[0002] Plastic is a material made of high molecular polymers, characterized by its lightweight, durability, and high plasticity, and is widely used in various fields. During plastic production, tests are required to assess properties such as high-temperature softening and tensile strength. High-temperature softening tests utilize high-temperature testing equipment. However, some existing high-temperature testing equipment uses open flame combustion, which, while fast, produces a significant amount of harmful gases. Others use high-temperature ovens, but these methods easily cause the plastic to melt, are difficult to clean, and have low environmental performance. In light of these issues, the inventor has developed a new invention. Utility Model Content

Detailed Implementation

[0015] The following is in conjunction with the appendix Figures 1 to 2 This utility model will be described in detail.

[0016] This utility model discloses a high-temperature softening test device for plastics with high environmental performance, comprising a clamping mechanism 1 and a test mechanism 2. The clamping mechanism 1 is provided with a positioning seat 11, and the positioning seat 11 is sequentially provided with a rotating rod 12, a motor 13 for driving the rotating rod 12, and a connecting plate 3 connected to the rod body of the rotating rod 12. The connecting plate 3 is provided with a notch 31 that allows the front and rear sides of the connecting plate 3 to communicate with each other. The connecting plate 3 is provided with a material groove 32 on the upper and lower sides of the notch 31, and a movable positioning plate 33 is provided on the material groove 32. The test mechanism 2 is provided with a control box 21, which is provided with a long strip-shaped heating component 22 and a pressure sensor 23. The motor 13 can drive the connecting plate 3 to swing, so that the notch 31 passes through the heating component 22. In this invention, a plastic sheet is placed in a material trough 32, and a positioning plate 33 fixes the plastic sheet in place. Then, a motor 13 drives a connecting plate 3 to swing downwards, causing the plastic sheet to contact the heating element 22. The control box 21 then provides electrical energy to gradually heat the heating element 22 until it softens the plastic sheet. During the softening process, the motor 13 continuously provides a small driving force, causing the softened plastic sheet to be deformed by the heating element 22. At this point, the connecting plate 3 can continue to move and contact the pressure sensor 23. Finally, the heating element 22 stops heating, and the high-temperature softening test of the plastic is completed. This experimental device softens the plastic sheet by heating the element 22 without producing open flames, reducing the generation of burning fumes. Furthermore, even after heating stops, the plastic sheet will not melt, resulting in high environmental performance.

[0017] One side of the material trough 32 is provided with a guide groove 34 for the positioning plate 33 to move, and the other side of the material trough 32 is provided with a through hole 35. The positioning plate 33 is provided with a connecting rod 36 that passes through the through hole 35 and extends to the outside of the connecting plate 3. In this structure, by pushing the connecting rod 36, the positioning plate 33 can move between the guide groove 34 and the material trough 32, and the plastic sheet can be placed in the material trough 32 for quick positioning without adjusting the direction of the plastic sheet, making it convenient to put in and take out the material.

[0018] A pull rod 37 is provided between the two connecting rods 36. To prevent the plastic sheet from loosening, two material troughs 32 are provided, which are used to fix the opposite ends of the plastic sheet respectively. The positioning plate 33 and the connecting rod 36 are also provided separately. The two connecting rods 36 are connected as one unit by the pull rod 37. The operator can drive the two positioning plates 33 at the same time by pushing or pulling the pull rod 37, which is convenient to use.

[0019] The control box 21 is equipped with a heat insulation block 24, and the heating component 22 is fixed on the heat insulation block 24. The heat insulation block 24 is made of ceramic, which can prevent the high temperature generated by the heating component 22 from being conducted to the control box 21.

[0020] The connecting plate 3 has an arc-shaped movement trajectory. When the connecting plate 3 contacts the end of the pressure sensor 23, a small amount of friction will be generated. Prolonged use may easily damage the pressure sensor 23. Considering this, a slider 38 is provided on one side of the connecting plate 3. In this solution, the slider 38 is made of polished metal sheet. The smooth surface of the slider 38 greatly reduces the coefficient of friction when the connecting plate 3 contacts the pressure sensor 23, thereby improving its service life.

[0021] The clamping mechanism 1 is provided with a fixed base 14, and the fixed base 14 is provided with a lifting device 15. The positioning seat 11 is connected to the lifting device 15. Both the clamping mechanism 1 and the testing mechanism 2 are installed inside the chassis of the high-temperature testing machine. The fixed base 14 is fixedly installed at the top position inside the chassis of the high-temperature testing machine, so that the clamping mechanism 1 is fixed above the testing mechanism 2 at an angle. The height of the connecting plate 3 can be adjusted by the lifting device 15, thereby adjusting the position of the heating component 22 in contact with the plastic sheet.

[0022] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this invention. The content of this specification should not be construed as a limitation of this utility model.
