[0024] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] Reference Figures 1-4 The present invention provides a vacuum control device for a papermaking machine, comprising: a base 1, a vacuum pump body 2 being provided above the base 1, an output end of the vacuum pump body 2 being fixedly connected to a vacuum box body 3 via a pipe, a filter unit 4 being provided inside the vacuum box body 3, and a suction pipe 5 being provided on a side of the vacuum box body 3 away from the vacuum pump body 2;

[0026] The filter unit 4 includes three mounting brackets 401 fixedly connected to the inner wall of the vacuum box body 3. The inner walls of the three mounting brackets 401 are each provided with a limiting groove 402. The inner walls of the three limiting grooves 402 are each slidably connected to a filter frame 403. The inner walls of the three filter frames 403 are respectively provided with a first filter screen 404, a second filter screen 405, and a third filter screen 406. A cleaning unit 6 is provided on the inner wall of the vacuum box body 3 and on one side of the three mounting brackets 401. The filter unit 4 can filter debris in the air.

[0027] The cleaning unit 6 includes grooves 601 disposed on the inner wall of the vacuum box body 3 and located on one side of the three mounting brackets 401. A screw 602 is rotatably connected to the inner wall of the groove 601. A sliding seat 603 is sleeved on the outer wall of the screw 602. A connecting bracket 604 is fixedly connected to the opposite side of the sliding seat 603. A cleaning brush 605 is fixedly connected to one side of the connecting bracket 604. The cleaning unit 6 can remove debris adsorbed on the first filter 404, the second filter 405, and the third filter 406.

[0028] The cleaning brush 605 is located on one side of the first filter 404 , the second filter 405 and the third filter 406 , respectively, and the cleaning brush 605 is adapted to one side of the first filter 404 , the second filter 405 and the third filter 406 .

[0029] The apertures of the first filter 404, the second filter 405, and the third filter 406 are divided into small, medium, and large apertures, and the first filter 404, the second filter 405, and the third filter 406 are sequentially arranged and distributed inside the vacuum box body 3. The first filter, the second filter 405, and the third filter 406 perform multi-stage filtration of impurities in the air.

[0030] The bottom wall of the vacuum box body 3 is provided with three motors 301, and the output ends of the three motors 301 are respectively fixedly connected to the three screw rods 602. The three motors 301 can drive the three screw rods 602 to rotate.

[0031] A cover 302 is provided above the vacuum box body 3, with fixing bolts threaded onto the cover 302. Opening the cover 302 allows for cleaning debris from the vacuum box body 3, and allows the filter frame 403 to be removed from the mounting bracket 401 to clean or replace the first, second, and third filters 404, 405, and 406.

[0032] Two sets of support frames 101 are fixedly connected to the top of the base 1, and the upper ends of the two sets of support frames 101 are respectively fixedly connected to the lower ends of the vacuum pump body 2 and the vacuum box body 3. The two sets of support frames 101 improve the stability of the vacuum pump body 2 and the vacuum box body 3.

[0033] Working principle: When in use, connect the suction pipe 5 on one side of the vacuum box body 3 to the papermaking machine, and start the vacuum pump body 2, and extract air from the vacuum box body 3 through the pipe. During the air extraction process, it will contain debris and other impurities. These impurities enter the vacuum box body 3 and are filtered through the first filter screen 404, the second filter screen 405 and the third filter screen 406 to avoid damage to the vacuum pump body 2. During long-term filtration, the first filter screen 404, the second filter screen 405 and the third filter screen 406 will be blocked, affecting the filtration efficiency. The motor 301 can be started to drive the corresponding screw rod 602 to rotate, so that the sliding seat 603 on the screw rod 602 moves along the groove 601, and drives the cleaning brush 605 on one side of the connecting frame 604 to clean the surface of the first filter screen 404, the second filter screen 405 and the third filter screen 406.
