Automatic oil spraying method and device for diagonal tyre forming machine

Abstract

The invention discloses an automatic oil spraying method and device for a diagonal tyre forming machine. A craft punch and a back pressing device of the tyre forming machine are respectively provided with two groups of automatic oil nozzles finishing automatic oil spraying in twice; the first group of oil nozzles are split or integrated along with the craft punch, a lifting cylinder vertically moves, and the oil nozzles are automatically controlled to spray oil when the lifting cylinder lifts to a required position; and the second group of oil nozzles advance or retreat, rotate and are split or integrated along with a back pressing roller, and the oil nozzles are automatically controlled to spray oil when the back pressing roller rolls to a required oil spraying position, so that the automatic oil spray of the diagonal tyre forming machine is finished. Main working parts of the forming machine, a forming drum and the back pressing device are respectively provided with a group of following oil nozzles, the oil nozzles are automatically controlled to spray oil at the optimal positions through controlling an electromagnetic valve, and the oil spraying amount can be effectively controlled. Therefore, by using the automatic oil spraying method and device, defects of the traditional manual oil spraying way can be completely overcome, and the product quality is stably improved.

Description

technical field [0001] The invention relates to a tire processing method and device, in particular to a method and device for automatic oil injection of a bias tire building machine. Background technique [0002] The tire building process is to put the cord tube into the building drum (generally three layers), and after each layer of cord is put in, it will rely on the advance and retreat, separation and closing, and rotation of the rear pressure roller to realize the reverse wrapping of the steel wire, the front wrapping of the cord tube, and the cord Stepping actions such as stripping the barrel and the forming drum, pressing the tread, etc. Among them, gasoline needs to be injected when the cord tube is wrapped, and the cord tube is separated from the forming drum. The fuel injection method of the traditional molding machine is to manually hold the fuel injection ball, and squeeze the fuel injection ball with your hand to make the gasoline spray out from the pipe inserte...

Problems solved by technology

The fuel injection method of the traditional molding machine is to manually hold the fuel injection ball, and squeeze the fuel injection ball with your hand to make the gasoline spray out from the pipe inserted into the fuel injection ball. This traditional method has the following disadvantages: 1) Frequent manual operation ;2) The fuel injection position is inaccurate, 3) A large amount of gasoline is wasted; 4) Excessive gasoline dissolves the carcass rubber to form a glue that is thrown onto the equipment and human body with the rotation of the forming drum, causing serious pollution
