Description

Technical Field

[0001] The utility model relates to the technical field of food production feeding, in particular to a quantitative feeding hopper. Background Art

[0002] With the improvement of people's living standards, the demand for food consumption market continues to increase. The food industry is regarded as a sunrise industry with a huge market size and great development potential. In this context, the food industry is facing many changes and challenges. In order to improve production efficiency and reduce costs, most food production lines adopt mechanized automatic production lines. In automatic production lines, quantitative feeding hoppers are indispensable. The existing quantitative feeding hoppers are mostly composed of hoppers, weighing sensors and pneumatic valves. When weighing materials, the materials enter the hopper, the weighing sensor detects the weight of the materials, and the feeding is stopped after the weight reaches the standard. The pneumatic valve opens and the quantitative materials enter the next process. The traditional quantitative feeding hopper has only one hopper, and the weighing and feeding work are carried out in sequence, which has low production efficiency. When working, especially when quantitatively weighing powdered materials, the materials are fed in a static state. Due to the light weight of the materials, the materials often adhere to the inner wall of the hopper, causing errors. For this reason, we propose a quantitative feeding hopper. Utility Model Content

[0024] The working principle of a quantitative feeding hopper provided by the utility model is as follows: when the quantitative feeding hopper is used to weigh materials, the outer conveyor belt feeds the materials into the hopper 3, the single chip microcomputer 5 controls the weighing sensor 48 to work, and the weighing sensor 48 weighs the materials inside the hopper 3. When the materials in the hopper 3 reach the specified weight, the weighing sensor 48 sends an electrical signal to the single chip microcomputer 5, and the single chip microcomputer 5 controls the motor 471 to operate. The output shaft of the motor 471 drives the gear 472 to rotate. Because the gear 472 is meshed and connected with the outer gear ring 473, the outer gear ring 473 also rotates synchronously with the rotation of the gear 472, and the connecting frame 2 Then it rotates 180 degrees. At this time, the hopper 3 located below the external conveyor belt continues to receive and weigh the materials, and the hopper 3 located above the next process starts to unload the materials. The single-chip computer 5 controls the electric push rod 464 to work, and the telescopic end of the electric push rod 464 extends to the right. As the telescopic end of the electric push rod 464 moves to the right, the telescopic end of the electric push rod 464 contacts the connecting rod 462. The telescopic end of the electric push rod 464 continues to move to the right, pushing the connecting rod 462 to the right, and the partition 461 also slides to the right out of the hopper 3, and the tension spring 463 is expanded. At the same time, as the connecting rod 462 moves to the right, the sliding frame 41 also moves to the right. 3, and the sliding column 42 moves to the right, and the sliding column 42 also moves to the right synchronously. When the middle part of the sliding column 42 contacts the protrusion 45, the protrusion 45 squeezes the sliding column 42 to make the sliding column 42 move to the end away from the center of the hopper 3, and the distance between the hammer 43 and the surface of the hopper 3 becomes larger, and the tension spring 1 44 is expanded under the force. Since the speed of the connecting rod 462 moving to the right is very fast, the sliding column 42 will quickly pass the protrusion 45. After the sliding column 42 passes the protrusion 45, the sliding column 42 is not restricted, and the tension spring 1 44 is not forced to shrink quickly, driving the sliding column 42 and the hammer 43 back to their original positions. During this period, the hammer 43 will quickly hit the surface of the hopper 3, causing the hopper 3 to vibrate and adhere to the inner wall of the hopper 3. The material on the hopper 3 will quickly slide down and enter the next process, and this cycle repeats until the discharge port at the lower end of the hopper 3 is completely opened, and the entire interior of the hopper 3 falls to the next process, the telescopic end of the electric push rod 464 is retracted, and the tension spring 2 463 shrinks without force, driving the partition 461 and the connecting rod 462 back to their original positions, the sliding frame 41, the sliding column 42 and the hammer 43 also return to the original position, and the hammer 43 strikes the surface of the hopper 3 again to make the material fall more thoroughly. At this time, the hopper 3 located under the external conveyor belt completes the weighing work, and the connecting frame 2 rotates 180 degrees with the hopper 3 to continue to perform weighing and unloading work alternately, and this cycle repeats.
