Abstract
Rotating cross-section cutting means, including servo motor, and cut roller by what shaft coupling was connect with servo motor, the lower section for cutting roller is equipped with axial parallel bed plate therewith, the periphery for cutting roller has the screw type cutter at perforation both ends, the thread lead angle Φ of the screw type cutter is more than 80 degree, and the axial direction for cutting roller also has the compensation angle Θ equal with thread lead angle Φ with the paper feeding direction of paper product；When cutting roller rotation, the point contact type that screw type cutter constitutes paper product between the two along the upper edge of bed plate continuous moving cuts track, while being corrected when cutting by compensating angle Θ and cutting track to be allowed to holding vertical with paper feeding direction.Screw type cutter, with paper product point contact, it is small to cut noise when cutting；The paper cut out will not tilt；Individual length cut out can on-line control, do not have to shut down, production efficiency and product quality is greatly improved, has been greatly reduced production cost.
Description
Technical field
The utility model is related to paper cutting technology, in particular to rotating cross-section cutting means.
Background technology
The paper cutting device that the prior art generally uses, after the roll paper print of the paper products such as books and periodicals, cigarette case
Individual cutting means cut mostly uses transecting type greatly and cuts, including constitute Rotary cooperation cut roller and bottom roller, cutting
Blade parallel is fixed in the axial direction for cutting roller with screw and briquetting on roller.Meanwhile cutting the circle pressure that roller and bottom roller are constituted
Circle fit structure is additionally operable to assist to realize paper feeding, is sent into and is cut between roller and bottom roller when paper product, cuts roller and often rotate a circle i.e.
Cut one.
Above-mentioned cutting means in the prior art, due to blade with to cut roller axially parallel, when blade cut paper and paper product
Line contacts, and it is larger to cut noise, and blade abrasion aggravation is made to shorten the working life.Therefore it needs more frequently to shut down more tool changing
Piece causes production efficiency relatively low, every time compared with high rejection rate caused by shutdown also meeting.
Moreover above-mentioned cutting means in the prior art, one is cut because cutting roller and often rotating a circle, paper is cut out
Individual length cut is to cut the circumference of roller.Whenever replacing a kind of paper product of different length specification, a sanction is just needed to change
Roller is cut, it is poor for applicability, cause production cost higher.
Utility model content
The utility model provides a kind of rotating cross-section cutting means to overcome above-mentioned prior art shortcoming,
Mainly use the following technical solution.
Rotating cross-section cutting means, including servo motor, and roller is cut by what shaft coupling was connect with servo motor, it cuts out
The lower section for cutting roller is equipped with axial parallel bed plate therewith, and there is the periphery for cutting roller the screw type at perforation both ends to cut
The thread lead angle Φ of knife, the screw type cutter is more than 80 degree, and the paper feeding side of the axial direction and paper product for cutting roller
To also with the compensation angle Θ equal with thread lead angle Φ；Cut roller rotation when, screw type cutter along bed plate upper edge pair
The point contact type that paper product between the two constitutes continuous moving cuts track, while sanction is corrected when cutting by compensating angle Θ
Track is cut to be allowed to keep vertical with paper feeding direction.
Compared with prior art, the beneficial effects of the utility model are：
(1) it is small to cut noise when cutting with paper product point contact for screw type cutter；
(2) it is corrected by compensation angle Θ when cutting and cuts track, the paper cut out will not tilt；
(3) cut action by Serve Motor Control, individual length for cutting out do not influenced by the circumference for cutting roller and
Can on-line control, do not have to shut down, production efficiency and product quality is greatly improved, has been greatly reduced production cost.
The utility model is described further with embodiment with reference to the accompanying drawings of the specification.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram that roller is cut in the utility model.
Fig. 3 is the operation principle schematic diagram of the utility model.
Fig. 4 is the structural schematic diagram of bed plate in the utility model.
Specific implementation mode
As shown in fig. 1 to fig. 4, rotating cross-section cutting means, including servo motor 1, and pass through shaft coupling 2 and servo electricity
What machine 1 connected cuts roller 3, and the lower section for cutting roller 3 is equipped with axial parallel bed plate 4 therewith, the outer circle mask for cutting roller 3
There is a screw type cutter 5 at perforation both ends, the thread lead angle Φ of the screw type cutter 5 is more than 80 degree, and described cuts roller 3
Axial direction and the paper feeding direction of paper product 6 also there is the compensation angle Θ equal with thread lead angle Φ；When cutting the rotation of roller 3, spiral shell
The point contact type that rotation type cutter 5 constitutes paper product 6 between the two along the upper edge of bed plate 4 continuous moving cuts track, together
When by compensate angle Θ is corrected when cutting cut track be allowed to holding it is vertical with paper feeding direction.
Rotating cross-section cutting means in the above embodiment keep line with when blade cut paper in the prior art with paper product
Contact cuts mode difference, screw type cutter 5 when cutting with 6 point contact of paper product, therefore cut noise to be much smaller than it is existing
There is technology.Although the axial direction for cutting roller 3 and the paper feeding direction of paper product 6 have inclined compensation angle Θ, mended due to passing through
Repaying angle Θ can keep its holding vertical with paper feeding direction as the rotation amendment for cutting roller 3 cuts track just when cutting, because
This paper cut out will not tilt, and the transecting type finally obtained like the prior art is cut.Unlike the prior art another
Any is, cuts paper feeding stroke of the roller 3 independently of paper product 6, cut action by servo motor 1 control cut roller 3 rotate into
And screw type cutter 5 is made to meet cooperation with 4 phase of bed plate to realize, the two will not be formed when not meeting cooperation mutually and be cut, and will not be influenced
Paper feeding stroke, therefore individual length that cuts out of paper product 6 is no longer influenced by the circumference for cutting roller 3, and servo motor 1 is only passed through
The on-line control of individual length can be realized in the rotation speed change that control cuts roller 3, does not have to shut down, production efficiency is greatly improved
And product quality, it has been greatly reduced production cost.
Preferably, the length of the bed plate 4 is matched with the length for cutting roller 3, and cross section rectangularity, upper edge tool
There is the oblique angle 41 met to screw type cutter 5.Oblique angle 41 can slightly lift the paper product 6 at this, it is made preferably to coordinate spiral shell
Rotation type cutter 5, is preferably cut quality.
Optionally, the outer rim of screw type cutter 5 and the upper edge of bed plate 4 keep 0.005-0.015mm clearance fits.This
Gap range, the outer rim for being not only avoided that screw type cutter 5 and the upper edge of bed plate 4 are collided, but also can guarantee that paper product 6 is effectively cut
It disconnects.
For those skilled in the art, it can be obtained according to the revealed structure of the utility model and principle other each
Kind is corresponding to be changed and deforms, and all these change and deform the protection category for belonging to the utility model.
