Description

Paper feed part is provided with the print fluting machine of all-servo paper feed system

Technical field

The utility model relates to a kind of package packing machine, relates in particular to the print fluting machine that a kind of paper feed part is provided with all-servo paper feed system.

Background technology

Print fluting machine is widely used a kind of package packing machine, its primary structure as shown in Figure 1, comprise front edge paper feed unit 11, paper feed unit 12, a plurality of printing element 13, fluting unit 14 and die cutting unit 15, each unit is unified cooperating in harmony under the effect of power-equipment and transmission mechanism, finishes paper feeding, printing, fluting and the cross cutting of cardboard jointly.The paper feed part that front edge paper feed unit wherein and paper feed unit are formed is provided with all-servo paper feed system, and this system adopts four independent servo motor, drives respectively under three groups of paper pushing rollers and a paper feeding and rolls roller; And adopt all-servo paper feed system of the common composition of two groups of vacuum adsorption box, take charge of transfer function in cardboard.The paper feed part of prior art, its primary structure as shown in Figure 2, it comprises rolls the paper advance mechanism that

roller

23,25 is formed by three groups of rollers 26, cam box 261, front edge paper feed mechanism that vacuum adsorption box 262 is formed and by two groups of paper feedings are upper and lower between the paper feed part both

sides wallboard

27,28 that is installed in print fluting machine, form a unified paper feed system, take charge of transfer function in cardboard.Wherein cam box 261 links to each other with main drive gear 21 transmissions, and gives three groups of rollers 26 by gear train 263 with transmission of power, and vacuum adsorption box 262 is responsible for cardboard is adsorbed on the roller 26, forms the front edge paper feed unit paper feeding; In addition, two groups of upper and

lower rollers

23,25 that roll of paper feeding are by two groups of last lower gear 231,251 engaged transmission that link to each other therewith; Roll between the roller group by carrier gear 232 respectively with under roll roller gear 231 engagements, first group following carrier gear 22 and the main drive gear engaged transmission of roller gear 231 by being meshed with it of rolling forms the paper feed unit paper feeding; Behind the main electric motor starting, main drive gear respectively by cam box with under roll roller gear, transferring power is finished paper feeding.

Along with development of technology, the productivity ratio of the printing of print fluting machine, fluting, cross cutting is more and more higher, now just with 60 speed development of per minute to 250 of per minutes, the raising of this productivity ratio, certainly will bring the frequency that requires paper feeding to accelerate, the precision of paper feeding is higher, be less than every of 0.5mm/, and it is also very high to the quality requirement of paper, the angularity that requires cardboard is less than below the 20mm, and paper jam phenomenon takes place during paper feed the excessive warpage of cardboard easily, influence the quality of carton moulding, also reduced speed of production simultaneously.In order to accelerate paper feeding speed, must reduce the upper and lower gap of rolling roller of paper feeding, increased the grinding pressure that draws paper; Like this, just reduced the anti-pressure ability of carton widely, also increased the generation of paper jam phenomenon simultaneously, waste product increases; In addition, gear pair is too much, causes roller and rolls roller, rolls roller and roll not waiting of linear velocity between roller, and the upper and lower paper that draws of cardboard is inconsistent, and cardboard breaks.Going down for a long time seriously to influence the production of carton.Thereby need a kind of raising that neither influences speed of production, and do not influence the anti-pressure ability of carton again, satisfy the needs of high speed development, existing method and technology has been the requirement that can not be fit to market, the user has strong complaints.

Summary of the invention

The purpose of this utility model is the print fluting machine in order to provide a kind of paper feed part to be provided with all-servo paper feed system, and is fast because of paper feeding speed to guarantee print fluting machine in the process of paper pushing board, causes paper jam phenomenon; The gap of rolling roller because of paper feeding is upper and lower is too small, causes the anti-pressure ability of carton to descend; Because of roller and roll not waiting of linear velocity between roller, crowfoot cracks phenomenon that causes cardboard etc. has a strong impact on the solution of cardboard quality.To guarantee accomplishing that paper feeding speed is fast, it is good to go out paper quality, has improved to maximum work quality and precision.

Technical solution adopted in the utility model is: a kind of paper feed part is provided with the print fluting machine of all-servo paper feed system, mainly comprises front edge paper feed unit, paper feed unit, a plurality of printing element, fluting unit and die cutting unit.The paper feed part that described front edge paper feed unit and paper feed unit are formed is provided with all-servo paper feed system, comprise that controlling a paper pushing roller group respectively separately separately by three servomotors rotates, and below roller set, be furnished with the front edge paper feed unit that a vacuum adsorption box is formed; Also comprise by rolling the roller running in paper feeding of a servomotor control, and above rolling roller, is furnished with the paper feed unit that a vacuum adsorption box is formed, it is characterized in that: each servomotor is connected with an encoder by lead, the encoder gear that this encoder links to each other by fixed conveyor, with the travelling gear engaged transmission, and obtain the linear velocity information that rolls roller under the paper feeding that links to each other with the main transmission engaged transmission, feed back to independent servo motor separately again, servomotor is information adjusting rotating speed separately in view of the above, make roller separately, the linear velocity of rolling roller under the linear velocity of rolling roller in the paper feeding and the paper feeding is synchronously consistent all the time, the suction-operated of two responsible two paper feed unit cardboards of vacuum adsorption box.
