[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution: a plasma cutting machine that is convenient for unloading, comprising a base plate 1, a cutting machine frame 2 and a material table 3 are provided on the base plate 1, a material plate 4 is placed on the material table 3, the material table 3 comprises an adjustment base 31, a first positioning platform 32, a second positioning platform 33 and a unloading mechanism 35, the lower ends of the first positioning platform 32 and the second positioning platform 33 are both provided with a driving frame 34, the unloading mechanism 35 comprises two groups of slides 351, an elastic layer 352 is provided between the two groups of slides 351, a slide groove 341 is opened on the driving frame 34, and the slide 351 is slidably connected to the slide groove 341.

[0025] The adjustment base 31 can adjust the positions of the first positioning platform 32 and the second positioning platform 33. According to the size specifications of the material plate 4, the distance between the first positioning platform 32 and the second positioning platform 33 can be adjusted accordingly by adjusting the base 31 so that the position of the first positioning platform 32 and the second positioning platform 33 can be adapted to the material plate 4.

[0026] like Figure 2 As shown, the adjusted first positioning platform 32 and second positioning platform 33 can support the material sheet 4, and both sides of the material sheet 4 are placed on the first positioning platform 32 and the second positioning platform 33 respectively, and there is no obstruction below the area to be cut of the material sheet 4.

[0027] The elastic layer 352 of the unloading mechanism 35 has a certain elastic force and is soft and stretchable. When the positions of the first positioning platform 32 and the second positioning platform 33 are adjusted, the elastic layer 352 relies on its own elastic force to produce corresponding elastic deformation to adapt to the position changes of the first positioning platform 32 and the second positioning platform 33. The position of the elastic layer 352 is always located below the material plate 4.

[0028] After the material sheet 4 is placed, it is cut by the cutting frame 2, and the cut finished material falls onto the elastic layer 352. The multiple groups of finished materials are collected together by the elastic layer 352, and the remaining materials are left on the positioning table, realizing automatic separation between the remaining materials and the finished materials. There is no need for subsequent sorting, and the material unloading is convenient, saving time and effort.

[0029] Among them, a motor 311 is installed on one side surface of the adjustment base 31, the motor 311 is connected to the bidirectional screw rod 312, the output shaft of the motor 311 and the bidirectional screw rod 312 are fixedly connected by a coupling, a slide rod 313 is provided on one side of the bidirectional screw rod 312, and two groups of slides 314 are provided on the slide rod 313 and the bidirectional screw rod 312, and the two groups of slides 314 are fixedly connected to the driving frame 34 at the lower end of the first positioning platform 32 and the driving frame 34 at the lower end of the second positioning platform 33 respectively, and the bidirectional screw rod 312 includes two groups of thread groove structures with opposite rotation directions.

[0030] When the motor 311 is working, it drives the bidirectional screw rod 312 to rotate, and then drives the two groups of slides 314 to slide along the slide rod 313, driving the two groups of slides 314 to move closer to or away from each other, and the two groups of slides 314 respectively drive the driving frame 34 fixed thereto to move synchronously, that is, when the motor 311 is working, it drives the first positioning platform 32 and the second positioning platform 33 to move closer to or away from each other, and by controlling the rotation direction and number of rotations of the motor 311, the distance between the first positioning platform 32 and the second positioning platform 33 can be flexibly adjusted.

[0031] The first positioning platform 32 and the second positioning platform 33 are both provided with a plurality of groups of negative pressure adsorption holes 331 , and the plurality of groups of negative pressure adsorption holes 331 are evenly spaced along the straight direction of the positioning platform.

[0032] The first positioning platform 32 and the second positioning platform 33 are connected via a negative pressure hose 36 .

[0033] The negative pressure hose 36 is connected to the negative pressure pump assembly.

[0034] When the negative pressure pump assembly is working, the negative pressure hose 36 generates a negative pressure suction force, so that the multiple groups of negative pressure adsorption holes 331 at the upper ends of the first positioning platform 32 and the second positioning platform 33 generate a negative pressure adsorption force. The negative pressure adsorption force is used to adsorb and fix the material sheet 4, thereby improving the stability of the material sheet 4, preventing the material sheet 4 from being displaced during the cutting process, and improving the cutting accuracy.

[0035] Among them, handles 353 are welded and fixed at both ends of the slide plate 351. Applying a certain external force to the handles 353 can pull the unloading mechanism 35, which facilitates the unloading of the finished material after the cutting is completed.

[0036] The cutting machine frame 2 includes a first electric slide 21 and a second electric slide 22 . The first electric slide 21 is provided in two groups, and the second electric slide 22 is mounted between the two groups of the first electric slides 21 .

[0037] A plasma cutting head 23 is provided on the second electric slide 22 .

[0038] The plasma cutting head 23 is linearly driven by the first electric slide 21, and the plasma cutting head 23 is linearly driven by the second electric slide 22. The cutting position of the plasma cutting head 23 is flexibly adjusted. The plasma cutting head 23 moves along a specified path to cut a finished material of specified specifications on the material plate 4.

[0039] The unloading mechanism 35 is slidably connected to the driving frame 34 , and the unloading mechanism 35 is located below the material plate 4 . The cut finished materials will fall onto the elastic layer 352 below, and multiple groups of finished materials will be collected centrally through the elastic layer 352 .

[0040] Working principle: When in use, according to the size of the material sheet 4, the distance between the first positioning platform 32 and the second positioning platform 33 is adjusted accordingly by adjusting the base 31, so that the position of the second positioning platform 33 of the first positioning platform 32 is adapted to the material sheet 4, and the two sides of the material sheet 4 are respectively placed on the first positioning platform 32 and the second positioning platform 33. There is no obstruction below the area to be cut of the material sheet 4, and the negative pressure pump assembly works, and the negative pressure hose 36 generates a negative pressure suction force, so that the multiple groups of negative pressure adsorption holes 331 at the upper ends of the first positioning platform 32 and the second positioning platform 33 generate a negative pressure adsorption force, which is adsorbed and fixed by the negative pressure adsorption force. The material plate 4 linearly drives the plasma cutting head 23 through an electric slide, and the cutting position of the plasma cutting head 23 is flexibly adjusted. The plasma cutting head 23 moves along a specified path to cut out finished materials of specified specifications on the material plate 4. The cut finished materials fall onto the elastic layer 352, and multiple groups of finished materials are collected centrally through the elastic layer 352. The remaining materials remain on the positioning table, realizing automatic separation between the remaining materials and the finished materials. No subsequent sorting is required. Applying a certain external force to the handle 353 can pull the unloading mechanism 35, and after the cutting is completed, the unloading of the finished materials is convenient.
