Description

Multifunctional in-mold labeling cup making production line

Technical Field

The invention relates to the technical field of cup making technology and plastic in-mold labeling, in particular to a multifunctional in-mold labeling cup making production line.

Background

In the prior art, the first step of the production process of the thermoformed container by the air-compression thermoforming machine is to produce the plastic container by heating the plastic sheet to be softened by the air-compression thermoforming machine and pulling up the positive air-compression forming punch shear in the forming mold. However, for many thermoformed containers (including cups, bowls, boxes and their covers) and many thermoformed containers and covers of different shapes in rows, labels requiring commodity information are usually printed on the surface of the thermoformed containers by a curved surface printing machine, but the curved surface printing process is characterized in that after a plurality of colors are sequentially cured without single color, a multicolor convex plate is used to transfer the characters and patterns onto the surface of the containers at one time, so the printing effect is not as beautiful as gravure printing. Besides curved surface printing, there are also several methods for completing text and pattern labeling on the appearance of a container or a cover, but all of the methods have serious defects of high production efficiency, high material labor cost, low grade and the like, and in addition, the various printing or labeling processes are required to be completed through separate production equipment, so that the whole production process is complicated, complex and low in efficiency and is not suitable for continuous automatic production of a thermoforming machine.

At present, there is an In-Mold Labeling (In Mold Labeling) mainly applied to blow molding and injection molding, which can be called In-Mold Labeling (In Mold Labeling), the technique is to put a printed and hot-pressed film label into a Mold, and melt the film label and the outer wall surface of a blow molding piece or an injection molding piece into a whole under the action of high temperature and high pressure In the Mold, so that the film label and the blow molding piece or the injection molding piece can complete hot melt adhesion at one time. The technology, especially the technology of the labeling equipment in the injection mould is mature and assists in promoting the development of the industry, and simultaneously, the grade of the packaging container is improved. However, the material weight and price of the injection molding container are higher than those of the air-compression thermal forming container, the production speed of the injection molding container cannot be compared with that of an air-compression thermal forming cup making machine (namely a cup making machine), particularly, a set of injection molding mold matched with an in-mold labeling mold and related configuration of each different mold which must be replaced are dozens of thousands of yuan, and the injection molding processing period and the debugging period seriously affect the supply of goods. At present, although few manufacturers in developed countries have research and development production internationally, the machine has certain limitation on container shapes and cannot be used in multiple functions, particularly, covers and irregular containers with diameters larger than the height cannot be used for conveying bags, and equipment manufacturers of the type including use manufacturers or blank equipment manufacturers at home.

In the prior art, the labeling machine for labeling the side wall of the container and the labeling machine for labeling the bottom or the bottom and the side of the container are two different machines, the labeling machine for labeling the side wall of the container can only apply a strip-shaped or arc-shaped label to the outer surface of the side wall of the container, the labeling machine for labeling the bottom or the bottom and the side of the container can only apply a piece of label to the bottom of the container directly or apply a part of the label corresponding to the bottom of the container, and the part of the label corresponding to the side wall of the container is folded and applied to the side wall of the container. Thus, if the factory needs to perform labeling in the above two ways, more than two labeling machines must be provided, which is very costly.

Therefore, it is important to develop an in-mold label and transfer integrated multifunctional production line for in-mold labels that is not limited by various shapes and has integrated design of functions, such as multi-functional in-mold labeling and transferring, aiming at the problems in the prior art and the situation that the living standard of people is continuously improved and the requirement for the market is higher and higher, and the prior art needs to be improved and improved or upgraded and updated.
