Description

Technical Field

[0001] This utility model relates to the field of ball-serving machine technology, specifically to a ring-shaped blade ball-clamping mechanism for a ball-serving machine. Background Technology

[0002] The mechanisms used in existing ball-launching machines to control the passage or stopping of balls (such as basketballs, table tennis balls, tennis balls, golf balls, etc.) (such as lever-type baffles, rotary gates, pneumatic valves, etc.) usually have problems such as complex structure, large size, large inertia of moving parts leading to limited response speed, frequent operation causing easy wear and tear, and large impact force on the ball causing easy damage.

[0003] At the same time, especially in application scenarios that require frequent, rapid, and precise control of a single sphere, and demand a compact mechanism, low wear, and sphere-friendly design, existing technical solutions struggle to balance performance, reliability, and size.

[0004] Therefore, a ring-shaped blade ball clamping mechanism for ball-serving machines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a ring-shaped blade ball-clamping mechanism for a ball-serving machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ring-shaped blade ball-clamping mechanism for a ball-serving machine, comprising a bottom ring box, an adjustment mechanism mounted on the bottom ring box, the adjustment mechanism comprising multiple blade bodies, the multiple blade bodies being slidably mounted on the bottom inner wall of the bottom ring box, the inner edges of the multiple blade bodies forming a central through hole, a limiting groove being formed on the bottom side of each of the multiple blade bodies, a multiple limiting pin being fixedly mounted on the bottom inner wall of the bottom ring box, the multiple limiting pins being slidably mounted inside the multiple limiting grooves, a drive mechanism being fixedly mounted on the bottom ring box, a transmission mechanism being mounted on the drive mechanism, and the transmission mechanism being mounted on the blade body.

[0007] Preferably, an L-shaped groove is provided on one side of each of the multiple blade bodies, and an L-shaped slider is fixedly installed on the other side of each of the multiple blade bodies. The L-shaped sliders on two adjacent blade bodies are slidably installed inside the L-shaped groove.

[0008] Preferably, the drive mechanism includes an upper annular box, which is bolted to a lower annular box. A cover plate is bolted to the upper annular box, and an arc-shaped drive box is bolted to the cover plate. A servo motor is bolted to one inner wall of the arc-shaped drive box. A reduction gearbox is connected to the drive shaft of the servo motor. A first spur bevel gear is sleeved on the output shaft of the reduction gearbox. A bearing is fixedly installed on the cover plate, and a transmission shaft is rotatably mounted on the bearing. A second spur bevel gear is sleeved on the upper end of the transmission shaft, and the second spur bevel gear meshes with the first spur bevel gear.

[0009] Preferably, a gear is sleeved on the lower end of the transmission shaft, and an arc-shaped toothed plate meshes with the gear, the arc-shaped toothed plate being fixedly mounted on the transmission mechanism.

[0010] Preferably, the transmission mechanism includes a drive ring, the bottom end of which is rotatably mounted on the cover plate, and the upper end of which is fixedly mounted on the bottom side of the arc-shaped toothed plate. The drive ring has multiple guide holes, and guide shafts are fixedly mounted on multiple blade bodies. The multiple guide shafts are slidably mounted inside the multiple guide holes.

[0011] Preferably, the bottom plate of the cover plate and the top plate of the bottom annular box are provided with positioning holes, and the guide shaft is slidably installed inside the positioning holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model integrates the moving parts tightly in the annular space through the annular layout and radial sliding design, which significantly reduces the overall volume and space occupied by the mechanism, and is particularly suitable for installation in narrow ball conveying pipes.

[0014] (2) This utility model uses lightweight blades, shortens the radial travel distance, and uses a linear sliding motion with low inertia. It is synchronously controlled by a single drive source, which makes the mechanism start and stop extremely quickly and can meet the high-frequency action requirements of high-speed ball launchers for precise control of ball spacing.

[0015] (3) This utility model effectively reduces frictional resistance through the good design of radial sliding friction of the blades; at the same time, the impact of the blades on the ball during the movement is almost zero, avoiding the impact of the reaction force on the mechanism; at the same time, the driving mechanism is subjected to uniform force. These factors work together to greatly reduce the wear of key moving parts and significantly extend the service life and reliability.

[0016] (4) In this utility model, the blade slides outward and the edge of the blade forms an approximately circular through hole. At the same time, by precisely controlling the blade stroke, the size of the through hole can be continuously adjusted to easily adapt to spheres of different diameters.

[0017] (5) This utility model uses a linear sliding and synchronous drive mechanism to make the mechanism operate with low noise and low vibration.

[0018] (6) This utility model achieves absolute synchronization of all blades by using a single drive source, determines the opening and closing positions, has simple control logic, and has high accuracy in repeating actions. Attached Figure Description

[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] Example: Please refer to Figure 1-8 This utility model provides a technical solution: a ring-shaped blade ball-locking mechanism for a ball-serving machine, comprising a bottom ring box 1, an adjustment mechanism mounted on the bottom ring box 1, the adjustment mechanism comprising multiple blade bodies 2, the multiple blade bodies 2 being slidably mounted on the bottom inner wall of the bottom ring box 1, the inner edges of the multiple blade bodies 2 forming a central through hole, each of the multiple blade bodies 2 having a limiting groove 22 on its bottom side, and multiple limiting pins 21 being fixedly mounted on the bottom inner wall of the bottom ring box 1, the multiple limiting pins 21 being slidably mounted inside the multiple limiting grooves 22, and a fixed mechanism on the bottom ring box 1. The drive mechanism is equipped with a transmission mechanism, which is mounted on the blade body 2. Each of the multiple blade bodies 2 has an L-shaped groove 24 on one side and an L-shaped slider 23 fixedly mounted on the other side. The L-shaped sliders 23 on two adjacent blade bodies 2 are slidably installed inside the L-shaped groove 24. By closing the blade bodies 2 in the middle and opening them outwards inside the bottom annular box 1, the obstruction and passage of the sphere can be achieved. At the same time, by using the blade bodies 2 to control the passage and obstruction of different spheres, the flexibility and convenience of this device can be experienced in use.

[0030] Furthermore, the drive mechanism includes an upper annular box 3, which is bolted to the lower annular box 1. A cover plate 31 is bolted to the upper annular box 3, and an arc-shaped drive box 32 is bolted to the cover plate 31. A servo motor 33 is bolted to one inner wall of the arc-shaped drive box 32. A reduction gearbox 34 is connected to the drive shaft of the servo motor 33. A first spur bevel gear 35 is sleeved on the output shaft of the reduction gearbox 34. A bearing 36 is fixedly mounted on the cover plate 31. A drive shaft 37 is rotatably mounted, and a second straight bevel gear 38 is sleeved on the upper end of the drive shaft 37. The second straight bevel gear 38 meshes with the first straight bevel gear 35. A gear 39 is sleeved on the lower end of the drive shaft 37, and an arc-shaped toothed plate 310 meshes on the gear 39. The arc-shaped toothed plate 310 is fixedly mounted on the transmission mechanism. By using a single motor as the driving power source, the blade body 2 can be opened and closed synchronously on the bottom annular box 1, thereby achieving precise control over the passage or obstruction of the sphere.

[0031] Furthermore, the transmission mechanism includes a drive ring 4, the bottom end of which is rotatably mounted on the cover plate 31, and the upper end of which is fixedly mounted on the bottom side of the arc-shaped toothed plate 310. The drive ring 4 has multiple guide holes 41, and multiple blade bodies 2 are fixedly mounted with guide shafts 42. The multiple guide shafts 42 are slidably mounted inside the multiple guide holes 41. The bottom plate of the cover plate 31 and the top plate of the bottom annular box 1 are both provided with positioning holes 43. The guide shafts 42 are slidably mounted inside the positioning holes 43. The arc-shaped toothed plate 310 drives the drive ring 4 to rotate, and the drive ring 4 drives the guide shafts 42 in the guide holes 41 to move. The guide shafts 42 drive the blade bodies 2 to move synchronously towards the center or outward. This not only provides high control precision, but also, through the use of multiple limiting components, it can control the blade bodies 2 to prevent deviation during movement. At the same time, by utilizing the inclined arc setting of the guide holes 41, the radial movement distance of the blade bodies 2 is shorter, and the response speed is faster.

[0032] The working principle is as follows: When the ball does not need to pass through, the switch on the servo motor 33 is activated, which drives the reduction gearbox 34 to rotate. The reduction gearbox 34 drives the first spur bevel gear 35 to rotate, which in turn drives the second spur bevel gear 38 to rotate. The second spur bevel gear 38 drives the transmission shaft 37 in the bearing 36 on the cover plate 31 to rotate, which in turn drives the gear 39 to rotate. The gear 39 drives the arc-shaped toothed plate 310 on the drive ring 4 to rotate within the cover plate 31. The arc-shaped toothed plate 310 drives the drive ring 4 to rotate. At this time, the drive ring 4 rotates, which drives the guide shaft 42 in the guide hole 41 to move. The guide shaft 42 drives the blade body 2 on the limit pin 21 to rotate towards the center within the bottom annular box 1 to form a barrier. When the ball needs to pass through... When passing over the bottom annular box 1, the switch on the servo motor 33 is activated again. The servo motor 33 drives the reduction gearbox 34 to rotate in the opposite direction. The reduction gearbox 34 drives the first straight bevel gear 35 to rotate in the opposite direction. The first straight bevel gear 35 drives the second straight bevel gear 38 to rotate in the opposite direction. The second straight bevel gear 38 drives the transmission shaft 37 to rotate in the opposite direction. The transmission shaft 37 drives the gear 39 to rotate in the opposite direction. The gear 39 drives the arc-shaped toothed plate 310 to rotate in the opposite direction. The arc-shaped toothed plate 310 drives the drive ring 4 to rotate in the opposite direction. The drive ring 4 drives the guide shaft 42 in the guide hole 41 to rotate. The guide shaft 42 drives the blade body 2 in the bottom annular box 1 to slide outward. This allows the assembled blade body 2 to slide outward, exposing the middle passage, which facilitates the passage of the sphere.
