Problems solved by technology
[0005] However, in practical applications, especially in large-scale office environments, due to the frequent use of the protector, user misuse often occurs.
The result of misoperation is that the protective film is not heated enough to completely protect the sheet; or the protective film is overheated, causing the film to stick to the hot pressing roller, resulting in damage to the protective machine and damage to the protective film , the embarrassment that the file after file protection cannot be read
Among them, the misoperation of overheating will mostly cause irreparable damage, and in serious cases, it will even damage the files that were originally intended to be protected.

Embodiment Construction
[0049] Please also refer to figure 1 and figure 2 , figure 1 It shows a back oblique view of a shell protector according to an embodiment of the present invention, figure 2 draw figure 1 Sectional view of the shell protector. The shell protection machine 1 includes a shell 2 , and the shell 2 has a flat base 3 , a front side wall 4 , a rear side wall 5 and an arc upper cover 6 . The arc upper cover 6 connects the front side wall 4 and the rear side wall 5 . The arc loam cake 6 has a plurality of cooling grooves 7, for example with figure 1 configured in the manner shown in .
[0050] A downwardly inclined channel 8 extends through the housing 2 from the rear side wall 5 towards the front side wall 4, and the channel 8 has a width such that a sheet (such as paper) of the German Standardization Institute (Deutsches Institut für Normierung, DIN) A4 standard Channel 8 can be traversed laterally. The channel 8 is defined by a feed opening 9 on the rear side wall 5 and a d...

The invention relates to a shell protection film, a shell protection film group, a method for hot-pressing composite sheets using the same, and a shell protection machine and system using the method. At least one side of the protective film has an initial roughness that makes the protective film matte. The scallop film has a mark, is configured in a surface pattern, and includes a surface part. The surface part is on the matte side and has a different roughness than the starting roughness. The protective membrane set includes a plurality of protective membranes. The method of heat-pressing a composite sheet uses the cladding film. The cladding machine uses the cladding film. The shell protection system includes the shell protection machine and the shell protection film.
Description
technical field [0001] The invention relates to a method for hot-pressing composite sheets, a shell protection film and a shell protection film group applied to the method, and a shell protection machine and a shell protection system using the method. Background technique [0002] In order to protect a sheet (such as an important document), a known method is to heat-compress a protective film and a sheet to be protected (ie, protect the sheet). This action does not need to be carried out in an industrial environment, that is to say, the user can use the shell protection machine (especially in the form of a general table tool) to complete the shell protection action in the office or personal space. This type of shell protection machine is well known (such as the shell protection machine disclosed in German Patent DE 202005005020U1), and some shell protection machines available on the market also integrate a cutting tool (such as the one disclosed in European Patent EP 1724111...
