[0023] In order to make the technical problems, technical schemes and advantages to be solved by the utility model more clear, the following will be described in detail in combination with the drawings and specific embodiments.

[0024] The utility model provides a kind of equipment for detecting the firmness of composite and transfer paper aluminum layer to the existing problem.

[0025] In one embodiment, referring to Figure 1 As shown in the figure, it comprises adhesive tape driving roller 3, combined pressure roller 2, operation control panel 6, base, paper flat table 5 and paper stop rod 4. The adhesive tape driving roller 3 is arranged in cooperation with the combined pressure roller 2. The paper stop rod 4 is arranged on the side of the adhesive tape driving roller 3 and the combined pressure roller 2.

[0026] The adhesive tape driving roller 3 comprises driving motor, lifting adjusting rod 32, driving roller 33 and adhesive layer surface 34. The lifting adjusting rod 32 adjusts the distance between the driving roller 33 and the combined pressure roller 2, the driving motor drives the driving roller 33 to rotate, and the adhesive layer surface 34 is arranged on the outer surface of the driving roller 33.

[0027] The operation control panel 6 is connected with the adhesive tape driving roller 3, and controls the lifting adjusting rod 32 and the driving motor. The operation control panel 6 can control the upward lifting or downward compression test of the adhesive tape driving roller 1, and also can control the running speed of the adhesive tape driving roller 1.

[0028] The paper flat table 5 is arranged on the base, the adhesive tape driving roller 3 is arranged above the base, the combined pressure roller 2 is arranged on the base, and the adhesive tape driving roller 3 and the combined pressure roller 2 are arranged on the two side portions of the paper flat table 5 respectively.

[0029] The adhesive layer surface 34 is provided with reel adhesive tape, the number of the reel adhesive tape is multiple, multiple reel adhesive tapes are arranged in sequence and are wound on the adhesive layer surface 34.

[0030] The base is provided with a support, and the adhesive tape driving roller 3 is arranged on the support.

[0031] The paper 1 before detection is transfer or composite paper with aluminum layer adhered together, and the aluminum layer is upward to detect the firmness of aluminum layer.

[0032] The front side of the adhesive-backed drive roller 3 is a pre-loaded adhesive roller. After each test, the rolled tape can be pulled off to expose the newest adhesive layer 34, allowing for further testing. This pre-loaded adhesive roller is custom-made and has a certain degree of adhesion. The adhesive-backed drive roller 3 is driven by the drive motor. Before testing, the drive roller 33 is raised upwards. During testing, the drive roller 33 rotates via the drive motor and contacts the pressure roller 2 downwards for testing. The rotation speed can be controlled via the operation control panel 6.

[0033] During the test, the adhesive drive roller 3 and the pressing roller 2 press together, and the aluminum layer of the composite paper or transfer paper comes into contact with the adhesive layer 34 of the adhesive drive roller 3. A single sheet of composite paper moves between the adhesive drive roller 3 and the pressing roller 2 in the test.

[0034] With the aluminum side of the sample paper facing upwards, before the adhesive drive roller 3 and the pressing roller 2 are pressed together, pass one end of the test paper through the paper stop rod 4. Start the test and run the adhesive drive roller 3 at a certain speed. After the speed stabilizes, press the sample together. The aluminum side of the paper comes into contact with the adhesive layer 34. Due to the adhesive properties of the adhesive layer 34 and the rotational speed, the test paper will be carried to the other end. This simulates the process of ink contacting paper in a large printing press. Because of the viscosity of the ink, the aluminum layer of the paper comes into contact with the ink, and the ink carries the aluminum layer. This makes the test of the aluminum layer fastness of composite paper more accurate and objective.

[0035] The device for detecting the adhesion of aluminum layers in composite and transferred paper provided by this utility model has the following beneficial effects:

[0036] This device provides a unified, standardized, and regulated operating procedure for testing the reverse tension of the composite aluminum layer. It can accurately control the speed to test the adhesion of ink to the aluminum layer of the composite paper. It can precisely simulate the printing process of paper passing through the ink roller on the printing press, and simulate the adhesion of ink adhesion to the shear angle of the aluminum layer of the paper. The adhesive drive roller 3 can control the speed of the press to simulate the printing speed. This equipment can more realistically and accurately verify the adhesion of the aluminum layer of the composite paper.

[0037] The same sheet of paper can be tested multiple times to simulate the process of paper going through different color groups (e.g., if four colors are printed on the printing press, then the composite paper can be tested four times to verify the strength of the aluminum layer of the composite paper). This test equipment completely ensures that the aluminum layer of the composite paper is not pulled up by the printing ink during the printing process, thus affecting the quality requirements of the printed products.
