Description

Technical Field

[0001] The present application relates to the field of Chinese medicine preparation, and in particular to a Chinese medicine liquid filtering device. Background Art

[0002] In the preparation process of Chinese medicine liquid, the ingredients need to be prepared first, and the required Chinese medicines are mixed together in a certain proportion, and then water is added for steaming, so that the medicinal properties of the Chinese medicine enter the water to form a liquid medicine. After the steaming is completed, the residue is filtered out to obtain the required Chinese medicine liquid.

[0003] Traditional Chinese medicine liquid is usually filtered using a filter, and after filtering, the residue will be treated as garbage; but in fact, the residue has a certain water absorption capacity, that is, there will still be some liquid medicine in the residue, which will cause waste of the traditional Chinese medicine liquid. Summary of the invention

[0004] In order to solve the above-mentioned problem and allow the medicinal liquid in the medicinal residue to seep out to prevent waste, the present application provides a Chinese medicinal liquid filtering device.

[0005] The Chinese medicine liquid filtering device provided in this application adopts the following technical solution:

[0006] The Chinese medicine liquid filtering device comprises a filter box, a filter hole plate is arranged in the horizontal direction in the filter box, the filter box is located above the filter hole plate and is rotatably connected to an extrusion roller, and mounting grooves are opened in the horizontal direction on two opposite inner side walls of the filter box, one of which is provided with a rack, the length direction of the rack is consistent with the length direction of the mounting groove, one end of the extrusion roller is fixedly connected to a first connecting shaft, and the other end of the extrusion roller is fixedly connected to a second connecting shaft, a linkage gear is coaxially arranged on the first connecting shaft, and the linkage gear is meshed with the rack; screw rods are rotatably connected in the two mounting grooves, the length direction of the screw rods is consistent with the length direction of the rack, and moving blocks are threadedly connected on the two screw rods, one of which is sleeved on the circumference of the first connecting shaft and forms a rotational fit, and the other moving block is sleeved on the circumference of the second connecting shaft and forms a rotational fit, and a first motor is fixedly installed on the outer wall of the filter box, and the first motor drives the screw rod to rotate.

[0007] By adopting the above technical scheme, the Chinese medicine liquid after cooking is poured into the filter box. Under the action of the filter hole plate, the medicine residue will remain on the upper side of the filter hole plate. At this time, the first motor drives the screw to rotate. When the screw rotates, it will drive the moving block to slide along the length direction of the installation groove, that is, drive the extrusion roller to slide on the filter mesh plate. At the same time, the linkage gear rotates due to running on the rack, driving the first connecting shaft to rotate, that is, realizing the rotation of the extrusion roller; the extrusion roller rolls on the filter hole plate to squeeze the medicine residue, so that the medicine liquid in the medicine residue seeps out to prevent waste.

[0008] Preferably, the filter box is located in the installation groove where the rack is located and a driving wheel is rotatably arranged, and a connecting groove is radially opened on the driving wheel, and the connecting groove is open; a plug-in portion is formed at the end of the first connecting shaft, and the plug-in portion is plugged into the connecting groove to form a coaxial rotation fit, and a second motor is installed on the filter box, and the output shaft of the second motor is coaxially fixed with the driving wheel; a counterweight portion is formed on the driving wheel, and in an initial state, under the action of the counterweight portion, the connecting groove is horizontal; the linkage gear and the first connecting shaft are connected by a first ratchet and pawl mechanism to form a unidirectional rotation, when the first connecting shaft rotates, the linkage gear does not rotate, and when the linkage gear rotates, it drives the first connecting shaft to rotate; a stirring column is provided on the peripheral side of the extrusion roller for disturbing the medicine liquid; the filter plate is lifted and arranged in the filter box.

[0009] By adopting the above technical scheme, in the initial state, the stirring column extends out of the surface of the squeezing roller, and the filter hole plate is in a descending state, and there is a certain height difference between it and the squeezing roller, avoiding the rotation trajectory of the stirring column; when the Chinese medicine liquid is poured into the filter box, the filter hole plate will decelerate the medicine liquid, that is, in the initial state, the medicine liquid will be filtered slowly, and the second motor drives the driving wheel to rotate, driving the first connecting shaft to rotate, realizing the rotation of the squeezing roller, and the squeezing roller will drive the stirring column to rotate together, and the linkage gear does not move at this time; when the Chinese medicine liquid is poured into the filter box, due to the existence of the filter hole plate, the medicine liquid will not immediately enter the lower side of the filter box, that is, the filter hole plate causes the medicine liquid to be filtered slowly, then in this process, there will be a situation where the medicine residue blocks the filter hole plate, and the rotation of the squeezing roller and the stirring column is used to stir the medicine liquid on the upper side of the filter hole plate , disturbing the medicine liquid to make the medicine residue flow, preventing the medicine residue from settling on the filter hole plate, blocking the hole plate and affecting the filtering effect; after the medicine liquid is filtered, the second motor stops working, under the action of the counterweight part, when the driving wheel is stationary, the connecting groove is horizontal, and then the stirring column slides to the inside of the extrusion roller, and is in a state of not protruding from the surface of the extrusion roller, and the filter hole plate rises and contacts the surface of the extrusion roller; at this time, the first motor runs, driving the screw rod to rotate, and the screw rod will drive the moving block to slide in the installation groove, and the direction of movement of the moving block is the direction of the opening of the connecting groove, and the moving block drives the first connecting shaft to slide in the horizontal direction, that is, the extrusion roller will slide in the horizontal direction, because the linkage gear runs on the rack, so the linkage gear will drive the extrusion roller to rotate through the first connecting shaft, that is, the extrusion roller rolls on the filter hole plate, squeezes the medicine residue, and causes the medicine liquid to seep out.

[0010] Preferably, the plug-in portion is rotatably matched with the first connecting shaft, and a square shaft portion is formed at one end of the plug-in portion away from the first connecting shaft, and the square shaft portion is plug-fitted with the connecting groove, and the plug-in portion and the first connecting shaft are connected by a second ratchet and pawl mechanism to form a one-way rotational match; when the plug-in portion rotates, the first connecting shaft rotates accordingly, and when the first connecting shaft rotates, the plug-in portion does not rotate.

[0011] By adopting the above technical scheme, the square shaft part and the connecting groove are plugged in and matched to form a coaxial rotation fit. When the driving wheel rotates to drive the plug-in part to rotate, the first connecting shaft rotates accordingly to realize the rotation of the extrusion roller. When the driving wheel stops rotating, the screw rotates. At this time, the linkage gear drives the connecting shaft to rotate, while the plug-in part does not move. The plug-in part will only slide laterally with the first connecting shaft and fall out of the connecting groove; when the extrusion roller moves from one end of the filter box to the other end, the screw rotates in the opposite direction. At this time, the linkage gear reverses, and the first connecting shaft does not rotate. The extrusion roller as a whole will only slide laterally in the filter box.

[0012] Preferably, a sliding groove is provided on the side of the rack, and the sliding groove is consistent with the length direction of the rack. The rack is located in the sliding groove and is slidably connected with a sliding block. A rotating ring seat is provided on the sliding block. The rotating ring seat is sleeved on the circumferential side of the first connecting shaft, and the rotating ring seat is rotatably matched with the first connecting shaft, and the linkage gear is rotatably connected to the rotating ring seat; the first ratchet pawl mechanism includes a first pawl, a first ratchet wheel and a first spring sheet, the first pawl is hinged on the side of the linkage gear close to the extrusion roller, the first ratchet wheel is coaxially fixed on the first connecting shaft, the first pawl abuts against the teeth of the first ratchet wheel, the first spring sheet is hinged on the linkage gear, and the end of the first spring sheet abuts against the first pawl.

[0013] By adopting the above technical solution, when the driving wheel drives the first connecting shaft to rotate, the first ratchet on the first connecting shaft will rotate relative to the first pawl, and the first pawl will not move, that is, the linkage gear will not rotate; when the moving block drives the first connecting shaft to slide in the horizontal direction, the first connecting shaft will drive the rotating ring seat to slide on the rack, so that the linkage gear moves with the sliding of the first connecting shaft. During the movement of the linkage gear, it will walk on the rack and rotate. The linkage gear drives the first ratchet to rotate through the first pawl, thereby realizing the rotation of the first connecting shaft.

[0014] Preferably, the second ratchet pawl mechanism includes a second pawl, a second ratchet and a second spring plate, a rotating ring plate is coaxially fixed on the plug-in portion, the second pawl is hinged on the rotating ring plate, the second ratchet is coaxially fixed on the first connecting shaft, the second pawl abuts against the teeth of the second ratchet, the second spring plate is hinged on the rotating ring plate, and the end of the second spring plate abuts against the second pawl.

[0015] By adopting the above technical solution, when the driving wheel drives the plug-in part to rotate, the second pawl will drive the second ratchet to rotate, thereby realizing the synchronous rotation of the first connecting shaft. Because the teeth on the second ratchet are helical teeth, if the rotating ring plate does not rotate, when the first connecting shaft drives the second ratchet to rotate in the same direction, the second pawl will not rotate therewith, that is, the plug-in part will not rotate therewith.

[0016] Preferably, the extrusion roller is hollow and forms a hollow groove, the extrusion roller is provided with two connecting plates in the hollow groove, the two connecting plates are arranged opposite to each other, the stirring column is arranged on the connecting plate, the stirring column and the extrusion roller are plugged and slidably matched, the extrusion roller is provided with a linkage block between the two connecting plates, the linkage block slides in the extrusion roller along the horizontal direction, the second connecting shaft is provided with a through groove along its own length direction, the through groove is connected with the hollow groove, the linkage block is plugged and slidably matched with the through groove, and the end of the linkage block is arranged to pass through the second connecting shaft; the linkage block is provided with a driving groove, the side wall of the driving groove is formed with a first wedge-shaped surface, a wedge block is provided on the connecting plate, and the wedge block is close to the linkage A second wedge-shaped surface is formed on one side of the moving block; a compression spring is arranged in the through groove of the second connecting shaft, and the compression spring is sleeved on the circumference of the linkage block; an abutment ring plate is integrally formed on the linkage block, and the abutment ring plate is located in the hollow groove; the compression spring is located on the side of the abutment ring plate close to the hollow groove; one end of the compression spring is connected to the abutment ring plate, and the other end of the compression spring is connected to the notch of the through groove; in the initial state, the wedge block is disengaged from the driving groove, and the stirring column extends out of the extrusion roller arrangement; a driving member is arranged in the filter box to drive the linkage block to slide toward the inside of the extrusion roller, and when the driving member drives the linkage block to slide, the second wedge surface of the wedge block enters the driving groove along the first wedge surface, and the stirring column slides toward the inside of the extrusion roller.

[0017] By adopting the above technical scheme, in the initial state, the stirring column is arranged to extend out of the surface of the squeezing roller. When the squeezing roller rotates, the stirring column can disturb the Chinese medicine liquid to prevent the medicine residue from settling on the surface of the filter hole plate to prevent blockage; after the Chinese medicine liquid is filtered, the squeezing roller stops rotating, and the filter hole plate rises at this time. At the same time, the driving member drives the linkage block to slide, and the second wedge surface of the wedge block enters the driving groove along the first wedge surface, and the stirring column slides into the squeezing roller. If the stirring column extends out of the surface of the squeezing roller, the squeezing roller cannot extrude the medicine residue when rolling; when the squeezing operation is completed, the filter hole plate descends and resets, and at the same time, the linkage block slides and resets under the action of the compression spring, and the wedge block is separated from the driving groove, that is, the wedge block will drive the connecting plate to slide backward, and the stirring column extends out of the surface of the squeezing roller.

[0018] Preferably, lifting blocks are provided on both sides of the filter plate, and receiving grooves are opened in the two side walls of the filter box. The filter box is provided with driving cylinders in the two receiving grooves. The driving cylinders are vertically arranged, and the piston rod ends of the driving cylinders are fixedly connected to the corresponding lifting blocks.

[0019] By adopting the above technical solution, the driving cylinder is operated and the piston rod is extended and retracted, so that the filter plate can be raised and lowered. When the filtration is completed, the liquid level of the medicine solution is lower than the lowest end of the lifting tank.

[0020] Preferably, the driving member is configured as a driving plate, which is fixedly connected to the piston rod of one of the driving cylinders, and the driving plate extends into the mounting groove. A third wedge-shaped surface is formed on the upper side of the driving plate, and a spherical portion is formed at the end of the linkage block away from the extrusion roller. When the piston rod of the driving cylinder is extended, the third wedge-shaped surface of the driving plate abuts against the spherical portion and causes the linkage block to slide toward the inner side of the extrusion roller; when the extrusion roller slides in the horizontal direction, the spherical portion of the linkage block always abuts against the driving plate and forms a rotational fit.

[0021] By adopting the above technical solution, when the driving cylinder drives the filter hole plate to rise, the driving plate rises, and the third wedge surface of the driving plate abuts against the spherical part of the linkage block and makes the linkage block slide toward the inside of the extrusion roller. At this time, with the cooperation of the linkage block and the wedge block, the stirring column will enter the extrusion roller; then the extrusion roller can roll to extrude the drug residue and seep out the drug liquid. During this process, the spherical part of the linkage block always abuts against the driving plate, and the spherical part rotates and slides on the surface of the driving plate.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. After filtering the Chinese medicine liquid by the filter plate, the medicine residue will accumulate on the filter plate. The first motor is used to drive the screw rod to rotate, so that the moving block drives the extrusion roller to slide in the horizontal direction. During the sliding process, due to the meshing of the linkage gear and the rack, the linkage gear rotates, driving the first connecting shaft to rotate, that is, the extrusion roller rolls, and then the medicine residue is squeezed, so that the residual medicine liquid in the medicine residue seeps out, preventing waste;

[0024] 2. When the Chinese medicine liquid is poured into the filter box, it will be filtered slowly. During this process, the medicine residue may block the filter plate. The driving wheel is used to drive the first connecting shaft to rotate. At this time, the linkage gear does not rotate, that is, the squeezing roller only rotates. The stirring column on the squeezing roller is used to disturb the Chinese medicine liquid, so that the medicine residue flows in the medicine liquid, which helps to prevent the medicine residue from blocking the filter plate.

[0025] 3. When the Chinese medicine solution is filtered to the lower side of the filter plate, the filter plate rises a distance. During the rising process, the driving plate causes the linkage block to slide toward the inside of the extrusion roller, causing the stirring column to slide to the inside of the extrusion roller, and then the extrusion roller can roll to extrude the medicine residue.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The embodiment of the present application discloses a Chinese medicine liquid filtering device.

[0037] Reference Figure 1 and Figure 2 The Chinese medicine liquid filtering device includes a filter box 1, in which a filter hole plate 2 is horizontally arranged, and a plurality of filter holes are formed on the filter hole plate 2. The filter box 1 is located on the upper side of the filter hole plate 2 and is rotatably connected to an extrusion roller 3. In an initial state, the extrusion roller 3 is located on one side of the filter box 1; the filter box 1 is provided with mounting grooves 11 on two side walls corresponding to the two ends of the extrusion roller 3, and the length direction of the mounting groove 11 is horizontally arranged. The filter box 1 is located in one of the mounting grooves 11 and a rack 12 is laid, and the length direction of the rack 12 is consistent with the length direction of the mounting groove 11; a first connecting shaft 31 is integrally formed at one end of the extrusion roller 3, and a second connecting shaft 32 is integrally formed at the other end of the extrusion roller 3. A linkage gear 13 is coaxially arranged on the first connecting shaft 31, and the linkage gear 13 is meshed with the rack 12.

[0038] The filter box 1 is located in two mounting grooves 11 and is rotatably connected to a screw rod 14. The length direction of the screw rod 14 is consistent with the length direction of the rack 12. Moving blocks 15 are threadedly connected to the two screw rods 14. One of the moving blocks 15 is sleeved on the circumference of the first connecting shaft 31 and forms a rotational fit with the first connecting shaft 31. The other moving block 15 is sleeved on the circumference of the second connecting shaft 32 and forms a rotational fit with the second connecting shaft 32. Two first motors 16 are fixedly connected to the outer wall of the filter box 1. The two first motors 16 correspond to the two screw rods 14 one by one, and the output shaft of the first motor 16 is fixedly connected to the corresponding end of the screw rod 14.

[0039] After the Chinese medicine liquid is boiled, it is poured into the filter box 1. Under the action of the filter hole plate 2, the medicine residue will accumulate on the filter hole plate 2. At this time, the first motor 16 drives the screw rod 14 to rotate. The rotation of the screw rod 14 drives the moving block 15 to slide in the horizontal direction, and drives the linkage gear 13 to move on the rack 12 through the first connecting shaft 31. The linkage gear 13 rotates on the rack 12, and then drives the squeezing roller 3 to rotate through the first connecting shaft 31, that is, the squeezing roller 3 rolls on the filter hole plate 2 to squeeze the medicine residue, so that the residual medicine liquid in the medicine residue seeps out to prevent waste.

[0040] Reference Figure 2 and Figure 3 The filter box 1 is located in the installation groove 11 where the rack 12 is located, and a driving wheel 4 is rotatably arranged. A connecting groove 41 is radially opened on the driving wheel 4, and the connecting groove 41 is open on the driving wheel 4. A plug-in portion 311 is formed at the end of the first connecting shaft 31, and the plug-in portion 311 is plugged and matched with the connecting groove 41 to form coaxial rotation; a second motor 17 is installed on the outer wall of the filter box 1, and the output shaft of the second motor 17 is coaxially fixed with the driving wheel 4; the linkage gear 13 and the first connecting shaft 31 are connected by a first ratchet pawl mechanism 5 to form a unidirectional rotation. When the first connecting shaft 31 rotates, the linkage gear 13 does not rotate, and when the linkage gear 13 rotates, the first connecting shaft 31 rotates accordingly; when the second motor 17 runs, it drives the driving wheel 4 to rotate, and the driving wheel 4 drives the first connecting shaft 31 to rotate, and at this time the linkage gear 13 does not rotate. In addition, a counterweight 42 is formed on the driving wheel 4, and the counterweight 42 enables the connection groove 41 of the driving wheel 4 to always remain in a horizontal state, and the opening of the connection groove 41 faces the direction in which the squeezing roller 3 is to slide. A stirring column 33 is provided on the peripheral side of the squeezing roller 3 to disturb the liquid medicine, and the filter plate 2 is provided in the filter box 1. In the initial state, the stirring column 33 extends out of the surface of the squeezing roller 3, and there is a certain height difference between the filter plate 2 and the squeezing roller 3 to avoid the stirring column 33.

[0041] When the Chinese medicine liquid is poured into the filter box 1, since the filter hole plate 2 acts as a buffer for the Chinese medicine liquid, it takes a certain amount of time for the Chinese medicine liquid to be completely filtered to the lower side of the filter hole plate 2. During this process, there may be a phenomenon that the filter hole plate 2 is blocked by the drug residue. The second motor 17 is used to drive the driving wheel 4 to rotate, and the driving wheel 4 drives the extrusion roller 3 to rotate. The stirring column 33 can be used to disturb the Chinese medicine liquid to make the medicine liquid flow, that is, to make the drug residue flow, to prevent the drug residue from settling and blocking the filter hole plate 2, thereby affecting the filtration speed. Afterwards, the second motor 17 stops running, and under the action of the counterweight 42 of the driving wheel 4, the connecting groove 41 returns to a horizontal state. When all the medicinal liquid is filtered to the lower side of the filter hole plate 2, the liquid level of the medicinal liquid will not be higher than the filter hole plate 2. At this time, the filter hole plate 2 rises, and the stirring column 33 slides to the inner side of the extrusion roller 3. Then the first motor 16 drives the screw 14 to rotate, and the first connecting shaft 31 and the second connecting shaft 32 drive the extrusion roller 3 to slide, and the linkage gear 13 moves on the rack 12 and rotates, that is, drives the extrusion roller 3 to rotate, and the extrusion roller 3 rolls on the filter hole plate 2 to achieve the extrusion of the medicinal residue.

[0042] The plug-in portion 311 is configured as a plug-in block, and the plug-in portion 311 and the first connecting shaft 31 are matched through the shaft hole to form a rotational fit, and a square shaft portion 312 is formed at the end of the plug-in portion 311 away from the first connecting shaft 31, and the square shaft portion 312 is plug-matched with the connecting groove 41 to form a coaxial rotation; the plug-in portion 311 and the first connecting shaft 31 are connected through the second ratchet and pawl mechanism 6 to form a one-way rotational fit; when the plug-in portion 311 rotates, the first connecting shaft 31 rotates accordingly, and when the first connecting shaft 31 rotates, the plug-in portion 311 does not rotate, that is, when the driving wheel 4 drives the plug-in portion 311 to rotate, the first connecting shaft 31 rotates to drive the extrusion roller 3 to rotate; when the screw rod 14 rotates and the linkage gear 13 drives the first connecting shaft 31 to rotate, the plug-in portion 311 does not rotate, and the plug-in portion 311 performs horizontal sliding motion at this time.

[0043] Reference Figure 2 and Figure 4 A sliding groove 121 is provided on the side of the rack 12, and the length direction of the sliding groove 121 is consistent with the length direction of the rack 12. The rack 12 is located in the sliding groove 121 and is slidingly connected with a sliding block 122. A rotating ring seat 123 is fixedly connected to the sliding block 122. The rotating ring seat 123 is sleeved on the first connecting shaft 31 and rotatably cooperates with the first connecting shaft 31. The linkage gear 13 is rotatably connected to the rotating ring seat 123. In fact, the linkage gear 13 and the rotating ring seat 123 are sleeved on the circumferential side of the first connecting shaft 31 through a shaft sleeve.

[0044] Reference Figure 2 , Figure 3 and Figure 5The first ratchet pawl mechanism 5 includes a first pawl 51, a first ratchet wheel 52 and a first elastic piece 53. The first pawl 51 is hinged on the side of the linkage gear 13 close to the squeezing roller 3. The first ratchet wheel 52 is coaxially fixed on the first connecting shaft 31. The teeth of the first ratchet wheel 52 are located on the inner side. The first pawl 51 abuts against the teeth of the first ratchet wheel 52. The first elastic piece 53 is hinged on the linkage gear 13, and the end of the first elastic piece 53 abuts against the first pawl 51. When the screw rod 14 rotates, the moving block 15 drives the squeezing roller 3 to slide. At this time, the first connecting shaft 31 will also drive the rotating ring seat 123 to slide on the rack 12, that is, the linkage gear 13 walks and rolls on the rack 12. The linkage gear 13 drives the first ratchet wheel 52 to rotate through the first pawl 51, so as to realize the rotation of the first connecting shaft 31, that is, the rotation of the squeezing roller 3.

[0045] Reference Figure 2 , Figure 3 and Figure 6 The second ratchet pawl mechanism 6 includes a second pawl 61, a second ratchet wheel 62 and a second elastic piece 63. The plug-in portion 311 is coaxially fixed with a rotating ring plate 313. The second pawl 61 is hinged on the rotating ring plate 313. The second ratchet wheel 62 is coaxially fixed on the first connecting shaft 31. The teeth of the second ratchet wheel 62 are located on the inner side. The second pawl 61 abuts against the teeth of the second ratchet wheel 62. The second elastic piece 63 is hinged on the rotating ring plate 313, and the end of the second elastic piece 63 abuts against the second pawl 61. When the driving wheel 4 drives the plug-in portion 311 to rotate, the second pawl 61 drives the second ratchet wheel 62 to rotate, so as to realize the rotation of the first connecting shaft 31, that is, to realize the rotation of the squeezing roller 3. When the plug-in portion 311 does not rotate, when the first connecting shaft 31 rotates, it will not drive the plug-in portion 311 to rotate.

[0046] By using the first ratchet and pawl mechanism 5 and the second ratchet and pawl mechanism 6, when the second motor 17 is running, the plug-in portion 311 drives the squeezing roller 3 to rotate through the second ratchet and pawl mechanism 6, and the linkage gear 13 does not rotate at this time; when the second motor 17 stops, the first motor 16 runs, the squeezing roller 3 slips, the linkage gear 13 moves and rotates on the rack 12, and the linkage gear 13 drives the first connecting shaft 31 to rotate through the first ratchet and pawl mechanism 5, and the plug-in portion 311 does not rotate at this time, because the square shaft portion 312 on the plug-in portion 311 is plugged into the connecting groove 41, so if the plug-in portion 311 rotates, the first connecting shaft 31 cannot slip, and the plug-in portion 311 does not rotate, and during the rolling process of the squeezing roller 3, the plug-in portion 311 can be smoothly disengaged from the connecting groove 41. When the squeezing roller 3 rolls to the other end of the filter box 1, the first motor 16 reverses, and the linkage gear 13 rotates in the opposite direction. Under the action of the pawl of the first ratchet 52, the first connecting shaft 31 does not rotate, that is, the squeezing roller 3 only performs sliding motion. At this time, the squeezing roller 3 can collect the drug residues, and the drug residues will move to one side of the filter box 1 with the squeezing roller 3 to prevent the subsequent filtering operation from being affected. Under the action of the counterweight 42, the driving wheel 4 always keeps the connecting groove 41 horizontal, which can ensure that after the squeezing roller 3 is reset, the plug-in portion 311 can be smoothly plugged and matched with the connecting groove 41.

[0047] Reference Figure 2 , Figure 7 and Figure 8The extrusion roller 3 is hollow and has a hollow groove 34. The extrusion roller 3 is provided with two connecting plates 7 in the hollow groove 34. The two connecting plates 7 are arranged opposite to each other and slide in the extrusion roller 3. The stirring column 33 is fixedly connected to the connecting plates 7. The weights of the two connecting plates 7 are different. In the initial state, the heavier connecting plate 7 is at the lower side. The stirring column 33 is plugged and slidably matched with the surface of the extrusion roller 3. A return spring 331 is sleeved on the stirring column 33. One end of the return spring 331 abuts against the connecting plate 7, and the other end of the return spring 331 abuts against the inner wall of the extrusion roller 3. The extrusion roller 3 is provided with a linkage block 8 between the two connecting plates 7. The linkage block 8 slides in the extrusion roller 3 in the horizontal direction. The second connecting shaft 32 is provided with a through groove 321 along its length direction. The through groove 321 is connected with the hollow groove 34. The linkage block 8 slides with the through groove 321, and one end of the linkage block 8 passes through the through groove 321 to the outside of the second connecting shaft 32. The linkage block 8 is provided with a driving groove 81, and a first wedge-shaped surface 82 is formed on the side wall of the driving groove 81. The two connecting plates 7 are integrally formed with a wedge block 71 on the side close to each other, and a second wedge-shaped surface 72 is formed on the side of the wedge block 71 close to the linkage block 8. In the initial state, the stirring column 33 extends out of the surface of the squeezing roller 3, and the wedge block 71 and the driving groove 81 are in a disengaged state. When the linkage block 8 slides toward the inner side of the squeezing roller 3, the wedge block 71 enters the driving groove 81 through the first wedge-shaped surface 82 and the second wedge-shaped surface 72, and the end of the stirring column 33 retracts into the squeezing roller 3.

[0048] The second connecting shaft 32 is located in the through groove 321 and is provided with a compression spring 322. The compression spring 322 is sleeved on the circumferential side of the linkage block 8. The linkage block 8 is integrally formed with an abutment ring plate 83. The abutment ring plate 83 is located in the through groove 321. The compression spring 322 is located on the side of the abutment ring plate 83 close to the hollow groove 34. One end of the compression spring 322 is connected to the abutment ring plate 83, and the other end of the compression spring 322 is connected to the notch at the connection point between the through groove 321 and the hollow groove 34. A driving member for driving the linkage block 8 to slide into the squeezing roller 3 is provided in the filter. The driving member is provided as a driving plate 9. The driving plate 9 is lifted and lowered in the filter box 1. A third wedge-shaped surface 91 is formed on the upper side of the driving plate 9. A spherical portion 84 is formed at the end of the linkage block 8 extending out of the second connecting shaft 32. When the driving plate 9 rises, the third wedge-shaped surface 91 abuts against the spherical portion 84, and the linkage block 8 slides into the squeezing roller 3, thereby allowing the stirring column 33 to retract into the squeezing roller 3. When the squeezing roller 3 slides and rotates in the horizontal direction, the spherical portion 84 of the linkage block 8 always abuts against the driving plate 9 and forms a rotational fit. After the driving plate 9 is lowered, under the action of the compression spring 322, the linkage block 8 is reset, and the stirring column 33 extends out of the squeezing roller 3.

[0049] Both sides of the filter plate 2 are integrally formed with lifting blocks 21, and the two side walls of the filter box 1 are provided with lifting grooves 18 at the positions corresponding to the lifting blocks 21. Both side walls of the filter box 1 are provided with receiving grooves 19, and the lifting grooves 18 are connected with the receiving grooves 19. The lifting blocks 21 extend into the receiving grooves 19 through the lifting grooves 18. The filter box 1 is located in the two receiving grooves 19 and is fixedly installed with driving cylinders 10. The driving cylinders 10 are arranged vertically upward, and the two driving cylinders 10 correspond to the two lifting blocks 21 one by one. The piston rods of the driving cylinders 10 are fixedly connected to the corresponding lifting blocks 21. The driving cylinders 10 are operated, and the piston rods are extended and retracted, which drives the lifting blocks 21 to rise and fall, thereby realizing the lifting and lowering movement of the filter plate 2. In practice, when the filtering operation is completed, the liquid level of the Chinese medicine liquid is lower than the lowest end of the lifting grooves 18.

[0050] In addition, the lower side of the driving plate 9 is fixedly connected to the piston rod end of the driving cylinder 10, and the driving plate 9 extends from the receiving groove 19 into the mounting groove 11. When the filter plate 2 rises, the driving plate 9 rises accordingly, and finally the stirring column 33 is retracted into the squeezing roller 3 to prevent the stirring column 33 from interfering with the rise of the filter plate 2.

[0051] The implementation principle of the medicinal liquid filtering device in the embodiment of the present application is as follows: the Chinese medicine liquid is poured into the filter box 1, and the filter hole plate 2 will filter the medicinal residue. During the filtering process, because the filter hole plate 2 plays a buffering role on the Chinese medicine liquid, the Chinese medicine liquid will remain on the upper side of the filter hole plate 2 for a period of time. At this time, the driving wheel 4 is used to drive the squeezing roller 3 to rotate, and the stirring column 33 is used to disturb the Chinese medicine liquid, that is, to make the medicinal residue flow, so as to prevent the medicinal residue from clogging the filter hole plate 2 and affecting the filtering efficiency; after the filtering is completed, the screw 14 rotates, and the moving block 15 drives the first connecting shaft 31 and the second connecting shaft 32 to move synchronously, that is, drives the squeezing roller 3 to move in the horizontal direction. At this time, the linkage gear 13 walks on the rack 12 and rotates, driving the squeezing roller 3 to rotate, that is, the squeezing roller 3 rolls on the filter hole plate 2 to squeeze the medicinal residue and squeeze out the residual medicinal liquid therein to prevent waste.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
