Description

Technical Field

[0001] This utility model relates to the field of bar packaging technology, and in particular to a buffer device for a bar packaging machine. Background Technology

[0002] In the bar production industry, finished bars need to be transferred to the packaging area via a conveyor line for centralized bundling. To achieve orderly collection of bars, the industry's conventional practice is to set up a blocking structure at the end of the conveyor line to temporarily stockpile the continuously conveyed bars, and start the packaging operation after the quantity is reached.

[0003] Currently, the most widely used method is to install a rigid barrier plate at the output end of the conveyor line, which directly blocks the high-speed flowing bars and forces them to stack. This method is simple in structure and low in cost, but as production scale expands and the demand for high-value-added bars increases, its inherent defects become more and more prominent, seriously affecting product quality and production efficiency.

[0004] The core problem with traditional barrier methods lies in the significant impact damage: Firstly, the bars suffer severe damage. Driven by the conveyor line, the bars often move at high speeds of 1.5-3 m / s, resulting in substantial impact forces when colliding with rigid barrier plates. This leads to defects such as dents and deformation at the impact ends, and may even cause internal lattice damage, causing a surge in the scrap rate of precision bars. Secondly, the equipment suffers from high wear and tear. The barrier plates are subjected to high-frequency impacts over a long period, requiring frequent replacements, which increases maintenance costs and disrupts production continuity due to downtime. Therefore, a buffer device for the bar packaging area was designed to cushion the transported bars, reducing the impact force at the end of transport and fundamentally solving the series of problems inherent in traditional barrier methods. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned traditional methods, the purpose of this utility model is to provide a buffer device for a bar packing machine, which can buffer the transported bars, reduce the impact force at the end of the transport, and solve the problems of traditional blocking methods from the root.

One end of the second connecting rod is connected to a fixing lug on the fixed bracket, and the other end of the second connecting rod is provided with a second pressure roller.

A lifting bracket 5 is provided on one side of the first fixed frame 1, which can be rotated by the rotating shaft 4 to lift the bars on the second rollers 10, thereby guiding the bars to the upper part of the receiving bracket 3 to realize the storage of the whole batch of bars and facilitate subsequent packaging operations.

[0026] It should be further explained that a buffer mechanism 6 is set on the upper part of the second fixed frame 2 to buffer the impact force on the finished bar during transportation. This mechanism is specifically designed for buffering the bar.

The outer wall of the first connecting rod 604 is fitted with a first pressure spring 605, which together form a first elastic structure. This elastic structure can provide a stable preload to the guide support 603, ensuring that the first pressure roller 606 is in close contact with the bar.

In order to make the second pressure roller 615 fit with the bar, the second fixing ear 610 at the lower part of the second connecting rod 609 is connected to the third fixing ear 612 on the connecting bracket 611 through the telescopic rod 613.

[0033] It should be noted that the barrier bar 8 is designed to allow the bars to enter and exit the storage, thus enabling the bars to be stacked.

[0034] As shown in the figure - Figure 5 As shown, the lifting bracket 5 is mounted on the rotating shaft 4, and one end of the rotating shaft 4 is connected to the output shaft of the drive motor via a coupling; the second pressure roller 615 is mounted inside the connecting seat 614 at one end of the second connecting rod 609.
