Description

Technical Field

[0001] The invention belongs to the technical field of embroidery machines and relates to an embroidery control method of an embroidery machine. Background Art

[0002] The embroidery machine is used to embroider patterns on embroidery materials (embroidery cloth, leather, etc.). The thread trimming mechanism of the embroidery machine is used to cut the upper thread and the lower thread after the embroidery is completed. Figure 2-5 The thread trimming mechanism of the embroidery machine includes a mounting seat 1, a swingable movable blade 2, a fixed blade 3 and a thread locking spring 5. A rotatable shaft 4 is installed on the mounting seat 1, the movable blade 2 is installed at the upper end of the shaft 4, and the output end of the external driving mechanism is connected to the shaft 4. When working, the external driving mechanism drives the movable blade 2 to swing through the shaft 4. The fixed blade 2 is fixed to the mounting seat 1 and is located on the upper side of the movable blade 2. The thread locking spring 5 is fixed to the mounting seat 1 and is located on the lower side of the movable blade 2.

[0003] When the embroidery machine is embroidering, the movable blade 2 and the fixed blade 3 are in a staggered state. Figure 5 As shown in the figure, when the embroidery is completed and the thread needs to be trimmed, the external driving mechanism drives the movable blade 2 to swing backward and open. After the movable blade 2 is fully opened, the movable blade 2 and the fixed blade 3 are separated from each other. Then the external driving mechanism drives the movable blade 2 to swing forward. When the movable blade 2 is fully opened, the movable blade 2 and the fixed blade 3 cut the upper thread and the lower thread alternately. Figure 5 As shown, the thread locking spring piece 5 and the moving blade 2 cooperate to clamp and lock the bottom line, so as to achieve the positioning of the bottom line and prevent the bottom line from moving, so that the upper thread and the bottom line form a loop to pull the bottom line up during the next embroidery, so as to achieve the embroidery again. However, the bottom line is easily clamped too tightly by the thread locking spring piece 5 and the moving blade 2, and the clamping force on the bottom line is too large, so that the upper thread cannot pull the bottom line up, resulting in the inability to embroider normally. Summary of the invention

[0004] The purpose of the present invention is to provide an embroidery control method for an embroidery machine to solve the above technical problems.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an embroidery control method of an embroidery machine, comprising the following steps:

[0006] Step S01: when embroidery is completed, the movable blade of the thread trimming mechanism is controlled to swing, and when the movable blade swings into position, the movable blade and the fixed blade of the thread trimming mechanism alternately cut the upper thread and the lower thread, and at this time, the state of the movable blade is set to the thread cutting state;

[0007] Step S02: After the thread trimming mechanism has finished trimming the thread, the movable blade is controlled to swing back. The movable blade swings back to the position. At this time, the state of the movable blade is set to the retreat and loosening state. From the cutting thread state to the retreat and loosening state, the retreat swing angle of the movable blade is α.

[0008] Furthermore, in step S02, after the thread trimming mechanism has finished trimming the thread, the embroidery machine embroiders again, and when the embroidery needle moves the upper thread downward through the embroidery material and the front section of the lower thread to form a loop and is pulled upward, the movable blade is controlled to swing back into place.

[0009] Furthermore, the moving blade retreat swing angle α is 0-30°.

[0010] Furthermore, the retracting swing angle α of the movable blade is 20°.

[0011] Furthermore, in the step S02, after the upper thread and the lower thread are looped and pulled up, the movable blade is controlled to reset, and the movable blade swings from the retracted thread-loosening state to the thread-cutting state.

[0012] Furthermore, the embroidery machine is provided with a mounting seat, a rotatable shaft is provided on the mounting seat, the movable blade is mounted on the shaft, the shaft is connected to the output end of the external driving mechanism, the fixed blade is fixed to the mounting seat, the fixed blade is located on the upper side of the movable blade, and a thread locking spring is also installed on the mounting seat, and the thread spring is located on the lower side of the movable blade.

[0013] Beneficial effects of the present invention: The embroidery control method of the embroidery machine of the present invention controls the movable blade to retreat and swing at a certain angle after the thread cutting mechanism has finished cutting the thread, so as to slightly loosen the bottom line, so that the bottom line will not be clamped too tightly by the passive blade and the thread locking spring sheet, and the bottom line can be smoothly pulled up by the upper thread when embroidering again, which greatly improves the success rate of the bottom line being pulled up by the upper thread when embroidering again, and ensures that the embroidery machine can perform embroidery work normally.
