Glue line heating device of zigzag veneer longitudinal splicer

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 nozzle is made from Teflon, the internal layer of the central tube is coated with Teflon, and the central tube connects the central heater and the air conditioning tube. 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] At present, in the glue thread heating device in the prior art, the glue thread is heated unevenly in the central tube of the heating head. When splicing wood chips, the glue thread will break away intermittently at the seam, so that the quality of the wood chips after splicing is not up to standard. It is required that the nozzle is made of metal material. When the glue thread is hot-melt and liquid, the glue thread is easy to block the nozzle. When the splicing machine is shut down, the temperature in the center tube of the heating head and the nozzle is still high, and the hot-melt state of the glue thread is not easy to solidify. Contents of the invention [0003] The object of the present invention is to provide a glue thread heating device for a tooth-shaped...
