[0039] The utility model discloses a cutting table, which comprises an annular air duct and a plurality of air suction blocks, wherein the annular air duct is divided into an inner wall, a main air duct and an outer wall, a dust collector interface is arranged on the outer wall, a smoke outlet is arranged on the inner wall, a movable plug plate for adjusting the smoke outlet area is covered on the smoke outlet, and the movable plug plate is fixed to the inner wall through a fastening device; the side wall is connected with the inner wall to form an air suction block, the air suction block comprises the side wall and a platform arranged inside the air suction block, and a plurality of air suction ports are arranged inside the air suction block, the platform comprises the platform side wall and is hollow, and the smoke outlet is connected with the platform; the air suction area of ​​the air suction port is adjusted, thereby controlling the air suction volume of the air suction block, making the air suction volume of the air suction block of the entire cutting table roughly equal, achieving the effect of smoke and dust removal, thereby ensuring that the environment is not polluted by smoke and dust and the health of operators.

[0040] See also Figure 1 and Figure 2The utility model discloses a cutting table 100, which includes an annular air duct 10 and four air suction blocks 20. The annular air duct 10 is a hollow annular arrangement, which includes an inner wall 12, a main air duct 13 and an outer wall 14, and the radius of the inner wall 12 is r. A dust collector interface 11 is provided on the outer wall 14, and a smoke outlet 121 is provided on the inner wall 12, wherein the smoke outlet 121 on the inner wall 12 is determined according to the number of the air suction blocks 20, so Figure 1 There are 4 smoke outlets 121, and the smoke outlets 121 are located within the boundary between the air suction block 20 and the inner wall 12. The number of air suction blocks is not limited to 4, and the range is between 1-12. The air suction block 20 includes a shift plate 21, a cylindrical air suction port 22, a first side air suction port 23, a second side air suction port 24, and a platform 25. The air suction block 20 is fan-shaped, including two straight side walls 201 connected to each other and arc-shaped walls 202 respectively connected to the two straight side walls 201, wherein the platform 25 is arranged inside the air suction block 20 and is hollow, and is connected to the smoke outlet 121; the cylindrical air suction port 22 is arranged on the platform 25, the first side air suction port 23 is arranged on the platform side wall 251 of the platform 25, and the second side air suction port 24 is arranged on the two straight side walls 201 of the air suction block 20. In this embodiment, there is one dust collector interface 11. In the actual production process, multiple interfaces can be set according to actual conditions, not limited to one.

[0041] It should be further explained that the movable plate 21 is set to move up and down, and the size of the air suction port is adjusted by moving the movable plate 21 up and down. It includes a movable plug plate 211 and a fastener 212. The movable plug plate 211 is fixed to the inner wall 12 of the annular air duct 10 by the fastener 212, and the fastener 212 can adjust the tightness to adjust the height and position of the movable plug plate 211. The movable plug plate 211 controls the opening size of the smoke outlet 121 by adjusting the height. Controlling the opening size of the smoke outlet 121 affects the air suction volume of different suction blocks 20. Figure 1 It can be seen that the air volume of the smoke outlet 121 closer to the dust collector interface 11 is larger, and the air volume of the air suction block 20 farther away from the dust collector interface 11 is smaller. In the actual dust removal process, in order to suck away the smoke at each position, the air volume of each air suction block 20 should be similar, so the opening of the smoke outlet 121 close to the dust collector interface 11 along the inner wall of the main air duct is the smallest, and the smoke outlet 121 farthest from the dust collector interface 11 is the largest.

[0042] See further Figure 3 , Figure 3It is a partial enlarged view of the movable plate 211 and the smoke outlet 121, wherein the movable plate 211 has a movable plate lower edge 2111, and the smoke outlet 121 has a smoke outlet 121 lower edge 1211. The air suction volume of the air suction block 20 can be adjusted by adjusting the height H between the lower edge 2111 of the movable plate 211 and the lower edge 1211 of the smoke outlet 121. Figure 1 and Figure 2 The intersection point of the center line of each suction block 20 and the inner wall 12 is point A, and the intersection point of the diagonal line of the smoke outlet 121 is point D.

[0043] The distance between point A and point D along the circumference of the annular air duct 10 is S, and the arc length of the arc wall is L. The height between the lower edge 2111 of the movable plate in the suction block 20 and the lower edge 121 of the smoke outlet is a first height H1; the height between the lower edge 2111 of the movable plate in the suction block 20 and the lower edge 121 of the smoke outlet is a second height H2, wherein the first height H1 is between one-half and four-fifths of the second height H2; The height between the lower edge 2111 of the movable plate in the air suction block 20 and the lower edge 121 of the smoke outlet is a third height H3, wherein the third height H3 is not less than two-thirds of the second height H2. By setting the height between the lower edge 2111 of the movable plate 211 in the air suction block 20 and the lower edge 1211 of the smoke outlet 121 at different positions, that is, the height setting of the movable plate 211 covering the smoke outlet 12, the air suction volume of each air suction block 20 is ensured to be substantially the same.

[0044] A cylindrical air suction port 22 is provided on the platform 25 of each air suction block 20, a first side air suction port 23 is provided on each of the two platform side walls 251 of the platform 25, and a second side air suction port 24 is provided on each of the two straight side walls 201 of the air suction block 20. Figure 4 The circular air suction port 22 includes a locking device 221, a cylindrical shield 222, a circular cover 223, a column 224 and a cylindrical base 225. The cylindrical shield 222 is sleeved on the cylindrical base 225 and fixed by the locking device 221. The cylindrical base 225 is hollow for the convenience of smoke and dust discharge. One end of the column 224 stands on the cylindrical base 225 at intervals around the circumference of the cylindrical base 225, and the other end of the column 224 is connected to the circular cover 223. The cylindrical shield 222 is a movable setting, and different heights are adjusted by the locking device 221, so as to block the air outlet of the cylindrical air suction port 22 and control the air suction volume. The circular cover 223 can block the cutting waste from being sucked into the air duct.

[0045] The first side air suction port 23 is disposed on the platform side wall 251 of the platform 25. The first side air suction port 23 includes a baffle 231. One side of the baffle 231 is connected to the platform side wall 251. The angle between the baffle 231 and the first side air suction port 23 is between 0 and 120 degrees, preferably between 0 and 90 degrees, more preferably between 30 and 90 degrees, and even more preferably between 30 and 60 degrees. Thus, the baffle 231 can block the waste from being sucked into the annular air duct 10 during the cutting process. In addition, the baffle 231 can be movably arranged to adjust the air volume of the first side air suction port 23. The second side air suction port 24 is disposed on the straight side wall 201 of the air suction block 20. Please refer to the attached figure for further information. Figure 5 The second side air suction port 24 includes a sliding cover plate 241 and a track 242, wherein the sliding cover plate 241 is stuck in the track 242 and the sliding cover plate 241 is used to cover the opening of the second side air suction port 24 to control the air suction amount.

[0046] See also Figure 6 A cross-shaped lifting mechanism 30 is arranged with the center of the material table 100 as the center. The cross-shaped lifting mechanism 30 is telescopic, so that heads of different sizes can be fixed, which is convenient for cutting with a cutting gun. The cross-shaped lifting mechanism 30 includes four telescopic rods 31, wherein the length of the telescopic rods 31 of the cross-shaped lifting mechanism 30 is less than the radius r.

[0047] The cutting table disclosed by the utility model divides the suction area into a plurality of suction blocks, and sets a plurality of suction ports at different positions of the suction blocks, and the area of ​​each suction port is adjustable, so as to control the suction volume of each suction block, so that the smoke and dust at each position in the table can be sucked out, ensuring that the operating environment is not polluted and the health of the operator is ensured. The whole smoke and dust removal process is to open the dust collector, form negative pressure in the whole cutting table, and suck the smoke and dust in the cutting process into the main air duct through each suction port, and then suck it into the dust collector through the smoke outlet to achieve smoke and dust removal.

[0048] In addition, the spacing between the dragging teeth in the dragging tooth mechanism described in the utility model can be adjusted, so that it can serve as a hole-opening workbench for heads of different sizes. The heads can be randomly placed on the cutting workbench, and the cutting gun mechanism automatically locates the heads through an intelligent algorithm and automatically opens and cuts the heads. It can be seen that the head cutting device of the utility model has a high degree of intelligence and does not require manual intervention. The entire process of edge-opening and feeding and discharging is more automated, which not only saves labor costs, but also greatly improves cutting accuracy through cutting with the cutting gun mechanism, improves the intelligence of the head cutting process, and meets industrial production needs.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
