Description

Apparatus for Preparing a Synthetic Resin Sheet}

The present invention relates to a synthetic resin sheet molding apparatus. More specifically, the present invention relates to a synthetic resin sheet molding apparatus in which a heat generating member for fusion-splicing a waterproof synthetic resin wide sheet, a synthetic resin tube, or the like is fused.

Conventionally, in the case of landfill sheets, sheets are spread over a large area and overlapped with each other to apply coal tar black liquid, or to use adhesive tape or the like, but they are not semi-permanent functions. Becomes In the case of the leachate drain pipe, a heat fusion butt method, a heat fusion socket method, a sheet fusion method, and the like are used to connect a predetermined length to each other.

In the case of double sheet fusion method, in the case of Korea Utility Model Registration No. 0124493, after injection molding the sheet resin plate into the landing space and the thermal balance in one piece, after combining the mesh coils manufactured separately according to the size of the landing space and the thermal balance, And a resin pipe fusion bonding sheet manufactured by connecting a connection terminal for supplying power.

The above method has been a problem of injection molding processes such as injection molding and mesh bonding when the synthetic resin tube diameter is large diameter (600 mm or more) in injection molding a fixed landing space and a thermal balance in one piece .

In the case of the sheet forming method and apparatus for fusion welding of Korean Patent No. 10-0288133 (00.02.05. Registered), a perforated network and a resin that extends holes while drilling a metal plate, which is a heating material, as a method of forming a heating material in a plate-like sheet A method and apparatus for forming the perforated network and the resin plate into an integrated sheet by passing a plate through a pair of forming rollers heated to 200 ° C. with uneven surface are provided.

Republic of Korea Utility Model Registration No. 20-0203746 (01.02.05. Registration) is to form a wavy pattern in forming the protrusions and grooves on one surface of the sheet plate to neutralize the molten lath (heating material) on the surface in one step The problem of the diameter length due to the diameter can be solved through the process, but the multi-stage process of the las defect process is required and more importantly, the metal mesh, lath, etc., which are heat generating materials in the heat fusion method, are deposited on the surface of the resin plate. When the heat source is supplied, the surface resin layer melts easily and the synthetic resin heating temperature is 200 to 230 ° C, whereas the melting point is 120 ° C, and the surface melts easily and the heating material such as metal mesh or lath separates and comes into contact with oxygen. Fire, or ignition, is a factor. In addition, there is a problem that causes economic losses such as waste of resources, severity of soil pollution, etc. due to leakage due to the normal fusion splicing is not made due to the separation of the heating material is not even heat conduction.

Republic of Korea Patent Application Publication No. 2003-0040708 is heated by hot air at a temperature of 100 ~ 200 ℃ on the resin plate top plate, and laminating the sheet to cover the metal mesh bonding process and the heating and maintaining at a temperature of 100 ℃ ~ 200 ℃ on the upper side The molding method and structure of a resin pipe fusion splicing sheet formed through a coalescing process are disclosed. The method has disadvantages such as the inconvenience of having to go through a number of processes and the cost burden according to the process, and a long length of the pipe makes it difficult to manufacture and safety construction is impossible.

In order to solve the above problems, an object of the present invention is to provide a synthetic resin sheet molding apparatus for easily inserting the heating member into the synthetic resin sheet.
