DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A paper roll creasing mechanism comprises a frame 1, the outer walls of both sides of the frame 1 are provided with slide grooves 9, hydraulic cylinders 3 are respectively installed in the slide grooves 9 and on the upper end surface of the frame 1, the telescopic ends of the two groups of hydraulic cylinders 3 are fixedly connected with adjustment plates 17, the inner wall of the adjustment plate 17 is rotatably connected with a creasing roller 2, the upper end surface of the frame 1 is fixedly connected with a pressing seat 5 corresponding to the position of the creasing roller 2, a reciprocating screw 10 is rotatably connected between the two groups of adjustment plates 17, the reciprocating screw 10 is connected with a connecting rod 16 through a connecting mechanism, the end of the connecting rod 16 is fixedly connected with a brush plate 13, and the brush plate 13 The inner and outer walls are both annular, and the brush plate 13 contacts the upper end surface of the creasing roller 2. The connecting mechanism includes a screw sleeve 12 threadedly connected to the threaded section of the reciprocating screw 10. Two sets of connecting grooves 14 are provided on the lower end surface of the screw sleeve 12. The connecting rod 16 is slidably connected inside the connecting groove 14. The reciprocating screw 10 drives the screw sleeve 12 to drive the brush plate 13 to slide. During the operation of the creasing roller 2, impurities attached to the outer wall thereof can be cleaned to ensure the quality of the creasing when the roll paper is creasing. At the same time, the surface area of ​​the brush plate 13 is small, and the cost of replacement is lower.

[0022] Reference Figure 4 The tops of the two sets of connecting grooves 14 are fixedly connected with springs 15, and the other ends of the springs 15 are fixedly connected with the connecting rod 16. With the help of the elastic properties of the springs 15, when the brush plate 13 cleans the groove of the indentation roller 2, the bristles on the brush plate 13 can be pressed into the inside of the groove, thereby ensuring the cleaning effect.

[0023] Reference Figure 2 and Figure 3 A limit rod 11 is fixedly connected between the two groups of adjustment plates 17, and the screw sleeve 12 is slidably connected to the outer wall of the limit rod 11. The outer wall of one group of adjustment plates 17 is rotatably connected with a transmission wheel 16 and a transmission wheel 27. The transmission wheel 16 is coaxially fixedly connected to the creasing roller 2, and the transmission wheel 27 is coaxially fixedly connected to the reciprocating screw 10. The radius of the transmission wheel 16 is larger than the radius of the transmission wheel 27. The transmission wheel 16 is connected to the transmission wheel 27 through a transmission belt 8. The transmission wheel 16 and the transmission wheel 27 can synchronously drive the reciprocating screw 10 to rotate when the creasing roller 2 rotates. At the same time, the radii set by the two are inconsistent. When driving the reciprocating screw 10 to rotate, it is an accelerated motion.

[0024] Reference Figure 1 Another set of adjustment plates 17 is fixedly connected to the outer wall with a servo motor 4, and the output shaft of the servo motor 4 is coaxially fixedly connected with the creasing roller 2. The servo motor 4 can provide a power output source for the rotation of the creasing roller 2.

[0025] In the utility model, when using the device, the roll of paper to be indented is placed between the indentation roller 2 and the pressing seat 5, and the telescopic ends of the two groups of hydraulic cylinders 3 are extended and retracted to drive the adjustment plate 17 and the indentation roller 2 to slide downward until they contact the outer wall of the roll of paper, and then the servo motor 4 is started, and the servo motor 4 drives the indentation roller 2 to rotate. The cooperation of the indentation roller 2 and the pressing seat 5 can emboss the roll of paper, and in this process, the transmission wheel 1 6 and the transmission wheel 2 7 are used to synchronously drive the reciprocating screw 10 to rotate rapidly when the indentation roller 2 rotates, and then the screw sleeve 12 on its threaded section drives the brush plate 13 to slide back and forth on the upper end surface of the indentation roller 2, and impurities attached to the outer wall of the indentation roller 2 can be cleaned during sliding, and the spring 15 can ensure that the bristles on the brush plate 13 are pressed into the groove on the indentation roller 2 during cleaning, thereby improving the cleaning effect when cleaning the indentation roller 2 and ensuring the effect of indenting the roll of paper.

[0026] It is worth mentioning that, when cleaning the creasing roller 2, the existing devices mostly use a cleaning brush with the same length as the creasing roller 2. However, when the present device is in operation, the creasing roller 2 can be cleaned by driving the brush plate 13 to slide. At the same time, the surface area of ​​the brush plate 13 is small, and the cost of replacement is lower.

[0027] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
