When the cardboard passes through the hot pressing mechanism, the contraction and reset of the first telescopic spring can ensure that the clamping plate applies appropriate pressure to the cardboard, which helps to maintain the stability of the cardboard. The design of the ball bearing allows the cardboard to form rolling friction with the extrusion plate when moving, rather than sliding friction, which can reduce friction resistance and reduce the possible jamming or offset of the cardboard during movement, so as to squeeze and limit the cardboard, greatly reduce the probability of wrinkles or offsets in the cardboard, improve the quality of cardboard forming, and bring convenience to the staff when using it. The movement of the moving block drives the movement of the pointer, so as to achieve the effect of accurately adjusting the position of the moving plate, and meet the hot pressing effect of cardboards of various thicknesses.

[0017] 2. By engaging the installation box and the workbench together, and then pulling the U-shaped rod to drive the pull plate to move, the movement of the pull plate drives the slide plate to slide on the outside of the installation frame. At this time, the slide plate squeezes the second telescopic spring, and the U-shaped rod is loosened, and then the second telescopic spring is reset, so that the insertion rod and the installation box are engaged and fixed, thereby achieving the effect of quickly installing and disassembling the installation box, which is convenient for subsequent staff to inspect and repair it, and brings convenience to the staff when using it.

[0030] Working principle: Before using this anti-wrinkle composite corrugated paperboard production hot pressing device, it is necessary to first check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6 As shown, when the moving cardboard approaches the hot pressing mechanism 101, the staff puts the two sides of the cardboard between the fixed plate 204 and the movable plate 205, and pulls the two sets of squeezing plates 206. At this time, the squeezing rod 209 squeezes the first telescopic spring 210, and then the staff rotates the screw 202 to drive the movement of the moving block 203. The movement of the moving block 203 drives the movable plate 205 close to the fixed plate 204. At this time, the ball 207 is rollingly connected with the cardboard, and then the squeezing plate 206 is released, and then the tension generated by the first telescopic spring 210, when the cardboard passes through the hot pressing mechanism 101, the contraction and reset of the first telescopic spring 210 can ensure that the clamping plate applies appropriate pressure to the cardboard, which helps to keep the cardboard stable. Qualitatively, the design of the ball bearing 207 allows the cardboard to form rolling friction with the extrusion plate 206 when moving, rather than sliding friction, which can reduce frictional resistance and reduce the possible jamming or deviation of the cardboard during movement, so that the cardboard can be squeezed and limited, greatly reducing the probability of wrinkles or deviations in the cardboard, improving the cardboard forming quality, and bringing convenience to the staff when using it. The movement of the moving block 203 drives the movement of the pointer 212, so that the position of the moving plate 205 can be accurately adjusted to meet the hot pressing effect of cardboards of various thicknesses, bringing convenience to the staff when using it. By locking and fixing the positioning block 215 with the socket 214, the adjusted position of the pointer 212 can be fixed and limited;

[0031] By engaging the installation box 201 and the workbench 1 together, and then pulling the U-shaped rod 302 to drive the pull plate 303 to move, the movement of the pull plate 303 drives the slide plate 305 to slide on the outside of the installation frame 301. At this time, the slide plate 305 squeezes the second telescopic spring 307, and by loosening the U-shaped rod 302, and then through the reset property of the second telescopic spring 307, the insertion rod 304 and the installation box 201 are engaged and fixed, so that the installation box 201 can be quickly installed and disassembled, which is convenient for subsequent staff to inspect and repair it, and brings convenience to the staff when using it.
