Description

Technical Field

[0001] This application relates to printing equipment, and more particularly to a printing equipment with a dust removal function. Background Technology

[0002] With the development of high-speed printing technology, the requirements for dust removal efficiency and effectiveness are getting higher and higher. In the printing industry, dust and impurities on the surface of materials will directly affect the printing quality. In the printing industry, printing equipment with dust removal function is a professional equipment that can effectively remove dust, fibers and other impurities from the surface of paper during the printing process by integrating a dust removal system.

[0003] A search revealed Chinese Patent Publication No. CN211363950U, which discloses a printing device with a dust removal function. The device includes a printing box body, with a second electric push rod fixedly installed on the inner top wall of the printing box body. A second printing roller is fixedly installed at the bottom end of the second electric push rod. This dust-removing printing device uses a first electric push rod to drive a third electric push rod and brushes downwards. Then, the third electric push rod drives the brushes left and right, causing the two brushes to contact the surfaces of the first and second printing rollers respectively. The brushes then brush away the dust from their surfaces, causing it to fall into a dust collection hood. A fan is then activated to prevent the dust from falling onto the inner bottom wall of the printing box body and causing contamination. After cleaning, the first electric push rod drives the brushes upwards to prevent them from obstructing the printing operation. This achieves a simple structure, convenient use, and superior dust removal effect.

[0004] Although the above patent describes the process: In use, paper is fed through the feed inlet 11 between the first printing roller 10 and the second printing roller 12. At this time, the first printing roller 10 performs single-sided printing. When double-sided printing is required, the second electric push rod 16 is activated, which drives the second printing roller 12 downwards for double-sided printing. Then, the printed paper is guided through the guide roller 2 between the first pressure roller 7 and the second pressure roller 9, where it is pressed and shaped to prevent wrinkles. Finally, it is discharged through the discharge outlet 8. When dust removal is required for the first printing roller 10 and the second printing roller 12, the first electric push rod 13 is activated, which drives the third electric push rod 18 and the brush 15 downwards. Then, the third electric push rod 18 drives the brush 15 to move left and right, so that the two brushes 15 respectively interact with the first printing roller 10 and the second printing roller 12. The surfaces of the brush roller 10 and the second printing roller 12 come into contact. At this time, the dust on the surface is brushed downward by the brush 15 and falls into the dust collection hood 6. Then, the exhaust fan 4 is started, and the dust falling downward and falling into the dust collection hood 6 is sucked into the dust collection box 3 for collection through the exhaust fan 4 and the exhaust pipe 5, so as to prevent it from falling into the inner bottom wall of the printing box body 1 and causing pollution. After cleaning, the brush 15 is moved upward by the first electric push rod 13 to avoid it from hindering the printing operation. This achieves the purpose of simple structure, convenient use and better dust removal effect. However, the above description cannot combine the use of double-sided dust removal and quick paper replacement, which results in uneven printing, blurry patterns, reduced quality of printed products and reduced service life of equipment. Therefore, a printing equipment with dust removal function is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0036] Example: A printing device with dust removal function, referring to... Figure 1 , Figure 3 and Figure 5 The system includes a support transmission frame 1, which serves as the basic support structure for the entire printing equipment. This provides a stable platform for the transport of the cardboard 2, ensuring the orderly operation of the entire printing equipment and preventing problems such as cardboard 2 shifting or component loosening due to unstable support. This guarantees printing quality and the normal service life of the equipment. A double-sided dust removal mechanism 3 is installed on the top of the support transmission frame 1. The double-sided dust removal mechanism 3 includes U-shaped support columns 31, which serve as the support frame for the double-sided dust removal mechanism 3. These columns are fixed to both sides of the support transmission frame 1, providing a mounting base for components such as the drive assembly 33 and the dust collection assembly 38. Multiple entry holes 32 on the top provide channels for dust to enter the dust collection assembly 38. The bottom of the U-shaped support column 31 is fixedly connected to... On both sides of the support transmission frame 1, the top of the U-shaped support column 31 is provided with multiple inlet holes 32. The inlet holes 32 serve as the entrance for dust to enter the dust collection component 38, guiding the dust generated by the double-sided dust removal mechanism 3 when cleaning the dust on the surface of the cardboard 2, so that it can smoothly enter the dust collection component 38 for collection. The top of the U-shaped support column 31 is fixedly connected to the drive component 33, which includes a drive motor 3301. The drive motor 3301 serves as the power source for the double-sided dust removal mechanism 3, providing rotational power to the entire drive component 33. Through the drive end, it drives the support disc 3302 to rotate, thereby realizing the dust removal action of the connecting rubber plate 35 and the connecting scraper 36 on the surface of the cardboard 2. The external of the drive motor 3301 is fixedly connected to the inner side of the top of the U-shaped support column 31.

[0037] Specifically, when the printing equipment with dust removal function is running, the drive motor 3301 starts, serving as the power source for the double-sided dust removal mechanism 3. Through its drive end, it drives the support disc 3302 to rotate. The support disc 3302 drives the connecting rubber plate 35 and the connecting scraper 36 to perform dust removal on the surface of the cardboard 2 placed on the support conveyor frame 1. The connecting rubber plate 35, through flexible contact, effectively adsorbs and initially removes dust from the surface of the cardboard 2, while the connecting scraper 36 removes stubborn dust. Dust generated during the dust removal process enters the dust suction component 38 through multiple inlet holes 32 at the top of the U-shaped support column 31. The dust suction component 38 uses suction to draw in and collect the dust, thus completing the dust removal work on both sides of the cardboard 2. The support conveyor frame 1 stably transports the cardboard 2, and all components of the double-sided dust removal mechanism 3 work together to achieve efficient dust removal, ensuring the smooth progress of subsequent printing processes.

[0038] A support disc 3302 is fixedly connected to the drive end of the drive motor 3301, serving as a transmission component between the drive motor 3301 and the cylinder 3303. This disc transmits the rotational power of the drive motor 3301 to the cylinder 3303 and provides mounting support for the cylinder 3303, ensuring its stability during rotation. The cylinder 3303 is fixedly connected to the bottom of the support disc 3302. Through its telescopic movement, the cylinder 3303 drives the rotating plate 34 to move up and down and rotate, thereby adjusting the distance and angle between the connecting rubber plate 35 and the connecting scraper 36 and the surface of the cardboard 2. This allows them to better adhere to the surface of the cardboard 2, improving the dust removal effect. The output end of the cylinder 3303 is fixedly connected to the rotating disc 3302. At the top of plate 34, a support connecting shell 3304 is fixedly connected to the outside of the drive motor 3301. The support connecting shell 3304 protects the drive motor 3301, preventing dust, debris, etc. from entering the motor and affecting its normal operation. At the same time, it provides a support structure for the drive motor 3301 to be installed and fixed, ensuring the stability of the motor during operation. At the bottom of the drive assembly 33, a rotating plate 34 is fixedly connected. The rotating plate 34 serves as an intermediate component connecting the cylinder 3303, the connecting rubber plate 35, and the connecting scraper 36. It transmits the extension and rotation of the cylinder 3303 to the connecting rubber plate 35 and the connecting scraper 36, and provides an installation platform for the connecting rubber plate 35 and the connecting scraper 36.

[0039] Specifically, after the drive motor 3301 starts, its drive end drives the fixedly connected support disc 3302 to rotate. The support disc 3302 transmits the rotational power to the cylinder 3303 fixedly connected at the bottom. The cylinder 3303 starts to operate and, through telescopic movement, drives the rotating plate 34 fixedly connected to its output end to move up and down and rotate. The rotating plate 34, as an intermediate component, transmits the movement of the cylinder 3303 to the connecting rubber plate 35 and the connecting scraper 36 fixed on it, so that they change the distance and angle with the surface of the cardboard 2 according to the movement of the rotating plate 34. Throughout the process, the support connecting shell 3304 outside the drive motor 3301 provides protection and fixed support for the motor, ensuring stable operation of the motor, and finally realizing the effective dust removal operation of the connecting rubber plate 35 and the connecting scraper 36 on the surface of the cardboard 2.

[0040] Two elastic fastening straps 37 are fixedly connected to the bottom of the rotating plate 34. The elastic fastening straps 37 enable quick installation and removal between the connecting rubber plate 35 and the rotating plate 34, facilitating the replacement and maintenance of the connecting rubber plate 35. The connecting rubber plate 35 is slidably connected to the bottom of the rotating plate 34. The connecting rubber plate 35 utilizes its own elasticity and the rubber material on its surface to perform preliminary dust removal on the surface of the cardboard 2. Through close contact with the surface of the cardboard 2, it adsorbs and wipes away dust, while providing an installation base for the connecting scraper 36. The connecting scraper 36 then removes stubborn dust and debris. The connecting rubber plate 35 is fixedly connected to the right side of the connecting scraper 36, which scrapes away stubborn dust and impurities on the surface of the cardboard 2 with its sharp edge. Together with the connecting rubber plate 35, it achieves deep dust removal on the surface of the cardboard 2, ensuring that there is no residual dust and impurities on the surface of the cardboard 2. The bottom of the supporting transmission frame 1 is fixedly connected to the dust collection assembly 38, which includes two inlet pipes 3803. The top of the two inlet pipes 3803 is fixedly connected to the bottom of the connecting pipe 3802. The bottom of the supporting transmission frame 1 is fixedly connected to the supporting collection box 3801.

[0041] Specifically, when the device is working, the elastic fastening band 37 at the bottom of the rotating plate 34 quickly installs and fixes the connecting rubber plate 35 to the bottom of the rotating plate 34. When the cardboard 2 is conveyed on the support conveyor frame 1, the connecting rubber plate 35 uses its own elasticity and rubber material to tightly adhere to the surface of the cardboard 2, and performs preliminary dust removal on the cardboard 2 through adsorption and wiping. The connecting scraper 36 connected to the right side of the connecting rubber plate 35, with its sharp edge, scrapes off stubborn dust and impurities from the surface of the cardboard 2, and together with the connecting rubber plate 35, completes deep dust removal. The dust collection component 38 at the bottom of the support conveyor frame 1 starts to operate. The two inlet pipes 3803 in the dust collection component 38 collect the dust raised after being processed by the connecting rubber plate 35 and the connecting scraper 36, and transport the dust to the connecting pipe 3802 through the inlet pipes 3803, and finally guide it into the support collection box 3801, realizing the dust removal and dust collection of the cardboard 2.

[0042] The support collection box 3801 serves as a dust collection container for the vacuuming assembly 38, storing dust and impurities extracted by the vacuum pump 3804. It also provides mounting support for other vacuuming components, ensuring the overall stability of the vacuuming system. The bottom of the support collection box 3801 is fixedly connected to the vacuum pump 3804, which acts as the power core of the vacuuming assembly 38. By generating strong suction, the vacuum pump 3804 draws the dust and impurities removed from the surface of the cardboard 2 through the connecting pipe 3802 and the inlet pipe 3803 into the outlet pipe 3806, ultimately sending them into the support collection box 3801 for collection. The inlet end of the vacuum pump 3804 is fixedly connected to the inside of the inlet pipe 3803, which serves as a connection... The transition pipe between pipe 3802 and output pipe 3806 increases the number of channels for dust to enter output pipe 3806, improving dust collection efficiency. It also plays a certain role in diverting and guiding the flow, allowing dust to enter output pipe 3806 evenly. The output end of dust pump 3804 is fixedly connected to collection pipe 3805, and the bottom of collection pipe 3805 is fixedly connected to output pipe 3806. Output pipe 3806 serves as the main pipe for dust transmission, connecting dust pump 3804 and support collection box 3801. It transports the dust and impurities extracted by dust pump 3804 to support collection box 3801 for storage, while also playing a certain role in buffering and stabilizing airflow to ensure the stability of dust transmission.

[0043] Specifically, during the operation of the vacuuming assembly 38, after the dust pump 3804, as the power core, is started, it generates a strong suction. The dust and impurities removed from the surface of the cardboard 2 first enter the inlet pipe 3803 through the connecting pipe 3802. The inlet pipe 3803 serves as a transition pipe, increasing the number of dust entry channels. After the dust is collected through this pipe, it is sucked into the pump from the inlet end of the dust pump 3804. The dust pump 3804 pressurizes and transmits the dust, causing it to enter the output pipe 3806 from the output end through the collection pipe 3805. The output pipe 3806 serves as the main dust transmission pipe, transporting the dust and impurities extracted by the dust pump 3804 to the support collection box 3801. The support collection box 3801 serves as a dust collection container, used to store the dust and impurities extracted by the dust pump 3804.

[0044] Multiple rubber blocks 39 are fixedly connected to the bottom of the connecting rubber plate 35 to increase the friction between the connecting rubber plate 35 and the surface of the cardboard 2, allowing the connecting rubber plate 35 to better fit the surface of the cardboard 2. Simultaneously, they provide a buffering effect when the connecting rubber plate 35 contacts the surface of the cardboard 2, preventing scratches. A connecting pipe 3802 is fixedly connected to the top of the supporting transmission frame 1. The connecting pipe 3802 serves as a dust transmission conduit, guiding dust entering from the inlet hole 32 to the outlet pipe 3806. Adsorption mechanisms 4 are provided on both sides of the supporting transmission frame 1. The top of the support conveyor frame 1 is slidably connected to the cardboard 2. The cardboard 2 serves as the printing object, carrying the final printed graphic information. At the same time, during the operation of the equipment, it removes surface dust and impurities through contact with various dust removal components, laying the foundation for high-quality printing. Driven by the support conveyor frame 1, the cardboard 2 moves along a fixed conveying path, passing through the double-sided dust removal mechanism 3 and the adsorption mechanism 4 in sequence. During the movement, the dust and impurities on its surface are removed by the corresponding dust removal structures. Then it enters the laser printer 5 for graphic printing, and finally the output machine 6 outputs the finished product.

[0045] Specifically, during operation, the support conveyor 1 drives the cardboard 2 to move along a fixed conveying path. The cardboard 2 first passes through the double-sided dust removal mechanism 3. Multiple rubber blocks 39 at the bottom of the connecting rubber plate 35 on its surface contact the surface of the cardboard 2. Under the action of the support conveyor 1, the connecting rubber plate 35 can adhere to the surface of the cardboard 2. At the same time, the connecting pipe 3802 guides the dust entering from the inlet hole 32 to the outlet pipe 3806. Next, the cardboard 2 moves to the adsorption mechanism 4 on both sides of the support conveyor 1. The adsorption mechanism 4 further removes the dust and impurities remaining on the surface of the cardboard 2. After the dust removal is completed, the cardboard 2 enters the laser printer 5. The laser printer 5 prints the graphic information onto the cardboard 2. Finally, the printed cardboard 2 is output by the output machine 6 to form the finished product.

[0046] Reference Figure 2 , Figure 4 and Figure 6The adsorption mechanism 4 includes two support plates 41. The support plates 41 serve as the basic support components of the adsorption mechanism 4, fixed to both sides of the bottom of the support transmission frame 1. They provide a stable mounting platform for components such as the support collection box 42 and the adsorption plate 43, while also guiding dust into the adsorption area. This is the fundamental guarantee for the operation of the entire adsorption mechanism 4. The adjacent sides of the two support plates 41 are fixedly connected to the bottom sides of the support transmission frame 1. The support collection box 42 is slidably connected to the top of the support plates 41. The support collection box 42 is used to accommodate the adsorption plate 43, collecting the dust and impurities adsorbed by the adsorption plate 43. It serves as a dust storage container and can slide on top of the support plates 41 for easy cleaning and maintenance. The adsorption plate 43 is slidably connected inside the support collection box 42. The adsorption plate 43 utilizes its own adsorption properties to adsorb dust falling into the top area of ​​the support plate 41. The adsorption mechanism 4 is the core component for dust and impurities to achieve dust removal, ensuring that dust does not spread and improving the cleanliness of the cardboard 2 surface. A connecting plate a44 is fixedly connected to one side of the support plate 41. A limiting cylinder 47 is fixedly connected to one side of the two connecting plates a44. The supporting plate 41 and the limiting cylinder 47 are connected to each other, which serves to fix and transmit force, ensuring that the limiting cylinder 47 maintains a stable position in the adsorption mechanism 4. At the same time, it provides guidance for the sliding of the limiting cylinder 47. A connecting plate b46 is fixedly connected to the inside of both sides of the support transmission frame 1. The connecting plate b46 serves as the installation base for the supporting limiting column 45. It is fixed inside both sides of the support transmission frame 1, providing stable support for the supporting limiting column 45 and ensuring that the supporting limiting column 45 remains fixed during equipment operation, thereby ensuring the stable operation of the entire limiting and elastic system.

[0047] Specifically, when the adsorption mechanism 4 is working, the support plates 41 on both sides of the bottom of the support transmission frame 1 provide basic support. When the cardboard 2 with dust and impurities passes by, the dust falls into the top area of ​​the support plate 41. At this time, the adsorption plate 43 uses its own adsorption properties to adsorb the dust and impurities, preventing them from spreading. The adsorption plate 43 is located inside the support collection box 42, and the adsorbed dust and impurities are then collected in the support collection box 42. When a certain amount of dust is collected in the support collection box 42, it can be removed for cleaning by sliding the support collection box 42 on the top of the support plate 41. During the process, the connecting plate a44 and the connecting plate b46 provide the installation and fixing base for the limiting cylinder 47 and the support limiting column 45, respectively, to ensure that the positions of the limiting cylinder 47 and the support limiting column 45 are stable, and to ensure that the components of the adsorption mechanism 4 work together to continuously and effectively remove dust from the surface of the cardboard 2.

[0048] Multiple support limiting posts 45 are fixedly connected to the opposite side of the connecting plate b46. The support limiting post 45 is designed with a cavity and slide that are adapted to the limiting connecting ball 48 and the elastic component 49. The limiting connecting ball 48 can slide along the slide inside. The elastic component 49 is installed in a specific position. When the limiting cylinder 47 interacts with the limiting connecting ball 48, the support limiting post 45 provides stable support and motion guidance to ensure that the limiting and elastic functions are normal. The limiting connecting ball 48 is slidably connected inside the support limiting post 45. The limiting connecting ball 48 and the limiting cylinder 47 cooperate to realize the limiting function of the supporting collection box 42. At the same time, during the sliding process of the supporting collection box 42, the interaction with the elastic component 49 buffers and dampens the sliding of the supporting collection box 42 to ensure that the supporting collection box 42 slides smoothly. The elastic component 49 is slidably connected inside the support limiting post 45.

[0049] Specifically, when the support collection box 42 slides, the limiting cylinder 47 that cooperates with the support collection box 42 interacts with the limiting connecting ball 48 inside the support limiting post 45. Since the limiting ball 48 is used inside the support limiting post 45, it can slide within the slide. The limiting cylinder 47 pushes the limiting connecting ball 48 to move along the slide, thereby limiting and guiding the support collection box 42. During the sliding process of the support collection box 42, the limiting connecting ball 48 will compress the elastic component 49 installed at a specific position inside the support limiting post 45. The elastic component 49 is compressed and deformed. When the external force of the support collection box 42 sliding weakens, the elastic component 49 will gradually recover its deformation and generate a reverse force, which buffers and dampens the sliding of the support collection box 42. Through the synergistic effect of the limiting connecting ball 48, the elastic component 49 and the support collection box 42, the support collection box 42 is ensured to slide smoothly within the support limiting post 45.

[0050] The elastic component 49 includes multiple telescopic springs 4901. As the core elastic component of the elastic component 49, the telescopic springs 4901 generate elastic force through their own expansion and contraction, providing buffering force for the limiting connecting ball 48, buffering and damping the sliding of the supporting collection box 42, and assisting the limiting connecting ball 48 in resetting during the installation and disassembly of the supporting collection box 42. The external surfaces of the multiple telescopic springs 4901 are slidably connected to the inside of the supporting limiting post 45. A telescopic post 4902 is fixedly connected to the inner wall of the supporting limiting post 45, guiding and limiting the telescopic springs 4901, ensuring that the telescopic springs 4901 can expand and contract in the correct direction, and enhancing the structural stability of the elastic component 49. The inner side of the telescopic springs 4901 is sleeved and connected to the outside of the telescopic post 4902. The external surface of each limiting cylinder 47 is slidably connected to the adjacent side of two limiting connecting balls 48. The connecting ball 48, in conjunction with the support, limits the sliding of the support collection box 42, preventing it from falling off the support plate 41. It also guides the sliding of the support collection box 42, ensuring an accurate sliding path. The bottom of the connecting scraper 36 is slidably connected to the bottom of multiple rubber blocks 39 on the top of the cardboard 2. A laser printer 5 is fixedly connected to the right side of the support transmission frame 1. As the core printing component of the printing equipment, the laser printer 5 transfers the graphic information from the electronic document onto the surface of the dust-removed cardboard 2 using laser scanning imaging technology, achieving high-accuracy printing. It is a key device for completing the printing task. An output machine 6 is fixedly connected to the right side of the laser printer 5, outputting the cardboard 2 printed by the laser printer 5, sorting and stacking the printed products for user collection and subsequent processing. This is the final step in the printing process, ensuring the smooth delivery of the printed products.

[0051] Specifically, the laser printer 5, as the core printing component, transfers the graphic information in the electronic document onto the surface of the dust-free cardboard 2 using laser scanning imaging technology, achieving high-accuracy printing. The printed cardboard 2 is then sorted, stacked, and output by the output machine 6. After the cardboard 2 is output, the bottom of the connecting scraper 36 and the bottom of multiple rubber blocks 39 contact the top of the cardboard 2 to process the surface of the cardboard 2. At the same time, the support collection box 42 slides along the support plate 41. The limiting cylinder 47 and the limiting connecting ball 48 cooperate to limit and guide the sliding of the support collection box 42. When the support collection box 42 slides, the telescopic spring 4901 in the elastic component 49 expands and contracts within the support limiting column 45. The telescopic column 4902 guides and limits the telescopic spring 4901. The telescopic spring 4901 provides buffering force for the limiting connecting ball 48, buffering and damping the sliding of the support collection box 42, ensuring the smooth operation of the entire printing output process.

[0052] The implementation principle of this application embodiment is as follows: First, when the cardboard 2 is placed on the support conveyor frame 1 for conveying, the drive motor 3301 is started, thereby driving the support disc 3302 to rotate, thereby causing the cylinder 3303 to extend and retract, thereby driving the rotating plate 34 to rotate and extend, so that the bottom connecting rubber plate 35 is quickly replaced by the elastic fastening belt 37, thereby the connecting rubber plate 35 removes dust from the top, and stubborn dust is scraped off by the connecting scraper 36, thereby activating the bottom output pipe 3806 to provide power during the conveying process. In this process, dust is extracted by the dust pump 3804 and enters the output pipe 3806 through the connecting pipe 3802 and two inlet pipes 3803, thus entering the interior of the support collection box 3801. This allows the cardboard 2 to be cleaned of dust on both sides. As the dust on the cardboard 2 is reduced, the amount of dust entering the printing area inside the equipment is reduced, thereby reducing the occurrence of problems such as uneven printing and blurred patterns caused by dust. This effectively improves the quality of the printed products and extends the service life of the production equipment.

[0053] Secondly, when cleaning dust from the top of the cardboard 2, the dust enters the interior of the support plates 41 on both sides and is adsorbed by the adsorption plates 43, along with surface impurities. The support plates 41 support the collection box 42, and when the collection box 42 is pulled, the limiting cylinder 47 slides. As the limiting cylinder 47 slides, it squeezes the limiting connecting balls 48 on both sides, causing the telescopic spring 4901 and telescopic column 4902 to extend and retract inside the supporting limiting column 45. This allows the support plate 41 to be cleaned quickly. During installation, it is pushed, and the limiting connecting balls 48 limit and fix the limiting cylinder 47. This makes the operation convenient and stable, saves cleaning and installation time, and reduces the difficulty of cleaning, maintenance, installation, and disassembly.
