step 4: at the moment, the outer positioning hole (1023) and the inner positioning groove (1013) are in a communication state, the positioning insert block (11) is inserted into the communicated outer positioning hole (1023) and the inner positioning groove (1013), the movable outer sleeve (12) is influenced by the thrust of the spring (13) to move, the inner side of the movable outer sleeve (12) is contacted with the positioning insert block (11), and the positioning insert block (11) is fixed;

step 5: colloid enters the conveyor main body (1) through the feed inlet (1011), and when the motor (3) drives one of the spiral conveying rods (2) in the conveyor main body (1) to rotate through the synchronous belt (4), the spiral conveying rod (2) drives the other spiral conveying rod (2) to rotate in the opposite direction through the two pinions (5), so that the colloid conveying and mixing are realized;

step 6: the outside of the spiral conveying rod (2) is provided with an elastic coating to absorb a part of shearing force, so that the damage of a colloid molecular structure is prevented, and the colloid is finally discharged through a discharge hole (1021), so that the device using process of continuously producing the OCA glue is completed.
