Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of printing equipment, and specifically relates to a full-automatic printing collating and gluing nozzle. BACKGROUND

[0002] Gluing, also known as wireless gluing, refers to a binding method for fixing each page of a printed matter on the spine by using glue. It coats hot melt glue at the spine, then sticks the pages together, and finally adds a cover to form a complete printed matter. This binding method does not need to use iron wire or thread to sew the pages like traditional saddle binding or thread binding, so that the appearance of the book can be more flat and beautiful. The glue coating nozzle used in gluing utilizes the inverse piezoelectric effect of piezoelectric material. When a voltage is applied, the piezoelectric material will deform, thereby accurately controlling the opening and closing of the nozzle and the spraying of glue. However, in actual use, the existing glue coating nozzle cannot adjust the orientation angle and cannot adapt to the gluing requirements at different positions of the pages.

[0003] In order to solve the problems existing in the prior art, people have carried out long-term exploration and put forward various kinds of solutions.

DETAILED DESCRIPTION

[0023] The utility model will be further explained in detail in connection with the drawings and specific embodiment.

[0024] As Figures 1-5 shown, a full-automatic printing page gluing nozzle, including the adapter head 1 that is cylindrical and is connected with glue supply system, the adapter head 1 is usually arranged vertically downward. Wherein the first steering part 2 is rotatably installed at the end of adapter head 1, the second steering part 3 is rotatably installed at the end of first steering part 2, and the steering driving assembly 4 that independently drives is arranged between adapter head 1 and first steering part 2 and between first steering part 2 and second steering part 3. The steering driving assembly 4 provides the rotating driving force for the first steering part 2 and the second steering part 3, has two degrees of freedom, and can realize the flexible movement of the end of second steering part 3 in the hemispherical region.

[0025] Specifically, in order to ensure the rotation flexibility, the first adapter sleeve 11 is fixed at the end of the adapter 1, and the central axis of the first adapter sleeve 11 is inclined relative to the central axis of the adapter 1. The second adapter sleeve 12 is arranged at the end of the first steering part 2 and is in rotation connection with the first adapter sleeve 11. The central axis of the second adapter sleeve 12 is inclined relative to the central axis of the adapter 1. When the first adapter sleeve 11 and the second adapter sleeve 12 rotate relative to each other, the relative angle between the central axis of the adapter 1 and the central axis of the first steering part 2 changes.

[0026] Further, the steering driving assembly 4 includes a first driving motor 41 fixed on the adapter 1. The first driving motor 41 is a micro motor. A first driving gear 42 is fixed at the output end of the first driving motor 41. A first driving gear ring 43 is arranged at the end of the first steering part 2 and is in meshing transmission with the first driving gear 42. The first driving motor 41 drives the first driving gear 42 and the first driving gear ring 43 to mesh and transmit. The adapter 1 is usually provided with additional driving structure to realize self-rotation.

[0027] Further, in order to further increase the adjustment range of the nozzle 7, a third adapter sleeve 21 is fixed at the end of the first steering part 2, and the central axis of the third adapter sleeve 21 is inclined relative to the central axis of the first steering part 2. A fourth adapter sleeve 22 is arranged at the end of the second steering part 3 and is in rotation connection with the third adapter sleeve 21. The central axis of the fourth adapter sleeve 22 is inclined relative to the central axis of the third adapter sleeve 21.

[0028] Further, similar to the structure of the steering driving assembly 4 described above, the steering driving assembly 4 further includes a second driving motor 44 fixed on the first steering part 2. A second driving gear 45 is fixed at the output end of the second driving motor 44. A second driving gear ring 46 is arranged at the end of the second steering part 3 and is in meshing transmission with the second driving gear 45. The second driving motor 44 is independently driven and controlled with the first driving motor 41. The driving speed and the rotation angle thereof are flexibly adjusted through a main control unit.

[0029] In addition, a plurality of fixed seats 5 arranged in a central symmetry are arranged on the outer side of the adapter 1 to facilitate assembly with the gluing production line. Threaded holes 51 are formed in the fixed seats 5 for inserting threaded members. An inlet pipe 52 is connected to the inner side of the adapter 1. The inlet pipe 52 is used to guide the printing glue.

[0030] At the same time, in order to prevent external foreign matters from invading, the adapter 1, the first steering part 2 and the second steering part 3 are covered with a protective cover 6. Flexible protective sleeves 61 are arranged at the joints of the adapter 1, the first steering part 2 and the second steering part 3 to not affect the normal activities. The protective cover 6 is preferably made of aluminum alloy.

[0031] As can be seen, a nozzle 7 made of stainless steel is arranged at the end of the second steering part 3. The nozzle 7 is conical and internally provided with an extrusion cavity 71. The nozzle 7 usually adopts a modular structure. The caliber specification inside the nozzle 7 is selected according to actual needs.

[0032] It is obvious that in order to meet the requirement of free movement of the nozzle, a transmission hose 8, preferably a metal bellows, is arranged between the inside of the adapter 1, the first turning part 2 and the second turning part 3, taking into account the structural strength and bending flexibility.

[0033] Preferably, the adapter 1 is equipped with a piezoelectric sensor, which, when the adapter 1 is pressed down as a whole, contacts and senses at the end of the second turning part 3, thereby sending a sensing signal to make the glue supply system spray glue.

[0034] In summary, the principle of the present embodiment is that the adapter 1 drives the first turning part 2 and the second turning part 3 to deflect independently through the turning drive assembly 4, thereby adjusting the orientation of the nozzle 7 at the end of the second turning part 3.

[0035] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.

[0036] Although the terms adapter 1, first adapter cylinder 11, second adapter cylinder 12, first turning part 2, third adapter cylinder 21, fourth adapter cylinder 22, second turning part 3, turning drive assembly 4, first drive motor 41, first drive gear 42, first drive gear ring 43, second drive motor 44, second drive gear 45, second drive gear ring 46, fixed seat 5, fixed hole 51, glue inlet pipe 52, protective cover 6, flexible protective sleeve 61, nozzle 7, extrusion cavity 71, transmission hose 8, etc. are used more frequently herein, the possibility of using other terms is not excluded.
