Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production equipment, and in particular to a cutting device used for producing paper-faced gypsum boards. Background Art

[0002] The existing ordinary gypsum board has been widely used in residences, office buildings, hotels and other places due to its characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method. In the production process of gypsum board, the gypsum board that has not yet dried after forming needs to be cut into fixed lengths online before it can be sent to the dryer for drying. Since the gypsum board that is cut is not yet dried, a large amount of gypsum residue will accumulate on the cutter during long-term use, which will not only affect the cutting effect of the cutter, but also accelerate the wear of the cutter and increase the production cost. The existing cleaning method usually relies on manual operation, which is not only inefficient but also has safety hazards.

[0003] Patent CN109382899A discloses a gypsum board cutting machine for a gypsum board production line, the structure of which includes a frame, an upper cutter device and a lower cutter device are arranged on the frame, the upper cutter device and the lower cutter device are arranged opposite to each other, and a brush device is respectively arranged above the upper cutter device and below the lower cutter device; the brush device includes a brush shaft, a brush roller is sleeved on the brush shaft, and the brush roller is fixedly sleeved on the brush shaft; a brush driving device is arranged above the frame, the brush driving device includes a brush motor, a driving sprocket and two driven sprockets, the two driven sprockets are respectively arranged at one end of the two brush shafts, and the output shaft of the brush motor is rotatably connected to the driving sprocket.

[0004] Although the above patent can clean the gypsum residue accumulated on the cutter when it is first used, the above patent introduces a brush device. The gypsum residue accumulated on the cutter is cleaned by the brush device. The gypsum residue will be transferred to the brush device. After long-term use, the cleaning effect will be significantly reduced. The brush device needs to be cleaned to ensure the cleaning effect, and the production efficiency is still low.
