Against this background, the importance of food quantitative filling machines as an important production equipment is becoming increasingly prominent.

[0003] A food quantitative filling machine is an automated device specifically used to accurately fill liquid or semi-solid foods (such as beverages, seasonings, sauces, etc.) into containers according to preset weights or volumes. When a traditional filling machine is in use, it is necessary to first input the material into a container for weighing and weigh the material. When the weight of the material reaches the specified requirement, the feeding is stopped and the material in the container is poured into structures such as packaging cans to complete the quantitative filling work. However, this filling method has poor continuity, requires repeated weighing and filling of the material, and during this process, the container for weighing cannot collect new material, resulting in low work efficiency.

Therefore, it should not be construed as a limitation to the present invention.

[0018] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. This embodiment is written in a progressive manner.

[0019] As Figures 1 to 8 shown, a food quantitative filling machine of the present invention includes a vertical column 1 and a plurality of receiving barrels 4 distributed around the circumferential outer wall of the column 1. The receiving barrels 4 are rotatably mounted on the column 1; A channel for feeding materials is opened at the top of the column 1. A discharge port 29 is opened on the outer wall of the column 1. The discharge port 29 is communicated with the channel. A sealing ring 2 is rotatably sleeved on the outer wall of the column 1. A plurality of notches are opened on the circumferential inner wall of the sealing ring 2. Adjacent two notches are close to each other. A plurality of guide pipes 3 are arranged on the outer wall of the sealing ring 2. The guide pipes 3 are communicated with the notches. A closed guide groove is opened on the circumferential outer wall of the column 1. The guide groove is composed of a first arc groove 8, a second arc groove 9 and two inclined grooves 10. The inclined grooves 10 are used to connect the first arc groove 8 and the second arc groove 9, and the first arc groove 8 is located above the second arc groove 9; The receiving barrel 4 has an opening facing downward. The top of the receiving barrel 4 is communicated with the guide pipe 3. A piston 5 for carrying materials is vertically slidably arranged in the receiving barrel 4. A support plate 6 is arranged at the bottom of the piston 5. A sliding column 7 is horizontally arranged on the support plate 6. The sliding column 7 is slidably mounted in the guide groove; Wherein, an elastic unit for providing an upward elastic force for the piston 5 is arranged at the bottom of each piston 5, and a discharging unit for discharging the materials in the receiving barrel 4 is arranged at the bottom of the column 1.

[0020] Specifically, the elastic unit is used to provide an upward elastic force for the piston 5, so as to provide support for the piston 5. When the material falls onto the piston 5, the piston 5 is allowed to move downward and squeeze the elastic unit. The channel on the column 1 is mainly used to convey the material. The sealing ring 2 confines the discharge port 29 in a closed space. Since the sealing ring 2 only rotates on the column 1, the sealing ring 2 can achieve a good sealing effect on the discharge port 29, avoiding the random scattering or leakage of the material. The adjacent two notches on the inner circumferential wall of the sealing ring 2 approach each other. In this way, when one notch deviates from the discharge port 29, the other notch can be aligned with and communicate with the discharge port 29 in time. The notches are not shown in the drawings. The receiving barrel 4 is used to receive the material and weigh the material by using the elastic unit. When the material in the receiving barrel 4 increases, the material will squeeze the piston 5 to move downward, and the piston 5 squeezes the elastic unit. The support plate 6, the sliding column 7 and the guiding groove mainly guide the movement of the receiving barrel 4. The first arc groove 8 and the second arc groove 9 in the guiding groove are both horizontal.

[0021] During use, one notch on the sealing ring 2 is located at the position of the discharge port 29, and the sliding column 7 on the receiving barrel 4 corresponding to this notch is located in an inclined chute 10 that slopes downward. The material passes through the channel on the column 1 and the discharge port 29 and enters one notch. The material in the notch will enter a receiving barrel 4 through the guide pipe 3. At this time, the material in the receiving barrel 4 falls onto the piston 5. As the material continues to increase, the piston 5 gradually moves downward and squeezes the elastic unit. The piston 5 will drive the support plate 6 and the sliding column 7 to move downward synchronously. The sliding column 7 slides downward in the chute 10. Due to the guiding effect of the chute 10, the sliding column 7 generates a displacement in the circumferential direction of the column 1. The sliding column 7 will drive the receiving barrel 4 to move around the column 1 in the circumferential direction through the support plate 6 and the piston 5. The receiving barrel 4 drives the sealing ring 2 to rotate synchronously on the column 1 through the guide pipe 3, thereby enabling multiple receiving barrels 4 to move synchronously. Of course, multiple receiving barrels 4 can be in contact with each other here, so that multiple receiving barrels 4 rotate synchronously. When the sliding column 7 moves into the second arc groove 9, the notch corresponding to this sliding column 7 deviates from the discharge port 29, and the next notch moves to the position of the discharge port 29 and receives the material, and the sliding column 7 corresponding to the next notch moves into the chute 10, thereby enabling the corresponding receiving barrel 4 to receive the material. This receiving barrel 4 repeats the actions of the previous receiving barrel 4 in the same way, thereby achieving the working effect that multiple receiving barrels 4 receive the material one by one and continuously rotate on the column 1. When the receiving barrel 4 corresponding to the sliding column 7 in the second arc groove 9 moves to the position of the discharging unit, the material in the receiving barrel 4 is poured into the filling container on the external conveyor belt through the discharging unit, thereby achieving the quantitative filling work.

[0022] With the continuous movement of multiple receiving barrels 4, the continuous quantitative filling of the material can be achieved.

[0023] During actual use, since some materials will adhere to the inner wall of the receiving barrel 4, the upper surface of the piston 5, the inner wall of the material guiding pipe 3 and other positions, when weighing, the influence of this part of the material needs to be considered. Of course, the value of the specified quantity can also be increased by a certain amount, so that the amount of the filled material reaches or is slightly greater than the specified requirement, avoiding the phenomenon of short weight.

[0024] By using the method of automatically weighing the receiving barrel 4 and the method of automatically rotating the receiving barrel 4 by the weight of the material, the continuous automatic weighing work of multiple receiving barrels 4 can be realized. When the receiving barrel 4 carrying the material moves to the position of the discharging unit, the discharging unit will fill the material in the receiving barrel 4 into the external filling container, thereby realizing a continuous quantitative filling working method, improving the continuity and efficiency of production, and the equipment only needs to use the weight of the material to realize automatic operation, and its operation is simpler, convenient to use and popularize.

[0025] Further, the elastic unit includes a support ring 11 rotatably sleeved on the column 1. A telescopic rod 12 and a spring 13 are arranged between the support ring 11 and each piston 5. The spring 13 is sleeved outside the telescopic rod 12. One end of the telescopic rod 12 and one end of the spring 13 are both connected to the bottom of the piston 5, and the other end of the telescopic rod 12 and the other end of the spring 13 are both connected to the support ring 11.

[0026] Specifically, the telescopic rod 12 and the spring 13 are vertical, and the support ring 11 is located below the receiving barrel 4. When the receiving barrel 4 rotates, it will drive the support ring 11 to move synchronously. When the piston 5 moves downward in the receiving barrel 4, the piston 5 will compress the spring 13 and the telescopic rod 12, thereby using the spring 13 to provide an upward elastic thrust for the piston 5, and the telescopic rod 12 mainly provides support for the spring 13.

[0027] Further, when the sliding column 7 moves downward in one inclined groove 10, there will be a sliding column 7 moving upward synchronously in the other inclined groove 10, and at least one sliding column 7 exists in the inclined groove 10.

[0028] Specifically, two sliding columns 7 will exist in the two inclined grooves 10 at the same time, and the two sliding columns 7 will move in the opposite direction synchronously, so that multiple sliding columns 7 can move circularly in the guiding groove, and it is convenient for the elastic structure on the upward moving sliding column 7 to only affect the elastic structure on one downward moving sliding column 7 and the amount of the material carried on the piston 5, so that it is convenient to accurately calculate the weighing error caused by this influence, so as to facilitate calculating this error in the material weighing work. Of course, for different materials or different specifications of filling machines, the first experimental filling needs to be carried out to complete the calibration work.

[0029] In order to enable the materials falling into the receiving bucket 4 to smoothly push the receiving bucket 4 to move in the circumferential direction of the column 1, it is necessary to have at least one sliding column 7 in the chute 10, so that the continuous movement of the equipment can be achieved.

[0030] Furthermore, the discharge unit includes a support ring 18 sleeved on the outside of the column 1 and a filling tube 19 arranged on the lower side of the support ring 18, a swivel 16 is coaxially rotatably arranged on the support ring 18, the swivel 16 is fixedly connected to each receiving barrel 4 through a connecting plate 17, a plurality of fixed tubes 15 are arranged on the swivel 16, the support ring 18 blocks the fixed tubes 15, the upper input end of the fixed tube 15 is vertical, and a movable tube 14 is slidably inserted into the input end of the fixed tube 15, the movable tube 14 is fixed on the piston 5 and is connected to the inside of the receiving barrel 4.

[0031] In detail, the filling tube 19 corresponds to the position of the second arc groove 9 on the guide groove, and the supporting ring 18 can be fixed by an external bracket. When the receiving barrel 4 rotates, it will drive the connecting plate 17, the swivel 16, the fixed tube 15 and the movable tube 14 to move synchronously. When the fixed tube 15 moves to the position of the filling tube 19, the material in the receiving barrel 4 will be discharged downward through the movable tube 14, the fixed tube 15 and the filling tube 19 and poured into the external filling container. When the fixed tube 15 deviates from the filling tube 19, the supporting ring 18 blocks the fixed tube 15, so that the material in the receiving barrel 4 cannot flow out. Since the piston 5 needs to move in the vertical direction, the piston 5 can drive the movable tube 14 to slide on the fixed tube 15, and the movable tube 14 and the fixed tube 15 remain in a connected state.

[0032] Furthermore, a vertical cylinder 20 is provided at the bottom of the support ring 18, and the internal space of the vertical cylinder 20 extends upward to the upper surface of the support ring 18. A partition 21 is vertically slidably provided in the vertical cylinder 20. The partition 21 is connected to the inner wall of the vertical cylinder 20 by a spring piece 22. The filling tube 19 is fixed at the bottom of the partition 21, and the top of the filling tube 19 extends to the upper surface of the partition 21.

[0033] In detail, when the fixed tube 15 moves to the position of the vertical cylinder 20, the material in the receiving barrel 4 will flow into the partition 21 in the vertical cylinder 20. Due to the weight of the material, the partition 21 will move downward and compress the spring piece 22. The partition 21 carries the filling tube 19 and moves downward synchronously, and the filling tube 19 is inserted downward into the external filling container, thereby achieving accurate filling. As the material on the partition 21 gradually decreases, the spring piece 22 pushes the partition 21 in the reverse direction to reset and carry the filling tube 19 out of the external filling container, thereby realizing the insertion filling of the filling tube 19 while avoiding the filling tube 19 affecting the normal conveying work of the filling container.

[0034] Further, an adjusting ring 23 is slidably sleeved on the outer circumferential wall of the upright column 1, and a support ring 11 is rotatably sleeved on the outer wall of the adjusting ring 23. A plurality of vertical sliding grooves are formed on the outer wall of the upright column 1. Protrusions are provided on the adjusting ring 23, and the protrusions are slidably installed in the sliding grooves. A threaded rod 24 is rotatably arranged in the sliding groove. The threaded rod 24 passes through the protrusion and is threadedly connected therewith. The threaded rod 24 is locked to the upright column 1 by bolts.

[0035] Specifically, when it is necessary to change the material quantitative value, the vertical height of the adjusting ring 23 on the upright column 1 can be adjusted by rotating the threaded rod 24. At this time, the support ring 11 moves synchronously with the adjusting ring 23, so that the elastic force of the spring 13 can be conveniently adjusted.

[0036] Further, the bottom of the inner channel of the upright column 1 is provided as a slope 25, and the discharge port 29 is located at the lowest point of the slope 25.

[0037] Specifically, by providing the slope 25, the material in the channel can flow smoothly through the discharge port 29, avoiding the deposition of the material in the channel.

[0038] Further, a square hole is formed at the top of the receiving barrel 4. A sliding rod 26 is slidably inserted into the square hole. An air passage 27 is formed on the side wall of the sliding rod 26. Sealing blocks 28 are provided at both the upper and lower ends of the sliding rod 26, and the sealing blocks 28 can float on the surface of the material.

[0039] Specifically, when the material is introduced into the receiving barrel 4, the air in the receiving barrel 4 can be discharged through the air passage 27 on the sliding rod 26, thus avoiding the influence of air pressure on the material introduction work in the receiving barrel 4. When the liquid level of the material in the receiving barrel 4 rises to the position of the sealing block 28 at the bottom of the sliding rod 26, the sealing block 28 will float on the surface of the material. As the material increases, the sealing block 28 moves to the bottom of the square hole and plugs it, thus preventing the overflow and waste of the material in the receiving barrel 4. Of course, due to different materials of the material, the sealing block 28 can be made of different materials, or a coating can be applied on the surface of the sealing block 28 to achieve its floating effect.

[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
