Description

Technical Field

[0001] The utility model relates to the technical field of bobbin cases, in particular to a bobbin case suitable for a bottom thread sewing machine. Background Art

[0002] The bobbin and the bobbin case are mechanical parts used in sewing machines or embroidery machines, and the two are used in combination. The existing bobbin needs to be separated from the bobbin case when winding the bottom thread and then completed on the winding machine. After the bobbin is wound with the bottom thread, it is installed in the bobbin case, and then the bobbin case with the bobbin installed is installed in the rotary hook of the sewing machine or embroidery machine for use. After the bottom thread on the bobbin is used up, the bobbin is disassembled and rewound, and this process is repeated. A large number of rotary hooks are used each time in a sewing machine or embroidery machine, and the bottom thread needs to be replaced every once in a while. Each time the bobbin is replaced with the bottom thread, it needs to be disassembled from the bobbin case and then installed. If it is operated manually, it is time-consuming and labor-intensive, affecting production efficiency.

[0003] Although there are devices that automatically disassemble and assemble the bobbin core and the bobbin case, the bobbin case plate used for the bobbin case in the bottom thread machine is mostly clamped by directly inserting the bobbin case into the corresponding groove. This method is prone to the bobbin case falling off. If it falls off, it is not conducive to subsequent use. A bobbin case suitable for the bottom thread machine is needed to solve this problem.
