Description

Technical Field

[0001] This utility model relates to the field of whiteboard paper adhesion strength testing technology, and specifically discloses a double-roller peeling device for whiteboard paper adhesion strength testing. Background Technology

[0002] Whiteboard paper is a type of paperboard made of multiple layers of pulp, coatings, or composite materials bonded together. It is widely used in packaging boxes, book covers, and other applications. The interlayer bonding strength directly affects the product's compression resistance, moisture resistance, and service life. Because whiteboard paper is prone to delamination and warping during production or use, it is necessary to quantify the peel force value through adhesive testing to evaluate adhesive performance, optimize process parameters, and ensure compliance with industry standards, thereby avoiding product quality defects caused by adhesive failure.

[0003] Traditional testing methods have significant limitations: manual peeling relies on subjective judgment, resulting in unreliable data; single-roller peeling devices have inconsistent peeling angles, poor adaptability, and lack high-precision force measurement. Utility Model Content

[0004] This invention proposes a double-roller peeling device for testing the adhesion strength of whiteboard paper. By using the synchronous reverse rotation of the two rollers and the direct detection of the embedded tensile sensor, the peeling force value can be measured with high precision. Compared with the traditional manual peeling that relies on subjective judgment, the test is more accurate and has a high degree of automation.

[0005] This utility model is implemented as follows: a double-roller peeling device for testing the adhesion strength of whiteboard paper, comprising:

[0006] Base plate;

[0007] A roller frame symmetrically fixed to the base plate, with two horizontally mounted rotating shafts rotatably connected to the inner side of the roller frame;

[0008] The upper and lower peeling rollers are arranged in parallel, and the upper and lower peeling rollers are respectively fixedly connected to the outer walls of two rotating shafts;

[0009] The drive mechanism includes a motor, a reducer, and a gear set. The output shaft of the motor is fixedly connected to a rotating shaft connected to the upper peeling roller after passing through the reducer. The upper peeling roller and the lower peeling roller rotate synchronously in opposite directions through the gear set.

[0010] The fixing mechanism has two parts, which are respectively installed on the outer walls of the upper and lower peeling rollers. The fixing mechanism includes mounting grooves formed on the outer walls of the upper and lower peeling rollers. A tension sensor is provided on the inner side of the mounting groove, and a strong clamp is fixedly connected to the detection end of the tension sensor.

[0011] As a preferred embodiment of the double-roller peeling device for testing the adhesion strength of whiteboard paper according to this utility model, both the upper peeling roller and the lower peeling roller are fixedly connected to two limiting rings on their outer walls.

[0012] As a preferred embodiment of the double-roller peeling device for testing the adhesion strength of whiteboard paper according to this utility model, the gear set includes two meshing gears, and the two gears are respectively fixed to the outer walls of two rotating shafts.

[0013] In a preferred embodiment of the double-roller peeling device for testing the adhesion strength of whiteboard paper according to this utility model, the motor is a servo motor and the tension sensor is a strain gauge sensor.

[0014] In a preferred embodiment of the double-roller peeling device for testing the adhesion strength of whiteboard paper according to this utility model, the motor is electrically connected to an external control system, and the tension sensor is connected to the external control system via a built-in wireless transmission module.

[0015] As a preferred embodiment of the double-roller peeling device for testing the adhesion strength of whiteboard paper according to this utility model, both the outer walls of the upper peeling roller and the lower peeling roller are coated with an anti-slip coating.

[0016] The beneficial effects of this utility model are:

[0017] This device achieves high-precision measurement of peel force through the synchronous reverse rotation of dual rollers and direct detection by embedded tension sensors. The force is then transmitted wirelessly to an external control system to calculate the adhesion strength of the whiteboard paper. Compared with traditional manual peeling, which relies on subjective judgment, this device provides more accurate testing and a higher degree of automation. It solves the problems of strong subjectivity and high equipment cost of traditional methods and is suitable for rapid quality inspection in the packaging and printing industries.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-3 A two-roller peeling device for testing the adhesion strength of whiteboard paper, comprising:

[0025] Base plate 1;

[0026] The roller frame 2 is symmetrically fixed on the base plate 1, and the inner side of the roller frame 2 is rotatably connected to two horizontally installed rotating shafts 3;

[0027] The upper peeling roller 4 and the lower peeling roller 5 are arranged in parallel, and the upper peeling roller 4 and the lower peeling roller 5 are respectively fixedly connected to the outer wall of the two rotating shafts 3;

[0028] The drive mechanism includes a motor 11, a reducer and a gear set. The output shaft of the motor 11 is fixedly connected to the rotating shaft 3 connected to the upper peeling roller 4 after passing through the reducer. The upper peeling roller 4 and the lower peeling roller 5 rotate synchronously in opposite directions through the gear set.

[0029] The fixing mechanism has two parts, which are respectively installed on the outer walls of the upper peeling roller 4 and the lower peeling roller 5. The fixing mechanism includes a mounting groove 7 opened on the outer wall of the upper peeling roller 4 and the lower peeling roller 5. A tension sensor 8 is provided on the inner side of the mounting groove 7. A strong clamp 9 is fixedly connected to the detection end of the tension sensor 8.

[0030] In this embodiment: the servo motor 11 drives the upper peeling roller 4 to rotate clockwise through the reducer, and at the same time drives the lower peeling roller 5 to rotate counterclockwise synchronously through the meshing transmission of the gear set;

[0031] The two ends of the whiteboard paper sample are fixed to the surface of the two rollers by strong clamps 9. As the rollers move in the opposite direction, they are continuously pulled, which forces the adhesive layers to peel off. The sample is easy to fix and effectively improves the detection efficiency.

[0032] During the peeling process, the tension sensor 8 integrated in the mounting slot 7 detects the normal tension in real time, and the data is sent to the external control system through the wireless transmission module to calculate the adhesion of the whiteboard paper. Compared with the traditional manual peeling that relies on subjective judgment, the test is more accurate and has a high degree of automation.

[0033] The gear set ensures that the speed of the two rollers is strictly synchronized with the transmission ratio of 1:1, and the peeling angle is constant, avoiding test errors caused by speed fluctuations;

[0034] The anti-slip coating increases the friction of the roller surface to prevent the sample from slipping, and the limiting ring 6 constrains the lateral displacement of the sample to ensure uniform force distribution.

[0035] As a technical optimization of this utility model, two limiting rings 6 are fixedly connected to the outer walls of both the upper peeling roller 4 and the lower peeling roller 5.

[0036] In this embodiment, two limiting rings 6 are fixedly connected to the outer walls of both the upper peeling roller 4 and the lower peeling roller 5. The limiting rings 6 constrain the lateral displacement of the sample to ensure uniform force distribution.

[0037] As a technical optimization of this utility model, the gear set includes two meshing gears 10, which are respectively fixed to the outer walls of two rotating shafts 3.

[0038] In this embodiment: the servo motor 11 drives the upper peeling roller 4 to rotate clockwise through the reducer, and at the same time drives the lower peeling roller 5 to rotate counterclockwise synchronously through the meshing transmission of the gear set.

[0039] As a technical optimization of this utility model, motor 11 is a servo motor and tension sensor 8 is a strain sensor.

[0040] In this embodiment: motor 11 is a servo motor, and tension sensor 8 is a strain gauge sensor. The servo motor achieves precise speed adjustment through closed-loop control, and the strain gauge sensor directly detects tension based on the relationship between metal elastic deformation and resistance change.

[0041] As a technical optimization of this utility model, the motor 11 is electrically connected to the external control system, and the tension sensor 8 is connected to the external control system signal through the built-in wireless transmission module.

[0042] In this embodiment: the external control system sets the rotation speed and start / stop commands, and the wireless transmission of sensor data overcomes the wiring limitations of the rotating components.

[0043] As a technical optimization of this utility model, the outer walls of both the upper peeling roller 4 and the lower peeling roller 5 are coated with an anti-slip coating.

[0044] In this embodiment, the anti-slip coating prevents the sample from sliding relative to the roller surface by increasing the coefficient of friction.

[0045] The working principle and usage process of this utility model are as follows: When in use, the whiteboard paper sample is cut into strips (the width of the strips is slightly smaller than the distance between the two limiting rings). Separation openings are pre-cut along the adhesive layer to be tested. Then, the whiteboard paper sample is passed between the upper peeling roller 4 and the lower peeling roller 5, and the separated ends are fixed in the mounting grooves 7 inside the upper peeling roller 4 and the lower peeling roller 5, respectively. Specifically, the two ends of the sample are clamped on two strong clamps 9. The servo motor 11 drives the upper peeling roller 4 to rotate clockwise through the reducer. At the same time, through the gear set meshing transmission, it drives the lower peeling roller 5 to rotate counterclockwise synchronously. The sample is continuously pulled as the roller moves in the opposite direction, forcing the adhesive layers to peel off. During the peeling process, the tension sensor 8 integrated in the mounting groove 7 detects the normal tension in real time. The data is sent to the external control system through the wireless transmission module to calculate the adhesion firmness of the whiteboard paper.
