Problems solved by technology

The glue wire heating device with the above structure has the following disadvantages: 1) The front end of the central tube of the heating head connected to the glue wire heater is heated relatively, while the rear end is heated less, so the glue wire is heated unevenly in the central tube of the heating head , when splicing wood chips, the glue line will break away intermittently at the seam, so that the wood chips after splicing cannot meet the quality requirements; Defect of filament clogged nozzle

Abstract

The invention is the glue thread heating equipment of a tooth glue single-board longitudinal splicing machine, which comprise the nozzle, the heatheat central tube, the glue thread heater. It is characterized in that the central tube heater directly connects the heathead central tube; the inner chamber of the central tube connects the inner chamber of the central heater. The inner wall of the nozzle is coated a layer of Teflon, and the central tube connects the central heater. The temperature of the whole heathead central tube is the same, and the relatively high temperature ensures the heat melting state of the glue threads equal and consistent; the Teflon material of the nozzle does not have affinity with the heat melt of the glue threads. The air conditioning tube ensures the fast decreasing of the temperature of the central tube and the nozzle when machine stopping so as to solidify the melted glue threads and unblocking of the nozzle.

Description

technical field [0001] The invention relates to the technical field of woodworking machinery, in particular to a glue line heating device of a woodworking glue line splicing machine. Background technique [0002] China utility model patent number: ZL03224244.1, the name is "toothed glue line veneer longitudinal splicing machine", its authorized announcement number: CN2602892Y, authorized announcement date: February 11, 2004; the splicing machine discloses a glue The wire heating part, its structure includes the nozzle, the central tube of the heating head and the glue wire heater. The inner cavity of the heater is connected; when working, the glue line heater heats the air and is blown into the inner cavity of the central tube of the heating head, so that the glue line in the central tube of the heating head is heated and softened, and finally the softened glue line is sprayed out by the nozzle , glue the wooden blocks together. The glue wire heating device with the above ...
