[0018] 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.
[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0020] Combination Figure 1 This utility model discloses a surface painting device for steel processing, comprising a paint spraying box 1, a paint spraying conveying mechanism 2 fixedly installed inside the paint spraying box 1, a negative pressure fixing mechanism 3 for receiving paint waste correspondingly installed at the lower end of the paint spraying conveying mechanism 2, and a paint spraying robot arm 4 for spraying correspondingly installed at the upper end of the paint spraying conveying mechanism 2. The paint spraying box 1 includes a box body 11, and side openings 12 are opened on both sides of the box body 11 corresponding to the paint spraying conveying mechanism 2. The paint spraying conveying mechanism 2 includes a conveying frame 21 fixedly connected to the box body 11. Two sets of sliding sleeves 23 and two sets of adjusting discs 24 are fixedly installed on both sides of the conveying frame 21. Two sets of transmission components 22 are slidably sleeved on the sliding sleeves 23. The two sets of transmission components 22 and the two sets of adjusting discs 24 are respectively connected one-to-one by threaded connection. A motor component 26 for driving is connected to one side of one set of transmission components 22. Rotatable rotating connecting rods 25 are symmetrically arranged at the lower ends of the two sets of transmission components 22. The two sets of transmission components 22 rotate synchronously through the rotating connecting rods 25.
[0021] Specifically, the side openings 12 on both sides of the housing 11 facilitate the conveying of steel plates into the housing 11 via the paint conveying mechanism 2 to complete the painting. The motor 26 drives a set of transmission components 22 to complete the conveying. This set of transmission components 22 then drives the rotating connecting rod 25 to rotate, thereby driving another set of transmission components 22. The synchronous movement of the two sets of transmission components 22 can move the steel plate placed on top of them. The steel plate is put in from one side and stops moving inside the housing 11 to complete the painting. Then it continues to move outward to convey the painted steel plate, realizing an automated process, preventing workers from being in the painting environment, and improving safety. The sliding sleeve 23 provides sliding guidance for the two sets of transmission components 22 to maintain the stability of the transmission components 22. The two sets of adjusting discs 24 are used to adjust the two sets of transmission components 22 that are threaded to them, realizing the adjustment of the spacing of the transmission components 22 to adapt to changes in the size of the steel plate. The adjusting discs 24 in this device are set on both sides of the paint box 1 to realize external adjustment of the paint conveying mechanism 2 and improve the protection effect.
[0022] The present invention will be further described below with reference to the embodiments.
[0023] Example 1: Combination Figures 2-4 The box body 11 has two sets of doors 13 on one side hinge. The middle of the door 13 is set as a glass window 131. The door 13 can be rotated and opened. The glass window 131 is set to facilitate observation of the painting process and fixed position of the steel inside the paint spraying box 1.
[0024] The transmission assembly 22 includes a horizontal frame 221 that is slidably connected to the sliding sleeve frame 23. The two ends of the horizontal frame 221 are rotatably connected to built-in transmission wheels 223. The motor component 26 is located on one side of a set of built-in transmission wheels 223. The motor component 26 drives the built-in transmission wheels 223 to rotate, thereby driving the transmission belt 222 to move and complete the conveying.
[0025] A transmission belt 222 is fitted to the outer side of the built-in transmission wheel 223. Two sets of lower gears 251 are sleeved on both sides of the rotating connecting rod 25. The lower gears 251 are engaged with the lower ends of the transmission belts 222. One set of transmission belts 222 drives the rotating connecting rod 25 to rotate through the lower gears 251. The rotating connecting rod 25 drives the other set of transmission belts 222 to rotate synchronously. The lower gears 251 can slide along the rotating connecting rod 25 to adjust their position. However, the lower gears 251 and the rotating connecting rod 25 rotate synchronously to realize the synchronous transmission of the two sets of transmission components 22.
[0026] The adjusting disc 24 includes a semi-threaded rod 241 threadedly connected to the lower end of the horizontal frame 221. The two ends of the semi-threaded rod 241 are positioned opposite to the threads of the two sets of transmission components 22. The two sets of adjusting discs 24 can be manually rotated, so that the two sets of semi-threaded rods 241 can drive the two sets of transmission components 22 to adjust their positions respectively.
[0027] Example 2: Combination Figure 5 The negative pressure fixing mechanism 3 includes a collection box 31 sleeved on the conveyor frame 21. The collection box 31 is set inside the box body 11. A support frame 32 is fixedly installed at the upper end of the collection box 31. A liftable lifting plate 33 is installed at the upper end of the support frame 32. A telescopic rod is connected to the lower end of the lifting plate 33. The telescopic rod is fixed at the lower end of the support frame 32. The lifting plate 33 assists in positioning the steel plate. The collection box 31 is used to receive excess paint.
[0028] Vacuum suction cups 331 are arranged around the lifting plate 33. One end of the vacuum suction cup 331 is pumped by a vacuum pump to create a negative pressure environment in the sealed space. The vacuum pump is located at the lower end of the lifting plate 33. The vacuum suction cups 331 fix the steel plate under negative pressure.
[0029] The painting robot 4 is fixedly mounted on the top of the housing 11. The painting robot 4 adopts a multi-joint design, which has high flexibility and repeatability. It can accurately position the spray gun to the part that needs to be sprayed. This is existing technology, so it will not be described in detail.
