Mechanical knowledge base: "quilting machine"

Quilting machine is a textile machine used to sew mattresses, bedspreads, quilts and other linear patterns. It is similar to the principle of a sewing machine. (The sewing machine moves: the textile moves, the machine stops. The quilting machine moves. The machine moves. The textile is stationary.)

Quilting machine principle

The quilting machine is literally explained as a quilting machine. Let's say "quilting." According to the explanation given in "Ci Hai," quilting is the use of long needles to sew a textile fabric with interlayers, so that the batt inside it is fixed. In the beginning, people quilted by hand. After inventing the sewing machine, people began to study the quilting machine. In about 1991, China introduced the first mechanical quilting machine. It was also then that our country began to have its own quilting. However, at that time, people knew little about quilting, so most quilts were exported.

The three-dimensional motion of the quilting machine is as follows:

The quilting machine is a system that uses XY-Z motion. The XY axis controls the movement of the head and the Z axis controls the quilting of the head.

(1) Z-axis movement - movement of the quilting needle up and down.

(2) Movement in the X-axis direction - the head of the quilting machine moves right and left.

(3) Movement in the Y-axis direction - movement of the head of the quilting machine back and forth.

(4) Movement of the X and Y axes - depending on a template under the machine, quilting according to the pattern trend above.

This shows that the performance of the quilting machine mainly depends on his motion control system.

Quilting machine function:

In the case of bedding, the bedding is generally made up of two parts, the material for the booties and the textiles for the appearance, and the slivers are separated by slivers and loose fibers. Loose and fibrillar cores are not fixed in structure and shape, easy to flow and shrink groups, uneven thickness. In order to tightly fix the outer layer of the bedding fabric and the inner core so that the bedding is thick and thin, the outer layer of the fabric and the inner core are stitched (including stitching) side by side in a line or decorative pattern. The practical process is called quilting. After such a quilted bedding or mattress, it is called a quilting or quilting pad. In the past, quilted products were basically completed by hand. The main products were quilting and quilting pads. The difference between them and the bedding used in the average family was that there was a quilting process, and the operating procedure was to sew and sew. Millions of households use workshop-style processing methods, the disadvantages of which are low yield, poor pattern consistency and complicated operation process. In the 1990s, the mechanical multi-needle quilting machine entered China with high yield and good consistency. However, the pattern was simple, there were few changes, it was impossible to reverse the cloth, the printing was impossible, and the compounding was the main process. The processing quilt and the core were the main products.
