[0002] In the production of environmentally friendly color boxes, paper slitting is a crucial preliminary process. Its function is to cut large sheets of raw paper into the required narrow strips according to design specifications for subsequent printing, die-cutting, and other processing. The quality of slitting directly affects the production efficiency of subsequent processes and the quality of the final product. Currently, common slitting devices on the market typically use fixed upper and lower cutting rollers for shearing. A search revealed a utility model patent with patent authorization publication number CN218054191U, which discloses a paper slitting machine for environmentally friendly color box production. This machine includes an assembly chassis, a buffer device on the underside of the chassis, a buffer rod fixed to the underside of the chassis, a tensioning device on the rear side of the chassis, a first fixed seat of the tensioning device fixed to the chassis, and a cutting device on the front side of the chassis.
[0003] However, in existing technologies, traditional pressure regulating mechanisms often use simple screws for direct pressure application. After long-term use, the threaded joints are prone to jamming due to wear and lack of lubrication, resulting in uneven adjustment. Therefore, improvements are needed. Utility Model Content

[0023] Please see Figures 3-4 A lubrication mechanism 9 is provided at the upper end of the top plate 5 and outside the adjusting rod 6. The lubrication mechanism 9 provides lubrication for the adjusting rod 6 used to adjust the pressure roller 10. The lubrication mechanism 9 includes an oil storage box 91 fixedly connected to the upper end of the top plate 5. The oil storage box 91 is slidably connected to the outside of the adjusting rod 6. A sponge block 92 and an inclined block 93 are slidably connected inside the oil storage box 91, and the sponge block 92 and the inclined block 93 are in contact with each other. A sliding pin 94 is slidably connected to the upper end of the oil storage box 91, and the sliding pin 94 penetrates the oil storage box 91. The lower end of the sliding pin 94 abuts against the inclined surface of the inclined block 93. A pressure ring 95 is fixedly connected to the upper end of the sliding pin 94, and the pressure ring 95 is located outside the adjusting rod 6. The pressure ring 95 facilitates the downward pressure of the sliding pin 94. A guide pin 96 is fixedly connected to the inner wall of the oil reservoir 91.

[0024] The specific implementation process of this utility model is as follows: First, the paper roll is guided through the space between the first rubber roller 14 and the second rubber roller 16, and between the groove roller 13 and the cutter roller 15. The hydraulic cylinder 3 is activated, and its telescopic shaft pushes the top plate 5 down as a whole through the connecting block 4 until the cutter roller 15 approaches the groove roller 13 and the second rubber roller 16 approaches the first rubber roller 14. Then, the adjusting rod 6 is rotated through the rotating wheel 11. Since the adjusting rod 6 is threadedly connected to the top plate 5, its rotational motion is converted into linear lifting motion. The adjusting rod 6 pushes the frame 8 and its two internal pressure rollers 10 to rise and fall together through the bearing seat 7, thereby utilizing the pressure... The force roller 10 adjusts the tension of the paper. After all settings and adjustments are completed, the device can be started for paper slitting. Additionally, pressing down on the pressure ring 95 by hand pushes the sliding pin 94 downwards. The lower end of the sliding pin 94 presses against the inclined surface of the inclined block 93, forcing the inclined block 93 to overcome the elastic force of the spring 97 and slide laterally along the guide pin 96. During the movement of the inclined block 93, it presses against the sponge block 92, squeezing out the lubricating oil stored in the sponge block 92. This oil is then evenly applied to the threaded surface of the adjusting rod 6 through the oil outlet 98, thus performing regular maintenance on the adjusting rod 6 to prevent rust and jamming.
[0025] 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.
