Integrated envelope eyelet binding machine

Abstract

The invention relates to the field of envelope binding equipment, in particular to an integrated envelope eyelet binding machine. The integrated envelope eyelet binding machine comprises a rack, an envelope feeding device, an envelope tongue opening position pressing and buckling device, a rope threading device, an envelope front face position pressing and buckling device and a finished product output device are arranged on the rack in sequence, the rope threading device is located below the envelope tongue opening position pressing and buckling device, the envelope tongue opening position pressing and buckling device and the envelope front face position pressing and buckling device are same in structure, the envelope front face position pressing and buckling device comprises a punching mechanism, a feeding roller, an inserting hole device, a pressing and buckling device and an air suction device which are mounted on the rack in sequence, according to the integrated envelope eyelet binding machine, punching, rivet putting and envelope nailing integration of a strip blank material can be achieved, error accumulation caused by in-advance punching can be avoided, the nailing error canbe prevented, work efficiency is improved, through a punching mechanism, the strip blank is punched, punching precision is improved, it is ensured that the hole inner wall is free of burrs, failuresof the envelope eyelet binding machine are avoided, and the binding quality of envelopes can be improved.

Description

technical field [0001] The invention relates to the field of envelope binding equipment, in particular to an integrated envelope eye button binding machine. Background technique [0002] In the existing envelope binding process, it is necessary to punch holes in the strip-shaped blank material for making eye buttons in advance, then put the rivets into the punched holes, and then press the rivets and strips together to buckle the envelope. In fact, this will gradually accumulate the positioning errors between the rivet placing station and the strip-shaped blank for punching holes, which will easily lead to large nailing errors, resulting in failure of the envelope eye button binding, reducing the binding quality of the envelope, and requiring multiple times. Calibrating the punching mechanism is time-consuming and labor-intensive, which reduces work efficiency. When punching strip-shaped blanks, the waste will easily block the puncher, and the inner wall of the punching hole...

[0002] In the existing envelope binding process, it is necessary to punch holes in the strip-shaped blank material for making eye buttons in advance, then put the rivets into the punched holes, and then press the rivets and strips together to buckle the envelope. In fact, this will gradually accumulate the positioning errors between the rivet placing station and the strip-shaped blank for punching holes, which will easily lead to large nailing errors, resulting in failure of the envelope eye button binding, reducing the binding quality of the envelope, and requiring multiple times. Calibrating the punching mechanism is time-consuming and labor-intensive, which reduces work efficiency. When punching strip-shaped blanks, the waste will easily block the puncher, and the inner wall of the punching hole is not smooth enough to facilitate the smooth insertion of rivets, resulting in punching Poor quality and low yield rate, in view of this, we propose an integrated envelope eye button binding machine
