Description

Technical Field

[0001] The present invention relates to the technical field of civil air defense door processing, and more particularly to an automatic flipping spraying device for civil air defense door processing. Background Art

[0002] In the construction of civil air defense projects (civil air defense works), civil air defense doors are key protective facilities, and their manufacturing quality directly affects the protective performance and durability of the projects. Civil air defense doors are usually made of heavy metal materials (such as steel structures), and their surfaces need to be treated with anti-corrosion and rust-proof spraying to ensure their long-term stability in humid, airtight or harsh environments.

[0003] During the processing of civil air defense doors, it is necessary to spray the entire surface of the doors. Therefore, when the spraying device is performing spraying work, it is necessary to flip the civil air defense doors to facilitate double-sided spraying. The existing spraying device realizes the flipping of civil air defense doors in the following way: by clamping one side of the civil air defense door panel through a clamping mechanism, with one side of the civil air defense door panel facing the spraying mechanism; when flipping is required, the clamping mechanism is driven to rotate around the connection with the frame body to drive the civil air defense door panel to flip. However, this flipping method changes the position of the civil air defense door panel, affecting subsequent spraying operations. Moreover, since the surface of the civil air defense door panel faces the spraying mechanism, when the civil air defense door panel flips, it is necessary to change the position of the spraying mechanism, otherwise interference is likely to occur, increasing the operation complexity and the space occupied by flipping.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The left, right, up, and down positions of the various components given in the drawings are only one arrangement method, and the specific positions are set according to specific needs.

[0030] In one embodiment, Figures 1 - 3As shown in the figure, an automatic flipping spraying device for processing civil air defense doors includes a main frame body 100, a door panel installation mechanism 300 and a spraying component 400. The main frame body 100 is composed of flipping support frames 110 arranged oppositely and a spraying frame body 120. The spraying component 400 is arranged on the spraying frame body 120 and can slide vertically on the spraying frame body 120. The door panel installation mechanism 300 is arranged on the flipping support frame 110, and the door panel installation mechanism 300 includes a door body installation frame 310 for installing the civil air defense door panel 200, a falling prevention and clamping component 360, two follower connecting rods 320 and two fulcrum shafts 330. The flipping support frame 110 has two supports. The door body installation frame 310 is arranged between the two supports. The two fulcrum shafts 330 and the two follower connecting rods 320 correspond one by one and are respectively located on both sides of the door body installation frame 310. The fulcrum shaft 330 is connected to the end of the side frame of the door body installation frame 310 through an active connecting rod 350. One of the fulcrum shafts 330 is connected to a flipping motor 340. One end of the follower connecting rod 320 is hinged to the middle position of the side frame of the door body installation frame 310 and the other end is hinged to the support on the same side. One end of the door body installation frame 310 has a front card slot part 370 for clamping one end of the civil air defense door panel 200. The falling prevention and clamping component 360 is arranged at the other end of the door body installation frame 310. The falling prevention and clamping component 360 can clamp the other end of the civil air defense door panel 200 located in the door body installation frame 310 and make it in the central position of the door body installation frame 310.

[0031] In an embodiment of the present invention, the flipping motor 340 operates and drives one of the fulcrum shafts 330 to rotate. The fulcrum shaft 330 acts on one end of the door body mounting frame 310 through the active connecting rod 350. Since the active connecting rod 350 rotates around the center of the fulcrum shaft 330 and the end of the follower connecting rod 320 is connected to the support, the door body mounting frame 310 moves towards the side of the flipping support frame 110 away from the spraying frame body 120. Due to the hinge restriction at the middle position of the side frame of the door body mounting frame 310 by the follower connecting rod 320, the active connecting rod 350 acting on the door body mounting frame 310 also drives the door body mounting frame 310 to rotate around the hinge point with the end of the follower connecting rod 320. Thus, the door body mounting frame 310 can achieve a 180-degree flip. The door body mounting frame 310 is supported by the follower connecting rod 320 and the active connecting rod 350, and the support points are located at different positions, improving the connection stability of the door body mounting frame 310. In the initial state, the door body mounting frame 310 rotates vertically and its front face faces the spraying frame body 120. After the door body mounting frame 310 flips 180 degrees, the back face of the door body mounting frame 310 will face the spraying frame body 120. There is a horizontal state during the 180-degree flip of the door body mounting frame 310. When the door body mounting frame 310 is in the horizontal state and the anti-falling clamping component 360 is located at the end of the door body mounting frame 310 away from the spraying frame body 120, the civil air defense door panel 200 can be placed on the door body mounting frame 310 through a feeding mechanism such as a conveyor belt or a manipulator. The front end of the civil air defense door panel 200 is stuck in the front end card slot part 370 and the tail is clamped by the anti-falling clamping component 360, facilitating the feeding and installation of the civil air defense door panel 200. When the civil air defense door panel 200 is placed on the door body mounting frame 310, the anti-falling clamping component 360 also acts on both sides of the civil air defense door panel 200 and makes it in the middle position of the door body mounting frame 310, realizing automatic centering, facilitating the subsequent spraying component 400 to accurately spray the paint, and at the same time adapting to civil air defense door panels 200 of different widths and ensuring the installation firmness of the civil air defense door panel 200. After the civil air defense door panel 200 is installed on the door body mounting frame 310, the door body mounting frame 310 flips under the action of the flipping motor 340, the follower connecting rod 320 and the fulcrum shaft 330 to drive the 180-degree flip of the civil air defense door panel 200. Thus, both end faces of the civil air defense door panel 200 can face the spraying component 400. When the spraying component 400 reciprocates vertically along the spraying frame body 120 and works, the spraying component 400 can spray the surface of the civil air defense door panel 200, and then cooperate with the 180-degree automatic flip of the civil air defense door panel 200 to realize double-sided spraying operation. The flipping operation of the door body mounting frame 310 and the civil air defense door panel 200 is carried out in the area on the side of the main frame body 100 away from the spraying frame body 120, without interfering with the spraying frame body 120 and the spraying component 400, and effectively reducing the size and floor area of the entire spraying device.

[0032] In one embodiment, as Figures 1 - 5As shown, the anti-falling clamping assembly 360 includes an anti-falling blocking rod 361, a clamping cylinder part 366, and two pressing and centering units. The anti-falling blocking rod 361 is located at the end of the door mounting frame 310 away from the front card slot part 370, and anti-falling sleeve bodies 362 are respectively arranged at both ends of the anti-falling blocking rod 361. The two anti-falling sleeve bodies 362 are respectively sleeved on the two side frames of the door mounting frame 310. The two pressing and centering units are symmetrically and slidably arranged on the anti-falling blocking rod 361 and can slide on the anti-falling blocking rod 361. One end of the pressing and centering unit extends to the inner side of the door mounting frame 310. The clamping cylinder part 366 is arranged on the side of the anti-falling blocking rod 361, and the two telescopic ends of the clamping cylinder part 366 are respectively connected to the two pressing and centering units. In the embodiment of the present invention, when the door mounting frame 310 is flipped to the horizontal state and the anti-falling clamping assembly 360 is located at the end of the door mounting frame 310 away from the spraying frame body 120, the front card slot part 370 is located on the upper end surface of the door mounting frame 310. The civil air defense door panel 200 is placed on the door mounting frame 310 by a conveyor belt or a manipulator. One end of the civil air defense door panel 200 is inserted into the front card slot part 370, and the other end is placed on the anti-falling blocking rod 361. Since the anti-falling sleeve body 362 can slide on the frame of the door mounting frame 310 and is fastened by bolts, the position of the anti-falling blocking rod 361 on the door mounting frame 310 can be adjusted to adapt to the length of the civil air defense door panel 200. The end of the pressing and centering unit extending to the inner side of the door mounting frame 310 can act on the side part of the civil air defense door panel 200 and move it towards the center position of the door mounting frame 310 to achieve automatic centering and automatic precise positioning before spraying operation. The clamping cylinder part 366 works and acts on the two pressing and centering units at the same time. The two pressing and centering units move synchronously towards the middle position on the anti-falling blocking rod 361. The pressing and centering units can clamp the corners of the civil air defense door panel 200 to limit the movement of the civil air defense door panel 200 on the door mounting frame 310 and the anti-falling blocking rod 361, and ensure the stability during flipping and spraying.

[0033] In one embodiment, as Figures 1 - 5As shown, the pressing and centering unit includes a corner clamping part 363, a centering rod 364, and a centering top roller 365; the corner clamping part 363 is sleeved on the anti-falling stop rod 361 and the corner clamping part 363 is connected to the telescopic end of the clamping cylinder part 366, and the corner clamping part 363 is used to clamp the corner position of the civil air defense door panel 200; one end of the centering rod 364 is rotatably connected to the bottom of the corner clamping part 363 through a spring bearing, and the other end of the centering rod 364 extends towards the center position inside the door body installation frame 310 in an inclined manner, and the centering top roller 365 is rotatably arranged at the end of the centering rod 364 away from the corner clamping part 363; in the embodiment of the present invention, in the initial state, the centering rods 364 in the two pressing and centering units point to the center of the door body installation frame 310 due to the elastic force of the spring bearing; when the civil air defense door panel 200 is placed on the door body installation frame 310, the centering top roller 365 abuts against the side edge of the civil air defense door panel 200, and due to the elastic force of the spring bearing, the two centering top rollers 365 always apply a pushing force to the side edge of the civil air defense door panel 200; when the civil air defense door panel 200 is not in the middle position of the door body installation frame 310, the pushing forces applied by the two centering top rollers 365 to the civil air defense door panel 200 are different, so the civil air defense door panel 200 moves sideways and moves to the middle position of the door body installation frame 310. At this time, the pushing forces applied by the centering top rollers 365 to the side edge of the civil air defense door panel 200 are the same; the corner clamping part 363 clamps the corners of the civil air defense door panel 200 under the action of the clamping cylinder part 366 to limit the movement of the civil air defense door panel 200.

[0034] In one embodiment, as Figures 1 - 3 Figure 6As shown, the corner clamping part 363 includes a movable seat 3631, an upper clamping plate 3632, a fall-blocking rod 3633 and a follower connection part 3634; the movable seat 3631 is slidably sleeved on the anti-fall blocking rod 361 and is connected to the telescopic end of the clamping cylinder part 366; a fall-blocking adapter column 3636 is provided on the top of the movable seat 3631, one end of the fall-blocking rod 3633 is rotatably connected to the fall-blocking adapter column 3636 and is provided with a driven rod frame 3638; the upper clamping plate 3632 is provided on the side of the movable seat 3631 and is fixedly connected thereto, and a V-shaped gap is formed between the upper clamping plate 3632 and the anti-fall blocking rod 361 shaped clamping groove; the follower connection part 3634 can be slidably arranged at the end where the upper clamping plate 3632 and the movable seat 3631 are connected, one end of the follower connection part 3634 extends to the V-shaped clamping groove, and the other end is connected to the end of the upper clamping plate 3632 through a follower spring part 3635, and the follower connection part 3634 is also provided with a toggle column 3637 extending into the driven rod frame 3638; in the embodiment of the present invention, when the civil defense door panel 200 is on the door body mounting frame 310 and the end of the civil defense door panel 200 away from the front end slot part 370 is placed on the anti-fall blocking rod 361, the clamping cylinder part 366 acts on the movable seat 3631 approaches the air defense door panel 200, and the corners of the air defense door panel 200 are gradually placed in the V-shaped groove, which can clamp the corners of the air defense door panel 200 from the side; when the side of the air defense door panel 200 is placed in the V-shaped groove, it can act on the end of the follower connection part 3634 extending into the V-shaped groove to push the follower connection part 3634, and the follower connection part 3634 acts on the driven rod frame 3638 through the toggle column 3637, and the driven rod frame 3638 drives the anti-fall rod 3633 to rotate around the anti-fall adapter column 3636 through the anti-fall adapter column 3636, so that the anti-fall rod 3633 is connected to the anti-fall blocking rod 3636. 61 rotates from a parallel state to a crossed state, so that the anti-fall rod 3633 rotates to the end of the civil defense door panel 200 and the two are tightly pressed against each other; when the civil defense door panel 200 flips over and the anti-fall clamping assembly 360 is located below the door body mounting frame 310, the anti-fall rod 3633 can prevent the civil defense door panel 200 from moving downward due to its own gravity to overcome the clamping damping of the upper clamping plate 3632, so as to ensure the installation firmness of the civil defense door panel 200; during disassembly and installation, it is only necessary to control the extension and contraction of the clamping cylinder part 366 to realize the clamping restriction and release of the civil defense door panel 200 by the centering unit, which is convenient for loading and unloading.

[0035] In one embodiment, Figures 1 - 6As shown, a vertical induction part 130 is arranged between two supports of the flipping support frame 110, and the vertical induction part 130 is located below the door installation frame 310. The vertical induction part 130 is electrically connected to the flipping motor 340. A top pressing convex part 367 at the middle position is arranged on both the anti-falling blocking rod member 361 and the end of the door installation frame 310 away from the anti-falling clamping assembly 360. When the door installation frame 310 is in the vertical state, the top pressing convex part 367 abuts against the vertical induction part 130. In the embodiment of the present invention, when realizing the flipping of the civil air defense door panel 200, when the door installation frame 310 is in the vertical state, the top pressing convex part 367 abuts against the vertical induction part 130, and the vertical induction part 130 is pressed and generates an induction signal, so that it can be confirmed that the civil air defense door panel 200 is in the vertical state and opposite to the spraying component 400. At this time, the vertical induction part 130 can transmit the induction signal to the flipping motor 340, and the flipping motor 340 stops working and uses its own braking mechanism to restrict the rotation of the fulcrum shaft 330. Furthermore, through the follow-up action connecting rod 320 and the active connecting rod 350, the movement of the door installation frame 310 can be effectively restricted, ensuring that after each flipping, the civil air defense door panel 200 is kept in a relatively stable state relative to the spraying component 400.

[0036] In one embodiment, as Figures 1 - 6 shown, a horizontal induction part 140 is further arranged on the flipping support frame 110, and the horizontal induction part 140 is electrically connected to the flipping motor 340. When the active connecting rod 350 rotates around the fulcrum shaft 330 and passes through the horizontal induction part 140, the active connecting rod 350 can come into contact with the horizontal induction part 140. At this time, the door installation frame 310 is in the horizontal state. In the embodiment of the present invention, when adjusting the state of the door installation frame 310, the active connecting rod 350 acts on the horizontal induction part 140, the horizontal induction part 140 is pressed and generates an induction signal, and the flipping motor 340 can stop working to ensure that the door installation frame 310 is in the horizontal state, which is convenient for loading and unloading.

[0037] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, a vertical lead screw 600 rotatably engaged with the spraying frame 120 is provided on the spraying frame 120, and a spraying motor 610 is connected to the top of the vertical lead screw 600; the spraying component 400 includes a paint tank 410 and a spraying module. Lifting sleeves 470 are provided at both ends of the spraying module. The lifting sleeves 470 are vertically slidably engaged with the spraying frame 120, and the vertical lead screw 600 spirally penetrates through one of the lifting sleeves 470; the paint tank 410 is arranged at the bottom of the spraying frame 120 and is connected to the spraying module through a flexible feeding pipe 460; in the embodiment of the present invention, the paint in the paint tank 410 is introduced into the spraying module through the flexible feeding pipe 460 and is sprayed by the spraying module onto the surface of the civil air defense door panel 200 opposite thereto; when the spraying motor 610 works and drives the vertical lead screw 600 to rotate, the rotating vertical lead screw 600 can make the spraying module reciprocally move vertically on the spraying frame 120 through the spiral engagement with one of the lifting sleeves 470, so that the spraying module can comprehensively spray the civil air defense door panel 200.

[0038] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 7 shown, the spraying module includes a spraying plate 420, a material guiding pipe 440 and a plurality of spray heads 430. The two ends of the spraying plate 420 are respectively connected to the two lifting sleeves 470. The plurality of spray heads 430 are arranged side by side on the spraying plate 420.

[0041] In the above-described embodiment of the invention, an automatic flipping type spraying device for processing civil air defense doors is provided. Among them, the flipping motor 340 operates and drives one of the pivot shafts 330 to rotate. The pivot shaft 330 acts on one end of the door body mounting frame 310 through the active connecting rod 350. Due to the rotation of the active connecting rod 350 around the center of the pivot shaft 330 and the connection of the end of the follower connecting rod 320 to the support, the door body mounting frame 310 moves towards the side of the flipping support frame 110 away from the spraying frame body 120. Due to the hinge restriction at the middle position of the side frame of the door body mounting frame 310 by the follower connecting rod 320, the active connecting rod 350 acting on the door body mounting frame 310 also drives the door body mounting frame 310 to rotate around its hinge point with the end of the follower connecting rod 320, so that the door body mounting frame 310 can achieve a 180-degree flip; in the initial state, the door body mounting frame 310 is in a vertical rotation and its front end face faces the spraying frame body 120. After the door body mounting frame 310 flips 180 degrees, the back face of the door body mounting frame 310 will face the spraying frame body 120; there is a horizontal state during the 180-degree flip of the door body mounting frame 310; when the door body mounting frame 310 is in a horizontal state and the anti-falling clamping component 360 is located at the end of the door body mounting frame 310 away from the spraying frame body 120, the civil air defense door panel 200 can be placed on the door body mounting frame 310 through a feeding mechanism such as a conveyor belt or a manipulator. The front end of the civil air defense door panel 200 is stuck in the front slot part 370 and the tail is clamped by the anti-falling clamping component 360, which is convenient for loading and installing the civil air defense door panel 200; when the civil air defense door panel 200 is placed on the door body mounting frame 310, the anti-falling clamping component 360 also acts on both sides of the civil air defense door panel 200 and makes it in the middle position of the door body mounting frame 310, realizing automatic centering, which is convenient for the subsequent spraying component 400 to accurately spray the paint, and also adapts to civil air defense door panels 200 of different widths and ensures the installation firmness of the civil air defense door panel 200; after the civil air defense door panel 200 is installed on the door body mounting frame 310, the door body mounting frame 310 flips under the action of the flipping motor 340, the follower connecting rod 320 and the pivot shaft 330 to drive the 180-degree flip of the civil air defense door panel 200, so that both end faces of the civil air defense door panel 200 can face the spraying component 400; when the spraying component 400 reciprocates vertically along the spraying frame body 120 and works, the spraying component 400 can spray the surface of the civil air defense door panel 200, and cooperate with the 180-degree automatic flip of the civil air defense door panel 200 to realize double-sided spraying operation; the door body mounting frame 310 and the civil air defense door panel 200 perform flipping operations in the area on the side of the main frame body 100 away from the spraying frame body 120, will not interfere with the spraying frame body 120 and the spraying component 400, and effectively reduce the size of the entire spraying device and the occupied space.
