[0006] Furthermore, limit switches are provided at the front top of the bottom frame and at the middle near the top rear frame.

[0007] Furthermore, the dust cover has an inspection door and several ventilation windows on its side, with the ventilation windows spaced apart, and the inspection door and ventilation windows are equipped with screens.

[0008] Compared with the prior art, the beneficial effects of this utility model are that it sets up a dust cover around the paper machine to prevent the lint and dust falling off during the paper machine drying cylinder and winding from spreading everywhere. At the same time, a dust suction cover is installed in the winding area to remove dust from the winding area through negative pressure, thereby reducing the risk of dust being trapped in the raw paper, reducing the dust content in the workshop, and avoiding excessive dust that may harm the health of the workers. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is the side view of the top front frame. Detailed Implementation

[0010] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0011] Example 1 like Figure 1-2 As shown, the dust control device in the bamboo fiber-based base paper production paper machine workshop includes a dust cover 1. The dust cover 1 includes a rectangular support frame 2 erected around the outside of the paper machine and a dust cover 3 covering the support frame 2. The front end of the support frame 2 is equipped with a gantry 4 to facilitate the passage of large equipment. A curtain 5 is hung on the gantry 4 to close the dust cover 1 without affecting passage. The dust cover 1 is used to prevent the dust falling from the paper machine drying cylinder and during winding from spreading. At least two dust suction hoods 6 are provided at the front end of the dust cover 1 near the winding area of ​​the paper machine. The dust suction hoods 6 are connected to a dust suction pipe 7. The dust suction pipe 7 is connected to a negative pressure generator and to a dust treatment station outside the workshop through a dust exhaust pipe. The dust in the winding area is removed by negative pressure, reducing the risk of dust being carried in the base paper, reducing the dust content in the workshop, and avoiding excessive dust that may harm the health of the workers.

[0012] Because the rolled paper is heavy, it is generally hoisted from above to the storage area using lifting equipment. Therefore, the aforementioned support frame 2 includes a bottom frame 21, a top front frame 22, and a top rear frame 23. The top rear frame 23 is located above and behind the bottom frame 21 and is fixedly connected to the bottom frame 21. The top front frame 22 is located above and in front of the bottom frame 21.

The top end of the bottom frame 21 is provided with a slide rail 211 corresponding to the sliding wheels 221. The top front frame 22 slides along the slide rail 211 via the sliding wheels 221. A rack 222 is horizontally provided on the inner side of the lower part of the bottom frame 21. A geared motor 223 is fixedly installed at the top of the bottom frame 21 near the front end of the bottom rear frame 23. A gear 224 is fixedly connected to the output end of the geared motor 223. The gear 224 meshes with the rack 222. The geared motor 223 drives the gear 224 to rotate, which drives the rack 222 to move horizontally, thereby causing the top front frame 22 to slide back and forth. After the paper is curled, the geared motor is operated to move the top front frame 22 backward and into the top rear frame 23. The front part of the top of the dust cover is open to facilitate hoisting. After hoisting, the geared motor is operated to reverse, and the top front frame slides forward to cover the front of the dust cover.

[0013] Furthermore, limit switches 24 are provided at the top front of the bottom frame 21 and at the middle near the top rear frame 23 to control the travel of the top front frame 22.
