How to use and maintain a sewing machine?

The dehydrator tells you: to buy a new sewing machine, you should use kerosene or stepson oil to scrub the anti-embroidery oil on it before use. A trade-friendly fade machine often has problems such as interrupted pressing, skipping pressing, and injection when it is first used.

In order to avoid these problems, the needle should be flat, the pinhole should be smooth, and the needle, Russian and cloth should be properly matched. In the sugar elbow, pay attention to the weak joints of the upper jaw tightness. Adjust the strength of the heart to hang the spindle, to the shuttle can use the self-help to swing down when it is appropriate.

Then according to the loose joints of the lower money, so that the upper pinching can not float and towel covers.

In addition, it is also necessary to pay attention to the pressure of the two presser feet on the cloth, generally the pressure on the thick material should be large, and the pressure on the thin material should be small, so as to prevent the duplication of money and the fabric from moving forward. In terms of maintenance of road planning machines, the child should remove the city head, city wool and dust accumulated on the shuttle bed track and cloth feeding teeth in time to prevent the parts from wearing out too quickly and the cloth feeding teeth touching the correction plate to affect the regulations. When installing the shuttle moon circle after cleaning, be sure to attach the minions to the moon sleepy beads to avoid injections and strong jumps.

At the same time, it should also be dipped in the machine to refuel, in addition to injecting according to each oil hole, but also to open the external plate and drop the front face, and refuel the internal operation part of the machine. The commonly used stare machine should be injected once a day after use, and it is best to use a thin bloom at the front of one or two pus, and the round can not be used with handle oil. After the oil is filled, the machine is divided into two parts, so that the oil is dispersed everywhere.

1. Newly bought or long-term sewing machines should be wiped off the dirt before use, and then 2 3 drops of oil should be added to each running part, and after a few minutes of idling, sewing again.

4. Special sewing machine oil should be used, and vegetable oil or inferior engine oil must not be used.

2. Correct use:

1. The pedal speed should not be too fast, otherwise the machine will be damaged.

2. Simple maintenance should be carried out frequently: use a small brush or cotton yarn to remove the dust around the machine head and cloth teeth, and wipe the bobbin core, shuttle bed ring and shuttle bed.

3. When not in use, lift the presser foot plate, remove the belt, hide the machine head in the platen, or cover it with a cloth cover.

4. Do not put hot water cups and other overheated or heavy things on the tabletop, nor can you touch alcohol, banana water and other chemicals.

I want to find a master to repair it.

Machine head maintenance The conditions for machine head maintenance are similar to those of a platen, but it is also necessary to prevent corrosion. The head and the upper wheel should not be wrapped with cloth strips or plastic cloth to prevent paint stripping or plating blistering and peeling. Sweat is very corrosive to machine parts, each time it is used, first wipe the sweat stains on the handle with a clean cloth, and then add a little oil with a soft cloth, respectively, wipe the center cover, swing shuttle, needle rod, upper wheel and other parts once, which can not only remove sweat traces, but also make the above-mentioned parts coated with a layer of oil film to play a protective role.

Volatile gases such as gas and pesticides have a serious corrosive effect on sewing machines, and should be kept away from these gases when stored.

Maintenance 1. Analysis of wrinkling of sewing material: broken tip of the needle, excessive tension of the bottom line, improper adjustment of the differential mechanism. Solution:

Replace the needle, loosen the bobbin spring screw, and readjust the differential mechanism. 2. Analysis of lattice marks formed by "gnawing" under the sewing material: the tip of the feeding tooth is too sharp and the pressure of the presser foot is too great.

Treatment method: You can use oil stone to grind the tip of the tooth and loosen the pressure regulating screw of the presser foot. 3. There are thread hairs under the sewing material, and there is a sound analysis of interrupting the fiber during sewing

The needle is broken or too blunt. Solution: Replace the needle with a new one.

4. Analysis of stagnation of sewing materials: the feeding teeth are too low and the pressure of the presser foot is too large. Solution:

Raise the feeding teeth and tighten the pressure adjusting screws.

The seam is backward and cannot be sewn analysis: the feeding cam is displaced. Solution:

Adjust the position of the feed cam. Analysis of irregular diagonal stitching: the cloth feeding tooth is crooked or the cloth feeding tooth screw is loose.

Solution: Correct the feeding teeth and tighten the feeding screws. Analysis of the rotation and stagnation of the machine head in the operation of sewing machine maintenance:

Wrong lubricating oil, especially vegetable oil; There is too much dirt in the shuttle bed; The connecting rod screws and taper screws are overloaded. Treatment: After rinsing with kerosene, refill the sewing oil; cleaning shuttle bed; Loosen the screws to ensure their clearance.

First of all, you need to choose the needle for your sewing machine, which can generally be decided according to the thickness of your fabric and the thickness of the thread.

When using the sewing machine, we place the clothes and fabrics that need to be sewn at the sewing opening under the needle, and then remember to put down the pressing plate, and the pressing plate should be aligned with the place that needs to be sewn. So that the sewing will not be crooked.

The position of the needle tip is shown in the figure below, after the thread is threaded, you can first pull it out with your hand to pull the thread out a little more to prevent the thread from falling out of the needle hole.

Then we can turn the hand crank with our hands and at the same time press the pedal below with our feet under our feet, and the sewing machine will start working. When you want to stop, you can also slowly stabilize the movement under your feet.

1. Select the needle of the sewing machine, and select it according to the fabric and thickness to be sewn.

2. According to the size of the stitches sewn, you need to adjust the position first, prepare the bottom line, that is, wear the bottom line on the machine with a lock cylinder to wrap the bottom line.

3. Wrap the bottom line and disassemble the fiber, use your left hand to take out the lock cylinder sleeve with the lock cylinder directly below the damaged jujube sewing machine plate, install the wrapped lock core thread, and pull the thread head out of the lock hole.

4. Put the lock sleeve of the lock cylinder back to its original position, install the back cover on the pressure plate, install the upper line, pull the thread, carefully thread the thread step by step, pass the thread through the pinhole, pull the thread with the left hand, turn the right first wheel with the right hand, turn the needle to the bottom and then lift it, and the bottom line is pulled out. Put the upper and lower threads back, then put the fabric you need in the middle of the pressure plate, remove the presser foot, press the cloth, start to turn the handwheel while pedaling the machine, and the sewn fabric will go backwards.
