[0002] Alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and leaf materials. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material of load-bearing rods and doors and windows composited with wood and plastic, or aluminum-wood composite doors and windows or aluminum-plastic composite doors and windows for short.

[0003] The patent with announcement number CN112371388A discloses an anti-rust spraying device for the surface of aluminum alloy door and window profiles after processing, including a supporting mechanism for supporting the device, a paint spraying mechanism for spraying paint, and a lifting mechanism for lifting the paint spraying mechanism. The paint spraying mechanism is arranged in the supporting mechanism, and the lifting mechanism is arranged on the upper side of the paint spraying mechanism. The lifting mechanism is slidably connected with the paint spraying mechanism, the lifting mechanism is connected with the supporting mechanism by screws, and the paint spraying mechanism is connected with the supporting mechanism by screws. When in use, the device clamps and fixes the aluminum alloy doors and windows, and then sprays them. This will make the surface of the clamped part unable to be sprayed with paint, and generally only one side can be sprayed. It is necessary to wait for the sprayed part to dry before turning it over and spraying it again. Due to the large area, it is time-consuming to re-spray afterwards.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example

[0020] like Figure 1 and Figure 2As shown, the present embodiment discloses an anti-rust spraying device for the production and processing of aluminum alloy doors and windows, comprising two sets of frames 1 fixedly installed perpendicularly to each other, wherein a conveying device 2 for conveying aluminum alloy door and window frames to be sprayed is fixedly installed on the upper end of one of the frames 1, and two gantries 7 are fixedly installed on the upper end of the other frame 1, and a conveying device 2 8 is fixedly installed below the horizontal parts of the two gantries 7, and a stepper motor 9 for driving the conveying device 2 8 to work is also fixedly installed on the top of the gantries 7, and a stepper motor 2 10 for driving the conveying device 2 to work is provided below the conveying device 2, and the stepper motor 2 10 is fixedly installed on the upper end of the frame 1, and a spray drying device 5 for spraying and drying and a spray drying device 5 for auxiliary rotation are provided in the middle of the conveying device 2 Two symmetrical auxiliary transfer components 6 are moved to the aluminum alloy door and window frames to be sprayed, and a spray drying device 11 for re-spraying and drying is fixedly installed in the middle of the conveying device 8, and the spray drying device 11 has the same overall structure as the spray drying device 5. The conveying device 8 is perpendicular to the conveying device 2 and the side of the conveying device 8 close to the conveying device 2 is suspended above the conveying device 2 and the auxiliary transfer component 6; it should be noted that in practice, the stepper motor 10 can drive the conveying device 2 to work by belt or sprocket transmission, and the stepper motor 9 can also drive the conveying device 8 to work by belt or sprocket transmission, which are conventional designs in the prior art, and their specific structures will not be repeated in this embodiment.

[0021] Among them, Figure 3 As shown, the conveying device 2 in this embodiment includes a conveying chain 22 driven by a stepper motor 10. In practice, the conveying chain 22 adopts a plate transmission chain to ensure stability during operation. Mounting side frames 21 are also provided on both sides of the conveying chain 22. The mounting side frames 21 are fixedly installed on the upper end of the frame 1 to support the conveying device 2. The outer surface of the conveying device 2 is provided with a plurality of groups of automatic clamping parts 1 for clamping the aluminum alloy door and window frames to be sprayed. The overall structure of the conveying device 2 8 is the same as the overall structure of the conveying device 2, and the conveying device 2 8 is provided with a plurality of groups of automatic clamping parts 2 for clamping the aluminum alloy door and window frames to be sprayed.

[0022] Further, such as Figure 4 As shown, each set of automatic clamping parts 1 includes two symmetrically arranged clamps 1 3, and the clamps 1 3 are composed of a lifting support 31 fixed to the surface of the conveying chain 22 and a self-locking component 1 32 fixed to the end of the lifting support 31 away from the conveying chain 22; Among them, Figure 5 and Figure 6As shown, the self-locking component 1 32 includes a base plate 321, and two vertical rails 1 322 and two vertical rails 2 326 are symmetrically fixedly installed on both sides of one end of the base plate 321 away from the lifting support member 31, and a slide plate 1 323 is slidably installed in each vertical rail 1 322, and a slide plate 2 327 is slidably installed in each vertical rail 2 326. In practice, the slide plate 1 323 and the slide plate 2 327 are kept parallel to each other, and the ends of the slide plates 2 327 and the slide plate 1 323 on the same side that are close to each other are fixed with racks 330, and a gear 331 meshing with the two racks 330 on the same side is provided between the two racks 330, so that the slide plate 2 327 and the slide plate 1 323 can always move in opposite directions through the cooperation of the rack 330 and the gear 331; In addition, an axle rod 332 is fixedly installed between the two gears 331, two bases 335 are symmetrically fixedly installed on one end of the base plate 321 away from the lifting support member 31, and the axle rod 332 is rotatably installed between the two bases 335. A horizontal plate 324 is fixedly installed on the upper part of the side of the two slide plates 1 323 away from the slide plate 2 327, and a lifting platform 325 is fixedly installed on the upper end of the horizontal plate 324. A vertical plate 328 is also fixedly installed on the upper end of the base plate 321, and two limiting rods 336 are slidably installed on the upper part of the vertical plate 328. A roller 337 is rotatably installed between the two limiting rods 336 on one side close to the lifting platform 325, and a clamping plate 329 is fixedly installed on the side of the two limiting rods 336 away from the roller 337. A bearing plate 320 is fixedly installed on one end of the two slide plates 2 327 away from the slide plate 1 323. Furthermore, the upper end surface of the lifting platform 325 is set as an inclined surface inclined toward the side of the vertical plate 328, and the inclined surface is in close contact with the outer surface of the roller 337. Two telescopic sleeves 333 and two buffer springs 334 are symmetrically fixedly installed at the lower end of the lifting platform 325, and the two buffer springs 334 are respectively mounted on the outside of the two telescopic sleeves 333.

[0023] It should be noted that in actual use, the two clamps 3 are symmetrically arranged. Therefore, when the aluminum alloy door and window frame to be sprayed is placed on the upper end of the bearing plate 320 in the two clamps 3, due to the gravity of the aluminum alloy door and window frame itself, it will exert downward pressure on the bearing plate 320, thereby driving the slide plate 2 327 to move downward in the vertical rail 2 326, and then the slide plate 1 323 is moved upward through the gear 331, and the lifting platform 325 is raised through the horizontal plate 324. Since the inclined surface at the upper end of the lifting platform 325 is in contact with the surface of the roller 337, it will push the roller 337 toward the support. Move to one side of the bearing plate 320, and use two limit rods 336 to push the clamp 329 to move to one side of the aluminum alloy door and window frame, so that the clamps 329 in the two clamps 3 can be used to clamp the two opposite sides of the aluminum alloy door and window frame to achieve automatic clamping and fixation of the aluminum alloy door and window frame. When the aluminum alloy door and window frame is removed from the bearing plate 320, the pressure applied by the aluminum alloy door and window frame to the bearing plate 320 becomes smaller. Under the pulling force provided by the buffer spring 334, the lifting platform 325 descends. At this time, the clamp 329 no longer clamps the aluminum alloy door and window frame, so that the aluminum alloy door and window frame can be taken out.

[0024] Of course, in practice, in order to protect the outer surface of the aluminum alloy door and window frame and avoid scratching the aluminum alloy door and window frame, a soft material can be provided on the surface of the bearing plate 320 and the surface of the clamping plate 329 for covering.

[0025] After the aluminum alloy door and window frame is clamped by the two clamps 3 in the automatic clamping part 1, the aluminum alloy door and window frame can be sent to the spraying and drying device 5 through the conveying chain 22, and the two sides that are not supported and clamped by the two clamps 3 are sprayed and dried for the first time, and then the aluminum alloy door and window frame is transferred to the automatic clamping part 2 through the auxiliary transfer components 6 arranged symmetrically. Therefore, if Fig. 9 As shown, the auxiliary transfer assembly 6 in this embodiment includes two inclined rails 62 parallel to each other, a limiting groove 66 is provided between the two inclined rails 62, a horizontal rail 1 61 is fixed to the same end of the two inclined rails 62, a horizontal rail 2 63 is fixedly installed to the other end of the two inclined rails 62, a flared plate 64 is fixed to the end of the two horizontal rails 1 61 away from the inclined rail 62, and the two flared plates 64 form a gradually increasing opening, and the conveying device 2 8 is suspended directly above the inclined rails 62, and the outer sides of the two horizontal rails 1 61 and the two horizontal rails 2 63 are fixed with fixed arms 65, and the bottom of the fixed arms 65 is fixedly connected to the mounting side frame 21; in this embodiment, the two auxiliary transfer assemblies 6 are symmetrically arranged on both sides of the conveying chain 22 and are fixed to the mounting side frame 21 through the fixed arms 65, and the lifting support 31 cooperates with the auxiliary transfer assembly 6 to realize the auxiliary lifting of the self-locking assembly 1 32; like Figure 7As shown, the lifting support member 31 includes a sleeve 311, a movable plate 312 is slidably installed in the inner cavity of the sleeve 311, and a coil spring 314 is provided between the movable plate 312 and the inner wall of the sleeve 311, and a support plate 313 is fixedly installed on the end of the movable plate 312 away from the coil spring 314, and the end of the support plate 313 away from the movable plate 312 passes through the sleeve 311 and extends to the outside thereof and is fixed with a top plate 317, and the top plate 317 is fixed to the lower end surface of the base plate 321, and extension arms 315 are fixedly installed on both sides of the upper part of the support plate 313, and the end of the extension arm 315 away from the support plate 313 is rotatably installed with a limiting wheel 316 used in conjunction with the auxiliary transfer assembly 6, specifically, the limiting wheel 316 is used in conjunction with the limiting groove 66 for limiting.

[0026] That is, when the clamp 1 3 moves to one side of the auxiliary transfer assembly 6 along with the conveying chain 22, the limiting wheel 316 first enters the limiting groove 66 between the two horizontal rails 1 61 through the flaring between the two flaring plates 64. At this time, the aluminum alloy door and window frame is still in a horizontal state. As the conveying chain 22 continues to move, the limiting wheel 316 moves to the limiting groove 66 corresponding to the inclined rails 62. At this time, the aluminum alloy door and window frame is in an inclined state. Finally, the limiting wheel 316 moves to the limiting groove 66 corresponding to the horizontal rail 2 63. At this time, the aluminum alloy door and window frame has been transferred from the automatic clamping part 1 to the automatic clamping part 2. Therefore, it is necessary to further explain that Figure 8 As shown, each group of automatic clamping parts 2 includes two symmetrically arranged clamps 2 4, and the clamps 2 4 include a self-locking component 2 41 and fixed plates 42 fixed on both sides of the self-locking component 2 41. The conveying device 2 8 drives the two fixed plates 42 to move the clamps 2 4 in a direction perpendicular to the conveying device 1 2, and the overall structure of the self-locking component 2 41 is the same as that of the clamp 1 3, and the overall structure of the conveying device 2 8 is the same as that of the conveying device 1 2. Therefore, the way in which the conveying device 2 8 drives the clamps 2 4 to move is also the same as the way in which the conveying device 2 drives the clamps 3 to move; It is particularly important to explain that, in the present embodiment, when the conveying device 2 8 is in the initial working state, the two self-locking components 2 41 in the automatic clamping part 2 are respectively located on both sides of the two auxiliary transfer components 6, that is, the two auxiliary transfer components 6 are located between the two self-locking components 2 41, and the positions of the two self-locking components 2 41 correspond to the positions of the inclined rail 62. At the same time, the horizontal heights of the two self-locking components 2 41 are lower than the horizontal heights of the horizontal rail 1 61. Therefore, in the process of the aluminum alloy door and window frame moving from the horizontal rail 1 61 to the horizontal rail 2 63, the other two self-locking components 2 41 are used to lock the aluminum alloy door and window frame in the same way as the clamp 1 3. The two sides supported and clamped by the two self-locking components 241 are the two sides that have been sprayed and dried, and at this time, the two clamps 3 automatically detach from the two sides that have not been sprayed and clamped at the beginning, and the two clamps 3 sink to the bottom of the aluminum alloy door and window frame, and the aluminum alloy door and window frame will not interfere with the movement of the clamps 3, so as to facilitate the subsequent spraying and drying of the two unsprayed sides. When the aluminum alloy door and window frame moves to the side of the conveying device 28 away from the conveying device 2, the spraying work of the entire aluminum alloy door and window frame is automatically completed, and the staff only needs to remove the sprayed aluminum alloy door and window frame. Example

[0027] Based on the first embodiment, the present embodiment optimizes the structures of the spray drying device 1 5 and the spray drying device 2 11 to achieve spraying and drying of aluminum alloy door and window frames; For details, please refer to Fig.10 The spray drying device 5 includes a box body 51, a box cover is provided on the top of the box body 51, a partition 52 is provided in the middle of the inner cavity of the box body 51, a vertical slot 53 for allowing the fixture 3 to pass through and a through slot 55 perpendicular to the vertical slot 53 and connected to the vertical slot 53 are provided in the middle of the partition 52, a horizontal slot 54 is also provided at the bottom of the box body 51, two groups of drying components 56 and two groups of spray components 57 are symmetrically fixed in the inner cavity of the box body 51, and the drying component 56 is located on the side close to the conveying device 28, the partition 52 is located between the drying component 56 and the spray component 57, and both sides of the box body 51 are fixed with a mounting base 58 for mounting the spray drying device 5, and the bottom of the mounting base 58 is fixedly connected to the two mounting side frames 21.

[0028] It should be noted that the purpose of providing the through groove 55 is to allow the aluminum alloy door and window frames to pass through, the purpose of providing the vertical groove 53 and the horizontal groove 54 is to allow the clamp 3 to pass freely, and the purpose of providing the partition 52 is to prevent the airflow generated by the hot air blown out by the drying component 56 from affecting the spraying process of the spraying component 57 and causing the spraying quality to fail to meet the requirements.

[0029] Specifically, Fig.11As shown, the drying component 56 includes two horizontal tubes 563, and the two horizontal tubes 563 are respectively fixed on the upper and lower inner walls of the box body 51. The two horizontal tubes 563 are fixedly installed with branch pipes 562 at one end close to the side wall of the box body 51. The two branch pipes 562 penetrate the box body 51 and extend to the outside thereof and are jointly fixed with an air inlet pipe 561. The two horizontal tubes 563 are evenly spaced at one end away from the branch pipes 562, and the air outlet nozzles 564 are all inclined inwardly.

[0030] Among them, one end of the air inlet pipe 561 away from the branch pipe 562 is connected to the output end of a hot air blower, which can continuously transport hot air into the box body 51 to achieve the purpose of quickly drying the sprayed paint, and because the air outlet nozzle 564 is inclined inward, the hot air can directly contact the surface of the paint after spraying, and the evaporation rate of water in the paint is increased by accelerating the air flow, thereby improving the drying effect. After drying, the paint surface can be prevented from being damaged due to the clamping of the clamp 2 4 and the two frame supports after spraying in the subsequent spraying process, thereby improving the quality of product processing.

[0031] like Fig.12 As shown, the spray assembly 57 includes a feed pipe 571, which extends through the side wall of the box body 51 to the inside of the box body 51 and is fixedly installed with a U-shaped tube 572. A number of nozzles 573 are fixedly installed on the same side of the outer surface of the U-shaped tube 572. The end of the feed pipe 571 away from the U-shaped tube 572 is connected to the output end of the paint spraying equipment. The paint spraying equipment can be a conventional design in the prior art, and its specific structure is not described in detail in this embodiment. After the aluminum alloy door and window frame first enters the box body 51, multiple nozzles 573 are used to spray the frame that is not supported and clamped by the two clamps 3.

[0032] In addition, in order to improve the spraying quality and ensure that the paint can be sprayed in every corner gap of the aluminum alloy door and window frame, the number and installation arrangement of the nozzles 573 in this embodiment can be set as follows: Fig.13 In the state shown, the two nozzles 573 in the middle spray the upper and lower surfaces of the aluminum alloy door and window frame respectively, and the nozzle 573 close to the feed pipe 571 sprays the outer side of the aluminum alloy door and window frame, and the two nozzles 573 far from the feed pipe 571 are both inclined inwardly, and are used to spray the inner side of the aluminum alloy door and window frame to improve the quality of spraying.

[0033] It should be noted that the structure of the spray drying device 11 is exactly the same as that of the spray drying device 5. The only difference is that the spray drying device 11 is installed below the conveying device 8 and used in conjunction with the clamp 4, while the spray drying device 5 is installed above the conveying device 2 and used in conjunction with the clamp 3. Example

[0034] This embodiment, based on the first and second embodiments, specifically describes the specific use method of the anti-rust spraying device for the production and processing of aluminum alloy doors and windows disclosed in the present invention, and the specific steps are as follows: S1: Preparation before spraying: Start the stepper motor 2 10, move the automatic clamping part 1 to the upper part of the side away from the auxiliary transfer assembly 6, and move the automatic clamp conveying device 1 2 to the top of the inclined rail 62 and let the two clamps 2 4 be located outside the two auxiliary transfer assemblies 6, and then place the aluminum alloy door and window frame to be sprayed between the two clamps 1 3, and automatically clamp it under the gravity of the aluminum alloy door and window frame itself; S2: Perform the first spraying and drying: Start the stepper motor 2 10, move the aluminum alloy door and window frame to be sprayed to the spraying and drying device 1 5 for spraying and drying, spray the two opposite sides of the aluminum alloy door and window frame to be sprayed, and then cooperate with the auxiliary transfer component 6 to allow the aluminum alloy door and window frame to be sprayed to enter the automatic clamping part 2 and be clamped by the two clamps 2 4; S3: Perform the second spraying and drying: Start the stepper motor 19, and allow the aluminum alloy door and window frame to be sprayed to enter the spraying and drying device 11 through the movement of the clamp 2 4 and the conveying device 2 8. The spraying and drying device 11 sprays and dries the other two side edges of the aluminum alloy door and window frame to be sprayed. After completion, the aluminum alloy door and window frame to be sprayed can be removed.
