[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Combination Figures 1-3 A paper surface pretreatment device includes a support 1, on which a transmission mechanism 2 is provided; the transmission mechanism 2 includes four mounting plates 201, which are respectively fixedly installed on both sides of the support 1; two brush shafts 202 are rotatably mounted in parallel inside the support 1; two belts 203 are sleeved on the two brush shafts 202; a motor 204 is fixedly installed on one side of the support 1; a slide block 205 is slidably mounted on the mounting plate 201; a roller 206 is rotatably mounted between the two slide blocks 205; and a support spring 207 is fixedly installed between the slide block 205 and the mounting plate 201.

[0019] The brush shaft 202 is located diagonally above the roller 206, and one brush shaft 202 is fixedly installed on the output end of the motor 204. When the paper is passed through the two rollers 206, it ensures that the different sides of the paper are facing upwards and that impurities on it are brushed off by the brush shaft 202. At the same time, the paper tension is made uniform by the continuous beating of the brush shaft 202. The mounting plate 201 has a strip groove, and the slide 205 is snapped onto the strip groove. The strip groove is used to limit the movement of the slide 205 and ensure that the roller 206 moves horizontally between the two mounting plates 201. The upper and lower rollers 206 are respectively staggered and installed on the upper and lower mounting plates 201. The upper and lower support springs 207 are respectively located on different sides of the upper and lower rollers 206, so that the paper is pulled into a Z-shape. Under the action of the support springs 207, it plays a buffer protection role and prevents the paper from being torn due to tightness.

[0020] Example 2 See Figure 4 A dust collection mechanism 3 is provided on two mounting plates 201. The dust collection mechanism 3 includes a first bracket 301 and a second bracket 302. The first bracket 301 is fixedly installed between the two upper mounting plates 201, and the second bracket 302 is fixedly installed between the two lower mounting plates 201. A fan seat 303 is fixedly installed on both the first bracket 301 and the second bracket 302. A dispersion net 304 is fixedly installed on the fan seat 303, and a hose 305 is fixedly installed on the fan seat 303. A wind pump 306 is fixedly installed on one side of the support 1.

[0021] The opening of the air seat 303 faces the roller 206, ensuring that the air seat 303 can absorb impurities on the surface of the paper when it is facing down. The air seat 303 is fixedly connected to the air pump 306 through the hose 305. The air pump 306 provides suction to the air seat 303 through the hose 305. The dispersing net 304 has the effect of dispersing the air force, ensuring that the impurities on the paper are absorbed evenly. The first bracket 301 and the second bracket 302 are respectively fixedly installed on the lower side of the upper and lower mounting plates 201 in an alternating manner. Their function is to fix the air seat 303 under different sides of the paper. The length of the air seat 303 is the same as the length of the roller 206.

[0022] In actual operation, the roller 206 is fixed on the mounting plate 201 by the slide 205, and the slide 205 is supported by the support spring 207. Benefiting from the position of the slide 205, the roller 206 and the support spring 207, when the paper is passed on the roller 206, the paper will be connected in a Z-shape, and the brush shaft 202 will be driven by the motor 204 to hit different sides of the paper and the upward surface, so that the impurities on different sides of the paper are brushed up, and at the same time, the tension of the paper is released, ensuring that the tension of the paper is evenly distributed. When different sides of the paper are patted by the brush shaft 202, the paper surface will flip downwards due to the action of the roller 206. At this time, the control pump 306 generates suction on the air seat 303 and disperses the suction by the dispersing net 304, thereby deeply sucking impurities on the paper surface into the air seat 303 and then discharging them, achieving the effect of removing impurities from the paper. Since the air seat 303 is located on the lower side of the roller 206, it can prevent impurities from being rolled onto the paper.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
