The utility model discloses a centrifugal film
machine with safety door belongs to centrifugal film
machine field, has solved the problem that the door body is opened because of the misoperation, and the technical scheme of solving this problem mainly includes the frame body, is equipped with controller,
drive motor, the drum rotating by
drive motor drive in frame body, and the injection film mechanism and heating mechanism, is equipped with first sensor on the drum, and the front side of frame body is provided with the door body, is equipped with the locking piece for locking the door body on the frame body, and the side of drum towards the door body forms the entrance, and heating mechanism sliding installation is in the door body, is equipped with second sensor for detecting the distance between heating mechanism and the door body on the door body, and the controller is equipped with the rotating speed threshold value and
distance threshold value, and the locking piece only when the rotating speed of drum is lower than the rotating speed threshold value and the distance between heating mechanism and the door body is less than the
distance threshold value, releases the locking of the door body. The utility model mainly is used to ensure that the door body can only open when the rotating speed of drum is lower and heating mechanism is separated from the drum.
