Description

Technical Field

[0001] The invention relates to the technical field of plastic product testing, in particular to a toughness testing device for recycled plastic products. Background Art

[0002] Recycled plastic products are a general term for daily necessities and industrial products made from recycled plastics as the main raw material, including products made from all processes such as injection molding and blister molding using plastics as raw materials. Plastic is a type of synthetic polymer material with plasticity. Together with synthetic rubber and synthetic fibers, it forms one of the three indispensable synthetic materials in daily life. The quality of the plastic products produced varies, and the products need to be tested for toughness.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed "a plastic product toughness testing device", and its application number is CN202221223381.6. The patent mainly provides a bending test mechanism. When the plastic product is clamped between the U-shaped frames, the fastening screws can be loosened, and then the slip ring can be slid. Under the sliding cooperation between the guide column and the slip ring, the second electric push rod is driven to move, so that the pressure head is facing the center position of the plastic product, and then the control panel is operated to control the second electric push rod to work. Under the action of the second electric push rod, the pressure head is driven to move downward to squeeze the plastic product and perform a bending test. Under the action of the second pressure sensor, the pressure value is transmitted to the surface of the control panel, realizing the bending test function of the test device on the plastic product, thereby improving the test accuracy when the test device is used. However, the above scheme is not convenient for automatic unloading when in use, and manual unloading is required, which increases the work steps and affects the test efficiency.
