AI Technical Summary

Technical Problem

In existing unwinding devices for degreased cotton production, the handle is rigidly connected to the lead screw, which requires manual torque application when adjusting the expansion plate. This can easily cause hand slippage, and the operation is unstable, especially when the degreased cotton roll is too tight.

Method used

The servo motor drives the connecting plate, which connects to the socket via a plug rod, enabling the servo motor to drive the handle rotation and avoiding manual rotation. Combined with the locking component and return spring design, it ensures operational stability and convenience.

Benefits of technology

It improves the operational precision and stability of the unwinding device, reduces the risk of hand slippage, simplifies the equipment maintenance process, and enhances maintenance convenience.

Abstract

This utility model belongs to the field of degreased cotton unwinding technology, and particularly relates to an unwinding device for degreased cotton production. It includes a roller body, a lead screw rotatably connected inside the roller body, a handle at the front end of the lead screw, and a movable block threadedly connected to the outside of the lead screw. Multiple sets of extension plates are installed on the outside of the movable block. A connecting seat is installed outside the handle, and a detachable servo motor is installed outside the connecting seat. When the motor mounting seat drives four sets of positioning rods to insert into four sets of positioning holes on the positioning seat to complete the installation, multiple sets of insertion rods on the connecting plate at the output end of the motor mounting seat are inserted into multiple sets of insertion holes on the connecting seat, thus connecting the connecting plate and the connecting seat. This allows the servo motor to drive the connecting plate to rotate, enabling the connecting seat to apply torque to the handle under the action of the connecting plate. Therefore, manual rotation of the handle is unnecessary, preventing hand slippage during operation and improving the accuracy and stability of the equipment operation.
