It should be understood that the present application is not limited to the manner of mounting the upper press roller 2 and the lower press roller 3 rotatably and slidably up and down, and the following only provides a specific structure for reference: as shown in fig. 1 to 3, at least one end of the upper press roller 2 and at least one end of the lower press roller 3 are rotatably provided with a slide block 8, and the slide block 8 is connected to the frame 1 in a vertically sliding manner. The up-and-down sliding of the slide block 8 is equivalent to the up-and-down sliding of the upper press roller 2 or the lower press roller 3; and the upper press roller 2 and the lower press roller can rotate relative to the corresponding sliding blocks 8, which is equivalent to realizing rotatable connection between the upper press roller 2 and the frame 1 and between the lower press roller 3 and the frame 1.

It should be understood that the specific structure of the pressing mechanism 4 is not limited in the present application, and for example, in the case where the slider 8 is provided, the pressing mechanism 4 may be a telescopic member through which the slider 8 is driven to slide up and down. It will be appreciated that the two upper and lower adjacent sliders 8 (i.e., the upper platen roller 2 and the lower platen roller 3) can be slid in opposite directions or slid in opposite directions by driving the upper slider 8 to slide up and down (i.e., applying pressure to the upper slider 8) by the telescopic members, or driving the lower slider 8 to slide up and down (i.e., applying pressure to the lower slider 8) by the telescopic members, or driving the two upper and lower adjacent sliders 8 to slide up and down (i.e., applying pressure to the two upper and lower adjacent sliders 8) by the two telescopic members, respectively. Preferably, the telescopic member drives the upper sliding block 8 to slide up and down, so that the lower sliding block 8 (namely the lower pressing roller 3) can keep the height unchanged, and is convenient to be matched with the supporting plate 7 for use.

It should be noted that the telescopic member itself belongs to the prior art, for example, the telescopic member is a cylinder, a hydraulic cylinder, an electric telescopic rod, and the like. The pressure detection mechanism may be a pressure sensor, and the pressure sensor may be disposed between the expansion member and the slider 8, or may be disposed between two sliders 8 adjacent to each other, and the pressure generated between the upper platen roller 2 and the lower platen roller 3 may be detected by the pressure sensor. When the telescopic part is the cylinder, the pressure detection mechanism can also be a barometer, and the pressure in the cylinder can be detected through the barometer, so that the actual applied pressure of the cylinder can be reflected. Similarly, when the telescopic part is a hydraulic cylinder, the pressure detection mechanism can also be an oil pressure gauge, and the oil pressure in the hydraulic cylinder can be detected through the oil pressure gauge, so that the actual applied pressure of the hydraulic cylinder can be reflected.

It should be understood that the driving mechanism (i.e. the manner of driving the upper press roller 2 and the lower press roller 3 to rotate) is not limited, and for example, the upper press roller 2 or the lower press roller 3 may be directly rotated by hand; or a hand driving piece 5 (shown in fig. 1 and 2) is arranged at the end part of the lower pressing roll 3 (and/or the upper pressing roll 2), and the lower pressing roll 3 is driven to rotate or the upper pressing roll 2 is driven to rotate by the hand driving piece 5; or an automatic driving part is arranged at the end part of the lower press roll 3 (and/or the upper press roll 2), and the upper press roll 2 is driven to rotate or the lower press roll 3 is driven to rotate or the upper press roll 2 and the lower press roll 3 are driven to rotate simultaneously, etc. It should be noted that, the specific structure, the installation manner and the operation control manner of the hand driving member 5 (such as a turntable and a handle) and the automatic driving member (such as a motor) are all the prior art, and are not described in detail in the present application.

Referring to fig. 1 and 3, in some embodiments of the present application, in order to facilitate supporting the sheet 200, the film test apparatus further includes a support plate 7, and at least one of both sides of the lower press roller 3 is provided with the support plate 7. It will be appreciated by those skilled in the art that the side of the upper surface of the support plate 7 adjacent the lower platen roller 3 is maintained flush with the upper side of the lower platen roller 3 or that the side of the upper surface of the support plate 7 adjacent the lower platen roller 3 is slightly lower than the upper side of the lower platen roller 3 to prevent the support plate 7 from interfering with the passage of the sheet 200 between the upper and lower platen rollers 2, 3.

Referring to fig. 1 and 3, in some embodiments of the present application, in order to achieve automatic feeding of the protective film 101, the film laminating test apparatus further includes a film feeding mechanism 6, the film feeding mechanism 6 includes a fixing roller 61 for fixing the film roll 100, one end of the fixing roller 61 is rotatably disposed on the frame 1, and an axis of the fixing roller 61 is parallel to an axis of the upper pressing roller 2. As shown in fig. 3, by fixing the film roll 100 on the fixed roller 61 and pulling the protective film 101 on the film roll 100 between the upper press roller 2 and the lower press roller 3, the protective film 101 can be pressed against the surface of the plate 200 under the mutual pressing action of the upper press roller 2 and the lower press roller 3.

It will be appreciated that when the film roll 100 is positioned above the sheet 200, the protective film 101 is pressed against the upper surface of the sheet 200; when the film roll 100 is located below the plate 200, the protective film 101 is pressed against the lower surface of the plate 200. After the support plate 7 is provided, the protective film 101 is preferably pressed against the upper surface of the plate 200 in order to prevent abrasion between the protective film 101 and the support plate 7.

It should be understood that a driving motor may be further provided on the frame 1, and the fixing roller 61 is driven to rotate by the driving motor, so that the release speed of the protective film 101 can be precisely controlled. Of course, even if a driving motor is not provided, the friction force between the upper press roller 2 and the lower press roller 3 pulls the protective film 101 to release, and does not affect the use.

It should be noted that the mounting manner between the film roll 100 (i.e., the roll core of the film roll 100) and the fixed roll 61 is not limited, but in order to facilitate the disassembly and assembly of the roll core, the fixed roll 61 is preferably an inflatable roll, so that the roll core can be disassembled and assembled quickly to replace the film roll 100 with a new one.

Referring to fig. 1 and 3, in some embodiments of the present application, in order to improve the conveying effect and stability of the protective film 101, the film supply mechanism 6 further includes a guide roller 62 for guiding the protective film 101 on the film roll 100 to pass between the upper pressing roller 2 and the lower pressing roller 3, the guide roller 62 is rotatably provided to the frame 1, and an axis of the guide roller 62 is parallel to an axis of the fixed roller 61.

The foregoing has outlined the basic principles, features, and advantages of the present application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present application, and various changes and modifications may be made therein without departing from the spirit and scope of the application, which is defined by the appended claims.
