[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To achieve the above-mentioned utility model objectives, such as Figures 1-4As shown, this utility model provides a high-efficiency rust removal and grinding device for stainless steel composite pipes, including a shell 1. A handle 2 is connected to the upper end of the shell 1, and tensioning slides 3 are provided on both the left and right sides of the lower end of the shell 1. A grinding belt 4 is sleeved on the outside of the two tensioning slides 3 and rotatably connected to the grinding belt 4. A steel pipe 5 is provided at the lower end of the grinding belt 4. During the rust removal and grinding process on the outer wall of the stainless steel composite pipe, the rust removal and grinding device is picked up by the handle 2 and the device is started, so that the grinding belt 4 rotates at high speed outside the two tensioning slides 3. Then, the handle 2 is pressed down to... The lower end of the grinding belt 4 is pressed against the outer wall of the steel pipe 5 and is perpendicular to the axis of the steel pipe 5. The grinding belt 4 can be recessed by sliding the two tensioning slides 3 at the lower end of the outer shell 1 and fit tightly against the arc-shaped outer wall of the steel pipe 5. Through the high-speed friction between the grinding belt 4 and the outer wall of the steel pipe 5, the outer wall of the steel pipe 5 is ground. This allows the grinding belt 4 to grind the outer wall of the steel pipe 5 by deforming a large area at the lower end, thus improving the rust removal efficiency. Moreover, the grinding belt 4 can remove rust from steel pipes 5 of different diameters by deforming the outer wall of the steel pipe 5, thus improving the adaptability.
[0028] Preferably, the lower end of the outer shell 1 is provided with an adjustment groove 6, and the upper end of the tensioning slide 3 is engaged inside the adjustment groove 6 and slidably connected to the adjustment groove 6. Support gears 7 are rotatably connected inside both the upper and lower ends of the tensioning slide 3. Gear grooves are formed on the cylindrical outer wall of the support gear 7, and a grinding belt 4 is engaged inside the gear grooves and meshes with the support gear 7 through the gear grooves. The grinding belt 4 is rotatably connected to the outside of the tensioning slide 3 through the support gear 7, and the upper end of the grinding belt 4 is located inside the adjustment groove 6. A tensioning seat 8 is connected to the center of the lower end of the outer shell 1. A limiting slide tube 9 and a limiting slide rod 10 pass through the tensioning seat 8 on the left and right sides respectively. The limiting slide tube 9 is connected to the tensioning slide 3 on the right side, and the limiting slide rod 10 is connected to the tensioning slide 3 on the left side and slidably connected inside the limiting slide tube 9. Tensioning springs 1 are sleeved on the outside of both the limiting slide tube 9 and the limiting slide rod 10. 1. The two tension springs 11 are located between the tension seat 8 and the two tension slides 3 respectively. During the process of the lower end of the grinding belt 4 being concave, the lower end of the grinding belt 4 is pushed by the outer wall of the steel pipe 5, causing the lower end of the grinding belt 4 to bend and concave upward. At this time, the two tension slides 3 slide inward at the lower end of the outer shell 1 through the adjustment groove 6, and adjust the length between the upper and lower ends of the grinding belt 4 through the support gear 7. The length of the upper end of the grinding belt 4 is shortened and the length of the lower end of the grinding belt 4 is lengthened, so that both the upper and lower ends of the grinding belt 4 are in a taut state, so that the lower end of the grinding belt 4 can be smoothly concave upward and tightly fit with the outer wall of the steel pipe 5, and increase the release area between the grinding belt 4 and the steel pipe 5. At the same time, the grinding belt 4 can be limited to the outside of the two tension slides 3 by the four support gears 7, and rotate at high speed outside the tension slides 3.
[0029] Among them, the two tensioning slides 3 can tighten the grinding belt 4 through the two tensioning springs 11 between them and the tensioning seat 8, and limit the two tensioning springs 11 through the limiting slide tube 9 and the limiting slide rod 10, so that the grinding belt 4 can always be kept in a taut state, ensuring that the grinding belt 4 can always be tightly engaged with the four support gears 7, and ensuring that the grinding belt 4 can always be tightly attached to the outer wall of the steel pipe 5, thus ensuring the stable transmission of the grinding belt 4.
[0030] Preferably, the upper end of the tensioning seat 8 has a connecting slide groove 12 running through it on both sides. A connecting gear 13 is rotatably connected to the center of the connecting slide groove 12. Both ends of the connecting gear 13 are provided with connecting racks 14, which mesh with each other. Both connecting racks 14 are slidably connected inside the connecting slide groove 12. The two connecting racks 14 are respectively connected to the two tensioning slides 3. During the process of the tensioning slides 3 sliding inward, the two tensioning slides 3 are connected by the connecting gear 13 and the connecting racks 14. Since the connecting gear 13 meshes between the two connecting racks 14, and the two connecting racks 14 are respectively connected to the two tensioning slides 3, the two tensioning slides 3 can slide inward at the same interval, so that the two tensioning slides 3 always remain symmetrical at the lower end of the outer shell 1. This ensures that the grinding belt 4 is always located directly below the outer shell 1, ensures that the downward pressure of the handle 2 on the grinding belt 4 is uniform, and ensures that the grinding force of the grinding belt 4 on the steel pipe 5 is uniform.
[0031] Preferably, a drive gear 15 is rotatably connected to the center of the adjustment groove 6, and the drive gear 15 meshes inside the upper end of the grinding belt 4. The rear end of the drive gear 15 is connected to a drive motor 16 via a motor shaft. The drive motor 16 is connected to the outer wall of the rear end of the housing 1. A pressure roller groove 17 is connected to the center of the upper end of the adjustment groove 6, and a clamping pressure roller 18 is rotatably connected inside the pressure roller groove 17. The clamping pressure roller 18 is in contact with the upper end of the grinding belt 4 and clamps the grinding belt 4 with the drive gear 15. During the start-up process of the equipment, the starting... The drive motor 16 drives the drive gear 15 to rotate via the motor shaft. Since the center of the upper end of the grinding belt 4 is clamped between the drive gear 15 and the clamping pressure roller 18 and meshes with the drive gear 15, the drive gear 15 can drive the grinding belt 4 to move to one side inside the adjustment groove 6 and rotate outside the two tensioning slides 3 through the four support gears 7, thereby providing power for the high-speed rotation of the grinding belt 4. The grinding belt 4 can be stably connected to the drive gear 15 by the squeezing of the clamping pressure roller 18.
[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
