Improved book-binding machine handpiece

Abstract

The invention discloses an improved machine head of a binding machine, which belongs to the technical field of binding machinery and equipment. The invention aims to provide the improved machine head of the binding machine having the advantages of high binding quality, high binding speed and wide range of binding thickness. The improved machine head has the technical key points that a swinging block component consisting of a swinging block, a pressure arm, a pressure spring, a column and a spigot shaft is arranged between the lower part of an outer shell (1) of the machine head and a molding column (16); the swinging block (11) in the swinging block component is fixed on the outer shell of the machine head by taking the spigot shaft (2) as a rotating pair and is also adjacent to the left side of a striking block (10) on a hook sliding plate (5); the upper part of the pressure arm (13) is arranged in a guide slot of the swinging block and is also connected with the guide slot by a cylindrical pin to form the rotating pair; and the column (14) on the tail end of the pressure arm is inserted into a radial slot on the outer end surface of a forming column, and the pressure spring (12)is arranged between the upper end of the pressure arm and the swinging block. The improved machine head has the advantages of ensuring binding quality, improving binding speed, and making the bindingthickness reach the range between 0.2 and 15 mm.

Description

technical field [0001] The invention relates to an improved binding machine head, which belongs to the technical field of binding machinery and equipment. Background technique [0002] At present, the maximum binding thickness of various types of multi-head binding machines produced in China is only 4 millimeters. In the domestic binding machine head, because the part layout of the binding mechanism itself limits the adjustment of the feeding length and the length of the movement stroke, and the part layout is limited by the head shell, when binding books of different thicknesses, it is necessary to complete all During the binding process, it is necessary not only to adjust the binding head to ensure the normal operation of the machine head, but also to adjust the binding stroke of the machine, otherwise the head jamming or offside phenomenon will occur, resulting in damage to the machine head. That is to say the key of the size of the binding thickness range is the moveme...
