Description

Technical Field

[0001] The present invention relates to the technical field of liquid medicine mixing, and particularly to a liquid medicine mixing device for the production of polylactic acid anti-adhesion gel with a sterilization function. Background Art

[0002] As a biomaterial with important application value in the medical field, polylactic acid anti-adhesion gel plays a key role in preventing postoperative tissue adhesion. In surgical operations, tissue adhesion may lead to serious complications such as pain and organ dysfunction. The emergence of polylactic acid anti-adhesion gel provides an effective means to solve this problem. It forms a physical barrier at the surgical site to prevent direct contact and adhesion between tissues, and at the same time has good biocompatibility and biodegradability, and can be gradually absorbed in the body without causing long-term adverse effects on the human body.

[0003] In traditional filtration sterilization, during the filtration process, due to the blockage of the filter pores, the pressure of the liquid medicine in the filter will gradually increase, which may cause the filter to rupture or the liquid medicine to leak, thus affecting the continuity and safety of production. An appropriate viscosity can ensure that the gel is evenly applied at the surgical site and forms a stable physical barrier. If the viscosity is too high, the gel may be difficult to inject or apply, affecting the surgical operation; if the viscosity is too low, the gel may not effectively adhere to the surgical site and cannot play the role of preventing adhesion.

[0004] Traditional stirring methods often have the problem of uneven stirring. Ordinary stirring paddles cannot generate sufficient shear force and turbulence in complex liquid medicine systems, resulting in insufficient mixing of the liquid medicine in some areas. Summary of the Invention

[0005] The purpose of the present invention is to provide a liquid medicine mixing device for the production of polylactic acid anti-adhesion gel with a sterilization function to solve the problems raised in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: The liquid medicine mixing device for the production of polylactic acid anti-adhesion gel with a sterilization function includes a mixing barrel, a mixing unit, a sterilization unit and a controller. The mixing barrel is placed on a horizontal base. An inlet and an outlet are provided on the mixing barrel. The mixing unit is fixedly connected to the mixing barrel. The sterilization unit is fixedly installed in the mixing barrel. The mixing unit has the function of changing the viscosity of the mixed liquid medicine. The sterilization unit has the functions of self-cleaning and sterilizing the mixed liquid medicine. The mixing unit and the sterilization unit are electrically connected. The controller is fixedly installed on the surface of one end of the mixing barrel away from the horizontal base. The controller is electrically connected to the mixing unit. The controller is electrically connected to the sterilization unit.

[0007] The mixing barrel is used to install and fix the mixing unit, the sterilization unit and the controller. The mixing unit is used for uniformly stirring the liquid medicine, the sterilization unit is used for sterilizing the mixed liquid medicine, and the controller is used to control the start and stop of the mixing unit and the sterilization unit. When the mixed liquid medicine is transported from the mixing barrel to the mixing unit for sufficient and uniform stirring to improve the mixing efficiency, and the mixed liquid medicine after mixing enters the sterilization unit for sterilization while self-cleaning to improve the sterilization efficiency. Finally, the liquid medicine after mixing and sterilization is discharged from the liquid outlet of the mixing barrel, thereby improving the production efficiency of the polylactic acid anti-adhesion gel.

[0008] Further, the mixing unit includes a motor, a mounting frame, a rotating rod, a swing arm, an electromagnet 1, a rack, a gear, a sliding table, a rotating shaft, a sliding cylinder, a torsion spring, a fan blade, a straight cylinder, a long rod and an electromagnet 2. The mounting frame is fixedly installed on the outer surface of the mixing barrel through a bent rod. The fixed end of the motor is fixedly installed on the mounting frame. The output end of the motor penetrates the mixing barrel and is fixedly connected to the rotating rod. The rotating rod is rotatably installed inside the mixing barrel parallel to the vertical axis. One end of the swing arm is rotatably connected to the rotating rod, and the other end is rotatably connected to the sliding table. The swing arm is composed of two straight rods and a frustum. Both straight rods are rotatably installed on the frustum. The electromagnet 1 is fixedly installed on the frustum of the swing arm. The electromagnet 1 is fixedly connected to the rack. The rack is meshed with the gear. The gear is fixedly installed at the end of the rotating shaft away from the horizontal base. A turntable is arranged on the inner surface of the mixing barrel. The rotating shaft is rotatably installed on the turntable on the inner surface of the mixing barrel near the horizontal base. External threads are arranged on the surface of the rotating shaft. The sliding cylinder is sleeved on the outer surface of the rotating shaft. Internal threads corresponding to the external threads of the rotating shaft are arranged inside the sliding cylinder. The fan blade is connected to the sliding cylinder through a torsion spring. One end of the long rod is fixedly installed on the end of the fan blade away from the sliding cylinder, and the other end is fixedly connected to the electromagnet 2. The electromagnet 2 is slidably installed inside the straight cylinder. The straight cylinder is sleeved on the outer surface of the long rod.

[0009] Further, the mixing unit further includes a support rod, a coil, a telescopic spring, a stirring plate, a first electrode plate, a second electrode plate, a buffer spring, a one-way coarse filter plate, a displacement sensor, a pressure-receiving concave platform, a heating plate, and a hydraulic rod. One end of the support rod parallel to the horizontal axis is fixedly installed on the rotating rod, and the other end is slidably connected to the sliding table. The coil is evenly wound around the outer surface of the support rod. One end of the telescopic spring is fixedly connected to the rotating rod, and the other end is fixedly connected to the stirring plate. The hydraulic rod is electrically connected to the sliding table. The pressure-receiving concave platform is fixedly installed on the end face of the stirring plate that receives pressure. There is a cavity inside the pressure-receiving concave platform. The pressure-receiving concave platform is connected to the heating plate through a buffer spring. The first electrode plate is fixedly installed on the end face of the heating plate close to the pressure-receiving concave platform. The second electrode plate is fixedly installed on the end face of the pressure-receiving concave platform close to the heating plate. The displacement sensor is fixedly installed on the end face of the pressure-receiving concave platform close to the heating plate. The second electrode plate is electrically connected to the sterilization unit. The one-way coarse filter plate is vertically and fixedly installed on the inner surface of the mixing barrel. The fixed end of the hydraulic rod is fixedly installed on the rotating rod, and the telescopic end of the hydraulic rod is fixedly connected to the stirring plate.

[0010] When the mixed liquid medicine is poured into the mixing barrel through the liquid inlet of the mixing barrel, the controller controls the motor to start, so that the rotating rod rotates to drive the swing arm to rotate synchronously. When the controller passes opposite currents into the two electromagnets I to make the two electromagnets I present opposite polarities, under the action of the attraction force, the two electromagnets I approach each other. On the one hand, during the process of driving the racks to move relative to each other, the gear rotates clockwise, so that the rotating shaft rotates. Under the action of the sliding cylinder, the upper and lower groups of fan blades rotate and approach each other at the same time. At the same time, the controller passes opposite currents into the two electromagnets II, so that the two electromagnets II attract each other, thereby stretching the long rod, driving the fan blades to approach each other and pulling the upper fan blade to squeeze the torsion spring at the same time. The fan blade flips downward to push the upper-layer mixed solution to the middle layer, and the lower fan blade squeezes the torsion spring and flips upward to push the lower-layer mixed solution to the middle layer. On the other hand, under the action of the swing arm, the sliding table is pushed to move outward. When the controller passes the same current into the two electromagnets I, so that the two electromagnets I have the same polarity and repel each other. During the process of the two electromagnets I moving away from each other, the rack is driven to move. On the one hand, under the action of the swing arm, the sliding table is pulled to move inward. On the other hand, the gear rotates counterclockwise. The rotation of the gear drives the rotating shaft, driving the upper and lower two sliding cylinders to rotate synchronously. The upper sliding cylinder moves upward along the thread on the rotating shaft, and the lower sliding cylinder moves downward along the thread on the rotating shaft, thereby pulling the long rod to drive the two electromagnets II to move away from each other, thereby pushing the upper fan blade to squeeze the torsion spring and flip upward, pushing the mixed liquid medicine in the middle layer upward, and the lower fan blade squeezes the torsion spring and flips downward, pushing the mixed liquid medicine in the middle layer downward. Thus, while the fan blades rotate around the center during the revolution process, during the process of the two electromagnets I approaching and moving away from each other, the fan blades flip up and down, stirring the mixed solutions at different layers inside the mixing barrel, breaking the layering phenomenon of the mixed solutions, and thus improving the mixing efficiency.

[0011] When the swing arm drives the sliding table to move synchronously to the right, the effective number of turns of the coil gradually decreases at this time, so that the current flowing into the hydraulic rod gradually increases, causing the hydraulic rod to extend and push the stirring plate to extend outward. When the swing arm drives the sliding table to move synchronously to the left, the effective number of turns of the coil gradually increases, and the current flowing into the hydraulic rod gradually decreases. At this time, under the action of the restoring force of the telescopic spring, the stirring plate is driven to reset, so that the stirring plate makes a telescopic motion, increasing the stirring range and improving the uniformity of the mixed liquid medicine.

[0012] When the stirring plate encounters a high-viscosity area during the process of stirring and mixing the liquid medicine, at this time, under the action of pressure, it pushes the heating plate, driving the first electrode plate to squeeze the buffer spring, so that the second electrode plate contacts the first electrode plate, delivering current to the telescopic shaft. At the same time, the displacement sensor detects that the length of the buffer spring has changed and feeds back an electrical signal to the controller, so that the controller delivers current to the heating plate at this place while reducing the motor speed, increasing the contact time between the heating plate and the mixed solution in the high-viscosity area, thereby reducing the viscosity of the mixed liquid medicine in the high-viscosity area and improving the uniformity of the mixed liquid medicine.

[0013] Further, the sterilization unit includes a one-way sterilization filter plate, a right-angle bent plate, a push block, a blocking plate, an arc-shaped sponge block, an electric telescopic rod and a telescopic shaft. The telescopic shaft is electrically connected to the second electrode plate. The one-way sterilization filter plate is vertically and fixedly installed on the inner surface of the mixing barrel. The right-angle bent plate is composed of an arc-shaped horizontal part and a rectangular vertical part. The push block is slidably installed inside the rectangular vertical part of the right-angle bent plate. One end of the push block is fixedly connected to the blocking plate. The blocking plate is slidably installed inside the rectangular vertical part of the right-angle bent plate. The arc-shaped sponge block is fixedly installed at the end of the arc-shaped horizontal part of the right-angle bent plate. The fixed end of the electric telescopic rod is fixedly connected to the inner surface of the mixing barrel. The telescopic end of the electric telescopic rod is fixedly connected to the right-angle bent plate. The fixed end of the telescopic shaft is fixedly connected inside the arc-shaped part of the right-angle bent plate. The telescopic end of the telescopic shaft is fixedly connected to the push block.

[0014] When the first electrode plate comes into contact with the second electrode plate, it indicates that the viscosity of the mixed liquid medicine at that place has not reached the set viscosity value. At this time, the current supplied by the controller to the first electrode plate is continuously supplied to the telescopic shaft through the second electrode plate, thereby changing the circuit of the current in the telescopic shaft and changing the direction of the current flowing into the telescopic shaft, causing the telescopic shaft to extend and push the push block to drive the sealing plate to seal the one-way coarse filter plate, preventing the unmixed mixed liquid medicine from mixing with the already mixed liquid medicine, resulting in deviation in the uniformity of the liquid medicine and a decline in production quality. When the first electrode plate and the second electrode plate are not in contact, it indicates that the viscosity of the mixed liquid medicine at that place has reached the set viscosity value. At this time, the controller controls the electric telescopic rod to start the contraction process. While driving the right-angle bent plate to move downward, the direction of the current flowing into the telescopic shaft is restored, thereby pulling the push block and the sealing plate to move upward, opening the one-way coarse filter plate, and enabling the mixed liquid medicine after mixing to enter the chamber between the one-way coarse filter plate and the one-way sterilization filter plate. During the downward movement of the right-angle bent plate, on the one hand, the mixed liquid medicine after mixing is extruded from the one-way sterilization filter plate for sterilization, accelerating the sterilization efficiency. On the other hand, during the downward movement of the arc-shaped sponge block, the one-way sterilization filter plate is cleaned to prevent the filter holes from being blocked and affecting the sterilization effect and efficiency of the next mixed liquid medicine.

[0015] Further, the two electromagnets II have the same polarity initially.

[0016] In order to maximize the initial distance between the upper and lower groups of fan blades and change the angles of the fan blades at all times during the process of approaching each other as the rotating shaft rotates, so as to generate stirring forces in different directions at different heights and positions, effectively break the layering phenomenon of the material, fully mix each layer of the material, and form a complex flow field in the mixing barrel at the same time, enhancing the fluidity of the material, thereby improving the mixing effect of the mixed liquid medicine.

[0017] Further, the end of the coil close to the rotating rod is the current input end.

[0018] In order to facilitate changing the effective number of turns of the coil during the movement of the sliding table on the support rod, thereby controlling the stirring range of the stirring plate, being able to more effectively break the concentration gradient in the liquid medicine, improving the mixing uniformity of the mixed liquid medicine and shortening the time required for the entire mixing process, and improving the stirring efficiency.

[0019] Further, the coil is electrically connected to the controller, the electromagnet I is electrically connected to the controller, the electromagnet II is electrically connected to the controller, and the first electrode plate is electrically connected to the controller.

[0020] In order to facilitate the device to react automatically and in a timely manner, facilitate heating the heating plate when the stirring plate passes through the area with too high viscosity, reduce the viscosity of the mixed liquid medicine, thereby improving the mixing uniformity of the mixed liquid medicine while controlling the viscosity to be consistent and improving the production quality.

[0021] Further, a vertical plate is arranged inside the mixing barrel. The vertical plate, the one-way coarse filter plate and the one-way sterilization filter plate divide the mixing barrel into three equal chambers, and the vertical plate is a closed plate.

[0022] As a closed plate, the vertical plate can effectively prevent the mixed liquid in different chambers from flowing back and interfering with each other before completing the mixing of their respective stages, avoiding the re-mixing of the already mixed part by the insufficiently mixed part, and ensuring the orderliness and stability of the mixing.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, when two electromagnets in the mixing unit are energized with currents in different directions, the sliding table is pushed to move during the process of approaching and separating from each other, changing the effective number of turns of the coil, so that the current flowing into the hydraulic rod changes at all times. Thus, in cooperation with the telescopic spring, the stirring plate always changes the stirring range, improving the uniformity of the mixed liquid medicine. At the same time, when the second electromagnet is energized with currents in different directions, the two second electromagnets attract and repel each other, driving the angle of the fan blade to deflect, causing the fan blade to swing during the movement, destroying the mixed liquid medicine at different levels, and improving the uniformity of the mixed liquid medicine, thereby improving the mixing efficiency.

[0024] 2. During the process of the stirring plate in the mixing unit stirring and mixing the liquid medicine, when it encounters a high-viscosity area, under the action of pressure, it pushes the heating plate, driving the first electrode plate to squeeze the buffer spring, so that the second electrode plate contacts the first electrode plate, delivering current to the telescopic shaft. At the same time, the displacement sensor detects that the length of the buffer spring has changed and feeds an electrical signal back to the controller. Thus, while the controller delivers current to the heating plate at this place, it reduces the motor speed, increasing the contact time between the heating plate and the mixed solution in the high-viscosity area, thereby reducing the viscosity of the mixed liquid medicine in the high-viscosity area and improving the uniformity of the mixed liquid medicine.

[0025] 3. In the present invention, when the first electrode plate and the second electrode plate contact each other, the direction of the current in the telescopic shaft in the sterilization unit is changed, so that the telescopic shaft extends to push the push block to drive the plugging plate to block the one-way coarse filter plate, avoiding the mixing of the unmixed mixed liquid medicine with the already mixed liquid medicine, which may lead to deviation in the uniformity of the liquid medicine and a decline in production quality. When the first electrode plate and the second electrode plate do not contact, while the electric telescopic rod drives the right-angle bent plate to move downward, the direction of the current flowing into the telescopic shaft is restored, thereby pulling the push block and the plugging plate to move upward, opening the one-way coarse filter plate, and cooperating with the right-angle bent plate to squeeze the mixed liquid medicine out of the one-way sterilization filter plate for sterilization, increasing the sterilization efficiency. On the other hand, the arc-shaped sponge block cleans the one-way sterilization filter plate to avoid blockage of the filter holes, affecting the sterilization effect and efficiency of the next mixed liquid medicine.

[0031] As Figure 2 , 5 , 6, 7, 8, 9 show, the mixing unit 2 includes a motor 21, a mounting bracket 22, a rotating rod 23, a swing arm 24, an electromagnet 25, a rack 26, a gear 27, a sliding table 28, a rotating shaft 29, a sliding cylinder 210, a torsion spring 211, a fan blade 212, a straight cylinder 213, a long rod 214 and an electromagnet 215.

The electromagnet 215 is slidably installed inside the straight cylinder 213. The straight cylinder 213 is sleeved on the outer surface of the long rod 214.

[0032] As Figure 5 , 6As shown in Figures 8, 10, 11, and 12, the mixing unit 2 further includes a support rod 216, a coil 217, a telescopic spring 218, a stirring plate 219, a first electrode plate 220, a second electrode plate 221, a buffer spring 222, a one-way coarse filter plate 223, a displacement sensor 224, a pressure-receiving concave platform 225, a heating plate 226, and a hydraulic rod 227. One end of the support rod 216 parallel to the horizontal axis is fixedly installed on the rotating rod 23, and the other end is slidably connected to the sliding table 28. The coil 217 is evenly wound around the outer surface of the support rod 216. One end of the telescopic spring 218 is fixedly connected to the rotating rod 23, and the other end is fixedly connected to the stirring plate 219. The hydraulic rod 227 is electrically connected to the sliding table 28. The pressure-receiving concave platform 225 is fixedly installed on the pressure-receiving end surface of the stirring plate 219. There is a cavity inside the pressure-receiving concave platform 225. The pressure-receiving concave platform 225 is connected to the heating plate 226 through the buffer spring 222. The first electrode plate 220 is fixedly installed on the end surface of the heating plate 226 close to the pressure-receiving concave platform 225. The second electrode plate 221 is fixedly installed on the end surface of the pressure-receiving concave platform 225 close to the heating plate 226. The displacement sensor 224 is fixedly installed on the end surface of the pressure-receiving concave platform 225 close to the heating plate 226. The second electrode plate 221 is electrically connected to the sterilization unit 3. The one-way coarse filter plate 223 is vertically and fixedly installed on the inner surface of the mixing barrel 1. The fixed end of the hydraulic rod 227 is fixedly installed on the rotating rod 23, and the telescopic end of the hydraulic rod 227 is fixedly connected to the stirring plate 219.

[0033] When the mixed liquid medicine is poured into the interior of the mixing barrel 1 through the liquid inlet of the mixing barrel 1, the controller 4 controls the motor 21 to start, so that the rotating rod 23 rotates to drive the swing arm 24 to rotate synchronously. When the controller 4 passes opposite currents into the first electromagnets 25 to make the two first electromagnets 25 present opposite polarities, under the action of the attraction force, the two first electromagnets 25 approach each other. On the one hand, during the process of driving the racks 26 to move relative to each other, the gear 27 rotates clockwise, so that the rotating shaft 29 rotates. Under the action of the sliding cylinder 210, the upper and lower groups of fan blades 212 rotate and approach each other at the same time. At the same time, the controller 4 passes opposite currents into the second electromagnets 215, so that the two second electromagnets 215 attract each other, thereby stretching the long rod 214, driving the fan blades 212 to approach each other and pulling the upper fan blades 212 to squeeze the torsion springs 211 at the same time. The fan blades 212 turn downward to push the upper-layer mixed solution to the middle layer, and the lower fan blades 212 squeeze the torsion springs 211 and turn upward to push the lower-layer mixed solution to the middle layer. On the other hand, under the action of the swing arm 24, the sliding table 28 is pushed to move outwards. When the controller 4 passes the same current into the first electromagnets 25, so that the two first electromagnets 25 have the same polarity and repel each other. During the process of the first electromagnets 25 moving away from each other, the racks 26 are driven to move. On the one hand, under the action of the swing arm 24, the sliding table 28 is pulled to move inwards. On the other hand, the gear 27 rotates counterclockwise. The rotation of the gear 27 drives the rotating shaft 29, driving the upper and lower two sliding cylinders 210 to rotate synchronously. The upper sliding cylinder 210 moves upward along the thread on the rotating shaft 29, and the lower sliding cylinder 210 moves downward along the thread on the rotating shaft 29, thereby pulling the long rod 214 to drive the second electromagnets 215 to move away from each other, thereby pushing the upper fan blades 212 to squeeze the torsion springs 211 and turn upward to push the mixed liquid medicine in the middle layer upward, and the lower fan blades 212 squeeze the torsion springs 211 and turn downward to push the mixed liquid medicine in the middle layer downward. Thus, while the fan blades 212 rotate around a circle and rotate around their own axes, during the process of the first electromagnets 25 approaching and moving away from each other, the fan blades 212 turn up and down, stirring the mixed solutions at different layers inside the mixing barrel 1, breaking the layering phenomenon of the mixed solution, and thus improving the mixing efficiency.

[0034] When the swing arm 24 drives the sliding table 28 to move synchronously to the right, at this time the effective number of turns of the coil 217 gradually decreases, so that the current passing into the hydraulic rod 227 gradually increases, causing the hydraulic rod 227 to extend and thus pushing the stirring plate 219 to extend outwards. When the swing arm 24 drives the sliding table 28 to move synchronously to the left, the effective number of turns of the coil 217 gradually increases, and the current passing into the hydraulic rod 227 gradually decreases. At this time, under the action of the restoring force of the telescopic spring 218, the stirring plate 219 is driven to reset, so that the stirring plate 219 makes a telescopic movement, increasing the stirring range and improving the uniformity of the mixed liquid medicine.

[0035] When the stirring plate 219 encounters a high-viscosity area during the process of stirring and mixing the liquid medicine, under the action of pressure at this time, it pushes the heating plate 226, drives the first electrode plate 220 to squeeze the buffer spring 222, so that the second electrode plate 221 contacts the first electrode plate 220, conveys the current to the telescopic shaft 37. At the same time, the displacement sensor 224 detects that the length of the buffer spring 222 has changed, and feeds an electrical signal back to the controller 4, so that the controller 4 conveys current to the heating plate 226 at this place while reducing the speed of the motor 21, increasing the contact time between the heating plate 226 and the mixed solution in the high-viscosity area, thereby reducing the viscosity of the mixed liquid medicine in the high-viscosity area and improving the uniformity of the mixed liquid medicine.

[0036] As Figure 4 , 5 , shown in Figure 13, the sterilization unit 3 includes a one-way sterilization filter plate 31, a right-angle bent plate 32, a push block 33, a plugging plate 34, an arc-shaped sponge block 35, an electric telescopic rod 36 and a telescopic shaft 37. The telescopic shaft 37 is electrically connected to the second electrode plate 221. The one-way sterilization filter plate 31 is vertically and fixedly installed on the inner surface of the mixing barrel 1. The right-angle bent plate 32 is composed of an arc-shaped horizontal part and a rectangular vertical part. The push block 33 is slidably installed inside the rectangular vertical part of the right-angle bent plate 32. One end of the push block 33 is fixedly connected to the plugging plate 34. The plugging plate 34 is slidably installed inside the rectangular vertical part of the right-angle bent plate 32. The arc-shaped sponge block 35 is fixedly installed at the end of the arc-shaped horizontal part of the right-angle bent plate 32. The fixed end of the electric telescopic rod 36 is fixedly connected to the inner surface of the mixing barrel 1. The telescopic end of the electric telescopic rod 36 is fixedly connected to the right-angle bent plate 32. The fixed end of the telescopic shaft 37 is fixedly connected inside the arc-shaped part of the right-angle bent plate 32. The telescopic end of the telescopic shaft 37 is fixedly connected to the push block 33.

[0037] When the first electrode plate 220 comes into contact with the second electrode plate 221, it indicates that the viscosity of the mixed liquid medicine at this place has not reached the set viscosity value. At this time, the current supplied by the controller 4 to the first electrode plate 220 is continuously supplied to the telescopic shaft 37 through the second electrode plate 221, thereby changing the circuit of the current in the telescopic shaft 37 and changing the direction of the current flowing into the telescopic shaft 37, causing the telescopic shaft 37 to extend and push the push block 33 to drive the sealing plate 34 to block the one-way coarse filter plate 223, preventing the unmixed mixed liquid medicine from mixing with the already mixed liquid medicine, resulting in deviation in the uniformity of the liquid medicine and causing a decline in production quality. When the first electrode plate 220 is not in contact with the second electrode plate 221, it indicates that the viscosity of the mixed liquid medicine at this place has reached the set viscosity value. At this time, the controller 4 controls the electric telescopic rod 36 to start the contraction process. While driving the right-angle bent plate 32 to move downward, the direction of the current flowing into the telescopic shaft 37 is restored, thereby pulling the push block 33 and the sealing plate 34 to move upward to open the one-way coarse filter plate 223, allowing the mixed and completed mixed liquid medicine to enter the chamber between the one-way coarse filter plate 223 and the one-way sterilizing filter plate 31. During the downward movement of the right-angle bent plate 32, on the one hand, the mixed and completed liquid medicine is extruded from the one-way sterilizing filter plate 31 for sterilization, accelerating the sterilization efficiency. On the other hand, during the downward movement of the arc-shaped sponge block 35, the one-way sterilizing filter plate 31 is cleaned to prevent the filter holes from being blocked and affecting the sterilization effect and efficiency of the next mixed liquid medicine.

[0038] As Figure 9 shown, the polarities of the two electromagnets two 215 are the same initially.

[0039] In order to maximize the initial distance between the upper and lower groups of fan blades 212 and change the angles of the fan blades 212 at all times during the process of approaching each other as the rotating shaft 29 rotates, so as to generate stirring forces in different directions at different heights and positions, effectively break the layering phenomenon of the material, fully mix each layer of the material, and at the same time form a complex flow field in the mixing barrel 1, enhancing the fluidity of the material, thereby improving the mixing effect of the mixed liquid medicine.

[0040] As Figure 8 shown, the end of the coil 217 close to the rotating rod 23 is the current input end.

[0041] In order to facilitate changing the effective number of turns of the coil 217 during the movement of the sliding table 28 on the support rod 216, thereby controlling the stirring range of the stirring plate 219, being able to more effectively break the concentration gradient in the liquid medicine, improving the uniformity of the mixed liquid medicine and shortening the time required for the entire mixing process, and improving the stirring efficiency.

[0042] As Figure 8 、 9, as shown in Figures 10 and 12, the coil 217 is electrically connected to the controller 4, the first electromagnet 25 is electrically connected to the controller 4, the second electromagnet 215 is electrically connected to the controller 4, and the first electrode plate 220 is electrically connected to the controller 4.

[0043] To facilitate the automatic and timely reaction of the device, when the stirring plate 219 passes through the area with too high viscosity, the heating plate 226 is heated to reduce the viscosity of the mixed liquid medicine, thereby improving the mixing uniformity of the mixed liquid medicine while controlling the viscosity to be consistent and improving the production quality.

[0044] As Figure 5 shown, a vertical plate 11 is provided inside the mixing barrel 1. The vertical plate 11, the one-way coarse filter plate 223, and the one-way sterilization filter plate 31 divide the mixing barrel 1 into three equal chambers, and the vertical plate 11 is a closed plate.

[0045] As a closed plate, the vertical plate 11 can effectively prevent the mixed liquids in different chambers from flowing back and interfering with each other before completing the mixing in their respective stages, avoiding the re - mixing of the already mixed part by the part that has not been fully mixed, and ensuring the orderliness and stability of the mixing.

[0046] The working principle of the present invention: When the mixed liquid medicine is poured into the interior of the mixing barrel 1 through the liquid inlet of the mixing barrel 1, the controller 4 controls the motor 21 to start, so that the rotating rod 23 rotates to drive the swing arm 24 to rotate synchronously. When the controller 4 passes opposite currents into the electromagnets 25, the two electromagnets 25 present opposite polarities. Under the action of the attraction force, the two electromagnets 25 approach each other. On the one hand, when the racks 26 move relative to each other, the gear 27 rotates clockwise, so that the rotating shaft 29 rotates. Under the action of the sliding cylinder 210, the upper and lower groups of fan blades 212 rotate and approach each other at the same time. At the same time, the controller 4 passes opposite currents into the electromagnets 215, so that the two electromagnets 215 attract each other, thereby stretching the long rod 214, driving the fan blades 212 to approach each other and pulling the upper fan blades 212 to squeeze the torsion spring 211. The fan blades 212 turn downward to push the upper-layer mixed solution to the middle layer, and the lower fan blades 212 squeeze the torsion spring 211 and turn upward to push the lower-layer mixed solution to the middle layer. On the other hand, under the action of the swing arm 24, the slide table 28 is pushed to move outward. When the controller 4 passes the same current into the electromagnets 25, the two electromagnets 25 have the same polarity and repel each other. During the process of the electromagnets 25 moving away from each other, the racks 26 are driven to move. On the one hand, under the action of the swing arm 24, the slide table 28 is pulled to move inward. On the other hand, the gear 27 rotates counterclockwise. The rotation of the gear 27 drives the rotating shaft 29, driving the upper and lower sliding cylinders 210 to rotate synchronously. The upper sliding cylinder 210 moves upward along the thread on the rotating shaft 29, and the lower sliding cylinder 210 moves downward along the thread on the rotating shaft 29, thereby pulling the long rod 214 to drive the electromagnets 215 to move away from each other, thereby pushing the upper fan blades 212 to squeeze the torsion spring 211 and turn upward to push the middle-layer mixed liquid medicine upward, and the lower fan blades 212 squeeze the torsion spring 211 and turn downward to push the middle-layer mixed liquid medicine downward. Thus, while the fan blades 212 rotate around the sun and rotate on their own axes, during the process of the electromagnets 25 approaching and moving away from each other, the fan blades 212 turn up and down, stirring the mixed solutions at different layers inside the mixing barrel 1, destroying the layering phenomenon of the mixed solutions, and thus improving the mixing efficiency.

[0047] When the swing arm 24 drives the slide table 28 to move synchronously to the right, at this time, the effective number of turns of the coil 217 gradually decreases, so that the current passing into the hydraulic rod 227 gradually increases, causing the hydraulic rod 227 to extend and push the stirring plate 219 to extend outward. When the swing arm 24 drives the slide table 28 to move synchronously to the left, the effective number of turns of the coil 217 gradually increases, and the current passing into the hydraulic rod 227 gradually decreases. At this time, under the action of the restoring force of the telescopic spring 218, the stirring plate 219 is driven to reset, so that the stirring plate 219 makes a telescopic movement, increasing the stirring range and improving the uniformity of the mixed liquid medicine.

[0048] When the stirring plate 219 encounters a high-viscosity area during the process of stirring and mixing the liquid medicine, under the action of pressure at this time, it pushes the heating plate 226, drives the first electrode plate 220 to squeeze the buffer spring 222, so that the second electrode plate 221 contacts the first electrode plate 220, conveys the current to the telescopic shaft 37. At the same time, the displacement sensor 224 detects that the length of the buffer spring 222 has changed, and feeds an electrical signal back to the controller 4, so that the controller 4 conveys current to the heating plate 226 at this place while reducing the speed of the motor 21, increasing the contact time between the heating plate 226 and the mixed solution in the high-viscosity area, thereby reducing the viscosity of the mixed liquid medicine in the high-viscosity area and improving the uniformity of the mixed liquid medicine.

[0049] When the first electrode plate 220 contacts the second electrode plate 221, it indicates that the viscosity of the mixed liquid medicine at this place has not reached the set viscosity value. At this time, the current sent by the controller 4 to the first electrode plate 220 is continuously conveyed to the telescopic shaft 37 through the second electrode plate 221, thereby changing the circuit of the current in the telescopic shaft 37 and changing the direction of the current flowing into the telescopic shaft 37, so that the telescopic shaft 37 extends to push the push block 33 to drive the blocking plate 34 to block the one-way coarse filter plate 223, avoiding the mixing of the unmixed mixed liquid medicine with the already mixed liquid medicine, resulting in deviation of the uniformity of the liquid medicine and deterioration of the production quality. When the first electrode plate 220 does not contact the second electrode plate 221, it indicates that the viscosity of the mixed liquid medicine at this place has reached the set viscosity value. At this time, the controller 4 controls the electric telescopic rod 36 to start the contraction process. While driving the right-angle bent plate 32 to move downward, the direction of the current flowing into the telescopic shaft 37 is restored, thereby pulling the push block 33 and the blocking plate 34 to move upward to open the one-way coarse filter plate 223, so that the mixed and completed mixed liquid medicine enters the chamber between the one-way coarse filter plate 223 and the one-way sterilizing filter plate 31. During the downward movement of the right-angle bent plate 32, on the one hand, the mixed and completed liquid medicine is extruded from the one-way sterilizing filter plate 31 for sterilization to accelerate the sterilization efficiency. On the other hand, during the downward movement of the arc-shaped sponge block 35, the one-way sterilizing filter plate 31 is cleaned to avoid blockage of the filter holes and affect the sterilization effect and efficiency of the next mixed liquid medicine.
