Bobbin case storing mechanism of automatic bobbin case replacing device

Abstract

The invention provides a bobbin case storing mechanism of an automatic bobbin case replacing device, and belongs to the technical field of sewing devices. The problem that replacing of a base line of an existing bobbin case storing mechanism is complex is solved. The bobbin case storing mechanism of the automatic bobbin case replacing device comprises a rotating disc, a rotating shaft and a driving piece. The driving piece is connected with the rotating shaft, a plurality of installing frames are fixedly connected to the rotating disc, and a check ring is arranged between the rotating shaft and the rotating disc and fixedly connected with the rotating shaft. The check ring and the rotating disc are circumferentially fixed. A shaft sleeve penetrates through the middle of the rotating disc and the middle of the check ring. A blind hole is formed in the middle of the top of the rotating shaft. A spring is arranged on a sliding shaft in a sleeving mode, one end of the spring abuts against the shaft sleeve, and the other end of the spring abuts against the sliding shaft. An annular groove is formed in the circumference outer side wall of the sliding shaft, and an installing hole is formed in the bottom of the shaft sleeve. Steel balls are arranged in the installing hole, and the diameter of the steel balls is larger than the wall thickness of the shaft sleeve and the aperture of the outer side wall of the shaft sleeve. The bobbin case storing mechanism has the advantage that a bobbin case and the base line are convenient to replace.

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
