Description

Technical Field

[0001] This invention relates to the field of artemisia processing equipment, and more specifically to an extrusion device for extracting artemisia. Background Technology

[0002] Artemisia argyi, the whole plant is used in medicine. It has the effects of warming the meridians, removing dampness, dispelling cold, stopping bleeding, reducing inflammation, relieving asthma, stopping cough, calming the fetus, and anti-allergy. The dried and crushed leaves of Artemisia argyi are used to make Artemisia argyi floss, which is used to make moxa sticks for moxibustion. It can also be used as a raw material for ink paste. In addition, the whole plant can be used as an insecticide or as fumigation for room disinfection and insecticide. The tender shoots and seedlings can be used as vegetables. The dried and crushed Artemisia argyi powder can also be used as a natural plant dye. In the extraction process of Artemisia argyi, extrusion is an important processing step.

[0003] However, the existing technology has the following problems:

[0004] 1. When two rollers rotate relative to each other to squeeze the mugwort, the mugwort extract and residue that fall off one after the other are easily mixed again, resulting in a large amount of mugwort extract being absorbed on the mugwort residue, which causes a certain degree of waste of mugwort extract.

[0005] 2. When using a flat-pressure method to squeeze mugwort, it is not convenient to clean the mugwort after squeezing. Summary of the Invention

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0044] See Figure 1-12 As shown, this invention provides an extrusion device for extracting Artemisia argyi, comprising an upper pressure plate structure 1, a pressing roller 6, a lower pressure plate structure 7, and a digital display control panel 9. The upper pressure plate structure 1, the lower pressure plate structure 7, and the pressing roller 6 are arranged from top to bottom. A horizontal movement drive assembly 4 is arranged below the pressing roller 6, and a lifting drive assembly 5 for driving the pressing roller 6 to move up and down is arranged between the horizontal movement drive assembly 4 and the pressing roller 6. The horizontal movement drive assembly 4 drives the lifting drive assembly 5 and the pressing roller 6 to move horizontally synchronously. Through the above specific structural design, the extrusion of Artemisia argyi liquid is achieved by applying pressure from bottom to top. The extruded Artemisia argyi extract flows downward to the lower pressure plate structure 7 for solid-liquid separation and export, which can avoid the extruded Artemisia argyi extract from remaining on the Artemisia argyi residue. The horizontal movement drive assembly 4, the lifting drive assembly 5, and the pressing roller 6 work together to roll and press the lower pressure plate structure 7, so that every part of the Artemisia argyi between the upper pressure plate structure 1 and the lower pressure plate structure 7 can be extruded, resulting in uniform extrusion.

[0045] When the lifting drive assembly 5 drives the compaction roller 6 to move to the highest position, the upper side of the compaction roller 6 abuts against and pushes the lower pressure plate structure 7 to move upward, and the upper surface of the lower pressure plate structure 7 abuts against the lower surface of the upper pressure plate structure 1.

[0046] The lower pressure plate structure 7 is used to screen the extract and Artemisia argyi residue. A liquid separation conduit structure 8 is provided on one side of the lower pressure plate structure 7 to separate and discharge the extract and cleaning waste liquid. A cleaning brush assembly 2 is provided at the top of the lifting drive assembly 5 to clean and scrub the upper surface of the lower pressure plate structure 7.

[0047] It also includes an outer shell 10, which is a hollow cuboid shape. An upper pressure plate structure 1 is set on the upper part of the outer shell 10. An inlet / outlet 11 is opened on one side of the upper part of the outer shell 10. A cover plate 12 is rotatably set at the inlet / outlet 11. Furthermore, the cover plate 12 is made of transparent tempered glass. A handle 13 is fixedly set on the outer side wall of the cover plate 12. Base posts 14 are fixedly set at the four corners of the outer shell 10.

[0048] The upper pressure plate structure 1 includes a first hydraulic cylinder 1a fixedly installed on the top of the outer shell 10. The push rod head of the first hydraulic cylinder 1a extends downward into the outer shell 10 and is fixedly connected to an upper pressure plate 1c. Two first guide rods 1b are symmetrically distributed on both sides of the first hydraulic cylinder 1a with the cylinder as the center. The lower ends of the two first guide rods 1b are fixedly connected to the upper side of the upper pressure plate 1c. The upper ends of the two first guide rods 1b are slidably connected to the first guide sliding holes opened at corresponding positions on the top of the outer shell 10. The output end of the digital display control panel 9 is electrically connected to the input end of the first hydraulic cylinder 1a. Through the above-mentioned specific structural design, the digital display control panel 9 controls the extension and retraction of the push rod of the first hydraulic cylinder 1a, which can drive the upper pressure plate 1c to move up and down. The height of the lower pressure plate structure 7 can be adjusted by the lifting drive component 5 and the rolling roller 6, thereby adjusting the gap between the upper pressure plate 1c and the lower pressure plate structure 7. When the mugwort is spread thickly, the gap between the upper pressure plate 1c and the lower pressure plate structure 7 is increased, and when the mugwort is spread thinly, the gap between the upper pressure plate 1c and the lower pressure plate structure 7 is decreased.

[0049] The lower pressure plate structure 7 includes a second pressure plate 701 and a solid-liquid separation sieve plate 702 arranged from bottom to top; furthermore, both the second pressure plate 701 and the solid-liquid separation sieve plate 702 are rectangular in shape, as shown in the appendix of the instruction manual. Figure 2 and 4 As shown, under the drive of the horizontal moving drive assembly 4, the rolling roller 6 rolls along the length direction of the second pressure plate 701 and the solid-liquid separation screen plate 702.

[0050] A number of fourth guide rods 706 arranged in a rectangular array are fixedly connected to the lower side of the solid-liquid separation sieve plate 702. The lower ends of these fourth guide rods 706 are slidably connected to the fourth guide holes 709 opened at corresponding positions on the second pressure plate 701. A second spring 707 is nested on the outer side of each of the fourth guide rods 706 located between the second pressure plate 701 and the solid-liquid separation sieve plate 702. The two ends of the second spring 707 are fixedly connected to the second pressure plate 701 and the solid-liquid separation sieve plate 702 respectively. A number of evenly distributed drainage channels 708 are opened on the upper surface of the second pressure plate 701. In practical applications, the drainage channels 708 extend along the length of the second pressure plate 701 and are open at both ends. A number of sieve holes 705 corresponding to the drainage channels 708 are opened through the solid-liquid separation sieve plate 702. Through the above-described specific structural design, when the upper pressure plate structure 1 and the lower pressure plate structure 7 are in a separated state, the elastic force of the second spring 707 pushes the solid-liquid separation sieve plate 702 and the second pressure plate 701 into a separated state. This facilitates separating the mugwort residue from the solid-liquid separation sieve plate 702 by one end, which facilitates the downward flow of the mugwort extract and makes it easier to clean and brush the upper surface of the solid-liquid separation sieve plate 702 in conjunction with the cleaning brush plate 204. When the upper pressure plate structure 1 and the lower pressure plate structure 7 are in a contacting and pressing state, the second spring 707 is in a compressed state, and the solid-liquid separation sieve plate 702 and the second pressure plate 701 are in a contacting state. The second pressure plate 701 applies pressure between the solid-liquid separation sieve plate 702 and the upper pressure plate 1c.

[0051] The second pressure plate 701 is rectangular in shape. The lower four corners of the second pressure plate 701 are fixedly connected to the fifth guide rods 710. Each fifth guide rod 710 is provided with a guide support rod 703 on its lower side. The lower end of the guide support rod 703 is fixedly connected to the bottom surface inside the outer shell 10. The lower end of the fifth guide rod 710 is slidably connected to the fifth guide sliding hole opened at the top of its corresponding guide support rod 703. A second limiting sleeve 704 is slidably sleeved on the outer side of each fifth guide rod 710. An adjusting bolt 711 for abutting and tightening the fifth guide rod 710 is threaded on the outer wall of the second limiting sleeve 704. Through the above-mentioned specific structural design, the position of the second limiting sleeve 704 on the outside of the fifth guide rod 710 can be adjusted, thereby adjusting the lowest position height of the second pressure plate 701 and the solid-liquid separation screen plate 702. This allows for mutual adjustment of the height between the upper surface of the solid-liquid separation screen plate 702 and the lower side of the cleaning plate 204. When the cleaning plate 204 is at a certain distance from the solid-liquid separation screen plate 702, the cleaning plate 204 can spread the mugwort on the upper surface of the solid-liquid separation screen plate 702. When the cleaning plate 204 and the solid-liquid separation screen plate 702 are in contact with each other, the cleaning plate 204 can clean the mugwort residue on the upper surface of the solid-liquid separation screen plate 702 and scrape it out to the sliding hopper 712.

[0052] The liquid distribution conduit structure 8 includes two collection pipes 801 distributed at both ends of the drainage channel 708. A sliding hopper 712 is provided on one side of each collection pipe 801, and the upper side of the sliding hopper 712 is fixedly mounted on the upper side of the guide rod 703. Universal telescopic pipes 802 are fixedly connected to the lower ends of each collection pipe 801. To accommodate the height extension and retraction of the lower pressure plate structure 7, a rectangular ring pipe 805 is connected between the lower ends of the four universal telescopic pipes 802. A liquid guide pipe 804 is connected to both ends of the rectangular ring pipe 805 along its length. A solenoid valve 803 is provided on the liquid guide pipe 804. A pipe tilt angle adjustment component 3 for rotational support and tilt angle adjustment is provided in the middle of the rectangular ring pipe 805. A second opening groove 10b for the liquid guide pipe 804 to pass through is provided on the outer wall of the outer casing 10. Specifically, the two liquid guide pipes 804 are used for the extraction of Artemisia argyi extract and waste liquid, respectively.

[0053] When the extract of Artemisia argyi is discharged through one of the liquid guide tubes 804, the tilt angle adjustment component 3 adjusts the tilt angle of the rectangular ring tube 805 so that the liquid guide tube 804 is located at a lower position, which can avoid residual liquid in the rectangular ring tube 805.

[0054] Similarly, when the waste liquid is discharged through another liquid guide tube 804, the rectangular ring tube 805 is tilted again by the tube tilt angle adjustment component 3 so that the liquid guide tube 804 is in a lower position.

[0055] Two pipe tilt angle adjustment components 3 are provided, and the two pipe tilt angle adjustment components 3 are distributed on both sides along the width direction at the middle position of the rectangular ring pipe 805. The pipe tilt angle adjustment component 3 includes a base 301 set on the bottom surface inside the outer shell 10. An L-shaped support rod 302 and a U-shaped bracket 305 are fixedly installed on the upper side of the base 301. The U-shaped opening of the U-shaped bracket 305 faces upward and a pipe fixing sleeve 306 is rotatably installed inside the U-shaped opening.

The output end of the digital display control panel 9 is electrically connected to the input end of the electric telescopic rod 303.

[0056] The horizontal movement drive assembly 4 includes a lead screw 403. One end of the lead screw 403 is driven to rotate by a second motor 402 fixedly installed inside the housing 10. A horizontal movement bracket 401 is threaded onto the lead screw 403. Two second guide rods 404 are symmetrically distributed on both sides of the lead screw 403 with the lead screw as the center. The two ends of the two second guide rods 404 are respectively fixedly connected to the inner wall of the housing 10. The two second guide rods 404 slide through the second guide sliding holes opened at corresponding positions in the horizontal movement bracket 401. The output end of the digital display control panel 9 is electrically connected to the input end of the second motor 402.

[0057] A roller shaft 6a is connected to the central axis of the compaction roller 6. The lifting drive assembly 5 includes two shaft support blocks 502. The two ends of the roller shaft 6a are rotatably connected to the two shaft support blocks 502 via bearings. A lifting support 501 is provided below each shaft support block 502. The bottom side of the lifting support 501 is fixedly connected to the horizontal moving bracket 401. A second hydraulic cylinder 503 is provided inside the lifting support 501. The push rod head of the second hydraulic cylinder 503 faces upward and is fixedly connected to a first spring 504. The upper end of the first spring 504 is fixedly connected to the shaft support block 502. On the lower side of the second hydraulic cylinder 503, two third guide rods 505 are symmetrically distributed around it. The lower ends of the two third guide rods 505 are fixedly connected to the top side of the lifting support 501. Support ears 506 are fixedly provided on both sides of the shaft support block 502. Each support ear 506 has a third guide hole that guides the sliding of the two third guide rods 505. A first limiting sleeve 507 is fixedly provided at the top of each third guide rod 505. The output end of the digital display control panel 9 is electrically connected to the input end of the second hydraulic cylinder 503. Specifically, the first spring 504 can achieve elastic compression between the upper pressure plate structure 1 and the lower pressure plate structure 7, avoiding rigid compression that could cause mechanical damage to the entire device.

[0058] The cleaning assembly 2 includes a motor bracket 201. The lower end of the motor bracket 201 is fixedly connected to the upper side of the shaft support block 502. A first motor 202 is fixedly mounted on the motor bracket 201. The output shaft end of the first motor 202 faces upward and is fixedly connected to a cleaning brush seat rod 203.

For the specific structure described above, please refer to the appendix of the instruction manual. Figure 4As shown, the cleaning brush holder 203 is in a retracted state at this time. The output shaft of the first motor 202 can rotate the cleaning brush holder 203 to the upper surface of the lower pressure plate structure 7, so that the upper surface of the lower pressure plate structure 7 can be cleaned or washed by the cleaning brush plate 204 or the cleaning nozzle 207. After use or when squeezing the mugwort, the cleaning brush holder 203 can be retracted again.

[0059] When the lifting drive assembly 5 drives the compaction roller 6 to descend to its lowest position, the upper side of the compaction roller 6 and the lower side of the lower pressure plate structure 7 disengage from each other.

[0060] Working principle:

[0061] In use, the lifting drive assembly 5 first drives the crushing roller 6 to descend to the lowest position. When the lower pressure plate structure 7 loses the support force of the crushing roller 6, the second pressure plate 701 and the solid-liquid separation screen plate 702 move downward along the axial direction of the guide rod 703. When the second limiting sleeve 704 abuts against the upper end of the guide rod 703, the second pressure plate 701 reaches the lowest position of movement. At this time, the mugwort to be extracted is spread evenly on the upper surface of the solid-liquid separation screen plate 702. At this time, the horizontal movement drive assembly 4 can drive the lifting drive assembly 5 and the crushing roller 6 to move the cleaning assembly 2. The cleaning assembly 2 can spread the mugwort evenly on the surface of the solid-liquid separation screen plate 702, clean the mugwort on the surface of the solid-liquid separation screen plate 702, and clean the upper surface of the solid-liquid separation screen plate 702.

[0062] After the cleaning component 2 evenly spreads the mugwort on the surface of the solid-liquid separation sieve plate 702, the lifting drive component 5 drives the pressing roller 6 to move upward, causing the pressing roller 6 to push the lower pressure plate structure 7 upward and abut against the lower surface of the upper pressure plate 1c of the upper pressure plate structure 1. The pressing roller 6 moves horizontally under the drive of the horizontal movement drive component 4, thereby increasing the pressure and squeezing the mugwort between the upper pressure plate structure 1 and the lower pressure plate structure 7. The liquid inside the mugwort is squeezed out, and the squeezed mugwort liquid falls into the drainage channel 708 through the sieve hole 705. The drainage channel 708 guides the squeezed mugwort liquid into the liquid distribution conduit structure 8 for discharge. After the squeezing is completed, the lifting drive component 5 drives the pressing roller 6 and the lower pressure plate structure 7 to descend, and the horizontal movement drive component 5 drives the pressing roller 6 and the lower pressure plate structure 7 to descend. Driven by component 4, the cleaning component 2 moves horizontally to clean the upper surface of the lower pressure plate structure 7, and the mugwort is cleaned from the upper surface of the lower pressure plate structure 7 and discharged into the sliding hopper 712. Further, driven by the horizontal movement drive component 4, the cleaning pipe 205 and cleaning nozzle 207 of the cleaning component 2 move horizontally to clean the upper surface of the lower pressure plate structure 7. The waste liquid generated during cleaning is collected and discharged by the liquid separation conduit structure 8. The liquid separation conduit structure 8 can discharge the squeezed mugwort extract and the waste liquid generated during cleaning separately through two liquid guide pipes 804. The pipe tilt angle adjustment component 3 can adjust the tilt angle of the rectangular ring pipe 805 to discharge the squeezed mugwort extract and the waste liquid generated during cleaning separately through two liquid guide pipes 804.
