Paper-folding cam ejector for pocket tissue packing and method

Abstract

The invention discloses an origami cam ejection device for handkerchief paper packaging, which includes a central shaft, a flower roller, a cam assembly, a cam ejection assembly and a gas distribution plate; the invention uses a nylon cam to reduce the rolling bearing in the cam groove The disadvantages of high noise and poor lubrication during rolling; by adopting the structure that the return angle of the cam groove is greater than the push angle, the impact on the cam groove when the cam is pushed out of the assembly is reduced, and the service life of the cam is improved; the gas distribution plate and The cams are respectively set on both sides of the flower roller, which makes the design of the machine simpler and more compact. The invention also discloses an origami cam ejection method for handkerchief paper packaging, which includes the following steps: 1) the cam ejection assembly rotates with the flower roller; 2) the ejection movement of the cam ejection assembly; 3) Shockless retraction movement of the cam ejector assembly. Therefore, the present invention makes the packaging mechanically less impactful, applicable to different specifications, high in production efficiency, and long in service life.

Description

technical field [0001] The invention relates to the field of handkerchief paper packaging, in particular to an origami cam ejection device for handkerchief paper packaging. Background technique [0002] Because of its simplicity, convenience, and ease of carrying, small packs of handkerchiefs have become an indispensable part of people's daily lives. The production process of handkerchief paper generally includes the steps of embossing, cutting, folding, conveying, wrapping, corner folding, side sealing, end sealing and labeling. After the side sealing is completed, the handkerchief paper packet is ejected by the cam ejector , go to the next step. For example, the Chinese patent with the publication number CN200920064480.2 discloses a push bag device of a handkerchief paper packaging machine, which pushes the handkerchief paper packet out of the packing wheel through the roller of the push bag mechanism doing reciprocating linear motion in the cam groove. The groove struct...

Problems solved by technology

For example, the Chinese patent with the publication number CN200920064480.2 discloses a push bag device of a handkerchief paper packaging machine, which pushes the handkerchief paper packet out of the packing wheel through the roller of the push bag mechanism doing reciprocating linear motion in the cam groove. The groove structure, but its trajectory is a specific pear-shaped curve, and the push-out and retraction are completed quickly, which is prone to impact. In addition, in the push-pack device, the crossbar is connected with the push rod and the guide rod by two pins, so although it can It plays the role of connection and fixation, but the installation and structure are complicated. The suction device and the cam are installed on the same side, and the internal gear is installed on the other side, which makes the overall structure not compact enough, a lot of space is wasted, and the center of gravity is biased towards one side
