Description

Technical Field

[0001] This utility model belongs to the field of steel ball screening technology, specifically relating to a steel ball production screening device. Background Technology

[0002] As an important basic component in industry, steel balls have diverse production processes and material choices, covering various types such as ground steel balls, forged steel balls, and cast steel balls, as well as different material classifications such as bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, and alloy balls.

[0003] During the steel ball production process, steel balls of different diameters may appear, requiring them to be packaged separately. For example, a steel ball screening device for a steel ball conveyor, patent number CN2023236250589, includes a fixed support, a motor, an eccentric wheel, and multiple sets of screening screens. The motor drives the drive pulley to rotate, which in turn drives the first connecting shaft to rotate, and finally drives the three screening screens to move left and right. The steel balls are screened by the three screening screens with different screen hole sizes. Although this screening method can complete the screening of steel balls, the steel balls will quickly flow to the discharge port after falling onto the screening screen, resulting in incomplete screening.

[0022] like Figures 1 to 6 As shown, this utility model provides a technical solution: a steel ball production screening device, including a base assembly 1, the base assembly 1 including a base plate 11, at least two sets of universal wheels 12 are installed at one lower end of the base plate 11, at least two sets of directional wheels 13 are installed at the other lower end of the base plate 11, a high mounting frame 14 is installed at one upper end of the base plate 11, the high mounting frame 14 is opposite to the universal wheels 12, a low mounting frame 15 is installed at the other upper end of the base plate 11, the low mounting frame 15 is connected to the directional wheels 13, and telescopic members 16 are respectively installed on the top surfaces of the high mounting frame 14 and the low mounting frame 15. The top surface of the telescopic member 16 is connected to the bottom surface of the screening shell 2. The telescopic member 16 can be a spring, but is not limited to a spring, through the mutual cooperation of the directional wheels 13 and the universal wheels 12. The screening device can be adjusted in position to suit different production scenarios. A screening shell 2 is installed at an incline on the top surface of the base assembly 1. A vibration motor 3 is installed at the bottom of the screening shell 2. The vibration motor 3 drives the screening shell 2 to vibrate on the top surface of the base assembly 1. A screening component 4 is installed inside the screening shell 2. The vibration motor 3 drives the screening shell 2 to shake, thereby screening the steel balls inside the screening shell 2. A baffle assembly 5 is installed at the lower end of the screening shell 2. The baffle assembly 5 is operably inserted into the screening component 4, dividing the screening component 4 into several receiving spaces. That is, steel balls of different diameters can be screened in different receiving spaces. By using the baffle assembly 5 to separate the steel balls, the steel balls can be fully screened without replacing the screening plate 41, thus completing the screening of steel balls of various sizes and improving the screening efficiency.

[0023] In a further embodiment, the screening shell 2 includes a shell body 21, which is mounted on the top surface of the base assembly 1. Mounting plates 22 are mounted on both ends of the shell body 21 along its length. The mounting plates 22 are mounted longitudinally on the bottom surface of the shell body 21. A portion of the partition assembly is mounted between the mounting plates 22. The screening assembly 4 includes a screening plate 41, which is horizontally mounted inside the screening shell 2. The screening plate 41 has several rectangular holes 42 along its longitudinal direction, parallel to the width direction of the screening plate 41. A portion of the partition assembly 5 is operably inserted into the rectangular holes 42, dividing the screening plate 41 into several screening sections. Each screening section of the screening plate 41 has several screening holes 43. In this embodiment, three sets of screening holes 43 are provided. The rectangular array of screening holes 43 penetrates the screening plate 41, and the diameter of the screening holes 43 increases sequentially from the inclined high end to the low end. The system is large and capable of screening steel balls of different diameters. Each screening section has a funnel-shaped receiving shell 44 installed below it. The outlet of the receiving shell 44 is connected to an external storage box via a pipe. The partition assembly 5 includes a drive motor mounted on the side of the mounting plate 22. A rotating shaft 51 is mounted on the output end of the drive motor and rotatably mounted on the mounting plate 22. A linear array of incomplete gears 52, the same number as the rectangular holes 42, is mounted on the rotating shaft 51. The incomplete gears 52 are located below the rectangular holes 42. A key ring 53 is sleeved around the outside of each incomplete gear 52. Straight racks 54 are provided on opposite sides of the inner wall of the key ring 53. The incomplete gears 52 intermittently mesh with the straight racks 54. A partition plate 55 is mounted on the top of the key ring 53, located below the rectangular holes 42. The partition plate 55, in cooperation with the key ring 53 and the incomplete gears 52, inserts into or moves away from the rectangular holes 42.

[0024] Through the above technical solution, the present invention can achieve the following working process:

[0025] When screening steel balls, firstly, the baffles 55 at both ends are inserted into the screening holes 43, and the baffle 55 in the middle is disengaged from the screening holes 43. Then, the steel balls to be screened are placed into the top receiving cavity. The vibrating motor 3 starts, causing the screening assembly 4 to shake and screen the steel balls, separating out the smaller diameter balls. After the steel balls are fully screened, the drive motor, in conjunction with the incomplete gear 52 and the rack 54, moves the baffles 55, that is, the baffles 55 at both ends are moved out of the rectangular holes 42, and the baffles 55 in the middle are removed. When the baffle plate 55 is inserted into the rectangular hole 42, the steel ball at the top rolls onto the middle baffle plate 55 for further screening, separating out the larger diameter steel balls. After the second screening is completed, the middle baffle plate 55 is moved out of the rectangular hole 42. At this time, the baffle plates 55 at both ends are inserted into the rectangular hole 42. The remaining steel balls after screening flow to the end baffle plate 55 for further screening. At the same time, new steel balls to be screened are injected into the upper receiving space. By repeatedly adjusting the baffle plate 55, all the steel balls to be screened can be screened.

[0026] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
