Device for testing tension of adhesive tape

Abstract

The invention relates to a device for testing the tension of an adhesive tape. The device comprises a base, wherein one end of the base is provided with a cylinder; a left clamping device used for clamping the adhesive tape is arranged at the left side of the base, and a right clamping device used for clamping the adhesive tape is arranged at the right side of the base; the left clamping device comprises a left lower first fixed shaft and a left lower second fixed shaft which are respectively supported by two left lower brackets; one sides of the two left lower brackets are respectively connected with a left upper bracket by a hinge; a left upper first fixed shaft and a left upper second fixed shaft are respectively supported by the two left upper brackets; the right clamping device comprises a right lower first fixed shaft and a right lower second fixed shaft which are respectively supported by two right lower brackets; one sides of the two right lower brackets are respectively connected with a right upper bracket by a hinge; a right upper first fixed shaft and a right upper second fixed shaft are respectively supported by the two right upper brackets. The device is simple in structure, reasonable in design and convenient to operate; the tensile strength of the adhesive tape can be tested by the simple device.

Description

technical field [0001] The invention belongs to the technical field of tape processing, and in particular relates to a tension test device for tapes. Background technique [0002] Adhesive tape is composed of base material and adhesive. Two or more unconnected objects are connected together by bonding. A layer of adhesive is coated on its surface. The adhesive can stick things because of its own The molecules and the molecules to be connected form a bond, which can firmly bond the molecules together. In daily use, there are many different specifications such as single-sided and double-sided, and the tape needs to be Do a series of tests on the properties of the tape, such as initial adhesion, durability, and strength and tensile tests, etc. The current test is generally to put the shorter one on the fixture and see the tensile force when the tape breaks, but due to the special nature of the tape Sticky, slippery, etc., it is inconvenient to fix, and the test results are...

[0002] Adhesive tape is composed of base material and adhesive. Two or more unconnected objects are connected together by bonding. The surface is coated with a layer of adhesive. The adhesive can stick things because of its own Bonds are formed between the molecules and the molecules to be connected. This bond can firmly bond the molecules together. In daily use, there are many different specifications such as single-sided and double-sided, and the tape needs to be sold before it is sold. Do a series of tests on the properties of the tape, such as initial adhesion, durability, and strength and tensile tests, etc. The current test is generally to put the shorter one on the fixture and see the tensile force when the tape breaks, but due to the special nature of the tape Sticky, slippery, etc., it is inconvenient to fix, and the test results are easily affected by the weather, especially when the temperature is very low in winter, the tape is easy to be pulled off, which affects the test results
