Description

2, the device according to claim 1, about-and l with the fact that, in order to align the pressure of the adhesive and create

wave uniform along the length of the slit, the cavities are made in the form of labyrinths of variable cross section.

 ,

The invention relates to technological equipment for the manufacture of glued structures and can be used in devices for applying glue to the ends of cells of soBeox fillers.

A device for coating sheet material is known, comprising a manifold with ports for supplying the coating material, pressure rollers, a housing with a cavity and an exit slot / tank and pumps with pipelines. The length of the slit in the body is equal to the width of the product. The coating material is pumped through the pipeline into the manifold and then through the nozzles into the body cavity. Sheet material is moved along the surface of the housing above the exit slit of the cavity. In this case, the material is impregnated with i 1

However, the design of the known device does not ensure uniformity of the coating material along the length of the slit due to a change in the wave height of the coating material along the length of the slit. In addition, when using the known device for applying a liquid coating material to the walls of the cell transfer. semi-fillers of different heights on the front and rear walls.

Closest to the invention to the technical essence and the achieved result is a device for applying glue to the ends of the cells. honeycomb aggregates containing a manifold with nozzles for supplying glue, a bath for collecting glue, a pressure roller and a housing with a cheek, forming between them a cavity with an exit slit. A grid is installed inside the casing to equalize the pressure and provide the same height of the glue wave along the entire length of the slit, equal to the width of the product 1.

. However, the known device does not provide an equal height for applying glue to the cell walls of the honeycomb filler along its width, since the glue wave along the slit length is variable in height: it is higher near the supply pipes, and between them - below, i.e. the lattice cannot completely equalize the pressure along the gap and, especially, at a great length.

the result is a low quality adhesive layer.

The purpose of the invention is to improve the quality of the adhesive layer and the

labor productivity.

The goal is achieved by the fact that in the device for applying glue to the cell ends of the honeycomb aggregates containing the collector - with branch pipes

for supplying glue j, a collection bath for glue, a pressure roller and a housing with a cheek, forming a cavity with an exit slit between them, the HOUSE is provided with an additional cheek, forming a cavity with an exit slit, and

the surfaces of the housing and the cheeks placed along its sides are made with exit slots and are inclined to the symmetry plane of the housing, while the cavities communicate with the collector through a channel made in the housing and holes

Moreover, to equalize the pressure of the glue and create a uniform wave along the length of the waves, the cavities are made in the form

maze variable cross section.

FIG. 1. schematically shows the proposed device, a common CCD, a partial section in FIG. 2 - section aa in figure 1} on fng. 3 - part of the processed product; and

A device for applying glue to the ends of cells of honeycomb fillers includes a collector 1 with nozzles 2 for supplying glue, a bath 3 for collecting glue

With pipe 4 for discharging glue, case 5 with end plates 6 and cheeks 7 attached to it. Plates 8 are installed on cheeks 7. Cheeks 7 and plates 8 form cavities with output slots 9 with body, the values of which are controlled by changing the position of plates 8 The cavities are embedded in a labyrinth of variable cross section. A pressure roller 10 is mounted above the housing 5, the pressure of which on the product is regulated by the load (not shown). At the same time, the surfaces of the body 5 forming the output surfaces and the cheeks 7 placed along its sides are {amp amp | 1 with a slope to the plane of symmetry

enclosures.

The housing 5 has a channel 1G and holes 12 through which the cavities communicate with the collector 1. Moreover, the lateral surfaces of corpus 5 and the inner surfaces of the cheeks 7 form -itu two cavities 13 I.14 interconnected by gaps 15. The holes 12, the cavities 13 and the slits 15 are intended to equalize the pressure along the entire length of each exit slit 9. The device operates as follows. The glue from the pumps of the two sides enters copLextf 1, then through nozzles 2 into channel 11 of housing 5. From channel 11 through openings 12 enters cavity 13, then through slot 15 into cavity 14 and through outlet slots 9 under Pressure flows ver into the form of a wolf from each slot, the length of the cozzroy is equal to the width of the cellular power supply 16. The supply of glue under the chant to the cavity 13 through the openings 12 creates pressure in it. However, the pressure in the opening, ty x 15 is greater than between them. The glue then passes through the slit 15 and enters the cavity 14, where its pressure is equalized by the PBX. From the output slots 9, the adhesive flows under the pressure of the entire length of each glue. The height of the waves is regulated by the throttles (not shown). After the glue bath is formed, an additional: (at the same height for glueing the cells of the honeycomb core 16 to a height H is moved. The honeycomb core under the action of the pressure roller 10 slides along the surface of the housing 5 through the glue bath. At the same time, the glue from the first original slot 9 is applied - to the rear cell steaks, and from the second output lens 9 to the front walls of the cells. The presence of the glue bath contributes to a more complete adhesive, and the wave height of the adhesive coming from the kg gap is adjusted by the plates 8. The presence of two is adjustable The slits, angled at the angle of the paths to the friend, and the adhesive bath formed between them, simultaneously apply hot glue at a given equal height to the front, sidewall and rear walls of the cells of the honeycomb core, thereby increasing the quality of adhesive application and the speed of movement of cellular aggregates. .. The expected economic effect from the use of money will be 6290 rubles per year.
