[0002] The reverse wrapping action of a tire forming machine is a key point in the tire forming process. Currently, the existing tire forming machines can be divided into a bladder drum forming machine and a mechanical drum forming machine according to the reverse wrapping form. The reverse wrapping action of the bladder drum forming machine relies on the bladder inflation action to assist components such as the tire sidewall carcass to open from a cylindrical shape to a radial shape and then adhere to the tire side, forming the tire sidewall part. As a consumable tooling accessory in the tire production industry, the usage amount of the forming bladder increases with the growth of the tire production quantity.

[0003] In the process of manufacturing the existing tire forming machine bladder, it is divided into three processes: rubber cylinder fitting, bladder assembly, and vulcanization. The process of fitting the rubber cylinder (rubber sheet plus skeleton cord fabric) is completed on a rotating drum. After completion, a plastic sheet (or called PE paper) still remains at the bottom of the innermost rubber sheet of the rubber cylinder. This process only completes the production of a cylindrical bladder body. After that, this cylinder is removed from the rotating drum, the bladder body is folded in the external space, and then transferred to the bladder assembly drum, and the bladder assembly procedure is completed with the front part of the bladder on the assembly drum. Finally, the external accessory parts of the bladder are attached, and then the operation of winding the water wrapping cloth outside the bladder is completed, thus completing all the operations of bladder fitting and assembly.

The main drum device 100 is arranged on the side of the rotating platform 500 close to the first inside - out and outside - in device 300, and the second inside - out and outside - in device 400 is arranged on the side of the rotating platform 500 close to the auxiliary drum device 200; the first inside - out and outside - in device 300 can cooperate with the main drum device 100 to complete the inside - out and outside - in action of the main drum material, and the second inside - out and outside - in device 400 can cooperate with the auxiliary drum device 200 to complete the inside - out and outside - in action of the auxiliary drum material.

[0027] That is, a one-step forming machine for tire capsules provided by an embodiment of the present invention relatively arranges a first right and left wrapping device 300 and an auxiliary drum device 200 on both sides of a rotating platform 500. After the right and left wrapping operation is completed, the positions of the auxiliary drum device 200 and the first right and left wrapping device 300 can be swapped by rotating the rotating platform 500, so as to move the auxiliary drum device 200 to be docked with the main drum device 100, enabling the rubber cylinders on the main drum device 100 and the auxiliary drum device 200 to be docked without being moved, thereby completing the docking of the workpieces on the main drum device 100 and the workpieces on the auxiliary drum device 200, solving the technical problems in the prior art that the rubber cylinder of the capsule main body is transferred between different workstations, which easily causes process deviations such as positioning or stretching and workpiece contamination, improving the production efficiency of tire capsules and ensuring the product qualification rate of tire capsules.

[0028] Specifically, the base of the rotating platform 500 is cylindrical. A motor and a transmission gear can be arranged at the bottom of the rotating platform 500, so that the rotating platform 500 rotates around its axis. A transmission box is installed above the rotating platform 500. The transmission box is provided with a motor and a gear set inside. Two output shafts of the gear set are respectively connected to the first right and left wrapping device 300 and the auxiliary drum device 200 installed on the transmission box to drive them to operate. The main drum device 100 and the second right and left wrapping device 400 are respectively arranged on both sides of the rotating platform 500, so that after the rotating platform 500 rotates, the main drum device 100 can be docked with the auxiliary drum device 200. In this embodiment, the main drum device 100 is used to bond the main body film and the cord fabric to form a main body cord fabric coated cylinder. The auxiliary drum device 200 is used to bond the auxiliary drum film and the cord fabric to form an auxiliary drum cord fabric coated cylinder. The two right and left wrapping devices are used to perform right wrapping and left wrapping operations on the main body cord fabric coated cylinder and the auxiliary drum cord fabric coated cylinder in sequence.

[0029] Further, the main drum device 100 includes a main drum guide rail 110, a main drum machine case 120, and a main rotating drum 140; the main drum guide rail 110 is arranged along the extending direction of the main drum device 100 towards the rotating platform 500, the main drum machine case 120 is slidably arranged on the main drum guide rail 110, the main rotating drum 140 is sleeved on a main drum shaft 130 arranged in the horizontal direction, and the main drum shaft 130 is in transmission connection with the main drum machine case 120 to drive the main rotating drum 140 to rotate around the main drum shaft 130.

[0030] Specifically, the main drum guide rail 110 is arranged horizontally on one side of the rotating platform 500, and its extending direction faces the first positive and negative wrapping device 300 on the rotating platform 500. The main drum chassis 120 is slidably arranged on the main drum guide rail 110. A motor and a transmission mechanism are arranged in the main drum chassis 120, and the transmission mechanism drives the connection between the motor and the main drum shaft 130. In this embodiment, the transmission mechanism can be set as a gear set to drive the main drum shaft 130 to rotate, and the main drum chassis 120 uses a lead screw mechanism as power to achieve sliding on the main drum guide rail 110. The main drum shaft 130 is key-connected to the main rotating drum 140, so that the main drum shaft 130 can drive the main rotating drum 140 to rotate. By arranging the main drum chassis 120 and the main rotating drum 140 to be slidably arranged on the main drum guide rail 110, the main rotating drum 140 can slide away from or close to the first positive and negative wrapping device 300. After the positive and negative wrapping action is completed, the main rotating drum 140 can be slid away from the first positive and negative wrapping device 300. When the rotating platform 500 rotates the auxiliary drum device 200 to the original position of the first positive and negative wrapping device 300, the main rotating drum 140 is then slid close to the auxiliary drum device 200 to facilitate the docking of the two.

[0031] Preferably, the tire capsule one-step forming machine further includes a main drum feeding device 600. The main drum feeding device 600 includes a main drum feeding rack, a first material conveying mechanism, and a first material unwinding mechanism.

At the same time, the first material diverting mechanism in this embodiment also includes a mechanism including a winding function. While the material is diverted, the PE paper or padding cloth covering the material is synchronously wound. After the material is used up, the remaining PE paper or padding cloth on the workstation is removed with the mechanism and replaced with a new material storage mechanism. In this embodiment, the first material diverting mechanism is provided with three to divert materials of different materials respectively. The first material conveying mechanism is provided with a frame, an active roller, a driven roller, a driving motor and a conveying belt, so as to convey the film and curtain fabric diverted by the first material diverting mechanism to the main drum feeding rack.
