AI Technical Summary

Technical Problem

When the existing fine wire release device is knotted, the external driving mechanism cannot pull the fine wire, which can easily lead to the fine wire breakage and damage, and the thread release frame may rotate due to inertia, causing the fine wire to loosen and fall off.

Method used

A fine wire laying device including a trolley and a multi-section spring telescopic member is designed. When the precision wire pull is blocked, the external drive mechanism drives the car to move, and the distance sensor stops the machine to check the fault after detection. The multi-section spring telescopic element drives the car to reset, increasing the operating resistance to prevent collision. At the same time, the limit plate is driven by the rotation of the wire mount, and the spring member is used to apply elastic pressure to the linking arm, so that the roller always fits the limit plate, reducing the inertia rotation of the wire mount.

Benefits of technology

It effectively reduces the breakage and damage caused by the drive mechanism being unable to pull the fine line when knotted, reduces the loosening and falling off of the fine line caused by inertia rotation of the wire laying frame, ensures the stability of the movement of the car, and reduces the phenomenon that the car breaks off the limit rail.

Abstract

The utility model discloses a fine line paying-off device which comprises a bottom plate, a first side baffle is arranged on one side of the top end of the bottom plate, a second side baffle is arranged on the other side of the top end of the bottom plate, two limiting rails are arranged on the inner wall between the second side baffle and the first side baffle, a trolley is arranged above the two limiting rails, and wheels are installed at the corners of the bottom end of the trolley. A second side connecting base is arranged on the outer wall of one side of the trolley, a first side connecting base is arranged on the outer wall of the side, away from the second side connecting base, of the trolley, a side connecting plate is arranged on the outer wall of the side, away from the trolley, of the second side connecting base, and two multi-section type spring telescopic pieces are installed on the inner wall of a second side baffle. According to the utility model, the phenomenon that the driving mechanism cannot pull the fine line to cause breakage and damage when the fine line is knotted can be reduced, the phenomenon that the fine line is loosened and falls off on the outer wall of the pay-off rack when the fine line is paid off is also reduced, the stability of the trolley during movement is ensured, and the phenomenon that the trolley is separated from the upper part of the limiting rail is reduced.
