Technical Field

[0001] The utility model relates to the technical field of transmission wheels, in particular to a seismic-resistant locking mechanism for a unidirectional medium- and low-speed rotating transmission wheel. Background Art

[0002] The inkjet roller conveyor usually refers to the equipment or system used to print date, batch number, barcode and other information on the production line. It is mainly composed of an inkjet printer and a roller conveyor system.

[0003] The inkjet roller requires that all three lines of the rollers are consistent in order to smoothly transport the steel pipe and print the product logo on the outer wall of the steel pipe. However, after a period of use, it is inevitable that the vibration will cause different degrees of looseness and displacement, resulting in distortion of the printed information. In addition, the existing inkjet rollers are all fixed in length for installation, which is inconvenient to transport and install.

[0004] Therefore, there is an urgent need for a vibration-resistant locking mechanism for a unidirectional medium- and low-speed rotating transmission wheel to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a vibration-resistant locking mechanism for a one-way medium- and low-speed rotating transmission wheel, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0007] A seismic locking mechanism for a one-way medium- and low-speed rotating transmission wheel comprises a main base, the outer wall of which is detachably connected to a symmetrically distributed auxiliary base, the outer wall of which is fixedly connected to a support block, and further comprises:

[0008] A support block, fixedly connected to the outer wall of the main base, wherein the top wall of the support block is fixedly connected to a second motor;

[0010] A sliding seat is fixedly connected to the outer wall of the main base, the inner wall of the sliding seat is slidably connected to a lifting block, and the lifting block and the top wall of the mounting seat are both fixedly connected to symmetrically distributed bearing seats;

[0011] The anti-slip locking component is arranged on the inner wall of the bearing seat.

[0012] As a preferred technical solution of the present application, the anti-slip locking assembly includes a roller shaft fixedly connected to the inner wall of the bearing seat, and the outer wall of the roller shaft in the middle is fixedly connected to the output end of the second motor, the outer wall of the roller shaft is fixedly connected to a support wheel, the outer wall of the roller shaft is threadedly connected to a first anti-slip nut, the outer wall of the roller shaft is threadedly connected to a second anti-slip nut, a fastening washer is arranged between the support wheel and the second anti-slip nut, and the outer wall of the fastening washer and the outer wall of the support wheel are provided with evenly distributed anti-slip patterns.

[0013] As a preferred technical solution of the present application, the outer wall of the fastening washer abuts against the outer wall of the supporting wheel, and the outer wall of the fastening washer abuts against the outer wall of the second anti-slip nut.

[0017] In the scheme of this application:

[0018] 1. The threads between the first anti-slip nut and the second anti-slip nut and the roller shaft are matched and the iron rod is vibrated and rotated into place, so that the fastening pad iron is close to the supporting wheel and the anti-slip nut, and the anti-slip pattern is provided so that the surface between the fastening pad iron and the supporting wheel is roughened, thereby increasing the friction force. The interior of the fastening pad iron is a semi-hollow structure, which can form a closed small space between the supporting wheel, thereby effectively collecting the sundries and debris generated by the vibration and friction of the supporting wheel. The longer the equipment is used, the larger the volume of the debris after rusting, thereby better ensuring the completeness and effectiveness of the entire structure, thereby avoiding loosening and displacement, and solving the problem that the inkjet roller in the prior art will inevitably loosen and displace to varying degrees due to vibration after a period of use, causing the printed information to be distorted;
