This invention discloses a method for preparing a modified chitosan whisker-reinforced and toughened PBAT microfoamed composite material. Biodegradable and high-modulus chitosan whiskers are selected as the reinforcing agent, enabling the composite material to achieve full biodegradability. Through surface modification technology, PBAT segments with the same composition as the PBAT matrix are introduced onto the surface of the chitosan whiskers. This design ensures good compatibility between the chitosan whiskers and the matrix, resulting in thorough dispersion within the matrix and achieving a more efficient reinforcement and toughening effect than traditional reinforcing agents. Simultaneously, the grafted and modified chitosan whiskers can increase the melt viscosity and melt strength of the PBAT matrix, thereby improving its foaming properties.

This utility model discloses an adhesive sealing device, belonging to the field of packaging sealing technology. It includes a sealing mechanism comprising two folding sections and an adhesive tape pasting section. Each folding section includes an upward control lever and a gathering control lever. The two upward control levers are used to control the upward folding of excess packaging film. The two gathering control levers can move towards each other in the left-right direction via corresponding first slide rails, so that the excess packaging film after folding is compressed and gathered by the two gathering control levers. The two folding sections can move backward synchronously, so that the gathered excess packaging film is folded around the periphery of the roll to be sealed by the obstruction of the two upward control levers. The adhesive tape pasting section is used to cooperate with a roller to paste and wrap adhesive tape around the periphery of the roll to be sealed. This adhesive sealing device aims to solve the problem in the prior art where heat sealing of roll packaging makes it difficult to reuse or repackage the film, significantly improving the convenience and flexibility of packaging.

This invention relates to the field of robot end effector technology, specifically to a cable-driven multi-dimensional helical actuator and its manufacturing method, including a drive base and a coiling actuator module; the coiling actuator module is mounted on top of the drive base, and the drive base provides coiling power to the coiling actuator module.
