Abstract

The utility model discloses an in-mold labeling color-printing film inserting device which comprises a molding mould made of plastic products and a mechanical arm operated by a computer program, wherein, a die head used for absorbing the color-printing film is connected at the tail end of the mechanical arm, the die head moves downwards to be collided with two film winding plates, the film winding plates are spread to cause the color-printing films on the film winding plates to be circularly wound and to cover the die head, the die head is energized with static electricity, the color-printing films are firmly absorbed on the die head, the mechanical arm moves and rotates, then the die head with the color-printing films is placed in a mould cavity of the molding mould, and when the die head is not energized with static electricity, an electrostatic generator connected with the mould cavity of the molding mould starts to work. Therefore, the color-printing films are absorbed in the mould cavity of the molding mould, after the mechanical arm is moved away, the injection molding machine carries out mould-closing injection molding production, the plastic products integrally molded by in-mold labeling and printing can be manufactured, the quality of the plastic products is improved, the adsorption of the electrostatic generator is more stable, the defective rate is reduced and the production efficiency is improved.

Description

The color printing film imbedding device of in-mold label

Technical field

The utility model relates to the in-mold label device, specifically is meant a kind of color printing film imbedding device of in-mold label of full-automation.

Background technology

Plasthetics, for the surface has splendid decorative aesthetics, handle with serigraphy, heat-transferring printing paper transfer printing or in the in-mold label mode on the plasthetics surface in the capital, wherein ideal in the in-mold label mode, the texture of plasthetics picture on surface is best, and fugitive color or come off does not meet the requirement of food-grade GMP most.

At present, the method that in-mold label is arranged that is retrieved, be to be connected with holder by a mechanical arm, has the label pusher on the holder, label is placed in the slot tag on the label pusher, by mechanical arm the label pusher is delivered to the mould place, the push rod in the label pusher is sent into label in the mould again, realizes the whole process of whole in-mold label.In this process, label adopts low weight thin-film material usually, color printing film for example, when the push rod of label pusher veers away label, label sometimes can be put askew causing and tilt, and can only hold a label in the slot tag, needs manually to add the label in each slot tag after one time decals is finished, inconvenience very greatly reduces efficient.

The utility model content

At the defective that exists in the technique scheme, the purpose of this utility model is to provide a kind of color printing film imbedding device of in-mold label of full-automation, and is more automatic and more accurate in the building-up process of color printing film and plastic products.

For achieving the above object, be achieved by the following technical solution:

The color printing film imbedding device of in-mold label, include the mould of plastic products and the mechanical arm of controlling by computer program, it is characterized in that: the terminal of mechanical arm is connected with the die head that is used for adsorbing the color printing film, die head is connected with electrostatic generator, board is provided with puts film frame and volume film mechanism, the board of putting under the film frame is provided with the sucker that is used for drawing the color printing film, sucker is transported to volume film mechanism by two balanced power pull bars drives with the color printing film after taking off the color printing film, described volume film mechanism is the volume templates that are provided with two fan band flexible members on board, and the mould die cavity is connected with electrostatic generator.

The described film frame of putting includes several backstays, the color printing film is placed in the device that backstay surrounds, the lower end of backstay is many annulus dentalation, the film frame of putting of color printing film one side is provided with gas blow pipe, what gas blow pipe was aimed at is the bottom position of color printing film, by the action that matches with compressed air in the gas blow pipe of many annulus dentalation, last that is easy to make the color printing film separated.

Described gas blow pipe is the type of twitching one's mouth.

Adopt technique scheme, the utlity model has following marked improvement:

1, the utility model adsorbs the color printing film by the end die that has electrostatic generator on the mechanical arm, after mechanical arm moves into place, die head moves down and touches two fan volume templates, the volume lamina membranacea is opened to take advantage of a situation the volume of the color printing film on it circle is wrapped die head, at this moment, the electrostatic generator work that die head connected produces static, firmly be adsorbed on the color printing film on the die head, the die head that mechanical arm moves after the rotation wounded die is placed in the die cavity of mould, electrostatic generator on the die head quits work at this moment, the electrostatic generator that mold cavity connects is started working, therefore the color printing film is just by adsorbed in the mold cavity, after mechanical arm was removed, injection machine began mold-closing injection production, can make and paste the integrated plastic products of printed film in the mould, improved the quality of plastic products, electrostatic generator absorption is more firm, reduces defect rate, enhances productivity.

2, the utility model can be drawn by gas blow pipe a folded color printing film and separate conveying with beneath sucker, can reduce cost of labor, increases work efficiency.
