How to choose a household embroidery machine?
What is a household embroidery machine? First of all, we need to know what an embroidery machine is. This machine is used for embroidery, which is what we call embroidery. Household embroidery machine is a kind of machinery and equipment used for embroidery at home, which is relatively simple to operate and belongs to computer and manual embroidery equipment. Nowadays, many people are interested in embroidery, but the time and difficulty of manual embroidery are relatively large. Below, let's take a look at how to choose a home embroidery machine and what is the principle of the home embroidery machine.
First, the main points of home embroidery machine purchase
1, machine precision, no precision, no beauty (minimum stitch length per stitch is 0.8mm).
2, software function, software function is not strong, pattern design level can not go up, so it is very important to choose software.
3, machine life, this is guaranteed by the life of parts, parts wear and age, first the accuracy drops, then the damage, parts interchangeability is poor, embroidery accuracy will inevitably be discounted, here, we strongly recommend-Lewanjoy brand embroidery machine, very easy to use and stable performance.
4. Price is not the key factor in choosing an embroidery machine. Never buy an embroidery machine on the basis of "money". The embroidery machine is an industrial product, and the processing cost determines the quality level of the machine. Don't consider how to repair the machine when it is broken. If it is broken, it must be repaired, and the maintenance quality cannot be poor. Artificially transferring the quality and service life of machines to manufacturers and even dealers, price indicators can sometimes be called "consumption traps", such as gimmicks in sales links such as discounts, discounts and concessions. Consumers are greedy for small profits and will be harmful.
Second, the principle of embroidery machine
First, the embroidery CAD software is used to make plates, and then the plates loaded with embroidery programs and patterns are put into computer disk drives respectively. Under the control of the programs, the computer changes the coordinate values of the patterns into electrical signals equivalent to the displacement of the stretched frame in X and Y directions, and sends them to the X, Y and Z single-chip microcomputer systems for motor speed-up and speed-down processing, and then outputs three-phase six-beat signals. The power amplifier box of the linear motor amplifies the power, and the red X and Y stepping motors drive the stretched frame to complete X.
At the same time, the Z stepping motor is driven, and the needle with motor moves up and down, so that embroidery can continue. Z stepping motor drives the transmission mechanism of the machine head to rotate through synchronous toothed belt, etc. The special mechanism of the machine head makes the lead mechanism and the needle head move up and down to puncture the fabric; The rotating shuttle in the crochet mechanism rotates, so that the upper thread bypasses the shuttle shell with the hidden bottom thread; The thread take-up mechanism moves, transports the upper thread, tightens the stitch and prepares the upper thread segment of the next stitch. X and Y stepping motors drive the silk frame and fabric to make plane motion through synchronous toothed belt and other mechanisms. Each stitch point to be embroidered on the fabric is sent to the needle for embroidery, and the speed of the needle moving up and down is coordinated with the moving direction, moving amount and moving speed of the tension frame, so that the upper thread and the bottom thread are twisted and a double-thread lock stitch is made on the fabric. When embroidery continues, computer embroidery of patterns is completed.
The above is the introduction of the purchasing skills and principles of household embroidery machines. The principle of home embroidery machine is very complicated, which is not easy for us to understand, because it is controlled by control program, and we only need to input the program into the computer to run the machine, but it is a little difficult for us to analyze and understand the structure inside. When we choose the brand of home embroidery machine, the brand of Lewanjoy has a long service life.
