Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to a multi-station filling device. Background Technology

[0002] To meet the demands of the modern market, many manufacturers have produced various types of filling machines. The use of rubber granule filling machines not only yields ideal overall results but also offers very high filling efficiency, providing greater assistance to modern manufacturers.

[0003] Currently, filling machines are required in the rice processing and production process.

[0004] A search revealed that Chinese patent CN222005586U discloses a multi-station rice filling device. The device uses an electric telescopic rod fixed to the inner wall of a positioning frame to move a lifting frame, which in turn moves a connecting pipe. This allows the rice inside the feeding hopper to be stably transported through the connecting pipe to the corresponding filling rack, enabling multi-station filling and facilitating simultaneous operation and filling at multiple stations, thus increasing the filling efficiency of the rice filling equipment.

[0005] However, the aforementioned device has the following drawbacks: the equipment achieves filling through the path of "feeding bucket → connecting pipe → dispensing rack," but it does not mention any metering devices (such as weighing sensors, flow control valves, or metering cups). Relying solely on the gravity feeding of the feeding bucket and the electric telescopic rod to control the raising and lowering of the connecting pipe for start and stop, it is impossible to accurately control the filling volume at each station. In actual production, due to the uneven size of rice grains and fluctuations in feeding speed (such as pressure differences caused by changes in the remaining amount in the feeding bucket), the filling volume at each station is prone to deviation, making it difficult to meet the precise quantitative requirements of different packaging sizes (such as 5kg and 10kg). Therefore, further improvement is needed. To this end, we propose a multi-station filling device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-station filling device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station filling device, including a material barrel and a controller, wherein a bearing seat is fixedly sleeved on the outer surface of the material barrel, a connecting pipe is fixedly connected to the inner ring of the bearing housing, and the connecting pipe is rotatably sleeved on the outer surface of the material barrel, a rubber ring is fixedly connected to the bottom of the connecting pipe, a bottom chamber is fixedly fixed to the bottom of the rubber ring, an elastic support is connected between the connecting pipe and the bottom chamber, and a rotating component is installed together with the bearing seat body of the elastic support;

[0008] A vibration motor is fixedly installed at the bottom of the compartment;

[0009] The bottom of the silo is fixedly connected to several hoppers, the bottom of each of the several hoppers is fixedly connected to an electric butterfly valve, the discharge end of each of the several electric butterfly valves is fixedly connected to a temporary storage cylinder, and the elastic bracket is fixed to the several temporary storage cylinders.

[0010] Each of the aforementioned temporary storage cylinders has a weighing component sealed and attached to its bottom, and each of the aforementioned weighing components is equipped with a deflection component together with the elastic support.

[0011] Furthermore, three support frames are evenly fixedly connected to the outer wall of the bearing housing, and the controller is fixedly installed on the outer wall of the adjacent support frame, which not only provides stable support for the whole equipment, but also facilitates the installation and wiring of the controller.

[0012] Furthermore, the elastic support includes two rubber sleeves, which are respectively fixedly fitted onto the outer surface of the bottom compartment and the connecting pipe. A reinforcing frame is fixedly connected between the two rubber sleeves, and the reinforcing frame is fixedly connected to the temporary storage cylinder. The rubber sleeves can buffer vibration and rotational impact, while the reinforcing frame enhances the overall structural rigidity.

[0013] Furthermore, the rotating assembly includes a first motor, which is fixedly mounted on the outer wall of the bearing housing. The drive end of the first motor is fixedly connected to a drive gear, and the outer surface of the drive gear is meshed with a driven gear. The driven gear is fixedly sleeved on the outer surface of the reinforcing frame, which can drive the temporary storage cylinder to accurately switch work positions.

[0014] Furthermore, each of the aforementioned deflection components includes a second motor, which is fixedly mounted on the top of the reinforcing frame. The drive end of the second motor is fixedly connected to a rotating shaft, which passes through the reinforcing frame and is rotatably connected to it. The bottom of the rotating shaft is fixedly connected to a mounting base, which can drive the tray to deflect, thereby achieving the sealing and opening of the temporary storage cylinder and ensuring smooth switching between weighing and unloading.

[0015] Furthermore, several of the weighing components include a weighing sensor, which is fixedly embedded in the top of the mounting base. The detection end of the weighing sensor is fixedly connected to a tray, and the tray is sealed and fitted to the bottom of the temporary storage cylinder. This not only enables real-time and accurate detection of material weight, but also seals the temporary storage cylinder through the tray.

[0016] The beneficial effects of this utility model are:

[0017] In use, this invention uses a weighing component to detect the weight of the material in the storage cylinder in real time, and a controller to accurately control the opening and closing of the electric butterfly valve, thus solving the problem of filling volume deviation caused by the lack of a metering device in existing equipment. At the same time, the rotating component allows the storage cylinder to alternate between the feeding and weighing position and the unloading position, and the vibration motor promotes the flow of materials, ensuring synchronous and efficient operation of multiple stations, meeting the accurate quantitative requirements of different packaging specifications, and improving filling accuracy and efficiency.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-4As shown, a multi-station filling device is disclosed, including a material tank 1 and a controller 10. A bearing seat 14 is fixedly sleeved on the outer surface of the material tank 1. Three support frames 12 are evenly fixedly connected to the outer wall of the bearing seat 14, and the controller 10 is fixedly installed on the outer wall of the adjacent support frame 12.

[0027] The bearing housing 14 has a bearing inner ring fixedly connected to a connecting pipe 15, and the connecting pipe 15 is sealed and rotatably sleeved on the outer surface of the material bucket 1. A rubber ring 16 is fixedly connected to the bottom of the connecting pipe 15, and a bottom chamber 18 is fixedly connected to the bottom of the rubber ring 16. An elastic support is connected between the connecting pipe 15 and the bottom chamber 18. The elastic support includes two rubber sleeves 17. The rubber sleeves 17 are made of nitrile rubber, which can effectively buffer the vibration and rotational impact during equipment operation. The two rubber sleeves 17 are fixedly sleeved on the outer surfaces of the bottom chamber 18 and the connecting pipe 15, respectively. A reinforcing frame 7 is fixedly connected between the two rubber sleeves 17.

[0028] The elastic bracket and the bearing housing 14 are mounted together with a rotating assembly. The rotating assembly includes a first motor 2, which is fixedly mounted on the outer wall of the bearing housing 14. The drive end of the first motor 2 is fixedly connected to a drive gear 3. The outer surface of the drive gear 3 is meshed with a driven gear 4, which is fixedly sleeved on the outer surface of the reinforcing frame 7. The first motor 2 is a servo motor, model Mitsubishi HC-KFS43.

[0029] A vibration motor 6 is fixedly installed at the bottom of the bottom compartment 18. The vibration motor 6 is a three-phase asynchronous vibration motor with the model number YZU-5-2.

[0030] The bottom of the silo 18 is fixedly connected to several hoppers 5, and the bottom of each of the hoppers 5 is fixedly connected to an electric butterfly valve 11. The discharge end of each of the electric butterfly valves 11 is fixedly connected to a temporary storage cylinder 9, and the reinforcing frame 7 is fixedly connected to the temporary storage cylinder 9. The electric butterfly valve 11 is a sanitary electric butterfly valve with the model number D971X-16P.

[0031] Several temporary storage cylinders 9 have weighing components sealed and attached to their bottoms. Several weighing components are mounted with deflection components together with elastic supports. Several deflection components include a second motor 13. The second motor 13 is a stepper motor, model Xinje DS2-20P7, and is fixedly mounted on the top of the reinforcing frame 7. The drive end of the second motor 13 is fixedly connected to a rotating shaft 19, which passes through the reinforcing frame 7 and is rotatably connected to it. The bottom of the rotating shaft 19 is fixedly connected to a mounting base 8. Several weighing components include a weighing sensor 21, which is fixedly embedded in the top of the mounting base 8. The detection end of the weighing sensor 21 is fixedly connected to a tray 20, which is sealed and attached to the bottom of the temporary storage cylinder 9. The weighing sensor 21 is a strain gauge type weighing sensor, model Mettler Toledo MT1260.

[0032] The controller 10 is a Siemens S7-1200 PLC controller, which is electrically connected to the first motor 2, the second motor 13, the electric butterfly valve 11, and the weighing sensor 21, which is conducive to controlling the overall operation.

[0033] Working principle: After the equipment is started, the material in the material bucket 1 flows into the bottom hopper 18 through the connecting pipe 15. The bearing built into the bearing seat 14 ensures that the connecting pipe 15 can rotate flexibly with the elastic support. At this time, the rotating component starts to work: the first motor 2 drives the drive gear 3 to rotate, and through the meshing transmission with the driven gear 4, it drives the reinforcing frame 7 and the bottom hopper 18 and temporary storage cylinder 9 fixed on it to rotate as a whole, so that several temporary storage cylinders 9 alternately occupy the "loading and weighing position" and the "unloading position", forming a circular circulation station.

[0034] When the temporary storage cylinder 9 rotates to the "feeding and weighing position," its bottom seals against the tray 20 of the weighing assembly. Simultaneously, the controller 10 opens the electric butterfly valve 11 at the bottom of the corresponding hopper 5. Under the high-frequency vibration of the vibrating motor 6, the material in the bottom hopper 18 quickly falls into the temporary storage cylinder 9 along the hopper 5. At the same time, the weighing sensor 21 detects the weight of the material in the temporary storage cylinder 9 in real time and feeds the data back to the controller 10. When the preset weight is reached, the controller 10 immediately closes the electric butterfly valve 11, completing the precise quantitative weighing.

[0035] Meanwhile, the bottom tray 20 of the temporary storage cylinder 9, which is in the "unloading position", is separated from the temporary storage cylinder 9 by the deflection component: the second motor 13 drives the rotating shaft 19 to rotate, causing the mounting base 8 and the tray 20 to deflect at a certain angle, so that the bottom opening of the temporary storage cylinder 9 is exposed, and the weighed material inside falls naturally into the container on the conveying system composed of the conveyor belt and conveyor structure in the comparison document below, and is transferred to the next process.

[0036] The equipment achieves a continuous operation mode of "half of the temporary storage cylinder 9 is closed for feeding and weighing, and the other half of the temporary storage cylinder 9 is opened for unloading", which greatly improves filling efficiency and metering accuracy.
