An inflation device for a pillow packaging machine

Abstract

The invention discloses an air inflating device for a pillow type packaging machine. The air inflating device comprises a left longitudinal cover plate, a right longitudinal cover plate, an air inflating pipe, a right regulating device, a right limiting plate, a fixed block I, a lock screw I, a guide slot I, a fixed plate I, a right guide seat, a right guide wheel, a right conveying belt, an air inflating guide device, a left conveying belt, a left guide wheel, a left guide seat, a fixed plate II, a left limiting plate, a guide slot II, a fixed block II, a lock screw II and a left regulating device. The air inflating device has the advantages of the reasonable and simple structure, low production cost and convenience in mounting. The right conveying belt, the left conveying belt and the air inflating guide device are arranged, and therefore the two edges of a packaging bag can be simultaneously compressed effectively, and meanwhile the longitudinal movement of the packaging bag is notaffected. The outer side surfaces of the right guide wheel and the left guide wheel are convex arc surfaces, and the outer side surfaces of a left limiting wheel and a right limiting wheel are concavearc surfaces, therefore the whole air inflating guide device cannot move up and down when being used, and the deformation of the air inflating pipe is also avoided.

Description

Technical field: [0001] The invention relates to the field of mechanical packaging, in particular to an inflation device of a pillow packaging machine. Background technique: [0002] Pillow packaging machine is an indispensable and commonly used equipment in modern industrial automation production and packaging. Among them, there is a type of product that needs to be flushed with nitrogen during packaging to keep fresh, especially for soft products such as bread and cakes. Filling the air inside can reduce the mutual extrusion and deformation of the products and affect the appearance. Therefore, when packaging such products, it is necessary to install an inflatable device on the packaging machine according to the customer's needs; and the inflatable device is to install an inflatable tube at the middle seam of the longitudinal sealing plate of the packaging machine. Plane cushion strips are respectively arranged on the longitudinal cover plates on both sides of the inflation...
