Background
The bobbin thread of the sewing machine includes a bobbin case and a bobbin, and when the sewing machine is operated for a certain period of time and the bobbin thread on the bobbin is used up, the bobbin case needs to be replaced. The current sewing machines require different bobbin cases with threads of different colors to be replaced to meet the sewing requirements. In the prior art, the bobbin case is generally manually replaced by a worker, when the bobbin case is manually replaced, the bobbin case with the used bobbin thread is taken out firstly, and then the bobbin case to be replaced, which is fully wound with the bobbin thread, is installed in the bobbin case, so that time is consumed. The workload is greater if the bobbin case of the multi-color bobbin thread is replaced. In the actual operation of the sewing machine, a bobbin thread can be used up in about 20 to 30 minutes, so that the operation of replacing the bobbin case is time-consuming and cumbersome.

After the cam follower 10 moves to the highest point of the first section of the vertical through groove 41, that is, the slide block 7 moves to the highest point of the guide rod 8, the cam follower 10 continues to move along the second section of the arc-shaped through groove 42 under the action of the driving force, the slide block 7 on the other side of the cam follower 10 drives the guide rod 8 and the moving block 9 to rotate, the slide block 7 simultaneously drives the bobbin case jaws 18 and the bobbin case 1 to be replaced to rotate 90 degrees along the second section of the arc-shaped through groove 42, and the guide rod 8 rotates to be horizontal.
After the guide rod 8 rotates to be horizontal, the cam follower 10 continues to move along the third section of the horizontal through groove 43, the sliding block 7 on the other side of the cam follower 10 drives the bobbin case clamping jaw 18 and the bobbin case 1 to be replaced to move along the guide rod 8 in the horizontal direction until the bobbin case 1 to be replaced is moved to the position below the panel 2 of the sewing machine, the bobbin case clamping jaw 18 releases the bobbin case 1 to be replaced, and the bobbin case to be replaced is installed.
The process of removing the empty bobbin case with the bottom thread used up from below the sewing machine panel 2 is opposite to the above-described mounting process and will not be described again.
During the process that the cam follower 10 ascends and descends or translates along the first vertical through groove 41 or the third horizontal through groove 43, the rotating block 9 and the guide rod 8 are kept stationary, and the sliding block 7 moves up and down or moves horizontally along the guide rod 8.
In the process of reversing the cam follower 10 along the second arc-shaped through groove 42, the guide rod 8 is driven by the slide block 7 to rotate, so that the rotating block 9 is driven to rotate synchronously. In the whole rotation process, the angle changes of the guide rod 8 and the rotating block 9 are the same as the included angles of the first vertical through groove 41 and the third horizontal through groove 43, and are both 90 degrees, so that the bobbin case 1 to be replaced is in a vertical state after being installed below the sewing machine panel 2 from an initial flat state installed on the bobbin case clamping disc 13. In this embodiment, the state when the circular plane of the bobbin case is parallel to the horizontal plane is defined as a flat state.
