Description

Several faces advertising device of displaying by screens

The utility model belongs to advertisement, is specifically related to a kind of advertising device of variable information.

Chinese patent CN87207983U discloses a kind of swinging advertising device.It comprises the screen-type tank tower that has pedestal, there is the screen window in the tank tower front, stand on the lamp plate of screen window back, be located at the motor of base bottom, be located in the tank tower by electric motor driven connecting gear, be enclosed within the ring-type advertisement belt of making by translucent flexible material on the connecting gear, connecting gear is the driving wheel that is connected by with the motor belt, be located at the dancer rools that is positioned at lamp plate top and lamp plate back in the tank tower, and one group of slewing rollers is formed the travelling belt of ring-type advertisement belt formation gear train itself.This swinging advertising device advertisement capacity is big, can show several advertisement pictures continuously, its shortcoming is not have the time-out of motor and start automaton, cause all advertisement pictures ceaselessly to be displayed by screens continuously, locating and displaying regularly, advertising results are poor, simultaneously because its connecting gear unreasonable structure and arrangement, cause the ring-type advertisement belt that difficulty is installed, loose skidding is arranged during the advertisement belt revolution.

The purpose of this utility model provides that a kind of advertisement capacity is big, and connecting gear is rational in infrastructure, can broadcast by automatic rolling, again several faces of locating and displaying advertising device of displaying by screens regularly.

For achieving the above object, the utility model is achieved in that a kind of several faces advertising device of displaying by screens, it comprises a box frame with screen window, be located at the reinforcement protective shield that stands on screen window back in the box frame, be located to lay respectively in the box frame and strengthen on the protective shield, following back-up roller and hold-down roll, be located at and be positioned at the suspension cylinder group of strengthening the protective shield back in the box frame, be sleeved on back-up roller, ring-type advertisement painting canvas on hold-down roll and the suspension cylinder group, be located at the box frame bottom and be used to drive the disc type electric machine of ring-type advertisement poster cloth rotation and coupled gear train, wherein gear train is the worm type of reduction gearing that is connected by with the disc type electric machine belt, form by the idle pulley of this speed reduction unit drive with the rubber roll of its engagement, rubber roll is close to mutually with hold-down roll, co-extruded rotating band rotating ring shape advertisement painting canvas rotates, and the lateral edges at ring-type advertisement painting canvas is equipped with and each advertisement picture corresponding positioning hole, be provided with the optoelectronic switch in detection and location hole in the side of box frame correspondence, it is connected with a Programmable Logic Controller, Programmable Logic Controller is connected with disc type electric machine by an A.C. contactor, with the rotation and the time-out of control disc type electric machine, realize the timing locating and displaying of advertisement picture.

Compare with existing swinging advertising device, not only the advertisement capacity is big for the utility model, cylinder steering mechanism and gear train are rational in infrastructure, advertisement painting canvas suit is convenient, and slow-roll stabilization is reliable, and because of setting up by optoelectronic switch, the disc type electric machine automaton that Programmable Logic Controller and A.C. contactor are formed, advertisement picture can automatic rolling be broadcasted, locating and displaying regularly again, good advertising effect.

Now in conjunction with the accompanying drawings and embodiments the utility model is done specific descriptions:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is electric control theory figure of the present utility model.

As depicted in figs. 1 and 2, a kind of several faces advertising device of displaying by screens, it comprises a box frame 13, its front has the screen window, but stand on the reinforcement protective shield 3 of the double as lamp plate of screen window back, be respectively equipped with corresponding back-up roller 1 and the hold-down roll of arranging 5 in the above and below of strengthening protective shield 3, be provided with the suspension cylinder group 12 of alternative arrangement up and down in the back of strengthening protective shield 3, the two end supports of each cylinder is on the set bearing in box frame 13 both sides, they can be rotated around each bearing, constitute steering mechanism.Ring-type advertisement painting canvas 2 is sleeved in this steering mechanism, can gyration.Pivoted loop around advertisement painting canvas 2 on store several advertisement pictures.During suit advertisement painting canvas 2, for ease of regulating its tensile force, the two ends that hang the last root cylinder in the cylinder group 12 are unfixing, but be positioned at the set gathering sill in box frame 13 both sides, can move up and down along gathering sill, and lean on its deadweight or add lift heavy with 2 tensionings of advertisement painting canvas, form the tension drum 11 of regulating advertisement painting canvas elasticity.The rubber profile of tooth idle pulley 7 that disc type electric machine 9, the worm type of reduction gearing 8 that is connected with disc type electric machine 9 belts is installed in the bottom of box frame 13, drives by speed reduction unit 8 and with the rubber roll 6 of its engagement, rubber roll 6 is close to mutually with hold-down roll 5.The rotation of motor 9 drives rubber roll 6 by speed reduction unit 8 and idle pulley 7 and rotates, and rubber roll 6 drives advertisement poster cloth 2 with the rotation of hold-down roll 5 co-extruded and rotates, and realizes displaying by screens of advertisement picture.Lateral edges at ring-type advertisement painting canvas 2 is equipped with and each advertisement picture corresponding positioning hole, on the side of box frame 13 correspondences, be provided with the optoelectronic switch 4 in detection and location hole, it is made up of light emitting diode and phototriode, it is connected with Programmable Logic Controller 10 on being located at box frame 13 base plates, and this controller 10 also is connected with disc type electric machine 9 by A.C. contactor.When optoelectronic switch 4 detects pilot hole on the advertisement painting canvas 2, signal is imported Programmable Logic Controller 10 (PLC), Programmable Logic Controller 10 stops output, A.C. contactor (JC ₁) outage, making motor 9 stalls, advertisement painting canvas 2 suspends, and shows its advertisement picture.Programmable Logic Controller 10 can preestablish time out, after reaching time out, connects A.C. contactor again automatically, motor 9 is started, drive advertisement painting canvas 2 and rotate, detect next pilot hole up to optoelectronic switch 4, so circulation, the self-timing locating and displaying of realization advertisement picture
