Description

Technical Field

[0001] The present invention relates to the technical field of preparation devices, and more particularly to an automatic preparation device for Chinese medicine application. Background Art

[0002] In traditional Chinese medicine patch treatment, the method is to grind the Chinese medicine raw materials into powder, then add auxiliary materials such as sesame oil, honey, alcohol, vinegar, etc. in proportion and mix and stir to form a paste, then grab a certain amount by hand and make pills by manually rolling them, and finally place the manually prepared pills in an empty patch.

[0003] Traditional manual pill-making methods suffer from low efficiency, high labor intensity, and slow pill-making speeds. To address this problem, a variety of pill-making devices have been developed on the market to improve production efficiency and reduce the complexity of manual operations. For example, existing patent CN214129492U discloses a simple pill-making device for Chinese medicine patches, which includes an operating plate, a forming hole, and a pressure rod. During use, medical staff only need to place a softer ointment on the operating plate, hold the pressure rod and apply pressure from top to bottom, so that the medicinal material is squeezed through the forming hole into a pill, thereby achieving rapid pill formation and avoiding the inefficiency of traditional manual pill-making.

[0004] However, during actual use, the inventors discovered that the device still has certain limitations. Although the pill forming speed has been improved, the pills still need to be manually picked up from the device and placed into the empty patch. Due to the high viscosity and strong adhesion of the paste-like pills, some pills may adhere to the bottom of the support frame during the picking process, making it difficult to completely remove the pills and causing contamination to the bottom of the support frame. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automatic preparation device for Chinese medicine patches, which can automatically press ointments into patches, thereby improving work efficiency and not easily causing pollution to the preparation platform.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The automatic preparation device for Chinese medicine patch includes a shell, a pressing mechanism, a preparation platform and a control unit. The shell is installed on the preparation platform and is used to accommodate Chinese medicine ointment. The pressing mechanism is arranged in the shell and is used to press the ointment into the shell in a quantitative manner. The control unit is electrically connected to the pressing mechanism and the preparation platform respectively to control the entire preparation process.

[0008] As a further improvement of the above technical solution:

[0009] The press mechanism comprises a rotating rod, a pressure rod, and a drive assembly for driving the rotating rod. The rotating rod is rotatably mounted within a housing having a through-hole extending therethrough. One end of the pressure rod is telescopically mounted on the rotating rod and threadedly connected thereto, while the other end is telescopically mounted on the housing and can pass through the through-hole from top to bottom. The housing has a slide groove along the direction in which the pressure rod extends and retracts, and the pressure rod has a slider that slides into the slide groove. The drive assembly is mounted above the housing and comprises a first gear, a rack, and a pulling member for pulling the rack. The first gear is mounted at the top of the rotating rod and fixedly connected thereto, meshing with the rack. The rack has a strip groove, and the pulling member comprises a disk, a first motor for driving the disk, and an eccentric shaft mounted on the disk, which slides into the strip groove. The housing has a guide rail along the direction in which the rack moves, and the rack has an insert block that slides into the guide rail. The strip groove is perpendicular to the guide rail and spans the entire length of the disk.

[0010] The guide rail is T-shaped. The rotating rod is provided with spiral blades. The top wall of the housing is provided with an air pipe, which is coiled into a circle and has air outlet holes distributed throughout the pipe body.

[0011] The preparation platform includes a base plate, a driven wheel, a driving wheel and a second motor for driving the driving wheel to rotate, and the driven wheel is engaged with the driving wheel; the driven wheel is provided with a plurality of application grooves, and the plurality of application grooves are evenly distributed around the center of the driven wheel; after the driven wheel rotates, the forming hole of the shell is aligned with one of the application grooves.

[0012] The at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0013] The combination of a pressing mechanism, a preparation platform, and a control unit allows for automatic compression of ointments into patches. The control unit controls the pressing mechanism to squeeze the ointment, allowing it to fall through the forming hole into the empty patch on the preparation platform. This not only improves work efficiency but also reduces contamination of the preparation platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the technical solution of the present invention is further described in detail in a non-limiting manner in conjunction with the accompanying drawings and specific embodiments.

[0026] In view of the drawback of low efficiency of making Chinese medicine patches using simple pill making devices in the existing medicine patches in the prior art. After careful analysis, the inventors found that the reason for the above technical problems is mainly that before the medicine is pushed from top to bottom through the forming holes by the pressure rod to make pills, several forming holes on the operating panel need to be filled with medicine. Moreover, after the pills are made, they still need to be picked up from the device manually and placed in the empty patch. Although there is no need to make pills by manual pill rolling and the staff's hands do not need to touch the medicine, the work efficiency is low. Based on the above analysis, the inventors designed an automatic preparation device for Chinese medicine patches, which can automatically press the ointment into a patch, which not only improves work efficiency but also is not easy to cause pollution to the preparation platform.

[0027] Example 1:

[0028] like Figures 1 to 4 As shown, a Chinese medicine patch preparation auxiliary device includes a housing 1, a pressing mechanism 2, a preparation platform 3, and a control unit 4. The housing 1 is mounted on the preparation platform 3 and is used to accommodate the Chinese medicine ointment. The pressing mechanism 2 is disposed within the housing 1 and is used to press a fixed amount of ointment into the housing 1. The control unit 4 is electrically connected to the pressing mechanism 2 and the preparation platform 3, respectively, to control the entire preparation process.

[0029] The pressing mechanism 2 comprises a rotating rod 21, a pressing rod 22, and a drive assembly 23 for driving the rotating rod 21. The rotating rod 21 is rotatably mounted within the housing 1, which is provided with a forming hole 11 extending therethrough. The pressing rod 22 has one end that is telescopically mounted on the rotating rod 21 and threaded therewith, while the other end is telescopically mounted on the housing 1 and can pass through the forming hole 11 from top to bottom. The housing 1 has a chute 12 along the direction of the pressing rod 22's extension and contraction. The pressing rod 22 has a slider that slides into the chute 12. Clockwise rotation of the rotating rod 21 drives the pressing rod 22 downward, extruding the medicinal material through the forming hole 11 into pills. Counterclockwise rotation of the rotating rod 21 drives the pressing rod 22 upward, disengaging the rotating rod 21 from the forming hole 11. This creates a space between the bottom of the housing 1 and the pressing rod 22, allowing the Chinese medicinal paste to be squeezed into the space between the bottom of the housing 1 and the pressing rod 22, awaiting the next pill extrusion.

[0030] Among them, the rotating rod 21 is provided with a spiral blade 5. The inner top wall of the shell 1 is provided with an air pipe 6, which is coiled into a circle and the body of the air pipe 6 is evenly distributed with air outlet holes 61. The inner wall of the shell 1 is covered with a layer of PTFE coating to reduce the ointment sticking to the inner wall of the shell 1. The shell 1 is provided with a water inlet pipe, which is connected to the air pipe 6 through a three-way valve. When the ointment lacks moisture and is not easy to stir and squeeze, the ointment can be replenished with moisture through the water inlet pipe, which is conducive to the ointment being squeezed into pills through the forming hole 11. The rotation of the rotating rod 21 can not only drive the pressure rod 22 to move up and down, but also enable the spiral blade 5 to stir spirally, that is, the spiral stirring has a shearing effect on the paste-like medicinal material, which can reduce the surface viscosity of the paste-like medicinal material and further promote flow; at the same time, the spiral blade 5 will generate axial thrust when rotating, forcing the paste to the forming hole 11, significantly improving the falling efficiency. The air flow in the air pipe 6 blows vertically from the top wall of the shell 1 to the bottom wall of the shell 1, generating downward pressure on the medicine, combined with the axial thrust generated by the rotation of the spiral blade 5; ensuring that when the rotating rod 21 is lifted, the medicine falls onto the top of the forming hole 11, and the medicine is squeezed into pills through the forming hole 11.

[0031] The driving assembly 23 is mounted above the housing 1 and includes a first gear 24, a rack 25, and a pulling member 26 for pulling the rack 25. The first gear 24 is disposed at the top of the rotating rod 21 and is fixedly connected thereto. The first gear 24 is engaged with the rack 25. The rack 25 is provided with a strip groove 27. The pulling member 26 includes a disc 28, a first motor 20 for driving the disc 28 to rotate, and an eccentric shaft 29 disposed on the disc 28. The eccentric shaft 29 is slidably embedded in the strip groove 27. The housing 1 is provided with a guide rail 13 along the direction of movement of the rack 25. The rack 25 is provided with an embedded block. The embedded block is slidably embedded in the guide rail 13. The strip groove 27 is disposed perpendicular to the guide rail 13 and spans the entire disc 28. The rack 25 can slide on the guide rail 13 and is less likely to get stuck. The guide rail 13 is T-shaped. The first motor 20 rotates the disc 28, causing the eccentric shaft 29 on the disc 28 to rotate around the center of the disc 28, pulling the rack 25 to slide within the guide rail 13. The rack 25 meshes with the first gear 24, causing the first gear 24 to rotate clockwise or counterclockwise. When the disc 28 rotates half a circle, the eccentric shaft 29 pulls the rack 25 to the left, causing the first gear 24 to rotate counterclockwise, driving the pressure rod 22 to move upward, creating a space between the bottom of the housing 1 and the pressure rod 22 for the Chinese medicinal ointment to flow in and wait for extrusion into pills. When the disc 28 rotates the other half a circle, the eccentric shaft 29 pulls the rack 25 to the right, causing the first gear 24 to rotate clockwise, driving the pressure rod 22 downward, and the medicinal material is extruded into pills through the forming hole 11. Each rotation of the disc 28 not only drives the rotating rod 21 to rotate, but also switches the first gear 24 between clockwise and counterclockwise rotation, thereby switching the pressure rod 22 between downward extrusion and upward lifting. The driving component 23 is combined with the spiral blade 5, and the forward and reverse rotations are alternated to alternate the direction of the shear force of the spiral blade 5, thereby preventing the ointment from forming a one-way adhesion layer on the spiral blade 5 or the wall of the shell 1, that is, the ointment is squeezed in the reverse direction, which may loosen the deposits originally stuck in the spiral gap or the forming hole 11; pushing forward again may enhance the overall fluidity, ensuring that when the rotating rod 21 is lifted, the medicine falls above the forming hole 11, and the medicine is squeezed into pills through the forming hole 11.

[0032] To prevent the ointment near the forming hole 11 from being pushed back when the spiral blades 5 reverse, air is introduced into the housing 1 during the rotation of the spiral blades 5. Air in the air pipe 6 blows vertically from the top wall of the housing 1 to the bottom wall of the housing 1, exerting downward pressure on the ointment. An exhaust hole is provided on the side of the housing 1 to prevent excessive pressure inside the housing 1.

[0033] The drive assembly 23 can also be used to keep the amount of each pill basically consistent. The amount of medicine in the pill depends on the distance between the inner bottom wall of the shell 1 and the bottom of the pressure rod 22, that is, the distance between the center of the disc 28 and the center of the eccentric shaft 29. The larger the distance, the higher the pressure rod 22 is lifted. The larger the distance between the inner bottom wall of the shell 1 and the bottom of the pressure rod 22, the more ointment enters the upper part of the forming hole 11. It can be seen that when the disc 28 of the drive assembly 23 rotates one circle, the amount of medicine squeezed into the empty patch is basically the same. It is worth noting that the pills do not have to be spherical after molding. The finished pills will eventually fill the retaining ring of the empty patch. Therefore, it is only necessary to ensure that the volume of the molded pills is controlled within a certain range.

[0034] Preparation platform 3 includes a base plate 31, a driven wheel 32, a driving wheel 33, and a second motor 34 for driving driving wheel 33. Driven wheel 32 is meshed with driving wheel 33. Driven wheel 32 is provided with multiple application slots 35, evenly distributed around the center of driven wheel 32. After driven wheel 32 rotates, molded hole 11 of housing 1 aligns with one of application slots 35. Control unit 4 includes a PLC controller and a contact sensor. The PLC controller is connected to the contact sensor, which is respectively arranged on the inner wall of guide rail 13 and preparation platform 3. The contact sensor is used to detect the signal when rack 25 reaches the specified position and transmit the signal to the PLC controller. It is also used to detect the signal when driven wheel 32 rotates to the specified position and transmit the signal to the PLC controller.

[0035] The PLC controller is connected to a transformer, which converts AC power into DC power to provide power for the motors, controllers, and sensors. The PLC controller is used to control the rotation of the first motor 20 and the second motor 34. The stop button is connected to the PLC controller input interface X12 and is used to disconnect the circuit in an emergency, stopping the first motor 20 and the second motor 34. The start button is connected to the input interface X11 and is used to start the PLC controller. The contact sensor is connected to the input interfaces X13, X14, and X15 and is used to transmit signals to the PLC controller. The PLC controller output interface Q2 is connected to the first motor 20 for controlling the first motor 20, and the PLC controller output interface Q1 is connected to the second motor 34 for controlling the second motor 34.

[0036] The working process of the control unit 4 is as follows:

[0037] (1) Press the start button, the PLC controller X11 contact is energized, and the automatic control program is started;

[0038] (2) Press the stop button, the PLC controller X12 contact is energized, and the automatic control program ends;

[0039] (3) Automatic control cycle program:

[0040] When the PLC controller Q2 is powered, the first motor 20 rotates to drive the rotating rod 21 to rotate, and the pressure rod 22 moves upward. When the pressure rod 22 is retracted into place, the contact sensor powers on the PLC controller, the PLC controller Q2 is powered off, and the first motor 20 stops rotating.

[0041] When the PLC controller Q1 is powered, the second motor 34 rotates to drive the driven wheel 32 to rotate. When the driven wheel 32 rotates to the right position, the contact sensor powers the PLC controller, the PLC controller Q1 is powered off, and the second motor 34 stops rotating.

[0042] The PLC controller Q2 is energized, the first motor 20 rotates to drive the rotating rod 21 to rotate, and the pressure rod 22 moves downward. When the pressure rod 22 is squeezed into place, the contact sensor powers on the PLC controller, the PLC controller Q2 is powered off, and the first motor 20 stops rotating. After 5 seconds, the first motor 20 rotates again to drive the rotating rod 21 to rotate, and the pressure rod 22 moves upward. When the pressure rod 22 is retracted into place, the contact sensor powers on the PLC controller, the PLC controller Q2 is powered off, and the first motor 20 stops rotating.

[0043] Example 2:

[0044] like Figure 5 and Figure 6 As shown, the difference between Example 2 and Example 1 is that the drive assembly 23 is a third motor. The PLC controller is connected to a transformer, which converts AC power into DC power to provide power for the motor, controller, and sensor. The PLC controller is used to control the rotation of the third motor and the second motor 34. The stop button is connected to the PLC controller input interface X12 and is used to disconnect the circuit in an emergency, stopping the third motor and the second motor 34. The start button is connected to the input interface X11 and is used to start the PLC controller. The third motor is an asynchronous motor with forward and reverse rotation functions. The PLC controller output interface Q2 is connected to the third motor via an intermediate relay KMF to control the switching between forward and reverse rotation of the third motor.

[0045] The working process of the control unit 4 is as follows:

[0046] (1) Press the start button, the PLC controller X11 contact is energized, and the automatic control program is started;

[0047] (2) Press the stop button, the PLC controller X12 contact is energized, and the automatic control program ends;

[0048] (3) Automatic control cycle program:

[0049] When the PLC controller Q2 is powered, the third motor reverses, driving the rotating rod 21 to rotate counterclockwise, and the pressure rod 22 moves upward. When the pressure rod 22 is retracted into place, the contact sensor powers up the PLC controller, the PLC controller Q2 is powered off, and the third motor stops rotating.

[0050] When the PLC controller Q1 is powered, the second motor 34 rotates, driving the driven wheel 32 to rotate. When the driven wheel 32 rotates to the right position, the contact sensor powers the PLC controller, the PLC controller Q1 is powered off, and the second motor 34 stops rotating.

[0051] When PLC controller Q3 is powered, the third motor rotates forward, driving rotating rod 21 to rotate clockwise and pressing rod 22 to move downward. Once pressing rod 22 is in place, the contact sensor powers the PLC controller again, de-energizing PLC controller Q3 and stopping the third motor. Five seconds later, PLC controller Q2 is powered, causing the third motor to rotate in the reverse direction. The third motor rotates again, driving rotating rod 21 and pressing rod 22 upward. Once pressing rod 22 is fully retracted, the contact sensor powers the PLC controller again, de-energizing PLC controller Q2 and stopping the third motor.

[0052] Example 3:

[0053] like Figures 7 to 8 As shown, the difference between Example 3 and Example 1 lies in the pressing mechanism 2 and the drive assembly 23, and the drive assembly 23 is a fourth motor. The pressing mechanism 2 includes a rotating rod 71, a second spiral blade 72 and a feeding turbine 73. The fourth motor is used to drive the rotating rod 71 to rotate. The rotating rod 71 is rotatably installed in the housing 1 and one end is connected to the fourth motor, and the other end is fixedly connected to the feeding turbine 73. The second spiral blade 72 is provided on the rod body of the rotating rod 71. A barrel is vertically installed below the forming hole 11, and the feeding turbine 73 is located in the barrel and is coaxially arranged with the barrel.

[0054] During use, the medicinal material is poured into the housing 1. After the fourth motor is turned on, it drives the feed worm 73 to rotate, and at the same time drives the second spiral blade 72 to rotate, stirring and shearing the medicinal material in the housing 1. The axial thrust generated by the rotation of the second spiral blade 72 pushes the medicinal material into the barrel, thereby continuously introducing the medicinal material in the housing 1 into the gap between the barrel and the feed worm, and continuously squeezing the medicinal material and forcing it out of the bottom of the barrel and falling into the empty patch. Finally, when the driven wheel 32 rotates, the housing 1 and the driven wheel 32 generate relative motion, and the housing 1 cuts the medicinal material, leaving it in the empty patch.

[0055] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the scope of protection of the present invention.
