Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0029] As Figures 1 - 9 shown, a pressing and extraction device for traditional Chinese medicine pharmaceutical use proposed in an embodiment of the present application includes:

[0030] Frame 1, on which a pressing box 2, a feeding box 3 and a feeding channel 4 are arranged. The feeding box 3 and the feeding channel 4 are both fixedly arranged on the frame 1. A filtering tank 5 is arranged in the pressing box 2. The filtering tank 5 is located at the inner bottom of the pressing box 2. A filtering member is arranged in the filtering tank 5, and the filtering member is used for solid-liquid separation of the pressed traditional Chinese medicine materials. The residue of the medicinal residues remains in the pressing box 2, and the medicinal liquid enters the filtering tank 5. An outlet pipe 6 is arranged on the pressing box 2. One end of the outlet pipe 6 is communicated with the filtering tank 5, and the other end is connected with a liquid storage device (not shown in the accompanying drawings of the specification). The liquid storage device stores the medicinal liquid. The feeding box 3 is constructed with a feeding port 7 and a discharging port 8. One end of the feeding channel 4 corresponds to the pressing box 2, and the other end is communicated with the discharging port 8. A plurality of trapezoidal blocks 9 are arranged in the feeding box 3. The trapezoidal blocks 9 are arranged vertically and fixedly arranged in the feeding box 3. The plurality of trapezoidal blocks 9 are arranged in a horizontal array and the lengths increase sequentially from bottom to top. A plurality of wedge-shaped plates 10 which are the same in number as and correspond to the trapezoidal blocks 9 one by one are slidably arranged in the feeding box 3. The wedge-shaped plates 10 are arranged vertically and slide along the vertical direction. The plurality of wedge-shaped plates 10 are arranged in a horizontal array and the lengths increase sequentially from bottom to top. In this embodiment, the number of the trapezoidal blocks 9 and the wedge-shaped plates 10 is the same and both are three. A driving member is arranged on the frame 1 and the feeding box 3, and it is used to drive the plurality of wedge-shaped plates 10 to slide synchronously and reciprocally. A pressing hammer 11 is slidably arranged on the frame 1. The pressing hammer 11 slides along the vertical direction. A driving part which acts on the pressing hammer 11 and drives it to slide reciprocally is arranged on the frame 1;

[0031] In the initial state, the pressing hammer 11 is in the initial position, and the three wedge-shaped plates 10 are all in the initial position. The longest wedge-shaped plate 10 corresponds to the discharging port 8, the middle wedge-shaped plate 10 corresponds to the longest trapezoidal block 9, and the shortest wedge-shaped plate 10 corresponds to the middle trapezoidal block 9. When in use, connect the other end of the outlet pipe 6 with the liquid storage device, put the traditional Chinese medicine materials into the feeding box 3 through the feeding port 7, and drive the three wedge-shaped plates 10 to slide synchronously and reciprocally through the driving member. The three wedge-shaped plates 10 first slide down to the limit position and respectively correspond to the three trapezoidal blocks 9, and then slide up to the initial position, and so on. Through the cooperation of the three wedge-shaped plates 10 and the three trapezoidal blocks 9, the traditional Chinese medicine materials are lifted step by step from bottom to top, and finally the traditional Chinese medicine materials are transported to the discharging port 8. Then the traditional Chinese medicine materials enter the feeding channel 4 from the discharging port 8 and fall into the pressing box 2 to realize automatic, continuous and intermittent feeding of the traditional Chinese medicine materials into the pressing box 2. At the same time, drive the pressing hammer 11 to slide reciprocally through the driving part. The pressing hammer 11 first slides down and presses the traditional Chinese medicine materials in the pressing box 2, and then the pressing hammer 11 slides up to the initial position, and so on, to realize repeated pressing of the traditional Chinese medicine materials. The pressed traditional Chinese medicine materials are subjected to solid-liquid separation through the filtering member. The residue of the medicinal residues remains in the pressing box 2, and the medicinal liquid enters the filtering tank 5 and enters the liquid storage device through the outlet pipe 6;

[0032] In summary, when the present application is in use, it can automatically and continuously add traditional Chinese medicine materials into the pressing box 2 intermittently, eliminating the need for staff to frequently add traditional Chinese medicine materials manually. This is convenient to operate, reduces the workload of the staff, and improves work efficiency. Therefore, it is more practical.

[0033] As Figures 8 - 9 shown, in some embodiments, the driving member includes a reciprocating lead screw 12 rotatably provided on the frame 1. The reciprocating lead screw 12 is in the vertical direction. A sliding frame 13 meshing with the reciprocating lead screw 12 is slidably provided on the feeding box 3. The sliding frame 13 slides in the vertical direction, and a plurality of wedge-shaped plates 10 are all connected to the sliding frame 13; a plurality of wedge-shaped plates 10 are all fixedly connected to the sliding frame 13.

[0034] Referring to the above, in the initial state, the sliding frame 13 is at the initial position, and a plurality of wedge-shaped plates 10 are all at the initial position. When in use, the reciprocating lead screw 12 is driven to rotate, and the sliding frame 13 reciprocates in the vertical direction due to the meshing action. When the sliding frame 13 slides down to the limit position, it drives a plurality of wedge-shaped plates 10 to slide down to the limit position together. On the contrary, when the sliding frame 13 slides up to the initial position, it drives a plurality of wedge-shaped plates 10 to slide up to the initial position together, so as to drive a plurality of wedge-shaped plates 10 to reciprocate synchronously.

[0035] As Figures 2 - 6 shown, in some embodiments, a plurality of moving wheels 14 are rotatably provided at the bottom of the pressing box 2. The plurality of moving wheels 14 are all in the vertical direction and are distributed in a rectangular array. A plurality of positioning blocks 15 that are all in contact and overlap with the pressing box 2 are provided on the frame 1. The positioning blocks 15 are fixedly provided on the frame 1. A positioning rod 16 is provided on the positioning block 15. The positioning rod 16 is in the horizontal direction and is fixedly provided on the positioning block 15. The pressing box 2 is provided with positioning holes 17 that are the same in number as and correspond to the positioning rods 16 one by one. The positioning holes 17 are opened in the horizontal direction. The positioning rod 16 is inserted and matched with the positioning hole 17. A locking nut 18 that is in contact and overlaps with the pressing box 2 is threadedly provided on the positioning rod 16. A threaded section is formed on the positioning rod 16, and the locking nut 18 is threadedly matched with the threaded section.

[0036] Referring to the above, in the initial state, the pressing box 2 is in a disassembled state. Before use, the pressing box 2 needs to be installed. The specific operation is as follows: move the pressing box 2 together through multiple moving wheels 14, so that multiple positioning rods 16 respectively correspond to and are inserted into multiple positioning holes 17 until the pressing box 2 abuts and overlaps with multiple positioning blocks 15. Then, tighten multiple locking nuts 18 onto multiple positioning rods 16 respectively until multiple locking nuts 18 all abut and overlap with the pressing box 2 and the pressing box 2 cannot move, so as to achieve installation. On the contrary, after use, disconnect the other end of the liquid outlet pipe 6 from the liquid storage device, and then disassemble the pressing box 2 to facilitate pouring out the medicinal residues in the pressing box 2. The specific operation is as follows: loosen multiple locking nuts 18 respectively until they are disengaged from multiple positioning rods 16, move the pressing box 2 together through multiple moving wheels 14, so that multiple positioning rods 16 respectively withdraw from multiple positioning holes 17, and the pressing box 2 moves away from multiple positioning blocks 15, so as to achieve disassembly.

[0037] As Figure 4 shown, in some embodiments, the filter element includes a first filter screen 19 and a second filter screen 20 which are both slidably arranged in the filter groove 5 and are distributed at intervals up and down. The first filter screen 19 and the second filter screen 20 are both in a horizontal direction and both slide in the vertical direction. The first filter screen 19 is fixedly connected to the pressing box 2 through multiple bolts;

[0038] Referring to the above, in the initial state, both the first filter screen 19 and the second filter screen 20 are located in the filter groove 5 and are distributed at intervals up and down. The first filter screen 19 is fixedly connected to the pressing box 2 through multiple bolts. During use, through the cooperative action of the first filter screen 19 and the second filter screen 20, the liquid medicine is double-filtered to improve the filtering effect. After pouring out the medicinal residues in the pressing box 2, disconnect the connection and fixation between the first filter screen 19 and the pressing box 2, so that both the first filter screen 19 and the second filter screen 20 slide out of the filter groove 5 to facilitate cleaning of the first filter screen 19 and the second filter screen 20.

[0039] As Figure 2 shown, in some embodiments, two protective covers 21 that can be enclosed into a U-shaped structure are detachably arranged on the top of the pressing box 2 through bolts. The protective covers 21 are in a vertical direction, and the free ends of the protective covers 21 are constructed in a tapered shape that contracts inward;

[0040] Referring to the above, after the pressing box 2 is installed, install two protective covers 21 on the top of the pressing box 2 through bolts respectively, and the two protective covers 21 are enclosed into a U-shaped structure. When the pressing hammer 11 repeatedly presses the Chinese herbal medicine materials, the U-shaped structure can protect the Chinese herbal medicine materials to prevent them from splashing. Through the tapered setting that contracts inward, the protective effect can be further improved. On the contrary, when the pressing box 2 is disassembled, first disassemble the two protective covers 21 from the top of the pressing box 2.

[0041] As Figures 9 - 11 shown, in some embodiments, the driving part includes a driving disk 22 rotatably arranged on the frame 1. The driving disk 22 is in the vertical direction. A slider 23 is slidably arranged on the driving disk 22. The sliding direction of the slider 23 is perpendicular to the axis of the driving disk 22. A screw rod 24 with a thread passing through the slider 23 is rotatably arranged on the driving disk 22. The screw rod 24 is perpendicular to the axis of the driving disk 22. A turntable 25 is arranged on the slider 23. The turntable 25 is in the vertical direction and is fixedly arranged on the slider 23. A circumferential groove 26 is formed in the turntable 25. The circumferential groove 26 is coaxially distributed with the turntable 25. A convex block 27 slidably engaged with the circumferential groove 26 is arranged at the free end of the pressing hammer 11. The convex block 27 is in the horizontal direction and is fixedly arranged at the top end of the pressing hammer 11;

[0042] Referring to the above, in the initial state, the slider 23 is located at the initial position and close to the axis of the driving disk 22. At this time, the eccentricity between the turntable 25 and the driving disk 22 is small, that is, the sliding stroke of the pressing hammer 11 is small. During use, the screw rod 24 is driven to rotate forward. The slider 23 slides to the limit position due to the thread action, driving the turntable 25 to move together. The eccentricity between the turntable 25 and the driving disk 22 increases, that is, the sliding stroke of the pressing hammer 11 increases. As the Chinese herbal medicine materials in the pressing box 2 increase, the sliding stroke of the pressing hammer 11 should become smaller and smaller. By driving the screw rod 24 to rotate reversely, the slider 23 slides to the initial position due to the thread action, driving the turntable 25 to move together. The eccentricity between the turntable 25 and the driving disk 22 decreases, that is, the sliding stroke of the pressing hammer 11 decreases. By driving the driving disk 22 to rotate, the screw rod 24, the slider 23 and the turntable 25 are driven to rotate together. Since the turntable 25 and the driving disk 22 are eccentrically distributed, the convex block 27 will slide reciprocally in the circumferential groove 26, thereby driving the pressing hammer 11 to slide reciprocally.

[0043] As Figures 9 - 10 shown, in some embodiments, the driving disk 22 is linked with the reciprocating lead screw 12 through a linkage member. When the driving disk 22 rotates, the reciprocating lead screw 12 is driven to rotate through the linkage member;

[0044] Referring to the above, when the driving disk 22 rotates, the reciprocating lead screw 12 is driven to rotate through the linkage member to realize the synchronous operation of the driving part and the driving member, improve the use synchronism, and at the same time, the operation is more convenient.

[0045] As Figures 9 - 10As shown, in some embodiments, the linkage member includes a linkage rod 28 rotatably arranged on the frame 1, the linkage rod 28 is in a vertical direction, the driving disc 22 and the linkage rod 28 are connected by a bevel gear assembly 29, the bevel gear assembly 29 includes two meshing bevel gears, the two bevel gears are respectively fixed on the driving disc 22 and the linkage rod 28, the linkage rod 28 and the reciprocating screw rod 12 are connected by a pulley assembly 30, the pulley assembly 30 includes two pulleys and a connecting belt, the two pulleys are respectively fixed on the linkage rod 28 and the reciprocating screw rod 12, and the connecting belt is wound around the two pulleys;

[0046] Referring to the above, when the driving disc 22 rotates, the linkage rod 28 is driven to rotate together through the bevel gear assembly 29. When the linkage rod 28 rotates, the reciprocating screw 12 is driven to rotate together through the pulley assembly 30 to realize the linkage between the driving disc 22 and the reciprocating screw 12.

[0047] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
