Three-dimensional bag demoulding device and forming demoulding method for three-dimensional bag

Abstract

Disclosed are a three-dimensional bag demoulding device and a forming demoulding method for a three-dimensional bag. The problem that existing forming devices for three-dimensional bags are not provided with demoulding devices is solved. The three-dimensional bag demoulding device comprises a forming mould and a demoulding mechanism. The forming mould has a first position used during installation and a second position facilitating processing of the three-dimensional bag. The demoulding mechanism comprises a demoulding frame. The demoulding frame is provided with a demoulding part and a demoulding driving part. The demoulding part has a first state achieved during installation and a second state achieved when the three-dimensional bag and the forming mould are separated under the driving of the demoulding driving part. The forming demoulding method for the three-dimensional bag includes the fourth step that the demoulding frame gets close to the forming mould so as to make the demoulding part be in contact with the outer surface of the three-dimensional bag, and a pushing assembly retracts; and the fifth step that the forming mould retracts to the installation position, the demoulding part acts to make the formed three-dimensional bag be separated from the forming mould, and separation between the three-dimensional bag and the forming mould is completed. The three-dimensional bag demoulding device further has the advantages of being simple in structure, convenient to assemble, reliable in action, long in service life and the like.

Description

technical field [0001] The invention relates to a three-dimensional bag processing equipment, in particular to a three-dimensional bag demoulding device and a molding and demoulding method of the three-dimensional bag. Background technique [0002] Non-woven bags have the characteristics of environmental protection and practicality, and have been vigorously promoted and used in recent years, which has promoted the rapid development of non-woven bag-making automatic forming technology. The existing non-woven three-dimensional bag is processed and formed by a three-dimensional bag forming machine at one time. During the processing, it is necessary to process the flat non-woven fabric into a cuboid through a forming device through a mold lifting device. When the non-woven fabric is pressed down by the mold, it is necessary to set up a bottom inserting device to fold the paper that exceeds the bottom of the mold upwards, and then use the side inserting devices on the left and ri...
