Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for book printing. Background Art

[0002] In the process of book printing, a large amount of paper scraps, toner and other particles are usually generated. These particles will not only affect the quality of the printed products, but also cause damage to the respiratory system of the workers. Therefore, dust removal devices are usually used in book printing to effectively reduce the emission of these particles and provide workers with a more comfortable working environment. However, the existing dust removal devices have a low dust removal effect and cannot ensure that the paper surface is smooth and tidy before printing.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN220311077U proposes a high-efficiency dust removal device for book printing equipment. The device uses a brush to lift the dust adsorbed on the surface of the paper, and the lifted dust is quickly sucked away by an electrostatic dust collector, thereby removing the dust on the surface of the paper. During the printing process, the dust box cooperates with the negative pressure motor to remove the dust inside the printing machine. The surface of the paper is smooth and tidy before printing, ensuring the printing effect.

[0004] However, although the above-mentioned high-efficiency dust removal device of the book printing equipment can lift the dust on the surface of the paper through the brush and have it adsorbed by the electrostatic dust collector, thereby ensuring that the surface of the paper is smooth and tidy before printing, the brush of the high-efficiency dust removal device of the book printing equipment will accumulate most of the dust inside after long-term use, making the brush hard, thereby causing damage to the paper when it comes into contact with the paper. Therefore, the utility model provides a dust removal device based on book printing to meet the needs. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology, and to propose a dust removal device based on book printing.

[0006] The technical problem to be solved by the utility model is to provide a dust removal device for book printing to solve the problem that after long-term use, most of the dust will gather inside the brush of the existing dust removal device, making the brush hard, thereby causing damage to the paper when it contacts with the paper.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A dust removal device for book printing, comprising:

[0009] A base, a printing device with an inlet and an outlet is provided on the top of the base, a dust collecting device is provided on the top of the printing device, two rollers are connected at the inlet for relative rotation through a support plate, and brushes are provided on the rollers;

[0010] The first fixed cylinder is arranged at the inlet, and a plurality of scrapers that contact the brush are arranged at intervals opposite to the roller. The interior of the first fixed cylinder is a hollow structure, and a dust suction port connected to the interior of the roller is penetrated through the first fixed cylinder, and the interior of the first fixed cylinder is connected to the dust suction device through a pipeline.

[0011] Preferably, a gap is formed between adjacent scrapers for the brush to pass through, and the gap is smaller than the diameter of the brush.

[0012] Preferably, the top of the scraper is provided with a plurality of scraping grooves arranged along the length direction thereof.

[0013] Preferably, a cavity is provided inside the roller, a through hole communicating with the cavity is penetrated through the roller, and the cavity is connected with the dust collecting device through a pipeline.

[0014] Preferably, the roller and the pipe are rotatably connected via a rotary joint.

[0015] Preferably, the through holes are arranged at intervals between adjacent brushes.

[0016] Preferably, the dust suction port is arranged on the first fixed cylinder in an upper and lower relative manner along the scraper.

[0017] Preferably, it also includes a second fixed cylinder, which is fixedly connected to the bottom of the first fixed cylinder. The interior of the second fixed cylinder is a hollow structure. The end surface of the second fixed cylinder facing the roller is penetrated by an exhaust hole connected to the interior of the roller. The printing device body is fixedly connected to an exhaust fan connected to the interior of the second fixed cylinder.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] In the above scheme, by providing a scraper, the cooperation of multiple scrapers can facilitate the scraping of dust on the brush and adsorption by the dust collection device, thereby preventing the brush from becoming hard due to long-term use and avoiding damage to paper.

[0020] In the above scheme, by setting the scraping groove, the through hole and the cavity, the setting of the scraping groove is convenient for collecting dust and discharging it to the dust suction port; when the dust suction device is started, the dust on the paper is discharged along the through hole to the inside of the cavity, and finally discharged to the inside of the dust suction device, thereby further improving the cleaning effect of the dust on the paper.

[0033] like Figures 1 to 8As shown, an embodiment of the utility model provides a dust removal device for book printing, including a base 1, a printing device 2 with an inlet 5 and an outlet 6 is provided on the top of the base 1, a dust collection device 3 is provided on the top of the printing device 2, two rollers 8 are connected at the inlet 5 for relative rotation through a support plate 4, a brush 11 is provided on the roller 8, a first fixed cylinder 9 is arranged at the inlet 5, a plurality of scrapers 15 that contact with the brush 11 are arranged opposite to the first fixed cylinder 9, the first fixed cylinder 9 has a hollow structure inside, a dust collection port 14 is penetrated by the first fixed cylinder 9 opposite to the roller 8 and connected to the inside of the first fixed cylinder 9, and the inside of the first fixed cylinder 9 is connected to the dust collection device 3 through a pipe 10.

[0034] Specifically, when the paper enters the printing device 2 along the inlet 5, the paper must first pass between the two rollers 8. At this time, the brush 11 contacts the paper and guides the paper to the inside of the printing device 2. The roller 8 drives the brush 11 to rotate when it rotates, so that the brush 11 contacts the scraper 15, and the dust gathered on the brush 11 is scraped off by the scraper 15. At the same time, the dust suction device 3 is started, so that the dust suction device 3 generates suction, so that the dust at the scraper 15 is sucked into the first fixed cylinder 9 through the dust suction port 14, thereby avoiding the phenomenon that the brush 11 becomes hard after long-term use and avoids damage to the paper. At the same time, it can also prevent the dust from entering the printing device when the brush 11 rotates, which solves the problem that the brush 11 of the existing dust removal device will gather most of the dust inside after long-term use, causing the brush 11 to harden, thereby causing damage to the paper when it contacts the paper.

[0035] It should be noted that the two rollers 8 rotate relative to each other and can be driven to rotate by external equipment or external force. This is the prior art. The brush 11 is usually made of a soft and elastic material, such as wool. At the same time, the printing equipment and the dust collection equipment 3 can refer to the Chinese patent with announcement number CN220311077U, which proposes a case of a high-efficiency dust removal device for book printing equipment, which will not be described in detail here.

[0036] like Figure 4 and Figure 5 As shown, in the present embodiment, a gap is formed between adjacent scrapers 15 for the brush 11 to pass through, and the gap is smaller than the diameter of the brush 11. Specifically, the brush 11 passes through the gap between adjacent scrapers 15 when rotating. The scrapers 15 on both sides can be used to scrape the dust gathered in the brush 11 to the top of the scraper 15, so as to facilitate better suction into the first fixed cylinder 9 along the dust suction port 14.

[0037] like Figure 8 As shown, in this embodiment, a plurality of scraping grooves 18 are provided on the top of the scraper 15 and arranged along the length direction thereof. Specifically, the scraping grooves 18 are provided to facilitate the collection of dust and the discharge of dust to the dust suction port 14 .

[0038] like Figures 2 to 7 As shown, in the present embodiment, a cavity 17 is provided inside the roller 8, a through hole 12 connected to the cavity 17 is penetrated through the roller 8, the cavity 17 is connected to the dust collecting device 3 through a pipe 10, and the roller 8 and the pipe 10 are rotatably connected through a rotary joint. Specifically, when the dust collecting device 3 is started, the dust on the paper is discharged along the through hole 12 to the inside of the cavity 17, and finally discharged to the inside of the dust collecting device 3, thereby further improving the cleaning effect of the dust on the paper.

[0039] like Figure 4 and Figure 5 As shown, in this embodiment, the through holes 12 are arranged between adjacent brushes 11 at intervals, and the dust suction ports 14 are arranged on the first fixed cylinder 9 along the scraper 15 in an upper and lower relative manner.

[0040] like Figure 2 and Figure 4 As shown, in the present embodiment, a second fixed cylinder 13 is further included, which is fixedly connected to the bottom of the first fixed cylinder 9. The interior of the second fixed cylinder 13 is a hollow structure. The end surface of the second fixed cylinder 13 facing the roller 8 is penetrated by an exhaust hole 16 connected to the interior thereof. An exhaust fan 7 connected to the interior of the second fixed cylinder 13 is fixedly connected to the printing device 2 body. Specifically, by starting the exhaust fan 7, the exhaust fan 7 transports airflow toward the interior of the second fixed cylinder 13, and discharges the airflow along the exhaust hole 16 to the roller 8 of the brush 11. The advantage of this is that the drying of the brush 11 can be accelerated and dust can be prevented from being discharged into the interior of the printing device 2 along the inlet 5.

[0041] Working principle:

[0042] First, the printing device 2, the dust collecting device 3 and the exhaust fan 7 are connected to an external power supply, and then the paper passes between the two rollers 8. At this time, the brush 11 contacts the paper and guides the paper to be discharged into the printing device 2. When the roller 8 rotates, it drives the brush 11 to rotate, so that the brush 11 contacts the scraper 15, and the dust gathered on the brush 11 is scraped off by the scraper 15. At the same time, the dust collecting device 3 and the exhaust fan 7 are started, so that the dust collecting device 3 generates suction, so that the dust at the scraper 15 is sucked into the first fixed cylinder 9 through the dust suction port 14, and the dust on the paper is discharged to the cavity along the through hole 12. The exhaust fan 7 is started to deliver wind toward the inside of the second fixed cylinder 13, and the wind is discharged to the roller 8 of the brush 11 along the exhaust hole 16, thereby preventing the brush 11 from becoming hard after long-term use and damaging the paper. At the same time, it can also prevent the dust from entering the printing equipment when the brush 11 rotates, thereby solving the problem that most of the dust will gather inside the brush 11 of the existing dust removal device after long-term use, causing the brush 11 to become hard, thereby causing damage to the paper when it comes into contact with the paper.
