It may be inserted between the overlapped portions of the first sheet 610 and the second sheet 620.

The hot air body 420 is coupled to the connection bar 410. In addition, the hot air body 420 is provided to form and spray hot air in various ways. For example, the hot air body 420 may be provided with an intake fan (not shown) and a heating member (not shown) mounted to provide hot air. Here, the hot air body 420 may be provided with various other configurations as long as it is provided to form and spray hot air as well as an intake fan (not shown) and a heating member (not shown).

The nozzle 430 is coupled to the hot air body 420 and is provided to spray hot air provided from the hot air body 420 between the overlapped portions of the first sheet 610 and the second sheet 620. There are various methods of spraying hot air between the overlapping portions of the first sheet 610 and the second sheet 620. For example, referring to FIGS. 4 to 7, the nozzle 430 is the first sheet 610. It may be provided to spray hot air by being inserted between the overlapped portion of the and the second sheet 620.

When the connecting bar 410 is rotated from FIG. 2, as in FIG. 4, the hot air body 420 and the nozzle 430 coupled to the connecting bar 410 are also rotated so that the first sheet 610 and the second sheet 620 are rotated. It is located between the overlapped parts of ). In addition, when the first connection bar 411 of the connection bar 410 moves in the direction of the arrow of FIGS. 4 and 5, the nozzle 430 is inserted between the overlapped portions of the first sheet 610 and the second sheet 620. It becomes the same state as in FIGS. 6 and 7.

6 and 7, when the nozzle 430 is completely inserted between the overlapped portions of the first sheet 610 and the second sheet 620, the first sheet 610 and the second sheet ( 620), the hot air is sprayed.

In this way, when hot air is sprayed after the nozzle 430 is inserted between the overlapping portions of the first sheet 610 and the second sheet 620, the hot air sprayed from the nozzle 430 is discharged from the first sheet 610 within the shortest time. ) And the second sheet 620, so the heat of the hot air can be directly transferred to the first sheet 610 and the second sheet 620 while the heat of the hot air is maintained, and thus there is an effect of increasing the efficiency of thermal fusion. .

The handle (not shown) may be coupled to the connection bar 410 or the hot air body 420. After grasping the handle (not shown), the operator moves the connecting bar 410 and the hot air body 420 in the left and right directions, and rotates the nozzle 430 so that the first sheet 610 and the second sheet 620 overlap. Can be inserted between parts.

4 and 6, the nozzle 430 may be inserted between the front wheel 200 and the rear wheel 300 and between the overlapped portions of the first sheet 610 and the second sheet 620. Here, the nozzle 430 may be positioned to be adjacent to the rear wheel 300 when inserted between the overlapped portions of the first sheet 610 and the second sheet 620.

This is, immediately after the first sheet 610 and the second sheet 620 are melted by the hot air sprayed from the nozzle 430, the rear wheel 300 presses the first sheet 610 and the second sheet 620 This is for thermal fusion. That is, the first sheet 610 and the second sheet 620 by placing the nozzle 430 through which hot air is sprayed and the rear wheel 300 pressing the first sheet 610 and the second sheet 620 as close as possible. It is to melt and pressurize almost at the same time to heat-fusion.

Referring to FIG. 8, the nozzle 430 may be formed so that the upper plate 431 and the lower plate 432 are coupled. In addition, at least one spray hole 433 may be formed in the upper plate 431 or the lower plate 432. In FIG. 8, it is shown that the spray hole 433 is formed only on the upper plate 431, but the spray hole 433 may be formed only on the upper plate 431, may be formed only on the lower plate 432, or It may be formed on both the plate 431 and the lower plate 432.

Among the nozzles 430, the hot air body 420 is located on the outside of the nozzle 435 among the nozzle inner side 434, which is a side located near the main body 100, and the nozzle outer side 435, which is a side located farther from the main body 100. Are combined. Accordingly, the nozzle 430 can be easily inserted between the overlapped portions of the first sheet 610 and the second sheet 620.

An inclined portion 436 may be formed between the upper plate 431 or the lower plate 432 of the nozzle inner side 434 or between the nozzle inner side 434 and the nozzle outer side 435. Here, the inclined portion 436 may be formed only on the upper plate 431, may be formed only on the lower plate 432, or may be formed on both the upper plate 431 and the lower plate 432.

In this way, when the inclined portion 436 is formed on the upper plate 431 or the lower plate 432, a sharp portion like a blade is formed at the end of the upper plate 431 or the lower plate 432, so that the first sheet 610 and the second There is an effect of facilitating insertion between the overlapped portions of the sheet 620.

However, if the inclined portion 436 of the upper plate 431 or the lower plate 432 is sharp as the blade, the operator may be wounded, so that the upper plate 431 or the lower plate 432 is It is preferable that the inclined portion 436 is formed dull than the blade.

The weight 500 may be detachably coupled to the main body 100 at a position adjacent to the rear wheel 300. The weight 500 is to increase or decrease the weight of the rear wheel 300.

That is, since the rear wheel 300 is a wheel that presses the melted first sheet 610 and the second sheet 620 as described above, the heavier the more easily pressurized. However, if the rear wheel 300 is too heavy, the moving speed decreases, so the weight 500 can be added or removed in consideration of the material of the first seat 610 and the second seat 620 or the temperature of the hot air. Thereby, it is adjustable so that the rear wheel 300 may apply an appropriate pressure to the first seat 610 and the second seat 620.

Hereinafter, with reference to the drawings will be described the operation and effect of the industrial automatic door sheet thermal welding apparatus 10 according to an embodiment of the present invention.

The operator moves the industrial automatic door sheet heat-sealing apparatus 10 according to an embodiment of the present invention to the upper side of the overlapped portion of the first sheet 610 and the second sheet 620.

At this time, as shown in FIG. 3, the seating groove 210 formed in the front wheel 200 is seated on the support 700 inserted between the overlapped portions of the first sheet 610 and the second sheet 620.

In addition, referring to FIGS. 1 to 2, the operator moves the connecting bar 410 in the left and right direction, and rotates the connection bar 410 in the front and rear directions so that the nozzle 430 of the hot air spray member 400 is moved to the first sheet 610. And the second sheet 620 is moved to a position adjacent to the overlapped portion.

And, as shown in Figs. 4 and 5, the nozzle 430 is moved to the same position as in Figs. 6 and 7 by inserting the nozzle 430 between the overlapped portions of the first sheet 610 and the second sheet 620 When the power source mounted on the main body 100 is operated, the front wheel 200 and the rear wheel 300 move along the upper side of the overlapped portion of the first seat 610 and the second seat 620.

At this time, the nozzle 430 melts the first sheet 610 and the second sheet 620 by directly spraying hot air between the overlapped portions of the first sheet 610 and the second sheet 620, and the nozzle 430 A pressure roller, which is a rear wheel 300 located adjacent to, presses the melted first sheet 610 and the second sheet 620 to be fused.

In this way, the sheet 600 used for an industrial automatic door may be automatically thermally fused. And, according to the automation, there is an effect that the processing time is reduced and a certain quality is guaranteed. In addition, since only the space in which the main body 100 moves is required and the operator's work space is unnecessary, the space utilization is excellent and there is an effect that the sheet 600 can be easily heat-sealed.

In the above, although the present invention has been described by limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following will be described by those of ordinary skill in the art to which the present invention pertains.
