Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, and in particular to a material feeding limiting device for a plasma cutting machine. Background Technology

[0002] Plasma arc cutting machines are machines that use plasma cutting technology to process metal materials. Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to melt the metal part or part of the workpiece at the cut, and uses the momentum of high-speed plasma to remove the molten metal to form a cut.

[0003] Chinese utility model patent CN218016339U discloses an automatic feeding device for a plasma cutter. This device, through a servo motor, worm gear, and other mechanisms, can adjust the tilt angle of the feeding plate to allow the cut material to be stacked layer by layer in a transport vehicle. However, in actual use, this device has certain drawbacks. For example, the material slides freely during its descent, and adjusting the tilt angle only affects the material's path, failing to precisely control the landing point, leading to misalignment or irregular stacking. Therefore, this invention proposes a feeding limit device for a plasma cutter to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a material feeding limit device for a plasma cutting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plasma cutting machine unloading limiting device includes an unloading frame, an unloading plate rotatably connected to the inner wall of the unloading frame, and sliding grooves on both outer walls of the unloading plate. A baffle is provided at the upper end of the groove opening. A threaded rod is rotatably connected to the inner wall of the unloading plate, and a slider is threadedly connected to the threaded section of the threaded rod. Two sets of guide plates are fixedly connected to the lower end of the slider. The upper half of the two sets of guide plates is inclined outward, and there is a certain gap between the two sets of guide plates and the end face of the unloading plate. A rotating mechanism for driving the unloading plate to tilt is installed on the side wall of the unloading frame.

[0007] Preferably, the rotating mechanism includes multiple sets of side plates and slide rods, with the multiple sets of side plates symmetrically installed in pairs on the back of the feed plate, and slide rods fixedly connected between each pair of side plates.

[0008] Preferably, an electric telescopic rod is rotatably connected to the inner walls on both sides of the unloading rack, and an adjusting block is rotatably connected to the telescopic end of the electric telescopic rod, with the adjusting block slidably connected to the outer wall of the sliding rod.

[0009] Preferably, the end face of the slide bar is in close contact with the feeding plate, and a limit rod is fixedly connected to the inner wall of the feeding plate.

[0010] Preferably, the slider is slidably connected to the outer wall of the limiting rod, and the guide plate is slidably connected to the groove.

[0011] Preferably, a servo motor is fixedly connected to the side wall of the feeding plate, and the end of the output shaft of the servo motor is fixedly connected to the threaded rod coaxially.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses a servo motor to drive the threaded rod to rotate, which in turn drives the slider to slide, thereby adjusting the position of the guide plate, guiding and restricting the material's downward path. The guide plate effectively reduces unstable factors during the material's downward slide, ensuring that the material slides accurately along the set path, and avoiding misalignment and irregular stacking caused by free sliding.

[0014] 2. This utility model uses an electric telescopic rod to drive the adjusting block to slide, which in turn drives the feeding plate to rotate around the hinge point of the feeding frame, thereby precisely adjusting the tilt angle of the feeding plate. By adjusting the tilt angle, the landing point of the material can be better controlled, ensuring that the material is accurately piled in the predetermined position, avoiding uncontrollable factors that may occur during the material's descent, and improving the accuracy and stability of feeding.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3A plasma cutting machine material feeding limiting device includes a feeding frame 1, a feeding plate 2 rotatably connected to the inner wall of the feeding frame 1, and grooves 3 on both outer walls of the feeding plate 2. A baffle is provided at the upper end of the groove opening of the groove 3. A threaded rod 4 is rotatably connected to the inner wall of the feeding plate 2, and a slider 6 is threadedly connected to the threaded section of the threaded rod 4. Two sets of guide plates 12 are fixedly connected to the lower end of the slider 6. The upper half of both sets of guide plates 12 is inclined outwards, and there is a certain gap between the two sets of guide plates 12 and the end face of the feeding plate 2. A rotating mechanism for driving the feeding plate 2 to tilt is installed on the side wall of the feeding frame 1. The guide plates 12 can effectively guide the sliding material to fall along a predetermined path, while the rotation of the threaded rod 4 can drive the guide plates 12 to slide horizontally, thereby reducing instability factors during the material's descent and improving the accuracy of the material's landing point.

[0021] The rotating mechanism includes multiple sets of side plates 9 and slide rods 10. The multiple sets of side plates 9 are symmetrically installed in pairs on the back of the feed plate 2. Slide rods 10 are fixedly connected between the two side plates 9. Electric telescopic rods 8 are rotatably connected to the inner walls of both sides of the feed rack 1. Adjusting blocks 11 are rotatably connected to the telescopic ends of the electric telescopic rods 8. The adjusting blocks 11 are slidably connected to the outer wall of the slide rods 10. The end face of the slide rods 10 is in close contact with the feed plate 2. Limiting rods 5 are fixedly connected to the inner wall of the feed plate 2. By means of the telescopic extension and retraction of the telescopic ends of the electric telescopic rods 8, the adjusting blocks 11 are driven to slide on the outer wall of the slide rods 10. During the sliding process, the adjusting blocks 11 drive the feed plate 2 to rotate around the hinge point with the feed rack 1, thereby adjusting the tilt angle of the feed plate 2.

[0022] The slider 6 is slidably connected to the outer wall of the limiting rod 5, the guide plate 12 is slidably connected to the slide groove 3, and the servo motor 7 is fixedly connected to the side wall of the feeding plate 2. The end of the output shaft of the servo motor 7 is coaxially fixedly connected to the threaded rod 4.

[0023] In this invention, the device is used as follows: the unloading rack 1 is placed at the unloading port of the cutting machine, and then the servo motor 7 is started to drive the threaded rod 4 to rotate. The rotation of the servo motor 7 drives the threaded rod 4 to rotate, thereby driving the slider 6 to slide along the threaded section of the threaded rod 4. As the slider 6 slides, the two sets of guide plates 12 slide horizontally. During the material unloading process, the position of the guide plates 12 driven by the servo motor 7 can guide the material to slide down along a predetermined path, thereby improving the accuracy of the material sliding process and avoiding unstable sliding factors.

[0024] Meanwhile, the landing point of the material can be further controlled by the operation of the electric telescopic rod 8. The telescopic drive adjustment block 11 of the electric telescopic rod 8 slides on the outer wall of the slide rod 10. When sliding, it drives the feeding plate 2 to rotate around the hinge point of the feeding frame 1. Through this process, the tilt angle of the feeding plate 2 is adjusted to ensure that the feeding plate 2 can adjust its tilt angle as needed to better control the landing point of the material. This device guides the material through the guide plate 12 and adjusts the angle of the feeding plate 2. The material can slide on the feeding plate 2 along the specified path, reducing the possible misalignment or irregular stacking of the material during the sliding process.

[0025] Through the above process, the material feeding limit device of the plasma cutting machine can effectively solve the problems of unstable material sliding and irregular stacking, realize precise material feeding and stacking process, and improve production efficiency and operational stability.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
