Description

Technical Field

[0002] Sea cucumber polysaccharide is a natural functional polysaccharide with high biological activity, thermal sensitivity, and structural complexity, and its application in industries such as food, medicine, and health products is becoming increasingly widespread.

[0003] In the existing sea cucumber polysaccharide extraction device, after ethanol precipitation, centrifugation, and washing, the precipitate (rich in sea cucumber polysaccharide) is dried. When the existing sea cucumber polysaccharide extraction device dries the precipitate, the precipitate is often manually taken out and transferred to the drying equipment. In this process, the precipitate is likely to adsorb pollution particles or microorganisms in the air, and the washed precipitate is wet and loose in texture, and manual loading is likely to be uneven, resulting in uneven thickness of the liquid film, large differences in moisture content after freeze-drying, and it is difficult for manual operation or disturbance of the precipitate during the freeze-drying stage, which is not conducive to improving the drying efficiency of the precipitate, that is, it is not easy to improve the extraction efficiency of sea cucumber polysaccharide.

[0010] Furthermore, one end of the spray head group is fixedly connected to a multi-stage telescopic cylinder.

[0014] A method for extracting sea cucumber polysaccharide specifically includes the following steps: Step 1: Start the driving motor to move the plugging plate towards the driving motor along the surface of the first lead screw until the plugging plate moves to the set position. Then start the multi-stage telescopic cylinder to drive the corresponding spray head group to move above the corresponding rectangular tray. When the orthographic projection of the spray head group completely coincides with the orthographic projection of the rectangular tray, convey the precipitation raw materials inside the reaction kettle to the inside of the spray head group through the pipeline, the liquid separation pipe and the feeding pipe. By controlling the telescopic of the multi-stage telescopic cylinder, evenly distribute the precipitation raw materials into the corresponding rectangular tray; Step 2: When the multi-stage telescopic cylinder drives the spray head group to move forward in Step 1, the feeding pipe moves accordingly with the spray head group and drives the adjusting sleeve to rotate on the surface of the constraint rod. The rotation of the adjusting sleeve guides and constrains the guide ball head through the inner wall of the spiral groove, causing the adjusting sleeve to move along the central axis of the constraint rod, and increasing the elastic potential energy of the first torsion spring through the multi-stage telescopic rod and the connecting ring; When the multi-stage telescopic cylinder drives the spray head group to move backward, the elastic potential energy of the first torsion spring causes the adjusting sleeve to rotate. Through the guiding and constraining of the guide ball head by the inner wall of the spiral groove, the feeding pipe winds around the surface of the constraint rod along the inner wall of the spiral groove; Step 3: When the freeze-drying device is performing freeze-drying work, by changing the direction of the current passing through the electromagnet, the third slider drives the connecting bar to move inside the first cylindrical block, so that the second slider drives the flexible sweeping piece on the rectangular plate to scrape the bottom surface of the corresponding rectangular tray, causing the rectangular tray to vibrate.

[0015] Step 4: When the freeze-drying work inside the freeze-drying device is completed, open the door of the freeze-drying device to reset the third spring rod from the compressed state to the normal state. Under the action of the elastic potential energy of the second spring, the top block on the surface of the adjusting rod slides into the second chute, causing the first slider to move down to the lowest position inside the third chute, so that only the hemispherical part of the positioning column is located in the first circular groove on the surface of the positioning bar. Pull out the rectangular tray horizontally from the freeze-drying device and insert a new rectangular tray horizontally into the corresponding position. Close the door of the freeze-drying device, and the third spring rod compresses and drives the top block on the surface of the adjusting rod to slide towards the first slider, and pushes the first slider upwards, so that the cylindrical part of the positioning column is located in the first circular groove opened on the surface of the positioning bar, improving the horizontal binding force on the rectangular tray.

[0016] The above solution of the present invention has at least the following beneficial effects: In the above solution of the present invention, through the cooperation of components such as the cloth box, the spray head group, the multi-stage telescopic cylinder, the adjusting door body and the plugging plate, the feeding is automatically operated inside the device, reducing the pollution of impurity particles or microorganisms in the air. By the multiple-layer feeding of the spray head group, a uniform liquid film is formed, accelerating the freezing process, reducing the difference in the thickness of the liquid film, and improving the efficiency of the freeze-drying process in the extraction process of sea cucumber polysaccharide; The cooperation of components such as the feeding pipe, the restraining rod, the spiral groove, the adjusting sleeve, the guiding ball head and the first torsion spring enables the nozzle group to remain stable during the coating raw material stage, reduces movement interference, improves the automation level of the device, and further improves the extraction efficiency of sea cucumber polysaccharide; The cooperation of components such as the supporting strip, the adjusting rod, the top block, the first slider, the positioning column and the first spring enables the device to easily pick up and place the rectangular tray, and at the same time, keeps the rectangular tray stable during the freeze-drying stage, which is beneficial to improving the extraction efficiency of sea cucumber polysaccharide.

[0028] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0029] As Figures 1 to 10 shown, an extraction device for sea cucumber polysaccharide according to an embodiment of the present invention includes a mounting frame 101, a reaction kettle 102 and a freeze-drying device 103 are mounted on the surface of the mounting frame 101, and a plurality of rectangular trays 104 are arranged in parallel inside the freeze-drying device 103, including: An adjusting door body 201 is arranged on one side of the freeze-drying device 103, a cloth feeding box 202 is arranged on the side of the adjusting door body 201 away from the freeze-drying device 103, a sprinkler head group 402 corresponding to the number of the rectangular trays 104 is arranged inside the cloth feeding box 202, and the communication or isolation between the cloth feeding box 202 and the inside of the freeze-drying device 103 is adjusted through the adjusting door body 201; When the cloth feeding box 202 is in communication with the inside of the freeze-drying device 103, the sprinkler head group 402 moves into the inside of the freeze-drying device 103 and feeds materials into the inside of the corresponding rectangular tray 104. When the cloth feeding box 202 is isolated from the inside of the freeze-drying device 103, the sprinkler head group 402 contracts into the inside of the cloth feeding box 202. The sprinkler head group 402 feeds materials into the inside of the corresponding rectangular tray 104 multiple times during the freeze-drying stage to improve the freezing efficiency of the precipitated raw materials; Constraint rods 405 corresponding to the number of the sprinkler head groups 402 are arranged inside the cloth feeding box 202, spiral grooves 410 are formed on the surfaces of the constraint rods 405, feed pipes 403 are arranged on the surfaces of the sprinkler head groups 402, and the feed pipes 403 are wound around the surfaces of the constraint rods 405 through the spiral grooves 410. Adjusting sleeves 411 are arranged on the surfaces of the constraint rods 405. During the process that the feed pipes 403 follow the sprinkler head groups 402 and move into the inside of the cloth feeding box 202, the feed pipes 403 and the constraint rods 405 are constrained by the adjusting sleeves 411 at fixed positions on the surfaces of the constraint rods 405; A plurality of flexible scraping sheets 504 are provided on the bottom surface of the rectangular tray 104. The flexible scraping sheets 504 are used to scrape the bottom surface of the corresponding rectangular tray 104, so as to vibrate the rectangular tray 104.

[0030] In the embodiment of the present invention, when extracting sea cucumber polysaccharide, the processed sea cucumber raw materials are put into the interior of the reaction kettle 102. When laying the precipitated raw materials completed in the reaction in the interior of the reaction kettle 102 in the rectangular tray 104, the freeze-drying device 103 is communicated with the interior of the cloth box 202 by adjusting the door body 201. The precipitated raw materials are evenly laid in the interior of the rectangular tray 104 through the nozzle group 402. After the laying is completed, the adjusting door body 201 isolates the cloth box 202 from the interior of the freeze-drying device 103, and the freeze-drying device 103 is started to make the freeze-drying device 103 start the freeze-drying work; In the pre-freezing stage inside the freeze-drying device 103, the adjusting door body 201 is opened multiple times to make the nozzle group 402 feed materials into the corresponding rectangular tray 104. Each time of feeding forms a liquid film. After the liquid film is frozen, the next feeding is carried out until the thickness of the frozen raw materials inside the rectangular tray 104 reaches the set value. At this time, the pressure is increased and the temperature is raised to enter the sublimation drying stage; When the nozzle group 402 moves inside the cloth box 202 and the freeze-drying device 103, by moving the adjusting sleeve 411 on the surface of the restraining rod 405, when the material conveying pipe 403 follows the movement of the nozzle group 402, it is released from the spiral groove 410 on the surface of the restraining rod 405 or wound around the surface of the restraining rod 405 along the extension direction of the spiral groove 410, so as to prevent the material conveying pipe 403 from interfering with the opening and closing of the adjusting door body 201 and the movement of the nozzle group 402; In the stage of the nozzle group 402 feeding materials into the rectangular tray 104 and the freezing stage and drying stage of the freeze-drying device 103, the bottom surface of the rectangular tray 104 is scraped by the flexible scraping sheets 504, so as to vibrate the rectangular tray 104. The vibration of the rectangular tray 104 makes the nozzle group 402 spray the precipitated raw materials into the interior of the rectangular tray 104 and then distribute more evenly in the interior of the rectangular tray 104, so as to ensure that the thickness of each layer of liquid film laid is uniform. In the drying stage, the vibration of the rectangular tray 104 makes the raw materials on the surface layer of the interior of the rectangular tray 104 that are dried first become loose, so as to dredge the internal water vapor channels of the raw materials and improve the drying efficiency. At the same time, the vibration of the rectangular tray 104 makes the ice crystal layer break, so that the released gas escapes more smoothly. As the drying work continues, the powder located above begins to become loose under the influence of the vibration of the rectangular tray 104, which is beneficial to the migration of bound water from the interior to the surface layer, and at the same time shortens the residence time of water vapor desorption and reduces the re-adsorption of water vapor.

[0031] The freeze-drying device 103 and the cloth box 202 are both fixedly connected in the first through hole formed on the surface of the adjusting door body 201. A plugging plate 203 is slidably connected inside the adjusting door body 201. A driving motor 205 is installed on the surface of the adjusting door body 201. The end of the output shaft of the driving motor 205 is fixedly connected with a first lead screw 204. The first lead screw 204 is rotationally connected inside the adjusting door body 201 through a first bearing. The first lead screw 204 is threadedly connected in the first thread groove formed on the surface of the plugging plate 203.

[0032] In the embodiment of the present invention, by starting the driving motor 205, the first lead screw 204 rotates. The rotation of the first lead screw 204 causes the plugging plate 203 on its surface to move inside the adjusting door body 201. The communication situation between the cloth box 202 and the inside of the freeze-drying device 103 is adjusted by blocking or unblocking the first through hole formed on the surface of the adjusting door body 201 by the plugging plate 203.

[0033] A plurality of groups of supporting bars 301 are arranged in parallel inside the freeze-drying device 103. Each group of supporting bars 301 is symmetrically arranged inside the freeze-drying device 103. Each group of supporting bars 301 is used to support the corresponding rectangular tray 104. A plurality of positioning columns 310 are arranged on the surface of the supporting bar 301. Positioning bars 206 are symmetrically and fixedly connected to the surface of the rectangular tray 104. The positioning columns 310 are inserted into the corresponding first circular grooves formed on the surface of the positioning bars 206.

[0034] In the embodiment of the present invention, the supporting bar 301 is fixed on the inner wall of the freeze-drying device 103 through a fixing bar. The positioning columns 310 are inserted into the first circular grooves formed on the surface of the positioning bars 206 to generate a horizontal constraint on the rectangular tray 104, so as to keep the rectangular tray 104 stable in the horizontal direction when the feeding pipe 403 scrapes the bottom surface of the rectangular tray 104.

[0035] A third chute 307 is formed inside the supporting bar 301. A first slider 308 is slidably connected inside the third chute 307. The positioning column 310 is slidably connected in the second circular groove formed on the surface of the first slider 308. A first spring 309 is arranged in the second circular groove formed on the surface of the first slider 308. The two ends of the first spring 309 are respectively fixedly connected to the positioning column 310 and the first slider 308. The positioning column 310 is slidably connected in the third circular groove formed on the surface of the supporting bar 301.

[0036] A first sliding groove 303 is formed inside the supporting strip 301. An adjusting rod 304 is slidably connected inside the first sliding groove 303. A second spring 311 is arranged inside the first sliding groove 303. Two ends of the second spring 311 are fixedly connected to the adjusting rod 304 and the supporting strip 301 respectively. A second sliding groove 306 is formed inside the supporting strip 301. A plurality of top blocks 305 are fixedly connected to the surface of the adjusting rod 304. The top blocks 305 are respectively located inside the corresponding second sliding grooves 306. One end of the adjusting rod 304 away from the second spring 311 is fixedly connected to a third spring rod 312. The third spring rod 312 abuts against the door body of the freeze-drying device 103.

[0037] In an embodiment of the present invention, when the door body of the freeze-drying device 103 is opened, the third spring rod 312 returns to its natural length under the action of its elastic potential energy, and under the action of the elastic potential energy of the second spring 311, the adjusting rod 304 is pushed to move in a direction away from the second spring 311. During this process, the top block 305 slides into the second sliding groove 306 from inside the third sliding groove 307. When the top block 305 leaves the bottom surface of the first slider 308, the first slider 308 slides downward along the inside of the third sliding groove 307 under the action of gravity, and drives the positioning post 310 to move downward until the bottom surface of the first slider 308 contacts the inner wall of the third sliding groove 307. At this time, only the hemispherical part of the positioning post 310 is located in the first circular groove formed on the surface of the positioning strip 206. When the rectangular tray 104 drives the positioning strip 206 to slide along the surface of the supporting strip 301, under the extrusion of the positioning strip 206, the positioning post 310 compresses the first spring 309 downward until the positioning post 310 is inserted into the first circular groove formed on the surface of the positioning strip 206 under the action of the elastic potential energy of the first spring 309; When the door of the freeze-drying device 103 is closed, the third spring rod 312 is compressed under the extrusion of the door body, and drives the adjusting rod 304 to move in a direction of compressing the second spring 311. During this process, the top block 305 slides from inside the second sliding groove 306 into the third sliding groove 307 under the drive of the adjusting rod 304, and the inclined surface of the top block 305 extrudes the inclined surface of the first slider 308, so that the first slider 308 drives the positioning post 310 to move upward along the inner wall of the third sliding groove 307 until the upper surface of the top block 305 abuts against the bottom surface of the first slider 308. At this time, the cylindrical part of the positioning post 310 is located in the first circular groove. The rectangular tray 104 is not easily moved in the horizontal direction under the constraint of the cylindrical part of the positioning post 310.

[0038] One end of the nozzle group 402 is fixedly connected to a multi-stage telescopic cylinder 401. The end of the multi-stage telescopic cylinder 401 away from the nozzle group 402 is fixedly connected to the inner wall of the cloth box 202. One end of the material conveying pipe 403 is fixedly connected to the fourth circular groove formed on the surface of the nozzle group 402. The material conveying pipe 403 is fixedly connected to the second reserved opening formed on the surface of the cloth box 202. A liquid distribution pipe 414 is arranged on one side of the cloth box 202. The material conveying pipe 403 is fixedly connected to the corresponding first through hole formed on the surface of the liquid distribution pipe 414. The liquid distribution pipe 414 is connected to the inside of the discharge port of the reaction kettle 102 through a pipeline. A protective shell 406 is fixedly connected to the surface of the constraint rod 405. Fixed arms 404 are fixedly connected to the surfaces of the constraint rod 405 and the protective shell 406. The fixed arms 404 are all fixedly connected to the cloth box 202. A connecting ring 408 is rotatably connected to the surface of the constraint rod 405 through a second bearing. A first torsion spring 407 is arranged inside the protective shell 406. Two ends of the first torsion spring 407 are respectively fixedly connected to the protective shell 406 and the connecting ring 408.

[0039] A plurality of multi-stage telescopic rods 409 are fixedly connected to the surface of the connecting ring 408 in an annular array. The ends of the multi-stage telescopic rods 409 away from the connecting ring 408 are all fixedly connected to the surface of the adjusting sleeve 411. A guiding ball head 412 is fixedly connected to the inner wall of the adjusting sleeve 411. The guiding ball head 412 abuts against the inner wall of the spiral groove 410.

[0040] Installation frames 415 corresponding to the material conveying pipes 403 in number are fixedly connected to the inner wall surface of the cloth box 202. Pulleys 413 are symmetrically installed inside the installation frames 415. The material conveying pipes 403 are arranged inside the corresponding installation frames 415, and the material conveying pipes 403 abut against the surfaces of the corresponding two pulleys 413.

[0041] In the embodiment of the present invention, by starting the multi-stage telescopic cylinder 401, the multi-stage telescopic cylinder 401 drives the nozzle group 402 at its end to move. When the multi-stage telescopic cylinder 401 drives the nozzle group 402 to perform an elongation movement, the nozzle group 402 drags the material conveying pipe 403 to move towards the inside of the freeze-drying device 103. The extension of the material conveying pipe 403 towards the inside of the freeze-drying device 103 will drive the adjusting sleeve 411 to rotate on the surface of the constraint rod 405, so as to unwind from the surface of the constraint rod 405, and a relative movement occurs between the constraint holes formed on the surface of the adjusting sleeve 411 and the adjusting sleeve 411. When the adjusting sleeve 411 rotates on the surface of the constraint rod 405, the guiding ball head 412 slides along the inner wall of the spiral groove 410, so that the adjusting sleeve 411 moves towards the direction close to the multi-stage telescopic cylinder 401 on the surface of the constraint rod 405. During the rotation and movement of the adjusting sleeve 411, the multi-stage telescopic rods 409 are correspondingly compressed and drive the connecting ring 408 to rotate. The rotation of the connecting ring 408 causes the first torsion spring 407 to twist, and the elastic potential energy of the first torsion spring 407 continuously increases; When the multi-stage telescopic cylinder 401 drives the nozzle group 402 to perform a contraction movement, under the action of the elastic potential energy of the first torsion spring 407, the connecting ring 408 drives the adjusting sleeve 411 to rotate through the multi-stage telescopic rod 409. Under the cooperation of the guiding ball head 412 and the spiral groove 410, the adjusting sleeve 411 moves away from the multi-stage telescopic cylinder 401, and continuously restrains the material conveying pipe 403 on the surface of the spiral groove 410; The material conveying pipe 403 is fixed in the second reserved opening formed on the surface of the cloth box 202, which is convenient for keeping the cloth box 202 isolated from the outside world. At the same time, the length of the material conveying pipe 403 inside the cloth box 202 is certain, which is convenient for the material conveying pipe 403 to be restrained in the spiral groove 410. When the material conveying pipe 403 moves following the telescopic movement of the multi-stage telescopic cylinder 401, the pulley 413 in the mounting frame 415 restrains the moving direction of the material conveying pipe 403, further avoiding the interference of the material conveying pipe 403 on the movement of other components inside the freeze-drying device 103.

[0042] A fourth sliding groove 501 is formed on the surface of the supporting strip 301. A second sliding block 502 is slidably connected inside the fourth sliding groove 501. A rectangular plate 503 is fixedly connected between two corresponding second sliding blocks 502. Flexible sweeping pieces 504 are equidistantly and fixedly connected to the surface of the rectangular plate 503. Connecting strips 505 are symmetrically arranged inside the freeze-drying device 103. The second sliding blocks 502 are fixedly connected to the corresponding connecting strips 505. A first cylindrical block 506 is fixedly connected to the inner wall surface of the freeze-drying device 103. An electromagnet 507 is embedded and installed inside the first cylindrical block 506. A third sliding block 508 is slidably connected inside the first cylindrical block 506. A magnetic block is embedded inside the third sliding block 508. The third sliding block 508 is fixedly connected to one of the connecting strips 505.

[0043] In the embodiment of the present invention, when the flexible sweeping piece 504 scrapes the rectangular tray 104, by adjusting the current direction inside the electromagnet 507, the electromagnet 507 generates suction or repulsion on the magnetic block inside the third sliding block 508, so that the third sliding block 508 moves inside the first cylindrical block 506. Furthermore, the third sliding block 508 drives the rectangular plate 503 on the surface of the second sliding block 502 to slide through the connecting strip 505. The sliding of the rectangular plate 503 enables the flexible sweeping piece 504 to scrape the bottom of the rectangular tray 104. A plurality of vibration transmission strips 207 can be evenly arranged inside the rectangular tray 104 to improve the disturbance effect on the raw materials inside the rectangular tray 104 when the rectangular tray 104 vibrates. The sliding of the second sliding block 502 inside the fourth sliding groove 501 makes the movement of the rectangular plate 503 more stable.

[0044] A method for extracting sea cucumber polysaccharide specifically includes the following steps: Step 1: Start the driving motor 205 to move the plugging plate 203 on the surface of the first lead screw 204 toward the driving motor 205 until the plugging plate 203 moves to the set position. Then start the multi-stage telescopic cylinder 401 to drive the corresponding spray head group 402 to move above the corresponding rectangular tray 104. When the orthographic projection of the spray head group 402 completely coincides with the orthographic projection of the rectangular tray 104, convey the precipitation raw materials inside the reaction kettle 102 to the inside of the spray head group 402 through pipelines, the liquid separation pipe 414, and the feeding pipe 403. By controlling the telescopic movement of the multi-stage telescopic cylinder 401, evenly distribute the precipitation raw materials into the corresponding rectangular tray 104. Step 2: When the multi-stage telescopic cylinder 401 drives the spray head group 402 to move forward in Step 1, the feeding pipe 403 moves accordingly with the spray head group 402 and drives the adjusting sleeve 411 to rotate on the surface of the constraint rod 405. The rotation of the adjusting sleeve 411 guides and constrains the guiding ball head 412 through the inner wall of the spiral groove 410, causing the adjusting sleeve 411 to move along the central axis of the constraint rod 405, and increasing the elastic potential energy of the first torsion spring 407 through the multi-stage telescopic rod 409 and the connecting ring 408. When the multi-stage telescopic cylinder 401 drives the spray head group 402 to move backward, the elastic potential energy of the first torsion spring 407 causes the adjusting sleeve 411 to rotate back. Through the guiding and constraining of the guiding ball head 412 by the inner wall of the spiral groove 410, the feeding pipe 403 winds around the surface of the constraint rod 405 along the inner wall of the spiral groove 410. Step 3: When the freeze-drying device 103 is performing freeze-drying work, by changing the direction of the current flowing through the electromagnet 507, the third slider 508 drives the connecting bar 505 to move inside the first cylindrical block 506, so that the second slider 502 drives the flexible sweeping piece 504 on the surface of the rectangular plate 503 to scrape the bottom surface of the corresponding rectangular tray 104, causing the rectangular tray 104 to vibrate.

[0045] Step 4: When the freeze-drying operation inside the freeze-drying device 103 is completed, open the door of the freeze-drying device 103 to reset the third spring rod 312 from the compressed state to the normal state. Under the action of the elastic potential energy of the second spring 311, the top block 305 on the surface of the adjusting rod 304 slides into the second chute 306, causing the first slider 308 to move down to the lowest position inside the third chute 307, so that only the hemispherical part of the positioning column 310 is located in the first circular groove on the surface of the positioning strip 206. Then, pull out the rectangular tray 104 horizontally from the freeze-drying device 103, insert a new rectangular tray 104 horizontally into the corresponding position, close the door of the freeze-drying device 103, the third spring rod 312 compresses and drives the top block 305 on the surface of the adjusting rod 304 to slide towards the first slider 308, and jacks up the first slider 308, making the cylindrical part of the positioning column 310 located in the first circular groove opened on the surface of the positioning strip 206, thereby improving the horizontal binding force on the rectangular tray 104.

[0046] It should be noted that: The reaction kettle 102 outputs the crushed sea cucumber raw materials from the discharge port after degreasing, hot water extraction, filtration, concentration, deproteinization, ethanol precipitation, centrifugation and washing. The working principle and usage method of the freeze-drying device 103 are prior arts and will not be elaborated in detail.

The output shaft of the driving motor 205 extends into the adjusting door body 201 through the first reserved hole opened on the surface of the adjusting door body 201. One end of the freeze-drying device 103 is open, facilitating the connection between the freeze-drying device 103 and the inside of the cloth box 202. The third circular groove opened on the surface of the supporting strip 301 is connected to the inside of the third chute 307 to facilitate the sliding of the positioning column 310. The spray head group 402 is composed of a round tube with both ends closed and spray heads equidistantly installed on the round tube, facilitating the spray head group 402 to evenly distribute the precipitated raw materials inside the rectangular tray 104. The adjusting sleeve 411 is tubular in shape, and its surface is provided with a restraining hole to facilitate the relative sliding of the feed pipe 403 with respect to the adjusting sleeve 411. The guiding ball head 412 is hemispherical and is arranged on one side of the restraining hole close to the spiral groove 410 to prevent the guiding ball head 412 from interfering with the feed pipe 403. The inner wall surface of the adjusting sleeve 411 is provided with a receiving groove, so that the part of the feed pipe 403 located between the adjusting sleeve 411 and the restraining rod 405 is not easily squeezed by the adjusting sleeve 411, ensuring the smooth and stable liquid discharge of the feed pipe 403. The first cylindrical block 506 is cylindrical in shape, with a cylindrical cavity formed inside it, and a rectangular groove is provided on its surface. The rectangular groove is connected to the inside of the cylindrical cavity to facilitate the sliding of the third slider 508 inside the first cylindrical block 506 and the connection between the third slider 508 and the connecting bar 505.
