A sliding slot communicated with the inside of the contraction groove is opened on the side of the fixed bracket. The end of the movable rod penetrates into the sliding slot and is fixedly connected to the lifting push rod.

[0009] Preferably, a connecting rod located below the movable rod is fixed between the two fixing brackets. A motor is installed on the connecting rod, and a screw rod is fixed to the output end of the motor. The end of the screw rod threadedly penetrates through the movable rod.

[0010] Preferably, a soft magnet is fixed to the bottom surface of the sponge, and the soft magnet is adsorbed and connected to the inner wall of the bottom end of the storage bin.

[0014] (2) Through the setting of the sponge, the friction force when the grinding balls roll inside the storage bin can be increased, further slowing down the material dropping rate of the grinding balls onto the conveyor, and reducing the impact force of the grinding balls on the conveyor.

[0015] (3) Through the setting of the lifting frame, when the motor is started, the movable rod can slide along the sliding slot under the screw thread structure when the screw rod rotates, thereby pushing and pulling the first material distribution rack, the hopper, the second material distribution rack and the discharge pipe as a whole by the lifting push rod, so as to adjust the position of the hopper according to the height of the discharge end of the elevator, so that the hopper can accurately receive materials.

[0021] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0022] Refer to Figures 1-3 As shown, a material distribution device for a grinding ball production line includes a conveyor 1;

[0023] After the grinding balls are annealed, the grinding balls can be directly fed onto the conveyor 1, so that the grinding balls are conveyed by the conveyor 1 to the next process section, which is convenient for the subsequent processing of the grinding balls.

[0024] However, when a large number of grinding balls are directly fed, most of the grinding balls will linearly impact the conveyor belt of the conveyor 1 under gravity. In the long run, it will seriously cause the conveyor belt to break and affect the service life of the conveyor 1.

[0025] Therefore, refer to Figure 1 As shown, it should be noted that it further includes a hopper 2 arranged above the conveyor 1 and a multi-path material distribution and feeding mechanism arranged between the hopper 2 and the conveyor 1;

[0026] The multi-path material distribution and feeding mechanism includes a first material distribution rack 3 integrally bent at an obtuse angle and two second material distribution racks 4. The first material distribution rack 3 is located below the discharge end of the hopper 2. The two second material distribution racks 4 are respectively fixedly connected to both ends of the first material distribution rack 3. Discharge pipes 5 are fixedly connected to both ends of the second material distribution rack 4. A storage bin 6 is inclined below the discharge pipe 5, and the lowest end of the storage bin 6 is located above the conveyor 1;

[0027] Through the setting of the multi-path material distribution and feeding mechanism, when feeding the grinding balls onto the conveyor 1, the operator can use the elevator to convey the grinding balls to the inside of the hopper 2. After the grinding balls are output from the discharge end of the hopper 2, they can be divided into two levels by the first material distribution rack 3 and the second material distribution rack 4 in sequence, and respectively fall into the four groups of storage bins 6. The grinding balls fall onto the conveyor 1 in a rolling manner due to the slope of the storage bin 6, thereby increasing the feeding path of the grinding balls, making the grinding balls non-linearly feed, reducing the feeding drop of the grinding balls, and reducing the impact of the grinding balls on the conveyor belt of the conveyor 1.

[0028] Furthermore, refer to Figure 1 And Figure 3 As shown, it should be noted that a sponge 14 is detachably arranged on the inner wall of the bottom end of the storage bin 6;

[0029] A soft magnet 15 is fixed on the bottom surface of the sponge 14, and the soft magnet 15 is adsorbed and connected to the inner wall of the bottom end of the storage bin 6;

[0030] Through the setting of the sponge 14, the friction force when the grinding balls roll inside the storage bin 6 can be increased, further slowing down the feeding rate of the grinding balls onto the conveyor 1 and reducing the impact force of the grinding balls on the conveyor 1;

[0031] Through the setting of the soft magnet 15, the sponge 14 is directly pulled, so that the soft magnet 15 is separated from the inner wall of the bottom end of the storage bin 6, and the disassembly of the sponge 14 can be quickly realized, so as to facilitate the replacement treatment when the sponge 14 is severely damaged.

[0032] Furthermore, referring to Figure 1 and Figure 2 as shown, it is worth noting that a lifting frame is provided between the first material distribution rack 3 and the conveyor 1;

[0033] The lifting frame includes two fixed brackets 7 symmetrically fixed on both sides of the top of the conveyor 1 and a movable rod 12 arranged between the two fixed brackets 7. A contraction groove 8 is opened at the end of the fixed bracket 7, and a lifting push rod 9 fixedly connected to the bottom surface of the first material distribution rack 3 slides inside the contraction groove 8. A sliding slot communicating with the inside of the contraction groove 8 is opened on the side of the fixed bracket 7, and the end of the movable rod 12 penetrates into the sliding slot and is fixedly connected to the lifting push rod 9;

[0034] A connecting rod 10 located below the movable rod 12 is fixed between the two fixed brackets 7. A motor 11 is installed on the connecting rod 10, and a screw rod 13 is fixed to the output end of the motor 11. The end of the screw rod 13 threadedly penetrates through the movable rod 12;

[0035] Through the setting of the lifting frame, when the motor 11 is started, the movable rod 12 can slide along the sliding slot under the screw thread structure when the screw rod 13 rotates, so as to push and pull the first material distribution rack 3, the hopper 2, the second material distribution rack 4 and the discharge pipe 5 as a whole, so as to adjust the position of the hopper 2 according to the height of the discharge end of the elevator, so that the hopper 2 can accurately receive materials.

[0036] Furthermore, referring to Figure 1 as shown, it is worth noting that support plates are vertically fixed on the front and back sides of the first material distribution rack 3, and the support plates are fixedly connected to the discharge end of the hopper 2;

[0037] Through the setting of the support plates, the hopper 2 can be conveniently fixedly connected to the first material distribution rack 3, ensuring the stable effect of the hopper 2 on the first material distribution rack 3.
