When the workpiece is cut, the driving gear 16 continues to rotate to drive the rectangular frame 17 to move right again, the rectangular frame 17 drives the conveyor belt 2 to rotate clockwise (the view angle in fig. 3), so that the cut workpiece at the right end of the conveyor belt 2 is driven to move right to roll off to realize discharging, and meanwhile, the next workpiece can be conveyed to the right end of the conveyor belt 2 to be cut; the rectangular frame 17 can also drive the movable rod 15 to move right, so as to drive the left end of the supporting piece 9 to swing downwards to realize unloading, and meanwhile, the rectangular frame is convenient for providing space for the next workpiece.

Example two

As shown in fig. 4, the difference between the present embodiment and the first embodiment is that a sealing box 19 is fixedly arranged on the frame 1 through bolts, a piston 20 is movably arranged in the sealing box 19 horizontally, a piston rod 21 is fixedly connected to the left end of the piston 20 in a clamping manner, and the piston rod 21 is fixedly connected to the rectangular frame 17 in a clamping manner. The piston 20 divides the seal box 19 into a first seal space 26 and a second seal space 27, the first seal space 26 is communicated with the first hose 22, the second seal space 27 is communicated with the second hose 23, and the position where the second hose 23 is communicated with the seal box 19 is positioned at the top of the seal box 19; as shown in fig. 5, a blowing hole 24 is formed in the supporting member 9, the upper end of the blowing hole 24 is obliquely arranged leftwards, so that the air flow blown out from the blowing hole 24 faces the cutting station of the cutting knife 8, the first hose 22 is clamped and fixed with the supporting member 9, and the first hose 22 is communicated with the blowing hole 24; the support 9 is further provided with a vent hole 25, the vent hole 25 is positioned on the right side wall of the accommodating cavity, and the second hose 23 is communicated with the vent hole 25.

In specific implementation, when the rectangular frame 17 moves to the right to drive the workpiece to move to the right, the piston 20 can also be driven to move to the right, the piston 20 moves to the right to form negative pressure in the first sealed space 26, and the first sealed space 26 sucks external air into the first sealed space 26 through the first hose 22.

After the work piece transported the cutting station, when rectangle frame 17 moved the return to the left, can drive piston 20 and move to the left, the gas in the first enclosure space 26 of extrusion, make the gas of first enclosure space 26 blow out through gas hole 24, thereby form the air current in gas hole 24 department, so at this moment, when cutting machine 7 moved down and cut the work piece, the air current near cutting station can be accelerated to the air current that blows out in gas hole 24 department, cool down the cutting part, thereby avoid cutting knife 8 and the condition that the high-speed friction of work piece leads to generating heat fast, can play the guard action to cutting knife 8, the life of extension cutting knife 8.

Simultaneously, rectangle frame 17 moves left and drives piston 20 when moving left, can also produce the negative pressure in second confined space 27 to form the negative pressure in air vent 25 department, so cutting machine 7 moves down when cutting the work piece this moment, and the sweeps and the dust that the cutting produced can drift to the right and hold the intracavity, and the negative pressure of air vent 25 department can be collected above-mentioned sweeps and dust, thereby has avoided the abominable condition of environment near the cutting station.
