DETAILED DESCRIPTION

[0024] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings:

[0025] As attached Figure 1 -Attached Figure 5As shown, the present invention is a Chinese herbal medicine squeezing and extraction device, comprising a squeezing tank 1, a top cover 2 is buckled on the opening portion of the upper end of the squeezing tank 1, a liquid outlet component 3 is arranged at the lower end of the squeezing tank 1, a telescopic cylinder 4 is arranged on the top cover 2, the telescopic cylinder 4 is connected to the upper end of a moving rod 5 that movably passes through the top cover 2, a squeezing component 6 is arranged at the lower end of the moving rod 5, and the lower surface of the squeezing component 6 is a trapezoidal structure, a partition 7 is arranged below the squeezing component 6 in the squeezing tank 3, the upper surface of the partition 7 is a trapezoidal structure, and a through groove penetrating the partition 7 is arranged on the partition 7 8, a second filter screen 9, a first sealing plate 10, and a second sealing plate 11 are sequentially arranged in the through groove 8 from top to bottom, a plurality of protruding sealing columns 12 are arranged on the upper surface of the second sealing plate 11, a slot 13 corresponding to the number and position of the sealing columns 12 is arranged on the first sealing plate 10, a plurality of leakage holes 14 penetrating the second sealing plate 11 are arranged on the second sealing plate 11, a strip groove 15 penetrating the squeezing tank 3 is arranged on the side wall of the squeezing tank 3, the strip groove 15 is arranged vertically, and a connecting rod 16 on the side of the second sealing plate 11 passes through the strip groove 15 and extends to the outside of the squeezing tank 3. The above structure, when squeezing and extracting Chinese herbal medicines, is to squeeze the raw materials of Chinese herbal medicines, so that the medicinal liquid and the residue (dregs) in the raw materials are separated, the medicinal liquid is collected by the collecting component after flowing out, and the residue is filtered and isolated. When it is necessary to squeeze the Chinese herbal medicine, the operator opens the top cover 2, adds the Chinese herbal medicine to be squeezed into the squeezing tank through the opening, and the raw Chinese herbal medicine falls onto the partition 7, and then closes the top cover 2. The top cover 2 is fixedly connected to the squeezing tank 1 by bolts, and then the telescopic cylinder 4 is controlled to be extended and retracted by the control component, and the telescopic cylinder 4 drives the moving rod 5 to move up and down, and the moving rod 5 drives the squeezing component 6 (trapezoidal plate) to move back and forth up and down to squeeze the Chinese herbal medicine in the squeezing tank 1. The lower surface of the squeezing component 6 and the upper surface of the partition 7 are matched in shape, and the movable squeezing component 6 can reliably apply force on the fixed partition 7 to crush and squeeze the Chinese herbal medicine, so that the Chinese herbal medicine is separated into liquid medicine and residue. After the squeezing is completed, push the connecting rod 5 downward (this can be achieved by pushing the paddle downward), and the connecting rod 16 drives the second sealing plate 11 to move downward. At this time, the sealing column 12 (arc-shaped sealing column) on the second sealing plate 11 leaves the corresponding slot 13 (arc-shaped slot) on the first sealing plate 10, and the squeezed medicinal liquid flows through a plurality of arc-shaped slots into the through slot 8, and finally leaks to the bottom of the squeezing tank 1 through a plurality of leakage holes 15 on the second sealing plate 11. The residue will remain above the second filter screen 9, and a small amount of leaked residue will also be intercepted by the first filter screen 25 on the filter plate 23 of the filter component 21 located at the bottom of the squeezing tank 1. The final medicinal liquid will flow out through the liquid outlet component 3 at the bottom of the squeezing tank 1 and flow to the collecting component to collect the medicinal liquid. In this way, the squeezing and extraction of Chinese herbal medicines can be completed simply, efficiently, and with high quality. The medicinal liquid contains less residue and high quality, and does not require post-processing, which simplifies the process and improves processing efficiency.The Chinese herbal medicine squeezing and extraction device described in the present invention has a simple structure and can conveniently and efficiently squeeze and extract Chinese herbal medicines. It not only realizes the automation of squeezing, improves the squeezing efficiency, and reduces the labor intensity of squeezing, but also realizes the clean separation of residue and medicinal liquid during squeezing, thereby improving the efficiency and quality of medicinal liquid extraction.

[0026] The second sealing plate 11 of the Chinese herbal medicine squeezing and extraction device is movably arranged in the through groove 8, and a sliding cavity 17 is also arranged on the lower surface of the partition 4. The sliding cavity 17 is connected to the through groove 8 through a connecting channel 30. A spring 18 and a sliding rod 19 are arranged in sequence in the sliding cavity 17, and the sliding rod 19 is fixedly connected to the side of the second sealing plate 11 through a fixing rod 20. In the above structure, the through groove is a vertically arranged structure, which is used for the flow of the medicinal liquid after the medicinal liquid is squeezed. The second filter screen is mounted on the upper part of the through groove. In this way, on the one hand, it does not affect the normal filtration during squeezing. On the other hand, after one squeezing is completed, it is convenient to remove the second filter screen to clean the residue on the second filter screen, which is convenient for the next operation. The spring 18 and the sliding rod 19 are arranged in sequence in the sliding cavity 17, so that the spring applies pressure to the second sealing plate, so that the sealing column is mounted in the corresponding slot, and the through groove is disconnected. When no force is applied to the connecting rod, the squeezed medicine liquid will not flow down from the through groove. Instead, a downward force must be applied to the connecting rod to overcome the tension of the spring, drive the second sealing plate downward, and the sealing column leaves the slot of the first sealing plate. At this time, the residue is isolated, and the medicine liquid quickly leaks out from the slot and then through the leakage hole 15.

[0027] A filter component 21 is arranged below the partition 7 in the pressing tank 3 of the Chinese herbal medicine pressing and extraction device. The filter component 21 includes a positioning sleeve 22, a filter plate 23, and a transverse groove 24. The transverse groove 24 is arranged on the side wall of the pressing tank 3. A first filter screen 25 is arranged on the filter plate 23. One end of the filter plate 23 is clamped in the positioning sleeve 22, and a pull ring 26 at the other end of the filter plate 23 passes through the transverse groove 24 and extends to the outside of the pressing tank 3. With the above structure, after the liquid medicine passes through the first filter screen, some residues will remain in the liquid medicine. The second filter screen is used to perform secondary filtration on the liquid medicine to improve the filtration quality.

In the above structure, during the squeezing process, due to the action of the spring, the second sealing plate receives an upward force, so that the sealing column is located in the corresponding slot to achieve closure, so that during the squeezing process, no liquid medicine will flow down from the through slot. Instead, it is necessary to apply a downward external force on the connecting rod after the squeezing is completed to achieve the flow of the liquid medicine. When setting the slide cavity, two can also be set to apply force from different positions to improve stability.

[0029] The connecting rod 16 of the Chinese herbal medicine squeezing and extraction device extends to one end outside the squeezing tank 3, and a paddle plate 27 is fixedly provided. The connecting rod 16 is configured to be able to slide up and down in the strip groove 15. When a downward external force is applied to drive the paddle plate 27 to move downward, the paddle plate 27 is configured to be able to apply a downward force on the connecting rod 16, thereby driving the second sealing plate 11 to move downward through the connecting rod 16. When the connecting rod 16 drives the second sealing plate 11 to move downward, the sealing column 12 on the second sealing plate 11 is configured to be able to withdraw from the slot 14 on the first sealing plate 10. In the above structure, the paddle plate is used to drive the connecting rod to move up and down. The paddle plate applies a downward force to the connecting rod, and the sealing column leaves the slot. After the applied force disappears, the sealing column re-enters the slot.

[0030] The telescopic cylinder 4 of the Chinese herbal medicine squeezing and extraction device is connected to a control component 32 capable of controlling the telescopic cylinder 4 to be extended and retracted. When the control component 32 controls the telescopic cylinder 4 to be extended and retracted, the telescopic cylinder 3 is configured to be able to drive the lower surface of the squeezing component 6 and the upper surface of the partition 7 to continuously approach and move away through the motion rod 5, thereby squeezing the Chinese herbal medicine between the lower surface of the squeezing component 6 and the upper surface of the partition 7. The above structure drives the telescopic cylinder to reciprocate and retract through the control component, thereby driving the motion rod to drive the squeezing component to reciprocate and move up and down to achieve squeezing.

[0031] The second filter screen 9 in the through groove 8 on the partition 7 of the Chinese herbal medicine squeezing and extraction device is connected to the inner wall of the through groove 8 by clamping, the first sealing plate 10 is fixedly connected to the inner wall of the through groove 8 or clamped on the limiting boss in the through groove, and the second filter screen is movably clamped in the through groove. In the above structure, the second filter screen is movably clamped, which can be conveniently removed to clean the residue or replaced, and the first sealing plate is fixedly connected or clamped on the boss in the through groove, so that the first sealing plate can also be replaced. The second sealing plate is movably clamped, so that the second sealing plate can be controlled to move downward through the connecting rod.

[0032] The liquid outlet component 3 includes a liquid outlet pipe 28 and a valve 29. The liquid outlet pipe 28 runs through the lower end of the squeeze tank 3, and a valve 29 is provided at one end of the liquid outlet pipe 28 extending to the outside of the squeeze tank 3. In the above structure, the liquid storage tank is used to discharge liquid, and the valve is used to realize the on-off control of the liquid storage tank.

[0033] The inner bottom surface of the squeezing tank 3 is designed to be an arc-shaped structure convex downward.

[0034] A plurality of supporting legs 31 are fixedly provided at the lower end of the squeezing tank 3 .

[0035] The Chinese herbal medicine squeezing and extraction device of the present invention squeezes the Chinese herbal medicine raw materials when squeezing and extracting the Chinese herbal medicine, so that the medicinal liquid and the residue (dregs) in the raw materials are separated, and the medicinal liquid is collected by the collecting component after flowing out, and the residue is filtered and isolated. When it is necessary to squeeze the Chinese herbal medicine, the operator opens the top cover and adds the Chinese herbal medicine to be squeezed into the squeezing tank through the opening. The Chinese herbal medicine raw materials fall onto the partition, and then the top cover is closed. The top cover and the squeezing tank are fixedly connected by bolts. Then the telescopic cylinder is controlled to be retracted by the control component, and the telescopic cylinder drives the moving rod to move up and down, and the moving rod drives the trapezoidal plate to move reciprocatingly up and down to squeeze the Chinese herbal medicine in the squeezing tank. After the squeezing is completed, the connecting rod is pushed downward (this can be achieved by pushing the paddle plate downward), and the connecting rod drives the second sealing plate to move downward.
