What are the refueling parts of the sewing machine? What is the knowledge of maintenance?

A computer needle or sewing machine should be fully oiled once in a day or a few days after it is used continuously. If it is refueled between uses, the machine should be idled to allow the oil to fully infiltrate and throw out excess oil, and then clean the head and table top with clean soft cloth. So as not to stain the seams. Then wear the thread to sew the rags, use the motion of the sewing thread to wipe off the excess oil, until there is no oil on the rags, and then make formal sewing.

The refueling parts of computer sewing machines are:

(1) The oil holes on the head, lubrication of the upper shaft and the connected parts of the upper shaft;

(2) the internal parts of the panel and the moving parts connected to them, the lubricating pins and pins and the parts connected to them;

(3) The movement of the machine's lower part is cleaned and less oil is added. The amount of refueling in each fuel hole and the refueling part does not need to be too much. 1-2 drops will do.

Second, maintain the computer needle car should also pay attention to the following points:

(1) After the work is completed, insert the machine needle into the needle hole plate, lift the pressure foot, and use the machine cover head to prevent dust from invading people.

(2) When starting work, the computer needle car should first check the main machine parts, how serious the step is, whether there is a special sound, whether the machine needle is normal, etc.. If an abnormal phenomenon is found, it should be promptly overhauled.

(3) After the machine has been in use for a long time, it must undergo a major overhaul. If more worn parts are found, new ones must be replaced in time.

What is the knowledge of maintenance of sewing machine of computer needle car?

Social development has brought a lot of convenience to our lives. When we make clothes and fabrics, we often use the upgraded version of the sewing machine-the computer needle car. This kind of equipment is very convenient to use. When we use it, we need to do good maintenance work. What is the maintenance knowledge of this equipment?

1, careful cleaning and cleaning to ensure that the parts of the computer needle car clean, to ensure the assembly of quality and extend the service life of the computer needle car. In particular, the shaft sleeve, bearings, oil pumps, and parts containing rotating and swinging accessories should be carefully cleaned. If various shaft components are not clean when assembled, light will cause the shaft sleeve to heat up over Gaohe's transmitted power moment. In serious cases, it will accelerate wear and tear due to debris, and serious faults such as "bite" will occur, affecting the overall performance of the machine.

(2) All computer needle parts and components which have been surface treated with paint, electroplating, etc. are fitted with adhesive surfaces(including holes, grooves, planes and screw holes). Therefore, prior to assembly, such parts and components must be subject to the technical requirements of the process; If the assembly does not meet the required technical requirements, the computer needle can not work properly. The incorrect position of parts and mechanisms also affects the performance of the computer needle truck.
