Anti-freezing solution filling system

Abstract

The invention discloses an anti-freezing solution filling system. The anti-freezing solution filling system comprises a filling head shell and a filling pipe, wherein an anti-freezing solution fillingport connector is fixedly arranged at the upper end of the filling head shell in a sealed mode; the upper end of the filling pipe is fixedly connected to the anti-freezing solution filling port connector; the lower end of the filling pipe penetrates through an inner cavity of the filling head shell and extends out of the lower end of the filling head shell to form an extending section; a gap is arranged between the lower end in the filling head shell and the filling pipe; a through hole is arranged in the anti-freezing solution filling port connector and communicated with the filling pipe; and a vacuum pumping connector, an anti-freezing solution recycling connector and a liquid level sensor used for measuring the liquid level in the gap are arranged on the filling head shell. A product is directly filled with an anti-freezing solution, residual air after filling is extruded into the inner cavity of the filling head shell by the anti-freezing solution, two-time filling is not needed,and the efficiency can be greatly improved. Meanwhile, the filling pipe goes deep into the product, so that the residual air is extruded out of the inner cavity of the product, and the defect that theanti-freezing solution is not fully filled is effectively prevented.

Description

technical field [0001] The invention relates to antifreeze filling technology, in particular to an antifreeze filling system. Background technique [0002] In the automobile manufacturing industry, the shock absorption system is essential. Among them, the shock absorber is the key component of the shock absorption system. [0003] Rubber shock absorbers are one of the major categories, and there are many products in rubber shock absorbers that need to be filled with antifreeze inside the shock absorber. The injection of antifreeze is an important process in the shock absorber industry, so it is of great significance to improve the injection efficiency and quality of antifreeze. [0004] At present, most of the antifreeze filling adopts the vacuum filling process, because it is poured directly from the product injection port, so after the first filling, the inside of the product cannot be filled with antifreeze, and there is residual air above, so it needs to be vacuumed ag...
