Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape viscosity testing, in particular to an adhesive tape viscosity testing device. Background Art

[0002] Adhesive tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. A layer of adhesive is coated on its surface. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives. Various polymers are widely used in modern times.

[0003] After production, the adhesive tape needs to be tested for viscosity to determine whether it meets the requirements. However, the tape is difficult to lay flat on the test device during testing, and even after multiple tests, adhesive may remain on the test board. This may affect subsequent tape test results. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a tape viscosity testing device to solve the problem mentioned in the above background technology that the tape viscosity needs to be tested after production is completed to detect whether the viscosity of the tape is qualified. However, the tape is difficult to lay flat on the testing device during the test, and after multiple tests, there may be residual adhesive on the tape on the test board, which may affect the test results of subsequent tapes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tape viscosity testing device, comprising a base plate, four supporting legs fixedly installed on the bottom of the base plate, the four supporting legs are arranged in a rectangular array at the bottom of the base plate, a controller is provided on the upper end surface of the base plate, a detection platform is fixedly installed at a position closer to the middle of the upper surface of the base plate, a mounting plate is fixedly installed at a position closer to the rear end of the upper surface of the base plate, two rotating rollers are rotatably installed on the front end surface of the mounting plate, the two rotating rollers are installed opposite to each other, and two slide grooves are provided on the front end surface of the installation, and the two slide grooves are symmetrically distributed.

[0006] By adopting the above technical solution, the test device is supported by four supporting legs installed at the bottom of the base plate. Then, when the viscosity of the produced tape needs to be tested, the tape to be tested is first placed on the test table, and then the sticky side of the tape is facing up, and then both ends of the tape are wrapped around the rotating roller. Then the staff rotates the rotating roller to keep the tape flat on the test table, thereby improving the test effect.

[0007] Preferably, two drive motors distributed in opposite directions are fixedly mounted on the mounting plate, and threaded rods are fixedly mounted on the output ends of the two drive motors. The threaded rods extend into the slide grooves, and fixed splints are arranged outside the threaded rods.

[0008] The above technical solution is adopted, and the driving motor installed on the mounting plate is controlled by the controller, so that the driving motor drives the threaded rod installed on its output end to rotate. Then, because a fixed splint is provided on the threaded rod at the output end of the driving motor, and the fixed splint is provided in the slide groove, when the driving motor drives the threaded rod to rotate, the fixed splint will drop, thereby pressing the tape on the test table, thereby preventing the tape from being lifted up by the test plate when testing the viscosity.

[0009] Preferably, a mounting bracket is fixedly mounted on the mounting plate, the mounting bracket has an L-shaped plate structure, an electric telescopic rod is fixedly mounted on the mounting bracket, the electric telescopic rod and the controller are electrically connected, and a spring dynamometer is fixedly mounted on the zoom end of the electric telescopic rod.

[0010] By adopting the above technical solution, the controller is turned on to make the electric telescopic rod drive the spring dynamometer to descend, and then a test plate is installed under the spring dynamometer, so the protective cover at the bottom of the test plate will contact the tape fixed on the test table. Then, when the protective cover contacts the sticky surface of the tape, the staff controls the electric telescopic rod through the controller to drive the spring dynamometer to move upward. When the spring dynamometer moves upward, it will drive the test plate to move upward. In the process of separating the protective cover from the sticky surface of the tape, the reading will be displayed on the spring dynamometer, which can facilitate the testing of the viscosity of the tape.

[0011] Preferably, a mounting block is fixedly installed at the bottom of the spring dynamometer, a test plate is fixedly installed at the bottom of the mounting block, and two limiting rods distributed in opposite directions are fixedly installed on the test plate, and the limiting rods both penetrate the mounting frame.

[0012] By adopting the above technical solution, the two limit plates installed on the test plate can better ensure that the electric telescopic rod drives the test plate to remain stable when moving upward.

[0013] Preferably, a protective cover is provided outside the test plate, positioning holes are provided on the four end faces of the test plate and the protective cover, and positioning bolts are provided in the positioning holes.

[0014] By adopting the above technical solution, a protective cover is provided at the bottom of the test board, so that the glue on the tape can be better prevented from sticking to the bottom of the test board. Then the protective cover is installed on the test board through positioning bolts, so it is easy to remove it for cleaning.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The tape viscosity testing device places the tape to be tested on the test table, with the sticky side of the tape facing up, and then wraps both ends of the tape around the rotating roller. The staff then rotates the rotating roller to keep the tape flat on the test table. The controller then controls the drive motor installed on the mounting plate to drive the threaded rod installed on its output end to rotate, thereby causing the threaded rod to drive the fixed splint to descend, thereby pressing the tape on the test table to prevent the tape from being lifted by the test plate during the viscosity test.

[0017] 2. The tape viscosity testing device moves the test plate upward when the spring dynamometer moves upward. During the separation of the protective cover from the sticky surface of the tape, the reading will be displayed on the spring dynamometer, which makes it easy to test the viscosity of the tape. A protective cover is provided at the bottom of the test plate to prevent the bottom of the test plate from sticking to the adhesive on the tape. The protective cover is installed on the test plate through positioning bolts, so it is easy to remove it for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Working principle: The testing device can be supported by the four supporting legs 2 installed at the bottom of the base plate 1. Then, when it is necessary to test the viscosity of the produced tape, the tape to be tested is first placed on the test bench, and then the sticky side of the tape is facing up. Then, both ends of the tape are wrapped around the rotating roller 6. Then, the staff rotates the rotating roller 6 to keep the tape flat on the test bench 4, thereby improving the test effect. Then, the controller 3 is used to control the drive motor 8 installed on the mounting plate 5, so that the drive motor 8 drives the threaded rod 9 installed on its output end to rotate. Then, because a fixed splint 10 is provided on the threaded rod 9 at the output end of the drive motor 8, and the fixed splint 10 is provided in the slide groove 7, when the drive motor 8 drives the threaded rod 9 to rotate, the fixed splint 10 will drop, thereby pressing the tape on the test bench 4, thereby preventing the tape from being lifted by the test plate 15 when testing the viscosity.

[0027] Example 2:

[0028] Please refer to Figures 1-4, a tape viscosity testing device, a mounting frame 11 is fixedly mounted on the mounting plate 5, the mounting frame 11 has an L-shaped plate structure, an electric telescopic rod 12 is fixedly mounted on the mounting frame 11, the electric telescopic rod 12 and the controller 3 are electrically connected, a spring dynamometer 13 is fixedly mounted on the zoom end of the electric telescopic rod 12, a mounting block 14 is fixedly mounted on the bottom of the spring dynamometer 13, a test plate 15 is fixedly mounted on the bottom of the mounting block 14, two limiting rods 16 distributed in opposite directions are fixedly mounted on the test plate 15, the limiting rods 16 are all extended to the mounting frame 11, a protective cover 17 is provided on the outside of the test plate 15, and positioning holes 18 are provided on the four end faces of the test plate 15 and the protective cover 17, and positioning bolts 19 are provided in the positioning holes 18.

[0029] Working principle: When the viscosity of the tape needs to be tested, the controller 3 is turned on to make the electric telescopic rod 12 drive the spring dynamometer 13 to descend, and then the test plate 15 is installed under the spring dynamometer 13. Therefore, the protective cover 17 at the bottom of the test plate 15 will contact the tape fixed on the test table 4. Then, when the protective cover 17 contacts the sticky surface of the tape, the staff controls the electric telescopic rod 12 through the controller 3 to drive the spring dynamometer 13 to move upward. When the spring dynamometer 13 moves upward, it will drive the test plate 15 to move upward. During the process of separating the protective cover 17 from the sticky surface of the tape, the reading will be displayed on the spring dynamometer 13, which can facilitate the test of the viscosity of the tape and the judgment of the viscosity of the tape. Then the two limit plates installed on the test plate 15 can better keep the electric telescopic rod 12 stable when driving the test plate 15 to move upward. Then a protective cover 17 is provided at the bottom of the test plate 15, so it can better prevent the bottom of the test plate 15 from sticking to the adhesive on the tape. Then the protective cover 17 is installed on the test plate 15 by positioning bolts 19, so it is easy to remove it for cleaning.
