The knocking block shakes off the smaller powder through the vibration generated by knocking the grinding roller, keeping the grinding roller clean. This can prevent the powder layer from hindering the direct contact between the grinding roller and the fresh material, resulting in reduced grinding efficiency, thereby improving the grinding efficiency. It can also prevent the powder attached to the grinding roller from deteriorating due to moisture, oxidation, etc., which in turn affects the quality of the ground powder. At the same time, all the ground powder can be poured into the mixing box to ensure the initial ratio of raw materials for cable production and improve product quality.

[0025] 2. Through the setting of the mixing mechanism, the second motor and the cylinder are used in conjunction. The second motor drives the stirring blade to stir the material, and the cylinder drives the stirring blade to deflect back and forth to a certain extent. This can more effectively break the interfacial tension between the materials, promote the mutual penetration and mixing between the materials, and produce more complex fluid dynamics effects, making the flow of materials in the mixing tank more uniform and sufficient, thereby improving the mixing quality and efficiency. It can also destroy the mixing isolation zone in the mixing tank, strengthen the axial circulation flow of the fluid, and further improve the mixing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The stirring assembly includes a connecting frame 2 602, a motor 2 603, a rotating shaft 2 604 and a connecting piece 605; the connecting frame 2 602 is arranged on the inner side of the mixing box 8, the motor 2 603 is arranged at the end of the connecting frame 2 602 away from the mixing box 8, the rotating shaft 2 604 is arranged at the output end of the motor 2 603, the outer side of the rotating shaft 2 604 is provided with a slide groove 611, the connecting piece 605 is arranged on the outer side of the rotating shaft 2 604, and there are multiple connecting pieces 605 arranged in a ring shape. A fixed shaft 606 is rotatably provided on the side of the connecting piece 605 away from the rotating shaft 2 604, and a stirring blade 607 is provided on the outer side of the fixed shaft 606. When the motor 2 603 is started, the motor 2 603 drives the rotating shaft 2 604 to rotate, and the rotating shaft 2 604 drives the fixed shaft 606 to rotate through the connecting piece 605, and the fixed shaft 606 drives the stirring blade 607 to rotate, thereby stirring the powder and liquid reagent in the mixing box 8. The self-rotating assembly includes a cylinder 601, a push rod 612, a moving ring 613 and a fixed block 614; the cylinder 601 is arranged at the bottom of the mixing box 8, the push rod 612 is arranged at the output end of the cylinder 601, the moving ring 613 is arranged on the outside of the push rod 612, the connection between the moving ring 613 and the push rod 612 is in the slide groove 611, and is slidably connected to the slide groove 611, so that when the rotating shaft 604 rotates, the push rod 612 can be driven to rotate by the moving ring 613, the fixed block 614 is arranged on the top of the moving ring 613, and the side of the fixed block 614 is rotatably provided with a rotating rod 610, and the end of the rotating rod 610 away from the fixed block 614 is rotatably provided with a fixed block One 609, a mounting plate 608 is provided at one end of the fixed block 609 away from the rotating rod 610, and the inner side of the mounting plate 608 is connected to the end of the fixed shaft 606.
