Description

Extruder that can select cooling method {EXTRUDER TO SELECT COOLING TYPE}

The present invention relates to an extruder, and more particularly, to an extruder capable of selecting a cooling method.

In general, an extruder is a type of pressure molding machine, and is a device that melts and pushes a material. For example, the melt discharged from the extruder may be introduced into an extruder having a molding nozzle to form an extrudate in a shape corresponding to the molding nozzle.

A conventional extruder introduces the molten material into an extruder, extrudes the extrudate, and cools the extrudate to complete the extrudate. However, the cooling method is provided differently depending on the material of the extruded product, the purpose of use, and the length.

That is, materials requiring short length or ductility adopt an air-cooled cooling method in which slow cooling in air is adopted, and materials requiring rapid cooling adopt a water-cooling cooling method in which rapid cooling is performed in water.

However, since most of the conventional extruders adopt one cooling method, in some cases, when an order for an extrudate that requires a different cooling method is received, there is a problem of installing an additional extruder or canceling the order. there was.

On the other hand, when the air-cooled cooling unit 300 is coupled to the extrusion molding machine 100 as shown in (b) of FIG. 8, the folding driving cylinder 380 is driven to increase the length of the folding driving rod 381. . Accordingly, the auxiliary table 370 is spread horizontally on the cooling table 310 and is positioned under the molding nozzle 110.

Accordingly, the extruded product A discharged from the molding nozzle 110 may be moved to the auxiliary table 370.

Here, as shown in FIG. 5, the cooling table 310 of the air-cooled cooling unit 300 and the water-cooled cooling body 210 of the water-cooled cooling unit 200 are side-coupled to each other by a connection plate 390. Accordingly, when the air-cooled cooling unit 300 is moved by a change in the length of the folding drive rod 381, the water-cooled cooling unit 200 is also moved in conjunction therewith.

The optional driving unit 400 includes a water-cooled cooling unit 200 and an air-cooled cooling unit so that any one of the water-cooled cooling unit 200 and the air-cooled cooling unit 300 arranged side by side is positioned coaxially with the extruder 100.

The front end of the positioning rod 421 is fixedly coupled to the rod coupling frame 360 formed under the cooling table 310. Accordingly, a change in the length of the positioning rod 421 leads to linear movement of the cooling table 310.

The transfer table 500 is located at the rear end of the water-cooled cooling unit 200 and the air-cooled cooling unit 300 coaxially with the extrusion molding machine 100. The transfer table 500 is moved along the water-cooled cooling unit 200 or the air-cooled cooling unit 300 and the cooled extrudate A is loaded.

The extruded product A loaded on the transfer table 500 is transferred to the loading place by a transfer robot (not shown). The transfer table 500 is provided with a plurality of third transfer rollers 510 along the longitudinal direction to help transfer the extruded product (A).

The operation process of the extruder 1 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 7.

The extruder 1 according to the present invention includes an extrusion molding machine 100 through which the molten material is extruded, a water-cooled cooling part 200 and an air-cooled cooling part 300 arranged side by side in front of the extrusion molding machine 100, and a water-cooled type.

The operator selects the cooling units 200 and 300 to be located between the extruder 100 and the transfer table 500 by driving the selective use driving unit 400 according to the molten material.

For example, when the extrudate (A) is suitable for the water-cooled cooling method, the water-cooled cooling unit 200 is coupled to the extruder 100. To this end, as shown in Figs. 1 and 4, the cooling unit movable cylinder 420 is driven so that the water-cooled cooling body 210 is located coaxially with the extruder 100 so that the water-cooled cooling body 210 and the cooling table ( 310).

When the cooling unit movable cylinder 420 is driven so that the length of the positioning rod 421 increases to ℓ1 as shown in FIG. 1, the position is fixed by the rod coupling frame 360 to the positioning rod 421. The cooling table 310 is moved in a direction away from the extrusion molding machine 100. The second wheel 351 coupled to the wheel coupling frame 350 provided under the cooling table 310 is moved along the wheel moving rail 410.

When the water-cooled cooling body 210 is coaxially positioned in the extrusion molding machine 100, the operator drives the moving pipe length control cylinder 255. As shown in Figure 6 (a), the moving pipe 253 accommodated in the main body coupling pipe 251 is when the length of the length adjusting rod 255a is increased by the driving of the moving pipe length adjusting cylinder 255, FIG. As shown in (b) of 6, the main body coupling pipe 251 is exposed to the outside.

Thereby, the moving pipe connector 254 advances and is coupled with the molding nozzle 110. When the moving pipe connector 254 is combined with the molding nozzle 110, the operator proceeds with the extrusion process.

The extruded product (A) extruded from the extrusion molding machine 100 and discharged to the molding nozzle 110 flows into the water-cooled cooling body 210 through the moving pipe connection pipe 254, the moving pipe 253, and the body coupling pipe 251 do.

The extruded product (A) is pulled by the transfer arm 231 of the extruded material transfer means 230, is moved along the water-cooled cooling body 210, and transferred to the transfer table 500. The extrudate (A) located on the transfer table 500 is picked up by a transfer robot (not shown) and moved to the loading place.

On the other hand, when the air-cooled cooling method is to be used while the water-cooled cooling method is being used, the operator separates the nozzle coupling part 250 from the forming nozzle 110. By driving the moving pipe length adjusting cylinder 255, the length of the length adjusting rod 255a is shortened to ℓ2 as shown in FIG. 2. Thereby, the moving pipe connection pipe 254 is spaced apart from the molding nozzle 110.

When the separation of the molding nozzle 110 and the moving pipe connection pipe 254 is completed, the operator drives the optional driving unit 400 so that the cooling table 310 of the air-cooled cooling unit 300 is transferred to the extruder 100 and the transfer table. Move it so that it is located coaxially with (500).

The operator drives the cooling unit moving cylinder 420 to adjust the length of the position adjustment rod 421 to be shortened. Thereby, the cooling table 310 is moved to the front of the extrusion molding machine 100, and the water-cooled cooling body 210 is moved to the right side of the extrusion molding machine 100.

As shown in (b) of FIG. 7, the operator arranges the connection plate 390 in the spaced space between the cooling table 310 and the extruder 100. When the extrusion molding machine 100 is driven and the extruded product A is discharged to the molding nozzle 110, the extruded product A is moved along the connecting plate 390 and the cooling table 310. At this time, the plurality of second transfer rollers 320 provided on the cooling table 310 are driven to rotate and automatically transfer the extruded product A to the transfer table 500.
