In the prior art, the circumferential surface of the outer sleeve 20, which is composed of only the suction holes corresponding to the longitudinal suction holes 22-1 of the present invention and is not constituted of the longitudinal suction holes 22-1, A problem arises that a food packaging film is not adsorbed to the outer sleeve 20 on the circumferential surface of the sleeve 20. However, the present invention is not limited to the case where the longitudinal suction holes 22-1 in the longitudinal direction of the outer sleeve 20 and the transverse direction So that the film for food packaging is always kept adsorbed on the outer sleeve 20, so that the sagging of the film for food packaging does not occur and the foreign matter attached to the film for food packaging is always sucked .

The center of a row of the lateral suction holes 22-2 in the center of the outer sleeve 20 and the center of one row of the lateral suction holes 22-2 adjacent to the row of the lateral suction holes 22-2 Of the longitudinal suction hole 22-1 and the center line of the longitudinal direction of the lateral suction hole 22-2 are aligned with each other, Since the center of the longitudinal suction hole 22-1 and the center of the lateral suction hole 22-2 coincide with the center of the longitudinal suction hole 22-1 in the center of the outer sleeve 20, -1) is formed by the center of the longitudinal suction holes 22-1 of the other row adjacent to the center of the suction holes 22-1 and 22-2.

When the suction angle α is less than 25 °, the center line of the longitudinal direction of the lateral suction hole 22-2 is located at the apex of the outer circumference of the outer sleeve 20 so that the outer peripheral surface apex of the outer sleeve 20, The angle at which the suction guide 30 sucks dust or foreign matter is reduced in a forward or a rearward direction with respect to a line connected to the center of the outer sleeve 20 at the contacted portion so that the suction angle? The preliminary suction angle of the dust or foreign matter before reaching the suction guide 30 is reduced and the suction angle alpha is integrated with the suction guide 30 so that the suction angle [ After passing through the position, it is not sucked, but the finishing suction angle to suck dust or foreign matter becomes small.

When the suction angle? Is 36 degrees or more, the longitudinal centerline of the lateral suction hole 22-2 is positioned at the apex of the outer circumference of the outer sleeve 20 so that the apex of the outer circumference of the outer sleeve 20, A preliminary suction angle and a finishing suction angle are increased to be greater than or equal to 36 ° forward or rearward relative to a line connected to the center of the outer sleeve 20 at the contact portion, but actual preliminary suction and finish suction are not performed.

When the lateral suction holes 22-2 are formed in 12 rows on the outer circumferential surface of the outer body of the outer sleeve 20, the suction angle becomes 30 °, and the lateral suction hole ends of the first row and the first row, The first end of the ball is overlapped and the first end of the horizontal suction hole of the third row and the first row of the horizontal suction hole is overlapped with the first end of the horizontal suction hole of the fourth row and the first end of the horizontal suction hole of the second row and the second row, And the first end of the third row, second row transverse suction hole and the fourth row third stage transverse suction hole are overlapped with each other so that the lateral suction hole always communicates with the suction guide during rotation of the outer sleeve 20 so that the outer sleeve 20 So that dust or foreign matter is always sucked in.

That is, when the preceding lateral suction hole communicating with the suction guide 30 of the lateral suction hole 22-2 and sucking the dust advances and passes through the suction guide 30, the end of the preceding lateral suction hole is guided by the suction guide The front end of the traverse side suction hole starts to communicate with the suction guide 30 so that the suction guide 30 can always suck dust or foreign matter.

In other words, as the process for producing the packaging film, the vinyl wrap, or the pouch is performed, the single-row single-row horizontal suction hole of the film foreign material suction device 1 is communicated with the suction guide 30, At the end of the suction of dust or foreign matter adhering to the first row and the suction of the dust or foreign matter of the first row of the first row, the second row, second row transverse suction hole communicates with the suction guide to suck dust or foreign matter adhered to the film for food packaging So that the suction guide 30 can always absorb dust or foreign matter.

The longitudinal suction holes 22-1 are formed in a longitudinal direction orthogonal to the longitudinal center of the lateral suction holes 22-2. That is, the width of the longitudinal suction holes 22-1 is larger than the width of the lateral suction holes 22-2. 2, the longitudinal suction hole 22-1 always communicates with the suction guide 30 when the lateral suction hole 22-2 is sucked, so that the longitudinal suction hole 22-1 is always maintained in the suction state.

The bending guide 32 has a band-like shape which is inclinedly bent in an outward direction, that is, in a direction in which the opposing vertical guide 31 is not formed, and is protruded to the inner surface of the outer sleeve 20 at the end of one vertical guide 31 Shaped plate which is integrally bent at an end of the other vertical guide 31 and is bent obliquely outwardly and protrudes to the inner surface of the outer sleeve 20 so that the two strip- As shown in Fig.

When the suction guide 30 is not constituted by the vertical guide 31 and the bending guide 32, the inclined guide 33 is formed by the inclined guide 33, Projecting in a flange shape and inclined up to the inner surface of the outer sleeve 20.

The inclined guide 33 is formed of a band-like plate which is integrally projected from the center of the inner sleeve 10 at one cut-out portion 13 and which is integrally formed at the center of the inner sleeve 10 with the other cut- Shaped plate projecting from the inclined surface, and the two strip-shaped plates are formed in such a shape that a strip-shaped flange facing obliquely to each other protrudes.

The width of the vertical guide 31 is made smaller than the width of the bending guide 32 so that the suction speed of the vertical guide 31 is increased so that relatively large foreign matter is sucked in quickly and the inner surface of the outer sleeve 20 is inclined The suction wind is smoothly guided by the bent guide 32 and the inclined guide 33 so that the noise is reduced.

When the inner sleeve 10 having the suction guide 30 is fixed to the outer sleeve 20, the outer sleeve 20 rotates about the inner sleeve 10,
