Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a printing mechanism of a flexographic printing press. Background Art

[0002] Flexographic printing presses use highly fluid inks. The ink is transferred to the image and text portion of the printing plate by the ink fountain rubber roller and the anilox roller, and then the pressure roller applies printing pressure to transfer the ink from the printing plate to the substrate. Finally, the printing process is completed by drying the surface. The main principle of the doctor blade inside the printing press is to use the pressure between the doctor blade and the printing plate to scrape off the excess ink on the printing plate, ensuring that only the required parts are covered by ink during the printing process. However, the removal process of the doctor blade in some existing printing presses is relatively complicated.

[0003] The utility model with authorization announcement number CN 214821693 U discloses a printing mechanism for a stacked flexographic printing press, comprising a main body; a plate roller, the plate roller being disposed on the inner wall of the main body; a fixing mechanism, the fixing mechanism comprising a fixing arm and a gear, the fixing arm being located on the inner wall of the main body and at a position away from the plate roller, the gear being located on the inner wall of the fixing arm; and an ink cartridge holder. The utility model facilitates the cleaning of printing components by providing a fixing mechanism. When the printing components need to be cleaned, a controller controls the motor to start, the motor rotation drives the rotating rod rotation, the rotating rod rotation drives the two gears rotation, the gear rotation drives the fixing arm downward, and the fixing arm moves downward while losing its grip on the ink cartridge holder. When the fixing arm fully enters the interior of the main body, the ink cartridge holder can be removed for cleaning, thereby facilitating the cleaning of the printing components.

[0004] Although this device can quickly remove the ink scraper, the worker needs to pull the two moving rods with both hands to cancel the blocking of the scraper holder. Since the position of the moving rods cannot be limited, the worker can only keep pulling the moving rods if he wants to remove the scraper holder, and the scraper holder needs another worker to remove it. It takes two workers to remove the scraper holder, which increases labor costs and is not very practical. Utility Model Content

There is a guide rod 406, both ends of the guide rod 406 are fixed on the inner wall of the driving groove 402, a positioning column 407 is provided at the end of the rack plate 404, and a through groove is provided on the inner wall of the slide rail 401 corresponding to the position of the positioning column 407, and the through groove extends to the inside of the driving groove 402, the positioning column 407 is slidably set in the through groove on the inner wall of the slide rail 401, a positioning hole is provided on the surface of the limit column 301, and the positioning column 407 is inserted into the positioning hole, and a driving frame 408 is provided on the upper surface of both sides of the ink cartridge holder 200, and two driving gears 409 are installed on both sides of the driving frame 408, and the two driving gears 409 are meshed and connected, and the lower ends of the two driving gears 409 are respectively connected to the upper ends of the two driven gears 403, and the upper end of one of the driving gears 409 A connecting column 410 is provided in the center, and the cross section of the connecting column 410 is square. A driving cylinder 411 is provided on the surface of the connecting column 410, and the cross section of the inner wall of the driving cylinder 411 is adapted to the cross section of the connecting column 410. A handle 412 is provided on the upper end of the driving cylinder 411, and a spline block 414 is provided on the lower surface of the driving cylinder 411. A through hole is provided in the center of the spline block 414 and corresponds to the position of the connecting column 410. The connecting column 410 passes through the through hole provided in the center of the spline block 414. A spline ring 413 is fixed on the upper surface of the driving frame 408, and the spline ring 413 is sleeved on the surface of the spline block 414. When the staff needs to install the scraper seat body 300, they pull the two handles 412 upwards so that the handles 412 drive the driving cylinder 411 and the spline block 414 to move The spline block 414 moves upward, thereby disengaging the spline block 414 from the limit of the spline ring 413, and then the handle 412 is rotated. Since the cross section of the connecting column 410 is square, and the cross section of the inner wall of the driving cylinder 411 is adapted to the cross section of the connecting column 410, when the handle 412 drives the driving cylinder 411 to rotate, the driving cylinder 411 drives the connecting column 410 to rotate synchronously, and at the same time, the spline block 414 rotates synchronously with the driving cylinder 411. When the connecting column 410 rotates, it drives the driving gear 409 to rotate. Since the two driving gears 409 are meshed and connected, when the connecting column 410 rotates, it drives the two driving gears 409 to rotate, and the two driving gears 409 drive the two driven gears 403 to rotate. Since the two driven gears 403 are meshed and connected to the two sides of the rack plate 404,The guide rings 405 on the upper and lower sides of the rack plate 404 slide along the length direction of the guide rod 406. Therefore, when the two driven gears 403 rotate, the rack plate 404 is driven to move along the length direction of the guide rod 406, so that the rack plate 404 moves in the direction away from the slide rail 401. The rack plate 404 drives the positioning column 407 to move synchronously, so that the positioning column 407 passes through the through groove on the inner wall of the slide rail 401 and enters the driving groove 402. Then, the handle 412 is pressed downward, so that the handle 412 and the spline block 414 fall downward synchronously, so that the spline block 414 re-enters the spline ring 413 for limiting. Then, the limiting columns 301 on both sides of the scraper seat body 300 can be slid downward along the slide rail 401. When the limiting post 301 slides to the bottom of the slide rail 401, the positioning post 407 corresponds to the positioning hole of the limiting post 301. Then, the handle 412 is pulled upward to disengage the spline block 414 from the limit, and the handle 412 is rotated in the opposite direction to insert the positioning post 407 into the positioning hole, thereby completing the installation. Finally, the handle 412 is pressed downward to allow the spline block 414 to enter the spline ring 413 for limiting, thereby completing the installation. By limiting the positioning post 407, the work of disassembling and assembling the scraper seat body 300 can be completed by only one staff member, and the disassembly and assembly process only needs to pull and rotate the handle 412, which makes the disassembly and assembly process simpler, improves work efficiency, reduces labor costs, and is more practical.

[0024] According to another embodiment of the present invention, Figure 1 As shown, the surface of the handle 412 is provided with an anti-skid thread to prevent the hands from slipping; the surface of the positioning column 407 is provided with a rubber pad, which can improve the plug-in sealing performance of the positioning column 407 and the positioning hole, and improve the stability of the scraper seat body 300; the inner wall of the printing machine body 100 is installed with a plate roller 101, and fixed columns 500 are provided on both sides of the upper surface of the printing machine body 100. A top plate 501 is provided on the upper end of the fixed column 500, and a dust removal plate 503 is installed on the lower surface of the top plate 501. A sponge pad is provided on the surface of the dust removal plate 503.

When it is necessary to remove dust from the plate rollers 101 of different specifications and sizes, the telescopic push rod 502 is started so that the output end of the telescopic push rod 502 drives the dust removal plate 503 to descend, so that the dust removal plate 503 can remove dust from the plate rollers 101 of different sizes, thereby improving the applicability of the device; the cross-section of the dust removal plate 503 is arc-shaped, and the arc-shaped dust removal plate 503 can increase the contact area with the plate roller 101, thereby further improving the dust removal effect.

[0025] The use of this utility model:

[0026] When the staff needs to install the scraper seat body 300, they pull the two handles 412 upwards, so that the handles 412 drive the driving cylinder 411 and the spline block 414 to move upwards, so that the spline block 414 is released from the limit of the spline ring 413, and then rotate the handle 412. Since the cross section of the connecting column 410 is square and the cross section of the inner wall of the driving cylinder 411 matches the cross section of the connecting column 410, when the handle 412 drives the driving cylinder 411 to rotate, the driving cylinder 411 drives the connecting column 410 to rotate synchronously, and at the same time, the spline block 414 rotates synchronously with the driving cylinder 411, and the connecting column 410 is connected. When the connecting column 410 rotates, it drives the driving gear 409 to rotate. Since the two driving gears 409 are meshed and connected, the connecting column 410 drives the two driving gears 409 to rotate. The two driving gears 409 drive the two driven gears 403 to rotate. Since the two driven gears 403 are meshed and connected with both sides of the rack plate 404, and the guide rings 405 on the upper and lower sides of the rack plate 404 slide along the length direction of the guide rod 406, when the two driven gears 403 rotate, they drive the rack plate 404 to move along the length direction of the guide rod 406, so that the rack plate 404 moves away from the rack plate 404. The slide rail 401 moves in the direction of the rack plate 404, and the positioning column 407 moves synchronously, so that the positioning column 407 passes through the through groove on the inner wall of the slide rail 401 and enters the driving groove 402. Then, the handle 412 is pressed downward, so that the handle 412 and the spline block 414 fall downward synchronously, so that the spline block 414 re-enters the spline ring 413 for limiting. Then, the limiting columns 301 on both sides of the scraper seat body 300 can be slid downward along the slide rail 401. When the limiting columns 301 slide to the bottom of the slide rail 401, the positioning columns 407 correspond to the positioning of the limiting columns 301. The hole is then pulled upwards to disengage the spline block 414 from the limit, and the handle 412 is rotated in the opposite direction to insert the positioning column 407 into the positioning hole, thereby completing the installation, and finally pressing the handle 412 downwards to allow the spline block 414 to enter the spline ring 413 for limiting, thereby completing the installation. By limiting the positioning column 407, the work of disassembling and assembling the scraper seat body 300 can be completed by only one staff member, and the disassembly and assembly process only requires pulling and rotating the handle 412, which makes the disassembly and assembly process simpler, improves work efficiency, reduces labor costs, and is more practical.

[0027] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
