[0002] Kraft paper is a tough, water-resistant packaging paper with a brownish-yellow color. It has a wide range of uses and is often used to make paper bags, envelopes, exercise books, record sleeves, files, and sandpaper. The main quality requirements are flexibility, strength, high burst resistance, and the ability to withstand large tension and pressure without breaking; kraft paper has high tensile strength and is available in single-gloss, double-gloss, striped, and plain colors. It is also used for packaging paper, envelopes, paper bags, and printing press drum linings.

[0003] At present, when performing composite molding operations on multiple layers of kraft paper, it is necessary to first composite the multiple layers of kraft paper coated with glue together, and then use a pre-pressing roller to pre-press the multiple layers of kraft paper. During the pre-pressing process, it can only ensure that the multiple layers of kraft paper are tightly attached together, but it cannot ensure that the glue is quickly cured and air-dried. At this time, an additional drying mechanism is required for drying, which will increase the steps of composite molding of multiple layers of kraft paper, thereby making the operation steps cumbersome and inconvenient. Therefore, it is necessary to design an efficient composite molding device for multiple layers of kraft paper. Utility Model Content

The output end of the first electric telescopic rod 14 is fixedly connected with the upper hot pressing plate 15. The upper hot pressing plate 15 is located just above the lower hot pressing plate 16. During operation, when the composited multi-layer kraft paper enters between the upper hot pressing plate 15 and the lower hot pressing plate 16, the first electric telescopic rod 14 drives the upper hot pressing plate 15 to move downward, and with the cooperation of the lower hot pressing plate 16, the multi-layer kraft paper can be hot-pressed and formed.

[0022] Furthermore, the lower end of the workbench 1 is fixedly connected to a third support plate 25, and the inner part of the third support plate 25 is rotatably connected to a winding roller 18, which is located at the lower right end of the hot pressing mechanism.

[0026] Working principle:

[0027] When in use, a layer of kraft paper enters between the multiple groups of pre-pressing rollers 10 and 11 along the first overlapping roller 3, and is wound on the circumferential surface of the winding roller 18 through the hot pressing mechanism and the guide roller 17. A layer of kraft paper is glued by the first glue roller 5 and then enters between the pre-pressing roller 10 and the pre-pressing roller 2 11 along the second overlapping roller 8 for pre-pressing and heating to form a double layer of kraft paper. A layer of kraft paper is glued by the second glue roller 6 and then enters between the pre-pressing roller 10 and the pre-pressing roller 2 11 along the third overlapping roller 9 to be pre-pressed and laminated with the previous double layer of kraft paper. Before lamination, the second electric telescopic rod 24 operates to drive the push plate 21 to move upward, and then drives the pre-pressing roller 2 11 to move upward under the cooperation of the ear plate 23 and the sliding block 22. At the same time, the spring 19 is compressed. At this time, the distance between the pre-pressing roller 2 11 and the pre-pressing roller 10 gradually increases, so it is convenient to put the kraft paper on the pre-pressing roller 1 0 and pre-pressing roller 2 11, when the multi-layer kraft paper is placed, the second electric telescopic rod 24 is controlled in the reverse direction to drive the push plate 21 to move downward, so that the push plate 21 gradually separates from the ear plate 23. At this time, the sliding block 22 drives the pre-pressing roller 2 11, and under the action of the spring 19 and its own gravity, it moves downward along the sliding rod 20, so that the pre-pressing roller 2 11 can be pressed more tightly on the kraft paper on the pre-pressing roller 10. At the same time, under the action of the heating rod 27, the pre-pressing roller 10 and the pre-pressing roller 2 11 can be heated to ensure that the glue between the multi-layer kraft paper is cured and dried faster, and to ensure that the composite kraft paper after overlapping has excellent bonding, so as to facilitate the subsequent multi-layer kraft paper and complete the composite molding work more efficiently. Then the multi-layer kraft paper directly enters the hot pressing mechanism for hot pressing operation, and then the kraft paper completes the efficient composite molding work, and finally the composite molded kraft paper is rolled up by the winding roller 18.
