Description

Technical Field

[0001] This utility model relates to the field of coating production equipment technology, and in particular to a suspended conveyor device for coating workshops. Background Technology

[0002] In modern industrial production, coating processes are widely used in many fields such as automobile manufacturing, machining, and furniture production, with the aim of giving workpieces an aesthetically pleasing appearance and good corrosion resistance. With the rapid development of the industry, the requirements for production efficiency, product quality, and the degree of automation in coating workshops are becoming increasingly stringent. Among these requirements, overhead conveyor systems, as key equipment for achieving continuous and automated production in coating workshops, play a crucial role.

[0003] When existing technical solutions are used,

[0004] (1) The workpiece suspension method is simple and difficult to adapt to workpieces of different shapes. During the transportation process, the workpiece is prone to shaking, shifting or even falling due to factors such as transmission vibration. This not only affects the uniformity of coating quality, but may also cause damage to the workpiece surface and increase the defect rate.

[0005] (2) The drying efficiency is low. The drying mechanism of the conveying device is simple in function. The air drying and baking processes are separated, resulting in a long drying time for the workpiece. Moreover, the height of the drying device is fixed, making it difficult to adapt to the drying needs of workpieces of different sizes, and the energy utilization efficiency is low.

[0006] To address the above problems, this utility model provides a suspended conveyor device for painting workshops. Utility Model Content

[0007] The purpose of this invention is to solve the problems of unstable workpiece suspension and low drying efficiency in the existing technology, and to propose a suspended conveying device for painting workshops.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a suspended conveying device for a painting workshop, comprising a support frame, a transmission conveying mechanism, an air drying mechanism, and a drying mechanism, wherein the transmission conveying mechanism is fixedly connected to the inner top wall of the support frame, and the transmission conveying mechanism includes a connecting frame fixedly connected to the outer surface of the support frame, wherein a transmission component is fixedly connected inside the connecting frame;

[0009] The transmission and conveying mechanism includes a rotating hook and a safety positioning column. The rotating hook is threadedly connected to the transmission component, and the safety positioning column is threadedly connected to the inside of the support frame. Bolts are threadedly connected to both ends of the safety positioning column.

[0010] A connecting plate is fixedly connected to the top of the rotating hook, and a limiting ring is fixedly connected to the top of the connecting plate. The limiting ring is slidably connected to the outer surface of the safety positioning column, and a sliding block is fixedly connected to the top of the limiting ring. The sliding block and the limiting ring are symmetrically arranged inside the support frame.

[0011] Furthermore, a positioning plate is fixedly connected to the bottom of the symmetrically arranged connecting plate, and an adjuster is threadedly connected to both sides of the positioning plate. A clamping plate is rotatably connected to the far end of the adjuster, and the adjuster and the clamping plate are symmetrically arranged on both sides of the positioning plate.

[0012] Furthermore, the transmission assembly includes a first motor fixedly connected inside the connecting frame, the output end of the first motor being fixedly connected to a main rotating shaft, a rotating belt being rotatably connected to the outer surface of the main rotating shaft, and a driven rotating shaft being rotatably connected inside the rotating belt, the driven rotating shaft rotating synchronously with the main rotating shaft under the drive of the rotating belt.

[0013] Furthermore, a rotating threaded rod is fixedly connected to the outer surface of the main rotating shaft and the driven rotating shaft, and a bearing is rotatably connected to the distal end of the rotating threaded rod. The outer surface of the bearing is fitted into the interior of the support frame, and the sliding block is threadedly connected to the outer surface of the rotating threaded rod.

[0014] Furthermore, the drying mechanism includes a fixed plate fixedly connected to the top of the support frame, a second motor fixedly connected to the top of the fixed plate, and a double-layer drying fan fixedly connected to the output end of the second motor. The double-layer drying fan and the second motor are symmetrically arranged on both sides of the support frame.

[0015] Furthermore, the drying mechanism includes support columns fixedly connected to the four corners of the bottom of the support frame. The outer surface of the support column is provided with threaded holes at equal intervals. A fixing frame is threadedly connected to the outer surface of the support column, and limiters are threadedly connected to both sides of the fixing frame.

[0016] Furthermore, a heating tube is fixedly connected inside the fixed frame, an isolation plate is snapped onto the top of the fixed frame, and the fixed frame and the heating tube are threadedly connected to the outer surface of the support column through a limiting member.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, the rotating hook, safety positioning column, and clamping plate provide a flexible suspension angle. The safety positioning column, together with the limiting ring and sliding block, restricts the displacement of the rotating hook from both sides to prevent it from shaking. The clamping plate provides a stable clamping for workpieces of different sizes. The spacing between the clamping plates can be flexibly adjusted by the rotary adjuster to adapt to workpieces of different sizes, achieving stable clamping of the workpiece and further enhancing the stability of the workpiece suspension. The multi-dimensional fixing method effectively controls the shaking amplitude of the workpiece during the conveying process to a very small range, greatly improving the stability of the workpiece suspension, thereby ensuring the uniformity of the coating quality and effectively reducing the defect rate.

[0019] 2. In this utility model, the symmetrical layout of the double-layer drying fan, heating tube, and isolation plate ensures that the workpiece is uniformly blown by air from both sides during the conveying process, achieving an all-round and efficient drying effect, effectively shortening the drying time of the workpiece. In the drying mechanism, the isolation plate can reduce the upward loss of heat, improve the heat utilization rate, and allow the heat to be applied more concentratedly to the workpiece. The height-adjustable fixed frame and heating tube can accurately adjust the drying distance according to the size of the workpiece, optimizing the heating effect, achieving efficient use of energy, and reducing production costs.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a suspended conveying device for a painting workshop, including a support frame 1, a transmission conveying mechanism 2, an air drying mechanism 3 and a drying mechanism 4. The transmission conveying mechanism 2 is fixedly connected to the inner top wall of the support frame 1. The transmission conveying mechanism 2 includes a connecting frame 21 fixedly connected to the outer surface of the support frame 1. A transmission component 22 is fixedly connected inside the connecting frame 21.

[0029] The specific configuration and function of its transmission and conveying mechanism 2, air-drying mechanism 3 and drying mechanism 4 are described below.

[0030] In this embodiment: the transmission and conveying mechanism 2 includes a rotating hook 23 and a safety positioning column 24. The rotating hook 23 is threadedly connected to the transmission component 22, and the safety positioning column 24 is threadedly connected to the inside of the support frame 1. Bolts 25 are threadedly connected to both ends of the safety positioning column 24.

[0031] A connecting plate 26 is fixedly connected to the top of the rotating hook 23. A limiting ring 27 is fixedly connected to the top of the connecting plate 26. The limiting ring 27 is slidably connected to the outer surface of the safety positioning column 24. A sliding block 28 is fixedly connected to the top of the limiting ring 27. The sliding block 28 and the limiting ring 27 are symmetrically arranged inside the support frame 1.

[0032] The effects achieved by the above components are as follows: the rotating hook 23 is threadedly connected to the transmission component 22, so that the rotating hook 23 can move under the drive of the transmission component 22 to realize the suspension and transportation of the workpiece. The safety positioning column 24 is threadedly connected to the inside of the support frame 1 by bolts 25 at both ends, which plays a role in stabilizing the support, providing a positioning reference for the entire transmission and conveying process, ensuring the stability and safety of the transportation process, preventing the rotating hook 23 from shifting or shaking, and avoiding the workpiece from falling.

[0033] Specifically, a positioning plate 29 is fixedly connected to the bottom of the symmetrically arranged connecting plate 26, and an adjuster 210 is threadedly connected to both sides of the positioning plate 29. A clamping plate 211 is rotatably connected to the far end of the adjuster 210. The adjuster 210 and the clamping plate 211 are symmetrically arranged on both sides of the positioning plate 29.

[0034] The effect achieved by the above components is as follows: the positioning plate 29 at the bottom of the symmetrically arranged connecting plate 26 provides a mounting base for the adjuster 210 and the clamping plate 211. By rotating the adjuster 210, the position of the clamping plate 211 can be adjusted, thereby achieving clamping and fixing of workpieces of different sizes and shapes, improving the versatility of the suspension conveyor and adapting to the transportation needs of various coated workpieces.

[0035] Specifically, the transmission assembly 22 includes a first motor 221 fixedly connected inside the connecting frame 21. The output end of the first motor 221 is fixedly connected to a main rotating shaft 222. A rotating belt 223 is rotatably connected to the outer surface of the main rotating shaft 222. A secondary rotating shaft 224 is rotatably connected inside the rotating belt 223. The secondary rotating shaft 224 rotates synchronously with the main rotating shaft 222 under the drive of the rotating belt 223.

[0036] The effect achieved by the above components is as follows: the first motor 221 inside the connecting frame 21 serves as a power source, and the main rotating shaft 222 at its output end drives the rotating belt 223 to rotate. The rotating belt 223 then drives the rotating shaft 224 to rotate synchronously, forming a stable transmission system that provides power transmission for the entire transmission and conveying mechanism 2, ensuring that the rotating hook 23 can move continuously and stably.

[0037] Specifically, a rotating threaded rod 225 is fixedly connected to the outer surface of the main rotating shaft 222 and the secondary rotating shaft 224. A bearing 226 is rotatably connected to the far end of the rotating threaded rod 225. The outer surface of the bearing 226 is fitted into the interior of the support frame 1. A sliding block 28 is threadedly connected to the outer surface of the rotating threaded rod 225.

[0038] The effect achieved by the above components is as follows: the main rotating shaft 222 and the rotating threaded rod 225 on the outer surface of the driven rotating shaft 224 rotate under the drive of the main and driven rotating shaft 224. The sliding block 28 is threadedly connected to the outer surface of the rotating threaded rod 225, converting the rotational motion of the rotating threaded rod 225 into the linear motion of the sliding block 28, thereby driving the rotating hook 23 to move horizontally along the track inside the support frame 1, realizing the suspension and conveying of the workpiece.

[0039] Specifically, the drying mechanism 3 includes a fixed plate 31 fixedly connected to the top of the support frame 1. A second motor 32 is fixedly connected to the top of the fixed plate 31. A double-layer drying fan 33 is fixedly connected to the output end of the second motor 32. The double-layer drying fan 33 and the second motor 32 are symmetrically arranged on both sides of the support frame 1.

[0040] The effect achieved by the above components is as follows: the second motor 32 drives the double-layer drying fan 33 to rotate at high speed, generating a strong airflow. The symmetrically arranged double-layer drying fan 33 and the second motor 32 can perform all-round air drying of the workpiece during the suspension and conveying process from both sides of the support frame 1, quickly blow away excess paint or moisture on the surface of the workpiece, accelerate paint drying, improve coating efficiency and quality, and at the same time reduce paint dripping and waste.

[0041] Specifically, the drying mechanism 4 includes support columns 41 fixedly connected to the four corners of the bottom of the support frame 1. Threaded holes 42 are evenly spaced on the outer surface of the support columns 41. A fixing frame 43 is threadedly connected to the outer surface of the support columns 41. Limiting members 44 are threadedly connected to both sides of the fixing frame 43.

[0042] The effects achieved by the above components are as follows: the support columns 41 at the four corners of the bottom of the support frame 1 provide support for the entire drying mechanism 4; the setting of the threaded hole 42 allows the fixed frame 43 to be adjusted at different heights through the threaded connection to adapt to workpieces of different sizes and different drying requirements; the limiting member 44 is used to fix the fixed frame 43, ensuring that the fixed frame 43 is stable in position during the drying process and will not shake or shift.

[0043] Specifically, a heating tube 45 is fixedly connected inside the fixed frame 43, and an isolation plate 46 is snapped onto the top of the fixed frame 43. The fixed frame 43 and the heating tube 45 are threadedly connected to the outer surface of the support column 41 through a limiting member 44.

[0044] The effects achieved by the above components are as follows: the heating tube 45 inside the fixed frame 43 generates heat after being energized, which heats and dries the workpiece suspended above, promoting rapid curing of the coating. The isolation plate 46 is snapped onto the top of the fixed frame 43, which can prevent heat from being lost upwards, improve heat utilization, and at the same time prevent operators from accidentally coming into contact with high-temperature components, ensuring personnel safety.

[0045] Working principle: First, the first motor 221 is started, which drives the main rotating shaft 222 to rotate. The main rotating shaft 222 drives the driven rotating shaft 224 to rotate synchronously through the rotating belt 223. This causes the main rotating shaft 222 and the rotating threaded rod 225 on the outer surface of the driven rotating shaft 224 to rotate. The sliding block 28, which is threadedly connected to the rotating threaded rod 225, moves linearly along the rotating threaded rod 225 under the action of threaded transmission. This causes the rotating hook 23 to move back and forth on the track inside the support frame 1. The workpiece to be coated or already coated is fixed on the positioning plate 29 of the rotating hook 23 through the adjuster 210 and the clamping plate 211. As the rotating hook 23 moves, the workpiece enters the coating area for coating operation.

[0046] After the coating is completed, the workpiece continues to move with the rotating hook 23. The second motor 32 is started, and the second motor 32 drives the double-layer drying fan 33 to rotate. The airflow generated dries the surface of the workpiece, initially removing excess paint or moisture from the surface of the workpiece.

[0047] At this time, the heating tube 45 is energized and heats up to dry the workpiece, so that the coating can be cured quickly. By adjusting the position of the fixed frame 43 on the support column 41 and the fixing of the limiting part 44, the drying temperature and time can be adjusted according to the different needs of the workpiece to ensure the coating quality of the workpiece. Throughout the process, the safety positioning column 24, the limiting ring 27 and other components ensure the stability and safety of the rotating hook 23 and the movement of the workpiece, so as to realize the efficient and stable suspension, transportation and handling of the workpiece in the painting workshop.
