The application relates to the technical field of waterproof roll production, and discloses a waterproof roll extrusion forming equipment and a waterproof roll production system. The waterproof roll extrusion forming equipment comprises a rack, a main compression roller assembly, an auxiliary compression roller assembly and a swing driving device. The main compression roller assembly is used for compressing the waterproof roll and comprises a plurality of main compression rollers arranged in sequence on the rack along a straight line. The auxiliary compression roller assembly is arranged on one side of the main compression roller assembly and comprises an auxiliary compression roller, a rotating shaft and a swing arm. The swing arm is pivotally installed on the rack through the rotating shaft, and the auxiliary compression roller is connected to the swing end of the swing arm. The swing driving device is used for driving the swing arm to swing around the rotating shaft to drive the auxiliary compression roller to compress the waterproof roll on one of the plurality of main compression rollers. The waterproof roll extrusion forming equipment and the waterproof roll production system can realize multi-roller extrusion and can accurately adjust the roller gap and the pressure, so that the dipped material is uniformly distributed on the tire cloth, and the product quality of the waterproof roll is effectively improved.

The utility model discloses a gummed paper compression roller convenient to adjust, which comprises a base, a lower rotating roller is rotatably arranged on the inner side of the base in a positioning manner, an upper rotating roller is arranged above the lower rotating roller in an attached manner, and two ends of the upper rotating roller are longitudinally and slidably connected with the base through longitudinal elastic reset sliding components. According to the rolling device, the upper rotating roller capable of longitudinally sliding is designed, so that the gap between the upper rotating roller and the lower rotating roller is adjustable, the rolling device can be suitable for rolling base material layers with different thicknesses, and the upper rotating roller is matched with the telescopic spring, so that the base material layers can be compacted and the rolling effect can be ensured when the base materials with different thicknesses are rolled; in addition, a tensioning wheel assembly is designed, under the condition that the upper rotating roller is adjusted up and down, it can be guaranteed that the transmission belt between the belt gear A and the belt gear B is always in a tightened state, and the situation that the upper rotating roller and the lower rotating roller cannot rotate synchronously due to loosening of the transmission belt is avoided.
