Bag mouth guide device preventing falling of bag mouth

Abstract

The invention discloses a bag mouth guide device preventing falling of a bag mouth. The bag mouth guide device comprises an installing seat. A gear motor is installed on the installing seat. Two universal couplings are connected to the lower end of the gear motor and are distributed symmetrically front and back. Support plates are symmetrically connected to the front and rear sides of the lower end of the installing seat through struts. Swing arms are connected to one ends of the support plates. The lower sides of the support plates and the swing arms are jointly connected with a synchronous belt. The bag mouth guide device is matched with a lower conveying mechanism, a packing bag sent by a bag mouth clamping mechanism can be conveyed into a bag sewing mechanism, a connecting link function is achieved, falling of the bag mouth can be prevented, and the next step of smooth work is ensured.

Description

technical field [0001] The invention belongs to the field of packaging equipment, and in particular relates to a bag mouth guiding device for preventing the bag mouth from falling down. Background technique [0002] In the actual production process, after filling the packaging bag, it needs to be sewn by the sewing mechanism. However, if the mouth of the packaging bag is lodging or the mouth of the bag is not neat, the sewing work will not be carried out normally, causing the production line to stagnate or the sewing mechanism to be damaged. At present, most of the pockets of the packaging bags are manually sorted or V-belt guiding devices are used. The former has a large workload, low efficiency and high labor costs. When the V-belt is compressed and opened, materials will be scattered into the inside of the V-belt. The V-belt is easy to fall off, and the speed of the two V-belts clamping the bag is not easy to synchronize, which will cause the pocket mouth to stagger, thus...
