Tire making machine

Abstract

A tire forming machine is provided to enable extrusion of raw materials and a winding operation to be performed simultaneously and to achieve a high-quality tire by a precise forming work without using toxic materials such as a releasing agent or an adhesive agent, which simplifies a tire manufacturing process and reduces an overall operation time, thereby increasing the manufacture and preventing environmental pollution while reducing the manufacturing cost. The tire forming machine comprises: an injection cylinder(200) having a built-in injection screw(210) and a heater(201); an extrusion cylinder(100) connected to the injection cylinder(200) via a check valve(220), and having a nozzle(150) rotated by a rotation motor(160), and a nozzle chuck(152) connected to the extrusion cylinder(100) via a bearing(153) and connected to the rotation motor(160) via a nozzle gear(154) and a rotation gear(161); a piston(110) reciprocating vertically inside the extrusion cylinder(100) and installed so as not to rotate; a transfer screw(120) having one end fixedly connected to the piston(110); a transfer nut(130) fitted into the transfer screw(120) and rotated by a driving motor(140); a ball(131) installed between the transfer screw(120) and the transfer nut(130); and a winding roller(300) on which a rubber ribbon(400) is wound after being extruded and formed.

Description

technical field [0001] The present invention relates to a tire building machine that molds raw materials such as rubber into a belt shape and rolls them on a roller to form the basic shape of the tire when manufacturing tires. Specifically, the raw materials that become plastic after heating are adjusted according to the precise stamping speed. , a tire building machine that uses a conveying screw and a piston to extrude through a nozzle, rotate the nozzle according to the curling angle, and simultaneously extrude the raw material and roll it on the forming curling drum. Background technique [0002] For tires with rubber as the main component, although the manufacturing methods are different in details according to the types of tires, the basic methods include: 1. Intermediate molding: After molding the raw materials into a belt shape, roll it on a drum, and make it into the basic shape of a tire. 2. Vulcanization molding.

Problems solved by technology

[0013] As such, the conventional tire manufacturing process separates the molding of the rubber belt 400 from the crimping of the tire, so the process is not only complicated, but the operation time is also lengthened, which not only reduces productivity, but also becomes a factor that increases manufacturing costs.

[0014] In addition, the mold release agent or adhesive remains on the finished product 900, which reduces the quality of the tire. In the coating process of the release agent and adhesive, or the process of tire molding, toxic substances flow out and evaporate, so there is contamination. serious environmental problems
