Description

Technical Field

[0001] This utility model relates to the technical field of laser cutting machine components, and in particular to a chain conveyor system. Background Technology

[0002] The chain conveyor system is a new type of worktable for laser cutting machines that provides multi-point support for sheet metal. Utility model patent CN204094322U, which discloses a gantry-type laser cutting machine with an automatic continuous loading and unloading worktable, describes such a worktable. The worktable includes a support base and a sprocket and chain mechanism mounted on the support base. The sprocket and chain mechanism includes a motor-driven drive shaft mounted on the support base, two drive sprockets fixedly connected to the drive shaft, a driven shaft mounted on the support base, and two driven chains fixedly connected to the driven shaft. Drive sprockets one and two driven sprockets one are connected by a chain, and drive sprockets two and two driven sprockets two are connected by a chain. A toothed plate connects chain one and chain two. However, the worktable has the following disadvantages: Disadvantage 1: The bottom of the toothed plate is closed, which makes it impossible to leak the metal residue generated by laser cutting, increasing the difficulty of recycling and cleaning the metal residue; Disadvantage 2: Chain 1 and Chain 2 are essentially flexible components, and it is inevitable that deflection deformation will occur between the drive sprocket and the driven sprocket, which will affect the overall flatness of the worktable and the cutting accuracy of the laser cutting machine.

The difference is that the frame 1 is also provided with two longitudinal lower support rails 13. The lower support rails 13 are located directly below the lower part of the chain 6 and are connected to the lower part of the chain 6. The chain 6 has a slack side and a tight side. Generally, the slack side of the chain 6 is the lower part of the chain 6, and the tight side of the chain 6 is the upper part of the chain 6.
