[0002] Steel balls, as an important basic component, can be classified into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, alloy balls, etc., according to the processing materials. They are widely used in hardware, electronics, wrought iron, machinery and equipment, power, mining, metallurgy and other fields. As an important part of industrial production, the quality and cost of steel balls directly affect the overall performance and market competitiveness of products. In the process of steel ball manufacturing, it is unavoidable that steel balls with unqualified dimensions will appear. Separating qualified steel balls from the produced steel balls is an essential step.

[0003] Existing steel ball sorting devices, such as the automatic steel ball sorting device with publication number CN221086399U, include a frame and a storage bin. The lowest end of the storage bin has a guide port with a guide plate. Baffles are provided on both sides of the guide plate in the width direction. A valve plate is detachably provided on the end of the baffle plate near the guide port. Sorting components are provided on the guide plate.

[0004] While the aforementioned patent achieves the sorting of steel balls and is relatively simple to operate, it requires multiple sorting operations for steel balls of different sizes when dealing with mixtures containing steel balls of various diameters. This increases the complexity of the sorting process and reduces the overall sorting efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of existing devices in that they are difficult to sort steel balls of a specified size, this utility model provides a steel ball finished product sorting device.

[0006] The technical solution of this utility model is: a steel ball finished product sorting device, including a base, a sorting box, a transmission box, a worm, a worm wheel, a lead screw, a nut, a sorting plate, an anti-blocking device, a rocker arm, a baffle plate, a push rod, a discharge plate, and a limiting mechanism.

Two transmission boxes are located on the upper side of the sorting box, each with a rotatable worm on its inner wall and a worm wheel rotatably mounted on its lower inner side. The worm and worm wheel mesh, and a lead screw is connected to the upper side of the worm wheel. The screw is rotatably connected to the upper side of the inner wall of the transmission box. A nut is fitted on the screw, and the nut is connected to the sorting plate. The sorting plate is slidably connected to the sorting box. An anti-clogging device is provided on the lower side of the sorting plate. A rocker arm is connected to the front side of the worm gear. Two baffle plates are slidably provided inside the upper side of the base. Two discharge ports are opened on the lower side of the sorting box. The two discharge ports are located on the left side of the two sorting plates respectively. A push rod is provided on the front side of the baffle plate. A sliding groove is opened on the front side of the base. The push rod is slidably connected to the sliding groove. Two discharge plates are provided on the base. A limit mechanism is provided on the left side of each sliding groove on the base.

[0007] Furthermore, it also includes sliding plates. Sliding plates are provided on the upper side of both sorting plates, and sliding grooves are opened on the front side of both transmission boxes. The sliding plates are slidably connected to the sliding grooves, and scales are provided next to the sliding grooves.

[0008] Furthermore, the anti-clogging device includes a cylinder and a pusher frame. A cylinder is provided on the lower left side of both sorting plates. The output shaft of the cylinder is connected to the pusher frame, and the pusher frame is slidably connected to the sorting plate.

Detailed Implementation

[0022] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] A steel ball sorting device, such as Figures 1-5As shown, the system includes a base 1, a sorting box 2, a transmission box 3, a worm gear 4, a worm wheel 5, a lead screw 6, a nut 7, a sorting plate 8, an anti-clogging device, a rocker arm 9, a baffle plate 12, a push rod 13, a discharge plate 14, and a limiting mechanism. The upper side of the base 1 is inclined with the left side higher than the right side. The sorting box 2 is located on the upper side of the base 1. The left and right sides of the sorting box 2 are respectively provided with a feed inlet and a discharge outlet. Two transmission boxes 3 are located on the upper side of the sorting box 2. The inner walls of both transmission boxes 3 are rotatably equipped with worm gears 4. The lower inner side of both transmission boxes 3 is rotatably equipped with worm wheels 5. The worm gears 4 and worm wheels 5 mesh with each other. The upper side of the worm wheel 5 is connected to the lead screw 6. The lead screw 6 is rotatably connected to the upper inner wall of the transmission box 3. The lead screw 6 is fitted with a nut 7. The nut 7 is connected to the left side of the sorting plate 8. The sorting plate 8... The sorting plate 8 is slidably connected to the sorting box 2. An anti-clogging device is provided on the lower side of the sorting plate 8. A rocker arm 9 is connected to the front side of the worm gear 4. The rocker arm 9 is used to control the rotation of the worm gear 4. Two baffle plates 12 are slidably provided inside the upper side of the base 1. Two discharge ports are opened on the lower side of the sorting box 2. The two discharge ports are located on the left side of the two sorting plates 8 respectively. When the two baffle plates 12 slide to the left, they will block the two discharge ports respectively. A push rod 13 is provided on the front side of the baffle plate 12. A sliding groove is opened on the front side of the base 1. The push rod 13 is slidably connected to the sliding groove. Two discharge plates 14 are provided on the lower side of the upper part of the base 1. The discharge plates 14 are located below the discharge ports. A limiting mechanism is provided on the left side of each sliding groove on the base 1. The limiting mechanism is used to limit the push rod 13 so that the discharge plate 14 does not slip due to gravity.

[0024] In operation, cranking lever 9 rotates the worm gear 4, which in turn rotates the worm wheel 5 and lead screw 6. The rotation of lead screw 6 causes nut 7 to move up or down, which in turn moves sorting plate 8 up or down. The distance between the left sorting plate 8 and the bottom of sorting box 2 is adjusted to allow qualified steel balls to pass through, while the distance between the right sorting plate 8 and the bottom of sorting box 2 is adjusted to prevent qualified steel balls from passing through. Then, steel balls to be sorted are poured into the feed inlet of sorting box 2. Under gravity, the steel balls move to the right. When passing the left sorting plate 8, larger steel balls with a diameter greater than qualified steel balls are blocked by the left sorting plate 8, while qualified steel balls and those with a diameter less than qualified steel balls are blocked. The small steel balls can pass smoothly through the left sorting plate 8. When qualified steel balls and small steel balls pass through the right sorting plate 8, the qualified steel balls are blocked by the right sorting plate 8, while the small steel balls can pass smoothly through the right sorting plate 8 and be discharged from the outlet. The anti-blocking device will continuously push the steel balls that cannot pass through the sorting plate 8 during the sorting process to prevent the steel balls that cannot pass through the sorting plate 8 from accumulating on the left side of the sorting plate 8 and blocking it. After the sorting is completed, the limiting mechanism is opened, and the baffle plate 12 is moved by the push rod 13 to expose the discharge port. The large steel balls and qualified steel balls are discharged from the two discharge ports respectively. After all the steel balls are discharged, the baffle plate 12 is moved back to its original position, and the limiting mechanism is used to limit the push rod 13.

[0025] like Figure 6As shown, it also includes a sliding plate 32. The upper side of both sorting plates 8 is provided with a sliding plate 32, and the front side of both transmission boxes 3 is provided with a sliding groove 31. The sliding plate 32 is slidably connected to the sliding groove 31. A scale is provided next to the sliding groove 31. When the sorting plate 8 contacts the lower side of the inside of the sorting box 2, the sliding plate 32 is located at the bottom of the scale. When adjusting the height of the sorting plate 8, the sorting plate 8 moves up and down, and the sliding plate 32 will slide on the sliding groove 31 accordingly. The distance of movement of the sorting plate 8 and the sliding plate 32 can be adjusted according to the scale next to the sliding groove 31, so that the distance between the sorting plate 8 and the sorting box 2 is more accurate.

[0026] like Figure 4 As shown, the anti-clogging device includes a cylinder 10 and a pusher frame 11. Two cylinders 10 are provided on the lower left side of each of the two sorting plates 8. The output shafts of the two cylinders 10 are connected to the pusher frame 11, and the pusher frame 11 is slidably connected to the sorting plate 8. During sorting, the cylinder 10 drives the pusher frame 11 to move back and forth. The pusher frame 11 pushes the steel balls that cannot pass through the sorting plate 8, so that they are not blocked.

[0027] like Figure 7 As shown, the limiting mechanism includes a support ring 15, a bolt plate 16, and a bolt rod 17. The base 1 has three support rings 15, all of which are slidably connected to the bolt rod 17. The base 1 has a bolt plate 16 that cooperates with the bolt rod 17. When the push rod 13 moves to the leftmost end, the bolt rod 17 is exactly located to the upper right of the push rod 13. When it is necessary to drop material, the bolt rod 17 is lifted upwards, and the bolt plate 16 is used to fix the position of the bolt rod 17. Then, the material dropping plate 14 can be moved by the push rod 13 to drop material. When it is necessary to lock the push rod 13, the bolt plate 16 is removed from the bolt rod 17 and released. The bolt rod 17 will then fall by its own weight and firmly lock the push rod 13, thus realizing the limiting function.

[0028] The front and rear sides of the sorting box 2 are made of transparent material. Through the transparent material, the operator can directly observe the situation inside the sorting box 2 during the sorting process and judge the completion status of the sorting work.

[0029] The distance between the discharge port and the sorting plate 8 is less than the radius of the steel ball; the distance between the discharge port and the sorting plate 8 allows the steel ball to fall more smoothly during discharge, so that it does not stay in the sorting box 2.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
