[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a plate roller gravity elimination mechanism, including plate cylinder 10, transmission lock hook fixing sleeve 20, reduction box 30, motor 40, cylinder one 50, plate cylinder supporting plate 60 and cylinder two 70;

[0023] The plate roller gravity elimination mechanism can be conveniently buffered, and the specific embodiment is as follows:

[0024] The plate cylinder 10 is provided in a cylindrical structure, and a transmission lock hook fixing sleeve 20 is mounted on one side surface of the plate cylinder 10. The end of the transmission lock hook fixing sleeve 20 is provided with a reduction box 30, and the end of the reduction box 30 is provided with a motor 40. The surface of the reduction box 30 is provided with a cylinder one 50. One side surface of the plate cylinder 10 is connected with a plate cylinder supporting plate 60, and the bottom of the plate cylinder supporting plate 60 is provided with a cylinder two 70. The transmission lock hook fixing sleeve 20 and the plate cylinder supporting plate 60 are symmetrically arranged on both sides of the plate cylinder 10. The output shaft of the motor 40 is connected with one side of the plate cylinder 10 through the reduction box 30 and the fixing sleeve 20. The end of the cylinder one 50 is provided with a reduction box 30 on the surface. The surface of the plate cylinder supporting plate 60 is attached to the bottom of one side of the plate cylinder 10. The plate cylinder 10 and the plate cylinder 10 are rotatably connected.

[0025] The paper is sleeved on the surface of the plate cylinder 10, and the motor 40 is started at the same time. The motor 40 drives the plate cylinder 10 to rotate through the reduction box 30. At this time, the reduction box 30 can drive the plate cylinder 10 to reduce the rotating speed. At this time, the plate cylinder 10 rotates to wind the paper on the surface of the plate cylinder 10, so that the other end of the plate cylinder 10 rotates on the surface of the plate cylinder supporting plate 60. At this time, the paper is wound on the surface of the plate cylinder 10, so that the diameter of the paper on the surface of the plate cylinder 10 increases, and the weight of the plate cylinder 10 increases. When the self-weight of the plate cylinder 10 is large, the plate cylinder 10 causes pressure on the two ends of the transmission lock hook fixing sleeve 20, the reduction box 30 and the plate cylinder supporting plate 60. The plate cylinder supporting plate 60 causes pressure on the cylinder two 70. At this time, the end of the cylinder two 70 is retracted. The fixing sleeve 20 and the reduction box 30 cause pressure on the cylinder one 50, so that the end of the cylinder one 50 is retracted. At this time, the cylinder one 50 and the cylinder two 70 drive the plate cylinder 10 to move downward, and buffer the two ends of the plate cylinder 10.

[0026] Working principle: when using the edition roller gravity elimination mechanism, the motor 40, the cylinder one 50, the plate cylinder supporting plate 60 and the cylinder two 70 are arranged, so that the buffer can be conveniently carried out, the pressure on both ends of the plate cylinder 10 can be reduced, the safety and service life of the plate cylinder 10 can be increased, and the overall practicability is increased.

[0027] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
