Except for the front side edge, the other three sides of the pallet 7 are provided with limiting edges 8, so that the polyurethane block can be loaded from the front side of the pallet 7, and the position is positioned by the limiting edges 8 on the other three sides; a mounting frame 10 is fixedly installed on the outside of the pallet 7; guide rods 9 are fixedly installed on both sides of the mounting frame 10, and the guide rods 9 are slidably installed with the cutting machine 1; a connecting rod 11 is slidably installed on the top of the mounting frame 10; an extrusion plate 13 is fixedly installed on the bottom of the connecting rod 11, and the extrusion plate 13 can contact the polyurethane block; a reset spring 12 is sleeved on the connecting rod 11, and the two ends of the reset spring 12 are respectively fixed to the mounting frame 10 and the extrusion plate 13.

[0021] See also Figure 2-Figure 3 The control component includes: a mounting plate 2, a servo motor 3, a screw rod 4, a movable block 5, a connecting plate 6 and a rotating shaft 601; the mounting plate 2 is fixedly mounted on the cutting machine 1; the servo motor 3 is fixedly mounted on the cutting machine 1; the screw rod 4 is rotatably mounted on the mounting plate 2, and the screw rod 4 is fixed to the output shaft of the servo motor 3; the rotating shaft 601 is rotatably mounted on the rear side of the bottom of the support plate 7; the connecting plate 6 is rotatably mounted on the bottom of the support plate 7 through the rotating shaft 601; the movable block 5 is rotatably mounted on the end of the connecting plate 6 away from the rotating shaft 601, and the movable block 5 is threadedly connected to the screw rod 4.

[0022] First, slide the extrusion plate 13 upwards to push the polyurethane block onto the support plate 7 from front to back, and the limiting edge 8 plays a limiting and prompting role. After the polyurethane block is against the limiting edge 8, stop moving the support plate 7, then relax the extrusion plate 13, and the return spring 12 clamps the polyurethane block on the support plate 7 through the extrusion plate 13; then start the cutting machine 1, control the moving seat 101 to move right, and cut the polyurethane block. After completion, the blade 102 passes through the polyurethane block and moves to the right side of the polyurethane block, start the servo motor 3, the servo motor 3 controls the screw rod 4 to rotate, and the screw rod 4 controls the movable block 5 to move backward, so that the front end of the connecting plate 6 moves backward, and the angle between the connecting plate 6 and the horizontal line is changed, so that the support plate 7, the mounting frame 10 and the components thereon move upward as a whole, so that the blade 102 can move downward relative to the polyurethane block, and the blade 102 moves down the cutting line of the polyurethane block. After that, the moving seat 101 moves left to cut out the next polyurethane energy-saving board. Therefore, it is only necessary to change the frequency of the intermittent rotation of the servo motor 3 according to the reciprocating movement frequency of the moving seat 101 to realize the automatic cutting of the cutting device.

[0023] During the entire cutting process, the return spring 12 can press the polyurethane block through the extrusion plate 13, and press the cut polyurethane energy-saving board onto the polyurethane block. Even if the blade 102 is in the polyurethane block, the return spring 12 can also adapt to the change, combined with the friction between the polyurethane energy-saving boards, the polyurethane energy-saving boards are not easy to scatter and detach, and their positions are stable, so that the cut polyurethane energy-saving boards do not affect the subsequent cutting process of the polyurethane blocks, and the polyurethane energy-saving boards can be neatly stacked for easy collection.

[0025] See also Figure 5 , further comprising: a control rod 15; a control rod 15 is fixedly mounted on the extrusion plate 13, and the use of the control rod 15 can more conveniently move the extrusion plate 13, thereby facilitating the loading of the polyurethane block.

[0026] See also Figure 1 , and also includes: a lifting rod 16; a lifting rod 16 is fixedly installed between the support plate 7 and the cutting machine 1, and the lifting rod 16 is used to enclose the space between the support plate 7 and the cutting machine 1 to prevent debris from accidentally entering the space between the support plate 7 and the cutting machine 1 when the support plate 7 moves up and down, thereby preventing the cutting of the polyurethane block from being affected and preventing people from being accidentally touched and injured.
