Problems solved by technology

The glue line heating device with the above structure has the following disadvantages: since the nozzle is made of metal material, the glue thread is easy to block the nozzle when the glue thread is in a hot-melt state. High, the hot melt state of the glue is not easy to solidify, and it is easy to block the nozzle

Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , as shown in Figure 2, a glue line heating device for a toothed glue line veneer longitudinal splicing machine, including a nozzle 3, a heating head center tube 4, and a glue line heater 1, the glue line heater 1 is made of a stainless steel tube shell, as The heat pipe is composed of an insulating tube and a spiral heating wire. The glue wire heater 1 is connected to the central tube 4 of the heating head. There is a central tube heater 2 for heating the central tube 4 of the heating head. The inner wall of the central tube 4 is lined with a layer of high-temperature-resistant polytetrafluoroethylene. The inner cavity of the central tube heater 2 communicates with the inner cavity of the central tube 4 of the heating head. The central tube heater 2 is composed of a heating wire 21 and an insulating layer 22. , stai...

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] 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 wood blocks together. The glue line heating device with the above st...
