Description

Technical Field

[0001] This utility model relates to the field of metal strip slitting technology, and in particular to a metal strip slitting machine. Background Technology

[0002] A slitting machine is a processing device that longitudinally cuts metal strip coils. By conveying the metal strip to the shearing rollers in a moving manner, the metal strip can be cut into strips.

[0003] Existing patent CN220028829U discloses a slitting machine, including a mounting frame with a slitting assembly on the frame. The slitting assembly includes a motor, a first rotating shaft, a slitting shaft, a second rotating shaft, and two first flanges. However, in the operation of the aforementioned slitting machine, the steel strip is not guided during the metal strip conveying process. Because the metal strip is conveyed and cut in a moving manner, the metal strip is prone to positional displacement during the moving cutting process, resulting in the cut metal strips often failing to meet the standard size.

By driving the mounting bracket 21 to move horizontally through the servo electric cylinder 24, the distance between the two guide limit rollers 23 can be adjusted according to the width of the metal strip.

[0027] Among them, combined Figure 1 and Figure 4 As shown, the slitting assembly 3 includes a slitting frame 37 and a lifting plate 32 located above the base 1. The slitting frame 37 is equipped with a lifting mechanism for moving the lifting plate 32 up and down.

[0030] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0031] For example, in other embodiments, unlike the embodiments described above, a limiting plate 25 is horizontally provided on the vertical part, and a pressure rod 26 is vertically slidably passed through the limiting plate 25. A positioning frame 29 is provided at the lower end of the pressure rod 26, and a pressure roller 28 is rotatably provided on the positioning frame 29.

The pressure rod 26 can be locked by the first locking bolt 27, so that the pressure roller 28 abuts against the metal strip, forming an upper and lower limit on the metal strip, further enhancing the limiting effect.

[0032] The working principle of this application is as follows: This application is set on the metal strip production line. The metal strip enters the slitting assembly 3 through the guide limiting mechanism 2. According to the width of the metal strip, the distance between the two mounting brackets 21 is adjusted by two servo electric cylinders 24 so that the guide limiting roller 23 abuts against both sides of the metal strip and the support roller 22 supports the metal strip to achieve initial guidance and limiting. The pressure rod 26 is adjusted so that the pressure roller 28 abuts against the metal strip to complete the precise limiting.

[0033] The height of the lifting plate 32 is adjusted by the electric telescopic rod 31 so that the longitudinal slitting blade 36 of the upper slitting component is in a suitable slitting position, that is, the longitudinal slitting blade 36 of the upper slitting component and the longitudinal slitting blade 36 of the lower slitting component are in contact with each other. The two drive motors 34 drive the two longitudinal slitting rollers 35 to rotate relative to each other, and the metal strip is cut into strips under the action of the two longitudinal slitting blades 36.

[0034] After being slit, the strip-shaped metal strips enter the separating and guiding assembly 4. The gap between adjacent separating rings 43 separates and guides the strip-shaped metal strips, facilitating subsequent collection and processing. The position of the separating rings 43 on the separating and guiding rollers 42 can be adjusted and locked according to the width of the strip-shaped metal strips.
