Abstract
Description
Technical Field
[0001] This utility model relates to steel ball sorting, specifically a steel ball size sorting machine. Background Technology
[0002] Steel ball sorting machines can separate steel balls of different diameters and transport them to designated locations. Because steel balls come in a wide variety of diameters, these sorting machines typically require numerous outlet channels, each corresponding to a specific diameter. The large number of outlet channels makes the machine complex and space-consuming. However, since a single sorting operation doesn't involve all these diameters of steel balls, many outlet channels remain unused. Utility Model Content
[0003] To address the shortcomings of the prior art, this invention provides a steel ball size sorting machine. This invention can change the size and position of the ball receiving space so that the limited outlet channel can accommodate steel balls of different diameters, resulting in high utilization of the outlet channel and small space occupation.
[0004] To achieve the above technical objectives, this utility model adopts the following technical solution: a steel ball size sorting machine, including an outer cover, a sorting rod assembly fixed inside the outer cover, the sorting rod assembly being provided with a sorting groove, the inner diameter of the sorting groove changing from small to large, and the sorting rod assembly being inclined downwards; a ball receiving plate being provided below the sorting rod assembly, the ball receiving plate being provided with two partitions, the two partitions dividing the ball receiving plate into three ball receiving spaces, the two partitions being movable along the ball receiving plate to change the size of the three ball receiving spaces, the outer cover also being fixed with an inclined plate, the inclined plate being provided with two outer channels, the two outer channels respectively corresponding to the two outer ball receiving spaces, and the intermediate channel formed between the two outer channels corresponding to the intermediate ball receiving space.
[0005] The sorting rod assembly includes multiple intermediate rods and two side rods, with the sorting groove formed between the multiple intermediate rods and the two side rods.
[0006] Both sides of the intermediate rod are provided with arc-shaped surfaces, and one side of the intermediate rod is provided with an arc-shaped surface.
[0007] The ball receiving plate has two gaps through which fastening rods pass. One end of the fastening rod is threaded to the partition, and the other end is fixed with a handle, so that the partition can be moved to change the size of the three ball receiving spaces.
[0008] The outer channel includes a movable inner plate, a fixed outer plate, and a telescopic structure. Both the movable inner plate and the fixed outer plate are in an upright state. One side of the telescopic structure is fixedly connected to the movable inner plate, and the other side is fixedly connected to the fixed outer plate. The bottom surface of the telescopic structure is placed on the inclined plate. When the movable inner plate moves, it can change the width of the outer channel. The movable inner plate is fixedly connected to the partition.
[0009] The telescopic structure includes a fixed plate, a middle telescopic plate, and a movable telescopic plate. One side of the fixed plate is fixedly connected to the fixed outer plate, and the other side has a first hole. The bottom surface of the fixed plate is fixedly connected to the inclined plate. One side of the middle telescopic plate extends into the first hole, and the other side has a second hole. One side of the movable telescopic plate extends into the second hole, and the other side is fixedly connected to the movable inner plate.
[0010] The intermediate channel is formed between the two movable inner plates.
[0011] The outer cover includes a front side plate, the bottom surface of which is higher than the partition plate and lower than the bottom surface of the sorting rod assembly.
[0012] In summary, this utility model achieves the following technical effects:
[0013] This invention uses gradually increasing sorting troughs to sort steel balls. Steel balls of different sizes fall onto a receiving plate on the lower side and are then conveyed out through corresponding channels. This invention has three channels and three receiving spaces, and can be moved at any time to accommodate steel balls of different diameters.

[0024] Example:
[0025] Figure 1 A steel ball size sorting machine includes an outer cover 1, inside which a sorting rod assembly 2 is fixed. The sorting rod assembly 2 is provided with a sorting groove 23, the inner diameter of which varies from small to large, and the sorting rod assembly 2 is inclined downward. Below the sorting rod assembly 2, a ball receiving plate 3 is provided. The ball receiving plate 3 is provided with two partitions 4, which divide the ball receiving plate 3 into three ball receiving spaces. The two partitions 4 can move along the ball receiving plate 3 to change the size of the three ball receiving spaces. The outer cover 1 is also fixed with an inclined plate 5, on which two outer channels 6 are provided. The two outer channels 6 correspond to the two outer ball receiving spaces respectively, and the intermediate channel formed between the two outer channels 6 corresponds to the intermediate ball receiving space.
[0026] This invention uses gradually increasing sorting troughs to sort steel balls. Steel balls of different sizes fall onto a receiving plate on the lower side and are then conveyed out through corresponding channels. This invention has three channels and three receiving spaces, and can be moved at any time to accommodate steel balls of different diameters. It sorts steel balls of different diameters with fewer channels and is suitable for sorting two or three types of steel balls in a factory.
[0027] Figure 2 This is a top view of the sorting rod assembly. The sorting rod assembly 2 includes multiple intermediate rods 21 and two side rods 22. The sorting groove 23 is formed between the multiple intermediate rods 21 and the two side rods 22. Both ends of the multiple intermediate rods 21 and the two side rods 22 are welded to the inner wall of the outer cover.
[0028] Figure 3 This is a schematic diagram of the intermediate rod 21. Both sides of the intermediate rod 21 are provided with arc-shaped surfaces 201, and one side of the intermediate rod 21 is provided with an arc-shaped surface 201.
[0029] The curved surface 201 of this invention provides a better raceway, allowing the steel ball to roll more smoothly. The curved surface will not scratch the surface of the steel ball.
[0030] Figure 4 This is a bottom view of the connection between the ball receiving plate and the partition. The ball receiving plate 3 has two gaps 301. A fastening rod 302 passes through the gaps 301. One end of the fastening rod 302 is threaded to the partition 4, and the other end is fixed with a handle 303, so that the partition 4 can move to change the size of the three ball receiving spaces.
[0031] The ball receiving plate 3 is welded and fixed to the inner wall of the outer cover.
[0032] Loosen the fastening rod to allow partition 4 to move freely to accommodate different steel ball sizes. For example, if the steel balls are 2cm, 4cm, and 6cm in diameter, move the two partitions to 3cm and 5cm positions to create three ball-receiving spaces. For the next sorting of steel balls with diameters of 1cm, 3cm, and 5cm, move the partitions to 2cm and 4cm positions to accommodate different diameters. Similarly, to sort steel balls with diameters of 1cm, 6cm, and 16cm, move the partitions approximately 3cm and 10cm respectively.
[0033] To accommodate the movement of the partition, this application designs the channel as a telescopic structure:
[0034] like Figure 1 As shown, the outer channel 6 includes a movable inner plate 304, a fixed outer plate 605, and a telescopic structure. Both the movable inner plate 304 and the fixed outer plate 605 are in an upright state. One side of the telescopic structure is fixedly connected to the movable inner plate 304, and the other side is fixedly connected to the fixed outer plate 605. The bottom surface of the telescopic structure is placed on the inclined plate 5. When the movable inner plate 304 moves, it can change the width of the outer channel 6. The movable inner plate 304 is fixedly connected to the partition plate 4.
[0035] When any partition is moved, the worker pulls the corresponding movable inner panel 304 along with it. The telescopic structure can extend and retract to change the width of the outer passage. At the same time, after the movable inner panel moves, the width of the middle passage formed between the two movable inner panels 304 also changes accordingly, so that the passage and the partition move together, and the passage and the partition cooperate better.
[0036] The telescopic structure includes a fixed plate 601, an intermediate telescopic plate 602, and a movable telescopic plate 603. One side of the fixed plate 601 is fixedly connected to the fixed outer plate 605, and the other side has a first hole. The bottom surface is fixedly connected to the inclined plate 5. One side of the intermediate telescopic plate 602 extends into the first hole, and the other side has a second hole. One side of the movable telescopic plate 603 extends into the second hole, and the other side is fixedly connected to the movable inner plate 304.
[0037] The three plates of this utility model, namely the fixed plate 601, the intermediate telescopic plate 602, and the movable telescopic plate 603, adopt a telescopic structure, which is the prior art. For example, a stop bar is provided on the side of the intermediate telescopic plate 602, and a movable groove is provided in the first hole. The stop bar moves in the movable groove, and the space for movement of the stop bar is restricted by the movable groove to prevent the fixed plate 601 and the intermediate telescopic plate 602 from separating. The intermediate telescopic plate 602 and the movable telescopic plate 603 operate on the same principle.
[0038] The intermediate channel is formed between the two movable inner plates 304.
[0039] The outer cover 1 includes a front side panel 11, the bottom surface of which is higher than the partition 4 and lower than the bottom surface of the sorting rod assembly 2. The rear side panel 12 can be opened to loosen the handle 303.
[0040] The sorting rod assembly can also be marked with scales to correspond to the different sizes of steel balls.
[0041] The inclined plate 5 is welded to the side of the ball receiving plate 3 at its highest point.
[0042] Working principle:
[0043] In this invention, steel balls are poured into the outer cover 1 and move along the sorting groove 23. The sorting rod group 2 is inclined, so the steel balls roll smoothly under their own weight and fall into the corresponding receiving space at the corresponding size position. The receiving plate 3 is inclined to facilitate the steel balls rolling into the corresponding channel. When the size of the steel balls changes significantly, the partition and the movable inner plate of the channel are moved together to change the width of the receiving space and the channel, corresponding to the different positions where the steel balls fall.
[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
