[0038] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0039] Example 1: A galvanized coil cutting device, see Figures 1 to 5 , including a machine body 1, a cutting table 2 is arranged on the top side of the machine body 1, a laser cutting machine body 3 is arranged at the end of the top side of the machine body 1, and also includes an extrusion structure 4;

[0040] Two extrusion structures 4 are sequentially arranged on the cutting table 2; wherein the two extrusion structures 4 are symmetrically distributed with the cutting position of the laser cutting machine body 3 as the central axis;

[0041] The extrusion structure 4 includes a fixed plate 401 and a round roller 402;

[0042] Two fixed plates 401 are symmetrically fixed at both ends of the top side of the cutting table 2 ; a round roller 402 is rotatably arranged between the two fixed plates 401 .

[0043] The utility model provides a fixed plate 401 and a round roller 402, so that the unrolled galvanized sheet passes between the two round rollers 402. The round rollers 402 squeeze the galvanized sheet passing through, so that the galvanized sheet at the cutting position of the laser cutting machine body 3 remains relatively flat, which is convenient for cutting. This solves the problem that the unrolled galvanized sheet at the cutting position of the corresponding cutting machine is prone to curling and affecting cutting.

[0044] Specifically, the extrusion structure 4 further includes an annular spring piece 403;

[0045] A plurality of annular spring pieces 403 are equidistantly sleeved on the round roller 402 ; wherein the cross section of the annular spring piece 403 is designed with an arc structure, and the arched end of the annular spring piece 403 faces outward.

[0046] The utility model provides the annular spring piece 403 so that when the unwound galvanized sheet passes between the two round rollers 402, the annular spring piece 403 contacts the galvanized sheet and is squeezed to generate a rebound force to resist the galvanized sheet, thereby further keeping the galvanized sheet flat.

[0047] Furthermore, a groove 201 is provided on the top side of the cutting table 2 between the two round rollers 402, and a lifting structure 5 is arranged at the groove 201;

[0048] The lifting structure 5 includes a lifting bar 501, a connecting plate 504, a U-shaped frame 503 and a hydraulic cylinder body 505;

[0049] The lifting bar 501 is movably arranged in the groove 201; wherein, a cutting groove 502 is opened in the middle of the top side of the lifting bar 501, and the cutting groove 502 corresponds to the laser cutter of the laser cutting machine body 3; two connecting plates 504 are respectively fixed on the bottom of the two ends of the lifting bar 501; two U-shaped frames 503 are respectively fixed on the top side of the cutting table 2 at both ends of the groove 201; two hydraulic cylinder bodies 505 are respectively fixed on the top side of the horizontal sections of the two U-shaped frames 503; the hydraulic cylinder body 505 is selected and used by technical personnel in this profession according to actual conditions; wherein, the piston rod of the hydraulic cylinder body 505 is passed through the horizontal section of the U-shaped frame 503, and the bottom end of the piston rod of the hydraulic cylinder body 505 is fixedly connected to the connecting plate 504.

[0050] The utility model is provided with a lifting bar 501, a connecting plate 504, a U-shaped frame 503 and a hydraulic cylinder body 505. After the unwound galvanized sheet passes between the two round rollers 402, the hydraulic cylinder body 505 drives the lifting bar 501 to move upward, and cooperates with the annular spring piece 403 to abut the galvanized sheet to form a force with an upward middle and a downward end, so that the galvanized sheet is in a straight state for easy cutting.

[0051] Furthermore, the top of the lifting bar 501 is configured to be arc-shaped, and the top of the arc-shaped lifting bar 501 contacts the galvanized sheet and does not scratch the galvanized sheet when lifting it.

[0052] It is worth noting that the height of the lifting bar 501 is less than the depth of the groove 201, and the lifting bar 501 can be completely retracted into the groove 201 without affecting the passage of the galvanized sheet.

[0053] Working principle: When using the device of the present invention, the unrolled galvanized sheet passes between the two round rollers 402, and the annular spring piece 403 contacts the galvanized sheet and is squeezed to generate a rebound force against the galvanized sheet, so that the galvanized sheet remains flat, and the piston rod of the hydraulic cylinder body 505 moves upward to drive the connecting plate 504 to move upward, and the lifting bar 501 moves upward, and cooperates with the annular spring piece 403 to abut the galvanized sheet to form a force with an upward middle and downward ends, so that the galvanized sheet is in a straight state; the driving mechanism of the laser cutting machine body 3 drives the laser cutter of the laser cutting machine body 3 to move horizontally to cut the galvanized sheet. After the cutting is completed, the hydraulic cylinder body 505 drives the connecting plate 504 to move downward, and the lifting bar 501 is retracted into the groove 201.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
