Abstract

Disclosed is a computer laser embroidery machine, which comprises laser generators(10), a frame(20), a beam (21)fixed on the frame, needle bar boxes of the embroidery machine fixed on the beam and laser cutters(11) installed beside the needle bar boxes. The laser emitted from the laser generators(10) enters into a laser coupler(12) and the laser is focused before entering into an optical fiber(13). The laser coupled by the coupler(12) is transmitted to the laser cutter(11) through the optical fiber(13). Since the laser is transmitted via the optical fiber(13), the embroidery machine has simple structure and saves space. The laser cutter(11) can be arbitrarily fixed on the needle bar boxes of the embroidery machine, thus the embroidery machine occupies less area and saves steel.

Abstract

A feeding-in device of a quilting machine for automatically adjusting the distance between two feeding rollers during quilting includes a base (1) and a cross beam (2) located above the base. A first feeding roller (5) is provided on the right side of the base, and a second feeding roller (8) is provided on the corresponding right side of the cross beam. The left side of the base is provided with a first bearing (3) which is mounted with a first shaft (4) whose output end is fixedly connected with the first feeding roller. The left side of the cross beam is provided with a second bearing (6) which is mounted with a second shaft (7) whose output end is fixedly connected with the second feeding roller. The first shaft is driven by a motor (11). A cylinder (9) is provided on the base, and the cross beam is mounted on the arm of the cylinder. When the textiles to be quilted are drawn towards the front of the quilting machine, the feeding-in device can adjust the distance between the two feeding rollers according to the varied thickness of the textiles to keep a suitable pressure between the two feeding rollers, which ensures the textiles to be fed properly.
