What are the thread take-up mechanisms of industrial sewing machines
Industrial sewing machines are sewing machines suitable for sewing workpieces for mass production in sewing factories or other industrial sectors. Industrial sewing machines are used in factories that require sewing machines for clothing, shoes and hats, etc.
When the sewing machine is sewing, in the process of forming stitches, it plays a role in conveying, recovering needles and threads and tightening stitches.
Mainly can be divided into the following:
1. Cam thread take-up mechanism: the mechanism that the cam drives the thread take-up lever to move
2. Connecting rod thread take-up mechanism: a mechanism driven by a four-bar linkage mechanism to move the thread take-up mechanism
3. Slider thread take-up mechanism: a mechanism driven by the crank slider mechanism to move the thread take-up mechanism
4. Rotary thread take-up mechanism: a mechanism that uses one or two discs or other shaped components equipped with thread take-up pins to perform thread take-up movement with a rotating motion
5. Needle bar thread take-up mechanism: a mechanism that fixes the thread passing or clamping device on the needle bar, or directly fixes the thread take-up bar mounted on the needle bar.
Nowadays, the sewing machine equipment is constantly improving, from the old-fashioned pedal to today's mechatronics, and now the living standard is constantly improving, and the sewing materials are also diversified. The ordinary sewing machine equipment can no longer meet the sewing requirements. At this time, we need to use it. Industrial sewing machine equipment, and Dongguan Intelligent Technology has 15 years of experience in the production and development of industrial sewing machines, with sufficient supply and quality assurance. Today we will learn what is an automatic sewing machine.
The automatic sewing machine is a large-scale special equipment for sewing. It adopts double-needle and four-thread chain connection, fully enclosed, and automatic oiling. Due to the use of internationally recognized equipment and equipment, the machine has the best noise and stability when it moves, and is durable. been widely used.
Due to the different stitch structures of automatic sewing machines, the adjustment of the position of the needle bar is based on the vacuum, while others are based on the needle point. No matter which one is, a good match can make the woven bag automatic sewing machine Better performance.

1. Automatic head turning: After completing a quilting operation, the seam head can be turned up automatically, which is convenient for the replacement of quilted products.
2. Wire break detection: When the wire is broken, it will automatically stop, the red light of the wire break detection device will be on, and it can go back to the broken wire for quilting.
3. Step quilting: Various step quilting operations can be performed
4. Emergency stop protection: press the red emergency stop button at any time during work, the quilting machine will immediately power off and stop
5. Process setting: It has the settings of various practical process parameters such as stitch selection, angle correction, pattern scaling, etc. High-speed and accurate quilting at 2000 rpm, low noise, long machine life, and quilting that meets customer needs. The target quilting area of high-quality and high-yield quilted products is equal to the size of the machine, and the smallest machine installation area is achieved. ) drives the machine head to run in the X direction, and the servo motor (optional) drives the machine head to run in the Y direction, and the embroidery frame is fixed, which ensures the minimum machine transmission distance and stable long-term work. Fast and accurate, and avoids damage and replacement of the handpiece in the future.
《Needle zero position》 Set the machine origin, after the zero reset is completed, start the pull rod to make the machine head pass the needle zero position probe and then stop, move the machine head to the left side of the needle bed by hand, and align the left outer side of the machine head with the first position of the needle bed. At the needle, press the F1 key to write the currently displayed needle value. (First, enter the number of needles in one inch of the flat knitting machine and the total number of needles in the flat knitting machine, and then set the synchronous belt pitch correction parameters)
