a folding mechanism

Abstract

The invention discloses an edge folding mechanism. The edge folding mechanism comprises a plurality of transversely-arranged bases, a first edge folding plate is pivoted to each base through a transverse first pivot shaft, the outer lateral face of each first edge folding plate can be pushed by a longitudinally-moved push rod to enable the first edge folding plate to rotate around the corresponding first pivot shaft, a second edge folding plate is further pivoted to each first edge folding plate through a transverse second pivot shaft, at least one inclined guide face matched with the corresponding push rod is arranged on each second edge folding plate, and the guide faces can be pushed by the push rods to enable the second edge folding plates to rotate around the second pivot shafts. The edge folding mechanism is simple in structure; only one set of driving mechanism is needed for conveniently completing overturning of lateral faces and top folded edges of a filtering net at the same time, and the manufacturing cost of the device can be effectively reduced; meanwhile, the production time is shortened, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to filter net processing equipment, in particular to an edge folding mechanism. Background technique [0002] The folding of the filter screen usually needs to wrap the upper, lower and side surfaces of the filter screen edge. At present, the hard paper wrapping of the filter screen is usually made manually, which has low efficiency and high labor costs. A small number of manufacturers have begun to use folding machines for folding. However, since the traditional folding mechanism can only fold one side, these folding machines need to be equipped with two sets of folding mechanisms, one vertical and one horizontal, and correspondingly equipped. Two sets of driving mechanisms for driving the push rod to advance, and because the vertical and horizontal turning actions are required in sequence, a corresponding control device or delay device is required, which prolongs the production time, high equipment cost, and low production effic...
