Technical Field

The invention relates to the technical field of automation equipment, in particular to a drag chain rolling device, a drag chain mechanism and equipment.

Background

The drag chain is generally composed of a plurality of unit chains, and the plurality of unit chains can rotate randomly in advance. The drag chain is generally applied to reciprocating occasions and can play a role in dragging and protecting built-in cables, oil pipes, air pipes, water pipes and the like. Drag chains have been widely used in a variety of industries such as numerical control machines, laser cutting, electronic equipment, handling machines, plastic machines, lifting equipment, automotive industry, industrial vehicles, metal working machines, machine tools, and port equipment.

Generally, the drag chain is composed of a plurality of mutually hinged chain links, a fixed end seat and a movable end seat are arranged on the chain links at the two ends of the tail, and the chain links can flexibly rotate. The chain links are internally provided with channels for accommodating the working pipelines, so that a plurality of chain links form a belt-shaped cavity for accommodating the working pipelines.

Fig. 1 shows an automation device in the prior art configured with a conventional drag chain. In a linear motion scene, the wider surface of the drag chain contacts the bearing surface, and the movable end seat moves under the matching of the power mechanism and the guide rail. Because the chain links forming the drag chain have certain bending radius, certain requirements are put on the installation space. For example, as shown in fig. 1, the installation space required for installing the drag chain 200 must be greater than the height V1 of the drag chain 200 to ensure the proper operation of the drag chain 200.

Meanwhile, if the drag chain 200 having a flat shape is vertically mounted on the support plate (i.e., the support plate is in contact with a side end surface in a direction perpendicular to the paper surface in fig. 1), friction occurs between the side portions of the links and the support plate, resulting in a short service life of the drag chain 200. Finally, debris dust generated by the drag chain 200 in the prior art due to abrasion during movement also causes environmental pollution, which is not suitable in Clean rooms (Clean Room) required for semiconductor, microelectronic, and display panel manufacturing.

In view of the above, there is a need for an improved towline in the prior art to solve the above problems.
