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.

Embodiment Construction

[0046] Such as figure 1 , the present invention is made of injection cylinder 200 made into a plastic state after heating the raw material, and its accessory device, and maintains the heated state and plastic state of the material and molds these into a rubber belt 210 after extrusion, and a feeding hopper 202 for supplying the raw material The shape is a general shape used when molding rubber products or synthetic resin products.

[0047] Although such an injection cylinder 200 has the advantage of continuous molding, because the rotating material of the injection screw 210 will be squeezed out, it is not only difficult to adjust accurately due to the rolling path formed in a spiral shape along the injection screw 210 and the elasticity of the material. Injection speed and injection volume, and the control response speed is also very slow.

[0048] Therefore, after the present invention accommodates a certain amount of injection material, these extruding cylinders 100 press...

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. [0003] Figure 5 It is a process flow chart of ...
