Description

Anti-warping device for printing machine

Technical Field

The utility model relates to the technical field of printing equipment, in particular to an anti-warping device for a printing machine.

Background Art

A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate and mounted on a printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate.

For example, the utility model with announcement number CN216579813U discloses a device for preventing edge warping of a printer, including a nozzle, a roller, an electrostatic mechanism, a roller frame, a brush and paper, wherein the roller is movably mounted on the roller frame, the nozzle is arranged above the nozzle, the electrostatic mechanism is connected to the roller frame, the roller is provided with the brush, and the paper is closely arranged on the side wall of the roller through a bite. After the paper enters the roller, the utility model allows the target paper to carry a static charge opposite to the target roller, and the positive and negative charges attract each other, so that the paper is always closely attached to the roller, and the electrostatic adsorption effect is used to solve the problem of edge warping of digital sheetfed printing. After the roller bites the target paper through the bite, it first presses the paper with a brush, and then allows the electrostatic generator to pass through the electrostatic rod to carry a positive charge on the paper, so that the paper is closely attached to the negatively charged roller, so as to always ensure that the distance between the nozzle and the target paper is consistent, thereby preventing the nozzle from being damaged.

In the process of implementing this application, it was found that the technology has the following problems: the existing anti-warping devices for printing machines mostly use a cleaning brush to clean the dust accumulated on the surface of the paper during use to prevent the dust accumulated on the surface of the paper from affecting the normal printing of the paper, but most of the cleaning brushes are positioned and installed on the front side of the printing machine, which makes it easy for the cleaning brush to drive the thicker paper to move on the outer end of the roller body during the dust cleaning process, thereby reducing the practicality of the device.

At the same time, the collecting mechanism 6 is activated to absorb the floating dust generated during the cleaning process of the positioning mechanism 5, thereby avoiding the staff from inhaling a large amount of dust during the operation of the device, thereby improving the safety of the device during use.

As shown in Figures 1, 2 and 4, the cleaning mechanism 4 includes a U-shaped fixing plate 401, which is installed on the front side of the U-shaped support frame 2. The inner walls on the left and right sides of the U-shaped fixing plate 401 are provided with card slots, and the insides of the two groups of card slots of the U-shaped fixing plate 401 are slidably connected with sliders 404.

Specifically, when the positioning mechanism 5 cleans the paper clamped on the inner ring of the drum body 1, the fixing rod 603 and the fan 605 are driven to rotate by starting the motor 601, so that the fan 605 forms a negative pressure during the rotation to suck the dust generated by the positioning mechanism 5 in the process of cleaning the paper into the inside of the bellows 602, thereby avoiding the staff from inhaling a large amount of dust during the operation of the device, thereby improving the safety of the device during use.

As shown in Figure 3, a card slot is opened on the front side of the bellows 602, and a collection box 7 is slidably connected inside the card slot of the bellows 602, and the collection box 7 is located at the lower end of the fan 605; specifically, the collection box 7 is located at the inner bottom end of the bellows 602 and the lower surface of the L-shaped fixing plate 604, so that the collection box 7 collects the dust accumulated inside the bellows 602, thereby facilitating the staff to regularly clean the dust accumulated inside the bellows 602.

As shown in Figure 3, a groove is provided on the back side of the collecting box 7, and a magnetic block 8 is arranged inside the groove of the collecting box 7. The side of the magnetic block 8 away from the collecting box 7 is adsorbed on the inner wall of the bellows 602 close to the U-shaped fixing plate 401; specifically, by pushing the collecting box 7, the side of the magnetic block 8 away from the collecting box 7 is adsorbed on the inner wall of the bellows 602 close to the U-shaped fixing plate 401, so that the magnetic block 8 limits the moving position of the collecting box 7 inside the bellows 602, thereby avoiding the movement of the collecting box 7 during use as much as possible.

In summary: by starting the two sets of electric telescopic rods 403 to drive the two sets of sliders 404 and the connecting plate 406 to move, the side of the cleaning brush 405 inside the connecting plate 406 slot close to the U-shaped support frame 2 is abutted against the outer surface of the inner ring of the roller body 1 that is clamped with the paper, so that in the subsequent process of the roller body 1 driving the paper to rotate, the cleaning brush 405 cleans the dust accumulated on the outer surface of the paper, thereby minimizing the dust accumulated on the outer surface of the paper affecting the printing quality of the printing press; by starting the electric telescopic rod 403 to push the two sets of sliders 404 to drive the connecting plate 406 and the cleaning brush 405 to move, the position of the cleaning brush 405 at the front end of the roller body 1 can be adjusted according to the thickness of the paper, thereby minimizing the movement of the paper when the cleaning brush 405 cleans the thicker paper clamped on the inner ring of the roller body 1.

At the same time, by pushing the limit plate 502, the limit plate 502 is snapped into the through hole of the connecting plate 406, and then by pushing the limit plate 502, the lower surface of the limit plate 502 is abutted against the upper surface of the cleaning brush 405 and the connecting plate 406, so that the positioning mechanism 5 limits the moving position of the cleaning brush 405 in the card slot of the connecting plate 406, thereby minimizing the movement of the cleaning brush 405 during use; by starting the motor 601 to drive the fixing rod 603 and the fan 605 to rotate, the fan 605 forms a negative pressure during the rotation process to suck the dust generated by the positioning mechanism 5 in the process of cleaning the paper into the inside of the bellows 602, thereby minimizing the staff from inhaling a large amount of dust during the operation of the device.
