Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal production equipment, and particularly relates to an automatic conveying device for spraying. Background Art

[0002] Sheet metal parts are often used in automobiles, electronic products, and furniture. To ensure stable performance during the production process, sheet metal parts require a protective coating applied via a spray coating process after processing. To improve spray coating quality and efficiency, automated spray coating conveyors have emerged. Traditional spray coating operations largely rely on manual labor, which is not only inefficient but also difficult to ensure consistent coating quality. With technological advancements, automated spray coating conveyors have become increasingly mainstream, enabling automated workpiece transport, thereby improving the efficiency and quality of spray coating operations.

[0003] When suspending workpieces, traditional spraying devices cannot adapt to workpieces of different sizes and shapes due to the fixed suspension points. The conveying track is set to a ring shape. For example, Chinese patent application number CN201820281370.0, published on January 4, 2019, discloses a conveyor line for sheet metal spraying, including a spraying workshop and a fixed frame. Two track grooves are symmetrically fixed on both sides of the fixed frame. The same

[0004] The two ends of the track groove are fixed with a driving motor, and the output end of the driving motor passes through the track groove and is connected to the driving wheel; a plurality of guide wheels are respectively provided in the two symmetrically installed track grooves; the two symmetrically installed track grooves extend from one end of the driving motor to the spraying workshop, and a driven wheel is fixed to one end of the track groove extending to the spraying workshop; the driving wheels, guide wheels and driven wheels in the two track grooves are connected by a conveyor belt, and the conveyor belts in the two track grooves are fixed by a column

[0005] The utility model is easy to operate, simplifies the equipment structure and reduces the maintenance cost of the equipment.

[0006] The above arrangement requires that multiple guide wheels be arranged in the annular slide, and then hangers be arranged on the multiple guide wheels. However, since the multiple hangers are arranged in parallel at intervals in the length direction of the annular track, it cannot be ensured that the number of sheet metal parts sprayed each time is the same as the number of sheet metal parts arranged on the spacing between the two slide rails. In addition, since the two relatively arranged pulleys need to keep rotating synchronously, otherwise they are likely to get stuck at the turning position of the annular slide rail, which makes the transportation unstable and leads to the problem of low production efficiency of sheet metal spraying. Utility Model Content

[0007] The purpose of the utility model is to provide an automatic conveying device for spraying, which enables sheet metal parts to move more reliably on an annular slide rail and has high production efficiency.

[0010] With the above settings, the driving device is started, and the material rack is driven by the driving device to slide on the conveying track. The pulley slides on the conveying track, driving the entire material rack mechanism to move along the conveying track. When the first-level beam moves to the curved section of the annular slide rail, the first-level beam is rotatably connected to the lower end of the second-level beam, and the sliding wheel is rotatably connected to the first-level beam, so that the upper end of the first-level beam is rotatably set relative to the curved section, and the lower end of the first-level beam is rotatably set relative to the second-level beam, so that the first-level beam can move relative to the curved section, thereby ensuring that the material rack mechanism has enough sheet metal parts to be sprayed, and can ensure more reliable movement in the curved section, and since a second-level beam is provided, it can ensure that more sheet metal parts can be set on the transversely moving second-level beam for spraying operations, thereby improving production efficiency.

[0011] Furthermore, the hanging assembly includes a hanger, a hanging plate and a hanging hole, the hanger is rotatably connected to the lower shaft, the hanging plate is threadedly connected to the lower end of the lower shaft through a bolt, and the hanging hole is opened at the side end of the hanging plate.

[0012] The above arrangement can conveniently hang the sheet metal parts to be sprayed on the hanging assembly.

[0013] Furthermore, the material rack mechanism includes two primary hanging beams, one secondary hanging beam and a hanger, the length of the two primary hanging beams is less than the length of one secondary hanging beam, and the length of one primary hanging beam is less than the straight length of the curved section of the conveying track.

[0014] The above arrangement can more reliably ensure that the first-level hanging beam can reliably and smoothly turn and slide on the annular sliding track.

[0015] Furthermore, the pulley is made of wear-resistant material.

[0016] The above arrangement increases the service life of the pulley.

[0017] Furthermore, a mounting hole is provided at the lower end of the secondary suspension beam, a first mounting hole is provided on the hanger, a thread is provided at the lower end of the lower shaft, a mounting platform is provided at the upper end of the lower shaft, the width of the mounting platform is greater than the width of the mounting hole, and the lower end of the lower shaft is matched with the mounting hole and the first mounting hole.

[0019] Furthermore, a reinforcement frame is fixedly connected to the side end of the conveying track.

[0020] The above arrangement can increase the strength of the conveying track.

[0021] Furthermore, an upwardly concave slide groove is provided on the conveying track, and the driving mechanism includes a driving motor, a driving wheel and a driving chain. The driving motor is fixed to the side of the conveying track, the driving motor is fixedly connected to the driving wheel, and the driving wheel is rotationally connected to the driving chain.

[0022] The above arrangement drives the driving wheel to rotate by the driving motor and then drives the chain to move, and then drives the pulley to move. BRIEF DESCRIPTION OF THE DRAWINGS
