Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bar conveying equipment, specifically a bar spraying and conveying equipment. Background Technology
[0002] The bar coating conveying equipment is a specialized device used in automated coating production lines. It is primarily used to stably transport metal or non-metal bars (such as steel pipes, aluminum, and plastic bars) to the coating station and, in conjunction with spray guns, complete the surface coating treatment. This equipment typically consists of a conveyor track, clamping mechanism, rotary drive device, and synchronous control system. It enables continuous feeding, uniform rotation, and precise positioning of the bars, ensuring even coating coverage without any blind spots.
[0003] Existing rod coating and conveying equipment has certain shortcomings in its linkage structure. The support structure of its linkage components often lacks symmetry, which may lead to uneven force distribution during movement. This results in poor synchronization of the opening and closing of the positioning clamps, sometimes causing misalignment of the clamping positions on both sides. Consequently, the center of the rod may be misaligned with the coating center, affecting the coating accuracy. To address this, we propose a rod coating and conveying equipment. Utility Model Content
[0004] The purpose of this utility model is to provide a rod spraying and conveying equipment to solve the problem that the linkage structure of the existing rod spraying and conveying equipment mentioned in the background art has certain shortcomings. The support structure of its linkage components often lacks symmetry, which may lead to uneven force during movement, resulting in poor synchronization of the opening and closing action of the positioning clamp. Sometimes, the clamping positions on both sides may shift, which may cause the center of the rod and the spraying center to be misaligned, affecting the spraying accuracy.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a bar spraying and conveying equipment, comprising: a conveyor frame, a spraying machine fixedly connected to the outer surface of the conveyor frame, and a positioning component provided on the side surface of the conveyor frame, the positioning component stabilizing and positioning the bar.
[0006] The positioning assembly includes a fixed plate and a fixed base. A third connecting post is fixedly connected through the side surface of the fixed base. A first linkage plate is fixedly connected to the output end of the third connecting post. A first connecting post is fixedly connected to the upper surface of the first linkage plate. A first linkage rod is sleeved on the top of the first connecting post. A second connecting post is sleeved on the end of the first linkage rod away from the first connecting post. An adjusting rotating rod is fixedly connected to the bottom of the second connecting post. A positioning shaft is movably connected to the center of the adjusting rotating rod. The bottom of the positioning shaft is fixedly connected to the upper surface of the center of the fixed base.
[0007] The fixed plate is movably connected to the side surface of the conveyor frame. The outer surface of the fixed plate is movably connected to a fixing bolt. The upper surface of the fixed plate is fixedly connected to a support frame. The top two sides of the support frame are fixedly connected to fixing rings. The inside of the fixing rings is fixedly connected to a sliding rod. The two ends of the sliding rod are fixedly connected to anti-rotation sleeves.
[0008] The first linkage plate is movably connected to the outer surface of the sliding rod, and guide rings are fixedly connected to both sides of the first linkage plate. The sliding rod is movably connected inside the guide rings.
[0009] The positioning shaft is fixedly connected to a third connecting column at the end away from the adjusting rod. A second linkage rod is sleeved on the top of the third connecting column. A fourth connecting column is movably connected to the end of the second linkage rod away from the third connecting column.

[0012] This utility model has at least the following beneficial effects:
[0013] 1. In use, this utility model provides balanced support for the linkage components through the fixed seat and telescopic cylinder, and the connection structure between the fixed seat and two sets of symmetrical sliding rods. Combined with the drive connection between the telescopic cylinder and the first linkage plate, it achieves automated control of positioning adjustment, reducing the intensity of manual operation. The first and second linkage plates slide along the sliding rods via guide rings. The linkage structure of the first and second linkage rods and the adjusting rotating rod enables the two sets of positioning clamps to move synchronously in opposite directions, ensuring the consistency of the clamping center. This allows for stable clamping of rods of different diameters, preventing loosening or displacement of the rods during transport, and improving the stability and pass rate of the spray coating process.
[0014] 2. In use, this utility model achieves a movable connection between the positioning component and the conveying frame through the cooperation of the fixing plate and the fixing bolt. This ensures the stability of the overall structure and allows for flexible adjustment of the installation position of the positioning component according to the specifications of the bar, improving the adaptability of the equipment to different processing scenarios. At the same time, the support frame fixes the sliding rod with a fixing ring, and the anti-rotation sleeves at both ends of the sliding rod effectively limit its rotation and displacement, providing stable guidance for the linkage components, avoiding positioning deviations caused by the swaying of the sliding rod, ensuring the positional accuracy of the bar during the conveying process, and reducing the problem of spraying deviation.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a bar spraying and conveying equipment, including: a conveyor frame 1, a spraying machine 2 fixedly connected to the outer surface of the conveyor frame 1, and a positioning component 3 provided on the side surface of the conveyor frame 1, the positioning component 3 stabilizing and positioning the bar.
[0022] In use, the fixed base 314 and telescopic cylinder 319, and the connection structure between the fixed base 314 and the two sets of symmetrical sliding rods 35, provide balanced support for the linkage components. With the drive connection between the telescopic cylinder 319 and the first linkage plate 38, the positioning adjustment is automatically controlled, reducing the intensity of manual operation. The first linkage plate 38 and the second linkage plate 318 slide along the sliding rod 35 through the guide ring 37. Combined with the linkage structure of the first linkage rod 310, the second linkage rod 316 and the adjusting rotating rod 312, the two sets of positioning clamping plates 321 move synchronously in opposite directions, ensuring the consistency of the clamping center, adapting to the stable clamping of rods of different diameters, avoiding the loosening or displacement of the rods during the conveying process, and improving the stability and pass rate of the spraying process.
[0023] The positioning component 3 includes a fixing plate 31 and a fixing seat 314. A third connecting post 315 is fixedly connected through the side surface of the fixing seat 314. A first linkage plate 38 is fixedly connected to the output end of the third connecting post 315. A first connecting post 39 is fixedly connected to the upper surface of the first linkage plate 38. A first linkage rod 310 is sleeved on the top of the first connecting post 39. A second connecting post 311 is sleeved on the end of the first linkage rod 310 away from the first connecting post 39. An adjusting rotating rod 312 is fixedly connected to the bottom of the second connecting post 311. A positioning shaft 313 is movably connected to the center of the adjusting rotating rod 312. The bottom of the positioning shaft 313 is fixedly connected to the upper surface of the center of the fixing seat 314.
[0024] The fixed plate 31 is movably connected to the side surface of the conveyor frame 1. The outer surface of the fixed plate 31 is movably connected to the fixing bolt 32. The upper surface of the fixed plate 31 is fixedly connected to the support frame 33. The top two sides of the support frame 33 are fixedly connected to the fixing ring 34. The inside of the fixing ring 34 is fixedly connected to the sliding rod 35. The two ends of the sliding rod 35 are fixedly connected to the anti-rotation sleeve 36.
[0025] The first linkage plate 38 is movably connected to the outer surface of the sliding rod 35. Guide rings 37 are fixedly connected to both sides of the first linkage plate 38, and the sliding rod 35 passes through and is movably connected inside the guide rings 37. The end of the positioning shaft 313 away from the adjusting rod 312 is fixedly connected to the third connecting post 315. The top of the third connecting post 315 is sleeved with the second linkage rod 316. The end of the second linkage rod 316 away from the third connecting post 315 is movably connected to the fourth connecting post 317. The bottom end of the fourth connecting post 317 is fixedly connected to the second linkage plate 318. Guide rings 37 are fixedly connected to both sides of the second linkage plate 318. The bottom of the first linkage plate 38 is fixedly connected to the connecting block 320. The bottom of the connecting block 320 is fixedly connected to the second connecting post 311. The connecting block 320 and the positioning clamp 321 form two sets, and the other set is fixedly connected to the bottom of the second linkage plate 318. The fixed base 314 is fixedly connected to the outer surface of the center of the sliding rod 35, and the sliding rod 35 is symmetrically connected to the left and right ends of the fixed base 314 in two sets.
[0026] During use, the installation and fixation of the positioning component 3 provides a foundation for the stable operation of the equipment: the fixing plate 31 is movably connected to the side surface of the conveyor frame 1 through the fixing bolt 32. This connection method not only ensures the stable connection between the positioning component 3 and the conveyor frame 1, but also facilitates the adjustment of the installation position of the positioning component 3 according to construction needs, improving the adaptability and flexibility of the equipment; the support frame 33 on the upper surface of the fixing plate 31 fixes the sliding rod 35 through the fixing rings 34 on both sides of the top end. The anti-rotation sleeves 36 at both ends of the sliding rod 35 effectively restrict the rotation and axial displacement of the sliding rod 35, ensuring that the sliding rod 35 always maintains a horizontal and stable state, providing precise guidance for the movement of subsequent linkage components, avoiding positioning deviation caused by the shaking of the sliding rod 35, and ensuring positioning accuracy.
[0027] The fixed base 314, as the core support of the linkage structure, is fixedly connected to the outer surface of the center of the sliding rod 35. The two sets of sliding rods 35 symmetrically pass through the left and right ends of the fixed base 314. This symmetrical structural design makes the fixed base 314 evenly stressed, which greatly reduces the risk of deformation after long-term use and extends the service life of the equipment. The output end of the telescopic cylinder 319 on the side surface of the fixed base 314 is connected to the first linkage plate 38, providing a power source for positioning adjustment. Compared with the traditional manual adjustment method, automatic control can be achieved by driving the telescopic cylinder 319, which significantly improves the adjustment efficiency and reduces the intensity of manual operation.
[0028] When the bar needs to be positioned, the telescopic cylinder 319 extends and retracts, causing the first linkage plate 38 to move. The first linkage plate 38 slides smoothly along the sliding rod 35 through the guide rings 37 on both sides. The cooperation between the guide rings 37 and the sliding rod 35 reduces the frictional resistance during the movement, making the sliding smoother, avoiding jamming, and ensuring the continuity of the adjustment process. At the same time, the first connecting post 39 on the first linkage plate 38 drives the first linkage rod 310 to swing. The first linkage rod 310 drives the adjusting rod 312 to rotate around the positioning shaft 313 through the second connecting post 311. The positioning shaft 313 is fixed to the center of the fixed seat 314, ensuring that the adjusting rod 312 achieves lever movement with a stable fulcrum, so that the linkage structure at both ends is balanced by force.
[0029] While the adjusting rod 312 rotates, its other end drives the second linkage rod 316 to swing via the third connecting column 315. The second linkage rod 316 pulls the second linkage plate 318 via the fourth connecting column 317, causing the second linkage plate 318 to move synchronously with the first linkage plate 38 along the sliding rod 35 via the guide ring 37. This linkage structure design ensures that the movement accuracy of the two sets of linkage plates is consistent, ensuring that the clamping center of the subsequent positioning clamping plate 321 is always aligned with the spraying center of the spraying machine 2, effectively avoiding spraying eccentricity caused by clamping offset and improving the consistency of spraying quality.
[0030] The first linkage plate 38 and the second linkage plate 318 are connected at the bottom by a connecting block 320 to two sets of positioning clamping plates 321. As the linkage plates move relative to each other or towards each other, they move closer or further apart. When the bar enters the positioning area, the positioning clamping plates 321 move closer and clamp the bar synchronously. The clamping force can be precisely controlled by the output force of the telescopic cylinder 319, which can ensure that the bar is stable and does not loosen, and avoid damage to the surface of the bar caused by over-clamping. At the same time, since the two sets of positioning clamping plates 321 have high synchronization of movement, they can be adapted to bars of different diameters. They can meet the positioning needs of bars of various specifications without changing parts, which significantly improves the versatility of the equipment.
