[0030] In this embodiment, the overall shape of the fixing frame 20 is U-shaped, and the fixing frame 20 is fixedly connected to the base 1 by bolts. The setting of the U-shaped fixing frame 20 supports the movable seat 24, etc., and the bolt fixing method ensures the installation reliability of the fixing frame 20.

[0031] In this embodiment, two positioning pins 28 are fixed between the fixing frame 20 and the base 1 at both the front and rear sides, and a positioning groove 231 is provided on the rack 23 to be slidably connected to the positioning pin 28, and the positioning pin 28 is slidably connected to the positioning groove 231. The arrangement of the positioning pin 28 and the positioning groove 231 has a limiting effect on the rack 23, thereby ensuring the stability and smoothness of the rack 23.

[0032] In this embodiment, two connecting rods 21 are fixed in the opening of the fixing frame 20, and the connecting rods 21 pass through the movable seat 24 and are slidably connected to the movable seat 24. The setting of the connecting rods 21 guides the horizontal movement of the movable seat 24, ensuring the stability and smoothness of the movable seat 24.

[0033] In this embodiment, two adjacent transmission components 16 are staggered, and the transmission component 16 includes two symmetrical pulleys 161, and a belt 162 is sleeved between the two pulleys 161; and the pulley 161 is coaxially keyed to the end of the corresponding conveying roller 15.

[0037] It is worth noting that the first motor 13, the second motor 14 and the third motor 27 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0038] When in use, the user first turns on the power of the first motor 13 and the second motor 14, and the first motor 13 and the second motor 14 start to work. The output shaft of the first motor 13 drives the slitting roller 12 to rotate, and the output shaft of the second motor 14 drives the conveying roller 15 to rotate. The pulley 161 rotates synchronously with the conveying roller 15. As the conveying roller 15 rotates, the pulley 161 rotates. Driven by the belt 162, multiple conveying rollers 15 rotate. At this time, the user places the galvanized sheet at the top rear end of the base 1, and the rotating conveying roller 15 drives the galvanized sheet to move forward. At the same time, the user turns on the power of the first motor 13 and the second motor 14 starts to work. The output shaft of the first motor 13 drives the slitting roller 12 to rotate, and the output shaft of the second motor 14 drives the conveying roller 15 to rotate. The pulley 161 rotates synchronously with the conveying roller 15. As the conveying roller 15 rotates, the pulley 161 rotates. Under the drive of the belt 162, multiple conveying rollers 15 rotate. At this time, the user places the galvanized sheet at the top rear end of the base 1, and the rotating conveying roller 15 drives the galvanized sheet to move forward. At the same time, the user turns on the power of the first motor 13 and the second motor 14 starts to work. The power supply of the third motor 27 is turned on, and the third motor 27 starts to work. The output shaft of the third motor 27 rotates to drive the gear 22 to rotate, and the gear 22 drives the racks 23 on both sides to move, and the racks 23 drive the movable seats 24 on both sides to move synchronously. The movable seat 24 simultaneously drives the connecting rod 21 to slide along the guide groove 10, and the connecting rod 21 synchronously drives the correcting wheel 26 to move. When the correcting wheel 26 is pressed against the two side walls of the galvanized sheet, the user stops the power supply of the third motor 27. At this time, the galvanized sheet moves forward under the restriction of the correcting wheels 26 on both sides, and the galvanized sheet is corrected. When the galvanized sheet moves to the slitting roller 12, the galvanized sheet is slit.
