Automatic weight adding and adjusting device for fusion index meter

Abstract

An automatic weighting adjustment device for a melt index meter, comprising an index meter piston rod body (1), the rod body (1) is connected to a weighted part through a bracket structure (2) and includes a display device (3), a pressure chamber (4), two An air pressure regulator (5), an air pressure sensing module (6), a control panel (7) located on the upper surface of the cavity, and an input device (8), a code-to-digital converter (9), and a peeling device (10) are arranged inside. When connected with the piston rod, the load operation is carried out by regularly adjusting the internal air pressure state according to the test requirements, and the display device (3) is used to display the weight level; the prompt device (11) is set, and when the added weight reaches the set weight level, a corresponding alarm will be issued. Prompt information; the structure design is simple, and the conversion of the weight level is realized by adjusting the air pressure. The adjustment is convenient and can effectively speed up the progress of the experiment. At the same time, the operation is simple, the weight is uniform, and it is economical and practical.

Description

technical field [0001] The invention relates to a melt index meter. Background technique [0002] In the detection of the mass flow rate of plastic melt, the structure and function of the melt index meter are precisely designed, and the test effect is obvious, but there are also certain shortcomings in the actual operation process. Manual coding operation is used, and the experimenter needs to perform regular and quantitative replacement operations. This method affected the overall progress of the experiment. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a melt indexer with automatic coding and comprehensive adjustment functions. [0004] The present invention is realized in this way. An automatic coding adjustment device for a melt indexer, comprising an indexer piston rod body, the rod body is connected with a weighted component through a bracket structure, and includes a display device, a pressure cavity, two air pressure regulat...
