Aoling PC31026D New High speed Stitching Series - Fully Automatic Thread Cutting

AolingPC31026D-01CB/UTThe high-speed overlock sewing machine, also known as a special sewing machine, sews chain stitch threads. There are many traces in this lineUsed for rolling collars, rolling edges, folding edges, flat seams, splicing seams, and decorative edges of knitted clothing. In recent years, it has becomeThe styles of clothing vary greatly,The overlock sewing machine is also commonly used for sewing decorative stitches, and the stitches sewn by the overlock sewing machine areThere are various variations in the formula, such as threeThe four thread stitch (stitch 407) can be changed to a two thread three thread stitch (stitch 406)Can be sewn with two needles and three threadsFor two needle four thread stitching or three needle five thread stitching (stitch 602 or 605), in order to better understand the purpose of the stitching machine,The following research will focus on the conveying power, head design, and changes in stitching of the overlock sewing machine, in order to fully utilize its functionsThe road.

1、 The conveying power system of the sewing machine

Because the overlock sewing machine is mostly used for sewing knitted fabrics, it often uses two sets of feeding teeth at the front and back to transport the sewing materialThe conveying power is that two sets of feeding teeth are relatively independent. You can adjust the synchronous conveying action of the front and rear two sets of feeding teeth, orThere is a distinction between fast and slow. When sewing elastic knitted fabrics and two-layer lightweight knitted fabrics, the feeding teeth can be adjustedThe feeding speed is faster than the differential tooth feeding speed, or the feeding speed of the feeding tooth is slower than the differential tooth feeding speed. Correctly adjust the feeding tooth andThe differential feeding speed can reduce the elongation and shrinkage deformation of the sewn fabric, making it more aesthetically pleasing.

2、 Design of the head type
The design of the head type of the overlock sewing machine is mostly a high platform device. In order to meet the production needs of various sewing processes, the head typeThe design also includes circular mouth arm around type, circular mouth arm out type, circular mouth arm in type, etc. The high platform type overlock sewing machine head is suitable for sewing long seamsFlat cutting of the mouth line trace; The round mouth wrapped arm type is designed for sewing the edges of rolled or folded cuffs; Round mouth arm typeIt is used for sewing seams on cylindrical parts, such as the seam on the bottom of sleeves and the seam on the side of pants; The round mouth arm type is designed for sewing underwear bottomsDesigned for the production of seam openings; In addition, the high platform machine head can be equipped with a slanted design to match the sewing of different shapes of cut pieces.Some sewing machines are designed with an installation position for a sewing accessory (sewing aid) on the right side of the machine head. As applied to edge rolling operationsMake the sewing process so that the sewing accessory can be connected to the right side of the needle board for sewing.

3、 Application of Stretching Machine in Production Process

（1） Make rolled edge stitching

Use bundling strips to wrap the rough edges of the cut piece around the sewing seam, and roll the edges if bare. The number of layers of seam material on the seam is too many and too thick, such as sticking to the bodyThe cut clothes may be uncomfortable to wear, but if a sewing machine is used to sew 602 (two needle four thread) or 605 (three thread)Stitching with five stitches can reduce the number of layers of sewing material on the seam from five to three by wrapping the rough edges of the bundleUse 406 (two needle three thread stitching) or 407 (three needle four thread stitching) stitches (remove the decorative thread covering the surface of the stitching machine)It can be changed from 602 trace to 406 trace, as shown in the figure. It is possible to install a sewing aid for rolling edges on the overlock machine for operationIt can both reduce the thickness of the seam and improve operational efficiency.

（2） After wrapping, stretch the seam
Knitted garments, after being sewn with overlock seams, may have protruding seams that do not fit snugly. In this case, the seams can be covered with stretch seamsFlat clothes. Make the protruding seam fit snugly, but this process often requires special needle plates and presser feet to fix the seam and make the operation more efficientEasy to control.

（3） The sewing process of adding lace
Due to the width between the two or three stitches of the tension stitch, there are also mesh like stitches that can cover the lace strip and be directly sewn inThe seam on the cutting piece. And there is no need to fold the edges of the cut to prevent loose edges, which can reduce the thickness of the seam and make it easier to wearComfortable, this method is commonly used for sewing women's knitted underwear.

（4） Folding edge stitching process

In order to reduce the thickness of the folded edges and seams, the edges of finished garments are often sewn with overlock seams and then sewn with single pleats or hidden stitchesProcessing, such as skirt hem, pant legs, cuffs, etc., can reduce the common occurrence of twisted edges due to double fold edge stitching caused by bending, butThis processing method requires two processes of overlock and then stitching to complete. If the style of the finished garment matches, 406 (two stitches, three stitches) can be appliedStitching is used to stitch the edges of a garment with a single fold. Combine two processes into one process to improve production efficiency.

（5） Sewing on elastic fabric

Due to the strong stretchability of the stretch line, it is particularly suitable for sewing knitted fabrics or other elastic fabrics, such as knitted T-shirtsUnderwear often uses a sewing machine. In addition, the stitching can be covered with a mesh like decorative thread on top, which not only has certain decorative properties, but alsoIn addition to decorative features, the operation of attaching visible patches to knitted/sweater bags can be sewn with this stretch stitch, which can reduce the thickness of the folded edges and also facilitate the operationEasy to make, without the need to fold and heat the seam on the edge of the sticker bag, the sticker bag can be directly sewn on, which can save operation processes and time.

Through the analysis of the above process applications, it can be seen that the use of the overlock machine is very wide. If its performance is effectively utilized, the appropriate machine head type can be selectedApplying the formula and pairing it with a suitable sewing aid at the appropriate time can better leverage the high-efficiency characteristics of the overlock machine.

People need maintenance, machines need lubrication. From JapanORENThe special machinery lubricant developed by the company can dry grind machinery for more than four hours at a high speed of 5000 revolutions per minute with just a small drop. It has good lubricity and stability. due toproductThe use of non-ionic surfactants extracted from various natural plants makes it unparalleled in terms of high temperature resistance and rust prevention compared to other oils. In addition; We also focused on solving the problem of surface cleanliness of machinery and equipment after long-term dripping of engine oil, without dripping, appearance corrosion, yellowing, peeling, etc., making it more environmentally friendly and healthy. Specially suitable for special requirements of external drip addition of special machinery equipment. The high-speed operation of mechanical parts during use can cause physical properties to heat up due to friction, and some machine components may experience operation difficulties or jamming, affecting the normal operation of the equipment. Therefore, this product uses non active lubricants extracted from natural plants to use dynamic braking and static energy to convert heat energy into power, suppress the friction coefficient, and immediately restore normal operation of machine components that are not running smoothly or jamming. Eliminating the issues of heat generation and noise caused by the physical properties of components during high-speed operation.

This product is extracted from all natural plants and is a colorless and transparent liquid with no irritating odor. It has no harm to the human body or skin and is more environmentally friendly, healthy, and has a longer lifespan. Suitable for high lubrication and maintenance of high-end mechanical equipment such as electronic drives, CNC machine tools, and precision transmissions.
