[0021] Example

[0022] The following is further described in conjunction with specific embodiments. Figure 1-Figure 4 As shown, this embodiment is a pre-coated film slitting device, including a variable pitch component 1, which includes a mounting plate 11, a guide slide 12 and a slider 13. Both sides of the mounting plate 11 are provided with vertical guide rails that slide with the guide slide 12, and the lower side of the mounting plate 11 is provided with a transverse guide rail 15 that slides with the slider 13. The guide slide 12 is provided with at least one inclined guide slot 121, and the upper end of the slider 13 is provided with a slide column 131 for engaging with the inclined guide slot 121; a lifting cylinder 16 is fixed on the mounting plate 11, and the lifting cylinder 16 is connected to the guide slide 12; a cutting component 2, which includes a cutting disc 21 and a rotating shaft 22, and the cutting disc 21 is installed on the rotating shaft 22 and is slidably connected thereto; the lower end of the slider 13 is provided with a support plate 132, the lower end of the support plate 132 is in rolling contact with the middle part of the cutting disc 21; specifically, when in use, the pre-coated film passes under the cutting disc 21. Before the position of the cutting disc 21 is adjusted, a pressing roller is used to press down so that the surface of the pre-coated film does not contact the cutting disc 21. The lifting cylinder 16 moves downward to drive the guide slide plate 12 to move, and then the inclined guide groove 121 drives the slide column 131 and the slide block 13 to move the adjustment position laterally. Since the support plate 132 is in rolling contact with the cutting disc 21, the support plate 132 drives the cutting disc 21 to slide and move along the rotating shaft 22, thereby completing the adjustment of the spacing between two adjacent cutting discs 21 to obtain pre-coated film products of different widths. The operation is simple and convenient. In other words, the extension and retraction of the lifting cylinder 16 controls the approach and distance of adjacent cutting discs 21.

[0023] Reference Figure 2 and Figure 4 As shown, a ball 133 is embedded in the lower end of the support plate 132 in this embodiment, and a guide arc groove 211 adapted to the ball 133 is provided in the middle of the cutting disc 21; the surface of the rotating shaft 22 is provided with a linear groove 221 arranged along the axial direction, and the inner hole wall of the cutting disc 21 is provided with a clamping protrusion 212 corresponding to the linear groove 221; the clamping protrusion 212 is a semicircular structure; specifically, through the cooperation of the clamping protrusion 212 and the linear groove 221, the rotating shaft 22 can not only drive the cutting disc 21 to rotate normally, but also adjust the position of the cutting disc 21 along the axial direction of the rotating shaft 22, and the semicircular structure of the clamping protrusion 212 makes the operation smoother during the position movement; and the cooperation of the ball 133 and the guide arc groove 211 makes it possible that during the normal rotation of the cutting disc 21, the ball 133 can follow the rotation of the cutting disc 21 without interference, and during the movement of the slider 13, the support plate 132 and the ball 133 can also synchronously drive the cutting disc 21 to adjust the position along the rotating shaft 22.

[0024] like Figure 1 As shown, this embodiment also includes a driving motor 24, a first pulley 23 is installed at one end of the rotating shaft 22, a second pulley 25 is connected to one end of the driving motor 24, and a transmission is sleeved between the first pulley 23 and the second pulley 25; specifically, the power of the rotating shaft 22 is driven by the driving motor 24 through the second pulley 25, and is transmitted to the first pulley 23 and the rotating shaft 22 by the transmission belt 26 for driving.

[0025] like Figure 4 As shown, in order to ensure the continuous feeding and discharging of the pre-coated film during the slitting process, conveying guide rollers 3 are provided at the front and rear ends of the cutting component 2. The conveying guide rollers 3 at the rear end are mainly used to pull away the narrow width pre-coated film after slitting, and the axis of the conveying guide rollers 3 is parallel to the axis of the cutting disc 21.

[0026] like Figure 1 As shown, in order to ensure the equidistant and synchronous displacement of the two cutting discs 21 , two inclined guide slots 121 are symmetrically distributed on both sides of the mounting plate 11 .

[0027] It is worth noting that the inclined guide slot 121 is inclined at an angle of 45°, so that the slide block 13 has a longer lateral stroke under the premise that the cooperation between the slide post 131 and the inclined guide slot 121 has a smaller resistance.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
