Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0016] Please see Figures 1-5 In one embodiment of this application, a ventilation duct anti-rust paint spraying device includes a base 1, a paint storage tank 2, a plurality of casters 3, and a controller 4. The paint storage tank 2 is mounted on the base 1, the controller 4 is mounted on the paint storage tank 2, and the plurality of casters 3 are symmetrically arranged on the base 1. The spraying device further includes: Mounting base 10 is movably mounted on base 1, and a plurality of conveying rollers 11 are evenly and movably arranged on mounting base 10; A drive roller 6 is movably mounted on a base 1. A limit strip 7 is provided on one side of the drive roller 6. A motor 5 connected to the drive roller 6 is provided on the base 1. Material conveying module 9, mounted on base 1 and connected to paint storage tank 2, is used to spray anti-rust paint onto the surface of ventilation ducts; and The adjustment module 13 is mounted on the base 1 and connected to the mounting base 10, and is used to adjust the position of the mounting base 10; wherein The adjustment module 13 includes: The rotating shaft 133 is movably mounted on the base 1 and one end is connected to the mounting base 10; The second motor 135 is mounted on the base 1. Both the output end of the second motor 135 and the base 1 are equipped with a transmission disc 132. The transmission discs 132 are connected by a belt. The inner wall of the transmission disc 132 on the base 1 is provided with a retaining strip 136. The rotating shaft 133 is formed with a retaining groove 137 that slides with the retaining strip 136. Abutment rod 134 is mounted on rotating shaft 133; and A trapezoidal disk 131 is mounted on the base 1, and the inclined surface formed on the trapezoidal disk 131 is in sliding engagement with the abutment rod 134.

[0017] In this embodiment, a damping sleeve 8 is provided on the drive roller 6, and the end of the damping sleeve 8 away from the limiting strip 7 is provided with a chamfer.

[0018] It should be noted that the height adjustment of the mounting base 10 is not limited to the cooperation between the trapezoidal plate 131 and the abutment rod 134 mentioned above. A linear motor or electric cylinder drive can also be used instead, which will not be listed here.

[0019] In practical applications, the controller 4 controls the movement of the No. 1 motor 5 and the conveying roller 11. By placing the ventilation duct on the conveying roller 11, the conveying roller 11 pulls the ventilation duct toward the drive roller 6 until the drive roller 6 extends into the inside of the ventilation duct. At this point, the ventilation duct detaches from the conveying roller 11 and falls onto the drive roller 6. The rotation of the No. 1 motor 5 drives the drive roller 6 and the damping sleeve 8 to rotate. Under the action of the frictional resistance between the damping sleeve 8 and the ventilation duct, the ventilation duct can be driven to rotate synchronously. At the same time as the drive roller 6 rotates, the material conveying module 9 can work synchronously. The material conveying module 9 sprays the anti-rust paint in the paint storage tank 2 onto the ventilation duct. After the anti-rust paint is applied to the surface of the ventilation duct, the No. 2 motor 135 is powered on. Through the cooperation between the clamping strip 136 and the clamping groove 137, the rotating shaft 133 and the mounting base 10 are driven to rotate, causing the mounting base 10 to rotate 180°. Under the sliding cooperation between the contact rod 134 and the trapezoidal disk 131, the mounting base 10 moves downward while rotating, so that the conveying roller 11 just contacts the surface of the painted ventilation duct. At this time, the rotation of the conveying roller 11 can smoothly discharge the painted ventilation duct and separate it from the drive roller 6, realizing automatic feeding and unloading, reducing the amount of labor input.

[0020] Please see Figure 1 as well as Figure 5 In another preferred embodiment of this application, the material conveying module 9 includes: A plurality of nozzles 93 are arranged in an array on the base 1, with the plurality of nozzles 93 located on one side of the drive roller 6; and An actuation component is disposed between the nozzle 93 and the paint storage tank 2, and is used to input the anti-rust paint in the paint storage tank 2 into the nozzle 93. The actuation component is connected to the drive roller 6.

[0021] In this embodiment, the execution component, as executively shown, includes: The drive disk 91 is movably mounted on the base 1; A material conveying box 95 is set on the base 1. The material conveying box 95 is provided with an input hole 1213 and an output hole 1212. A one-way valve 94 is provided in both the input hole 1213 and the output hole 1212. The input hole 1213 and the output hole 1212 are respectively connected to the paint storage tank 2 and the spray head 93. Piston 96 rod, movably disposed within conveyor box 95 and elastically connected to it; and The drive arm 92 is movably connected between the piston rod 96 and the drive disc 91 at an eccentric position.

[0022] It should be noted that this embodiment is not limited to the above-mentioned execution components to control the anti-rust paint in the paint storage tank 2 to enter the nozzle 93 and spray it out. Centrifugal pumps or gear pumps can also be used instead, which will not be listed here.

[0023] During the process of the No. 1 motor 5 controlling the rotation of the drive roller 6 to drive the ventilation duct to move, the drive disc 91 can be driven to rotate synchronously. Under the action of the drive arm 92, the piston rod 96 can be driven to reciprocate along the conveying box 95, so that the anti-rust paint in the paint storage box 2 is drawn into the conveying box 95 and finally discharged into the spray nozzle 93 and sprayed onto the surface of the ventilation duct, thereby realizing the anti-rust treatment of the surface of the ventilation duct.

[0024] Please see Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As another preferred embodiment of this application, the spraying device further includes a material discharge auxiliary module 12, which is disposed between the mounting base 10 and each material conveying roller 11, for adjusting the contact area between the material conveying roller 11 and the ventilation duct after the painting is completed.

[0025] In one specific embodiment, the material discharge auxiliary module 12 includes: The ejector bar 127 has several grooves formed at equal intervals on the conveying roller 11. The ejector bar 127 is a number of grooves arranged in a ring in the grooves. One end of the ejector bar 127 is hinged to the inner wall of the groove. The number of sliders 129 is the same as the number of ejector bars 127 and they are arranged in a ring in the groove. The sliders 129 are movably connected to the other end of the ejector bars 127 via push rods 128. Slide bar 1210 is movably disposed in a cavity 1211 formed within the conveying roller 11, and slide bar 1210 is connected to slider 129; and An inflation module is disposed between the mounting base 10 and the base 1. When the mounting base 10 moves, it controls the inflation module to work and inputs air into the cavity 1211.

[0026] In another specific embodiment, the inflation module includes: A hollow tube 124 is mounted on a mounting base 10. The conveying roller 11 is provided with a plurality of input holes 1213. An output hole 1212 communicating with the input holes 1213 is provided in the cavity 1211. The hollow tube 124 is connected to the input holes 1213 through an exhaust pipe 126. Skateboard 125, movable within hollow tube 124; and A slide bar 121 is movably mounted on a mounting base 10 and the two are connected by an elastic element. One end of the slide bar 121 is movably mounted with a roller 123, and the other end of the slide bar 121 is connected to a sliding plate 125.

[0027] It should be noted that the mechanical structure described above is not used to adjust the air pressure in the cavity 1211 in this embodiment. A fan or air pump can also be used instead, but they will not be listed here.

[0028] In addition, the elastic element can be a spring 122, a spring sheet, or an elastic steel plate structure. In this embodiment, the elastic element is preferably a spring 122. The spring 122 is connected between the slide rod 121 and the mounting base 10. The specific model parameters of the spring 122 can be selected according to the actual situation, and are not specifically limited here.

[0029] When the second motor 135 drives the mounting base 10 to rotate so that the mounting base 10 and the conveying roller 11 reach directly below the drive roller 6, the mounting base 10 moves down, causing the slide rod 121 to move up relative to the hollow tube 124, thereby driving the slider 129 to move synchronously, squeezing the air in the hollow tube 124 into the cavity 1211, thereby driving the slider 129 to move along the cavity 1211, and thus, under the action of the push rod 128, driving the ejector bar 127 to extend out of the groove, thereby discharging the painted ventilation duct through the conveying roller 11. By avoiding direct contact between the conveying roller 11 and the outer wall of the ventilation duct, the quality of the anti-rust paint spraying on the outer wall of the ventilation duct can be guaranteed.

[0030] How this application works: The controller 4 controls the movement of the first motor 5 and the conveying roller 11. By placing the ventilation duct on the conveying roller 11, the conveying roller 11 pulls the ventilation duct toward the drive roller 6 until the drive roller 6 extends into the inside of the ventilation duct. At this time, the ventilation duct detaches from the conveying roller 11 and falls onto the drive roller 6. The first motor 5 rotates, driving the drive roller 6 and the damping sleeve 8 to rotate. Under the action of the frictional resistance between the damping sleeve 8 and the ventilation duct, the ventilation duct can be driven to rotate synchronously. During the process of the first motor 5 controlling the rotation of the drive roller 6 to drive the ventilation duct to move, the drive disc 91 can be driven to rotate synchronously. Under the action of the drive arm 92, the piston 96 rod can be driven to reciprocate along the conveying box 95, so that the anti-rust paint in the paint storage box 2 is drawn into the conveying box 95 and finally discharged into the spray nozzle 93 and sprayed onto the surface of the ventilation duct, realizing the spray anti-rust treatment of the surface of the ventilation duct. After the anti-rust paint is applied to the ventilation duct, the No. 2 motor 135 is powered on. Through the cooperation between the clamping strip 136 and the clamping groove 137, the rotating shaft 133 and the mounting base 10 are driven to rotate, causing the mounting base 10 to rotate 180°. Under the sliding cooperation between the contact rod 134 and the trapezoidal disk 131, the mounting base 10 moves downward while rotating, so that the conveying roller 11 just contacts the surface of the painted ventilation duct. At this time, the rotation of the conveying roller 11 can smoothly discharge the painted ventilation duct and separate it from the drive roller 6, realizing automatic feeding and unloading, reducing the amount of labor input. When the second motor 135 drives the mounting base 10 to rotate so that the mounting base 10 and the conveying roller 11 reach directly below the drive roller 6, the mounting base 10 moves down, causing the slide rod 121 to move up relative to the hollow tube 124, thereby driving the slider 129 to move synchronously, squeezing the air in the hollow tube 124 into the cavity 1211, thereby driving the slider 129 to move along the cavity 1211, and thus, under the action of the push rod 128, driving the ejector bar 127 to extend out of the groove, thereby discharging the painted ventilation duct through the conveying roller 11. By avoiding direct contact between the conveying roller 11 and the outer wall of the ventilation duct, the quality of the anti-rust paint spraying on the outer wall of the ventilation duct can be guaranteed.
