Embodiment Construction

[0011] The cutting process of the engineering radial tire carcass cord / belt combined cutting machine of the present invention is based on the belt layer cutting production line and carcass cord cutting production line of small and medium-sized engineering radial tires. The belts are cut on a cutting machine.

[0012] The specific cutting process of the engineering radial tire carcass cord / belt combined cutting machine of the present invention is as follows:

[0013] 1. Belt production

[0014] Decoupling After the material roll is detached, it passes through the traction device for fixed-length delivery and then cuts. After cutting, it is transferred to the belt joint device through the conveyor belt for automatic jointing. After the device is pasting the film and wrapping the edge, it is transferred to the coiling device for coiling.

[0015] The specific working process is:

[0016] A. Install the calendered large roll steel cord to the unwinding station of the cutting ma...

Abstract

The invention relates to a combined body ply / belt layer cutting process for engineering radial tire, which belongs to the field of tire manufacture technology. The process comprises the following steps: guiding a guide roller, feeding cloth at fixed length by a traction device, cutting by a cutting machine, transferring to a belt layer jointing device by a conveying belt to carry out automatic jointing, storing the jointed belt layer and transferring to an automatic rubber sheet bonding device by a conveying belt to bond a rubber sheet and wrap the edges, and transferring to a coiling device to coil the belt layer; and guiding a guide roller, feeding cloth at fixed length by a traction device, cutting by the same cutting machine, transferring to a body ply jointing device by a conveying belt to carry out automatic jointing, storing the jointed body ply and transferring to an automatic rubber sheet bonding device by a conveying belt to bond a rubber sheet and wrap the edges, and transferring to a coiling device to coil the body ply. The process has the advantages of reduced equipment investment and ensured cutting accuracy and process requirement of the body ply and the belt layer.

Description

technical field [0001] The invention belongs to the technical field of tire manufacture, in particular to a process method for cutting a carcass cord and a belt layer of a giant engineering radial tire in the form of a carcass cord / belt layer combination. Background technique [0002] As we all know, tires used for engineering vehicles are referred to as engineering tires. Domestic and foreign manufacturers are mainly engaged in engineering tires with bias structure. In recent years, they have developed and produced all-steel engineering radial tires. For small OTR tires, the carcass ply and belt layers used to produce tires of this specification are all produced by independent conventional cutting machines. However, for the carcass cord (maximum width 5.5 meters, thickness 1.5-8mm) and belt layer (maximum width 1400mm, thickness 1.5-8mm) of giant OTR tires over 49 inches, there is no mature cutting process in China. The production cycle of a giant single tire is long (3-4 ...
