[0032] 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.

[0033] See also Figure 1-3 , the utility model provides a technical solution:

[0034] A flame cutting device comprising:

[0035] The main structure includes a bottom plate 1 and a top plate 3, a support frame 2 is welded to the bottom plate 1, and the top plate 3 is welded to the upper end of the support frame 2;

[0036] Cutting mechanism; the cutting mechanism includes a turntable 4, a spray gun 6 and a gas cylinder 26. A circular notch 17 is provided on the top plate 3. The turntable 4 is rotatably installed in the notch 17. The turntable 4 is driven by a rotating motor 16. A slide 5 is provided on the turntable 4. The spray gun 6 is slidably installed inside the slide 5. The gas cylinder 26 is fixed to one side of the bottom of the turntable 4, and the output end of the gas cylinder 26 and the input end of the spray gun 6 are connected together by a hose; a motor is fixedly installed at the center position of the bottom plate 1, and one end of the output shaft of the motor is fixedly connected to a shaft through a coupling, and the upper end of the shaft is fixed to the bottom center of the turntable 4.

[0037] Adjustment Mechanism: The adjustment mechanism comprises a fixed sleeve 20 that fits over the spray gun 6 and two sets of synchronously installed cylinders 22. The two sets of cylinders 22 are mounted at the bottom of the turntable 4 and located on either side of the chute 5. Adjustment plates 21 are symmetrically arranged on either side of the fixed sleeve 20. The piston rod ends of the two sets of cylinders 22 are respectively connected to the side walls of the two sets of adjustment plates 21. The spray gun 6 is provided with two sets of limit blocks 19, one set located at the upper and lower sides of the chute 5.

[0038] By setting a main structure including a bottom plate 1 and a top plate 3, a cutting mechanism including a turntable 4, a spray gun 6 and a gas cylinder 26 is set on the top plate 3, the turntable 4 is driven by a rotating motor 16, and the spray gun 6 is slidably installed on the turntable 4, and the spray gun 6 can adjust the cutting radius by an adjusting mechanism, the adjusting mechanism includes a cylinder 22 and a fixing sleeve 20. In actual use, the plate is placed directly above the top plate 3 and fixed, and the cutting mechanism is started. The spray gun 6 is supplied with dye by the gas cylinder 26 for cutting. When the rotating motor 16 is working, it can cut a circle on the plate. When the cutting radius needs to be adjusted, the cylinder 22 is used to drive the spray gun 6 to move to the required position in the slide 5. Since the cutting radius can be freely changed, circles, ellipses and arcs can be cut, which greatly increases the applicability of the device.

[0039] In general, the device has a simple structure and is easy to use. It can cut a circle on the plate through the cutting mechanism, and the cutting radius can be adjusted according to actual needs through the design of the adjustment mechanism, thereby realizing special-shaped cutting such as circle, ellipse and arc, and has high practical value.

[0040] See also Figure 4-5 In order to facilitate the installation and replacement of the gas cylinder 26, the present application makes the following design:

[0041] It also includes a supporting mechanism for supporting and fixing the gas cylinder 26. The supporting mechanism includes two sets of supporting plates 23 symmetrically arranged on one side of the turntable 4. The bottom of the supporting plates 23 is provided with a supporting ring, which is clamped on the outer wall of the gas cylinder 26 to fix and support the gas cylinder 26. The supporting ring includes a first positioning ring 24 and a second positioning ring 25. The lower ends of the first positioning ring 24 and the second positioning ring 25 are hinged together, and the upper ends of the first positioning ring 24 and the second positioning ring 25 are locked by fixing screws. The upper ends of the first positioning ring 24 and the second positioning ring 25 are both integrally formed with a connecting block, and only the connecting block at the upper end of the first positioning ring 24 is welded to the bottom of the supporting plate 23. The connecting blocks at the upper ends of the first positioning ring 24 and the second positioning ring 25 are both provided with through holes 27 for the passage of fixing screws.

[0042] Two sets of supporting plates 23 are provided on one side of the bottom of the turntable 4, a first positioning ring 24 is welded to the bottom of the supporting plate 23, and a second positioning ring 25 is hingedly connected to the lower end of the first positioning ring 24. When installing the gas cylinder 26, the gas cylinder 26 is clamped in the two sets of supporting rings, and the fixing screws are passed through the through holes 27 of the connecting blocks at the upper ends of the first positioning ring 24 and the second positioning ring 25 and locked;

[0043] When the gas cylinder 26 needs to be replaced, the fixing screws are removed. Since the first positioning ring 24 and the second positioning ring 25 are hinged, and the connecting block at the upper end of the second positioning ring 25 does not contact the bearing plate 23, the second positioning ring 25 can be rotated to freely remove the gas cylinder 26. The structure is simple and easy to use, which facilitates the rapid installation, use, removal and replacement of the gas cylinder 26 when the equipment is running.

[0044] Moreover, since the gas cylinder 26 is placed at the bottom of the turntable 4 through the supporting plate 23, when the turntable 4 rotates, the gas cylinder 26 will rotate accordingly, so the hose between the gas cylinder 26 and the spray gun 6 will not be entangled.

[0045] See also Figure 1 and Figure 6 In order to facilitate the cutting of the plate, this application makes the following design:

[0046] The cutting machine also includes a fixing mechanism for fixing the plate to be cut. The fixing mechanism includes two sets of fixing plates 7 symmetrically arranged on either side of the top plate 3. One side of the fixing plates 7 is provided with a fixing slot 8 for inserting the edge of the plate to fix the plate 7. Two sets of protruding plates 12 are symmetrically arranged on both sides of the top plate 3. A screw driven by a fixed motor 13 is rotatably mounted between the two sets of protruding plates 12. A guide rod 14 is disposed between the other two sets of protruding plates 12. One end of each set of fixing plates 7 is provided with a guide sleeve 15, which is slidably sleeved on the outside of the guide rod 14. The screw rod includes a first screw rod 9 and a second screw rod 10. The threads on the first screw rod 9 and the second screw rod 10 face opposite directions. A slide 11 is mounted on each of the first screw rod 9 and the second screw rod 10. The other ends of the two sets of fixing plates 7 are fixedly connected to one side of the two sets of slides 11.

[0047] Through the design of the fixing mechanism, in actual use, the two ends of the plate are inserted into the fixing grooves 8 of the two sets of fixing plates 7, and the distance between the two sets of fixing plates 7 is adjusted by the screw rod to clamp and fix the plate. Since the threads on the first screw rod 9 and the second screw rod 10 are in opposite directions, when the fixing motor 13 is started, the two sets of fixing plates 7 can be moved closer or farther away, so that they can be adapted accordingly according to the size of the plate, greatly improving the applicability of the device.

[0048] In addition, the fixed plate 7 is at a certain distance from the surface of the top plate 3. The advantage of this design is that it can facilitate the adjustment of the spacing between the fixed plates 7 and also make it easy for the staff to observe the position of the spray gun 6, thereby adjusting the cutting radius as needed.

[0049] See also Figure 1-4 In order to improve the safety and stability of this device, this application makes the following designs:

[0050] It also includes an auxiliary support mechanism, which includes an annular groove 18 opened at the notch 17 and an integrally formed edge 28 set on the turntable 4. A plurality of groups of universal balls 29 are distributed around the bottom of the edge 28, and the spherical surface of the universal ball 29 abuts against the inner bottom of the annular groove 18.

[0051] By opening an annular groove 18 at the notch 17 and installing a universal ball 29 at the bottom of the edge 28 on the turntable 4, the design of the universal ball 29 can provide additional auxiliary support while ensuring the rotation ability of the turntable 4, thereby improving the safety and stability of the device.
