Description

TECHNICAL FIELD [0001] The present invention relates to a device for manufacturing a reinforced plastic sheet,

The present invention relates to an apparatus for manufacturing a reinforced plastic sheet for manufacturing a synthetic resin sheet with a built-in mesh, and more particularly, to a method for manufacturing a synthetic resin sheet having a mesh, Which can easily reduce the unit cost of the reinforced plastic sheet.

Reinforced plastic refers to a resin molding such as an unsaturated polyester or an epoxy resin added with a reinforcing material. Glass fiber is the most used as the reinforcement material, and other materials such as hemp, nylon, and polyester fiber are embedded in the resin molding. It is used for automobiles, boats, safety helmets, pipes, laminates and so on.

A technique for manufacturing such a reinforcing plastic in the form of a plate has been filed by the Japanese Patent Application No. 10-2013-0005969, which is a process for producing a primary resin-powder mixture by mixing a melted thermoplastic synthetic resin with a powder in the form of a solid powder ; Molding the primary resin-powder mixed workpiece to produce a resin-powder mixed plate in the form of a flat plate; Wherein the synthetic resin fibers are pressed together by applying heat to the synthetic resin fibers in the state that the synthetic resin fibers in the form of felt or nonwoven fabric are superimposed on the resin- ; .

However, in the conventional technology as described above, instead of fabricating a plate body in an extruder while inserting a fiber mesh between two plate bodies, a method of repeatedly heating and pressing a fiber mesh after forming a plate body by an extruder is repeated There is a disadvantage in that the productivity is lowered and the unit cost of the product can be increased because of the consumption of the heat amount for heating and pressing the already formed plate body and the fiber mesh.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a method of manufacturing a polypropylene sheet by injecting a plurality of platelets made of synthetic resin into an extruder, The present invention provides a method for manufacturing a reinforced plastic sheet, which can produce a synthetic resin plate having a fiber mesh or the like embedded therein in one process, thereby improving productivity and reducing energy costs.

In order to achieve the above object, the present invention provides an apparatus for manufacturing a reinforced plastic sheet comprising a plurality of platelike synthetic resin materials extruded by a plurality of extruders, A plate-like member guide member is provided at the tip end portion of each of the plurality of extruders, respectively, and a guide for converting the direction of the mesh supplied in the lateral direction between the plate-like member guide member and the plate- And a conveying roller for conveying a composite plate-like material in which a plate, a mesh, and a plate-like body are laminated is provided between the plate-like member guide member and the plate- And cooling means for cooling the composite plate conveyed by the conveying roller is provided on the conveying roll, The present invention also provides an apparatus for manufacturing a reinforced plastic sheet, which is provided on the outlet side of the reinforcing plastic sheet.

In the apparatus for producing a reinforced plastic sheet according to the present invention, a plurality of platelets made of synthetic resin are injected by an extruder, and a fiber mesh or the like is supplied between the two platelets to form a mesh between the platelets It is possible to produce a synthetic resin plate having a fiber mesh or the like as a single process, thereby improving the productivity and reducing the energy cost, thereby easily reducing the unit cost of the product.

2 is an enlarged cross-sectional view of part A of Fig.
Fig. 3 is a plan view showing the inside of the plate-like member guide member and the plate-like member guide member for explaining the supply of the mesh corresponding to A in Fig.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 to 3 are views showing an apparatus for producing a reinforced plastic sheet according to the present invention. The apparatus for producing a reinforced plastic sheet is composed of a plurality of platelets 2 made of a synthetic resin material extruded by a plurality of extruders 1 In the present invention, the mesh 3 is directly supplied between the two sheet-like objects 2 discharged from the extruder 1. In this embodiment, two extruders are shown It is possible to manufacture the composite plate material 4 obtained by laminating the plate material 2, the mesh 3 and the plate material 2 as described below even with a plurality of extruders.

In the present invention, a die 11 for expanding and discharging the fluid synthetic resin heated in the extruder 1 to the plate body 2 is provided at the distal end of each of the plurality of extruders 1, Plate guide members 12 are respectively provided so that the flat plate-shaped bodies 2 are smoothly conveyed under pressure in the plate-shaped guide members 12.

Guide rollers 13 for converting the direction of movement of the mesh 4 supplied in the lateral direction between the plate-like member guide member 12 and the plate-like member guide member 12 are disposed between the plate- And between the upper body guide members 12 in a rotatable and oblique direction.

3, the guide rollers 13 are arranged diagonally. Therefore, the mesh 4 fed in the lateral direction between the plate-like object guide member 12 and the plate-like member guide member 12 is divided into two plates And can be transferred between the upper bodies 2 in parallel with the lower body.

A plurality of conveying rollers 14 for conveying the composite plate material 4 on which the plate material 2 and the mesh 3 and the plate material 2 are laminated are conveyed to the exit side of the plate material guide member 12 And a cooling means 15 for cooling the composite plate member 4 to be conveyed by the conveying roller 14 is provided at the exit side of the conveying roller 14. [

Of course, the cooling means is provided with a plurality of cooling rollers. As in the prior art, cooling water is made to flow inside the cooling rollers to cool the composite platelet 4 with the cooling rollers themselves, or use nozzles to jet cooling air or cooling water And the cooling device is capable of cooling the composite plate material 4 moving by a plurality of cooling rollers. Such a cooling device uses the conventional configuration as it is, and cuts the composite plate material passed through the cooling device to a constant size Or wound with a winding machine.

A guide nozzle 12a for guiding the plate member 2 is provided between the conveying rollers 13 disposed on the upper and lower sides of the plate guide member 12, On the outlet side, there can be provided a support roller 16 or a wrinkle prevention roller of a textile machine which prevents the mesh 3 from being corrugated.

The apparatus for manufacturing a reinforced plastic sheet according to the present invention as described above is for preventing interference with the movement of the plate-like object 2 flowing inside the plate-shaped member guide member 12, The mesh 3 wound from the lateral direction between the guide members 12 can be supplied continuously and in this embodiment, one sheet is formed between the two sheets 2 produced by the two extruders 1 A synthetic resin or metal mesh 3 is supplied.

The platelets 2 of the fluid synthetic resin flowing along the two die 11 and the plate-like member guide member 12 are discharged through the upper and lower conveying rollers 14 and the mesh 3 are supplied between the two plate bodies 2.

The composite sheet material 4 in a state where the mesh 3 is embedded between the two sheet materials 2 is moved by the conveying roller 14 and the composite sheet material 4 is conveyed by the cooling means 15 Cooled and discharged.

According to the present invention, since the mesh can be inserted as it is between two platelets heated and extruded in an extruder, the platelets can be quickly produced as a flaky platelet without the need to separately heat the platelets.
