Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a roller-supported platform type laser cutting machine. Background Technology

[0002] Laser cutting machines select different types of support platforms depending on the materials being processed. For products with low surface appearance requirements, a serrated support platform is generally used. However, for products with high appearance requirements, a serrated support platform can scratch the surface, so rollers are needed for support. In current roller support platforms, the rollers are directly mounted on the frame, and the rollers are driven by a gearbox. If a roller on one of the rollers malfunctions and needs repair, disassembly is inconvenient and time-consuming. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a roller-supported platform laser cutting machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A roller-supported platform type laser cutting machine includes a frame, a support platform mechanism, and a laser cutting mechanism mounted on the frame. The laser cutting mechanism includes an XYZ three-axis drive module and a laser cutting head mounted on the power output end of the XYZ three-axis drive module. The support platform mechanism includes a drive unit, several sets of roller assemblies, and a transmission chain. The roller assembly includes a mounting shaft, a bearing seat, a positioning bushing, a support disc, and a double sprocket. Two bearing seats are provided and mounted on the frame in a front-to-back arrangement. The two ends of the mounting shaft are rotatably connected to the two bearing seats. Several positioning bushings are provided. The positioning bushings are sleeved on the mounting shaft and fixed to the mounting shaft by set screws. The mounting shaft is mounted on a shaft; the number of supporting discs is one less than that of the positioning bushings; the supporting discs are fitted onto the mounting shaft and are respectively located between two adjacent positioning bushings, and are limited by contact with the positioning bushings on both sides; the double sprocket is fixed to one end of the mounting shaft; several transmission chains are provided; the power output end of the drive device is connected to a set of external teeth of the double sprocket of the right roller assembly through a transmission chain, and the other set of external teeth of the double sprocket is connected to the double sprocket of the left roller assembly through another transmission chain; the remaining transmission chains are sequentially connected between two adjacent sets of double sprockets until they are connected to the double sprocket of the leftmost roller assembly.

[0006] In a further description of this utility model, the supporting discs in the two adjacent sets of roller assemblies are arranged in a staggered manner.

[0007] In a further description of this utility model, the double sprocket is disposed on the front side of the rear shaft seat and is fixed to the mounting shaft by a keyway.

[0008] In a further description of this utility model, the driving device includes a geared motor and a drive gear; the geared motor is installed inside the frame and its power output end is connected to the drive gear.

[0009] The beneficial effects of this utility model are as follows:

[0010] This design uses an installation shaft to drive support discs to support and transport the product, ensuring that the product is not scratched. When some support discs are damaged after long-term use and need to be replaced or maintained, simply remove the two transmission chains connected to the roller assembly, insert the shaft seat, and the installation shaft can be taken out and positioned. After removal, the positioning bushing can be disassembled and the support discs can be taken out. The disassembly and assembly are convenient and facilitate equipment maintenance.
