[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1-7, which is the first embodiment of the utility model, provides a plasma cutting machine, which includes a workbench 1, a back plate 2 installed on the top of the workbench 1, a cutting plate 3, and a cutting knife 4. A splash guard 5 is installed on the top of the workbench 1, and a collecting member 6 is installed inside the workbench 1;

[0030] The collecting member 6 includes a storage groove 61 movably sleeved inside the workbench 1, a high temperature resistant cloth 62 is installed inside the storage groove 61, through holes 64 are provided at both ends of the high temperature resistant cloth 62, a threaded hole 65 is provided on the surface of the storage groove 61, two groups of threaded holes 65 are provided, and both are located at the bottom of the through hole 64, a bolt 63 is movably connected inside the through hole 64, the bolt 63 passes through the through hole 64 and extends to the inside of the threaded hole 65 and is threadedly connected to the storage groove 61, a handle 66 is fixedly connected to one side of the storage groove 61, and the splash guard 5 includes a transparent cover 51 installed at the bottom of the cutting board 3, a baffle 52 is movably connected to the inner side of the transparent cover 51, sliding grooves 531 are provided on both sides of the baffle 52, a connecting block 53 is fixedly connected to the inner side of the transparent cover 51, the baffle 52 is located at the top of the connecting block 53, and the baffle 52 is fixedly connected to the inner side of the transparent cover 51. Both sides are fixedly connected with limit blocks 56, which are located inside the limit groove 54 and are movably connected thereto. Both sides of the baffle 52 are fixedly connected with springs 55, and the other end of the spring 55 extends to the inside of the connecting block 53 and is fixedly connected thereto. A telescopic rod 551 is provided inside the spring 55, and the two ends of the telescopic rod 551 are respectively fixedly connected to the connecting block 53 and the baffle 52. A connecting column 57 is fixedly connected to the surface of the baffle 52, and one end of the connecting column 57 is fixedly connected to a chain 58. A positioning hole 59 is provided on the top of the transparent cover 51, and one end of the chain 58 is located inside the positioning hole 59 and is movably connected thereto. A groove 521 is provided inside the workbench 1, and the bottom of the baffle 52 passes through the transparent cover 51 and extends to the inside of the groove 521. A clamp 7 is installed inside the transparent cover 51.

[0031] After the plate is positioned, the chain 58 can be pulled to drive the baffle 52 to rise along the two sides of the connecting block 53, and the spring 55 can be stretched and one end of the telescopic rod 551 can be extended. At the same time, the baffle 52 will rise along the inner limiting groove 54 of the transparent cover 51 through the limiting blocks 56 on both sides during the rising process. When the top of the baffle 52 is in contact with the inner side of the transparent cover 51, the chain 58 is unfolded and one end of the chain is inserted into the inside of the positioning hole 59, so that the positioning of the baffle 52 can be completed.

[0032] And because the cutting plate 3 is adapted to the top of the transparent cover 51, when the cutting plate 3 descends to the top of the transparent cover 51, the gap can be blocked, thereby preventing slag from splashing onto the operator, further improving the safety during cutting. The lifting and lowering of the cutting plate 3 is achieved by the transmission shaft and sliding rod inside the back plate 2.

[0033] Since the transparent cover 51 is connected to the storage groove 61, the slag generated during cutting will fall into the inside of the storage groove 61 due to gravity, and since a high-temperature resistant cloth 62 is installed inside the storage groove 61, the slag will fall onto the surface of the high-temperature resistant cloth 62. After the cutting operation is completed, the handle 66 can be pulled to separate the storage groove 61 from the workbench 1, and then the bolt 63 can be twisted in the opposite direction to separate it from the threaded hole 65, and the high-temperature resistant cloth 62 can be taken out and replaced. In this way, the high-temperature slag can be prevented from falling into the storage groove 61 and then adhering to the inside after cooling, thereby solving the problem of inconvenience in cleaning, and further solving the problem that when the high-temperature slag comes into contact with the liquid, it will cause a chemical reaction or combustion and generate heat and gas, which will affect the operator's line of sight and thus be detrimental to the normal progress of the cutting operation.

One end of the hydraulic cylinder 71 extends into the interior of the transparent cover 51 and is fixedly connected to the L-shaped plate 72 .

[0037] During use, the plate to be cut is placed on the surface of the L-shaped plate 72, and then the hydraulic cylinder 71 is started to push the L-shaped plate 72, so that the two groups of L-shaped plates 72 are close to each other until the plate is completely clamped, thereby achieving the purpose of positioning the plate, and further solving the problem that the plate will move during cutting if it is not positioned, resulting in inaccurate cutting.

[0038] The remaining structures are the same as those of Example 1.
