Description

Technical Field

[0001] This utility model relates to the field of printing roller processing technology, specifically to a printing roller engraving device with controllable depth. Background Technology

[0002] Printing rollers are essential tools for transferring ink during the printing process. They are typically made of metal or rigid materials and have an elastic layer covering their surface. In gravure printing, the role of the printing roller is particularly crucial. Through contact with the ink roller, it evenly transfers ink onto the substrate, thus completing the printing process.

[0003] Existing equipment for printing roller production is inconvenient for installing the printing roller workpiece and requires connecting the clamping assembly to the power assembly, making it cumbersome to use. In addition, existing devices lack the function of adjusting the grinding depth of the cutting tool, while the engraving depth of the printing roller has a significant impact on the printing effect. Therefore, we propose a printing roller engraving device with controllable depth. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a depth-controllable printing roller engraving device. This device features a reliable workpiece clamping unit for easy clamping of the printing roller workpiece, and can rotate the workpiece while it is fixed in place to support the engraving of the tool on the outer circumference of the roller. Furthermore, it has a reliable printing roller engraving unit that can control the engraving of the tool on the roller, adjust the engraving depth, and absorb debris generated during the engraving process, ensuring a clean working environment. This effectively solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a depth-controllable printing roller engraving device, comprising a base, a workpiece clamping unit, and a printing roller engraving unit;

[0006] Base: It is arranged horizontally and has a U-shaped and inverted mounting bracket fixedly connected to the upper end;

[0007] Workpiece clamping unit: includes a transverse sliding column, a top block, hydraulic rods, bearings, a drive shaft, an electric chuck, and limiting protrusions. The lower ends of both sides of the mounting frame are slidably connected to transverse sliding columns. The upper and lower sides of the transverse sliding columns are integrally fixedly connected to transverse limiting protrusions, which are also slidably connected to the mounting frame. A circular top block is fixedly connected to the outward end of the transverse sliding column. Three hydraulic rods are arranged in an array along the outer circumference of the transverse sliding column on the left and right sides of the mounting frame. The telescopic ends of the hydraulic rods face outward and are fixedly connected to the edge of the top block end face. The other end of the transverse sliding column extends into the inner side of the mounting frame, and a bearing is fixedly installed inside the inward end of the transverse sliding column. Transverse drive shafts are rotatably connected inside the bearings on both the left and right sides. Electric chucks are fixedly connected to the extended ends of the two drive shafts. The openings of the two electric chucks face each other. An electric motor is also embedded inside the transverse sliding column. The output shaft of the electric motor is fixedly connected to the inner end of the drive shaft through a coupling.

[0008] Printing roller engraving unit: installed on the lower side of the horizontal end of the mounting frame.

[0009] The base and mounting frame are the main components of the device. The mounting frame is used to install the printing roller engraving unit, which controls the cutting tool to engrave on the printing roller and can adjust the engraving depth. The hydraulic rod pushes the top block, which in turn drives the transverse slide column to move left and right. The bearing is used to install the drive shaft and protect it. The electric chuck is used to clamp and fix the shaft at the end of the printing roller. The drive shaft supports the rotation of the electric chuck. After the printing roller workpiece is installed and fixed, the motor inside the transverse slide column drives the electric chuck to rotate through the drive shaft, which in turn drives the printing roller to rotate, so as to support the cutting tool to engrave on the outer circumference of the printing roller.

[0010] Furthermore, the workpiece clamping unit also includes a hydraulic support arm and a support frame. A vertical hydraulic support arm is embedded in the middle side of the machine base, with its telescopic end extending upwards and a support frame fixedly connected to its end. The hydraulic support arm is used to drive the support frame to move up and down, and the support frame can lift the printing roller workpiece. By lifting the printing roller in the middle of the workpiece, it is convenient for the clamping components on both sides to clamp and fix the end shaft of the printing roller.

[0011] Furthermore, the printing roller engraving unit includes a hydraulic slide column, a movable mounting frame, an electric push rod, and a movable short column. A hydraulic slide column is embedded in the middle of the upper horizontal end of the mounting frame. The telescopic end of the hydraulic slide column extends downwards and has a square mounting groove on its lower side. The movable mounting frame is slidably connected inside the groove. The movable mounting frame is horizontally positioned and maintains a longitudinal slidable connection with the mounting groove. An electric push rod is embedded in the lower end of the hydraulic slide column. The electric push rod is perpendicular to the movable mounting frame, and its telescopic end is fixedly connected to the middle position of the movable mounting frame. A movable short column is slidably connected horizontally inside the movable mounting frame. The movable short column is slidably connected to the movable mounting frame via an upper electric roller. The hydraulic slide column is used to drive the lower tool assembly to rise and fall, thereby adjusting the grinding depth of the tool. The electric push rod is used to drive the tool assembly to move longitudinally on the horizontal plane. The movable short column is used for mounting the tool assembly and can drive the tool assembly to move laterally on the horizontal plane.

[0012] Furthermore, the printing roller engraving unit also includes a motor, a tool chuck, and a control panel. The lower end of the moving short column is fitted with a motor, the motor's output shaft extends downwards, and a tool chuck is fixedly connected to its end. The control panel is mounted on the right front side of the machine base. The tool chuck is used to mount grinding tools, and the motor drives the tool chuck and grinding tools to rotate, thereby performing the grinding operation. The operator inputs programming data at the control panel according to the drawings. The control panel can automatically control the tool's movement in three dimensions, thereby engraving patterns on the surface of the printing roller.

[0013] Furthermore, it also includes a chip suction tank and a negative pressure fan. The upper end of the base has a horizontally oriented chip suction tank with a semi-circular groove in its vertical cross-section. A rectangular through-hole is located at the bottom of the groove. The base has a hollow chamber inside, and a negative pressure fan is installed at the rear of the base. The suction end of the negative pressure fan is connected to the interior of the hollow chamber. The negative pressure fan generates suction at the chip suction tank to remove the waste chips generated during the engraving process. The semi-circular structure of the chip suction tank allows the waste chips to slide down the tank wall to the bottom and enter the base through the through-hole.

[0014] Furthermore, it also includes a chip collection drawer, which is slidably connected to the right side of the machine base and communicates with the discharge port of the hollow cavity inside the machine base. The chip collection drawer is used to collect the processed chips and can be pulled outwards to empty them.
