Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, and more specifically, to a slitting mechanism of a slitting machine. Background Art

[0002] The slitting machine is a device used to cut wide paper, mica tape or film into fixed lengths and rewind them to fixed lengths. At the same time, the slitting machine has the function of cutting wide paper, mica tape or film into multiple narrow materials. Therefore, it is often used in papermaking machinery, wire and cable mica tape and printing and packaging machinery.

[0003] The width specification of the film cut by the existing film slitting machine is fixed, so it cannot be cut into film products of different width specifications, and there is a problem of low adaptability to the width. The existing patent is a slitting mechanism of a slitting machine, and the patent authorization number is CN213165604U. The spacing between each cutter component can be adjusted, so that the slitting machine can cut wide materials into film products of various widths.

[0004] However, the fixing component on the knife holder in patent authorization number CN213165604U can be set as a second bolt, the second bolt passes through the second notch and is threadedly connected to the second threaded hole, and the tightness of the knife holder is fine-tuned by tightening the second bolt on the knife holder to achieve movement and fixation of the knife holder on the cutting roller. Since the bolts need to be tightened with the threaded holes in the process of adjusting the cutting knife spacing, not only the adjustment efficiency is low, but also the operation is very inconvenient. Therefore, we propose a slitting mechanism of the slitting machine to solve the above problems. Utility Model Content

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Example:

[0031] See also Figure 1-6 A slitting mechanism of a slitting machine comprises a slitting machine body 1 and a reel 2 rotatably connected to the slitting machine body 1, wherein a slitting mechanism is installed on one side of the reel 2;

[0032] The slitting mechanism includes a cutting roller 3 connected to the slitting machine body 1, a guide groove 17 symmetrically provided on the outer wall of the cutting roller 3 in the axial position, a slitting knife 4 installed on the outside of the cutting roller 3, a guide block 5 symmetrically fixedly connected to the inner side of the slitting knife 4 and slidingly connected to the guide groove 17, a through groove 6 provided on the surface of the slitting knife 4, a positioning column 7 installed on the inner side of the through groove 6, a positioning hole 16 provided on the outer wall of the cutting roller 3 and plugged into the bottom end of the positioning column 7, an assembly groove 8 provided on the top wall of the through groove 6, a spring 9 installed on the inner side of the assembly groove 8, a limit block 10 installed on the top end of the positioning column 7 and located on the inner side of the assembly groove 8, a stopper 11 installed on the inner side of the bottom of the assembly groove 8 and fitted with the limit block 10, a limit slide 12 symmetrically provided on the inner side wall of the through groove 6, and a slider 13 symmetrically fixedly connected to the outer wall of the positioning column 7 and with the end thereof having a clearance fit with the limit slide 12;

[0033] It should be noted that when the slitting mechanism of the slitting machine is adjusted, the spacing between the positioning holes 16 provided on the cutter roller 3 is the fixed adjustment spacing for the paper to be cut;

[0034] By dragging the positioning post 7 upward, the bottom end of the positioning post 7 is separated from the currently inserted positioning hole 16, and the positioning post 7 is prevented from rotating in the process of the slider 13 cooperating with the limiting slide groove 12. The limiting block 10 is used to compress and deform the spring 9 located inside the assembly groove 8, so that the slitting knife 4 slides in the axial direction of the slitting roller 3, and the guide block 5 is used to cooperate with the guide groove 17 to prevent the slitting knife 4 from rotating, so that the positioning post 7 corresponds to the positioning hole 16. After adjusting the spacing between the slitting knives 4 according to the width of the paper to be cut, the elastic force of the spring 9 is used to connect the positioning post 7 with the corresponding positioning hole 16, which not only improves the adjustment efficiency but also makes the operation very convenient.

[0035] like Figure 4 As shown, the outer wall of the positioning column 7 is fixedly connected with a protrusion 14, and both ends of the protrusion 14 extend to the end portion of the through groove 6. The end of the protrusion 14 is provided with an inclined surface, and the inclined surface is integrally formed with an anti-slip protrusion 15;

[0036] It should be noted that by utilizing the protrusion 14 to drag the positioning post 7 upward, the anti-slip protrusion 15 provided on the inclined surface of the end of the protrusion 14 can increase the friction with the hand.

[0037] like Figure 3、 Figure 4 As shown, a plurality of positioning holes 16 are equidistantly provided in the axial position of the cutter roller 3, and the inner diameter of the positioning hole 16 is adapted to the outer diameter of the bottom end of the positioning column 7;

[0038] It should be noted that the stability of the assembly between the slitting knife 4 and the slitting roller 3 is ensured.

[0039] like Figure 6 As shown, one end of the spring 9 abuts against the top wall of the assembly groove 8, and the other end of the spring 9 abuts against the limit block 10. The assembly groove 8 and the limit block 10 are both arranged in a cylindrical structure, and the outer diameter of the limit block 10 is adapted to the inner diameter of the assembly groove 8. The stopper 11 is arranged in an annular structure, and the inner diameter of the stopper 11 is smaller than the outer diameter of the limit block 10;

[0040] It should be noted that, under the elastic force of the spring 9 , the positioning column 7 is pushed to move downward, and the limiting block 10 abuts against the stopper 11 , thereby limiting the positioning column 7 .

[0041] During use: by dragging the positioning post 7 upward, the bottom end of the positioning post 7 is separated from the currently inserted positioning hole 16, and the positioning post 7 is prevented from rotating in the process of the slider 13 cooperating with the limiting slide groove 12, and the limiting block 10 is used to compress and deform the spring 9 located on the inner side of the assembly groove 8, so that the slitting knife 4 slides in the axial direction of the slitting roller 3, and the guide block 5 is used to cooperate with the guide groove 17 to prevent the slitting knife 4 from rotating, so that the positioning post 7 corresponds to the positioning hole 16. After adjusting the spacing between the slitting knives 4 according to the width of the paper to be cut, the elastic force of the spring 9 is used to connect the positioning post 7 with the corresponding positioning hole 16, and then the paper is cut.

[0042] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
