Description

Prevention facility of bending of heat panel

In order to protect the contents of printed matters, ID cards and the like, to prevent forgery, and to improve the appearance, a laminating method of forming a predetermined film layer on the surface of the contents is widely used. Accordingly, the demand for a laminating device is increasing.

The present invention relates to a hot plate bending prevention device of a laminating device, in particular perforating the holes in both ends of the plurality of hot plates symmetrical with each other at a predetermined interval and inserting the support pins in the holes to fix the hot plate to the support pins and the spring The present invention relates to a hot plate capable of maintaining elasticity and being capable of expanding without external pressure to both ends of the hot plate by a long hole during thermal expansion of the hot plate.

Referring to FIG. 1, a general laminating apparatus is symmetrical with a heating roller 3 for heating a film 2 laminated on the surface of the contents 1, and contacting the heated laminate film 2 with the contents 1. It consists of a hot plate apparatus composed of a plurality of hot plates 4a and 4b in the form of a plate, and a crimping roller 5 for crimping the contacted film 2 and the contents 1.

The laminate film 2 is heated by the heating roller 3 while advancing by the rotation of the rollers together with the contents 1 to generate an adhesive force, and the contents 1 between the hot plates 4a and 4b of the hot plate apparatus. ), It is pressed by the pressing roller 5 and laminated on the surface of the contents.

Referring to FIG. 2, a conventional hot plate device has a structure in which both end portions in the longitudinal direction of the hot plates 4a and 4b constituting the hot plate device are fixed to the support 12 by applying a screw 11. Since the screw holes formed in the hot plates 4a and 4b coincide with the dimensions of the screws, the hot plates 4a and 4b are completely fixed to the support 12.

The hot plates 4a and 4b are made of metal, and are expanded by heat generated in the heating apparatus during the laminating operation. In particular, the hot plates 4a and 4b have a high degree of expansion in the longitudinal direction. It is not completely absorbed by the expansion part because it is completely fixed to it. Therefore, when the laminating operation is continued for a long time, there is a problem in that the lamination operation cannot continue because the gap between the hot plates is extremely narrowed or blocked due to bending of the hot plates 4a and 4b in the longitudinal direction.

It is an object of the present invention to provide a warp preventing device for a hot plate of a laminating device that allows a laminate operation to last for a long time.

A laminate apparatus is disclosed that includes a hot plate device composed of a plurality of hot plates in a plate shape and a support body symmetrical to each other at predetermined intervals. The hot plate device is characterized in that for supporting the hot plate formed with a hole on the support by applying a support pin and a spring.

An embodiment of the present invention will be described in detail with reference to FIG. 3.

The hot plates 4a and 4b having the long holes 21 formed therein are divided into upper hot plates 4a and lower hot plates 4b according to their positions with respect to the support 12, and lower portions passing through the holes 21. Supported by the support 12 by the support pin 22, the hot plate (4a, 4b) is not fixed to the support. The hot plates 4a and 4b have holes 21 having a size larger than the cross-section of the body of the support pins 22 and 23 at positions where the support pins 22 and 23 pass, and the holes 21 It is an elliptical shape with a long diameter in the longitudinal direction of the hot plates 4a and 4b having a high degree of expansion.

When the support pins 22 and 23 are applied to support the hot plates 4a and 4b, there is considerable margin in the length direction of the hot plates 4a and 4b in the holes 21.

The lower support pin 22 is fixed to the support 12 and is inserted into the hole of the hot plate 4b, and an end of the lower support pin 22 of a predetermined length protrudes out of the hot plate 4b.

The upper support pin passes through the hole 21 of the upper hot plate 4a and is fixed to the lower hot plate 4b, and a spring 24 is inserted between the head of the upper support pin 23 and the hot plate 4a. The hot plate 4a elastically elastic to the spring 24 is stopped and fixed by interfering with the projecting end of the lower support pin 22.

When the hot plates 4a and 4b are supported by the support pins 22 and 23, the margins present in the holes of the hot plates 4a and 4b are absorbed by the expanded portion when the hot plates 4a and 4b are expanded by the heat of the heating apparatus. In particular, since the hole 21 has an elliptical shape having a long diameter in the longitudinal direction of the hot plates 4a and 4b, the expanded portion in the longitudinal direction of the hot plates 4a and 4b is absorbed. By the end of the support pin 22, the spacing of the hot plates 4a and 4b is kept constant, and the spring 24 prevents the fluctuations and positional fluctuations of the hot plates 4a and 4b so that Keep the interval constant.

Since the hot plates 4a and 4b are not fixed to the support 12 or the support pins 22 and 23, the holes 21 formed in the hot plates 4a and 4b are laminated by the hot plates 4a and 4b. Because the absorbed portion of the expansion of the hot plate does not cause warpage.

With the above configuration, the interval of the hot plates 4a and 4b is always kept constant regardless of the laminate working time, so that it is possible to continue the laminating work.

In the laminate apparatus according to the present invention, since the bending of the hot plate is prevented during the laminating operation by using the warpage preventing device of the hot plate, the productivity of the laminate can be improved by continuous work.
