Abstract
The invention discloses a paper cutting unit comprising two feed rollers and two discharge rollers. The feed rollers fit each other; the discharge rollers fit each other. A cutting device is disposed between the feed rollers and the discharge rollers and comprises an upper blade and a rubber roller disposed right under the upper blade. The upper blade is disposed at the lower end of a rack vertically arranged. The rack is driven by a gear to move up and down. The gear is disposed on an output shaft of a motor through a coupling. Compared with the prior art, the paper cutting unit has the advantages that cutting position of paper is accurate, noise is low, and operating efficiency is high.
Description
Technical field
The present invention relates to a kind of paper cutter.
Background technology
Paper roll is cut into sheet and all can uses hand papercutter, hand papercutter has multiple, as above plug-in strip, the flail knife etc. that intermittently cuts of down cut; although during plug-in strip cut paper trimming to cut quality better, paper must stop, and cuts and could continue paper feeding; paper feeding speed can not be fast, and production efficiency is very low; Though flail knife can not stop paper feeding, the moment mechanical shock cut is comparatively large, easily causes the infringement of plant equipment and the pollution of noise, and the speed of paper feeding simultaneously can not be too fast, and scraps of paper length can not be too short, otherwise centre do not stop cutter time ask, cause cut paper length to be forbidden.
The rotating paper cutter of a kind of high accuracy automatic control disclosed in Chinese patent 201220003879.1, the rotating paper cutter of a kind of high accuracy automatic control, comprise paper advance mechanism and paper delivery mechanism, described paper advance mechanism is made up of two feeding-in rolls, be positioned at the paper roll entrance point of this paper cutter, described paper delivery mechanism is an exit roller, it also comprises paper cutting mechanism and little transport platform, described paper cutting mechanism is made up of upper slitter and lower cutter, between paper advance mechanism and paper delivery mechanism, described upper slitter is fixed in a rotating roller, and described lower cutter spacing, in the below of upper slitter, is fixed on a swing mechanism; Described little transport platform is positioned at the end of this paper cutter.Described swing mechanism is provided with a micro-adjusting mechanism.Be provided with blower mechanism at described paper delivery mechanism end, its quantity is two.The below of described little transport platform is provided with an air suction mechanism.
Although the rotating paper cutter of this high accuracy automatic control has the following advantages: 1, high accuracy; Utilize the scraps of paper error in length of our this hand papercutter cut-off knife to can be controlled within scholar 1 millimeter, diagonal error can be controlled within scholar 0.5 millimeter.
2, synchronous adjustment automatically; According to specific circumstances, the speed of paper in impregnated wire often will adjust, this just requires that each functional section all will have automatic adjustment, keeps synchronous ability, and this utility model has this function equally, it has the control system of oneself (as the logical calculated of inside, logic control etc.), simultaneity factor also can constantly detect main speed, and self-contr ol, oneself's adjustment, synchronous to ensure.
3, applied widely; The utility model have employed special cutter material and scientific and reasonable mounting means, add the swing of reliable micro-adjusting mechanism to lower cutter to locate accurately, therefore this equipment can carry out high-quality cutting to the impregnated paper of every square metre of 20-200 gram; More peculiar, this device can cut not only soft but also tough body paper, and the quality cut is also very high.When cutting, sound is very little, cuts close to one is quiet.
4, rationally carry; The scraps of paper conveying of this device have employed two cover blowing and a set of air suction mechanisms, and blowing can avoid curl damaged, realizes the object of flexible paper feeding; And air suction mechanism can make in course of conveying more smooth.Transportation section employs double speed conveying, first stage quick paper feeding, and second stage then utilizes air suction function that paper is fitted on belt to slow down, thus ensures that the scraps of paper impact the final stage of conveying is not spacing with stacking, and the scraps of paper accurately can be delivered to position.
But upper slitter is fixed in a rotating roller, lower cutter spacing is in the below of upper slitter, be fixed on a swing mechanism, need upper slitter and lower cutter to fit together the effect that just can complete cut paper completely when cut paper, slightly deviation, as: upper slitter is not rotated in place, and lower cutter does not swing and puts in place, and the edge of a knife of upper slitter and lower cutter just in time not to engage etc. situation all can cause cut paper failure.
A kind of Novel paper cutter disclosed in Chinese patent 201320189100.4, comprise frame and rack-mounted intake roller, rubber roller, also comprise paper cutting device, described paper cutting device is arranged in frame, be positioned at the rear end of intake roller and rubber roller, described paper cutting device comprises upper slitter and lower cutter, described lower cutter is fixed on lower slide, described lower slide is connected with frame, described upper slitter is fixed on upper tool post, described upper tool post is fixed on slitter shaft, and described slitter shaft is fixed in frame, and described slitter shaft is connected with cutter motor.Described lower slide tail end is provided with micromatic setting.Described upper tool post is board-like upper tool post.Described cutter motor is controlled by PLC.
Although this Novel paper cutter has the following advantages: have employed board-like upper tool rest structure, upper slitter and rotating knife general, the upper slitter of straight mouth, helical cuts can be installed, possess the exchange with rotating knife parts, saved the cost of client's updating apparatus, eliminate mechanical cam structure simultaneously, overall structure is simpler, compact, coordinates servo-control system, there is higher machining accuracy and flexibility, can significantly enhance productivity.
But need upper slitter and lower cutter to fit together the effect that just can complete cut paper completely, slightly deviation when cut paper, as: upper slitter is not rotated in place, and lower cutter is not adjusted to the right place, and the edge of a knife of upper slitter and lower cutter just in time not to engage etc. situation all can cause cut paper failure.
Summary of the invention
The present invention needs the problems referred to above solved to be for above-mentioned the deficiencies in the prior art, and provides a kind of paper cutter.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of paper cutter, comprise two feeding-in rolls cooperatively interacted and two exit rollers cooperatively interacted, paper cutting mechanism is provided with between feeding-in roll and exit roller, described paper cutting mechanism comprises upper slitter and is arranged on the rubber rollers immediately below upper slitter, described upper slitter is arranged on the lower end of the tooth bar that is vertically arranged, and described tooth bar is in the biography of gear
Action with under move up and down, described gear is arranged on the output shaft of motor by shaft coupling.
The direction of rotation of described rubber rollers is consistent with paper delivery direction.
The height that the height that described rubber rollers is arranged is arranged higher than that root feeding-in roll being positioned at below in two feeding-in rolls.
The height that the height that described rubber rollers is arranged is arranged higher than that root exit roller being positioned at below in two exit rollers.
