As the preferred, the manipulator still includes operation regulating plate and erection column, the operation regulating plate adjust the location through the slide rail along the erection column, the handling frame carry out elasticity return and elastic component and operation regulating plate fixed through the elastic component.

A quick labeling method of an in-mold labeling device comprises the following steps:

the label sticking operation is combined with the blow molding process, the process of sticking labels after plastic products are molded is omitted, in the in-mold label sticking process, the labels which are printed and die-cut in advance are stacked in a single-sheet mode and placed in a label frame, sucking discs of a mechanical arm suck the labels one by one and move to a label sticking waiting position for waiting, on the other hand, the material temperature of a hollow molding machine is controlled within the range of 190 ℃ plus 170 ℃, the temperature of a mold is 18-25 ℃, the equipment mold frame finishes air blowing at an air blowing position, a mold opening signal is obtained by the mechanical arm along with the opening of the mold and enters a mold cavity to a set position, an operation long arm is opened, the labels are placed in the opened mold, the printing surface of the labels is inward, the labels are firmly adsorbed on the wall of the mold in the mode of vacuum negative pressure, after the mold is closed, the mold is moved to the mold entering position for mold closing, molten plastic resin enters the mold, the air pressure blow-up shaping by 6KG, air pressure blow-off resin makes the product wrap the label completely this moment, opens once more when the mould, and the plastic container shaping, label and container tie are as an organic whole, become the partly of shaping container, and about the label position and angle all can be adjusted about to reach perfect effect.

The biggest difference between the in-mold labeling and the traditional labeling is that the labeling mode is different, and the in-mold labeling is not carried out after the plastic container is completely molded. But the container forming is completed in one step. Because of different labeling modes, the process requirement for labeling in the die is high.

The invention relates to an in-mold labeling device and a rapid labeling method thereof, which can finish labeling by one-step molding and increase the firmness of labels.
