Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a ball core grinding device. Background Art

[0002] The core refers to the core part of the ball.

[0003] In the prior art, the core of a golf ball needs to be ground before use to remove burrs from its surface. This process is usually performed using a grinder. Multiple sets of cores are poured directly into the grinder, which then drives the cores to rotate at high speed inside the grinder, using centrifugal force to grind the cores against the rough inner wall of the grinder.

[0004] However, when pouring several golf ball cores into the grinder, since the golf ball cores are made of rubber and have great elasticity, they will collide with the bottom of the grinder and rebound, causing the ball cores to fly out of the grinder. The violent collision may even cause the ball cores to break, affecting the subsequent grinding work. Utility Model Content

[0024] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] For the purpose of simplicity and illustration, the principles of the embodiments are described primarily with reference to examples. In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring the understanding of these embodiments. In addition, all embodiments may be used in combination with each other.

[0026] See also Figures 1 to 6 , the utility model provides a technical solution: a ball core grinding device.

[0027] In the first embodiment, a conduit 5 is provided inside the grinding machine body 1. Since the diameter of the conduit groove 13 is slightly larger than the ball core, the ball core will squeeze the air in the conduit groove 13 when it falls downward. Since the ball core is constantly falling, the air at the lower end of the conduit groove 13 has no time to be squeezed out, so it will support the ball core falling from above and slightly slow down the ball core. A baffle 12 is provided on the inner wall of the conduit 5 near the port. When the ball core falls onto the surface of the baffle 12, due to the falling of the ball core and its own force, the ball core knocks the baffle 12 open, causing a second deceleration of the ball core. A traction plate 6 is fixed to the end of the conduit 5, and the traction plate 6 is at a certain angle to the port of the conduit 5.

[0028] A first spring 10 is fixed to the surface of the inclined plate 11, and a push plate 9 is fixed to the end of the first spring 10. A push plate 9 is provided above the traction plate 6, and the first spring 10 is supported at the rear of the push plate 9, so the ball core rolling on the traction plate 6 will push the push plate 9 away and continue to roll, and the elasticity of the first spring 10 is very weak, so it will not clamp the ball core, which has a three-fold deceleration effect on the ball core. A vertical plate 8 is fixed to the end of the inclined plate 11, and a traction rod 7 is fixed to the surface of the vertical plate 8. Since the distance between the traction rods 7 is slightly larger than the diameter of the ball core, the contact surface between the traction rod 7 and the ball core is very close to the axis of the ball core, so the ball core that rolls onto the traction rod 7 will rotate on the traction rod 7 and slowly move forward and fall into the bottom of the grinder body 1, so that the falling force of the ball core is converted into a rotational force, which has a four-fold deceleration effect on the ball core.

[0029] On the basis of Example 1, in order to prevent the ball core from violently colliding with the inner wall of the grinder body 1, a cap 2 is provided at the end of the grinder body 1. A curved surface 3 is provided on the upper surface of the cap 2. The curved surface 3 is funnel-shaped. When several ball cores are poured into the curved surface 3 of the cap 2, the ball cores will fall into the conduit groove 13 one by one. A through hole 4 is provided in the center of the curved surface 3. The through hole 4 corresponds to and is fixed to the conduit 5. A conduit groove 13 is provided inside the conduit 5.

[0030] A mounting groove 14 is provided on the inner wall of the conduit groove 13 near the port, a connecting ring 15 is fixed on the inner wall of the mounting groove 14, a second spring 17 is sleeved on the outer surface of the connecting ring 15, due to the presence of the second spring 17, the baffle 12 that has been knocked open will immediately reset after the ball core leaves, a connecting sleeve 16 is sleeved on the outer surface of the second spring 17, a sleeve groove 18 is provided inside the connecting sleeve 16, a baffle 12 is fixed on the inner surface of the connecting sleeve 16, and the ball core falls onto the surface of the baffle 12. Due to the fall of the ball core and its own force, the ball core knocks the baffle 12 open, causing a secondary deceleration of the ball core.

[0031] The connecting ring 15 is fixed to the inner wall of the connection between the mounting groove 14 and the catheter groove 13. The radius of the baffle 12 is the same as the depth of the mounting groove 14. A traction plate 6 is fixed to the lower end of the catheter 5. The traction plate 6 is at a certain angle to the axis of the catheter 5, and the traction plate 6 will not block the mounting groove 14.

[0032] An inclined plate 11 is fixed on the outer surface of the catheter 5. The inclined plate 11, the push plate 9 and the traction plate 6 are distributed in parallel. The distance between the push plate 9 and the traction plate 6 is smaller. Multiple groups of first springs 10 are fixed between the push plate 9 and the inclined plate 11. The elasticity of the first spring 10 is very weak, so it will not clamp the ball core.

[0033] The distance between the push plate 9 and the traction plate 6 is slightly smaller than the diameter of the ball core, and the diameter of the catheter groove 13 is slightly larger than the diameter of the ball core. The ball core rolling on the traction plate 6 will push the push plate 9 away and continue to roll, which will slow down the ball core three times. A vertical plate 8 is fixed to the end of the inclined plate 11. The vertical plate 8 is parallel to the axis of the catheter 5, and a traction rod 7 is fixed to the surface of the vertical plate 8.

[0034] There are two groups of traction rods 7, which are symmetrically distributed. The distance between the two groups of traction rods 7 is slightly larger than the diameter of the ball core. Since the distance between the traction rods 7 is slightly larger than the diameter of the ball core, the contact surface between the traction rods 7 and the ball core is very close to the axis of the ball core. Therefore, the ball core rolling onto the traction rods 7 will rotate on the traction rods 7 and slowly move forward and fall to the bottom of the grinder body 1, so that the falling force of the ball core is converted into a rotational force, which has a four-fold deceleration effect on the ball core.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
