[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 and Figure 2 shown, the present utility model provides a gypsum board cutter structure, including a shaft rod 10, a cutting blade 20 is movably installed on the outer wall of the shaft rod 10, and a dust collection cover 30 is movably installed on the outer wall of the shaft rod 10. The dust collection cover 30 forms a semi-surrounding structure around the outer walls of the shaft rod 10 and the cutting blade 20. The dust collection cover 30 is provided with a collection port centered on the cutting blade 20. The lower surface of the dust collection cover 30 is movably abutted against the gypsum board surface to enclose the collection port to form a closed structure.

[0024] The present utility model adopts a form of movable connection to form a semi-surrounding dust collection structure, forming a duckbill-shaped collection structure on both sides of the cutter. The dust collection cover always remains in contact with the board surface following the cutting depth, so that the dust collection cover forms a closed structure in contact with the board surface while the cutter cuts the gypsum board, which can reduce the splashing of debris, is conducive to controlling and collecting the debris in the dust collection cover, facilitating the centralized cleaning of the debris, and reducing the problem that the debris remaining on the gypsum board surface causes small residues to affect the board surface quality.

[0025] While the cutting blade 20 rotates and cuts, the dust collection cover 30 forms a relatively sealed space with the gypsum board surface, which can control the debris in the dust collection cover 30. The dust collection cover 30 is connected to the negative pressure port of the dust collection fan, and the debris in the dust collection cover 30 is collected through the negative pressure kinetic energy. It can perform negative pressure collection treatment on the debris while cutting the gypsum board, reducing the adhesion of the debris on the gypsum board surface.

[0026] As Figure 2 shown, the dust collection cover 30 is composed of two groups of cover plates 31 fixed by bolts. A sealing strip is arranged at the connection position of the two groups of cover plates 31. The longitudinal section of the dust collection cover 30 is in a duckbill-shaped structure.

[0027] The dust collection cover 30 is formed by enclosing and fixing the two groups of cover plates 31 on both sides of the cutting blade 20, which is convenient for disassembly and installation. It is conducive to forming a relatively sealed space with the board surface on both sides of the incision while the cutting blade 20 cuts, so as to perform negative pressure collection operation.

[0028] As Figure 3 shown, a connecting rod 311 is fixedly connected to the inner wall of the cover plate 31, and a rod sleeve 11 matching the connecting rod 311 is fixedly connected to the outer wall of the shaft rod 10.

[0029] Through the clamping connection between the connecting rod 311 and the rod sleeve 11, it is convenient to fix the cover plate 31 on the outside of the shaft rod 10, so that the dust collection cover 30 rotates synchronously with the rotation of the shaft rod 10 and can cooperate with the cutting blade 20 for rotational cutting.

[0030] As Figure 2 shown, an adjustment groove 32 is formed on the lower surface of the cover plate 31, and an adjustment plate 33 is slidably connected to the inner wall of the cover plate 31 where the adjustment groove 32 is located. One side of the adjustment plate 33 is connected to the inner wall of the adjustment groove 32 through a spring 34.

[0031] By sliding and adjusting the adjustment plate 33 in the adjustment groove 32, a retractable adjustment structure is formed at the lower end of the cover plate 31, which can be adjusted according to the cutting depth of the cutting blade 20 on the board surface, so that the bottom end of the cover plate 31 can always fit the board surface for negative pressure collection operation. At the same time, through the elastic action of the spring 34, it can return to the initial state after a single cutting is completed for the next cutting operation.

[0032] As Figure 2 shown, a cushion block 35 is fixedly connected to the lower surface of the adjustment plate 33. The longitudinal section of the cushion block 35 is in a trapezoidal structure, and the lower surface of the cushion block 35 is in movable contact with the gypsum board panel.

[0033] A relatively sealed state is formed by the contact between the cushion block 35 and the gypsum board surface. And through the cushion block 35, the friction on the board surface can be reduced. The trapezoidal structure can better bring the debris in the cushion block 35 into the dust collection cover 30 and conduct centralized treatment through negative pressure.

[0034] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
