Cap screwing mechanism for full-automatic cap screwing machine

Abstract

The invention relates to the technical field of bottle packaging, and discloses a cap screwing mechanism for a full-automatic cap screwing machine. The cap screwing mechanism comprises a cap pressinghead, a suction cup, a motor and an air cylinder, the cap pressing head is a cylinder with a hollow inner cavity, the suction cup is located at the top of the cap pressing head, and a rotating shaft of the motor is fixedly connected to the top surface of the cap pressing head; and the fixed end of the air cylinder is connected to a rack, the extending end of the air cylinder is connected with themotor, an air pressure balance cavity is formed in the top of the capping head and connected with an air pump through a pipeline, and the suction cup is arranged on the bottom face of the air pressurebalance cavity. According to the cap screwing mechanism, a spiral groove is formed in the inner wall of the cap pressing head and is matched with airflow flowing upwards along the spiral groove to apply reverse rotating force to a bottle cap, the inclined bottle cap is promoted to be reversely screwed out of a bottle body, the situation that threads are abraded when the bottle cap is directly taken out upwards is avoided, and the bottle cap and the bottle body are both protected.

Description

Technical field [0001] The present invention relates to the technical field bottle package body, in particular to a rotary mechanism with automatic capping machine. Background technique [0002] Capping machine, also known as capping machine, for rotating the bottle is screwed to a mechanical, conventional capping machine includes a cap sorting mechanism, capping mechanism, and top cover means, cover means for processing the clutter flap cap organized into a downward direction, the cover mechanism for finishing a good bottle at the bottle placed in a capping mechanism for the cap of the bottle and the bottle is rotated downward screwed. Capping cylinder mechanism is generally used to promote motor down, the motor driving a screwing rotation direction toward the cap until the cap tightened. [0003] When the cover means cover a bottle, can not guarantee that the cap will be placed horizontally on the bottle, and the bottle and the cap due to the threads, results in a relatively fr...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing capping mechanism proposed in the background technology, the present invention provides a capping mechanism for a fully automatic capping machine, which has the advantages of correcting the position of the bottle cap and not wearing out the thread, and solves the above problems. The problem of the crooked bottle cap proposed in the background technology
