Summary of the invention is in order to solve the deficiency of existing facial tissue packer packaging product, the purpose of this utility model promptly is to provide a kind of mechanism that can stamp empty otch automatically on the paper handkerchief packing, it is more convenient to make that the customer uses, and effectively improves product market competitiveness.
The technical scheme that realizes the utility model purpose is such:
The empty cutting mechanism of a kind of facial tissue packer is characterized in that: described empty cutting mechanism comprises that void cuts portion, transmission device, position adjusting mechanism, and described void is cut portion and linked to each other with transmission device, and described position adjusting mechanism links to each other with transmission device.
The described void portion of cutting comprises empty cutting knife, empty cutting knife lower slide and empty cutting knife upper tool post, and empty cutting knife is installed on the empty cutting knife upper tool post.
Described transmission device comprises synchronous pulley, original synchronous pulley, band and belt tension mechanism synchronously, has guide wheel in the belt tension mechanism, band is installed on synchronous pulley and the original synchronous pulley synchronously, belt tension mechanism is arranged on the side top of described synchronous band, and synchronous pulley is connected with empty cutting knife upper tool post.
Described position adjusting mechanism comprises deflector roll, deflector roll, deflector roll and regulates screw mandrel, and described deflector roll, deflector roll and deflector roll are installed in respectively on the jockey pulley retainer, this jockey pulley retainer be provided with bar hole and, deflector roll is installed in the bar hole.
Described deflector roll can be along the length direction sway of deflector roll in bar hole, and mobile range is-35mm~+ 35mm.
The empty cutting mechanism of the utility model can be installed on original facial tissue packer, to be with an end to be enclosed within on the wrapping machine on original synchronous pulley synchronously, synchronously the other end of band is enclosed within on the synchronous pulley in the empty cutting mechanism of the utility model, synchronous pulley in the empty cutting mechanism is installed on the empty cutting knife upper tool post, by the empty cutting knife upper tool post of synchronous pulley transmission, thereby driving empty cutting knife rotates, make empty cutting knife velocity of rotation synchronous with the drive pulley velocity of rotation of packing board, board packing one bag paper handkerchief, empty cutting knife revolves and turns around, and guarantees that the stationkeeping of virtual tangent on the paper handkerchief packing is constant.Be installed in guide wheel in the belt tension mechanism of synchronous band side top and can move up and down and compress synchronous band, prevent that slipping of the belt is lax, guarantee the particularity of transmission.
Three deflector rolls that are installed on the jockey pulley retainer enter the packing board in order to the guiding packaging film, regulate screw mandrel and can change one of them movable deflector roll position in the strip shape hole, adjusting range is-35mm~+ 35mm, thus the position of virtual tangent on the paper handkerchief packing can be regulated.
The utility model action principle is:
1. pass through to be with synchronously the synchronous pulley that drives in the empty cutting mechanism by the original synchronous pulley on the wrapping machine when wrapping machine is started shooting;
2. drive empty cutting knife upper tool post by the synchronous pulley in the empty cutting mechanism;
3. the empty cutting knife that is installed on the empty cutting knife upper tool post is followed empty cutting knife upper tool post rotation, and next empty otch is once stayed in every rotation on the paper handkerchief packaging film, and empty cutting knife upper tool post rotative speed and board be (by synchronous band and synchronous pulley control) synchronously;
4. regulate deflector roll in the position of elongated hole with regulating screw mandrel when empty incision site departs from, the position of the empty otch of scalable makes empty incision site in desirable position like this.
The empty cutting mechanism of the utility model makes that facial tissue packer is able to stamp dotted cut on the paper handkerchief packing, tears conveniently when product is used, and has promoted the competitiveness of product in market.

The specific embodiment is convenient to understand the utility model for making your inspector and the public, below in conjunction with drawings and Examples the specific embodiment of the present utility model is described in detail as follows:
Fig. 1 is the front view of the empty cutting mechanism of the utility model, Fig. 2 is the lateral plan of Fig. 1, be with 8 one headgears synchronously on the original synchronous pulley 10 of packing board, the other end is enclosed within on the synchronous pulley 9 in this empty cutting mechanism, belt tension mechanism 11 is arranged on synchronously with above 8 the side, can compress and be with 8 synchronously by adjusting guide wheel 14 in the belt tension mechanism 11 up and down, make be with synchronously 8 non-slip.Empty cutting knife 1 is installed on the empty cutting knife upper tool post 3, and empty cutting knife upper tool post 3 is installed on the empty cutting knife lower slide 2, and empty cutting knife upper tool post 3 can rotate, and synchronous pulley 9 is fixed on the empty cutting knife upper tool post 3.
Deflector roll 4~deflector roll 6 is fixedly mounted on the retainer 7, this jockey pulley retainer 7 is provided with bar hole 12,13, deflector roll 4 is installed in the bar hole 12, deflector roll 5 is installed in the bar hole 13, deflector roll 5 can be along the length direction sway of deflector roll 5 in bar hole 13, and mobile range is-35mm~+ 35mm.
Regulate screw mandrel 15 1 ends and be installed on the jockey pulley retainer 7, the other end connects deflector roll (5).
During the facial tissue packer start, by original synchronous pulley 10 by being with 8 to drive synchronous pulleys 9 synchronously, drive empty cutting knife upper tool post 3 by this synchronous pulley 9, at this moment empty cutting knife 1 is followed empty cutting knife upper tool post 3 rotations, rotative speed is synchronous with the packing board, this can be by synchronous band and synchronous pulley control, and every rotation once promptly stays an empty otch on the paper handkerchief packaging film.With regulating screw mandrel 15 positions of adjusting activity deflector roll 5 in bar hole 13, promptly the empty otch of scalable position on the packaging makes empty otch in desirable position when empty incision site departs from.
