Description

Technical Field

[0001] This utility model relates to the field of packaging weighing technology, specifically a quantitative weighing mechanism for packaging equipment. Background Technology

[0002] On the packaging production line, quantitative weighing is a key step in ensuring the consistency of product packaging specifications.

[0003] Traditional quantitative weighing mechanisms typically use a fixed-height weighing platform in conjunction with conveying equipment to complete the weighing operation. Since the height of conveying equipment varies from production line to production line, the fixed-height weighing platform is difficult to adapt flexibly, which requires additional adjustments to the conveyor structure or the addition of shims during installation, increasing the complexity and cost of equipment integration.

[0004] Therefore, we propose a quantitative weighing mechanism for packaging equipment. Utility Model Content

There are two sets of material support frames 9, which are fixed on the left and right sides of the upper outer surface of the weighing platform 8. The material support frame 9 includes a supporting base rod 13, a supporting arm 14, and a loading platform plate 15. The upper part of the material support frame 9 passes through the feeding rollers in the middle of the roller conveyor 1.

[0022] The rectangular box column 4 is fixed to the middle of the upper outer surface of the base plate 3. The hydraulic rod 5 is located in the middle of the rectangular box column 4. The lower outer surface of the cylinder of the hydraulic rod 5 is fixedly connected to the middle of the upper outer surface of the base plate 3. The upper outer surface of the piston rod of the hydraulic rod 5 is fixedly connected to the middle of the lower outer surface of the mounting plate 7. There are two sets of connecting arms 6, which are fixed between the left and right sides of the upper outer wall of the cylinder of the hydraulic rod 5 and the left and right sides of the upper part of the inner cavity of the rectangular box column 4. There are four sets of fixing blocks 10, guide rings 11 and guide rods 12. The four sets of fixing blocks 10 are fixed to the upper left and right sides of the upper outer surface of both ends of the rectangular box column 4. On both sides, four sets of guide rods 12 are fixed at the four corners of the lower outer surface of the mounting plate 7, and the guide ring 11 is fixed on the outer surface of the end of the guide ring 11 away from the rectangular box column 4; the guide rod 12 passes through the guide ring 11, and the outer wall of the guide rod 12 and the inner wall of the guide ring 11 are slidably connected; the weighing platform 8 is fixed on the upper outer surface of the mounting plate 7, and the support bottom rod 13 in the two sets of material support frames 9 is fixed on the left and right sides of the upper outer surface of the weighing platform 8.

[0023] It should be noted that this utility model is a quantitative weighing mechanism for packaging equipment. The roller conveyor 1 described in this document belongs to the prior art and can be effectively known to those skilled in the art, so it will not be described in detail here. The lifting weighing structure 2 is set up so that when weighing materials, the operation of the hydraulic rod 5 drives the mounting plate 7 and the weighing platform 8 to rise. The weighing platform 8 drives the upper part of the two sets of material support frames 9 to pass through to the upper part of the roller conveyor 1. Then, the receiving tank is weighed through the loading platform plate 15 in the two sets of material support frames 9. Weighing platform 8 weighs the material during filling. After filling, the hydraulic rod 5 in the lifting weighing structure 2 drives the mounting plate 7 and weighing platform 8 to descend. The weighing platform 8 drives the material support frame 9 to descend. The loading platform plate 15 in the material support frame 9 descends to the lower part of the roller conveyor 1, leaving the can body on the upper part of the roller conveyor 1. The roller conveyor 1 transports the can body. When the mounting plate 7 and weighing platform 8 are raised and lowered, the mounting plate 7 drives the guide rod 12 to rise and fall along the guide ring 11, improving the stability of the raising and lowering of the mounting plate 7, weighing platform 8 and material support frame 9.
