Label absorbing device of system for internally labeling injection mold

Abstract

The invention discloses a label absorbing device of a system for internally labeling an injection mold. The label absorbing device comprises a label absorbing jig, an electrostatic needle, electrostatic sponge, a vacuum generator, an electrostatic generator and an electric control system, wherein two vent grooves which are communicated with inner holes of the label absorbing jig are formed in the surface of the label absorbing jig; the label absorbing jig is vertically mounted at the front end of the mechanical arm of the label absorbing jig through a jig mounting plate; the electrostatic needle is mounted on the outer peripheral surface at the front part of the label absorbing jig; the vacuum generator is mounted on a side surface of the rear part of the mechanical arm of the label absorbing jig and is communicated with the vent grooves of the label absorbing jig through pipelines; the electrostatic generator is mounted on a side surface of the rear part of the mechanical arm of the label absorbing jig and is electrically connected with the electrostatic needle through a signal line; the electric control system is in signal connection with each of the vacuum generator and the electrostatic generator. By adopting the label absorbing device of a system for internally labeling the injection mold, a piece of label paper can be relatively and stably absorbed, and the precision of a label feeding position is greatly improved.

Description

technical field [0001] The invention relates to a label absorbing device of an injection mold in-mold labeling system. Background technique [0002] In-mold labeling has many applications in the field of daily chemicals and food industry. Especially in the dairy industry, the three-in-one function of in-mold labeling, including aesthetics, anti-counterfeiting protection and decoration, is also favored by many packaging companies. With the widespread use of the injection molding in-mold labeling process in China, due to its imperfect technology, the performance of the label suction device is not stable enough in actual production. When the label paper is sucked, the label paper is often skewed, dropped, empty and label paper. Phenomena such as not being able to attach to the exact position of the mold cavity directly lead to skewed labels, product deformation, and even no defective products such as label paper on the surface of the product, which reduces the product qualific...

With the widespread use of the injection molding in-mold labeling process in China, due to its imperfect technology, the performance of the label suction device is not stable enough in actual production. When the label paper is sucked, the label paper is often skewed, dropped, empty and label paper. Phenomena such as not being able to attach to the exact position of the mold cavity directly lead to skewed labels, product deformation, and even no defective products such as label paper on the surface of the product, which reduces the product qualification rate and affects the production efficiency of the enterprise. At the same time, the production enterprise needs to increase the quality inspection personnel to monitor the quality of the product from time to time, which will increase the labor cost of the enterprise
