DETAILED DESCRIPTION

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 5 , the present invention provides a plate roller that is convenient to adjust the balance, including a rotating shaft 1. A roller 2 is sleeved outside the rotating shaft 1. Fixing frames 3 for fixing the roller 2 are provided on both sides of the rotating shaft 1 in a threaded connection. A plurality of guiding grooves 4 are annularly formed in the middle of the rotating shaft 1. Adjusting grooves 5 corresponding to the guiding grooves 4 are provided on the inner side wall of the roller 2. Adjusting components 6 are jointly installed in the guiding grooves 4 and the adjusting grooves 5 on the same side. By rotating the fixing frames 3 on both sides along the thread one 11 on the rotating shaft 1, the installation or disassembly of the roller 2 on the outer circumferential wall of the rotating shaft 1 is realized. When the roller 2 is unbalanced during the rotation and printing process, by disassembling the rotating shaft 1 and the roller 2, an appropriate amount of counterweight balls 63 are added to the adjusting cavity 62 in the adjusting component 6, and then the adjusting frame 61 in the adjusting component 6 is moved along the guiding groove 4 and the adjusting groove 5 on the same side to the uneven mass position of the roller 2, and then the roller 2 is fixedly installed outside the rotating shaft 1, improving the stability of the roller 2 during rotation and the convenience of adjusting the stability of the roller 2.

[0022] As Figure 3 and Figure 4 shown, specifically, threads one 11 are symmetrically provided on both sides of the rotating shaft 1, and a plurality of positioning rods 12 are annularly provided on the outer circumferential wall of the rotating shaft 1 near one of the threads one 11. By providing the threads one 11, it is convenient to be in threaded cooperation with the fixing frames 3, so that the fixing frames 3 realize the installation and disassembly of the roller 2 during rotation.

[0023] Specifically, fixing cavities 21 are symmetrically opened on both sides of the roller 2, and a positioning groove 22 for clamping the positioning rod 12 is opened on the bottom wall of one of the fixing cavities 21. During the installation process of the rotating shaft 1 and the roller 2, by making the positioning rod 12 engage with the corresponding positioning groove 22, and then locking the positioning rod 12 into the positioning groove 22 by the fixing frame 3 on this side, the convenience and stability of the installation of the rotating shaft 1 and the roller 2 are improved.

[0024] As Figure 1 shown, specifically, the fixing frame 3 is in a funnel shape, and a thread two 31 that is in threaded connection with the thread one 11 is provided on one side of the fixing frame 3. By the threaded cooperation of the thread two 31 and the thread one 11, the fixing frames 3 on both sides clamp and fix the roller 2 to the middle of the rotating shaft 1.

[0025] Specifically, the guiding groove 4 is T-shaped, and the adjusting groove 5 is square. By moving the adjusting frame 61 along the guiding groove 4 and the adjusting groove 5 on the same side, it is convenient to move the adjusting frame 61 to the uneven mass position of the roller 2, and compensate by adding counterweight balls 63, thereby improving the stability when the roller 2 rotates.

[0026] As Figure 5 shown, specifically, the adjusting assembly 6 includes an adjusting frame 61 movably adjusted jointly in the guiding groove 4 and the adjusting groove 5 on the same side. The adjusting frame 61 is provided with a plurality of adjusting cavities 62 at one end of the adjusting groove 5. A counterweight ball 63 is detachably arranged in the adjusting cavity 62. By adding an appropriate amount of counterweight balls 63 into the adjusting cavities 62 on the adjusting frame 61, and moving the adjusting frame 61 along the guiding groove 4 and the adjusting groove 5 on the same side to the uneven mass position of the roller 2 for compensation, the dynamic balance of the roller 2 is improved, and the convenience of adjusting the stability of the roller 2 and the cost reduction for improvement are enhanced.

[0027] Specifically, the adjusting frame 61 is T-shaped. The bottom of the adjusting frame 61 is slidably connected to the guiding groove 4. Threaded holes 611 are symmetrically arranged at the bottom of the adjusting frame 61. The adjusting frame 61 is fixed to the outer circumferential wall of the rotating shaft 1 by bolts 7. By matching the bolts 7 with the threaded holes 611 at the bottom of the adjusting frame 61, the adjusting frame 61 moved to the corresponding position is fixed to the rotating shaft 1, thereby improving the stability of the rotation and printing of the roller 2.

[0028] Specifically, the side surface of the adjusting frame 61 at one end of the adjusting groove 5 is in contact with the inner wall of the adjusting groove 5. The counterweight balls 63 are respectively tangent to the inner wall of the adjusting groove 5 and the inner wall of the adjusting cavity 62, thereby improving the stability of the counterweight balls in the adjusting cavity 62.

[0029] The working principle of the present utility model: When in use, by rotating the two fixing frames 3 along the first thread 11 on the rotating shaft 1, the installation or disassembly of the roller 2 on the outer circumferential wall of the rotating shaft 1 is realized. When the roller 2 is unbalanced during the rotation and printing process, by disassembling the rotating shaft 1 and the roller 2, and then adding an appropriate amount of counterweight balls 63 into the corresponding adjusting cavities 62 of the adjusting frame 61, and then moving the adjusting frame 61 along the guiding groove 4 and the adjusting groove 5 on the same side to the uneven mass position of the roller 2, the stability when the roller 2 rotates and the convenience of adjusting the stability of the roller 2 are improved.

[0030] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model.
