Description

Technical Field

[0001] This utility model relates to the field of material coating preparation technology, specifically to a device for preparing wear-resistant composite material coatings. Background Technology

[0002] In the fields of industrial equipment manufacturing and mechanical parts protection, wear-resistant composite material coatings are widely used because they can significantly improve the wear resistance of workpiece surfaces and extend service life. However, in the preparation process of wear-resistant composite material coatings, the quality control of the raw material pretreatment process directly affects the performance and stability of the final coating.

[0003] In the raw material feeding stage, traditional preparation equipment often lacks an effective raw material screening and dispersing structure. During storage or transportation, wear-resistant composite material raw materials are prone to agglomeration due to factors such as changes in environmental humidity and compression. At the same time, large particle impurities may be mixed in. If such raw materials are directly fed into subsequent processes, it will lead to uneven particle size, resulting in local differences in wear resistance after coating formation. For example, some areas may have voids due to excessively large particles, reducing the density of the coating, or uneven particle distribution may lead to surface defects, seriously affecting the overall protective effect and service life of the coating, and failing to meet the stringent requirements for coating quality in high wear-resistant scenarios.

The outer wall of the cams 18 is slidably connected to the outer wall of the top of the support ring plate 13 and the outer wall of the bottom of the screen plate 15. The inner wall of the drive motor 19 is rotatably connected to the outer wall of the rotating shaft 17. When the drive motor 19 is started, it drives the rotating shaft 17 to rotate, causing the cams 18, which are symmetrically fixed on the rotating shaft 17, to rotate synchronously. When the cams 18 rotate, their outer walls slide in contact with the bottom of the screen plate 15. Together with the slide rods 14 and the compression springs 16 sleeved on the outside of the slide rods 14, the screen plate 15 is pushed to slide up and down along the slide rods 14. The vibrating screen plate 15 screens the raw materials.

[0021] The conveying structure 2 includes a support base 21, a conveying cylinder 22 is fixedly connected to the inner wall of the top of the support base 21, a conveying motor 23 is fixedly connected to the outer wall of the side of the conveying cylinder 22, and a spiral conveying rod 24 is rotatably connected to the inner wall of the conveying motor 23.

[0022] The outer wall of the screw conveyor 24 is slidably connected to the inner wall of the conveying cylinder 22. The inner wall of the top of the conveying cylinder 22 is fixedly connected to the outer wall of the bottom of the hopper 11. When the motor 23 is started, it drives the screw conveyor 24 to rotate inside the conveying cylinder 22. The screened raw material falling from the feeding structure 1 enters the conveying cylinder 22. The screw conveyor 24 pushes the raw material stably along the axial direction of the conveying cylinder 22 to the stirring structure 3 through the rotation of the screw blades.

[0023] The stirring structure 3 includes a stirring tank 31. An opening and closing plate 32 is slidably connected to the inner wall of the bottom of the stirring tank 31. A drive shaft 33 is rotatably connected to the inner wall of the stirring tank 31. A stirring blade 34 is fixedly connected to the outer wall of the drive shaft 33. A servo motor 35 is rotatably connected to the outer wall of the drive shaft 33.

[0024] The stirring blade 34 is set inside the stirring tank 31. The outer wall of the stirring tank 31 is fixedly connected to the outer wall of the conveying cylinder 22 on the side away from the conveying motor 23. The interior of the stirring tank 31 is connected to the interior of the conveying cylinder 22. The servo motor 35 is started, driving the drive shaft 33 to rotate inside the stirring tank 31. The stirring blade 34 fixed on the drive shaft 33 rotates with it, and the raw materials entering the stirring tank 31 are fully mixed under the stirring of the stirring blade 34.

[0025] In use, the material is poured into the feeding structure 1, and the material is sent to the conveying structure 2 by the sieving and dispersing. The material is then conveyed to the stirring structure 3 by the conveying structure 2 for the composite material coating preparation process. The composite material raw material to be processed is fed into the feed port 12 at the top of the feed hopper 11. The drive motor 19 is started, which drives the rotating shaft 17 to rotate. This causes the cams 18, which are symmetrically fixed on the rotating shaft 17, to rotate synchronously. When the cams 18 rotate, their outer walls slide in contact with the bottom of the screen plate 15. In conjunction with the slide rod 14 and the compression spring 16 sleeved on the outside of the slide rod 14, the screen plate 15 is pushed to slide up and down along the slide rod 14. The vibrating screen plate 15 screens the raw material, removes lumps or large particles of impurities, and ensures that the raw material entering the subsequent structure has a uniform particle size. At the same time, the vibration prevents the raw material from accumulating and clogging on the screen plate 15. The screened raw material falls into the conveying structure 2 through the inner space of the support ring plate 13. When the conveyor motor 23 starts, it drives the screw conveyor 24 to rotate inside the conveyor cylinder 22. The screened raw material falling from the feeding structure 1 enters the conveyor cylinder 22. The screw conveyor 24 pushes the raw material along the axial direction of the conveyor cylinder 22 to the mixing structure 3 through the rotation of the screw blades. The conveyor cylinder 22 is fixed on the support base 21 to ensure the structural stability of the conveying process. The screw conveying method can accurately control the amount of raw material conveyed and avoid material interruption or accumulation. The servo motor 35 starts, driving the drive shaft 33 to rotate inside the mixing tank 31. The stirring blade 34 fixed on the drive shaft 33 rotates with it. The raw materials entering the mixing tank 31 are fully mixed under the stirring of the stirring blade 34, ensuring that the components of the composite material are evenly dispersed. After the mixing is completed, the material discharge channel is opened by controlling the sliding of the opening and closing plate 32 at the bottom of the mixing tank 31, and the evenly mixed raw materials are discharged to the subsequent coating forming equipment, completing the pretreatment process of the coating raw materials.
