Description

Technical Field

[0001] This utility model relates to the field of printing cleaning equipment technology, and in particular to a cleaning mechanism for printing tables. Background Technology

[0002] In the continuous printing process on the printing production line, various impurities, such as ink and dust, will adhere to the printing table. These impurities will affect the printing quality. During the printing process, the printing table surface is prone to the accumulation of ink, dust, and other impurities. If not cleaned in time, it will seriously affect the printing quality. Although existing cleaning mechanisms for printing tables can achieve basic cleaning functions, the cleaning methods are limited and cannot adapt to different types of impurities, such as the cleaning needs of stubborn ink and light dust. The supply of cleaning fluid cannot be precisely controlled, which can easily lead to excessive waste or insufficient supply, resulting in poor cleaning effect. The reciprocating motion amplitude and frequency of the wiping components are fixed, and the wiping head is inconvenient to replace. Based on the prior structure of the original patent application No. 2024211488802, a wiping device for a printing apparatus, our company further improves the cleaning mechanism to enhance cleaning efficiency and the intelligence of cleaning.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] As shown in Figures 1-4, the present invention provides a cleaning mechanism for a printing table, which is installed on the printing machine table. The horizontal plate 401 of the mounting component is connected to the moving mechanism on the upper part of the printing table 1 and is driven to move by it. That is, it is connected to the moving rod 304 of the lifting mechanism 3 with lifting function. The folding frame 402 is fixed to the lower end of the horizontal plate 401.

[0020] The original structure of the upper part of the printing table is as follows: the moving mechanism 3, as shown in the figure, includes a frame 301, and the two ends of the inner side of the frame 301 are connected to the second threaded rod 302. The upper end of the second threaded rod 302 is connected to the second motor 303, and the outer end of the second threaded rod 302 is connected to the moving rod 304. A slot is opened on one side of the moving rod 304, and a third threaded rod 305 is connected inside the slot. One end of the third threaded rod 305 is connected to the third motor 306. The outer end of the third threaded rod 305 is in contact with the cleaning mechanism 4. Rotating the second threaded rod 302 drives the moving rod 304 to move up and down, and rotating the third threaded rod 305 drives the cleaning mechanism to move along the third threaded rod 305.

[0021] One end of the water pipe 405 is connected to the square pipe 403, and the other end is connected to the water pump (not shown in the figure) after being connected in series with a flow meter and a solenoid valve. The lower end of the square box 409 is also provided with a groove (not shown in the figure). The upper end of the replaceable wiping head 410 is provided with an adapter protrusion, and there are locking positions on both sides of the protrusion. The protrusion is a kind of elastic claw. The elastic claw is embedded in the groove to fix it to the lower end of the square box 409. Pressing the elastic claw can make the claw disengage from the slot, which is convenient for replacing the wiping head. The replaceable wiping head 410 is of three types: a brush head for dust cleaning, a sponge head for light ink, and a fiber cloth head for stubborn ink.

[0022] Hot air duct 419 is located on one side of horizontal plate 401. Hot air duct 419 has several air outlets, and the air outlets face the printing table. Hot water generated by the hot air generator is output through the hot air duct. The hot air generator and hot air duct 419 are applications of existing equipment. Their model details and working principle will not be detailed here.

[0023] The cleanliness sensor 421 is vertically mounted at the lower end of the folding frame 402, with the detection probe facing the printing table surface. It is used to collect impurity data in real time and is a conventional camera detector. The controller 422 is connected to the cleanliness sensor 421, hot air generator, flow meter, solenoid valve, water pump and motor respectively by wiring. The controller surface is equipped with a display screen and control buttons.

[0024] When the cleaning fluid supply component is working, the controller determines the impurity status based on the image data detected by the cleanliness sensor 421, controls the water pump 406 to start, and the cleaning fluid in the water tank 407 is finally delivered to the dripper 404 through the water pipe 405 and evenly dripped onto the printing table. The flow meter monitors the flow rate in real time, and the solenoid valve adjusts the opening to control the supply.

[0025] During use, the wiping assembly can be replaced with a different wiping head 410 at any time depending on the type of impurity. For example, a fiber cloth head can be used for stubborn ink, and a brush head can be used for dust. The head is fixed to the lower end of the box 409 by a snap-fit ​​structure 415.

[0026] After cleaning is complete, the controller activates the hot air generator, and hot air is blown onto the printing table through hot air pipe 419 to quickly dry any remaining liquid. Alternatively, hot air can be blown while cleaning is being performed, making it very practical.

[0027] The above structure and principle can be fully realized: by combining a flow meter, solenoid valve, and cleanliness sensor, the controller adjusts the supply of cleaning fluid to avoid waste and ensure cleaning effect. The reciprocating frequency of the wiping head can be changed by controlling the motor speed to adapt to different cleaning needs. After cleaning, the printing table is dried with hot air to prevent the liquid from affecting subsequent printing. The replaceable wiping head can be adapted to different types of cleaning, improving the cleaning targeting. The replaceable wiping head is connected by a snap-fit ​​structure, making replacement convenient. The overall cleaning effect is good, practical, and can achieve intelligent control.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
