Abstract

The invention discloses a continuous heating rubber calender, comprising a workbench, a positioning frame, a roller, a heat driving mechanism and an auxiliary cleaning mechanism. The scheme firstly records the interval time of each time when rubber waste exists on the roller, and then formulates a cleaning plan according to the interval time. When the rubber waste is about to be generated, the heat driving mechanism is controlled to preheat in advance. After the preheating is completed, only a small amount of time is needed to temporarily suspend the calendering operation of the equipment, and only the roller is controlled to rotate. During this process, a heat expansion rod drives a deformable wrapping bag to push out a limit block, thereby driving a folding plate to fold, and making the main brush body fit with the roller. Hot air is used to heat clean the surface of the rotating roller through the air outlet to soften the rubber waste on the surface of the roller. At the same time, the auxiliary brush body and the main brush body fully clean the surface of the roller, which can greatly reduce the time required for cleaning the rubber waste, greatly improve the production efficiency and ensure the production quality.
