Twin coil book-binding machine

Abstract

A double-coil binder for binding loose-leaf pages. Including frame, double-coil reel, double-coil output device, cutting mechanism, feeding mechanism, pressure ring mechanism, finished product output device, and automatic control device; said double-coil output device is composed of double-roller paper feeding mechanism It is composed of two parts of the double-coil transmission mechanism, in which the double-coil transmission mechanism is two sets of conveyor belts, driven by a stepping motor, and one set of conveyor belt pulleys has a tapered cross-section, thin edges, thick middle, and the thickness is close to Arc-shaped transition; said cutting mechanism includes conveying guide rails, dials, and cutters; wherein the teeth of the dials are arranged in regular intervals without equidistant arrangement; in the whole process of binding, the present invention in addition to threading the coils into The loose-leaf hole needs to be completed manually, and the rest are automatically completed by the machine, and the operation is convenient and the action is accurate, which can save a lot of labor and greatly improve the labor productivity.

Description

technical field [0001] The invention relates to the technical field of binding, in particular to a machine for binding loose-leaf pages with double coils. Background technique [0002] Double coils are used for binding loose-leaf pages. The shape of double coils is a continuous double-line "C" shape connected by a single line, but the back of the "C" has a slight concave, which is also like a reverse "3" shape. The following Briefly described as a "C" shape; when in use, put the "C" end of the coil into the preset hole on the loose-leaf book and close it. At this time, the coil forms a continuous "O" shape, and the loose-leaf book can be freely Turning pages is safe, reliable, and elegant; currently there is a special machine for pressing double coils into an "O" shape, but it is limited to aligning the double coils that have been cut to the required length with the preset holes in the loose-leaf It is only pressurized into an "O" shape; because there are various specificat...

[0002] Double coils are used for binding loose-leaf pages. The shape of double coils is a continuous double-line "C" shape connected by a single line, but the back of the "C" has a slight concave, which is also like a reverse "3" shape. The following Briefly described as a "C" shape; when in use, put the "C" end of the coil into the preset hole on the loose-leaf book and close it. At this time, the coil forms a continuous "O" shape, and the loose-leaf book can be freely Turning pages is safe, reliable, and elegant; currently there is a special machine for pressing double coils into an "O" shape, but it is limited to aligning the double coils that have been cut to the required length with the preset holes in the loose-leaf It is only pressurized into an "O" shape; because there are various specifications of double coils, such as 7 specifications commonly used for 3:1 coils, and 5 specifications commonly used for 2:1 coils; so many specifications double Coil, coupled with its flexible characteristics, how to transport the rolled double coil in place, how to cut it according to the required length, until the loose-leaf is bound into a book, there is no disclosure of this aspect in the search literature
