The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1

[0030] Reference Figures 1-4 This utility model embodiment proposes a scraping structure for an elevator parts spraying device, including a placement platform 1, a protruding upper wing plate 11 on the top of the placement platform 1, and a three-phase motor 12 on one side of the outer wall of the placement platform 1. A ball screw 13 is provided at the output end of the three-phase motor 12, and a follow-up self-adjusting component 2 is provided on the ball screw 13.

[0031] The follow-up self-adjusting assembly 2 includes a movable frame 21 located on the outer wall of the ball screw 13. A spring 211 is installed at the bottom of the movable frame 21, and a vertical lifting platform 212 is installed at the top of the spring 211. A crossbar 22 is installed on one side of the outer wall of the vertical lifting platform 212. An infrared ranging sensor 221 is installed at one end of the top of the crossbar 22. The infrared ranging sensor 221 is a Hypersens HPS-167 single-point ToF ranging sensor. A cylinder 222 is installed on the outer wall of the crossbar 22, and a rotating sleeve 223 is fitted onto the outer circumference of the cylinder 222. The infrared ranging sensor 221 is located directly below the upper wing plate 11, and the rotating sleeve 223 is located outside the upper wing plate 11. Through the positioning of the infrared ranging sensor 221, the distance between the infrared ranging sensor and the upper wing plate 11 can be measured in real time, allowing the rotating sleeve 223 to contact the metal plate placed above the upper wing plate 11, thereby enabling the rotating sleeve 223 to... The metal plates are in full contact. An inclined bracket 23 is provided on the outer side wall of the movable frame 21. The cross-section of the inclined bracket 23 is "H". The H-shaped inclined bracket 23 can provide a position for the installation of the electric push rod 231 and form a moving limit structure after it cooperates with the inclined lifting platform 232 to ensure the stability of the inclined movement of the inclined lifting platform 232. An electric push rod 231 is provided on the inner side wall of the inclined bracket 23. The output end of the electric push rod 231 is provided with the inclined lifting platform 232. A scraping thickness adjustment component 3 is provided on the inclined lifting platform 232.

[0032] The thickness adjustment assembly 3 includes an adjustment frame 31 on one side of the outer wall of the inclined lifting platform 232. A screw 311 is threadedly connected to the top center of the adjustment frame 31. A handwheel 313 is provided at the top of the screw 311, and an adjustment platform 312 is rotatably connected to the bottom of the screw 311. The cross-sections of the vertical lifting platform 212, the adjustment platform 312, and the inclined lifting platform 232 are all "I" shaped. The "I" shaped vertical lifting platform 212, the adjustment platform 312, and the inclined lifting platform 232 give them limiting capabilities, thereby ensuring the stability of the movement of the vertical lifting platform 212, the adjustment platform 312, and the inclined lifting platform 232. A scraper roller 5 is rotatably connected to one side of the outer wall of the adjustment platform 312.

[0033] Specifically, during the smoothing operation of the coating on the metal sheet, the metal sheet is placed on top of the upper wing plate 11. Under the pressure of the metal sheet, it squeezes the rotating sleeve 223 and moves it downward. The crossbar 22 pulls the vertical lifting platform 212 to move vertically downward simultaneously, and the spring 211 is compressed. At this time, the infrared ranging sensor 221 measures the distance between itself and the upper wing plate 11 and sets it as the initial value. Then, the position of the scraper roller 5 is adjusted according to the thickness of the metal sheet and the thickness of the coating to be applied after spraying. During adjustment, the handwheel 313 is turned. Handwheel 313 pulls screw 311 to rotate. Through the threaded connection between screw 311 and adjustment frame 31, the bottom end of screw 311 pulls adjustment table 312 to rise and fall vertically, thereby adjusting the height position of scraper roller 5. After the position adjustment of scraper roller 5 is completed, control three-phase motor 12 to drive ball screw 13 to rotate through one of its output ends. The moving frame 21 on ball screw 13 moves horizontally and linearly on the placement platform 1. At this time, follow-up self-adjusting component 2, scraping thickness adjustment component 3 and scraper roller 5 move synchronously, and scraper roller 5 performs scraping operation on the coating on metal plate.

[0034] As the scraper roller 5 moves, when the metal sheet becomes curved, the rotating sleeve 223 contacts the curved part first. At this time, the pressure on the rotating sleeve 223 decreases. Under the action of the spring 211's rebound force, the spring 211 pushes the vertical lifting platform 212 and the crossbar 22 to move upward. The distance value between the infrared ranging sensor 221 and the upper wing plate 11 changes and becomes a variable value. At this time, the output end of the electric push rod 231 is controlled by the external control system to extend beyond this variable value. The electric push rod 231 drives the tilting lifting platform 232 to move upward along the tilting bracket 23 through its output end on one side, thereby causing the scraper roller 5 to move a corresponding distance. This ensures that the distance value between the scraper roller 5 and the metal sheet is always at a constant value, thus ensuring the uniformity of the coating after it is scraped flat on the metal sheet.

[0035] Example 2

[0036] Reference Figures 1-2Based on the above embodiments, this utility model embodiment also proposes a scraping structure for an elevator parts spraying device, including an adjustment platform 312. A side support plate 314 is provided on the outer wall of the adjustment platform 312 adjacent to the scraper roller 5. A through groove is provided on the outer wall of the adjustment frame 31 for the side support plate 314 to move, so that the side support plate 314 can move together with the adjustment platform 312, thereby adjusting the position of the sweeping roller 44 and the baffle 42. A desludge removal component 4 is provided on the side support plate 314. The desludge removal component 4 includes a support column 41 provided on the top of the side support plate 314. A baffle 42 is provided at the top of the support column 41. A drive motor 43 is provided on the outer wall of the side support plate 314. A sweeping roller 44 is provided at the output end of the drive motor 43. A scraping groove 441 is provided on the outer circumferential surface of the sweeping roller 44.

[0037] Specifically, to prevent the paint from accumulating on one side of the scraper roller 5 during the paint leveling operation, thus increasing the resistance of the leveling operation, a portion of the paint on one side of the scraper roller 5 is removed by the descaling component 4. When the scraper roller 5 is leveling the metal sheet, the drive motor 43 drives the sweeping roller 44 to rotate through its output end. During the rotation of the sweeping roller 44, the scraping groove 441 contacts the accumulated paint and scrapes it in. As the sweeping roller 44 rotates, the paint in the scraping groove 441 is thrown out and flows along the baffle 42. The continuous rotation of the sweeping roller 44 cleans the excess paint in the forward direction of the scraper roller 5, reducing the resistance to the leveling operation, ensuring the smooth progress of the leveling operation, and improving the efficiency of the leveling operation.
