Description

Technical Field

[0001] The utility model relates to a material strip stripping device for a circular knife die cutting machine, belonging to the technical field of material strip strip stripping equipment for circular knife die cutting machines. Background Art

[0002] When cutting the material strip into strips, a circular knife die-cutting machine is used. The material strip is quickly cut and stripped by rotating the circular knife. For example, a material strip slitting device of a circular knife die-cutting machine mentioned in the authorization announcement number CN216917956U includes a base, and fixed plates are vertically fixedly connected to both sides of the upper end of the base, and a first slide groove is opened in the middle position of the fixed plate, and a first slider is slidably connected inside the first slide groove, and a first roller is rotatably connected between the first sliders, and both ends of the first roller are fixedly connected to a first roller, and a second roller is rotatably connected to a position below the first roller between the fixed plates, and both ends of the second roller are fixedly connected to a second roller.

[0003] In this device, the stripping operation is completed by matching the cutting knife with the cutting support roller. However, in actual application, the researchers found that when the material strip is stripped, different width sizes need to be separated. At this time, it is difficult to adjust the position of the cutting knife, which is very inconvenient and not conducive to promotion and use. Utility Model Content

The spacing between the cutting knives and the spacing between the force rings can be adjusted as needed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0023] When in use, the material belt is passed between the first rotating column 5 and the second rotating column 6, and then the electric push rod 4 is controlled to extend. At this time, the first rotating column 5 is pressed down and approaches the second rotating column 6 until the pressure roller disc 7 on the outside of the first rotating column 5 and the pressure roller disc 7 on the outside of the second rotating column 6 are in contact with the material belt. At this time, the cutting knife 8 cuts the material belt and penetrates it into the groove on the outside of the force ring 9. Further, the start-up of the first servo motor 15 and the second servo motor 16 is controlled to drive the rotation movement of the first rotating column 5 and the second rotating column 6. The rotation of the pressure roller disc 7 drives the material belt to move. The rotation of the cutting knife 8 and the force ring 9 cuts the material belt into strips.

[0024] It should be noted that the outer diameter of the pressure roller 7 is the same as the outer diameter of the force ring 9, and the outer diameter of the cutting knife 8 is slightly larger than the pressure roller 7. During the cutting process, the cutting knife 8 matches the groove on the outside of the force ring 9 to complete the cutting of the material strip. This is a common technical means and will not be elaborated here.

[0025] As a preferred technical solution for the strip slitting device of a circular knife die-cutting machine of the utility model, one end of the first rotating column 5 is fixedly connected to a first servo motor 15, and one end of the second rotating column 6 is fixedly connected to a second servo motor 16; one side surface of the first servo motor 15 is fixedly connected to the embedding block 3, and one side surface of the second servo motor 16 is fixedly connected to the support base 1.

[0027] As an optimal technical solution for the strip slitting device of a circular knife die-cutting machine of the utility model, the cutting knife 8 matches the structural dimensions of the force ring 9, and a groove matching the cutting knife 8 is provided on the outer surface of the force ring 9 to ensure that the cutting knife 8 can cut the strip.

[0028] As an optimal technical solution for the strip slitting device of a circular knife die-cutting machine of the utility model, the inner surface of the cutting knife 8 and the inner surface of the force ring 9 are fixedly connected with a slider 19, and the outer surface of the first rotating column 5 and the outer surface of the second rotating column 6 are provided with a slide groove matching the structural size of the slider 19; the slider 19 moves in the slide groove to prevent the cutting knife 8 and the force ring 9 from rotating when moving left and right.

[0029] Example 2

[0030] See also Figure 2 , Figure 3 and Figure 4The difference between this embodiment and embodiment 1 is that:

[0031] Limiting holes 17 are provided on the outer surfaces of the first rotating column 5 and the second rotating column 6, and the limiting holes 17 match the structural dimensions of the limiting column 13; a pulling column 18 is fixedly connected to one end of the limiting column 13, and the limiting column 13 extends through one end away from the pulling column 18 and is movably connected to the extending block 10; one end of the pulling column 18 is slidably connected to the limiting box 11, and the limiting spring 14 is fixedly connected to the limiting box 11 at one end away from the moving plate 12, and the movement of the combination of the limiting column 13 and the moving plate 12 can be pulled by the pulling column 18.

[0032] It should be noted that: through the personnel in this field, all the electrical components in this case, such as the electric push rod 4, the first servo motor 15 and the second servo motor 16, are connected to the corresponding power supply through wires, and a suitable controller, such as a PLC controller or a single-chip microcomputer, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the working order. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0033] The working principle and use process of the utility model are as follows: when in use, when the position of the cutting knife 8 and the force ring 9 needs to be changed, first, the pulling column 18 on one side of the force ring 9 or the cutting knife 8 is used to pull the movement of the limit column 13 and the movable plate 12 combination, and the limit spring 14 is deformed to generate elastic force. At this time, the limit column 13 leaves the corresponding limit hole 17. Further, at this time, the force ring 9 combination or the cutting knife 8 combination can be pushed, and then the pulling column 18 is released. At this time, the limit spring 14 returns to its original state, driving the movement of the movable plate 12 and the limit column 13, and the limit column 13 is inserted into the corresponding limit hole 17 to limit the position of the force ring 9 or the cutting knife 8. The spacing between the cutting knives 8 and the spacing between the force rings 9 can be adjusted as needed.
