A dust collection hood 3-10 is provided on the side surface of the movable frame 3-2. A connecting pipe 3-11 is connected between the movable frames 3-2, and the connecting pipe 3-11 is connected to the air cavity 3-9.

[0035] In this embodiment, in order to achieve the effect of adjustable grinding spacing and dust collection and cooling, a grinding and dust collection component 3 is designed. A transverse lead screw 3-1 with a double-headed threaded structure is arranged on the top of the outer frame 2. Both ends of the transverse lead screw 3-1 are connected to a moving frame 3-2 through threaded cooperation. The two moving frames 3-2 can move synchronously toward the middle. A driving motor 3-3 and a self-rotating transmission shaft 3-4 are installed at the bottom of the moving frame 3-2. A transmission wheel 3-7 is arranged at the output end of the driving motor 3-3 and the outside of the transmission shaft 3-4. The driving motor 3-3 can be used as power to make the transmission shaft 3-4 rotate at a high speed. -4 is provided with a slot 3-5 at the upper end and a trimmer 3-6 is inserted and connected in the slot 3-5. The trimmer 3-6 and the transmission shaft 3-4 are fixedly connected by bolts to facilitate disassembly and replacement. The trimmer 3-6 controls the distance from the strip steel through the transverse lead screw 3-1. An air cavity 3-9 is provided inside the movable frame 3-2 and is connected with a dust hood 3-10. A dust collecting device 3-8 is installed on the side surface of the movable frame 3-2. The dust collecting device 3-8 can be used to make the dust hood 3-10 generate suction to collect the debris and powder generated by the trimmer 3-6 during trimming, and at the same time, the surrounding gas can flow to produce a heat dissipation effect.

[0036] Furthermore, the correction conveying assembly 4 includes a conveyor belt 4-1, which is arranged on the surface of the bottom plate 1, a pair of side frames 4-2 are fixedly connected to the top of the outer frame 2, a pair of clamping rollers 4-3 are connected between the side frames 4-2, and a pair of telescopic cylinders 4-4 are arranged on the surfaces of both sides of the conveyor belt 4-1, a connecting frame 4-5 is arranged at the output end of the telescopic cylinder 4-4, and a correction frame 4-6 is fixedly connected to one end of the connecting frame 4-5.

[0037] In this embodiment, in order to achieve the effect of maintaining a straight and stable conveying of the steel strip, a correction conveying assembly 4 is designed, a conveyor belt 4-1 is installed on the base plate 1, and telescopic cylinders 4-4 and correction frames 4-6 fixedly connected by connecting frames 4-5 are arranged on both sides of the conveyor belt 4-1. The correction frames 4-6 are adjusted according to the different widths of the steel strips and are sleeved on both ends, so that the steel strip can maintain a straight state when being conveyed by the conveyor belt 4-1, and a side frame 4-2 is arranged on the top of the outer frame 2, and a clamping roller 4-3 is connected between the side frames 4-2. The clamping roller 4-3 presses on the surface of the steel strip being conveyed to improve the conveying stability.

[0038] Furthermore, the cross section of the correction frame 4-6 is a U-shaped structure.

[0039] In this embodiment, the U-shaped structure enables the correction frame 4-6 to be mounted on the side end of the strip to play a correction role.

[0040] Furthermore, the transmission wheels 3-7 are connected by belt transmission.

[0041] In this embodiment, the transmission between the driving motor 3 - 3 and the transmission shaft 3 - 4 is made more stable through the transmission of the belt.

[0042] Furthermore, the cross-sections of the connecting parts of the slot 3-5 and the trimmer 3-6 are both polygonal structures.

[0043] In this embodiment, the polygonal structure allows the slot 3-5 and the trimmer 3-6 to maintain a fixed plug-in connection and can rotate stably and at high speed along with the transmission shaft 3-4.

[0044] When the strip needs to be trimmed, put the strip between the conveyor belt 4-1 and the pressure roller 4-3, start the telescopic cylinder 4-4 to adjust the straightening frame 4-6 according to the width of the strip, ensure that the straightening frame 4-6 is mounted on both ends of the strip, then start the transverse screw 3-1 to make the movable frames 3-2 at both ends move synchronously, and make the trimmer 3-6 contact the two ends of the strip, start the drive motor 3-3, so that the transmission wheel 3-7 drives the trimmer 3-6 to rotate at high speed, and start the conveyor belt 4-1 to start conveying the steel on the conveyor belt 4-1. After trimming starts, start the dust collection device 3-8 to make the dust collection hood 3-10 generate suction, inhale dust and dissipate heat at the same time. When the trimmer 3-6 needs to be replaced due to high wear and tear, remove the bolts at the bottom, pull out the trimmer 3-6 from the slot 3-5 of the transmission shaft 3-4 and replace it with a new one.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
