[0018] In the description of the utility model, it is necessary to explain that the terms "mounting", "connection" should be understood in a broad sense unless there are explicit provisions and limitations, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium, it can be the communication inside two elements. For the ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0019] A test system for paper composite firmness, as shown in Figure 1 Two groups of rubber roller assemblies 1, a coating machine 2 and a drying box 3, the two groups of rubber roller assemblies 1 are two groups of rubber rollers arranged side by side in front and back and arranged in pairs up and down, the coating machine 2 adopts motor-driven chain transmission, and a limiting switch (not shown in the figure) for limiting the composite length of paper is also installed on the side of the chain of the coating machine 2; the two groups of rubber roller assemblies 1 are installed at the feeding end of the coating machine 2, for the pressure bonding of paper and aluminum film, uniform coating of glue and quantitative control of the amount of glue; the coating machine 2 is placed horizontally at the rear side of the two groups of rubber roller assemblies 1 along the feeding direction of the composite paper, for clamping the composite paper and pulling it through the two groups of rubber roller assemblies 1 at a constant speed; the drying box 3 is a temperature-controllable hot air box, the drying box 3 is provided with heating wires (not shown in the figure), a blower (not shown in the figure), a temperature controller and a sensor for detecting the temperature of the passing composite paper sample, the temperature controller controls the heating power of the heating wires according to the sensor detection data to dry the composite paper sample at a constant temperature, and the drying box 3 is installed on the upper side of the rear end of the coating machine, and the composite paper sample sent by the coating machine at a constant speed is dried at a constant temperature by the heating wires and the blower in the drying box 3.

[0020] Wherein, the upper part of each group of glue roller assembly 1 is provided with a screw adjusting knob (not shown in the figure) for adjusting the gap between the two rollers and a level (not shown in the figure) for ensuring the levelness of the composite roller, the screw adjusting knob effectively adjusts the gap for paper compounding, and is used in cooperation with the level to ensure that the paper loading in the width direction is evenly distributed.

[0021] In this embodiment, the glue cannot be quantitatively controlled, the manual detection has large differences, and the drying is discontinuous during the existing paper compounding firmness test. In particular, when the existing manual compounding firmness test is performed using a measuring rod, the entire width is controlled by manually pressing the measuring rod, and the width of the paper that can be compounded is small, and the loading in the width direction is uneven. The working speed of the existing compounding machine is generally 100-150 m / min. Since the highest coating speed of the coating machine can reach 200 m / min, which is close to the actual compounding condition of the compounding machine, the coating machine is modified to replace part of the function of the compounding machine.

[0022] In this embodiment, at the feeding end of the coating machine 2, glue rollers are arranged in front and back parallel and each group is arranged in pairs. Before each use, the gap between each group of rollers is corrected using a caliper. Before compounding, the aluminum film and the paper are cut according to the standard size, and the glue is manually added to the base paper. The glue layer should be in the form of a line, i.e., there should be no breakpoints, so as to save the amount of glue used and avoid using a glue distributing roller and a loading roller. After the glue is applied, the coating machine 2 clamps the paper and the aluminum film, and pulls them through the two groups of glue rollers at a constant speed. The two groups of glue rollers press the paper and the aluminum film, uniformly apply the glue, and control the amount of glue applied, thereby improving the uniformity of the glue width during the compounding of the paper and the aluminum film. The amount of glue applied is controlled by controlling the gap between each group of glue rollers and the speed of the coating machine 2, thereby realizing automatic control of the compounding of the paper and the aluminum film. A uniform compounding standard and a uniform coating amount are used before the paper compounding firmness test, thereby effectively improving the accuracy of the paper compounding firmness test. Finally, the amount of aluminum points that fall after the paper is compounded is used as a criterion for determining the compounding firmness.

[0023] Meanwhile, the drying box 3 at the rear end of the coating machine 2 is used to dry the tail end using the heating wire and the air blower of the drying box 3, so as to simulate the drying conditions of the paper compounding factory, perform instantaneous drying, dry immediately after compounding, reduce the transition penetration of the glue, realize quantitative glue application before compounding test, and continuously dry, thereby effectively avoiding the differences existing in manual detection.

[0024] The above-described embodiments are only preferred embodiments of the present application, and do not limit the scope of the present application. Any equivalent changes made in accordance with the shape, structure and principle of the present application should be covered within the scope of protection of the present application.
