Description

Technical Field

[0001] This invention relates to the field of spray coating technology for guide post processing, and more particularly to a spray coating equipment for processing sliding guide posts. Background Technology

[0002] Sliding guide pillars, as key guiding components in mechanical equipment, are widely used in molds, precision machine tools, and automation devices. Their surface quality directly affects the motion accuracy, service life, and stability of the equipment. Currently, the processing of sliding guide pillars typically involves multiple processes such as turning and grinding, and surface treatment technology is used in the final stage to improve their performance. Among these processes, spraying (or coating) is a commonly used technique to form a uniform protective or functional coating (such as anti-rust paint, wear-resistant layer, etc.) on the surface of the guide pillar. Existing spraying equipment mostly uses handheld or fixed spray guns, combined with a rotating worktable or conveyor mechanism, to make the guide pillar rotate at a uniform speed during the spraying process to ensure the integrity of the coating coverage. This type of equipment has a relatively simple structure and mainly uses compressed air to atomize the paint and spray it onto the workpiece surface. The spraying parameters, such as spraying distance, moving speed, and paint flow rate, are controlled by the operator's experience or preset programs.

[0003] In the existing process of spraying and coating sliding guide posts, the paint mist generated during spraying is not treated and collected in a timely manner, resulting in a large number of suspended paint mist particles permeating the working environment and eventually settling on the surface of the coated sliding guide posts. This phenomenon has multiple adverse effects on coating quality. First, the falling paint mist will form tiny particulate deposits on the cured or not fully dried paint layer, increasing surface roughness. This not only affects the smoothness of the appearance but may also damage the continuity and density of the coating, reducing its corrosion resistance and wear resistance. Second, the random settling of paint mist will lead to uneven coating thickness. Excessive thickness in some areas can easily cause defects such as sagging and orange peel, while insufficient thickness in some areas may fail to meet the preset protection requirements, thus affecting the sliding guide post's performance. Reliability under high-speed or heavy-load conditions is a concern. Furthermore, accumulated paint mist can embed itself between coatings, forming stress concentration points during subsequent curing, weakening the bond between the coating and the substrate, and easily leading to peeling and flaking after long-term use. Although some existing equipment attempts to improve the working environment by adding ventilation or simple filtration devices, these measures often focus on the health protection of operators rather than specifically addressing the secondary pollution of workpiece surfaces by paint mist. For example, while ordinary exhaust fans can partially remove suspended paint mist, they cannot achieve precise guidance and efficient separation, and may instead disrupt airflow, making the paint mist more likely to diffuse. Simple filters are prone to clogging, require frequent maintenance, and have limited capture efficiency, making them difficult to adapt to continuous production rhythms.

[0004] Therefore, how to provide a spraying equipment for processing sliding guide posts is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to provide a spraying equipment for processing sliding guide posts, and the present invention solves the problems mentioned in the background art.

[0006] According to an embodiment of the present invention, a spraying device for processing sliding guide pillars includes a processing box, a spray gun, a guide pillar body, and an opening / closing door. The opening / closing door is rotatably installed at an opening on one side of the processing box. A partition plate is horizontally fixedly installed inside the processing box near the bottom. A bottom clamping component is embedded in the partition plate. The bottom clamping component includes two sets of clamping rods, which are movably clamped at both ends of the guide pillar body. A translation component is fixedly installed inside the processing box near the top, located diagonally above the guide pillar body and parallel to it. An air extraction component is fixedly installed at the top of the translation component. An air hood adjustment component is installed at the bottom of the translation component. Two symmetrically arranged air hood bodies are rotatably connected to one side of the air hood adjustment component. A support arm is fixedly installed at the bottom of the translation component between the two air hood bodies. The spray gun is fixedly installed at the other end of the support arm, located directly above the guide pillar body. The two air hood bodies are axially symmetrical about the spray gun. The other end of the air extraction component is fixedly connected to and communicates with the opposite side of the two air hood bodies.

[0007] The bottom clamping component also includes a sliding cavity, a fixed support plate, a movable support plate, a first synchronous pulley, a first synchronous belt, a drive motor, a rotating gear shaft, and transmission gears. The sliding cavity is embedded in the top of the partition plate, and the fixed support plate is fixedly installed inside the sliding cavity near one end. The movable support plate is slidably connected inside the sliding cavity. Two sets of clamping rods are rotatably connected to the opposite surfaces of the movable and fixed support plates, respectively. The opposing ends of the two sets of clamping rods pass through the movable and fixed support plates and extend to their opposing surfaces. There are two sets of first synchronous pulleys, one in each set. The first synchronous pulley is fixedly installed at the opposite ends of the two sets of clamping rods. The other set of first synchronous pulleys is rotatably installed on the opposite surfaces of the fixed support plate and the movable support plate, near the bottom. The transmission gear is fixedly installed on the surface of the first synchronous pulley located at the bottom of the fixed support plate and the movable support plate. The first synchronous belt is movably sleeved on the surface of the two sets of first synchronous pulleys. The rotating gear shaft is rotatably connected to both sides of the inner wall of the sliding cavity and is parallel to the guide column body. The transmission gear meshes with the rotating gear shaft. One end of the rotating gear shaft passes through the sliding cavity and is fixedly connected to the output shaft of the drive motor. The drive motor is fixedly installed on the side of the sliding cavity.

[0008] The bottom clamp also includes an adjusting screw, a protective cover, and a telescopic guard plate. One end of the adjusting screw is rotatably mounted on the fixed support plate near the movable support plate, and the other end of the adjusting screw passes through the movable support plate and extends to the side of the movable support plate away from the fixed support plate. The adjusting screw is located directly above the transmission gear. Both ends of the telescopic guard plate are fixedly connected to the opposite surfaces of the fixed support plate and the movable support plate above the adjusting screw. The protective cover is fixedly mounted on the opposite surfaces of the movable support plate and the fixed support plate, and the protective cover movably covers the surfaces of the first synchronous pulley and the first synchronous belt.

[0009] The translation assembly includes a guide rail, a movable block, and a reciprocating lead screw. The guide rail is fixedly installed on both sides of the inner wall of the machining box, located obliquely above the guide column body. The reciprocating lead screw is rotatably installed inside the machining box at the position opposite to the guide rail. The movable block is movably connected inside the guide rail and is movably sleeved on the surface of the reciprocating lead screw.

[0010] A synchronous shaft is fixedly installed at the end of the rotating gear shaft away from the drive motor. The other end of the synchronous shaft passes through the sliding cavity and the machining box and extends to the outside of the machining box. One end of the reciprocating lead screw passes through the machining box and extends to the outside of the machining box. A second synchronous pulley is fixedly installed at the end of the reciprocating lead screw and the synchronous shaft located outside the machining box. A second synchronous belt is movably sleeved on the surface of the second synchronous pulley.

[0011] The air extraction assembly includes a negative pressure fan, a central box, and two sets of flexible central pipes. The central box is fixedly installed on the top of the movable block by a fixing frame. The negative pressure fan is fixedly installed on the top of the central box. The opposite sides of the two sets of flexible central pipes are fixedly connected to and communicate with the two sides of the central box. The other ends of the two sets of flexible central pipes are fixedly connected to and communicate with the opposite sides of the two sets of air hood bodies, respectively.

[0012] The flexible central tube is connected to the air hood body at one end, which is a three-part tube. The three parts are evenly distributed on the side of the air hood body near the guide column body. The air hood body has a "conical" shrinking design. The opening of the air hood body is larger when it is close to the spray gun, and the opening becomes smaller when it is further away from the spray gun.

[0013] The air extraction assembly also includes an outer sealing plate, a retaining ring, a rubber sealing ring, and a filter element. The filter element is fixedly installed inside the outer sealing plate and is movably installed inside the collection box in a pull-out manner, located above the two sets of flexible collection pipes communicating with the collection box. The outer sealing plate is in contact with the opening of the collection box. The retaining ring is fixedly installed on the side of the outer sealing plate, and the rubber sealing ring is fixedly installed on the side of the collection box corresponding to the position of the retaining ring. The retaining ring is movably engaged with the surface of the rubber sealing ring, and the negative pressure fan is located above the filter element.

[0014] The extraction assembly also includes a clutch-type transmission component, which comprises a rack, a mounting bracket, a guide shaft, a rotating gear, a wedge-shaped block annular turntable, a wedge-shaped groove annular turntable, a spring, and a guide groove. The rack is fixedly mounted on the top of the inner wall of the processing box, the mounting bracket is fixedly mounted on the top of the collection box, the guide shaft is longitudinally slidably connected to the mounting bracket, and the guide shaft is located directly above the negative pressure fan. A protruding guide block is fixedly connected to the inner wall of the wedge-shaped block annular turntable. The wedge-shaped block annular turntable is movably sleeved on the surface of the guide shaft through the guide block, and the guide block is slidably connected inside the guide groove. Fixedly installed on the rotating shaft of the negative pressure fan, the spring is movably sleeved on the surface of the guide shaft between the mounting bracket and the wedge-shaped block annular turntable. Under the action of the spring force, the wedge-shaped block annular turntable and the wedge-shaped groove annular turntable are meshed together. The rotating gear is fixedly installed on the top of the guide shaft and meshes with the rack. The guide groove is opened on the surface of the guide shaft. When the wedge-shaped block annular turntable rotates forward, the wedge-shaped groove annular turntable rotates synchronously. When the wedge-shaped block annular turntable rotates in the reverse direction, the wedge-shaped groove annular turntable squeezes the wedge-shaped block annular turntable and pushes the spring upward to separate the wedge-shaped block annular turntable from the wedge-shaped groove annular turntable.

[0015] The air hood adjustment component includes a longitudinal screw, a sleeve, a drive shaft, a mounting plate, a rotating swing arm, and an adjustment knob. The longitudinal screw is fixedly installed at the bottom of the movable block. The drive shaft is fixedly installed on the opposite side of the two sets of air hood bodies near the longitudinal screw. The other end of the drive shaft extends to the position of the longitudinal screw, and the sleeve is rotatably fitted onto the surface of the drive shaft. The sleeve is movably fitted onto the surface of the longitudinal screw. The mounting plate is fixedly installed at the bottom of the movable block. The top end of the rotating swing arm is rotatably connected to one end of the mounting plate, and the bottom end of the rotating swing arm is rotatably connected to the side of the air hood body. The adjustment knob is rotatably installed at the bottom of the sleeve and threaded onto the surface of the longitudinal screw.

[0016] The beneficial effects of this invention are: The bottom clamp of this invention integrates a mechanism for moving a movable support plate by adjusting a screw, making the clamping and centering adjustment of the guide post simpler and more precise. Combined with a protective cover to protect the transmission components, it enhances clamping stability, operational safety, and equipment durability. By synchronously rotating two sets of clamping rods in the bottom clamp to drive the guide post body, synchronous and stable rotation of both ends of the guide post is achieved, effectively avoiding the rotational eccentricity problem caused by single-end drive. This significantly improves the uniformity of the sprayed coating thickness and overall precision, ensuring workpiece quality.

[0017] By setting up an air extraction component linked to the spray gun and a specially shaped air hood body, a directional negative pressure airflow can be formed near the spraying point to collect the paint mist generated during spraying in a timely and efficient manner, preventing it from drifting and settling on the processed surface. This solves the problem of secondary pollution of the coating surface by paint mist from the source, and improves the appearance and performance of the product.

[0018] By using a synchronous shaft, synchronous pulley, and synchronous belt to mechanically link the rotation drive of the guide column with the translation drive of the spray gun, the automatic synchronization of the reciprocating movement of the spray gun and the rotational movement of the workpiece is achieved. This simplifies the equipment structure, reduces the complexity and cost of an independent control system, and ensures the stability and consistency of the spraying path.

[0019] The extraction assembly innovatively employs a clutch-type transmission component driven by translational motion, which allows the negative pressure fan to operate only when the spray gun is performing the plating operation, and automatically separate and stop on the return stroke. This achieves adaptive start and stop of negative pressure extraction, which is both energy-saving and avoids reverse airflow interference, demonstrating a high degree of intelligence.

[0020] By setting up an air hood adjustment component, the opening angle and direction of the air hood bodies on both sides can be easily adjusted, so that it can be aligned with the spray gun point for concentrated collection, and the coverage area can be expanded to cope with large paint mist conditions. This enhances the equipment's adaptability to different spraying process parameters and improves the reliability and flexibility of paint mist collection.

[0021] The filter element inside the central box adopts a composite structure of metal mesh and filter cotton, and is designed as a pull-out type. Combined with a quick-sealing and disassembly structure consisting of a retaining ring and a rubber sealing ring, the maintenance, cleaning or replacement of the filter components becomes simple and quick, effectively ensuring the continuous and efficient operation of the filtration system and reducing equipment maintenance downtime.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0035] Example 1 refer to Figure 1-11 In this embodiment, the system includes a processing housing 1, a spray gun 2, a guide post body 3, and an opening / closing door 4. The opening / closing door 4 is rotatably installed at an opening on one side of the processing housing 1. A partition plate 5 is horizontally and fixedly installed inside the processing housing 1 near the bottom. The partition plate 5 partially separates the bottom clamping component 6, reducing its impact on the work area. The bottom clamping component 6 is embedded in the partition plate 5 and is used to clamp the guide post body 3. Figure 2 As shown, the guide post body 3 is cylindrical and is clamped by the bottom clamping component 6. The bottom clamping component 6 includes two sets of clamping rods 7, which are movably clamped at both ends of the guide post body 3. During clamping, it is necessary to adjust the clamping positions at both ends of the guide post body 3 as much as possible so that the opposing surfaces of the two sets of clamping rods 7 are as close as possible to the axis of the guide post body 3. This avoids the problem of excessive eccentricity during later rotation, because eccentricity will affect the thickness and accuracy of the spraying. Therefore, the clamping process is very important. Specifically, the bottom clamping component 6 also includes a sliding cavity 13, a fixed support plate 14, a movable support plate 15, a first synchronous pulley 16, a first synchronous belt 17, a drive motor 18, a rotating gear shaft 19, and a transmission gear 20. The sliding cavity 13 is embedded in the top of the partition plate 5, as shown. Figure 2 and Figure 4As shown, the sliding cavity 13 is built into the partition plate 5, and its top surface is in the same plane as the surface of the partition plate 5. The fixed support plate 14 is fixedly installed inside the sliding cavity 13 near one end. The fixed support plate 14 is fixed and not easy to move. The movable support plate 15 is slidably connected inside the sliding cavity 13. During the clamping operation, the movable support plate 15 can be moved. The two sets of clamping rods 7 are rotatably connected to the opposite surfaces of the movable support plate 15 and the fixed support plate 14, respectively. The opposite ends of the two sets of clamping rods 7 pass through the movable support plate 15 and the fixed support plate 14 and extend to the opposite surfaces of the movable support plate 15 and the fixed support plate 14, respectively. There are two sets of first synchronous pulleys 16. One set of first synchronous pulleys 16 is fixedly installed on the opposite ends of the two sets of clamping rods 7, and the other set of first synchronous pulleys 16 is rotatably installed on the opposite surfaces of the fixed support plate 14 and the movable support plate 15 near the bottom. At the designated position, the transmission gear 20 is fixedly installed on the surface of the first synchronous pulley 16 located at the bottom of the fixed support plate 14 and the movable support plate 15. The first synchronous belt 17 is movably sleeved on the surfaces of the two sets of first synchronous pulleys 16. The rotating gear shaft 19 is rotatably connected to both sides of the inner wall of the sliding cavity 13 and is parallel to the guide column body 3. The rotating gear shaft 19 is in the shape of a long rod with a gear-shaped interface. The transmission gear 20 is meshed with the rotating gear shaft 19. No matter how the movable support plate 15 moves the transmission gear 20 at this position, it will still mesh with the rotating gear shaft 19. One end of the rotating gear shaft 19 passes through the sliding cavity 13 and is fixedly connected to the output shaft of the drive motor 18. The drive motor 18 is fixedly installed on the side of the sliding cavity 13. The components on the fixed support plate 14 and the movable support plate 15 are the same. Here, the drive motor 18 is a reduction drive motor 18, which drives the rotating gear shaft 19 to rotate.

[0036] In practice, the rotating gear shaft 19 rotates, driving two sets of transmission gears 20 to rotate synchronously. The synchronous rotation of the two sets of transmission gears 20 drives two sets of clamping rods 7 to rotate synchronously via the first synchronous wheel 16 and the first synchronous belt 17. The synchronous rotation of the two sets of clamping rods 7 drives the clamped guide post body 3 to rotate. This synchronous rotation is more stable than the existing technology of rotating on one side with three-point clamping at one end. Moreover, it is not easy to shake during rotation and is very stable. The synchronous rotation of the clamped ends improves the rotational stability of the guide post body 3.

[0037] The bottom clamp 6 also includes an adjusting screw 21, a protective cover 22, and a telescopic guard plate 23. One end of the adjusting screw 21 is rotatably mounted on the fixed support plate 14 near the movable support plate 15. The other end of the adjusting screw 21 passes through the movable support plate 15 and extends to the side of the movable support plate 15 away from the fixed support plate 14. The adjusting screw 21 is located directly above the transmission gear 20. Both ends of the telescopic guard plate 23 are fixedly connected to the opposite surfaces of the fixed support plate 14 and the movable support plate 15 above the adjusting screw 21. The protective cover 22 is fixedly mounted on the opposite surfaces of the movable support plate 15 and the fixed support plate 14. The protective cover 22 movably covers the surfaces of the first synchronous pulley 16 and the first synchronous belt 17.

[0038] In practice, the adjusting screw 21 is rotated. The movable support plate 15 is threaded onto the surface of the adjusting screw 21, with only one end rotatably connected to the fixed support plate 14. During the rotation of the adjusting screw 21, the movable support plate 15 will move closer to the fixed support plate 14, thereby bringing the two sets of clamping rods 7 closer to each other. Then, the guide post body 3 is placed between the two sets of clamping rods 7. The two ends of the guide post body 3 are marked with the axis points in advance. When clamping, the two sets of clamping rods 7 can fall on the marks. After the clamping is stable, the drive motor 18 is started.

[0039] Example 2 refer to Figure 1-11 In this embodiment, a translation component 8 is fixedly installed near the top of the processing box 1, located obliquely above and parallel to the guide post body 3. The translation component 8 includes a guide rail 24, a movable block 25, and a reciprocating screw 26. The guide rail 24 is fixedly installed on both sides of the inner wall of the processing box 1, located obliquely above the guide post body 3. Two sets of guide rails 24 are provided to limit and guide the movable block 25. The reciprocating screw 26 is rotatably installed inside the processing box 1 at the position opposite to the guide rail 24. The movable block 25 is movably connected inside the guide rail 24 and is movably sleeved on the surface of the reciprocating screw 26. The reciprocating screw 26 is selected and used according to the actual spraying speed and movement mode. The rotation of the reciprocating screw 26 will drive the movable block 25 to move back and forth on the surface of the reciprocating screw 26.

[0040] In practice, the rotation of the reciprocating screw 26 will drive the movable block 25 to move along the guide rail 24. This movement is a straight line and parallel to the guide post body 3, thereby ensuring that the distance between the spray gun 2 and the guide post body 3 is constant and ensuring the spraying quality.

[0041] Example 3 refer to Figure 1-11In this embodiment, an exhaust assembly 9 is fixedly installed on the top of the translation assembly 8. The exhaust assembly 9 includes a negative pressure fan 30, a collection box 31, and two sets of flexible collection pipes 32. The collection box 31 is a component that concentrates two parts of gas together. The collection box 31 is fixedly installed on the top of the movable block 25 by a fixing bracket. The negative pressure fan 30 is fixedly installed on the top of the collection box 31. Here, the negative pressure fan 30 is located on the top of the collection box 31 and generates negative pressure by rotating. The opposite surfaces of the two sets of flexible collection pipes 32 are fixedly connected to and communicate with the two sides of the collection box 31. The other ends of the two sets of flexible collection pipes 32 are fixedly connected to and communicate with the opposite surfaces of the two sets of air hood bodies 11, respectively.

[0042] In practice, the movement of movable block 25 will also cause the air extraction component 9 to move synchronously, such as... Figure 2 and Figure 7 As shown, the two sets of flexible central pipes 32 are used to realize the air guiding function. When the negative pressure fan 30 generates negative pressure, the gas enters from the position of the air cover body 11 and reaches the collection box through the two sets of flexible central pipes 32.

[0043] The flexible central tube 32 is connected to the air cover body 11 at one end, which is a three-part tube. The three-part tubes are evenly distributed on the side of the air cover body 11 near the guide column body 3. The air cover body 11 has a "conical" shrinking design. The opening of the air cover body 11 is larger when it is close to the spray gun 2, and the opening of the air cover body 11 becomes smaller when it is further away from the spray gun 2.

[0044] In practice, the three-part pipe increases the range and area of ​​air intake, which can draw in more paint mist in the air. The "conical" contraction design of the air hood body 11 improves the concentration of gas and facilitates the rapid intake of gas into the flexible concentrator 32.

[0045] Example 4 refer to Figure 1-11 In this embodiment, the air extraction assembly 9 also includes an outer sealing plate 33, a retaining ring 34, a rubber sealing ring 35, and a filter element 36. The filter element 36 is a combination of metal mesh and filter cotton. The filter element 36 is fixedly installed inside the outer sealing plate 33. The filter element 36 is movably installed in a pull-out manner inside the collection box 31 and is located above the two sets of flexible collection pipes 32 communicating with the collection box 31. The outer sealing plate 33 is in contact with the opening of the collection box. The retaining ring 34 is fixedly installed on the side of the outer sealing plate 33. The rubber sealing ring 35 is fixedly installed on the side of the collection box 31 corresponding to the position of the retaining ring 34. The retaining ring 34 is an annular sleeve that fits into the opening of the collection box 31. Its inner wall has a mating groove that matches the shape of the rubber sealing ring 35. The retaining ring 34 is movably engaged with the surface of the rubber sealing ring 35. The negative pressure fan 30 is located above the filter element 36.

[0046] In the specific implementation, a filter element 36 is added here to filter the concentrated gas. The filtered gas is discharged through the negative pressure fan 30. The top of the processing box 1 has an air outlet on the travel path of the negative pressure fan 30 to discharge the filtered gas. The design of the outer sealing plate 33, the retaining ring 34 and the rubber sealing ring is to provide a seal while also facilitating the disassembly and replacement of the filter element 36.

[0047] Example 5 refer to Figure 1-11 In this embodiment, a synchronous shaft 27 is fixedly installed at the end of the rotating gear shaft 19 away from the drive motor 18. The main function of the synchronous shaft 27 is synchronous transmission. The other end of the synchronous shaft 27 passes through the sliding cavity 13 and the processing box 1 and extends to the outside of the processing box 1. One end of the reciprocating screw 26 passes through the processing box 1 and extends to the outside of the processing box 1. A second synchronous pulley 28 is fixedly installed at the end of the reciprocating screw 26 and the synchronous shaft 27 located outside the processing box 1. A second synchronous belt 29 is movably sleeved on the surface of the second synchronous pulley 28. The power of the synchronous shaft 27 is transmitted to the second synchronous pulley 28, and then the second synchronous pulley 28 is driven to rotate through the second synchronous belt 29, thereby driving the reciprocating screw 26 to rotate without the need for additional power.

[0048] In practice, the rotation of the rotating gear shaft 19 will drive the synchronous shaft 27 to rotate. The synchronous shaft 27 will then transmit power to the reciprocating screw 26 through the second synchronous pulley 28 and the second synchronous belt 29. The reciprocating screw 26 can be stably driven to rotate by adjusting the transmission ratio of the second synchronous pulley 28, without the need for additional power.

[0049] Example 6 refer to Figure 1-11In this embodiment, the air extraction assembly 9 further includes a clutch-type transmission component 37, which includes a rack 38, a mounting bracket 39, a guide shaft 40, a rotating gear 41, a wedge-shaped block annular turntable 42, a wedge-shaped groove annular turntable 43, a spring 44, and a guide groove 45. The rack 38 is fixedly installed on the top of the inner wall of the processing box 1, and the rack 38 is also arranged parallel to the guide column body 3. The mounting bracket 39 is fixedly installed on the top of the collection box 31. The mounting bracket 39 positions and supports the guide shaft 40 at a certain height, so that the wedge-shaped block annular turntable 42 can move up and down on the surface of the guide column. The guide shaft 40 is longitudinally slidably connected to the mounting bracket 39. The guide shaft 40 is located directly above the negative pressure fan 30. A protruding guide block is fixedly connected to the inner wall of the wedge-shaped block annular turntable 42. The wedge-shaped block annular turntable 42 is movably sleeved on the surface of the guide shaft 40 through the guide block, and the guide block is slidably connected to the guide groove. Inside 45, the wedge-shaped annular turntable 42 is limited. When the guide shaft 40 rotates, it also drives the wedge-shaped annular turntable 42 to rotate. The wedge-shaped groove annular turntable 43 is fixedly installed on the rotating shaft of the negative pressure fan 30. The spring 44 is movably sleeved on the surface of the guide shaft 40 between the mounting bracket 39 and the wedge-shaped annular turntable 42. Under the elastic force of the spring 44, the wedge-shaped annular turntable 42 and the wedge-shaped groove annular turntable 43 are meshed together. The rotating gear 41 is fixedly installed at the top of the guide shaft 40. The rotating gear 41 meshes with the rack 38. The guide groove 45 is opened on the surface of the guide shaft 40. When the wedge-shaped annular turntable 42 rotates forward, the wedge-shaped groove annular turntable 43 rotates synchronously. When the wedge-shaped annular turntable 42 rotates in the opposite direction, the wedge-shaped groove annular turntable 43 squeezes the wedge-shaped annular turntable 42 and pushes the spring 44 upward to separate the wedge-shaped annular turntable 42 from the wedge-shaped groove annular turntable 43.

[0050] In practice, as the entire extraction assembly 9 moves, the rack 38 drives the rotating gear 41 to rotate. The rotation of the rotating gear 41 drives the guide shaft 40 to rotate, which in turn drives the wedge-shaped block annular turntable 42 to rotate. The wedge-shaped block annular turntable 42 rotates in the forward direction, and the spray gun 2 performs the spraying operation. During the movement, the forward rotation of the wedge-shaped block annular turntable 42 drives the wedge-shaped groove annular turntable 43 to rotate. The rotation of the wedge-shaped groove annular turntable 43 drives the rotating shaft on the negative pressure fan 30 to rotate, thereby driving the fan blades to rotate and generate negative pressure. The negative pressure fan 30 here does not have an electric drive source, unlike the existing electrically controlled negative pressure fan 30. It does not require the use of negative pressure circuit control. As long as the spray gun 2 is working, it will drive the negative pressure fan 30 to work. After the spraying is completed, the spraying... During the process of gun 2 returning to its original position, the movable block 25 will drive the suction assembly 9 to move in the opposite direction. During the reverse movement, the rotating gear 41 rotates in the opposite direction through the rack 38. The reverse rotation of the rotating gear 41 drives the wedge block annular turntable 42 to rotate in the opposite direction through the guide shaft 40. The wedge block annular turntable 42 is squeezed upward by the wedge groove annular turntable 43. The wedge block annular turntable 42 is squeezed and moves upward along the guide shaft 40 and squeezes the spring 44. At this time, the upward movement of the wedge block annular turntable 42 will separate from the wedge groove annular turntable 43, thus separating the power during the reverse movement. After separation, the wedge block annular turntable 42 and the wedge groove annular turntable 43 will not drive the negative pressure fan 30 to rotate, thus avoiding the negative pressure fan 30 from rotating in the opposite direction and pushing the gas in the opposite direction.

[0051] Example 7 refer to Figure 1-11In this embodiment, an air hood adjusting component 10 is installed at the bottom of the translation component 8. Two sets of air hood bodies 11 are symmetrically arranged and rotatably connected to one side of the air hood adjusting component 10. A support arm 12 is fixedly installed at the bottom of the translation component 8 between the two sets of air hood bodies 11. The spray gun 2 is fixedly installed at the other end of the support arm 12, located directly above the guide column body 3. The two sets of air hood bodies 11 are axially symmetrical about the spray gun 2. The other end of the air extraction component 9 is fixedly connected to and communicates with the opposite surfaces of the two sets of air hood bodies 11. The air hood adjusting component 10 includes a longitudinal screw 46, a sleeve 47, a drive shaft 48, a mounting plate 49, a rotating swing arm 50, and an adjusting knob 51. The longitudinal screw 46 is fixedly installed at the bottom of the movable block 25. The drive shaft 48 is fixedly installed on the opposite side of the two sets of air cover bodies 11 near the longitudinal screw 46. The other end of the drive shaft 48 extends to the position of the longitudinal screw 46, and the sleeve 47 is rotatably sleeved on the surface of the drive shaft 48. The sleeve 47 is movably sleeved on the surface of the longitudinal screw 46. The mounting plate 49 is fixedly installed at the bottom of the movable block 25. The top end of the rotating swing arm 50 is rotatably connected to one end of the mounting plate 49, and the bottom end of the rotating swing arm 50 is rotatably connected to the side of the air cover body 11. The adjustment knob 51 is rotatably installed at the bottom of the sleeve 47 and threadedly sleeved on the surface of the longitudinal screw 46.

[0052] In practice, when the spraying volume of the spray gun 2 increases or the moving speed is fast, the generated paint mist may not be completely processed before the air hood body 11 moves away. To address this, an air hood adjustment component 10 is used to adjust the state of the air hood. The bottom of the air hood body 11 has a gate-shaped through slot, which widens the range of the air hood body 11 and improves the paint mist collection capacity. During adjustment, the adjustment knob 51 is rotated first. Rotating the adjustment knob 51 will cause the sleeve block 47 to move downward along the longitudinal screw 46. The movement of the sleeve block 47 will cause the drive shaft 48 to move downward. The downward movement of the drive shaft 48 will drive the two sets of symmetrical air hood bodies. The top of 11 moves downward and rotates around the connection with the bottom of the rotating swing arm 50. While rotating, the bottom of the rotating swing arm 50 is spread out into a figure-eight shape. At this time, the openings of the two air shield bodies 11 rotate from the direction facing the spray gun 2 to the direction facing the guide column body 3. Continuous movement can change the opening state of the air shield body 11, thereby increasing the area covered by the air shield body 11 on the surface of the guide column body 3. The opening of the air shield body 11 is changed according to the amount of spraying and the moving speed of the spray gun 2. In this way, the air shield body 11 facing the guide column body 3 will collect a large area of ​​paint mist and avoid overflowing the air shield body 11.

[0053] The working principle of this invention is: During operation, the guide post body 3 is first placed between the two sets of clamping rods 7 of the bottom clamping component 6. The adjusting screw 21 is rotated to drive the movable support plate 15 to move, so that the clamping rods 7 are precisely clamped at the pre-marked axial positions at both ends of the guide post. The drive motor 18 is started, and the drive motor 18 drives the rotating gear shaft 19 to rotate. Through the two sets of transmission gears 20 meshing with it and the transmission mechanism consisting of the first synchronous pulley 16 and the first synchronous belt 17, the two sets of clamping rods 7 and the clamped guide post body 3 are driven to rotate at a uniform speed. At the same time, the power of the rotating gear shaft 19 is transmitted to the reciprocating screw 26 through the synchronous shaft 27, the second synchronous pulley 28 and the second synchronous belt 29, which drives the translation component 8, which is equipped with the movable block 25, to make reciprocating linear motion along the guide rail 24. The spray gun 2, which is fixed to the bottom of the movable block 25, moves accordingly and sprays the surface of the rotating guide post body 3. As the movable block 25 moves, its top suction assembly 9 moves synchronously. The translational motion is converted into the rotational motion of the guide shaft 40 through the meshing of the rack 38 and the rotating gear 41. When the spray gun 2 moves forward for spraying, the guide shaft 40 drives the rotating shaft of the negative pressure fan 30 to rotate through the meshing of the wedge-shaped block annular disc 42 and the wedge-shaped groove annular disc 43, generating negative pressure. This negative pressure is transmitted through the collection box 31 and the flexible collection pipe 32 to the air hood body 11 symmetrically arranged on both sides of the spray gun 2, efficiently drawing in the paint mist generated during spraying. The drawn-in paint mist-containing air is filtered by the easily removable filter element 36 inside the collection box 31 before being... The negative pressure fan 30 discharges the air. To adapt to different spraying conditions, the adjustment knob 51 on the air hood adjustment component 10 can be rotated. Through the linkage of the sleeve block 47, the drive shaft 48 and the rotating swing arm 50, the opening angle and opening direction of the two sets of air hood bodies 11 can be changed to optimize the paint mist collection range. When the spraying ends and returns, the wedge block annular turntable 42 in the clutch transmission component 37 is lifted and separated from the wedge groove annular turntable 43 in the reverse rotation. The negative pressure fan 30 automatically stops. Throughout the process, the stable rotation of the guide column, the synchronous movement of the spray gun 2 and the directional collection and filtration of paint mist work together to achieve high-quality and high-cleanliness spraying operation.
