Description

Technical Field

[0001] The present application relates to the technical field of gypsum board processing, for example, to a gypsum board cutting device. Background Art

[0002] At present, gypsum board often needs to be cut during production and processing to obtain suitable specifications and sizes. Related technology (publication number: CN218227300U) discloses a gypsum board cutting device for gypsum board production and processing, including a processing table, a first telescopic member, a second telescopic member, a first clamping mechanism, a second clamping mechanism and a cutter. The first telescopic member and the second telescopic member are respectively arranged on both sides of the top of the processing table. The first clamping mechanism and the second clamping mechanism are respectively arranged at the ends of the telescopic ends of the first telescopic member and the second telescopic member. The first clamping mechanism includes a first motor arranged at the telescopic end of the first telescopic member, and a first transmission block connected to the end of the output shaft of the first motor. The second clamping mechanism includes a second motor arranged at the telescopic end of the second telescopic member, and a second transmission block connected to the end of the output shaft of the second motor. The cutter is arranged at one end of the processing table. Among them, the first clamping mechanism and the second clamping mechanism are driven to move by the extension of the first telescopic member and the second telescopic member to clamp the gypsum board, and the clamped gypsum board can be driven to move by the rotation of the first clamping mechanism and the second clamping mechanism, and cut by the cutter.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The first clamping mechanism and the second clamping mechanism rotate to drive the clamped gypsum board to move, so that the gypsum board can be cut again, and there is no need to frequently remove and fix the clamped gypsum board. Since the first transmission block and the second transmission block are both cylindrical, the contact area with the gypsum board is small. As a result, the friction between the first transmission block and the second transmission block and the gypsum board is small, which ultimately leads to a poor clamping and fixing effect on the gypsum board.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.
