Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile production, and particularly relates to a spraying device for aluminum profile production. Background Art

[0002] Aluminum profiles are products made of aluminum and other alloy elements. Usually, they are first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then made through processes such as cold bending, sawing, drilling, assembling, and coloring. The main metal element is aluminum, and some alloy elements are added to improve the performance of the aluminum material. In order to improve the aesthetics and corrosion resistance of aluminum profiles, it is necessary to spray coatings on their surfaces with the help of corresponding spraying devices after the production of aluminum profiles.

[0003] A spraying powder booth for spraying aluminum profiles provided by the publication number "CN213914643U" is provided with an exhaust fan and an activated carbon plate, which can effectively prevent the polluted air from being exposed in the working environment of users, thereby avoiding air pollution. It is provided with a deflector plate and a collection bin to achieve the centralized collection of dust, which is convenient for users' subsequent recycling and utilization.

[0004] However, the above technical solutions and the existing technologies have the following defects:

[0005] Although this spraying powder booth can centrally collect dust, the nozzles in this spraying powder booth adopt a fixed structure. As a result, in the actual use process, the nozzles cannot move up and down to spray the aluminum profiles, and the aluminum profiles hung inside the spraying powder booth cannot move back and forth either. Thus, the nozzles in this spraying powder booth cannot fully spray the left and right end faces of the aluminum profiles, and the practicability is poor. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a spraying device for aluminum profile production to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A spraying device for aluminum profile production includes a spraying booth, an aluminum profile to be sprayed, and an installation cavity. An installation cavity is opened on the lower side inside the spraying booth. The aluminum profile to be sprayed is placed in front of the spraying booth. A spraying assembly is arranged inside the spraying booth, and the spraying assembly is used to spray coatings on the outer surface of the aluminum profile to be sprayed. A conveying assembly is arranged on the upper side inside the spraying booth, and the conveying assembly is used to convey the aluminum profile to be sprayed back and forth.

[0009] Preferably, the spraying assembly includes a spraying machine, a three-way connecting pipe, a servo motor, a worm, a worm gear, a reciprocating lead screw, a lifting seat, a spray gun and a delivery hose. The spraying machine is installed inside the installation cavity. The outlet of the spraying machine is connected to the three-way connecting pipe. A servo motor is installed on the upper side of the right end face of the spraying chamber. The left end of the servo motor is connected to the worm.

The circumferential side of the reciprocating lead screw is provided with a lifting seat. The right end face of the lifting seat is installed with a spray gun. A delivery hose is connected between the inlet of the spray gun and the outlet of the three-way connecting pipe.

[0010] Preferably, the conveying assembly includes a first support plate, a moving seat, an external threaded rod, a connecting vertical rod, a supporting plate, a low-speed motor and a second support plate. The first support plate is installed behind the spraying chamber. The upper side of the rear end face of the first support plate is installed with a low-speed motor. The front end of the low-speed motor is connected to the external threaded rod. The circumferential side of the external threaded rod is provided with a moving seat. The lower end face of the moving seat is fixedly connected to the connecting vertical rod. The front end face of the connecting vertical rod is fixedly connected with a plurality of supporting plates. The second support plate is installed in front of the spraying chamber.

[0011] Preferably, a limiting rod is fixedly connected between the first support plate and the second support plate. The first support plate and the second support plate are of the same height. A control panel is installed on the lower side of the front end face of the second support plate.

[0014] Preferably, the retractable distance of the delivery hose is greater than the up and down movable distance of the lifting seat. The inlet of the spraying machine is connected to the outlet of an external paint storage tank through a pipeline.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By starting the spraying machine, the spraying machine conveys paint to the spray guns on both sides through the connecting three-way pipe and the delivery hose, so that the spray guns on both sides spray out paint to simultaneously spray the left and right end faces of the aluminum profiles to be sprayed passing by. At the same time, the servo motor is started, so that the servo motor drives the reciprocating lead screws on both sides to rotate synchronously and in the same direction through the worm and the worm gears.

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A spraying device for the production of aluminum profiles, comprising a spraying chamber 1, an aluminum profile to be sprayed 4, and an installation cavity 5. An installation cavity 5 is opened on the lower side inside the spraying chamber 1, which facilitates the installation of the spraying machine 21 on the lower side inside the spraying chamber 1. The aluminum profile to be sprayed 4 is placed in front of the spraying chamber 1. A material receiving box 11 is placed on the lower side inside the spraying chamber 1. The material receiving box 11 can collect most of the paint that falls during the spraying process, avoiding the pollution of the surrounding environment by excess paint. A communication cavity 12 is opened on the left side inside the spraying chamber 1, which facilitates the axial flow fan 13 to suck most of the floating paint mist in the spraying chamber 1. An axial flow fan 13 is installed at the left end outlet of the communication cavity 12, and the outlet of the axial flow fan 13 is connected to the inlet of an external paint mist purifier through a pipeline. When the axial flow fan 13 is working, it can suck and discharge most of the floating paint mist in the spraying chamber 1, avoiding the pollution of the surrounding environment by the paint mist floating to the outside.

[0028] A spraying assembly 2 is arranged inside the spraying chamber 1, and the spraying assembly 2 is used for spraying paint on the outer surface of the aluminum profile to be sprayed 4. A conveying assembly 3 is arranged on the upper side inside the spraying chamber 1, and the conveying assembly 3 is used for conveying the aluminum profile to be sprayed 4 back and forth.

[0029] The spraying assembly 2 includes a spraying machine 21, a three-way connecting pipe 22, a servo motor 23, a worm 24, a worm gear 25, a reciprocating lead screw 26, a lifting seat 27, a spray gun 28, and a guiding hose 29. The spraying machine 21 is installed inside the installation cavity 5. The inlet of the spraying machine 21 is connected to the outlet of an external paint storage tank through a pipeline. When the spraying machine 21 is working, it can convey paint to the guiding hoses 29 on both left and right sides through the three-way connecting pipe 22. Since the internal detailed structure and working principle of the spraying machine 21 are relatively mature technologies in the prior art, no more details will be described here. The outlet of the spraying machine 21 is connected to a three-way connecting pipe 22, and the three-way connecting pipe 22 can split the conveyed paint into the guiding hoses 29 on both left and right sides. A servo motor 23 is installed on the upper side of the right end face of the spraying chamber 1. The servo motor 23 is connected to an external servo motor 23 controller through a wire. When the servo motor 23 is working, it can drive the worm 24 to rotate at the required speed.

[0030] The left end of the servo motor 23 is connected to a worm 24. The worm 24 can drive the worm wheels 25 on both the left and right sides to rotate synchronously in the same direction. The worm 24 meshes with the worm wheels 25 on both the left and right sides of its annular side. The worm wheels 25 are connected to the reciprocating lead screws 26 by welding. The worm wheels 25 can drive the reciprocating lead screws 26 to rotate. The reciprocating lead screws 26 are symmetrically arranged on both the left and right sides inside the spraying booth 1. There are two groups of reciprocating lead screws 26, and the two groups of reciprocating lead screws 26 have the same specifications. When the reciprocating lead screws 26 rotate, they can drive the lifting seats 27 to move up and down reciprocally. Since the working principle and the internal detailed structure of the reciprocating lead screws 26 are relatively mature technologies in the prior art, no further elaboration will be made here. The lifting seats 27 are arranged on the annular sides of the reciprocating lead screws 26, and the lifting seats 27 can support the spray guns 28.

[0031] The spray gun 28 is installed on the right end face of the lifting seat 27. The spray gun 28 can evenly spray the paint delivered by the delivery hose 29 outward to spray the aluminum profiles 4 to be sprayed passing by. A delivery hose 29 is connected between the inlet of the spray gun 28 and the outlet of the tee connecting pipe 22. The retractable distance of the delivery hose 29 is greater than the up and down movable distance of the lifting seat 27. The delivery hose 29 can not only deliver the paint to the spray gun 28, but also has a certain flexibility itself, so that the spray gun 28 can move up and down following the lifting seat 27. Protective baffles 271 are symmetrically arranged on the upper and lower end faces of the lifting seat 27. The protective baffles 271 are connected to the lifting seat 27 by welding. The protective baffles 271 can block most of the paint sprayed by the spray gun 28 on the opposite side, avoiding the paint being directly sprayed onto the annular side of the reciprocating lead screw 26 on the opposite side. Limiting cavities 211 are symmetrically opened on both the left and right sides of the inner wall of the spraying booth 1, and the limiting cavities 211 match the lifting seats 27. The up and down distance of the limiting cavities 211 is greater than the up and down movable distance of the lifting seats 27. The limiting cavities 211 can limit the lifting seats 27 to prevent the lifting seats 27 from shifting or rotating during use.

[0032] Embodiment Two:

[0033] On the basis of Embodiment One, in this embodiment, by controlling the forward rotation of the low-speed motor 37, the low-speed motor 37 can drive the moving seat 32 to move backward through the external threaded rod 33. The moving seat 32 will drive the aluminum profiles 4 to be sprayed to slowly move backward into the spraying booth 1 through the connecting vertical rod 35 and the supporting plate 36. Similarly, when controlling the reverse rotation of the low-speed motor 37, the moving seat 32 can drive the aluminum profiles 4 to be sprayed to slowly move forward through the connecting vertical rod 35 and the supporting plate 36, so that the left and right end faces of the aluminum profiles 4 to be sprayed can be fully sprayed by the spray gun 28.

[0034] The conveying assembly 3 includes a first support plate 31, a moving seat 32, an external threaded rod 33, a connecting vertical rod 35, a supporting plate 36, a low-speed motor 37 and a second support plate 38. The first support plate 31 is installed behind the spraying chamber 1. The first support plate 31 can support the low-speed motor 37 and the limiting rod 34. The low-speed motor 37 is installed on the upper side of the rear end face of the first support plate 31. When the low-speed motor 37 works, it can drive the external threaded rod 33 to rotate slowly. The front end of the low-speed motor 37 is connected to the external threaded rod 33. An internal threaded through hole is formed in the upper side of the moving seat 32, and the internal threaded through hole is engaged with the external threaded rod 33. The internal threaded through hole facilitates the forward or reverse rotation of the external threaded rod 33 to drive the moving seat 32 to move back and forth. The moving seat 32 is arranged on the circumferential side of the external threaded rod 33. The moving seat 32 can drive the connecting vertical rod 35 to move back and forth. The lower end face of the moving seat 32 is fixedly connected to the connecting vertical rod 35. The connecting vertical rod 35 is connected to both the moving seat 32 and the supporting plate 36 by welding. The connecting vertical rod 35 can support the supporting plate 36.

[0035] A plurality of supporting plates 36 are fixedly connected to the front end face of the connecting vertical rod 35. The plurality of supporting plates 36 can support a plurality of aluminum profiles 4 to be sprayed. The second support plate 38 is installed in front of the spraying chamber 1. The first support plate 31 and the second support plate 38 have the same height. The second support plate 38 can support the front end of the external threaded rod 33. A limiting rod 34 is fixedly connected between the first support plate 31 and the second support plate 38. The limiting rod 34 is connected to both the first support plate 31 and the second support plate 38 by welding. The limiting rod 34 can limit and guide the moving seat 32 to prevent the moving seat 32 from rotating or shaking during the forward and backward movement. A control panel is installed on the lower side of the front end face of the second support plate 38. The control panel is connected to the low-speed motor 37 and the spraying machine 21 through wires respectively. The control panel facilitates the staff to control the low-speed motor 37 and the spraying machine 21 according to needs. Since the detailed internal structure and working principle of the control panel belong to relatively mature technologies in the prior art, no more details will be described here.

[0036] Working principle: During the production of aluminum profiles, the staff first place a plurality of aluminum profiles 4 to be sprayed on the upper end faces of the plurality of supporting plates 36 (refer to Figure 1) After the placement is completed, the low-speed motor 37 can be controlled to rotate forward, so that the low-speed motor 37 drives the external threaded rod 33 to rotate forward together. The forward external thread will drive the moving seat 32 to move backward, and then the moving seat 32 drives the aluminum profile to be sprayed 4 to move slowly backward into the spraying room 1 through the connecting vertical rod 35 and the supporting plate 36. Then, the spraying machine 21 is started, so that the spraying machine 21 conveys the paint to the spray guns 28 on the left and right sides through the connecting tee pipe and the conveying hose 29. The spray guns 28 on the left and right sides will spray the conveyed paint outward to spray the left and right end faces of the aluminum profile to be sprayed 4 passing by. During this process, the axial flow fan 13 is started in advance, so that the axial flow fan 13 sucks and discharges most of the scattered paint mist in the spraying room 1 through the communication cavity 12 to avoid the paint mist from spreading to the outside and polluting the surrounding environment. At the same time, the servo motor 23 is started, so that the servo motor 23 drives the reciprocating lead screws 26 on the left and right sides to rotate synchronously and in the same direction through the worm 24 and the worm gear 25. The reciprocating lead screws 26 will drive the spray guns 28 on the left and right sides to move up and down synchronously to spray multiple aluminum profiles to be sprayed 4, and the slowly moving backward aluminum profile to be sprayed 4 also facilitates the spray guns 28 to spray its left and right end faces comprehensively. When the aluminum profile to be sprayed 4 moves backward out of the spraying room 1, the spraying machine 21 and the servo motor 23 can be stopped from working continuously. When the sprayed surface is dry, at this time, the aluminum profile to be sprayed 4 is turned 90 degrees and the low-speed motor 37 is controlled to rotate reversely, so that the supporting plate 36 drives the aluminum profile to be sprayed 4 to move forward and enter the spraying room 1 again. Immediately afterwards, the spraying machine 21 and the servo motor 23 are started again, and the spray guns 28 can spray the other two unsprayed surfaces of the aluminum profile to be sprayed 4, so as to spray the outer surface of the aluminum profile to be sprayed 4 comprehensively.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
