an edge banding mechanism

Abstract

The invention relates to an edge sealing mechanism. The edge sealing mechanism comprises a rack, a conveying mechanism and a sealing assembly, wherein the conveying mechanism and the sealing assembly are arranged on the rack. The sealing assembly comprises a fixing base, a left installing base, a right installing base and an installing base drive mechanism. The fixing base is arranged on the rack in a sliding manner through a linear guiding mechanism and is in a U shape, and a through groove is formed in the middle of the fixing base. The left installing base and the right installing base are arranged on the fixing base in a sliding manner, and a clamping opening is formed between the left installing base and the right installing base. In a front-back projection face, the clamping opening is vertically arranged in the through groove of the fixing base, and an upper opening of the clamping opening is contained in an upper opening of the through groove. The sealing assembly is of a U-shaped structure, the upper end of the sealing assembly is not closed, and the film penetrating action can be conducted without other operation. The left installing base and the right installing base can move in parallel. Each installing base is provided with two or more force application points for push force transmitting, even force application of the installing bases during sealing is guaranteed, and therefore the high sealing quality can be achieved.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to an edge banding mechanism of a horizontal packaging machine. Background technique [0002] The edge banding mechanism is an important part of packaging machinery. Most of the existing edge banding mechanisms are "mouth" shaped structures. When the film is threaded, the button needs to be rotated to open the mechanism, and then closed after the film is threaded. The film threading operation is relatively complicated. And the sealing action is similar to the opening and closing of scissors, the left and right mounting seats move non-parallel, and the force applied to the sealed bag is uneven during sealing, resulting in poor sealing quality and appearance, and it needs to be adjusted when changing the size of the bag to achieve the best working condition; The mounting base is mostly connected by bolts, and the bolts are removed when replacement is needed; at the same ti...
