Description

Technical Field

[0001] The invention belongs to the field of automatic decoction of traditional Chinese medicine, and in particular relates to a cover lifting structure of an automatic production line of traditional Chinese medicine. Background Art

[0002] In the prior art, automated equipment is increasingly used in the decoction process of traditional Chinese medicine, for example, a decoction device for decocting medicinal materials, a filling device for filling liquid medicine, and a lifting device for supporting the inner pot of a decoction pot. The lengthy process of decoction of traditional Chinese medicine is split up by a number of devices that perform specific processes, which greatly improves the efficiency of each process of decoction of traditional Chinese medicine and the number of products that can be processed simultaneously. Put Chinese medicine pieces and water in the decoction pot, and then grab and carry the decoction pot by a robot, so as to realize the steps of automatic decoction of traditional Chinese medicine, automatic removal of drug residues, automatic pouring of liquid medicine and filling, etc., saving manpower and improving production efficiency. In the automated decoction system of traditional Chinese medicine, the robot carries the medicine pot between various devices and connects various process flows.

[0003] Before the decoction pot is sent into the extrusion device for the process of extruding the medicinal residue, the lid of the decoction pot needs to be opened and moved aside to open the pot mouth so that the part to be squeezed into the decoction pot can smoothly penetrate into the decoction pot, and then the remaining medicinal residue in the inner pot is squeezed to completely precipitate the medicinal liquid.

[0004] In the prior art, the pot cover is usually removed manually, so the automatically operated mechanical equipment will pose a great threat to the personal safety of workers. If the workers are not familiar with the workshop environment, there is a high probability that the running equipment will damage their health, and the workers are prone to fatigue at work. If the pot cover is not removed in time, the structural parts of the mechanical equipment will collide with the decoction pot, causing the automatic decoction process to stagnate. It is difficult to meet the speed requirements of the automatic decoction process by relying on manual labor, which will greatly reduce the efficiency and stability of the automatic decoction process.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a cover-lifting structure for an automated production line of traditional Chinese medicine, so as to realize the action of quickly and reliably removing the cover of a medicine-decocting pot through an automated mechanical device, thereby improving the efficiency and stability of the automated medicine-decocting process.

[0010] Furthermore, the first connecting frame of the flip cover structure includes an extended rib having a long side and a short side, the short side is connected to the flip cover sliding block, the cantilever end is formed by the part of the long side of the extended rib protruding from the short side, and the telescope body is connected to the end on the long side and is separated from the feed assembly by a certain distance.

[0011] Furthermore, the long side of the elongated rib is connected to the second connecting frame of the flip cover structure, and the telescopic device body is connected to the plane of the second connecting frame of the flip cover structure in the shape of a long strip.

[0012] The middle part of the second connecting frame of the flip cover structure in the width direction is connected to the long side of the lengthened rib plate and is perpendicular to the lengthened rib plate.

[0013] Furthermore, the length of the second connecting frame of the flip cover structure is greater than the long side of the lengthened rib plate, and one end thereof protrudes beyond the lengthened rib plate toward the cantilever end and is connected to the telescopic device body.

[0014] Furthermore, a first lifter having a fixed part and a movable part is provided at the end of the second connecting frame of the flip cover structure, and the first lifter enables the telescopic device body to be movably connected to the second connecting frame of the flip cover structure.

[0017] The fixing part of the first lifter is connected to the vertical connecting plate of the first lifter, and the movable part thereof passes through the second connecting frame of the flip cover structure and is connected to the telescopic device body.

[0018] Furthermore, the clamping assembly includes two telescopic movable side plates movably connected to the telescopic main body, the telescopic movable side plates move along a horizontal straight line direction and are each connected to a pot cover clamping claw.

[0019] Furthermore, the pot cover claw has two mutually perpendicular flat edges, one of which is connected to the movable side plate of the telescopic device, and the edge of the other is provided with an arc-shaped notch.

[0020] The arc-shaped notches of the two pot cover claws are arranged to face each other and be aligned.

The movable distance of the lid-lifting sliding block is greater than the diameter of the medicine decoction pot, which can ensure that the lid claws completely let the lid go out of the pot mouth of the medicine decoction pot, so as to achieve the purpose of moving the extrusion structure to the top of the medicine decoction pot to smoothly extrude the medicine residue.

[0026] 2. The lid-lifting structure realizes the purpose of using the lid claw to completely remove the lid from the decoction pot and clear the pot mouth, replacing manual labor, solving the problem of manual fatigue and error-proneness due to repetitive labor, improving the speed of taking and placing the lid, ensuring the stability of repeated taking and placing of the lid, and enabling the next step of the pharmaceutical process to proceed smoothly.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Embodiment 1

[0041] In the present invention, the medicine residue extrusion device is used to extract the medicine liquid from the medicine residue in the medicine decoction pot 107. The medicine residue extrusion device mainly includes a medicine pressing frame 100, a cover structure 200, an extrusion structure 300 and a pressure head flushing structure 400.

[0042] The medicine pressing frame 100 is used to connect and fix the lid lifting structure 200, the squeezing structure 300 and the pressure head flushing structure 400. Moreover, the three functional structures can be reasonably arranged in space, and when the operation of lifting the pot lid 106 and squeezing the medicine residue is performed on the medicine decocting pot 107, they can be performed alternately in sequence without interfering with each other. At the same time, each time the squeezing structure 300 performs the operation of squeezing the medicine residue, the pressure head 307 in contact with the medicine residue can be cleaned in the pressure head flushing structure 400, so as to prevent the pressure head 307 from bringing the medicine liquid into different medicine decocting pots 107, affecting or even destroying the efficacy of the medicine liquid in the medicine decocting pot 107.

[0043] like Figure 1 As shown, x, y, and z are mutually perpendicular direction marks, and the medicine pressing frame 100 includes a cubic frame formed by connecting square tubes, and the length of the cubic frame in the x direction is greater than the diameter of the medicine decoction pot 107, so that the medicine decoction pot 107 can be stably placed in the medicine pressing frame 100. A bracket platform 108 for placing the pressure head flushing structure 400 is provided on the outer side surface of the cubic frame in the x direction, and the bracket platform 108 is higher than the bottom edge of the cubic frame in the z direction.

[0044] like Figure 2 As shown, the lid lift structure 200 includes a feeding assembly and a clamping assembly. The feeding assembly has a lid lift sliding block 205 that can move along the extending direction of the feeding assembly. The clamping assembly includes two pot lid clamping claws 213 that can move closer or farther away from the pot lid driven by a telescoping body 211.

[0045] The flip cover structure 200 further includes a first flip cover structure connection frame 206 having a cantilever end, which is fixedly connected to the flip cover sliding block 205. The cantilever end of the first flip cover structure connection frame 206 is connected to the telescopic device body 211, and the protruding direction of the cantilever end is the same as the extending direction of the feeding assembly. When the flip cover sliding block 205 moves to one end of the feeding assembly, the telescopic device body 211 exceeds the feeding assembly.

[0046] like Figure 2 As shown, the cover structure 200 includes a cover structure first connecting frame 206, a cover structure second connecting frame 207, a first lifter vertical connecting plate 208 and a first lifter 209. The feeding assembly is mainly composed of a first driving rod power input block 202, a cover guide rod 203, a first sliding block driving rod 204 and a cover sliding block 205.

[0047] The first connecting frame 206 of the flip cover structure is composed of a rectangular flat plate and an elongated rib plate. The size of the rectangular flat plate is consistent with the bottom surface of the flip cover sliding block 205, and the rectangular flat plate is fixedly connected to the flip cover sliding block 205. The elongated rib plate has a long side and a short side, and its shape is similar to a right-angled trapezoid. The elongated rib plate is perpendicular to the rectangular flat plate and fixed in the middle of the rectangular flat plate with the short side, and its long side exceeds the rectangular flat plate, similar to a cantilever end. The cantilever end is formed by the part of the long side of the elongated rib plate protruding from the short side, and the telescoping device body 211 is connected to the end on the long side and is separated from the feeding assembly by a certain distance.

[0048] The clamp assembly includes a telescope body 211, a telescope movable side plate 212 and a pot cover clamp 213. The telescope movable side plate 212 is movably connected to the telescope body 211, and the relative position of the telescope movable side plate 212 and the telescope body 211 can be changed by gas or liquid drive.

[0049] The lid-lifting structure 200 grabs the pot lid 106 of the medicine decoction pot 107 through two pot lid claws 213 that can be opened and closed, and also fixes the telescopic device body 211 used to drive the pot lid claws 213 to move on a feeding assembly, and the feeding assembly drives the telescopic device body 211 to move through a lid-lifting sliding block 205 that moves in a straight line. The movable distance of the lid-lifting sliding block 205 is greater than the diameter of the medicine decoction pot 107, which can ensure that the pot lid claws 213 completely move the pot lid 106 out of the pot mouth of the medicine decoction pot 107, so as to achieve the purpose of moving the pressure head in the extrusion structure 300 to the top of the medicine decoction pot 107 to smoothly extrude the medicine residue.

[0050] Embodiment 2

[0051] The structure is further optimized on the basis of the above embodiment. The first connecting frame 206 of the flip cover structure is fixedly connected to the flip cover sliding block 205 at the top with a rectangular flat plate, and is fixedly connected to the second connecting frame 207 of the flip cover structure at the bottom with the long side of the elongated rib plate. The second connecting frame 207 of the flip cover structure is a rectangular flat plate structure, and its middle part in the width direction is connected to the long side of the elongated rib plate and is perpendicular to the elongated rib plate.

[0052] The retractor body 211 is connected to the plane of the second connecting frame 207 of the long flip cover structure.

[0053] like Figure 1 As shown, the second connecting frame 207 of the flip cover structure and the portion of the elongated rib plate that exceeds the rectangular flat plate protrude toward the direction close to the medicine decoction pot 107. The length of the second connecting frame 207 of the flip cover structure is greater than the length of the long side of the elongated rib plate, and one end thereof that exceeds the elongated rib plate protrudes toward the cantilever end and is connected to the telescopic device body 211.

[0054] The second connecting frame 207 of the flip cover structure is protruded in the direction where the lengthened rib protrudes from the rectangular flat plate, which can extend the cantilever end formed by the first connecting frame 206 of the flip cover structure, so that the flip cover structure 200 can better avoid the extrusion structure by feeding in a straight direction.

[0055] Embodiment 3

[0056] The structure is further optimized on the basis of the above embodiment. A first lifter 209 is arranged at the end of the second connecting frame 207 of the flip cover structure. The first lifter 209 includes a fixed part and a movable part, and the movable part can move in a straight line direction in the fixed part and has two fixed positions. The fixed part of the first lifter 209 is connected to an end of the second connecting frame 207 of the flip cover structure that exceeds the lengthened rib plate. The first lifter 209 is fixedly connected to the second connecting frame 207 of the flip cover structure in a manner that the movable part moves in a vertical direction.

[0057] The movable part of the first lifter 209 is fixedly connected to the retractor body 211 , and can drive the retractor body 211 to move up and down in the vertical direction relative to the second connecting frame 207 of the flip cover structure.

[0058] The first lifter 209 ensures that the clamp assembly for grabbing the pot cover can be changed in height, so that when the feeding assembly drives the clamp assembly to move toward the medicine-decoction pot 107, the pot cover clamping claw 213 can move to the top of the medicine-decoction pot 107 at a height higher than the pot cover 106, and then drop from above to grab the pot cover, thereby avoiding the situation where the pot cover clamping claw 213 accidentally collides with the medicine-decoction pot 107 or the pot cover 106.

[0059] Embodiment 4

[0060] The structure is further optimized on the basis of the above embodiment. A first lifter vertical connecting plate 208 having the same width as the second connecting frame 207 of the flip cover structure is provided, and the first lifter vertical connecting plate 208 is connected to the second connecting frame 207 of the flip cover structure and the lengthened rib plate at the same time.

[0061] The first lifter vertical connecting plate 208 is vertically connected with the end of the cantilever end of the lengthened rib plate at its middle part in the width direction. Simultaneously, the flat surface of the first lifter vertical connecting plate 208 is also perpendicular to the flat surface of the second connecting frame 207 of the cover structure.

[0062] In the height direction, the first lifter vertical link plate 208 is spaced a certain distance from the feed assembly.

[0063] The fixing part of the first lifter 209 is connected to the first lifter vertical connecting plate 208, and its movable part passes through the through hole on the second connecting frame 207 of the flip cover structure and is connected to the telescopic device body 211. The first lifter 209 is connected to the first lifter vertical connecting plate 208 in a manner that the movable part moves in the vertical direction.

[0064] The first lifter 209 can be driven by gas or liquid.

[0065] By setting the first lifter vertical connecting plate 208 on the second connecting frame 207 of the flip cover structure and fixing the first lifter 209 on the first lifter vertical connecting plate 208, the stability of the first lifter 209 during movement is enhanced, and the vibration generated by the up and down movement of its movable parts to avoid destroying the connection relationship between the first lifter 209 and the second connecting frame 207.

[0066] Embodiment 5

[0067] The above embodiment is further optimized by adding a telescopic movable side plate 212 between the telescopic main body 211 and the pot cover clamping claw 213, and setting the telescopic movable side plate 212 and the telescopic main body 211 to be movably connected.

[0068] The clamping assembly consists of two telescopic movable side plates 212 movably connected to the telescopic main body 211 . The telescopic movable side plates 212 move along a horizontal straight line direction and are each connected to a pot cover clamping claw 213 .

[0069] For example, a horizontal cylindrical through hole is provided on the telescope body 211, a straight rod matching the through hole is provided on the plate surface of the telescope movable side plate 212, and the straight rod is inserted into the through hole so as to slide relative to the through hole.

[0070] In this way, the telescopic movable side plate 212 and the telescopic main body 211 form a component that can drive the pot cover claw 213 to move. By setting the telescopic movable side plate 212, the pot cover claw 213 is prevented from being directly connected to the telescopic main body 211, ensuring that the pot cover claw 213 can be assembled and disassembled more conveniently, which is conducive to adjustment and maintenance.

[0071] Embodiment 6

[0072] like Figure 2As shown, the structure is further optimized on the basis of the above embodiment. A telescopic device fixing plate 210 is also provided between the first lifter 209 and the telescopic device body 211. The telescopic device fixing plate 210 is a flat plate member, and its upper part is fixedly connected to the movable part of the first lifter 209. The telescopic device body 211 is connected to the lower part of the telescopic device fixing plate 210. The first lifter 209 drives the telescopic device fixing plate 210 to move up and down, and then the telescopic device body 211 moves with the telescopic device fixing plate 210. It is ensured that the pot cover claw 213 can fall from the top of the decoction pot 107.

[0073] The telescopic body 211 is movably connected to two telescopic movable side plates 212. The two telescopic movable side plates 212 can be driven by gas or liquid to change their relative positions with the telescopic body 211. Figure 1 As shown, the two retractor movable side plates 212 are distributed on both sides of the retractor body 211 along the x direction, and perform opening and closing actions along the x direction.

[0074] like Figure 2 As shown, the pot cover clamp 213 has two flat edges, which are perpendicular to each other. A mounting hole is provided on one flat edge for fixed connection with the telescopic movable side plate 212, and an arc-shaped notch is provided on the other flat edge, which is arranged in the middle of the edge of the flat edge. The two telescopic movable side plates 212 are distributed on opposite sides of the telescopic body 211, and the two pot cover clamps 213 are respectively connected to one telescopic movable side plate 212. The arc-shaped notches of the two pot cover clamps 213 are arranged facing each other, and the two arc-shaped notches are aligned.

[0075] The arc-shaped notch on the pot cover claw 213 ensures that when the two telescopic movable side plates 212 are closed, the handle of the pot cover 106 can be just stuck between the two pot cover claws 213 and avoids the pot cover claw 213 from squeezing out too much to damage the handle of the pot cover 106, which is convenient for carrying the pot cover 106.

[0076] Furthermore, the flat edge with the arc-shaped notch in the pot cover clamping claw 213 is arranged just below the telescopic device body 211, and by adjusting the length of the flat edge with the mounting hole in the pot cover clamping claw 213, a certain distance can be ensured between the flat edge with the arc-shaped notch and the telescopic device body 211. A height sufficient to accommodate the pot cover handle can also be reserved to avoid contact or collision between the pot cover handle and the telescopic device body, thereby ensuring the stability and reliability of the lid lifting structure 200.

[0077] Embodiment 7

[0078] like Figure 2As shown, the structure is further optimized based on the above embodiment. The cover lift structure 200 includes a first drive rod power input block 202, a cover lift guide rod 203, a first slide block drive rod 204 and a cover lift slide block 205.

[0079] The cover-lifting guide rod 203 is arranged parallel to the first slide block driving rod 204, and the two cover-lifting guide rods 203 are symmetrically distributed on both sides of the first slide block driving rod 204. The cover-lifting slide block 205 is provided with three fitting holes, and is fittedly connected with the cover-lifting guide rod 203 and the first slide block driving rod 204, so as to form a feeding assembly that can slide along the length direction of the cover-lifting guide rod 203.

[0080] The cover-lifting sliding block 205 is pushed by the first sliding block driving rod 204 and can reciprocate on the first sliding block driving rod 204 along the central axis direction of the first sliding block driving rod 204. The cover-lifting sliding block 205 is sleeved on the first sliding block driving rod 204. The cross section of the cover-lifting sliding block 205 is rectangular, and three sleeve holes are provided on it, wherein the sleeve hole at the center is larger and the sleeve holes at both sides are smaller.

[0081] The first sliding block driving rod 204 is in the shape of a long straight cylinder, and can drive the cover-lifting sliding block 205 by means of threaded contact. An external thread is arranged on the outer surface of the first sliding block driving rod 204, and a hole with an internal thread is arranged on the cover-lifting sliding block 205. The first sliding block driving rod 204 is inserted into the threaded hole of the cover-lifting sliding block 205. By rotating the first sliding block driving rod 204, the cover-lifting sliding block 205 can be driven to move along the central axis direction of the first sliding block driving rod 204 through the matching internal and external threads.

[0082] The first sliding block driving rod 204 can also drive the cover sliding block 205 by magnetic attraction. The cover sliding block 205 is sleeved on the first sliding block driving rod 204. The interior of the first sliding block driving rod 204 is hollowed out to form a through hole, so that its outer surface and the surface of the through hole are both set to smooth cylindrical surfaces and are concentric. A cylindrical magnet is installed in the through hole, so that the cross section of the magnet fills the cross section of the through hole, and the length of the magnet is at most the same as the length of the sleeve hole on the cover sliding block 205.

[0083] The first sliding block driving rod 204 is made of non-magnetic material, such as aluminum, and the cover sliding block 205 is made of magnetic material, so that the magnet can pass through the first sliding block driving rod 204 to attract the cover sliding block 205, thereby driving the cover sliding block 205 to move by pushing the magnet.

[0084] In the feeding assembly, the first driving rod power input block 202 is a component for providing power to the first sliding block driving rod 204 .

[0085] The first sliding block driving rod 204 can be driven by a motor, thereby driving the cover sliding block 205 to move. The first sliding block driving rod 204 is fixed to the first driving rod power input block 202 by a rotational connection, and the end of the first sliding block driving rod 204 is fitted with the inner ring of the rolling bearing, and the outer ring of the rolling bearing is fitted in the first driving rod power input block 202. Then, the output end of the motor is connected to the first driving rod power input block 202, and the motor directly drives the first sliding block driving rod 204 to rotate.

[0086] The first sliding block driving rod 204 can also be driven by gas or liquid, thereby driving the cover sliding block 205 to move. A mounting hole for fixedly connecting the first sliding block driving rod 204 and the cover guide rod 203 is provided on one end face of the first driving rod power input block 202. An inlet for introducing gas or liquid is provided on the other end face of the first driving rod power input block 202, and then the inlet is connected to the mounting hole connected to the first sliding block driving rod 204. When gas or liquid is poured into the inlet, the magnet installed in the first sliding block driving rod 204 can be pushed by the gas or liquid, so that the magnet can reciprocate in the through hole of the first sliding block driving rod 204.

[0087] The cover-lifting guide rod 203 is made of a slender straight rod with a smooth outer surface, and the cross section of the straight rod can be circular or polygonal. The cover-lifting guide rod 203 can be made of a solid straight rod or a hollow straight rod.

[0088] The first drive rod power input block 202, the lid-lifting guide rod 203, the first sliding block drive rod 204 and the lid-lifting sliding block 205 constitute a feeding assembly of the lid-lifting structure 200, which is used to drag the pot cover claw 213 to move linearly along the y direction, so that it moves to the top of the medicine pot lid 106, or moves it from the position of the medicine pot 107 to the standby position to avoid opening the pot mouth of the medicine pot 107.

[0089] The cover-lifting guide rod 203 and the first sliding block driving rod 204 are arranged in parallel, and the two cover-lifting guide rods 203 are symmetrically distributed on both sides of the first sliding block driving rod 204. Their ends are fixedly connected in the length direction by the first driving rod power input block 202. The cover-lifting structure fixing seat 201 is also connected to the first driving rod power input block 202, which is used to fix the cover-lifting structure 200 on the medicine pressing frame 100. Figure 1 As shown, the flip cover structure 200 is connected to the first connecting rod 101 of the medicine pressing frame and the third connecting rod 103 of the medicine pressing frame respectively through the flip cover structure fixing seat 201, so that the horizontal feeding movement in the flip cover structure 200 is along the y direction.

[0090] The lid-lifting structure 200 realizes the purpose of using the lid claws 213 to completely remove the lid 106 from the decoction pot 107 and clear the pot mouth, thereby replacing manual labor, solving the problem of manual fatigue and error-proneness due to repetitive labor, improving the speed of taking and placing the lid 106, ensuring the stability of repeated taking and placing of the lid 106, and ensuring that the next step of the pharmaceutical process can proceed smoothly.

[0092] In the present invention, the medicine residue extrusion device is used to extract the medicine liquid from the medicine residue in the medicine decoction pot 107. The medicine residue extrusion device mainly includes a medicine pressing frame 100, a cover structure 200, an extrusion structure 300 and a pressure head flushing structure 400.

[0093] The medicine pressing frame 100 is used to connect and fix the lid lifting structure 200, the squeezing structure 300 and the pressure head flushing structure 400. Moreover, the three functional structures can be reasonably arranged in space, and when the operation of lifting the pot lid 106 and squeezing the medicine residue is performed on the medicine decocting pot 107, they can be performed alternately in sequence without interfering with each other. At the same time, each time the squeezing structure 300 performs the operation of squeezing the medicine residue, the pressure head 307 in contact with the medicine residue can be cleaned in the pressure head flushing structure 400, so as to prevent the pressure head 307 from bringing the medicine liquid into different medicine decocting pots 107, affecting or even destroying the efficacy of the medicine liquid in the medicine decocting pot 107.

[0100] In the two vertical sides of the cubic frame perpendicular to the x direction, the second connecting rod 102 of the medicine pressing frame is connected to the vertical side of the left side and is distributed along the y direction. One end of the third connecting rod 103 of the medicine pressing frame is connected to the middle of the second connecting rod 102 of the medicine pressing frame and is parallel to the first connecting rod 101 of the medicine pressing frame. The interval between the third connecting rod 103 of the medicine pressing frame and the first connecting rod 101 of the medicine pressing frame is equal to the length of the flip cover structure 200.

[0101] The first connecting rod 101 , the second connecting rod 102 and the third connecting rod 103 of the medicine pressing frame are at the same height in the cubic frame, and the fourth connecting rod 104 of the medicine pressing frame is lower than the first connecting rod 101 of the medicine pressing frame and is connected in the cubic frame.

[0103] The medicinal residue extrusion device is further optimized on the basis of the above embodiment, so that the extrusion structure 300 includes a second driving rod power input block 301 , an extrusion head sliding block 302 , an extrusion horizontal guide rod 303 and a second sliding block driving rod 304 .

[0104] The extrusion head sliding block 302 is pushed by the second sliding block driving rod 304 and can reciprocate on the second sliding block driving rod 304 along the central axis direction of the second sliding block driving rod 304. The extrusion head sliding block 302 is sleeved on the second sliding block driving rod 304. The cross section of the extrusion head sliding block 302 is rectangular, and three sleeve holes are provided thereon, wherein the sleeve hole at the center is larger and the sleeve holes at both sides are smaller.

[0105] The second sliding block driving rod 304 is in the shape of a long straight cylinder, and can drive the extrusion head sliding block 302 by means of threaded contact. An external thread is arranged on the outer surface of the second sliding block driving rod 304, and a hole with an internal thread is arranged on the extrusion head sliding block 302. The second sliding block driving rod 304 is inserted into the threaded hole of the extrusion head sliding block 302. By rotating the second sliding block driving rod 304, the extrusion head sliding block 302 can be driven to move along the central axis direction of the second sliding block driving rod 304 through the matching internal and external threads.

[0106] The second sliding block driving rod 304 can also drive the extrusion head sliding block 302 by magnetic attraction. The extrusion head sliding block 302 is sleeved on the second sliding block driving rod 304. The interior of the second sliding block driving rod 304 is hollowed out to form a through hole, so that its outer surface and the surface of the through hole are both set to smooth cylindrical surfaces and are concentric. A cylindrical magnet is installed in the through hole so that the cross section of the magnet fills the cross section of the through hole, and the length of the magnet is at most the same as the length of the sleeve hole on the extrusion head sliding block 302.

[0107] The second sliding block driving rod 304 is made of non-magnetic material, such as aluminum. The extrusion head sliding block 302 is made of magnetic material, so that the magnet can attract the extrusion head sliding block 302 through the second sliding block driving rod 304, thereby driving the extrusion head sliding block 302 to move by pushing the magnet.

[0108] The second driving rod power input block 301 is a component for providing power to the second sliding block driving rod 304 .

[0109] The second sliding block driving rod 304 can be driven by a motor, thereby driving the extrusion head sliding block 302 to move.

Then, the output end of the motor is connected to the second driving rod power input block 301, and the motor directly drives the second sliding block driving rod 304 to rotate.

[0110] The second sliding block driving rod 304 can also be driven by gas or liquid, thereby driving the extrusion head sliding block 302 to move. A mounting hole for fixedly connecting the second sliding block driving rod 304 and the extrusion horizontal guide rod 303 is provided on one end face of the second driving rod power input block 301. An inlet for introducing gas or liquid is provided on the other end face of the second driving rod power input block 301, and then the inlet is connected to the mounting hole connected to the second sliding block driving rod 304. When gas or liquid is poured into the inlet, the magnet installed in the second sliding block driving rod 304 can be pushed by the gas or liquid, so that the magnet can reciprocate in the through hole of the second sliding block driving rod 304.

[0111] The guide rod of the extrusion head 307 is made of a slender straight rod with a smooth outer surface, and the cross section of the straight rod can be circular or polygonal. The extrusion horizontal guide rod 303 can be made of a solid straight rod or a hollow straight rod.

[0112] The second driving rod power input block 301, the extrusion horizontal guide rod 303, the second sliding block driving rod 304 and the extrusion head sliding block 302 constitute the feeding assembly of the extrusion structure 300, which is used to drag the pressure head 307 to move in a straight line along the x direction, so that it moves to the top of the decoction pot 107, or moves it from the position of the decoction pot 107 to the standby position to avoid opening the pot mouth of the decoction pot 107.

[0113] The extrusion horizontal guide rod 303 and the second sliding block driving rod 304 are arranged in parallel, and the two extrusion horizontal guide rods 303 are symmetrically distributed on both sides of the second sliding block driving rod 304. Their ends are fixedly connected in the length direction by the second driving rod power input block 301. The second driving rod power input block 301 is also connected to an extrusion structure fixing seat for fixing the extrusion structure 300 on the medicine pressing frame 100. Figure 1 As shown, the feeding assembly of the extrusion structure 300 is connected to the vertical side of the fourth connecting rod 104 of the medicine pressing frame through the extrusion structure fixing seat, so that the horizontal feeding movement in the extrusion structure 300 is along the x direction.

[0114] The extrusion structure 300 further includes an extrusion head first connecting frame 305 , a second lifter 306 , a pressing head 307 , an extrusion vertical guide rod 308 , a guide rod sliding sleeve 309 and an extrusion head second connecting frame 310 .

The fixed part of the second lifter 306 is fixed above the flange plate, and its movable part can extend or retract downward along the y direction.

[0117] The pressure head 307 is a circular flat plate with a connection block at the center. The pressure head 307 is connected to the movable part of the second lifter 306. Driven by the second lifter 306, the pressure head 307 can be lifted and lowered in the y direction, so as to squeeze the medicinal materials in the decoction pot 107. In order to prevent the pressure head 307 from rotating relative to the second lifter 306 and causing the connection between the pressure head 307 and the movable part to loosen, a guide rod sleeve 309 is provided on both sides of the second lifter 306.

[0118] Two connecting blocks are symmetrically arranged on the same surface of the connecting block at the center of the pressing head 307. Two extrusion vertical guide rods 308 pass through the guide rod sliding sleeve 309 on the first connecting frame 305 of the extrusion head and are connected to the pressing head 307, thereby enhancing the stability of the pressing head 307 when extruding the medicinal residue.

[0119] In order to enhance the strength of the first connecting frame 305 of the extrusion head and prevent the reaction force of the second lifter 306 from damaging the first connecting frame 305 of the extrusion head when extruding the medicinal residue, a second connecting frame 310 of the extrusion head is further provided on the top of the first connecting frame 305 of the extrusion head.

The second connecting frame 310 of the extrusion head supports the first connecting frame 305 of the extrusion head through the linear slider 311 and the linear slide rail 312 fixed to the bottom surface of the third connecting rod 103 of the medicine pressing frame. When the feeding assembly of the extrusion structure 300 drives the second lifter 306 to move along the x direction, the second connecting frame 310 of the extrusion head can follow unhindered and provide support force for the second lifter 306.
