Description

Technical Field

[0001] The present invention belongs to the technical field of quantitative filling, and particularly relates to a syrup quantitative extractor. Background Art

[0002] Syrup is viscous and has poor fluidity, making it difficult to perform quantitative filling. Moreover, it is prone to drawing, which affects packaging and cleaning.

[0003] Precise filling involves metering methods such as volumetric, gravimetric, or flow meters; the gravimetric method may use load cells, but the viscosity of syrup may cause residue, thus affecting accuracy. Also, for high-efficiency assembly line work, a device for secondary feedback adjustment is generally not designed, and syrup is not allowed to drip completely for a long time. Volumetric methods are more common for viscous liquids, such as piston pumps or peristaltic pumps, but high-precision control is required. Flow meters may need to consider the viscosity of the fluid and require data feedback from Coriolis mass flow meters to achieve accurate measurement. Additionally, heating the syrup to improve its fluidity is also one of the commonly used methods. That is to say, in the prior art, quantitative filling of syrup can basically be achieved, but due to the drawing of syrup, it is still difficult to avoid in high-efficiency work, resulting in slightly poor accuracy due to incomplete dripping of syrup. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a syrup quantitative extractor, which improves the filling efficiency and reduces the long natural dripping time and drawing of syrup by changing the diameter of the filling port and the height of the filling port after filling.

[0005] To achieve the above object, the present invention provides the following technical solution: A syrup quantitative extractor includes a rigid filling tube, and an elastic tube head is fixedly connected to the filling port of the filling tube. A plurality of control plates fixed to its outer surface are arranged around the outer side of the elastic tube head.

[0006] The control plates control the opening and closing of the elastic tube head in a movable manner. When the control plates control the elastic tube head to close, the height of its end is higher than the height when the control plates control the elastic tube head to open.

[0007] Preferably, as a syrup quantitative extractor of the present invention, after the control plates control the elastic tube head to open to the maximum extent, the plurality of control plates enclose a cylindrical intermittent structure.

[0008] Preferably, as a syrup quantitative extractor of the present invention, when the elastic tube head is not stressed, its bottom is a conical structure.

[0009] Preferably, as a syrup quantitative extractor of the present invention, the fixed surface of the elastic tube head is fixedly connected to the inner wall surface of the control plate.

[0010] Preferably, as a syrup quantitative extractor of the present invention, during the process of the control board controlling the elastic tube head to open and then close, the ends of the control board first rotate towards each other and then move towards each other to close.

[0011] Preferably, as a syrup quantitative extractor of the present invention, an anti-sticking coating is applied to the outer surface of the bottom of the control board.

[0012] Preferably, as a syrup quantitative extractor of the present invention, a connecting piece is fixedly connected to the outer surface of the control board. One end of the connecting piece is rotatably connected to a fixed shaft inside, and the other end of the connecting piece is rotatably connected to a first rotating bracket through a rotating shaft. One end of the first rotating bracket is fixedly connected to one end of the telescopic mechanism.

[0013] Preferably, as a syrup quantitative extractor of the present invention, a through groove is provided at one end of the connecting piece, and the fixed shaft is arranged inside the through groove.

[0014] Preferably, as a syrup quantitative extractor of the present invention, a limiting block is fixedly connected to one end of the fixed shaft located in the through groove. After the control board rotates to the maximum limit in the closing direction, the limiting block contacts the surface of the through groove.

[0015] Preferably, as a syrup quantitative extractor of the present invention, the other end of the telescopic mechanism is fixedly connected to the mounting bracket through a second rotating bracket, and the fixed shaft is fixedly connected to the mounting bracket through a third rotating bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By changing the diameter of the filling port and simultaneously changing the height of the filling port after filling, the high efficiency of filling is achieved, and the situation of long natural dripping time and wire drawing of syrup is reduced. During the filling operation, the overall shape of the elastic tube head is approximately cylindrical, which will not reduce the filling speed when filling syrup. When it is necessary to stop filling, the diameter of the end of the elastic tube head is gradually reduced, so that the cross-sectional area of the syrup flow is reduced, the residual syrup amount is reduced, and the natural dripping time is shortened accordingly. At the same time, after the liquid becomes thinner, the cohesive force between syrup molecules is more easily broken, and the wire drawing phenomenon can be effectively reduced.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1-10 shown:

[0037] A syrup quantitative extractor, including a rigid filling tube 1, an elastic tube head 2 is fixedly connected to the filling port of the filling tube 1. The elastic tube head 2 can be made of silicone or rubber with good elasticity. A number of control plates 3 fixed to its outer surface are arranged around the outer side of the elastic tube head 2;

[0038] The control plate 3 controls the opening and closing of the elastic tube head 2 in a movable manner. When the control plate 3 controls the elastic tube head 2 to close, the height of its end is higher than the height when the control plate 3 controls the elastic tube head 2 to open.

[0039] In this embodiment, because the syrup is viscous, has poor fluidity, is difficult to quantitatively fill, and is prone to drawing, which affects packaging and cleaning;

[0040] Precise filling involves metering methods, such as volumetric, gravimetric or flow meters; the gravimetric method may use load cells, but the viscosity of the syrup may cause residue, thus affecting the accuracy. And for high-efficiency assembly line work, generally no device for secondary feedback adjustment is designed, nor will it wait for a long time for the syrup to completely drip; volumetric methods are more common for viscous liquids, such as piston pumps or peristaltic pumps, but high-precision control is required. Flow meters may need to consider the viscosity of the fluid and need to cooperate with the data feedback of Coriolis mass flow meters to achieve. At the same time, heating the syrup to improve its fluidity is also one of the commonly used methods at present. That is to say, in the prior art, the quantitative filling of syrup can basically be achieved, but because the drawing of syrup is still difficult to avoid in high-efficiency work, there is a situation where the accuracy is slightly poor due to the incomplete dripping of the syrup.

[0041] This solution improves the high efficiency of filling and reduces the long natural dripping time and drawing of syrup by changing the diameter of the filling port and the height of the filling port after filling. During the filling work, the elastic tube head 2 is generally cylindrical in shape and will not reduce the filling speed when filling the syrup. When it is necessary to stop filling, gradually reduce the end diameter of the elastic tube head 2, so as to reduce the cross-sectional area of the syrup flow, reduce the residual syrup volume, and shorten the natural dripping time. At the same time, after the liquid flow becomes thinner, the cohesive force between syrup molecules is more easily broken, which can effectively reduce the drawing phenomenon;

[0042] At the same time, as Figure 6 shown by the height comparison dotted line, during the process of gradually reducing the end diameter of the elastic tube head 2, since the height of the end of the elastic tube head 2 is higher when the control plate 3 controls it to close than when the control plate 3 controls it to open, during the process of the syrup liquid flow gradually becoming thinner, there is also an upward pulling effect, which is equivalent to directly breaking the drawn syrup, further reducing the generation of the drawing phenomenon.

[0043] In an alternative embodiment, after the control board 3 controls the elastic tube head 2 to open to the maximum extent, several control boards 3 enclose a cylindrical intermittent structure.

[0044] In this embodiment, as Figure 2 and Figure 3 shown, in order to achieve smooth filling during the filling operation, after the control board 3 controls the elastic tube head 2 to open to the maximum extent, several control boards 3 enclose a structure approximating a cylindrical shape, that is, the inner wall surfaces of several control boards 3 coincide with the outer surface of the same cylinder.

[0045] In an alternative embodiment, when the elastic tube head 2 is not stressed, its bottom is a conical structure.

[0046] In this embodiment, as Figure 5 shown, in the natural state where the elastic tube head 2 is not stressed, the bottom of the elastic tube head 2 is a conical structure, so that when the bottom of the elastic tube head 2 contracts, it is smoother, and the elastic tube head 2 is prevented from being squeezed by the gap between two adjacent control boards 3.

[0047] In an alternative embodiment, the fixing surface 31 of the elastic tube head 2 is fixedly connected to the inner wall surface of the control board 3.

[0048] In this embodiment, the fixing surface 31 of the elastic tube head 2 can be fixed to the inner wall surface of the control board 3 by adhesion. During the adhesion fixing process, the elastic tube head 2 can be first expanded into a cylindrical shape, and then the fixing surface 31 of the elastic tube head 2 is fixed to the inner wall surface of the control board 3 using glue.

[0049] In an alternative embodiment, during the process of the control board 3 controlling the elastic tube head 2 to open to close, the ends of the control board 3 first rotate towards each other and then move towards each other to close.

[0050] In this embodiment, during the process of the control board 3 controlling the elastic tube head 2 to open to close, the ends of the control board 3 first rotate towards each other, that is, several control boards 3 change from the state of enclosing a similar cylindrical shape to a conical state. After the transformation is completed, several control boards 3 then move towards each other to close. Since during the closing process of the control board 3, the overall volume of the elastic tube head 2 is continuously decreasing, the syrup inside the elastic tube head 2 will gradually be discharged, and there will be a certain pressure exerted by the syrup inside the elastic tube head 2 on the side wall of the elastic tube head 2, causing the part of the elastic tube head 2 that is not fixed to the control board 3 to bulge outwards. If several control boards 3 are directly rotated to close, there may be a situation where the gap between two adjacent control boards 3 clamps and squeezes the elastic tube head 2. The main reason is that if it can be closed by rotating the control board 3, as Figure 2Taking the direction shown as an example, the distance between two adjacent control plates 3 shows a situation where it is smaller at the top and larger at the bottom. Since the gap at the bottom is larger, the lower part of the elastic tube head 2 in this gap will bulge out more significantly. During the closing process, the control plate 3 may clamp the elastic tube head 2 like scissors. To avoid this situation, after the control plate 3 rotates and closes to the maximum stroke, it moves towards each other and closes. After the control plate 3 rotates and closes to the maximum stroke, there is still a certain gap between the adjacent control plates 3. At this time, the gap is parallel. And because the thickness of the elastic tube head 2 increases after contraction, the internal structure is more compact, and the shape retention is also relatively good. At the same time, this gap is smaller, and it is difficult for the elastic tube head 2 to protrude outwards. The liquid pressure inside the elastic tube head 2 is not sufficient to make the elastic tube head 2 in this gap bulge outwards, thereby avoiding clamping the elastic tube head 2. When the elastic tube head 2 is expanded into a cylindrical shape, a coating with a low coefficient of friction and relatively high hardness can be sprayed on its fixing surface 31, such as a polytetrafluoroethylene (PTFE) powder coating, a ceramic powder coating, a diamond-like (DLC) powder coating (i.e., an amorphous carbon coating). These coatings make the powder particles arrange more closely as the elastic tube head 2 contracts, forming a protection.

[0051] In an alternative embodiment, an anti-adhesion coating, such as a Teflon coating, is applied to the outer surface at the bottom of the control plate 3 to reduce the adhesion of syrup.

[0052] In an alternative embodiment, a connecting member 4 is fixedly connected to the outer surface of the control plate 3. One end inner side of the connecting member 4 is rotatably connected to a fixed shaft 5, and the other end inner side of the connecting member 4 is rotatably connected to a first rotating bracket 6 through a rotating shaft. One end of the first rotating bracket 6 is fixedly connected to one end of a telescopic mechanism 7. The telescopic mechanism 7 can be a linear electric screw rod, a linear cylinder, or a linear hydraulic cylinder.

[0053] In this embodiment, when the control plate 3 needs to rotate, the telescopic mechanism 7 drives the first rotating bracket 6, and then drives the connecting member 4 to rotate around the fixed shaft 5, so that the connecting member 4 drives the control plate 3 to rotate.

[0054] In an alternative embodiment, a through groove 8 is provided at one end of the connecting member 4, and the fixed shaft 5 is arranged inside the through groove 8.

[0055] In this embodiment, as Figure 7 and Figure 8Taking the directions shown as an example, at this time, the control panel 3 is in an inclined state, and the fixed shaft 5 is located on the left side of the through groove 8. When the control panel 3 rotates in the vertical direction, since the rotation of the control panel 3 needs to overcome the elastic force of the elastic tube head 2 to move, and the elastic force exerted by the elastic tube head 2 on the control panel 3 is mainly concentrated at the lower position of the control panel 3, while the connecting member 4 is arranged at the upper position of the control panel 3. When the rotating bracket one 6 pulls the connecting member 4 to the left by the contraction of the telescopic mechanism 7, it will first drive the connecting member 4 to move to the left until the fixed shaft 5 moves to the right side of the through groove 8 and cannot move any further and then stops. Then, when the rotating bracket one 6 continues to move to the left, it will drive the connecting member 4 to rotate around the fixed shaft 5, and finally realize the connecting member 4 driving the control panel 3 to rotate and open;

[0056] When the control panel 3 rotates from the open state (i.e., the vertical state) to the closed state (i.e., the inclined state), as Figure 9 and Figure 10 shown in the directions taken as an example, at this time, the traction force of the connecting member 4 to the left is below the through groove 8, that is, the rotating bracket one 6 pulls the connecting member 4 to the left, and the traction force received by the control panel 3 to the right is mainly located at the bottom of the control panel 3. That is to say, the rotating bracket one 6 is located between the fixed shaft 5 and the bottom of the control panel 3 where the traction force to the right is received. When the telescopic mechanism 7 gradually extends, the rotating bracket one 6 gradually moves to the right, and the elastic force of the elastic tube head 2 will gradually stretch and close the bottom of the control panel 3. When the control panel 3 rotates and tilts to the maximum angle, continuing to move the rotating bracket one 6 to the right will push the entire connecting member 4 to move to the right, and finally realize the connecting member 4 driving the control panel 3 to move to the right.

[0057] In an optional embodiment, one end of the fixed shaft 5 located in the through groove 8 is fixedly connected with a limit block 9. After the control panel 3 rotates to the maximum limit in the closing direction, the limit block 9 contacts the surface of the through groove 8.

[0058] In this embodiment, by setting the limit block 9, the maximum angle of rotation and inclination of the connecting member 4 can be limited, thereby limiting the maximum angle of inclination rotation of the control panel 3.

[0059] In an optional embodiment, the other end of the telescopic mechanism 7 is fixedly connected with the mounting frame 12 through the rotating bracket two 10, the fixed shaft 5 is fixedly connected with the mounting frame 12 through the rotating bracket three 11, and the mounting frame 12 is fixedly connected with the outer surface of the filling pipe 1 through the connecting plate, so as to realize the fixed positions of the rotating bracket two 10 and the rotating bracket three 11.

[0060] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
