Knowledge Of Figures In Sewing Machine Models

　　 1. In the sewing machine number, the first group numbers represent the users.

　　 Sewing machine The main bodies and the stitches are the same, but the code of sewing equipment performance is different. Those who meet one of the following requirements may change the first set of figures.

(1) when the speed of operation is different from 500r/min,

(2) sewing objects (leather, rubber, plastics, etc.) at different times;

(3) sewing performance (such as reverse feeding, automatic trimming, automatic trimming, etc.);

(4) other institutions (such as bevel gears, flat toothed belts, etc.) are significantly different at the same time.

From the above regulations, we can see that the first group in the model. number The change is conditional. Generally speaking, the larger the number of groups, the greater the improvement on the original basis. For example, the industrial sewing machine GC1 one 1 has a lot of improvement compared with that of GC8 1. The former speed is 3000r/min, and the oil line lubricates. The latter has a rotational speed of 4500r/min, automatic lubrication, needle roller bearings, lever type reversing feeding, etc.

　　 2. The second groups of digital representatives have improved sequence codes on the original basis.

Those who meet the following requirements can change the second sets of figures:

(1) there are obvious changes in appearance;

(2) to ensure the sensitivity of the machine after improving the parts and changing the specifications of the chassis. In the process of sewing, if a needle breaks, it is necessary to find a broken needle immediately. If the product is within the radius of 1.5 meters, the needle must be checked. For example, the number of the second groups should be changed if the gear dropping mechanism is added.

　　 Model There are certain conditions for the change of the second sets of figures. From the specific point of view, the rivet, zipper, thread and other excipients like jeans will be marked on an excipient card, and the guests will be strictly recognized according to the accessories card. The second set of digital changes, to achieve regular customer visits, to fill in the gaps, eliminate all the feedback information affecting the corporate image and brand, and learn from experience and lessons. The main machinery of the machine is unchanged, so the improvement is only limited to the appearance and general improvement of the machine.
