Description

Technical Field

[0001] The utility model relates to the technical field of laser embroidery machines, in particular to a laser head mounting mechanism for embroidery machines. Background Art

[0002] In the prior art, there is an embroidery machine with an alternating arrangement of fixed laser and flat embroidery mechanisms. Multiple laser transmitters are fixed on the frame to guide the laser onto the fabric through the light guide arm and lens assembly. The embroidery machine drives the embroidery frame to move according to the design trajectory of the pattern to complete the fabric cutting. Then switch to the flat embroidery head to embroider other parts of the pattern, and finally complete the complete embroidery product.

[0003] Fixed laser processing speed is slow, and is affected by the inertia of the embroidery frame, which will lead to poor cutting effect at corner points. The laser power is uniformly controlled without power calibration, and the laser power control is not precise enough.

[0004] Another existing technology is the application of large galvanometer laser to embroidery machines. A single embroidery machine is equipped with a large galvanometer laser, or even multiple embroidery machines are equipped with a large galvanometer laser to save costs. During use, individual embroidery stations are cut one by one.

[0005] Although the single-time cutting speed of this method is much higher than that of fixed laser, the overall operating efficiency is low and the production efficiency does not meet the use requirements. At the same time, the cutting format will also be affected by the format of the galvanometer, and a pattern may need to be completed in multiple times.

[0006] Therefore, those skilled in the art provide an embroidery machine laser head mounting mechanism to solve the problems raised in the above background technology. Utility Model Content
