Belt ply drum host and drive method thereof

Abstract

The invention provides a belt ply drum host and a drive method thereof, and the belt ply drum host of a forming machine for preparing a tire, belongs to a machinery manufacturing field. Aiming at a problem of fitness precision of a belt ply in a fitting process, the belt ply host is provided for raising radially-stretching precision and implementing multi-point control in a belt play drum one-step fitting technology process, wherein a second driving mechanism for supplying power for radially moving the belt ply drum, and a plurality of synchronization assemblies for implementing synchronous and radial movement of the belt ply drum, and the plurality of synchronization assemblies are circumferentially and fixedly matched in a certain distance, and are arranged in a same circumference surface. Precision requirement in a belt ply material fitness technology is satisfied.

Description

technical field [0001] The invention relates to a belt drum host of a forming machine for preparing rubber tires and a driving method thereof, belonging to the field of rubber machinery manufacturing. Background technique [0002] In the manufacturing process of rubber tires, the uniformity of belt layer material bonding is one of the most direct and critical factors affecting the safe use of tires. The existing semi-steel tire building machine usually adopts that several drive cylinders are installed on the side plate of the belt drum main body, and are directly connected with the belt drum through the drive shaft, and the driving force is directly transmitted to the belt drum. The drum tiles of the belt drum realize the radial telescopic movement of the belt drum and complete the lamination of the composite layer of the belt material. [0003] The belt drum host equipment of the prior art usually also has the following main defects: [0004] 1. If a pneumatic actuator is...

AI Technical Summary

Problems solved by technology

[0004] 1. If a pneumatic actuator is used, it is very difficult to precisely control the driving force. If the driving force is too small, it will easily cause the belt material to slip, and if the clamping force is too large, it will easily cause the belt material to deform. Directly affect the uniformity of the composite layer structure of the belt layer material

[0005] 2. Pneumatic drive is used to drive the actuator. During the driving process, only two position points can be controlled, and the control accuracy of the middle point in the lamination process of belt layer materials cannot be guaranteed. Bubbles are likely to be generated during the lamination process and affect the to tire build quality
