Automatic reverse zipper head attaching mechanism

Abstract

The invention discloses an automatic reverse zipper head attaching mechanism. The automatic reverse zipper head attaching mechanism comprises a mounting baseplate, a main plate, bone clamp air cylinders as well as a material pushing air cylinder and a material channel, wherein the material channel is connected with the main plate through a feed inlet; vertical plates are mounted on the mounting baseplate and positioned at the side ends of the main plate; fixing plates are mounted at the upper ends of the vertical plates; a material pushing slide groove and at least three bone clamp grooves are formed at the upper end of the main plate; a material pushing device is mounted in the material pushing slide groove, and comprises a material pushing slide block connected with the material pushing air cylinder and a slide block seat arranged at the lower end of the material pushing slide block; a bag opening needle is arranged at one side end of the material pushing slide block; a bag opening needle slide seat positioned at the lower end of the bag opening needle is arranged at the upper end of the slide block seat; a bone clamp I, a bone clamp II and a bone clamp III which are connected with the bone clamp air cylinders are mounted in the bone clamp grooves; and the material pushing device is arranged in the material pushing slide groove between the bone clamp II and the bone clamp III. The automatic reverse zipper head attaching mechanism is novel in design, simple in structure, high in production efficiency and low in cost; and by adoption of the automatic reverse zipper head attaching mechanism, the habit that a sealing bag is closed or opened when a zipper head is pulled to the left or right can be met.

Description

technical field [0001] The invention relates to the technical field of sealing bag production equipment, in particular to an automatic reverse zipper head mechanism. Background technique [0002] The zipper ziplock bag is a common self-sealing packaging bag, also known as a sealed bag. Among them, in order to facilitate the operation of sealing / unsealing, the zipper ziplock bag usually adopts a zipper head to realize its automatic sealing. In the traditional production process, pull the zipper head to the right to open the mouth of the sealed bag, and pull the zipper head to the left to close the mouth of the sealed bag, but in production, when sealing the direction of the bag, if according to the traditional production process, Pulling the zipper to the right will cause the mouth of the sealed bag to close, and pulling the zipper to the left will open the mouth of the sealed bag, which does not meet the usage habits and causes inconvenience.
