Film coating machine for two-sided automatic register

Abstract

The invention relates to a film coating machine, in particular to a two-sided automatic plate-alignment film coating machine, which is provided with a basic cloth delivery-furl mechanism, a first basic material delivery-furl mechanism, a first composite mechanism, a second basic material delivery-furl mechanism, a second composite mechanism, a first color mark sensor, a second color mark sensor, a processor, a servo controller, and a servo motor; the second basic material delivery-furl mechanism is provided with a second basic material delivery-furl shaft, a second pressing roll, and a second basic material guiding roll which are driven by a second basic material delivery-furl motor; the servo motor drives the second basic material guiding roll; the processor is connected with the servo controller; and the servo controller is connected with the servo motor. The film coating machine has the automatic plate-alignment function of two-sided design, and the delivery-furl composite speed is rapid, the productivity effect is high, even though the basic material adopts an OPP film with very thin thickness, the highest delivery-furl composite speed of the OPP film can reach 80 meters per minute, the relative displacement of the color mark combined on the OPP films of the two sides of the same plastic braided cloth can be controlled within 3 mm.

Description

technical field [0001] The invention relates to a film coating machine, in particular to a double-sided automatic plate-aligning film coating machine. Background technique [0002] In order to improve the sealing performance of plastic woven bags, the existing technology adopts a layer of polypropylene film (OPP film), paper or aluminum foil on the surface of plastic woven cloth, and then makes plastic woven bags; Patterns and characters are printed on the surface of film, paper or aluminum foil. In order to achieve higher production efficiency in the prior art, patterns and characters are first printed on the surface of OPP film, paper or aluminum foil, and then compounded with plastic woven cloth. When patterns are required on both sides of the woven bag, the patterns printed on both sides are usually required to be aligned. If the patterns on both sides are not aligned and the patterns on both sides are offset, defective products will appear. In particular, the thickness...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to solve the technical problem that the existing film coating machine cannot realize the automatic plate alignment of double-sided patterns. The present invention provides a film coating machine with double-sided automatic plate alignment, which can automatically control the The displacement of the pattern on both sides is within the allowable range
