Description

Technical Field

[0001] The utility model relates to the technical field of adjustable quilting machines, in particular to an adjustable quilting machine. Background Art

[0002] Existing quilting machines include a machine head and a beam for mounting the machine head. The machine heads of most existing adjustable quilting machines are generally fixedly connected to the beam and cannot move, or can only move horizontally along the beam and cannot move forward and backward. In order to improve efficiency, adjustable quilting machines are generally provided with machine heads on both sides. The machine heads on both sides are staggered and can work simultaneously. Since the position of the machine head is fixed, the distance between the machine heads on both sides is also fixed, that is, the stitch length is fixed. When faced with different sewing requirements, only embroidery with corresponding stitch lengths can be sewn, which is not easy to adjust, narrowing the scope of application of the adjustable quilting machine. At the same time, when replacing and installing the shuttle assembly of the machine head, it is inconvenient to replace the shuttle assembly due to the narrow distance between the machine heads on both sides. When replacing the shuttle assembly of one machine head, in order to facilitate replacement, it is usually necessary to disassemble certain parts of the machine head on the opposite side to achieve the avoidance effect. This not only wastes time, but frequent disassembly will also accelerate the damage of parts. Utility Model Content
