Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spraying, specifically to a coating equipment for production. BACKGROUND

[0002] Guardrails are usually exposed to outdoor environments and face various corrosion factors such as rain, humid air, sunlight ultraviolet rays, and chemical substances (such as acid rain, industrial waste gas, etc.). Metal guardrails (such as steel guardrails) are prone to rust, wooden guardrails may rot, and even some new composite material guardrails may be affected by environmental factors and have decreased performance. Spraying anticorrosive paint can form a protective film on the surface of the guardrail, isolating external corrosion factors and extending the service life of the guardrail. For example, a double-layer spraying system using zinc powder primer and polyurethane topcoat can provide good corrosion protection for steel guardrails.

[0003] With the rapid development of automation and intelligent technology, such as robot technology, sensor technology, and computer control systems, these technologies make it possible to efficiently complete guardrail coating production. For example, a coating production line disclosed in a Chinese patent with publication number CN112705394B includes a conveying device and, in sequence, a pretreatment device, a spraying device, and a curing device on the conveying device. The pretreatment device can clean the surface of the workpiece, and the curing device can dry and cure the surface of the workpiece after spraying. The spraying device includes a body, a spraying mechanism, and a rotating mechanism. The rotating mechanism includes a rotating part, a shaft, a turntable, several support rods, and two semicircular connecting plates. One end of the shaft is rotatably connected to the bottom wall of the feeding channel, and the other end is arranged on the turntable. The several support rods are vertically arranged on the turntable, and the two connecting plates are arranged on the support rods. The far end from the turntable is arranged on both sides of the feeding channel. The rotating part is arranged on the bottom wall of the feeding channel and can rotate the shaft. The spraying mechanism is arranged on the support rods and can spray between the two connecting plates. This application can make the surface spraying of the product more uniform.

[0004] From the above patent disclosure, it can be seen that by setting the spraying mechanism and the rotating mechanism, the spraying mechanism can be controlled to spray around the object to be sprayed, i.e. when the hanging object penetrates the spraying device and stays for a short time, the complete spraying process can be completed by the spraying mechanism. However, the work efficiency of the above-mentioned spraying mechanism can be further improved, because only one set of spraying mechanism is provided in the spraying device, which means that when spraying a batch of objects, each object will consume time due to the stay.

The structure of the spraying device is specifically introduced below.

[0028] As shown in Figure 1 , the spraying device comprises a frame 1 and a spraying assembly 2.

[0029] As shown in Figure 2 , the frame 1 comprises a bottom box 13 and a hole shell 12. The bottom box 13 is arranged as a rectangular shell structure, and a feeding hole 16 is arranged on the vertical side of the bottom box 13, and the spraying material can be added to the bottom box 13 through the feeding hole 16. In order to realize the closure of the bottom box 13, the plug plate 17 is arranged on the side of the feeding hole 16, specifically, the screw rod is arranged on the side wall of the bottom box 13, the screw rod penetrates the plug plate 17 and is arranged, and the nut is threadedly sleeved on the end of the screw rod, so that the plug plate 17 is pressed and matched with the bottom box 13 under the action of the nut. The hole shell 12 is arranged as an inverted U-shaped structure, and the lower end is connected with the top surface of the bottom box 13, that is, the transmission device can be conveniently penetrated and installed, and then the articles are brought in and out of the hole shell 12.

[0030] As shown in Figure 1 , Figure 3As shown, the spraying assembly 2 is positioned above the base box 13 and at the bottom of the cavity shell 12. It includes a support plate 22, a motor 21, and multiple sets of spraying devices 24. The support plate 22 is positioned along the length of the frame 1 and is located in the middle of the base box 13. Both ends of the support plate 22 are connected to the base box 13. Multiple sets of spraying devices 24 are distributed along the length of the support plate 22. Each set of spraying devices 24 has a connecting mechanism 25 at its bottom. A support shaft 26 is located below the connecting mechanism 25. The bottom of the support shaft 26 is inserted into the support plate 22 via a bearing connection, facilitating the control of the spraying devices 24 to rotate around the shaft. A sprocket 261 is provided on each support shaft 26 and the motor 21. Adjacent sprockets 261 are connected by a chain. Therefore, under the operation of the motor 21, multiple support shafts 26 can be controlled to rotate synchronously, thereby controlling the rotation of multiple sets of spraying devices 24. That is, the spraying devices 24 spray the workpiece around it.

[0031] like Figure 1 As shown, in order to control the material to be conveyed from the bottom box 13 to the spraying device 24, a pump 11 is provided on the outside of the bottom box 13.
