Description

Technical Field

[0001] This utility model relates to the technical field of bird's nest filling equipment, and in particular to a bird's nest filling equipment based on dynamic weighing. Background Technology

[0002] In the food and beverage processing industry, the automated filling process of liquid bird's nest typically employs a multi-filling-head synchronous operation to fill different filling tanks. During operation, this filling system is prone to localized pipe blockages due to factors such as residue buildup on the inner walls of the pipes and wear on the filling valve components. Simultaneously, the pressure balance of each filling branch can dynamically change due to pump output fluctuations and differences in pipe length. These operating conditions can lead to deviations in the actual output flow rate of each filling head, ultimately resulting in variations in the amount of liquid bird's nest filled in different filling tanks.

[0003] In the quality control process of current filling equipment, traditional weighing conveyor belts are often used as dynamic weighing units. These devices, based on the principle of collecting the overall weight during continuous conveying, can only monitor the total weight of groups of filling cans on the conveyor belt, and cannot accurately measure the weight of individual cans. When an abnormal filling volume occurs in a single can, the existing system cannot locate the problematic can in real time, resulting in some products that do not meet the weight requirements flowing into subsequent processes. Utility Model Content

[0004] The purpose of this invention is to provide a bird's nest filling device based on dynamic weighing, which realizes dynamic weighing after bird's nest filling and separates products with non-compliant weights.

[0005] This utility model provides a bird's nest filling device based on dynamic weighing, including a first conveyor and a second conveyor arranged at intervals. A filling mechanism is mounted above the first conveyor. A dynamic weighing mechanism is arranged between the first conveyor and the second conveyor. The dynamic weighing mechanism includes a lifting weighing component and two guide roller frames symmetrically arranged on both sides of the lifting weighing component. The lifting weighing component includes a guide plate and a transmission chain. Two first sprockets that cooperate with the transmission chain are rotatably mounted on the guide plate. Multiple support members are arranged at intervals on the transmission chain. Weighing roller frames are rotatably mounted on the support members. Weighing sensors are installed on the weighing roller frames. An annular guide groove is opened on the guide plate and is offset from the transmission chain. A sliding rod is provided on the weighing roller frame and is offset from its rotation axis. The sliding rod is inserted into the annular guide groove.

[0006] Furthermore, the filling mechanism is fixedly installed above the first conveyor via a frame. The filling mechanism includes a quantitative filling component and a filling head. The quantitative filling component includes a quantitative cavity communicating with the bird's nest storage tank, a piston slidably disposed in the quantitative cavity, and a first cylinder that drives the piston to reciprocate. The filling head is connected to the quantitative cavity via a material conveying pipe.

[0007] Furthermore, the filling head includes a main pipe connected to the conveying pipe and a discharge nozzle located at the bottom of the main pipe, and an anti-drip valve is installed on the main pipe.

[0008] Furthermore, the first conveyor is symmetrically provided with guide plates corresponding to the positions of the filling heads.

[0009] Furthermore, a second cylinder is provided on one side of the first conveyor, and a baffle is fixedly installed at the output end of the second cylinder.

[0010] Furthermore, the piston is provided with an annular sealing ring on its edge that fits against the inner wall of the metering chamber.

[0011] Furthermore, the frame is provided with a height adjustment mechanism for driving the filling head to rise and fall. The height adjustment mechanism includes a lead screw, a lifting plate, and a motor for driving the lead screw to rotate. The lifting plate is connected to the lead screw in a transmission cooperation. The frame is provided with a mounting plate, and guide rods are symmetrically provided on both sides of the mounting plate. The two ends of the lifting plate are slidably mounted on the guide rods, and the filling head is fixed to the bottom of the lifting plate.

[0012] Furthermore, a proximity sensor and a feeding rod are installed on the second conveyor. A fourth cylinder is horizontally rotatably installed on one side of the second conveyor. A linkage push rod is provided at the bottom end of the feeding rod. The output end of the fourth cylinder is hinged to the outer end of the linkage push rod. The fourth cylinder is electrically connected to the proximity sensor through a main controller.

[0013] Furthermore, a pushing assembly is provided on one side of the guide roller frame near the second conveyor. The pushing assembly includes a fifth cylinder, and an arc-shaped pushing plate is fixedly installed at the output end of the fifth cylinder.

[0014] Furthermore, the lifting and weighing assembly also includes a sub-controller, and the weighing sensor on each of the weighing roller frames is electrically connected to the sub-controller. The wireless transmission module of the sub-controller is connected to the wireless receiving module of the computer.

[0015] This invention employs a dynamic weighing mechanism between a first conveyor and a second conveyor. Multiple weighing rollers equipped with weighing sensors are spaced apart on the transmission chain of the lifting weighing component. During the transfer of filling cans from the first to the second conveyor, the weighing rollers support individual cans through guide rollers, allowing dynamic weighing of the liquid bird's nest inside each can using the weighing sensors. The annular guide groove on the guide plate engages with the staggered sliding rods on the weighing rollers, ensuring the weighing rollers remain horizontal during movement, guaranteeing weighing accuracy and preventing cans from tipping over. This design overcomes the shortcomings of traditional weighing conveyors in accurately weighing individual cans and locating cans with abnormal weights. It enables real-time acquisition of single-can weight data, accurately identifying non-compliant products, and improving the precision and efficiency of quality control in liquid bird's nest filling production.

[0026] Example 1

[0027] like Figures 1-5 As shown, this utility model provides a bird's nest filling device based on dynamic weighing, including a first conveyor 1 and a second conveyor 2 arranged at intervals. A filling mechanism 3 is mounted above the first conveyor 1. A dynamic weighing mechanism 4 is arranged between the first conveyor 1 and the second conveyor 2. The first conveyor 1, the second conveyor 2, the filling mechanism 3, and the dynamic weighing mechanism 4 are all coordinated and controlled by a general control system. The dynamic weighing mechanism 4 is used to dynamically weigh the filled bird's nest, which facilitates the screening of products with non-compliant weights. The dynamic weighing mechanism 4 includes a lifting weighing component and two guide roller frames 8 symmetrically arranged on both sides of the lifting weighing component. Multiple guide rollers are spaced apart on the guide roller frames 8. The heavy-duty component includes a guide plate 6 and a transmission chain 5. Two first sprockets that cooperate with the transmission chain 5 are rotatably mounted on the guide plate 6. Multiple support members are spaced apart on the transmission chain 5, and a weighing idler frame 7 is rotatably mounted on the support members. Multiple strip-shaped trays are spaced apart on the weighing idler frame 7. The width of the trays is less than the distance between the two guide rollers, so that when the transmission chain 5 drives the weighing idler frame 7 to move, the weighing idler frame 7 can pass through the guide roller frame 8, thereby lifting the can used to hold bird's nest that moves to the guide roller frame 8. A stop bar is provided on the guide rail frame located on one side of the first conveyor 1, near the transmission chain 5, so that the filling can 10 stops moving when it reaches the stop bar, waiting to be lifted by the weighing idler frame 7. Weighing roller frame 7 is equipped with weighing sensor 9. The lifting weighing assembly also includes a sub-controller. The weighing sensor 9 on each weighing roller frame 7 is electrically connected to the sub-controller. The weight signal sensed by the weighing sensor 9 is fed back to the sub-controller. The wireless transmission module of the sub-controller encodes the weighing data into a wireless signal, and the wireless receiving module of the computer decodes the signal into weighing data.

[0028] To ensure the weighing idler frame 7 remains horizontal when driven by the transmission chain 5, an annular guide groove 601 is provided on the guide plate 6, offset from the transmission chain 5. The weighing idler frame 7 is provided with a slide rod 701 offset from its rotation axis, inserted into the annular guide groove 601. The diameter of the slide rod 701 is equal to the width of the annular guide groove 601. Alternatively, a roller can be rotatably mounted at the end of the slide rod 701, with the diameter of the roller equal to the width of the annular guide groove 601. This prevents the weighing guide frame from swaying. When the transmission chain 5 drives the weighing idler frame 7, the slide rod 701 is confined within the annular guide groove 601, thus ensuring the weighing idler frame 7 remains horizontal during movement.

[0029] The filling mechanism 3 is fixedly installed above the first conveyor 1 via a frame 306. The filling mechanism 3 includes a quantitative filling component and a filling head 312. The quantitative filling component includes a quantitative chamber 302 connected to the bird's nest storage tank 301 via an electromagnetic three-way valve 304, a piston slidably disposed in the quantitative chamber 302, and a first cylinder 303 that drives the piston to reciprocate. The output end of the first cylinder 303 is fixedly connected to the piston in the quantitative chamber 302 via multiple piston rods. The first cylinder 303 drives the pistons in multiple quantitative chambers 302 to move synchronously. The piston is equipped with an annular sealing ring on its edge that fits against the inner wall of the metering chamber 302. The feed pipe 305 on the filling head 312 is connected to the metering chamber 302 via a solenoid three-way valve 304. When the first cylinder 303 drives the piston to rise, the solenoid three-way valve 304 is controlled to connect the metering chamber 302 to the bird's nest storage tank 301, realizing metered extraction. When the first cylinder 303 drives the piston to fall, the solenoid three-way valve 304 is controlled to connect the metering chamber 302 to the filling head 312, realizing the injection of liquid bird's nest into the filling tank 10 at the filling station. The filling head 312 includes a main pipe connected to the feed pipe 305 and a discharge nozzle located at the bottom of the main pipe. An anti-drip valve is installed on the main pipe to prevent liquid leakage. When the piston moves downward under the drive of the first cylinder 303, the liquid bird's nest in the metering chamber 302 is compressed and pressure is generated. The pressure value can be monitored by setting a pressure sensor on the piston, so as to preliminarily determine whether the material in the metering chamber 302 has reached the preset filling amount.

[0030] In order to ensure that the filling can 10 accurately reaches directly below the filling head 312 during filling, guide plates 310 are symmetrically provided on the first conveyor 1 at the position corresponding to the filling head 312, and the distance between the two guide plates 310 is the same as the outer diameter of the filling can 10.

[0031] In order to keep multiple filling cans 10 stationary, a second cylinder 308 and a third cylinder 309 are respectively installed at the front and rear ends of the filling station. Both the output ends of the second cylinder 308 and the third cylinder 309 are fixedly equipped with baffles. When the first conveyor 1 drives the filling cans 10 forward, the front second cylinder 308 first extends to block the filling cans 10 using the baffles. As the first conveyor 1 operates, when the number of filling cans 10 arranged at the filling station matches the number of filling heads 312, the rear third cylinder 309 extends its baffle to block subsequent filling cans 10. After filling, the second cylinder 308 at the front end of the filling tank 10 retracts. The filled filling tank 10 continues to move forward under the drive of the first conveyor 1. After all the filled filling tanks 10 have left the filling station, the second cylinder 308 extends the baffle again, and at the same time the third cylinder 309 retracts to release the subsequent filling tanks 10 into the filling station. Accordingly, in order to achieve coordinated control of the second cylinder 308 and the third cylinder 309, a sensor for sensing the filling tank 10 should be set on one side of the first conveyor 1 at the position corresponding to the filling station.

[0032] To prevent splashing of liquid bird's nest during filling, a height adjustment mechanism is provided on the frame 306 to drive the filling head 312 to rise and fall. This mechanism allows the bottom end of the filling head 312 to extend into the filling tank 10 for filling. The height adjustment mechanism includes a lead screw 314, a lifting plate 311, and a motor 313 that drives the lead screw 314 to rotate. The filling head 312 is fixed to the bottom of the lifting plate 311. The lifting plate 311 is connected to the lead screw 314 through a transmission cooperation. The lifting plate 311 is slidably mounted on the mounting plate 307 of the frame 306. Guide rods 315 are symmetrically provided on both sides of the mounting plate 307, and the two ends of the lifting head are slidably mounted on the guide rods 315 respectively.

[0033] A pushing assembly is provided on one side of the guide roller frame 8 near the second conveyor 2. The pushing assembly includes a fifth cylinder 11, and an arc-shaped pushing plate 12 is fixedly installed at the output end of the fifth cylinder 11. When the weighing roller frame 7 sends the weighed filling can 10 to the guide roller frame 8 near the second conveyor 2, the fifth cylinder 11 drives the pushing plate 12 to push the filling can 10 onto the second conveyor 2.

[0034] In order to screen products that do not meet the weight requirements, a proximity sensor and a material-pulling rod 13 are installed on the second conveyor 2. A fourth cylinder 15 is horizontally rotatably installed on one side of the second conveyor 2. A linkage push rod 16 is provided at the bottom end of the material-pulling rod 13. The output end of the fourth cylinder 15 is hinged to the outer end of the linkage push rod 16. The fourth cylinder 15 is electrically connected to the proximity sensor through the main controller. When the filling can 10 enters the second conveyor 2 after weighing, if the filling weight data is not compliant, the fourth cylinder 15 drives the material-pulling rod 13 to rotate and tilt on the second conveyor 2, screening the products that do not meet the weight requirements into the receiving tray 14.

[0035] Working principle

[0036] First, the entire system is started. The first conveyor 1, the second conveyor 2, the filling mechanism 3, and the dynamic weighing mechanism 4 are all activated. The main control system controls the electromagnetic three-way valve 304 to connect the metering chamber 302 and the bird's nest storage tank 301. The first cylinder 303 drives multiple piston rods to rise. Under the action of the piston inside the metering chamber 302, the bird's nest to be filled is sucked into the metering chamber 302. Then, the electromagnetic three-way valve 304 connects the metering chamber 302 to the conveying pipe on the filling head 312, entering the waiting filling mode. During the process, under the action of the first conveyor 1, multiple filling tanks 10 enter the filling station in sequence. Under the action of the second cylinder 308 and the guide plate 310, multiple filling tanks 10 stop directly below the corresponding filling head 312. Then, the motor 313 drives the filling head on the lifting plate 311 to descend, while the first cylinder 303 drives the piston rod to descend. The bird's nest is injected into the filling tank 10. After filling is completed, the second cylinder 308 retracts and continues to move forward under the drive of the first conveyor 1. After all the filling tanks 10 at the filling station have left the filling station, the third cylinder 309 retracts and continues to make the filling tanks 10 on the first conveyor 1 enter the filling station in sequence (after all the filling tanks 10 have left the filling station, the second cylinder 308 will extend again). After filling, the filling tanks 10 are pushed into the guide roller frame 8 in sequence, waiting to be lifted and weighed by the weighing roller frame 7. The weighing data is fed back to the computer's main control system by the sub-controller. After weighing, the filling tanks 10 are sent into the guide roller frame 8 on the other side and then pushed into the second conveyor 2 by the fifth cylinder 11. The main control system controls the fourth cylinder 15 to work according to the weighing data, driving the material feeding rod to rotate and introduce the filling tanks 10 with non-compliant weighing data into the receiving tray 14.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
