Description

Technical Field

[0001] This utility model belongs to the field of printing press dust removal technology, and in particular relates to a paper dust removal device for printing presses. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, printing, and paper feeding. Its working principle is as follows: first, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied to the areas of the printing plate containing the text and images, either manually or by the printing press itself, and then directly or indirectly transferred to paper or other printing substrates.

[0003] An existing patent (publication number: CN213001572U) discloses the technical field of dust removal equipment, specifically relating to a dust removal device for a paper printing press, including a housing mechanism, a dust collection mechanism, and a paper pressing mechanism. The dust collection mechanism is disposed within the housing mechanism, and the paper pressing mechanism is disposed within the housing mechanism and mounted on the dust collection mechanism. There are two dust collection mechanisms and two paper pressing mechanisms, which are also symmetrically arranged. The dust collection mechanism includes a first air pipe, a second air pipe, and an air intake. The second air pipe is horizontally disposed at the bottom end of the first air pipe, and the air intake is disposed on the second air pipe.

[0004] Currently, printing presses typically require paper feeding assistance during printing. However, during the paper feeding process, dust from the external environment can easily adhere to the surface of the printing paper or substrate, potentially causing static electricity and affecting printing quality. Furthermore, traditional paper dust removal devices are not very effective and can easily damage the paper. Therefore, a paper dust removal device for printing presses is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a paper dust removal device for printing presses, which has the advantages of keeping printing paper clean during printing and not causing damage to the paper or substrate during the cleaning process. It solves the problems mentioned in the above-mentioned prior art, such as dust easily adhering to the surface of printing paper or substrate, which may cause static electricity and affect printing quality, and the fact that traditional paper dust removal devices have unsatisfactory dust removal effects and are prone to damaging the paper.

[0006] To achieve the above objectives, this application provides the following technical solution: a paper dust removal device for a printing press, comprising a fixed frame, a support device fixedly installed on the top of the fixed frame, a sliding device fixedly connected to the inner wall of the support device, a dust suction device provided on the top of the sliding device, a dust brushing mechanism provided on the inner wall of the support device, an inner through groove formed in the inner wall of the support device, an input end of the dust suction device extending to the bottom of the inner through groove, an electrostatic dust removal mechanism fixedly installed on the top of the fixed frame, a guiding component fixedly connected to one end of the fixed frame, and an installation hole formed on the top of the fixed frame.

[0007] With the above solution, by placing the dust brushing mechanism inside the support device, after the paper feeding mechanism delivers the printing paper to the printing equipment, the dust brushing mechanism rotates above the printing paper and contacts its surface to clean and absorb the dust. In conjunction with the sliding device, the dust suction device moves and sucks up the dust brushing mechanism from above. Thus, the dust attached to the surface of the printing paper can be removed before it enters the printing area. Furthermore, an electrostatic dust removal mechanism is set on one side of the support device so that after the printing paper passes under it, the surface of the printing paper can be electrostatically dusted, ensuring that the printing paper remains clean during printing and that the cleaning process does not damage the paper or the substrate.

[0008] Furthermore, the support device includes a support frame, a positioning seat is fixedly connected to the top of the support frame, the sliding device is located on the inner wall of the positioning seat, and the inner wall of the positioning seat is provided with a limit slide.

[0009] The above solution provides a moving support and limiting function for the dust collection device by fixing the support frame to the paper feed channel of the printing equipment and cooperating with the limiting slide inside the positioning seat.

[0010] Furthermore, the sliding device includes an electric slide rail, a drive motor is provided at the top of the electric slide rail, and the bottom of the vacuuming device is slidably connected to the inside of the electric slide rail.

[0011] The above scheme involves starting the drive motor to drive the electric slide rail to move horizontally above it, causing the input end of the vacuum cleaner to move along the inside of the inner groove and move to vacuum near the dust brushing mechanism, so that the dust attached to the dust brushing mechanism is sucked out.

[0012] Furthermore, the vacuuming device includes a vacuum fan, a vacuum pipe is threadedly connected to the bottom of the vacuum fan, a slide is fixedly installed at the bottom of the vacuum fan, the slide is slidably connected to the inside of the limiting slide, a fixed box is fixedly connected to the back of the vacuum fan, and a guide block is fixedly connected to the bottom of the fixed box.

[0013] The above solution connects the guide slider to the internal components of the electric slide rail. When the electric slide rail is started, it drives the guide slider to slide inside, which in turn moves the slide block against the inner wall of the limiting slide. This provides displacement driving force for the vacuum blower, allowing it to move back and forth above the dust brush mechanism in conjunction with the vacuum pipe. This sucks up the dust adhering to the dust brush mechanism, reducing the adhesion and scattering of dust.

[0014] Furthermore, the electrostatic dust removal mechanism includes a dust removal frame, and an electrostatic dust collector is provided on the inner wall of the dust removal frame, with the electrostatic dust collector located on one side of the support frame.

[0015] With the above solution, after the printing paper has undergone preliminary dust removal, when it passes under the dust removal rack, the electrostatic precipitator is activated, so that the printing paper undergoes electrostatic dust removal again before it reaches the printing area, thereby improving the printing quality of the printing paper.

[0016] Furthermore, the dust brushing mechanism includes a brush roller, one end of which is fixedly equipped with a dust brushing motor, and the brush roller is located inside the support frame.

[0017] The above solution involves starting the dust brush motor to drive the brush roller to rotate, causing the soft bristles on the brush roller to come into contact with the surface of the printing paper, generating slight friction to attract dust. As the brush roller continues to rotate and change surfaces to ensure that the dust is evenly attached, the dust can be quickly sucked out with the help of the suction pipe to achieve a highly efficient cleaning effect.

[0018] Furthermore, the guiding assembly includes a connecting plate, and a guiding roller is rotatably connected to the inner wall of the connecting plate.

[0019] The above scheme uses two sets of connecting plates to support the guide roller at the initial end of the fixed frame, which can provide a paper pressing and guiding effect at the paper feeding end of the printing equipment, so that the printing paper can be laid flat on the printing equipment for transmission.

[0020] Furthermore, sealing plates are fixedly connected to both the front and back of the support frame.

[0021] The above method uses bolts to fix the sealing plate to the support frame. If necessary, the sealing plate can be disassembled to facilitate cleaning and maintenance of the components inside the support frame.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This paper dust removal device for printing presses places a dust brushing mechanism inside a support device. After the paper feeding mechanism delivers the printing paper to the printing equipment, the dust brushing mechanism rotates above the printing paper and contacts its surface to clean and absorb dust. In conjunction with a sliding device, a suction device moves above the dust brushing mechanism to suck up the dust. This removes dust adhering to the surface of the printing paper before it enters the printing area. Furthermore, an electrostatic dust removal mechanism is provided on one side of the support device so that after the printing paper passes underneath, its surface can be electrostatically dusted. This ensures that the printing paper remains clean during printing, and the cleaning process does not damage the paper or the printing substrate. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1 , Figure 2 and Figure 3This embodiment of a paper dust removal device for a printing press includes a fixed frame 1, a support device 2 fixedly mounted on the top of the fixed frame 1, a sliding device 3 fixedly connected to the inner wall of the support device 2, a dust suction device 4 disposed on the top of the sliding device 3, a dust brushing mechanism 5 disposed on the inner wall of the support device 2, an inner through groove 6 formed in the inner wall of the support device 2, the input end of the dust suction device 4 extending to the bottom of the inner through groove 6, an electrostatic dust removal mechanism 7 fixedly mounted on the top of the fixed frame 1, a guide assembly 8 fixedly connected to one end of the fixed frame 1, and a mounting hole 9 formed on the top of the fixed frame 1. By placing the dust brushing mechanism 5 inside the support device 2, when... After the paper feeding mechanism delivers the printing paper to the printing equipment, the dust brushing mechanism 5 rotates above the printing paper and contacts its surface to clean and absorb the dust. In conjunction with the sliding device 3, the dust suction device 4 moves above the dust brushing mechanism 5 to suck up the dust. This removes the dust adhering to the surface of the printing paper before it enters the printing area. Furthermore, an electrostatic dust removal mechanism 7 is provided on one side of the support device 2 so that after the printing paper passes under it, the electrostatic dust removal mechanism 7 can perform electrostatic dust removal treatment on its surface, ensuring that the printing paper remains clean during printing and that the cleaning process does not damage the paper or the substrate.

[0027] Please see Figure 2 and Figure 3 The sliding device 3 includes an electric slide rail 301, with a drive motor 302 mounted on the top of the electric slide rail 301. The bottom of the vacuum cleaner 4 is slidably connected to the inside of the electric slide rail 301. By starting the drive motor 302, the electric slide rail 301 is driven to run, thereby causing the vacuum cleaner 4 to move laterally above it. This allows the input end of the vacuum cleaner 4 to move along the inside of the inner groove 6 and move to vacuum near the dust brushing mechanism 5, so that the dust attached to the dust brushing mechanism 5 is sucked out.

[0028] Please see Figure 3 and Figure 5 The vacuuming device 4 includes a vacuum blower 401, a vacuum pipe 402 threadedly connected to the bottom of the vacuum blower 401, a slide 403 fixedly mounted on the bottom of the vacuum blower 401, the slide 403 slidably connected to the inside of the limiting slide 203, a fixed box 404 fixedly connected to the back of the vacuum blower 401, and a guide slider 405 fixedly connected to the bottom of the fixed box 404. By connecting the guide slider 405 to the internal components of the electric slide rail 301, when the electric slide rail 301 is started, it drives the guide slider 405 to slide within it, and at the same time drives the slide 403 to move on the inner wall of the limiting slide 203, thereby providing displacement driving force for the vacuum blower 401, so that it can move back and forth above the dust brushing mechanism 5 in cooperation with the vacuum pipe 402, sucking up the dust attached to the dust brushing mechanism 5, reducing the adhesion and scattering of dust.

[0029] Please see Figure 2 , Figure 3 and Figure 4 The electrostatic dust removal mechanism 7 includes a dust removal frame 701, with an electrostatic dust collector 702 installed on the inner wall of the dust removal frame 701. The electrostatic dust collector 702 is located on one side of the support frame 201. The dust brushing mechanism 5 includes a brush roller 501, with a dust brushing motor 502 fixedly installed at one end of the brush roller 501. The brush roller 501 is located inside the support frame 201. When the printing paper passes under the dust removal frame 701 after the initial dust removal treatment, the electrostatic dust collector 702 is activated, so that the printing paper undergoes electrostatic dust removal again before the paper is conveyed to the printing area, thereby improving the printing quality of the printing paper. The dust brushing motor 502 is activated to drive the brush roller 501 to rotate, so that the soft brush on the brush roller 501 contacts the surface of the printing paper, generating slight friction to remove dust. As the brush roller 501 continues to rotate and change surfaces to ensure that the dust is evenly attached, the dust can be quickly sucked out with the suction pipe 402 to achieve a highly efficient cleaning effect.

[0030] This embodiment provides a paper dust removal device for a printing press. The support frame 201 is fixed to the paper feed channel of the printing equipment. The limiting slide 203 inside the positioning seat 202 provides movement support and limiting for the dust collection components, including the dust collection fan 401 and the slide 403. The brush motor 502 drives the brush roller 501 to rotate and contact the printing paper, adsorbing and removing surface dust. The electric slide rail 301, once activated, drives the guide slider 405 to move laterally back and forth, thus supporting the dust collection fan 401. It provides displacement driving force, enabling it to move back and forth above the brush roller 501 in conjunction with the suction pipe 402. The suction pipe 402 sucks up the dust adhering to the brush roller 501, achieving efficient cleaning by quickly removing the dust and reducing the adhesion and scattering of dust. The soft brush on the surface of the brush roller 501 also reduces friction damage to the paper while removing dust. By activating the electrostatic dust collector 702, the printing paper undergoes electrostatic dust removal again before being conveyed to the printing area, improving the printing quality of the printing paper.

[0031] The working principle of the above embodiments is as follows: The support frame 201 is fixed at the paper feed channel of the printing equipment. The dust brush motor 502 is started to drive the brush roller 501 to rotate, so that the soft brush on the brush roller 501 comes into contact with the surface of the printing paper and generates slight friction to adsorb dust. The drive motor 302 is started to drive the electric slide rail 301 to run and drive the guide slider 405 to slide inside it. At the same time, the slide block 403 moves on the inner wall of the limiting slide 203. The dust suction fan 401 is started to generate suction force inside, and the dust suction pipe 402 moves back and forth above the brush roller 501 to suck out the dust attached to the brush roller 501. At the same time, the electrostatic dust collector 702 is started, so that the printing paper comes into close contact with the electrostatic dust collector 702 after the initial dust removal treatment, so that the printing paper undergoes electrostatic dust removal treatment again before the paper is conveyed to the printing area.
