[0002] There are many types of canned fruits and vegetables on the market, such as canned bayberries, canned mangoes, or mixed fruit and vegetable canned products. These canned products are processed first. Because the processed fruit pulp is fully soaked, its specific gravity is relatively high, and it usually sinks to the bottom of the juice. Therefore, special attention needs to be paid to the uniformity of the fruit pulp during filling.
[0003] Existing quantitative filling equipment for fruits and vegetables uses flow valves or weighing for measurement. Flow valves have a large deviation in measuring fruit pulp, while weighing is inefficient. Therefore, it is necessary to improve the existing filling equipment so that it can quickly complete quantitative filling. Summary of the Invention

The feed hole 802 is located at the upper part of the guide cylinder 8, and the discharge hole 803 is located at the lower part of the guide cylinder 8. The discharge hole 803 and the feed hole 802 are staggered. A receiving hopper 9 is provided outside the discharge hole 803 on the guide cylinder 8. The receiving hopper 9 is connected to the filling pipe assembly, which includes a discharge pipe 10, a movable pipe 16, and a drive assembly C. The discharge pipe 10 is connected to the output end of the receiving hopper 9. The movable pipe 16 is sleeved on the discharge pipe 10 and is located directly above the filling station. When the packaging can is rotated to the filling station, the mouth of the packaging can is coaxial with the movable pipe 16. The drive assembly C includes, but is not limited to, a hydraulic cylinder B17. The body of the hydraulic cylinder B17 is connected to the bracket 7. The output end of the hydraulic cylinder B17 is connected to the movable pipe 16. When the hydraulic cylinder B17 is working, it drives the movable pipe 16 to slide along the axial direction of the discharge pipe 10 so that the lower end of the movable pipe 16 is inserted into the packaging can. The slider 11 is slidably disposed inside the guide cylinder 8. A metering hole 111 is provided on the slider 11. The inner diameter of the upper opening of the metering hole 111 is not less than the inner diameter of the feed hole 802, and the inner diameter of the lower opening of the metering hole 111 is not greater than the inner diameter of the discharge hole 803. The slider 11 is connected to a sliding cover 12, which slides in contact with the upper wall of the sliding channel 801. The drive assembly B includes, but is not limited to, a hydraulic cylinder A13. The body of the hydraulic cylinder A13 is connected to the guide cylinder 8, and the output end of the hydraulic cylinder A13 is connected to the slider 11. When the slider 11 is in a sliding state, the metering hole 111 alternately communicates with the feed hole 802 and the discharge hole 803. When the slider 11 is communicating with the discharge hole 803, the sliding cover 12 closes the feed hole 802.A positioning plate 14 is installed at each end of the slider 11 inside the guide cylinder 8. A set of pressure sensors 15 is installed at the adjacent ends of the two positioning plates 14. A controller electrically connected to the pressure sensors 15 is installed on the frame 1. The controller is electrically connected to the control switches of the motor A4, hydraulic cylinder A13, and hydraulic cylinder B17. The storage tank 18 is installed on the support 7. A discharge pipe 19 is installed at the bottom of the storage tank 18, and the discharge pipe 19 is connected to the inlet hole 802. A top cover is installed on the storage tank 18. An inlet pipe 20 communicating with the inside of the storage tank 18 is installed on the top cover. A stirring mechanism is installed inside the storage tank 18. The stirring mechanism includes a stirring shaft 21, a stirrer 22, and a drive assembly D. The stirring shaft 21 is located inside the storage tank 18 and is rotatably connected to the top cover. The stirrer 22 is coaxially connected to the stirring shaft 21. The stirrer includes several sets of support rods and spiral plates connected to each set of support rods. The multiple sets of spiral plates are distributed in a ring array around the stirring shaft 21. The drive component D includes, but is not limited to, motor B23. The body of motor B23 is connected to the top cover, and the output end of motor B23 is connected to the stirring shaft 21.
[0027] It should be noted that the motors in this embodiment are all servo motors, the controller is a PLC controller, and the input terminals of hydraulic cylinders A13 and B17 are connected to the output terminal of the external hydraulic pump.
[0028] In this embodiment, the raw materials to be filled are added to the storage tank 18. Since it is a canned fruit and vegetable product, there will be fruit pulp and juice. At this time, the motor B23 is started, and the motor B23 drives the stirring shaft 21 to rotate, thereby driving the stirrer 22 to rotate. The stirrer 22 is used to stir the raw materials in the storage tank 18 to keep the various fruit pulps evenly dispersed. Then, the hydraulic cylinder A13 is started, and the hydraulic cylinder A13 pulls back the slider 11, so that the metering hole 111 is connected to the feed hole 802. The fruit pulp and juice at the bottom of the storage tank 18 automatically enter the metering hole 111. The capacity of the metering hole 111 is exactly the standard filling volume of the packaging can. Since the slider 11 is in contact with the pressure sensor 15 on the right, the pressure signal is fed back to the controller. The controller controls the motor A4 to start and drive the turntable 3 to rotate one single... The angle of the position causes the limiting groove 301, which is next to hold the packaging can, to rotate to the filling station. Then, the hydraulic cylinder B17 starts and drives the movable tube 16 downward. The movable tube 16 is inserted into the packaging can. Then, the hydraulic cylinder A13 drives the slider 11 to move towards the discharge hole 803. The sliding cover 12 automatically keeps the feed hole 802 closed. When the metering hole 111 is connected to the discharge hole 803, the mixture in the metering hole 111 automatically enters the packaging can along the receiving hopper 9, the discharge pipe 10 and the movable tube 16. Since the slider 11 is in contact with the pressure sensor 15 on the left, the pressure signal is fed back to the controller. The controller controls the linear vibration motor 203 to start and perform high-frequency vibration on the bottom of the packaging can, so that the mixture is quickly spread evenly in the packaging can and prevents accumulation. This cycle is repeated.

Two sets of fixing frames 5 are symmetrically arranged about the axis of the limiting barrel 2 on the frame 1. A set of conveyor belts 6 is arranged on each of the two sets of fixing frames 5. The ends of the two sets of conveyor belts 6 that are close to each other are extended into the corresponding inlets and outlets 201. The two sets of conveyor belts 6 run in the same direction. The bearing surfaces of the two sets of conveyor belts 6 are flush with the bottom surface of the inner cavity of the limiting barrel 2.
[0031] In this embodiment, the conveyor belt 6 is a common structure and will not be described in detail. The empty packaging cans are conveyed at a constant speed into the limiting groove 301 on the left side of the turntable 3 by the left conveyor belt 6, while the packaging cans that have been filled in the limiting groove 301 on the right side of the turntable 3 automatically fall onto the right conveyor belt 6 and are sent away, thus realizing automatic loading and unloading.
