Description

Crochet hook mechanism of woolen sweater embedding and clamping machine

Technical Field

The utility model belongs to the technical field of sewing machine, a woollen sweater buries crochet hook mechanism who presss from both sides machine is related to.

Background

The fell seam machine is one of the main devices in the knitting industry for sewing the panels, collars, sleeves, etc. of knitted garments, and the performance of the machine is directly related to the sewing quality of the fabric. The transmission mechanism of the linking machine is an important part of the linking machine, and whether the structure is reasonable or not directly influences the service performance, the sewing quality and the working efficiency of the embedding machine.

The traditional embedding and clamping machine is generally composed of a machine base, a transmission mechanism arranged on the machine base and a case arranged on the machine base and covering the transmission mechanism, wherein the transmission mechanism is simply formed by matching a cam with a connecting rod. Although the structure is simple, the manufacturing and processing are difficult, the movement is easy to be inconsistent, the transmission is unstable, the tape is easy to be clamped, and phenomena such as yarn skipping, foaming, yarn breakage and the like are easy to occur.

For this reason, an improved fastener embedding machine is designed, such as the patent disclosed by the intellectual property office of china: improved sweater vertical type fell seam machine [ application No. CN 201120431857.0; public publication No. CN202279919U discloses the following technical solutions: the device comprises a base, a transmission mechanism arranged on the base and a case arranged on the base and covering the transmission mechanism, wherein the transmission mechanism is externally connected with a driving mechanism and comprises a main shaft and four cam mechanisms arranged on the main shaft; the transmission mechanism side is also provided with a gear bracket, and the gear bracket is provided with a gear component matched with the transmission mechanism. The four cam mechanisms include: and the third cam mechanism consists of a third eccentric wheel arranged on the main shaft, an adjusting screw rod pivoted with the third eccentric wheel and a line pressing rod, wherein the tail end of the line pressing rod is provided with a triangular hook.

However, in the above scheme, the third cam mechanism is mainly driven by the third eccentric wheel on one side only, and the driving force is only on one side of the tail end of the thread pressing rod, during the high-speed sewing process of the embedding machine, the thread pressing rod is stressed on one side to cause the reciprocating swing of the thread pressing rod to generate vibration and deflection, so that the operation of the triangular hook is unstable. Therefore, the crochet hook mechanism cannot meet the requirement of fine and stable operation of the sewing machine.
