[0002] In the field of modern industrial production and commodity circulation, flexible packaging materials are widely used in many industries such as food, medicine, daily chemicals, and electronics due to their advantages such as light weight, relatively low cost, easy processing and molding, and adaptability to diverse product shapes. Common plastic films, paper soft packaging materials, composite packaging bags, etc. are all typical forms of flexible packaging. However, the mechanical properties of flexible packaging materials are special. Compared with rigid packaging, their strength characteristics are complex and changeable due to the influence of materials, thickness, and processing technology. In actual use scenarios, when facing working conditions such as handling, stacking, and transportation vibration, problems such as cracking and excessive stretching caused by insufficient strength are prone to occur, endangering product quality and shelf life.

It is based on fixed fixtures and rigid loading structures, and the testing mode is stereotyped. It is difficult to adapt to the characteristics of flexible packaging materials that are soft, deformable, and susceptible to tensile stress damage, which seriously restricts the quality control and process improvement of flexible packaging. Therefore, it is urgent to develop a high-precision, multi-functional, and highly adaptable flexible packaging material strength testing equipment. Summary of the invention

After the winding roller 305 rotates along the inner annular groove 202 for one circle, the pressing position is released. The winding roller 305 continues to rotate along the inner annular groove 202 for several circles. After the collection and fixing of the multi-layer flexible packaging material is completed, the second driving member 307 is operated to drive the first anti-slip roller 308 to move to the side close to the winding roller 305 to complete the winding. The flexible packaging material on the roller 305 is pressed and fixed. When the first driving member 301 drives the first connecting rod 303 to rotate, it can drive the second connecting rod 304 to rotate circumferentially. When the second connecting rod 304 rotates circumferentially, it can drive the heating member 309 to rotate synchronously along the outer ring groove 203. When the heating member 309 is turned on, the flexible packaging material wound on the outside of the flexible packaging material collecting and covering device 4 can be heated, and then the performance of the flexible packaging material at different temperatures can be detected. A colloid is coated on the outside of the first adhesive roller 405.

After the winding roller 305 rotates one circle along the inner ring groove 202, the pressing position is released, and the winding roller 305 rotates several circles along the inner ring groove 202. The flexible packaging material is wound around the outer sides of the first adhesive rollers 405. When the flexible packaging material is wound, the third driving members 402 move to the end away from the middle seat 401, and cooperate with the transmission rod 406 to drive the support rods 404 and the first adhesive rollers 405 outside to unfold, further expand the tension of the flexible packaging material wound around the outer sides of the first adhesive rollers 405, and detect the multi-point support bearing capacity of the flexible packaging material.

[0045] When the flexible packaging material is wound, the fourth driving member 602 can drive the puncture cone 603 to move toward one side of the wound flexible packaging material, so that the puncture cone 603 contacts the flexible packaging material, and then gradually increase the puncture force of the puncture cone 603 to complete the puncture bearing capacity detection of the flexible packaging material, move the material control device 3 along the inner ring groove 202 to a position near the fixed seat 701, and stick the movable end of the flexible packaging material to the second adhesive roller 702, and then the fifth driving member 704 drives the second anti-slip roller 706 to move toward the side close to the second adhesive roller 702, so that the second anti-slip roller 706 presses and fixes the flexible packaging material pasted on the outside of the second adhesive roller 702, and then the material control device 3 continues to move along the inner ring groove 202 to detect the unidirectional support bearing capacity of the flexible packaging material.
