Description

A local film coating device for paper products

Technical Field

The utility model relates to the field of paper product processing equipment, in particular to a local film coating device for paper products.

Background technique

Paper product lamination is to cover a layer of plastic film on the surface of paper, and firmly bond the paper and plastic film together by hot pressing or cold pressing. Lamination can better protect the patterns or text printed on paper products. At present, most of the paper product lamination adopts the whole sheet lamination method, that is, the size of the plastic film is consistent with the size of the paper product, and the plastic film is covered on the entire surface of the paper product. For products where the entire paper is covered with printed patterns, there is no problem. However, in many cases, such as products such as packaging boxes with a large area, the area with printed patterns or words only occupies a part, and the other areas may not be a complete paper surface due to the box structure itself. In this case, the overall lamination is not reasonable. On the one hand, it will lead to an increase in cost, and on the other hand, it will also affect the subsequent use of the product.

The film coating mechanism 3 works by hot pressing film coating, and the film is pressed onto the paper product by a heated film pressing head.

Through the structure of this solution, the frame 2 is used as the bearing structure of the laminating mechanism 3, and the base 1 is used as the bearing structure of the paper product to be laminated. The base 1 is used to transport the paper product on the one hand, and on the other hand, it can meet the convenience of adjusting the position of the paper product by the staff to ensure the accuracy of the local laminating position. The position of the laminating mechanism 3 on the frame 2 is also adjusted to meet the needs of different sizes or laminating positions.

On the basis of the above-mentioned implementation scheme, the base 1 includes a stand as the main supporting structure, and the stand is a frame structure, which is fixedly arranged at the working position of the device. Two bottom slide rails 13 are symmetrically arranged on both sides of the lower part of the stand, and the bottom slide rails 13 are fixedly connected to the stand and are used as guide rails for the translation of the frame 2. The frame 2 includes two gantry frames, and the vertical parts on both sides of the gantry frames are retractable rods. The bottom ends of both sides of the gantry frames are respectively slidably connected to a bottom slide rail 13; the laminating mechanism 3 is slidably connected to the upper part of the gantry frame. Considering the stable support of the laminating mechanism 3, two gantry frames are arranged as the frame 2, and the laminating mechanism 3 is hung on the two gantry frames to obtain more stable support.

On the basis of the above embodiment, referring to FIG. 2 , the transmission assembly 11 includes a plurality of transmission rollers, and the transmission assembly 11 is formed by an array of transmission rollers, each of which includes a transmission shaft 111, a transmission plate 112 and a transmission block 113, and the transmission rollers of the transmission assembly 11 are arranged in parallel with the transmission shaft 111.

Considering that the size of the film laminating area is different, an adjustable film pressing frame 321 and film pressing guides 323 are provided. A mounting position is reserved on the film laminating frame 33 between the two film pressing guides 323, and the mounting position is used to place a film frame for film pressing. Taking into account that relying solely on the downward pressure of the film pressing head may cause the film supply to be disconnected, a hollow frame corresponding to the film pressing head is set as a film frame. The film frame includes two upper and lower frame structures. The film passes through the gap between the two frames. With the help of the film frame itself limiting the film and combining the downward pressure of the film pressing head, the film pressing head can cut the required part of the film from under the roll and hot-press it onto the paper product.
