Bottle cap screening device and method

Abstract

The invention discloses a bottle cap screening device and method. The bottle cap screening device comprises a connecting plate, a first guard plate, a second guard plate, an upper guard plate and a lower guard plate, wherein a bottle cap inlet is formed in the connecting plate; the first ends of the first guard plate and the second guard plate are oppositely arranged on the left side and the right side of the bottle cap inlet; the first end of the upper guard plate is arranged on the upper side of the bottle cap inlet; the first end of the lower guard plate is arranged on the lower side of the bottle cap inlet and is arranged near the first guard plate; a space formed by the first guard plate, the second guard plate, the upper guard plate and the lower guard plate is a screening passage; a screening opening is formed between the lower guard plate and the second guard plate; the width of the screening opening is smaller than the thickness of a bottle cap with an anti-theft ring, and is greater than or equal to the thickness of the bottle cap which loses the anti-theft ring; a side blowing gas nozzle which blows towards the second guard plate is arranged on the first guard plate. The bottle cap screening device and method can quickly and accurately screen the bottle cap which loses the anti-theft ring, so that the situation that unqualified products appear is avoided.

Description

technical field [0001] The invention relates to bottle cap screening technology, in particular to a bottle cap screening device and method. Background technique [0002] The bottle cap of the beverage bottle is generally composed of the bottle cap body and the anti-theft ring. There is a ring-shaped tear line between the bottle cap body and the anti-theft ring. After the bottle cap is rotated for the first time, the tear line needs to be torn to open. The body of the bottle cap plays a role in ensuring the safety of the product. With the development of technology, automation technology is widely used in production, such as the capping machine that realizes automatic capping, etc. If the bottle caps with missing anti-theft rings are not screened out in time before the caps enter the capping machine, the product will not be Qualified, or even cause damage to the equipment. Contents of the invention [0003] Based on this, it is necessary to address the defects of the prior...
