Thread take-up lever
Thread take-up lever help to pull the thread from the spool to feed it through the machine and lifts the thread back up out of the cloth after a stitch has been made. At the time of sewing this part goes "up and down" to pull the thread.
Thread cutter
The thread cutter is located on the underside of a needle plate where there is a needle hole that cuts needle and bobbin threads located between a piece of cloth and a rotary hook.
Thread tension dial
The thread tension dial is used to regulate the tension discs to tighten or loosen at the time of sewing. This dial helps to stitch properly by maintaining the proper tension level.
Face plate
Face plate is used to cover the oiling points of the needle bar, presser bar, and thread take-up lever. This project is from the unwanted contact of needle bar, pressure bar, and any other foreign particles.

First and foremost, it is essential to carefully measure the space available for the rack under the tabletop. This will help determine the size of the rack and ensure that it fits properly in the space provided. It is important to take into account any additional equipment or wiring that may need to be accommodated within the space.
In addition to measuring the available space, it is important to consider the weight and load capacity of the rack. A rack that is too heavy or has a low load capacity may not be suitable for certain types of equipment. It is important to carefully evaluate the needs of the equipment that will be housed in the rack to ensure that the rack is strong enough to support it.
Another key consideration is the accessibility of the rack once it is installed. Accessing the equipment within the rack should be easy and straightforward, without requiring extensive disassembly or rearrangement of the components. This can be achieved by ensuring that the rack is positioned in a location that is easy to reach and that all necessary wiring and connections are easily accessible.
In addition to these practical considerations, it can be beneficial to consider the aesthetics of the rack installation. In many cases, a well-designed and neatly installed rack can not only improve the functionality of the equipment it houses but also enhance the overall appearance of the space. Taking the time to carefully plan and execute the installation of the rack can pay off in terms of both functionality and visual appeal.
Ultimately, the key to ensuring a successful rack installation under a tabletop is careful planning and attention to detail. By taking the time to measure the available space, consider the load capacity and accessibility of the rack, and prioritize aesthetics, it is possible to create a highly functional and visually appealing installation that supports the equipment it houses for years to come.
Sewing Machine Main Parts
Sewing machine needle
The sewing machine needle piercing the fabric must harmonize with fabric thickness and density. Mismatched needles can cause frustrating issues like needle breakage, skipped stitches, puckering seams, and even damage to the fabric itself.
Industrial sewing machines utilize needles ranging from fine 5's to thick 26's. While lightweight fabrics take smaller, sharp needles, heavy canvas, and denim can withstand pounding from a size 16 or 23 thick needles. Matching needle size to fabric weight prevents unwanted needle deflection or breakage. Most common household machines accommodate universal needle sizes 11, 12, or 14.
Needle components include the shank clamped by the needle bar, the shaft passing through fabrics, and point-piercing layers. Based on point shape, common types are sharp for wovens and ballpoint for knits. Sharp points slice through fabrics neatly while ballpoints separate fibers more gently to preserve fabric structure.
Less understood dimensions like blade thickness, front groove depth, eye shape, and scarf angle also influence suitability for various fabrics. For example, needles with narrower blades minimize fabric hole size.Deeper front grooves accommodate heavier threads that would otherwise overflow the needle eye. Manufacturers offer hundreds of specialized needle types engineered for leather, vinyl, microfibers, and other fabrics, considering thickness, density, stretch, abrasiveness, and more material properties.
Thread
Like needles, threads interfacing with fabrics must also match their characteristics to create durable, quality seams. Thread itself comes in natural or synthetic forms, from sturdy denim thread for jeans to fine silks for couture detail work.
Consider fiber type, weight, twist, waxing/glazing, and other parameters when selecting thread. Lightweight, smooth threads prevent seam tension and slip through fabrics easily, while heavy-duty options stand up to high-speed and tension sewing machines without breaking. Match thread weight to fabric weight and needle size for best functionality.
Thread twist direction also affects seam integrity and strength. Generally, natural fibers and delicate synthetics use a z twist, while industrial polyesters and nylons twist to the right. Understanding these distinctions allows for troubleshooting issues like poor stitch formation, uneven tensions, fraying, breakage, or machine jams.
Importance of fabric-needle-thread relationship analysis
Rather than memorizing needle or thread details alone, focus on their interrelationships with fabrics for ideal stitch creation. Consider thread and fabric characteristics, then select the best intermediate needle size, point style, and dimensions.
1.Before starting, please firstly check whether the rated input electric currant and voltage match parameters required of the machine. The standard configuration electric current of the machine is 15A and the standard wiring method is triphase four-wire system, which are triphase L1-(Ay phase, L2-fig] phase and L3-(C) phase- And four-wire refers to three lines and an N line( referred to the zero line) of the normal electric current through the machine, which does not include the normal operating electric current PP line ground line)
2.Whether the power switch is turned on before checking compressed air, the air ,filter regulator combine#ion on the table has reached the specified pressure (0.5MPa-0.7MPa) and there is water in the filter cup or not(Moisture in tom- pressed air can damage the cylinder or reduce cylinder's life)
3.When non-continuous use, before starting please check the machine of the main power cables exposed, trachea, trip switches etc. to see whether they have detachment or breakage.
4.When non-continuous use, before starting please check each operation switches and knobs to see whether they can work and have a w.II flexibility, whether these is some change in the parameters of the inverter and electro-optical positioning meets the production needs or not.
5.Please do daily oiling to all functioning parts of the sewing machine before operating it. The main wear parts ailing once every two hours and sewing machine oil tank filled once every two weeks.
6.The machine's control system is controlled by PLC+Inverter+Touch Screen+Laser Sensor. In a particular environment, such as temperature is too low}below 10 degrees Celsius) or air is too wet, there will be electronic condensation in the machine,so please preheat it for 20-30 minutes.
7.Please check whether the fabric matches sewing thread. Using polyester filament yarn when the machine requires low temperature. When sewing high temperature fabric, the high temperature yarn requires fewer joint or no joint.
8.In order to prolong machine's life, please don't use it before running it at a low speed for 5-14 minutes each time, reacceleration in normal operation conditions under well-ailed. if finding any unusual, stag the machine immediately and check it. Before troubleshooting, please do not start the machine.
9.Please select sewing machine needles which are suitable for the machine.
10.Before staffing the machine, you must open the needle cooling device.
How Do You Maintain a Sewing Machine
Lubricate frequently
(1) Before using a newly purchased sewing machine or a sewing machine that has not been used for a long time, wipe off the dirt, add 2 to 3 drops of oil to each operating part, and run it for a few minutes before sewing.
(2) Generally, add oil once every half month or a month; for daily use, add oil once every 3 days. Add 1 to 2 drops each time.
(3) Use special sewing machine oil, never use vegetable oil or low-quality machine oil.
(4) It is best to add oil after sewing to prevent the oil from contaminating the clothes. After refueling, run the car empty to allow the oil to seep into the parts.
(5) When you step on the sewing machine, if you feel exhausted or there is a strange noise under the frame, you should immediately add oil to the movable parts of the frame.
Use correctly
(1) The pedal speed should not be too fast, otherwise the parts will be damaged.
(2) Simple maintenance should always be carried out at ordinary times: use a small brush or cotton yarn to remove the dust around the machine head and feed teeth, and wipe the bobbin, shuttle bed ring, and shuttle bed.
(3) When not in use, raise the presser foot plate, remove the belt, hide the machine head in the table, or cover it with a cloth cover.
(4) Do not place hot or heavy objects such as hot water cups on the table, and do not contact with alcohol and other chemicals.
The sewing machine should be cleaned and lubricated frequently to ensure the normal operation of the machine.
