Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices and relates to a powder medicine production device. Background Art

[0002] In the production process, liquid medicine needs to be dried into granular form by a drying device. Currently, electrothermal constant-temperature drying devices are commonly used for drying. However, in the process of drying liquid medicine into granules by the existing electrothermal constant-temperature liquid medicine drying oven, there are often problems such as uneven drying and poor drying effect. Moreover, after drying is completed, it is inconvenient to take out the dried product due to the high temperature inside the oven, and there is a lack of an effective pushing device.

[0003] Patent CN215538459U discloses an electrothermal constant-temperature liquid medicine drying oven, including an electrothermal constant-temperature drying oven, a box door, a partition board, a chute, a driving motor, a horizontal driving rod, a bevel gear one, a bevel gear two, a vertical driving rod, a turntable, a semi-circular through hole, a rectangular through hole, and an electric telescopic rod. A partition board is fixedly installed in the middle inside the electrothermal constant-temperature drying oven. A chute is provided on the right inner wall of the electrothermal constant-temperature drying oven. The chute is slidably connected with a driving motor. The driving motor is connected to a horizontal driving rod. The horizontal driving rod is connected to a bevel gear one. The bevel gear one is meshed and connected to a bevel gear two. The bevel gear two is connected to a vertical driving rod. An electric telescopic rod is horizontally installed on the rear inner wall of the electrothermal constant-temperature drying oven. When the driving motor is started, it drives the horizontal driving rod to rotate, causing the bevel gear one to rotate, driving the meshed bevel gear two to rotate, and causing the vertical driving rod connected to the bevel gear two to rotate. The turntable rotates at a constant speed, driving the liquid medicine container to rotate slowly, making the liquid medicine drying more uniform and having a good drying effect. An electric telescopic rod is provided inside. After drying is completed, it automatically pushes the driving motor to move out of the box along the chute, and can drive the turntable to move out of the box along the rectangular through hole, facilitating the taking out of the drying container.

[0004] However, the above drying method is a centralized baking type, which not only easily damages the function of the medicine at high temperature, but also has low efficiency, no continuous output, and requires centralized processing. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art and propose a powder medicine production device. The technical problem to be solved by the present invention is: how to improve production efficiency.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A powder medicine production device, characterized in that the medicine production device includes a number of groups of outer rollers, intermediate rollers, inner rollers and liquid medicine belts that are arranged in one-to-one correspondence and rotate. A fan is provided on the outer roller, guide wheels are provided at both ends of the intermediate roller, and both ends of the liquid medicine belt are connected to the guide wheels at both ends of each intermediate roller. A transmission mechanism capable of synchronously rotating the two is provided between the outer roller and the intermediate roller, and a heating rod is provided on the inner roller; the medicine production device further includes a liquid medicine pool corresponding to the liquid medicine belt, a medicine powder collection box, and a driving mechanism capable of driving the liquid medicine belt to move. The liquid medicine belt passes through the liquid in the liquid medicine pool.

[0008] Its working principle is as follows: When in use, the driving mechanism drives the liquid medicine belt to move, thereby driving the intermediate roller to rotate, and then driving the outer roller to rotate through the transmission mechanism. During this process, the liquid medicine belt adheres to the liquid medicine in the liquid medicine pool. Since the outer roller rotates synchronously, the fan on the outer roller can blow dry the liquid medicine on the liquid medicine belt, and the heating rod on the inner roller can also dry the liquid medicine on the liquid medicine belt, thereby improving the efficiency of forming medicine powder; finally, after the liquid medicine on the liquid medicine belt forms medicine powder, it can fall into the medicine powder collection box under the action of gravity. Compared with the prior art, the production efficiency of this medicine production device is higher.

[0009] In the above-mentioned powder medicine production device, the medicine production device further includes a bracket. The liquid medicine pool is fixed on the bracket. A number of liquid medicine rollers corresponding to the liquid medicine belt are also provided on the bracket. The driving mechanism includes a motor connected to one of the liquid medicine rollers. An adhesion roller corresponding to the liquid medicine belt is provided in the liquid medicine pool. The liquid medicine roller, the adhesion roller and the guide wheel are all connected through guide edges to achieve synchronous movement, and both ends of the liquid medicine belt are fixed on the guide edges. The motor rotates, driving the liquid medicine roller, the adhesion roller and the guide wheel to rotate, thereby driving the liquid medicine belt to move.

[0010] In the above-mentioned powder medicine production device, the liquid medicine pool is provided with a slide rail in the vertical direction. Both ends of the adhesion roller are rotatably connected with sliders, and the sliders are slidably arranged on the slide rail. A driving source capable of driving the sliders to move is also provided on the liquid medicine pool. The driving source drives the sliders to move, thereby driving the adhesion roller to lift and lower, so as to cooperate with the rise and fall of the liquid level to ensure that the liquid medicine in the liquid medicine pool can be fully utilized.

[0011] In the above-mentioned powder medicine production device, the driving source includes a lead screw and a motor. A threaded hole is opened on the slider. One end of the lead screw is connected to the output end of the motor, and the other end of the lead screw passes through the threaded hole and is rotatably arranged at the bottom of the slide rail. The motor rotates, driving the lead screw to rotate, thereby driving the slider to lift and lower, and then realizing the lifting and lowering of the adhesion roller.

[0012] In the above-mentioned powder medicine production device, the transmission mechanism includes a first pulley, a second pulley and a transmission belt. The first pulley and the second pulley are respectively fixed to the ends of the outer roller and the middle roller, and the transmission belt is respectively connected to the first pulley and the second pulley. The liquid medicine belt drives the middle roller to rotate, thereby driving the first pulley to rotate through the second pulley and the transmission belt, and then driving the outer roller to rotate, and finally realizing the rotation of the fan.

[0013] In the above-mentioned powder medicine production device, the medicine production device includes a plurality of scissor mechanisms. The scissor mechanism includes a plurality of connecting rods hinged end to end in sequence, so that each scissor mechanism encloses a ring. The end of the outer roller is hinged to the outer end of the connecting rod, the end of the middle roller is hinged to the middle of the connecting rod, and the end of the inner roller is hinged to the inner end of the connecting rod; the medicine production device also includes two cylinders, and the two cylinders are respectively connected to the uppermost inner roller and the lowermost inner roller. The cylinders drive the inner roller to move, which can make each scissor mechanism swing around its midpoint, so as to adjust the distance between the outer roller, the middle roller and the inner roller, and thus adjust the air drying and drying speed.

[0014] In the above-mentioned powder medicine production device, the liquid medicine pool is located at the lower left of each scissor mechanism, and the medicine powder collection box is located at the lower right of each scissor mechanism. The fan on the outer roller near the medicine powder collection box can contact the liquid medicine belt on the corresponding middle roller. After the liquid medicine is dried to form medicine powder, it can fall into the medicine powder collection box under the action of gravity. In order to avoid the adhesion of medicine powder, the fan near the medicine powder collection box can contact the liquid medicine belt, so as to scrape the medicine powder on the liquid medicine belt into the medicine powder collection box, improving the production efficiency.

[0015] In the above-mentioned powder medicine production device, an air suction cylinder is arranged on the bracket. The air suction cylinder is located between the liquid medicine pool and the liquid medicine belt. The lower end of the air suction cylinder is connected with an auxiliary collection box, and the upper end of the air suction cylinder is close to the inner surface of the liquid medicine belt. The medicine powder on the outer surface of the liquid medicine belt can fall into the medicine powder collection box under the action of gravity and the fan. After the air suction cylinder is designed, the medicine powder on the inner surface of the liquid medicine belt can be adsorbed into the auxiliary collection box, thus avoiding the waste of medicine powder.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The production efficiency of this medicine production device is higher;

[0018] 2. The driving source drives the slider to move, thereby driving the adhesion roller to lift, so as to cooperate with the liquid level rise and fall, ensuring that the liquid medicine in the liquid medicine pool can be fully utilized. Description of the Drawings
