Voice frequency core wire disengaging device

Abstract

The invention discloses a voice frequency core wire disengaging device which comprises a cylindrical rotating shaft (1). The outer circumferential face of the rotating shaft (1) is provided with at least one circle of spiral groove (2). The upper end face of the rotating shaft (1) is provided with upper through holes (3) communicating with the upper ends of the grooves (2). The side wall of the rotating shaft (1) is provided with a lower through hole (4) which penetrates through the rotating shaft (1) in the radial direction and communicates with the lower ends of the grooves (2). A tubular body (5) communicating with the lower through hole (4) is arranged on the side wall of the rotating shaft (1). The lower end of the rotating shaft (1) is provided with a base (6) in rotating connection with the rotating shaft (1). The rotating shaft (1) is connected to the base (6) in a rotating mode through a deep groove ball bearing (7). A boss (8) coaxial with the rotating shaft (1) is arranged below the base (6). The diameter of the boss (8) is matched with that of a large hole of a core wire coil. The voice frequency core wire disengaging device has the advantage of avoiding the phenomenon that economic losses and time losses are caused by clamping stagnation possible happening in the disengaging process of the core wire coil of core wires.

Description

technical field [0001] The invention relates to an audio core wire release device, in particular to an audio core wire release device used on an audio core wire pre-processing assembly line. Background technique [0002] Such as Figure 4 As shown, the inside of the core wire coil is a mandrel with radially convex steps at both ends. There is a large hole through the middle of the mandrel, and the core wire is wound on the mandrel; the core wire coil is placed on the ground , during the process of the core wire being conveyed upward, the core wire is naturally disengaged on the core wire coil round by circle. Due to the burrs on the outer edge of the upper end of the mandrel or the notch caused by bumping during transportation, the core wire is in the process of disengagement. Jamming may occur, which may lead to two consequences: (1) The core wire is stuck, causing the core wire to break, wasting raw materials and causing economic losses, and causing time loss due to mainte...

Problems solved by technology

[0002] like Figure 4 As shown, the inside of the core wire coil is a mandrel with radially convex steps at both ends. There is a large hole through the middle of the mandrel, and the core wire is wound on the mandrel; the core wire coil is placed on the ground , during the process of the core wire being conveyed upward, the core wire is naturally disengaged on the core wire coil round by circle. Due to the burrs on the outer edge of the upper end of the mandrel or the notch caused by bumping during transportation, the core wire is in the process of disengagement. Jamming may occur, which may lead to two consequences: (1) The core wire is stuck, causing the core wire to break, wasting raw materials and causing economic losses, and causing time loss due to maintenance; (2) After the core wire is stuck, the The pulling force of the assembly line finally passed, but the core wire was elongated and deformed under the action of the pulling force, and the produced products were unqualified and discarded, resulting in economic losses

[0003] Therefore, the existing method of naturally releasing the core wire from the core wire reel has the disadvantages of possible stagnation, resulting in economic loss and time loss.
