Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine preparation equipment technology, and more specifically, to a device and method for making compound pills of traditional Chinese medicine. Background Technology

[0002] Currently, the pill-making process for traditional Chinese medicine pills typically involves first extruding the kneaded herbal dough into strips, and then using two pill-making rollers to press and form pills. While this method addresses some of the shortcomings of manual kneading, its efficiency remains low, and the recovery of the herbal strips not involved in pill-making is inconvenient. In particular, the sticky parts are even more difficult to handle when they adhere to the pill-making rollers, leading to waste. Therefore, there is a need for a more efficient pill-making equipment for compound traditional Chinese medicine pills that can solve the problem of herbal dough recovery. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a device and method for making compound pills of traditional Chinese medicine, in view of the above-mentioned defects of the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A device for manufacturing compound pills of traditional Chinese medicine is constructed, comprising an inclined base plate, a first extrusion plate, a second extrusion plate, and a mounting bracket. The upper surface of the base plate has two processing areas. Push plates and electric push rods for driving the push plates are arranged on the four cardinal directions (north, south, east, and west) around the perimeter of each processing area. Multiple first semi-circular holes are provided in each processing area. An elastic membrane is sealed and covered at the opening of each semi-circular hole, and the elastic membrane is flush with the upper surface of the base plate. Multiple liquid inlet holes are provided on the inner wall of each semi-circular hole, and a supply valve communicating with the liquid inlet holes is provided on the base plate. The coolant includes a flow channel and a hydraulic unit for adjusting the coolant injection pressure. The mounting bracket is equipped with a rotating frame and a stepper motor that drives the rotating frame to rotate. The rotating frame is equipped with a first lifting unit that moves the first extrusion plate toward or away from the base plate, and a second lifting unit that moves the second extrusion plate toward or away from the base plate. Both the first and second extrusion plates are matched to the dimensions of the processing area. The first extrusion plate is a flat plate, and the lower surface of the second extrusion plate is provided with an extrusion head. The lower end of the extrusion head is provided with a second semi-circular hole that mates with the first semi-circular hole.

[0006] The traditional Chinese medicine compound pill making equipment of the present invention includes a mounting bracket comprising a support base fixedly connected to the base plate, a circular track and a slider slidably disposed on the track at the top of the support base; a stepper motor is disposed at the center of the track, and a rotating frame is disposed at the movable end of the stepper motor, the rotating frame being connected to the slider.

[0007] The traditional Chinese medicine compound pill making equipment of the present invention, wherein the first extrusion plate and the second extrusion plate are centrally symmetrically distributed along the rotation axis of the rotating frame.

[0008] The traditional Chinese medicine compound pill making equipment of the present invention includes a first lifting unit and a second lifting unit, each comprising a longitudinal lead screw disposed at the end of the rotating frame and a lead screw motor for driving the longitudinal lead screw; a fixed column is disposed on the back of the first extrusion plate and the second extrusion plate, and a guide sleeve is disposed on the rotating frame and sleeved on the fixed column; the fixed column is fixedly connected to the lead screw nut of the lead screw, and the guide sleeve is provided with a sliding groove corresponding to the lead screw nut.

[0009] The traditional Chinese medicine compound pill making equipment of the present invention includes a guide groove on the bottom plate for guiding the rolling pills, and a conveyor belt at the bottom of the guide groove. When the conveyor belt is running, the forward direction of the upper surface is opposite to the rolling direction of the pills.

[0010] The traditional Chinese medicine compound pill making equipment of the present invention includes a receiving belt on the edge of the bottom plate for receiving the pills that have passed through the guide groove.

[0011] The traditional Chinese medicine compound pill making equipment of the present invention has a base plate with an inclination angle of 10-15 degrees.

[0012] A method for preparing traditional Chinese medicine compound pills, applied to the aforementioned equipment for preparing traditional Chinese medicine compound pills, includes the following steps:

[0013] The two prepared Chinese medicine balls are placed into two processing areas respectively, and the four push plates on the periphery limit the periphery of the Chinese medicine balls. At this time, the hydraulic unit injects coolant into the first semi-circular hole through multiple liquid inlet holes and maintains the liquid level.

[0014] The stepper motor rotates so that the first extrusion plate is aligned with a processing area. Then, the first lifting unit drives the first extrusion plate to move down and extrude the Chinese medicine clump to the set thickness. After that, the first extrusion plate moves up and returns to its original position.

[0015] Four push plates alternately push the herbal medicine ball, causing it to move on the base plate and level its lower surface. At the same time, the stepper motor rotates so that the second extrusion plate is aligned with the processing area, while the first extrusion plate is aligned with another processing area and performs a leveling operation.

[0016] The second lifting unit drives the second extrusion plate downward. The extrusion head descends and squeezes the medicine mud in the corresponding position of the Chinese medicine ball into the first semi-circular hole. At the same time, the hydraulic unit draws out the liquid in the first semi-circular hole. The elastic membrane is deformed by the suction force and sticks tightly to the inner wall of the first semi-circular hole. The first semi-circular hole and the second semi-circular hole complete the matching extrusion pelleting operation.

[0017] The second lifting unit drives the second extrusion plate to move upward and reset. The hydraulic unit slowly injects liquid into the first semi-circular hole and pushes the elastic membrane. The elastic membrane gradually recovers its deformation and squeezes the pill out of the first semi-circular hole. The pill rolls down the bottom plate and is discharged.

[0018] The stepper motor rotates so that the second extrusion plate is aligned with another processing area and extrudes the herbal pellets. At the same time, four push plates move to extrude the remaining herbal pellets in the current processing area, so that the holes on the herbal pellets disappear and then the first extrusion plate performs a leveling operation.

[0019] The beneficial effects of this invention are as follows: Two prepared herbal medicine balls are placed into two processing areas respectively, and the four push plates on the periphery limit the movement of the herbal medicine balls. At this time, the hydraulic unit injects coolant into the first semi-circular hole through multiple inlet holes and maintains the liquid level; the stepper motor rotates so that the first extrusion plate is aligned with one processing area, and then the first lifting unit drives the first extrusion plate downward to extrude the herbal medicine balls to a set thickness, and then the first extrusion plate rises back to its original position; the four push plates alternately push the herbal medicine balls, causing them to move on the base plate and level the lower surface of the herbal medicine balls; at the same time, the stepper motor rotates so that the second extrusion plate is aligned with the processing area, and the first extrusion plate is aligned with the other processing area for leveling operation; the second lifting unit carries... The second extrusion plate moves downward, and the extrusion head moves downward to squeeze the corresponding part of the herbal paste into the first semi-circular hole. At the same time, the hydraulic unit draws the liquid out of the first semi-circular hole. The elastic membrane deforms under the suction force and adheres tightly to the inner wall of the first semi-circular hole. The first and second semi-circular holes complete the extrusion pelleting operation. The second lifting unit drives the second extrusion plate to move upward and reset. The hydraulic unit slowly introduces liquid into the first semi-circular hole and pushes the elastic membrane. The elastic membrane gradually recovers its deformation and squeezes the pellet out of the first semi-circular hole. The pellet rolls down the bottom plate for discharge. The stepper motor rotates so that the second extrusion plate is aligned with another processing area and performs extrusion pelleting operation. At the same time, the four push plates move to extrude the remaining herbal paste in the current processing area, so that the holes on the herbal paste disappear. Then, the first extrusion plate performs a leveling operation.

[0020] The novel pill-making equipment of this application allows for batch extrusion into pills in one processing area while the herbal clumps are being leveled. The two processing areas alternate, and the initially placed herbal clumps can undergo multiple extrusion operations, ensuring both efficiency and quality. Four push plates not only limit the position of the herbal clumps but also control the extrusion area and clamp the extruded herbal clumps. The coolant not only cools the pills and the base plate but also, in conjunction with the hydraulic unit, provides support to the elastic membrane during the leveling stage to prevent the herbal clumps from sinking into the first semi-circular hole. During the extrusion stage, the coolant pulls the elastic membrane to deform it and make it conform to the inner wall of the first semi-circular hole, ensuring smooth transition between leveling and extrusion. After pill formation, the coolant also pushes the pills out of the first semi-circular hole, and the inclined base plate causes the pills to roll and be discharged. Each extrusion and discharge operation ensures continuous processing. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0027] The preferred embodiment of the traditional Chinese medicine compound pill preparation equipment of the present invention, such as... Figure 1 As shown, see also Figure 2 and Figure 3 The system includes an inclined base plate 1, a first extrusion plate 2, a second extrusion plate 3, and a mounting bracket. The upper surface of the base plate 1 has two processing areas 10. Push plates 11 and electric push rods 12 for driving the push plates are located on the four sides of the processing areas 10. Multiple first semi-circular holes 13 are provided on the processing areas 10. An elastic membrane 14 is sealed and covered at the opening of each first semi-circular hole 13, and the elastic membrane 14 is flush with the upper surface of the base plate 1. Multiple liquid inlet holes 130 are provided on the inner wall of each first semi-circular hole 13. A cooling fluid supply system communicating with the multiple liquid inlet holes 130 is provided on the base plate 1. The flow channel 15 and the hydraulic unit 16 for adjusting the squeezing pressure of the coolant are provided; a rotating frame 40 and a stepper motor 41 for driving the rotating frame 40 to rotate are provided on the mounting bracket. The rotating frame 40 is provided with a first lifting unit 42 for moving the first extrusion plate 2 toward or away from the base plate 1 and a second lifting unit 43 for moving the second extrusion plate 3 toward or away from the base plate 1. The first extrusion plate 2 and the second extrusion plate 3 are both matched with the size of the processing area. The first extrusion plate 2 is a flat plate. The lower surface of the second extrusion plate 3 is provided with an extrusion head 30. The lower end of the extrusion head 30 is provided with a second semi-circular hole 31 that mates with the first semi-circular hole.

[0028] Two prepared herbal medicine balls are placed into two processing areas 10 respectively, and the four push plates 11 on the periphery limit the movement of the herbal medicine balls. At this time, the hydraulic unit 16 injects coolant into the first semi-circular hole 13 through multiple liquid inlet holes 130 and maintains the liquid level (so that the elastic membrane is in a flat or near-flat state). The stepper motor 41 rotates so that the first extrusion plate 2 is directly facing one of the processing areas 10. Then, the first lifting unit 42 drives the first extrusion plate 2 to move down and extrude the herbal medicine balls to the set thickness. Plate 2 rises and resets; the four push plates 11 alternately push the herbal medicine ball, causing it to move on the base plate 1 and level its lower surface (this step aims to remove any slight depressions or protrusions in the herbal medicine ball caused by the elastic membrane, pushing them out of the elastic membrane and into contact with the flat parts of the base plate, thus achieving overall leveling); simultaneously, the stepper motor 41 rotates, aligning the second extrusion plate 3 with the processing area 10, while the first extrusion plate 2 aligns with another processing area and performs leveling. Operation: The second lifting unit 43 drives the second extrusion plate 3 downward, and the extrusion head 30 descends to squeeze the corresponding position of the herbal paste into the first semi-circular hole 13. At the same time, the hydraulic unit 16 draws out the liquid in the first semi-circular hole 13. The elastic membrane 14 deforms under the suction force and adheres tightly to the inner wall of the first semi-circular hole 13. The first semi-circular hole 13 and the second semi-circular hole 31 complete the matching extrusion pelleting operation. The second lifting unit 43 drives the second extrusion plate 3 upward to reset. The hydraulic unit 16 slowly injects liquid into the first semi-circular hole 13 and pushes the elastic membrane 14. The elastic membrane 14 gradually... The stepper motor 41 rotates to make the second extrusion plate 3 face another processing area and extrude into pellets. At the same time, the four push plates 11 run to extrude the remaining Chinese medicine pellets in the current processing area, so that the holes on the Chinese medicine pellets disappear and then the first extrusion plate performs a leveling operation. Of course, when the extrusion operation of the second extrusion plate reaches a set number of times or the volume of the Chinese medicine pellets in the processing area is less than a certain amount, new Chinese medicine pellets are added to the processing area to ensure the continuous operation.

[0029] Using the novel pill-making equipment of this application, while one processing area 10 is leveling the herbal medicine mass, another processing area 10 performs batch extrusion into pills. The two processing areas alternate, and the initially placed herbal medicine mass can undergo multiple extrusion operations to ensure pill production efficiency and quality. The four push plates 11 are used not only to limit the position of the herbal medicine mass but also to control the extrusion area (as the herbal medicine mass becomes smaller, the pushing stroke needs to be controlled to be larger; by controlling the extrusion area, it is ensured that the extrusion head participating in the extrusion can contact a sufficient amount of herbal paste), and to clamp the extruded herbal medicine mass (the two oppositely positioned push rods can push synchronously). The process involves extruding the herbal pellets to eliminate any holes created by the previous pressing operation, ensuring the reliability of the next pressing operation. The coolant not only cools the pellets and the base plate 1, but also, in conjunction with the hydraulic unit, provides support to the elastic membrane during the leveling stage to prevent the herbal pellets from sinking into the first semi-circular hole. During the pelleting stage, it pulls the elastic membrane to deform it and make it fit against the inner wall of the first semi-circular hole, ensuring the smooth transition between leveling and pelleting states. After pelleting, it also pushes the pellets out of the first semi-circular hole, and then the inclined base plate causes the pellets to roll off and be discharged. Each pelleting operation is followed by a discharge, ensuring continuous processing.

[0030] Preferably, the mounting bracket includes a support base 44 fixedly connected to the base plate 1. The top of the support base 44 is provided with an annular track 45 and a slider 46 slidably disposed on the track. A stepper motor 41 is provided at the center of the track 45. A rotating frame 40 is provided at the movable end of the stepper motor 41. The rotating frame 40 is connected to the slider 46. The first extrusion plate 2 and the second extrusion plate 3 are symmetrically distributed around the rotation axis of the rotating frame 40. During operation, the stepper motor 41 drives the rotating frame 40 to rotate. The track 45 and the slider 46 cooperate to provide support for the rotating frame 40. The driving accuracy is high, the overall structure is simple, and the stability is good.

[0031] Preferably, both the first lifting unit 42 and the second lifting unit 43 include a longitudinal lead screw disposed at the end of the rotating frame 40 and a lead screw motor for driving the longitudinal lead screw; a fixing post 5 is disposed on the back of both the first extrusion plate 2 and the second extrusion plate 3, and a guide sleeve 47 is disposed on the rotating frame 40 and sleeved on the fixing post 5; the fixing post 5 is fixedly connected to the lead screw nut of the lead screw, and the guide sleeve 47 is provided with a sliding groove corresponding to the lead screw nut; with this structural design, the guide sleeve 47 can ensure the stability of the lifting of the first extrusion plate and the second extrusion plate, and the lead screw drive can ensure the accuracy of the lifting.

[0032] Preferably, the base plate 1 is provided with a guide groove 17 to guide the rolling pills. A conveyor belt 18 is provided at the bottom of the guide groove 17. When the conveyor belt 18 is running, the forward direction of the upper surface is opposite to the rolling direction of the pills. A receiving belt is provided at the edge of the base plate to collect the pills that have passed through the guide groove 17. The guide groove 17 is provided to guide the falling pills, and the conveyor belt 18 is provided to decelerate the rolling pills and drive them to roll, thereby improving their roundness.

[0033] Preferably, the base plate 1 has an inclination angle of 10-15 degrees. More preferably, the inclination direction of the base plate is along the middle gap between two adjacent push rods, so as to prevent the pill from touching the push plate when it rolls down.
