Cutting platform for roller type laser cutting machine

Abstract

The invention relates to a cutting platform for a roller type laser cutting machine. The cutting platform comprises a platform main body, a conveying mechanism and a smoke exhausting pipe. The cuttingplatform can achieve the purpose of continuous feeding and discharging of a whole roll of plate for the cutting platform, since plate conveying is achieved through support wheel rotation, the conditions that according to an original rolling cutting platform, a cut workpiece with a hole can be hung on supporting strips or a strip-shaped workpiece is clamped between upper and lower supporting strips, consequently the cutting platform cannot run, and the problem of damage occurs can be prevented; the smoke exhausting pipe can be closer to the plate processed by the cutting machine, so that the smoke suction and exhausting effects are better, the transmission efficiency is higher, and the stability is better, so that high-speed conveying of the plate can be realized; and a frequency conversion controller and a servo can be used for control, and cooperation with an unwinding leveler is achieved, so that automatic control is improved, and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cutting machines, in particular to a cutting platform for a roller-type laser cutting machine. Background technique [0002] With the improvement of the localization rate of laser cutters, laser cutting machines are more and more used by the majority of users. During the process of cutting plates by laser cutting machines, the cutting platform is responsible for the time of loading and unloading, the utilization rate of plates, and the collection of cutting dust. The impact of the laser cutting machine has gradually become prominent. Now the laser cutting machines on the market are mainly equipped with the following structural forms of cutting platforms, fixed cutting platforms, exchangeable cutting platforms and rolling cutting platforms, but the cutting platforms of these structural forms There are the following problems: [0003] 1. Fixed cutting platform. The laser cutting machine can only process fi...

Problems solved by technology

[0003] 1. Fixed cutting platform. The laser cutting machine can only process fixed-size plates, and cannot cooperate with the uncoiler to realize continuous cutting and processing of the entire roll of plates. The plates cut by the laser cutting machine must be unloaded before re-placement of the plates to be processed. Serious waste of time and low efficiency;

[0004] 2. The exchangeable cutting platform has a complex structure, and can only process fixed-size plates, and cannot cooperate with the uncoiler to realize continuous cutting and processing of the entire roll of plates. When the laser cutting machine is cutting, it can realize a cutting platform for plate cutting. Another cutting platform is used for unloading and loading. Although it can save some loading and unloading time, due to the limitation of its mechanism, the distance between the cutting plate and the smoke exhaust pipe will be far away, which makes the smoke exhaust effect extremely poor;

[0005] 3. Due to the problems existing in the fixed and exchangeable cutting platforms, a rolling cutting platform has emerged. Its structure is to use the chain to drive the plate support bar to roll in circles. When the laser cutting machine is cutting, it can realize the continuous cutting of the whole roll of plate. Loading and unloading saves loading and unloading time, but the number of support bars used by the rolling cutting platform is very large and the weight is very heavy, resulting in low transmission efficiency and slow transmission speed, and the finished workpiece with holes will appear Hanging on the support bar or the bar-shaped workpiece is stuck in the middle of the upper and lower support bars, etc., which will cause the cutting platform to fail to operate or even be damaged. At the same time, there is also the problem that the distance between the cutting plate and the smoke exhaust pipe is far away, and the smoke exhaust effect is poor.
