Description

Technical Field

[0001] The utility model relates to the technical field of loading machines, and particularly relates to a loading device for a metal sheet trimming machine. Background Art

[0002] An iron sheet barrel is a common container in life, which has the advantages of high strength and good sealing performance, and can be used as the basic packaging for liquid products such as paint, coating, and engine oil. The production process of an iron sheet barrel generally includes production processes such as barrel body cutting, barrel lid stamping, composite ring stamping, curling, spot welding, seam welding, ring ribs, flanging, necking, pipe rolling, edge rolling, dot ladder hands, hoop body cutting, hoop ear spot welding, handle spot welding, fitting assembly, closure spot welding, and final assembly inspection.

[0003] Before the barrel body plate of the iron sheet barrel is rounded, it needs to be trimmed by a trimming machine to ensure that after curling, the height of the barrel body is neat. In the existing loading device of the trimming machine, when loading, the material tray is simply placed on the roller frame, and the tray is sent to the lifting frame through the roller, and the material tray is lifted to the feeding position through the lifting frame. Since the position of the material tray is directly placed, there is often an error with the actual feeding position. Therefore, the trimming machine needs to adjust the position before trimming work can be carried out. When the position deviation is large, the trimming machine cannot fully adjust, so it is necessary to lower the material again and then use a forklift to re-adjust the position of the tray, which is not only inefficient but also troublesome to adjust, and there is room for further improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a loading device for a metal sheet trimming machine, which solves the above problems.

[0005] To achieve the above purpose, a loading device for a metal sheet trimming machine is provided, including a roller frame base, a lifting bracket, and a chain drive box. The top of the bracket is fixedly connected with a chain drive box. An electric roller frame is fixedly connected above one end of the roller frame base away from the lifting bracket. A plurality of independent roller supports are fixedly connected at equal intervals above one end of the roller frame base close to the lifting bracket. Both sides of the two ends of the bottom of the chain drive box are drivingly connected with lifting chains. The chain drive box is drivingly connected with a grid lifting seat through four lifting chains below.

[0006] A grid sliding seat is horizontally slidably connected above the grid lifting seat. A lead screw fixing plate is fixedly connected to the upper edge of the middle part of one side of the grid lifting seat. A bearing seat is fixedly connected above the lead screw fixing plate. An adjusting lead screw is rotatably connected above the bearing seat through a bearing. A lead screw nut is fixedly connected to the position corresponding to the bearing seat on the side of the grid sliding seat close to the lead screw fixing plate. The side of the adjusting lead screw away from the lead screw nut passes through the bearing seat and is fixedly connected with a handwheel.

[0007] According to the feeding device of the metal sheet trimming machine, the end of the adjusting screw away from the hand wheel passes through the screw nut and cooperates with the screw nut thread.

[0008] According to the feeding device of the metal sheet trimming machine, the bottom of the chain driving box is connected to the corresponding lifting chain through a sprocket.

[0009] According to the feeding device of the metal sheet trimming machine, support rollers are rotatably connected above the plurality of independent roller supports.

[0010] According to the feeding device of the metal sheet trimming machine, the grid spacing between the grid lifting seat and the grid sliding seat is the same as the spacing between the multiple independent roller supports.

[0011] According to the feeding device of the metal sheet trimming machine, connecting pins perpendicular to the grid lifting seat are fixedly connected above the four corners of the grid lifting seat, and one end of the four lifting chains close to the grid lifting seat is fixedly connected to the four corners of the grid lifting seat through the connecting pins perpendicular to the grid lifting seat.

[0012] The above solution has at least one of the following beneficial effects:

[0013] The utility model is provided with a grid lifting seat and a grid sliding seat, which cooperate with an adjusting screw and a screw nut.
