Description

Technical Field

[0001] This utility model relates to the field of printing silicone roller technology, specifically to an EVA film printing silicone roller assembly with automatic cleaning function. Background Technology

[0002] Printing silicone rollers are elastic rollers made of high-purity addition-curing liquid silicone rubber as the base material, which are formed by molding or overmolding. They have the characteristics of temperature resistance, ink resistance, aging resistance and low compression set. The surface hardness can be precisely controlled between A15 and 80. Mirror, matte or micro-textured structures can be obtained through sandblasting, grinding or plasma treatment to meet the different needs of offset printing, flexographic printing, gravure printing and digital printing for ink transfer, ink distribution and ink application.

[0003] However, existing equipment generally lacks an online cleaning mechanism that is synchronized with the printing process. Whenever impurities accumulate, manual cleaning can only be carried out by stopping the machine and using a simple scraper. This not only interrupts the continuous production cycle and directly reduces the overall output, but also easily leaves scratches or dents on the soft silicone layer surface due to uneven manual force. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an EVA film printing silicone roller assembly with automatic cleaning function, including a mounting platform, a steel roller rotatably connected to the inner wall of the mounting platform, liquid silicone fixedly connected to the surface of the steel roller, a cleaning component installed inside the mounting platform, and a limit component installed inside the mounting platform.

[0005] The cleaning assembly includes a mounting plate, a servo motor mounted on the top of the mounting plate, a lead screw fixedly connected to the output end of the servo motor, a moving platform threadedly connected to the surface of the lead screw, a top plate fixedly connected to the top of the moving platform, a slot formed at the front end of the top plate, a slidable plate slidably connected inside the slot, a scraper fixedly connected to the front end of the slidable plate, a straight groove formed at the top of the slidable plate, and a threaded groove formed at the top of the moving platform, with a bolt threadedly connected inside the threaded groove.

[0006] By using the above technical solution, the printing body and the cleaning body are integrated into the same frame by setting up an installation platform, steel roller, liquid silicone, cleaning components and limiting components. The steel roller and liquid silicone rotate continuously during printing. The servo motor in the cleaning component drives the scraper to move back and forth along the roller surface via a lead screw. The limiting components constrain the movement trajectory throughout the process, thereby achieving the effect of cleaning while printing.

[0007] As a further improvement to the above solution, the steel roller is concentric with the liquid silicone.

[0008] By using the above technical solution, and by setting the steel roller and liquid silicone to a concentric structure, the linear velocity of the liquid silicone surface is kept consistent during rotation, thus achieving the beneficial effects of uniform printing thickness, constant scraper force, and consistent cleaning effect.

[0009] As a further improvement to the above solution, the card plate passes through the card slot, the bottom of the card plate contacts the top of the moving stage, and the end of the scraper away from the card plate is close to the surface of the liquid silicone.

[0010] By using the above technical solution, and by making the card plate pass through the card slot and the end of the scraper close to the surface of the liquid silicone, a continuous contact line is formed in the length direction of the scraper, which achieves the beneficial effect of completely removing impurities at once and avoiding omissions.

[0011] As a further improvement to the above solution, two straight slots are provided, and the two straight slots are symmetrically and evenly distributed around the top center of the card plate. The bolts pass through the card plate and are threaded into the inside of the threaded slots.

[0012] Through the above technical solution, the front and rear positions of the card plate in the card slot can be steplessly adjusted and locked by two symmetrical straight grooves and bolts, which achieves the beneficial effect of precise adjustment of the distance between the scraper and the liquid silicone and adapting to different working conditions.

[0013] As a further improvement to the above solution, the limiting component includes a slider, the surface of which is slidably connected to a slide rail, and the end of the slide rail away from the slider is fixedly connected to a fixing plate.

[0014] By using the above technical solution, the lateral movement of the moving platform is restricted to a fixed trajectory through the sliding cooperation between the slider and the slide rail, thus achieving smooth movement and reduced wear.

[0015] As a further improvement to the above solution, the left and right ends of the fixing plate are fixedly connected to the inner wall of the mounting platform.

[0016] As a further improvement to the above solution, a pulley is fixedly connected to one end of the steel roller near the mounting plate.

[0017] The above technical solution allows power to be directly transmitted to the steel roller and liquid silicone by setting a pulley at the end of the steel roller and connecting it to an external drive source.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention features a cleaning assembly consisting of a servo motor, a lead screw, a moving stage, a top plate, a clamping plate, and a scraper. While the steel roller and liquid silicone are continuously rotating, the servo motor drives the lead screw to rotate and causes the moving stage to shift laterally, ensuring that the scraper maintains controllable contact with the surface of the liquid silicone. This allows for the immediate removal of impurities generated during the printing process, achieving continuous online cleaning and maintaining the cleanliness of the printed surface without stopping the machine.

[0020] This invention utilizes a limiting assembly consisting of a slider, a slide rail, and a fixed plate. When the moving stage reciprocates under the drive of a lead screw, the slider is guided along the slide rail, and the fixed plate secures the slide rail to the inner wall of the mounting platform, thereby constraining the position of the moving stage and the scraper throughout the entire process and preventing deviation. Through a straight groove, the clamping plate slides inside the groove, increasing or decreasing the distance between the scraper and the liquid silicone. Subsequently, a bolt is threaded into the threaded groove, allowing adjustment of the distance between the scraper and the liquid silicone. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 An EVA film printing silicone roller assembly with automatic cleaning function in this embodiment includes a mounting platform 1, a steel roller 2 rotatably connected to the inner wall of the mounting platform 1, liquid silicone 3 fixedly connected to the surface of the steel roller 2, a cleaning component 4 installed inside the mounting platform 1, and a limiting component 5 installed inside the mounting platform 1.

[0030] The cleaning component 4 includes a mounting plate 41, a servo motor 42 mounted on the top of the mounting plate 41, a lead screw 43 fixedly connected to the output end of the servo motor 42, a moving stage 44 threadedly connected to the surface of the lead screw 43, a top plate 45 fixedly connected to the top of the moving stage 44, a slot 46 opened at the front end of the top plate 45, a slidably connected plate 47 inside the slot 46, a scraper 48 fixedly connected to the front end of the plate 47, a straight groove 49 opened at the top of the plate 47, a threaded groove 410 opened at the top of the moving stage 44, and a bolt 411 threadedly connected inside the threaded groove 410.

[0031] When in use, the servo motor 42 is started, and the output end of the servo motor 42 drives the lead screw 43 to rotate. The rotation of the lead screw 43 drives the moving table 44 to move left and right on the surface of the lead screw 43. The synchronous scraper 48 approaches the surface of the liquid silicone 3. When some impurities are generated on the surface of the liquid silicone 3 during the printing process, the scraping surface of the scraper 48 contacts the impurities to clean the surface of the liquid silicone 3.

[0032] The steel roller 2 and the liquid silicone 3 are concentric.

[0033] The card plate 47 passes through the card slot 46, and the bottom of the card plate 47 contacts the top of the moving stage 44. The end of the scraper 48 away from the card plate 47 is close to the surface of the liquid silicone 3.

[0034] There are two straight grooves 49, which are symmetrically and evenly distributed around the top center of the clamping plate 47. The bolt 411 passes through the clamping plate 47 and is threaded into the inside of the threaded groove 410. The bolt 411 is removed from the inside of the threaded groove 410 through the straight groove 49. Then, the clamping plate 47 is pushed so that it slides inside the clamping groove 46, thereby increasing or decreasing the distance between the scraper 48 and the liquid silicone 3. Then, the bolt 411 is threaded into the inside of the threaded groove 410 to fix the clamping plate 47.

[0035] The limiting component 5 includes a slider 51, a slide rail 52 is slidably connected to the surface of the slider 51, and a fixing plate 53 is fixedly connected to the end of the slide rail 52 away from the slider 51. The slide rail 52 is slidably connected inside the slide rail 52 through the slider 51, thereby limiting the position of the entire moving platform 44 during its movement.

[0036] The left and right ends of the fixing plate 53 are fixedly connected to the inner wall of the mounting platform 1.

[0037] A pulley 6 is fixedly connected to one end of the steel roller 2 near the mounting plate 41.

[0038] The implementation principle of an EVA film printing silicone roller assembly with automatic cleaning function in this application embodiment is as follows: when using the EVA film printing silicone roller, the entire steel roller 2 is rotated by the external drive source connected to the pulley 6, which synchronously drives the liquid silicone 3 to rotate, and the printing work is carried out.

[0039] Start the servo motor 42. The output end of the servo motor 42 drives the lead screw 43 to rotate. The rotation of the lead screw 43 drives the moving table 44 to move left and right on the surface of the lead screw 43. The synchronous scraper 48 approaches the surface of the liquid silicone 3. When some impurities are generated on the surface of the liquid silicone 3 during the printing process, the scraping surface of the scraper 48 contacts the impurities to clean the surface of the liquid silicone 3.

[0040] The bolt 411 is removed from the inside of the threaded groove 410 through the straight groove 49. Then, the clamping plate 47 is pushed to slide inside the clamping groove 46, so that the distance between the scraper 48 and the liquid silicone 3 is increased or decreased. Then, the bolt 411 is threaded into the inside of the threaded groove 410 to fix the clamping plate 47.

[0041] The slider 51 is slidably connected to the inside of the slide rail 52, which limits the position of the entire moving platform 44 during its movement.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
