Description

Technical Field

[0001] The present invention belongs to the technical field of advertising banner machines, and particularly relates to a cleaning method and structure for a print head of a laser ribbon banner machine. Background Art

[0002] A laser ribbon banner machine is a mechanical device used for quickly printing banners in the advertising industry. It can achieve ultra-high-speed printing, with a printing speed of 90 - 180 meters per hour for banners, or even higher, which improves the production efficiency of advertising banners and makes advertising production faster and more convenient. It can not only print on non-coated banner fabrics, but also on other media such as self-adhesive labels, cardboard, and films. In addition, the machine has a ribbon-saving function, which can save 30% - 50% of the ribbon and reduce production costs.

[0003] The print head of a laser ribbon banner machine is an important component of the banner machine, responsible for precisely printing the image or text information on the ribbon onto the material. To ensure printing quality and the normal operation of the device, the cleaning and maintenance of the print head are crucial. Currently, the following methods are generally used for cleaning the print head:

[0004] 1. Before starting the cleaning, turn off the printer and disconnect the printer from the power supply to avoid any possible electric shock risk. At the same time, prepare the required cleaning tools and materials, such as professional cleaning agents, paper towels, cotton swabs, etc.

[0005] 2. According to the specific structure of the device, carefully remove the print head from the printer following the instructions in the operation manual. Special attention should be paid to this step to avoid damaging the print head or other components.

[0006] 3. After diluting the professional cleaning agent according to the ratio in the instruction manual, soak the paper towel or cotton swab, and then gently wipe the surface of the print head. During the cleaning process, avoid using overly strong cleaning agents or excessive force to prevent damage to the print head.

[0007] 4. After the cleaning is completed, reinstall the print head into the printer and perform a test print to ensure that the printing quality has returned to normal.

[0008] The existing above cleaning method requires manual removal of the print head from the printer. There are a large number of guide rollers and connectors inside the printer. By manually removing the print head, there is a risk of damage to the parts. After the print head is cleaned and installed, manual re-adjustment is also required, which greatly affects the work efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0041] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods and in conjunction with the accompanying drawings.

[0042] A method for cleaning a print head of a laser ribbon banner machine comprises the following steps:

[0043] S1. Adjust the clamping sliding frame 3, telescopic rotating shaft 4, fitting and pressing mechanism 6, and scraping mechanism 9 according to the width dimension of the print head 1, and select a cleaning belt 5 with a suitable size to be installed on the telescopic rotating shaft 4 and the fitting and pressing mechanism 6.

[0044] S2. Lift the print head 1 upward to form an installation gap between the print head 1 and the roller 11, and then place the clamping sliding frame 3 into the installation gap. The print head 1 and the roller 11 will clamp and position the clamping sliding frame 3. The top of the clamping sliding frame 3 slides against the print head 1, and the bottom of the clamping sliding frame 3 abuts against the roller 11. After the clamping sliding frame 3 is installed, the fitting and pressing mechanism 6 will be compressed, so that the cleaning surface of the cleaning belt 5 abuts against the print head 1.

[0045] S3. Transport the cleaning liquid to the transmission spraying mechanism 8 through a delivery pump. The transmission spraying mechanism 8 will spray the cleaning liquid onto the cleaning belt 5. When the transmission spraying mechanism 8 sprays, it will drive the telescopic rotating shaft 4 to rotate, and when the telescopic rotating shaft 4 rotates, it will drive the cleaning belt 5 to rotate synchronously.

[0046] S4. When the cleaning belt 5 rotates, the cleaning surface of the cleaning belt 5 will friction-clean the print head 1. Drive the clamping sliding frame 3 to move along the print head 1 and the roller 11 by moving the traction frame 7. When the clamping sliding frame 3 moves, the cleaning belt 5 will friction-clean the surface of the print head 1.

[0047] S5. When the clamping sliding frame 3 moves, the scraping mechanism 9 inside the clamping sliding frame 3 moves synchronously with it. The scraping end of the scraping mechanism 9 will friction against the cleaning surface of the print head 1 to scrape the cleaning liquid on the print head 1.

[0048] S6. When the cleaning belt 5 moves for cleaning, observe the cleaning condition through the camera 2.

[0049] S7. After the print head 1 is cleaned, take out the clamping sliding frame 3.

[0050] The present invention also provides a cleaning structure for a print head of a laser ribbon banner printer for the above-mentioned cleaning method of the print head of a laser ribbon banner printer, including a clamping sliding frame 3 and a delivery pump. A plurality of telescopic rotating shafts 4 are installed inside the clamping sliding frame 3. A fitting and pressing mechanism 6 is also installed between the telescopic rotating shafts 4. A cleaning belt 5 is installed between the telescopic rotating shaft 4 and the fitting and pressing mechanism 6. A scraping mechanism 9 is installed beside the cleaning belt 5. A moving traction frame 7 is installed on the side of the clamping sliding frame 3. A transmission spraying mechanism 8 is installed on the moving traction frame 7. The delivery pump transports the cleaning liquid to the transmission spraying mechanism 8. The spraying end of the transmission spraying mechanism 8 is connected to the inside of the clamping sliding frame 3, and the transmission end of the transmission spraying mechanism 8 is in transmission connection with the telescopic rotating shaft 4. A detection camera 2 is also installed on the side of the clamping sliding frame 3.

[0051] The clamping and sliding frame 3 includes an installation track 31 and a sliding adjustment track 32 that are spliced with each other. A sliding sealing edge is provided at the connection between the installation track 31 and the sliding adjustment track 32. A plurality of sliding installation grooves 321 are provided on the inner walls of both the installation track 31 and the sliding adjustment track 32. The sliding installation grooves 321 are used to install the fitting and pressing mechanism 6. A first adjustment screw rod 33 is installed between the installation track 31 and the sliding adjustment track 32. One end of the first adjustment screw rod 33 is rotatably connected to the sliding adjustment track 32, and the other end is threadedly connected to the installation track 31. Sliding clamping corners 35 are respectively provided at both side ends of the installation track 31 and the sliding adjustment track 32. A sliding clamping strip 34 is provided at the bottom of the installation track 31 and the sliding adjustment track 32.

[0052] When it is necessary to clean the print head 1 after the print head 1 of the laser ribbon banner machine has worked for a long time, according to the width dimension of the print head 1, the first adjustment screw rod 33 is rotated. When the first adjustment screw rod 33 rotates, it will adjust the distance between the installation track 31 and the sliding adjustment track 32. The sliding sealing edge between the installation track 31 and the sliding adjustment track 32 is used to ensure the sealing performance of the connection. When the installation track 31 and the sliding adjustment track 32 adjust the distance, they can be adapted to be clamped between the print head 1 and the roller 11. After the installation track 31 and the sliding adjustment track 32 are adjusted, then the telescopic rotating shaft 4, the fitting and pressing mechanism 6 and the scraping mechanism 9 are adjusted. A cleaning belt 5 of a suitable size is selected and installed on the telescopic rotating shaft 4 and the fitting and pressing mechanism 6. After the cleaning belt 5 is installed, the print head 1 is lifted upward to form an installation gap between the print head 1 and the roller 11. Then the adjusted installation track 31 and sliding adjustment track 32 are placed into the installation gap. The sliding clamping corners 35 at the top of the installation track 31 and the sliding adjustment track 32 will be limited and clamped to the bottom of the print head 1. The sliding clamping strip 34 at the bottom of the installation track 31 and the sliding adjustment track 32 abuts against the roller 11. Pulleys are installed on both the sliding clamping corners 35 and the sliding clamping strip 34, which can effectively reduce the friction force of the sliding clamping corners 35 and the sliding clamping strip 34, so that the installation track 31 and the sliding adjustment track 32 can slide and adjust between the print head 1 and the roller 11. The movement of the installation track 31 and the sliding adjustment track 32 can drive the cleaning surface of the cleaning belt 5 to frictionally clean the print head 1, effectively adapting to be installed on print heads 1 of different sizes.

[0053] The telescopic rotating shaft 4 includes a first fixed rotating shaft 41 and a first telescopic rotating shaft 42 installed between the installation track 31 and the sliding adjustment track 32. A docking groove 421 is provided at the end of the first telescopic rotating shaft 42. Anti-slip surfaces 43 are provided on the outer walls of the first fixed rotating shaft 41 and the first telescopic rotating shaft 42. One end of the first fixed rotating shaft 41 is rotatably connected to the sliding adjustment track 32, and the other end is slidably connected to the first telescopic rotating shaft 42. A second adjustment screw rod 44 that is in clearance fit with the first fixed rotating shaft 41 is penetrated through the first fixed rotating shaft 41. The inner end of the second adjustment screw rod 44 is threadedly connected to the first telescopic rotating shaft 42.

[0054] When rotating and adjusting the first adjustment screw rod 33 according to the width dimension of the print head 1, the distance between the installation track 31 and the sliding adjustment track 32 will be adjusted when the first adjustment screw rod 33 rotates. After the installation track 31 and the sliding adjustment track 32 are adjusted, the cleaning operator then installs the cleaning belt 5 and the fitting pressing mechanism 6 into the installation track 31 and the sliding adjustment track 32. The cleaning belt 5 will be sleeved on the outside of the telescopic rotating shaft 4. Subsequently, the cleaning operator rotates the second adjustment screw rod 44. When the second adjustment screw rod 44 rotates, it will drive the first telescopic rotating shaft 42 to perform telescopic movement on the first fixed rotating shaft 41. When the first telescopic rotating shaft 42 extends, the docking groove 421 will be in transmission connection with the transmission spraying mechanism 8. When the cleaning liquid is conveyed to the transmission spraying mechanism 8 through the delivery pump, the transmission spraying mechanism 8 will spray the cleaning liquid onto the cleaning belt 5. When the transmission spraying mechanism 8 sprays, it will drive the telescopic rotating shaft 4 to rotate. When the telescopic rotating shaft 4 rotates, the anti-slip surface 43 will drive the cleaning belt 5 to rotate synchronously. The telescopic rotating shaft 4 can effectively ensure the transmission effect.

[0055] A plurality of strip-shaped anti-slip grooves 51 are distributed on the inner wall of the cleaning belt 5. A plurality of flow holes are provided inside the strip-shaped anti-slip grooves 51. A flexible cleaning layer 52 is provided on the outer wall of the cleaning belt 5.

[0056] When the cleaning liquid is conveyed to the transmission spraying mechanism 8 through the delivery pump, the transmission spraying mechanism 8 will spray the cleaning liquid onto the inner wall of the cleaning belt 5. The strip-shaped anti-slip grooves 51 on the cleaning belt 5 can effectively and evenly guide the flow of the cleaning liquid. The flow holes inside the strip-shaped anti-slip grooves 51 can effectively make the cleaning liquid evenly penetrate onto the flexible cleaning layer 52 on the outer wall of the cleaning belt 5. At the same time, the strip-shaped anti-slip grooves 51 are used to cooperate with the anti-slip surface 43 on the telescopic rotating shaft 4 to increase the friction force, so that when the telescopic rotating shaft 4 rotates, it will drive the cleaning belt 5 to rotate effectively synchronously. When the cleaning belt 5 rotates, the flexible cleaning layer 52 can effectively friction-clean the print head 1.

[0057] The fitting pressing mechanism 6 includes an elastic pressing mechanism 61 opened on the sliding installation groove 321. The fitting pressing mechanism 6 further includes a pressing adjustment shaft 62 installed at the end in the sliding installation groove 321. The pressing adjustment shaft 62 is used to press the cleaning belt 5.

[0058] The elastic pressing mechanism 61 includes limiting guide rails opened on both sides of the sliding installation groove 321, and a compression spring is connected to the bottom of the sliding installation groove 321.

[0059] The cleaning belt 5 is sleeved on the telescopic rotating shaft 4. The pushing and adjusting shaft 62 is arranged inside the cleaning belt 5, and both ends of the pushing and adjusting shaft 62 are respectively installed inside the sliding installation groove 321. When the pushing and adjusting shaft 62 is installed into the sliding installation groove 321, the compression spring resets and pushes the pushing and adjusting shaft 62 to move upward. When the pushing and adjusting shaft 62 moves upward, it will push the cleaning belt 5 to move upward. When the clamping sliding frame 3 is placed on the print head 1 and the roller 11, the pushed cleaning belt 5 closely abuts against the bottom of the print head 1.

[0060] The pushing and adjusting shaft 62 includes a second fixed rotating shaft 622 and a second telescopic rotating shaft 623 connected by plugging. Sliding blocks 621 are connected to the ends of the second fixed rotating shaft 622 and the second telescopic rotating shaft 623. The sliding blocks 621 are slidably matched with the sliding installation groove 321, and limiting ear plates slidably matched with the limiting guide rails are integrally formed on both sides of the sliding blocks 621. Limiting card slots 624 are evenly opened on the outer peripheral surfaces of the second fixed rotating shaft 622 and the second telescopic rotating shaft 623, and elastic rings 625 are installed on the limiting card slots 624.

[0061] The second fixed rotating shaft 622 and the second telescopic rotating shaft 623 can be pulled and adjusted for stretching. The elastic rings 625 are movably clamped in the limiting card slots 624. Since the bottom of the print head 1 is uneven, in order to ensure that the cleaning surface of the cleaning belt 5 fits and cleans the bottom of the print head 1, the cleaning operator installs the elastic rings 625 in the appropriate limiting card slots 624 according to the shape of the bottom of the print head 1. By pushing the cleaning belt 5 with the elastic rings 625, the cleaning belt 5 can effectively adapt to abut against different-shaped cleaning surfaces, effectively ensuring the cleaning effect of the cleaning belt 5.

[0062] The moving traction frame 7 includes a connecting bracket 71 installed on the side of the clamping sliding frame 3, and a transfer handle 72 is installed on the connecting bracket 71.

[0063] An installation channel is provided inside the transfer handle 72. When the cleaning belt 5 rotates, the cleaning surface of the cleaning belt 5 will friction-clean the print head 1. The cleaning operator can drive the connecting bracket 71 to move through the transfer handle 72. When the connecting bracket 71 moves, it can drive the clamping sliding frame 3 to slide. The connecting bracket 71 and the transfer handle 72 can be rotated and adjusted. The rotation and adjustment of the transfer handle 72 and the connecting bracket 71 are convenient for avoiding the roller 11 inside the banner machine, and can cooperate with the cleaning personnel to push, effectively improving the adaptability of pushing the clamping sliding frame 3 to move. The installation channel inside the transfer handle 72 is convenient for installing a connecting pipe, and the connecting pipe is connected to a delivery pump.

[0064] The transmission and spraying mechanism 8 includes a transmission spray water pipe 81 and a water outlet head 82 installed on the connection bracket 71. Both the transmission spray water pipe 81 and the water outlet head 82 are internally communicated with the inside of the clamping sliding frame 3. A rotating joint 811 is installed at the front end of the transmission spray water pipe 81, and rotating blades are installed inside the rotating joint 811. The transmission spray water pipe 81 further includes a docking transmission shaft 812 installed beside the rotating joint 811. Transmission gears that mesh with each other are installed on the docking transmission shaft 812 and the rotating joint 811. The docking transmission shaft 812 is inserted and cooperated with the docking groove 421 in the telescopic rotating shaft 4 to achieve transmission connection.

[0065] The cleaning liquid is transported into the transmission spray water pipe 81 by a delivery pump. When the transmission spray water pipe 81 transports the cleaning liquid, the cleaning liquid will pass through the rotating joint 811 and enter the inside of the clamping sliding frame 3. The cleaning liquid that enters the inside of the clamping sliding frame 3 will seep into the cleaning belt 5. When the cleaning liquid passes through the rotating blades, the rotating blades will rotate under the influence of the water flow. When the rotating blades rotate, the rotating joint 811 will rotate accordingly. When the rotating joint 811 rotates, it drives the docking transmission shaft 812 to rotate synchronously through the transmission gears. The docking transmission shaft 812 is docked with the docking groove 421 of the telescopic rotating shaft 4. When the docking transmission shaft 812 rotates, it drives the telescopic rotating shaft 4 to rotate synchronously. The telescopic rotating shaft 4 can then drive the cleaning belt 5 to rotate synchronously, effectively saving driving energy. At the same time, the water outlet head 82 is connected to another delivery pump. When the transmission spray water pipe 81 transports the cleaning liquid, the other delivery pump can cooperate with the water outlet head 82 to suck the cleaning liquid inside the clamping sliding frame 3 to form a circulating spraying and cleaning.

[0066] The scraping mechanism 9 includes two mounting blocks 91 installed on both sides inside the clamping sliding frame 3. A plurality of mounting slots are symmetrically opened on the two mounting blocks 91, and elastic scraping strips are jointly installed in the mounting slots corresponding in position on the two mounting blocks 91.

[0067] When the cleaning belt 5 rotates, the cleaning surface of the cleaning belt 5 will frictionally clean the print head 1. By moving the traction frame 7 to drive the clamping sliding frame 3 to move along the print head 1 and the roller 11, when the clamping sliding frame 3 moves, the cleaning belt 5 will frictionally clean the surface of the print head 1. When the clamping sliding frame 3 moves, it will also drive the mounting blocks 91 to move synchronously. The mounting slots of the mounting blocks 91 are used to install a plurality of elastically arranged scraping strips. The elastic scraping strips on the mounting blocks 91 can effectively scrape the cleaning liquid on the print head 1 and improve the cleaning effect.

[0068] In the present invention, the technical features not described can be realized by the prior art and will not be elaborated here. The present invention is not limited to the above specific embodiments. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the essence of the present invention should also fall within the protection scope of the present invention.

When the docking transmission shaft (812) rotates, it drives the telescopic rotating shaft (4) to rotate synchronously, and the telescopic rotating shaft (4) can drive the cleaning belt (5) to rotate synchronously, effectively saving driving energy. At the same time, the water outlet head (82) is connected to another transfer pump. When the transmission water spray pipe (81) conveys the cleaning liquid, the other transfer pump can cooperate with the water outlet head (82) to suck the cleaning liquid inside the clamping sliding frame (3) to form a circulating spraying and cleaning; S4. When the cleaning belt (5) rotates, the cleaning surface of the cleaning belt (5) frictionally cleans the print head (1). The moving traction frame (7) drives the clamping sliding frame (3) to move along the print head (1) and the roller (11). When the clamping sliding frame (3) moves, the cleaning belt (5) frictionally cleans the surface of the print head (1); S5. When the clamping sliding frame (3) moves, the scraping mechanism (9) inside the clamping sliding frame (3) moves synchronously with it. The scraping end of the scraping mechanism (9) rubs against the cleaning surface of the print head (1) to scrape the cleaning liquid on the print head (1). S6. When the cleaning belt (5) moves for cleaning, the cleaning condition is observed through the detection camera (2). S7.
