Anti-skid device on biscuit roll printing machine

An anti-skid device used on a biscuit roll printing machine adopts the scheme that a right-angled auxiliary bracket is welded in front of a machine base loaded with three tension regulating beam barrels, an upper pressure roll and a lower pressure roll are sleeved on a vertical arm of the auxiliary bracket in a penetrating manner, a rubber roll with the diameter larger than 10cm is mounted on a cross arm of the auxiliary bracket, and a conveyor belt turning back from a redirection roll of the roll printing machine bypasses the upper pressure roll, the rubber roll, the lower pressure roll and the three tension regulating beam barrels in sequence. The anti-skid device is characterized in that the conveyor belt is prevented from skidding on the beam barrels, so that the production efficiency is improved.
