A bobbin case storage mechanism of an automatic bobbin case replacement device

Abstract

The invention provides a bobbin case storage mechanism of a bobbin case automatic replacement device, which belongs to the technical field of sewing equipment. The utility model solves the troublesome problem of replacing the bottom thread in the existing bobbin case storage mechanism. The bobbin case storage mechanism of the bobbin case automatic changing device includes a turntable, a rotating shaft and a driving part. The driving part is connected with the rotating shaft. The rotating shaft is fixedly connected, the retaining ring and the turntable are fixed in the circumferential direction, the middle of the turntable and the retaining ring is pierced with a bushing, the middle of the top of the rotating shaft has a blind hole, the spring is sleeved on the sliding shaft, and one end of the spring is against the On the shaft sleeve, the other end leans against the sliding shaft. There is an annular groove on the circumferential outer wall of the sliding shaft. The bottom of the shaft sleeve has a mounting hole, and a steel ball is arranged in the mounting hole. The diameter of the steel ball is larger than the wall thickness of the shaft sleeve. , and the diameter of the steel ball is greater than the diameter of the hole on the outer wall of the sleeve. The bobbin case storage mechanism has the advantages of convenient bobbin case replacement and bottom thread.

Description

technical field [0001] The invention belongs to the technical field of sewing equipment, and relates to a bobbin case storage mechanism of a bobbin case automatic changing device. Background technique [0002] In the prior art, the sewing machine needs to frequently replace the bottom thread during the sewing process or the embroidery machine during the embroidery process. The bottom thread is installed in the bobbin, and the bobbin is installed in the bobbin case. It can be regarded as an integrated structure. Replacing the bobbin case and bobbin is to replace the bobbin thread. However, since the bobbin and bobbin case with the bobbin thread are under the machine table, it is troublesome to replace the bobbin and bobbin case, especially for sewing machines. Or when the embroidery machine needs bottom threads of multiple colors, the replacement is frequent, and each replacement needs to spend a lot of time and labor, and it is easy to make mistakes when changing.

Problems solved by technology

[0004] In the rotary hook moving access mechanism with this structure, the radial cross section of the rotary hook access dial is circular, and several rotary hook storage racks are fixedly connected to the outer wall of the rotary hook access rotary disc. The pick-up turntable is fixedly connected with the gear through the shaft. After the hook access turntable is installed, it is difficult to remove it. When some or some bottom threads in the hook need to be replaced after use, the hooks can only be replaced one by one under the table. Shuttle, due to the small operating space, it is troublesome to replace the hook
