[0002] In the metal stamping process, it is necessary to use a continuous die strip, that is, a strip of stamping raw material. A cold stamping die is used on a die to complete multiple stamping processes at the same time using several different workstations. Each time the die completes a stamping, the strip moves a fixed distance until the product is completed. During the stamping process, the strip is prone to jumping due to the vibration generated by the stamping of the stamping die. Therefore, an anti-jumping device is required to prevent the strip from jumping.

[0003] Although the existing anti-jumping device can be used for daily material belt anti-jumping operations, in actual use, the method of relying solely on roller tension to eliminate material belt jumping can reduce the material belt jumping amplitude to a certain extent, but the material belt will still jump during stamping, which makes the use effect of the anti-jumping device not good enough. In addition, when the material belt is conveyed, the material belt is prone to position deviation, requiring manual adjustment by the staff, which brings inconvenience to the staff's correction work, and thus makes the anti-jumping device less convenient to use.
