[0022] The embodiment of the present application provides an adjustment device for a chamfering belt 42, wherein the chamfering belt 42 is configured to chamfer a gypsum board, such as Figure 1-Figure 3 As shown, the adjusting device includes a moving assembly 10, and the moving assembly 10 is configured to move in a direction perpendicular to the length direction of the chamfered belt 42, Figure 1 The moving assembly 10 is configured to move in the left-right direction (the length direction of the chamfered belt 42 is along the direction perpendicular to the paper surface); wherein, The moving assembly 10 includes: a moving frame 11 and two rollers 12, wherein the two rollers 12 are rotatably mounted on the moving frame 11, wherein the rotating shafts of the rollers 12 are vertically arranged and the two rollers 12 are arranged along the length direction of the chamfered belt 42, so that the chamfered belt 42 passes vertically between the two rollers 12.

[0023] When adjusting the chamfer belt 42, the driving moving component 10 is moved inward or outward in a direction perpendicular to the length direction of the chamfer belt 42, and the two rollers 12 can move the chamfer belt 42 inward or outward, so that the chamfer belt 42 can be adjusted, thereby adjusting the chamfer size of the gypsum board to be processed.

[0024] The chamfering belt 42 is usually arranged to run horizontally at the part where the gypsum board is chamfered. When the chamfering belt 42 runs through the two rollers 12, the chamfering belt 42 is twisted to stand upright. Figure 2 and Figure 3The state shown. In this way, the two surfaces of the chamfering belt 42 (the wedge-shaped surface for chamfering the gypsum board and the bottom surface opposite to the wedge-shaped surface) contact the two rollers 12. The two surfaces contact the rollers 12, and the contact area is large. The chamfering belt 42 can drive the rollers 12 to rotate during its operation, so that the friction between the chamfering belt 42 and the rollers 12 is small, and the surface of the chamfering belt 42 with a larger area fits the rollers 12, which is conducive to improving the stability of the operation of the chamfering belt 42, thereby improving the chamfering quality of the gypsum board. Among them, the horizontal operation of the chamfering belt 42 described in this application means that the bottom surface of the chamfering belt 42 that is away from the wedge-shaped surface is in a horizontal state, and when the chamfering belt 42 passes through the two rollers 12, the bottom surface is twisted to stand upright.

[0025] In some current embodiments, the chamfered belt runs horizontally between two rollers for adjustment. In this way, the spacing between the two rollers needs to be set according to the width of the chamfered belt. If it is set too wide, the chamfered belt cannot drive the roller to rotate. If it is too narrow, the chamfered belt will not run smoothly between the two rollers. In addition, the two sides of the chamfered belt are in contact with the two rollers, and the contact area is small. The two side edges of the chamfered belt cannot drive the roller 12 to rotate, so that the two side edges of the chamfered belt and the roller 12 have greater friction. The solution provided by the present application effectively solves the problem of the chamfered belt running horizontally between the two rollers.
