Description

Technical Field

[0001] The utility model relates to a feeding mechanism, in particular to a feeding mechanism for a laser cutting machine, belonging to the technical field of laser cutting machines. Background Technique

[0002] A laser cutting machine emits laser from a laser generator, which is focused into a laser beam with a high power density through an optical path system. The laser beam irradiates the surface of a workpiece, causing the workpiece to reach the melting point or boiling point. As the relative position of the beam and the workpiece moves, finally a cut is formed in the material, thus achieving the purpose of cutting. Laser cutting uses an invisible beam to replace the traditional mechanical knife, with the characteristics of high precision, fast cutting, not limited by cutting pattern restrictions, automatic layout to save materials, smooth cut, and low processing cost, and will gradually improve or replace traditional cutting process equipment.

[0003] When a common laser cutting machine is working, its feeding structure generally first puts the fabric into the cutting machine, then cuts it, then takes out the cut fabric, and then puts in new fabric, and so on. Among them, when taking and placing the fabric, the cutting machine is in a stopped state, greatly reducing the utilization rate of the laser cutting machine, and thus resulting in a low cutting efficiency problem. Summary of the Invention

[0004] The purpose of the utility model is to provide a feeding mechanism for a laser cutting machine to solve the problem of low cutting efficiency of the laser cutting machine in the prior art.

[0005] The utility model is realized through the following technical solutions: A feeding mechanism for a laser cutting machine includes a bottom plate. An upper feeding device and a cutting device are installed on the upper surface of the bottom plate. The feeding mechanism includes a turntable. The turntable is located on the upper surface of the bottom plate and is rotationally connected to the bottom plate. A platform plate is placed above the turntable. Three groups of grooves arranged in a circular pattern are opened on the upper surface of the platform plate. The inner wall of each groove is slidably connected with a slider. Three gears are rotationally connected to the upper surface of the turntable. A rotating rod is fixedly connected to the upper surface of each gear. The other end of each rotating rod is fixedly connected with a disc. A plurality of rotating plates are hinged to the upper surface of each disc. The other end of each rotating plate is hinged to the slider close to it. A toothed ring is installed on the upper surface of the bottom plate, and the toothed ring meshes with the gear.

[0006] Preferably, a return spring is fixedly connected to the inner side surface of each slider, and the other end of each return spring is fixedly connected to the inner wall of the groove, which is beneficial to the stability of the return spring. The elastic force of the return spring can push the slider to reset, thereby releasing the clamping of the material.

[0007] Preferably, a driving motor is installed on the bottom surface of the bottom plate. The output end of the driving motor penetrates through the bottom plate, and the output end of the driving motor is fixedly connected to the turntable, which is beneficial to the stability of the driving motor. The output end of the driving motor can drive the turntable to rotate stably.

[0008] Preferably, the cutting device includes a vertical plate. A carrier plate is slidably connected to the side surface of the vertical plate. A laser device body is installed on the bottom surface of the carrier plate, which is beneficial to the stability of the laser device body and further maintains the overall stability.

[0009] Preferably, a plurality of support columns are fixedly connected to the bottom surface of the bottom plate, which is beneficial to the stability of the support columns. The support columns can maintain the overall stability.

[0010] Preferably, the toothed ring is a semi-toothed ring, and its teeth are only distributed on the left side of the toothed ring, which is beneficial to the stability of the toothed ring, so that the connection relationship between the gear and the toothed ring is in three stages: unmeshed - meshed - disengaged.

[0011] Preferably, a plurality of upright columns are fixedly connected to the upper surface of the turntable. The other end of each upright column is fixedly connected to the platform plate, which is beneficial to the stability of the platform plate and further maintains the overall stability.

[0012] The present utility model provides a loading mechanism for a laser cutting machine, and its beneficial effects are as follows:

[0013] In this loading mechanism for a laser cutting machine, by setting the sliders, the rotation of the disc can drive the sliders to approach each other and clamp the material block to be cut. At the same time, the sliders corresponding to the gears not meshed with the toothed ring are disengaged from the material, so that the material can complete the loading and unloading operations while being cut, solving the problem of low cutting efficiency of the laser cutting machine in the prior art.

[0014] In this loading mechanism for a laser cutting machine, by setting the return springs, when the gears meshed with the toothed ring are no longer in contact with the toothed ring, the sliders are reset under the pushing force of the return springs and automatically release the clamping of the material, facilitating the rapid replacement of the material.
