Detailed ways

The present invention is clearly and completely described below.

The baseball and softball of the present invention includes a core, a ball skin, and a line collar in the shape of a suture, and the line collar is a rubber-plastic strip or a fiber strip. The baseball and softball skins, which have been designed and matched with the cores, are made into cardboard cutting molds, and then are cut by a cutting machine are pasted on the outside of the cores. The skins can be one piece or two pieces or more. After smearing the glue with the core respectively, put them into the well-aligned mold together. After appropriate temperature and pressure, the skin and the core are fused and pasted and then taken out, so that the baseball and softball are formed by fitting. The jersey on the sphere, and finally the rubber-plastic strip or twisted and woven fiber strip with the effect of baseball and softball stitching and collar produced by the mold is attached to the jersey of the baseball and softball sphere according to the positioning of the fixture. The appearance directly reflects the unique appearance of the baseball and softball, that is, the baseball and softball of the present invention or the second-generation skinned softball developed. This baseball and softball maintains the appearance effect and functional effect of traditional baseball and softball, and has various properties of traditional baseball and softball in terms of bounce force, impact resistance, pressure resistance, and deformation resistance, thereby reducing production costs and improving production capacity. The mass production of equipment has replaced the current situation of difficult manual work.

In the above, for the core:

The ball core can be used with various weights, circumferences, pressure resistance coefficients and COR (Coefficient of Restitution) ball cores required by customers, such as rubber cores, PU cores, PVC cores, wood cores or different materials (such as rubber, PU). , PVC or more) mixed cores, or cores wound with multiple layers of wool, cotton or threads of different materials (such as wool and cotton), as the cores that need to be wrapped by the wrapping layer.

For ball skins:

The ball skin is made of genuine leather or artificial leather to match the circumference and surface area of the core, and is designed to cut a cardboard cutting die, and then cut the ball skin by a cutting machine.

The choice of ball leather material can be traditional genuine leather or artificial leather (such as PVC leather), such as pigskin, cowhide, PU leather, PVC leather, TPU leather. The selection of the ball skin material should also be based on the overall combination of the core and the collar to achieve the weight and circumference, weight and combination of the core circumference to meet the requirements of the baseball softball (the second generation of the skinned softball) after the finished product. selected. After the ball skin is selected, the cardboard is cut according to the surface area and circumference of the ball core. After trying to fit the body, a knife mold is made.

The processing method of the ball skin is to make the corresponding cardboard and knife mold according to the surface area and circumference of the ball core for different ball cores and different machine pressures. Then a cutting machine is used to carry out the blanking process of the ball skin to form a suitable ball skin. The ball skin (one or two or more pieces of ball skin) cut by the cutting machine is directly glued to the core by the process of mass production of the equipment.

For the jersey:

The jersey includes a core and a skin that wraps the core. For the jersey can be obtained in two ways:

One embodiment is as described above, after applying the glue to the ball skin and the ball core respectively, put them into the well-aligned mold together, and through appropriate temperature and pressure, the ball skin and the ball core are fused. Forms a jersey after gluing.

Another embodiment is obtained by one-shot molding. It can directly use the material formula for producing artificial leather, and the prepared leather material puree can be obtained by directly wrapping the core of the leather through a mold for one-time molding; it is also possible to make the once-molded leather puree fill the mold cavity through inflow and dispersion. , and then high temperature molding, curing and drying after demoulding, tightly wrapping and attaching to the core to form a one-time molding jersey. The inner part of the jersey does not contain an adhesive layer, which simplifies the production process;

The other embodiment omits the process link of cutting the whole leather to the alignment and bonding, that is, directly generating the ball skin on the ball core to obtain the ball core, thereby further simplifying the production process. The jersey obtained in this other embodiment also simplifies the internal structure of the baseball and softball of the first embodiment, so that the inside of the jersey does not contain an adhesive layer.

On the one hand, the shape of the jersey (that is, the shape of the ball skin) can be matched with the stitched collar to produce a jersey skin with a toothed edge shape. The collar height and line distance have a cross-matching effect. After the ball skin is attached to the core, there will be a hollow line collar position on the ball skin. Apply directly to the core to create the overall appearance.

On the other hand, the appearance of the jersey can also be a jersey outer skin with arc-shaped lines. Appearance shape.

For glue:

Adhesive, which plays the role of effectively bonding, fusing or engaging the core and the skin, and the skin and the thread collar with the effect of sewing thread collar. The composition and material of the adhesive are selected according to the matching of the core and the ball skin and the ball skin and the line collar. For example, when the glued material is PU ball skin and PU ball. When the core is selected, polyurethane glue (the composition contains polymers with urethane group and isocyanate group, diethyl silicone oil and triethylene diamine); when the glue is cowhide and is wound with TR wire When the core of the ball is selected, the resin glue (containing natural rubber, softening oil, antioxidant and DM (ie dibenzothiazole disulfide)) is selected, and the glue is selected according to the material matching of different glued materials. This choice results in a stronger bond between the core and the skin, and between the skin and the thread collar with a stitched collar effect.

Adhesive formulations can be adjusted for different adhesives.

The formula can be adjusted according to the requirements of the weather, the dosage ratio and the material change, so as to achieve the standard requirements of hardness and bounce such as good molding, less bubbles, yellowing resistance, and anti-aging.

For line collars:

The stitched collar strips include rubber-plastic strips or fiber strips. When the rubber-plastic material is PU material, a PU infusion machine is used to infuse the mold engraved with the baseball and softball suture collar; when the rubber-plastic material is PVC, TPU Or EVA material, the injection molding machine is used to inject the mold with the baseball and softball stitching collar; the fiber material collar is made of natural fiber or artificial fiber fiber stitch line after fiber twisting and weaving. A thread collar with the appearance of a baseball and softball stitching collar is formed, and then the fiber thread collar is pasted on the corresponding stitching collar position of the ball skin.

For fit method:

1. For the bonding of the core and the skin, as well as the skin and the suture collar, the core and the skin are placed together in a mold with a foreskin function for alignment, and the skin is wrapped with glue to fit the ball The core is formed into a ball skin that wraps the ball core, and then the glue is applied to the position corresponding to the stitching line collar on the ball skin, and the suture line collar is aligned and fitted on the corresponding position of the ball skin, and then let stand bonding.

2. Or place it in another mold or fixture, and then take it out after bonding and processing with a ball press equipped with a suction device.

Specifically, adjust the most suitable threshold temperature and pressure for the ball press according to different materials, and then use the suction device to accurately adsorb the ball skin on the mold according to the position of the mold fixture, and then accurately measure the ball core. Fit in place so that the skin is firmly bonded to the core. Similarly, the stitched ball thread collar is also adsorbed on the mold through the suction device, and then the ball skin is accurately aligned and fitted. In the above process, the ball press can also be adjusted to an appropriate threshold low temperature, so that the ball skin and the ball core, the stitched ball collar and the ball skin are respectively statically engaged through the adhesive.

3. Or the line collar and the ball skin with the hollow design of the line collar are simultaneously adsorbed on the mold by the suction device according to the position of the mold fixture, and then the ball core is accurately adsorbed. Position fit or static bonding, so that the ball skin and the line collar are firmly bonded to the ball core through the glue at the same time.

The first method can be simply referred to as the sequential lamination method without the suction device, the second can be simply referred to as the sequential lamination method with the suction device; the third method can be simply referred to as the simultaneous lamination device with the suction device. The first and second fitting methods can correspond to the shape of the jersey as an arc-shaped line edge shape; the third type can correspond to the shape of the jersey with a toothed edge shape, that is, a ball with a hollow design at the line collar Skin.
