Description

A kind of strap break-proof protecting device on winder

Technical field

The utility model relates to straps to wind field, be especially a kind of anti-breaking protection of the strap on winder Device.

Background technique

Currently, strap (being called strapping) is relatively conventional in daily life and industrial circle, mostly by polypropylene, The materials such as PET polyester are made, suitable for carrying out bundle and package to the different object of weight.

It during the extrusion of strap, needs to carry out continuously shaped strap winding operation, and winds logical Chang Douhui uses winder.However, when winder carries out winding operation to strap, with the gradually increasing of winding disk body diameter Greatly, it conveys pulling force suffered by the strap come be also continuously increased, it is easy to the phenomenon that pulling apart strap occur.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of anti-breaking protection dress of the strap on winder It sets, can remain the strap stress equalization that conveying comes in the entire wrapup procedure of strap, avoid phenomenon of rupture Generation.

The technical solution of the utility model is to provide a kind of strap being used on winder having following structure Break-proof protecting device, including directive wheel, stay wire sensor, sliding sleeve and guide rod, the guide rod has two, and vertically sets Set, two guide rods are located at the feed side of Scroll, and are mounted on the side wall of rack by U-lag steel, the sliding sleeve with lead Connection is slided up and down to bar, the axis of the directive wheel and the axis of Scroll are parallel, and directive wheel is mounted on cunning by short axle It puts on, in the U-lag steel of lower part, drawstring is connect the stay wire sensor with sliding sleeve, the stay wire sensor and control Device electrical connection.

A kind of strap break-proof protecting device on winder described in the utility model, wherein on each guide rod It is arranged with rubber pad and helical spring, the rubber pad is located at the bottom of sliding sleeve, and the helical spring is located at the top of sliding sleeve.

A kind of strap break-proof protecting device on winder described in the utility model, wherein the rack Feed side is equipped with the feeding distribution mechanism that paper tube length direction of the strap along Scroll front for carrying out conveying is evenly distributed, institute Feeding distribution mechanism is stated at paper tube.

A kind of strap break-proof protecting device on winder described in the utility model, wherein the depiler Structure includes orientating box, screw rod, sliding block, sub-material item and the step for driving sliding block to slide along paper tube axis direction of open top Into motor, the sliding block is located in the cavity of orientating box, and the two sidewalls of sliding block and the inner sidewall of orientating box fit, the screw rod It being threadedly coupled on orientating box, and with sliding block, on the rack, the tail portion of shaft and screw rod connects the stepper motor dress, The feed side of the sub-material item is mounted on the top of sliding block by bracket, and the exit side of sub-material item rides upon on the outer wall of paper tube, The top surface of the exit side is equipped with the material path passed through for strap, and guiding runner is housed at the top of the feed end of sub-material item.

After using the above structure, compared with prior art, a kind of strap on winder of the utility model is anti-breaking Protective device has the advantage that when winding to strap, its front is ridden upon to the bottom of directive wheel first, then At traction to the paper tube of Scroll one end, the head of strap is followed closely on paper tube, subsequent start-up winder, is completed through manufacture Strap is constantly conveyed to paper tube, starts to carry out winding operation；When the pulling force that strap is subject to is slightly larger, sliding sleeve just will drive It moves upwards, and stay wire sensor changes then by the signal real-time delivery sensed to controller according to preset data The revolving speed of Scroll other end winding motor, to keep pulling force suffered by strap always consistent.It is clear that this is practical It is novel to be designed by this reasonable structure, the packing that conveying comes can be remained in the entire wrapup procedure of strap Band stress equalization substantially increases the qualification rate of product and the efficiency of winding so as to avoid the phenomenon of rupture of strap.
