[0026] As Figures 1 to 8 shown, a waste slag suction device for a cutting machine comprises a slag suction structure 1 and a slag removal structure 2. The slag suction structure 1 comprises a support 11, a suction pipe 22 with a slag inlet 21, and a horizontal driving mechanism 23 for driving the horizontal movement of the suction pipe 22. The suction pipe 22 adopts a metal pipe structure, and an adjustable height supporting leg 100 is arranged at each foot of the bottom of the support 11. The horizontal driving mechanism 23 can adopt the structure of a motor driving a screw rod or a motor synchronous belt structure, which can be directly purchased from the market. A inclined block 220 is fixed at the slag inlet 21 in the suction pipe 22 by a screw, and the inclined surface 221 of the inclined block 220 faces the inner cavity of the suction pipe 22. The main advantages of this technical point are: 1. The waste slag splashed on the inclined block 220 will directly rebound into the inner cavity of the suction pipe 22, improving the efficiency of slag suction; 2. Since the waste slag of the prior art will frequently splash at the slag inlet 21, it is easy to cause pits or damage at the slag inlet 21, thereby requiring replacement of the entire suction pipe 22, while the technical solution of the present application is convenient to replace the inclined block 220, or the inclined block 220 can be taken out and ground flat.

[0027] The support 1 in the application is provided with a vertical driving mechanism 3 for driving the lifting of the horizontal driving mechanism 23; and the horizontal driving mechanism 23 is provided with a rotating mechanism 4 for driving the rotation of the suction pipe 22. The rotating mechanism comprises a first driving motor 41, a belt pulley 42 fixedly arranged on the suction pipe 22, and a belt assembly 43 connecting the first driving motor 41 and the belt pulley 42. At least two bearings 44 are fixed on the horizontal driving mechanism 23 by screws, and the suction pipe 22 passes through the inner ring of the bearings 44 and is fixedly connected with the inner ring of the bearings 44. The first driving motor 41 in the application adopts a servo motor, which can accurately control the rotation angle of the suction pipe 22 through program control.

[0028] The vertical driving mechanism 3 comprises a second driving motor 31, a transmission assembly 32 connected with the second driving motor 31, a screw rod 33, the screw rod 33 is connected with the transmission assembly 32 through screw connection, and a lifting block 34 connected with the horizontal driving mechanism 23 is arranged on the screw rod 33. The second driving motor 31 is a servo motor, the rotation of the second driving motor 31 can drive the screw rod 33 to move up and down, further drive the horizontal driving mechanism 23 to move up and down, and the vertical height of the suction pipe 22 can be accurately controlled in this way. Two vertical guide rails 35 are fixed on the support 11 through screws, and two sliding blocks 36 are respectively slidably connected on the vertical guide rails 35, the sliding blocks 36 are installed on the horizontal driving mechanism 23, and the horizontal driving mechanism 23 can move up and down more stably in this way, and shaking is avoided.

[0029] The vertical driving mechanism 3 in the application can automatically control the vertical movement of the suction pipe 22 through the automatic control system of the cutting machine, and the rotating mechanism 4 can automatically drive the rotation of the suction pipe 22, so that the suction pipe 22 can follow the movement of the cutting machine through the control of the control system, and the slag inlet 21 can follow the cut at any time, and the slag suction effect is improved.

[0030] The end of the suction pipe 22 away from the slag inlet 21 is connected with the slag removal structure 2 through a first pipe body 50, the slag removal structure 2 comprises a box body 51 and a fan 52 installed on the box body 51, the box body 51 is provided with an inlet 53 and an outlet 54, the inlet 53 is connected with the first pipe body 50, and the fan 52 is connected with the outlet 54 through a second pipe body 55. The box body 51 is a square box with an open front and a door body 500, and the door body 500 can be opened to clean the waste slag. The outlet 54 is provided with a filter 600 at one end in the box body 51, so that the fan 52 is prevented from being blocked.

[0031] Two vertical plates 61 are arranged in the inner cavity of the box body 51, the vertical plates 61 divide the inner cavity of the box body 51 into three chambers, and the three chambers are sequentially a first chamber 71, a second chamber 72 and a third chamber 73 from one communicating with the inlet 53 to one away from the inlet 53. A transverse filter screen is arranged in each chamber, and the three transverse filter screens are sequentially a first transverse filter screen 81, a second transverse filter screen 82 and a third transverse filter screen 83 from the first chamber 71 to the third chamber 73, the mesh size of the first transverse filter screen 81 to the third transverse filter screen 83 gradually decreases, the inlet 53 is located below the first transverse filter screen 81 in the application, and the outlet 54 is located above the third transverse filter screen 83.

[0032] A flow channel is provided inside the vertical plate 61. An air inlet 62 is located on the side of the vertical plate 61 facing the inlet 53, above the horizontal filter. An air outlet 63 is located on the side of the vertical plate 61 facing away from the inlet 53, below the horizontal filter. With this special design, the airflow sequence into the housing 51 is as follows: below the first chamber 71 → first horizontal filter 81 → above the first chamber 71 → flow channel of the vertical plate 61 → below the second chamber 72 → second horizontal filter 82 → above the second chamber 72 → flow channel of the vertical plate 61 → below the third chamber 73 → third horizontal filter 83 → above the third chamber 73 → outlet 54. As can be seen from the above airflow sequence, this design significantly increases the residence time of air within the housing 51.

[0033] In this invention, a fixed airflow channel is formed in the inner cavity of the housing 51. This design extends the residence time of air in the housing 51 without changing its volume. Under the action of gravity, the waste residue in the air will gradually settle at the bottom of the housing 51, improving the slag removal effect and effectively recycling the waste residue. The mesh size of the multiple horizontal filter screens gradually decreases from the one near the inlet to the one farther away from the inlet 53. This multi-stage filtration method improves the filtration effect and effectively prevents the horizontal filter screens from clogging too quickly, avoiding a reduction in the suction power of the fan due to clogging and improving the overall service life.

[0034] To facilitate the removal of waste residue from the housing 51, a receiving tray 80 is provided in each chamber below the transverse filter screen. A vibrator 90 is also provided on the transverse filter screen in this invention; this structure further reduces clogging of the transverse filter screen.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
