The invention discloses an automatic tire retreading work head of a tire mounting/demounting machine. The automatic tire retreading work head overcomes the defects that in the prior art, the tire retreading work head is complicated in structure and large in size, and is difficult to solve the problem that tires with low flatness ratios are difficult to demount. The automatic tire retreading work head is characterized in that a left fixing plate, a right fixing plate, a front connecting plate and a bottom plate are welded into a whole so as to form a fixing frame; an arc-shaped guiding slideway is formed in the middle part of the left fixing plate, and an arc-shaped guiding slideway is formed in the middle part of the right fixing plate. The automatic tire retreading work head has the benefits that the problem that tires with low flatness ratios are difficult to demount is solved, and besides, the mounting/demounting limit of a crowbar is avoided, so that the tire prying action can be performed step by step; the tire prying action can be stopped during the whole process at any time, so that the stress situation of a tire is convenient to observe, and adaptive adjustment can be performed; because only one connecting rod is connected with a tire retreading hook, an air cylinder rod bears small stress when moving up and down, and the air cylinder rod can freely move; particularly, the angle of the tire retreading hook is small, and a groove is deep, so that when the tire is hooked by a tire hooking groove, the tire is not liable to drop off; the upward force applied on tires with low flatness ratios, and run-flat tires is small, so that the problems that a conventional tire retreading hook is large in angle and shallow in groove, and a tire is liable to drop off and difficult to hook when a conventional tire retreading hook is used are solved.
