Description

Technical Field

[0001] This utility model relates to the field of longan drying oven technology, and in particular to a screen roller cleaning system for medical packaging printing. Background Technology

[0002] The anilox roller used in medical packaging printing, as a core component of the printing press's ink supply system, has a large number of uniformly shaped micro-holes, known as "inking holes," evenly distributed on its surface. These micro-holes are responsible for delivering a fixed amount of ink to the printing plate, which has a crucial impact on the printing effect. During the printing process, the ink is prone to solidification, which can clog these micro-holes and affect the ink delivery. Therefore, to ensure printing quality, the anilox roller needs to be cleaned regularly. Currently, common cleaning methods include manual cleaning, strong corrosive chemical cleaning, spray cleaning, and ultrasonic cleaning.

[0003] Manual cleaning is convenient and does not cause pollution; however, incomplete cleaning can negatively impact ink transfer. This method is typically suitable for anilox rollers with low screen rulings or lightly contaminated rollers. Strongly corrosive chemical cleaning offers good cleaning results but can corrode the anilox roller and cause environmental pollution. Spray cleaning does not damage the surface of the anilox roller or the ink cavity walls. Ultrasonic cleaning is slow and time-consuming when cleaning large ink solids. Furthermore, the anilox roller needs to be immersed in the cleaning solution for an extended period and subjected to cavitation bubbles, which can cause micro-cracks on the surface. As these cracks accumulate, the cleaning solution can penetrate the anilox roller substrate, corroding it and affecting its lifespan.

[0004] In existing technologies, ordinary ultrasonic cleaning devices take too long to clean, have low cleaning efficiency, and chemical cleaning can easily damage the surface of the anilox roller, affecting its service life. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning system for anilox rollers used in medical packaging printing. This device combines mechanical friction and the cavitation effect of ultrasonic cleaning fluid to clean the anilox rollers, which can not only shorten the ultrasonic cleaning time, but also make the removal of ink solids on the surface of the anilox rollers more thorough.

[0006] To achieve the above objectives, a screen roller cleaning system for medical packaging printing is provided, comprising a cleaning tank and a cleaning platform. The upper and lower parts of the interior of the cleaning tank are fixedly connected to a support column. A rotary motor is fixedly connected to one inward end of the support column. The output end of the rotary motor is fixedly connected to a first cleaning roller via a coupling.

[0007] The cleaning tank has an internal slot, and an ultrasonic transducer layer is laid on the outer surface of the internal slot. An ultrasonic slot is formed on the outer surface of the ultrasonic transducer layer. A cleaning base is fixedly connected to the middle of the cleaning platform. A motor is installed on the inner side of the middle of the cleaning base, and the output end of the motor is fixedly connected to a second cleaning roller through a coupling.

[0008] An external rotating ring is connected to the outer center of the cleaning base via a rotating shaft, and a limit slot is provided inside the external rotating ring.

[0009] A vibrating base is fixedly connected to the bottom of the cleaning base, and a drainage hole is provided on the outer surface of the cleaning platform.

[0010] A fixed base is fixedly connected to the bottom of the cleaning platform, and a high-pressure spray cover is installed on the top of the cleaning tank.

[0011] A booster pump is fixedly connected to the top of the high-pressure spray cover, and a water supply pipe is fixedly connected to the connecting pipe of the booster pump.

[0012] A ring-shaped water pipe is fixedly connected to the lower end of the booster pump, and a nozzle is fixedly connected to the bottom of the ring-shaped water pipe.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. This device uses multiple cleaning rollers to clean the inside and outside of the anilox roller, which effectively improves the comprehensiveness and thoroughness of cleaning, reduces ink residue, and also increases the cleaning speed.

[0015] 2. By combining mechanical friction with ultrasonic cavitation, the cleaning efficiency is significantly improved, the cleaning time is shortened, and the risk of corrosion of the anilox roller by chemical cleaning solution is reduced, thus extending its service life.

The upper and lower parts of the cleaning tank 1 are fixedly connected to a support column 102. A rotary motor 105 is fixedly connected to one inward end of the support column 102. The output end of the rotary motor 105 is fixedly connected to a first cleaning roller 106 through a coupling. The support column 102 is symmetrically fixed at the top and bottom of the tank. Its inward extension end is connected to the rotary motor 105 through a flange. The output shaft of the motor drives the first cleaning roller 106 to rotate through the coupling.

[0023] The cleaning tank 1 has an internal slot 103 inside, and an ultrasonic transducer layer 101 is laid on the outer surface of the internal slot 103. An ultrasonic slot 104 is formed on the outer surface of the ultrasonic transducer layer 101. A cleaning base 201 is fixedly connected to the middle of the cleaning platform 2. A motor is set on the inner side of the middle of the cleaning base 201, and the output end of the motor is fixedly connected to the second cleaning roller 204 through a coupling. The internal slot 103 inside the tank provides installation space for the ultrasonic transducer layer 101. The ultrasonic slots 104 designed on the outer surface of the transducer layer are distributed in a matrix to ensure that the cavitation effect evenly covers the surface of the roller. The motor built into the cleaning base 201 drives the second cleaning roller 204 through a reducer. The roller surface is covered with a corrosion-resistant soft brush.

[0024] An external rotating ring 202 is connected to the outer center of the cleaning base 201 via a rotating shaft. The external rotating ring 202 has a limiting groove 203 inside. The external rotating ring 202 is connected to the cleaning base 201 via the rotating shaft. Its internal limiting groove 203 adopts an elastic buckle design, which can be used to fix the top of the screen rollers with different diameters.

[0025] A vibrating base 206 is fixedly connected to the bottom of the cleaning base 201. A drain hole 205 is provided on the outer surface of the cleaning platform 2. The vibrating base 206 has a built-in eccentric wheel mechanism that can generate high-frequency micro-vibration, which is transmitted to the bottom of the screen roller through the cleaning platform 2 to accelerate the stripping of the sludge. The drain hole 205 is distributed in a ring on the edge of the cleaning platform and is connected to the waste liquid recycling pipe.

[0026] A fixed base 3 is fixedly connected to the bottom of the cleaning platform 2, and a high-pressure spray cover 4 is installed on the top of the cleaning tank 1. The fixed base 3 can provide stable support for the device and ensure that the cleaning process is smooth and efficient.

[0027] A booster pump 401 is fixedly connected to the top of the high-pressure spray cover plate 4. A water supply pipe 402 is fixedly connected to the connecting pipe of the booster pump 401. The booster pump 401 can provide high-pressure water flow, which is delivered to the annular water pipe 403 through the water supply pipe 402.

[0028] A ring-shaped water pipe 403 is fixedly connected to the lower end of the booster pump 401. A nozzle 404 is fixedly connected to the bottom of the ring-shaped water pipe 403. The nozzle 404 can spray high-pressure water evenly to cover the surface of the screen roller. Combined with the ultrasonic cavitation effect, it can achieve a high-efficiency cleaning effect, ensure that the dirt on the surface of the screen roller is completely removed, and improve the operating efficiency of the equipment.

[0029] Working principle: First, the medical printing anilox roller to be cleaned is vertically installed on the cleaning platform 2. Its bottom is positioned and supported by the second cleaning roller 204 of the cleaning base 201, and its top is fixed by the limiting groove 203 of the external rotating ring 202. After the cleaning fluid is injected into the cleaning tank 1, the system is started. The ultrasonic transducer layer 101 generates cavitation through the ultrasonic grooving 104, decomposing the ink on the surface of the anilox roller and in the micropores. At the same time, the rotary motor 105 located above and below the tank drives the first cleaning roller 106 to rotate, and the motor in the cleaning base 201 drives the second cleaning roller 106 to rotate. The cleaning roller 204 rotates, removing the ink solids from the surface of the anilox roller through mechanical friction. After the main cleaning is completed under the combined action of ultrasonic cavitation and mechanical friction, the booster pump 401 is started, pressurizing the cleaning fluid and delivering it to the annular water pipe 403 through the water pipe 402. The nozzle 404 sprays high-pressure water downwards to rinse the anilox roller and remove residual dirt. During the cleaning process, the vibrating base 206 generates high-frequency micro-vibrations to promote the peeling of dirt. The waste liquid is discharged through the drain hole 205 on the outer surface of the cleaning platform 2. After the cleaning is completed, the system is turned off and the anilox roller is removed.
