Description

Technical Field

[0001] This utility model relates to the field of printing calibration technology, specifically a calibration device for color printing of paper boxes. Background Technology

[0002] Multicolor printing is a printing process that involves printing different colored inks in layers onto paper or other materials to form the final image or design. This technique typically uses four-color printing to achieve richer color combinations. When printing multicolor on paper boxes, the center line of the printing plate often does not align with the engraved line in the middle of the cylinder, resulting in incorrect plate positioning and inaccurate registration, which affects the quality of multicolor printing on paper boxes. To address this issue, we propose a multicolor printing calibration device for paper boxes. Utility Model Content

[0003] The purpose of this invention is to provide a paper box color printing calibration device to solve the problems mentioned in the background art.

[0005] The calibration mechanism includes two symmetrically distributed first bearings, which are respectively fixedly clamped to the top of the first and second longitudinal frames. Each first bearing has an inner sliding cylinder fixedly clamped in the middle, and an installation sleeve is slidably clamped in the middle of the inner sliding cylinder.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-4 As shown, this utility model provides a paper box color printing calibration device, including a mounting base 1 and a first vertical frame 2. Two symmetrically distributed horizontal slide seats 11 are fixedly installed on the top of the mounting base 1. The top of the horizontal slide seats 11 is slidably fitted with a second vertical frame 3. The second vertical frame 3 facilitates stable translation and sliding. A printing roller 4 is provided between the first vertical frame 2 and the second vertical frame 3. A calibration mechanism 5 is provided between the first vertical frame 2 and the second vertical frame 3 and the printing roller 4.

[0023] The calibration mechanism 5 includes two symmetrically distributed first bearings 51. The first bearings 51 are respectively fixedly clamped to the top of the first longitudinal frame 2 and the second longitudinal frame 3. The middle of each first bearing 51 is fixedly clamped with an inner slide cylinder 52, which facilitates rotation at the top of the first longitudinal frame 2 and the second longitudinal frame 3. The middle of the inner slide cylinder 52 is slidably clamped with an installation sleeve 53, which facilitates translation and sliding within the inner slide cylinder 52. When the inner slide cylinder 52 rotates, the installation sleeve 53 can be controlled to rotate. The two ends of the printing roller 4 are respectively fixedly clamped to the corresponding installation sleeves 53 by bolts, thereby fixing the printing roller 4 and the two side installation sleeves 53 with bolts. This facilitates the removal of the bolts to disassemble the printing roller 4. When the installation sleeves 53 rotate, the printing roller 4 can be controlled to rotate, thereby using the printing roller 4 to perform color printing on the paper box.

[0024] One of the mounting sleeves 53 is fixedly mounted with a second bearing 54 at the end away from the printing roller 4, and a translation frame 541 is fixedly mounted on the outer side of the second bearing 54; a telescopic cylinder 542 is fixedly mounted in the middle of the first longitudinal frame 2, and the driving end of the telescopic cylinder 542 is fixedly mounted on the bottom of the translation frame 541. By controlling the opening of the telescopic cylinder 542, the translation frame 541 is driven to rotate one of the mounting sleeves 53, thereby driving the printing roller 4 to slide horizontally, thereby automatically calibrating the printing roller 4, aligning the center line of the paper box printing plate with the engraved line in the middle of the printing roller 4, preventing the printing plate from being misaligned and causing inaccurate registration, thereby improving the quality of color printing of the paper box.

[0025] A drive shaft 55 is rotatably mounted at the bottom center of the first longitudinal frame 2. A first transmission wheel 551 is fixedly mounted on the outer side of the drive shaft 55. A second transmission wheel 552 is fixedly mounted on the end of the inner slide cylinder 52 near the second bearing 54. A transmission belt 553 is movably sleeved on the outer side of the first transmission wheel 551 and the second transmission wheel 552. A first motor 56 is fixedly mounted on the side of the first longitudinal frame 2 near the drive shaft 55. The drive end of the first motor 56 is fixedly mounted to one end of the drive shaft 55. In use, the first motor 56 is turned on to drive the drive shaft 55 to rotate. With the transmission of the first transmission wheel 551, the second transmission wheel 552 and the transmission belt 553, the inner slide cylinder 52 is driven to rotate, thereby controlling the rotation of the mounting sleeve 53.

[0026] A translation screw 12 is rotatably mounted in the middle of the mounting base 1, and the bottom thread of the second longitudinal frame 3 is threaded onto the outside of the translation screw 12. A second motor 13 is fixedly mounted on the top of the mounting base 1 near the translation screw 12. The drive end of the second motor 13 and one end of the translation screw 12 are fixedly mounted. When the printing roller 4 needs to be disassembled for maintenance, the second motor 13 is turned on to drive the translation screw 12 to rotate, thereby moving the second longitudinal frame 3 to control the corresponding position of the first bearing 51 and inner slide cylinder 52 to move. The bolts at this position are removed, and one end of the printing roller 4 is removed from the corresponding mounting sleeve 53. The bolts at the other end are then removed by translation. Subsequently, the second longitudinal frame 3 is translated and removed from the printing roller 4 for quick disassembly and maintenance of the printing roller 4, thereby improving the overall performance of the paper box color printing equipment.

[0027] Working principle: When in use, the first motor 56 is turned on to drive the drive shaft 55 to rotate. With the transmission of the first transmission wheel 551, the second transmission wheel 552 and the transmission belt 553, the inner slide cylinder 52 is driven to rotate, thereby controlling the installation sleeve 53 to rotate, and controlling the printing roller 4 to rotate, so that the printing roller 4 can be used to perform color printing on the paper box.

[0028] During printing, the telescopic cylinder 542 can be controlled to drive the translation frame 541 to rotate one of the mounting sleeves 53, thereby driving the printing roller 4 to slide and translate, thus automatically calibrating the printing roller 4, aligning the center line of the paper box printing plate with the engraved line in the middle of the printing roller 4, preventing the printing plate from being misaligned and causing inaccurate registration, thereby improving the quality of color printing on the paper box.

[0029] When the printing roller 4 needs to be disassembled for maintenance, the second motor 13 is activated to drive the translation screw 12 to rotate, which in turn moves the second longitudinal frame 3 to control the movement of the first bearing 51 and inner slide cylinder 52 at the corresponding positions. The bolts at that position are then removed, and one end of the printing roller 4 is detached from the corresponding mounting sleeve 53. The bolts at the other end are then removed by continuing to move the frame. Subsequently, the second longitudinal frame 3 is moved to detach from the printing roller 4, allowing for quick disassembly and maintenance of the printing roller 4 and improving the overall performance of the paper box color printing equipment.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
