Compared with the prior art, the leather ball sheet manufactured by the manufacturing method does not crack or tear when being processed by thinner, and has high strength and good performance.)

1. The manufacturing method of the high-strength leather ball piece is characterized by comprising the following steps:

s1, cutting the surface material according to the required size to obtain a leather ball piece;

s2, processing a groove along the peripheral edge of the leather ball sheet by a high-frequency processing method or a hot plate processing method, and forming a joint part on the inner wall surface of the groove by the heat energy of the high-frequency processing method or the hot plate processing method;

and S3, pressing the leather ball sheet into the mould, so that the joint parts are jointed together along the central line of the groove.

2. The method of manufacturing a high strength leather ball according to claim 1, wherein the sectional shape of the groove is an inverted triangle or an inverted trapezoid.

3. The method of claim 1, wherein the bottom edge of the last leather ball is formed with a slope that is in transition with the bottom arc of the leather ball and the slope is in transition with the side arc of the leather ball.

Technical Field

The invention relates to the technical field of football manufacturing, in particular to a manufacturing method of a high-strength leather ball piece.

Background

Football is a single sport with feet as main part and has strong antagonism, and various actions allowed by the rules adopted by athletes in the competition include running, sudden stop, turning, falling, jumping, collision and the like, and the football competitions fiercely with opponents, and has long competition time, more audiences and large competition field, which are beyond the reach of other sports.

The football is round, is mostly made of leather materials, and is generally formed by splicing 12 regular pentagonal leather ball pieces and 20 regular hexagonal leather ball pieces. The manufacturing method of the leather ball piece of the football in the prior art comprises the following steps: obtaining a leather ball sheet with a rectangular section; processing a step notch along the peripheral edge of the leather ball sheet, then forming a joint part on the bottom surface and the side surface of the step notch under the action of heat energy, and finally pressing the leather ball sheet into a mould so as to adhere the bottom surface and the side surface of the step notch together. However, in order to meet the requirement on the weight of the football, the leather ball sheet is thin, and a step notch is processed on the leather ball sheet, so that when the bottom surface of the step notch is bonded with the side surface, cracks or fractures easily occur at the joint of the bottom surface of the leather ball sheet corresponding to the step notch and the side surface, the strength of the leather ball sheet is poor, and the requirement of modern football on the leather ball sheet which is higher and higher cannot be met.

Accordingly, the prior art is subject to improvements and enhancements.

Disclosure of Invention

The invention aims to provide a method for manufacturing a high-strength leather ball piece, which solves the technical problems in the prior art.

The invention achieves the above purpose by the following technical means:

a manufacturing method of high-strength leather ball comprises the following steps:

s1, cutting the surface material according to the required size to obtain a leather ball piece;

s2, processing a groove along the peripheral edge of the leather ball sheet by a high-frequency processing method or a hot plate processing method, and forming a joint part on the inner wall surface of the groove by the heat energy of the high-frequency processing method or the hot plate processing method;

and S3, pressing the leather ball sheet into the mould, so that the joint parts are jointed together along the central line of the groove.

As a further aspect of the present invention, the cross-sectional shape of the groove is an inverted triangle or an inverted trapezoid.

As a further proposal of the invention, the bottom edge of the last leather ball sheet is a bevel which is in arc transition with the bottom surface of the leather ball sheet and the bevel is in arc transition with the side surface of the leather ball sheet.

Compared with the prior art, the invention has the beneficial effects that:

the leather ball sheet manufactured by the manufacturing method has the advantages that the leather ball sheet does not crack or tear when being processed in a thinner way, the strength of the leather ball sheet is high, and the performance is good.
