Core polishing device for golf ball manufacturing apparatus

The present invention relates to a core grinding device for a golf ball manufacturing apparatus, and can be washed by spraying the washing water to the core and the abrasive stone during the core grinding operation, to prevent the scattering of fine dust, and to recover the washing water after filtering to reuse. In addition, the core in the hopper is not only smoothly supplied to the core alignment portion, but also relates to a core polishing apparatus for a golf ball manufacturing apparatus that can stably support the core when polishing the core.

Usually, the golf ball material is largely composed of natural rubber and plastics. The core is made of a mixture of synthetic rubber and chemicals, the inner layer is made of ionomers and chemicals, and the outer layer is made of Lavalon elastomer, sulfin, or urethane.

The golf ball core is a multi-layered structure made of synthetic rubber and chemicals. A typical golf ball consists of a core and a cover, and is divided into two pieces, three pieces, and four pieces depending on how many layers are made.

Such a golf ball is manufactured as follows.

First, the synthetic rubber and various chemical substances to be mixed are weighed, and approximately 45 kg of synthetic rubber is mixed with 15 kg of chemicals, and the mixed materials are put into a mixer and mixed.

Synthetic rubber and chemicals are mixed and fed into the hopper of the mill. The mixture put into the hopper is mixed once again by kneading by a milling machine.

The mixture kneaded through the mill is fed to the cutter and continuously cut to have a constant width, and the cut mixture is wound on each take-up roll.

The mixture of constant width wound on the take-up roll is fed to the core injection machine, and when the mixture is fed to the core injection machine, the extrusion cylinder of the core injection machine is operated to extrude the supplied mixture to the nozzle side. The mixture extruded from the nozzle is fed to a gate of a core mold consisting of upper and lower molds to extrude the core.

When the core is injected by the core injection machine, the burr around the core is removed through the burr remover, and the core from which the burr is removed is put into the core grinder and polished. The core grinder removes fine burrs around the core and maintains the roundness of the core.

The polished core is fed to the core dryer to dry, and the dried cores are transferred to the cover ejector. When the core is seated on the cover injection mold of the cover injection machine, the cover molten material is extruded to the cover injection mold, and the cover is injection molded around the core.

When the cover is injected around the core, the cover is injected into a vibrating barrel equipped with abrasive stones to remove the burr around the cover, which is washed and dried, and then transferred to a water-soluble primer applicator.

In the water-soluble plasticizer applicator, a primer is applied to the periphery of the cover, the golfer coated with the primer is dried, then transferred to a printing machine, and a character or figure is printed around the golf ball through the printing machine. After finishing printing on the outer surface of the golf ball, urethane is coated around the golf ball.

Core grinding machine of the golf ball manufacturing apparatus of this configuration is a device that removes the fine burr around the core and maintains the roundness of the core since the core is removed and the core is polished as described above.

When the circumference of the core is polished with the abrasive stone of the core polishing machine, fine dust generated in the core is caught in the circumference of the abrasive stone, thereby degrading the function of the abrasive stone.

If the fine dust of the core is pinched in the abrasive stone, the polishing is not performed properly, and thus the fine burr around the core is not properly removed and the roundness of the core is also reduced.
