Description

Technical Field

[0001] The utility model belongs to the technical field of winding machines and relates to a fork of a winding machine. Background Art

[0002] In the production process of chemical fiber filaments, the key device for the forming of the bobbin package is the fork (composed of a fork disc and fork blades). The upper and lower forks move in opposite directions, precisely guiding the filament bundle to reciprocate at a specified position, and finally realizing the uniform winding of the bobbin. This process requires that the starting positions of the upper and lower forks must strictly maintain a fixed phase to ensure that the filament bundle is accurately guided to the specified position, thereby ensuring the quality of the bobbin forming.

[0003] However, in actual production, it is inevitable that melt particles or other sundries will fall into the high-speed running winding machine. As Figure 1 shown, once these sundries enter the high-speed running fork device, especially when they are stuck between the upper and lower fork blades, the two reversely rotating high-speed fork blades will be blocked by the sundries at the same time, thereby generating a huge lateral resistance, resulting in the phase shift of the fork. The phase shift of the fork not only destroys the original precise guiding mechanism of the fork, making the filament bundle unable to be accurately deflected to the specified position, resulting in uneven laying and abnormal forming of the bobbin, but also seriously damages the overall quality of the product. More seriously, once it is detected that the bobbin forming is poor and it is confirmed that it is caused by the phase shift of the fork, the production line often needs to be shut down urgently, and the affected fork device needs to be disassembled and adjusted. This process not only takes time and effort, but also directly reduces the production efficiency.

[0004] Therefore, it is of great significance to develop a fork of a winding machine that can solve the above problems. Content of the Utility Model
