Spreading machine is a kind of automatic equipment, whose appearance takes place of the processing technology that labors paste the adhesive strips, which can reduce the cost, improve the production efficiency, and make the strips quality and appearance more perfect, it gradually becomes an indispensable antomatic equipment. The spreading machines of many different brands use the same or similar process, they can be used in a very wide range, it is possible to use it in many industries such as antomobile door, motor case, tank shell, gear box, Filter shell, speaker bracket, automobile lamp, protection board plastic parts and any spare and accessory parts need to seal.
â…¡, How to change the crown proportion The crown proportion of the strip is decided by the nature of the rubber itself, for example, normally, the crown proportion is 2 to 1, then when we operate in a standard configuration, we get the ratio should be about 2 to 1, if we adjust the surface height between the spreading machine nozzle and the parts to be sreaded to about 3mm, and we get the crown proportion is 3 to 1.
â…¢, How to adjust the connection points of the strips When we spread a closed graph, it is easy to appear a phenomenon that is the connection point is not so good, the beginning point and the end point can not be connected or there is excessive glue at the connection point, which makes the whole apearance not so beautiful. There are many ways to adjust the joint, and it needs to combined with each gluing machine process characteristics to adjust. In general, we adjust it by adjusting joint position and start over speed.
â…£, How to ensure the stips quality-----ratio test It is the most important to ensure the quality consistency of mass production, so we have to do a ratio testing before we producing to make sure the adhesive strips quality. The ratio testing is to check whether the feeding quantity of A and B rubber is correct. It should be set according to the data improved by the suppliers for the specific proportion of A and B, and the testing result is according to the technical parameters, within the reasonable error range, it can be regarded as the correct ratio. On the basis of ensuring the correct ratio, the users can produce massly.

Here, I introduce some points to use the spreading machine. Just set Huagong Innovation (Dalian) Technology Co.,Ltd as an example, I introduce how to handle these common problems. First, how to change the width and height of the strips The first one method to change the width: to keep the flow invariable, and change the processing speed. Another is :to keep the speed stable and to change the flow.
