Background technology
Early stage umbrella cover printing is that the pure craft of a slice a slice is finished by operative employee hand-held silk-screen framework and cutter on a fixing workbench.This mode, because it is the operative employee need ceaselessly walk about before workbench, not only consuming time but also consume power.
Application number is that 2006100533618 patent application discloses a kind of semi-automatic silk-screen machine, the mode that this invention adopts conveyer belt to transmit changes " lining transmission " into " people walks about " in traditional umbrella cover dyeing process, each operative employee only needs to repeat to finish same operation at the station of oneself, and need not to walk up and down along workbench.Both save the time, reduced operative employee's labour intensity again.But, because need the hand-held cutter of operative employee to wait by machine, manually realize the lifting and the whereabouts of silk-screen framework, and finish and expand the ink print action.Still exist the inequality and the not first-class problem of hand-printing pressure of manual shop China ink.And in the screen printer of the present invention, the mode that still adopts single umbrella sheet to print one by one waits to print the paving of umbrella sheet and the recovery of seal back all needs the special messenger to finish by hand.Bring certain restriction to saving human cost, umbrella sheet speed of pasting and the positional precision further raising that also seriously restricting umbrella production efficiency in addition.
Application number is that the patent application of 200610155200X improves on the basis of foregoing invention, has designed a kind of silk-screen framework with automatic printing functionality, touches a series of defectives that the manual silk-screen action of determining brings.But the mode of loading and unloading has still kept the characteristics of foregoing invention.
Summary of the invention
The present invention will solve is that loading and unloading are wasted time and energy in the existing umbrella cover screen printer, and the low problem of precision again aims to provide a kind of long width of cloth umbrella cover screen printer of automatic loading/unloading.
The technical scheme that addresses the above problem employing is: a kind of long width of cloth umbrella cover automatic screen printer, comprise top establish the frame of workbench, head and the tail two transmission rollers, and being sleeved between the initial and end roller and outer surface is provided with " O " type conveyer belt of viscose glue, described first roller is by Motor Drive.Described workbench top is provided with cocainine seal framework along its length.It is characterized in that also being provided with feed mechanism and receiving mechanism at described frame tail end.
Described feed mechanism mainly comprises lining frame and feeding roller, and described lining frame is provided with the detachable lining mandrel that is used for suit lining volume.Described lining volume can simply be sleeved on the lining mandrel, loading and unloading are more convenient like this, but for not having bigger left-right deviation after making the lining upper table, answer the length of the described lining mandrel of appropriate design, to move axially the space on the mandrel very little so that lining twists in.The adjustable block of two axial locations perhaps is set on described lining mandrel twists in position on the lining mandrel to limit lining.Preferably the lining volume is fixed on the described lining mandrel, realizes the lining supply by designing special lining mandrel tumbler.Herein, lining volume fixing can be by improving above-mentioned two blocks, thereon or set up the fine setting clamp module on one of them and just can reach good fixed effect.The rotatable of described lining mandrel detachably is provided with structure again, can adopt and not be in the mood for bearing block, and its structure is that one group of left and right, following three bearing is installed respectively on the riser of lining frame both sides.Described lining mandrel two ends are placed between three axles and get final product.
Described feeding roller is arranged on described tail roller rear, and is driven by a driving belt by described tail roller, does the rotation synchronous with the tail roller.In the one side, be arranged side by side with it one adjustable and between it lining of distance compress roller.The feeding roller its role is to lining be clamped, so that can be pulled out lining when rotating from the lining frame with the feeding roller.Herein adjustable be meant when loading lining, can regulate compress that roller makes it and the feeding roller between form a gap so that lining therefrom passes.This function also can realize by the feeding roller, is about to feeding and is designed to adjustable.For reach good compress effect be preferably in the feeding roller and or compress roller surface and establish one deck soft material, as rubber etc.
When loading lining, wait to print lining top and come out to pass earlier described feeding roller and compress between the roller from the lining frame, extend to tail roller top then and paste labor with conveyer belt, start first roller power set, conveyer belt drive lining top moves ahead.At this moment, for realizing follow-up wait to print lining and conveyer belt stickup, the upper-lower position of described feeding roller is lower than the tail roller, follow-up like this lining then with work top on lining form a downward knuckle, the tensile force of front and back is pasting lining on the conveyer belt of nature just.Realize above-mentioned effect, can also adopt between feeding roller and tail roller, to add the mode that lining overlays roller and realize that in like manner, the described upper-lower position that overlays roller also need satisfy the condition that is lower than the tail roller.
Described receiving mechanism mainly comprises the detachable rewinding mandrel that is arranged on the rewinding frame and the drive system at intermittence of described collecting shaft, described rewinding mandrel be used for suit and fixedly rewinding roll up.Two adjustable rewindings of axial location are set on the described rewinding mandrel roll up fixedly fixture block.Described rewinding mandrel intermittently drive system comprises: motor, worm gear case, frictional disk, driving gear, friction pushing tow assembly, driven gear.Its power transfer path is: the rotation of described motor is passed to worm gear case by belt, pass to described frictional disk by machine with chain through the worm gear case break-in with after slowing down, described frictional disk is installed on the jackshaft parallel with described rewinding mandrel with friction pushing tow assembly successively side by side with described driving gear, because the pushing tow assembly leans driving gear on frictional disk, therefore, frictional disk has just been passed to driving gear by frictional force with rotation.Described driving gear meshes with the described driven gear that is fixed on the rewinding mandrel again, and final, described rewinding mandrel has been realized rotation.In this process, by the frictional force transmission, and frictional force is a kind of relative power between described frictional disk and the driving gear, and when driving tooth wheel dropping limit is excessive, frictional disk can't drive its rotation.So just, realized the rotation at intermittence that rewinding mandrel and printing process are synchronous.Described friction pushing tow assembly can be adopted the structure of retainer plate and compacting ring cooperation goring push spring, and the axial location of wherein said retainer plate on jackshaft fixed.As improvement, on described frictional disk, adorn detachable friction plate, so that change behind the friction disc wear with the contact-making surface of described driving gear.
Intermittently in the drive system, described frictional disk, described driving gear and the mounting means on jackshaft can have a variety of at the rewinding mandrel, at first, about three's axial location relation, can select driving gear or grinding disk be positioned at other both in the middle of.Secondly, about rotation relation, when employing turns jackshaft, can select driving gear or grinding disk to be fixed on the jackshaft, perhaps the two is not all fixed with jackshaft.When adopting fixedly jackshaft, described driving gear and grinding disk all need be installed by bearing.
As a further improvement on the present invention, add Damping rolling cylinder and reversing bar between described lining mandrel and feeding roller, because the rotation of lining mandrel is very flexible, after walking to expect, the lining volume can be because a part of lining of the many releases of inertia at every turn.Lining between lining frame and feeding roller is because loose and easy swing in this case, may wander off when lining enters the feeding roller.The effect of described Damping rolling cylinder just is to stop lining to enter the feeding roller smoothly and compresses between the roller, and lining was evened up it before entering.Increase reversing bar and be intended to make lining circuitous,, increase it and hinder effect so that lining and damper rod contact area increase one of the other formation of Damping rolling cylinder.
Further improve as of the present invention again, also add Damping rolling cylinder before described rewinding frame, its effect is the same, and its effect is to make rewinding roll up more neatly.
The present invention changes for a long time and earlier cuts out the umbrella cover processing mode that afterwards prints, and by add lining feeding and receiving mechanism on the umbrella cover automatic screen printer, has realized the automation of umbrella cover printing completely.Cooperate the long paper lining to print, can realize that long-time unattended duty prints automatically, has saved human resources greatly.The mechanization material loading consistently needs only when beginning material loading most in addition, and the operative employee pastes lining precisely diligently, and follow-up printing process will keep very high accuracy, improve printing quality.And, avoided a large amount of frequent operations owing to no longer need the manual piecemeal material loading of staff, resultfully prevented problems such as the printing factor of merit of bringing because of error is low.
