[0017] The collecting box 7 can be moved to the bottom of the processing position of the CNC machine tool by the moving wheel 4, and then the position of the seat body 1 can be limited by the limiting mechanism 22 to ensure the stability of the collecting box 7. Before the CNC machine tool processes the workpiece, the height of the collecting box 7 can be adjusted by the lifting mechanism 2 so that the protective plates 14 are located on both sides of the workpiece, and then the movable frame 17 can be driven to move by the telescopic member 3 18. The protective plates 14 in the movable frame 17 can move together until the ends of the protective plates 14 are connected to each other. The connected protective plates 14 can play a shielding role on the workpiece, and the CNC machine tool can process the workpiece. The waste splashed around during cutting can be blocked by the protective plate 14 and fall between the rotating rollers 12, making the waste collection process safer. The rotating rollers 12 can crush the fluffy cutting waste, which can effectively reduce the space occupied by the waste. The crushed waste can fall to the bottom of the collection box 7 along the gap between the fixed plates 21, and then the waste at the bottom of the collection box 7 can be squeezed by the squeezing mechanism 11, further reducing the space occupied by the waste. The waste is finally squeezed into blocks, which is not only convenient for removal, but also convenient for subsequent processing and transportation, and the use effect is better.

[0018] As an embodiment of the present invention, please refer to Figure 1 The lifting mechanism 2 includes a fixed cylinder 5 arranged on the outer wall of the base body 1, and a movable column 6 is movably arranged in the fixed cylinder 5, and the end of the movable column 6 is connected to the outer wall of the collecting box 7.

[0019] As an embodiment of the present invention, please refer to Figure 2 and Figure 4 The limiting mechanism 22 includes a telescopic member 23 that penetrates and is fixedly arranged at the four corners of the outer wall of the seat body 1. The specific structure of the telescopic member 23 is not limited. In this embodiment, preferably, the telescopic member 23 adopts a hydraulic cylinder, and a movable plate 24 is provided at the telescopic end of the telescopic member 23. A movable rod 25 is penetrated through the outer wall of the movable plate 24, and a baffle 26 is provided at one end of the movable rod 25, and a stop plate 28 is provided at the other end of the movable rod 25, and an elastic member 27 is sleeved on the outer wall of the movable rod 25.

[0020] As an embodiment of the present invention, please refer to Figure 3The extrusion mechanism 11 includes a telescopic member 28 that is fixedly arranged on the inner wall of one side of the collection box 7. The specific structure of the telescopic member 28 is not limited.

The outer wall of the movable plate 31 is penetrated by a mounting rod 34, one end of the mounting rod 34 is provided with a stopper 33, and the other end of the mounting rod 34 is provided with an extrusion cover 10. The outer wall of the mounting rod 34 is sleeved with an elastic member 235. The specific structure of the elastic member 235 is not limited.

The extrusion force can be monitored by the pressure sensor 36 to prevent the equipment from being damaged due to excessive extrusion force.

[0021] As an embodiment of the present invention, please refer to Figure 1 and Figure 3 The outer wall of the movable plate 31 is provided with a distance sensor 32, and the inner wall of the collection box 7 is provided with a distance receiver 9 matched with the distance sensor 32. The distance sensor 32 can emit infrared rays, which can then be received by the distance receiver 9, so as to achieve the purpose of monitoring the moving position of the extrusion cover 10, and when the pressure sensor 36 can monitor the pressure value, the pressure value can reflect the extrusion force, and the appropriate extrusion force value is inversely proportional to the moving distance of the extrusion cover 10, so that when there are more waste materials in the collection box 7, the extrusion force is greater, and the extrusion effect is better.

[0022] As an embodiment of the present invention, telescopic member 1 3, telescopic member 2 8, telescopic member 3 18 and telescopic member 4 23 are all connected to a controller via wires, and the distance receiver 9, pressure sensor 36 and touch switch 29 are electrically connected to the controller.

When the protective plate 14 moves toward the middle, the moving block 19 at the end of the protective plate 14 will contact the fixed block 20, and cause the protective plate 14 to be lifted up, so that the guide plate 15 on the inner wall of the protective plate 14 can pass over the rotating roller 12, and the end of the guide plate 15 is moved between the rotating rollers 12. Under the guiding action of the guide plate 15, the waste can better enter the gap between the rotating rollers 12, and the use effect is better.

[0024] When in use, the collection box 7 can be moved to the bottom of the processing position of the CNC machine tool through the moving wheel 4, and then the position of the base body 1 can be limited by the limiting mechanism 22 to ensure the stability of the collection box 7. Before the CNC machine tool processes the workpiece, the height of the collection box 7 can be adjusted by the lifting mechanism 2 so that the protective plates 14 are located on both sides of the workpiece, and then the movable frame 17 can be driven to move by the telescopic member 3 18. The protective plates 14 in the movable frame 17 can move together until the ends of the protective plates 14 are connected to each other. The connected protective plates 14 can play a shielding role on the workpiece, and the CNC machine tool can be used for processing the workpiece. The waste splashed around when the workpiece is cut can be blocked by the protective plate 14 and fall between the rotating rollers 12, making the waste collection process safer. The rotating rollers 12 can crush the fluffy cutting waste, which can effectively reduce the space occupied by the waste. The crushed waste can fall to the bottom of the collection box 7 along the gap between the fixed plates 21, and then the waste at the bottom of the collection box 7 can be squeezed by the squeezing mechanism 11, further reducing the space occupied by the waste. The waste is finally squeezed into blocks, which is not only convenient for removal, but also convenient for subsequent processing and transportation, and the use effect is better.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
