Disadvantages of water screen movies:
A, the cost is too high. The small vertical water curtain may have the lowest cost, but the imaging range is too small, which is of little significance. The largest, Singaporean, fixed water curtain landscape film is reported to have invested more than 130 million Singapore dollars; the domestically held, medium-sized water curtain landscape, generally invested more than 20 million yuan; large, single, laser effect It is reported that the water curtain performance is also invested more than 10 million yuan. The electricity, water, space, and personnel costs of the water curtain work are like burning money, and the maintenance cost is very high.
B, venue restrictions. It can only be held in outdoor areas that are very open, such as pools, lakes, rivers, rivers, beaches, or squares that provide excellent water supply and drainage systems.

It can be performed all year round. Some weather changes can also have unpredictable effects on water screen movies, such as heavy rain, heavy fog, strong wind, lightning, hail, etc.
D, technical limitations. Many hardware devices need to be imported, and there are many technical restrictions. Take the three-dimensional plane water curtain as an example, the power of the ultra-high pressure water pump is limited, and the height of spraying from the bottom to the top is limited; the screen is huge, and dynamic images such as video are played, which requires high brightness for large-scale engineering projectors; super long and super wide , Splicing and fusion technology, etc.
E, the picture effect is rough. Due to the size, the brightness of the light is not high, and the water medium is not flat, the water curtain generally only looks at the macro scene, and does not demand detailed performance. To put it simply, just see the painting. Don't be picky about color, clarity, and so on.
The banknote bundling machine was developed in response to the lack of currency adjustment, security protection, and fault detection functions of the existing banknote bundling machine, which brought inconvenience to users. It is mainly composed of paper money steering manipulator, currency value adjusting device, mechanical pressing device, sticking and cutting device, cross sticking device, tape transport device, automatic tape take-up mechanism, safety protection, fault alarm device and dust removal device. It can quickly complete the functions of compacting, bundling, turning, sticking and cutting large banknotes. The utility model can be widely used for bundling large amounts of banknotes in the financial and securities industries.
