A three-dimensional laser embroidery machine

Abstract

The embodiment of the present invention discloses a three-dimensional laser embroidery machine, which includes a workbench, a number of laser cutting heads arranged at equal intervals on the beam of the workbench, an embroidery machine head, and a laser cutting head slidably arranged on the workbench below the laser cutting head. Double-layer cloth locking mechanism; the laser cutting head light source is driven by a high-voltage stable circuit CO 2 Generated by a laser; the double-layer cloth locking mechanism includes an inner frame and an outer frame, and the cloth on it is loaded by a zipper and tightened by a tensioning cylinder. With the present invention, the laser cutting head can stably output laser light through the high-voltage stabilizing circuit, preventing unnecessary cutting defects of the double-layer cloth from being affected by the fluctuation of the AC grid power supply, and the upper and lower layers can be easily checked by the double-layer cloth locking mechanism. The replacement of cloth avoids the repositioning of the upper and lower layers of cloth during layering processing, effectively reducing the complex procedure of changing the lower layer of cloth, using the invention can increase the production efficiency by more than 50%, and improve the quality of embroidery to the greatest extent .

Description

technical field [0001] The invention relates to an embroidery machine, in particular to a three-dimensional laser embroidery machine. Background technique [0002] Embroidering colorful three-dimensional patterns on cloth is a traditional handicraft of my country, but handmade cannot meet the needs of people's growing material and cultural life. With the development and progress of science and technology, the embroidery process has gradually developed from manual embroidery to mechanized and computerized embroidery through the research and development of a large number of technicians. One of the embroidery processes is this: superimpose colored cloth on the base cloth, and manually Or the machine embroiders patterns such as flowers, and then cuts off the excess color cloth, so that a beautiful color embroidery pattern is formed on the base cloth. In this process, the cutting of the excess color cloth can be manually cut, but any With the development of computer technology a...

Problems solved by technology

[0003] At present, in the embroidery production process, when using laser to cut double-layer embroidery lace, it is necessary to strictly control the power of the laser and the focus of the laser cutting point. The reason is that the laser is easy to penetrate when cutting the pattern on the carrier. Miscutting the carrier through the pattern on the upper layer, or attenuating the intensity of the laser itself due to gasification smoke generated by laser cutting, resulting in wire skipping during the pattern cutting process, the pattern cannot be completely cut, and improper control of the cutting laser also makes the edge of the pattern Burnt yellow will affect the quality, and the exhaust gas produced by laser cutting will also pollute the workshop and damage the health of workers. Although the existing technology uses a water-soluble cloth or hot-melt film in the middle when lasering multiple layers , resulting in an increase in the cutting process, and the post-processing process is complicated

[0004] On the other hand, in the process of embroidering the bottom layer of fabric and then superimposing the upper layer of fabric for embroidery, it is necessary to fix the double layer of fabric separately. Due to the limitations of the machine itself, the method is to loosen the clamp after the upper layer of embroidery is processed. The lower layer of fabric is placed under the upper layer of fabric. Since the upper layer of fabric is loosened and shifted and shrinks, it is necessary to lock the double-layer fabric and restore the tensioned shape of the upper layer of fabric before it was released. This process It is not easy for the operator to fix the double layer, but the operator spends a lot of time to fix the double layer, but the desired effect is still not achieved, and the lower layer of fabric is often folded, and the quality of the three-dimensional embroidery cannot be effectively improved. Therefore, there is an urgent need for a multi-process coordination, automatic High-level computerized embroidery equipment
