Color printing film imbedding device of in-mold label

Abstract

The invention discloses a device for placing an in-die labeling color printing film, which comprises a shaping die provided with a plastic product and a mechanical arm controlled by computer programs. One terminal of the mechanical arm is connected with a die head for adsorbing the color printing film, the die head moves downwards to touch two roll templates, then the roll templates are opened to roll the color printing film on the roll templates and wrap the die head, the die head is powered with static electricity to adsorb the color printing film to the die head firmly, the mechanical arm after being moved and rotated puts the die head with the color printing film into a die cavity of the shaping die, then the die head is cut off the static electricity, and an electrostatic generator connected with the die cavity of the die begins working, so the color printing film is adsorbed into the die cavity of the die; and after the mechanical arm is moved away, an injection molding machine begins production of matched dies and injection molding. The device can manufacture an integrally formed plastic product of in-die labeling printing films, improves quality of the plastic product, reduces defective rate because the adsorption of the electrostatic generator is comparatively stable, and improves production efficiency.

Description

technical field [0001] The invention relates to an in-mold labeling device, in particular to a fully automatic in-mold labeling color printing film insertion device. Background technique [0002] Plastic products, in order to have excellent decorative aesthetics on the surface, will be processed on the surface of plastic products by screen printing, thermal transfer paper transfer, or in-mold labeling. Among them, in-mold labeling is the most ideal. The texture of the surface pattern of the product is the best, and it is not easy to fade or fall off, which best meets the requirements of food-grade GMP. [0003] At present, the retrieved method of in-mold labeling is that a mechanical arm is connected with a fixed seat, and the fixed seat has a label pusher, and the label is placed in the label groove on the label pusher, and the label pusher is pushed by the mechanical arm Send it to the mold, and the push rod in the label pusher will send the label into the mold to realize...

AI Technical Summary

Problems solved by technology

In this process, the label is usually made of a relatively light film material, such as a color printing film. When the push rod of the label pusher delivers the label, the label is sometimes skewed and tilted, and only one label can be accommodated in the label slot. After the labeling is completed, the labels in each label slot need to be added manually, which is very inconvenient and greatly reduces the efficiency
