[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 As shown, this utility model provides an electrostatic spraying device for aluminum profile manufacturing, including a workbench 1, a spraying machine 101 mounted on the end face of the workbench 1, a conduit 102 connected to the side wall of the spraying machine 101, the end of the conduit 102 away from the spraying machine 101 passing through the workbench 1 and connected to a spraying frame 103, a plurality of spray nozzles 104 mounted on the bottom of the spraying frame 103, a rectangular hole 105 opened on the surface of the workbench 1, an auxiliary mechanism 2 provided on the side wall of the workbench 1, the auxiliary mechanism 2 including a base 201 fixedly connected to the side wall of the workbench 1, a motor 202 fixedly connected to the surface of the base 201, a plurality of long rods 203 rotatably connected to the inner wall of the rectangular hole 105, and a rubber roller 204 fixedly connected to the arc surface of the long rods 203.

[0023] In this embodiment, both the sprayer 101 and the spray nozzle 104 are existing equipment, and will not be described in detail here.

[0024] In an optional embodiment: one end of each of the plurality of long rods 203 is fixedly connected to a sprocket 205, one of which is fixedly connected to the output end of the motor 202, and the teeth of the plurality of sprockets 205 are engaged with a chain 206.

[0025] It should be noted that when the motor 202 is started, the motor 202 drives one of the sprockets 205 to rotate. Under the transmission of the chain 206, multiple sprockets 205 will rotate synchronously, thereby causing the rubber roller 204 to rotate. The aluminum plate is moved by the friction of the rubber roller 204.

[0026] In an optional embodiment: a screw 207 is threadedly connected to the side wall of the workbench 1, and a rectangular plate 208 is rotatably connected to one end of the screw 207.

[0027] In an optional embodiment: a plurality of fixing blocks 209 are fixedly connected to the side of the rectangular plate 208 away from the screw 207, and pulleys 210 are rotatably connected to the surface of the fixing blocks 209.

[0028] In an optional embodiment: a limiting rod 211 is fixedly connected to the side of the rectangular plate 208 away from the pulley 210, and the end of the limiting rod 211 away from the rectangular plate 208 slides through the worktable 1.

[0029] It should be noted that when screwing the screw 207, the screw 207 drives the rectangular plate 208 to move via the thread. The movement of the rectangular plate 208 causes the limiting rod 211 to slide along the surface of the worktable 1. The limiting rod 211 restricts the position of the rectangular plate 208 until both sides of the aluminum plate contact the pulley 210. The movement of the aluminum plate will cause the pulley 210 to rotate, and the pulley 210 will reduce the friction on both sides of the aluminum plate.

[0030] In an optional embodiment: a support platform 212 is fixedly connected to one side of the workbench 1, and the cross-sectional shape of the support platform 212 is triangular.

[0031] It should be noted that, under the action of the support platform 212, the aluminum plate can be temporarily supported and buffered after the aluminum plate is sprayed.

[0032] The working principle of this utility model is as follows: In use, the operator places the aluminum plate on multiple rubber rollers 204 and turns the screws 207 on both sides. The screws 207, driven by the threads, move the rectangular plate 208. The movement of the rectangular plate 208 causes the limiting rod 211 to slide along the surface of the workbench 1. The limiting rod 211 restricts the position of the rectangular plate 208 until both sides of the aluminum plate contact the pulley 210. It is not necessary to clamp the aluminum plate; only the aluminum plate needs to be limited. By starting the motor 202, the motor 202 drives one of the sprockets 205 to rotate. Under the transmission of the chain 206, multiple sprockets 205 will rotate synchronously, thereby causing the rubber rollers 204 to rotate. The friction of the rubber rollers 204 causes the aluminum plate to move. The movement of the aluminum plate causes the pulley 210 to rotate. The pulley 210 reduces the friction on both sides of the aluminum plate. Then, the spraying machine 101 is started, and the spray nozzle 104 sprays the aluminum plate, achieving uniform coating.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
