Description

Technical Field

[0001] The utility model relates to the technical field of baling machines, in particular to a tensioning mechanism of a baling machine. Background Art

[0002] The primary purpose of a baler is to securely package items for transport and storage. The tensioning mechanism quickly and effectively tightens the strapping, increasing packaging speed and efficiency. This ensures that the packaged items are not loosened or damaged by vibration or external forces during transport, while also preventing excessive squeezing or damage to the items.

[0003] Chinese utility model patent CN221542074U discloses a cable tie baler with an auxiliary tensioning mechanism, comprising a placement platform and two supporting legs fixed to the bottom surface of the placement platform, a fixing mechanism disposed above the placement platform, and a strapping mechanism disposed below the placement platform; the strapping mechanism is located below the fixing mechanism. The strapping mechanism allows materials to be tightened during packaging, thereby ensuring greater stability during the packaging process. Furthermore, the height of the lifting plate can be controlled during the tightening process, allowing cable ties of varying thicknesses to be clamped and fixed. A friction pad can be provided to increase friction during the fixing of the cable ties, ensuring greater stability during the clamping and fixing process. A transmission unit can be provided to transport the cable ties during bundling, and a pressure roller can be provided to prevent the cable ties from flipping during transportation.

[0004] In order to make the cable ties more stable when being clamped and fixed, the cable tie baler with the auxiliary tensioning mechanism is provided with a friction pad on the top of the lifting plate. However, the cable tie baler with the auxiliary tensioning mechanism does not have the function of removing the friction pad. After long-term use, the friction pad will gradually wear out, and its friction and clamping ability will be reduced. If the worn friction pad cannot be removed and replaced, the baler will become unstable when clamping the cable tie, and may even be unable to effectively fix the cable tie, thereby affecting the reliability and safety of the packaging.

[0013] Beneficial effects:

[0014] 1. The tensioning mechanism of the baler is equipped with T-blocks and bolts. When replacing the friction pad, the bolts are turned to release the restriction of the T-block, and the friction pad is pulled out until the T-block moves out of the T-slot, thereby realizing the disassembly of the friction pad. The same principle applies when installing. This provides great convenience for the staff to replace the friction pad in time, effectively improves work efficiency, ensures that the friction pad always has strong friction, avoids unstable clamping of the cable tie due to excessive wear of the friction pad, and improves the reliability and safety of packaging.

When the handle is pulled toward the side away from the placement table, the return spring is stretched while the telescopic rod is extended. When the limit block moves out of the sealing box, the staff can turn the handle to drive the first threaded rod to rotate, so as to adjust the position of the clamping plate. After the movement is completed, the handle is released. Under the elastic force of the return spring, the limit block is inserted into the limit groove and the telescopic rod is shortened, thereby achieving the purpose of limiting the handle, reducing the risk of handle rotation due to misoperation, external force impact or vibration, and further improving the stability of the clamping plate.
