Embodiment approach
[0032] In one embodiment, the fixed knife adopts the existing fixed knife, that is, the installation position of the fixed knife and the structure of the fixed knife are not changed (see figure 1 ); The moving knife adopts the moving knife according to the design of the present invention. The improvement of the moving knife mainly lies in changing the position of the moving knife edge. figure 1 Among them, the installation point of the fixed knife 3 on the shuttle bed 1 is on a straight line with the shaft center of the knife bar. On the moving knife, design the moving knife edge located in the critical trajectory G and close to the edge of the critical trajectory; or, design the moving knife edge on the critical trajectory G (see figure 2 ). In this embodiment, the installation position of the moving knife does not change, that is, the position of the knife rod of the driving mechanism of the moving knife does not change. The present invention can also change the installa...

The invention discloses a trimming device and a trimming method of an embroidery machine, and belongs to the technical field of embroidery machines. The device comprises a movable cutter, a fixed cutter and a movable cutter driving mechanism which are all arranged on a shuttle race, wherein the movable cutter is mounted on a cutter bar of the movable cutter driving mechanism; the movable cutter is provided with a movable cutter blade located on a critical track, or the movable cutter is provided with a movable cutter blade located in the critical track and close to the edge of the critical track; the critical track is constructed by taking the axis of the cutter bar as a circle center and the distance from the circle center to a needle plate hole as a radius; the movable cutter driving mechanism drives the movable cutter to move towards the fixed cutter, the movable cutter trimming end of the movable cutter forks out a bottom thread to be trimmed and a surface thread to be trimmed during movement and continues to move towards the fixed cutter until the movable cutter coincides with the fixed cutter, the movable cutter blade and a fixed cutter blade jointly act to cut off the bottom thread and the surface thread, and the intersection point of the movable cutter blade and the fixed cutter blade is close to the needle plate hole. The method is realized based on the device. An existing trimming device is slightly changed, the end of the bottom thread left on the back face of the fabric after trimming is short, and the embroidery quality is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of embroidery machines, and in particular relates to an embroidery machine thread trimming device and an embroidery machine thread trimming method. Background technique [0002] At present, for the embroidery machine industry, when one graphic unit of embroidery is completed and another graphic unit is started to be embroidered, it is necessary to trim the upper thread and the lower thread under the cloth surface. The existing embroidery machine structure comprises an embroidery machine head, a thread buckle device, and a thread trimmer, and the thread trimmer is used for thread trimming. Specifically, an upper thread driven by the needle of the embroidery machine passes through the cloth surface and is picked up by the rotary hook and separated into two strands. After knotting, cut off a strand of upper thread and lower thread with scissors, and the cut strand of upper thread and lower thread forms a threa...
