Laser cutting device of embroidery machine and laser embroidery integrated machine thereof

Abstract

The invention relates to an embroidery machine laser cutting device and a laser embroidery unity machine thereof, which belongs to the technical field of a textile fabrication plant. A laser cutting head comprises a hollow pipe, a hollow motion bar which is connected with the interior of the hollow pipe in a sliding way, a mask body which is arranged at the lower end of the hollow motion bar; the pipe wall of the hollow pipe is provided with at least a first strip-shaped through hole which is parallel to the axes of the hollow pipe; a shank which is connected with the hollow motion bar is arranged in the first strip-shaped through hole, and one end of the shank extends to the outside of the first strip-shaped through hole; a lifting actuating mechanism is connected with the shank; the body of the mask body takes the hollow structure and is divided into an upper cavity and a lower cavity by a medial conical surface; the cavity wall of the upper cavity is provided with a fanning hole which is communicated with the upper cavity; the lower cavity is provided with a smoking hole which is communicated with the lower cavity. The invention facilitates to the movement of an embroidery frame of the embroidery machine, has smaller convex focus in the mask body, more accurate cutting operation and facilitates that the mask body absorbs smoke generated by laser cutting, thus having no pollution to working environment.

Description

technical field [0001] The invention relates to a laser cutting device for an embroidery machine and an integrated laser embroidery machine thereof, belonging to the technical field of textile processing equipment. Background technique [0002] A laser embroidery all-in-one machine (notification number: CN201010774), which is a laser embroidery all-in-one machine, which includes a support frame, a worktable is arranged on the support frame, and an embroidery frame capable of two-dimensional movement is arranged on the worktable. The support frame is also connected with a beam, on which a single or multiple embroidery devices are arranged, and a laser tube, a laser light path, and a laser cutting head connected to the embroidery device are connected to the beam, and the laser cutting head is arranged beside the embroidery device . In order for the laser cutting head to cut the cloth accurately, the distance between the cover at the lower end of the laser cutting head and the...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an embroidery machine that is convenient for the movement of the embroidery frame, the focal length of the convex lens in the cover is small, the cutting operation is more accurate, and it is beneficial for the cover to absorb the smoke generated by laser cutting without polluting the working environment. The machine laser cutting device and its laser embroidery all-in-one machine solve the problem that the height of the laser cutting head and the worktable is relatively fixed in the prior art. In some cases, the embroidery position is closer to the frame edge of the embroidery frame, and the outermost If the laser cutting head needs to be moved outside the embroidery frame, the cover at the lower end of the laser cutting head will collide with the embroidery frame and hinder the movement of the embroidery frame, which will affect the operation of the embroidery machine and cause inconvenience; and if the lower end of the laser cutting head If the cover moves up, the focal length of the lens inside the cover needs to be enlarged, but the lens with a larger focal length will affect the cutting effect and cutting control on the one hand, and because the distance between the cover and the fabric in the embroidery frame is relatively large Large, the smoke generated during the cutting process is easy to disperse, which is not conducive to the pollution of the working environment caused by the smoking of the cover body
