Description

Technical Field

[0001] This utility model relates to the field of wall sanding, specifically a wall sanding device for decoration. Background Technology

[0002] In the process of home renovation, wall sanding is an important step to ensure the smoothness of the wall surface. Currently, wall sanding mainly relies on manual operation, using tools such as sandpaper or sandpaper holders to sand by hand. This method is not only inefficient, but also makes it difficult to guarantee the sanding quality, and it also consumes a lot of human resources.

[0003] While some existing wall sanding equipment has achieved mechanized sanding, it often only allows for single-station operation, meaning it can only sand one area at a time, and the height adjustment is inconvenient, resulting in low sanding efficiency. Utility Model Content

The rear end of the output shaft of the motor 1 is fixedly connected to the front end of the rotating shaft. A slide rod is located on the left side of the lead screw. The top and bottom ends of the slide rod are fixedly connected to the bottom of the top plate and the top of the base plate, respectively. A grinding mechanism is located on the left side of the slide rod and the two guide rods. The grinding mechanism slides with the slide rod and the guide rods. The grinding mechanism is threaded with the lead screw.

[0007] The grinding mechanism includes a movable frame, which is box-shaped with an opening on the left. Guide blocks are fixedly connected to the front and rear sides of the right side wall of the movable frame. The two guide blocks are slidably sleeved on the outer walls of the two guide rods. A slider is fixedly connected to the middle of the right side wall of the movable frame. The slider is slidably sleeved on the outer wall of the slide rod. A ball nut is threaded onto the outer wall of the lead screw. The left side of the outer wall of the ball nut is fixedly connected to the right side wall of the slider. There are two grinding rollers on the inner side of the movable frame. The grinding rollers are distributed vertically. The left side of the outer wall of the grinding roller protrudes from the left opening of the movable frame. The front and rear ends of the grinding rollers are fixedly connected to support shafts.

[0008] The rear ends of the two rear support shafts extend through the rear side wall of the movable frame. The rear ends of the two rear support shafts are rotatably connected to the rear side wall of the movable frame. The rear ends of the two rear support shafts are fixedly connected to pulley one. Belt one is sleeved between the outer walls of the two pulleys one. Motor two is fixedly installed on the top front side of the movable frame. The two front support shafts are rotatably connected to the front side wall of the movable frame.

A rotating shaft 11 is rotatably connected to the top of the rear side wall of the fixed base 10. The rotating shaft 11 passes through the fixed base 10. A bevel gear 12 is fixedly connected to the rear end of the rotating shaft 11. The bevel gear 12 meshes with the bevel gear 9. A motor 13 is fixedly installed on the top front side of the base plate 1. The rear end of the output shaft of the motor 13 is fixedly connected to the front end of the rotating shaft 11. A slide rod 14 is provided on the left side of the lead screw 8. The top and bottom ends of the slide rod 14 are fixedly connected to the bottom of the top plate 7 and the top of the base plate 4, respectively. A grinding mechanism is provided on the left side of the slide rod 14 and the two guide rods 6. The grinding mechanism slides and engages with the slide rod 14 and the guide rods 6. The grinding mechanism is threaded with the lead screw 8.

[0021] The grinding mechanism includes a movable frame 15, which is box-shaped with an opening on the left. Guide blocks 16 are fixedly connected to the front and rear sides of the right side wall of the movable frame 15. The two guide blocks 16 are slidably sleeved on the outer walls of the two guide rods 6. A slider 17 is fixedly connected to the middle of the right side wall of the movable frame 15. The slider 17 is slidably sleeved on the outer wall of the slide rod 14. A ball nut 18 is threaded onto the outer wall of the lead screw 8. The left side of the outer wall of the ball nut 18 is fixedly connected to the right side wall of the slider 17. The inner side of the movable frame 15 has two grinding rollers 19, which are distributed vertically. The left side of the outer wall of the grinding roller 19 protrudes from the left opening of the movable frame 15. The front and rear ends of the grinding roller 19 are fixedly connected to the support shaft 20.

[0022] The rear ends of the two rear support shafts 20 extend through the rear side wall of the movable frame 15.

[0023] Both motor 13 and motor 23 are servo geared motors.

[0024] Connect the power supply and start motor 13 and motor 23.

[0025] The output shaft of motor 13 drives the rotating shaft 11 to rotate. Since the rear end of the rotating shaft 11 is fixedly connected to bevel gear 12, bevel gear 12 meshes with bevel gear 9, bevel gear 9 also rotates. Bevel gear 9 is fixed at the bottom of lead screw 8, so lead screw 8 starts to rotate.

[0026] The ball nut 18 is threaded onto the outer wall of the lead screw 8, so the ball nut 18 will move up and down as the lead screw 8 rotates. The left side of the outer wall of the ball nut 18 is fixedly connected to the right side wall of the slider 17, so the slider 17 will move up and down together with the ball nut 18.

[0027] The slider 17 is slidably sleeved on the outer wall of the slide rod 14, while the guide blocks 16, which are fixedly connected to the front and rear sides of the right side wall of the movable frame 15, are slidably sleeved on the outer walls of the two guide rods 6, ensuring the stability of the movable frame 15 moving up and down.

[0028] The output shaft of motor 23 drives a pulley 24 to rotate, and through belt 25, the support shaft 20 on the front side and the pulley 24 on it rotate together.

[0029] The support shaft 20 on the upper front side is fixedly connected to the grinding roller 19, so the grinding roller 19 begins to rotate.

[0030] Meanwhile, the rear ends of the two rear support shafts 20 are fixedly connected to pulleys 21, and belts 22 are sleeved between the outer walls of the two pulleys 21, so the two rear grinding rollers 19 will also rotate synchronously.

[0031] The operator moves the entire device back and forth using push rod 3, and the moving wheels 2 allow the device to slide easily on the ground, thus sanding the wall surface. This utility model only protects the mechanical parts; functions implemented through software control are not within the scope of protection of this utility model.
