DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] Example 1: Reference Figure 1-6 , a surface spraying device for rust prevention of metal doors and windows, comprising a stand 1, and also comprising:

[0041] A first support 2, the first support 2 is connected to the stand 1 through a support plate 101, and a first positioning component for positioning the door and window body 4 is provided on the first support 2;

[0042] A track plate 3, on which a track groove 301 is formed, and a paint spraying assembly is movably connected at the track groove 301;

[0043] A pushing component, which is arranged at the lower side of the stand 1 and placed at the bottom of the first support 2, and is used to push the door and window body 4 upward; and

[0044] A rotating assembly, which is arranged on the upper side of the stand 1 and placed on the top of the first support 2, and is used to drive the paint spraying assembly to move along the track groove 301;

[0045] Wherein, a transmission component is arranged between the rotating component and the pushing component.

[0046] Specifically, when the door and window body 4 is sprayed, the door and window body 4 is placed in the first support 2 and clamped and positioned by the first positioning component, and then the rotating component is controlled to operate, and the rotating component drives the paint spraying component to move along the track groove 301. When the rotating component is working, the transmission component drives the pushing component to move, so that the pushing component drives the door and window body 4 to move upward in the first support 2, and then the surrounding side and the upper and lower sides of the door and window body 4 are sprayed. The all-round painting of the door and window body 4 can be achieved in a single time, and there is no need to re-position the door and window body 4 for re-painting, thereby ensuring the efficiency of the painting of the door and window body 4, and avoiding the occurrence of uneven or stacked paint during manual spraying, which greatly reduces the labor intensity of workers and has a high degree of automation.

[0047] Example 2: Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7, a surface spraying device for rust prevention of metal doors and windows. On the basis of Example 1, further, the rotating component includes a driving motor 5 fixedly mounted on the top of the stand 1, the output shaft of the driving motor 5 is connected to the driving shaft 501, a telescopic plate 502 is fixedly arranged on the outer side of the driving shaft 501, and the end of the telescopic plate 502 away from the driving shaft 501 is connected to a connecting rod 503, and a sliding rod 504 movable in a track groove 301 is arranged at the bottom of the connecting rod 503, and the paint spraying component is arranged on the connecting rod 503.

[0048] Specifically, when the rotating component is working, the driving motor 5 is controlled to run, and the output shaft of the driving motor 5 drives the driving shaft 501 to rotate. The driving shaft 501 drives the connecting rod 503 to rotate through the telescopic plate 502. The sliding rod 504 at the bottom of the connecting rod 503 slides in the track groove 301. The telescopic plate 502 is free to expand and contract during this period, so that the paint spraying component on the outside of the connecting rod 503 moves around the door and window body 4 to achieve uniform spraying on the door and window body 4. The track groove 301 is set to an elliptical shape but is not limited to this shape. The specific shape setting of the track groove 301 should match the door and window body 4, so that the distance between the paint spraying component and the door and window body 4 is as close as possible when rotating around the door and window body 4.

[0049] Example 3: Reference Figure 7 , Figure 8 and Fig.11 , a surface spraying device for rust prevention of metal doors and windows, based on Example 2, further, the paint spraying assembly includes a sleeve 6 arranged on the outside of the connecting rod 503, the sleeve 6 slides on the track plate 3, and two limit rods 605 are arranged on the outside of the sleeve 6, a side plate 601 is arranged on the outside of the sleeve 6, a paint box 602 is connected to the side plate 601, the paint box 602 is connected to a material guide pipe 603 through a valve, a paint spray gun head 604 is arranged at one end of the material guide pipe 603 away from the paint box 602, and the paint spray gun head 604 is arranged on the sleeve 6.

[0050] Specifically, when the paint spraying assembly is working, the paint spray gun head 604 works and draws paint from the paint spray box 602 through the material guide tube 603, and then sprays the door and window body 4 while moving with the sleeve 6 and the connecting rod 503. The limit rod 605 set at the bottom of the sleeve 6 can limit the moving direction of the sleeve 6.

[0051] Example 4: Reference Figure 7 and Fig.11, a surface spraying device for rust prevention of metal doors and windows, based on Example 3, further, a moving rod 7 is slidably connected to the outer side of the sleeve 6, one end of the moving rod 7 is connected to the limiting plate 701, and a first elastic element 702 is sleeved on the outer side of the moving rod 7 with two ends respectively connected to the limiting plate 701 and the sleeve 6, a connecting plate 703 is fixed to the outer side of the moving rod 7, a paint spray gun head 604 is arranged on the connecting plate 703, and a first ball 704 is connected to the end of the moving rod 7 away from the limiting plate 701.

[0052] Specifically, when spraying most of the door and window bodies 4 (doors and windows with only outer metal frames), the moving rod 7 and the sleeve 6 are fixed and limited by the pin shaft; when spraying the door panel made of all metal, the restriction between the sleeve 6 and the moving rod 7 is released, and the moving rod 7 is pulled by the elastic force of the first elastic element 702, and the first ball 704 at the end of the moving rod 7 abuts against the all-metal door panel. As the sleeve 6 moves along the track groove 301 with the connecting rod 503, the moving rod 7 moves around the door and window body 4, and the first ball 704 at the end of the moving rod 7 is always in abutment with the metal door panel, thereby fixing the distance between the paint gun head 604 on the outer connecting plate 703 of the moving rod 7 and the all-metal door panel, so that the spraying distance between the paint gun head 604 and the all-metal door panel is always basically the same, thereby ensuring that the paint gun head 604 sprays the door and window body 4 evenly.

[0053] Example 5: Reference Figure 7 , Figure 8 and Fig.11 , a surface spraying device for rust prevention of metal doors and windows, based on Example 4, further, a driven gear 5041 is fixedly provided at the bottom of the sliding rod 504, and an in-groove rack 3011 meshing with the driven gear 5041 is provided in the track groove 301, the connecting rod 503 is rotatably connected to the telescopic plate 502 and the sleeve 6, a first missing gear 5031 is provided on the connecting rod 503, and a first sub-gear 8 meshing with the first missing gear 5031 is rotatably connected on the sleeve 6, a first winding rod 801 is provided on the first sub-gear 8, a first pull rope 802 is wound around the first winding rod 801 and connected, and one end of the first pull rope 802 away from the first winding rod 801 is connected to the paint spray gun head 604, and the paint spray gun head 604 is rotatably connected to the connecting plate 703 through a pin shaft, and a first torsion spring for resetting and rotating the paint spray gun head 604 is sleeved on the pin shaft.

[0054] Specifically, when the driving shaft 501 drives the connecting rod 503 to rotate by using the telescopic plate 502, the driven gear 5041 on the lower side of the sliding rod 504 moves with the connecting rod 503, and the driven gear 5041 is meshed with the rack 3011 in the groove of the track groove 301 for transmission. The driven gear 5041 drives the connecting rod 503 to rotate through the sliding rod 504. When the connecting rod 503 rotates, the first missing gear 5031 on the outer side is meshed with the first sub-gear 8 on the first winding rod 801 for transmission. The first winding rod 801 winds up the first pull rope 802. When the first missing gear 5031 is no longer meshed with the first sub-gear 8, the first winding rod 801 is reset. Rotate, the first pull rope 802 is released, so that the first pull rope 802 reciprocates and pulls one end of the paint spray gun head 604, so that the paint spray gun head 604 rotates on the connecting plate 703 with the pin as the center, so that the paint spray gun head 604 can swing back and forth along the side of the door and window body 4, and then spray the top and bottom walls of the door and window body 4, so as to avoid the paint spray gun head 604 spraying the door and window body 4 in a single direction, and failing to effectively spray the top or bottom of the door and window body 4, so as to realize the all-round painting of the door and window body 4 in a single time, without the need to disassemble the door and window body 4 for repainting, thereby ensuring the painting efficiency of the door and window body 4.

[0055] Example 6: Reference Figure 7 , Figure 8 and Fig.11 , a surface spraying device for rust prevention of metal doors and windows, based on Example 5, further, a fan 9 is fixedly provided on the sleeve 6, an electric heating element is provided in the fan 9, the input shaft of the fan 9 is connected to a driven bevel gear 901, and a driving bevel gear 5032 meshing with the driven bevel gear 901 is provided on the connecting rod 503.

[0056] Specifically, when the connecting rod 503 rotates, the outer active bevel gear 5032 meshes with the driven bevel gear 901 on the input shaft of the fan 9, so that the fan 9 runs and directs the hot air generated by the internal electric heating element to the sprayed door and window body 4 for drying, so that the paint layer dries quickly, thereby improving the overall processing progress of the door and window body 4, allowing the door and window body 4 to quickly enter the next processing procedure or be put into use, thereby improving the processing efficiency of metal doors and windows.

[0057] Example 7: Reference Figure 1-10 , a surface spraying device for anti-rust treatment of metal doors and windows, based on Example 6, further, the pushing component includes a screw 10 rotatably connected to the lower side of the frame 1, the outer side of the screw 10 is threadedly connected to a sleeve 1001, the outer side of the sleeve 1001 is connected to a connecting plate 1002, the end of the connecting plate 1002 away from the sleeve 1001 is connected to a sliding seat 1003, the sliding seat 1003 is slidably connected to a sliding table 1004, and both sides of the sliding table 1004 are provided with L-shaped plates 1005 that are movably against the door and window body 4.

[0058] Furthermore, a rotating rod 11 is rotatably connected to the bottom of the slide 1003, and a guide groove 111 is opened along the axial direction of the rotating rod 11. The rotating rod 11 is slidably connected to the screw 10, and a guide bar 12 matching the guide groove 111 is opened in the screw 10. A second missing gear 112 is arranged on the rotating rod 11, and second sub-gears 13 meshing with the second missing gear 112 are rotatably connected to both sides of the slide 1003. A second winding rod 131 rotatably connected to the slide 1003 is arranged on the second sub-gear 13, and a second torsion spring is arranged between the second winding rod 131 and the slide 1003. A second pull rope 132 is wound around the second winding rod 131, and the ends of the two second pull ropes 132 away from the second winding rod 131 are respectively connected to one side of the slide 1004.

[0059] Furthermore, the transmission assembly includes a transmission rod 14 rotatably connected to the stand 1, a first synchronous wheel 15 is provided on the top of the transmission rod 14 and the drive shaft 501, a first synchronous belt is provided between the two first synchronous wheels 15, a second synchronous wheel 16 is provided on the bottom of the transmission rod 14 and the screw 10, and a second synchronous belt is provided between the two second synchronous wheels 16.

[0060] Specifically, when the rotating assembly is working, the driving shaft 501 drives the transmission rod 14 to rotate through the first synchronous wheel 15 and the first synchronous belt, and the transmission rod 14 drives the screw 10 to rotate through the second synchronous wheel 16 and the second synchronous belt. When the screw 10 rotates, the sleeve 1001 connected with the outer thread moves up, the sleeve 1001 drives the connecting plate 703 to move up, the connecting plate 703 drives the slide seat 1003 and the slide table 1004 to move up, and the door and window body 4 supported on the L-shaped plate 1005 is lifted up. During this period, the screw 10 drives the rotating rod 11 to rotate through the guide bar 12, and the second missing gear 112 on the rotating rod 11 and the second winding rod 13 are connected. The second sub-gear 13 on 1 is intermittently meshed, so that when one of the second winding rods 131 on both sides of the slide 1003 winds up the second pull rope 132 connected thereto, the other second winding rod 131 releases the second pull rope 132 connected thereto, thereby realizing that the slide 1004 drives the L-shaped plate 1005 to move back and forth left and right relative to the slide 1003, so that the L-shaped plate 1005 will not always block a certain position at the bottom of the door and window body 4, so that the paint spray gun head 604 can spray the bottom support position of the door and window body 4, avoiding the occurrence of spraying dead corners or subsequent repainting work, thereby ensuring the spraying efficiency and spraying effect of the door and window body 4.

[0061] Example 8: Reference Figure 1 , Figure 2 , Figure 4 and Figure 5, a surface spraying device for rust prevention of metal doors and windows. On the basis of Example 7, further, the first positioning component includes a plurality of threaded rods 17 threadedly connected to the first support 2, each threaded rod 17 is provided with a knob 171, and a positioning plate 172 is provided at the end of the threaded rod 17 away from the knob 171. The positioning plate 172 and the L-shaped plate 1005 are both provided with a plurality of evenly distributed second balls 19. The top of the first support 2 is connected to the second support 18 through a connecting rod 201, and the second support 18 is provided with a second positioning component with the same structure as the first positioning component.

[0062] Specifically, the door and window body 4 is placed in the second support 18 and the first support 2 in sequence, and the bottom of the door and window body 4 is supported by the L-shaped plate 1005. When the first positioning assembly and the second positioning assembly are working, the knob 171 is turned to drive the threaded rod 17 to rotate, and the threaded rod 17 moves relative to the support, so that the positioning plate 172 at the end of the threaded rod 17 abuts against the side of the door and window body 4, and the positioning plate 172 contacts the side of the door and window body 4 through the second ball 19, so that when the subsequent pushing assembly pushes the door and window body 4 upward, the positioning plate 172 is lowered. 172 As for the resistance to movement of the door and window body 4, it should be noted that, by arranging the second support 18 on the upper side of the first support 2, it is also for the purpose of providing auxiliary support for the upper part of the door and window body 4 which is moved upward out of the first support 2, so as to ensure the stable movement of the door and window body 4 after moving out of the first support 2. The fan 9 is placed between the first support 2 and the second support 18, so that the paint layer of the door and window body 4 is dried before entering the second support 18, so as to prevent the undried paint layer from being abutted by the second positioning component of the second support 18 and being subjected to force, resulting in uneven distribution of the paint layer.

[0063] Working principle: the door and window body 4 is sequentially placed in the second support 18 and the first support 2, the bottom of the door and window body 4 is supported by the L-shaped plate 1005, the first positioning assembly and the second positioning assembly work, by turning the knob 171, the knob 171 drives the threaded rod 17 to rotate, the threaded rod 17 moves relative to the support, and then the positioning plate 172 at the end of the threaded rod 17 abuts against the side of the door and window body 4, and the positioning plate 172 contacts the side of the door and window body 4 through the second ball 19;

[0064] Then, the rotating assembly is controlled to operate, and the output shaft of the driving motor 5 drives the driving shaft 501 to rotate, and the driving shaft 501 drives the connecting rod 503 to rotate through the telescopic plate 502, and the sliding rod 504 at the bottom of the connecting rod 503 slides in the track groove 301, and the telescopic plate 502 is freely extended and retracted during this period, so that the paint spraying assembly outside the connecting rod 503 moves upward around the door and window body 4, and the paint spraying gun head 604 works and extracts the paint from the paint spraying material box 602 through the guide pipe 603, and then sprays the door and window body 4 while moving with the sleeve 6 and the connecting rod 503;

[0065] When the driving shaft 501 drives the connecting rod 503 to rotate by using the telescopic plate 502, the driven gear 5041 on the lower side of the sliding rod 504 moves with the connecting rod 503, and the driven gear 5041 is meshed with the rack 3011 in the groove of the track groove 301 for transmission. The driven gear 5041 drives the connecting rod 503 to rotate through the sliding rod 504. When the connecting rod 503 rotates, the first missing gear 5031 on the outer side is meshed with the first sub-gear 8 on the first winding rod 801 for transmission. The first winding rod 801 winds up the first pull rope 802. When the first missing gear 5031 is no longer meshed with the first sub-gear 8, the first winding rod 801 returns to its original position and rotates. , the first pull rope 802 is released, so that the first pull rope 802 reciprocates and pulls one end of the paint spray gun head 604, so that the paint spray gun head 604 rotates on the connecting plate 703 with the pin as the center, so that the paint spray gun head 604 can swing back and forth up and down when moving along the side of the door and window body 4, which is convenient for spraying the top wall and the bottom wall of the door and window body 4, and avoids the paint spray gun head 604 spraying the door and window body 4 in a single direction, and cannot effectively spray the top or bottom of the door and window body 4, so that the door and window body 4 can be sprayed in all directions at a single time, without the need to disassemble the door and window body 4 for repainting, thereby ensuring the efficiency of the painting work of the door and window body 4;

[0066] When the rotating assembly is working, the driving shaft 501 drives the transmission rod 14 to rotate through the first synchronous wheel 15 and the first synchronous belt, and the transmission rod 14 drives the screw 10 to rotate through the second synchronous wheel 16 and the second synchronous belt. When the screw 10 rotates, the sleeve 1001 connected to the outer thread moves up, and the sleeve 1001 drives the slide 1003 and the slide 1004 to move up through the connecting plate 703, and the door and window body 4 supported on the L-shaped plate 1005 is lifted. During this period, the screw 10 drives the rotating rod 11 to rotate through the guide bar 12, and the second missing gear 112 on the rotating rod 11 is connected to the second winding The second sub-gear 13 on the rod 131 is intermittently meshed, so that when one of the second winding rods 131 on both sides of the slide 1003 winds up the second pull rope 132 connected thereto, the other second winding rod 131 releases the second pull rope 132 connected thereto, so that the slide 1004 drives the L-shaped plate 1005 to move back and forth left and right relative to the slide 1003, so that the L-shaped plate 1005 will not always block a certain position at the bottom of the door and window body 4, so that the paint spray gun head 604 can spray the bottom support position of the door and window body 4, avoiding the occurrence of spraying dead angles or subsequent repainting work;

[0067] When the connecting rod 503 rotates, the outer active bevel gear 5032 meshes with the driven bevel gear 901 on the input shaft of the fan 9, so that the fan 9 runs and the hot air generated by the internal electric heating element is directed to the painted door and window body 4 for drying, so that the paint layer dries quickly, thereby improving the overall processing progress of the door and window body 4, allowing the door and window body 4 to quickly enter the next processing procedure or be put into use, thereby improving the processing efficiency of metal doors and windows.
