Description

Technical Field

[0001] The utility model relates to the technical field of transfer hook processing, in particular to a sawing groove device used for processing transfer hooks for a socks machine. Background Art

[0002] When producing socks, semi-finished socks are usually produced in the needle cylinder of the sock machine first, and the sock toes are not sewn at this time. Then the semi-finished socks are taken out of the needle cylinder by a transfer device and transferred to the seam head plate. After the seam head plate is closed, the sock toes are sewn. The transfer plate sleeve barb or transfer hook, transfer needle, and transfer tooth are the accessories in the transfer device.

[0003] Existing transfer hooks often have no notch structure. When the yarn is transferred from the transfer disk to the seam head disk, there is a possibility of yarn derailment. Once the yarn derails, the whole sock will be scrapped, or the operator needs to manually hang the thread needle by needle, which is very troublesome. Therefore, in order to prevent the yarn from derailing, a notch structure needs to be processed at the end of the transfer hook. In the actual production process, the notch structure is often processed by a sawing groove device. However, due to the small size of the transfer hook, the existing sawing groove device is very inconvenient to fix the transfer hook. In addition, the transfer hook needs to be processed on both sides, and the existing sawing groove device cannot meet the processing requirements. Therefore, in order to solve the above problems, it is particularly important to design a sawing groove device for processing the transfer hook for the sock machine. Summary of the invention

[0004] In order to solve the above-mentioned problem, the utility model designs a sawing groove device for processing transfer hooks for sock machines. The transfer hook can be quickly fixed through the cooperation of the first fixed lower mold and the first upper pressure plate, as well as the cooperation of the second fixed lower mold and the second upper pressure plate, thereby achieving the purpose of facilitating processing. Moreover, the design makes the placement grooves on the first fixed lower mold and the second fixed lower mold symmetrically arranged. By adopting this structure, the processing of the front and back sides of the transfer hook can be smoothly completed, thereby increasing practical performance.
