It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0019] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0020] As Figures 1 to 3 shown, in the embodiment of the present utility model: A trimming device for gypsum board processing includes a support plate 1. On both sides of the bottom end of the support plate 1, support columns 101 are fixed. Below the support plate 1, a first stepping motor 2 is provided. The output shaft of the first stepping motor 2 is fixedly installed with a trimming milling cutter 201. At the bottom of the first stepping motor 2, a moving seat 202 is fixed. Between the two groups of support columns 101, an adjusting screw rod 203 is rotatably arranged. On the outer surface of the support column 101, a servo motor 204 is installed. The output shaft of the servo motor 204 is fixedly connected to the right end of the adjusting screw rod 203. On the top of the support plate 1, a protective shell 4 is installed. At the top end inside the protective shell 4, two hydraulic rods 401 are fixed. Between the bottom ends of the two hydraulic rods 401, a fixing plate 402 is installed. At the top of the protective shell 4, a dust collector 5 is installed. At the top end inside the protective shell 4, a dust suction hood 501 is installed. A dust suction pipe 502 is connected between the dust suction hood 501 and the dust collector 5.

[0021] A strip-shaped movable groove is formed on the surface of the support plate 1, and the trimming milling cutter 201 is arranged in the strip-shaped movable groove.

[0022] A threaded hole is formed on the surface of the moving seat 202, and the surface of the adjusting screw rod 203 is in threaded connection with the threaded hole inside the moving seat 202. After driving the adjusting screw rod 203 to rotate in a spiral manner, the adjusting screw rod 203 can drive the moving seat 202 to move parallelly.

[0023] A limiting guide rod 3 is fixed between the two groups of support columns 101. The limiting guide rod 3 is arranged below the adjusting screw rod 203, and a round hole is formed on the surface of the moving seat 202. The limiting guide rod 3 passes through the round hole on the surface of the moving seat 202. By sliding the moving seat 202 on the surface of the limiting guide rod 3, the moving seat 202 is restricted from rotating when being driven to move parallelly.

[0024] A positioning baffle 7 is installed on the top of the support plate 1. One side of the gypsum board abuts against the surface of the positioning baffle 7. Through the positioning baffle 7, it is convenient to place the gypsum board neatly, so that the edge of the gypsum board can be parallel to the strip-shaped movable groove on the surface of the support plate 1.

[0025] On both sides of the protective shell 4, a second stepping motor 6 is installed. At one end of the output shaft of the second stepping motor 6 inside the protective shell 4, a fan 601 is fixed. On both sides inside the support plate 1, protective covers 602 are installed. The fan 601 is arranged inside the protective covers 602. After the fan 601 rotates, the lime powder generated by trimming can be blown towards the dust suction hood 501, facilitating the dust suction hood 501 to suck away the lime powder.

[0026] In summary, the working principle of the present utility model is as follows: Place the gypsum board above the support plate 1 and align the edge of the gypsum board parallel to the strip-shaped movable groove on the surface of the support plate 1. Then, the hydraulic rod 401 is used to push the fixed plate 402 downward to move, so that the fixed plate 402 fixes the gypsum board. Then, the servo motor 204 is powered on to drive the adjusting screw 203 to rotate in a spiral manner, so that the adjusting screw 203 can drive the moving seat 202 to move parallel. Then, when the moving seat 202 drives the first stepping motor 2 to move, the first stepping motor 2 is powered on to drive the trimming cutter 201 to rotate at a high speed. The first stepping motor 2 drives the trimming cutter 201 to move and polish the edge of the gypsum board. Then, lime powder will be generated during the polishing process. Therefore, due to the suction force generated by the operation of the dust collector 5, the dust suction hood 501 sucks away the lime powder, reducing the lime powder and preventing the lime powder from causing air pollution in the surrounding area and affecting the healthy breathing of the device operators.

[0027] The above is only a preferred embodiment of the present utility model, and it does not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
