Multifunctional calendaring machine for tire cord

Abstract

The invention provides a multifunctional calendaring machine for a tire cord. Traction roll frames extending out forwards are arranged at the upper ends of the front sides of a left machine frame and a right machine frame respectively; an upper traction roll and a lower traction roll are mounted between the upper ends and the lower ends of the traction roll frames on the left side and the right side respectively; the middle of the front side of each of the traction roll frames on the left and right sides extends out forwards to form a punching roller mounting plate; strip-shaped through holes are formed in the punching roller mounting plates; screw rod seats are arranged on the inner sides of the front ends of the punching roller mounting plates; screw rods penetrate through the screw rod seats and are connected with punching roller bearing seats; slide blocks are further arranged on the punching roller bearing seats, extend into the strip-shaped through holes and are glidingly connected with the strip-shaped through holes; a roller shaft at two ends of a punching roller is mounted in bearings in the punching roller bearing seats on the left side and the right side in a sleeving manner respectively; punching needle assemblies are distributed on the surface of the punching roller; each punching needle assembly comprises a punching needle, a base and a screw rod; the punching needle assemblies are connected to the surface of the punching roller through the screw rods. Punching and exhausting are finished while a tire cord layer is produced.

Description

technical field [0001] The invention relates to a multifunctional tire cord calendering machine. Background technique [0002] The ply is the skeleton of the pneumatic tire, which is made of several layers of hanging rubber plies, and it bears most of the load acting on the tire. [0003] For ordinary tires, the number of ply layers is generally an even number such as 4-18 layers. The number of layers of radial tires is odd, such as 1-5 layers. Tire plies are produced by a ply calender. The calender includes a left frame and a right frame, a roller is installed between the left frame and the right frame, and the surface of the cord fabric coming out of the calender is coated with cord fabric. In order to bond the multi-layer curtain fabrics, the upper ends of the front sides of the left frame and the right frame are respectively provided with forwardly extending traction roller frames, and upper traction rollers are respectively installed between the upper and lower ends ...
