[0013] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the preferred implementation embodiments of the present utility model will be described below in conjunction with specific embodiments. However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0014] The present utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0015] Embodiment 1

[0016] Refer to Figure 1 and Figure 2 As shown, a steel ball sorting machine involved in this embodiment includes a base 1. A left frame 2 and a right frame 3 are provided on the base 1. Two parallel compound rollers 4 are rotatably connected between the left frame 2 and the right frame 3. A rolling track (not marked) for steel balls to roll is formed between the two compound rollers 4. The compound roller 4 includes a sorting roller 41 and a feeding roller 42 arranged coaxially. The diameter of the feeding roller 42 is smaller than that of the sorting roller 41. A first feeding ramp 5 arranged in a front-high and rear-low inclined manner is provided below the sorting roller 41. A second feeding ramp 6 arranged in a front-low and rear-high inclined manner is provided below the feeding roller 42.

[0017] Furthermore, a feeding pipe 10 is provided above the feeding end 401.

[0018] In this implementation, a number of steel balls to be screened (only the undersize steel balls are screened out) are poured one by one at one end of the rolling track formed between two adjacent compound rollers 4. The steel balls gradually roll from the end far from the feeding roller 42 to the end close to the feeding roller 42. During this period, if the diameter of the steel ball is undersize, it will fall from the rolling track of the sorting roller 41 section, and the first feeding ramp 5 will complete the feeding; if the diameter of the steel ball is not undersize, it will continue to roll to the position of the feeding roller 42 and fall from the rolling track of the feeding roller 42 section, and the second feeding ramp 6 will complete the feeding, thereby realizing the sorting operation.

[0019] Among them, through the setting of the feeding pipe 10, it is used for feeding the steel balls.

[0020] Example 2

[0021] See also Figure 1 and Figure 2 As shown, a steel ball sorting machine involved in this embodiment is further configured on the basis of Example 1, and also includes a power assembly for controlling the rotation of the composite roller 4; the power assembly includes a gear 7 arranged at one end of the composite roller 4, any of the gears 7 is meshed with another gear 7, and one of the gears 7 is transmission-connected to a motor 8 for controlling the rotation; a reducer 9 is connected in series between the motor 8 and the gear 7.

[0022] In this embodiment, the power assembly is arranged so that the steel balls rolling on the composite roller 4 (ie, the raceway) roll more frequently, thereby making the screening more accurate.

[0023] Example 3

[0024] See also Figure 1 and Figure 2 As shown, a steel ball sorting machine involved in this embodiment is further configured on the basis of embodiments 1 and 2, wherein the composite roller 4 is arranged at an angle, and the composite roller 4 has a loading end 401 away from the unloading roller and a unloading end 402 close to the unloading roller, and the unloading end 402 is lower than the loading end 401.

[0025] In this embodiment, the composite roller 4 is arranged tilted so that the raceway is also tilted accordingly, so that the steel balls dropped thereon can roll down naturally due to gravity, and the external force requirement is low or no requirement.

[0026] The steel ball sorting machine involved in the utility model uses an inclined roller conveyor to convey the screened steel balls. When the diameter of the fine grinding steel balls is too small, they will be screened out without excessive mutual collision. The operation is relatively quiet, environmentally friendly and reliable, with complete overall functions and strong practicality.
