[0021] Reference Figure 1-4 A feeding device for a laser cutting machine comprises a laser cutting machine 1 and two sliding frames 3 symmetrically arranged on both sides of the laser cutting machine 1, a moving frame 2 is arranged on one side of the top of the laser cutting machine 1, two sliding rods slidably connected to the top of the adjacent sliding frames 3 are connected to both sides of the bottom of the moving frame 2, and an opening is arranged on the top of the moving frame 2;

[0022] A lifting assembly is provided at the top center of the mobile frame 2, and two adsorption plates 5 are symmetrically provided at the bottom. An adsorption cavity is provided inside the adsorption plate 5, and a plurality of adsorption pipe heads 8 connected to the interior of the adsorption cavity are connected to the bottom. A vacuum assembly is provided on one side of the two adsorption plates 5, one end of the vacuum assembly is connected to the interior of the two adsorption cavities, and the other end is used to connect with the vacuum equipment.

A plurality of conveying rollers 7 are provided at one end of the laser cutting machine 1 and located between the two sliding frames 3, and the two ends of the conveying rollers 7 are rotatably connected to the side walls of the adjacent sliding frames 3 respectively.

[0023] This program has the following working process:

[0024] When using this laser cutting machine feeding device, the staff first places the metal raw material to be cut on several conveying rollers 7. These conveying rollers 7 are located at one end of the laser cutting machine 1 and between the two sliding frames 3, which is convenient for the initial conveying and positioning of the raw materials. Subsequently, the metal raw material is smoothly fed to one end of the laser cutting machine 1 by the rotation of the conveying rollers 7. The mobile frame 2 is connected to the top of the sliding frame 3 on both sides by sliding rods at its bottom, ensuring that the mobile frame 2 can stably move above the laser cutting machine 1 and move to the top position of the raw material. Next, the lifting assembly adjusts the height of the adsorption plate 5 through the lifting structure so that the adsorption pipe head 8 contacts the top of the raw material, and the exhaust device is started. The adsorption cavity of the two adsorption plates 5 is vacuumed by the exhaust assembly, so that the adsorption pipe head 8 generates negative pressure, thereby tightly adsorbing the metal raw material on the adsorption plate 5, and then the raw material is moved to the processing position by the mobile frame 2, and then the raw material is put down by the lifting assembly, and finally the vacuum device is turned off, so that the raw material can be stably placed at the top processing position of the laser cutting machine 1. The entire workflow realizes the automated feeding and precise positioning of metal raw materials, greatly improving the efficiency and ease of operation of laser cutting.

[0025] According to the above working process, we can know that:

[0026] The feeding device of this laser cutting machine has significantly improved the overall efficiency and operational convenience of laser cutting operations through its ingenious design. First, by being equipped with a conveying roller 7, the device can easily realize the initial conveying and positioning of metal raw materials, avoiding the cumbersome and inefficient reliance on manual handling in the traditional way, thereby greatly saving manpower and material resources. Secondly, the sliding connection design between the mobile frame 2 and the sliding frame 3 ensures that the mobile frame 2 can move stably and flexibly above the laser cutting machine 1, providing a strong guarantee for the precise positioning of the raw materials. In addition, the combination of the adsorption plate 5 and the adsorption pipe head 8, coupled with the vacuum adsorption function of the vacuum assembly, can firmly fix the metal raw materials in place, effectively preventing the displacement of materials during the cutting process, thereby ensuring the accuracy and quality of the cutting. At the same time, the introduction of the lifting assembly and the lifting structure enables the device to be flexibly adjusted according to raw materials of different thicknesses and sizes, further broadening the scope of application of the device. In general, the feeding device of this laser cutting machine not only significantly reduces the labor intensity of workers through automated and precise operation, but also greatly improves the work efficiency and cutting quality of laser cutting, injecting new vitality into the modernization and efficient development of the metal cutting industry.

[0027] Furthermore, guide rods 9 are fixedly connected to both sides of the top of the adsorption plate 5, and the top end of the guide rods 9 penetrates the mobile frame 2 through the sliding sleeve. Specifically, through the arrangement of the guide rods 9 and the mobile frame 2, the guide rods 9 can stably slide up and down in the mobile frame 2, ensuring the stability and accuracy of the adsorption plate 5 during the lifting process, thereby ensuring that the raw materials can be accurately transported to the processing position of the laser cutting machine 1. Such a design improves the reliability and accuracy of the feeding device.

[0028] Furthermore, the side wall of the sliding frame 3 is fixedly connected to the side wall of the laser cutting machine 1 by bolts, and the bottom sides of the sliding frame 3 are fixedly connected with support rods 6. Specifically, the stability and firmness of the sliding frame 3 are ensured by the setting of the bolted connection between the sliding frame 3 and the laser cutting machine 1, which provides a solid support for the mobile frame 2 and the conveying roller 7. At the same time, the support rods 6 further enhance the stability of the entire device, making the feeding process more stable and reliable.

[0029] Furthermore, a slide groove is provided on the top of the sliding frame 3, and a push cylinder 4 is installed on one side of the inner part of the slide groove. The output end of the push cylinder 4 is connected to the side wall of the adjacent sliding rod. Specifically, the automatic movement of the mobile frame 2 on the sliding frame 3 is realized by the matching arrangement of the push cylinder 4 and the sliding rod. The push cylinder 4 can provide stable and controllable power, so that the mobile frame 2 can be accurately moved to the specified position, thereby improving the automation and efficiency of feeding.

[0030] Furthermore, the lifting assembly includes a cross bar 14 connected to the top center of the mobile frame 2 and a lifting cylinder 13 connected to the top center of the cross bar 14. The lifting structure includes a lifting bracket 10 connected to the output end of the lifting cylinder 13. The bottom sides of the lifting bracket 10 are fixedly connected with fixed rods. One end of the two fixed rods is connected to the top of the adjacent adsorption plate 5. Specifically, the smooth lifting and lowering of the adsorption plate 5 is achieved through the coordinated arrangement of the lifting cylinder 13, the lifting bracket 10 and the fixed rod. The lifting cylinder 13 provides power, and transmits the power to the adsorption plate 5 through the lifting bracket 10 and the fixed rod, so that it can be accurately lifted to the specified height, ensuring that the raw materials can be accurately placed at the processing position of the laser cutting machine 1.

[0031] Furthermore, the vacuum assembly includes a connecting pipe 12 and a connecting pipe 11. Both ends of the connecting pipe 12 are respectively connected to the two adsorption plates 5 and are connected to the adjacent adsorption cavities. The connecting pipe 11 is connected to one side of the connecting pipe 12. Specifically, an effective vacuum system is formed by the arrangement of the connecting pipe 12 and the connecting pipe 11. The connecting pipe 12 connects the adsorption cavities of the two adsorption plates 5, so that the vacuum equipment can vacuum the two adsorption cavities at the same time through the connecting pipe 11. Such a design simplifies the structure of the vacuum system and improves the vacuum efficiency, thereby ensuring that the raw materials can be firmly adsorbed on the adsorption plate 5 to prevent displacement during the cutting process.
