When the auxiliary plate moves to one side of the marking part, the auxiliary plate cooperates with the baffle to assist in fixing the marking part, and the marking part blocks the auxiliary plate. After the limit plate is blocked, it flips with the installation axis in the limit seat as the center of the circle, and resets after moving to the other side of the slider.

The harmful gas enters the air purification box, and the air purification box filters and purifies the harmful gas.

[0028] In summary, the present invention mainly has the following beneficial effects:

[0029] The present invention improves the heat dissipation effect of the marking head by providing an air collecting pipe, a heat dissipation pipe, an air purification box and a fan. The heat dissipation pipe runs through the marking head. When the marking head performs a marking operation, the heat dissipation pipe absorbs the heat generated by the internal components of the marking head and conducts it to the outer end of the marking head. The fan rotates continuously, so that the gas discharged from the air purification box is conducted to the air collecting pipe, enters into multiple groups of heat dissipation pipes through the air collecting pipe, and is discharged from the other end of the heat dissipation pipe, which accelerates the cooling effect of the heat dissipation pipe, improves the heat dissipation effect of the marking head during long-term marking operations, and further improves the metal marking processing efficiency.

[0048] See also Figure 3 - Figure 5 A first slide groove 24 and a second slide groove 27 are symmetrically provided at the upper end of the equipment body 1, and the lengths of the two groups of first slide grooves 24 are shorter than those of the two groups of second slide grooves 27.

[0049] See also Figure 2 - Figure 5 The upper mounting shafts of the two sets of limit seats 25 are sleeved with limit plates 23, and both ends of the two sets of mounting shafts are provided with torsion springs. One end of the two sets of limit plates 23 extends into the first slide groove 24, and one end of the two sets of limit plates 23 is movably connected with the two sets of sliders 29 respectively. The two sets of limit seats 25 are displaced, thereby driving the two sets of limit plates 23 to be displaced, and the two sets of limit plates push the two sets of sliders 29 to be displaced.

[0050] See also Figure 2 - Figure 5Auxiliary plates 28 are installed on the upper ends of the two groups of sliders 29, and the cross-sections of the two groups of sliders 29 are both inverted "T" shapes. A baffle 32 is installed on the upper end of the equipment body 1. The two groups of sliders 29 are displaced, thereby pushing the auxiliary plate 28 to displace. When the auxiliary plate 28 moves to one side of the marking part, the auxiliary plate 28 cooperates with the baffle 32 to assist in fixing the marking part, and the marking part blocks the auxiliary plate 28.

[0052] See also Figure 7 - Figure 8 The outer walls of the two groups of movable shafts 34 are sleeved with auxiliary belts 33, and one end of the auxiliary belt 33 extends to the outer wall of the baffle 32. One group of movable shafts 34 rotates, and the outer walls of the two groups of movable shafts 34 are sleeved with auxiliary belts 33. Therefore, the auxiliary belt 33 moves around the two groups of movable shafts 34, thereby driving the cylindrical marking part to rotate and adjust the marking area.

[0053] See also Figure 1 - Figure 3 An air intake plate 21 is installed at the upper end of the equipment body 1, and the air intake port of the air intake plate 21 faces the first slide slot 24.

The fan 31 rotates to generate suction at the air intake of the air purification box 10, and the air purification box 10 is connected to the air intake plate 21 through the air intake pipe 20. Therefore, the air intake plate 21 generates suction to absorb the harmful gas generated during the marking operation, and the harmful gas enters the air purification box 10, and the air purification box 10 filters and purifies the harmful gas.

[0054] The working principle of the present invention is as follows: when the operator uses the metal marking machine to mark the marking part, the operator places the marking part on one side of the baffle 32, and then drives the first limit shaft 3 to rotate through a set of turntables, and the outer wall of the first limit shaft 3 is threadedly connected to the inner wall of the mounting column 4, so the mounting column 4 is displaced, thereby driving the first transfer tube 13 to displace, and then driving the first telescopic tube 12 to stretch, and the second limit shaft 5 is driven to rotate through another set of turntables, and the outer wall of the second limit shaft 5 is threadedly connected to the inner wall of the mounting seat 6, so the mounting seat 6 is displaced, thereby driving the hydraulic pump 7 and the second transfer tube 15 to displace, and then driving the second telescopic tube 14 to stretch, and then completing the adjustment of the marking head 9, so that the marking head 9 suspends the upper end of the marking part;

[0055] When the marking head 9 is adjusted, the operator starts the driving motor 22 to drive a set of driving shafts 26 to rotate, and the two sets of driving shafts 26 are connected by a synchronous belt, so the two sets of driving shafts 26 rotate synchronously, and the inner walls of the two sets of limiting seats 25 are respectively threadedly connected with the outer walls of the two sets of driving shafts 26, so the two sets of limiting seats 25 are respectively displaced inside the two sets of second slide grooves 27, thereby driving the two sets of limiting plates 23 to displace, and one end of the two sets of limiting plates 23 extends into the two sets of first slide grooves 24, thereby pushing the two sets of sliders 29 to displace, and then pushing the auxiliary plate 28 to displace;

[0056] When the auxiliary plate 28 moves to one side of the marking part, the auxiliary plate 28 cooperates with the baffle 32 to assist in fixing the marking part, and the marking part blocks the auxiliary plate 28. After the limit plate 23 is blocked, it turns around the mounting axis in the limit seat 25 as the center of the circle, and resets after moving to the other side of the slider 29. Then, the limit seat 25 drives the limit plate 23 to continuously move toward the baffle 32.

[0057] When the limit plate 23 moves at the lower end of the marking part, the marking head 9 performs marking operation on the marking part, and the driving shaft 26 continues to rotate. A set of driving shafts 26 are connected to the linkage shaft 30 through a synchronous belt, so the linkage shaft 30 rotates, thereby driving the fan 31 to rotate, so that the air inlet of the air purification box 10 generates suction, and the air purification box 10 is connected to the suction plate 21 through the air inlet pipe 20, so the suction plate 21 generates suction to absorb the harmful gas generated during the marking operation, and the harmful gas enters the air purification box 10, and the air purification box 10 filters and purifies the harmful gas;

[0058] After the harmful gas is purified, the gas is discharged into the gas outlet pipe 11 through the air outlet of the air purification box 10, and sequentially passes through the first telescopic tube 12, the first transfer tube 13, the second telescopic tube 14, the second transfer tube 15 and the third telescopic tube 16, and enters the gas collecting pipe 17. The gas enters the multiple groups of heat dissipation pipes 19 through the gas collecting pipe 17. The multiple groups of heat dissipation pipes 19 absorb the heat generated when the marking head 9 is in operation. The gas is discharged through the heat dissipation pipes 19, which accelerates the cooling effect of the heat dissipation pipes 19 and further improves the heat dissipation effect of the marking head 9.

[0059] If marking operations need to be performed on multiple locations of the marking part, when the marking part is a rectangular body, the operator displaces the marking head 9 by rotating the first limit shaft 3 to adjust the marking position. If the marking part is a cylinder, the operator pulls the toothed plate 36 to displace it, and the toothed plate 36 and the movable gear 35 rotate, so the movable gear 35 rotates, thereby driving a group of movable shafts 34 to rotate. The outer walls of the two groups of movable shafts 34 are provided with auxiliary belts 33, so the auxiliary belts 33 are displaced around the two groups of movable shafts 34, thereby driving the cylindrical marking part to rotate and adjusting the marking area.

[0060] The present invention arranges an air collecting pipe 17, a heat dissipating pipe 19, an air purification box 10 and a fan 31. The fan 31 rotates so that the gas exhausted from the air purification box 10 is conducted to the air collecting pipe 17 and enters into a plurality of heat dissipating pipes 19 through the air collecting pipe 17, thereby accelerating the cooling of the heat dissipating pipes 19, improving the heat dissipation effect of the marking head 9 during long-term marking operations, and improving the metal marking processing efficiency.
