Description

Technical Field

[0001] The utility model relates to the technical field of spraying treatment, in particular to a suspension conveying device and a spraying system. Background Art

[0002] The production of aluminum alloy profiles can be divided into four processes: ingot preparation, extrusion molding, heat treatment and surface treatment. With the continuous improvement of people's living standards, the requirements for the appearance and color of doors and windows are getting higher and higher, and with the gradual refinement of aluminum processing technology, some complex surface treatments have been vigorously developed.

[0003] The coating spraying in the surface treatment process includes surface pretreatment, spraying, baking and curing. Specifically, the powder coating is sprayed on the surface of the workpiece with electrostatic powder spraying equipment. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powder coating. The powder coating is baked and leveled at high temperature to form a final coating with different effects. In the spraying process, a hanging conveyor chain is required to transport the aluminum alloy profiles.

[0004] A Chinese utility model patent with publication number CN212502365U discloses a suspended conveyor chain, which relates to the technical field of conveying. The key points of its technical solution are that it includes a track and a chain arranged in a ring shape, and a driving component is arranged on the track for driving the chain to move along the shape of the track.

[0005] However, the above-mentioned suspended conveyor chain drives the chain to move along the shape of the track through the driving component, and uses the chain to perform conveying and transmission actions at the same time. Since the weight of the baffle and the workpiece suspended on the hook is larger than the weight of the chain itself, the output torque of the driving component is larger.

[0039] The above-mentioned hanging conveying device performs conveying action to hang workpieces or profiles through the conveying chain 21, and performs transmission action by connecting with the conveying chain 21 through the transmission chain 33. During the conveying process, the conveying chain 21 mainly increases the supporting force by the rolling contact between the upper guide wheel unit 22 and the conveying bracket 1. The output torque of the transmission motor 31 only needs to drive the transmission chain 33 to move and provide the sliding friction force of the upper guide wheel unit 22, and it is not easy to get stuck.
