◐ Equipment structure and working principle

Ftc-1422 truck tire winding machine consists of five parts, as shown in the figure


1 winding head  2 winding base  3 main engine  4 base  5 material storage device

1.1 winding head

1) function: the rubber strip extruded by the extruder is rolled into the shape required by the process to ensure the consistency and uniformity of the rubber strip shape. At the same time, the rubber strip attached to the tire surface is pressed to ensure its firm bond with the tire body and remove the bubbles at the joint, which is very important for the quality of winding.

2) structure: guide device, rolling device, roller, side roller, guide rail, etc


1 guide device  2 calender device  3 roller  4 side roller  5 guide rail

1.2 winding base

1) function: make the winding head move back and forth, cooperate with the main machine to do tread copying movement, and can rotate to make the winding head perpendicular to the bonding surface.

2) mechanism composition: winding base, rotating device, feed device, etc


1 winding base  2 rotating device  3 feeding device

1.3 the host

1) function: make the tires move from side to side, cooperate with the winding base to make tread copying movement, and inflate the tires.

2) mechanism composition: driving device, expansion drum, column, translation device, etc


1 driving device 2 expansion drum 3 column 4 translation device
