[0020]Such asFigure 1-8As shown, a portable iron sheet cutting machine, a portable iron sheet cutting machine, includes a hollow seat 1, characterized in that: a feed slot on the upper side of the inner wall of the hollow seat 1, and the upper end of the hollow seat 1 A column 2 is fixedly provided, a movable groove is provided on one side of the column 2, a through hole 63 is provided on a side wall of the movable groove away from the hollow seat 1, and the movable groove is close to a side of the hollow seat 1. A threaded rod 3 is rotatably arranged on the side wall, and a first rotating handle 4 is fixedly arranged at one end of the threaded rod 3 close to the through hole 63. A moving plate 5 is screwed on the threaded rod 3, and the moving plate 5 is far away One end of the column 2 is fixedly provided with a bracket 6, a first rotating shaft is rotatably arranged on the bracket 6, a circular saw blade 80 is fixedly arranged on the first rotating shaft, and a first rotating shaft is fixedly arranged on the first rotating shaft. A pulley 8, a second rotating shaft on the upper side of the first rotating shaft is rotatably arranged on the bracket 6, a second pulley 10 is fixedly arranged on the second rotating shaft, and one end of the second rotating shaft A second rotating handle 78 is fixedly arranged, a belt 11 is drivingly connected between the first pulley 8 and the second pulley 10, and a placing plate 50 is hinged on both sides of the top surface of the hollow seat 1 respectively.
[0021]Each placing board 50 is provided with a first cleaning device and a second cleaning device.
[0022]The first cleaning assembly includes a first cavity 200 arranged in the placing plate 50, and a reciprocating moving plate 51 is arranged in the first cavity 200, and the moving plate 51 is close to one end of the hollow seat 1. A push block 52 is hinged, and a torsion spring is fixedly arranged at the hinge of the push block 52. One end of the torsion spring is fixedly arranged on the push plate 52, and the other end is fixedly arranged on the shift plate 51. Two sliding grooves 566 are provided on the side wall of the placing board 50 near the moving block 51, which penetrate the side of the placing board 50 near the moving board 51, and a rod 52 is respectively provided in the two sliding grooves 566. The ends of the two supporting rods 52 close to the moving plate 51 are fixedly connected to the moving plate 51, and the ends of the two supporting rods 52 away from the moving plate 51 are connected by a pressing rod 53, and the pressing rod 53 is located in the placing plate 50.
[0023]The second cleaning assembly includes a second cavity 750 arranged in an end of the placing plate 50 close to the hollow seat 1, and a movable rod 760 that can seal and reciprocate is arranged in the first cavity 200. The movable rod A spring 752 is fixedly arranged between 760 and the side wall of the first cavity 200 close to the second cavity 750. One end of the second cavity 750 communicates with the first cavity 200 through an air outlet 777. The other end of the second cavity 750 penetrates the placing board 50 and is close to the side of the moving board 51. The second cavity 750 is provided with a reciprocating sliding block 754; the sliding block 754 can be positioned The iron filings on the top surface of the hollow seat are pushed down into the feeding trough, and at the same time, the push plates 52 on both sides can be pushed closer to the end of the hollow seat, so that the blade can be hidden between the two push plates 52 Therefore, it is possible to prevent the equipment from getting jammed due to bumps during transportation or because the circular saw blade is not placed upwards, allowing iron filings to enter the first rotating shaft, the second rotating shaft or the connection between the belt and the pulley. Therefore, it is convenient to carry the equipment, and it is more convenient to carry. It also avoids the need to clean up the iron filings on the placing board after each use. It only needs to be poured out when the hollow seat is full of iron filings. , Thereby saving manpower and improving work efficiency; the arrangement of the spring 752 can reduce the impact force when the lower end of the push plate 52 is in contact with the top surface of the fixing base, thereby avoiding the impact when the push plate 52 is in contact with the fixing base If the force is too strong, the push plate 52 is damaged, and when the metal sheet needs to be cut when the moving plate 51 is removed, the sliding block 754 can be returned to the second cavity so that there is no protruding part of the placing plate, so as to avoid Impact on iron cutting.
[0024]A rubber block 888 is fixedly arranged on the side of the push plate 52 close to the placing plate 50; the rubber block can be set to seal the feeding trough, and iron filings leak out from the feeding trough when placed in the handling equipment Need to be cleaned, causing unnecessary labor waste.
[0025]A supporting block 900 is fixedly arranged on both sides of the bracket 6 respectively; the two 50 can be fixed in the vertical direction by abutting the lower end of the supporting block 900 with the upper end of the moving plate 51.
[0026]A sponge strip 666 is fixedly arranged on both side walls of each chute; the arrangement of the sponge strips can prevent iron filings from entering the chute.
[0027]Working principle: Place the iron sheet on the placing plate 50, rotate the first rotary handle 4 and the second rotary handle 78 by hand, the first rotary handle will drive the threaded rod to rotate, and the threaded rod will drive the moving plate 5 to move downward. The second rotating handle drives the second belt wheel to rotate, the second belt wheel drives the first belt wheel to rotate, the first belt wheel drives the circular saw blade 80 to rotate, and the circular saw blade 80 that rotates down while rotating will cut the skin; When the equipment is used up for transportation, only one person needs to turn the placing plate 50 to the vertical direction by hand, and then rotate the first rotating handle by hand to move the circular saw blade downwards. The moving plate 51 will be under gravity. Move downwards under the action to push all the iron filings on the placing plate 50 into the feeding trough. At the same time, the moving plate 51 drives the pressing rod 53 to move toward the moving rod 760 through the pushing plate 52. When the pressing rod 53 When contacting the moving rod 760 and pushing the moving rod 760 to move, the volume between the moving rod 760 and the side wall of the first cavity close to the second cavity 750 becomes smaller and the air pressure increases, and the increased air pressure will push The sliding block 754 moves toward the side close to the push plate 52. When the sliding block 754 moves, it pushes the iron chips remaining on the upper surface of the hollow seat into the feed slot and also pushes the push plates 52 on both sides. Move closer.
