Description

Technical Field

[0001] The utility model relates to the technical field of steel ball screening, and more specifically, to a screening and collecting device for steel balls of different specifications. Background Technique

[0002] Steel balls are metal products, usually made of materials such as carbon steel and stainless steel, and are spherical in shape. Steel balls are widely used in industrial production, such as as bearing parts, grinding media, sandblasting materials, etc. They have the advantages of high hardness, strong wear resistance, corrosion resistance, etc., so they are in demand in many fields.

[0003] A steel ball screening and collecting device is a special device for screening and collecting steel balls of different specifications. This device usually consists of components such as a machine body, a screen mesh, and a driving device. By vibrating or rotating, etc., the steel balls are screened on the screen mesh, and the steel balls that meet the specification requirements are collected to achieve the purpose of classifying and extracting the steel balls.

[0004] In the process of screening and collecting steel balls of different specifications by the existing steel ball screening and collecting device, some steel balls may have irregular shapes due to wear during the production process or use process, which may cause the steel balls to get stuck on the screen mesh and form blockages. And the blockage of the screen holes often requires manual cleaning by personnel, which will undoubtedly consume a lot of manpower and bring great troubles to the actual use.

[0005] Secondly, when screening steel balls, often a large number of steel balls are directly put into the screening device by personnel. However, when placed in this way, the steel balls often overlap, and due to their easy rolling nature, the steel balls will quickly pass over other steel balls and it is difficult to obtain effective screening, which will undoubtedly affect the screening effect and cause many inconveniences in use.

[0006] In view of this, we propose a screening and collecting device for steel balls of different specifications. Content of the Utility Model

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present utility model are as follows: During the screening process of steel balls, if the steel balls are blocked in the screen holes inside the first screen plate or the second screen plate, the first screw motor and the second screw motor can be started to drive their respective screen cleaning components one and two to move reciprocally. During the movement of multiple sliding blocks, the gears inside the sliding blocks will drive the rotating rollers carrying the transmission gears to rotate. During the rotation, the connecting sleeves on the outer walls of the rotating rollers will also rotate. Once the connecting sleeve reaches the through-hole, the multiple return springs at the bottom of the connecting sleeve will rebound, and then drive the knocking blocks to perform mobile cleaning on the first screen plate or the second screen plate. When the knocking blocks pass through the through-hole, they will retract into the connecting sleeve again by using the arc surface on the right side of the knocking blocks and the return springs, for re-accumulation of force, making it more effective to clean the steel balls blocked in the screen holes, reducing the labor burden brought by manual cleaning by personnel, and improving the cleaning efficiency;

[0019] Secondly, when discharging the steel balls, the rotating motor can be used to drive the spiral feeding rod to rotate, so that an appropriate amount of steel balls can be gradually put in, avoiding putting in a large number of steel balls at one time, which may cause overlapping and rapid passing through the screen. And due to the existence of the height limiting plate, when the steel balls are being screened, the overlapping situation can be further reduced, effectively improving the screening efficiency and screening effect of the steel balls, and reducing the labor intensity caused by the need to screen the steel balls back and forth.

A connecting column 110 and a vibration motor 140 are arranged at the bottom of the fixed box 100, which facilitates using the vibration motor 140 to vibrate the fixed box 100, and then better vibrate and screen the steel balls.

[0031] A fixing base 120 is sleeved inside multiple connecting columns 110, a spring 130 is sleeved on the outer walls of the multiple connecting columns 110, a feeding component is arranged on the top of the fixing box 100, the feeding component includes a feeding barrel 200, a support plate 300 is arranged at the bottom of the inner cavity of the fixing box 100, an inclined plate one 310 and a sieve plate one 320 are arranged on the outer wall on the right side of the support plate 300, and an inclined plate two 330 and a sieve plate two 340 are arranged on the outer wall on the left side of the support plate 300;

[0032] In some embodiments: the sieve plate two 340 is the area for the first screening, and the sieve plate one 320 is the secondary screening area.

[0033] A screw rod motor two 360 is arranged on the outer wall on the left side of the fixing box 100, a screw rod motor one 350 is also arranged on the outer wall on the left side of the support plate 300, the output end of the screw rod motor one 350 is connected with a screw rod one, a sieve mesh cleaning component one is sleeved on the outer circumference of the screw rod one, the sieve mesh cleaning component one includes a sliding block 351, the output end of the screw rod motor two 360 is connected with a screw rod two, and a sieve mesh cleaning component two with the same structure as the sieve mesh cleaning component one is sleeved on the outer circumference of the screw rod two to perform a more comprehensive cleaning work.

[0034] Specifically, a support frame 210 is arranged on the side wall of the feeding barrel 200, a rotating motor 220 is arranged on the top of the support frame 210, and the output end of the rotating motor 220 is connected with a spiral feeding rod 230, which is convenient for gradually putting an appropriate amount of steel balls to avoid problems such as overlapping caused by putting a large number of steel balls at one time or the steel balls passing quickly and being difficult to screen.

[0035] Further, guide blocks 352 are arranged on the front and rear outer walls of the sliding block 351, a gear 353 and a transmission gear 354 are rotatably connected inside the sliding block 351, and the gear 353 meshes with the transmission gear 354.
