Description

Technical Field

[0001] The utility model relates to the technical field of blanking hoppers, in particular to a blanking hopper for a cutting machine. Background Art

[0002] With the development of the modern machining industry, requirements for cutting quality and precision continue to rise, along with the need for improved production efficiency, reduced production costs, and highly intelligent automated cutting capabilities. The development of CNC cutting machines must adapt to the demands of the modern machining industry. Cutting machines are categorized as flame cutting machines, plasma cutting machines, laser cutting machines, and water jet cutting machines. Laser cutting machines are the most efficient, offer the highest cutting accuracy, and generally cut smaller thicknesses. Plasma cutting machines also offer high cutting speeds and can cut surfaces with a certain degree of slope. Flame cutting machines are ideal for thicker carbon steel materials.

[0003] According to a disclosed material quantity controllable hopper for a laser cutting machine (publication number: CN 212793622U), it includes a material guide frame and a material control cover. The material control cover is fixed to the top of the material guide frame, and adjustment screws are threadedly connected on both sides of the material control cover. Draft fans are installed on both sides of the material guide frame below the material control cover. Adjustment plates are provided on both sides of the interior of the material guide frame. Adjustment springs are fixed to the surface of one end of the adjustment plate at equal intervals, and the end of the adjustment spring away from the adjustment plate is fixedly connected to the inner wall of the connecting block. The surface of the adjustment plate away from the connecting block is hinged with an extension rod. The surface of the extension rod inside the material guide frame is sleeved with a telescopic spring. A control button is installed on the surface of the material guide frame. This utility model not only improves the practicality of the hopper and avoids the phenomenon of material piling up at the discharge port, but also avoids the phenomenon of excessive dust when the hopper is used, which may harm the health of workers.

[0004] In the above application, only a single material discharge path can be achieved through the cooperation of components such as the material guide frame and the material control cover. When the material discharge rate is too high, blockage is likely to occur, which needs to be improved. Utility Model Content

[0028] As mentioned above, a torsion spring 49 is fixedly connected to the side surface of the discharge plate 48 , and one end of the torsion spring 49 is fixedly connected to one end of the discharge port 47 .

[0029] As mentioned above, the diameter of the push rod 45 is larger than the diameter of the discharge port 47 , and one side of the discharge plate 48 is located on the displacement track of the push rod 45 .

[0030] As mentioned above, a plurality of notches are provided on the top of the blanking inclined plate 2 .

[0031] Working principle: When unloading is required, one side of the base plate 1 is aligned with the unloading port of the cutting machine body, and the material discharged from the cutting machine body falls to the top of the base plate 1. At this time, the motor 42 is started to drive the reciprocating screw 43 to rotate. The reciprocating screw 43 rotates, driving the internal threaded sleeve 44 to move horizontally back and forth under the restriction of the limit rod 46, and then drives the push rod 45 to move horizontally back and forth. The push rod 45 moves horizontally back and forth to push the material on the top of the base plate 1 to the discharge port 47. The material is pushed and squeezed on one side of the discharge plate 48, driving the discharge plate 48 to rotate, and then opening the discharge port 47 for unloading.

[0032] A lifting mechanism 5 is provided on one end of the reciprocating screw rod 43, and the lifting mechanism 5 includes a half gear 51. One end of the half gear 51 is fixedly connected to one end of the reciprocating screw rod 43, and the top of the baffle 3 is fixedly connected to a slide plate 52. The side of the slide plate 52 is slidably connected to a connecting rod 53. One end of the connecting rod 53 is fixedly connected to a rack plate 54, and the bottom of the rack plate 54 is fixedly connected to a lifting plate 55.

The clockwise rotation of the half gear 51 drives the rack plate 54 to slide intermittently from right to left. The rack plate 54 slides from right to left, driving the ejector plate 55 to slide intermittently from right to left. The ejector plate 55 slides from right to left to push the material that the ejector rod 45 at the top of the bottom plate 1 cannot push to the displacement track of the ejector rod 45. When the teeth of the half gear 51 cannot contact the teeth at the top of the rack plate 54, the connecting rod 5 The ejector plate 55 is reset by the elastic action of the reset spring 56. During the reset process, the ejector plate 55 is rotated counterclockwise by the material blocking limit plate 58, so that the material passes through one side of the ejector plate 55 and reaches the side where the ejector plate 55 is to push the material next time. When the ejector plate 55 works next time, the staff only needs to rotate the block 59 to block the side of the ejector plate 55 so that the material no longer pushes the ejector plate 55 to rotate during the pushing process, and the material pushing work can be completed.
