Production line of hot-melt pressure-sensitive adhesive

Abstract

The invention provides a production line of hot-melt pressure-sensitive adhesive, is intended to solve the technical problem that a heating mechanism of an existing production line has poor temperature control effect, affecting adhesive quality, and can ensure that temperature of adhesive in a reactor is relatively constant, avoid glue charring and ensure adhesive quality. The production line of hot-melt pressure-sensitive adhesive comprises a glue making reactor, a heating mechanism and a control mechanism; the control mechanism includes a controller and a temperature probe; a circulating pump, a heater and the temperature probe are electrically connected with the controller. The production line is characterized in that the heating mechanism also includes a three-way valve, the feed end of the three-way valve is connected with the discharge end of the circulating pump, one discharge end of the three-way valve is connected with the feed end of a coil, the other discharge end of the three-way valve and the discharge end of the coil are connected with the reflow end of a heat transfer oil storage tank; the discharge end of the heat transfer oil storage tank is connected with the feedend of the circulating pump, the three-way valve is in electronic control connection with the controller, and openness of the two discharge ends is adjusted through the controller.

Description

technical field [0001] The invention relates to the field of hot-melt pressure-sensitive adhesive production equipment, in particular to a hot-melt pressure-sensitive adhesive production line matched with a coating machine. Background technique [0002] The hot-melt pressure-sensitive adhesive used by the coating machine includes finished glue and ready-made glue. The ready-made glue is generally prepared and filtered through the hot-melt pressure-sensitive adhesive production line. For hot-melt pressure-sensitive adhesives required for beverage wrapping paper and similar products, it is necessary to ensure that the glue is free of impurities and air bubbles to avoid affecting the appearance of the wrapping paper after sticking. The existing hot-melt pressure-sensitive adhesive production line mainly includes a glue-making reaction kettle, a heating mechanism, a glue-feeding mechanism and a control mechanism. The glue-making reaction kettle is used to stir and mix the glue, ...
