Description

Technical Field

[0001] This application relates to the field of ball grinding equipment, and in particular to a ball grinding machine. Background Technology

[0002] After the inner core of the ball is formed, its surface needs to be polished in order to facilitate the subsequent processing and production of finished balls (basketballs, footballs, volleyballs, rugby balls, etc.).

[0003] Taking a basketball as an example, a basketball consists of an inner tire layer, a yarn layer, a mid-tire layer, and an outer skin layer from the inside out. In order to improve the firmness of the outer skin layer attached to the mid-tire layer, the surface of the mid-tire layer usually needs to be sanded before the outer skin layer is glued to the surface of the mid-tire layer.

[0004] The existing methods for grinding inner tubes usually involve manual grinding with a hand-held grinding rod or by holding the inner tube close to the grinding disc, which is inefficient. To improve grinding efficiency, grinding machines have gradually emerged. However, the grinding quality of existing grinding machines is not ideal. For example, one existing grinding machine includes a support frame and a grinding cylinder set on the support frame. The top of the grinding cylinder has a feed port, and the bottom of the grinding cylinder has a grinding platform and a drive mechanism for rotating the grinding platform. The upper surface of the grinding platform has several grinding trays evenly distributed for grinding the surface of the basketball inner tube. The grinding trays include grinding steel wires.

[0005] In the above scheme, several balls are fed into the inside of the grinding cylinder through the feed port. The grinding platform is driven by the drive mechanism to rotate multiple grinding trays, which in turn cause several intermediate balls to tumble inside the grinding cylinder. The tumbling intermediate balls are then ground by the grinding wires set on the grinding trays, thereby improving the grinding efficiency of the balls. However, due to its structure, it is easy for the surface of the balls to be ground unevenly, or even for the balls to be punctured, thus affecting the grinding quality. Summary of the Invention

[0006] In order to improve the grinding quality while ensuring grinding efficiency, this application provides a ball grinding machine.

[0007] The ball grinding machine provided in this application adopts the following technical solution: A ball grinding machine, comprising:

[0008] frame;

[0009] A grinding device is provided on the frame; the grinding device includes a support, a grinding component and a pressing component, the grinding component and the pressing component cooperate to grind the ball placed on the support;

[0010] The grinding assembly includes a grinding component and a first motor. The grinding component is located on one side of the support and can contact the surface of the ball placed on the support. The first motor drives the grinding component to rotate, thereby causing the ball on the support to rotate.

[0011] The pressing assembly includes a driving component and a pressing wheel. The pressing wheel is located above the support seat. The driving component is used to drive the pressing wheel to reciprocate and press the ball so that part of the ball's surface is intermittently pressed against the grinding workpiece, while reducing the rotational speed of the ball.

[0012] A ball-rotating device, which is mounted on the frame;

[0013] The ball-rotating device includes a ball-rotating assembly, a drive source, and a pusher. The ball-rotating assembly is used to grasp or support the ball, and the pusher drives the ball-rotating assembly to move closer to or away from the ball on the support seat. The drive source drives the ball-rotating assembly to change the grinding angle of the ball.

[0014] By adopting the above technical solution, the ball located on the support contacts the grinding part. The first motor drives the grinding part to rotate, thereby causing the ball to rotate. At the same time, the pressing component drives the pressing wheel to intermittently press against the ball through the driving component, so that the surface of the ball intermittently adheres to the grinding part. During the pressing process, the rotation speed of the ball is lower than that of the grinding part. The grinding part, together with the pressing component, simulates manual grinding to grind part of the circumferential surface of the ball. After the circumferential surface of the ball is ground, the ball rotating device works. The pushing component pushes the ball rotating component close to the ball, so that the ball rotating component can grasp the ball. After grasping, the driving source drives the ball rotating component to rotate to change the grinding angle of the ball. Then the ball rotating component releases the ball and moves away from the support under the drive of the pushing component, returning to its original position. Then the grinding device grinds the surface of the ball again. This process is repeated many times, so that the entire surface of the ball is ground, improving the uniformity of the ball surface grinding. Compared with manual grinding, the grinding efficiency is improved, and the grinding quality is improved by simulating manual grinding.

[0015] Preferably, it further includes a mounting frame, wherein the pressing component and the rotating ball component are both disposed on the mounting frame, the pushing component is mounted on the frame, and the output shaft of the pushing component is fixedly connected to the mounting frame; the pressing component and the rotating ball component are both located above the support seat, and the pushing component drives the pressing component and the rotating ball component to a pressing position and a gripping position close to the support seat.

[0016] By adopting the above technical solution, the pressing component and the rotating ball component on the drive mounting bracket are brought close to the support seat. When the ball is being ground, the pressing component drives the pressing wheel to reciprocate pressing the ball through the drive component. At this time, the rotating ball component does not work. When it is necessary to change the angle of the ball, the pressing component does not work, and the rotating ball component works to grab the ball, thereby facilitating the pressing or grabbing of the ball on the support seat.

[0017] Preferably, the ball-rotating assembly includes a first clamping roller, a second clamping roller, a sliding block, and a driving source. The first clamping roller is vertically rotatably connected to the mounting frame. At least two second clamping rollers are provided, and the two second clamping rollers are vertically spaced and rotatably connected to the sliding block. The sliding block is slidably connected to the mounting frame. The driving source is located on the mounting frame, and the output end of the driving source is connected to the sliding block for pushing the sliding block to move the second clamping rollers toward the direction of the first clamping roller. The driving source is located on the mounting frame and drives the first clamping roller to rotate.

[0018] By adopting the above technical solution, the pusher drives the mounting frame to move the ball assembly downward, so that the ball is located in the gripping position between the first and second gripping rollers. The pusher drives the sliding block to move the two second gripping rollers toward the first gripping roller, thereby gripping and fixing the ball between the first and second gripping rollers. Then, the driveer drives the first gripping roller to rotate, thereby causing the ball located between the first and second gripping rollers to rotate by an angle, thus facilitating the switching of the ball angle.

[0019] Preferably, the ball-rotating assembly includes a suction cup and a hollow shaft. The hollow shaft is fixedly connected to the suction cup and rotatably connected to the mounting bracket. The hollow shaft is connected to a vacuum generator through a pipeline. The drive source drives the hollow shaft to rotate. The suction cup is located above the support.

[0020] By adopting the above technical solution, the pusher drives the mounting bracket to move the suction cup down to contact the surface of the ball. The vacuum generator creates negative pressure on the suction cup to adsorb the ball. Then, the drive source drives the hollow shaft to rotate, thereby causing the suction cup to rotate the ball, which facilitates the switching of the ball's angle.

[0021] Preferably, the ball-rotating assembly includes an upper lifting seat, and the pushing member is fixedly disposed on the support seat; the driving source is fixedly disposed on the output shaft of the pushing member, and the upper lifting seat is horizontally mounted on the output shaft of the driving source to drive the upper lifting seat to rotate; the pushing member drives the upper lifting seat to move upward so that the upper lifting seat supports the ball; or the pushing member drives the upper lifting seat to move downward so that the support seat supports the ball.

[0022] By adopting the above technical solution, when it is necessary to change the grinding angle of the ball on the support, the pusher drives the drive source to move the lifting seat upward to contact the bottom of the ball, thereby transferring the ball on the support to the lifting seat. Then, the drive source drives the lifting seat to rotate, thus facilitating the switching of the ball angle.

[0023] Preferably, multiple grinding components, support seats, pressing components, and rotating ball components are provided, and the grinding components and support seats are spaced apart on the frame; the pressing components and rotating ball components are spaced apart on the mounting frame; the frame is rotatably connected to a synchronous shaft, and multiple grinding components are coaxially spaced on the synchronous shaft, and the first motor drives the synchronous shaft to rotate;

[0024] It also includes a connecting rod, which is fixedly connected to multiple sliding blocks, and the output shaft of the push source is fixedly connected to one of the sliding blocks;

[0025] It also includes a synchronous drive assembly, which includes a driving gear, multiple driven gears and a chain. The driving gear is coaxially fixed on the output shaft of the drive component, the driven gears are coaxially fixedly connected to the first clamping roller, and the chain meshes with both the driving gear and the driven gear.

[0026] By adopting the above technical solution, multiple grinding components, support seats, pressing components, and rotating ball components are provided. The first motor drives the synchronous shaft to rotate, thereby synchronously driving multiple grinding components to grind multiple balls located on the support seats. In conjunction with multiple pressing components, multiple balls are ground, thereby improving the grinding efficiency of the balls and reducing the number and cost of the first motor. The rotating ball component fixes multiple sliding blocks together through connecting rods, thereby synchronously driving multiple sliding blocks to move the second clamping rollers synchronously through the push source, thereby synchronously clamping multiple balls, thus reducing the number and cost of the push source. At the same time, the drive component drives the drive gear to rotate, and the drive gear drives multiple driven gears to rotate synchronously through the chain, thereby synchronously driving multiple first clamping rollers to rotate, thereby synchronously rotating and switching angles of multiple balls, reducing the number and cost of the push component.

[0027] Preferably, multiple grinding components, support seats, pressing components, and rotating ball components are provided, and the grinding components and support seats are spaced apart on the frame; the pressing components and rotating ball components are spaced apart on the mounting frame; the frame is rotatably connected to a synchronous shaft, and multiple grinding components are coaxially spaced on the synchronous shaft, and the first motor drives the synchronous shaft to rotate;

[0028] It also includes a synchronous drive assembly, which includes a driving gear, multiple driven gears and a chain. The driving gear is coaxially fixed on the output shaft of the drive component, the driven gears are coaxially connected to the hollow shaft, and the chain meshes with both the driving gear and the driven gear.

[0029] By adopting the above technical solution, multiple grinding parts, support seats, pressing components, and rotating ball components are provided. The first motor drives the synchronous shaft to rotate, thereby synchronously driving multiple grinding parts to grind multiple balls located on the support seat. In conjunction with multiple pressing components, multiple balls are ground, thereby improving the grinding efficiency of the balls and reducing the number and cost of the first motor. The rotating ball component drives the drive gear to rotate through the drive component. The drive gear drives multiple driven gears to rotate synchronously through the chain, thereby synchronously driving multiple hollow shafts to rotate. This allows multiple balls to rotate and switch angles synchronously, thereby reducing the number and cost of the drive component.

[0030] Preferably, the support includes a base, a support roller, and two limiting wheels. The base is fixedly mounted on the frame. The support roller is rotatably connected to the base, and the rotation axis of the support roller is parallel to the rotation axis of the grinding workpiece. The two limiting wheels are rotatably connected to the base at intervals, and the two limiting wheels are located at the two ends of the support roller. The opposing wheel surfaces of the two limiting wheels are outwardly convex arc surfaces, and the rotation axis of the limiting wheels is parallel to the rotation axis of the support roller.

[0031] By adopting the above technical solution, since the ball is elastic, during the rotation of the ball driven by the grinding component on the support seat, the support roller and the limiting wheel set on the support seat cooperate with the pressure component to make the support roller and the limiting wheel rotate synchronously with the ball, thereby reducing the occurrence of bouncing during the rotation of the ball; at the same time, the limiting wheel set on the arc surface at both ends of the support roller can limit the ball between the two limiting wheels, thereby reducing the occurrence of ball rotation deviation, improving the stability of ball rotation, and thus improving the quality of ball grinding.

[0032] Preferably, the grinding component is a grinding roller brush, which is arranged in an arc shape with concave ends towards the middle.

[0033] By adopting the above technical solution, the grinding roller brush is set in an arc shape with the center concave inward, thereby increasing the contact area between the grinding roller brush and the surface of the ball, and thus improving the grinding efficiency of the grinding roller brush.

[0034] Preferably, the pressing assembly further includes a bracket, the pressing wheel is rotatably connected to the bracket, at least three pressing wheels are provided, the at least three pressing wheels are at the same height but not on the same straight line, and the rotation axis of the pressing wheel is parallel to the rotation axis of the grinding part.

[0035] By adopting the above technical solution, with at least three pressure rollers not on the same straight line pressing against the surface of the ball, the stability of the pressure assembly pressing against the rotation of the ball can be improved, and the occurrence of ball deviation can be reduced.

[0036] Preferably, it further includes a movable seat, a horizontal push cylinder, and a receiving channel. The movable seat is slidably connected to the frame, the pusher is mounted on the movable seat, and the output shaft of the pusher is fixedly connected to the mounting frame. The horizontal push cylinder is horizontally mounted on the frame, and the output shaft of the horizontal push cylinder is fixedly connected to the movable seat to push the rotating ball assembly to be located above the support seat or above the receiving channel.

[0037] By adopting the above technical solution, after the ball is polished, the flat-push cylinder drives the moving seat to move the ball rotating assembly above the support seat. The pusher drives the mounting frame to move the ball rotating assembly close to grab the ball. Then, the pusher drives the ball rotating assembly to move the ball upward. Then, the flat-push cylinder drives the ball rotating assembly to be above the receiving channel. Then, the pusher drives the ball rotating assembly to move downward. The ball rotating assembly releases the ball on the receiving channel, thus facilitating the collection of the polished ball.

[0038] Preferably, it further includes an auxiliary roller brush, which is rotatably connected to the frame. A second motor is mounted on the frame, and the second motor drives the auxiliary roller brush to rotate. The support is located between the auxiliary roller brush and the grinding part, and the rotation axis of the auxiliary roller brush is parallel to the rotation axis of the grinding part.

[0039] By adopting the above technical solution, and by setting an auxiliary roller brush on the side of the support away from the grinding workpiece, the grinding efficiency of the ball is improved.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] The grinding disc assembly drives the ball to rotate along the horizontal diameter direction parallel to the grinding workpiece, and in conjunction with the pressing assembly, grinds the circumferential surface of the ball on the support. Then, the rotating ball assembly grabs or supports the ball, and the drive source drives the ball to rotate along the vertical diameter direction to switch angles. The cooperation between the grinding device and the rotating ball device covers the surface of the ball, thereby improving the quality and efficiency of ball grinding. Attached Figure Description

[0052] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0053] Example 1: This application discloses a ball grinding machine. (Refer to...) Figure 1 and Figure 2 This ball grinding machine is used to grind the surface of a ball. This embodiment uses the inner tire of a basketball as an example; however, it is understood that the ball grinding machine disclosed in this application can also be applied to other types of balls and is not limited thereto. The ball grinding machine includes a frame 1, an electrical control box 2, a grinding device 3, and a ball rotating device 4. The frame 1 is enclosed by plates to form a casing, and the grinding device 3 and the ball rotating device 4 are installed inside the casing. The electrical control box 2 is located on one side of the casing and is used to control the operation of the grinding device 3 and the ball rotating device 4. The grinding device 3 is used to grind part of the circumferential surface of the inner tire ball. The ball rotating device 4 is used to rotate and switch the ball's angle. The grinding device 3 and the ball rotating device 4 cooperate to change the grinding angle of the ball, so as to evenly grind the surface of the ball.

[0054] Specifically, refer to Figure 2 The grinding device 3 includes a support 31, a grinding component 32, and a pressing component 33. The support 31 is mounted on the frame 1 and is used to support the ball. The grinding component 32 and the pressing component 33 cooperate to grind the ball on the support 31 in the circumferential direction.

[0055] Reference Figure 3 In this embodiment, the grinding assembly 32 includes a grinding element 321 and a first motor 322. The grinding element 321 is horizontally rotatably mounted on the frame 1 and located on one side of the support 31. The surface of the ball on the support 31 can contact the grinding element 321. The first motor 322 is mounted on the frame 1 and is used to drive the grinding element 321 to rotate, thereby causing the ball on the support 31 to rotate. Preferably, the grinding element 321 in this embodiment is a grinding roller brush. The grinding roller brush includes a roller shaft 3211 and bristles 3212 fixed on the roller shaft 3211. In order to increase the contact area between the grinding roller brush and the surface of the ball, the surface of the grinding roller brush is concave from both ends to the middle in an arc. In other embodiments, the grinding element 321 can also be a grinding wheel or a grinding belt.

[0056] In this embodiment, the support base 31 includes a support 311, a support roller 312, and two limiting wheels 313. The support 311 is fixedly mounted on the frame 1. The support roller 312 is rotatably connected to the support 311, and the rotation axis of the support roller 312 is parallel to the rotation axis of the grinding part 321. The two limiting wheels 313 are rotatably connected to the support 311 at intervals, and the two limiting wheels 313 are located at both ends of the support roller 312. The opposing wheel surfaces of the two limiting wheels 313 are both outwardly convex arc surfaces, and the rotation axis of the limiting wheels 313 is parallel to the rotation axis of the support roller 312, and the rotation axes of the two limiting wheels 313 are higher than the rotation axis of the support roller 312.

[0057] Reference Figure 2 and Figure 4 A mounting frame 11 is horizontally provided inside the frame 1, located above the support base 31. The pressing component 33 is mounted on the mounting frame 11. In this embodiment, the pressing component 33 includes a driving member 331, a bracket 332, and a pressing wheel 333. The driving member 331 is mounted on the mounting frame 11, the bracket 332 is fixedly mounted on the output shaft of the driving member 331, and the pressing wheel 333 is rotatably connected to the bracket 332.

[0058] Furthermore, at least three pressure rollers 333 are provided. These three pressure rollers 333 are at the same height but not aligned on the same straight line, and their rotation axes are parallel to the rotation axis of the grinding component 321. The presence of at least three pressure rollers 333, not aligned on the same straight line, pressing against the surface of the ball improves the stability of the pressure assembly 33 in pressing against the rotation of the ball and reduces the occurrence of ball deviation.

[0059] Preferably, in this embodiment, four pressure rollers 333 are provided, and the four pressure rollers are arranged in a rectangular shape above the support 31. Specifically, the pressure assembly includes two pressure rollers 333, which are rotatably connected to the bracket 332. Two pressure assemblies 33 are provided, and the two pressure assemblies 33 are installed on both sides of the mounting frame 11 to achieve a rectangular distribution of the four pressure rollers 333. In other embodiments, the pressure rollers 333 may be provided in a number greater than three, which is not limited here.

[0060] In this embodiment, the driving component 331 is a cylinder. The extension and retraction of the cylinder's output shaft can be easily controlled via the electrical control box 2, thereby adapting to and pressing against balls of different diameters. In other embodiments, the driving component 331 can also be driven by a motor in conjunction with a lead screw.

[0061] Because the ball in the intermediate tube is elastic, during the rotation of the ball driven by the grinding roller brush on the support 31, the support roller 312 and the limiting wheel 313 set on the support 311 rotate in conjunction with the pressing wheel 333 in the pressing assembly 33, so that the support roller 312 and the limiting wheel 313 follow the rotation of the ball, thereby reducing the occurrence of bouncing during the rotation of the ball; at the same time, the limiting wheel 313 set on the arc surface at both ends of the support roller 312 can limit the ball between the two limiting wheels 313, thereby reducing the occurrence of ball rotation deviation, improving the stability of ball rotation, and thus improving the quality of ball grinding.

[0062] Reference Figure 3 and Figure 4 To improve the grinding efficiency of the spheres, multiple support seats 31, grinding components 32, and pressing components 33 are provided. Multiple support seats 31 and grinding components 32 are spaced apart within the frame 1, and multiple pressing components 33 are spaced apart on the mounting bracket 11, corresponding to the support seats 31. The frame 1 is horizontally rotatably connected to a synchronous shaft 323. Multiple grinding components 321 are coaxially spaced on the synchronous shaft 323. A first motor 322 drives the synchronous shaft 323 to rotate via a reducer and a pulley. Therefore, multiple grinding rollers are synchronously driven by a single first motor 322, thereby reducing equipment costs. In this embodiment, three support seats 31, grinding components 32, and pressing components 33 are provided.

[0063] The grinding process and principle of the grinding device 3: The first motor 322 drives the grinding roller brush to rotate, which in turn drives the ball located on the support 31 to rotate along the horizontal diameter direction. At the same time, the driving component 331 in the pressing component 33 above the support 31 drives the pressing wheel 333 to intermittently press against the surface of the ball. Since the ball has elasticity, the surface of the ball is intermittently pressed against the grinding roller brush. During the pressing process, the rotation speed of the ball decreases, so the grinding roller brush grinds the surface of the ball along the circumferential direction, simulating the way of manually holding the ball to grind, thereby improving the grinding efficiency and quality of the ball.

[0064] Since the grinding device 3 drives the intermediate tire ball to rotate around the horizontal diameter direction as the rotation axis for grinding, it is necessary to use the ball rotating device 4 to rotate around the vertical diameter direction of the ball to switch the ball angle before grinding, so as to grind the surface of the intermediate tire ball evenly and improve the grinding quality of the intermediate tire ball.

[0065] Reference Figure 5 and Figure 6Specifically, the ball-rotating device 4 includes a ball-rotating assembly 41, a drive source 42, and a pusher 43. The ball-rotating assembly 41 is mounted on the mounting frame 11 and is used to grip the ball. The pusher 43 is set on the frame 1, and the output shaft of the pusher 43 is fixedly connected to the mounting frame 11. The pusher 43 drives the pressing assembly 33 and the ball-rotating assembly 41 to the pressing position and gripping position near the support seat 31.

[0066] The drive source 42 is mounted on the mounting frame 11 and is used to drive the ball rotating assembly 41 to rotate the ball horizontally by an angle. In this embodiment, the pusher 43 is a cylinder, and two cylinders are provided. The two cylinders are vertically spaced on the frame 1, and the output shafts of the two cylinders are fixedly connected to the mounting frame 11, thereby improving the stability of driving the mounting frame 11 to move up and down.

[0067] The ball-rotating assembly 41 in this embodiment includes a first clamping roller 411, a second clamping roller 412, a sliding block 413, and a driving source 414. The first clamping roller 411 is vertically rotatably connected to the bottom of the mounting frame 11. The sliding block 413 is horizontally slidably connected to the bottom of the mounting frame 11 via a guide rail, and the sliding direction of the sliding block 413 is towards or away from the first clamping roller 411. At least two second clamping rollers 412 are provided, and the two second clamping rollers 412 are vertically spaced and rotatably connected to the sliding block 413. The first clamping roller 411 and the second clamping roller 412 are parallel to each other, and the first clamping roller 411 and the two second clamping rollers 412 are arranged in a triangle. The driving source 414 is mounted on the mounting frame 11, and the output end of the driving source 414 is connected to the sliding block 413 to drive the second clamping roller 412 to move closer to the first clamping roller 411 to clamp the ball or to move away from the first clamping roller 411 to release the ball. The driving source 42 drives the first clamping roller 411 to rotate.

[0068] The pusher 43 drives the mounting bracket 11 to move the first clamping roller 411 and the second clamping roller 412 downward, so that the ball is located in the gripping position between the first clamping roller 411 and the second clamping roller 412. The pusher 414 drives the sliding block 413 to move the two second clamping rollers 412 toward the first clamping roller 411, thereby clamping the ball between the first clamping roller 411 and the second clamping roller 412. Then the pusher 43 drives the first clamping roller 411 and the second clamping roller 412 to move upward, thereby gripping the ball. Then the driveer 42 drives the first clamping roller 411 to rotate, thereby causing the ball to rotate and switch angles.

[0069] Multiple ball-rotating assemblies 41 are provided, spaced apart along the length of the mounting frame 11 and corresponding to the support 31 below. A connecting rod 415 is also included, which is fixedly connected to multiple sliding blocks 413. In this embodiment, two connecting rods 415 are provided, arranged parallel and spaced apart. The driving source 414 in this embodiment is a cylinder, mounted at one end of the mounting frame 11. The cylinder's output shaft is fixedly connected to a nearby sliding block 413 via a fixing block 4141, used to synchronously drive the multiple sliding blocks 413 to move. In other embodiments, the driving source 414 can also be a motor coupled with a lead screw to drive the sliding blocks 413 to move.

[0070] Furthermore, to improve the stability of the ball clamping, a fixing ring 416 is fixedly sleeved on the connecting rod 415, and a spring 417 is movably sleeved on the connecting rod 415. One end of the spring 417 abuts against the fixing ring 416, and the other end abuts against the sliding block 413. Due to the different inflation amounts of the balls, the diameters of the balls vary. Through the elastic force of the spring 417 on the connecting rod 415, there is room for variation in the clamping distance between the second clamping roller 412 and the first clamping roller 411, thereby adapting to clamping balls of a certain diameter.

[0071] It also includes a synchronous drive assembly 44, through which the drive source 42 synchronously drives multiple first clamping rollers 411 to rotate. Specifically, the synchronous drive assembly 44 includes a driving gear 441, multiple driven gears 442, and a chain 443. The driving gear 441 is coaxially and fixedly connected to the output shaft of the drive source 42, the driven gears 442 are coaxially and fixedly connected to the first clamping rollers 411, and the chain 443 meshes with both the driving gear 441 and the driven gears 442. By synchronously driving multiple first clamping rollers 411 to rotate through a single drive source 42, the equipment cost is reduced.

[0072] In this embodiment, the drive source 42 is a motor, which facilitates installation and control of the ball's rotation angle. In other embodiments, the drive source 42 can also be a cylinder in conjunction with a rack and pinion to drive the drive gear 441 to rotate.

[0073] Reference Figure 6 It also includes a movable base 12, a horizontal push cylinder 13, and a receiving rack 14. The receiving rack 14 is fixedly installed on the frame 1, located on the side of the grinding roller brush and extending out of the frame 1 at one end. The receiving rack 14 forms a receiving channel 141 with an upper opening, which is inclined downward towards the end of the frame 1 at the extension. The movable base 12 is slidably connected to the frame 1 via a guide rail, and a pusher 43 is installed on the movable base 12. The horizontal push cylinder 13 is horizontally installed on the frame 1, and its output shaft is fixedly connected to the movable base 12 to push the rotating ball assembly 41 to be located above the support 31 or above the receiving channel 141.

[0074] After the ball is polished, the flat-push cylinder 13 drives the moving seat 12 to move the ball rotating assembly 41 above the support seat 31. The pusher 43 drives the mounting bracket 11 to move the ball rotating assembly 41 close to grab the ball. Then, the pusher 43 drives the ball rotating assembly 41 to move the ball upward. Then, the flat-push cylinder 13 drives the ball rotating assembly 41 to be above the receiving channel 141. Then, the pusher 43 drives the ball rotating assembly 41 to move downward. The ball rotating assembly 41 releases the ball onto the receiving channel 141, thus facilitating the collection of the polished ball.

[0075] It also includes a support tray 5 with an upper opening. The support tray 5 is installed on the frame 1 and is located below the grinding assembly 32. It is used to collect the debris from the grinding of the ball. A collection pipe 51 is connected to the bottom of the support tray 5.

[0076] Reference Figure 6 and Figure 7 It also includes a ball-releasing rack 15 and a ball-collecting rack 16. The ball-releasing rack 15 is installed on the outside of the frame 1, and a ball-releasing channel 151 is formed inside the ball-releasing rack 15. A ball-releasing outlet 152 is provided at one end of the ball-releasing rack 15. Multiple ball-collecting racks 16 are provided, and the multiple ball-collecting racks 16 are spaced apart along the length direction of the ball-releasing rack 15. The ball-releasing rack 15 extends into the inside of the frame 1. The ball-collecting rack 16 forms a ball-collecting channel 161, which is connected to the ball-releasing channel 151. The ball-exit outlet of the ball-collecting channel 161 is lower than the ball-collecting outlet of the ball-collecting channel 161, and the ball-exit outlet of the ball-collecting channel 161 is located above one side of the grinding assembly 32.

[0077] The frame 1 is equipped with a ball-blocking assembly 17, which is used to prevent the ball from entering the ball-scoring channel 161 from the ball-collecting channel 151. Specifically, the ball-blocking assembly 17 includes a blocking rod 171 and a blocking cylinder 172. The blocking cylinder 172 is vertically mounted on the frame 1, and its output shaft is fixedly connected to the blocking rod 171. The blocking rod 171 is horizontally positioned, and the blocking cylinder 172 drives the blocking rod 171 to a blocking position between the ball-collecting channel 151 and the ball-scoring channel 161, or to move it upwards to a ball-collecting position where the ball-collecting opening of the ball-collecting channel 161 is opened.

[0078] The ball placement rack 15 is equipped with a ball pushing assembly 18, which is used to push the ball towards the goal-scoring channel 161. The ball pushing assembly 18 includes a push rod 181 and a ball pushing cylinder 182. The ball pushing cylinder 182 is vertically installed on the outside of the ball placement rack 15. The push rod 181 is located on the output shaft of the ball pushing cylinder 182. The ball pushing cylinder 182 can push the push rod 181 into the ball placement channel 151, thereby pushing the ball in the ball placement channel 151 towards the goal-scoring channel 161.

[0079] Reference Figure 6 and Figure 7 The system also includes an auxiliary roller brush 324 and a guide roller 19, which are rotatably connected to the frame 1. A second motor 325 is mounted on the frame 1, and the second motor 325 synchronously drives the auxiliary roller brush 324 and the guide roller 19 to rotate via a chain and sprocket. The guide roller 19 is located above the auxiliary roller brush 324. The ball outlet of the ball inlet channel 161 is close to the guide roller 19 to guide the ball into the support seat 31. The support seat 31 is located between the auxiliary roller brush 324 and the grinding element 321, and the rotation axis of the auxiliary roller brush 324 is parallel to the rotation axis of the grinding element 321. The auxiliary roller brush 324 assists in grinding the ball, improving the efficiency of ball grinding.

[0080] Multiple balls are sequentially fed into the ball release channel 151 through the ball release port 152 of the ball release rack 15. The balls in the ball release channel 151 are arranged in sequence. The partition cylinder 172 drives the partition rod 171 to move upward, thereby opening the ball inlet of the ball inlet channel 161. The push cylinder 182 drives the push rod 181 to push the ball in the ball release channel 151 into the ball inlet channel 161. The ball rolls along the ball inlet channel 161 to the guide roller 19, and then rolls onto the support seat 31, thereby automatically placing the ball in the ball release channel 151 onto the support seat 31.

[0081] The implementation principle of a ball grinding machine according to an embodiment of this application is as follows: the ball located on the ball rack 15 automatically falls onto the support 31 through the cooperation of the ball blocking assembly 17 and the ball pushing assembly 18. The grinding assembly 32 drives the ball to rotate around the horizontal diameter axis. With the cooperation of the pressing assembly 33, the circumferential surface of the ball on the support 31 is ground. Then, the pushing member 43 and the ball rotating assembly 41 cooperate to grab the ball. The driving source 42 drives the ball to rotate around the vertical diameter axis to switch the angle. Through the cooperation of the grinding device 3 and the ball rotating device 4, the grinding is carried out, thereby improving the quality and efficiency of ball grinding.

[0082] Example 2: Refer to Figure 8 The difference from Embodiment 1 lies in the structure of the rotating ball assembly 41. In this embodiment, the rotating ball assembly 41 includes a suction cup 451 and a hollow shaft 452. The lower end of the hollow shaft 452 is fixedly connected to the suction cup 451, and the hollow shaft 452 is rotatably connected to the mounting bracket 11. The upper end of the hollow shaft 452 is connected to a vacuum generator through a pipeline. The drive source 42 drives the hollow shaft 452 to rotate. The suction cup 451 is located above the support 31 and is situated in the upper part between the four pressure rollers 333.

[0083] Two splines 453 are fixedly provided on the driven gear 442. A hollow shaft 452 is vertically slidably connected to the driven gear 442. A vertical groove 454 is opened on the side wall of the hollow shaft 452 in the vertical direction, and the splines 453 are slidably connected to the vertical groove 454. A push cylinder 455 is vertically mounted on the mounting bracket 11. A connecting block 456 is horizontally fixed to the output shaft of the push cylinder 455, and the connecting block 456 is fixedly connected to the hollow shaft 452. Since the suction cup 451 is located between the four pressure rollers 333, the push cylinder 455 drives the suction cup 451 to move up and down, so that the suction cup 451 adheres to the ball and is either adsorbed or avoids the upper part between the four pressure rollers 333, so that the pressure rollers 333 press against the ball.

[0084] The implementation principle of a ball grinding machine according to an embodiment of this application is as follows: the pusher 43 drives the mounting frame 11 to move the ball rotating assembly 41 and the pressing assembly 33 downwards and close to the ball. The hollow shaft 452 is moved downwards by the pusher cylinder 455, causing the suction cup 451 to contact the surface of the ball. Then, the vacuum generator causes the suction cup 451 to generate negative pressure and adsorb the ball onto the suction cup 451. Then, the pusher 43 drives the suction cup 451 to move the ball upwards. Then, the drive source 42 drives the suction cup 451 to rotate, thereby completing the switching of the ball angle.

[0085] Example 3: Reference Figure 9 The difference from Embodiment 1 lies in the implementation of the ball-rotating device 4, which is mounted on the support 31. Specifically, in this embodiment, the support 31 includes a base 311 and two limiting wheels 313. The base 311 is fixedly mounted on the frame 1, and the two limiting wheels 313 are rotatably connected to the base 311 at intervals. The opposing wheel surfaces of the two limiting wheels 313 are both outwardly convex arc surfaces, and the rotation axis of the limiting wheels 313 is parallel to the rotation axis of the grinding part 321. The two limiting wheels 313 are used to support the ball.

[0086] In this embodiment, the ball-rotating assembly 41 includes an upper lifting seat 461, a pusher 43 fixedly disposed at the bottom of the support 311, and a drive source 42 fixedly disposed at the pusher 43. The upper lifting seat 461 is horizontally mounted on the drive source 42. In the initial state, the upper lifting seat 461 is located below the two limiting wheels 313. A cylinder drives the upper lifting seat 461 to move upward so that the upper lifting seat 461 supports the ball, or a cylinder drives the upper lifting seat 461 to move downward so that the support seat 31 supports the ball. Preferably, in this embodiment, the pusher 43 is a cylinder, and the drive source 42 is a rotary cylinder.

[0087] The implementation principle of a ball grinding machine according to an embodiment of this application is as follows: when it is necessary to switch the grinding angle of the ball on the support seat 31, the cylinder drives the rotary cylinder to move the lifting seat 461 upward, thereby lifting the ball on the support seat 31 and transferring it to the lifting seat 461. Then, the rotary cylinder drives the lifting seat 461 to rotate, thereby facilitating the switching of the ball angle.

[0088] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
