Description

Styropor oscillating cutting apparatus

The present invention relates to a device for cutting a block-type styropole using a high voltage hot wire at a predetermined interval, and in particular, the styropole is moved by a conveyor of a transfer table and is cut at a predetermined interval by hot wires heated at high voltage, but the horizontal direction is changed. As a result, the heating wire is oscillated by repeating a certain section to ensure fast and clean cutting surface during styropole cutting process to prevent product defects, and even styropol with tough physical properties by flame retardant treatment is easy and easy without frequent disconnection of hot wire. The styropole cutting process is possible to improve the overall workability and productivity and the like relates to a styropole oscillating cutting device.

In general, expanded polystyrene (expanded polystyrene) is widely known by various names such as foam polystyrene, styrofoam, foamed styrene, styropor, and sometimes abbreviated as EPS after the English initial. Styropol is a brand name of BASF AG, a German general chemical company, and Styropol is a thermal insulation material name of Dow Chemical Company of the United States, and is widely used in Korea as Styropol or Styrofoam.

Polystyrene is a widely used plastic. It is a polymer of styrene. It is a colorless and transparent thermoplastic material. It becomes a viscous liquid when it is soft at 100 ° C or higher and reaches 185 ° C. It is strong in acid, alkali, oil, alcohol, etc. Styropol, a foamed polystyrene having a polystyrene resin, is a foamed product in which hydrocarbon gas, such as pentane or butane, is injected into the polystyrene resin and then inflated with steam, and 98% of the volume is air and the remaining 2% is a resin.

In the manufacturing process, a blowing agent such as pentane and butane gas is injected into styrene, polymerized with water, and heated until it reaches a predetermined molecular weight. Subsequently, the beads, which are spherical particles of the expanded polystyrene obtained, are washed and dried, and the waste water is treated and sorted to obtain a finished product.

Styropol is white and light and has excellent water resistance, insulation, soundproofing and buffering properties. It is mainly used for cups, bowls, plates, shell-shaped containers, meat packaging, egg packaging, electronics and other fragile products. It is widely used as a packing material for the transportation of goods, as a building material with wood grain pattern, as a decorative furniture, as well as as a marine product box. In addition, it is also used as a wall material of a meat freezing warehouse, an exterior of a freezing pipe, a wall or ceiling material of a prefabricated house, a stage device of a television, or an artificial snow.

As the use of Styropol is widely used and decorated, such as insulation of buildings, interior and exterior ornaments, stage props of broadcasting stations, etc., various shapes and shapes can be obtained, and more rapid and detailed cutting is possible, and nowadays Various products are being provided according to the preference of Styropol products having improved contrast, strength, and durability.

As described above, the manufactured styropol block is cut and supplied in size and thickness according to the intended use, and various apparatuses and mechanisms for cutting the styropol block to a predetermined thickness using high voltage hot wire for cutting the styrofoam block. Are being used.

Among them, a brief configuration of the Schiropol cutter (not shown) of Utility Model Registration Application No. 1994-17879, filed in Korea, is as follows.

Schiropole can be cut by tightening the hot wire by installing chain gears on both sides of the machine body and rotating them by a drive motor that puts the chains together, and installing a shaft with an insulated threaded rod on both sides of the machine body center. In the cutter so that the outer side of the shaft rod is installed in the state in which the fixed rod is installed in the spring standing up and the installation bar to the outside of the shaft rod is installed so that the air cylinder to supply one air supply rod and air, the heating wire is It is composed of one side connected to the end of the air cylinder at the spring and the other side in intimate contact with the thread of the shaft.

According to the above configuration, both ends are connected to each other during cutting of the swivel pole, and the tension is maintained by the spring and the air cylinder.

However, such a conventional styropol cutting machine is possible to cut the normal styropol,

First, Styropol is coated with a flame retardant to increase the flame retardancy and durability, etc. Styropol produced by using various additives for increasing the durability is difficult during the cutting process due to the overall physical properties and delivered to the hot wire during cutting As the load increases, the overall cost rises due to the increase of maintenance costs such as frequent disconnection of hot wires and maintenance.

Secondly, the styropol produced generally has an overall volume, so that styropol blocks are usually produced and temporarily stored in factories, etc., before leaving the factory.In this case, various contaminants are trapped in the space between the particles of styropol or transported on the surface. When cutting the styropol, contaminants and the like are in contact with the heating wire, so that the cutting surface is irregular and roughly formed, thereby degrading workability,

Third, since the styropol is cut while the contact portion is melted upon contact with the heating wire heated by electricity, there is a problem in that the productivity of cutting is limited and the overall productivity is limited.

Accordingly, the present invention has been made to solve the fundamental problems of the prior art, the purpose of which is to cut at set intervals by hot wires heated to high voltage while the styropole is moved by the conveyor of the transfer table is constant along the horizontal direction By repeating the section, the heating wire is configured to oscillate to ensure fast and clean cutting surface during styropol cutting process, to prevent product defects, and even to styropol having tough physical properties by flame retardant treatment without severity of hot wire.
