Description

Technical Field

[0001] This utility model relates to the technical field of bearing ball production equipment, specifically to a multi-stage air-separation adaptive sorting device for bearing balls. Background Technology

[0002] In the field of bearing ball manufacturing, ball size sorting is a key step in ensuring product quality. Traditional sorting equipment mainly adopts two types of methods: sieve plate sorting and drum sorting. Sieve plate sorting involves the balls rolling in batches through a sieve plate with a fixed aperture, relying on size differences for sorting. Drum sorting, on the other hand, involves the balls passing through sieve holes inside a rotating drum for grading.

[0003] Existing technologies, such as the patent with publication number CN221620080U, disclose a bearing ball sorting device. This device suffers from drawbacks such as low sorting efficiency, poor stability, and repetitive operations. For example, it requires two independent operations (first taking the upper size limit, then the lower size limit) to separate qualified products. The moving balls are easily affected by mutual collisions and have difficulty falling stably at the sieve holes, leading to missed or incorrect sieving. Sieve-plate type devices require multiple repeated sieving processes, while drum type devices require extended rotation time to meet sorting requirements. To solve these problems, there is an urgent need to develop a new sorting system that can achieve multi-specification output in a single sorting operation and has strong anti-interference capabilities. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bearing ball multi-stage air separation adaptive sorting device, which can improve the sorting efficiency and stability of the balls.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage air-separated adaptive sorting device for bearing balls, comprising a main pipe, a collection hopper, a secondary pipe, and a size adjustment component; the collection hopper is connected above the beginning of the main pipe; the beginning of the secondary pipe is connected to the middle of the main pipe; the size adjustment component is located at the connection between the main pipe and the secondary pipe, and is used to adjust the size threshold of the balls flowing into the secondary pipe; the end of the main pipe is provided with a branch pipe of the same diameter as the main pipe body; the end of the secondary pipe is provided with a side through hole; both the branch pipe and the side through hole are equipped with fans.

[0006] Preferably, the inner wall of the main pipe has a groove that corresponds to and communicates with the beginning of the secondary pipe; the size adjustment assembly includes an adjustment plate and an adjustment bolt, the adjustment plate being slidably disposed in the groove; the adjustment bolt is screwed into the side wall of the main pipe and the end of the adjustment bolt abuts against the adjustment plate; the length direction of the adjustment bolt is consistent with the width direction of the main pipe.

[0026] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0027] See Figure 1-5 In one embodiment of this utility model, a bearing ball multi-stage air separation adaptive sorting device is provided. The sorting device is installed on a base 9 by necessary brackets and fasteners (bolts, etc.), and specifically includes: main pipe 1, collection hopper 2, auxiliary pipe 3, sorting fan 4, centrifugal fan 5, frame 6, active gate assembly 7, size adjustment assembly 8, and controller.

[0028] The main pipe 1 forms the main channel for conveying the balls, and its first end is connected to the collection hopper 2. The collection hopper 2 is set above the main pipe 1 by a support and is used to receive the mixed balls to be sorted. The active gate assembly 7 includes a servo motor and a gate controlled by the servo motor to open and close. The gate is set at the connection between the main pipe 1 and the collection hopper 2. The servo motor is connected to the controller by a circuit. The controller can accurately control the flow rate and start and stop of the balls entering the main pipe 1 to prevent blockage and ensure orderly sorting.

[0029] The main duct 1 is designed with a Y-shaped branch structure at its tail end, including a branch duct 11 of the same diameter and connected to the main duct body. Two centrifugal fans 5 are provided, both electrically connected in parallel to the controller. The two centrifugal fans 5 are mounted on the tail end of the main duct 1 via a frame 6, with their outlets facing the tail end of the main duct and their airflow direction towards the branch duct 11. During sorting, the balls flowing towards the tail end of the main duct 1 are affected by the airflow generated by the centrifugal fans 5. Lighter balls are blown off their original path and flow into the branch duct 11, while heavier balls resist the airflow and continue flowing out from the main outlet at the tail end of the main duct 1. This design achieves dual-path sorting of balls by weight at the end of the main duct 1.

[0030] Furthermore, an observation port 12 is longitudinally provided on the outer wall of the main pipe 1 near the collection hopper 2 to facilitate monitoring of material flow; a chute 13 is provided on the inner wall of the main pipe 1 at a position perpendicular to the observation port 12, which can be understood as the chute 13 being located below the observation port 12, and a connection port 14 is provided at the bottom of the chute 13, which is the connection port between the main pipe 1 and the beginning of the secondary pipe 3.

[0031] The secondary pipe 3 has a side through-hole 31 transversely opened on its tail side wall, and the opening path of the side through-hole 31 intersects with the main channel of the secondary pipe 3. The sorting fan 4 is installed directly opposite the side through-hole 31, and the airflow generated by the sorting fan 4 during operation is in the same direction as the opening path of the side through-hole 31. During sorting, the balls flowing into the secondary pipe 3 pass through the working area of ​​the sorting fan 4 as they flow towards its end outlet. At this time, the lighter balls are blown out by the airflow generated by the sorting fan 4 and discharged through the side through-hole 31 as light balls; the heavier balls can overcome the influence of the airflow and continue to flow out along the main channel of the secondary pipe 3 as heavy balls. This design realizes dual-path sorting of light and heavy balls of fixed size within the secondary pipe 3.

[0032] Furthermore, the sorting fan 4, like the centrifugal fan 5, is also connected to the controller via a circuit. Through the control of the controller, the sorting fan 4 and the centrifugal fan 5 can achieve start-stop and precise speed regulation.

[0033] The size adjustment assembly 8 includes an adjustment plate 81 and an adjustment bolt 84. The adjustment plate 81 is slidably disposed in the slide groove 13. The position of the adjustment plate 81 determines the effective opening of the connection port 14, thereby controlling the maximum size of the ball that can enter the secondary pipe 3.

[0034] The adjusting bolt 84 is screwed into the side wall of the main pipe 1. The end of the adjusting bolt 84 abuts against the adjusting plate 81. The length direction of the adjusting bolt 84 is consistent with the width direction of the slide groove 13 (i.e. the width direction of the main pipe). The end of the adjusting plate 81 away from the adjusting bolt 84 is inclined to improve the guiding effect.

[0035] Rotating the adjusting bolt 84 clockwise will push the adjusting plate 81 inward (towards the center of the main pipe 1) within the groove 13, gradually reducing the width / opening of the connection port 14, allowing only smaller balls to enter the secondary pipe 3. To reset the adjusting plate 81, the adjusting bolt 84 can be turned counterclockwise, and the adjusting plate 81 can be pushed back to its original position through the observation port 12 using external force.

[0036] In one embodiment, to improve the convenience of the size adjustment assembly 8, the size adjustment assembly 8 further includes a reset assembly, which includes a pin 82 and a spring 83. The pin 82 has a T-shaped structure, with one end fixedly connected to the adjusting plate 81, and the other end (T-shaped head) located outside the main pipe 1. The shaft of the pin 82 slides through the side wall of the main pipe 1. The spring 83 is sleeved on the shaft of the pin 82 and pre-compressed between the T-shaped head of the pin 82 and the outer wall of the main pipe 1. When the adjusting bolt 84 is rotated counterclockwise to reduce the thrust on it, the compressed spring 83 releases its elasticity, pushing the T-shaped head of the pin 82 (along with the adjusting plate 81) to slide outward and reset, thereby increasing the opening of the connection port 14. The pin 82, spring 83, and adjusting bolt 84 are located on the same side of the outer wall of the main pipe 1.

[0037] Furthermore, the reset assembly is provided in two sets, which are symmetrically distributed on both sides of the adjusting bolt 84 to provide a stable and balanced reset force.

[0038] The design of this sorting device, especially the dynamic adjustability of the size adjustment component 8, the combination of the Y-shaped dual-outlet centrifugal sorting at the end of the main pipe 1 and the side-hole fan sorting of the auxiliary pipe 3, enables the device to simultaneously achieve parallel sorting and output of four types of balls in the standard operating mode without intervention in the size adjustment component 8: the light ball outlet of the auxiliary pipe 3, balls smaller than the set threshold and lighter in weight (discharged through the side through-hole 31); the heavy ball outlet of the auxiliary pipe 3, balls smaller than the set threshold but heavier in weight (discharged through the main outlet of the auxiliary pipe); the light ball outlet of the main pipe 1, balls larger than the set threshold (not entering the auxiliary pipe) but lighter in weight (discharged through the branch pipe 11); and the heavy ball outlet of the main pipe 1, balls larger than the set threshold and heavier in weight (discharged through the main outlet of the main pipe 1).

[0039] In summary, this sorting device solves the problems of low efficiency and poor accuracy of traditional sorting equipment by using dual-stage control of size pre-selection and weight sorting, four parallel outputs and dynamic adjustment mechanism. It is particularly suitable for high-throughput sorting of multiple specifications of balls in bearing ball production lines, which greatly improves sorting efficiency and reduces the intensity of manual intervention, thus having significant industrial application value.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
