Existing weighing devices generally use a liquid pump to extract the nanoemulsion in the container to weigh it. However, the flow rate of the liquid pump is affected by many factors. When the flow rate of the liquid pump is unstable, the number of nanoemulsions passing through per unit time will vary, thereby reducing the accuracy of the nanoemulsion weighing.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 3As shown, a nanoemulsion component device according to an embodiment of the utility model comprises a liquid storage tank 1; a first one-way valve 12 is fixedly connected to the side wall of the liquid storage tank 1; a liquid passage tube 13 is fixedly connected to the other end of the first one-way valve 12; a second one-way valve 14 is fixedly connected to the other end of the liquid passage tube 13; a piston cylinder 15 is fixedly connected to the middle of the liquid passage tube 13; a fixing plate 16 is fixedly connected to the side wall of the liquid storage tank 1; a first bracket 17 is fixedly connected to the top of the fixing plate 16; a bidirectional screw assembly 18 is installed in the middle of the first bracket 17; a first slider 19 is threadedly connected to the middle of the bidirectional screw of the bidirectional screw assembly 18; an end of the first slider 19 close to the piston cylinder 15 is connected to a movable rod 110 through a torsion spring; a clamping plate 111 is fixedly connected to the top and bottom of the end of the movable rod 110 close to the piston cylinder 15; an extension plate 112 is fixedly connected to the top of the piston of the piston cylinder 15; the end portion of the extension plate 112 between a pair of clamping plates 111; when working, the operation of the bidirectional screw rod assembly 18 drives the first slider 19 to move up and down, thereby driving the extension plate 112 to move up and down through the pair of clamping plates 111. When the extension plate 112 moves up, the nanoemulsion inside the liquid storage tank 1 is drawn into the interior of the liquid pipe 13 through the first one-way valve 12. When the extension plate 112 moves down, the nanoemulsion inside the liquid pipe 13 will be squeezed out through the second one-way valve 14. Since the moving path of the first slider 19 is fixed when the bidirectional screw rod assembly 18 is running, the rising and falling distances of the extension plate 112 are also fixed, so that the nanoemulsion entering the liquid pipe 13 and the nanoemulsion sprayed through the second one-way valve 14 are the same, thereby achieving accurate weight. Through the above structure, the weight of each portion of the nanoemulsion can be kept consistent, reducing the occurrence of a difference in the amount of the nanoemulsion after weighting, and making the weight of the nanoemulsion more accurate.

[0025] like Figures 1 to 3As shown, the top of the fixed plate 16 is fixedly connected to the second bracket 2; the middle part of the second bracket 2 is rotatably connected to the adjusting screw 21; the middle part of the adjusting screw 21 is threadedly connected to the second slider 22; the end of the second slider 22 is arranged facing the middle part of the movable rod 110; the end of the second slider 22 is fixedly connected to the limiting bead 23; when working, the limiting bead 23 can be moved to different heights by rotating the adjusting screw 21, and when the first slider 19 rises due to the operation of the bidirectional screw assembly 18, the middle part of the movable rod 110 will be squeezed by the limiting bead 23 when passing through the limiting bead 23 and rotated, thereby The pair of clamping plates 111 will deviate from the top and bottom of the extension plate 112. After the first slider 19 moves away from the limiting bead 23, the pair of clamping plates 111 will be reset under the action of the torsion spring. When the first slider 19 turns around and descends due to the operation of the bidirectional screw assembly 18, the movable rod 110 will be blocked by the limiting bead 23 again and deflected and then reset. At this time, the extension plate 112 will enter between the pair of clamping plates 111 again, and thus descend with the pair of clamping plates 111. By adjusting the height of the limiting bead 23, the movable range of the extension plate 112 can be adjusted accordingly, thereby adjusting the packaging quantity of the nanoemulsion.

[0026] like Figures 1 to 5 As shown, a bottom plate 3 is fixedly connected to the bottom of the side wall of the liquid storage tank 1; a servo motor 31 is fixedly connected to the top of the bottom plate 3; the output end of the servo motor 31 is arranged upward; a turntable 32 is fixedly connected to the output end of the servo motor 31; a plurality of placement grooves 33 are provided on the top of the turntable 32; a pair of springs 34 are fixedly connected to the middle of the placement grooves 33; the other end of the spring 34 is fixedly connected to a squeezing plate 35; when the nanoemulsion inside the liquid passage 13 is ejected through the second one-way valve 14 due to the downward pressure of the extension plate 112, an impact force will be generated, thereby easily The container is shaken by impact, so that the nanoemulsion is scattered and the amount is failed. By placing the container between a pair of squeezing plates 35, the container is clamped by the pair of squeezing plates 35, so that it is difficult to shake when the nanoemulsion is weighed. At the same time, the quantitative rotation of the servo motor 31 cooperates with the loading and unloading device to realize semi-automatic or fully automatic weighing of the device. Through the above structure, when the nanoemulsion is weighed, the shaking of the weighing container due to the impact of the nanoemulsion can be reduced, thereby reducing the occurrence of the nanoemulsion failing to fall into the container correctly.

[0027] like Figures 1 to 5As shown, a pair of slide grooves 4 are provided at the bottom of the placement groove 33; a slide bar 41 is fixedly connected to the bottom of the extrusion plate 35; the slide bar 41 is slidably connected to the inside of the slide groove 4; a support plate 42 is fixedly connected to the top of the bottom plate 3; the bottom end of the slide bar 41 is arranged lower than the top end of the support plate 42; when working, a pair of extrusion plates 35 located in the placement groove 33 below the second one-way valve 14 will clamp the container, and after the container is weighed, the rotation of the servo motor 31 drives the turntable 32 to rotate, and when moving, a pair of The sliding rods 41 will be affected by the ends of the support plates 42 and move away from each other, thus no longer clamping the container, so that the completed container can be more conveniently removed from the placement groove 33, and then a new container can be placed between a pair of extrusion plates 35. After the pair of extrusion plates 35 leave the top of the support plates 42 as the turntable 32 runs, the pair of extrusion plates 35 will clamp the container again. Through the above structure, the influence of the pair of extrusion plates 35 can be reduced when loading and unloading the component containers, thereby making the loading and unloading of the component containers more convenient.

[0028] like Figures 1 to 3 As shown, the top and bottom of the first slider 19 are fixed with elastic films 5; the other ends of a pair of elastic films 5 are respectively fixed to the top and bottom of the first bracket 17; an air hole 51 is opened in the middle of the elastic film 5; when the first slider 19 moves up and down along the bidirectional screw assembly 18, the pair of elastic films 5 will shrink or stretch accordingly, making it difficult for external impurities to fall on the surface of the bidirectional screw assembly 18, thereby reducing the occurrence of jamming when the first slider 19 moves.

[0029] like Figures 1 to 3 As shown, the middle part of the movable rod 110 is rotatably connected to the roller 6; the surface of the roller 6 is a colloid material; when working, the roller 6 will come into contact with the middle part of the limiting bead 23 during the up and down movement of the movable rod 110, thereby converting the sliding friction between the movable rod 110 and the limiting bead 23 into rolling friction, thereby reducing the wear between the movable rod 110 and the limiting bead 23, and further improving the service life of the device.

[0030] like Figure 5 As shown, the top of the support plate 42 is rotatably connected to a plurality of balls 7; the plurality of balls 7 are evenly distributed on the top of the support plate 42; through the above structure, most of the weight of the turntable 32 can be transmitted to the bottom plate 3 through the balls 7, thereby reducing the rotation load of the servo motor 31 and improving the service life of the device.

[0031] During operation, the operation of the bidirectional screw assembly 18 drives the first slider 19 to move up and down, thereby driving the extension plate 112 to move up and down through a pair of clamping plates 111. When the extension plate 112 moves up, the nanoemulsion inside the liquid storage tank 1 is drawn into the interior of the liquid passage pipe 13 through the first one-way valve 12. When the extension plate 112 moves down, the nanoemulsion inside the liquid passage pipe 13 is squeezed out through the second one-way valve 14. Since the moving path of the first slider 19 is fixed when the bidirectional screw assembly 18 is running, the rising and falling distances of the extension plate 112 are also fixed, so that the nanoemulsion entering the liquid passage pipe 13 and the nanoemulsion sprayed through the second one-way valve 14 are the same, thereby achieving The limiting bead 23 can be moved to different heights by rotating the adjusting screw 21. When the first slider 19 rises due to the operation of the two-way screw assembly 18, the middle part of the movable rod 110 is squeezed by the limiting bead 23 when passing through the limiting bead 23 and rotates, so that the pair of clamping plates 111 deviates from the top and bottom of the extension plate 112. After the first slider 19 is away from the limiting bead 23, the pair of clamping plates 111 are reset under the action of the torsion spring. When the first slider 19 turns around and descends due to the operation of the two-way screw assembly 18, the movable rod 110 is blocked by the limiting bead 23 again and deflected and then reset. At this time, the extension plate 112 enters between the pair of clamping plates 111 again, so that The pair of clamping plates 111 descends, and when the nanoemulsion inside the liquid passage 13 is ejected through the second one-way valve 14 due to the downward pressure of the extension plate 112, an impact force is generated, which is easy to impact and shake the component container, so that the nanoemulsion is scattered and the component fails. By placing the container between the pair of squeezing plates 35, the container is clamped by the pair of squeezing plates 35, so that it is difficult to shake when the nanoemulsion is being weighed. At the same time, the quantitative rotation of the servo motor 31 cooperates with the loading and unloading device to realize the semi-automatic or fully automatic component of the device. The pair of squeezing plates 35 located in the placement groove 33 below the second one-way valve 14 will clamp the container. After the container is weighed, the container is clamped by the pair of squeezing plates 35. The rotation of the servo motor 31 drives the turntable 32 to rotate. When moving, a pair of slide bars 41 under the container that has completed the weight will be affected by the end of the support plate 42 and move away from each other, so that the container will no longer be clamped, so that the container that has completed the weight can be more conveniently removed from the inside of the placement groove 33, and then a new container is placed between the pair of extrusion plates 35. After the pair of extrusion plates 35 leave the top of the support plate 42 as the turntable 32 runs, the pair of extrusion plates 35 will clamp the container again. When the first slider 19 moves up and down along the bidirectional screw assembly 18, the pair of elastic membranes 5 will shrink or stretch accordingly, making it difficult for external impurities to fall on the surface of the bidirectional screw assembly 18.

[0032] The above shows and describes the basic principles, main features and advantages of the utility model.
