Description

Pneumatic cold-gluing book equipment

Technical Field

The utility model relates to a wireless mucilage binding equipment of books, especially a pneumatic type cold glue glues book equipment.

Background

A conventional wireless glue binding machine, as shown in fig. 20, mainly comprising a frame, a page bundle clamping mechanism 1 disposed on the frame, a milling cutter mechanism 3 for milling a gap groove on the lower side (also called book back) of a page bundle 2 disposed in front of the page bundle clamping mechanism 1, a glue applying mechanism for applying a back glue to the lower side of the page bundle 2 and applying side glues to both sides of the lower end of the page bundle 2, a cover mounting mechanism disposed in front of the milling cutter mechanism 3, and a control device for controlling the above mechanisms, wherein the glue applying mechanism comprises a glue groove 4, a back glue wheel 5 and a side glue wheel 6, the page bundle clamping mechanism 1 clamps loose leaves to be bound into the page bundle 2, the side glue wheel 6 applies EVA hot melt glue in the glue groove 4 to both sides of the lower end of the page bundle 2 to form a side glue layer, the side glue layer is commonly called side glue, and when the loose glue passes through the circumference of the back glue wheel 5, the back glue wheel 5 applies EVA hot melt glue in the glue groove 4 to the lower side of the page bundle 2, forming a bottom glue layer, commonly called as gum, and controlling the distance between the lower side of the page stack 2 and the gum wheel 5 by adjusting the height of the reference platform 101 of the page stack clamping mechanism 1, thereby controlling the coating thickness of the gum, and finally transferring the page stack 2 coated with the gum and the side gum to a cover mounting mechanism for cover binding, and finally finishing the binding of books or texts. The existing traditional hot melt adhesive binding technology has qualitative leap compared with the original manual glue brushing binding, so that the book binding quality is greatly improved, but the traditional hot melt adhesive binding technology also has the following defects which cannot be overcome: 1. because the glue groove is open, the hot melt adhesive in the glue groove is continuously volatilized, so that the glue solution is wasted, and the working environment is polluted; 2. the hot melt adhesive in the adhesive tank is repeatedly subjected to the processes of heating, cooling and carbonizing, is a regenerated adhesive solution forever, and can be repeatedly used, so that the bonding performance of the hot melt adhesive can be greatly reduced; 3. when the machine is started for use, the solidified hot melt adhesive is completely melted and then can be applied, the glue melting time is long, and the glue temperature is not easy to control; 4. the hot melt adhesive is coated to the lower side of the page stack through the adhesive wheel, the adhesion between the hot melt adhesive and paper fibers is not sufficient due to no pressure during coating, even if the milling cutter mechanism slots the lower side of the page stack, the hot melt adhesive can be properly extruded into the slot, but the adhesion between the hot melt adhesive and the paper fibers is not sufficient due to small pressure, and the phenomena of page falling, book back cracking and the like often occur when thick books and art paper books are wrapped; 5. because the side glue is formed by extruding the side glue wheel, the thickness of the glue layer is uneven, and the height of the edge is uneven, thereby affecting the glue binding quality of the front cover.

The invention patent with the publication number of CN102815110B (patent number of ZL 201210331536.2) discloses a glue-spraying type wireless glue binding machine, which greatly improves the defects of the glue binding machine. The invention mainly comprises a frame 01, a page stack clamping mechanism 1 arranged on the frame 01, a milling cutter mechanism 3 for milling a gap groove on the lower side (namely a book back) of a page stack 2, a glue applying mechanism, a cover mounting mechanism and a control device for controlling the actions of the mechanisms. The glue tank replaces a glue tank in the prior art, the hot melt glue is heated in the glue tank in a sealed state, the defects that the hot melt glue in the glue tank is continuously volatilized and pollutes the working environment are overcome, the molten glue solution is pressed into a nozzle through a glue delivery pipe through a glue outlet at the bottom of the glue tank under the action of pressure, and by the structure, the glue melting time is short, and the defects that the hot melt glue in the glue tank in the prior art is repeatedly heated, cooled and carbonized are overcome; the spraying has enough pressure, the glue solution is fully bonded with the paper fiber, the bonding performance is good, the binding quality is high, when thick books and art paper books are bound, the phenomena of page dropping, book back cracking and the like can not occur, and the binding quality of the front cover is greatly improved. However, in the course of extensive use, the above technical solution we have found that it still has disadvantages: 1. because the hot melt adhesive is used as a binder, electric energy is consumed for melting, the time for dissolving the adhesive is as short as 30 minutes, and one hour is needed for more time, the adhesive can not be used when being started, the adhesive liquid is easy to age and deteriorate in the heat receiving capacity, so that an imperfect result is generated in use, and certain potential safety hazard exists; 2. the glue binding machine mainly depends on the motor to drive each mechanism to move, so the glue binding machine has larger volume, limited action speed and larger noise, and is not beneficial to placing in office places; 3. after the glue book is finished, the paper is not easy to flatten.
