[0020] The following combines the attached Figures 1-7 , and further illustrates the technical solution of the present invention through specific implementation manners

[0021] The present invention provides an adhesive peeling strength detection device, which includes a test rotating disc 101. Three sliding grooves 104 are formed on the test rotating disc 101. A floating calibration plate 105 is slidably installed in the sliding groove 104. The side surface of the floating calibration plate 105 is perpendicularly arranged with the upper surface of the test rotating disc 101. At positions corresponding to the three sliding grooves 104 on the lower surface of the test rotating disc 101, adjusting screw rods 102 are rotatably installed along the radial direction of the test rotating disc 101. The adjusting screw rods 102 are in threaded driving cooperation with the floating calibration plate 105. A force-receiving test plate 106 is also slidably arranged in the sliding groove 104. A counterweight column storage shell 107 is fixedly installed on the side surface of the force-receiving test plate 106 through a bolt 108. A plurality of counterweight columns 130 can be inserted into the counterweight column storage shell 107. A rotating hollow shaft 110 is fixed at the central position of the lower surface of the test rotating disc 101. An adjusting gear ring 109 is rotatably installed on the circumferential surface of the rotating hollow shaft 110. Adjusting gears 103 are fixed at the opposite ends of the three adjusting screw rods 102. All the adjusting gears 103 are meshed with the adjusting gear ring 109. An aluminum plate ring 124 is fixedly sleeved on the edge of the test rotating disc 101. Monitoring parts are symmetrically arranged on both sides of the aluminum plate ring 124. The monitoring parts include two permanent magnet columns 129 respectively arranged on the upper and lower surfaces of the aluminum plate ring 124. A gap is left between the permanent magnet columns 129 and the aluminum plate ring 124. The two permanent magnet columns 129 are fixed on a permanent magnet column bracket 131. The permanent magnet column bracket 131 is slidably arranged on two arc-shaped sliding rods 126. The two arc-shaped sliding rods 126 are fixed on an outer ring fixed ring 119 through two arc-shaped sliding rod brackets 125. On one side of the two arc-shaped sliding rod brackets 125 facing the permanent magnet column bracket 131, abutment frames 127 are fixed. Force-sensitive resistors 128 are lapped on the opposite surfaces of the two abutment frames 127 and the permanent magnet column bracket 131. A top planetary gear plate 111 is fixed at the bottom end of the rotating hollow shaft 110. A bottom planetary gear plate 112 is fixed on the top planetary gear plate 111. Three planetary gears 113 are rotatably installed between the opposite surfaces of the top planetary gear plate 111 and the bottom planetary gear plate 112. A speed-regulating central gear 114 is meshed at the rotation centers of the three planetary gears 113. The speed-regulating central gear 114 is fixed on the output shaft of a driving motor 122. The output shaft of the driving motor 122 is in rotational cooperation with the rotating hollow shaft 110. The output shaft of the driving motor 122 and the rotating hollow shaft 110 can only rotate circumferentially and cannot displace axially relative to each other. A speed-regulating gear ring bracket 118 is fixedly installed on the outer ring fixed ring 119. A speed-regulating gear ring 115 is rotatably installed on the speed-regulating gear ring bracket 118. The speed-regulating gear ring 115 is in meshing transmission with the three planetary gears 113. Two symmetrically arranged adjusting limit frame guide rods 117 are also fixed on the speed-regulating gear ring bracket 118. An adjusting limit frame 116 is slidably installed on the two adjusting limit frame guide rods 117. Tooth shapes or concave-convex patterns that can be meshed with each other are arranged on the opposite surfaces of the adjusting limit frame 116 and the adjusting gear ring 109.An electromagnet magnetically coupled with the adjusting gear ring 109 is embedded inside the adjusting restraint frame 116. The adjusting gear ring 109 and the rotating hollow shaft 110 can only rotate circumferentially and cannot displace axially relative to each other. The driving motor 122 is fixed to the bottom inside the protective housing 132. A speed regulating motor 123 is also fixed to the bottom inside the protective housing 132. A driving pulley 120 is fixedly installed on the output shaft of the speed regulating motor 123. The driving pulley 120 and the speed regulating gear ring 115 are connected by a transmission belt 121 for transmission.

[0022] The working principle of an adhesive peeling strength testing device disclosed in the present invention is as follows: The fabric to be tested for adhesiveness is adhered to the opposite surfaces of the floating calibration plate 105 and the force-receiving test plate 106. One piece is adhered to each of the floating calibration plate 105 and the force-receiving test plate 106 and waits for drying (the floating calibration plate 105 and the force-receiving test plate 106 are disposable tools. The surfaces of the floating calibration plate 105 and the force-receiving test plate 106 are provided with frosted patterns to increase the adhesion of the glue. This glue is not the adhesive whose adhesiveness is to be tested, and other methods can also be used to fix the fabric to be tested on the floating calibration plate 105 and the force-receiving test plate 106).

[0023] Apply the adhesive with the viscosity to be tested between two pieces of fabric. Select an appropriate number of counterweight posts 130 and insert them into the counterweight post storage shell 107 to serve as counterweights. Then start the drive motor 122 and the speed control motor 123. The output shaft of the drive motor 122 will drive the speed control center gear 114 to rotate. The rotation of the speed control center gear 114 will drive the planetary gear 113 to rotate on its own axis. When the speed control gear ring 115 is under stress, the planetary gear 113 will also revolve. The revolution of the planetary gear 113 will drive the top planetary carrier plate 111 and the bottom planetary carrier plate 112 to rotate. The top planetary carrier plate 111 drives the rotating hollow shaft 110 to rotate, and the rotating hollow shaft 110 drives the test rotating disk 101 to rotate. The rotation of the test rotating disk 101 will drive the counterweight post storage shell 107 to rotate. The rotation of the counterweight post storage shell 107 will move outward along the radial direction of the test rotating disk 101 under the action of centrifugal force (movement tendency). The counterweight post storage shell 107 is fixed to the force test plate 106 by bolts 108. Therefore, there will be a force dragging the force test plate 106 to overcome the adhesive and move away from the floating calibration plate 105. On the premise that the rotation speed of the test rotating disk 101 remains unchanged, changing the number (weight) of the counterweight posts 130 on the counterweight post storage shell 107 can change the force condition of the adhesive, so as to test the viscosity of the adhesive. When the force test plate 106 is under stress, it will overcome the viscosity of the adhesive and move away from the floating calibration plate 105. The greater the distance of this movement, the worse the viscosity of the adhesive is proved. By measuring the capacitance value between the floating calibration plate 105 and the force test plate 106, the distance between the floating calibration plate 105 and the force test plate 106 can be measured, so as to measure the viscosity of the adhesive. In addition to increasing or decreasing the counterweight posts 130 on the counterweight post storage shell 107, the distance between the floating calibration plate 105 and the center of the test rotating disk 101 can also be controlled by rotating the adjustment screw rod 102. Specifically, the electromagnet inside the adjustment limiting frame 116 can be started, and then an attractive force will be generated with the adjustment gear ring 109, so that the adjustment limiting frame 116 moves towards the adjustment gear ring 109. When the adjustment limiting frame 116 contacts the adjustment gear ring 109, the rotation of the adjustment gear ring 109 will be restricted. At this time, since the adjustment screw rod 102 is still revolving, under the restriction of the adjustment gear ring 109, the adjustment screw rod 102 is driven to rotate by the adjustment gear 103, so that the floating calibration plate 105 slides on the sliding groove 104. At this time, since the rotation radius is changed, the force applied to the adhesive to be tested can also be adjusted.

[0024] During the rotation test, the rotation speed of the test rotating disk 101 can be controlled by adjusting the rotation speed and direction of the output shaft of the speed-regulating motor 123. This is because the output shaft of the speed-regulating motor 123 drives the driving pulley 120 to rotate, and the driving pulley 120 drives the speed-regulating gear ring 115 to rotate through the transmission belt 121, thereby changing the force condition on the speed-regulating gear ring 115 (the rotation speed of the speed-regulating gear ring 115 is controlled, and the rotation direction of the test rotating disk 101 needs to be controlled by the driving motor 122).

[0025] To ensure the accuracy of the rotation speed of the test rotating disk 101, an aluminum plate ring 124 is provided on the test rotating disk 101. The rotation of the test rotating disk 101 drives the aluminum plate ring 124 to rotate synchronously. The rotation of the aluminum plate ring 124 cuts the magnetic induction lines between the two permanent magnetic columns 129, thereby generating an induced current in the aluminum plate ring 124. This induced current generates a reverse magnetic field in the aluminum plate ring 124 to hinder the movement of the aluminum plate ring 124. This force is transmitted to the permanent magnetic column 129 through the magnetic force. Since the permanent magnetic column 129 is fixed on the permanent magnetic column bracket 131, and because a force-sensitive resistor 128 is provided between the permanent magnetic column bracket 131 and the abutment 127, the force condition of the permanent magnetic column 129 can be detected through the force-sensitive resistor 128. The magnitude of the force on the permanent magnetic column 129 is related to the rotation speed of the aluminum plate ring 124. The faster the rotation speed of the aluminum plate ring 124, the faster the speed of cutting the magnetic induction lines of the permanent magnetic column 129, and thus the larger the induced current generated, and the larger the magnitude of the force applied to the permanent magnetic column 129. Since two force-sensitive resistors 128 are provided, detection can be performed regardless of whether the test rotating disk 101 rotates clockwise or counterclockwise.
