Description

Technical Field

[0001] This utility model relates to the technical field of adhesive tape production and testing equipment, specifically to an adhesive force testing device for adhesive tape production. Background Technology

[0002] Adhesive tape is a common stationery and packaging material, usually made of plastic film or paper coated with adhesive. It has adhesive properties and can be pasted on various surfaces for fixing, protecting, sealing or marking items. Therefore, the production of adhesive tape needs to ensure its viscosity, which requires the use of an adhesive tape viscosity testing device.

[0003] Existing adhesive strength testing devices for tape production lack temperature control mechanisms. For example, CN201810506878.0 discloses a tape viscosity testing device for tape production. These existing devices lack temperature control for the tested area. Some adhesives used on the tape surface undergo phase transitions at specific temperatures, leading to abrupt changes in adhesive strength. When the tape is being tested, instability in the temperature of either the component used for viscosity testing or the testing stage supporting the tape itself affects the adhesive strength test results. Increased temperature accelerates molecular motion, reducing viscosity and softening the adhesive, while decreased temperature inhibits molecular motion, increasing brittleness and hardening the adhesive. Furthermore, varying ambient temperature affects the tape's adhesion, failing to achieve effective temperature control to improve the efficiency of tape adhesive strength testing.

[0004] Therefore, it is necessary to invent an adhesive force testing device for tape production to solve the above problems. Utility Model Content

[0028] The force gauge 7, heating wire 902, and temperature controller 903 in this device are all existing technologies and will not be described in detail here.

[0029] The working principle of this practical application is as follows:

[0030] Refer to the instruction manual appendix Figure 1-5For this type of adhesive tape production adhesive force testing device, first ensure that all components of the testing device are correctly installed and in good working order. Wrap the tape to be tested around the tape wrapping plate 901, ensuring the tape is flat and tightly adhered. Adjust the temperature controller 903 to set the required test temperature, and start the heating wire 902 for preheating to simulate adhesive force testing under different temperature conditions. Connect the test plate 702 to the first connecting body 701 of the tensile tester 7 via the second connecting body 703 and the threaded post 705. Use the pin 707 to pass through the locking hole 706 to firmly fix the test plate 702 to the tensile tester. Below 7, clamp the two ends of the test stage 9 between the clamping plates 801 and use the fixing bolts 802 to tighten the clamping plates 801 to ensure that the test stage 9 is stable and stationary. Start the servo motor to drive the ball screw 301 to rotate, which in turn drives the screw sleeve 3 to move horizontally along the guide rod 6. The movement of the screw sleeve 3 will pull the tension gauge 7, thereby applying tension to the tape under test. Observe and record the reading of the tension gauge 7, as well as the time or displacement of the tape from the test plate 702, to evaluate the adhesive force of the tape. After the test is completed, collect and record all relevant data, and perform statistical analysis on the data to evaluate whether the adhesive force performance of the tape meets the expected standard.

[0031] The ball screw 301 is driven to rotate by a servo motor, which enables the threaded sleeve 3 to move horizontally on the guide rod 6. The movement of the threaded sleeve 3 causes the tension gauge 7 to apply tension to the tape under test. The tension gauge 7 measures and records the tension value in real time. The heating wire 902 works under the control of the temperature controller 903 to provide the required test temperature for the tape winding plate 901. By simulating the adhesive force test under different temperature environments, the performance of the tape under different temperature conditions can be evaluated. Based on the reading of the tension gauge 7 and the time or displacement of the tape from the test plate 702, the adhesive force of the tape can be evaluated. The greater the adhesive force, the less likely the tape is to fall off when subjected to external force, thus having a better bonding effect and service life. This adhesive force testing device for tape production can accurately evaluate the adhesive force performance of the tape by simulating the tensile force in actual use scenarios and combining it with temperature control function.
