Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a printing roller adjustment component. Background Technology

[0002] A gravure printing press is a machine that uses a gravure plate for printing. During printing, the entire surface of the printing plate cylinder is inked. A doctor blade scrapes away the ink from the blank areas of the plate, leaving the ink for the image areas. Then, the plate passes over the substrate, and the impression cylinder presses the impression onto the back of the substrate, allowing the ink in the recessed areas to be directly transferred to the surface of the substrate.

[0003] Currently, the prior art CN215792437U discloses a printing roller adjustment mechanism for a gravure printing machine, including a printing roller assembly, a lifting adjustment assembly, and a rotating assembly. The printing roller assembly includes a left support, and a right support is provided on the right side of the left support. The lifting adjustment assembly is fixedly installed on the inner wall of the right support. The lifting adjustment assembly includes a servo motor, which is fixedly installed on the inner wall of the right support. The output end of the servo motor is fixedly connected to a screw, and a bevel gear is fixedly installed on the outer wall of the bottom end of the screw. The left and right supports are movably connected by a transmission shaft through bearings. The two ends of the transmission shaft extend to the inner walls of the left and right supports. By setting the servo motor to drive both screws to rotate simultaneously, the screws are raised or lowered synchronously by being threadedly connected to threaded sleeves on the left and right sides, respectively, which facilitates the adjustment of the height of both ends of the printing roller.

[0004] However, in the above scheme, the weight (pressure) of the adjustment mechanism is entirely applied to the servo motor at the bottom, which can easily damage the internal components of the servo motor. Furthermore, it can only adjust the vertical direction of the same type of printing roller, making it less practical. Utility Model Content

[0011] Preferably, the drive assembly includes racks symmetrically arranged at the bottom of the inner wall of the adjustment plate, drive wheels meshing with the racks on both sides, and a drive motor with an output shaft fixedly connected to the drive wheels on the mounting bracket.

[0012] The beneficial effects of this utility model are:

[0013] By activating the drive assembly, the mounting frame extends and retracts along the adjusting plate, thereby adjusting the distance between the mounting slots on both sides. The pressure block rotates and fixes both ends of the printing roller in the middle of the mounting slot, realizing the centering and fixing of printing rollers of different lengths. Then, by controlling the lifting motors on both sides to drive the lead screws on both sides to rotate synchronously, the adjusting plates on both sides drive the printing rollers to rise and fall synchronously, conveniently realizing the height adjustment of printing rollers of different lengths and improving the practicality of the equipment.

[0019] 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.

[0020] Please see Figures 1 to 4 This utility model provides a printing roller adjustment assembly, including a base frame 1. Lifting assemblies 2 are symmetrically arranged on both sides of the base frame 1. An adjusting plate 3 is lifted and lowered in the middle of the lifting assembly 2. A mounting frame 4 is telescopically mounted in the middle of the adjusting plate 3. One end of the mounting frame 4 has a mounting groove 5. Printing rollers 6 are mounted on both sides of the mounting grooves 5. A pressure block 7 for fixing the printing rollers 6 is detachably mounted on the top of the mounting grooves 5. A driving assembly 8 for driving the mounting frame 4 to extend and retract is provided in the middle of the adjusting plate 3. By activating the driving assembly 8, the mounting frame 4 extends and retracts along the adjusting plate 3, thereby adjusting the distance between the two mounting grooves 5. The pressure block 7 rotates and fixes both ends of the printing rollers 6 in the middle of the mounting grooves 5, achieving centered and fixed installation of printing rollers 6 of different lengths. Furthermore, by controlling the lifting motors 22 on both sides to drive the lead screws 21 on both sides to rotate synchronously, the adjusting plates 3 on both sides drive the printing rollers 6 to rise and fall synchronously. This conveniently achieves height adjustment of printing rollers 6 of different lengths, improving the practicality of the equipment.

[0021] like Figure 1 As shown, specifically, the base frame 1 is U-shaped, and the bottom of the base frame 1 is provided with several waist-shaped grooves 9. By passing bolts through the waist-shaped grooves 9, the base frame 1 is fixedly installed on the mounting base surface, thereby improving the stability of the base frame 1.

[0022] Specifically, the lifting assembly 2 includes a lead screw 21 rotatably mounted on the side of the base frame 1, and a lifting motor 22 fixedly connected to the end of the lead screw 21 on the same side at the top of the base frame 1. By controlling the lifting motors 22 on both sides to drive the lead screws 21 on both sides to rotate synchronously, the adjusting plates 3 on both sides can be conveniently driven to drive the printing rollers 6 to rise and fall synchronously. Moreover, the lead screws 21 on both sides bear most of the pressure, thereby improving the reliability of the equipment.

[0023] like Figure 2 As shown, specifically, one side of the adjusting plate 3 is threadedly connected to the lead screw 21 and has a threaded hole 31. The inner wall of the adjusting plate 3 is symmetrically provided with support grooves 32. By threading the threaded hole 31 of the adjusting plate 3 to the lead screw 21, it is convenient for the lead screws 21 on both sides to drive the adjusting plate 3 on the same side to rise and fall synchronously, so as to conveniently realize the adjustment of the height of the printing roller 6.

[0024] Specifically, the inner wall of the adjustment plate 3 is symmetrically provided with guide rails 10, and the mounting frame 4 is slidably connected to the guide rails 10 on both sides through a slider 11. When the mounting frame 4 extends and retracts along the support groove 32 in the middle of the adjustment plate 3, it slides along the guide rails 10 through the slider 11, which further improves the stability during the extension and retraction process.

[0025] like Figure 3 As shown, specifically, the drive assembly 8 includes racks 81 symmetrically arranged at the bottom of the inner wall of the adjustment plate 3, and drive wheels 82 meshing with the racks 81 on both sides. The mounting frame 4 is provided with a drive motor 83 whose output shaft is fixedly connected to the drive wheels 82. By starting the drive motor 83, the drive wheels 82 are driven to rotate synchronously, thereby meshing with the racks 81 on both sides. The drive mounting frame 4 extends and retracts along the support groove 32 in the adjustment plate 3, which conveniently adjusts the distance between the two mounting frames 4, and conveniently realizes the fixed installation of printing rollers 6 of different lengths.

[0026] The working principle of this utility model is as follows: When in use, the drive motor 83 is started, which causes the drive wheel 82 to mesh with the racks 81 on both sides, driving the mounting frame 4 to extend and retract along the adjusting plate 3, thereby adjusting the distance between the mounting slots 5 on both sides, so as to realize the centering and fixed installation of printing rollers 6 of different lengths. Then, by controlling the lifting motors 22 on both sides to drive the lead screws 21 on both sides to rotate synchronously, the adjusting plates 3 on both sides drive the printing rollers 6 to rise and fall synchronously, so as to conveniently realize the height adjustment of printing rollers 6 of different lengths and improve the practicality of the equipment.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
