AI Technical Summary
Existing extrusion dies have shortcomings in terms of thickness uniformity and consistency. The hot bolt adjustment is greatly affected by external factors and is costly. The automatic fine-tuning structure of the electric cylinder has extremely high requirements for the electric cylinder, making it difficult to achieve full automation and cost control.
A servo push rod motor drives the rocker arm, which amplifies the force through the lever principle to achieve automatic fine adjustment of the mold lip. The linear motion of the servo push rod motor acts on the rocker arm, and the lever principle of the rocker arm amplifies the force to push or pull the push-pull rod to adjust the lip gap.
It enables precise adjustment of the die lip gap, reduces the requirements for electric cylinders, reduces costs, improves the thickness uniformity and consistency of extruded products, and achieves more efficient automated control.

[0016] On the basis of the above scheme, the push-pull rod 47 front end is in contact with the front side of the deformation groove 11, and the fine-tuning pull hook 48 front end is in contact with the rear side of the pull slot 13; when the fine-tuning swing rod 44 swings, the push-pull rod 47 moves forward by extruding the front side of the deformation groove 11 to reduce the extrusion channel gap of the die lip opening, and when the fine-tuning swing rod 44 swings, the push-pull rod 47 moves backward by extruding the rear side of the pull slot 13 to expand the extrusion channel gap of the die lip opening.
[0017] In addition, the connecting frame 41 is also provided with a servo push rod motor control chamber, and each servo push rod motor 42 is controlled separately after being connected by communication cable.
[0018] In addition, the lever ratio of the fine-tuning swing rod 44 is greater than or equal to 1:10, a smaller force is applied by the servo push rod motor 42, and at least ten times amplification is realized through the force arm of the fine-tuning swing rod 44, so that a smaller servo push rod motor 42 can be selected to realize the push-pull of the die lip opening gap.
[0019] The working principle of the present application is as follows:
[0020] When the gap of the mold lip at a specified position needs to be adjusted, the servo push rod motor 42 corresponding to the position is controlled to move, and finally outputs a linear motion acting on the connecting block 43, and the force is vertically applied to the rear end of the fine adjustment swing rod 44. There are actually two kinds, one is to pull the fine adjustment swing rod 44 upward, and the other is to push the fine adjustment swing rod 44 downward. The corresponding fine adjustment swing rod 44 rotates upward or downward around the hinge shaft at the front end.
[0021] When the fine adjustment swing rod 44 rotates upward around the hinge shaft at the front end, the clamping column 441 pushes the clamping groove 471 backward, so that the push-pull rod 47 moves backward, drives the fine adjustment pull hook 48 to pull the pull groove 13 to move backward, controls the deformation of the mold lip 12 at the region, and makes the mold lip opening gap larger.
[0022] Similarly, when the fine adjustment swing rod 44 rotates downward around the hinge shaft at the front end, the clamping column 441 pushes the clamping groove 471 forward, so that the push-pull rod 47 moves forward, the front end of the push-pull rod 47 pushes the mold lip 12 to move forward, the mold lip 12 at the region is deformed, and the mold lip opening gap is smaller.

Any simple modification, equivalent change or modification made according to the technical principles of the present application to the above embodiments still belongs to the scope of the technical solutions of the present application.
