[0006] Preferably, the connecting shaft is connected to the external code disc wheel via a top screw.

[0007] Preferably, a mounting hole is provided on the mounting plate, and the mounting plate is fixedly connected to the housing of the labeling machine through the mounting hole.

[0008] Preferably, a groove is provided on the clamping ring, an anti-rotation shaft is provided in the groove, and the anti-rotation shaft is fixed on the inner shaft.

[0009] Preferably, the gasket between the clamping ring and the outer sleeve is a smooth gasket.

[0010] The beneficial effect of the present invention is that, by setting a tension spring, the rear wheel of the coding machine is tightened by mechanical means, which replaces the original driver, motor, and magnetic powder clutch, and avoids failures caused by continuous rotation; an adjusting nut is set, and the tensioning force can be adjusted in real time as needed. It is easy to use, has a low failure rate, and has a low device cost, thereby reducing the overall production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below in conjunction with embodiments.

[0017] like Figure 1-3 As shown, a code disc tensioning device for a code outputting machine adopts a mechanical method to realize the tensioning of the rear wheel, replacing the original driver, motor, and magnetic powder clutch of the rear wheel. The device is provided with a connecting shaft 8 and an inner shaft 3. The connecting shaft 8 and the inner shaft 3 are an integrated structure. The connecting shaft 8 is connected to the external code disc wheel through a top screw. An outer sleeve 5 is provided on the inner shaft 3. A mounting plate 6 is provided on the outer sleeve 5. A mounting hole 7 is provided on the mounting plate 6. The mounting plate 6 is fixedly connected to the outer shell of the label outputting machine through the mounting hole 7. Snap rings 4 are provided on both sides of the outer sleeve 5. A smooth gasket 9 is provided between the snap ring 4 and the outer sleeve 5. When the friction force is small, the outer sleeve 5 and the inner shaft 3 do not rotate synchronously. A groove is provided on the snap ring 4. An anti-rotation shaft 10 is provided in the groove. The anti-rotation shaft 10 passes through the inner shaft 3 and is fixed on the inner shaft 3. By providing the anti-rotation shaft 10, the synchronous rotation of the inner shaft 3 and the snap ring 4 can be achieved. A tension spring 2 and an adjusting nut 1 are provided on the side of the inner shaft 3 away from the connecting shaft 8. One end of the tension spring 2 is pressed against the retaining ring 4, and the other end is pressed against the adjusting nut 1. The tension of the tension spring 2 is adjusted by adjusting the nut 1, so that the retaining rings 4 on both sides clamp the outer sleeve 5, so that there is friction between the inner shaft 3 and the outer sleeve 5. The greater the tension, the greater the friction.

[0018] The tensioning device achieves the tensioning effect of the rear wheel code disc when the marking machine prints codes by fixing the mounting plate 6 to the housing of the marking machine and the connecting shaft 8 to the code disc wheel, thereby achieving a smooth code printing effect, and the installation and adjustment are convenient and simple, and the failure rate is low.

[0019] After the new device is installed, it can replace the rear wheel drive, motor, and magnetic powder clutch of the code output machine, saving about 1,500 yuan per unit. The transformation test has been completed and the effect is good, achieving the expected effect. The failure rate has been reduced by more than 50%, which has been widely recognized by users.

[0020] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the present invention should still fall within the scope covered by the claims of the present invention.
