[0002] In the production process of composite wall coverings, two or more layers of wall coverings need to be laminated, and a hot press laminating machine is used for the lamination operation during lamination.

[0003] In the related art, reference can be made to the Chinese utility model patent with the authorization announcement number CN218966372U, which discloses a hot press laminating machine, including a workbench, a heating and laminating unit, and a cooling and collecting unit; a cooling and collecting unit is installed on the front side of the upper end of the workbench; the heating and laminating unit includes a protective cover, a U-shaped bracket, a fixing block, a second motor, a rotating shaft, a heating wire, a metal protective cover, and a moving clamping assembly. A protective cover is provided on the rear side of the upper end of the workbench. A vertical U-shaped bracket is provided on the front side of the left end of the protective cover. One end of the moving clamping assembly is connected to the upper and lower ends inside the U-shaped bracket. The other end of the moving clamping assembly is connected to the center of the upper end of the fixing block. A second motor is provided on the left side of the upper end of the fixing block. The tight combination during the lamination of two materials improves the hot pressing effect, and the cooling structure is relatively efficient, not easily causing residual glue to stick, and strengthening the mutual combination between materials.

[0004] When the hot press laminating machine is in use, the wall covering is prone to deviation, resulting in poor lamination effect of the wall covering. Usually, manual pulling is used for reset adjustment, and the adjustment operation is relatively inconvenient. Utility Model Content

[0005] In order to solve the problem that the wall covering deviates during the use of the hot press laminating machine and the manual pulling method for reset adjustment is inconvenient to operate, the present application provides a hot press laminating machine.

[0006] A hot press laminating machine provided by the present application adopts the following technical solution:

[0007] A hot press laminating machine includes a frame, on which an upper cloth roll and a lower cloth roll are rotatably installed. The wall covering is respectively wound around the upper cloth roll and the lower cloth roll. A heating box is arranged on the frame. A laminating roll is rotatably installed on the frame on one side of the heating box. There are two laminating rolls arranged vertically and horizontally. The wall covering is hot pressed between the two laminating rolls. A tensioning assembly is arranged on the frame, and the tensioning assembly is used for tensioning the wall covering. A deviation rectifying assembly is arranged on the frame on one side of the tensioning assembly. The deviation rectifying assembly includes a deviation rectifying roll and an adjusting member. The deviation rectifying roll is rotatably installed on the frame, and the adjusting member is arranged on the frame. The adjusting member is used for adjusting the position of the deviation rectifying roll.

[0008] By adopting the above technical solution, after the wall cloth on the upper cloth winding roller and the lower cloth winding roller is tensioned by the tensioning assembly, it is conveyed to the deviation rectifying roller. When the wall cloth is offset, the adjusting member adjusts the position of the deviation rectifying roller to drive the wall cloth to return to its position. The rectified wall cloth is conveyed to the heating box for heating. After heating, the wall cloth is compounded and then hot-pressed between the laminating rollers. The operation of rectifying the wall cloth is relatively convenient.

After passing through the deviation rectifying roller 61, it enters the heating box 2 and is heated by the first heating plate 71 and the second heating plate 72. The heated wall cloth is laminated and then hot-pressed and laminated by the laminating roller 3.

[0046] When the position of the wall cloth transportation deviates, the motor 621 drives the gear 622 to rotate. The gear 622 moves along the arc-shaped tooth groove 64 and then drives the limit block 63 to move. The limit block 63 drives the deviation rectifying roller 61 to deflect, and then drives the wall cloth on the deviation rectifying roller 61 to move back to the original position. At this time, the motor 621 drives the gear 622 to rotate until the limit block 63 returns to the original position, and the operation of wall cloth deviation rectification is relatively convenient.
