Description

Technical Field

[0001] The utility model relates to the technical field of printing roller adjustment, in particular to a printing roller adjustment device for printing equipment. Background Art

[0002] A printing press is a machine used to print text and images. It is a common copying device in life. Since the printing press needs to print different graphics on printed materials, and the printing roller is not easy to replace, which increases the difficulty of replacing the printing roller, a printing roller adjustment device for printing equipment is needed.

[0003] According to the description of a printing roller adjustment device for printing equipment disclosed on the patent website (authorization announcement number: CN219055696 U), "The utility model provides a printing roller adjustment device for printing equipment, which relates to the technical field of adjustment devices, including a first ring plate, two conveying components are arranged inside and near the bottom of the first ring plate, and a fixed plate is fixed on the bottom inner wall of the first ring plate and located between the two conveying components, and a groove is opened on the top of the fixed plate, and the first printing roller is rotated on the internal bearing of the groove, and a first motor is embedded and fixed on one side wall of the groove, and the output end of the first motor is fixedly connected to one end of the first printing roller. In the utility model, the screw is driven to rotate by a third motor, and the rotation of the screw drives the second U-shaped plate to move, and the movement of the second U-shaped plate drives the second printing roller therein to move, which can achieve the effect of causing the three second printing rollers with different patterns to be respectively displaced to the top of the first printing roller, thereby facilitating the replacement of the printing roller and thereby improving the printing efficiency."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the third motor drives the screw to rotate, the rotation of the screw drives the second U-shaped plate to move, and the movement of the second U-shaped plate drives the second printing roller therein to move, so that the three second printing rollers with different patterns are respectively displaced to above the first printing roller, and the cylinder drives the second ring plate to rise and fall, so as to adjust the height of the second printing roller. However, in actual use, when one of the three second printing rollers with different patterns is displaced to above the first printing roller for printing, the heights of the other two printing rollers are consistent with the heights of the printing rollers in use. When the board to be printed is printed between the first printing roller and the second printing roller, the patterns on the other two printing rollers may be printed on the board, resulting in printing disorder and poor printing effect. Therefore, it is necessary to improve a printing roller adjustment device for printing equipment to solve the above problems. Utility Model Content
