Glue spraying mechanism of perfect adhesive binding machine

Abstract

The invention discloses a glue spraying mechanism of a perfect adhesive binding machine, which comprises a glue applicator center plate and a glue tank arranged on the glue applicator center plate, wherein the glue applicator center plate is provided with a first glue outlet and a second glue outlet; a seal cover is covered on the second glue outlet; the port of the first glue outlet is provided with an outer glue spraying tube, the upper part of the outer glue spraying tube is provided with an outer glue spraying groove, an inner glue spraying tube is sleeved in the outer glue spraying tube, the inner glue spraying tube is provided with an inner glue spraying groove, and the inner glue spraying tube is communicated with the glue tank through the first glue outlet; and an adjusting slide block is sleeved on the outer glue spraying tube, an adjusting screw rod is screwed on the adjusting slide block, the other end of the adjusting screw rod is arranged on a support plate, the end part of the adjusting screw rod is provided with a first bevel gear, and the first bevel gear is engaged with a second bevel gear arranged on a motor decelerator. The mechanism saves materials, sprays glue uniformly, has no glue waste and quite firm paper bonding degree, and is quite simple for daily cleaning and maintenance.

Description

technical field [0001] The invention relates to a gluing device for perfect binding after printing, in particular to a glue spraying mechanism for a wireless perfect binding machine that uses PUR glue for perfect binding of books, which can meet the needs of coated paper and some printed matters with high quality requirements for perfect binding. Perfect binding required. Background technique [0002] At present, the gluing device of the general-purpose perfect binding machine on the market often adopts a roller gluing mechanism, and what is generally used is a hot-melt glue. The gluing of this mechanism is not uniform, and it is easy to produce air bubbles, which affects the quality of the perfect binding, and has a large amount of waste, has a pungent smell, pollutes the environment, and is also very troublesome for daily cleaning. Contents of the invention [0003] The purpose of this invention is to design a glue spraying mechanism of a wireless perfect binder. [00...
