Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and more specifically, to a spraying auxiliary balancing hoist. Background Technology

[0002] In the production and processing of steel structure workpieces, there is a considerable amount of painting processing. Each workpiece needs to be painted during the processing, and this processing step plays an important role in the quality and assembly of the product.

[0003] Existing spraying equipment often relies on the fixed angle and position of the nozzle for spraying. The workpiece itself is difficult to rotate in all directions, resulting in a large number of spraying blind spots on the workpiece surface. The paint cannot be evenly covered, and there will be local overspray or missed spraying. This not only affects the appearance of the product, but also reduces the protective performance of the product.

[0004] Therefore, we have made improvements to this and proposed a spraying auxiliary balancing hoist. Utility Model Content

[0005] The purpose of this invention is to address the fact that existing spraying equipment often relies on the fixed angle and position of the nozzle for spraying, making it difficult for the workpiece to rotate in all directions. This results in a large number of blind spots on the workpiece surface, making it impossible for the paint to cover the surface evenly, leading to local overspraying or underspraying, which not only affects the appearance of the product but also reduces its protective performance.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A spraying auxiliary balancing hanger includes a base, a vertical block mounted on top of the base, a spraying assembly mounted on top of the base, a top plate mounted on the side of the vertical block above the base, a geared motor fixedly mounted on the top of the top plate, a fixing ring mounted on the bottom of the top plate, a rotating rod mounted on the output shaft of the geared motor between the top plate and the base, a rotating assembly between the fixing ring and the rotating rod, a fixing assembly mounted on the periphery below the rotating rod, and a drip tray placed on top of the base.

[0008] Furthermore, the spraying assembly includes a material hopper fixedly installed above the base, a pump body fixedly installed above the material hopper, and the feed pipe of the pump body extending into the interior of the material hopper.

[0009] Furthermore, a spraying plate with multiple nozzles on one side is fixedly installed on the top of the base, and a conveying pipe is installed between the inlet of the spraying plate and the outlet of the pump body.

[0011] Furthermore, each of the four corners of the fixing frame is rotatably fitted with a rotating rod, and the rotating rod is equipped with a gear that meshes with the sector-shaped toothed block on its circumferential side below the fixing frame, and a pressure block is installed at the bottom end of the rotating rod.

[0012] Furthermore, the fixing assembly includes an adjusting frame that slides around the lower periphery of the rotating rod. The adjusting frame is cross-shaped. A limiting groove penetrating both sides is provided on the lower periphery of the rotating rod. A limiting block that slides around the limiting groove is installed in the middle of the adjusting frame. A screw that passes through the limiting groove and is threadedly engaged with the limiting block is rotatably fitted at the bottom of the rotating rod.

[0013] Furthermore, each of the four sides of the adjustment frame is slidably fitted with a moving strip, and a fixed block is installed on the outer side of the moving strip.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please refer to Figure 1-5 A spraying auxiliary balancing hanger includes: a base 1, a vertical block 2 mounted on the top of the base 1, a spraying assembly 3 mounted on the top of the base 1, a top plate 4 mounted on the side of the vertical block 2 above the base 1, a reduction motor 5 fixedly mounted on the top of the top plate 4, a fixing ring 6 mounted on the bottom of the top plate 4, a rotating rod 7 mounted on the output shaft of the reduction motor 5 between the top plate 4 and the base 1, a rotating assembly 8 between the fixing ring 6 and the rotating rod 7, a fixing assembly 9 mounted on the periphery below the rotating rod 7, and a drip tray 10 placed on the top of the base 1.

[0028] Specifically, during the entire spraying process, due to the splashing and dripping of paint during spraying, the drip tray 10 located above the base 1 plays an important role. The drip tray 10 adopts a shallow tray design, and its opening area is larger than the projected area of ​​the spray plate 33 and the workpiece, which can completely cover the area where paint may drip. When paint drips from the surface of the workpiece or the nozzle, it falls directly into the drip tray 10 under the action of gravity. The paint collected by the drip tray 10 can be cleaned and recycled regularly.

[0029] Please refer to Figure 1 The spraying assembly 3 includes a material box 31 fixedly installed above the base 1, a pump body 32 fixedly installed above the material box 31, the feed pipe of the pump body 32 extending into the interior of the material box 31, a spraying plate 33 with multiple nozzles on one side fixedly installed above the base 1, and a conveying pipe 34 installed between the feed inlet of the spraying plate 33 and the discharge outlet of the pump body 32.

[0030] Specifically, when the spraying operation starts, the pump body 32 is powered on and begins to operate. The impeller inside the pump body 32 rotates at high speed, creating a negative pressure environment under the action of centrifugal force. The paint in the material box 31 is pushed into the pump body 32 through the feed pipe under atmospheric pressure. After the pump body 32 pressurizes the paint, it is transported to the spraying plate 33 through the conveying pipe 34. Multiple nozzles evenly distributed on one side of the spraying plate 33 atomize the paint into fine particles under the action of high pressure and spray them onto the surface of the workpiece.

[0031] Please refer to Figure 2 The rotating assembly 8 includes a fixing frame 81 mounted on the periphery above the rotating rod 7 and located inside the fixing ring 6. The fixing frame 81 is cross-shaped. The inner wall of the fixing ring 6 is equipped with a sector-shaped toothed block 82 corresponding to the spray plate 33. The four corners of the fixing frame 81 are rotatably fitted with rotating rods 83. The periphery of the rotating rod 83 located below the fixing frame 81 is equipped with a gear 84 that meshes with the sector-shaped toothed block 82. The bottom end of the rotating rod 83 is equipped with a pressure block 85. The arc length of the sector-shaped toothed block 82 is equal to the periphery of the gear 84, so that the pressure block 85 rotates once during the time period when the gear 84 meshes with the sector-shaped toothed block 82.

[0032] Specifically, the output shaft of the geared motor 5 drives the rotating rod 7 to rotate in a circular motion. The fixed frame 81 above the rotating rod 7 rotates synchronously with the rotating rod 7. Since the fixed frame 81 is cross-shaped and the rotating rods 83 at its four corners are rotatably engaged with the fixed frame 81, when the fixed frame 81 rotates, the gear 84 on the rotating rod 83 begins to mesh with the sector-shaped tooth block 82 on the inner wall of the fixed ring 6. Because the arc length of the sector-shaped tooth block 82 is equal to the circumference of the gear 84, during the period when the gear 84 and the sector-shaped tooth block 82 are engaged, the gear 84 will rotate one revolution under the drive of the sector-shaped tooth block 82, thereby driving the pressure block 85 at the bottom of the rotating rod 83 to rotate one revolution. The pressure block 85, through contact with the workpiece, drives the workpiece to rotate, so that all parts of the workpiece surface can be evenly sprayed by the nozzle, effectively reducing the occurrence of blind spots in the spraying and improving the uniformity of the spraying.

[0033] Please refer to Figure 3-5 The fixing component 9 includes an adjusting frame 91 that is slidably fitted on the lower periphery of the rotating rod 7. The adjusting frame 91 is cross-shaped. A limiting groove 92 penetrating both sides is provided on the lower periphery of the rotating rod 7. A limiting block 93 that slidably fits the limiting groove 92 is installed in the middle of the adjusting frame 91. A screw 94 that penetrates into the limiting groove 92 and is threadedly fitted to the limiting block 93 is rotatably fitted on the bottom of the rotating rod 7. Moving strips 95 are slidably fitted on all four sides of the adjusting frame 91. A fixing block 96 is installed on the outer side of the moving strip 95. The bottom of the fixed block 96 is slidably fitted with a pre-clamping rod 97 that extends to the top. The top of the pre-clamping rod 97 is provided with a base 98. The bottom of the base 98 is rotatably fitted with a rotating block 99 that is fixedly installed at the top of the pre-clamping rod 97. A pre-clamping spring 910 is installed between the bottom of the rotating block 99 and the upper side of the fixed block 96. The bottom of the adjusting frame 91 is threaded with a positioning bolt 911. The bottom of the moving bar 95 is provided with multiple positioning grooves 912, and the positioning bolts 911 cooperate with the positioning grooves 912.

[0034] Specifically, during the workpiece fixing operation, the workpiece to be sprayed is carefully placed on the chassis 98. Then, the screw 94 is rotated. Due to the threaded engagement between the screw 94 and the limiting block 93, the screw 94 rotates, causing the adjusting bracket 91 to slide up and down along the circumference below the rotating rod 7. During this process, the operator can precisely adjust the height of the adjusting bracket 91 according to the actual size of the workpiece to ensure that the fixing components and the workpiece are in the correct vertical position. After the height adjustment is complete, the moving strip 95 is slid down. By changing the position of the moving strip 95, the position of the fixing block 96 is adjusted. When the fixing block 96 moves to the appropriate position, the pre-clamping rod 97 will fit tightly against the workpiece surface. At this time, the pre-clamping spring 910 plays its role, generating pre-tightening force through its elastic deformation to initially fix the workpiece and prevent significant displacement during subsequent operations. Finally, by screwing the positioning bolt 911 into the positioning groove 912 corresponding to the bottom of the moving strip 95, the moving strip 95 is fixed in place using the cooperation between the two. This secures the workpiece firmly, ensuring a stable and reliable fixation and guaranteeing its stability during subsequent coating processes.
