Description

Technical Field

[0001] This utility model relates to the technical field of billiard ball-spinning equipment, specifically to a ball-spinning machine. Background Technology

[0002] With the continuous improvement of living standards, various leisure and entertainment activities are increasingly favored by the public. Billiards, with its unique charm, has become one of the most popular leisure activities, especially among young people. In traditional billiards, the balls need to be manually rearranged after each game. This process is not only time-consuming and laborious, affecting the smoothness of the game, but also prone to ball loss when the net pockets are worn out, greatly reducing the gaming experience. To solve this problem, the automatic billiard ball rearranger has emerged. This innovative invention will completely change the operating mode of traditional billiards.

[0003] For example, the automatic ball-setting device for billiards disclosed in CN108926834A consists of a lifting section, a transfer section, a ball-retrieving section, and a ball ramp. The lifting section includes a lifting shell, a lifting block, and a rising triangle plate. The transfer section includes a lower insert plate, a lowering block, and a triangular fixing plate. The ball-retrieving section includes a ladder block, a lifting ramp, and a conveyor belt. The ball-retrieving section takes the balls out of each ball rack and places them on the ball ramp. The balls enter the lifting section along the ball ramp, where they are arranged into a triangle. The lifting section then transfers the balls to the transfer section, and the transfer section places the balls on the billiard table.

[0004] However, existing automatic ball-placement devices can only place the billiard balls in a designated position and cannot freely adjust the position of the billiard balls. Therefore, they can only be used in conventional training modes and cannot meet the needs of users for different training content. Utility Model Content

After the billiard ball enters the hole, it will enter the net bag and then enter the receiving pipe under the action of the net bag. Under the action of the conveying screw structure, it will enter the first connecting pipe. As the billiard ball continues to enter the first connecting pipe, the billiard ball in the first connecting pipe will enter the connecting pipe one by one and be transferred to the second connecting pipe under the action of the connecting pipe.

The swing unit can drive the second connecting pipe to rotate independently, so as to drive the entire pendulum tube assembly to move in the horizontal direction, thereby improving the degree of freedom of angle adjustment during pendulum swing and improving pendulum swing efficiency.

[0014] Preferably, the second connecting pipe has an arc-shaped guide protrusion. With the above improvement, as the billiard ball continuously enters the first connecting pipe, the billiard ball falls from the connecting pipe into the second connecting pipe, and is guided by the arc-shaped guide protrusion to roll into the ball-swinging tube assembly, so as to realize the automatic delivery of the billiard ball.

With the above improvements, the billiard ball in the second connecting pipe will enter the first conveying pipe and then enter the second conveying pipe under the action of the conveying screw. It will then enter the extension conveying pipe assembly through the conveying screw, and finally be placed in the designated position on the billiard table through the discharge pipe assembly. The first conveying pipe, the second conveying pipe, and the second connecting pipe work together to achieve multi-angle rotation. The extension conveying pipe assembly can increase the conveying distance, and the discharge pipe assembly can control the ball release, thereby improving the accuracy of billiard ball placement.

[0016] Preferably, the feeding tube assembly includes a drop tube mounted on the extended conveying tube assembly, and a feeding tube rotatably connected to the drop tube.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0030] like Figure 1-6 As shown, a ball-spinning machine includes a mounting base 1, a ball-receiving tube assembly 2 and a ball-spinning tube assembly 3 on the mounting base 1, and the ball-receiving tube assembly 2 can receive billiard balls that enter the pocket of the billiard table and transfer the billiard balls to the ball-spinning tube assembly 3, and place the billiard balls to a designated position through the ball-spinning tube assembly 3.

[0031] Specifically, the ball receiving tube assembly 2 includes a receiving tube 1.1 and a connecting tube 1.2 for connecting the receiving tube 1.1 and the ball pendulum tube assembly 3. The receiving tube 1.1 has a ball inlet 1.3 for the billiard ball to enter, and a ball inlet tube 1.6 is formed on the receiving tube 1.1. The ball inlet 1.3 is formed on the ball inlet tube 1.6. The billiard ball enters the receiving tube 1.1 through the ball inlet tube 1.6. A conveying screw structure 1.4 is provided in the receiving tube 1.1, and the billiard ball is conveyed to the connecting tube 1.2 as the conveying screw structure 1.4 moves. After being guided by the connecting tube 1.2, the billiard ball enters the conveying tube 1.5.

[0032] Alternatively, the ball inlet 1.3 of the receiving tube 1.1 can be set at the highest position. After the billiard ball enters the receiving tube 1.1, it can move directly into the connecting tube 1.2 by gravity.

[0033] Furthermore, the ball-swing tube assembly 3 includes several rotatably connected conveying tubes 1.5, with the initial conveying tube 1.5 rotatably connected to the connecting tube 1.2. A conveying screw structure 1.4 is rotatably installed inside the conveying tube 1.5. By utilizing the multiple rotatably connected conveying tubes 1.5 and working through the conveying screw structure 1.4, the billiard ball is conveyed to the designated position to ensure the accuracy of the billiard ball delivery.

[0034] In addition, the output end of the conveying pipe 1.5 is provided with a billiard ball clamping structure 9.1 for clamping the billiard ball, and the billiard ball clamping structure 9.1 constrains the billiard ball inside the conveying pipe 1.5, or releases the billiard ball from the output end of the conveying pipe 1.5 to the target position on the billiard table.

[0035] During the entire billiards ball swing process, the billiard ball falls from the billiards table into the receiving tube 1.1, and is guided by the connecting tube 1.2 into the conveying tube 1.5. Under the conveying of multiple conveying tubes 1.5, the billiard ball is placed on the designated position on the billiards table, realizing automatic placement of the billiard ball and ensuring the accuracy of the placement. At the same time, the placement position of the billiard ball can be adjusted at will, thereby meeting the different training programs of users.

[0036] Among them, the billiard ball clamping structure 9.1 can not only limit the stability of the billiard ball when it leaves the delivery tube 1.5 to improve the accuracy and stability of the ball placement, but also clamp the billiard ball on the billiard table surface and place it in a designated position for various training purposes.

[0037] In addition, the mounting base 1 is located at the bottom of the billiard table. When the ball-spinning machine is not needed, the ball-spinning tube assembly 3 can be folded up and stored at the bottom of the billiard table, thus hiding the entire ball-spinning machine under the billiard table and avoiding taking up space around the billiard table. This does not affect the normal use of the billiard table and improves the convenience of use.

[0038] As a further explanation of the embodiment of the billiard ball clamping structure 9.1, the billiard ball clamping structure 9.1 includes a control unit 9.2 disposed on both sides of the output end of the delivery pipe 1.5, and a clamping piece 9.3 disposed on the actuating end of the control unit 9.2. The clamping piece 9.3 abuts against the billiard ball to prevent the billiard ball from detaching from the delivery pipe 1.5.

[0039] During use, the billiard balls can also be held by the clamping piece 9.3 to position the billiard balls on the table, thus positioning the billiard balls that have gone into the pocket.

[0040] like Figure 5 As shown in Figure 6, as a further explanation of the specific implementation scheme of the connecting pipe 1.2, the connecting pipe 1.2 includes a first connecting pipe 2.1 connected to the receiving pipe 1.1, a second connecting pipe 2.2 mounted on the mounting base 1, and a connecting pipe 2.3 connecting the first connecting pipe 2.1 and the second connecting pipe 2.2. The output end of the second connecting pipe 2.2 is connected to the conveying pipe 1.5. The first connecting pipe 2.1 is connected to the top of the receiving pipe 1.1, and the connecting pipe 2.3 extends downward. Under the action of the conveying screw structure 1.4, the billiard ball moves upward and enters the first connecting pipe 2.1. As the billiard ball continues to enter, the foremost billiard ball will fall from top to bottom into the second connecting pipe 2.2 and enter the initial conveying pipe 1.5 under the action of gravity acceleration.

[0041] In daily use, a net bag is usually installed at the bottom of the billiard table. After the billiard ball enters the pocket, it enters the net bag and then enters the receiving tube 1.1 under the action of the net bag. Under the action of the conveying screw structure 1.4, it enters the first connecting tube 2.1. As the billiard ball continues to enter the first connecting tube 2.1, the billiard ball in the first connecting tube 2.1 will enter the connecting tube one by one and be transferred to the second connecting tube 2.2 under the action of the connecting tube. Finally, it enters the conveying tube 1.5 through the second connecting tube 2.2 to realize the conveying of the billiard ball.

[0042] Specifically, a support and fixing structure 3.1 is provided on the side of the first connecting pipe 2.1. The support and fixing structure 3.1 includes a fixed support rod 3.2 on one side of the first connecting pipe 2.1, a support seat 3.3 on the other side of the first connecting pipe 2.1, and an adjusting support rod 3.4 inserted into the support seat 3.3. The adjusting support rod 3.4 is threadedly connected to the support seat 3.3. The ball receiving tube assembly 2 needs to be installed at the bottom of the billiard table. The bottom of a conventional billiard table is provided with an installation step. The fixed support rod 3.2 is abutted against the step on one side of the billiard table, and the adjusting support rod 3.4 is abutted against the step on the other side. The adjusting support rod 3.4 cooperates with the support seat 3.3 to make the entire support and fixing structure 3.1 snap into the bottom of the billiard table to realize the installation of the ball receiving tube assembly 2.

[0043] Of course, support seats 3.3 and adjusting support rods 3.4 can be set on both sides of the first connecting tube 2.1, which can also fix the ball receiving tube assembly 2 to the bottom of the billiard table.

[0044] Furthermore, the first connecting pipe 2.1 and the second connecting pipe 2.2 include a connecting pipe body 4.1 and a telescopic pipe body 4.2 that is telescopically disposed within the connecting pipe body 4.1. The connecting pipe body 4.1 is provided with a telescopic unit 4.3, and the actuating end of the telescopic unit 4.3 is connected to an adjusting screw 4.4. The telescopic pipe body 4.2 is provided with a connecting plate 4.5 that is threadedly connected to the adjusting screw 4.4. The telescopic unit 4.3 can drive the adjusting screw 4.4 to rotate, and the connecting plate 4.5 can be threadedly engaged with the adjusting screw 4.4 to quickly adjust the length of the first connecting pipe 2.1 and the second connecting pipe 2.2, greatly improving the convenience of installation.

[0045] The mounting base 1 is equipped with a swing unit 4.6. The actuating end of the swing unit 4.6 is connected to the second connecting pipe 2.2, which is connected to the pendulum tube assembly 3. The connecting pipe 2.3 is fixedly connected to the first connecting pipe 2.1. The first connecting pipe 2.1 is snapped onto the billiard table, and the connecting pipe 2.3 is inserted into the input end of the second connecting pipe 2.2. The swing unit 4.6 can drive the second connecting pipe 2.2 to rotate independently, thereby moving the entire pendulum tube assembly 3 in the horizontal direction, which improves the freedom of angle adjustment during pendulum swing and increases the efficiency of pendulum swing.

[0046] Preferably, the connection between the connecting pipe 2.3 and the first connecting pipe 2.1 is arc-shaped, and the second connecting pipe 2.2 has an arc-shaped guide protrusion 4.7. As the billiard ball continuously enters the first connecting pipe 2.1, the billiard ball falls from the connecting pipe 2.3 into the second connecting pipe 2.2, and is guided by the arc-shaped guide protrusion 4.7 to roll into the ball-swinging tube assembly 3, thereby realizing the automatic delivery of the billiard ball.

[0047] like Figure 2 , Figure 4 As shown, a further explanation of the specific implementation of the conveying pipe 1.5 is provided. The output end of the connecting pipe 1.2 extends horizontally out of the billiard table. The conveying pipe 1.5 includes a first conveying pipe 5.1 that rotates radially along the output end of the connecting pipe 1.2, a second conveying pipe 5.2 that rotates axially on the first conveying pipe 5.1, and an extension conveying pipe assembly 5.3 that is radially mounted on the second conveying pipe 5.2. The extension conveying pipe assembly 5.3 includes a plurality of radially rotatably connected conveying pipes 1.5, and a discharge pipe assembly 5.4 that is radially rotatably connected to the output end of the extension conveying pipe assembly 5.3. The output end of the discharge pipe assembly 5.4 constitutes the ball outlet 5.5.

[0048] Furthermore, the connecting part of the conveying pipe 1.5 is provided with an angle control structure 8.1. The angle control structure 8.1 includes an adjustment unit 8.2 on one conveying pipe 1.5, a drive wheel 8.3 on the output end of the adjustment unit 8.2, and a driven wheel 8.4 on the other conveying pipe 1.5. The drive wheel 8.3 and the driven wheel 8.4 are connected by a transmission. By cooperating with the drive wheel 8.3 and the driven wheel 8.4, the angle of the conveying pipe 1.5 can be adjusted to improve the accuracy of billiard ball placement.

[0049] During the billiards placement process, the billiards from the second connecting pipe 2.2 first enter the first transport pipe 5.1, and then enter the second transport pipe 5.2 under the action of the conveying screw 7.1. Then, through the conveying screw 7.1, they enter the extension transport pipe group 5.3, and finally, through the discharge pipe group 5.4, the billiards are placed in the designated position on the billiard table.

[0050] The first transport pipe 5.1, the second transport pipe 5.2, and the second connecting pipe 2.2 work together to control the multi-angle rotation of the feeding pipe group 5.4. Extending the transport pipe group 5.3 can increase the transport distance, and the feeding pipe group 5.4 can control the ball release, thereby improving the accuracy of the billiard ball placement.

[0051] Furthermore, the feeding tube assembly 5.4 includes a dropping tube 6.1 mounted on the extended conveying tube assembly 5.3, and a feeding tube 6.2 rotatably connected to the dropping tube 6.1. The dropping tube 6.1 forms a ball passage 6.3 connecting the extended conveying tube assembly 5.3 and the feeding tube 6.2. A conveying screw structure 1.4 is mounted inside the extended conveying tube assembly 5.3 and the feeding tube 6.2, which can store multiple billiard balls in the dropping tube 6.1 and control the ball discharge through the feeding tube 6.2 to achieve continuous placement of billiard balls.

[0052] Preferably, a visual inspection lens can be installed on the end of the delivery tube 1.5 to identify the number or color of the ball being placed and to place it at the designated location according to the system settings.

[0053] Preferably, the conveying pipe 1.5 is also equipped with a sensor, so that the conveying screw structure 1.4 will only work when the billiard ball is close to it, thus avoiding jamming.

[0054] Meanwhile, a visual detection camera can be installed on the top of the billiard table to identify the color and position of the billiard balls on the table, as well as the required placement, so as to achieve precise placement of the billiard balls.

[0055] like Figure 3 As shown, as a further explanation of the specific structure of the conveying screw structure 1.4, the conveying screw structure 1.4 includes a drive unit 7.2 and a conveying screw 7.1 connected to the output end of the drive unit 7.2. The conveying screw 7.1 is mounted inside the conveying pipe 1.5. The billiard ball moves under the action of the spiral blades by rotating the conveying screw 7.1.

[0056] Preferably, the axial cross section between the helical blades matches the outer contour of the billiard ball, so that the billiard ball is placed on the conveying screw 7.1, thereby ensuring the stability of the billiard ball during the conveying process.

[0057] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
