DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] An embodiment of the present utility model provides a powder scraping device for a spar powder conveyor belt.

[0025] Please refer to Figures 1 to 4, including a support mechanism provided at the bottom of the transmission device 1. The bottom of the transmission device 1 is in contact connection with a straight scraper 2 and two inclined scrapers 3. One corner of one side of the inclined scraper 3 is rotatably connected to one corner of one side of the straight scraper 2. Two mirror-image arc-shaped grooves 16 are provided on one side of the straight scraper 2. A slider 11 is slidably connected in the arc-shaped groove 16. The slider 11 is fixedly connected to one side of the inclined scraper 3. A limiting component for limiting the sliding of the slider 11 in the arc-shaped groove 16 is provided on the straight scraper 2. A fixing component for stabilizing the straight scraper 2 is provided on the transmission device 1;

[0026] When the belt 103 on the transmission device 1 rotates, the surface of the belt 103 will contact the straight scraper 2 and the end of the inclined scraper 3. The powder attached to the surface of the belt 103 is cleaned or scraped off by the cooperation of the inclined scraper 3 and the straight scraper 2;

[0027] According to the angle formed by the inclined roller causing the edge of the belt 103 to be inclined, the inclined position of the inclined scraper 3 is adjusted accordingly, so as to facilitate the inclined scraper 3 to be parallel to the inclined surface of the belt 103 and make the inclined surface of the belt 103 contact the end of the inclined scraper 3, so as to facilitate cleaning the powder attached to the inclined surface of the belt 103; By rotating the inclined scraper 3, the inclined scraper 3 slides in the cavity of the arc-shaped groove 16 through the slider 11.

[0028] Please refer to Figure 3 , the limiting component includes a second threaded rod 14 and a rotating rod 13. One end of the second threaded rod 14 is fixedly connected with a first connecting block. One end of the rotating rod 13 is rotatably connected with a second connecting block. One side of the two inclined scrapers 3 is respectively rotatably connected with one side of the first connecting block and one side of the second connecting block. The other end of the second threaded rod 14 is in threaded connection with the threaded groove provided at the other end of the rotating rod 13;

[0029] By rotating the rotating rod 13, the rotating rod 13 drives the two inclined scrapers 3 to move in opposite or relative directions to each other through the second threaded rod 14, so as to facilitate adjusting the inclined angles of the two inclined scrapers 3 at the same time.

[0030] Please refer to Figure 3 , wire rods 12 are slidably sleeved on the outer sides of the second threaded rod 14 and the rotating rod 13. Two wire grooves 15 are provided on one side of the straight scraper 2. The two wire grooves 15 are respectively slidably connected with the two wire rods 12;

[0031] The sliding connection between the wire groove 15 and the wire rod 12 facilitates limiting the rotating rod 13 to prevent the rotating rod 13 from tilting, and thus the angles of the two inclined scrapers 3 mirroring each other can be the same. Among them, the two wire rods 12 are fixedly connected to each other; The rotating rod 13 and the second threaded rod 14 can slide and rotate in the wire rod 12.

[0032] Please refer to Figure 1, the transmission device 1 includes a transmission frame 102, a belt 103, a driving roller and a driven roller. The belt 103 is sleeved between the driving roller and the driven roller. Both the driving roller and the driven roller are rotatably connected to both ends of the transmission frame 102. Linear array-distributed support rods 101 are fixedly connected to both side edges at the bottom of the transmission frame 102. A servo motor for driving the driving roller to rotate is provided on the transmission frame 102. The upper ends of the straight scraper 2 and the two inclined scrapers 3 are both in contact with the side wall of the belt 103;

[0033] The servo motor is electrically connected to the power supply. The driving roller is driven to rotate by the movable shaft of the servo motor, and the driving roller drives the belt 103 to rotate. Among them, a straight roller and an inclined roller are also provided on the transmission frame 102, so as to limit the position of the belt 103, thereby causing the two side edges of the belt 103 to be inclined;

[0034] There is no specific limitation on the model of the servo motor, which is subject to the equipment for adaptation.

[0035] Please refer to Figure 2 , the fixing component includes a fixing frame 6 and a lifting rod 4. The fixing frame 6 is in contact connection between the two support rods 101. A first threaded rod 5 and a second long rod 9 are fixedly connected to the bottom of the lifting rod 4. Two fixing ports for sliding connection with the end of the first threaded rod 5 and the second long rod 9 are respectively opened in the upper part of the fixing frame 6. A threaded ring 10 is sleeved on the outside of the first threaded rod 5, and the threaded ring 10 is rotatably connected to the upper part of the fixing frame 6;

[0036] By rotating the threaded ring 10, the threaded ring 10 drives the lifting rod 4 to lift and lower by means of the first threaded rod 5.

[0037] Please refer to Figure 3 , a buffer plate 17 is fixedly connected to the bottom of the straight scraper 2. Linear array-distributed buffer rods 8 are fixedly connected to the bottom of the buffer plate 17. Buffer grooves for sliding connection with the buffer rods 8 are respectively opened at the corresponding positions of the lifting rod 4 relative to each buffer rod 8. A spring is slidably sleeved on the outside of the buffer rod 8, and the spring is located between the buffer plate 17 and the lifting rod 4;

[0038] The buffer plate 17 forms a buffer through the spring. While facilitating the straight scraper 2 to clean the powder attached to the rotating surface of the belt 103, it can also reduce the extrusion force and friction force of the straight scraper 2 on the surface of the belt 103.

[0039] Please refer to Figure 1 , a collection box 7 is arranged below the transmission device 1. The collection box 7 is located directly below the straight scraper 2, and the straight scraper 2 is inclined;

[0040] The cleaned powder will fall into the collection box 7 along the inclined surface of the straight scraper 2 for unified collection.
