Abstract

The utility model discloses an automatic recoverer for recovering print labels. The recoverer comprises a main shaft used for installing a label tube core, wherein the main shaft is rotationally installed on a base; one end of the main shaft is fixedly connected with a driven wheel; an end surface of the driven wheel and an end surface of the driving wheel are coaxial and opposite and are absorbed with each other through magnetic force; the driving wheel is connected with a driving device through a transmission mechanism. The recoverer can deliver force moment through absorption of magnetic force; when a printing machine stops, the driving wheel and the driven wheel may skid, the driving wheel is not required to stop running, therefore the control of the recoverer is more convenient; and the change of delivered force moment can not occur due to abrasion, therefore the transmission effect is more stable and reliable. Lubricating oil can be used as a medium between the driving wheel and the driven wheel to reduce the frictional force therebetween, so as to ensure the consistency in recovering labels.

Description

The automatic withdrawer of Print Label

Technical field

The utility model relates to a kind of and the matching used device of label machine, is specifically related to a kind of automatic withdrawer of the synchronous backrush of label that can print rolling.

Background technology

In automatically identification industry, behind a large amount of label printings, all be manually printed label roll rolling, efficient is very low like this, and label is easy to workman's hand is scratched.The release of automatic withdrawer is just arranged afterwards, and synchronous for the printing action realization of energy and chopping machine, the form of withdrawer roughly has two types automatically, and a kind of is to control drive of motor with sensor, and another kind is to use the friction force transferring power.Preceding a kind of more inconvenience that has in use, the back is a kind of because of being the friction force effect, and loss easily after use a period of time descends effect.

The utility model content

The technical problems to be solved in the utility model provide a kind of can be better and the chopping machine automatic withdrawer of Print Label of coupling synchronously, to overcome the above-mentioned defective of prior art.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the automatic withdrawer of a kind of Print Label, comprise a main shaft that is used to install the label tube core, described main shaft is installed in rotation on the support, follower of an end captive joint of described main shaft, the end face of follower and the end face of a driving wheel are coaxial relative and by the adhesive of magnetic force phase, described driving wheel is connected with actuating device by transmission device.

Preferably, on described follower, driving wheel opposing end faces, be separately installed with many group magnet and iron plate.

Preferably, described actuating device is a motor.

Further, a belt wheel is installed on the described motor shaft, is connected by being with synchronously between described belt wheel and the driving wheel.

Preferably, the two ends of described main shaft are equipped with baffle plate.

Preferably, described support comprises a base plate and a frame that is fixed on the base plate, and the both sides of frame are provided with cover plate, and described driving wheel, follower, transmission device and actuating device are installed in the frame.

Further, the top of described frame is provided with handle.

Preferably, scribble lubricating oil on described follower, the driving wheel opposing end faces.

The beneficial effects of the utility model are: when the printer prints label, the attraction by magnetic force between driving wheel and the follower comes carry-over moment; When chopping machine stops, can skidding between driving wheel and the follower, and not need the driving wheel stall, so the utility model is easier in control; The moment that can cause because of wearing and tearing transmitting does not change, so the transmission effect is more reliable and more stable.Between driving wheel and follower, can make medium, reduce mutual friction force, guarantee the conformability of label recovering effect by lubricating oil.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The specific embodiment

As shown in Figure 1 and Figure 2, the automatic withdrawer of a kind of Print Label of the utility model comprises a main shaft 1, on the main shaft 1 the label tube core can be installed, and reclaims printed label to reel.The two ends of main shaft 1 are equipped with baffle plate 11, and the label tube core is between two baffle plates 11.

Main shaft 1 is installed in rotation on the support, and this support comprises a base plate 10 and a frame 4 that is fixed on the base plate 10.The both sides of frame 4 are provided with cover plate 6, thereby are combined into an osed top casing with frame 4, and follower 2, driving wheel 3, transmission device and actuating device are installed in the frame, and driving wheel 3 is connected with actuating device by transmission device.The top of frame 4 is provided with handle 12, so that use grasped.

Follower 2 is fixedly connected on an end of main shaft 1, driving wheel 3 is bearing on the pedestal 5, the end face of follower 2 is oppositely arranged with the end face of driving wheel 3 is coaxial, and be pulled together by magnetic force, this magnetic force adhesive can realize in several ways, one of them is made by permanent magnet such as follower 2 and driving wheel 3, and another is made by permeability magnetic material; Perhaps they are made by permanent magnet, but opposite pole is relative.A kind of optimal way that present embodiment adopts is, follower 2 and driving wheel 3 are made by common metal pure iron and plastics respectively, it is corresponding to be inlaid with the iron plate face that keeps on magnet and the follower on the end face of driving wheel 3, shown in Fig. 3,4, on the end face of driving wheel 3, inlay polylith permanent magnet 31, and keep pure iron sheet 21 at the relative position of follower 2 end faces, thereby can make them pass through the adhesive of magnetic force phase, and can regulate the moment size of transmitting continuously with the size of the contact surface between them.

In order more to be expressly understood the utility model, the following describes principle of work of the present utility model.

The rotating torque of motor 7 outputs, through being with 8 to be delivered to driving wheel 3 synchronously, driving wheel 3 drives the follower 2 that is fixed on the main shaft 1 by magnetic force and rotates together, transmits corresponding moment, and main shaft 1 rotates and the label paper that discharges from chopping machine can be rolled up automatically.If suspended (being printer pause) by Roll Sushi (label paper), driving wheel 3 continues rotation, but follower 2 because of the resisting moment that suspend to produce greater than kinetic moment stall that magnetic force produced, just skid between driving wheel 3 and the follower 2, in case resisting moment is during less than kinetic moment, follower 2 can drive main shaft 1 again and begin rotation, begins the label paper of reeling.Friction force when skidding between driving wheel 3 and the follower 2 in order to reduce can be coated lubricating oil on their opposing end faces.

The big young pathbreaker of kinetic moment determines the tight ness rating of label backrush, therefore reasonably designs the size of magnetic force between driving wheel 3 and the follower 2, just can control the tight ness rating of label backrush.

Because transmission of power of the present utility model is the effect of adopting magnetic force, the printing action of energy and label machine is coupling well, when changeing, stopping the state switching, is not subjected to the influence of speed speed, therefore also can be useful under the situation of fast speed, reclaim label automatically.
