Description

Technical Field

[0001] This utility model relates to the technical field of steel ball sorting equipment, and in particular to a non-destructive steel ball sorting device. Background Technology

[0002] Steel balls, as a fundamental industrial component, have wide and crucial applications in many fields. In the bearing manufacturing industry, steel balls are the core rolling elements of bearings. Their quality and dimensional accuracy directly determine the bearing's operating performance, service life, and load-bearing capacity. Defects or dimensional deviations can lead to serious safety accidents, affecting equipment performance and safety. Therefore, steel balls need to be screened.

[0003] Currently, among existing steel ball screening equipment, such as the patent with authorization announcement number CN210411555U, this utility model relates to the technical field of steel ball processing equipment, specifically a steel ball finished product sorting machine, including a steel ball box, a screening box, a roller screening box, a finished product box and a waste box. The steel ball box is located on the outside of the screening box, and both the steel ball box and the screening box are set at an inclination. A discharge port is opened on the bottom side of the steel ball box, and the discharge port penetrates through the top side wall of the screening box and extends into the interior of the screening box. The interior of the screening box is equipped with a first screen.

[0004] However, during the use of the equipment, it was found that the flow control of the steel balls was not very convenient, which could easily lead to a large number of steel balls being screened at once, reducing the screening effect and increasing the mutual wear and collision of the steel balls during the screening process, thus reducing the protection effect on the steel balls. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a non-destructive steel ball sorting device that avoids increased collision damage between a large number of steel balls, reduces the collision intensity between steel balls and between steel balls and the tank, and improves the non-destructive sorting effect of steel balls.

[0006] This utility model discloses a non-destructive steel ball sorting device, comprising a storage box and a discharge channel, the discharge channel being connected to the lower part of the outer wall of the storage box; it also includes a collecting device, a control device, a trough, a trapezoidal plate, and multiple sorting holes. The trough is located below the discharge channel and is inclined to the right, with two sets of discharge outlets on it. The trapezoidal plate is installed in the middle of the inner wall of the trough, and the multiple sorting holes are all located on the outer wall of the trapezoidal plate. The trapezoidal plate communicates with the first set of discharge outlets of the trough. The collecting device is located at the second set of discharge outlets and is used to decelerate and collect the sieved steel balls. The control device is located at the opening of the discharge channel and is used to control the number of steel balls discharged. The steel balls to be sorted are placed into the storage box. In the storage tank, steel balls flow into the discharge channel. A control device opens the discharge channel, allowing a precise amount of steel balls to be discharged into the tank, preventing collision damage between large numbers of balls. The steel balls roll to the right along the inclined angle of the tank, contacting the surface of a trapezoidal plate. The inclination of the trapezoidal plate guides the rolling flow of the steel balls. During this process, the steel balls pass through multiple sorting holes, where small, defective balls are sorted. These sorted balls are stored inside the trapezoidal plate. The steel balls then continue rolling to the collection device, where their rolling speed is reduced, decreasing the collision intensity between the balls and with the tank before collection. This process improves the effectiveness of non-damaging steel ball sorting.

[0007] Preferably, the control device includes a cover plate, a connector, a motor, a turntable, and a connecting arm. The cover plate is rotatably mounted on the outer wall of the discharge channel via the connector and is positioned at the opening of the discharge channel. The motor is mounted on the outer wall of the discharge channel, and the turntable is positioned on the motor output end. The bottom end of the connecting arm is rotatably mounted on the outer wall of the turntable at an eccentric position, and the top end of the connecting arm is rotatably connected to the upper part of the outer wall of the cover plate. The motor drives the turntable to rotate, which in turn drives the cover plate to rotate via the connecting arm. This allows the cover plate to open the discharge channel opening via the guide support of the connector, improving the convenience of controlling the discharge of steel balls in the discharge channel. The motor drives the turntable to rotate continuously, facilitating the reciprocating closing of the cover plate via motor control, thus improving the convenience of automatic quantitative discharge of steel balls.

[0008] Preferably, the collection device includes a speed bump, a guide platform, and a first sealing door. The speed bump is located at the bottom of the inner wall of the tank, the guide platform is located on the right side of the inner wall of the tank, and the first sealing door is installed at the second set of outlets of the tank. The steel balls rolling on the tank flow through multiple sets of speed bumps, which slow down the movement of the steel balls. Then, the guide platform collects the steel balls, improving the convenience of steel ball collection and reducing impact damage between steel balls. By opening the first sealing door, the convenience of steel ball discharge is improved.

[0009] Preferably, it also includes a second sealing door, which is located at the first set of outlets of the tank; by opening the second sealing door, the convenience of discharging the steel balls sorted in the trapezoidal plate is improved.

[0010] Preferably, it also includes a first guide channel and a second guide channel, both of which are installed on the outer wall of the tank body. The first guide channel is located at the second set of discharge outlets, and the second guide channel is located at the first set of discharge outlets; this improves the convenience of post-discharge guiding and conveying of the steel balls.

[0011] Preferably, it also includes a guide plate, which is installed on the inner side wall of the tank; the guide plate guides and transports the steel balls discharged from the discharge channel, improving the convenience of sorting the steel balls through the multi-group sorting holes.

[0012] Preferably, it also includes a buffer pad, which is disposed on the inner side wall of the tank and below the opening of the discharge channel; the steel balls discharged from the discharge channel fall onto the buffer pad, and the buffer pad cushions the steel balls, reducing the impact damage from the falling steel balls.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The steel balls to be sorted are placed inside the storage box, and the steel balls in the storage box flow into the discharge channel. The opening of the discharge channel is opened by the control device, so that the steel balls are quantitatively discharged into the tank, avoiding increased collision damage between a large number of steel balls. The steel balls roll to the right through the tilt angle of the tank and come into contact with the surface of the trapezoidal plate. The tilt angle of the trapezoidal plate guides the rolling flow of the steel balls. During the guidance process, the steel balls pass between multiple sorting holes, and the small-sized unqualified steel balls are sorted through the multiple sorting holes. The sorted steel balls are stored inside the trapezoidal plate. Then the steel balls on the tank continue to roll to the collection device. The collection device slows down the rolling speed of the steel balls, thereby reducing the collision intensity between steel balls and between the steel balls and the tank. Then they are collected, improving the effect of non-damaging sorting of steel balls. Attached Figure Description

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, this utility model discloses a non-destructive steel ball sorting device, including a storage box 1 and a discharge channel 2. The discharge channel 2 is connected to the lower part of the outer wall of the storage box 1. It also includes a collecting device, a control device, a trough 3, a trapezoidal plate 4, and multiple sorting holes 6. The trough 3 is located below the discharge channel 2 and is inclined to the right. The trough 3 is provided with two sets of discharge outlets. The trapezoidal plate 4 is installed in the middle of the inner wall of the trough 3. The multiple sorting holes 6 are all located on the outer wall of the trapezoidal plate 4. The trapezoidal plate 4 is connected to the first set of discharge outlets of the trough 3. The collecting device is located at the second set of discharge outlets. The collecting device is used to decelerate and collect the screened steel balls. The control device is located at the opening of the discharge channel 2 and is used to control the number of steel balls discharged.

[0023] like Figure 4 As shown, the control device includes a cover plate 6, a connector 7, a motor 8, a turntable 9, and a connecting arm 10. The cover plate 6 is rotatably mounted on the outer wall of the discharge channel 2 via the connector 7, and the cover plate 6 is located at the opening of the discharge channel 2. The motor 8 is mounted on the outer wall of the discharge channel 2, the turntable 9 is located on the output end of the motor 8, the bottom end of the connecting arm 10 is rotatably mounted on the outer wall of the turntable 9 at an eccentric position, and the top end of the connecting arm 10 is rotatably connected to the upper part of the outer wall of the cover plate 6.

[0024] In this embodiment, the steel balls to be sorted are placed inside the storage box 1. The steel balls in the storage box 1 flow into the discharge channel 2. The opening of the discharge channel 2 is opened by the control device, so that the steel balls are quantitatively discharged into the tank 3, avoiding increased collision damage between a large number of steel balls. The steel balls roll to the right through the tilt angle of the tank 3 and come into contact with the surface of the trapezoidal plate 4. The tilt angle of the trapezoidal plate 4 guides the rolling flow of the steel balls. During the guidance process, the steel balls pass between the multi-group sorting holes 6. The multi-group sorting holes 6 sort out the small-sized unqualified steel balls. The sorted steel balls are stored inside the trapezoidal plate 4. Then, the steel balls on the tank 3 continue to roll to the collection device. The collection device slows down the rolling speed of the steel balls, thereby reducing the collision intensity between the steel balls and with the tank 3. Then they are collected, improving the effect of non-damaging sorting of steel balls.

[0030] like Figure 5 As shown, it also includes a buffer pad 18, which is disposed on the inner side wall of the tank 3 and below the opening of the discharge channel 2.

[0031] In this embodiment, the turntable 9 is driven to rotate by the motor 8, which in turn drives the cover plate 6 to rotate via the connecting arm 10. This allows the cover plate 6 to open the discharge channel 2 through the guide support of the connecting piece 7, improving the convenience of controlling the discharge of steel balls in the discharge channel 2. The turntable 9 is continuously rotated by the motor 8, which facilitates the reciprocating closing of the cover plate 6 by the motor 8, improving the convenience of automatic quantitative discharge of steel balls. The steel balls rolling on the trough 3 flow through multiple sets of deceleration belts 11, which block the steel balls and slow them down. Then, the steel balls are collected by the guide platform 12, improving the convenience of steel ball collection and reducing impact damage between steel balls. By opening the first sealing door 13, the convenience of steel ball discharge is improved.

[0032] This utility model discloses a non-destructive steel ball sorting device. During operation, the steel balls to be sorted are placed inside a storage box 1. The steel balls in the storage box 1 flow into a discharge channel 2. A control device opens the discharge channel 2, allowing the steel balls to be quantitatively discharged into a trough 3. The steel balls roll to the right at the inclination angle of the trough 3, contacting the surface of a trapezoidal plate 4. The inclination angle of the trapezoidal plate 4 guides the rolling flow of the steel balls. During this flow, the steel balls pass between multiple sorting holes 6, where small-sized, non-compliant steel balls are sorted. The sorted steel balls are stored inside the trapezoidal plate 4. Subsequently, the steel balls on the trough 3 continue to roll to a collection device.

[0033] The motor 8 of the non-destructive steel ball sorting device of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
