[0002] The tensile strength of impregnated paper is an important indicator for evaluating its mechanical properties and is usually used for quality control and application suitability evaluation.

[0003] During use, the existing tensile strength testing device for low-formaldehyde furniture impregnated film paper clamps the two ends of the impregnated film paper through clamping mechanisms on both sides, and then uses a tensile testing machine to drive the clamping mechanisms to stretch it. However, there is a probability that the impregnated film paper has local defects, and the length of the impregnated film paper for a single tensile test is relatively long. It is impossible to ensure that the damage caused during the test is caused by defects in the impregnated film paper itself or by overall quality problems of the impregnated film paper.

Detailed implementation manners

[0062] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0063] A tensile strength detection device for low - formaldehyde furniture impregnated film paper disclosed by the present invention is mainly applied to the existing tensile strength detection device for low - formaldehyde furniture impregnated film paper. During use, the two - side clamping mechanisms clamp the two ends of the impregnated film paper, and then the tensile testing machine drives the clamping mechanisms to stretch. However, there is a probability that the impregnated film paper has local defects. The length of the impregnated film paper for a single - stretch detection is relatively large, and it is impossible to ensure whether the damage generated during the detection is caused by the defects of the impregnated film paper itself or by the overall quality problem of the impregnated film paper itself. Therefore, there is a scenario where the detection results are questionable.

[0064] Refer to Figures 1-11 , a tensile strength detection device for low - formaldehyde furniture impregnated film paper, comprising:

[0065] Detection table 1;

[0066] Two adjusting carriages 8, a plurality of adjusting sliding grooves 6 are formed on the detection table 1, and the adjusting carriage 8 is slidably connected to the adjusting sliding groove 6;

[0067] Two fixing plates 9, arranged at the top of the detection table 1 near both sides;

[0068] Two tensile testing machines 5, arranged on the opposite side of the two fixing plates 9;

[0069] Two mounting brackets 7, arranged on both sides of the detection table 1 between the two adjusting carriages 8;

[0078] In a specific application scenario, when detecting the tensile strength of the impregnated film paper, wind it around the two winding rollers 301. During the detection process, one winding roller 301 pays off the line quantitatively, and one winding roller 301 winds up the line quantitatively, so as to quickly perform quantitative length tensile strength detection on the impregnated film paper. Divide a long impregnated film paper into multiple segments for detection, and the detection result of each segment is a set of data, so as to avoid the error caused by the single detection result due to local defects of the impregnated film paper and improve the accuracy of the tensile strength detection result.

[0079] Specifically, after a single wire release is completed, the hydraulic cylinder 316 between the two winding rollers 301 is adjusted to drive the pressure roller 314 to move upward and cooperate with the pressure lever 302. During the movement, the vacuum pump 311 is started, and the impregnated film paper is extruded to the two cooperating pressure levers 302 through the pressure roller 314. The vacuum pump 311 locally adsorbs the impregnated film paper through the adsorption holes 315 on the pressure roller 314, so as to ensure that the impregnated film paper wound on the winding roller 301 will not cause any interference to the impregnated film paper in the detection state during the tensile strength detection, and ensure the accuracy of the detection result.
