The invention relates to automatic rubber cutting equipment and an automatic rubber cutting method. The automatic rubber cutting equipment comprises a bottom plate, a mounting frame, a rubber cuttingdevice and a conveying device, wherein the mounting frame is arranged on the bottom plate, and the mounting frame is of an inverted-U-shaped structure; a sliding groove is formed in the lower end of the mounting frame; the rubber cutting device is arranged in the sliding groove; the conveying device is arranged at the lower end of the rubber cutting device, and the conveying device is arranged onthe bottom plate; and the rubber cutting device comprises a base plate, a fixed knife rest, an adjusting knife rest, an adjusting frame, an adjusting gear, a mounting plate, an adjusting motor, a blade, a scraping frame, a buffer spring, a connecting frame and a rubber cutting air cylinder. By virtue of the automatic rubber cutting equipment, the problems that the adjustability is poor in the rubber cutting process, the rubber is easy to adhere to the blade, manual cleaning is needed, the potential safety hazard is large, and the rubber position is not easy to control and the like can be solved; and the automatic rubber cutting function can be realized, and the advantages are realized that adjustment is flexible, the rubber is not easy to adhere to the blade, manual cleaning of the blade is not needed, the safety is high, the position of the rubber is not easy to change, and the like.
