Description

Technical Field

[0001] The invention belongs to the technical field of hardware processing, in particular to an automatic spraying device for hardware workpieces. Background Art

[0002] Hardware refers to tools made by processing and casting metals such as gold, silver, copper, iron, and tin. They are used to fix things, process things, and decorate. In order to ensure the service life of the hardware, it is often necessary to spray paint on the hardware to protect it.

[0003] The prior art also proposes some solutions. For example, a patent application with publication number CN116603668A discloses a rotary spraying device for hardware. The steering assembly drives the spray gun to continuously change its position. Combined with the rotation of the hardware, the raw materials can be more comprehensively covered on the surface of the hardware. In addition, with this structure, it is only necessary to continuously fix the hardware on the fixed arm outside the spray box. After the hardware enters the spray box and is sprayed, the sprayed hardware will be taken out of the spray box again by the conveyor belt, realizing the function of batch spraying of hardware and greatly improving production efficiency.

[0004] When the prior art uses a mechanical claw to clamp a tubular hardware workpiece, the mechanical claw itself will block a portion of the hardware workpiece, resulting in part of the surface of the hardware workpiece being unable to be sprayed with paint during the spraying process, requiring re-spraying later, thereby increasing the production process and reducing production efficiency.

[0005] To this end, the present invention provides a hardware workpiece automatic spraying device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: an automatic spraying equipment for hardware workpieces described in the present invention comprises a base; a pair of moving seats are slidably connected to the top surface of the base, and the moving seats are driven by a servo motor; a rotating rod is rotatably connected between the two moving seats; a plurality of evenly arranged mounting seats are fixedly connected to the surface of the rotating rod; a fixed column is rotatably connected to one end of the mounting seat away from the rotating rod; the fixed column is arranged in a hollow structure, and the fixed column is driven by a servo motor; a plurality of evenly arranged pressure rods are slidably connected to the side surface of the fixed column; the fixed column is connected to an external hydraulic control system through a hydraulic rotating joint; a conveying assembly is installed on one side of the base; the conveying assembly is used to deliver the tubular hardware workpiece to be sprayed to one side of the moving seat; a connecting frame is fixedly connected to the side of the base close to the conveying assembly; a plurality of evenly arranged spray guns are installed on the top of the connecting frame; when working, When spraying a piece, the embodiment of the present invention can be used. First, the hardware workpiece to be sprayed will be transported to the base by the conveying component, and then the tubular hardware workpiece will be sleeved on the outside of the fixed column. Then, the external hydraulic control system will introduce hydraulic oil into the inside of the fixed column, so that the pressure rod will be pressed against the inner surface of the tubular hardware workpiece, thereby fixing the tubular hardware workpiece. Then, the spray gun at the connecting frame will spray paint toward the surface of the tubular hardware workpiece at the fixed column. During the spraying process, the fixed column at the end face of the mounting seat will also rotate under the drive of the servo motor, thereby driving the tubular hardware workpiece to rotate together, so that the paint is sprayed more evenly. Since the tubular hardware workpiece is fixed from the inside by the fixed column and the pressure rod, the outside of the tubular hardware workpiece will not be blocked by the clamping component. Then, the fixed column is used to drive the tubular hardware workpiece to rotate, so that the surface of the workpiece can be evenly coated with paint without the need for secondary or multiple spraying, thereby improving work efficiency.

[0008] Preferably, the pressure rod is arranged in a hollow structure; the end of the pressure rod away from the fixed column is slidably connected with a push rod; the end of the push rod away from the pressure rod is fixedly connected with a rubber pad; the surface of the rubber pad is engraved with anti-skid patterns; during operation, when the hydraulic oil passes into the fixed column, the push rod will be pushed to extend out of the pressure rod, and the push rod will then push the rubber pad to press the rubber pad against the inner wall of the tubular hardware workpiece, thereby completing the fixation of the tubular hardware workpiece. Through the cooperation of the push rod and the pressure rod, the diameter of the tubular hardware workpiece that can be fixed by the push rod and the pressure rod is further expanded. At the same time, the rubber pad and the anti-skid patterns on its surface can also increase the maximum static friction between it and the inner wall of the tubular hardware workpiece, thereby preventing the tubular hardware workpiece from falling off when the fixed column drives the tubular hardware workpiece to rotate.

[0009] Preferably, the conveying assembly includes a support frame; a pair of support plates are installed on the top surface of the support frame; a plurality of evenly arranged partitions are fixedly connected to the top surface of the support plate, and the top surface of the partition is inclined; the fixed column corresponds to the gap between the paired partitions; a connecting plate is installed between the two support plates on the top surface of the support frame, and the support plate and the connecting plate are slidably connected; a hydraulic rod is provided on the bottom surface of the connecting plate; a plurality of evenly arranged push plates are slidably connected to the top surface of the connecting plate, and the bottoms of the push plates are fixed together; the telescopic end of the hydraulic rod is connected to the push plate The top surface of the push plate is arranged tilted, and the push plate is between the paired partitions. When the user needs to transport the tubular hardware workpiece to be sprayed, the conveyor belt can first place the tubular hardware workpiece between the partitions away from one end of the base, that is, both ends of the tubular hardware workpiece are between the paired partitions, and then the hydraulic rod is started to push the push plate up. Since the top of the push plate is arranged tilted, and the top of the partition is also arranged tilted, the push plate will push the tubular hardware workpiece between the paired partitions to the top of the next partition, and then the hydraulic rod drives the push plate to reset. The tubular hardware workpiece on the top of the partition will slide to the next pair of partitions along the inclined surface of the top of the partition, and then repeat the steps again. The tubular hardware workpiece will be moved between the paired partitions near the base, and then the rotating rod drives the mounting seat and the fixed column to rotate 90 degrees toward the top surface of the base, so that the fixed column is flush with the top surface of the base, and then the moving seat drives the rotating rod, the mounting seat and the fixed column to move toward the direction of the support frame, so that the fixed column is inserted into the tubular hardware workpiece to be sprayed, and then the tubular hardware workpiece is fixed by the pressure rod, the ejector rod and the rubber pad. The moving seat then drives the fixed column, the pressure rod, the push rod, the rubber pad and the tubular hardware workpiece to be sprayed to the middle of the top surface of the base, and then the rotating rod rotates 90 degrees, so that the fixed column, the pressure rod, the push rod, the rubber pad and the tubular hardware workpiece to be sprayed are in a vertical state for spraying by the spray gun. After the workpiece is sprayed, the rotating rod drives the fixed column and the workpiece to rotate 90 degrees again, and then returns the workpiece to between the partitions on the top surface of the support frame, and then the push plate moves the workpiece out of the top surface of the support frame, thereby completing the automatic loading and unloading operation of the workpiece, and further improving the production efficiency.

[0010] Preferably, both sides of the two support plates are fixedly connected with a tooth plate 1; the tooth plate 1 of the support plate on one side is higher than the tooth plate 1 on the surface of the support plate on the other side; both sides of the connecting plate are rotatably connected with a gear 1; the paired tooth plates 1 on the same side are meshingly connected with a gear 1; during operation, when the length of the tubular hardware workpiece to be sprayed is shorter than the spacing between the two support plates, the user can push the support plate on one side to make it approach the support plate on the other side, and since the side surface of the support plate is fixedly connected with a tooth plate 1, the tooth plate 1 will push the gear 1 to rotate, and the gear 1 will drive the tooth plate 1 on the other side to slide, and then drive the support plate on the other side to move together, thereby realizing the relative movement of the two support plates, thereby shortening the spacing between the two support plates, thereby adapting to tubular hardware workpieces with shorter lengths, thereby improving the scope of application of the embodiment of the present invention.

[0011] Preferably, the support frame is fixedly connected to limit plates on both sides of the hydraulic rod; the bottom surface of the hydraulic rod is fixedly connected to a connecting box; both sides of the connecting box are slidably connected to extrusion plates; the extrusion plates are arranged in an L shape; the extrusion plates are located on both sides of the connecting box and are fixedly connected to a spring 1 between the inner wall of the connecting box and the two sides of the connecting box; during operation, when the spacing between the support plates is shortened, the user also needs to pull the extrusion plates apart so that the two extrusion plates move away from each other and compress spring 1 so that the extrusion plates and the connecting box no longer clamp the limit plates, at which time the user can push the connecting box, the hydraulic rod, the connecting plate, the support plate, the partition plate and the push plate toward the base, thereby preventing the tubular hardware workpiece to be sprayed from being too far away from the base, causing the mounting seat to be unable to insert the fixed column into the interior of the tubular hardware workpiece under the drive of the moving seat.

[0012] Preferably, one end of the connecting box away from the base is slidably connected to a top plate; one end of the two extrusion plates close to each other is arranged in an arc shape; the top plate is located between one end of the connecting box and the inner wall of the connecting box and is fixedly connected with a spring 2; during operation, when the user needs to move the connecting box and the connecting plate, the user can push the top plate, and since the connecting box and the extrusion plate clamp the limit plate, the connecting box will not move, and the top plate will be inserted between the two extrusion plates, so that the two extrusion plates move away from each other, and compress the spring 2 and the spring 1, so that the extrusion plate and the connecting box no longer clamp the limit plate, at this time the user can move the connecting plate, and when the connecting plate moves to the desired position, the user no longer squeezes the top plate, the spring 2 recovers, and pushes the top plate out from between the two extrusion plates, and then the two extrusion plates approach each other under the drive of the spring 1, and cooperate with the connecting box to be clamped on the limit plate again, thereby facilitating the user to move the connecting plate, thereby reducing the operating difficulty of the embodiment of the present invention.

[0013] Preferably, the top of the connecting frame is rotatably connected to a connecting rod; the surface of the connecting rod is fixedly connected to a plurality of evenly arranged slides, and the slides and the spray guns are arranged in a one-to-one correspondence; the spray gun is installed on the surface of the slide; one side of the connecting frame is rotatably connected to a vertical rod at the corresponding position of the connecting rod, and the vertical rod and the connecting rod are transmitted by a gear set; the top surface of the base is rotatably connected to a telescopic rod at the corresponding position of the vertical rod, and the telescopic rod and the vertical rod are transmitted by a gear set; the telescopic end of the telescopic rod and the rotating rod are transmitted by a gear set; during operation, when the rotating rod rotates 90 degrees toward the top surface of the base, the rotating rod will drive the telescopic rod to rotate through the gear set, and then the telescopic rod will drive the vertical rod to rotate, and finally the vertical rod will drive the connecting rod to rotate, and then the connecting rod will drive the slide plate and the spray gun to rotate to a horizontal state, thereby avoiding collision between the fixed column and the spray gun when the moving seat drives the fixed column to move.

[0014] Preferably, the surface of the skateboard is rotatably connected to gear 2, and the gear is driven by a servo motor; the surface of the skateboard is slidably connected to a connecting frame, and gear 2 is located on the inner side of the connecting frame; the inner wall of the connecting frame is fixedly connected to tooth plate 2, and tooth plate 2 is meshingly connected to gear 2; the side of the connecting frame away from the skateboard is fixedly connected to the spray gun; during operation, when spraying hardware workpieces with a longer length, in order to ensure that the side surface of the hardware workpiece can be evenly sprayed with paint, the user drives gear 2 to rotate by the servo motor, and then gear 2 drives the tooth plate to move up and down, thereby driving the connecting frame and the spray gun to move up and down, thereby achieving uniform spraying of the hardware workpiece.

[0015] Preferably, a guide bucket is fixedly connected to the side of the base away from the connecting frame; a suction assembly is installed on the side of the guide bucket away from the base; the suction assembly is used to suck the paint mist near the fixed column; during operation, when paint mist is diffused at the fixed column, the suction assembly will suck the paint mist near the fixed column through the guide bucket, thereby preventing the paint mist from diffusing everywhere and being inhaled by the staff, which will have an adverse effect on the health of the staff.

[0016] Preferably, a plurality of evenly arranged fans are fixedly connected to one side of the guide bucket; a duct is fixedly connected to the side of the guide bucket away from the fan; the end of the duct away from the fan is connected to an external paint mist purifier; an angle sensor is installed at the rotating connection between the rotating rod and the base; during operation, when the rotating rod rotates 90 degrees, the angle sensor at the rotating connection between the rotating rod and the base detects the rotation of the rotating rod, and then controls the fan to start, so that the fan blows air toward the duct. At this time, due to the Bernoulli principle, the pressure at the end of the guide bucket away from the base is small, and the paint mist near the fixed column will be sucked into the guide bucket, and then blown into the duct by the fan, and finally introduced into the paint mist purifier by the duct. Since the rotation of the rotating column occurs after the workpiece is sprayed, the suction of the guide bucket will not affect the normal spraying of the workpiece.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The automatic spraying equipment for hardware workpieces described in the present invention fixes the tubular hardware workpiece from the inside through a fixed column and a pressure rod, so that the outside of the tubular hardware workpiece will not be blocked by a clamping component.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 3 As shown, an automatic spraying equipment for hardware workpieces described in an embodiment of the present invention comprises a base 1; a pair of moving seats 2 are slidably connected to the top surface of the base 1, and the moving seats 2 are driven by a servo motor; a rotating rod 3 is rotatably connected between the two moving seats 2; a plurality of evenly arranged mounting seats 4 are fixedly connected to the surface of the rotating rod 3; a fixed column 5 is rotatably connected to the end of the mounting seat 4 away from the rotating rod 3; the fixed column 5 is arranged in a hollow structure, and the fixed column 5 is driven by a servo motor; a plurality of evenly arranged pressing rods 6 are slidably connected to the side surface of the fixed column 5; the fixed column 5 is connected to an external hydraulic control system through a hydraulic rotary joint; a conveying assembly is installed on one side of the base 1; the conveying assembly is used to deliver the tubular hardware workpiece to be sprayed to one side of the moving seat 2; a connecting frame 7 is fixedly connected to the side of the base 1 close to the conveying assembly; a plurality of evenly arranged spray guns 8 are installed on the top of the connecting frame 7; when working, when the tubular hardware workpiece is being sprayed, the spray gun 8 is sprayed on the top of the connecting frame 7. When spraying, the embodiment of the present invention can be used. First, the hardware workpiece to be sprayed will be transported to the base 1 by the conveying component, and then the tubular hardware workpiece will be sleeved on the outside of the fixed column 5. Then, the external hydraulic control system will introduce hydraulic oil into the inside of the fixed column 5, so that the pressure rod 6 will be pressed against the inner surface of the tubular hardware workpiece, thereby fixing the tubular hardware workpiece, and then the spray gun 8 at the connecting frame 7 will spray paint toward the surface of the tubular hardware workpiece at the fixed column 5. During the spraying process, the fixed column 5 at the end face of the mounting seat 4 will also rotate under the drive of the servo motor, thereby driving the tubular hardware workpiece to rotate together, so that the paint is sprayed more evenly. Since the tubular hardware workpiece is fixed from the inside by the fixed column 5 and the pressure rod 6, the outside of the tubular hardware workpiece will not be blocked by the clamping component, and then the fixed column 5 is used to drive the tubular hardware workpiece to rotate, so that the surface of the workpiece can be evenly coated with paint without the need for secondary or multiple spraying, thereby improving work efficiency.

[0032] like Figures 2 to 4As shown, the pressure rod 6 is arranged in a hollow structure; the end of the pressure rod 6 away from the fixed column 5 is slidably connected with a push rod 9; the end of the push rod 9 away from the pressure rod 6 is fixedly connected with a rubber pad 10; the surface of the rubber pad 10 is engraved with anti-skid patterns; during operation, when the hydraulic oil passes into the fixed column 5, the push rod 9 will be pushed to extend out of the pressure rod 6, and the push rod 9 will then push the rubber pad 10 to press the rubber pad 10 against the inner wall of the tubular hardware workpiece, thereby completing the fixation of the tubular hardware workpiece. Through the cooperation of the push rod 9 and the pressure rod 6, the diameter of the tubular hardware workpiece that can be fixed by the push rod 9 and the pressure rod 6 is further expanded. At the same time, the rubber pad 10 and the anti-skid patterns on its surface can also increase the maximum static friction between it and the inner wall of the tubular hardware workpiece, thereby preventing the tubular hardware workpiece from falling off when the fixed column 5 drives the tubular hardware workpiece to rotate.

[0033] like Figure 1 , Figure 6 and Figure 7As shown, the conveying assembly includes a support frame 11; a pair of support plates 12 are installed on the top surface of the support frame 11; a plurality of evenly arranged partitions 13 are fixedly connected to the top surface of the support plate 12, and the top surface of the partition 13 is inclined; the fixed column 5 corresponds to the gap between the pair of partitions 13; a connecting plate 14 is installed between the two support plates 12 on the top surface of the support frame 11, and the support plate 12 and the connecting plate 14 are slidably connected; a hydraulic rod 15 is arranged on the bottom surface of the connecting plate 14; a plurality of evenly arranged push plates 16 are slidably connected to the top surface of the connecting plate 14, and the bottoms of the push plates 16 are fixedly connected together; the hydraulic rod 15 The telescopic end is fixedly connected to the bottom surface of the push plate 16; the top surface of the push plate 16 is inclined, and the push plate 16 is between the paired partitions 13; during operation, when the user needs to transport the tubular hardware workpiece to be sprayed, the conveyor belt can first place the tubular hardware workpiece between the partitions 13 away from one end of the base 1, that is, both ends of the tubular hardware workpiece are between the paired partitions 13, and then the hydraulic rod 15 is started to push the push plate 16 up. Since the top of the push plate 16 is inclined and the top of the partition 13 is also inclined, the push plate 16 will push the tubular hardware workpiece between the paired partitions 13 to the top of the next partition 13, and then the hydraulic rod 15 will push the tubular hardware workpiece between the paired partitions 13 to the top of the next partition 13. The push plate 16 is reset, and the tubular hardware workpiece on the top of the partition 13 will slide to the next pair of partitions 13 along the inclined surface of the top of the partition 13, and then the steps are repeated again, and the tubular hardware workpiece will be moved between the paired partitions 13 near the base 1, and then the rotating rod 3 drives the mounting seat 4 and the fixed column 5 to rotate 90 degrees toward the top surface of the base 1, so that the fixed column 5 is flush with the top surface of the base 1, and then the moving seat 2 drives the rotating rod 3, the mounting seat 4 and the fixed column 5 to move toward the direction of the support frame 11, so that the fixed column 5 is inserted into the tubular hardware workpiece to be sprayed, and then the tubular hardware is fixed by the pressure rod 6, the push rod 9 and the rubber pad 10. The workpiece is then moved to the middle of the top surface of the base 1 by the movable seat 2, and then the fixed column 5, the pressure rod 6, the push rod 9, the rubber pad 10 and the tubular hardware workpiece to be sprayed are moved to the middle of the top surface of the base 1, and then the rotating rod 3 is rotated 90 degrees, so that the fixed column 5, the pressure rod 6, the push rod 9, the rubber pad 10 and the tubular hardware workpiece to be sprayed are in a vertical state for spraying by the spray gun 8. After the workpiece is sprayed, the rotating rod 3 drives the fixed column 5 and the workpiece to rotate 90 degrees again, and then the workpiece is returned to between the partitions 13 on the top surface of the support frame 11, and then the push plate 16 moves the workpiece out of the top surface of the support frame 11, thereby completing the automatic loading and unloading operation of the workpiece, and further improving the production efficiency.

[0034] like Figure 1 and Figure 6As shown, both sides of the two support plates 12 are fixedly connected with tooth plates 17; the tooth plate 17 of one side of the support plate 12 is higher than the tooth plate 17 on the surface of the other side support plate 12; both sides of the connecting plate 14 are rotatably connected with gears 18; the paired tooth plates 17 on the same side are meshed and connected with gears 18; during operation, when the length of the tubular hardware workpiece to be sprayed is shorter than the distance between the two support plates 12, the user can push the support plate 12 on one side to make it approach the support plate 12 on the other side, and since the side surface of the support plate 12 is fixedly connected with the tooth plate 17, the tooth plate 17 will push the gear 18 to rotate, and the gear 18 will drive the tooth plate 17 on the other side to slide, and then drive the support plate 12 on the other side to move together, thereby realizing the relative movement of the two support plates 12, thereby shortening the distance between the two support plates 12, thereby adapting to tubular hardware workpieces with shorter lengths, thereby improving the scope of application of the embodiment of the present invention.

[0035] like Figures 7 and 8 As shown, the support frame 11 is fixedly connected to the limit plates 19 on both sides of the hydraulic rod 15; the bottom surface of the hydraulic rod 15 is fixedly connected to the connection box 20; the two sides of the connection box 20 are slidably connected to the extrusion plates 21; the extrusion plates 21 are arranged in an L shape; the extrusion plates 21 are located on both sides of the connection box 20 and are fixedly connected to the inner wall of the connection box 20 with springs 22; during operation, when the spacing between the support plates 12 is shortened, the user also needs to pull the extrusion plates 21 apart so that the two extrusion plates 21 are away from each other and compress the spring 22 so that the extrusion plates 21 and the connection box 20 no longer clamp the limit plates 19, and at this time the user can push the connection box 20, the hydraulic rod 15, the connection plate 14, the support plate 12, the partition plate 13 and the push plate 16 toward the base 1, thereby preventing the tubular hardware workpiece to be sprayed from being too far away from the base 1, causing the mounting seat 4 to be unable to be driven by the moving seat 2 to insert the fixed column 5 into the interior of the tubular hardware workpiece.

[0036] like Figure 8As shown, the end of the connection box 20 away from the base 1 is slidably connected with a top plate 23; the ends of the two extrusion plates 21 close to each other are arranged in an arc shape; the top plate 23 is located between one end of the connection box 20 and the inner wall of the connection box 20 and is fixedly connected with a spring 24; during operation, when the user needs to move the connection box 20 and the connection plate 14, the user can push the top plate 23, and since the connection box 20 and the extrusion plate 21 clamp the limit plate 19, the connection box 20 will not move, and the top plate 23 will be inserted between the two extrusion plates 21, so that the two extrusion plates 21 are far away from each other. The spring 24 and the spring 1 22 are separated and compressed, so that the extrusion plate 21 and the connection box 20 no longer clamp the limit plate 19. At this time, the user can move the connection plate 14. When the connection plate 14 moves to the desired position, the user no longer squeezes the top plate 23, the spring 24 recovers and pushes the top plate 23 out from between the two extrusion plates 21. Subsequently, the two extrusion plates 21 approach each other under the drive of the spring 1 22 and are clamped on the limit plate 19 again with the connection box 20, so as to facilitate the user to move the connection plate 14, thereby reducing the difficulty of operation of the embodiment of the present invention.

The gear group is used for transmission; the telescopic end of the telescopic rod 28 and the rotating rod 3 are driven by the gear group; when working, when the rotating rod 3 rotates 90 degrees toward the top surface of the base 1, the rotating rod 3 will drive the telescopic rod 28 to rotate through the gear group, and then the telescopic rod 28 drives the vertical rod 27 to rotate, and finally the vertical rod 27 drives the connecting rod 25 to rotate, and then the connecting rod 25 drives the slide plate 26 and the spray gun 8 to rotate to a horizontal state, thereby avoiding the collision between the fixed column 5 and the spray gun 8 when the movable seat 2 drives the fixed column 5 to move.

[0038] like Figure 3 and Figure 5As shown, the surface of the slide plate 26 is rotatably connected to a gear 29, and the gear is driven by a servo motor; the surface of the slide plate 26 is slidably connected to a connecting frame 30, and the gear 29 is located on the inner side of the connecting frame 30; the inner wall of the connecting frame 30 is fixedly connected to a tooth plate 21, and the tooth plate 21 is meshingly connected to the gear 29; the side of the connecting frame 30 away from the slide plate 26 is fixedly connected to the spray gun 8; during operation, when spraying a hardware workpiece with a longer length, in order to ensure that the side surface of the hardware workpiece can be evenly sprayed with paint, the user drives the gear 29 to rotate through the servo motor, and then the gear 29 drives the tooth plate to move up and down, thereby driving the connecting frame 30 and the spray gun 8 to move up and down, thereby achieving uniform spraying of the hardware workpiece.

[0039] like Figure 1 to Figure 2 As shown, a guide bucket 32 ​​is fixedly connected to the side of the base 1 away from the connecting frame 7; a suction assembly is installed on the side of the guide bucket 32 ​​away from the base 1; the suction assembly is used to suck the paint mist near the fixed column 5; during operation, when paint mist is diffused at the fixed column 5, the suction assembly will suck the paint mist near the fixed column 5 through the guide bucket 32, thereby preventing the paint mist from diffusing everywhere and being inhaled by the staff, which will have an adverse effect on the health of the staff.

[0040] like Figure 1 to Figure 2 As shown, a plurality of evenly arranged fans 33 are fixedly connected to one side of the guide bucket 32; a duct 34 is fixedly connected to the side of the guide bucket 32 ​​away from the fan 33; the end of the duct 34 away from the fan 33 is connected to an external paint mist purifier; an angle sensor is installed at the rotation connection between the rotating rod 3 and the base 1; during operation, when the rotating rod 3 rotates 90 degrees, the angle sensor at the rotation connection between the rotating rod 3 and the base 1 detects the rotation of the rotating rod 3, and then controls the fan 33 to start, so that the fan 33 blows air toward the duct 34. At this time, due to the Bernoulli principle, the pressure at the end of the guide bucket 32 ​​away from the base 1 is small, and the paint mist near the fixed column 5 will be sucked into the guide bucket 32, and then blown into the duct 34 by the fan 33, and finally introduced into the paint mist purifier by the duct 34. Since the rotation of the rotating column occurs after the workpiece is sprayed, the suction of the guide bucket 32 ​​will not affect the normal spraying of the workpiece.

[0041] During operation, when spraying a tubular hardware workpiece, the embodiment of the present invention can be used. First, the hardware workpiece to be sprayed will be transported to the base 1 by the conveying component, and then the tubular hardware workpiece will be sleeved on the outside of the fixed column 5. Then, the external hydraulic control system will introduce hydraulic oil into the inside of the fixed column 5, so that the pressure rod 6 will be pressed against the inner surface of the tubular hardware workpiece, thereby fixing the tubular hardware workpiece. Then, the spray gun 8 at the connecting frame 7 will spray paint toward the surface of the tubular hardware workpiece at the fixed column 5. During the spraying process, the fixed column 5 at the end face of the mounting seat 4 will also rotate under the drive of the servo motor, thereby driving the tubular hardware workpiece to rotate together, so that the paint is sprayed more evenly. Since the tubular hardware workpiece is fixed from the inside by the fixed column 5 and the pressure rod 6, the outside of the tubular hardware workpiece will not be blocked by the clamping component. Then, the fixed column 5 is used to drive the tubular hardware workpiece to rotate, so that the surface of the workpiece can be evenly coated with paint without the need for secondary or multiple spraying, thereby improving work efficiency.

[0042] When the hydraulic oil flows into the fixing column 5, it will push the push rod 9 to extend out of the pressure rod 6, and then the push rod 9 will push the rubber pad 10, so that the rubber pad 10 will be pressed against the inner wall of the tubular hardware workpiece, thereby completing the fixation of the tubular hardware workpiece. Through the cooperation of the push rod 9 and the pressure rod 6, the diameter of the tubular hardware workpiece that can be fixed by the push rod 9 and the pressure rod 6 is further expanded. At the same time, the rubber pad 10 and the anti-slip grooves on its surface can also increase the maximum static friction between it and the inner wall of the tubular hardware workpiece, thereby preventing the tubular hardware workpiece from falling off when the fixing column 5 drives the tubular hardware workpiece to rotate.

[0043] When the user needs to transport the tubular hardware workpiece to be sprayed, the conveyor belt can first place the tubular hardware workpiece between the partitions 13 away from one end of the base 1, that is, both ends of the tubular hardware workpiece are between the paired partitions 13, and then the hydraulic rod 15 starts to push the push plate 16 to rise. Since the top of the push plate 16 is inclined and the top of the partition 13 is also inclined, the push plate 16 will push the tubular hardware workpiece between the paired partitions 13 to the top of the next partition 13, and then the hydraulic rod 15 drives the push plate 16 to reset, and the tubular hardware workpiece on the top of the partition 13 will slide along the inclined surface of the top of the partition 13 to between the next pair of partitions 13, and then repeat the steps again, and the tubular hardware workpiece will be moved between the paired partitions 13 near the base 1, and then the rotating rod 3 drives the mounting seat 4 and the fixing column 5 to rotate 90 degrees toward the top surface of the base 1, so that the fixing column 5 is flush with the top surface of the base 1 After the spray gun 8 is sprayed, the rotating rod 3 drives the fixed column 5 and the workpiece to be sprayed to a vertical position, and then the workpiece is returned to between the partitions 13 on the top surface of the support frame 11, and the workpiece is moved out of the top surface of the support frame 11 by the push plate 16, thereby completing the operation of automatic loading and unloading of the workpiece, and improving the production efficiency.

[0044] When the length of the tubular hardware workpiece to be sprayed is shorter than the distance between the two support plates 12, the user can push the support plate 12 on one side to make it approach the support plate 12 on the other side. Since the side surface of the support plate 12 is fixedly connected with a tooth plate 17, the tooth plate 17 will push the gear 18 to rotate, and the gear 18 will drive the tooth plate 17 on the other side to slide, thereby driving the support plate 12 on the other side to move together, thereby realizing the opposite movement of the two support plates 12, thereby shortening the distance between the two support plates 12, so as to adapt to the tubular hardware workpiece with shorter length, thereby improving the scope of application of the embodiment of the present invention.

[0045] When the distance between the support plates 12 is shortened, the user also needs to pull the extrusion plates 21 apart so that the two extrusion plates 21 move away from each other and compress the spring 1 22 so that the extrusion plates 21 and the connection box 20 no longer clamp the limit plate 19. At this time, the user can push the connection box 20, the hydraulic rod 15, the connection plate 14, the support plate 12, the partition plate 13 and the push plate 16 toward the base 1, thereby preventing the tubular hardware workpiece to be sprayed from being too far away from the base 1, which causes the mounting seat 4 to be unable to be driven by the moving seat 2 to insert the fixing column 5 into the interior of the tubular hardware workpiece.

[0046] When the user needs to move the connecting box 20 and the connecting plate 14, the user can push the top plate 23. Since the connecting box 20 and the extrusion plate 21 clamp the limit plate 19, the connecting box 20 will not move, and the top plate 23 will be inserted between the two extrusion plates 21, so that the two extrusion plates 21 move away from each other and compress the spring 24 and the spring 1 22, so that the extrusion plate 21 and the connecting box 20 no longer clamp the limit plate 19. At this time, the user can move the connecting plate 14. When the connecting plate 14 moves to the desired position, the user no longer squeezes the top plate 23, the spring 24 recovers, and pushes the top plate 23 out from between the two extrusion plates 21. Subsequently, the two extrusion plates 21 approach each other under the drive of the spring 1 22, and re-cooperate with the connecting box 20 to be clamped on the limit plate 19, thereby facilitating the user to move the connecting plate 14, thereby reducing the operating difficulty of the embodiment of the present invention.

[0047] When the rotating rod 3 rotates 90 degrees toward the top surface of the base 1, the rotating rod 3 will drive the telescopic rod 28 to rotate through the gear set, and then the telescopic rod 28 will drive the vertical rod 27 to rotate, and finally the vertical rod 27 will drive the connecting rod 25 to rotate, and then the connecting rod 25 will drive the slide plate 26 and the spray gun 8 to rotate to a horizontal state, thereby preventing the fixed column 5 from colliding with the spray gun 8 when the movable seat 2 drives the fixed column 5 to move.

[0048] When spraying a hardware workpiece with a longer length, in order to ensure that the side surface of the hardware workpiece can be evenly sprayed with paint, the user drives the gear 29 to rotate through the servo motor, and then the gear 29 drives the tooth plate to move up and down, thereby driving the connecting frame 30 and the spray gun 8 to move up and down, thereby achieving uniform spraying of the hardware workpiece.

[0049] When paint mist is diffused at the fixed column 5, the suction assembly will suck the paint mist near the fixed column 5 through the guide bucket 32, thereby preventing the paint mist from diffusing everywhere and being inhaled by the staff, which will have an adverse effect on the health of the staff.

[0050] When the rotating rod 3 rotates 90 degrees, the angle sensor at the rotating connection between the rotating rod 3 and the base 1 detects the rotation of the rotating rod 3 and controls the fan 33 to start, so that the fan 33 blows air toward the duct 34. At this time, due to the Bernoulli principle, the pressure at the end of the guide bucket 32 ​​away from the base 1 is small, and the paint mist near the fixed column 5 will be sucked into the guide bucket 32, and then blown into the duct 34 by the fan 33, and finally introduced into the paint mist purifier by the duct 34. Since the rotation of the rotating column occurs after the workpiece is sprayed, the suction of the guide bucket 32 ​​will not affect the normal spraying of the workpiece.
