Abstract

The invention discloses a high-precision hot melt glue nozzle. The high-precision hot melt glue nozzle is mounted on a glue gun body; the glue gun body is provided with a solution supply channel and a gas supply channel; the high-precision hot melt glue nozzle comprises a nozzle body and a core body, wherein a containing hole penetrating the upper and lower parts of the nozzle body is formed inside the nozzle body; the core body is matched with the containing hole and is closely embedded in the containing hole; a glue solution channel with an opening in the lower end surface of the core body is formed inside the core body; at least two gas channels extending to the lower end surface of the core body are formed in the peripheral surface of the core body; a gas channel is formed between the gas channel and the wall of the containing hole. The glue solution channel and the solution supply channel are communicated for outputting an glue solution line during operation, the gas channel and the gas supply channel are communicated for outputting gas flow, the glue solution line is output in a specific shape under the action of the gas flow, and the machining of the gas channel can adopt a mode of milling a groove in the conical peripheral surface of the core body to replace the traditional drilling mode, so that the formation mode of the gas channel is more accurate and efficient than the traditional drilling technology.

Description

technical field [0001] The invention relates to a hot melt glue nozzle and a hot melt glue gun. Background technique [0002] As known, a gas channel and a glue channel are formed in the hot melt glue nozzle. During operation, the glue channel outputs the glue line, and the gas channel outputs the air flow, and the trajectory of the glue line is changed by the air flow, such as the spiral arrangement in the glue channel The gas channel on the outer periphery can output spiral air flow to make the glue liquid line output in a spiral shape, and the inclined gas channel arranged symmetrically on both sides of the glue liquid channel can output cross air flow to make the glue liquid line output in a wave shape. Therefore, The arrangement and inclination angle of the gas channel require high-precision processing. The traditional process is to use drilling equipment to process the gas channel on the nozzle, and adjust the feed angle of the drill bit to process the gas channel with...

[0002] As known, a gas channel and a glue channel are formed in the hot melt glue nozzle. During operation, the glue channel outputs the glue line, and the gas channel outputs the air flow, and the trajectory of the glue line is changed by the air flow, such as the spiral arrangement in the glue channel The gas channel on the outer periphery can output spiral air flow to make the glue liquid line output in a spiral shape, and the inclined gas channel arranged symmetrically on both sides of the glue liquid channel can output cross air flow to make the glue liquid line output in a wave shape. Therefore, The arrangement and inclination angle of the gas channel require high-precision processing. The traditional process is to use drilling equipment to process the gas channel on the nozzle, and adjust the feed angle of the drill bit to process the gas channel with different inclination angles and arrangements. This processing method There are many uncertain factors, which can easily cause inaccurate angles. For example, the drill bit is in the middle of the drilling hole, because it is relatively thin, it is easy to break or drill off.
