Problems solved by technology
However, the existing air knife vertical lifting adjustment mechanism and axial rotation adjustment mechanism do not have a special locking mechanism. When manual misoperation occurs, the position of the air knife will be changed.
The long-term vibration of the frame when the casting machine is working can also easily cause the air knife to move in the vertical direction or rotate in the axial direction, so that the air knife blowing nozzle deviates from the best process position between the surface of the quenching roller and the die lip, which affects Mass of plastic slabs

The present invention is a locking device for the position of the air knife of the casting machine. The supporting plate of the lifting and locking mechanism is fixed on the front end of the bottom plate. The screw hole of the supporting plate is opposite to the taper hole of the pressing plate fixed on it. In the small elastic taper sleeve of the hole, the locking pin passes through the through hole of the pressure plate, and the locking nut and the locking handle are installed on it. The lock handle rotates the lock nut to press the deep groove of the compression plate to close, the small elastic taper sleeve tightly embraces the input shaft of the elevator, and the air knife is locked in the vertical direction. The compression seat of the rotation locking mechanism is fixed on the reducer, and the long axis that drives the air knife to rotate is inserted into the large elastic taper sleeve in the center hole of the compression seat, and the rotation locking pin passes through the through hole of the compression seat, and the rotary lock pin is installed on it. Lock nut and twist lock handle. The rotary locking handle rotates the rotary locking nut to press the deep groove of the pressing seat to close, the small elastic taper sleeve tightly embraces the long axis, and the air knife is locked in the direction of rotation. The invention ensures that the position of the air knife is fixed and reliable, has a simple structure, and is easy to implement and use on an existing casting machine.
Description
technical field [0001] The invention relates to the structure of a casting machine for plastic film production, in particular to a locking device for the position of the air knife of the casting machine. Background technique [0002] The casting machine for plastic film stretching is equipped with an air knife behind the quench roll. After the raw material is extruded from the die head, under the action of the cold air flow of the air knife blowing nozzle, it is quickly attached to the surface of the quenching roll to form a thick sheet. [0003] In order to ensure the quality of thick sheet forming, the air knife is required to be parallel to the die lip and keep a certain distance from the surface of the quenching roller. At present, the air knife on the support is adjusted to allow the air knife to rise and fall in the vertical direction, and to rotate axially, so that the relative position between the air knife blowing nozzle and the surface of the quenching roller and ...
