Embodiment 1

[0032] see Figure 1-4 , the present embodiment provides a ball imitating manual machine stitching, including a ball skin 2 and a bladder 1, the ball skin 2 includes a plurality of sheet-shaped monomers 24, and the sheet-shaped monomers 24 are provided with surfaces from the outside to the inside. Material layer 21, buffer layer 22 and base layer 23, the adjacent sheet-shaped monomers 24 are sewed together, and the periphery of the outer surface of the sheet-shaped monomer 24 is provided with a sewing edge 25, and the sewing edge 25 is Alternate concavo-convex grooves 251 and protrusions 252 are provided, and the grooves 251 and protrusions 252 are inlaid with each other on the seams 25 of adjacent sheet-shaped monomers 24 .

[0033] The shape of the sheet-shaped monomer 24 can be pentagonal, hexagonal, curved, fan-shaped, plum-shaped, straight, drum-shaped, S-shaped or circular. In this embodiment, the sheet-shaped monomer 24 The shape is a regular pentagon, the protrusion 2...

Embodiment 2

[0044] Compared with Embodiment 1, the difference of this embodiment is that the angle α between the two sides of the groove is 30°, the depth of the groove is 1 mm, the number of sewing stitches on the sewing edge is 6 stitches / inch, and the thickness of the sewing thread is 2400D, the tension N of the bottom thread in the sewing machine is 4kgf during sewing, and the temperature is 70°C during hot pressing and shaping. Two sheet-shaped monomers are sewn by the above sewing method and then tested for tensile strength.

Embodiment 3

[0046] Compared with Embodiment 1, the difference of this embodiment is that the angle α between the two sides of the groove is 40°, the depth of the groove is 2 mm, the number of sewing stitches on the sewing side is 7 stitches / inch, and the thickness of the sewing thread is 2700D, the tensile force of the bottom thread in the sewing machine is 5kgf when sewing, and the temperature is 80°C when hot-pressing and shaping. Two sheet-shaped monomers are sewn by the above sewing method and then tested for tensile strength.

Abstract

The invention relates to the technical field of sports balls, and discloses a method for preparing balls imitating manual machine sewing, comprising the following steps: making a composite material; punching the composite material into a sheet-shaped monomer; adjusting the tension of the bottom thread in a sewing machine It is 3-6kgf, and the sheet-shaped monomers are sewed together to make a ball skin; the ball skin is covered on the bladder to make a sphere; the sphere is put into a mold of a corresponding size, heated and controlled to carry out hot pressing and shaping, the present invention It also discloses that the above-mentioned preparation method imitates hand-sewn balls. The imitated hand-sewn balls prepared by the present invention not only have good appearance and visual appearance, but also have similar appearance effects to hand-sewn balls, and the strong enemy of sewing is also close to hand-sewn balls.

Description

technical field [0001] The invention relates to the technical field of sports balls, in particular to a method for preparing a hand-imitated machine-sewn ball and the prepared hand-imitated machine-sewn ball. Background technique [0002] Sports balls on the existing market are divided into organic sewing balls and handmade balls according to different processing methods. When handmade balls are processed, they are stitched manually. Although the appearance of handmade balls is better, the stitching of sheet-shaped monomers Stronger and stronger, but the processing time is long, the efficiency is slow, and the manufacturing cost is high. The ordinary machine-sewn balls are all compounded with this material: PU, PVC, TPU and the foam layer, and the base bonded pieces are directly used by a sewing machine. There are certain defects in the sewing: the edge of the suture is obvious, which affects the appearance and vision; the stitches leak outside, and obvious pinholes can be s...
