Embodiment 1

[0046] EVA glue and PUR glue universal binding machine assembly has a bracket seat 42, a milling cutter 67 is installed in the milling cutter table body 63 on the left part above the bracket seat, and a guide is fixed on both sides of the front and rear parts of the milling cutter table body. Block 65, front cover plate 62 is installed between the two guide blocks of the front portion, and rear cover plate 68 is installed between the two guide blocks of the rear portion, front guide wheel 66 is connected on the front cover plate, and the rear cover plate is connected with Rear guide wheel 69, respectively is connected with extension spring 64 between described front and back cover plate and milling cutter table body, is connected with wallboard support 44 on the bracket seat, and pivoting axle sleeve 43 is installed on the wallboard support, and this pivoting axle sleeve The upper pivot is connected with a front wallboard 47 and a rear wallboard 45, and the corresponding place ...

Embodiment 2

[0061] The difference from the above example is that this example uses a three-way pipe to replace the connecting block of the above example. There is a three-way pipe under the rubber storage cylinder. One end is in communication with the glue outlet of the right cylinder, and the other end of the three-way pipe is connected with the glue outlet pipe 40 . Other constructions are the same as the above example.

Embodiment 3

[0063] see Figure 13 The difference from Example 1 is that there is no connection block in this example, and the corresponding large cylinder glue outlet 73 and the right cylinder glue outlet 74 are each connected with a rubber outlet pipe, which are respectively connected to the connecting flange 23 and the glue spray pipeline. Check valve 24. Other structures are the same as in Example 1.

Abstract

The invention provides a glue binding assembly universal for ethylene vinyl acetate (EVA) glue and polyurethane rubber (PUR) glue. A large glue cylinder, a right small glue cylinder and a left small glue cylinder are arranged in a glue storage cylinder. Glue outlets are formed in the bottom of the large glue cylinder and the bottom of the right small glue cylinder correspondingly. The two glue outlets communicate with each other and are combined at a main glue outlet. An air inlet and an air outlet are formed in the upper portion of the large glue cylinder. A glue spray seat is provided with a glue spray pipeline and a glue spray port. The glue spray port communicates with the glue spray pipeline. The glue spray pipeline communicates with the main glue outlet. Guiding planes are arranged on the front portion and the rear portion of the glue spray seat correspondingly. A front glue baffle and a rear glue baffle are buckled the two guiding planes correspondingly. Side glue spray nozzles are formed in the front glue baffle and the rear glue baffle. A double-end lead screw is installed between a front wall board and a rear wall board in a straddling mode. A right thread sleeve and a left thread sleeve of the double-end lead screw are each connected with a driving pin. A front driving plate and a rear driving plate are connected to the left side of the front glue baffle and the left side of the rear glue baffle correspondingly. The driving pins are inserted into a backing pin part of the front driving plate and a backing pin part of the rear driving plate correspondingly. A reset tension spring is connected between the front driving plate and the rear driving plate. The glue binding assembly is used for threadless book glue binding.

Description

technical field [0001] The invention relates to a structural part of a small linear wireless glue binding machine, especially a glue spreading device. Background technique [0002] The small linear wireless glue binding machine is a kind of equipment that applies hot melt glue on the spine side of the book block to glue the books. Glue binding machines generally use EVA hot melt adhesive and PUR hot melt adhesive. EVA hot melt adhesive is a common hot melt adhesive with low cost. After heating and melting, the glue is completely cured after 24 hours and can be heated and melted again; EVA hot melt adhesive is generally used in open plastic boxes, and the books after glue binding cannot be 180° open. PUR (Polyurethane Reactive active polyurethane) hot-melt adhesive has a high cost, but it has excellent bonding strength and excellent temperature resistance, chemical resistance, corrosion resistance, and aging resistance. The adhesive layer of glue-bound books is thin and fle...
