[0002] With the development of industrial technology, modern parts drilling technology has become more and more perfect. A lot of fiber filaments need to be sprayed out on the spinneret, and then a lot of spinneret holes need to be drilled during the processing of the spinneret. The efficiency of the previous spinneret processing equipment is relatively low.

[0003] Patent CN119114745A discloses a four-wheel drive punching machine and a punching method for punching spinnerets, comprising: a base and a frame fixedly connected to the top of the base, a punching mechanism for punching spinnerets installed on the frame, and the punching mechanism comprises an electric cylinder fixedly connected to the frame. The present invention is not only convenient for multi-directional adjustment of the spinneret, but also can press and fix the spinneret to be processed through a clamping plate while punching the spinneret, and can squeeze the top surface of the spinneret through a pressure sensor while punching the spinneret, and transmit the pressure signal received by the pressure sensor to the controller, and control the punching motor to stop running through the controller, so as to realize the control of the punching depth, and at the same time, by rotating the adjusting bolt, and under the action of the thread of the adjusting bolt and the threaded seat, the height of the pressure sensor can be adjusted, so as to realize the control of different punching depths;

[0004] The device still has defects when in use. First, there are dozens of spinneret holes on the spinneret plate. It will take a lot of time to drill the spinneret holes one by one, which will reduce the processing efficiency. Second, the device cannot detect whether the hole diameter meets the standard, which will easily lead to unqualified products. Summary of the invention

The diameters of the three steps correspond to the diameters of the axial hole arrays on the three mold blocks one by one. A torsion cap is arranged at the top of the drill rod, and the torsion cap is in the shape of a frustum. The slope angle of the frustum matches the step slope angle of the stepped frustum, and a rubber pad is set on the outer side of the torsion cap.

Then, the three mold blocks can take turns to reach the top of the spinneret for drilling operations. In the process of the electric push rod driving the drilling motor and the drive disk at its output end to move downward, the bottom step of the stepped truncated table will contact the first set of torsion caps and drive them to rotate rapidly. The drill rod under the torsion cap will open a circular array of holes on the spinneret. After the three sets of drill rods take turns to open a circular array of holes on the spinneret, three circles of holes will be formed on the spinneret, achieving the effect of efficient hole opening.

[0015] Secondly, after the spinneret is opened, the pressing cylinder drives the guide rod to separate from the fixed platform, and then the spinneret falls into the interior of the detection tube. The spinneret eyes on the spinneret will be inserted along the detection needle for detection. If the spinneret eyes cannot fall completely along the detection needle due to their own gravity, it means that the spinneret eyes on the spinneret are unqualified in diameter, so that unqualified products can be preliminarily screened out. During the process of the spinneret falling, it will be buffered by the metal preservative inside the detection tube, and the surface of the spinneret can be taken out for packaging after being covered with the metal preservative.
