Abstract

The utility model relates to an automatic changing advertisement machine with multiple pictures, which belongs to advertisement equipment. The utility model is mainly characterized in that one end of a frame composed of multiple pictures is fixed and wound on a reel shaft, and the other end winds around a guide shaft to be fixed and wound on the other reel shaft; the two reel shafts are respectively connected with a driving motor via the drive of belts; the tensioning degree of the two belts are controlled by an eccentric wheel driven by an inverting motor. Therefore, the separation and the binding of the two reel shafts and the motive force of the driving motor can be realized. The driving motor and the inverting motor pause in definite time or rotate continuously under the control of a common controlling circuit to make the multiple pictures transformed circularly. The advertisement light box has the advantages of high information capacity, flat picture and simple structure and is suitable for making advertisents in plates, such as roadsides, building roofs, bus stops, playgrounds, hotels, emporiums, etc. The automatic changing advertisement machine with multiple pictures can also be used for ornamental projects.

Description

Many pictures are changed advertisement machine automatically

The utility model relates to a kind of advertising apparatus, i.e. advertisement machine.

Up to now, advertising apparatus that can the conversion picture has following several: a kind of is electronic display, it utilizes the various combination of electronic light-emitting component to come the conversion display message, its cost of manufacture height, electronic light-emitting component is fragile, and color and sharpness are also because of being subjected to material and making poor effect that principle is limit; A kind of is three surface overturning billboards, and it is rearranged by a plurality of triangular prisms, forms three width of cloth pictures by the upset of triangular prism, its defective is that picture mostly is three width of cloth most, and picture is imperfect, unsuitable interior polishing, display effect is poor, and is fragile under wind action during outdoor installation; Also having a kind of is as shown in Chinese patent 94244688.7 and 96248758.9, at casing four jiaos an axle is installed respectively, wherein two is to reel the spool of picture, realizes that by alternately reeling of diaxon picture changes, but all do not solve picture tensioning and commutation problem not perfectly, the actual effect picture is loose, and it is irregular to reel, and it is unreliable to commutate, display effect is poor, complex structure, the failure rate height, actual use value is low.In view of above reason, at present most widely used is the advertising lamp box that has only a width of cloth fixed image, and this advertising apparatus information capacity is little, does not have innervation, and effect is bad.

The purpose of this utility model just is at above-mentioned weak point, existing advertising apparatus is improved, a kind of conversion multi-picture automatically is provided, the easy tensioning of picture, not lax, show smooth, effective, the power clutch did not have impact, noiselessness when diaxon was alternately reeled, commutation is reliable, advertising apparatus simple in structure, and promptly many pictures are changed advertisement machine automatically.

For achieving the above object, the technical solution adopted in the utility model is: be provided with two with spool and the some axis of guides at box house, one end of the picture of being made up of multi-picture is fixed and is wound on the spool, and the other end is walked around the axis of guide and fixed and be wound on another spool; Two spools link with drive motor respectively by belt gear, two belts are controlled its tensioning degree by the eccentric wheel that reversing motor drove, the nothing that had so both realized two spools and drive motor power is impacted and is separated and engage, and can control the tensioning degree of picture again by the tightness that eccentric wheel is controlled driven spool and belt; Regularly intermittently or continuously rotate with a control circuit controlling and driving motor and reversing motor then, make the multi-picture cyclic transformation.

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

Accompanying drawing 1 is the utility model inner structure front schematic view;

Accompanying drawing 2 is the utility model inner structure schematic top plan view;

Among the figure, 1. casing 2. axis of guides 3. spools 4. belt pulleys 5. spools 6. belt pulleys 7. belts 8. belts 9. eccentric wheels 10. reversing motors 11. belt pulleys 12. drive motor 13. belt pulleys 14. drive motor 15. pictures

The utility model partly is made up of casing 1, picture 15, mechanical driving part and control circuit.Mechanical driving part is following setting: four jiaos of places at casing are provided with the axis of guide 2 respectively, side at casing is provided with two spools 3 and 5, at an end of two spools one belt pulley 4 and 6 are installed respectively, link to each other with 13 with belt pulley 11 with 8 by belt 7, belt pulley 11 links to each other with 14 with drive motor 12 respectively again with 13 again; One eccentric wheel 9 is set between two belts, and eccentric wheel 9 links to each other with reversing motor 10.

One end of the picture of being made up of multi-picture 15 is fixed and is wound on the spool 3, and it is fixing and be wound on the spool 5 that the other end is walked around four axis of guides 2.

Control circuit is used for the timing of controlling and driving motor and reversing motor and intermittently or continuously rotates, and is a common existing control circuit, and is not shown.

Compress belt 8 when eccentric wheel 9 is positioned at, when loosening the position of belt 7, spool 5 be spool initiatively under drive motor 14 drives, it is driven spool that spool 3 breaks away from drive motor 12, picture by spool 3 around to spool 5; At this moment, owing to, can make driven spool 3 and belt 7 keep a suitable pressure, thereby make picture guarantee suitable tensioning degree in advance to the adjustment of belt gear centre distance and eccentric wheel eccentric throw.When picture is all emitted from spool 3, control circuit control reversing motor 10 rotates, the position that eccentric wheel is positioned at compress belt 7, loosen belt 8,3 of spools are the active spool under drive motor 12 drives, spool 5 breaks away from drive motor 14 and is driven spool, picture by spool 5 around to spool 3, at this moment, in like manner can make driven spool 5 and belt 8 keep a suitable pressure, make picture guarantee suitable tensioning degree.

The advertising lamp box that utilizes the utility model to provide can reach the purpose that circulation shows multi-picture, has increased information capacity, has strengthened innervation; Main drive gear adopts belt gear and eccentric mechanism, and spool can only be rotated under power drive and the effect of picture pulling force, can not freely rotate, thereby make picture remain tensioning state, and it is neat to reel, and shows smooth, effective; Adopt joint that belt gear and eccentric mechanism realize two spools and power and separate, smooth engagement, do not have impact, noiseless, simple in structure, compact dimensions, an and belt is when compacted, another belt must loosen, commutation accurately, reliable.

Claims

1. picture is changed advertisement machine automatically more than one kind, comprise casing, picture, mechanical driving part and control motor regularly intermittence or the continuous general control circuit that turns round, it is characterized in that: said mechanical driving part is to form like this: be provided with two with spool and the some axis of guides at box house, two spools link with drive motor respectively by belt gear, and two belts are controlled its tensioning degree by the eccentric wheel that reversing motor drove.
