Step six: as shown in fig. 11, the rubber ring plate material 13 is pressure-rolled by a fixed round roll 71, a round roll core 14, and a forming tension cloth 72, left for a while, and then set. The second ball screw component 83 drives the limiting hook 81 to move forward, and drives the round roller core 14 with the rubber ring plate raw material 13 to move forward for a certain distance, and then the rubber ring plate raw material 13 is wound on the round roller core 14.

Step seven: as shown in fig. 12, the in-out cylinder 82 drives the limiting hook 81 to move upward to straighten the forming tension cloth 72, and the round roller core 14 with the rubber ring is ejected out to the guide rail 9 by the straightening thrust of the forming tension cloth 72.

Step eight: the rubber ring-equipped round roller core 14 slides down along the guide rail 9 to the bottom of the guide rail 9, and the rubber ring-equipped round roller core 14 is cooled by air blowing through a plurality of air nozzles 102.

Step nine: the conveying hook 123 is driven by the ball screw assembly three 121 and the conveying cylinder 122 to descend, so that the round roller core 14 is hooked between the clamping plate 105 and the rubber buffer strip 103 and clamped by the clamping cylinder 104.

Step ten: the rodless cylinder 111 drives the pneumatic finger 113 to move right, the pneumatic finger 113 clamps the end part of the round roller core 14 which is not wound with the rubber ring plate raw material 13, then the rodless cylinder 111 moves left, the round roller core 14 is drawn out from the inside of the rubber ring due to the action of friction force, and after the round roller core is completely drawn out, the rubber ring finished product is blanked. The rodless cylinder 11 then moves in reverse direction to the right to the initial position (i.e., step one is repeated, with this cycle).

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
