Description

An eccentric down-cutting mechanism of a slitting machine

technical field

The utility model relates to the technical field of strip film cutting, in particular to an eccentric down-cutting mechanism of a slitting machine.

Background technique

The slitting machine is a cutting device that slits the strip into several strips of required specifications. Its main function is to slit the entire roll of film to obtain several films with smaller widths. The existing slitter The machine mainly uses the upper cutter and the lower cutter for cutting, especially for the lower cutter, because it needs to cooperate with the upper cutter, so the adjustment of the lower cutter is quite frequent, and the traditional adjustment method is mainly based on bolts. The bolts of this fixing method must be limited in the screw holes of the lower cutter, and must not be exposed, otherwise it will affect the normal cutting of materials. Obviously, there are relatively large defects in the existing lower cutter mechanism. In view of Therefore, the present inventors made improvements.

Utility model content

The purpose of the utility model is to provide an eccentric lower cutting mechanism of a slitting machine for the deficiencies of the prior art. The lower cutting mechanism can be directly fixed by the lower cutter and the roller without bolts.

In order to achieve the above purpose, an eccentric undercut mechanism of a slitting machine of the present invention includes a rotatable lower roller, the outer wall of the lower roller is provided with at least one adjustment plane, and also includes a plurality of The lower cutter is provided with an inner hole matched with the lower roller, and at least one arc-shaped rib is arranged in the inner hole, and the arc-shaped rib matches the gap between the adjustment planes.

Further, the lower cutter includes a knife ring body, and the knife ring body is provided with at least one knife-limiting groove, and the section of the knife-limiting groove is trapezoidal.

Preferably, two knife-limiting grooves are arranged side by side, and auxiliary screw holes are provided between the two knife-limiting grooves, and the auxiliary screw holes are screwed with auxiliary bolts for abutting against the outer surface of the lower roller.

More preferably, the inner hole of the knife ring body is provided with an extension part, and the extension part is provided with an adjustment ring for clamping the rotating knife ring body.

Further, the lower cutter includes a knife ring body, and the knife ring body is provided with at least one knife-limiting groove, and the section of the knife-limiting groove is V-shaped.

Further, both ends of the arc-shaped rib extend toward the inner hole and are tangent, and the maximum depth of the arc-shaped rib extending toward the inner hole is 2mm.

Beneficial effects of the utility model: the eccentric cutting mechanism of the slitting machine of the utility model includes a rotatable lower roller, the outer wall of the lower roller is provided with at least one adjustment plane, and also includes a plurality of lower rollers The lower cutter is connected with the cylinder, the lower cutter is provided with an inner hole that matches the lower roller, and at least one arc-shaped rib is arranged in the inner hole, and the arc-shaped rib matches the clearance of the adjustment plane; the eccentric lower cutter When the mechanism is adjusted, multiple lower cutters are inserted into the lower roller. Since there is a gap between the arc-shaped ribs and the adjustment plane, the lower cutters can be smoothly inserted into the lower roller, and then the lower cutters are rotated sequentially. The lower cutter has an eccentric structure, so that the arc-shaped ribs are misaligned with the adjustment plane, and the arc-shaped ribs are used to closely match the side wall of the lower roller. When it needs to be removed, turn the lower cutter in the opposite direction to make the arc The ribs and the adjustment plane are re-coordinated. The lower cutting mechanism directly uses the lower cutter and the roller to fix without bolts. The fixing effect is good and the debugging is more convenient.

detailed description

Below in conjunction with accompanying drawing 1 to accompanying drawing 4 the utility model is described in detail.

An eccentric lower cutting mechanism of a slitting machine of the present utility model includes a rotatable lower roller 61, the outer wall of the lower roller 61 is provided with at least one adjustment plane 611, and also includes a plurality of rollers connected to the lower roller 61. The lower cutter 62, the lower cutter 62 is provided with an inner hole 621 that cooperates with the lower roller 61, and at least one arc-shaped rib 622 is arranged in the inner hole 621, and the gap between the arc-shaped rib 622 and the adjustment plane 611 Matching; when the eccentric lower cutting mechanism is adjusted, a plurality of lower cutting knives 62 are inserted into the lower roller 61. Since there is a gap between the arc-shaped ribs 622 and the adjustment plane 611, the lower cutting knives 62 can be smoothly inserted into the lower roller In the barrel 61, the lower cutter 62 is then rotated in turn. Since the lower cutter 62 has an eccentric structure, the arc-shaped rib 622 is misaligned with the adjustment plane 611, and the arc-shaped rib 622 is closely matched with the side wall of the lower roller 61. When it needs to be removed, turn the lower cutter 62 in the opposite direction to make the arc-shaped rib 622 and the adjustment plane 611 re-fit. This lower cutting mechanism directly uses the lower cutter 62 to fix with the roller, without bolts, and the fixing effect is good. , debugging is more convenient.

In this technical solution, the lower cutter 62 includes a knife ring body 623, and the knife ring body 623 is provided with at least one knife limiting groove 624, and the section of the knife limiting groove 624 is trapezoidal. The knife limiting groove 624 can form a restriction on the upper knife, so that when the upper knife and the lower cutting knife 62 of the slitting cooperate, a more accurate knife path can be cut out, and the trapezoidal shape can also make the upper knife in the center of the knife limiting groove 624 position for cropping.

Of course, as a further improvement, two knife-limiting grooves 624 are arranged side by side, and auxiliary screw holes 625 are provided between the two knife-limiting grooves 624. Auxiliary bolts 63 on the outer surface of the roller 61 . The auxiliary bolt 63 can further strengthen the connection stability between the lower cutter 62 and the lower roller 61. When it needs to be emphasized, since this solution is set as two knife-limiting grooves 624, and the auxiliary screw hole 625 is arranged on the two knife-limiting grooves Therefore, when the auxiliary bolt 63 is cutting, even if it is exposed, it will not affect the normal cutting.

In this technical solution, the inner hole 621 of the knife ring body 623 is provided with an extension part, and the extension part is provided with an adjustment ring 626 for clamping the rotating knife ring body 623 . Since the knife ring body 623 is circular, the adjustment ring 626 can be used for better clamping and fixing, so that the adjustment of the knife ring body 623 is more convenient.

Referring to Fig. 4 for details, as another embodiment, the lower cutter 62 includes a knife ring body 623, and the knife ring body 623 is provided with at least one knife limiting groove 624, and the section of the knife limiting groove 624 is V-shaped. This V-shape is suitable for a thinner upper cutter, and when the upper cutter reaches the upper limit slit 624, the V-shaped limited slit 624 can provide a more precise cutting position.

In this technical solution, the two ends of the arc-shaped ribs 622 extend toward the inner hole 621 and are tangent to each other. This natural extension forms a tangential smooth transition, which is conducive to smoother cutting of the knife 62 under the rotary support. According to the actual For trial use, the maximum depth of the arc-shaped rib 622 protruding toward the inner hole 621 can reach 2mm.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
