Abstract

The invention relates to devices for applying glue and can be used in mechanical engineering, woodworking industry, etc. The purpose of the invention is to improve the quality of gluing by ensuring the stability of the temperature - heating the melt glue to the area of its application. For this, the glue-making roller is made in the form of a hollow disk and is equipped with a heat stabilizer. The heat stabilizer is made in the form of an electrically insulating sleeve with a groove on its outer surface adjacent to the inner surface of the disk. The heating element is located in the annular channel of the heat stabilizer. 5 il.

The invention relates to devices for applying adhesives and can be used in mechanical engineering, the woodworking industry and other industries.

The purpose of the invention is to improve the quality of gluing by ensuring the stability of the temperature of heating the melt adhesive in the area of its application.

Figure 1 shows the proposed device on the stand, side view; figure 2 - the same, in the desktop version; on fig.Z - the device, front view; figure 4 is a device, side view; figure 5 is a device, top view.

The melt adhesive application device has two versions: the first is on the stand, the second is desktop (in the workplace).

It consists of a stand, a control cabinet 2, a protective casing 3, a hood 4, a control panel 5, a chamber 6 for preparing melt glue.

The chamber 6 is divided by a wall 7 into two parts: a loading and a consumable one, and in the lower part of the wall 7 there is a slit for the flow of liquid glue.

Chamber 6 is heated by heating elements 8 located under the bottom and on the side walls. Dp of increasing the heat exchange surface and accelerating the process of melting the glue inside the loading part of chamber 6 are welded by ribs 9.

Bearing supports 10 are fixed to the housing of the chamber 6, in which the adhesive roller 11, which is rigidly mounted on the shaft, rotates.

Inside the roller there is an electrically insulating sleeve 12, on the outer surface of which an annular channel is made with a heating element 13 laid in it. The output ends of the heating element .13 are attached to this connector, which includes both the collector 14 and the current collector 15. Rotation of the roller 11 is driven by a drive 16 A metering cleaning device is fixed on the body of the chamber 6, consisting of the metering knife 17 and two side cleaning knives 18. The chamber unit 6 with the roller 11 is freely placed in the heat-insulating casing 19. 16, consisting of a motor and gear unit.

through a belt drive 20 and a pair of interchangeable gears 21 is connected to a spreading roller 11. Chamber 6 has a neck 22, closed by a folding hatch 23, which is faced with a wooden panel.

The device works as follows.

The melt of glue in the form of granules through the neck 22 is loaded into the chamber 6, where it melts and flows through the gap in the wall 7 into the expendable part.

The temperature of the glue is monitored by a sensor (not shown) and when the setpoint value is reached, the system of heat and electrical automation permits the activation of the drive 16 for the rotation of the applicator roller 11.

The glue-applying roller 11, which is heated to a predetermined temperature, captures with its working surface the adhesive, the layer thickness of which is metered by the movable knife 17, and the excess is removed from the side surfaces by the knives 18 and brings it to the working area where it is applied to the product (for example, on the interface gasket) by briefly pressing it against the outer surface of the roller 11.

The use of a heat stabilizer in the device ensures the constant temperature of the process of applying the melt adhesive to the product, reduces power consumption by reducing heat loss, and reduces the melt consumption of the adhesive due to the constant viscosity and thickness of the layer on the roller surface.
