Description

Technical Field

[0001] This utility model relates to the field of metering and filling technology, specifically to a precise weighing and feeding device. Background Technology

[0002] When producing some fruit juice beverages, purified water is required, and the amount of water added should be determined according to the net content of the juice. This is especially true for producing low-sugar fruit juices, where the amount of water added needs to be strictly controlled.

[0003] In related technologies, the most common method for quantitative water addition is using filling machines. After the container is placed under the filling machine, some small filling machines use a peristaltic pump to control the water output. The water outlet pipe of the filling machine is inserted into the container or suspended above the container and drains water. However, this method of quantitative water addition has drawbacks. Water may adhere to the machine walls, especially with outlet pipes having an inner diameter exceeding 10 mm. Even after draining stops, a few drops of water may still slowly drip from the outlet pipe, affecting the accuracy of the water added to the juice or beverage. There is also the problem of water dripping onto the equipment, which requires cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a precise weighing and feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precise weighing and feeding device, including a weighing conveyor, a feeding machine placed on the side of the weighing conveyor, and the feeding machine connected to several feeding pipes. The weighing conveyor can monitor the weight of the water output, so that the water output of the feeding machine can be precisely controlled.

[0006] The feeder is equipped with an adjustment frame, on which a support plate is slidably mounted. The feed pipe is connected to the support plate. The adjustment frame is used to change the spacing of the feed pipe. The spacing of the feed pipe can be changed for containers of different sizes, so that water can be delivered to various containers.

[0007] The lower end of the feeding pipe is equipped with a connector, which has several tapered tubes. The tapered tubes are equipped with elastic plates inside, and the elastic plates have a spreading hole in the middle of their surface. The elastic plates can block water, ensuring that no water drips when the feeding machine stops running.

[0008] Furthermore, the surface of the adjusting frame is provided with a sliding strip hole, and a bolt that passes through the sliding strip hole is inserted into the surface of the support plate. A nut is screwed onto the bolt. Loosening the nut allows the feed tube to move within the sliding strip hole, thereby realizing the movement adjustment of the feed tube and the support plate, and also allowing the position of the feed tube to be locked.

[0009] Furthermore, a cylindrical shell is screwed to the side of the support plate, and a spring is placed inside the cylindrical shell. The spring restricts the downward movement of the feeding tube. A top block is connected to the right end of the spring. The top block has a locking seat, which is engaged with the spring. The top block abuts against the surface of the feeding tube. Twisting the cylindrical shell can compress the spring, ensuring that the top block locks the feeding tube tightly and preventing the feeding tube from loosening.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) The feeding machine delivers water to the feeding pipe. The water pressure in the feeding pipe increases. The water pressure opens the elastic plate and is discharged through the cone tube, sending the water into the container. The weighing conveyor monitors the weight of the water in the container. When the specified weight is reached, the feeding machine stops delivering water. The water pressure in the feeding pipe decreases. The elastic plate closes to block the water from dripping down, avoiding the problem of water dripping from the cone tube. The water addition is more accurate and also eliminates the trouble of cleaning water droplets.

[0012] (2) The support plate can be loosened by turning the bolt. Moving the bolt in the sliding strip hole can move the support plate. The movement of the support plate will change the position of the feeding pipe, which is convenient to adjust the feeding pipe according to the position of the container. The feeding pipe can slide up and down, and the distance between the feeding pipe and the container can be controlled. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example:

[0020] Please see Figure 1-4 This utility model provides a technical solution: a precise weighing and feeding device, including a weighing conveyor 1, a feeding machine 3 placed on the side of the weighing conveyor 1, and the feeding machine 3 connected to a plurality of feeding pipes 5. The weighing conveyor 1 and the feeding machine 3 are linked together, and the weight weighed by the weighing conveyor 1 is sent to the feeding machine 3 to ensure that the feeding machine 3 can dispense water in a quantitative manner.

[0021] An adjusting frame 6 is installed on the surface of the feeding machine 3. A support plate 7 is slidably installed on the adjusting frame 6. The feeding pipe 5 is connected to the support plate 7. The adjusting frame 6 is used to change the spacing of the feeding pipe 5. When the container size is small, the spacing of the feeding pipe 5 can be reduced. When the container size is large, the spacing of the feeding pipe 5 can be increased. Different sized containers can be used.

[0022] The lower end of the feeding pipe 5 is equipped with a connector 16, which has several tapered tubes 9. The tapered tubes 9 can hold water and prevent water from dripping downwards, making the function of preventing water dripping from the tapered tubes 9 more stable. The tapered tubes 9 are provided with elastic plates 15 inside. The elastic plates 15 have an opening hole in the middle of their surface. When the water pressure opens the elastic plates 15, water can be drained smoothly. When the water pressure decreases, the elastic plates 15 close to block the water.

[0023] In this embodiment, as Figure 1 As shown, a flexible hose 4 is connected between the feeding machine 3 and the feeding pipe 5. The flexible hose 4 provides space for the up and down movement of the feeding pipe 5. The flexible hose 4 can be made of transparent material so that the water status can be observed.

[0024] In this embodiment, as Figure 2 As shown, the surface of the adjusting frame 6 is provided with a sliding strip hole 10, and a bolt 11 is inserted through the sliding strip hole 10 on the surface of the support plate 7. A nut is screwed onto the bolt 11. Tightening the nut can prevent the nut and bolt 11 from clamping the adjusting frame 6 and the support plate 7. Moving the bolt 11 in the sliding strip hole 10 can drive the support plate 7 to move, thereby changing the position of the feeding pipe 5 to facilitate its correspondence with the position of the container.

[0025] In this embodiment, as Figure 3 As shown, a cylindrical shell 8 is screwed to the side of the support plate 7. A spring 12 is placed inside the cylindrical shell 8. The spring 12 restricts the feeding tube 5 from sliding down. When the cylindrical shell 8 is turned, the spring 12 can be compressed or released. When the spring 12 presses against the feeding tube 5, the feeding tube 5 can be adjusted up and down, and the feeding tube 5 can also be prevented from sliding.

[0026] In this embodiment, as Figure 3As shown, the right end of the spring 12 is connected to a top block 13, and the top block 13 has a locking seat 14. The locking seat 14 is engaged with the spring 12. The top block 13 abuts against the surface of the feeding tube 5. The contact area between the top block 13 and the feeding tube 5 is large, ensuring that the feeding tube 5 will not slide.

[0027] In this embodiment, as Figure 3 As shown, the weighing conveyor 1 has a frame 2 for preventing it from falling off the surface edge. The frame 2 can prevent it from easily shifting off or falling off the weighing conveyor 1, which is beneficial for aligning the container with the feeding pipe 5.

[0028] Specifically, during use, the weighing conveyor 1 delivers the container to the bottom of the feeding pipe 5. The feeder 3 pumps water into the feeding pipe 5. When the water pressure in the feeding pipe 5 is greater than the elastic force of the elastic plate 15, the elastic plate 15 is opened by the water, and the water is delivered into the container through several cone pipes 9. At this time, the weighing conveyor 1 monitors the weight of the container. When the weight reaches the set threshold, the feeder 3 stops supplying water to the feeding pipe 5. When the water pressure in the feeding pipe 5 is less than the elastic force of the elastic plate 15, the elastic plate 15 closes, which can block the water in the feeding pipe 5 and prevent water from leaking out of the feeding pipe 5. When the feeder 3 stops supplying water, the cone pipes 9 immediately stop discharging water to ensure the accuracy of water addition and prevent dripping.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
