Description

Technical Field

[0001] The present invention belongs to the technical field of pharmaceutical processing, and particularly relates to a medicine moistening device. Background Art

[0002] Drug processing is one of the key equipment for the processing of traditional Chinese medicine decoction pieces. It is mainly used for wetting traditional Chinese medicinal materials to facilitate subsequent processing of the medicinal materials. The active ingredients of some medicinal materials are easily soluble in water. When moistening the medicine, water vapor needs to be introduced under vacuum conditions. By utilizing the penetrability of gas under vacuum conditions, the medicinal materials can be quickly and uniformly softened under low water content.

[0003] In the patent application document with the publication number of CN117323224A, a medicinal material vacuum moistening device is disclosed. It has a tank body, and a medicine moistening drum is arranged inside the tank body. The medicine moistening drum includes a drum. A plurality of through holes are penetrated through the drum. A drum door is connected to the drum. The drum is rotatably connected to one side of the drum door through a hinge. The drum and the other side of the drum door are clamped through a clamping member. Both sides of the drum are fixedly connected with rotating shafts, and the rotating shafts are installed through the side plates.

[0004] The above-mentioned medicine moistening device puts the sliced medicinal materials into the medicine moistening drum in a vacuum state, then introduces circulating steam, and at the same time drives the medicine moistening drum to rotate, thereby completing the medicine moistening. Although this method can prevent the adhesion between the sliced medicinal materials by driving the sliced medicinal materials to roll in the drum, a large number of sliced medicinal materials are stacked in the drum, which still causes some medicinal materials to not fully contact with the water vapor, resulting in uneven moistening of the medicinal materials. As a result, the medicine moistening device cannot ensure the uniformity during medicine moistening, causing some medicinal materials to be over-moistened, the active ingredients of the medicinal materials to be damaged, resulting in a reduction in the medicinal effect. At the same time, some medicinal materials are under-moistened, making it difficult for the active ingredients in the medicinal materials to be fully released, thereby affecting its therapeutic effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a medicine moistening device, aiming to solve the problem that the existing medicine moistening device cannot ensure the uniformity during medicine moistening, resulting in the quality and safety of the medicinal materials not being guaranteed.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A medicine moistening device includes a box body and a medicine moistening mechanism located inside the box body. The medicine moistening mechanism includes a medicine moistening box, a support assembly, a pressing assembly, and a rotating assembly. The medicine moistening box is horizontally arranged inside the box body.

[0007] The support assembly includes a square frame horizontally arranged inside the medicine moistening box. A support frame with a length extending in the front-rear direction is arranged inside the square frame. A support mesh plate is fixedly installed at the top of the support frame for placing sliced medicinal materials.

[0008] The pressing assembly includes two slide plates extending in the left-right direction, the two slide plates are respectively located at the front and rear sides above the supporting assembly, a pressing frame is arranged between the two slide plates, and a pressing mesh plate for pressing the medicinal material slices is fixed at the bottom of the pressing frame.

[0009] The rotating assembly is used to drive the supporting frame and the pressing frame to rotate coaxially synchronously after the pressing assembly presses the medicinal material slices onto the supporting assembly.

[0010] The beneficial effects of the present invention are as follows: by arranging a supporting component and a pressing component, the medicinal material slices are evenly laid on the supporting mesh plate of the supporting component and the medicinal material slices are prevented from stacking on each other during laying, and the supporting component with the laid medicinal material slices is pushed into the medicine moistening box and is located below the pressing component, and then the pressing component is controlled to descend, so that the pressing mesh plate of the pressing component can press the medicinal material slices on the supporting mesh plate, thereby preventing the medicinal material slices from stacking on each other during medicine moistening, resulting in some medicinal materials being unable to fully contact with water vapor, resulting in uneven medicine moistening, and at the same time, during medicine moistening, the supporting mesh plate and the pressing mesh plate are driven to rotate coaxially by the rotating component, and the medicinal material slices can be turned over during medicine moistening, so that the two cross-sections of the medicinal material slices can face the steam in turn, further ensuring the uniformity of medicine moistening.

[0011] The rotating assembly includes two rotating shafts fixedly installed on the front and rear sides of the clamping frame and coaxial with each other, and two split shafts fixedly installed on the front and rear sides of the supporting frame and coaxial with each other. The rotating shaft is rotatably connected to the slide plate, and the split shaft is rotatably connected to the square frame. The split shaft is a half-shaft split along the axial direction, and a socket with an axis perpendicular to the axis of the split shaft is provided on the split surface. A split groove is provided at one end of the rotating shaft close to the supporting frame, and the split groove is cut along the axial direction of the rotating shaft. A plug shaft coaxial with the socket is fixedly installed on the cut surface of the split groove.

[0012] The effect is that by setting a rotating shaft and a split shaft, the rotating shaft that drives the support frame and the clamping frame to rotate coaxially can be divided into two parts. The support frame is rotatably connected to the square frame through the split shaft, and the clamping frame is rotatably connected to the slide plate through the rotating shaft. When the medicine is lubricated, the clamping assembly descends, and the rotating shaft is combined into a complete shaft through the split groove and the plug-in shaft and can rotate on its own, thereby ensuring that the support frame and the clamping frame can rotate coaxially synchronously.

[0013] There are multiple support frames and multiple clamping frames, which correspond to each other one by one and are evenly distributed along the left and right directions of the medicine box. The ends of the rotating shafts on the rear sides of the multiple clamping frames away from the clamping frames penetrate the slide and are connected to the transmission assembly. The transmission assembly includes multiple transmission gears respectively fixed on the outer walls of the multiple rotating shafts, and the multiple transmission gears are connected to each other with a transmission belt.

[0014] The front inner wall and the rear inner wall of the box body are both provided with limiting slide grooves extending along the left and right directions, and the rear inner wall of the box body is provided with an installation groove extending along the left and right directions. The limiting slide groove is located in the middle of the installation groove and is connected thereto, and the two slide plates are respectively located in the two limiting slide grooves and are slidably connected thereto along the up and down directions.

[0015] The effect is that by setting a limiting slide groove, the sliding direction of the slide plate can be limited to ensure that when the clamping assembly descends, the clamping mesh plate can accurately dock with the supporting mesh plate, thereby fixing the medicinal material slices on the supporting mesh plate.

[0016] The medicine lubricating mechanism also includes a pull-down telescopic rod, which has four pull-down telescopic rods and is respectively fixedly installed on both sides of the bottom of the two limiting slide grooves, and the telescopic ends of the pull-down telescopic rods are fixedly connected to the bottom end of the slide plate.

[0017] A square groove is provided in the middle of one end of the rotating shaft away from the clamping frame, and the medicine lubricating mechanism also includes a driving assembly, which includes a transmission shaft rotatably mounted on the rear wall of the box body and a clamping block slidably sleeved in the square groove, the transmission shaft corresponds to the rotating shaft with the square groove, a square clamping groove is provided at one end of the transmission shaft close to the rotating shaft, the top of the side of the clamping block close to the transmission shaft is an inclined surface inclined from bottom to top away from the transmission shaft, and an elastic member is connected between the other side of the clamping block and the square groove.

[0018] The effect is that, by providing the square card slot, the card block and the elastic member, after the clamping assembly is lowered, the rotating shaft can be quickly connected with the transmission shaft, so that the transmission shaft can drive the rotating shaft to rotate, and then drive the support frame and the clamping frame to rotate coaxially synchronously.

[0019] The medicine lubricating mechanism also includes a limiting component, which includes a first magnet fixedly installed at the bottom of the mounting groove and a second magnet fixedly installed at the bottom of the outer wall of the rotating shaft at one end away from the clamping frame. The first magnet and the second magnet are opposite to each other and have opposite magnetic poles at one end close to each other.

[0020] The effect is that by setting the first magnet and the second magnet with opposite magnetic poles close to each other at one end, the principle of opposite magnets attracting each other and the self-weight of the second magnet are utilized, so that after the rotating shaft stops rotating, the clamping mesh plate can be located above the supporting mesh plate and both are kept in a horizontal state, which is convenient for removing the supporting component after lubrication.

[0021] There are multiple medicine lubrication mechanisms which are evenly distributed along the up-and-down directions of the box body, and the multiple medicine lubrication mechanisms are independent of each other.

[0022] A steam distributor is arranged on the top of the medicine-lubricating mechanism, and an air extraction pipe is arranged on the bottom of the medicine-lubricating mechanism. One end of the air extraction pipe is communicated with the interior of the medicine-lubricating box.

[0023] The effect is that by setting multiple medicinal material moistening mechanisms which are independent of each other, the device can moisten multiple different medicinal materials simultaneously without worrying about the cross-contamination of the effective ingredients of the medicinal materials.

[0024] The steam distributor includes a steam pipe and a distribution plate fixedly installed on the top of the medicinal material moistening box and extending along the front-rear direction in the length direction. The bottom end of the distribution plate extends into the medicinal material moistening box and corresponds to the pressing frame, and one end of the steam pipe is connected to the distribution plate.

[0025] A bearing frame is fixedly installed on the inner wall of the medicinal material moistening box. The bearing frame is arranged parallel to the bottom surface of the medicinal material moistening box. An opening groove is formed on the front side of the box body, and the opening groove is communicated with the limit sliding groove. The support assembly slides into the medicinal material moistening box through the opening groove and is located on the top surface of the bearing frame.

[0026] The beneficial effects of the present invention are: By setting the support assembly and the pressing assembly, the medicinal material slices are evenly laid on the support mesh plate of the support assembly, and when laying, the medicinal material slices are prevented from stacking on top of each other. Then, the support assembly with the laid medicinal material slices is pushed into the medicinal material moistening box and located below the pressing assembly. Then, by controlling the pressing assembly to descend, the pressing mesh plate of the pressing assembly can press the medicinal material slices against the support mesh plate, thereby preventing the medicinal material slices from stacking on each other during moistening, which may cause some medicinal materials to not fully contact with the water vapor, resulting in uneven moistening of the medicinal materials. At the same time, during moistening, the support mesh plate and the pressing mesh plate are coaxially rotated by the rotating assembly, and the medicinal material slices can be flipped during moistening, so that both cut surfaces of the medicinal material slices can face the steam in turn, further ensuring the evenness of moistening. At the same time, by setting multiple medicinal material moistening mechanisms which are independent of each other, the device can moisten multiple different medicinal materials simultaneously without worrying about the cross-contamination of the effective ingredients of the medicinal materials, improving the moistening efficiency of the device for multiple different medicinal materials.

The multiple transmission gears 251 are respectively fixedly sleeved on the outer walls of the multiple rotating shafts 241, and the multiple transmission gears 251 are connected through the transmission belt 252.

[0039] refer to Figure 3 As shown, a square groove 2411 is provided in the middle of one end of one of the rotating shafts 241 away from the clamping frame 232, and the driving assembly 26 includes a transmission shaft 261 rotatably mounted on the rear wall of the box body 1 and a clamping block 263 slidably sleeved in the square groove 2411, the transmission shaft 261 corresponds to the rotating shaft 241 with the square groove 2411, and a square clamping groove 262 is provided at one end of the transmission shaft 261 close to the rotating shaft 241, and the top of the side of the clamping block 263 close to the transmission shaft 261 is an inclined surface inclined from bottom to top away from the transmission shaft 261, and an elastic member 264 is connected between the other side of the clamping block 263 and the square groove 2411, and the rear end of the transmission shaft 261 is drivingly connected to the output shaft of the external motor.

[0040] refer to Figure 6 and Figure 7As shown, there are four downward telescopic rods 27, which are respectively and fixedly installed on both sides of the bottom of the two limit sliding grooves 12. The telescopic end of the downward telescopic rod 27 is fixedly connected to the bottom end of the sliding plate 231. In this embodiment, the downward telescopic rod 27 is an electric telescopic rod. In other embodiments, the downward telescopic rod 27 can also be a hydraulic rod or a pneumatic telescopic rod. When moistening the medicine, start the downward telescopic rod 27 to drive the pressing assembly 23 to descend, so that the pressing assembly 23 fits with the supporting assembly 22, thereby fixing the medicinal material slices.

[0041] The limiting assembly 28 includes a first magnet 281 fixedly installed at the bottom of the installation groove 13 and a second magnet 282 fixedly installed at the bottom of the outer wall of the end of the rotating shaft 241 away from the pressing frame 232. The first magnet 281 and the second magnet 282 face each other and the magnetic poles of the mutually approaching ends are opposite. There are multiple first magnets 281 and multiple second magnets 282. The multiple second magnets 282 are respectively fixedly installed on the multiple rotating shafts 241.

[0042] The implementation principle of the embodiment of the present invention is as follows: When moistening the medicine, place the medicinal material slices on the supporting mesh plate 223, and then push the supporting assembly 22 into the moistening box 21 in the box body 1 through the opening groove 11. At this time, the supporting assembly 22 falls onto the bearing frame 29, and the rear side of the square frame 221 is clamped in the opening groove 11 and seals it. Then start the downward telescopic rod 27 to drive the pressing assembly 23 to descend. As the pressing assembly 23 descends, the insertion shaft 244 on the rotating shaft 241 is inserted into the insertion hole 2421, and at the same time, the split shaft 242 is clamped into the split groove 243. At this time, the split shaft 242 and the rotating shaft 241 are combined into a complete rotating shaft. At the same time, the pressing mesh plate 233 also presses the medicinal material slices on the supporting mesh plate 223, and then evacuate the moistening box 21 through the air extraction pipe 4.

[0043] After the pressing assembly 23 finishes descending, at this time, the rotating shaft 241 is coaxial with the transmission shaft 261. The clamping block 263 in the square sliding groove 2411 slides into the square clamping groove 262 under the action of the elastic member 264, so that the rotating shaft 241 can rotate synchronously with the transmission shaft 261. Then start the external motor, and drive all the supporting frames 222 and the pressing frames 232 to rotate around the rotating shaft 241 through the transmission shaft 261 and the transmission assembly 25. At the same time, evenly introduce steam into the moistening box 21 through the steam distributor 3. At this time, the steam diffuses from top to bottom under the action of the vacuum and will penetrate the medicinal material slices, thereby completing the moistening of the medicinal material slices.

[0044] After the medicine moistening is completed, control the transmission shaft 261 to stop rotating. At this time, under the action of the first magnet 281 and the second magnet 282, after the rotating shaft 241 stops rotating, it can ensure that the pressing frame 232 is located above the support frame 222 and both are in a horizontal state. At this time, start the downward telescopic rod 27 to drive the pressing assembly 23 to rise. At this time, under the cooperation of the inclined surface provided on the clamping block 263 and the square clamping groove 262, the clamping block 263 is pressed back into the square sliding groove 2411, so that the pressing assembly 23 can rise smoothly. As the pressing assembly 23 rises, the split shaft 242 and the rotating shaft 241, as well as the insertion shaft 244 and the insertion hole 2421, are separated from each other, so that the support assembly 22 can be pulled out of the box body 1.

[0045] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
