Description

Die-cutting device

Technical field

The utility model is related to printing mechanism fields, more specifically, it relates to a kind of die-cutting device.

Background technology

Tradition cross cutting say be printed matter post-production a kind of cutting process, die-cutting process can printed matter or its His paper products are carried out being fabricated to die-cutting rule version and be cut according to prior designed figure, to make the shape of printed matter no longer It is confined to straight flange right angle.The raw common die-cutting rule of tradition cross cutting is combined into mold cutting plate according to the pattern that product design requires, in pressure Under the action of, printed matter or other sheet blanks are rolled to the moulding process for being cut into required shape or cut mark.

The Chinese utility model patent of Publication No. CN202192844U discloses a kind of Intermittence type die-cutting machine, including machine Frame is led after being provided with unwinding unit, cross cutting front haulage unit, die cutting unit, cross cutting in the rack successively by page orientation Draw unit and rolling unit, die cutting unit includes upper and lower roller and attached blade on the surface thereof.

The Intermittence type die-cutting machine continuously can carry out cross cutting operation to band-like paper, can also by add put film unit and Press mold unit realizes the overlay film before cross cutting；But the Intermittence type die-cutting machine is in paper tape transmission process, due between paper and equipment Opposite friction is had, certain electrostatic can be accumulated on its surface, and paper tape exposure is in air, is easily stained with dust；When When viscous dust on paper is more, the quality after paper tape press mold will be had an impact.

Utility model content

For the deficiency that the prior art arrives, the utility model aim is to provide a kind of die-cutting device, has and exists to paper tape The effect of deashing before processing.

To achieve the above object, this experiment is novel provides the following technical solutions：

A kind of die-cutting device, including independently arranged unwinding unit, press mold unit, die cutting unit and rolling unit successively； It is provided with deashing device between the unwinding unit and the press mold unit；The deashing device includes rack, delivery platform With deashing tracheae；The delivery platform is both connected to the deashing tracheae in the rack, and the deashing tracheae is located at institute It states above delivery platform；On the peripheral wall of the deashing tracheae gas hole, the deashing gas are offered towards the delivery platform Pipe is connected with feeder.

So set, when passing through delivery platform by paper tape, the deashing tracheae for being connected to feeder is sprayed from gas hole Gas removes the dust on paper tape surface, to realize the purpose to paper tape deashing, improves press mold quality.

Further setting：It is provided on peripheral wall on the deashing pipe and to be abutted with by the paper tape of the delivery platform Bristle.

So set, being contacted with bristle when passing through delivery platform by paper tape, to coordinate to tape chart with deashing tracheae Face is dusted, to improve dedusting quality.

Further setting：It has been fixedly connected with snap ring on the peripheral wall at deashing pipe both ends, has been arranged on the snap ring There is fixed link, brush board is provided between two fixed links, the both ends of the brush board are rotatablely connected the fixed link；It is described Bristle is fixed on the brush board.

So set, by the way that the both ends for carrying the brush board of bristle are rotatably connected in fixed link, it is solid to bristle realizing While determining, because brush board is rotatable, reduces the resistance after bristle is contacted with paper tape, so that paper tape is passed through smooth.

Further setting：Axis hole is offered in the end of two fixed links, is provided in the both sides of the brush board slotting It is connected to the connecting shaft of the axis hole.

It is to realize brush board and consolidate so set, being plugged on by the connecting shaft of brush board both sides on the axis hole of fixed boom end The rotation connection of fixed pole.

Further setting：The sweep-up pipe being provided in the rack above the delivery platform, in the week Air admission hole is provided on wall；The sweep-up pipe is connected with air extractor.

So set, by the way that sweep-up pipe is arranged, the dust in its neighbouring air is absorbed, while siphoning away deashing tracheae in paper The dust that belt surface is blown afloat, prevents dust from falling on paper tape again, further increases deashing quality.

Further setting：The stabilization axis of play above and below when being rotatablely connected restricted paper tape conveying in the rack；Institute State between stable axis and the delivery platform that there are the gaps passed through for paper tape.

So set, by adding stable axis, make paper tape across the gap stablized axis and delivery platform, to prevent In deashing process the stability and transmission precision of paper feeding are influenced because paper tape is made to go up underdrive in transmission process for air-flow.

Further setting：The rolling positioned at delivery platform paper feed end and paper delivery end is rotatably connected in the rack Axis；The peripheral surface of the roller bearing is abutted with paper tape.

So set, being contacted prior to delivery platform with paper tape by the way that roller bearing is arranged, transition is played to delivery platform to paper tape It is used, prevent paper tape to be in direct contact the edge of delivery platform and scratch.

Further setting：The bar-shaped trough extended along paper feeding direction is offered on the table top of the delivery platform.

So set, by the way that bar-shaped trough is arranged in paper feeding plane, reduce the contact area with paper tape, to reduce paper The frictional resistance of band and paper feeding interplanar keeps the conveying of paper tape more smooth.

In summary：When passing through delivery platform by paper tape, the deashing tracheae for being connected to feeder is sprayed from gas hole Gas removes the dust on paper tape surface；It is contacted with bristle when passing through delivery platform by paper tape, to coordinate with deashing tracheae Paper tape surface is dusted, to improve dedusting quality；By the way that sweep-up pipe is arranged, the dust in its neighbouring air is absorbed, together When siphon away the dust that deashing tracheae blows afloat on paper tape surface, prevent dust from falling on paper tape again, further increase deashing quality.
