Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further explained with reference to the specific drawings.

Referring to fig. 1, 2 and 3, the knife roll for producing the film filler comprises a rotating roll and a knife 4. At least two groups of spiral clamping groove groups are arranged on the rotary roller, and the clamping grooves 5 in the same clamping groove group are arranged in a staggered mode at equal intervals. The opening of the clamping groove 5 faces outwards, a baffle 3 is arranged in the clamping groove 5, a rotating shaft 7 is fixed on the baffle 3, a rotating shaft hole 2 is formed in the center of the cutter 4, and the cutter 4 is inserted in the rotating shaft 7. The cutter 4 is in a square block shape, one edge 6 of the cutter faces upwards and extends out of the clamping groove, and the edge 6 serves as a cutting edge. The other edge of the cutter faces downwards and is clamped in the clamping groove. A gap exists between the outer side wall of the cutter and the inner side wall of the clamping groove, so that the cutter can swing around the rotating shaft. The edge of the cutter which is positioned outside the clamping groove and faces upwards is used as a cutting edge.

Detailed description of the preferred embodiment 1

The inside wall of draw-in groove comprises the right lateral wall that is located the right side and is located the left side wall on left side, and left side wall and right side wall mirror symmetry. The central line axis of the rotating shaft is positioned on the mirror symmetry plane of the left side wall and the right side wall. At the moment, the central line axis of the rotating shaft and the central line axis of the rotating roller form an included angle of 90 degrees. The outer contour of the longitudinal section of the cutter is square or diamond.

The lower clamping groove and the cutter are of bilaterally symmetrical structures, and production and installation are very convenient. And the cutter not only can be turned over up and down, but also can be turned over left and right for alternative use. Further preferably: the left side wall and the right side wall are both planes. The included angle between the left side wall and the right side wall is 95 degrees to 110 degrees. The outer contour of the longitudinal section of the tool is preferably square.

Specific example 2

The inner side wall of the clamping groove consists of a left side wall positioned on the left side and a right side wall positioned on the right side, and the boundary line of the left side wall and the right side wall forms the bottom of the clamping groove. The central line axis of the rotating shaft and the central line axis of the rotating roller form an included angle of 85-89 degrees. The bottom of the slot and the centerline axis of the spindle are preferably parallel. The structure ensures that the cutting edge of the cutter forms an included angle with the central axis of the rotating shaft. The cutting edge of current cutter is perpendicular and the central line axis of changeing the roller, and the utility model discloses a prescribe a limit to the direction of pivot, makes the cutting edge of cutter can have certain contained angle with the perpendicular of the central line axis of changeing the roller to can be easier impale the film and make the shredding direction of film abundanter, and make the film produce certain coiling at the shredding in-process.

In this embodiment, the card slots in adjacent card slot groups are preferably oriented differently. That is, the card slots in one card slot group are inclined towards the left relative to the central line axis of the rotating roller, and the card slots in the adjacent card slot group are inclined towards the right relative to the central line axis of the rotating shaft. Thereby utilize the cutter direction difference of the cutter in two sets of draw-in grooves, come further richen shredding direction, improve the coiling degree.

Specific example 3

The front end surface 1 of the cutter is in a curved surface shape which is concave inwards. Thereby four corners at the front end of the cutter are tilted outwards, and the cutter can conveniently puncture the film by utilizing the corners. The rear end surface of the cutter is in a curved surface shape protruding outwards. Thereby reducing the contact area with the baffle and further reducing the swing resistance of the cutter. Particularly preferably, the curved surface of the front end face of the cutter is matched with the curved surface of the rear end face of the cutter, so that stacking is facilitated while stacking is allowed on the same rotating shaft.

Under this embodiment, there may be at least two cutters inserted on the same shaft. Therefore, the possible angle difference of the cutting edges between the front cutter and the rear cutter is utilized, the shredding direction is further enriched, and the winding degree is improved.

Specific example 4

The front end face and the rear end face of the baffle are respectively and fixedly connected with a rotating shaft, and cutters are respectively inserted in the two rotating shafts. The orientation of the two cutters may be the same or comparable. The baffle between the two knives serves to create a gap between the two knives which further increases the degree of winding. In this embodiment, the baffle plate may be provided with a rotation shaft hole, the rotation shaft passes through the rotation shaft hole, and both ends of the rotation shaft are respectively exposed at both sides of the baffle plate and respectively inserted with a cutter.

The technical characteristics of the four specific embodiments can be combined with each other.

In the above four embodiments, the baffle is preferably located in the middle of the slot. Further preferably, the blocking plate fills and levels the clamping groove where the blocking plate is located.

In the above four embodiments, the distance from the rotating shaft to the central line axis of the rotating roller is preferably gradually increased from the direction away from the baffle plate to the direction close to the baffle plate, and the rotating shaft is obliquely inserted into the cutter downwards, so that the front part of the cutter is closer to the bottom of the clamping groove, the probability that the film enters the bottom of the clamping groove is reduced, and meanwhile, the cutting edge is inclined, so that the film can be easily shredded.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed.
