[0019] Compared with the related technology, a fixed-point spraying device for steel door spraying provided by the present utility model has the following beneficial effects:
[0020] The present utility model provides a fixed-point spraying device for steel door spraying. When using the spraying device to perform fixed-point spraying operations on steel door panels, the feeding rack is first slid out of the frame along the feeding track, and the steel door panel is placed on the feeding rack with reference to the marking line. The feeding rack drives the steel door panel to access the corresponding spraying device in the frame. Then, the working strokes of the moving arm and the spraying device are programmed through the operation interface, and the device is started. The spraying device and the moving arm move in cooperation to perform spraying operations on the surface of the steel door panel. However, the following problems will occur in this operation. During the process of manually turning over the steel door panel and subsequently placing the steel door panel to be processed, there is a lack of limit between the feeding rack and the steel door panel. The steel door panel is placed only relying on the marking line, and the user cannot accurately place it in the center, resulting in a position deviation, and further resulting in low quality of the sprayed product. By setting an adjustment structure, first adjust the distance between the two positioning plates according to the width of the steel door panel. Rotate the adjusting rod, and the adjusting rod drives the two positioning plates to move by means of a double-thread. The two positioning plates move along the round rod towards each other at the same time. After the distance between the two positioning plates is appropriate, move the steel door panel downwards between the two positioning plates and make the steel door panel abut against the upper surfaces of the two support frames. At this time, the steel door panel is centered in the width direction. When feeding the steel door panels of the same batch subsequently, the adjusting rod does not need to be adjusted. Then start the servo motor, and the servo motor drives the double-threaded screw to rotate. The double-threaded screw drives the two moving plates to move along the inner wall of the fixed frame by means of the thread. The two moving plates move towards each other at the same time. The moving plates drive the limiting frames to clamp the steel door panel, so that the steel door panel is centered in the length direction. The feeding rack drives the steel door panel into the frame for spraying operations. After the spraying operations are completed, the feeding rack is moved out, and the servo motor rotates in reverse, so that the two limiting frames move away from each other. Take out or turn over the steel door panel for subsequent feeding. Among them, the friction between the moving plate and the fixed frame is reduced by the pulley, so that the moving plate moves more smoothly along the fixed frame. The moving plate is further limited by the sliding rod, so that the moving plate moves more stably along the fixed frame. It is realized that when loading the steel door panel, the four sides of the steel door panel are limited by the positioning plate and the limiting frame, so that the steel door panel is placed in the center on the feeding rack, improving the spraying quality and the working efficiency of the spraying operation.
[0021] During the spraying operation, when the spraying device sprays along the edge of the steel door panel, the paint will fall on the ground and is difficult to clean. By setting up an auxiliary structure, first slide the bottom plate out along the frame body, rotate and open the two extrusion frames. During this process, the extrusion frames rotate along the arc surface of the fixed rod, and the torsion spring always gives the extrusion frames a torsional force. Then lay the protective film between the two groups of fixed blocks, release the extrusion frames, and the extrusion frames reverse under the action of the torsional force of the torsion spring. The extrusion frames press the protective film downward against the bottom plate. Then move the bottom plate directly below the loading rack. Among them, the friction on the surface of the extrusion frames is increased through the anti-slip pads, so that the limiting effect of the extrusion frames on the protective film is better. The bottom plate is driven to move by operating the handle, which is convenient for the user to move the bottom plate. It realizes installing the protective film on the bottom plate, using the protective film to catch the spilled paint, preventing the paint from polluting the ground, and the disassembly and installation operation of the protective film is simple and convenient, with high practicability.

[0032] In an embodiment of the present invention, please refer to Figure 5, the auxiliary structure 9 includes a bottom plate 91 which is slidably connected to the frame body 1. The bottom plate 91 is located directly below the loading rack 6. A protective film 98 is abutted against the upper surface of the bottom plate 91. A plurality of fixing blocks 92 are fixedly connected to the upper surface of the bottom plate 91 at positions corresponding to the protective film 98. Every two of the plurality of fixing blocks 92 form a group. A fixing rod 93 is fixedly connected to the side of the same-group fixing blocks 92 close to each other.

Two handles 97 are fixedly connected to the upper surface of the bottom plate 91. The cross section of the handle 97 is in a "U" shape. The bottom plate 91 is driven to move by operating the handle 97, which is convenient for the user to move the bottom plate 91.
[0033] The working principle of a fixed-point spraying device for steel doors provided by the utility model is as follows: By setting the adjustment structure 8, first adjust the distance between the two positioning plates 803 according to the width of the steel door panel 7. Rotate the adjustment rod 802, and the adjustment rod 802 drives the two positioning plates 803 to move by means of a double-thread. The two positioning plates 803 move along the round rod 804 towards each other at the same time. After the distance between the two positioning plates 803 is appropriate, move the steel door panel 7 from top to bottom between the two positioning plates 803, and make the steel door panel 7 abut against the upper surfaces of the two support frames 801. At this time, the steel door panel 7 is centered in the width direction. When feeding the same batch of steel door panels 7 later, the adjustment rod 802 does not need to be adjusted. Then start the servo motor 806, and the servo motor 806 drives the double-threaded screw 807 to rotate. The double-threaded screw 807 drives the two moving plates 808 to move along the inner wall of the fixed frame 805 by means of the thread. The two moving plates 808 move towards each other at the same time. The moving plate 808 drives the limiting frame 809 to clamp the steel door panel 7, so that the steel door panel 7 is centered in the length direction. The feeding frame 6 drives the steel door panel 7 into the frame body 1 for spraying operation. After the spraying operation is completed, the feeding frame 6 moves out, and the servo motor 806 rotates in reverse, so that the two limiting frames 809 move away from each other, and the steel door panel 7 is taken out or flipped for subsequent feeding. Among them, the pulley 810 reduces the friction between the moving plate 808 and the fixed frame 805, making the moving plate 808 move more smoothly along the fixed frame 805. The sliding rod 811 further limits the moving plate 808, making the moving plate 808 move more stably along the fixed frame 805. When operating the steel door panel 7 for feeding, the positioning plate 803 and the limiting frame 809 are used to limit the four sides of the steel door panel 7, so that the steel door panel 7 is centered on the feeding frame 6, improving the spraying quality and the working efficiency of the spraying operation.
[0034] By setting the auxiliary structure 9, first slide the bottom plate 91 out of the frame body 1, and rotate to open the two extrusion frames 94. During this process, the extrusion frames 94 rotate along the arc surface of the fixed rod 93, and the coil spring 95 always gives the extrusion frames 94 a torsional force. Then lay the protective film 98 between the two groups of fixed blocks 92, release the extrusion frames 94, and the extrusion frames 94 reverse under the action of the torsional force of the coil spring 95. The extrusion frames 94 press the protective film 98 downward against the bottom plate 91. Then move the bottom plate 91 directly below the feeding frame 6. Among them, the anti-slip pad 96 increases the friction on the surface of the extrusion frame 94, making the limiting effect of the extrusion frame 94 on the protective film 98 better. By operating the handle 97 to drive the bottom plate 91 to move, it is convenient for the user to move the bottom plate 91. It realizes that the protective film 98 is installed on the bottom plate 91, and the protective film 98 is used to pick up the spilled paint, preventing the paint from polluting the ground. The disassembly and assembly operation of the protective film 98 is simple and convenient, and the practicability is high.
