Mobile conveyor unit for high-speed sealing and cutting devices

Abstract

The invention discloses a mobile conveying assembly applied to a high-speed sealing and cutting device of a pillow packaging machine, comprising a frame (1), an input belt (2), and an output belt (11). Between the bottom and the bottom are connected successively through the input displacement transmission rod (4), the displacement eccentric seat (12), and the output displacement transmission rod (9). The displacement eccentric seat is installed on the displacement control shaft (24), and the displacement control shaft (24) Connect with the main drive assembly. In the present invention, the input displacement transmission rod and the output displacement transmission rod are driven by the displacement eccentric seat, so that the input belt and the output belt are firstly displaced to the left, and then to the right to make a lateral displacement, so as to realize the movable type of conveying to match the continuous sealing and cutting of the movement. , keep the heat seal for a certain period of time to ensure the heat seal effect. In this way, the overall sealing and cutting speed can be improved, reaching more than 180 pieces per minute, and the transportation is fast and smooth, and the production efficiency is high.

Description

technical field [0001] The invention relates to packaging machinery, in particular to a sealing and cutting device for a pillow packaging machine. technical background [0002] At present, the pillow packaging machine mainly includes a frame, an unwinding device, a material conveying device, a forming device, a middle sealing device, and a sealing and cutting device. To heat seal and cut the packaging film (with materials already loaded) that enters between the lower sealing knife and the upper sealing knife, in order to ensure the heat sealing effect, a certain heat sealing time is required, so the rotation speed of the rotary type lower sealing and cutting can only be reduced. The film is heat-sealed and cut at the same time, resulting in low work efficiency, generally about 120 pieces per minute. Its conveying components include input belt and output belt, which are fixed and not movable. Contents of the invention [0003] The object of the present invention is to ove...
