Description

Technical Field

[0001] This utility model relates to the field of sign processing technology, and in particular to a sign processing and painting device. Background Technology

[0002] A spray painting system is a specialized device used to evenly apply paint or other coatings to the surface of an object. It is widely used in various fields such as automobile manufacturing, furniture production, home appliance coating, building decoration, and signage processing. Depending on the level of automation and application, spray painting systems can be categorized into manual, semi-automatic, and fully automatic types. The spray painting system used in signage processing is specifically designed for signage surface treatment. Its main responsibility is to evenly spray paint or other coatings onto the signage surface, ensuring good visual appeal and durability.

[0003] Existing sign painting equipment has certain limitations in handling sign painting. Current equipment can typically only effectively paint the top of the sign. When painting the sides of the sign is required, the sign's position or clamping method must be readjusted. This not only increases operational complexity and time costs but also leads to positioning errors due to repeated processing, affecting the consistency of the final product's quality. Furthermore, for signs with low heights, the fixed nozzle installation position cannot be flexibly adjusted according to the actual size of the sign. This forces operators to use a more extensive painting method, requiring the nozzle to apply more paint than needed to ensure complete coverage of the sign's surface. This results in unnecessary paint waste, increases processing costs, and is also detrimental to environmental protection. Utility Model Content

[0004] The purpose of this utility model is to provide a sign processing and painting device that can avoid the problems of existing sign painting devices, which can only effectively paint the top, require repositioning and clamping on both sides, and have fixed nozzle positions, resulting in wasted pigment when painting low-height signs, increased operation complexity, time and cost, affected product quality consistency, and increased processing costs and environmental burden.

A receiving box is fixedly connected to the inner cavity of the spray booth.

[0009] In one specific implementation, a storage box is fixedly connected to the bottom of the paint spraying box, a protective rod is provided at the bottom of the inner cavity of the receiving box, and a rotating disk is rotatably connected to the bottom of the inner cavity of the paint spraying box, with the bottom end of the rotating disk penetrating into the inner cavity of the storage box.

[0010] In one specific implementation, the top of the rotating disk is fixedly connected to the bottom of the protective rod, and a second motor is installed in the inner cavity of the storage box. The output shaft of the second motor and the surface of the rotating disk are respectively connected to pulleys, and the two pulleys are connected by belt drive.

[0011] In one specific implementation, telescopic rods are fixedly connected to both the left and right sides of the top of the rotating disk. The output end of the telescopic rod extends through to the outside of the top of the protective rod and is fixedly connected to a placement disk.

[0013] In one specific implementation, the surface of the second threaded rod is rotatably connected to the inner cavity of the rotating disk via a bearing, and the bottom end of the second threaded rod and the output shaft of the third motor are respectively connected to two meshing bevel gears.

[0014] In one specific implementation, the outer surface of the second threaded rod is threaded with a top rod, the top end of which extends to the outside of the top of the protective rod and is rotatably connected to the bottom of the placement tray via a bearing.

[0015] The beneficial effects of this application are as follows: By setting up the movable components, this painting device can effectively meet the painting needs of signs of different heights.

[0026] Existing sign painting equipment suffers from several drawbacks. It can only effectively paint the top, requires repositioning and clamping on both sides, and has a fixed nozzle position, leading to wasted paint on low-height signs. This increases operational complexity, time, and cost, affects product quality consistency, and raises processing costs and environmental burden. Therefore, the inventors have developed a sign painting device that, through the design of a moving component, not only achieves lifting and rotation adjustment of the sign to ensure comprehensive and uniform painting, but also precisely controls the distance between the nozzle and the sign, reducing paint waste, lowering costs, improving efficiency and product quality consistency, simplifying the process, and making the painting process more efficient and environmentally friendly, thus solving the aforementioned shortcomings.

[0027] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please refer to Figures 1 to 8This utility model provides a sign processing and painting device, including a paint spraying box 1. A movable component 2 is provided inside the paint spraying box 1. A door made of tempered glass is rotatably connected to the front of the paint spraying box 1 to facilitate user observation of the painting progress. The movable component 2 includes an electric guide rail 21, the surface of which is fixedly connected to the top of the paint spraying box 1. A fixed box 22 is movably connected to the bottom of the electric guide rail 21. A welding box 23 is fixedly connected to the inner cavity of the fixed box 22. A first motor 24 is installed inside the welding box 23. A movable first threaded rod 25 is rotatably connected to the inner cavity of the fixed box 22. The outer surface of the first threaded rod 25 has an external thread for driving the internal thread. A threaded block 26 is threadedly connected to the outer surface of the first threaded rod 25. The area in contact with the first threaded rod 25 is provided with a matching internal thread, and the surface of the fixed box 22 is provided with a cavity for the threaded block 26 to move through. The surface of the threaded block 26 is slidably connected to the inner cavity of the fixed box 22. A positioning block 27 is fixedly connected to the surface of the threaded block 26. Long blocks 28 are fixedly connected to the front and rear sides of the bottom of the fixed box 22. Several nozzles 29 are respectively installed on the surface of the long blocks 28 and the positioning blocks 27. A paint pump 210 is installed on the top of the rear side of the paint spray box 1. The discharge end of the paint pump 210 is connected to a pipe 211, and the end of the pipe 211 away from the paint pump 210 passes through the inner cavity of the paint spray box 1 and is connected to the nozzles 29. The pipe 211 is a flexible hose, and the inlet end of the paint pump 210 is connected to a pipeline for easy connection with an external pigment storage device.

[0029] Please refer to Figures 2 to 8A receiving box 226 is fixedly connected to the inner cavity of the spray paint box 1. A discharge pipe is connected to the rear side of the receiving box 226 for easy discharge, and a valve is installed on the surface of the discharge pipe to facilitate the discharge of liquid and waste accumulated in the receiving box 226. A storage box 212 is fixedly connected to the bottom of the spray paint box 1. A protective rod 213 is installed at the bottom of the inner cavity of the receiving box 226. A rotating disk 214 is rotatably connected to the bottom of the inner cavity of the spray paint box 1. The bottom end of the rotating disk 214 penetrates into the inner cavity of the storage box 212, and the area of ​​contact between the rotating disk 214 and the storage box 212 is sealed to prevent liquid leakage into the inner cavity of the storage box 212, thus protecting the internal parts of the storage box 212. The top of the rotating disk 214 is fixedly connected to the bottom end of the protective rod 213. A second motor 216 is installed in the inner cavity of the storage box 212. Pulleys 215 are respectively connected to the output shaft of the second motor 216 and the surface of the rotating disk 214. Each pulley 215 is connected via belt drive. Telescopic rods 217 are fixedly connected to the left and right sides of the top of the rotating disk 214. The telescopic rods 217 are installed in the inner cavity of the protective rod 213. The output end of the telescopic rod 217 extends to the outer side of the top of the protective rod 213 and is fixedly connected to the placement disk 218. The contact area between the telescopic rod 217 and the placement disk 218 is sealed. Clamps 219 are bolted to both sides of the top of the placement disk 218. The clamps 219 can be selected as tiger head clamps or other fixed clamping devices to facilitate the clamping and rotation of smaller signs. Cylinders 220 are fixedly connected to the left and right sides of the paint spray box 1. The output end of the cylinder 220 extends to the inner cavity of the paint spray box 1 and is fixedly connected to the pressure plate 221. The pressure plate 221 and the cylinder 220 are designed for signs that only need to be painted on the front, back, and top sides and do not require rotation for painting. This facilitates the painting of longer signs.

[0030] Please refer to Figures 2 to 7The storage box 212 has a third motor 222 installed inside its cavity. The second threaded rod 223 extends through the cavity of the storage box 212, and the top end of the second threaded rod 223 extends into the cavity of the receiving box 226. The contact area between the second threaded rod 223 and the receiving box 226 is sealed. The outer surface of the second threaded rod 223 has external threads. The surfaces of the first threaded rod 25 and the second threaded rod 223 are treated for rust and corrosion prevention. The surface of the second threaded rod 223 is rotatably connected to the inner cavity of the rotating disk 214 via bearings, thereby preventing the rotating disk 214 from driving the second threaded rod 223 during rotation. The threaded rods 223 rotate together. The bottom end of the second threaded rod 223 and the output shaft of the third motor 222 are respectively connected to two meshing bevel gears 224. The outer surface of the second threaded rod 223 is threaded with a push rod 225. The area where the push rod 225 contacts the second threaded rod 223 is provided with a matching internal thread. The internal thread is treated for corrosion and rust prevention. The top end of the push rod 225 extends to the outside of the top end of the protective rod 213 and is rotatably connected to the bottom of the placement plate 218 through a bearing, so as to prevent the placement plate 218 from rotating while driving the push rod 225 to rotate together.

[0031] Specifically, when painting smaller or wider signs, the sign is first placed on the placement tray 218. For smaller signs, a clamp 219 is used to hold the surface in place for rotary painting, and the second motor 216 is started. This motor drives the pulley 215 to rotate, causing the rotating tray 214, the guard bar 213, and the telescopic bar 217 to rotate as well, thereby rotating the placement tray 218 and the sign on it to complete the all-around painting operation. For wider signs, the cylinder 220 is started, and its output end pushes the pressure plate 221 to firmly clamp the sides of the sign, ensuring that the painting is carried out smoothly. During the painting process, the sign's position remains fixed. For signs of different heights, the third motor 222 is activated, driving the bevel gear 224 to mesh and rotate. This causes the second threaded rod 223 to rotate, using the threaded transmission principle to move the placement tray 218 along with the sign upwards. Simultaneously, the telescopic rod 217 moves synchronously. When the placement tray 218 moves to the appropriate position below the fixed box 22, the paint pump 210 starts working, transferring paint to multiple nozzles 29 for spraying. To achieve uniform spraying of the sign's front and back, the first motor 24 starts, driving the first threaded rod 25 to rotate, which in turn pushes the threaded block 26 to move in the front-back direction through the threaded transmission principle. The threaded block 26 drives the positioning block 27 to move synchronously, and finally, the positioning block 27 carries the nozzles 29 to spray the sign back and forth. If it is necessary to spray the left and right sides of the sign, the left and right reciprocating movement function of the nozzles 29 and the electric guide rail 21 is combined to ensure that both sides are also fully covered.

[0032] In summary, the working principle of the sign processing and painting device of this utility model embodiment is as follows: First, the user places the sign on the moving component 2, and then starts the moving component 2 to adjust the height of the spray nozzle 29 for signs of different heights. After adjustment, the moving component 2 is started to spray the top and both sides of the sign evenly, thereby achieving the purpose of sign spraying. Furthermore, for some round signs, the moving component 2 can also drive the round sign to rotate, thereby achieving the purpose of even spraying, which is convenient to use.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
