Method/Step 1 The performance of computer quilting machines can be divided into many types, so to buy a good quilting machine, the main factor is the materials used in key parts of the machine, such as the motor, synchronous belt, and machine head. If you choose plastic or nylon parts for the synchronous belt of the synchronous wheel, you need to be careful. It won't take long, and it depends on the specifications of the materials in each part. If the square tube is less than 8 * 8, you need to consider the stability of the machine's operation. II Functional features 1 Thickness adjustment function: To adjust different thicknesses, you can follow the relevant instructions to adjust the depth of the quilting. 2. Pattern storage function: The computer quilting machine disk can store patterns for a long time, and users can choose to add patterns according to their needs. Its operation is simple, convenient, and fast. 3. Set the thread step function: strong reliability, uniform thread steps, and the pattern is not easily deformed. Spinning shuttle function: It can effectively prevent wire breakage. 4. Broken wire detection function: When the wire is broken, the system automatically stops. Floor occupancy rate: Computer quilting machines occupy a small area, but the size of the quilting is large. 5. Information display function: You can see spindle speed, parking factor, output statistics, remaining memory, and other displays on the display. 6. Safety devices: Computers, motors, machines, etc. will automatically shut down in case of abnormal phenomena, and the screen will display fault content. 7. Reinforcement sewing function: After activating the reinforcement sewing function, the sewing machine will automatically stitch back and forth at specific points. 8. Power outage memory function: When there is a power outage or power outage during the operation process, or when there is a problem with the sewing machine (needle or thread) that needs to be stopped, the computer sewing machine can automatically and quickly move forward or backward along the pattern movement route. And when it is necessary to continue quilting. It can automatically or manually return to the sewing point when the machine is stopped for further sewing. 9. Pattern function: The pattern is expanded or reduced by 50% -200% horizontally and vertically on one side, and the unit is automatically repaired by 1%. During the operation, if there is a missing line due to a broken line or no bottom line. It can automatically or manually use the specified needle to return along the direction of the stitch for patching. III The principle of computer quilting machines is the same as that of quilting machines, both of which use XY-Z type motion systems. The XY axis controls the movement of the machine head; The Z-axis controls the sewing of the machine head. (1) Z-axis movement - synchronous operation of the machine head and base controlled by a stepper motor (2) X-axis movement - left and right movement of the sewing machine head; (3) Y-axis movement - the forward and backward movement of the head of the quilting machine. IV Disadvantages Summary: (1) Difficulty in repairing computer quilting machines;(2) Operation also requires a certain computer foundation; (3) Compared to ordinary quilting machines, the price is slightly higher. V Single needle computerized quilting machine is a type of computerized quilting machine that only has one head, so it is called a single needle computerized quilting machine. His applications are very extensive, and he can be widely used for sewing various quilts, sleeping bags, bed covers, and curtains. Its advantages are: good machine stability, low price, adjustable flower size, simple operation, good quilting thickness, uniform needle size, and silent machine. Taking bedding as an example, the mechanism of action of 6. Bedding is generally composed of two parts: tire material and outer textile fabric, which can be divided into flocculent tire and loose fiber. The structure and shape of the loose fiber shaped bedding core are not fixed, easy to flow and shrink, and the thickness is uneven. In order to make the outer layer of the fabric and the inner core of the bedding tightly fixed, and to make the thickness of the bedding uniform, the outer layer of the fabric and the inner core are sewn together in a decorative pattern (including stitching) in a straight line. This process of increasing aesthetics and practicality is called quilting.
