Technical Field

[0001] The utility model relates to the field of paper roll manufacturing, in particular to a paper roll material surface cleaning device. Background Art

[0002] Color frame paper is a customized printing product launched for tobacco companies in the packaging and printing industry in recent years. It is favored by major tobacco companies for its exquisite craftsmanship, beautiful appearance and super anti-counterfeiting performance. In the production process of color frame paper, before the frame paper roll enters the web printing machine for printing, due to the production process of the roll, the front and back of the roll will be attached to different degrees of paper dust and impurities in the air during the production process. These impurities will seriously affect the product quality and production efficiency of the printing company.

[0003] In the prior art, two methods are generally used to remove dust from the surface of paper rolls: manual dust removal and paper sticking roller dust removal.

DETAILED DESCRIPTION

[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] Please refer to Figure 1 and Figure 2 The paper roll surface cleaning device of the utility model comprises a box body 1, an ultrasonic sound generator 2, a brush roller 3, a vibration mechanism 4 for driving the paper 8 to vibrate, and a vacuum cleaner 5 connected to the inside of the box body 1. The box body 1 has an inlet 11 and an outlet 12 for the paper 8 to enter and exit. The ultrasonic sound generator 2, the brush roller 3, and the vibration mechanism 4 are arranged in the box body 1 at the positions of the inlet 11 and the outlet 12, and the brush roller 3 and the vibration mechanism 4 are arranged along the width direction of the box body 1 and spaced from each other in the length direction of the box body 1, so that the paper 8 can enter the box body 1 from the inlet 11 and pass through it in sequence.

[0027] The upper part of the box body 1 is provided with a box cover 13, and the box cover 13 is detachably connected to the box body 1 by bolts 14. The inlet 11 is opened at one end of the length direction of the box body 1, and the inlet 11 is provided with two first baffles 111 symmetrically arranged in the upper and lower parts, and the two first baffles 111 are both inclined, and the first baffle 111 located at the upper part gradually inclines from the inlet 11 to the inside of the box body 1 from top to bottom, and the first baffle 111 located at the lower part gradually inclines from the inlet 11 to the inside of the box body 1 from bottom to top. The outlet 12 is opened at the other end of the length direction of the box body 1 and corresponds to the position of the inlet 11, and the outlet 12 is provided with two second baffles 121 symmetrically arranged in the upper and lower parts, and the two second baffles 121 are both inclined, and the second baffle 121 located at the upper part gradually inclines from the inlet 11 to the outside of the box body 1 from top to bottom, and the second baffle 121 located at the lower part gradually inclines from the inlet 11 to the outside of the box body 1 from bottom to top. The vacuum cleaner 5 is arranged on the side wall of the box body 1 so as to suck out the impurities in the box body 1. The arrangement of the first baffle 111 and the second baffle 121 can form a relatively stable negative pressure environment in the box body 1, which is convenient for the vacuum cleaner to adsorb; at the same time, the first baffle 111 and the second baffle 121 can also slightly scrape the surface of the paper 8 to remove the impurities thereon. It is worth noting that the first baffle 111 and the second baffle 121 are both made of deformable rubber material to avoid damaging the paper 8 due to the material being too hard to deform. There are two groups of ultrasonic sound generators 2, and the two groups of ultrasonic sound generators 2 are respectively installed at the positions corresponding to the inlet 11 and the outlet 12 in the box body 1. The number of ultrasonic sound generators 2 in each group of ultrasonic sound generators 2 is two, and the two ultrasonic sound generators 2 located at the inlet 11 are respectively located above and below the inlet 11, and the sounding directions of the two ultrasonic sound generators 2 are opposite. The two ultrasonic sound generators 2 located at the outlet 12 are respectively located above and below the outlet 12 and the sound emission directions of the two ultrasonic sound generators 2 are opposite.

[0028] Please refer to Figure 3 The number of the brush rollers 3 is two and the two brush rollers 3 are distributed up and down to be respectively located on the upper and lower sides of the paper 8. Each brush roller 3 is horizontally arranged along the width direction of the box body 1, and both ends of the brush roller 3 are rotatably connected to the inner wall of the box body 1 through a connecting shaft, and the outer diameter of the connecting shaft is smaller than the outer diameter of the brush roller 3. The brush roller 3 can rotate around its own axis. The two brush rollers 3 are driven by a set of first driving mechanisms 6. Please refer to Figure 3 and Figure 4, the first driving mechanism 6 includes a driving gear 61, a driven gear 62 and a first rotating motor 63. A groove 15 is provided at the position of the side wall of the box body 1 corresponding to the brush roller 3. The driving gear 61 is rotatably arranged in the groove 15 and is coaxially fixed with one of the brush rollers 3. The driven gear 62 is rotatably arranged in the groove 15 and meshes with the driving gear 61. The driven gear 62 is coaxially fixed with the other brush roller 3. The first rotating motor 63 is arranged on the side wall of the box body 1 and the output shaft of the first rotating motor 63 extends into the groove 15 and is transmission-connected with the driving gear 61. Therefore, the two brush rollers 3 can rotate in opposite directions under the drive of the first driving mechanism 6. In order to make the brush roller 3 have a better cleaning effect on the paper 8, we adjust the rotation direction of the first rotating motor 63 so that the rotation direction of the two brush rollers 3 is opposite to the moving direction of the paper 8. Taking the attached figure as an example, if the paper 8 moves from left to right, the brush roller 3 above the paper 8 rotates clockwise, and the brush roller 3 below the paper 8 rotates counterclockwise (based on the direction in the attached figure). A cleaning member 64 for cleaning the brush roller 3 is also provided at a position corresponding to the brush roller 3 in the box body 1.

[0029] Please refer to Figure 2 , Figure 3 and Figure 5 The cleaning member 64 includes two circular rings 641 corresponding to the two brush rollers 3, and the two circular rings 641 are coaxially arranged with the two brush rollers 3. The inner diameter of the circular ring 641 is smaller than the outer diameter of the brush roller 3 so as to scrape the bristles on the brush roller 3. Meanwhile, the inner diameter of the circular ring 641 is larger than the outer diameter of the connecting shaft. When the circular ring 641 is not in operation, it will be located outside the connecting shaft, so as not to affect the normal use of the brush roller 3. The two circular rings 641 are connected to each other on the sides close to each other, and the two circular rings 641 are driven by a set of the second driving mechanism 7 so as to reciprocate along the length direction of the brush roller 3.

[0030] The second driving mechanism 7 includes a screw rod 71, a slide bar 72 and a second rotary motor 73. The screw rod 71 is arranged in the box body 1 along a direction parallel to the brush roller 3, and both ends of the screw rod 71 are rotatably connected to the inner side wall of the box body 1. The second rotary motor 73 is arranged at a position on the outer side wall of the box body 1 corresponding to the screw rod 71, and the output shaft of the second rotary motor 73 extends into the box body 1 and is transmission-connected to the screw rod 71. The slide bar 72 is arranged parallel to the screw rod 71 and is located below the screw rod 71, and both ends of the slide bar 72 are fixedly connected to the inner side wall of the box body 1. The two rings 641 are close to the screw rod 71 and one side of the slide bar 72 protrudes outward with a connecting block 642. The connecting block 642 on the upper ring 641 is screwed to the screw rod 71, and the connecting block 642 on the lower ring 641 is slidably connected to the slide bar 72.

[0031] Please refer to Figure 3 and Figure 6 The vibration mechanism 4 includes a round roller 41 and a vibration motor 42. The number of the round rollers 41 is two and the two round rollers 41 are distributed up and down to be respectively located on the upper and lower sides of the paper 8. The two round rollers 41 are arranged along the width direction of the box body 1 and are located on the lateral side of the brush roller 3, specifically, on the side of the brush roller 3 close to the outlet 12. There is an installation space in the middle of each round roller 41, and a vibration motor 42 is installed in each installation space. Connecting rods 43 are arranged at both ends of the length direction of the round roller 41, and the connecting rods 43 are arranged along the length direction of the round roller 41. Fixed frames 16 are arranged on both lateral side walls of the box body 1, and the openings of the two fixed frames 16 are opposite. The two connecting rods 43 extend into the two fixed frames 16 respectively, and elastic members 44 are fixed between the upper and lower ends of the connecting rods 43 and the inner wall of the fixed frame 16. In the embodiment shown, the elastic member 44 is a coil spring. The round roller 41 can be moved and reset in a vertical direction relative to the box body 1 under the drive of the vibration motor 42 .

[0032] One embodiment of the paper roll surface cleaning device of the utility model works as follows: the paper 8 to be processed enters the box body 1 through the inlet 11, and the ultrasonic sounder 2 at the inlet 11 generates high-frequency sound waves, and the impurities on the paper 8 are separated from the paper 8 through the vibration of the sound waves. The paper 8 then enters between the two brush rollers 3, and the two brush rollers 3 rotate under the drive of the first rotating motor 63, and sweep the impurities on the surface of the paper 8 off. The paper 8 then enters the vibration mechanism 4, and the two round rollers 41 contact the upper and lower surfaces of the paper 8 respectively. The two round rollers 41 vibrate the paper 8 under the drive of the vibration motor 42, so that the impurities on the surface of the paper 8 are more easily separated from the paper 8, and the ultrasonic sounder 2 at the outlet 12 further separates the impurities from the paper 8 through the vibration of the sound waves, so that the surface of the paper 8 is cleaner. The vacuum cleaner 5 sucks the impurities in the box body 1 out of the box body 1 to prevent the impurities from accumulating or flying in the box body 1 and returning to the surface of the paper 8 again.

[0033] As the use time increases, some dust or impurities may accumulate in the gaps between the bristles of the brush roller 3 and cannot fall off naturally. At this time, the cleaning member 64 is used to scrape the brush roller 3 to remove the impurities thereon. The steps are as follows: start the second rotary motor 73, the second rotary motor 73 drives the screw 71 to rotate, the slide bar 72 has a limiting effect on the cleaning member 64 so that it cannot rotate, so the cleaning member 64 moves along the length direction of the screw 71 as the screw 71 rotates, and when the rotation direction of the second rotary motor 73 changes, the moving direction of the cleaning member 64 also changes.
