Abstract

Provided is a driving device for bag expanding boards. According to the driving device for the bag expanding boards, two guide rods of the bag expanding boards are hinged to the working ends correspondingly, and one side of each guide rod is provided with a small air cylinder which is fixed to the guide rod in parallel. The driving device for the bag expanding boards is characterized in that the front end of a piston of each small air cylinder is connected with the corresponding bag expanding board through a bulb pull rod, and the connection point and a hinge shaft of each bag expanding board and the corresponding guide rod are uncoaxial. The reliability of the driving device for the bag expanding boards is effectively improved, the service life of the driving device for the bag expanding boards is effectively prolonged, and the control efficiency is improved.

Description

technical field [0001] The invention relates to a driving device for a bag spreader, which belongs to the field of mechanical manufacturing. Background technique [0002] The bag stretcher of the automatic packaging machine has a mechanical action that extends into the packaging bag. The conventional driving method often uses two different-axis drive rods to drive the bag stretcher. However, the traditional driving rod basically adopts an elastic structure, and its reliability and service life are not high. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a driving device for a pocket spreader with high reliability and long service life. [0004] Technical scheme of the present invention is: [0005] The driving device of the bag-stretching plate includes two guide rods with a bag-stretching plate hinged at each working end. One side of the guide rod is provided with a small cylinder fixed and parallel to the guid...
