Description

Large-scale combined from moving picture advertisement device

Technical field

The utility model belongs to advertisement machine, and is especially a kind of large-scale combined from moving picture advertisement device.

Background technology

The advertisement machine of moving picture certainly of Chu Shouing in the market, be in window back, advertisement kitchen, 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 several advertisement pictures, the homonymy termination of its diaxon is connected with the belt pulley of band clutch coupling respectively, and links 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, drives one of them spool, and another spool is realized the effect that advertisement picture rolls and shows by door curtain made of cloth traction passive rotation.Because spool with how many its external diameters that lick the door curtain made of cloth is in the variation, when a separated spool of clutch coupling is in the relieving state and is affected, since door curtain made of cloth dead weight particularly large-screen wide to accuse the door curtain made of cloth of machine big, easily cause the folded phenomenon of its sagging generation, can not realize the normal presentation that large-screen wide is accused.

Summary of the invention

Large-scale the picture advertisement device map sheet is big from moving in order to solve, the easy folded problem that influences the advertisement bandwagon effect of door curtain made of cloth during picture rolling, the technical solution of the utility model is: in a rectangular frame of erectting, space in the frame is divided into a plurality of sections, both sides in each section, be supported with two spools that are parallel to each other with bearing respectively, at spool one end, pass with mandrel in the bearing of framework insertion roller tube end installation, be fixed on the framework in its termination, in the bar portion of mandrel, be equipped with compression spring between its pillow block and the spool shaft shoulder; Be fixed with onesize spool belt wheel on the spindle nose of the spool other end respectively, between the bearing seat of the shaft shoulder of taking turns inboard spool and supporting shaft, overrunning clutch is installed, cover is fixed on the spool spindle nose in it, be fixed with wearing piece on the end face of its overcoat and between the bearing seat, the overrunning clutch that is installed on the two spool spindle noses in every section is one positive one anti-opposing direction; Press close to the front on the framework in two spool both sides, at the framework upper support deflector roll parallel with spool arranged respectively with bearing, the door curtain made of cloth two ends that have advertisement picture are wound on two spools in the opposite direction, and are behind each self-corresponding deflector roll of middle pile warp, topped on the front of advertisement machine; In the stull of framework bottom, fixedly be equipped with the motor of same belt leather belt wheel, and be connected with spool belt wheel on two spools respectively by belt.

During use, start the motor in each section of advertisement machine simultaneously and it is rotated in the same way, because the overrunning clutch on the spool in every section is installed in the other direction with one positive one, and there is spring to be pressed on the shaft shoulder of spool, therefore no matter forward or reverse, all there is a spool initiatively, one passive, passive rotation spool also give the axial force of spool and press to wearing piece because of spring, spool is not differed because of door curtain made of cloth degree of tightness appears in the external diameter size variation, make the door curtain made of cloth be in tensioning state all the time and do not produce folded phenomenon; Can be that every section complete picture is many pictures and shows simultaneously on the door curtain made of cloth that multistage moves, also can be that a big picture segmentation is imprinted on each door curtain made of cloth, combines into a large-scale picture exhibition then.This machine is simple in structure, overcome a big door curtain made of cloth conducts oneself with dignity too that Da Yi causes the sagging folded shortcoming of the door curtain made of cloth, and the segmentation combination realizes large-scale from the normal presentation of moving picture advertisement device.
