[0038] refer to Figure 1-4 As shown, the utility model provides an automatic ball feeding device for billiard ball polishing, comprising a drum mechanism 4, a ball entry tube 6, a polishing tube 7, a tray 3 and a ball-moving mechanism 5;

[0039] The rotating drum mechanism 4 includes a bottom ring 44, an inner cylinder 41, a side cover plate 43 and an outer cylinder 42. The inner cylinder 41 and the outer cylinder 42 are concentrically arranged on the bottom ring 44. An annular channel is formed between the inner cylinder 41 and the outer cylinder 42 for the passage of billiard balls. The rotating drum mechanism 4 is connected to a driving mechanism 10. In some embodiments, the driving mechanism 10 can be configured to be electrically driven or manually driven.

[0040] The ball tubes 6 are multiple and are annularly inserted on the outer periphery of the outer cylinder 42. Figure 6 As shown, a ball outlet notch 61 is provided at the bottom end of the ball tube 6. The bottom end of the ball tube 6 contacts the inner tube 41 but does not penetrate the inner tube 41. Preferably, four ball tubes 6 are provided in this embodiment, and the ball outlet notch 61 is located in the annular channel.

[0041] The polishing tubes 7 are multiple and annularly arranged on the outer periphery of the outer cylinder 42. The polishing tubes 7 and the goal tubes 6 are staggered. The upper end of the polishing tube 7 is provided with a cover 8. The lower end of the polishing tube 7 passes through the side wall of the outer cylinder 42 and the side wall of the inner cylinder 41 in sequence. The lower end of the polishing tube 7 extends into the inner cylinder 41 by 4-6 cm. Figure 7As shown, the polishing tube 7 is provided with a goal hole 71. It is worth noting that the position of the goal hole 71 is below the polishing tube 7 and is not connected to the bottom end of the polishing tube 7, while the position of the ball outlet notch 61 is connected to the bottom end of the goal tube 6. In addition, the length of the goal tube 6 needs to be greater than the length of the polishing tube 7, so that when the drum mechanism 4 rotates, the circular diameter swept by the goal tube 6 is greater than the circular diameter swept by the polishing tube 7. Only in this way, when the drum mechanism 4 rotates, the goal tube 6 can touch the volleyball mechanism 5 while the polishing tube 7 cannot touch the volleyball mechanism 5. The goal hole 71 is located in the annular channel and the goal hole 71 and the ball outlet notch 61 are opposite to each other, so that when the drum mechanism 4 rotates, the billiard ball can enter and exit from the goal hole 71 and the ball outlet notch 61. A counterweight mechanism 15 for applying pressure to the billiard ball is provided in the polishing tube 7, so as to apply a certain pressure to the billiard ball during polishing;

[0042] The tray 3 is arranged above the drum mechanism 4 and is provided with a ball outlet channel 31 on the tray 3. The ball outlet channel 31 and the tray 3 can be slightly tilted to facilitate the sliding of billiard balls, and the width of the ball outlet channel 31 should be set to meet the requirement that only a single row of billiard balls can pass through. The bottom surface of the ball outlet channel 31 is provided with a ball drop port 32 and strip holes 33. A ball-moving volleying mechanism 5 is rotatably provided below the ball drop port 32. The billiard balls in the front will pass through the ball drop port 32 and fall onto the ball-moving volleying mechanism 5 for temporary storage.

[0043] refer to Figure 5 As shown, the volleyball-moving mechanism 5 includes a supporting rotating plate 51, a rotating arm 54 and a rear baffle 52. The rotating arm 54 is arranged on both sides of the supporting rotating plate 51. The rotating arm 54 and the supporting rotating plate 51 are an integral structure. Preferably, the upper edge of the supporting rotating plate 51 has an arc-shaped notch to increase the contact surface with the temporarily stored billiard balls, and the rotating arm 54 is rotatably connected to both sides of the ball outlet channel 31. The rear baffle 52 is arranged on the rear side of the supporting rotating plate 51 and the end of the rear baffle 52 is located in the bar hole 33.

[0044] A further solution for the volleyball mechanism 5 is that a torsion spring 55 is provided at the rotating fulcrum of the rotating arm 54, so that the supporting rotating plate 51 needs to apply a certain force to rotate, thereby avoiding the easy swing of the supporting rotating plate 51. When the torsion spring 55 is in the initial state, the supporting rotating plate 51 is perpendicular to the center line of the ball landing port 32 and the rear baffle 52 does not extend from the bottom surface of the ball outlet channel 31. A front baffle 53 is provided on the front side of the supporting rotating plate 51, so that when the billiard ball falls on the supporting rotating plate 51, the front baffle 53 can further block the billiard ball.

[0045] The device further comprises a bracket 1 , a drum mechanism 4 is rotatably arranged on the bracket 1 , a tray 3 is arranged above the bracket 1 , a receiving pan 2 is further placed on the bracket, and the receiving pan 2 is located below the drum mechanism 4 .

[0046] When the goal tube 6 rotates to the 6 o'clock position, the billiard balls are discharged from the goal tube 6 and fall onto the receiving plate 2 to collect the polished billiard balls;

[0047] A turntable bearing base 12 is provided on the outside of the outer cylinder 42. The turntable bearing base 12 can be a dining table turntable bearing base. A support frame 13 is provided on the bracket 1. The support frame 4 can be welded to the bracket 1. The outer ring of the turntable bearing base 12 is fixedly provided on the inner side of the support frame 13. In addition, the outer ring of the turntable bearing base 9 and the support frame 4 can be connected by welding or screws to ensure the smooth rotation of the outer cylinder 42. The outer periphery of the outer cylinder 42 is also provided with a clamp fixing buckle 9 for fastening to the ball tube 6 and the polishing tube 7.

[0048] A limit ring 16 is also provided in the annular channel. The limit ring 16 is located on both sides of the goal tube 6, thereby limiting the movement path of the billiard ball, so as to facilitate guiding the billiard ball to enter and exit from the goal hole 71 and the ball outlet notch 61. A side cover plate 43 for covering the limit ring 16 is also fixedly provided at the end of the outer tube 42.

[0049] In order to drive the drum mechanism 4 to rotate, the present application provides two implementations:

[0050] The first is manual drive, specifically, the driving mechanism 10 is a handle, which is arranged at the center of the side cover 43. With this arrangement, the drum mechanism 4 can be driven to rotate by simply turning the handle;

[0051] The second type is electric drive. Specifically, the driving mechanism 10 includes a rotating shaft 104, a drum motor 102, a driving gear 101 and a driven gear 103. The rotating shaft 104 is provided at the center of the side cover 43, and the driven gear 103 is provided on the rotating shaft 104. A bearing seat 11 and a drum motor 102 are provided on the bracket 1. The rotating shaft 104 is passed through the bearing seat 11. A driving gear 101 is provided at the output end of the drum motor 102, and the driving gear 101 and the driven gear 103 are engaged. In this method, the drum mechanism 4 is driven to rotate by the drum motor 102. Since polishing takes a certain amount of time, the drum motor 102 cannot use a high-speed motor. In the present utility model, the drum motor 102 is a servo motor, a speed-regulating motor or a stepping motor. The servo motor has the characteristics of low speed and adjustable speed, and the stepping motor has the characteristics of intermittent rotation. Through this, the drum mechanism 4 can be rotated slowly or intermittently, thereby reserving sufficient time for polishing.

[0052] The inner wall of the polishing tube 7 is provided with a plurality of wool strips 14 , and the wool strips 14 are located below the ball hole 71 .

[0053] Furthermore, the number of wool strips 14 is 6-8 and is pasted on the inner wall of the polishing tube 7. Figure 8As shown, the counterweight mechanism 15 includes a support 152, a screw 153, a wool pad 151 and a guide plate 154. The wool pad 151 is arranged on the bottom surface of the support 152 and can be connected by pasting. The screw 153 is connected above the support 152 and the guide plate 154 is connected to the screw 153. The diameters of the guide plate 154 and the support 152 are 2-5 mm smaller than the inner diameter of the polishing tube 7. In addition, the height of the entire counterweight mechanism 15 needs to be greater than the diameter of the polishing tube 7.

[0054] This allows the support 182 to slightly shake in the polishing tube 7 to fine-tune the rotation of the billiard ball. In addition, a wool pad 151 is provided on the bottom surface of the support 152 and a wool strip 14 is provided on the inner wall of the polishing tube 7, so that when the billiard ball contacts it, the billiard ball is rotated by means of friction, thereby preventing the billiard ball from only having linear contact with the polishing wheel 13 and affecting the polishing effect.

[0055] The working principle of the present invention is that the billiard balls are placed in the tray 3, and the billiard balls follow the slope from the ball outlet channel 31 into the ball drop port 32 and fall onto the supporting rotating plate 51 for temporary storage. The drum mechanism 4 rotates under the drive of the driving mechanism 10. During the rotation, the ball tube 6 touches the supporting rotating plate 51 and rotates it. The billiard balls temporarily stored on the supporting rotating plate 51 fall into the ball tube 6. At the same time as the supporting rotating plate 51, the rear baffle 52 extends from the bar hole 33 to block the next ball from entering the ball drop port 32, so as to prevent multiple balls from entering the same ball tube 6. After the ball tube 6 rotates away from the supporting rotating plate 51, the supporting rotating plate 51 is reset, the rear baffle 52 is retracted, and the next ball continues to fall into the ball drop port 32. Figure 9 As shown, after the billiard ball enters the goal tube 6, it is discharged from the ball outlet notch 61 through the annular channel and enters the polishing tube 7 from the goal hole 71. When the polishing tube 7 rotates to the 12 o'clock position, the billiard ball falls onto the polishing wheel for polishing due to the gravity of the billiard ball and the pressure applied by the counterweight mechanism 18. When the polishing tube 7 rotates to the 9 o'clock position, the billiard ball enters the goal tube 6 from the goal hole 71 again, and then the billiard ball falls from the goal tube 6 onto the receiving tray 2 to collect the polished billiard balls.

[0056] Although the present invention has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and implementations may be devised by those skilled in the art that fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications may be made to the components or arrangements of the subject combination arrangement within the scope of the present disclosure, the drawings, and the claims. In addition to variations and modifications to the components or arrangements, other uses will also be apparent to those skilled in the art.
