[0009] Preferably, a rotating column is fixedly connected to the bottom of the round box, and the bottom of the rotating column passes through the support plate and is rotatably connected to the support plate. A toothed ring is fixedly connected to the outer side of the bottom of the rotating column, and a rotating rod is rotatably connected to one side of the bottom of the support plate. A gear is fixedly installed on the outside of the rotating rod, and the gear is meshed with the toothed ring. A servo motor is fixedly connected to the bottom of the rotating rod.

[0010] Preferably, the painting assembly includes a conical frame disposed inside the housing, with an annular groove inside the conical frame, and atomizing nozzles embedded on the inner side of the conical frame. A paint pump is fixedly connected to one side of the top of the paint tank, and a connecting pipe is fixedly connected between the paint pump and the paint tank. A flexible hose is fixedly connected between the paint pump, the housing, and the conical frame. Fixed plates are symmetrically fixedly connected to both sides of the housing, and an electric telescopic rod is fixedly installed on the top of the fixed plate. A connecting plate is fixedly connected to the output end of the electric telescopic rod, and lifting rods are symmetrically fixedly connected to the bottom of the connecting plate.

[0013] Preferably, a feed pipe is fixedly connected to one side of the top of the paint tank.

[0014] Preferably, the first conical tooth and the second conical tooth are engaged in a meshing connection.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A painting device for lamp production, specifically comprising: a drive rod rotates at low speed driven by a forward and reverse motor; the rotation of the first conical tooth drives the rotation of the second conical tooth; the rotation of the second conical tooth drives two sets of bidirectional screws to rotate inside the sliding groove; the movement of the threaded block drives the movement of two sets of movable rods; the movement and rotation of the movable rods push the push plate to unfold; at this time, the two sets of arc-shaped plates unfold and squeeze and limit the inner side of the lampshade; the rubber pad is deformed by the compression, thereby achieving the effect of quickly fixing and limiting the lampshade, and meeting the positioning and painting effect of lampshades of various specifications, thus effectively preventing the lampshade from being sprayed during subsequent rotation. The painting process involves deviation and shaking, which greatly improves the stability and efficiency of lampshade painting and enhances the flexibility of equipment use. The operation of the electric telescopic rod drives the connecting plate to move downward, and the movement of the lifting plate moves the conical frame to the outside of the lampshade. Through the cooperation between the paint pump and the connecting pipe, the paint inside the paint tank is sucked into the hose, and then the paint is input into the inside of the annular groove through the hose. Finally, multiple sets of atomizing nozzles are used to spray the lampshade, thereby achieving a rapid adjustment and uniform spraying effect on the outside of the lampshade. The equipment, with its conical shape on the inside of the conical frame, can adapt to the surface curvature design of various lampshade specifications, thus greatly improving the surface spraying effect of the lampshade.

[0016] 1. The low-speed operation of the forward and reverse motor drives the rotation of the drive rod. The rotation of the drive rod drives the rotation of two sets of first conical teeth, which in turn drives the rotation of second conical teeth. The rotation of the second conical teeth drives two sets of bidirectional screws to rotate inside the sliding groove. The rotation of the bidirectional screws causes two sets of threaded blocks to move in a convergent-unfolding trajectory. At this time, one side of the threaded block slides against the inner side of the sliding groove. The movement of the threaded block drives the movement of two sets of movable rods. The movement and rotation of the movable rods push the push plate to unfold. When the output end of the forward and reverse motor reverses, the movable rod rotates and pulls the push plate to retract. The movement of the push plate drives the movement of the arc-shaped plate. At this time, the two sets of arc-shaped plates unfold and squeeze and limit the inner side of the lampshade. At this time, the rubber pad is subjected to... The extrusion deformation enables the rapid fixing and positioning of the lampshade, and can meet the positioning and painting effects of lampshades of various specifications. This effectively avoids the lampshade from shifting or shaking during subsequent rotational painting, thus greatly improving the stability and efficiency of lampshade painting and increasing the flexibility of equipment use. The operator starts the servo motor to drive the rotation of the rotating rod, which in turn drives the rotation of the gear, which in turn drives the rotation of the gear ring, which in turn drives the rotation of the rotating column, which in turn drives the rotation of the round box, which in turn drives the rotation of the arc plate and the lampshade. This achieves the effect of rotating the lampshade for painting, and greatly improves the uniform painting effect of the lampshade from multiple angles.

[0017] 2. The operation of the electric telescopic rod drives the connecting plate to move downwards. The downward movement of the connecting plate causes the two sets of lifting rods to slide inside the housing. The movement of the lifting rods causes the lifting plate to move, which in turn moves the conical frame to the outside of the lampshade. At this time, the operator drives the paint pump through the controller. Through the cooperation between the paint pump and the connecting pipe, the paint inside the paint tank is sucked into the hose, and then the paint is input into the annular groove through the hose. Finally, multiple sets of atomizing nozzles are used to spray the lampshade, thereby achieving a rapid adjustment and uniform spraying effect on the outside of the lampshade. The equipment, with its conical shape inside the conical frame, can adapt to the surface curvature design of various lampshade specifications, thus greatly improving the surface spraying effect of the lampshade and increasing the flexibility of equipment use.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a painting device for lamp production, comprising a box 1, a sealing door 101 hinged to one side of the front of the box 1, a paint box 102 fixedly connected to one side of the box 1, and a heating plate 103 fixedly connected to one side of the inside of the box 1; an adjustment mechanism 2 is provided inside the box 1, and a painting assembly 3 is provided on the top side of the inside of the box 1.

[0026] The adjustment mechanism 2 includes a support plate 201 fixedly installed on the bottom side inside the housing 1. A circular box 202 is provided on the top of the support plate 201, and a support column 203 is fixedly connected to the top of the circular box 202. Sliding grooves 204 are symmetrically opened on both sides of the support column 203. A drive rod 205 is rotatably connected inside the circular box 202. A bidirectional screw 206 is symmetrically rotatably connected between the circular box 202, the support column 203, and the sliding grooves 204. A first conical tooth 207 is symmetrically fixedly connected to the outside of the drive rod 205, and a second conical tooth 208 is fixedly connected to the bottom of the bidirectional screw 206.

The side of the push plate 212 is fixedly connected to an arc plate 213, and the outside of the arc plate 213 is fixedly connected to a rubber pad 214. This enables the device to quickly fix and limit the lampshade, and can meet the positioning and painting effect of lampshades of various specifications.

A servo motor 219 is fixedly connected to the bottom of the rotating rod 217, thereby realizing the effect of rotating the lampshade for painting, which can greatly improve the effect of uniform painting of the lampshade from multiple angles. A breathable and waterproof cover 220 is fixedly connected to the side of the round box 202 near the forward and reverse motor 209. The design of the breathable and waterproof cover 220 can prevent the forward and reverse motor 209 from being contaminated by paint. A collection groove 221 is opened on the top of the support plate 201. The design of the collection groove 221 can facilitate the collection of excess paint on the top of the support plate 201, making it convenient for staff to clean the residue later.

[0028] The painting assembly 3 includes a conical frame 301 disposed inside the housing 1, with an annular groove 302 inside the conical frame 301. Atomizing nozzles 303 are embedded on the inner side of the conical frame 301. A paint pump 304 is fixedly connected to one side of the top of the paint tank 102, and a connecting pipe 305 is fixedly connected between the paint pump 304 and the paint tank 102. A flexible hose 306 is fixedly connected between the paint pump 304, the housing 1, and the conical frame 301. Fixing plates 307 are symmetrically fixedly connected to both sides of the housing 1. An electric telescopic rod 308 is fixedly installed on the top of the fixing plate 307, and a connecting plate 309 is fixedly connected to the output end of the electric telescopic rod 308. The bottom of the connecting plate 309 is symmetrically fixed... A lifting rod 310 is connected, and the bottom of the lifting rod 310 passes through the box body 1 and is slidably connected to the box body 1. A lifting plate 311 is fixedly connected to the bottom of the lifting rod 310, and the bottom of the lifting plate 311 is fixedly connected to the conical frame 301. A feed pipe 312 is fixedly connected to the top side of the paint box 102, thereby enabling the effect of quickly adjusting and uniformly spraying the exterior of the lampshade. The device, with its conical shape inside the conical frame 301, can adapt to the surface curvature design of various specifications of lampshades, thereby greatly improving the surface spraying effect of the lampshade and increasing the flexibility of the equipment during use. The design of the feed pipe 312 facilitates the addition of paint to the paint box 102 by the operator.

[0029] Working principle: Before using this type of painting equipment for lamp production, it is necessary to check the overall condition of the equipment to ensure that it can work normally. Figure 1 - Figure 5As shown, the operator first places the equipment in a suitable area, then opens the sealed door 101 and places the lampshade on top of the support plate 201. When the lampshade is placed outside the two sets of arc plates 213, the operator drives the forward and reverse motors 209 through the controller. The low-speed operation of the forward and reverse motors 209 drives the drive rod 205 to rotate. The rotation of the drive rod 205 drives the rotation of the two sets of first conical teeth 207. The rotation of the first conical teeth 207 drives the rotation of the second conical teeth 208. The rotation of the second conical teeth 208 drives the two sets of bidirectional screws 206 to rotate inside the sliding groove 204. The rotation of the motor causes the two sets of threaded blocks 210 to move in a convergent and unfolding trajectory. At this time, one side of the threaded block 210 slides against the inner side of the sliding groove 204. The movement of the threaded block 210 causes the two sets of movable rods 211 to move. The movement and rotation of the movable rods 211 push the push plate 212 to unfold. When the output end of the forward and reverse motor 209 reverses, the movable rod 211 rotates and pulls the push plate 212 to retract. The movement of the push plate 212 causes the arc plate 213 to move. At this time, the two sets of arc plates 213 unfold and squeeze and limit the inner side of the lampshade. At this time, the rubber pad 214 is deformed by the compression, thereby achieving the effect of quickly fixing and limiting the lampshade. This method achieves the desired effect of positioning and painting various sizes of lampshades, effectively preventing displacement and wobbling during subsequent rotational painting. This significantly improves the stability and efficiency of lampshade painting, enhancing the flexibility of equipment use. The operator starts the servo motor 219, which drives the rotating rod 217. The rotation of the rotating rod 217 drives the gear 218, which in turn drives the gear ring 216. The gear ring 216 then drives the rotating column 215, which in turn drives the circular box 202. The rotation of the circular box 202 then drives the arc plate 213 and the lampshade... The rotation of the cover enables the lampshade to rotate and spray paint, which greatly improves the uniform spraying effect of the lampshade from multiple angles. The design of the breathable and waterproof cover 220 can prevent the forward and reverse motors 209 from being contaminated by paint. The design of the collection tank 221 makes it easy to collect excess paint on the top of the support plate 201, which is convenient for the staff to clean the residue later. After the lampshade is painted, the staff drives the heating plate 103 to a suitable temperature through the controller to dry the outside of the lampshade. The temperature sensor set inside the box 1 and the exhaust port on the top of the box 1 are used to monitor the heating temperature.

[0030] The two sets of electric telescopic rods 308 are driven synchronously by the operator's controller. The operation of the electric telescopic rods 308 causes the connecting plate 309 to move downward. The downward movement of the connecting plate 309 causes the two sets of lifting rods 310 to slide inside the housing 1. The movement of the lifting rods 310 causes the lifting plate 311 to move. The movement of the lifting plate 311 causes the conical frame 301 to move to the outside of the lampshade. At this time, the operator drives the paint pump 304 through the controller. Through the cooperation between the paint pump 304 and the connecting pipe 305, the paint inside the paint tank 102 is sucked into the hose 306. Paint is fed into the annular groove 302 through the hose 306, and finally sprayed onto the lampshade using multiple sets of atomizing nozzles 303. This allows for rapid adjustment and uniform spraying of the lampshade exterior. The conical frame 301, with its conical inner side, is designed to accommodate the surface curvature of various lampshade specifications, thereby greatly improving the spraying effect on the lampshade surface and enhancing the flexibility of equipment use. The feed pipe 312 facilitates the addition of paint to the paint tank 102 by the operator. All pipe structures in the painting assembly 3 are equipped with sealing structures.
