Description

Technical Field

[0001] The present invention relates to the technical field of quality inspection of composite bags, and particularly to a quality inspection platform for the tensile strength of composite bags that is convenient for fixing. Background Art

[0002] A composite bag is a packaging bag composed of two or more different materials combined through one or more composite processes. Such materials usually include plastic films, papers, aluminum foils, etc., which are bonded together by adhesives, heat melting or other means. During the production process of composite bags, a quality inspection platform is required to detect the tensile strength of composite bags, which can accurately evaluate the tensile properties of composite bag materials, thereby determining whether the composite bags meet the usage requirements.

[0003] In the prior art, when conducting quality inspection on the tensile strength of composite bags, a unidirectional tensile test is usually carried out on the bag mouth and the supporting parts at the bottom of the composite bag. However, during the handling, stacking, and transportation vibration processes of composite bags, the two sides of the composite bags also bear the action of composite stress. Therefore, the results obtained from the unidirectional tensile test are difficult to comprehensively evaluate the tensile strength of composite bags. When detecting the lateral parts of the same composite bag, the local plastic deformation caused by the first test will significantly reduce the reliability of the second clamping, and manual repeated calibration and positioning are required, resulting in a significant reduction in the operation efficiency of composite bag quality inspection.

When the movable positioning frame 1 is above the temperature control water tank 101, the tensile strength of the composite bag can be detected at room temperature. The drive cylinder at the top of the fixed support plate 102 drives the four end corners of the movable positioning frame 1 to move downward along the guiding vertical rod 103, so that the movable positioning frame 1 is immersed in the water inside the movable positioning frame 1.

By simulating the use condition of the composite bag in a colder environment, the tensile strength of the composite bag in a colder environment can be tested. The test of the composite bag can be completed at different temperatures, and the test results are relatively comprehensive, fully testing the tensile strength quality of the composite.

When the movable positioning frame 1 is above the temperature control water tank 101, the tensile strength of the composite bag at room temperature is detected. The driving cylinder at the top of the fixed support plate 102 drives the four end corners of the movable positioning frame 1 to move downward along the guiding vertical rod 103.

After being heated, it is evenly heated through the side diversion pipe 109 of the water outlet pipe 108 to test the tensile strength of the composite bag in a relatively hot environment. When the refrigeration driving pump 105 operates and the heating driving pump 104 stops working, the water flow inside the temperature control water tank 101 enters the water inlet pipe 106 through the diversion pipe 107 and then flows into the refrigeration driving pump 105.
