spreading box 51, which makes it easy to fix the powder-spreading net 53 to the upper end of the powder-spreading box 51, and prevent the powder-spreading net 53 from separating from the powder-spreading box 51 when the vibrating screen assembly 5 vibrates, thus losing the function of evenly spreading the powder.

[0066] A protrusion 67 is fixed in the middle of the outer side of the powder box 51. A compression spring 66 is fixed at the bottom of the moving groove 68 opened at the end of the protrusion 67. The other end of the compression spring 66 is fixed to the end of the T-shaped column 62, so that the T-shaped column 62 can move in the moving groove 68. A slot 63 is opened on both sides of the T-shaped column 62 located in the inner cavity of the moving groove 68. A raised V-shaped block 64 is fixed in the middle of the slot 63. A gap is provided between the side wall of the V-shaped block 64 and the slot 63. A locking rod 65 is fixed at the bottom of the moving groove 68. The locking rod 65 is L-shaped, and the protrusion of the locking rod 65 is slidably connected between the V-shaped block 64 and the side wall of the slot 63. The locking rod 65 is elastic, and the path of the gap is similar to the outer edge of the V-shaped block 64, so that the locking rod 65 can move along the gap.

[0067] When the T-shaped post 62 is pressed against the bottom of the moving groove 68, the locking rod 65 moves along the locking groove 63 until the end of the locking rod 65 is engaged in the groove of the V-shaped block 64, which facilitates the fixing of the T-shaped post 62. The outer diameter of the outer protrusion of the T-shaped post 62 is larger than the inner diameter of the hook of the locking block 6. The locking block 6 is hinged to the outer side of the arc rod 52 near the side of the powder-spreading box 51 by the round block 61. At this time, the T-shaped post 62 fixes the hook of the locking block 6, which facilitates the fixing of the powder-spreading net 53 and the powder-spreading box 51 when the vibrating screen assembly 5 vibrates. Pressing the T-shaped post 62 again causes the locking rod 65 to slide out of the groove of the V-shaped block 64. The elastic force of the compression spring 66 facilitates the pop-out of the T-shaped post 62, which facilitates the rotation of the locking block 6, thereby facilitating the opening of the powder-spreading net 53.

[0068] A ring is fitted around the outside of the protrusion 67. The ring and the powder box 51 are fixed by a limiting spring, which allows the ring to move around the outside of the protrusion 67. When the T-shaped post 62 is fixed in the moving groove 68 by the locking rod 65, the locking block 6 is pressed tightly between the ring and the T-shaped post 62 by the elastic force of the limiting spring. The inner side of the locking block 6 and the protrusion 67 are left with a certain distance, so that when the T-shaped post 62 is pressed again, the locking rod 65 can slide out from the groove of the V-shaped block 64.

[0069] Working principle: The telescopic rod 35 drives the second arc plate 3 to move together, which facilitates the change of the tilt angle of the tilting drum 1, thereby facilitating the pellet making and pellet removal of the tilting drum 1. The two support plates 24 connected by the C-shaped rod 25 abut against the outside of the first arc plate 2, which helps to ensure the stability of the tilting drum 1 when tilting. The first L-shaped frame 31 and the second L-shaped frame 32 fixed to the side end of the second arc plate 3 facilitate the installation of the spraying device 4 and the vibrating screen assembly 5 on the upper end of the inner cavity of the tilting drum 1, which facilitates water spraying and powdering during the pellet making process. The anti-drip cover 42 set at the lower end of the spraying device 4 helps to prevent liquid dripping from affecting the pellet forming. The end of the spraying device 4 is clamped on the moving arm 45. By rotating the rotating rod 46 clamped on the first L-shaped frame 31, it is easy to move the spraying device 4 out and in the inner cavity of the tilting drum 1.

[0070] The upper end of the main body powder-spreading box 51 of the vibrating screen assembly 5 is provided with a powder-spreading net 53 that can be opened by rotating an arc-shaped rod 52. A locking block 6 is hinged to the outside of the arc-shaped rod 52 and is engaged with a T-shaped post 62 on the outside of the powder-spreading box 51. Pressing the T-shaped post 62 facilitates the fixing and disassembly of the locking block 6, thereby facilitating the fixing and opening of the powder-spreading net 53. A sleeve 7 is sleeved on the outside of the fixing rod 55 fixed to the side of the powder-spreading box 51. A short rod 57 passing through the fixing rod 55 is slidably connected in the arc-shaped hole 71 opened on the outside of the sleeve 7. The short rod 57 facilitates the control of the rotation of the powder-spreading box 51 and the powder-spreading net 53, thereby facilitating the opening and closing of the powder-spreading net 53. For powder application and loading, a connecting rod 72 is hinged to the upper end of the sleeve 7. By rotating the connecting rod 72 outward, the vibrating screen assembly 5 can be easily moved out, and a fixed amount of powder can be loaded into the powder application box 51. By rotating the connecting rod 72 inward, and simultaneously rotating the short rod 57, the powder application box 51 can be closed and inverted to apply powder from the powder application net 53. A moving rod 83 is provided between the connecting rod 72 and the sleeve 7. The moving rod 83 can be moved left and right by the rotation of the cam 8 and the elasticity of the return spring 84, thereby pushing the sleeve 7 to deflect back and forth, thereby driving the vibrating screen assembly 5 to vibrate, so that the powder can be evenly applied into the turning drum 1.
