Problems solved by technology

[0009] The purpose of the present invention is to overcome the defects of the negative pressure device existing in the existing packaging machine when the bag is opened and opened, which has a large working load and high energy consumption, and the bag opening action cannot be carried out smoothly and the bag burst due to insufficient delivery of the prefabricated bag. The invention provides a bag receiving and stretching device for a packaging machine, which can reduce the work load of the negative pressure device and reduce energy consumption, and the prefabricated bags can be accurately transported to the bag opening and stretching station, avoiding the failure of the prefabricated bag The bag opening action caused by conveying in place cannot be carried out smoothly and the phenomenon of bag bursting occurs

Abstract

The invention discloses a bag receiving and opening device of a packing machine, and belongs to the field of packing machines. The device comprises a bag receiving and conveying mechanism and a bag opening mechanism; the bag receiving and conveying mechanism includes a bag bearing plate, and a translation mechanism capable of enabling the bag bearing plate to perform a reciprocating motion between a bag receiving station and a bag opening station; the bag bearing plate is provided with an absorbing hole in one side corresponding to the position of a bag opening of a prefabricated bag; the bag opening mechanism includes a bag opening jaw; and the side surface of the bag opening jaw is arched. The device can reduce the working load of a negative pressure device, reduces the energy consumption, and can accurately convey the prefabricated bag to the bag opening station to prevent the phenomenon of incapability of smooth actuation of the bag opening action and the bag blasting phenomenon caused by incapability of conveying the prefabricated bag in place.
