Description

Technical Field

[0001] This utility model relates to the field of ball conveying technology, specifically a ball conveying device. Background Technology

[0002] Balls are an important component of ball bearings. During the ball manufacturing process, they need to be transported and stored using a conveying device.

[0003] For example, the existing utility model patent CN213230473U proposes a ball bearing conveying device for bearing production. This utility model uses the tilting of the bottom of the storage box to automatically gather the balls at the discharge port. The first motor drives the agitator blades on the first rotating shaft to rotate step by step, releasing one ball at a time into the vertical discharge pipe. At the same time, the second motor below the discharge pipe can drive the baffle to open and close intermittently, so that the balls are smoothly sent into the assembly station through the tilted buffer pipe, thereby avoiding blockage and reducing impact.

[0004] As described in the above technical solution, although the baffle installed at the bottom of the vertically arranged discharge pipe can buffer the falling balls, the vertical arrangement of the discharge pipe still causes a significant impact on the baffle when the balls fall, resulting in a reduced baffle life. This leads to the problem of increased costs due to the reduced baffle life. Utility Model Content

[0020] Optionally, the end of the elastic buffer sheet facing the second feed port is arranged in an arc shape that bends upwards.

[0021] Optionally, the conveyor includes a conveyor belt and baffles, wherein,

[0034] Compared with the prior art, the ball conveying device provided by this utility model has the following advantages:

[0035] (1) After the ball is steadily lifted to the first discharge port by the conveyor, the ball immediately enters the buffer cover after leaving the first discharge port. Due to the inclined setting of the buffer cover, the falling ball rolls along the bottom of the buffer cover and is decelerated step by step by the elastic buffer sheet, avoiding the ball from falling vertically, thereby greatly reducing the impact of the ball on the device and improving the service life of the buffer component.

[0036] (2) The elastic buffer plate and the elastic buffer sheet together form a progressive damping channel; the channel gap can be adjusted laterally by the first adjusting component to adapt to different specifications of balls, and the fitting setting of the adjusting plate enhances the strength of the elastic buffer plate itself and further improves its service life; at the same time, the adjusting groove with the arc groove limit is used at the feeding end to realize the angle adjustment of the adjusting groove, so as to avoid the excessive downward force of the balls and damage to the conveying components.

[0037] (3) The drive cylinder drives the detachable closing block to open and close the second feeding port in an instant, so as to realize feeding on demand or emergency shutdown; at the same time, both the closing block and the cylinder are quick-release structures, which shortens the downtime maintenance time and reduces the cost of use.

[0044] 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.

[0045] Please see Figures 1-5 The present application discloses a ball conveying device, which includes a cover 1, a conveying component 2 and a buffer structure 3.

[0046] like Figures 1-4As shown, the cover 1 is inclined upwards, and a first discharge port 101 is opened on the bottom side of the top of the cover 1, and a feed port 102 is opened on the top side of the bottom of the cover 1. The conveying component 2 is located inside the cover 1 and is used to convey the balls to the first discharge port 101. The buffer structure 3 includes a buffer cover 31 and an elastic buffer sheet 32. The buffer cover 31 is inclined at the bottom of the first discharge port 101 and fits against the bottom of the cover 1. A second discharge port 301 is opened at the bottom of the buffer cover 31. The elastic buffer sheet 32 ​​is located inside the buffer cover 31. One end of the elastic buffer sheet 32 ​​is fixed inside the buffer cover 31, and the other end extends toward the second discharge port 301 and approaches the bottom wall of the buffer cover 31 to apply elastic damping to the balls during the sliding process. The end of the elastic buffer sheet 32 ​​facing the second discharge port 301 is arranged in an arc shape that bends upwards.

[0047] Specifically, the cover 1 provides a continuous enclosed channel. After the conveyor 2 lifts the balls to the first discharge port 101, the balls roll along the inner wall of the inclined buffer cover 31 instead of falling vertically. The elastic buffer plate 32 is fixed at its root to the top wall of the buffer cover 31, and its free end first bends upward into an arc shape and then extends downward, forming an elastic arm that "rises first and then falls." The balls first impact the arc-shaped section, changing from point contact to line contact, and the impact force is dispersed. Then, they continue to slide down the inclined surface of the elastic buffer plate 32. The elastic buffer plate 32 is gradually deformed under pressure, applying continuous and increasing elastic resistance to the balls, causing their speed to decrease step by step, and finally rolling out of the second discharge port 301 at low speed. By transforming "vertical impact" into "buffering along the inclined surface," the direct impact of the balls on the device is avoided, and the deformation of the elastic buffer plate 32 is always within the elastic range. The elastic buffer plate 32 is not prone to fatigue fracture, thereby significantly extending the life of the buffer component and reducing maintenance frequency and cost.

[0048] In some embodiments, such as Figure 1 , Figures 3-5 As shown, the buffer structure 3 also includes an elastic buffer plate 33. The elastic buffer plate 33 is inclined and fits against the bottom of the buffer cover 31. One end of the elastic buffer plate 33 faces the second discharge port 301 and extends to the second discharge port 301, so as to form a progressive elastic damping channel for the ball together with the elastic buffer sheet 32.

[0049] Specifically, the elastic buffer plate 33 is laid along the entire length of the bottom wall of the buffer cover 31, forming a wedge-shaped channel that narrows from wide to narrow between it and the elastic buffer sheet 32. After the balls enter the wedge-shaped channel, they continue to decelerate under the dual constraints of the elastic buffer plate 33 and the elastic buffer sheet 32. As the channel gap gradually decreases, the elastic resistance experienced by the balls also gradually increases, achieving "progressive" energy absorption and avoiding excessive force at a single point. At the same time, the progressive damping not only protects the surface of the balls from scratches, but also ensures that the entire buffer structure 3 maintains a stable buffering effect after long-term operation.

[0050] In some embodiments, such as Figure 5As shown, the buffer structure 3 also includes a first fixing plate 34 and a first adjusting member 35. The first fixing plate 34 includes two plates, which are symmetrically arranged on the two side walls of the buffer cover 31 and detachably connected to them. The first adjusting member 35 is arranged between the two first fixing plates 34. The first adjusting member 35 includes an adjusting plate 351, an adjusting column 352 and a fixing column 353. The adjusting plate 351 is arranged at the bottom of the elastic buffer plate 33 and fits against the bottom of the elastic buffer plate 33. The adjusting column 352 is fixedly arranged at the end of the adjusting plate 351 facing the second discharge port 301. The two first fixing plates 34 are respectively provided with limiting grooves 302 for lateral limiting sliding of the adjusting column 352 at both ends. The fixing column 353 is arranged at the end of the adjusting plate 351 away from the second discharge port 301 and abuts against the bottom of the adjusting plate 351. The two ends of the fixing column 353 are respectively fixed on the two first fixing plates 34 to keep the adjusting plate 351 in contact with the elastic buffer plate 33 during the adjustment process.

[0051] Specifically, the adjusting plate 351, supported by the three points of the adjusting column 352 and the fixed column 353, always remains tightly against the elastic buffer plate 33. Loosening the locking mechanism and pushing or pulling the adjusting column 352 allows the adjusting plate 351 to move laterally along the limiting slide groove 302, thereby changing the gap of the wedge-shaped channel. The fixed column 353 acts as a fulcrum to prevent the adjusting plate 351 from being suspended, ensuring that the adjusting plate 351 keeps the elastic buffer plate 33 firmly against it in any position, avoiding localized vibration and wear. This allows for rapid adaptation to different specifications of ball bearings; large ball bearings widen the channel to prevent jamming, while small ball bearings narrow the channel to enhance damping. Furthermore, the entire process requires no disassembly of the buffer cover 31, minimizing maintenance time and simultaneously improving equipment versatility and operational stability.

[0052] In some embodiments, such as Figure 3 As shown, the conveyor 2 includes a conveyor belt 21 and baffles 22. The conveyor belt 21 is inclined upward inside the cover 1 and driven by an external drive structure. The top of the conveyor belt 21 is correspondingly arranged with the first discharge port 101. The baffles 22 include multiple baffles, which are evenly arranged on the outer surface of the conveyor belt 21 and are used to form a conveying groove for conveying balls between the conveyor belt 21 and the inner wall of the cover 1.

[0053] Specifically, the conveyor belt 21 forms a continuous bearing surface inside the housing 1, and the baffle 22 and the inner wall of the housing 1 form a closed channel. The balls are driven by the baffle 22 to rise steadily along the inclined surface. The conveyor belt 21 is driven by an external motor, and its speed is adjustable. The flow rate can be increased or decreased in real time according to the needs of the downstream, avoiding accumulation or material interruption. The conveying channel formed by the baffle 22 and the housing 1 together prevents the balls from slipping during the upward process. At the same time, during the conveying process, rolling friction between the balls is avoided, ensuring the quality of ball conveying.

[0054] In some embodiments, such as Figure 5As shown, it also includes a closing component 4, which includes a second fixing plate 41 and a driving component 42. The second fixing plate 41 includes two plates, which are symmetrically fixed on both sides of the cover 1 at the corresponding second discharge ports 301. The driving component 42 includes two plates, which are respectively disposed on the two second fixing plates 41 and are used to select to close or open the second discharge ports 301. The driving component 42 includes a driving cylinder 421 and a closing block 422. The driving cylinder 421 is detachably disposed on the second fixing plate 41. The closing block 422 is detachably disposed at the driving end of the driving cylinder 421 and is used to drive the cylinder 421 to drive it to close or open the second discharge ports 301.

[0055] Specifically, the drive cylinder 421 is quickly mounted to the second fixed plate 41 via a slot or bolt, and the closing block 422 is threadedly connected to the piston rod and equipped with a locking nut. When the rear buffer box is full or the equipment malfunctions, the external control structure can control the cylinder to extend instantaneously, and the closing block 422 closes the second discharge port 301 in a very short time. The balls are temporarily stored in the buffer cover 31 to prevent overflow. After normal operation is restored, the cylinder retracts, and the discharge port immediately opens, ensuring seamless connection of the feeding cycle. Both the closing block 422 and the cylinder are modular quick-release structures, which can be replaced without tools after wear, greatly reducing downtime maintenance time and significantly improving the overall availability of the machine.

[0056] In some embodiments, such as Figures 1-2 As shown, it also includes a second adjusting component 5, which includes a third fixing plate 51, an adjusting groove 52, and an adjusting shaft 53. The third fixing plate 51 includes two plates, which are symmetrically arranged on both sides of the feed inlet 102 and are detachably connected to the top of the cover 1. The adjusting groove 52 is located between the two third fixing plates 51. One end of the adjusting groove 52 extends into the feed inlet 102, and the other end away from the feed inlet 102 is rotatably connected to the two third fixing plates 51. The adjusting shaft 53 includes two plates, which are rotatably arranged on both sides of the adjusting groove 52 corresponding to the third fixing plates 51. The two third fixing plates 51 are respectively provided with arc-shaped grooves 501 for limiting the sliding of the adjusting shafts 53 at both ends.

[0057] Specifically, the third fixing plate 51 is located at the top of the cover 1 corresponding to the feed inlet 102. The adjusting groove 52 can swing up and down around the rear hinge point. The adjusting shaft 53 moves with the adjusting groove 52 and slides in the arc groove 501 to form a stable guide. When the upstream material drops too fast, the adjusting groove 52 swings upward to reduce the effective cross-sectional area of ​​the feed inlet 102 and reduce the kinetic energy of the ball impacting the conveyor 2. When the flow rate is insufficient, it swings downward to increase the opening and ensure continuous feeding. After the angle is in place, it is fixed by locking with nuts and other workpieces, which not only protects the conveyor 2 from impact but also enables the equipment to quickly adapt to different feeding conditions, further reducing the failure rate and maintenance costs.

[0058] Workflow: The balls enter the housing 1 through the feed inlet 102 from the external feed end. They are first limited and guided by the adjustment groove 52 in the second adjustment component 5, and then fall into the conveying trough composed of the conveyor belt 21 and the baffle 22, and are continuously lifted to the first discharge port 101. After leaving the first discharge port 101, the balls enter the buffer cover 31 and roll along the inclined surface of the bottom wall of the buffer cover 31. They first hit the arc-shaped end of the elastic buffer plate 32 to achieve initial deceleration, and then enter the wedge-shaped progressive damping channel formed by the elastic buffer plate 32 and the elastic buffer plate 33 to continue deceleration. If different specifications of balls need to be adapted, the adjustment plate 351 in the first adjustment component 35 can be changed by sliding it laterally. When the rear buffer is full or the feeding needs to be paused, the drive cylinder 421 drives the closing block 422 to close the second discharge port 301. The balls are temporarily stored in the buffer cover 31. After the closing block 422 is opened, the balls can be discharged from the second discharge port 301.
