Cloth tube expanding device The device consists of 12 umbrella-shaped support rods, which are driven by the power. Each support rod is provided with a number of universal rollers, a special-shaped air nozzle is arranged at the front end of the support rod, and a pressure air source gas distributor is arranged at the rear. When the curtain cylinder is opened and introduced into the head, the nozzle simultaneously ejects compressed air to assist the traction. The position of the expanding device can be automatically controlled by microcomputer programming. Cloth tube clamping and transferring device The clamping ring of the device is provided with clamping claws matched with the curtain drum expanding device. The clamping claws are driven by the cylinder to release the clamping cloth and released, and are driven by the stepper motor to perform radial motion. The front end of the clamp jaws is also provided with a gas injection hole, which can assist the work of cloth clamping and form a gas film when the cloth is introduced into the machine head. The gas film is smoothly operated and is guided by the transmission device and correctly positioned. Improve product quality and ergonomics and reduce labor intensity. For the replacement of skew tire building machines, this device is two fundamental technological breakthroughs. It makes the two important process work of tire molding positive and negative with the upper curtain cylinder, and get accurate and reliable guarantee from the process equipment.
Expanding device The front part of the machine is equipped with a cylinder expansion device driven by the cylinder to peel off the shoulder portion of the blank before unloading the tire. Replace the work of the rear pressure roller, saving the auxiliary time. The pneumatic control system adopts novel pneumatic components, which are both beautiful and reliable, convenient to repair and replace. The operation of the machine adopts the imported PLC microcomputer control system, and the supply status is programming control, which can accurately command and control the whole process of the tire molding process. Different tires can be programmed at any time with different programs. In order to improve product performance, we have adopted an advanced human-machine touch screen display device to intuitively control and display the molding work status. The control system is designed and installed by the company's electromechanical integration. China's tire industry has a history of 65 years, and it has now become a major tire country in the world. Tire forming, one of the key links in tire manufacturing, has undergone a process from manual work to mechanical molding, and the degree of automation has also increased step by step.
