Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a feeding device for a laser cutting machine. Background Technology

[0002] Laser cutting technology is a key technology in modern industrial manufacturing. As the manufacturing industry moves towards higher precision, higher efficiency, and greater intelligence, laser cutting is gradually emerging with its unique advantages.

[0003] Traditional cutting methods, such as mechanical cutting, have many limitations in terms of cutting precision, cutting speed, and the ability to cut complex shapes. Laser cutting technology, on the other hand, uses a high-energy-density laser beam to irradiate the workpiece surface, causing the material to melt or vaporize instantly, thus achieving the cutting purpose. Laser cutting has advantages such as non-contact processing, narrow kerf, small heat-affected zone, high cutting precision, and high cutting speed, and is widely used in many industries such as metal processing, automotive manufacturing, and aerospace.

[0004] However, existing laser cutting machines still face some problems in practical use. One prominent issue is the difficulty in stably clamping the sheet metal during cutting. Unstable clamping directly leads to displacement or shaking of the sheet metal during cutting, resulting in inconsistent cutting quality and affecting the overall cutting effect. This has become a limiting factor for further improving the performance and application range of laser cutting machines. Utility Model Content

[0005] Based on the above-mentioned problems in the existing technology, the purpose of this utility model embodiment is to provide a feeding device for a laser cutting machine, which facilitates stable clamping of the material plate in conjunction with the laser cutting machine and avoids the material plate shaking during laser cutting.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a feeding device for a laser cutting machine, including a pressing component and a rotating component;

[0007] The pressing assembly includes a pressing rod, two rotating rods and a pressing strip. A groove is provided on one side of the pressing rod, and the pressing strip is slidably installed in the groove. One end of each of the two rotating rods is fixed perpendicularly to the pressing rod, and an annular tube is provided on the rotating rod.

[0008] The rotating assembly includes a rotating shaft and two fixed platforms, with each of the two ports of the rotating shaft inserted into one of the fixed platforms.

[0009] The rotating shaft passes through the annular tube.

[0010] Furthermore, the pressing assembly includes a bridging rod, which is arranged parallel to the pressing rod, and the end of the rotating rod away from the pressing rod is fixedly connected to the bridging rod.

[0011] Furthermore, the pressure assembly includes a plurality of screws;

[0012] The pressure rod has multiple through holes on the side away from the slide groove;

[0013] The pressure bar has multiple threaded holes.

[0014] The screw passes through the through hole and engages with the threaded hole.

[0015] Furthermore, an embedded groove is provided on the side of the pressure strip away from the threaded hole, and the pressure assembly includes a rubber strip, which is embedded in the embedded groove.

[0016] Furthermore, it includes a drive assembly, which comprises a fixed frame, a lead screw, and a connecting plate;

[0017] The fixing frame spans one side of the bridging rod, and the top of the fixing frame has two threaded holes;

[0018] The lead screw engages in the second threaded hole, and the end of the lead screw facing the inside of the fixed frame is rotatably connected to a bridge plate, and the bridge plate is provided with a second crossbar.

[0019] Each end of the connecting plate is provided with a sleeve, and one of the sleeves is fitted onto the second crossbar;

[0020] The bridging rod is provided with a crossbar, and the other sleeve of the connecting plate is fitted onto the crossbar.

[0021] Furthermore, a roller is provided at the end of the lead screw away from the bridge plate.

[0022] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0023] 1. The rotating wheel drives the lead screw to rotate, and the lead screw meshes with the second threaded hole. Therefore, it moves vertically when rotating. It drives the connecting plate to move up and down through the bridge plate and the second crossbar. The connecting plate drives the bridge rod to rotate around the position of the rotating shaft. The rotating rod drives the pressure rod to rotate. When the pressure rod moves upward, the sheet material can be loaded. That is, the sheet material is placed on the table of the laser cutting machine, and the edge of the sheet material is placed under the pressure rod. When the pressure rod moves downward, the sheet material is pressed. The pressure rod drives the rubber strip to press the sheet material through the pressure strip, which not only improves the pressing efficiency, but also avoids damage to the surface of the sheet material.

[0024] 2. The added screws ensure that the pressure strip is stably installed in the pressure rod, which can help stabilize and tighten the plate. After removing the screws, the pressure strip and the rubber strip inside the pressure strip can be quickly replaced, which facilitates the replacement of old and new rubber strips.

[0045] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0046] Please see Figure 1-4 The present invention provides a technical solution: a feeding device for a laser cutting machine, comprising a pressing component 1, a rotating component 2 and a driving component 3.

[0047] The pressure assembly 1 includes a pressure rod 11, two rotating rods 12, a bridging rod 13, a pressure strip 14, a rubber strip 15, and multiple screws 16.

[0048] A groove 1102 is provided on one side of the pressure rod 11, and multiple through holes 1101 are provided on the side of the pressure rod 11 away from the groove 1102.

[0049] One end of each of the two rotating rods 12 is fixed perpendicularly to the pressure rod 11, and an annular tube 1201 is provided on the rotating rod 12.

[0050] The bridging rod 13 is arranged parallel to the pressure rod 11, and the end of the rotating rod 12 away from the pressure rod 11 is fixedly connected to the bridging rod 13. A crossbar 131 is provided on the bridging rod 13.

[0051] The pressure strip 14 is slidably installed in the slide groove 1102. The pressure strip 14 has multiple threaded holes 1401. The side of the pressure strip 14 away from the threaded holes 1401 has an embedded groove 1402.

[0052] The rubber strip 15 is embedded in the inner groove 1402.

[0053] Screw 16 passes through through hole 1101 and engages with threaded hole 1401.

[0054] The rotating assembly 2 includes a rotating shaft 21 and two fixed platforms 22.

[0055] The two ports of the rotating shaft 21 are respectively inserted into one of the fixed platforms 22, and the rotating shaft 21 passes through the annular tube 1201.

[0056] The drive assembly 3 includes a fixed frame 31, a lead screw 32, and a connecting plate 33.

[0057] The fixing frame 31 is mounted across one side of the bridging rod 13, and the top of the fixing frame 31 has a threaded hole 3101.

[0058] The lead screw 32 is engaged in the threaded hole 3101, and the end of the lead screw 32 facing the inside of the fixed frame 31 is rotatably connected to the bridge plate 321. The bridge plate 321 is provided with a crossbar 322, and the end of the lead screw 32 away from the bridge plate 321 is provided with a wheel 323.
