Description

Technical Field

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

[0002] During processing, phosphor bronze balls require screening, but existing screening equipment has significant shortcomings. Its automation level is low, feeding relies on manual labor, making it difficult to accurately control the feeding speed and quantity, increasing labor costs and impacting screening efficiency. Furthermore, during screening, the phosphor bronze balls are unevenly dispersed, easily missing or incorrectly screened, resulting in inconsistent sizes after screening. Additionally, the screening apertures are poorly designed, failing to efficiently classify and screen phosphor bronze balls of different sizes, making it difficult to meet the needs of large-scale production. Utility Model Content

[0003] The purpose of this invention is to provide a phosphor bronze ball screening device to solve the problems mentioned in the background art, such as the inconvenience of batch cutting and the low cutting efficiency of existing cutting methods.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a phosphor bronze ball screening device, including a screening cylinder, multiple discharge plates disposed at the bottom of the screening cylinder, and support legs disposed at the bottom of the discharge plates, and also including a material handling mechanism disposed inside the screening cylinder and a feeding mechanism disposed on the side wall of the screening cylinder; the bottom of the screening cylinder is provided with multiple sets of screening holes, the diameter of the multiple sets of screening holes increases sequentially along the circumference of the screening cylinder, and the multiple discharge plates are all U-shaped and are respectively disposed at the bottom of the multiple sets of screening holes.

[0005] Furthermore, the material handling mechanism includes a motor and a material handling plate; the motor is located in the middle of the lower part of the screening cylinder and the motor output shaft passes through the bottom of the screening cylinder and is connected to the material handling plate.

[0006] Furthermore, the feeding mechanism includes a feeding plate disposed on the side wall of the screening cylinder, a gantry frame disposed on the feeding plate, and an electric push rod disposed on the gantry frame; a baffle is slidably connected to the feeding plate, and the output shaft of the electric push rod passes through the gantry frame and is connected to the baffle.

[0007] Furthermore, the material swaying plate consists of a rotating drum connected to the motor output shaft and two swing plates disposed on the rotating drum, and the included angle formed between the two swing plates is adapted to a set of screening holes.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. Automatic Feeding Control: This invention achieves automated feeding control by incorporating an ultrasonic sensor, an electric actuator, and a baffle. When the ultrasonic sensor detects that the number of phosphor bronze balls in the screening cylinder is less than a certain threshold, the PLC controller controls the output shaft of the electric actuator to retract, causing the baffle to move upward, allowing the phosphor bronze balls to enter the screening cylinder. When the number of phosphor bronze balls exceeds the threshold, the output shaft of the electric actuator extends, and the baffle moves downward to block the feed plate, preventing excessive phosphor bronze balls from entering. This ensures the stability and efficiency of the screening process, reduces manual operation costs, and improves screening efficiency and quality.

[0010] 2. Uniform Screening: The motor and swivel plate design of the feeding mechanism effectively drive the phosphor bronze balls to rotate within the screening cylinder during the screening process. The motor drives the swivel plate to rotate, ensuring that the phosphor bronze balls are fully dispersed and evenly contact the screening holes, avoiding missed or mis-screening, guaranteeing that the phosphor bronze balls after screening are of consistent size, and improving screening accuracy.

[0011] 3. High-efficiency sorting and screening: The diameter of multiple sets of screening holes at the bottom of the screening cylinder increases sequentially along the circumference, and the discharge plate is U-shaped and corresponding to each screening hole. This design enables convenient and efficient sorting and screening of phosphor bronze balls of different sizes. The screened phosphor bronze balls fall directly into different collection devices through the discharge plate, facilitating subsequent processing and greatly improving screening efficiency to meet the needs of large-scale, batch production.

[0017] Please see Figures 1 to 2A phosphor bronze ball screening device comprises a screening cylinder 1, a discharge plate 2, support legs 3, a material-lifting mechanism, and a feeding mechanism. The screening cylinder 1 is cylindrical with a screen plate at the bottom. Multiple sets of screening holes 4 are formed on the screen plate, with the hole diameter increasing sequentially along the circumference of the screening cylinder 1 and distributed clockwise to screen the phosphor bronze balls. Multiple discharge plates 2 are U-shaped and arranged at the bottom of the screen plate, corresponding one-to-one with the sets of screening holes 4. One end of the discharge plate 2 is inclined downwards to facilitate the discharge of the screened phosphor bronze balls. Multiple support legs 3 are also provided and connected to the bottom of the discharge plates 2. The material-lifting mechanism is located inside the screening cylinder 1 and is used to move the phosphor bronze balls for screening. The feeding mechanism is located on the side wall of the screening cylinder 1 for feeding the balls.

[0018] Specifically,

[0019] The material handling mechanism consists of a motor 5 and a material handling plate 6. The motor 5 is located at the bottom and middle of the screening cylinder 1. The output shaft of the motor 5 passes through the bottom of the screening cylinder 1, is located inside the screening cylinder 1, and is connected to the material handling plate 6. The material handling plate 6 consists of a rotating cylinder connected to the output shaft of the motor 5 and two swing plates mounted on the rotating cylinder. The included angle formed between the two swing plates is fan-shaped and its size is adapted to the size of each set of screening holes 4. When the motor 5 is started, it can drive the material handling plate 6 to rotate. The motor 5 is specifically a stepper motor and is equipped with an encoder.

[0020] The feeding mechanism consists of a feeding plate 7, a gantry frame 8, an electric actuator 9, and a baffle 10. A feeding inlet is provided on the side wall of the screening cylinder 1. The feeding plate 7, also U-shaped, is located at the feeding inlet on the side wall of the screening cylinder 1, above the set of screening holes 4 with the smallest aperture. The gantry frame 8 is mounted on the feeding plate 7, and the electric actuator 9 is installed on the gantry frame 8. The output shaft of the electric actuator 9 passes through the gantry frame 8 and connects to the baffle 10, which in turn slides vertically with the feeding plate 7. The electric actuator 9 drives a self-locking function and a position feedback function.

[0021] An ultrasonic sensor is also installed on the screening cylinder 1. The ultrasonic sensor is mounted above the screening cylinder 1 via an L-shaped plate, close to the smallest set of screening holes 4, and its signal output terminal is perpendicular to the screening cylinder 1 (not shown in the figure). The ultrasonic sensor, motor 5, and electric actuator 9 are all interlocked with the PLC controller. When the ultrasonic sensor detects that the number of phosphor bronze balls in the screening cylinder 1 is less than a certain threshold, it transmits a signal to the PLC controller. The PLC controller controls the output shaft of the electric actuator 9 to retract, thereby driving the baffle 10 to move upward, so that the phosphor bronze balls can pass through the feed plate 7 and enter the screening cylinder 1. When the ultrasonic sensor detects that the number of phosphor bronze balls in the screening cylinder 1 is greater than a certain threshold, it transmits a signal to the PLC controller. The PLC controller controls the output shaft of the electric actuator 9 to extend, thereby driving the baffle 10 to move downward and block the feed plate 7. When the output shaft of the electric actuator 9 is in the retracted state, the motor 5 drives the swing plate 6 to be at the two edges of the smallest set of screening holes 4. When the output shaft of the electric actuator 9 is in the extended state, the motor 5 drives the swing plate 6 to rotate.

[0022] Working principle of this utility model:

[0023] The feed plate 7 of this device is located below the discharge port of the screw conveyor. In the initial state, the output shaft of the electric push rod 9 is in the retracted state, the baffle 10 moves upward, and the motor 5 drives the two swing plates of the swing plate 6 to rotate to the two edges of the smallest set of screening holes 4 (e.g., Figure 1 As shown), the rotation direction of the output shaft of motor 5 is the same as the direction in which the diameters of the multiple sets of screening holes 4 increase sequentially.

[0024] The cleaned phosphor bronze balls are conveyed to the feed plate 7 by a screw conveyor, and then enter the chamber formed by the screening cylinder 1 and the two swing plates. When the number of phosphor bronze balls in the screening cylinder 1 exceeds the set threshold, the ultrasonic sensor sends a signal to the PLC controller. The PLC controller controls the output shaft of the electric push rod 9 to extend, thereby driving the baffle 10 to move downward, so that the phosphor bronze balls are blocked on one side of the feed plate 7 and do not enter the screening cylinder 1. When the output shaft of the electric push rod 9 extends, it transmits a signal to the PLC controller, which controls the motor 5 to start, thereby driving the swing plate 6 to rotate one revolution, so as to agitate the phosphor bronze balls to rotate in the screening cylinder 1 and fall into different screening holes 4, thus completing the screening of the phosphor bronze balls. The screened phosphor bronze balls fall into different collection devices through the discharge plate 2 for further processing.

[0025] After the material plate 6 rotates one revolution and resets, it transmits a signal to the PLC controller. The PLC controller controls the output shaft of the electric push rod 9 to retract, which in turn drives the baffle 10 to move upward, so that the phosphor bronze balls re-enter the screening cylinder 1. This cycle is repeated to complete the screening operation of the phosphor bronze balls.
