Description
Technical Field
The invention belongs to the technical field of refrigerator foaming, and particularly relates to a device and a method for adjusting the position of a material injection gun head.
Background
The foaming of the refrigerator body is an essential important process in the process of manufacturing the refrigerator, generally speaking, a material injection port (generally a circular hole with the diameter of 36 mm) is arranged at the bottom of the refrigerator body or other positions, a material injection gun head (the outer diameter of the gun head is generally 32mm) extends into the material injection port, foaming materials are injected into the refrigerator body to be foamed through the material injection gun head, and then the foaming process is completed. Because the gap between the tip with the outer diameter of 32mm and the sprue with the diameter of 36mm is small, the relative position between the sprue tip and the sprue needs to be accurately controlled. If the deviation occurs, the phenomenon that the injection gun head collides with the injection port easily occurs, so that the injection port is deformed, and the loss of liquid leakage, even the scrapping of the box body and the like is caused.
The method for adjusting the injection gun head at present is to move the injection gun head to a position to be injected, wherein the distance between the position and the injection port is generally 500-700mm, then an operator manually controls the injection gun head to advance towards the injection port until the distance is very close (generally 5-30mm), stop the injection gun head, and then sense the relative position of the injection gun head and the injection port by visual observation or/and touch with hands at a close distance. And if the position has deviation, withdrawing the material injection gun head to the position to be injected, adjusting the position of the material injection gun head, manually controlling the material injection gun head to advance to the position 5-30mm away from the material injection port, and observing by naked eyes or/and sensing by touch with hands. And if the position is judged to be correct, the position of the gun head is adjusted, and a material injection link is started. If the position is still needed to be adjusted, the above actions are repeated until the position is determined to be correct.
The position of the material injection gun head can be adjusted only at the position to be injected, and the position is judged by naked eyes or hands, so that the process is slow, the adjustment efficiency is low, the position precision of the material injection gun head is not accurate enough, and meanwhile, the potential safety hazard also exists in manual close-range operation.
