[0017] The device for detecting the peeling degree of self-adhesive paper proposed by the present invention can bring the following beneficial effects:

[0018] 1. The peeling degree detection device of the self-adhesive paper cooperates with the fixing mechanism and the pressing mechanism through the force measuring mechanism. After the self-adhesive paper is fixed, the fixing mechanism connected to the force measuring mechanism is suspended in the air to ensure that the digital push-pull force gauge in the force measuring mechanism measures the force generated by the self-weight of the fixing mechanism. After it is set to zero, the self-adhesive paper can be tested to ensure that the force measuring mechanism accurately measures the force required to peel off the self-adhesive paper, avoiding the automatic influence of the fixing mechanism on the test results. The fixing mechanism can fix the peeling part of the self-adhesive paper as a whole to avoid the problem of tearing of the bottom paper during the peeling process, avoiding waste of resources and ensuring the accuracy of the test results. When the peeling degree detection device is used to detect the self-adhesive paper, the fixing parts in the detection device are used to fix the bottom paper, but the weight of the fixing parts themselves will cause deviations in the test results. At the same time, if the bottom paper is partially fixed, it is easy to cause the bottom paper to tear during the pulling process, which will not only waste resources but also cause inaccurate test results.

[0019] 2. The peeling degree detection device of the self-adhesive paper cooperates with the placing mechanism and the pressing mechanism. In the placing mechanism, the exhaust fan works through the exhaust hood through the exhaust pipe, thereby generating negative pressure on the surface of the perforated plate to ensure that the surface paper is tightly attached to the surface of the perforated plate. At this time, the two pressing cross bars in the pressing mechanism press the two sides of the self-adhesive paper and reserve the torn bottom paper. The personnel can tear off the bottom paper on both sides of the self-adhesive paper along the pressing cross bars to ensure that the remaining part of the bottom paper is in a regular shape and that the bonding parts of the bottom paper and the face paper are evenly stressed. At this time, the two pressing cross bars press on the torn part of the bottom paper to ensure that the self-adhesive paper is fixed and stable, and cooperate with the fixing mechanism to completely clamp one end of the bottom paper to ensure stability during the detection process.

[0020] 3. The peeling degree detection device of the self-adhesive paper cooperates with the fixing mechanism through the force measuring mechanism. The L-shaped jacket connected to the guide column clamps the digital push-pull force gauge. The compression spring on the guide column ensures that the L-shaped jacket fixes the digital push-pull force gauge. The force measuring screw connected to the digital push-pull force gauge is connected to the screw joint in the fixing mechanism, which is convenient for personnel to disassemble the digital push-pull force gauge. The fixing mechanism is easy to disassemble, which is convenient for personnel to inspect and maintain the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Working principle: When using the peeling degree detection device, the personnel selects the self-adhesive paper with regular shape and places the self-adhesive paper at the center of the placement mechanism 6. At this time, the exhaust fan 604 works to extract the air in the exhaust hood 601 through the exhaust pipe 603, so that the surface of the perforated plate 602 generates negative pressure, which can make the self-adhesive paper stick to the surface of the perforated plate 602. At this time, in the pressing mechanism 7, the second stepping motor 705 rotates forward to drive the first bevel gear 706, and the first bevel gear 706 acts on the second bevel gear 707, so that the bidirectional lead screw 702 drives the two movable blocks 703 to approach, and the horizontal bar 704 moves to the horizontal position. After moving to the top of the self-adhesive paper and leaving a tearing position, the pressing screw 708 is driven by the turntable to make the pressing cross bar 709 press on both sides of the self-adhesive paper. At this time, the personnel tear off the reserved bottom paper on both sides along the pressing cross bar 709, rotate the pressing screw 708 to raise the pressing cross bar 709, and the second stepper motor 705 reverses to make the two movable blocks 703 move away. The pressing cross bar 709 moves to the tearing position of the bottom paper of the self-adhesive paper, and the pressing screw 708 is rotated to make the pressing cross bar 709 press on both sides of the self-adhesive paper to ensure that it is fixed firmly and that the remaining bottom paper has a regular shape after the bottom paper is partially torn off.

[0039] At this time, in the transverse movement mechanism 2, the first stepper motor 203 drives the driving screw 202, and the two driving sprockets 204 are transmitted through the transmission chain 205. The driving screw 202 can drive the lifting mechanism 3 on the transverse movement block to move above the self-adhesive paper. The electric cylinder 302 on the support frame 301 in the lifting mechanism 3 is connected to the U-shaped movable frame 303 to ensure that the fixing mechanism 5 connected to the force measuring mechanism 4 is suspended in the air. The L-shaped jacket 406 connected to the guide column 404 in the force measuring mechanism 4 ensures the fixation of the digital push-pull force gauge 408 under the action of the clamping spring 407. The L-shaped pressure plate 409 and the clamping knob 410 cooperate to fix it. At this time, turn on the digital push-pull force gauge 408. When the value displayed is zero, connect the force measuring screw 411 of the digital push-pull force gauge 408 to the screw joint 503 in the fixing mechanism 5. At this time, the pulling force generated by the deadweight of the fixing mechanism 5 is clamped by the digital push-pull force gauge. 408, the personnel can record and then set the value to zero. The personnel will uncover the end of the bottom paper of the self-adhesive paper, and move the fixing mechanism 5 downward with the cooperation of the lifting mechanism 3 to ensure that the fixing mechanism 5 is always in a suspended state. In the fixing mechanism 5, the personnel rotates the second clamping plate 504 hinged to the first clamping plate 501, and places the end of the bottom paper between the first clamping plate 501 and the second clamping plate 504, and then rotates the tightening knob 508 on the L-shaped bracket 507 to act on the second clamping plate 504, and the anti-slip plate 505 cooperates with the anti-slip strip 506 to ensure that the end of the bottom paper is fixed as a whole. Then the lifting mechanism 3 raises the force measuring mechanism 4 and the fixed mechanism 5 connected thereto, and at the same time the transverse movement mechanism 2 ensures that the lifting mechanism 3 moves transversely, thereby separating the bottom paper and the face paper of the self-adhesive paper. During the separation process, the value displayed by the digital push-pull force gauge 408 is the force required to uncover the self-adhesive paper.
