Description

Technical Field

[0001] The utility model relates to the technical field of printing rollers, in particular to a printing roller with adjustable pressure. Background Art

[0002] Printing roller is a printing process that continuously transfers the printing paste to the surface of the fabric by engraving patterns or designs on the outer wall of the metal roller and continuously rotating it mechanically. It is often used in plastic bag production operations.

[0003] At present, the patterns of most printing rollers on the market are usually engraved on the outer wall of the roller. When thicker products need to be printed, in order to make the products have better printing effects, it is necessary to replace the printing roller with a slightly larger diameter to increase the printing pressure and thus improve the printing effect.

[0004] The printing roller is driven by the printing machine to rotate, and the printing roller is usually installed with the printing machine by flange. When the printing roller needs to be replaced, multiple bolts need to be removed, and multiple bolts need to be installed during installation. It is very troublesome to disassemble and inconvenient to use. Utility Model Content

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a printing roller with adjustable pressure, comprising a printing roller body 1, an adjusting mechanism 2 is arranged inside the printing roller body 1, and the printing pressure of the printing arc plate 27 can be adjusted by setting the adjusting mechanism 2, so as to print products of different thicknesses, and a cleaning mechanism 3 is arranged inside the printing roller body 1, and impurities attached to the surface of the printing arc plate 27 can be cleaned by setting the cleaning mechanism 3, so that the printing arc plate 27 can better print the product.

[0024] The above-mentioned adjustment mechanism 2 includes a rotating rod 21, a frame 22, a threaded rod 23, a knob 24, a driving bevel gear 25, a driven bevel gear 26, and a printing arc plate 27; the rotating rod 21 is rotatably connected to the inner wall of the printing roller body 1, and the rotating rod 21 passes through the printing roller body 1, and the rotating rod 21 is rotatably connected to the penetration of the printing roller body 1, one end of the rotating rod 21 is fixedly installed with a knob 24, and the other end of the rotating rod 21 is fixedly installed with a driving bevel gear 25, and the rotating rod 21 is rotated by rotating the knob 24, so that the rotating rod 21 drives the driving bevel gear 25 to rotate, the frame 22 is slidably connected to the inner wall of the printing roller body 1, and the side wall of the frame 22 is fixedly installed with a printing arc plate 27, and the outer wall of the printing arc plate 27 is attached to the inner wall of the printing roller body 1, and the sliding of the frame 22 can drive the printing arc plate 27 to gradually move out to the outside of the printing roller body 1, when the arc surface of the printing arc plate 27 When it is flush with the outer wall of the printing roller body 1, the product can be printed using the printing arc plate 27. When the printing pressure needs to be increased, the printing arc plate 27 is driven by the frame 22 to continuously slide out to the outside of the printing roller body 1 and protrude from the printing roller body 1. By protruding the printing arc plate 27 from the printing roller body 1, the pressure of squeezing the product can be increased, thereby being able to cope with thicker products. One end of the threaded rod 23 is rotatably connected to the inner wall of the printing roller body 1, and the other end of the threaded rod 23 is fixedly installed with a driven bevel gear 26, which is meshed with the driving bevel gear 25. When the driving bevel gear 25 rotates, the driven bevel gear 26 meshed with it can drive the threaded rod 23 to rotate. The frame 22 is threadedly connected to the outer wall of the threaded rod 23, and the rotation of the threaded rod 23 can drive the frame 22 threadedly connected to it to slide on the inner wall of the printing roller body 1.

[0025] The above-mentioned cleaning mechanism 3 includes a brush 31 and a push block 32; the brush 31 is slidably connected to the inner wall of the printing roller body 1, and the push block 32 is fixedly installed on the outer wall of the brush 31. The push block 32 is used to push the brush 31 so that the brush 31 slides on the inner wall of the printing roller body 1. The brush 31 fits on the outer wall of the printing arc plate 27. While the brush 31 slides, it can clean the impurities attached to the surface of the printing arc plate 27, so that the printing arc plate 27 can better print the product.

[0026] Working principle: by rotating the rotating rod 21 through the knob 24, the rotating rod 21 drives the driving bevel gear 25 to rotate. While the driving bevel gear 25 rotates, the driven bevel gear 26 meshing with it can drive the threaded rod 23 to rotate. The rotation of the threaded rod 23 can drive the frame 22 threadedly connected to it to slide on the inner wall of the printing roller body 1. The sliding of the frame 22 can drive the printing arc plate 27 to gradually move out to the outside of the printing roller body 1. When the arc surface of the printing arc plate 27 is flush with the outer wall of the printing roller body 1, the printing arc plate 27 can be used to print the product. When it is necessary to increase the printing pressure, the printing arc plate 27 is driven by the frame 22 to continuously slide out to the outside of the printing roller body 1 and protrude the printing roller body 1. By protruding the printing arc plate 27 from the printing roller body 1, the pressure of squeezing the product can be increased, so that thicker products can be handled. There is no need to replace the printing roller body 1 to print products of different thicknesses, which is more convenient to use.

[0027] When the printing arc plate 27 needs to be cleaned, the frame 22 is first used to drive the printing arc plate 27 into the interior of the printing roller body 1 to expose the brush 31. At this time, the push block 32 is used to push the brush 31 to slide on the inner wall of the printing roller body 1. While the brush 31 slides, impurities attached to the surface of the printing arc plate 27 can be cleaned, so that the printing arc plate 27 can better print the product.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
