[0024] Refer to Figures 1-5 , a forming drum for tire forming, including a support frame 1, a drum body 2 and a collection tank 3. The above support frame 1 and drum body 2 are both mature products of the prior art, and there are other devices for forming the forming drum for tire forming that are not drawn in this solution. This solution does not describe the components of the mature part, but only describes the part where the problem is proposed and improved.

[0025] The collection tank 3 is provided with a mounting plate 7, the support frame 1 is provided with an installation groove 5, the mounting plate 7 is provided with an upper top groove 8, a positioning block 10 is provided in the upper top groove 8 through an upper top mechanism, the support frame 1 is provided with a positioning hole, two pulleys 13 are rotatably provided on the mounting plate 7, and the two pulleys 13 are connected by a belt. The upper pulley 13 is connected to the drum body 2 through a transmission mechanism. The wiping shaft 14 is provided on the mounting plate 7 through a rotating hole, the wiping shaft 14 is connected to the lower pulley 13 through an insertion mechanism, a wiping cloth 4 is provided on the wiping shaft 14, a movable groove 17 is provided inside the wiping shaft 14, a sliding rod 18 is provided in the movable groove 17, and a movable frame 20 is slidably sleeved on the sliding rod 18 through an elastic mechanism. The inner wall of the rotating hole on the fixing frame 11 is provided with an annular groove corresponding to the movable frame 20.

[0026] The upper top mechanism includes a vertical spring 9 provided in the upper top groove 8. The two ends of the vertical spring 9 are elastically connected to the outer wall of the positioning block 10 and the inner bottom wall of the upper top groove 8 respectively. The vertical spring 9 realizes the upper top of the positioning block 10, and the positioning block 10 can be pushed into the positioning hole to realize the stable installation of the mounting plate 7 and the support frame 1.

[0027] The transmission mechanism includes a transmission gear 12 provided on the fixing frame 11 and connected to the upper pulley 13, and a driving gear 6 meshing with the transmission gear 12 is provided on the rotating shaft of the drum body 2. The above driving gear 6 and transmission gear 12 realize power transmission, and when the drum body 2 rotates, the synchronous rotation of the wiping shaft 14 can be finally realized.

[0028] The insertion mechanism includes an insertion block 16 installed on the wiping shaft 14, and a jack 15 corresponding to the insertion block 16 is provided on the pulley 13 below. The vertical cross-sectional view of the jack 15 and the insertion block 16 is a regular hexagon. When the wiping shaft 14 passes through the rotating hole and the insertion block 16 enters the jack 15, the rotation of the lower pulley 13 can drive the wiping shaft 14 to rotate synchronously.

[0029] The elastic mechanism includes a horizontal spring 19 sleeved outside the sliding rod 18, and both ends of the horizontal spring 19 are elastically connected to the inner wall of the movable groove 17 and the outer wall of the movable frame 20.
