Abstract

The utility model discloses a large-size automatic picture changing advertisement machine, on the upper end and under a floorstand, an upper and a lower scroll are arranged respectively, the two ends of a drape which is printed with a plurality of advertisement pictures are rolled on the upper and the lower scroll; two pull ropes winded to the positive and opposite direction are provided on the rope rollers of a windlass with two rope rollers, one end is fixed on the respective rope rollers, the other end is winded on the upper and the lower rope roller respectively through a crown block, the winding direction is reverse to the rolling direction of the drape on the corresponding roller; a tensioner is arranged between two corresponding crown blocks which the lower pull rope crosses through. Because the winding directions of the upper and the lower pull rope are reverse, the tensioner strains the pull rope under the action of gravity, which makes the drooping drape roll on the lower roller; as for that, the drooping and folding won't happen in the advertisement picture rolling up and down crossly, which won't impact the demonstrating effect.

Description

Large-scale from moving picture advertisement device

Technical field

The utility model belongs to advertisement machine, the especially a kind of large-scale advertisement machine that can move picture certainly.

Background technology

The advertisement machine of moving picture certainly of Chu Shouing is in window back, advertisement kitchen in the market, twist in respectively on the two parallel up and down spools with the top long door curtain made of cloth two ends that are printed on multi-picture, the homonymy termination of its diaxon is connected with the belt pulley of band clutch coupling respectively, and link to each other with the reductor of motor by belt, one on clutch coupling separates a combination on the rotating of control motor and two the spool spindle noses, drive one of them spool respectively, another spool is by door curtain made of cloth traction passive rotation, because two spools with how many its external diameters that lick the door curtain made of cloth are in the variation, when a separated spool of clutch coupling is in the relieving state and is affected, because its deadweight effect, make the door curtain made of cloth loosen the folded phenomenon of sagging generation, influence the bandwagon effect of picture, generally be equipped with the parts that increase its rotary resistance as spring and so in roller tube end, such structure can also adapt to small-sized advertisement machine, if make about 6 meters or above advertisement machine, the door curtain made of cloth is conducted oneself with dignity greatly to be increased, have at kilogram up to a hundred, with the base part of spring increase resistance little cannot keep under control spool, resistance is big and easily the door curtain made of cloth is torn, and can't realize the operate as normal that large-screen wide is accused.

Summary of the invention

In order to solve the operate as normal of large-scale automatic picture-changing advertising machine, make the door curtain made of cloth that is printed on several advertisement pictures be unlikely because of its deadweight sagging, the folded bandwagon effect that influences of the door curtain made of cloth appears when causing picture rolling, the technical solution of the utility model is: in the upper end and the bottom of a stand, respectively with bearing have be parallel to each other on, lower winding shaft, at spool homonymy spindle nose, be installed with the winding up roller of restricting up and down respectively, at the homonymy of the length direction of spool up and down, respectively supporting be equipped with parallel with spool up and down on, lower guide roll, the two ends that are printed on the door curtain made of cloth of several advertisement pictures are wound in the opposite direction, on the lower winding shaft, on it is walked around lower guide roll between the topped front in stand of part; Be installed on the rope winding up roller of the windlass that has two rope windings up roller below the frame traction rope that twines in the other direction with positive is arranged, one end of rope is fixed on each self-corresponding rope winding up roller, the other end is through being contained in the guiding fixed pulley in the stand, be wrapped in respectively on the winding up roller of rope up and down of upper and lower spool end, end is fixed on its respective rollers, and the coiling direction of the door curtain made of cloth is opposing on traction rope winding direction and each the self-corresponding spool; Between two fixed pulleys of installing relatively on the following traction rope, be equipped with the auto-tensioning wheel.

During work, start windlass, on it two rope winding up roller rotates in the same way and since up and down the traction rope winding direction with separately accordingly the door curtain made of cloth around to opposite, when overhanging cable is tightened up, the door curtain made of cloth is twisted on the upper winding shaft gradually, advertisement picture scrolls up, and following traction rope loosens, and lower winding shaft discharges the door curtain made of cloth, this moment, stretching pulley made traction rope tensioning down drive the lower winding shaft rotation under action of gravity, and the sagging door curtain made of cloth is twisted on the lower winding shaft again; The motor counter-rotating, when traction rope is tightened up instantly, the door curtain made of cloth is shifted to lower winding shaft again, and advertisement picture rolls downwards, and overhanging cable loosens, when the door curtain made of cloth is loose because of conducting oneself with dignity, under the action of gravity of stretching pulley, will descend winding up roller to pull in the other direction and change, the sagging door curtain made of cloth is twisted on the lower winding shaft again, move in circles like this, make that advertisement picture is staggered up and down to roll and can not produce the sagging folded bandwagon effect that influences because of deadweight because of the large-scale door curtain made of cloth that is printed on multi-picture.
