Description

Technical Field

[0001] The utility model relates to the technical field of publicity and education, in particular to a publicity device capable of conveniently changing content. Background Art

[0002] Existing propaganda devices often have a simple structure and are often fixed with magnets to solve the problem of inconvenient replacement. For example, the patent number is CN212010260U, named "A kind of ideological and political propaganda device". By installing a silicon steel sheet in the card hole on one side of the display board, the silicon steel sheet is electrified to generate magnetism, so that it generates an adsorption force on the conical block used for fixing, thereby fixing the propaganda paper. However, this method still requires manual adjustment of the position of the fixed paper, which is not only cumbersome to operate, but the fixed paper may still be uneven, resulting in different positions and tightness of the fixed paper each time, which greatly affects the propaganda effect.

[0003] This case was created to solve the above problems. Utility Model Content

[0023] The utility model is further described in detail below through the drawings and embodiments.

[0024] like Figure 1-6 As shown: A promotional device with conveniently replaceable contents comprises a frame 1 and a transparent display board 2 arranged on the frame 1, and a paper feeding port 4 for replacing promotional paper is provided on the upper portion of the display board 2, a limiting track 6 is provided inside the display board 2, and the input end of the limiting track 6 is connected to the paper feeding port 4, a plurality of guiding components 9 are provided at the output end of the limiting track 6, a plurality of parallel and spaced conveyor belts 5 are provided below the guiding components 9, and gaps are left between adjacent conveyor belts 5, and a lower guide groove 71 is provided below the gaps of the conveyor belts 5, which is used to convey and clamp the promotional paper from the gap between the conveyor belts 5 on one side to the gap between the conveyor belts 5 on the other side.

[0025] The receiving assembly 9 includes a support frame 91 located below the limiting track 6, two rotating shafts 92 located in the support frame 91, and a plurality of rollers 93 located on the rotating shafts 92, and the rollers 93 on the two rotating shafts 92 form a channel for the promotional paper to pass through. An opening is provided on one side of the support frame 91, and the size of the opening is larger than the size of the channel formed by the rollers 93 on the two rotating shafts 92.

[0026] The rollers 93 on the two rotating shafts 92 rotate in opposite directions (so that the promotional paper moves downward under the joint action of the rollers 93 on both sides), and the rollers 93 are arranged at an angle to stretch the paper.

[0027] The limiting track 6 is arc-shaped, and the length of the limiting track 6 is adapted to the length of the interior of the display board 2 .

[0028] There are three conveyor belts 5 , and two channels for conveying and clamping promotional papers are formed between the three conveyor belts 5 .

[0029] A cylinder 8 is horizontally arranged above the conveyor belt 5, and an upper guide groove 7 is connected to the output end of the cylinder 8. The upper guide groove 7 is movably connected to the display board 2. The support frame 91 is connected to the other side of the upper guide groove 7 relative to the cylinder 8 and moves with the cylinder 8. A circulating channel is formed among the upper guide groove 7, the conveyor belt 5, and the lower guide groove 71 (so that the promotional paper inside can continuously roll and shift in the circulating channel, thereby meeting the needs of the audience on both sides of the display board 2 for viewing the promotional content).

[0030] The slots of the upper guide slot 7 and the lower guide slot 71 are both provided with guide plates 72, which are arranged obliquely, and the closer to the slot, the closer the guide plates 72 are (similar to the mouth of a collecting funnel, used to ensure that the guided promotional paper does not go astray).

[0031] When in use, the paper to be advertised is inserted into the paper feeding port 4 of the display board 2 (at this time, the cylinder 8 is in a contracted state, such as Figure 4 As shown), due to the existence of the limiting track 6, the paper can only move forward along the track (the track can ensure that the inserted paper is fixed in position, but the track should not be too long, otherwise it is easy to get blocked or stuck). When the paper comes out of the limiting track 6, it is just received by the receiving component 9. At this time, the roller 93 rotates to transport the paper downward (because the roller 93 is tilted toward the outside at a certain angle, the inserted paper tends to move toward the outside on both sides, so that the paper is stretched straight. The inclination angle of the roller should not be too large, generally between 5°-15°). At this time, the conveyor belt 5 is started, so that the promotional paper is clamped by the conveyor belts 5 on both sides and transported downward. When the promotional paper is transported to the bottom of the conveyor belt 5, the promotional paper has been fully unfolded and straightened. At this time, the promotional content can be viewed through the transparent display board 2.

[0032] When the next issue of promotional content needs to be added, or there is more content in the same issue than can be put on one sheet, continue to insert the second sheet of paper into the paper adding port 4 of the display board 2, so that the first sheet of promotional content is output to the lower guide groove 71 by the conveyor belt 5, and then enters between the two conveyor belts 5 on the other side. The conveyor belt 5 continues to convey, so that the first sheet of promotional paper comes to the top of the conveyor belt 5, and the second sheet of promotional paper replaces the original position of the first sheet of promotional paper, so that the promotional device can promote on both sides of the display board 2 at the same time.

[0033] At this time, the cylinder 8 is started to extend, pushing the upper guide groove 7 to above the gap formed by the conveyor belt 5, thereby forming a circulating channel among the upper guide groove 7, the conveyor belt 5, and the lower guide groove 71. When people watch the promotional content in front of the display board 2, the front and rear promotional content can circulate back and forth on the display board 2, thereby greatly improving the promotional effect.

[0034] When the promotion is finished, the cylinder 8 contracts, so that the upper guide groove 7 guides the promotional paper output by the conveyor belt 5 to the outside of the conveyor belt 5 and into the recovery bin 3, so that the staff does not need to personally remove the previous promotional content, thereby completing a more convenient replacement.

[0035] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
