Green Case Preheater {DEVICE OF PREHEATING GREEN CASE}

The present invention relates to a green case preheating apparatus, and more particularly, to a green case preheating apparatus for preheating the green case and maintaining preheated heat in the process of transferring the green tires formed in the molding machine to the vulcanizer. .

As is well known, finished tires are a refining process in which raw materials, ie natural rubber, synthetic rubber and chemicals, are mixed to produce compounds with specific physical properties, extrusion / rolling / cutting processes to produce the compound in semi-finished form of a sheet, It is manufactured through a molding process of forming semi-finished products to make a green case, and a vulcanization process of vulcanizing the green case to produce a finished product tie.

However, the green case formed in the molding machine is placed in various types of storage shelves and stored at room temperature before being sent to the vulcanizer for the vulcanization process.

As such, since the green case is left at room temperature for a long time, it is required to raise the room temperature from the room temperature to the vulcanization temperature in order to cure the tire in the vulcanizer.

Generally, the vulcanizer is heated from the outside to the inside by using a mold or bladder to complete the vulcanization process in a short time, but the temperature outside the surface of the green case is short-term because the green case is mainly composed of rubber with low thermal conductivity. While rising inside, the temperature inside the thick tread portion or bead portion gradually rises.

Therefore, in order to make all parts of the green case vulcanize by heating with only the vulcanizer, it takes several tens of minutes, which in turn lowers the productivity of the finished tire.

An object of the present invention for solving the above problems is to preheat the green case in the process of being molded in the molding machine and transferred to the vulcanizer, and to maintain the preheating temperature by using the waste heat source discarded in the vulcanizer for the productivity of the finished tire It is to provide a green case preheating device to improve the.

The green case preheating device of the present invention for achieving the above object comprises a plurality of preheating rooms for continuously preheating the green case while the green case molded in the molding machine is suspended on the fixed chuck and transported to the vulcanizer. A first preheating room provided with preheating means for primary heating of the green tire on at least one side of a wall surface constituting a moving passage of the case; And a second preheat room for maintaining primary heated heat of the green case transferred from the first preheat room using the waste heat source recovered from the vulcanizer.

 The preheating means may include a first high frequency induction heater installed at one wall of the passageway of the first preheating room; And a halogen lamp installed at the other side of the passage of the first preheating room so as to face the first high frequency induction heater and the green tire being transported therebetween.

 The first high frequency induction heater may be installed to face one side tread portion of the green case.

 The first high frequency induction heater may be fixedly transportable from one side wall of the passage toward the tread surface of the green case.

 The first high frequency induction heater may have a curvature corresponding to the circumference of the green case and may be formed in a semicircular shape.

 The halogen lamps are preferably installed to correspond to the shoulder parts on both sides of the green case.

 The halogen lamps are preferably fixed so as to be transportable from the tile side wall of the passage toward the shoulder portion of the green case.

 The first high frequency induction heater may be formed in a semicircular shape with a curvature corresponding to the circumference of the green case.

 The preheating means may comprise a second high frequency induction heater provided at the end of the fixing chuck so as to be located at the hollow center in the green case.

 In the first preheating room, a passage forms at least one row, and the passage may be formed by forming a plurality of pairs of a first high frequency induction heater and a halogen lamp.

According to the green case preheating device of the present invention, the green case which is molded in the molding machine and transferred to the vulcanizer is heated in the first preheating room to be preheated, and then the preheating temperature can be maintained using the waste heat source in the second preheating room. This has the effect of improving the productivity of the finished tire.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.
