Detailed description of the invention
Electric heating constant temperature low-pressure melt adhesive bucket, including gum exudation mouth (5), side neck (7), bung (11);Bung (11) covers and seals in side neck upper port.Also include electric heating base plate (1);Electric heating bottom panel side is opened electrothermal tube and is inserted hole (15), and electrothermal tube inserts hole and is inserted into electrothermal tube.Electric heating base plate (1) is connected together with side neck lower port seal weld;Electric heating backplate surface array heat conductive bar (19).Heat conductive bar (19) is positioned at side neck (7).Electric heating base plate (1) central authorities open melten gel pond (23), and melten gel pond (23) upper cover net leakage (17), melten gel pond (23) are connected with gum exudation mouth (5) by electric heating base plate endoporus (21);Side neck upper bands air inlet and air vent (13).Bung corner is locked with side neck upper port by four lifting bolts (9) respectively, makes lid respectively be sealed to uniform force with side neck upper port by sealing ring.Side neck outer surface is wound around heat tape, then outsourcing adiabator layer covers.This structure, reduces external heat radiation, but to side neck inner shaft asymmetric conduction heat.By the electric current of electrothermal tube and heat tape all by thermostatic control system control.Electrothermal tube array distribution, the power of every electrothermal tube is less, and in thermostatic control, thermal inertia is little.Heat tape is all over twining side neck outer surface, and uniformly, temperature control is accurate, and thermal inertia is the least in heating everywhere.
During work, gum exudation mouth connects glue spraying head by pipeline, and air inlet and air vent are respectively connected to the pipeline of pressure air.Open bung, add solid-state glue and close again bung.Electrothermal tube, heat tape and temperature control system power on.When temperature control reaches 240 degrees Celsius, 3 kilograms of pressure airs can be filled with in bucket.Now, gum exudation mouth can flow out the liquid glue of certain flow rate and flow.In bucket, melten gel process is: solid-state glue falls into and directly contacts with heating rod and electric heating base plate between array applicator rod.Electrothermal tube heats, and electric heating base plate and heat conductive bar temperature rise, and relies on heat transfer directly the temperature of solid-state glue to be promoted.When temperature is increased to the fusing point of glue, solid-state glue i.e. starts to melt.The liquid glue melted sinks to bottom, leaks through filter through net, flows in melten gel pond.Solid-state glue falls into bottom and melts in the liquid glue, and accelerates a barrel melting for internal solid glue.Temperature control system can maintain melting temperature, until solid-state glue all melts.In glue spraying operation, can empty bucket when liquid glue is not enough in, pressure air opens bung addition solid-state glue, and close bung charged pressure air immediately.Add solid-state glue process short, do not affect being carried out continuously of glue spraying operation.
