Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically a high-protection spray booth system. Background Technology

[0002] In existing spraying operations, the spray booth system, as a core piece of equipment, directly impacts spraying quality and the working environment due to its airtightness and ease of operation. Current spray booths typically have open loading and unloading ports. Although mechanisms to absorb spray mist are included, a significant amount still escapes from the port. Some booths have closed doors at the port, which are only opened when loading or unloading is required, but even these still result in considerable spray mist escaping. Both approaches significantly pollute the working environment and negatively impact the health of operators. Therefore, there is an urgent need for a structurally optimized spray booth system with excellent airtightness to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a highly protective spray booth system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-protection spray booth system, comprising a spray booth body, a spraying turntable, a spraying robot, an air inlet system, an air outlet system, a sealing hood, and a window door; the spraying turntable is disposed inside the spray booth body, and the spraying turntable includes a rotary drive mechanism and multiple turntable plates connected to the output end of the rotary drive mechanism, wherein the turntable plates include a loading position, a spraying position, and a unloading position on the rotation trajectory; The spraying robot is suspended and installed. The air inlet system is located on the top of the spray booth body, and the air outlet system is located on one side of the spray booth body. The bottom of the spray booth body is connected to the air outlet system through a channel. The spray booth body has a loading window and a unloading window corresponding to the rotation position of the turntable plate. The window door is slidably disposed on the outside of the spray booth body to close the loading window or the unloading window. The sealing cover is slidably disposed on the inside of the spray booth body and above the turntable plate at the loading or unloading position. The sealing cover and the window door are connected by a linkage mechanism. When the window door moves upward to open, the linkage mechanism drives the sealing cover to move downward and cover the turntable plate at the loading or unloading position. When the window door moves downward to close, the linkage mechanism drives the sealing cover to move upward to reset, so that the sealing cover and the workpiece on the turntable plate are out of alignment.

[0005] Preferably, the linkage mechanism includes a first fixed pulley, a second fixed pulley, and a traction rope. The first fixed pulley and the second fixed pulley are respectively fixed on the inner and outer sides of the spray booth body. One end of the traction rope is fixedly connected to the enclosure, and the other end passes through the first fixed pulley and the second fixed pulley in sequence and is fixedly connected to the window door.

[0006] Preferably, the top of the window door is connected to the output end of the linear drive mechanism, which is fixedly installed on the outside of the spray booth body.

[0007] Preferably, the spray booth body is provided with guide rails corresponding to the movement paths of the window door and the enclosure, and the window door and the enclosure are respectively slidably engaged with their respective guide rails.

[0008] Preferably, the rotary drive mechanism is a servo motor, the linear drive mechanism is a cylinder, and the driving force of the cylinder plus the weight of the window door is greater than the weight of the enclosure, and the weight of the enclosure is greater than the weight of the window door.

[0012] Preferably, a limiting strip is fixedly installed on the outside of the spray booth body, and the limiting strip is located below the loading window and the unloading window.

[0013] Preferably, a buffer pad is fixedly provided on the upper surface of the limiting strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The spraying robot of this utility model adopts a hanging installation method, which eliminates the problem of traditional floor installation occupying bottom space, effectively expands the internal working space of the spray booth, improves the flexibility of equipment layout, and facilitates the adaptation to the spraying needs of workpieces of different sizes.

[0015] 2. The linkage mechanism between the window door and the enclosure of this utility model achieves synchronous response of loading and unloading operations and enclosure protection through the cooperation of fixed pulleys and traction ropes. When the operator controls the window door to move upward to carry out loading and unloading operations, the traction rope pulls the enclosure down precisely along the guide rail through the steering action of the fixed pulley group, and covers the turntable plate at the loading and unloading position, physically isolating the spraying area from the external operating space and preventing paint droplets from overflowing.

[0016] 3. The oil receiving frame of this utility model can receive paint dripping during the operation of the robot arm. The V-shaped filter paper can increase the interception area, initially filter out solid particles in the waste liquid, and reduce pollution to the bottom channel of the spray booth. The air outlet filter structure can adsorb volatile organic compounds and residual paint particles in the exhaust air. The air after double filtration is discharged from the air outlet, effectively reducing pollution to the surrounding environment. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4This utility model provides a technical solution: a high-protection spray booth system, including a spray booth body 1, a spraying turntable 2, a spraying robot 3, an air inlet system 4, an air outlet system 5, a closed cover 6, and a window door 10; the spraying turntable 2 is disposed inside the spray booth body 1, and the spraying turntable 2 includes a rotary drive mechanism 17 and multiple turntable plates 15 connected to the output end of the rotary drive mechanism 17. The turntable plates 15 include a loading position, a spraying position, and a unloading position on the rotation trajectory; The spraying robot 3 is installed by hanging. The air inlet system 4 is located on the top of the spray booth body 1, and the air outlet system 5 is located on one side of the spray booth body 1. The bottom of the spray booth body 1 is connected to the air outlet system 5 through the channel 7. The spray booth body 1 has a loading window 8 and a unloading window 9 at the rotation position of the turntable plate 15. The window door 10 is slidably set on the outside of the spray booth body 1 to close the loading window 8 or the unloading window 9. The sealing cover 6 is slidably set on the inside of the spray booth body 1 and is located above the turntable plate 15 at the loading or unloading position. The sealing cover 6 and the window door 10 are connected by a linkage mechanism 11. When the window door 10 moves upward to open, the linkage mechanism 11 drives the sealing cover 6 to move downward and cover the turntable plate 15 at the loading or unloading position. When the window door 10 moves downward to close, the linkage mechanism 11 drives the sealing cover 6 to move upward to reset, so that the sealing cover 6 and the workpiece on the turntable plate 15 are out of alignment.

[0021] It is understood that in this embodiment, both the loading window 8 and the unloading window 9 are provided with a closed cover 6 and a window door 10 connected by a linkage mechanism, and the closed cover 6 has an open opening on the side corresponding to the loading window 8 or the unloading window 9.

[0022] Combination Figure 4 As shown, the linkage mechanism 11 includes a first fixed pulley 12, a second fixed pulley 13 and a traction rope 14. The first fixed pulley 12 and the second fixed pulley 13 are fixed on the inner and outer sides of the spray booth body 1, respectively. One end of the traction rope 14 is fixedly connected to the enclosure 6, and the other end passes through the first fixed pulley 12 and the second fixed pulley 13 in sequence and is fixedly connected to the window door 10.

[0023] The vertical movement of the window door 10 is linked to the enclosure 6 via the traction rope 14. When the operator moves the window door 10 upward to open the loading window 8 or unloading window 9, the traction rope 14, guided by the first fixed pulley 12 and the second fixed pulley 13, synchronously pulls the enclosure 6 downward along the guide rail 16 on the inner wall of the spray booth body 1 until the enclosure 6 completely covers the workpiece on the turntable plate 15 at the loading or unloading position. At this time, the workpiece to be sprayed or already sprayed on the spraying turntable 2 is within the protection range of the enclosure 6, effectively preventing paint droplets generated during the spraying process from escaping through the opened window.

[0024] Combination Figure 4 As shown, the spray booth body 1 is equipped with guide rails 16 corresponding to the movement paths of the window door 10 and the enclosure 6. The window door 10 and the enclosure 6 slide in cooperation with their respective guide rails 16. The guide rails 16 ensure that the window door 10 and the enclosure 6 always maintain a straight trajectory during movement, avoiding problems such as poor sealing or jamming caused by deviation.

[0025] Combination Figure 1 As shown, in this embodiment, the rotary drive mechanism 17 is a servo motor, the linear drive mechanism 25 is a cylinder, and the driving force of the cylinder plus the weight of the window door 10 is greater than the weight of the enclosure 6. The weight of the enclosure 6 is greater than the weight of the window door 10.

[0026] Understandably, the weight of the enclosure 6 is only slightly greater than the weight of the window door 10, enough to allow the enclosure 6 to descend slowly and the window door 10 to rise slowly.

[0027] Combination Figure 1 As shown, the spraying robot 3 is suspended on the mounting frame 18, which is a frame structure fixedly installed inside the spray booth body 1.

[0028] Combination Figure 1 As shown, the bottom of the spraying robot 3 is equipped with an oil receiving frame 19, and a V-shaped filter paper 20 is installed inside the oil receiving frame 19. When the paint residue flows into the oil receiving frame 19, it will first pass through the V-shaped filter paper 20 for preliminary filtration, which will intercept solid particles or paint lumps that are not fully atomized. The filtered clear liquid will be deposited in the liquid collection tank at the bottom of the oil receiving frame 19, which can effectively avoid environmental pollution caused by waste liquid leakage.

[0029] Combination Figure 1 As shown, the exhaust system 5 is equipped with an exhaust filter structure 21, which is an activated carbon filter layer. An exhaust port 22 is provided at the top of the exhaust system 5. When the exhaust gas flows through the activated carbon filter layer of the exhaust filter structure 21, the porous structure of the activated carbon will fully adsorb the organic pollutants and residual paint mist molecules in the exhaust gas. The clean air after adsorption and purification is then discharged outdoors through the exhaust port 22, effectively reducing the impact of exhaust gas on the surrounding environment.

[0030] Combination Figure 4 As shown, a limiting strip 23 is fixedly installed on the outside of the spray booth body 1. The limiting strip 23 is located below the loading window 8 and the unloading window 9. A buffer pad 24 is fixedly installed on the upper surface of the limiting strip 23. When the window door 10 moves downward to close after completing the loading and unloading operation, its bottom edge will first contact the buffer pad 24 on the upper surface of the limiting strip 23. The elastic material of the buffer pad 24 can effectively reduce the impact force when the window door 10 falls, and avoid the metal window door 10 from directly colliding with the spray booth body 1 to cause wear or noise.

[0031] Working principle: When a loading operation is required, the operator cancels the driving force of the linear drive mechanism 25, causing the window door 10 at the loading window 8 to move upward. The window door 10 moves upward along the guide rail 16, and the traction rope 14 drives the enclosure 6 to move downward. The enclosure 6 descends smoothly and finally covers the turntable plate of the spraying turntable 2. At this time, the operator can place the workpiece to be sprayed on the turntable plate.

[0032] After the material is loaded, the operator controls the linear drive mechanism 25 to drive the window door 10 to move down, the window door 10 closes, the sealing cover 6 moves up and resets, and then the turntable plate 15 at the loading position can rotate to the spraying robot 3 to perform spraying operations on the workpiece. During the spraying process, the paint droplets are filtered and absorbed by the V-shaped filter paper 20, and the spray mist is purified by the exhaust filter structure 21 before being discharged.

[0033] After the workpiece is coated, the turntable plate 15 at the coating position rotates to the unloading position. The operator cancels the driving force of the linear drive mechanism 25, causing the window door 10 at the unloading window 9 to be pushed upward. Through the linkage mechanism 11, the sealing cover 6 is driven to descend and cover the turntable plate at the unloading position. The operator removes the coated workpiece from the turntable plate. After the unloading operation is completed, the window door 10 is reset, and the sealing cover 6 is also raised and reset, entering the next work cycle.
