Technical field

The present invention relates to the rain-tight seam constructions and its manufacturer of umbrella manufacturing technology field more particularly to a kind of umbrella Method.

Background technique

In life, umbrella is indispensable article, it is well known that the umbrella cover of umbrella is spherical structure or paraboloid knot Structure, umbrella cover are to be combined by the triangle umbrella cloth and triangle umbrella cover Bouyei time of muti-piece with linear slit, and umbrella cover is by four pieces or more Triangle umbrella cloth is combined with linear slit, rather than complete integrated umbrella cover.Due between triangle umbrella cloth and triangle umbrella cloth It is needle seam connection, the non-stitching holes gap between stitching holes and stitching holes is just certainly existed on the umbrella cover of umbrella, and There are fit-up gaps with the assembly node of umbrella frame at the top of umbrella cover, therefore all umbrellas all have the possibility of roof leaking.Especially big sudden and violent In the case where rain, since the dynamics and density of rainwater drippage are all bigger, the water tension in the gap between pin hole and pin hole is not enough to Resist the strength dripped, just cause the obvious roof leaking of umbrella, thus it is proposed that a kind of rain-tight seam construction of umbrella and its Manufacturing method solves problem above.

Summary of the invention

The purpose of the present invention is to solve existing umbrella exists in the prior art, there are the pin hole of splicing seams and umbrella covers The shortcomings that top leads to roof leaking there are fit-up gap, and the rain-tight seam construction and its manufacturing method of a kind of umbrella proposed.

To achieve the goals above, present invention employs following technical solutions:

A kind of rain-tight seam construction of umbrella, including the unilateral cloth of several triangles are designed, several unilateral cloth of triangle are logical It crosses suture and forms round umbrella cover, pilot hole is run through equipped with umbrella frame in the center of circle portion of the circle umbrella cover, the unilateral cloth of triangle It is respectively coated inside and outside suturing part equipped with bar shaped film, described be respectively coated inside and outside pilot hole is equipped with annular glue Piece.

Preferably, the coating width of the bar shaped film is 2-3 times of the suturing part width.

Preferably, the annular film is pressed together on side of the bar shaped film far from the unilateral cloth of the triangle.

Preferably, the bar shaped film and the annular film are PU plastic structure, the bar shaped film and the annular The coating processes of film are to heat seamless applying technique.

Preferably, the coating thickness of the bar shaped film and the annular film is 0.1-0.5mm.

A kind of manufacturing method of the rain-tight seam construction of umbrella comprising the steps of:

S1, the seam crossing of the unilateral cloth of adjacent two piece triangle of umbrella cover is stitched and fastened, and is connect what is stitched and fastened It is folded at seam, suture is recycled to suture the position of folding, form suturing part, several unilateral cloth of triangle are formed by suture Pilot hole is run through equipped with umbrella frame in the center of circle portion of round umbrella cover, the circle umbrella cover；

S2, cleaning decontamination operation is carried out by the suturing part in step S1 and through the interior outside of pilot hole；

S3, bar shaped film will be respectively coated inside and outside the suturing part in step S2, pilot hole will be run through in step S2 Inside and outside annular film is respectively coated.

S4, the round umbrella cover that bar shaped film and annular film are had in step S3 is carried out by cold wind drying work using air-cooler Then industry, drying time 5-10min carry out hot-air seasoning, drying time 1-5min.

S5, umbrella cover round in step S4 is subjected to whole boiling hot operation, the travel speed of ironing equipment is 10-15m/min, is obtained The rain-tight seam construction of umbrella.

Preferably, in step s 2, the cleaning decontamination operation includes removing the extra raised the end of a thread of suturing part and utilizing to inhale Dirt device absorbs excess fabric dust.

The rain-tight seam construction and its manufacturing method, beneficial effect of a kind of umbrella proposed by the present invention are: the present invention By the way that bar shaped film and annular film are respectively coated on pilot hole at the top of the suturing part and umbrella of umbrella, make umbrella The stitching holes and the assembly node at the top of umbrella of suturing part reach obturation effect, comprehensively closed umbrella cover, have preferable anti- Leak function, practical.
