[0003] In the prior art, there are still certain deficiencies in the use of the hot pressing and laminating device for corrugated cardboard. Traditional corrugated cardboard is usually laminated by multiple layers of paper through a roller pressing method. When pressing a relatively thick corrugated cardboard, when the corrugated cardboard contacts the roller, due to the rotating force, the upper and lower cardboard will shift, resulting in uneven hot pressing and lamination of the corrugated cardboard, affecting the quality of the corrugated cardboard lamination. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hot pressing and laminating device for corrugated cardboard to solve the problem that traditional corrugated cardboard is usually laminated by multiple layers of paper through a roller pressing method.

Above the inner side of the corrugated paper laminating positioning rack, a fixed shaft sleeve is arranged. A connecting rotating shaft is arranged inside the fixed shaft sleeve. Angle limiting rods are arranged on both sides of the connecting rotating shaft. A reinforcing strut is arranged inside the angle limiting rods. The outer side of the angle limiting rods is connected to a bracket. A roller pressing cylinder is arranged at the lower end inside the bracket. A fixed-point rolling wheel is arranged above the inner side of the guide plate.

[0006] In a further embodiment, an angle limiting groove is arranged at the position of the lower left side inside the fixed shaft sleeve, and the angle limiting rod is slidably connected with the angle limiting groove, and the angle limiting rod is welded to the connecting rotating shaft.

[0007] In a further embodiment, the top end of the bracket is slidably connected to the outside of the fixed bushing, and the fixed bushing is welded to the corrugated paper fitting bracket.

[0008] In a further embodiment, the bracket is provided with an inclined structure, and the rolling cylinder is rotatably connected to the bracket.

[0009] In a further embodiment, the fixed-point rolling wheel is connected to the guide plate through a reinforcement seat. The reinforcement seat is welded to the guide plate, and the fixed-point rolling wheel is rotatably connected to the reinforcement seat.

[0010] In a further embodiment, the guide plate is connected to the main body of the corrugated paper hot-pressing and laminating machine through mounting foot pieces, and the mounting foot pieces are fixedly connected to the main body of the corrugated paper hot-pressing and laminating machine through inner hexagon fixing bolts.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In this utility model, the rolling cylinder is provided with an up-and-down adjustable structure. Since the rolling cylinder is relatively light in weight, it can be lifted upward by means of the force of corrugated paper transportation to roll and position the position where the corrugated paper is laminated, avoiding the deviation of the position where the corrugated paper is laminated, making the lamination neater and more reliable. And an angle limit groove is provided at the lower oblique position inside the fixed bushing. Through the angle limit groove, the range of up-and-down adjustment of the rolling cylinder can be limited, so that the rolling cylinder has a certain elasticity during the rolling process, increasing the stability of the pressing.
