Specific embodiments

[0021] Referring to Figures 1-5 , a weighing device for can processing includes a processing platform 1. On one side of the processing platform 1, two conveyor platforms 3 are clamped and installed. Inside both conveyor platforms 3, roller conveyor belts 4 are rotatably installed. On both roller conveyor belts 4, multiple cans 5 are placed; on the top of the processing platform 1, a main control console 2 is fixedly installed. Inside the processing platform 1, a weighing sensor 6 is fixedly installed. On the top of the processing platform 1, a six - jaw disc 8 is rotatably installed; on the outside of the processing platform 1, a support 17 is fixedly installed. On one side of the support 17, a filling tank 18 is fixedly installed. At the bottom of the filling tank 18, a valve pipeline 19 is fixedly installed. On one side of the valve pipeline 19, a sealing pipeline 22 is installed through.

[0022] In this embodiment, multiple transmission columns 9 are fixedly installed on the top of the six - jaw disc 8, and multiple clamps 10 are fixedly installed on the outside of the six - jaw disc 8, facilitating the movement of the cans 5 driven by the multiple clamps 10.

[0023] In this embodiment, a rotating base 12 is rotatably installed on the top of the six - jaw disc 8. A sliding groove is opened at the bottom of the rotating base 12. Inside the sliding groove, a clamp crank 11 is slidably installed. The bottom of the clamp crank 11 is slidably installed on the top of the six - jaw disc 8.

[0024] In this embodiment, a fixed column 7 is rotatably installed on the top of the rotating base 12. One end of the fixed column 7 is fixedly installed at the bottom of the support 17. The top of the clamp crank 11 is fixedly installed with a crankshaft 13, and a crank 14 is rotatably sleeved on the crankshaft 13.

[0025] In this embodiment, a protective housing 16 is fixedly installed at the bottom of the support 17. Inside the protective housing 16, a servo motor 15 is fixedly installed. The output shaft of the servo motor 15 is connected to the crank 14, and the top of the crank 14 is rotatably installed at the bottom of the protective housing 16, enabling the crank 14 to be driven to rotate by the servo motor 15.

[0026] In this embodiment, a filling metal block 20 is fixedly installed inside the valve pipeline 19, and a sealing metal block 21 is slidably installed inside the sealing pipeline 22. A filling port is formed at the top of the filling metal block 20. A sealing plate 23 is fixedly installed inside the sealing pipeline 22. The arrangement of the sealing plate 23 helps to prevent the main body of the electric push rod 24 from contacting the raw material.

[0027] In this embodiment, an electric push rod 24 is fixedly installed inside the sealing pipeline 22. The output shaft of the electric push rod 24 is connected to the sealing metal block 21. A support spring 25 is fixedly installed on one side of the sealing metal block 21. One end of the support spring 25 is fixedly installed on one side of the sealing plate 23. A filling head 26 is fixedly installed at the bottom of the valve pipeline 19.

[0028] Working principle: When processing the can 5, after the can 5 is moved to the designated position through the roller conveyor belt 4, the staff starts the servo motor 15 through the main control console 2. The start of the servo motor 15 drives the crank 14 to rotate. The crank 14 rotates around the output shaft of the servo motor 15 as the center, driving the crankshaft 13 to move. The rotation of the crankshaft 13 drives the clamping crank 11 to move. At the same time, the rotating base 12 limits the rotation angle of the clamping crank 11. Therefore, the clamping crank 11 can only move and rotate within a certain range. When the clamping crank 11 moves to the designated position, the transmission column 9 slides into the card slot of the clamping crank 11. The movement and rotation of the clamping crank 11 drive the transmission column 9 to move. The movement of the transmission column 9 drives the six-jaw disc 8 to rotate. When the clamping crank 11 moves to the designated position, the transmission column 9 leaves the card slot, and the six-jaw disc 8 stops rotating. When the clamping crank 11 completes a movement cycle, due to the same spacing between the transmission columns 9, the second transmission column 9 can just slide into the front fork of the clamping crank 11, driving the six-jaw disc 8 to continue rotating in a cycle. Since a plurality of clamps 10 are fixedly installed on the outer side of the six-jaw disc 8, the movement of the plurality of clamps 10 will drive the can 5 to move when rotating. When the can 5 moves onto the weighing sensor 6, the clamping crank 11 moves to the designated position and disengages from the transmission column 9. Therefore, the six-jaw disc 8 stops rotating, providing time for weighing and filling the can 5. After the weighing sensor 6 is turned on and senses the weight of the can 5, it feeds back to the main control console 2. The main control console distinguishes according to the set program based on the current weight of the can whether the can is to be filled. When it is identified that the can is not filled, the main control console 2 starts the electric push rod 24. The start of the electric push rod 24 drives the sealing metal block 21 to move. The movement of the sealing metal block 21 exposes the filling port, and the raw material naturally falls into the can 5 through the filling port and the filling head 26. When the set weight is reached, the weighing sensor 6 feeds back to the main control console 2, and the main control console 2 controls the electric push rod 24 to reset to prevent the raw material from dripping. At this time, the clamping crank 11 contacts the second transmission column 9, thereby driving it to move, and the six-jaw disc 8 rotates, moving the filled can into the next process.

[0029] The technical progress obtained by the present utility model compared with the prior art is that it can make there be a movement gap when transporting the can 5, and use this gap time for weighing and filling. While being stable and convenient, it improves the working efficiency of the device, and can reduce the phenomenon of raw material dripping from the filling component after filling through the set mechanism. While reducing waste, it also improves the practicality of the device.
