Description

Tube Making Machine Using Waste Plastic {omitted}

The present invention relates to a tube making machine for the purpose of manufacturing pipes that are frequently used in the industry using waste plastics, resins, and the like. In the past, items that are difficult to corrode, such as plastics, have become the main culprit of environmental pollution. Recycling methods have been developed as required, but currently, only simple products such as sidewalk blocks can be manufactured.

In addition, automated processes are applied to make pipes in the steel mill, but the materials used are raw materials. Even if recycled materials are used, production efficiency is reduced and quality is reduced due to the complicated manufacturing process.

Designed to solve the above problems, the tube making machine is a tube making machine that melts waste plastics in a conventional electric melting furnace and extrudes them from a material container to form a pipe, which is easily operated, has excellent quality, and can produce a large amount of pipes in a short time. It is designed to be configured to be.

70 Electric Melting Furnace 80

The present invention is the supply pipe 60 is connected between the electric melting furnace 70 and the cylindrical material container 10 for melting the waste plastic injected by the installation of a conventional electric heater to supply the molten waste plastic to the material container 10 The inside of the material container 10 is provided with a reciprocating piston 50 which is operated by hydraulic pressure, and the introduced molten plastic is extruded to the front side, and a pipe mold is installed on the front part of the material container 10, but the pipe The mold is composed of a cylindrical outer mold 20 fixed to the front of the material container 10 and a round rod inner mold 30 reciprocating, the inner mold 30 in the outer mold 20 radially It is inserted with a gap and the molten plastic is filled between the gap between the outer mold 20 and the inner mold 30, the operating rod 40 is installed at the opposite end of the material cylinder 10 of the inner mold 30 On the outer circumference of the operating rod 40 The slidable flange type machine 80 is mounted to properly hit the end of the pipe located on the outer circumference of the inner mold 30 after extrusion, so that the pipe is easily separated from the inner mold 30. It relates to a pipe mill using waste plastic.

The temperature of the solution injected into the material container 10 is suitable for around 150 degrees Celsius, and around the cylindrical material container 10 to prevent the material from being cooled by the ambient temperature of the material container 10 due to higher than room temperature. The heating wire is wound at intervals and a temperature sensor is installed inside the material container 10 so that the heating wire is automatically turned on and off according to the temperature change so that the solution inside the material container 10 maintains a constant temperature.

The pipe extruded from the material container 10 should be cooled to an appropriate temperature in the mold, and thus, a cooling water pipe is wound around the outer mold 20 of the pipe mold. Cooling water is circulated by the general circulation pump in the cooling water storage tank installed in the adjacent part of this tube.

According to the ambient temperature and setting conditions, it is preferable to control the cooling water circulation pump on or off or to appropriately change and adjust the rotation speed of the step motor installed in the circulation pump.

When waste materials such as plastic and resin are melted in the electric melting furnace 70 and supplied primarily through a pipe connected to the material container 10, the piston installed inside the material container 10 is moved forward by hydraulic pressure to the molten waste. The plastic is extruded into the pipe mold. Naturally, the material supply to the material container 10 is stopped when the piston moves forward. The piston which extruded the material into the mold again retreats to the rear of the material container 10, and when the retracting piston is stopped, the supply of material to the inside of the material container 10 from the electric melting furnace 70 proceeds in the same manner as before. do.

Therefore, as the supply of the material is made intermittently, as another embodiment of the present invention, two pipe mills are installed in parallel at the same time, and the electric melting furnace 70 is installed at the center point. Thus, while the first tuber is in the extrusion stroke, i.e., while the piston is moving forward, the second tuber is in the retracted state. Thus, the material is supplied to the second tuber and the second tuber is pushed out while the piston of the first tuber is retracted. This can be configured to proceed so that the material can be fed to the first tuber so that the material can be continuously supplied from the electromelting furnace 70.

In the present invention, the reciprocating motion of the operating rod formed at the rear of the piston and the inner mold 30 in the material container 10 is performed by a conventional hydraulic device. In this case, the hydraulic pressure is usually about l50 kg / cm 3.

Pipe mold is composed of a cylindrical outer mold 20 and a round rod inner mold 30, the outer mold 20 is fastened by bolts to the flange portion of the material container 10, but the inner mold (30) ) Is a linear movement in a reciprocating direction and the outer diameter is designed to be smaller than the outer mold 20 so that inserting the inner mold 30 into the outer mold 20 creates a gap in the radial direction, which is the The thickness of the pipe can be freely controlled by appropriately adjusting the gap between the inner mold 30 and the outer mold 20 in the mold.

When the extrusion operation is completed and the piston proceeds to the front of the material box 10 proceeds backward and the pipe is properly cooled by the cooling water circulating the cooling water pipe installed around the outer mold 20, the inner mold 30 The material container 10 is conveyed in the opposite direction to the installed position. At this time, the pipe is coupled to the outer peripheral portion of the inner mold (30) concentrically conveyed together. The inner mold 30 and the pipe stop at a predetermined position and at the same time, the pipe is appropriately separated from the inner mold 30 by the launcher 80 which slides on the operating rod formed at the end of the inner mold 30. .

The launcher machine 80 is manufactured in a hollow shape and fitted into an operating rod, and is manufactured in a hollow shape to move the operating rod shape, and is manufactured in a flange shape in order to strike the pipe. A rolling means such as a roller is installed at the bottom of the operating rod and the machine 80 connected to the internal mold 30, and a rail is installed at the bottom thereof so that the internal mold 30, the operating rod, the machine 80, and the like are hydraulically operated. The rollers to be conveyed are configured to move smoothly on the rail. Hydraulic force is applied to the transfer of the internal mold 30, the operating rod, the machine 80.

The present invention relates to a pipe making machine that makes useful pipes for industrial use by using waste plastics and resins, and plays an important role in the reduction and disposal of industrial waste and household waste that destroys the environment, and is also effective in recycling resources. . The operator can work effortlessly by the simple tube manufacturing process and the simple operation of the machine, and the work process is smooth and the power transmission is accurate by braking the machine by hydraulic pressure. Since the process from waste plastic to piping is short, power savings are required and cost savings are large due to shortening of working time.
