Description

A kind of automatic folding device of case binder

Technical field

The utility model relates to corrugated carton bonder technical field, is specifically related to the control device of corrugated case in folding process.

Background technology

Case binder is a kind of equipment using in carton manufacturing.Along with economic sustainable development, in society, all trades and professions all need to use packed in cases, especially increasing to the demand of corrugated case, a lot of enterprises have all been used pipelining, thereby require also more and more higher to the geometric accuracy of binding paper box moulding, in some industry, as industries such as tobacco, pharmacy, because its mechanization degree is high, to the dimensional requirement of carton, must there is the slightest difference hardly, otherwise can affect pipelining, greatly lower efficiency.Folding of corrugated case, bonding, to be folded to through the cardboard of 180 degree states 90 degree, and then be forced into the such process of 0 degree, traditional corrugated case case binder, the whole folding process of corrugated case is all to complete under the state pinching at the continuous turnup of belt, at case binder, a pair of belt is each side set, make corrugated board by starting 180 degree when folding until 0 degree while completing, all under belt effect, inwardly turnup and lower belt clamp send twist, in pinching movement, complete folding work simultaneously, whole process is carried out continuously, once complete, do not pause midway.In this process, corrugated board is subject to the active force of belt, to infolding, belt can only produce at the front end of cardboard traffic direction contacting of point or line with cardboard, can not produce plane contact, thereby make folded cardboard discontinuity, broken line produces dislocation, forms on " fish tail "; Folding belt mostly is flat belt, its pinching cardboard should horizontal movement turnup compressing cardboard is inwardly folding again, belt has good pliability, and corrugated board flexibility is poor, and belt inner side is due to turnup inward turning, horizontal movement speed has produced the decomposition of inward direction, thereby lag behind the cardboard speed of service, be subject to force direction and the actual folding direction of carton of folded cardboard produce hysteresis deviation, can not coincide, thereby make carton folded seam produce uncontrollable larger mistake, i.e. price scissors.Application number is to disclose a kind of automatic corrugated case bonder in 200920110927.5 utility model patent, 200910094095.7 patent of invention in a kind of carton interior diameter controller of corrugated carton bonder is disclosed, they are to the conveying in corrugated case production process, fold and done a lot of improvement, emphasis is the conveying of cardboard and the folding process from 180 degree to 90 degree, its external diameter, internal diameter is all well controlled, but the folding process from 90 degree to 0 degree, remain and adopt the continuous scrolling policy of belt folding, it is low early and high after that belt is, pre-small post-large splayed setting, force way between belt and cardboard is that point is stressed, carton enters the folding position of belt compressing, only have the point contacting with belt at first stressed, namely the forward part of carton is stressed, and cannot be stressed by rear section, belt is in the process pressing down, carton is anterior compacted naturally, and rear section open form becomes " fish tail ".As long as the mode set up box that adopts the continuous turnup of belt to pinch; flexible difference and the price scissors of this cemented side seam just cannot be effectively controlled; production for little error, high accuracy carton; can only rely on manual stick box to complete; labour intensity is large, and staff is very arduous, and cost is high; production efficiency is low, cannot meet the Production requirement of Packaging Industry scale, automation.

Utility model content

The utility model person technical problem to be solved is; a kind of directional automatic folding device of corrugated case case binder is provided; can realize directional automatic folding; replace traditional continuous turnup of belt folding; reduce the price scissors that carton produces in folding process; make corrugated case obtain physical dimension accurately, meet the Production requirement of Packaging Industry scale, automation.

In order to solve the above technical problem, the automatic folding device of a kind of case binder of the utility model, comprise platen assembly, described platen assembly comprises folding substrate, folding arm, sliding axle and the pressboard connecting in turn, described folding substrate is arranged on the upper end of the outer side mark pedestal of corrugated carton bonder, described folding substrate is connected with rotary pin shaft with bearing with folding arm, described sliding axle is assemblied in the sliding eye of folding arm end and is slidably connected with folding arm, and pressboard is fixedly connected on sliding axle end; Described folding arm approaches inner side, folding substrate place and is provided with positioning molding groove.

As improvement, on sliding axle described in the utility model, be provided with spring.

Directional automatic folding device described in the utility model applies to corrugated carton bonder, to folding of corrugated case, from 180 degree, be folded into 90 degree again to 0 degree, by people for before being divided into, rear two parts, from 180 degree, be folded into the folding leading portion of 90 degree and by 90 degree, be folded into the folding back segment of 0 degree, at folding leading portion, the external diameter of carton and internal diameter are controlled by outer side mark and the interior diameter controller of corrugated carton bonder, directional automatic folding device described in the utility model is installed on the part that is folded into 0 degree by 90 degree, fold back segment, carton is at folding back segment, just under the control of the automatic folding device of the utility model corrugated carton bonder, complete folding work.At folding arm rotation heel, be that folding arm approaches inner side, folding substrate place, be provided with positioning molding groove, when folding arm inwardly rotates to 0 degree by vertical 90 degree states, positioning molding groove is inwardly rotation from lower to upper also, match with the angular speed of folding cardboard rotation, when folding cardboard to 0 is spent, foldable formed carton is positioned in the parallel in opposite directions positioning molding groove in the corrugated carton bonder left and right sides, carton does not have abducent space, can accurately control carton is folded into 0 and spends outward extending error in journey, make width and the depth of parallelism of binding paper box seam obtain precise positioning, do not produce price scissors and " fish tail " phenomenon.Pressboard described in the utility model is fixed on sliding axle, and the compression spring being arranged on sliding axle regulates the intensity of pressure of pressboard automatically according to the thickness of carton, avoid damaging by pressure corrugated board.Automatic folding device described in the utility model, by eccentric cam through-drive eccentric cam, rotated, the power resources of eccentric cam shaft can have various ways, Tathagata is carried the mechanical synchronization transmissions such as gear, sprocket wheel, Timing Belt of carton folding movement from case binder, also the independent Synchronous Transmission of SERVO CONTROL motor all can complete.

The beneficial effects of the utility model: owing to having used the above structure, the utility model automatic folding device, can make corrugated case in folding process, from 90 degree states to 0 degree directional automatic folding, replaced the continuous turnup of traditional belt folding, by the point in traditional carton folding process stressed change into parallel, plane is stressed, lifting surface area is large, stress equalization; Set up box moves according to determining direction under the control of pressboard and positioning molding groove, carton does not have abducent space, can make width and the depth of parallelism of binding paper box seam obtain precise positioning, do not produce price scissors and " fish tail " phenomenon, make corrugated case obtain physical dimension accurately, meet the Production requirement of Packaging Industry scale, automation; The utility model automatic folding device, for corrugated case production line, can say the manufacturing revolution of corrugated case, has extraordinary development prospect.
