FIGS. 5A, 5B and 5C are a perspective view and an assembly view of upper and lower forming rollers for forming an embossed shape on the surface of the filter element before manufacturing the embossing air filter according to the present invention, wherein upper and lower forming rollers 15, The upper and lower emboss punches 17 and 17a and the upper and lower bent line punches 18 and 18a are projected on the outer surface of the upper and lower embossing punches 17 and 17a.

The upper and lower embossing punches 17 and 17a are formed in a ring shape with a plurality of ridges 19 and ridges 20 in the outer circumferential direction.

However, in the upper and lower embossing punches 17 and 17a, a plurality of, preferably eight, idle grooves 21 are axially deeply deeper than the depth of the trough 20.

In the axial direction, eight idle grooves 21 are formed at an angle of 45 degrees.

Therefore, the annular ridge 19 and the valley 20 are axially cut by the idle groove 21 to lose a continuous annular shape.

The idle groove 21 is formed to have a predetermined width. The bent line punch 18 is press-fitted and fixed.

On the other hand, the press-fitted upper and lower bent line punches 18 and 18a are installed one by one between the idle grooves 21, and are installed in total of four at 90 degree angles.

However, the above-described configuration is common to the upper and lower forming rollers 15 and 16, and the present invention is applicable to a case where the upper and lower forming rollers 15 and 16 are engaged and rotated, (19) and the valleys (20) are formed such that the valleys (20) of the lower forming roller (16) and the mountains (19) are intermeshed.

Further, a portion where the crests 19 of the upper and lower shaping rollers 15 and 16 are in contact with the valleys 20 is formed as 'S'.

Both ends of the upper embossing punch 17 of the image forming roller 15 are provided with projections 22 and recesses 23 are formed at both ends of the lower embossing punch 17a of the lower forming roller 16.

The depth of the concave portion 23 and the height of the protruding portion 22 are the same and the concave portion 23 and the protruding portion 22 are mutually guided when the upper and lower forming rollers 15 and 16 are rotated to rotate .

The upper and lower bent line punches 18 and 18a have a rectangular shape and the front and rear faces 18c and 18d except for the central portion formed on the continuous edge with the end 18aa have the escape grooves 18b having a predetermined depth And the height thereof is the same as that of the upper and lower embossing punches 17 and 17a.

The upper and lower bent line punches 18 and 18a are formed at the same height as the upper and lower embossing punches 17 and 17a so that the upper and lower bending lines 4 and 5 are formed on the surface of the filter element 10 at the time of punching. And the filtering grooves 2b.

In addition, a rectangular punch 18e is formed at the end 18aa of the upper bending line punch 18, and the inside thereof is opened, and the outside of the square punch 18e is surrounded by a thickness of 1-2 mm.

Therefore, when the upper bending line punch 18 is rotated, a rectangular pitch preform 6 is formed on the surface of the filter element 10 by the rectangular punch 18e.

The structure of the rectangular punch 18e with the inside opened is intended to improve the efficiency of molding at the time of molding.

The height of the square punch 18e is equal to the height of the center portion and the upper embossing punch 17 so that when the upper and lower forming rollers 15 and 16 are rotated to rotate, 19 and the valleys 20 are engaged with the valleys 20 of the lower forming roller 16 and the crests 19 and the upper and lower bent line punches 18, 18a are staggered with each other.

That is to say, the upper bent line punch 18 press-fitted into the idle groove 21 of the upper forming roller 15 interlocks with the idle groove 21 without the lower bent line punch 18a of the lower forming roller 16 .

6A and 6B are a perspective view and a working state view showing the bending gear and the bending guide for bending the filter element. The feed element for feeding the filter element 10 through the upper and lower forming rollers 15 and 16, The roller 24 is positioned in front of the primary bending guide 25. [

The feeding roller 24 transports the filter element 10 passing through the feeding roller 24 as a normal roller by the rotational force.

A primary bending guide 25 having a structure through which the filter element 10 can pass is positioned behind the feeding roller 24 to guide the filter element 10 to be conveyed.

That is, the front and rear openings are opened so as to feed the filter element 10, but the opened height and width are formed to match the thickness and the width of the filter element 10.

On the other hand, the filter element 10, which has passed through the primary bending guide 25 , is conveyed to the bending device 26 according to the present invention .

The bending device 26 is formed with a plurality of second bending guides 27 for guiding the fed filter element 10 and serrated upper and lower bending gears 28 and 29 .

The width of the secondary bending guide 27 is formed to be equal to the width of the filter element 10, but the height is equal to the height of the embossing air filter 9 which is finally folded and folded .

The reason for limiting the height to the height of the embossing air filter 9 is to make the height of the embossing air filter 9 taken out after folding is constant.

On the other hand, the upper and lower bending gears 28 and 29 integrally formed with the upper and lower bending shafts 30 and 31 are also composed of a plurality of upper and lower gears 28a and 29a.

This, to the large number of phase, the control (28a, 29a) are folded kkeokeo the upper and lower bend lines (4, 5) and the pitch pre-molded portion (6) that is formed on the surface of the filter element (10).

In particular, when folding the lower folding line 5, the diagonal of the lower folding line 29a of the lower folding shaft 31 is positioned in a vertical form.

The reason for the vertical position of the teeth 29a is that the lower bent line 5 of the filter element 10 to be conveyed through the primary bending guide 25 hits one side of the lower teeth 29a And the upper bending line 4, which is bent at the rear side from the lower folding line 5, rotates in the direction of the hook 28a.

The gear 28a is positioned such that two gears of the plurality of gears are disposed in a downward direction of 90 degrees (reverse 'Y' shape), and a bending groove 28b is formed between the two gears 28aa and 28aaa .

The upper bending line 4 bumps against one surface of the rear gear 28aaa of the front and rear gears 28aa and 28aaa positioned with the bending groove 28b therebetween, as soon bent at the bending line 4 is at the same time kkeokeo folding structure.

Therefore, the filter element 10, which is continuously folded and folded by the rotation of the upper and lower bending shafts 30 and 31 , passes through the second bending guide 27, and the embossing air filter 9 according to the present invention is completed .

On the other hand, on the front side of the feeding roller 24, a hot melt application gun 24a for adhering the folded embossing air filter 9 is mounted.

The hot melt coating gun 24a is applied to one end of the preliminary pitch forming part 6 formed in the filter element 10 in cooperation with the feeding of the filter element 10 and applying hot melt.

The applied hot melt causes the filter element 10 to adhere to the filter element 10 at the same time as the filter element 10 is folded .

7 is a perspective view of an air filter processed by an apparatus for manufacturing an embossing air filter according to the present invention.

Also the air flow space (2a) is formed between the embossed between the air filter 9 as kkeokyeo folded arranged in a line as shown in the multi-stage 7.

The air flowing space 2a is a place where air mixed with impurities flowing from the outside passes through the filter element 10 and impurities are filtered.

On the other hand, the air flow space 2a is a space formed by bending the preliminary pitch forming part 6 and the upper bending line 4 according to the present invention.

The preliminary pitch forming section 6 is formed at both ends of the embossing air filter 9 and is formed in a rectangular shape so as to enter the center of the bending line 4 of the embossing air filter 9 It becomes narrower.

Therefore, the both ends and the center of the embossing air filter 9 are formed in a space proportional to the width of the rectangular preliminary pitch forming part 6 and in proportion to the width of the upper bending line 4, .

On the surface of the filter element 10, a filtering groove 2b is formed by the rotation of the upper and lower forming rollers 15 and 16 as shown in FIG. 5C.

Therefore, the filtering grooves 2b are the same as the shapes of the ridges 19 and the valleys 20 of the upper and lower embossing punches 17 and 17a formed on the outer surfaces of the upper and lower forming rollers 15 and 16.

That is, an S shape groove is formed at a portion where the mountain 19 and the valley 20 are in contact with each other, which is the greatest feature of the present invention, to form the embossing air filter 9 according to the present invention.

As described above, the manufacturing apparatus for manufacturing the embossing air filter according to the present invention can achieve productivity and cost reduction by automatic forming by the upper and lower forming rollers and by increasing the folding speed by the upper and lower bending gears .

In addition, the embossing air filter produced by the manufacturing apparatus according to the present invention has a filtering groove formed on the surface thereof so as to smoothly introduce air and improve the function of filtering.

In addition, the embossing air filter according to the present invention has an advantage that the interval of the pitch is constant and the gap between the filter elements at the time of bending is not formed because the preliminary pitch forming portion is formed.
