Description

Technical Field

[0001] The utility model relates to the technical field of printing rotary screen cleaning, in particular to a flushing device for processing a flexible printing rotary screen. Background Art

[0002] Flushing equipment for flexographic printing rotary screen processing is mainly used to clean and maintain the screen in the rotary screen printing machine. In the flexographic printing process, the screen is a key component for transferring ink to the printing material, and its cleanliness directly affects the printing quality. Therefore, the design and use of flushing equipment is crucial to improving printing efficiency and product quality.

[0003] In the flexographic rotary screen processing, the cleanliness of the screen has a crucial impact on the printing quality. The screen is the core component in the printing process, which is responsible for carrying the ink and transferring it to the substrate through a specific pattern. If there is ink or other contaminants left on the screen, these impurities will clog the tiny holes of the screen, resulting in the inability to accurately transfer the ink during printing, thus affecting the clarity and color reproduction of the printed product.

[0004] In order to ensure the printing quality, the screen must be cleaned regularly. However, the existing rotary screen washing equipment has poor effect in removing residual stains on the screen and has too many dead corners for cleaning. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a flushing device for processing a flexible printing rotary screen.

[0006] The technical solution of the utility model is: a flushing device for processing a flexible printing cylinder, comprising a cleaning tank, a clamping assembly arranged inside the cleaning tank for clamping the flexible printing cylinder, a water storage chamber connected to a drainage valve at the bottom of the cleaning tank, and a spray assembly arranged at the top of the cleaning tank and connected to the water storage chamber; a drainage valve is also arranged at the bottom of the cleaning tank; a filter plate is arranged at the drainage valve;

[0007] The cleaning tank is also provided with a water inlet valve and an ultrasonic transducer; an ultrasonic generator is provided outside the cleaning tank; the ultrasonic transducer is electrically connected to the ultrasonic generator;

[0008] A waterproof cover is provided outside the cleaning tank, and the waterproof cover wraps the outside of the cleaning tank to prevent the spray assembly from splashing water;

[0009] The clamping assembly comprises a rotating motor arranged on the inner side wall of the cleaning tank, and a clamping piece arranged on the rotating motor; the clamping pieces are two, the two clamping pieces are arranged crosswise, and a spline and an elastic member for sliding and telescopic movement are arranged in the middle of the clamping pieces;

[0010] A water pump is arranged inside the water storage cavity; the spray assembly comprises a support plate arranged on the top of the cleaning tank, and a plurality of fine-pore spray heads arranged at intervals on the support plate and connected to the water storage cavity.

[0011] Description: The round net is fixed by retractable clips and elastic parts, which are cross-arranged and fixed from four directions to prevent the round net from slipping. It can be reused after wastewater treatment and repeatedly cleaned many times, which can greatly save water resources. Finally, clean water is passed in for flushing to ensure the cleaning effect.

[0012] Furthermore, a trough body is provided at the bottom of the support plate, an electric-controlled slide rail is provided inside the trough body; and a cleaning component is provided on the electric-controlled slide rail.

[0013] Description: The cleaning component can slide along the length direction of the support plate through the electrically controlled slide rail, and the cleaning component can be controlled to slide back and forth to achieve the overall sliding cleaning of the round screen.

[0014] Further, the cleaning assembly includes a hydraulic rod arranged on the electric control slide rail, a mounting block arranged at the output end of the hydraulic rod, and a cleaning plate group slidably arranged at the bottom of the mounting block;

[0015] The cleaning plate group is composed of two submodules that move toward or away from each other, and the two submodules are driven by an electric push rod;

[0016] The submodule includes a plate body slidably arranged at the bottom of the mounting block, a cleaning liquid bag arranged on the outer wall of the plate body, and a rolling member movably arranged on the inner wall of the plate body; a groove is arranged at the bottom of the mounting block, and a protrusion is arranged on the plate body to be slidably engaged with the groove; a cavity is arranged inside the plate body, and the cleaning liquid bag is connected with the cavity inside the plate body; a mounting groove connected with the cavity is arranged on the inner side wall of the plate body; the longitudinal section of the inner side wall of the plate body is an arc structure; the cleaning liquid bag is filled with cleaning liquid.

[0017] Description: The height of the cleaning component is adjusted by a hydraulic rod to keep it consistent with the height of the round screen. The electric push rod is used to control the distance between the two submodules so that they can fit closely with the surface of the round screen. The rolling part rotates to discharge the cleaning liquid bag, and the cleaning liquid is applied to the surface of the round screen to enhance the cleaning effect. At the same time, it is avoided that the cleaning liquid is directly added to the cleaning tank so that the cleaning liquid is diluted by water, thereby reducing the cleaning effect of the cleaning liquid. Releasing the cleaning liquid on the surface of the round screen can ensure that the high-concentration cleaning liquid can effectively clean the stains on the surface of the round screen. While applying the cleaning liquid, the friction of the plate body on the surface of the round screen can further enhance the cleaning effect. Compared with adding the cleaning liquid directly to the cleaning tank, applying the cleaning liquid on the surface of the round screen can not only save the amount of cleaning liquid, but also achieve better cleaning effect.

[0018] Further, the rolling element includes a flexible ball bearing that is slidably engaged and arranged inside the mounting groove, and a return spring with one end arranged inside the mounting groove and the other end fixedly connected to the flexible ball bearing;

[0019] The inner wall of the plate body and the surface of the flexible ball are both provided with brushes; the flexible ball is in sealing contact with the opening of the installation groove under the elastic force of the return spring in the natural state.

[0020] Description: The round screen is squeezed and slid by the flexible ball, and the opening of the installation slot is sealed by the reset spring. When the flexible ball contacts the round screen, the flexible ball squeezes the reset spring, and a gap appears at the opening of the installation slot, so that the cavity connecting the installation slot and the cleaning liquid bag is opened, and the cleaning liquid flows out and adheres to the surface of the round screen through the flexible ball. The surface of the round screen is further cleaned by friction with a brush.

[0021] Further, the rolling element includes a roller arranged inside the mounting groove through a shaft, and a torque sensor arranged on the shaft;

[0022] The roller surface is provided with a liquid carrying tank; the communication point between the cleaning liquid bag and the internal cavity of the plate body is provided with an electronic valve; the inner side wall of the plate body and the roller surface are both provided with a rubber brush head.

[0023] Description: When the cleaning component slides under the control of the electric control slide rail, the roller contacts the surface of the round screen and generates relative motion to rotate. The rotation state of the roller is detected by the torque sensor. When the threshold is exceeded, the electronic valve is opened to allow the cleaning liquid to flow out, coating the surface of the round screen and cleaning it through friction with the rubber brush head.

[0024] The beneficial effects of the utility model are:

[0025] The utility model fixes the printing round screen in the cleaning tank by means of a clamping component, fixes the round screen by means of a retractable clip and an elastic member, fixes the round screen in four directions to prevent the round screen from slipping, rotates the printing round screen in water by means of a rotating motor to enhance the cleaning effect, stores the cleaned water through a water storage chamber after being adsorbed and filtered by a filter plate, sprays the round screen from a spray component, rinses the surface of the round screen by means of a fine-pore nozzle, and enhances the cleaning efficiency; water is injected into the cleaning tank, and ultrasonic cleaning is performed on the round screen by means of an ultrasonic generator and an ultrasonic transducer, and a cleaning dead angle is avoided.

[0048] The printing round screen is fixed inside the cleaning tank 1 by the clamping assembly 2, and the round screen is fixed by the retractable clip 22 and the elastic member, and fixed from four directions to prevent the round screen from slipping. The printing round screen is rotated in the water by the rotating motor 1 to enhance the cleaning effect. The cleaned water is adsorbed and filtered by the filter plate through the water storage chamber 3 and then stored. The round screen is sprayed from the spray assembly 4, and the surface of the round screen is rinsed by the fine-pore nozzle 42 to enhance the cleaning efficiency.
