Automatic two-way blank-pressing ton bag machine

Abstract

The invention discloses an automatic two-way blank-pressing ton bag machine. The automatic two-way blank-pressing ton bag machine comprises two machines, namely an I type machine and an II type machine which are connected, wherein both the I type machine and the II type machine are ton bag machine bodies; each of the I type machine and the II type machine comprises a rack, a first air cylinder, a second air cylinder, a third air cylinder, a fourth air cylinder, a fifth air cylinder, a supporting mechanism, a floating plate, a pressure head, a plug board, a linear guide rail pair, a sucking disc, an upper heating knife and a lower heating knife. The automatic two-way blank-pressing ton bag machine is high in degree of automation, and can complete the whole action by switching on and off once, so that the working efficiency is greatly improved; an automatic gas sucking device is arranged for separating upper and lower sheets of a bag body so as to plug in the plug board conveniently, so that the firmness and the flatness of a welding seam are guaranteed; and welding is completed once, so that labor power is reduced, the labor intensity of a worker is reduced, and the working efficiency and the product quality are improved.

Description

technical field [0001] The invention relates to the field of packaging machinery, in particular to an automatic two-way crimping big bag machine. Background technique [0002] The aluminum-plastic composite ton bag is used for the packaging of 500kg-1000kg powder and granules. It is famous for its large bag size, but the production process of the ton bag is complicated, and there are many subsequent processes, which are basically completed by workers. Such as figure 1 , figure 2 , image 3 As shown, the aluminum-plastic composite ton bag is composed of upper, lower, left and right pieces, and the left and right pieces are folded into edges. When ironing the neck and bottom, according to the traditional process, only the front and back of the two large bag machines can only be ironed twice on the front and back of the neck and the eight-character bottom. The positive and negative secondary ironing on the big bag machine. The output is low, the efficiency is low, the qua...
