Description

Technical Field

[0001] This utility model relates to the field of printing trademarks on the front panel of refrigerator drawers, specifically to an automatic pad printing device for the front panel of drawers. Background Technology

[0002] Pad printing technology has become a major method for printing and decorating various object surfaces due to its simple process. The workflow is as follows: First, the pattern to be printed is engraved on a steel plate. Then, an ink cup is placed on the steel plate, and the ink cup moves on the steel plate to leave ink in the pattern. The pad printing head moves to the steel plate to pick up the ink onto its surface. Then, the pad printing head moves to the surface of the workpiece to be printed, and pressing down will print the pattern.

[0003] The existing technology has the following problems: Traditional pad printing machines have an ink cup and a corresponding pad printing head, which means that only one pattern and color can be printed at a time. Moreover, the printing effect is not good on the front panel of a refrigerator drawer with a curved surface. In addition, after the pad printing head of the existing pad printing machine has printed the material, ink residue still remains on the pad, which will affect the accuracy of subsequent pad printing. Utility Model Content

[0013] Preferably, the pad printing head moving assembly is positioned above the ink table, the cleaning table, and the workpiece placement assembly. The slider moves back and forth on the slide rail, driving the pad printing head to move back and forth. The pad printing head can pick up ink on the steel plate, print the ink on the front panel of the drawer on the workpiece placement table, and remove residual ink from the cleaning tape.

[0014] Preferably, a drive motor is connected to the drive roller, which drives the drive roller to rotate, thereby moving the cleaning belt.

[0015] The beneficial effects of this utility model are:

[0016] The automatic pad printing device for drawer front panels provided by this invention, by setting up three moving ink heads, three ink cups, and a steel plate, enables the pad printing of multiple drawer front panels in one operation, improving pad printing efficiency. A cleaning tape is installed between the ink table and the workpiece placement assembly. After each printing of a drawer front panel, the moving ink heads remove residual ink from the cleaning tape before the next ink application, ensuring no ink residue remains on the moving ink heads and guaranteeing the quality of each pad printing. The workpiece placement stage is controlled by a servo motor to rotate back and forth on the mounting base, thereby adjusting the angle of the drawer front panels on the workpiece placement stage. For workpieces with curved drawer front panels, fine-tuning the angle allows for high-quality pad printing of curved workpieces. Attached Figure Description

[0018] Figure 2 This is a perspective view of an automatic pad printing device for the front panel of a drawer. Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings:

[0020] Combination Figure 1 and Figure 2 An automatic pad printing device for drawer front panels includes a machine platform 1, a support frame 2 at the rear of the machine platform, an ink moving component at the bottom of the support frame 2, and a pad moving component at the top of the support frame. The ink moving component drives the ink cup to move back and forth on the steel plate, and the pad moving component drives the moving pad to move.

[0021] An ink station 3 is located in the middle of the machine platform, a workpiece placement assembly is located at the front of the machine platform, and a cleaning station 4 is located between the ink station and the workpiece placement assembly.

[0022] The ink station 3 has three steel plates 5, each with an ink cup 6. The steel plates 5 are printed with patterns. The ink cups 6 can move back and forth on the steel plates 5 to leave ink in the patterns on the steel plates. The ink cups and steel plates are existing technologies.

[0023] The ink moving assembly includes a moving cylinder 7 and a fixed base plate 8 fixed to the bottom of the support frame. The moving cylinder 7 is fixed on the fixed base plate 8, and two guide rods 9 are slidably connected on the fixed base plate 8. The front end of the telescopic rod of the moving cylinder 7 is fixedly connected to a fixed horizontal plate 10, and the front end of the guide rod 9 is also fixedly connected to the fixed horizontal plate 10.

[0024] Three oil cup holders 11 are fixedly connected to the front end of the fixed horizontal plate 10. The oil cups 6 correspond one-to-one with the oil cup holders 11. The oil cups 6 can be fixedly connected to the oil cup holders 11. The moving cylinder drives the oil cups 6 to move back and forth on the steel plate 5 through the fixed horizontal plate 10 and the oil cup holders 11, thereby leaving ink in the pattern on the steel plate.

[0025] The printing head moving assembly is located above the ink table 3, the cleaning table 4, and the workpiece placement assembly. The printing head moving assembly includes a lifting cylinder (the lifting cylinder is located inside the top of the support frame and is not shown in the figure). The bottom of the lifting cylinder is fixedly connected to a slide rail 13 via a slide rail fixing seat 12. A slider 14 is slidably connected to the slide rail 13. A printing head fixing plate 15 is fixedly connected to the bottom of the slider. Three printing heads 16 are provided at the bottom of the printing head fixing plate.

[0026] The slider moves back and forth on the slide rail, which drives the pad printing head to move back and forth. The pad printing head can pick up ink on the steel plate and print the ink on the front panel 22 of the drawer on the workpiece placement table. The pad printing head can also remove residual ink on the cleaning tape.

[0027] The workpiece placement assembly includes a mounting base 17, a servo motor 18, and a workpiece placement stage 19. The workpiece placement stage is rotatably connected between the mounting base and the servo motor. The servo motor can drive the workpiece placement stage to rotate back and forth on the mounting base. The workpiece placement stage is equipped with positioning fixtures that can fix the front panel 22 of the three drawers.

[0028] The cleaning table is equipped with a drive roller 20 and a driven roller 21, and a cleaning tape is connected between the drive roller and the driven roller.

[0029] A drive motor is connected to the drive roller, which drives the drive roller to rotate, thereby moving the cleaning tape so that the cleaning tape can continue to remove ink.

[0030] The automatic pad printing equipment for the front panel of the drawer also includes a main controller, which is electrically connected to the moving cylinder 7, the lifting cylinder, the slider 14, the servo motor 18, and the drive motor.

[0031] The specific working process of this utility model is as follows: The operator fixes the front panel of the drawer on the workpiece placement table. If the front panel of the drawer is curved, the servo motor controls the workpiece placement table to rotate and adjust the position of the front panel of the drawer. Then, the moving cylinder moves back and forth on the steel plate 5 through the oil cup 6, thereby leaving ink in the pattern on the steel plate. Then, the slider moves backward, driving the pad printing head to move above the ink table 3. The lifting cylinder drives the pad printing head 16 to descend. After the pad printing head picks up ink on the steel plate, it rises. The slider drives the pad printing head to move above the front panel of the drawer. The lifting cylinder drives the pad printing head 16 to descend. The pad printing head prints ink on the front panel of the drawer on the workpiece placement table. Then, the slider drives the pad printing head to move above the cleaning tape. The lifting cylinder drives the pad printing head 16 to descend. The pad printing head removes residual ink on the cleaning tape. Finally, the drive motor drives the active roller to rotate, driving the cleaning tape to move and move the clean cleaning tape to the bottom of the pad printing head.
