Abstract

The invention provides a device capable of distracting a bag opening. The device comprises a horizontal air cylinder, a vertical air cylinder, a sliding guide rail and a connecting rod mechanism, wherein the connecting rod mechanism comprises a support frame, a friction rod, a connecting rod and a bag opening ring; the support frame is of an L-shaped structure, the vertical side of the support frame is connected with the horizontal air cylinder, and the horizontal side of the support frame is connected with the bag opening ring through a rotary shaft; the sliding guide rail is connected with the vertical air cylinder; one end of the friction rod is arranged in the sliding guide rail, and the other end of the friction rod is connected with the horizontal side of the support frame through the rotary shaft; and the connecting rod is connected with the friction rod and the bag opening ring to form a double-rocker mechanism. The device capable of distracting the bag opening realizes automation of bag opening distraction, improves the efficiency of bag opening distraction, reduces the damage quantity of a packaging bag during the process of bag opening distraction, and improves the processing precision.

Description

technical field [0001] The invention relates to the field of packaging bags, in particular to a device for opening the mouth of a bag. Background technique [0002] In the field of engineering, there are many products that need to be packed into round-mouth packaging bags. Usually, since the mouth of the packaging bag is closed, in order to meet the requirements of product packaging, it is necessary to make the mouth of the packaging bag completely round. At the same time, in order to improve the opening of the bag Efficiency, to realize automatic bag opening, need a kind of device that makes round-mouth packaging bag bag opening open. Contents of the invention [0003] The object of the present invention is to provide a device for opening the bag mouth, so as to solve the problems that the existing sucker-type bag opening device has a limited range of use and the shape of the bag opening is not regular. [0004] In order to solve the above-mentioned technical problems, t...
