Who can tell me how to adjust the roller seal defects?
Such as material, hardness, etc., especially relatively small tank diameter (such as 202 diameter cans). If the material of the tinplate is thin and the hardness is large, it will be more difficult to ask for it. Because in this case, the material in the double curling process will be less plastic, but the wrinkles will be larger.
In the sealing device, the roll sealing roller, the upper pressure head tray, usually referred to as sealing three elements. The correct groove shape of the roller, the reasonable position of the head and the proper driving force of the tray support are the necessary conditions to ensure the normal roll sealing. (see Fig. 1) it is easy to see that the three elements of the seal are the basic components of the sealing device and are also a fundamental factor affecting the double hemming.
The sealing process of hxa tank by double seam operation completed. Double seam method refers to two different groove shape of seaming rolls, through two feed motion sequence, the tank body and the tank cover with lid, crochet and cans, flanging hook tightly, so as to achieve the purpose of sealing method. Simply, that is the first edge hook, two edge compression molding.
