The bottom of the feeding cylinder 1 is provided with a feeding pipe 2, the feeding pipe 2 serves as a channel for the liquid raw materials of the oral liquid to enter the feeding cylinder 1, realizes the directional conveying of the raw materials from the external storage tank to the inside of the feeding cylinder 1, provides raw material supply for the feeding process, the bottom of the feeding cylinder 1 is provided with a discharging groove 9, the discharging groove 9 serves as a channel for discharging the raw materials in the feeding cylinder 1, directionally conveys the oral liquid raw materials after quantitative control to subsequent processing devices (such as a liquid preparation tank, a pre-filling buffer tank), completes the output of the raw materials in the feeding link, the top of the discharging groove 9 and the output end of the feeding pipe 2 are both provided with a one-way valve, the one-way valve at the output end of the feeding pipe 2 prevents the oral liquid raw materials in the feeding cylinder 1 from flowing back to the external storage tank through the feeding pipe 2 in the reverse direction, avoids the pollution and waste of the raw materials, guarantees the one-way nature of the raw material conveying, the one-way valve at the top of the discharging groove 9 prevents the oral liquid raw materials discharged through the discharging groove 9 from flowing back to the feeding cylinder 1 in the reverse direction, simultaneously avoids the external impurities from entering the inside of the feeding cylinder 1 to pollute the raw materials, guarantees the cleanliness and one-way nature of the raw material conveying.

[0012] The quantitative conveying mechanism 8 includes a moving partition plate 81 and a piston 82. The moving partition plate 81 adjusts the space separation state in the inside of the feeding cylinder 1 by adjusting the height position of itself, thereby adjusting the volume of single feeding, and provides a structural basis for segmented quantitative feeding. The piston 82 moves along the inner wall of the feeding cylinder 1 under the driving of the telescopic screw rod 7, and generates extrusion force on the oral liquid raw material in the cylinder, thereby pushing the raw material to move to the direction of the discharging groove 9, and cooperating with the blocking ring 813 to realize quantitative separation of the raw material. The moving partition plate 81 includes an extension plate 811, the extension plate 811 is connected with a sliding ring 812, a blocking ring 813 and an adjusting rod 302, the rotation of the adjusting rod 302 is converted into the up-down movement of the extension plate 811, thereby driving the sliding ring 812 and the blocking ring 813 to adjust the height synchronously, realizing the adjustment of the feeding volume. The extension plate 811 is slidingly connected outside the feeding cylinder 1, and the outside of the extension plate 811 is fixedly connected with the sliding ring 812 which is slidingly connected inside the feeding cylinder 1. The sliding ring 812 realizes the sliding connection between the extension plate 811 and the feeding cylinder 1, guarantees the stability of the extension plate 811 during the up-down movement, and assists the sealing plate 816 to seal the raw material, preventing the raw material from leaking from the gap between the extension plate 811 and the feeding cylinder 1. One end of the extension plate 811 close to the inside of the feeding cylinder 1 is fixedly connected with the blocking ring 813, the blocking ring 813 separates the oral liquid raw material in the feeding cylinder 1 in space, forming independent raw material storage units. By adjusting the distance between the blocking rings 813, the precise control of the single feeding volume is realized. The top of the blocking ring 813 is a slope surface, and the top of the blocking ring 813 is fixedly connected with a plurality of baffles 814. The baffles 814 cooperate with the stop blocks 823 at the bottom of the piston 82 to limit the rotation of the convex plug 821. When the convex plug 821 contacts the top of the blocking ring 813, the rotation of the stop blocks 823 is blocked by the baffles 814, so that the piston 82 stays at the top of the specified blocking ring 813, guaranteeing the accuracy of segmented quantitative feeding. The bottom of the blocking ring 813 is fixedly connected with a connecting ring 815, the connecting ring 815 cooperates with the connecting groove 822 at the bottom of the piston 82, and by switching the different patterns (rough pattern, smooth pattern) on the outside, the connection and separation control between the convex plug 821 and the blocking ring 813 is realized, thereby completing the quantitative release of the raw material. The upper and lower sides of the extension plate 811 are fixedly connected with the sealing plates 816, the sealing plates 816 seal the gap between the extension plate 811 and the feeding cylinder 1, preventing the oral liquid raw material in the feeding cylinder 1 from leaking from the gap, and maintaining the sealing state during the up-down movement of the extension plate 811, guaranteeing the sealing property of the raw material storage. The inside of the feeding cylinder 1 is fixedly connected with a sliding rail 817, and the sealing plate 816 is slidingly connected inside the sliding rail 817. The sliding rail 817 provides guidance and support for the sliding of the sealing plate 816, limits the movement track of the sealing plate 816, ensures the stability of the sealing plate 816 during the movement with the extension plate 811, and guarantees the persistence of the sealing effect.The length of the sealing plate 816 is twice the distance that the convex plug 821 can move, and the length of the sliding rail 817 is three times the distance that the convex plug 821 can move.

[0013] The piston 82 includes a convex plug 821, which is a core component of the piston 82 and is attached to the inner wall of the feeding cylinder 1 to extrude the raw material during movement. The convex plug 821 is fixedly connected to a connecting groove 822 at the top, which cooperates with the connecting ring 815 at the bottom of the blocking ring 813. The inner side of the connecting groove 822 is adapted to the outer side of the connecting ring 815 to achieve the connection and separation of the convex plug 821 and the blocking ring 813, control the release time of the raw material, and ensure the segmented and quantitative conveying. The bottom of the convex plug 821 is fixedly connected to a stop block 823, which is adapted to the shape of the baffle 814. The stop block 823 cooperates with the baffle 814 at the top of the blocking ring 813 to limit the rotation of the convex plug 821 when it contacts the blocking ring 813, so that the piston 82 can accurately stop at the specified position and provide a position reference for subsequent segmented feeding. The outer side of the connecting ring 815 is sequentially provided with rough and smooth textures from top to bottom. The rough texture on the outer side of the connecting ring 815 tightly fits the inner side of the connecting groove 822 when the convex plug 821 is connected to the blocking ring 813, increasing the friction between them and ensuring that the convex plug 821 is stably fixed at the bottom of the blocking ring 813 to prevent the raw material from leaking prematurely. The smooth texture on the outer side of the connecting ring 815 reduces the friction with the inner side of the connecting groove 822 when the convex plug 821 needs to be separated from the blocking ring 813, allowing the convex plug 821 to smoothly separate from the blocking ring 813 and ensure that the raw material is released to the discharge chute 9 on time. The inner side of the connecting groove 822 is adapted to the shape of the outer side of the connecting ring 815.

[0014] The support frame 3 comprises a mounting ring 301, an adjusting rod 302 and a support ring 303. The mounting ring 301 is fixedly connected to the bottom outer side of the feeding cylinder 1, and is used to realize the fixed connection between the feeding device and the processing device requiring feeding, to provide mounting and positioning for the device as a whole, to ensure the stable assembly of the device on the processing equipment, to guarantee the stability of the feeding process. The adjusting rod 302 is rotatably connected to the top of the mounting ring 301, and a threaded groove is arranged in the middle segment of the adjusting rod 302. The adjusting rod 302 converts the rotary motion into the up-down linear motion of the extension plate 811 by rotating itself, to provide power transmission for the height adjustment of the movable partition plate 81, to realize the adjustment of the distance between the blocking rings 813, and to further control the feeding volume. The threaded groove in the middle segment of the adjusting rod 302 cooperates with the threaded structure at the outer end of the extension plate 811, to convert the rotation of the adjusting rod 302 into the up-down movement of the extension plate 811, to provide a threaded transmission basis for the position adjustment of the extension plate 811, to guarantee the accuracy of the adjusting action. The outer end of the extension plate 811 is screw-connected to the middle segment of the adjusting rod 302. The top of the adjusting rod 302 is fixedly connected with the support ring 303. The support ring 303 provides mounting space for the components in the adjusting part 4, such as the locking ring 404, the extrusion block 405 and the rubber ring 406. At the same time, through cooperation with the extrusion block 405 and the rubber ring 406, the support ring 303 realizes the fixation of the locking ring 404, and guarantees the locking function of the adjusting part 4.

[0015] The adjusting part 4 comprises a concave frame 401, which provides mounting support for a pressing stud 403 and is connected with the supporting ring 303 through a bolt 402 to ensure the position fixation between the adjusting rod 302, the supporting ring 303 and the concave frame 401, and provides a stable foundation for the threaded transmission of the pressing stud 403. The concave frame 401 is fixedly connected to the top outer side of the adjusting rod 302, and the inside of the concave frame 401 is provided with the bolt 402, and the other end of the bolt 402 is connected with the outside of the supporting ring 303. The bolt 402 connects the concave frame 401 and the supporting ring 303 to limit the relative movement between the concave frame 401 and the supporting ring 303, ensure the position fixation of the concave frame 401 on the top of the adjusting rod 302, and provide a stable mounting frame for the adjusting action of the pressing stud 403. The top of the concave frame 401 is threadedly connected with the pressing stud 403. The pressing stud 403 generates an axial downward pressure by rotating through its own thread, pushes the locking ring 404 to move downward along the outer side of the adjusting rod 302, provides driving force for the locking ring 404 to extrude the extrusion block 405, realizes the locking action of the adjusting part 4, and the outer side of the adjusting rod 302 is slidably connected with the locking ring 404. The locking ring 404 moves downward under the driving of the pressing stud 403, extrudes the extrusion block 405 through the bottom outer side slope, makes the extrusion block 405 drive the rubber ring 406 to expand, and then realizes the fixation of itself in the supporting ring 303, limits the rotation of the adjusting rod 302, fixes the position of the movable partition plate 81, and the top of the locking ring 404 is rotatably connected with the bottom of the pressing stud 403. The inside of the supporting ring 303 is slidably connected with a plurality of extrusion blocks 405. The extrusion blocks 405 slide along the inside of the supporting ring 303 under the extrusion action of the locking ring 404, convert the axial pressure of the locking ring 404 into radial extrusion force on the rubber ring 406, push the rubber ring 406 to expand outward, provide power for the close contact between the rubber ring 406 and the supporting ring 303, and the outer side of the extrusion block 405 is provided with the rubber ring 406. The rubber ring 406 expands outward under the action of the extrusion block 405, tightly contacts with the rough surface inside the supporting ring 303 through the rough surface on the outer side, increases the friction, realizes the fixation of the locking ring 404, further limits the rotation of the adjusting rod 302, and guarantees the stable position of the movable partition plate 81.The inner side shape of the extrusion block 405 is matched with the outer side slope shape of the bottom of the locking ring 404, the inner side slope of the extrusion block 405 is matched with the outer side slope of the bottom of the locking ring 404, the axial downward movement of the locking ring 404 is converted into the radial outward sliding of itself, the pressure of the locking ring 404 can be effectively transmitted to the extrusion block 405, the rubber ring 406 is driven to expand, and the outer side of the rubber ring 406 is provided with a rough surface, the outer side rough surface of the rubber ring 406 increases the friction between the rubber ring 406 and the inside of the support ring 303, after the rubber ring 406 expands, the fixing stability of the locking ring 404 in the support ring 303 is improved through the close contact of the rough surface, the locking ring 404 is prevented from loosening to cause the rotation of the adjusting rod 302, and the inside rough surface of the support ring 303 is in contact with the outer side rough surface of the rubber ring 406, the inside rough surface of the support ring 303 cooperates with the outer side rough surface of the rubber ring 406 to further increase the friction therebetween, the fixing effect of the rubber ring 406 on the locking ring 404 is strengthened, and the rotation of the adjusting rod 302 in the working process is prevented, so that the feeding accuracy is ensured.

[0016] Working principle: first, the whole feeding device is installed on the processing device which needs to be fed through the mounting ring 301, then the liquid raw material is fed into the inside of the feeding cylinder 1 through the inlet of the feeding pipe 2, then the feeding amount of different batches is calculated, the locking ring 404 at the top of the adjusting rod 302 is rotated to drive the adjusting rod 302 to rotate, the adjusting rod 302 drives the extension plate 811 to move up and down, so as to drive the sliding ring 812 and the blocking ring 813 to synchronously adjust the height position, and at the same time, the sealing plate 816 also moves synchronously with the extension plate 811, and because the length of the sealing plate 816 is twice the movement distance of the extension plate 811, no matter how the sliding ring 812 and the blocking ring 813 move, the liquid raw material always keeps a sealed state in the inside of the feeding cylinder 1 and cannot leak, and the space size between the plurality of blocking rings 813 (that is, the feeding volume of single feeding) is adjusted.

[0017] And after the adjustment is completed, the locking ring 404 is lowered into the inside of the support ring 303 along the outer side of the adjusting rod 302 by rotating the lower pressing stud 403, and the rubber ring 406 is expanded outward by the outward extrusion of the extrusion block 405 by the bottom of the locking ring 404, so that the locking ring 404 can be kept stable and cannot rotate through the rough surface, so as to avoid that the position of the moving partition plate 81 is disturbed by external factors to produce up and down swing in the feeding process, and the accuracy of the feeding amount is affected.

[0018] When the motor 6 is turned on again, the motor 6 drives the telescopic screw 7 to rotate and extend downward, so as to drive the first piston 82 to rotate and move downward synchronously, and when the first convex plug 821 contacts the top of the blocking ring 813, the rotation of the convex plug 821 is limited by the contact between the baffle 814 and the stop block 823, so that the first piston 82 stops at the top of the first blocking ring 813, and the telescopic screw 7 continues to move downward until it contacts the center of the second convex plug 821, and because there is friction between the outer side of the convex plug 821 and the inner wall of the feeding cylinder 1, the telescopic screw 7 gradually rotates into the middle part of the second convex plug 821 while driving the second convex plug 821 to rotate, so that the contact surface between the connecting ring 815 and the connecting groove 822 gradually changes from rough lines to smooth lines, when the contact surface between the connecting ring 815 and the connecting groove 822 completely changes into smooth lines, that is, the bottom of the telescopic screw 7 is flush with the bottom of the convex plug 821, the convex plug 821 is separated from the bottom of the blocking ring 813, and moves downward with the telescopic screw 7, so that the raw liquid enters the discharging groove 9, so that the segmented quantitative feeding of the raw material of the oral liquid can be realized by adjusting the distance between the blocking rings 813, and the demand for different feeding amounts at different times in a single feeding operation can be met.

[0019] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, as long as they are within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc. should be included in the protection scope of the present application.
