Structure, the reflux mechanism connection glue feed mechanism and plastic emitting mechanism, with when plastic emitting pressure within the organization is more than threshold values, glue can be with
Flow back into glue feed mechanism.
10. a kind of glue-pouring method, which is characterized in that include the following steps：
Step S 1：Set the plastic emitting total amount in the unit interval of plastic emitting ratio and glue feed mechanism；
Step S 2：Practical gel quantity is measured, the practical gel quantity of glue feed mechanism is measured by glue amount metrological service；
Step S 3：Judge whether gluing mechanism needs glue amount to compensate, control mechanism is by the setting gel quantity and reality of glue feed mechanism
Gel quantity compares, and judges to set with the presence or absence of difference between gel quantity and practical gel quantity, be given birth to using difference if there are difference
At glue amount compensated information, the gel quantity of feedback control glue feed mechanism, to compensate the gel quantity next time of glue feed mechanism.
