Curtain tube expanding and guiding device This device is composed of 12 umbrella-shaped support rods, which are driven by power to expand and close. Each support rod is equipped with a number of universal rollers, the front end of the support rod is equipped with a special-shaped air nozzle, and the rear part is equipped with a compressed air source distributor. When the curtain fabric tube is opened and introduced into the machine head, the nozzle simultaneously sprays compressed air to assist the traction. The opening and closing position of the expansion guide device can be automatically controlled by computer programming. Clamping and transferring device for the curtain tube. The clamping ring of the device is equipped with a clamping claw that matches the expansion and guiding device of the curtain tube. The clamping claw is driven by a cylinder to clamp and release the fabric, and is driven by a stepping electric motor for radial movement. , The front end of the cloth clamping claw is also provided with an air jet hole, which can assist the cloth clamping work, so that when the cloth clamping is introduced into the machine head, it forms an air film to work smoothly and is guided by the transfer device and positioned correctly. Improve product quality and work efficiency, and reduce labor intensity. For the replacement of the bias tire building machine, this device is two fundamental technological breakthroughs. It enables the front and back of the two important processes of tire building and the upper cord tube to obtain accurate and reliable guarantees from the process equipment.
Tire expansion device The front part of the machine is equipped with a tyre expansion device driven by a cylinder to peel off the shoulders of the green tire before unloading the tire. It replaces the work of the back pressure roller and saves auxiliary time. The pneumatic control system adopts novel pneumatic components, which are both beautiful and reliable, convenient for maintenance and replacement. The operation of the machine adopts an imported PLC microcomputer control system, and the supply status is programmed control, which can accurately control the whole process of tire building process. Different tyres can be programmed at any time. In order to improve the performance of the product, we have adopted an advanced human-machine interface touch screen display device to intuitively control and display the molding working 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. Tyre building, one of the key links in tyre manufacturing, has undergone a process from manual work to mechanical building, and the degree of automation has also been improved step by step.
