Abstract

The utility model relates to a sectional perforating cutting device for toilet paper product. A discontinuity type dead knife which is connected with a dead knife rest is arranged on a machine frame, and a linear type movable knife is arranged on a knife roller which is driven by an actuating unit to rotate. The movable knife and the knife edge of the dead knife can do friction and shearing movement, wherein, the dead knife rest is connected with an elastic bearing structure through a support structure, and the elastic bearing structure is arranged on the machine frame.

Description

The segmentation hole-cutting device of sanitary tissue products

The utility model relates to a kind of in the toilet paper processing sanitary tissue products carry out the device that the hole is cut in segmentation.

Toilet paper is a kind of expendable paper products of a large amount of uses.Tear fracture when using for ease of the toilet paper of strip or drum is cut apart, and needs usually during production and processing that nibbling shear goes out to reserve on rectangular paper web is the branch that is interrupted the dotted line shape and cuts off the hole with specific segmentation hole-cutting device.It cuts the hole generally is by being arranged at linear pattern cutting blade on the rotor that can drive be rotated by actuating unit in the hole-cutting device when rotating, be connected in frame on immovable support on the fixed blade of the set discontinuous fricting shearing motion when its two edge of a knife contacts, done realize.Because the said fixing blade in this class hole-cutting device is the form that is fastenedly connected on frame at present, fricting shearing motion when the edge of a knife moving, ledger-plate contacts is the contact of a kind of " confronting the tough with toughnees " impacting type, therefore the wearing and tearing of the edge of a knife are very fast and serious, and vibration and noise are also very serious.Edge of a knife wearing and tearing back since its gap increase, will occur to paper web to cut the hole imperfect, unclear, even do not cut the hole fully.And the adjustment in its edge of a knife gap is still had great difficulty at present, when the gap was bigger than normal, it was of poor quality to cut the hole; When the gap is less than normal, the running resistance of equipment be can increase again, equipment stall or damage blade also can be caused when serious.

The purpose of this utility model is to provide a kind of hole quality that both can guarantee to cut for addressing the above problem, and can prolong the segmentation hole-cutting device of the sanitary tissue products in blade service life again significantly.

Sanitary tissue products segmentation hole-cutting device of the present utility model, its frame are provided with the discontinuous fixed blade that is connected on the immovable support and are arranged at and can be driven on the rotor that rotates and can be made the linear pattern cutting blade of fricting shearing motion with the fixed blade edge of a knife by actuating unit.Immovable support wherein is connected with elasticity support structure on being arranged at frame through supporting structure.Elasticity support structure wherein can be various elastic devices or member commonly used, most convenient and what be convenient to regulate is the mode that adopts the support structure of band spring member wherein, after being combined with suitable lifting regulating mechanism, can regulate its support height very easily, reach the purpose of adjusting the edge of a knife gap between moving, ledger-plate.Simultaneously, because will be connected with the knife rest of fixed blade is arranged on the elasticity support structure, when rotation along with rotor, the edges of a knife of moving, fixed two blades do fricting shearing cut the hole motion time, the elastic acting force of elasticity support structure can cushion the impulsive force when contacting between two edges of a knife greatly, the degree of wear of the edge of a knife be can reduce effectively, and vibration and noise reduced.

On this basis, be provided with in the mode that the axis direction with said this rotation rotor has suitable crossing angle as being arranged at the linear pattern cutting blade that rotates on the rotor, then " point " formula of moving, the way of contact of ledger-plate when fricting shearing moves changed into successively by present line contact can be contacted the extent of vibration noise in the time of can further reducing work.Said this crossing angle generally can take form that the axial midpoint at this rotation rotor is centrosymmetric for convenient.

Below foregoing of the present utility model is described further with example shown in the drawings.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.

Fig. 1: the structure of the utility model hole-cutting device

The A-A structure of Fig. 2: Fig. 1

As shown in the figure, in this sanitary tissue products segmentation hole-cutting device, frame 6 is provided with the fixed blade 3 that is connected in the discontinuous on the immovable support 4, and is provided with and can drives the rotor 1 that rotates through bearing 8 by actuating unit 7.Be equipped with on this rotation rotor 1 and can cutting the linear pattern cutting blade 2 in hole by mutual fricting shearing motion through the enterprising disconnected dotted line shape of the vertically hung scroll shape toilet paper in its gap in the ranks with fixed blade 3 edges of a knife.Its immovable support 4 is connected with elasticity support structure 5 on being arranged at frame 6 through supporting structure 9.The structure of this elasticity support structure 5 is for being provided with stage clip member 10 in its support seat, supporting structure 9 form on this support seat that matches with stage clip member 10, and through between the support seat of stage clip member 10 and this support structure 5, be provided with the screw type lift adjustment handwheel 11 of the elasticity support height that is used to regulate supporting structure 9 at supporting structure 9.Be arranged at the linear pattern cutting blade 2 that rotates on the rotor 1 and be provided with in the mode that the axis direction with this rotation rotor 1 has the crossing angle of the form that the axial midpoint at this rotation rotor 1 is centrosymmetric, its angle generally gets final product at 1 °～2 °.
