The glue spreader is a kind of intelligent equipment. Its appearance has replaced the processing technology of sticking the glue strip by the workers all the time. It can reduce the cost, improve the production efficiency, improve the quality of the glue strip, and make the appearance more smooth. It is the necessary link for modern industry to transfer from manual operation to automatic operation. The applicator has a wide range of applications, all walks of life have the possibility of its application. Here for you to introduce a few tips, for the use of a variety of gelatinizer, introduce how to deal with these common problems in production.
1. How to change the width and height of adhesive strip
Change the width method 1: change the processing speed without changing the glue flow.
Change the width method 2: speed unchanged, change the glue flow.
2. Width height ratio of rubber strip
The width to height ratio of the adhesive strip is determined by the characteristics of the glue itself. For example, if the width to height ratio of the adhesive strip provided in the TDS of glue is 2:1, the width to height ratio obtained after the standard gluing operation should be about 2:1 (1.8:1-2:1).
3. How to adjust the rubber strip joint
When painting closed figures (such as circle, square, rectangle, etc.), the rubber strip is easy to have poor joint, the connection between the start point and the end point is not good, or the connection between the start point and the end point overlaps too much, resulting in the unsightly joint of the rubber strip. There are many ways to adjust the joint, and it needs to be adjusted in combination with the process characteristics of each glue applicator. It is usually through adjusting the position of the joint (such as the position of the joint at the corner), the speed when adjusting the speed and the closing time to achieve the effect of beautiful joint.
4. How to ensure the quality of adhesive strip – proportion test
The consistency of strip quality is very important to product quality in mass production. In order to ensure the consistency of strip, the proportion test should be carried out before production. The purpose of the proportional test is to check whether the single output of glue a and B from the glue valve is consistent and accurate. The specific proportion of glue a and glue B shall be set according to the TDS data provided by the glue supplier, and the test results shall also be compared with the technical parameter table (such as hardness and density), which can be considered as the accurate glue injection proportion within the reasonable error. After ensuring the accurate proportion of glue a and B, users can carry out mass production.
