Problems solved by technology

[0002] During sealing, the valve needle is fixed by the thrust of the cylinder piston. Due to the high sealing pressure, the compressed air chamber of the existing cylinder structure is small, and the thrust is not enough when the piston moves, causing the valve needle to retreat, and the glue port cannot be sealed. affect product quality

Abstract

The invention discloses a pull rod type single-point valve needle cylinder, which comprises a cylinder body, a cylinder bottom cover, a connecting rod and a piston arranged between the cylinder body and the cylinder bottom cover; the cylinder body comprises a cylinder block and a boss arranged on the cylinder block; the piston is inserted in the boss of the cylinder body; the cylinder bottom cover is fixed on the cylinder body, and covers the piston; a compressed air chamber is formed between the piston, the cylinder body and the cylinder bottom cover; the cylinder body is provided with a pull rod-fixing hole corresponding to the position of the piston, and a pull rod runs through the pull rod-fixing hole to fixedly connect with the piston. By means of the method, the pull rod type single-point valve needle cylinder can increase the pushing force of the moving piston, a valve needle does not move back, and adhesive opening sealing is table; cylinder cooling is rapid, and the working state is stable.

Description

technical field [0001] The invention relates to the field of high-pressure cylinders, in particular to a rod-type single-point valve needle cylinder. Background technique [0002] During sealing, the valve needle is fixed by the thrust of the cylinder piston. Due to the high sealing pressure, the compressed air chamber of the existing cylinder structure is small, and the thrust is not enough when the piston moves, causing the valve needle to retreat, and the glue port cannot be sealed. affect product quality. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a rod-type single-point valve needle cylinder, which can increase the thrust of the piston during movement, the valve needle will not retreat, and the glue seal is stable; the cylinder is cooled quickly and the working state is stable. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention ...
