Description

Technical Field

[0001] This utility model belongs to the field of liquid milk weighing technology, specifically a liquid milk filling and weighing system. Background Technology

[0002] Liquid milk is fresh milk from healthy cows that has been processed through effective heating and sterilization before being packaged and sold as drinking milk. According to the International Dairy Federation, liquid milk (liquid milk) is a general term for three types of dairy products: pasteurized milk, sterilized milk, and yogurt. Its chemical composition is complex, containing at least 100 different substances, primarily water, fat, phospholipids, proteins, lactose, and inorganic salts.

[0003] Liquid milk is sold in two main ways: packaged and unpackaged. Packaged sales involve selling a fixed quantity of liquid milk, while unpackaged sales involve weighing and measuring liquid milk according to demand.

[0004] When selling in bulk, the bottles need to be placed on an electronic scale, the valve opened, and the weight weighed using the scale. The existing valve dispenses milk quickly, which can easily lead to excessive milk discharge. Pouring the excess milk back out is not only prone to contamination but also inefficient. Adjusting the valve to a smaller size results in a slower milk discharge, which makes it easier to control the amount of milk dispensed more precisely, but it also affects the filling efficiency. Utility Model Content

[0005] This invention provides a liquid milk filling and weighing system to address the deficiencies in the prior art.

[0006] This utility model is achieved through the following technical solution:

[0007] A liquid milk filling and weighing system includes a base plate fixedly mounted on a support. A horizontal tube parallel to the base plate and closed at both ends is fixedly mounted above the base plate. The horizontal tube is connected to a milk inlet pipe at the top and to several quantitative milk outlet pipes and a vertical tube at the bottom. The quantitative milk outlet pipes are equipped with quantitative valves of different specifications. The vertical tube is equipped with a manual valve. An electronic scale is mounted on the base plate and is located directly below the vertical tube.

[0008] When using this application, if the customer's required milk volume in liters matches the corresponding dispensing valve's output volume, simply place the bottle under the corresponding dispensing tube to dispense the required amount of milk. If the required volume does not match the dispensing valve's output volume, first place the bottle under the dispensing valve that is closest to but smaller than the required volume, dispense the required amount of milk, then move the bottle to the electronic scale, and then rotate the manual valve to dispense the required amount of milk according to the electronic scale's data.

[0009] Preferably, the electronic scale includes a weighing surface. A strip-shaped groove is formed on the top surface of the weighing surface along its length. Two sliders are symmetrically arranged around the center of the weighing surface within the strip-shaped groove. The sliders are driven synchronously and in opposite directions by symmetrically arranged driving devices. A clamping plate is fixedly connected to the top surface of each slider. After a baby bottle is placed on the weighing surface of the electronic scale, the sliders move synchronously and in opposite directions using the driving devices, allowing the sliders to clamp the baby bottle and ensuring that the bottle opening is directly aligned with the vertical tube, achieving better filling and accommodating baby bottles of different widths.

[0010] Preferably, the driving device includes two lead screws with opposite rotation directions. The two ends of a strip-shaped groove penetrate the weighing surface. A fixing block is fixedly connected to the center of the strip-shaped groove. The fixing block has a transversely formed circular hole. A circular rod is rotatably connected to the circular hole via a bearing. The opposite ends of the circular rod are coaxially and fixedly connected to the corresponding lead screw. The slider has a threaded hole that mates with the lead screw. The opposite ends of the lead screw have an inner cross-shaped groove. When changing to different sizes of baby bottles, the inner cross-shaped groove of the lead screw is rotated with a screwdriver. The lead screw rotates, and because the lead screw is rotatably connected to the circular hole via the circular rod, and the circular hole is located on the fixing block, the fixing block cannot move. Therefore, the rotation of the lead screw drives the slider to move along the strip-shaped groove. Since the two lead screws rotate in opposite directions, the slider moves synchronously in opposite directions.

[0011] Preferably, the base plate has a through groove, within which a movable plate is installed. The electronic scale is fixedly mounted on the movable plate, and a horizontal plate is fixedly mounted on the frame. One end of an electric telescopic rod is fixedly connected to the top surface of the horizontal plate, and the other end of the electric telescopic rod is fixedly connected to the movable plate. The extension and retraction of the electric telescopic rod can raise or lower the movable plate, thereby raising or lowering the electronic scale. This, in turn, moves the bottle openings on the electronic scale up and down, allowing for better alignment with the vertical tube, preventing milk from spilling out of the bottle, and accommodating bottles of different heights.

[0012] Preferably, the lower part of the movable plate is a truncated cone that is wider at the top and narrower at the bottom. The center of the bottom surface of the truncated cone is perpendicular to and fixedly connected to the electric telescopic rod. The truncated cone structure of the lower part of the movable plate can achieve better support of the electric telescopic rod for the movable rod and minimize the left and right displacement of the movable plate.

[0013] Preferably, the horizontal plate and the support are fixedly connected by reinforcing ribs, and one end of a supporting vertical rod is vertically connected to the top surface of the horizontal plate, while the other end of the supporting vertical rod is fixedly connected to the base plate. The reinforcing ribs and the supporting vertical rod can respectively enhance the stability of the connection between the horizontal plate and the base plate.

[0014] The beneficial effects of this utility model are as follows: When the number of liters of milk required by the customer is the same as the quantitative output of the corresponding metering valve, the corresponding quantitative milk can be dispensed simply by placing the bottle under the corresponding quantitative milk outlet tube. When the required number of liters and the metering valve do not match, the required amount of milk can be dispensed first, and then the remaining amount of milk can be slowly dispensed. This not only ensures the accuracy of the milk output, but also improves the milk dispensing efficiency. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] A liquid milk filling and weighing system, such as Figure 1 and Figure 2As shown, the system includes a base plate 2 fixedly mounted on a support 1. A vertical plate is fixedly connected to the top of the base plate 2, facing downwards. A horizontal pipe 3, parallel to the base plate 2 and closed at both ends, is fixedly mounted on the upper part of the vertical plate via a cantilever beam. The horizontal pipe 3 is connected upwards to a milk inlet pipe and downwards to several metering milk outlet pipes 4 and a vertical pipe 5. The metering milk outlet pipes 4 are equipped with metering valves of different specifications, and the vertical pipe 5 is equipped with a manual valve. An electronic scale 6 is mounted on the base plate 2, located directly below the vertical pipe 5. The metering valves can be set to commonly used 1L, 2L, and 3L sizes, while the flow rate of the vertical pipe 5 is lower than that of the metering milk outlet pipes 4, achieving more precise control.

[0022] In use, milk is fed from the milk tank into the horizontal tube 3 via the milk inlet tube and sealed by the metering valve and the manual valve. If the customer's required milk volume in liters matches the corresponding metering valve's output, the bottle can be placed under the corresponding metering outlet tube 4 to dispense the corresponding amount of milk. If the required volume does not match the metering valve, the bottle should be placed under the metering valve closest to the required volume, and the milk should be dispensed. Then, the bottle should be moved to the electronic scale 6, and the manual valve should be rotated to dispense the required amount of milk according to the data from the electronic scale 6.

[0023] The electronic scale 6 includes a weighing surface. A strip-shaped groove 7 is formed along the length of the top surface of the weighing surface. Two sliders 8 are symmetrically arranged at the center of the weighing surface within the strip-shaped groove 7. The sliders 8 are driven synchronously and move in opposite directions by symmetrically arranged driving devices. A retaining plate 10 is fixedly connected to the top surface of each slider 8. The driving device includes lead screws 9 with opposite rotation directions. Both ends of the strip-shaped groove 7 penetrate the weighing surface. A fixing block is fixedly connected to the center of the strip-shaped groove 7. The fixing block has a horizontally formed circular hole. A circular rod is rotatably connected to the circular hole via a bearing. The opposite ends of the circular rod are coaxially and fixedly connected to the corresponding lead screw 9. A threaded hole is formed on the slider 8 to engage with the lead screw 9. An internal cross-shaped pattern is formed on the opposite ends of the lead screw 9.

[0024] When changing to different sizes of baby bottles, place the bottle on the scale 6 and use a screwdriver to rotate the inner crosshair of the lead screw 9. As the lead screw 9 rotates, it is connected to the round hole through the round rod. The round hole is set on the fixed block, which cannot move. Therefore, the rotation of the lead screw 9 drives the slider 8 to move along the strip groove 7. Since the two lead screws 9 rotate in opposite directions, the slider 8 moves synchronously in opposite directions. The movement of the slider 8 drives the clamping plate 10 to move, so that the clamping plate 10 can clamp the baby bottle and ensure that the bottle mouth is directly aligned with the vertical tube 5, achieving better filling and accommodating baby bottles of different widths.

[0025] The base plate 2 has a through groove, within which a movable plate 11 is installed. The electronic scale 6 is fixedly mounted on the movable plate 11. A horizontal plate 13 is fixedly mounted on the frame, and one end of an electric telescopic rod 12 is fixedly connected to the top surface of the horizontal plate 13. The other end of the electric telescopic rod 12 is fixedly connected to the movable plate 11. The extension and retraction of the electric telescopic rod 12 can raise or lower the movable plate 11, thereby raising or lowering the electronic scale 6. This, in turn, moves the bottle openings on the electronic scale 6 up and down, allowing for better alignment with the vertical tube 5, preventing milk from spilling out of the bottle opening, and accommodating bottles of different heights.

[0026] The lower part of the movable plate 11 is a truncated cone that is wider at the top and narrower at the bottom. The center of the bottom surface of the truncated cone is perpendicular to and fixedly connected to the electric telescopic rod 12. The truncated cone structure of the lower part of the movable plate 11 can better support the movable rod on the electric telescopic rod 12 and minimize the left and right displacement of the movable plate 11.

[0027] The horizontal plate 13 is fixedly connected to the bracket 1 by a reinforcing rib 14. One end of a supporting vertical rod is vertically connected to the top surface of the horizontal plate 13, and the other end of the supporting vertical rod is fixedly connected to the base plate 2. The reinforcing rib 14 and the supporting vertical rod can respectively enhance the stability of the connection between the horizontal plate 13 and the base plate 2.

[0028] The use of this application enables that when the required milk volume in liters and the corresponding metering valve output volume are the same, simply placing the bottle in the corresponding metering tube 4 times will dispense the corresponding amount of milk. When the required volume in liters and the metering valve do not match, the required amount of milk can be dispensed first, and then the remaining amount of milk can be slowly dispensed. This not only ensures the accuracy of the milk output but also improves the efficiency of milk dispensing.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
