a line device

Abstract

The invention discloses a paying-off device. The paying-off device comprises an iron plate as well as a paying-off tip and a pushing rod which are arranged on the iron plate, wherein the paying-off tip is a trapezoidal tooth left-hand thread pushing rod; the head of the paying-off tip presents a conical design; the pushing rod comprises a chain wheel, a chain connected with the chain wheel, an action brake for controlling the chain wheel to stop a movement, an action belt connected with the action brake, and an adjustment rod for adjusting the action brake; the paying-off device is a dual-purpose paying-off frame, and further comprises an n-shaped lever, a bearing bush pin element connected with the n-shaped lever, and a pull ring self-locking device. The paying-off device disclosed by the embodiment of the invention is simple and practical in structure, accelerated in tray loading speed, and stable in action; a tray cannot fall off due to inertia after scram, and staffs cannot operate if dropping out a program, thus the working tray is comprehensively protected, production equipment in next step is protected, potential safety hazards are avoided, and production efficiency is increased simultaneously.

Description

technical field [0001] The invention relates to the technical field of pay-off, in particular to a pay-off device. Background technique [0002] The existing pay-off device is basically a wheeled lifting device in the direction of the screw mandrel and a lever-locked pay-off device. But these structures also have certain disadvantages. The upper top of the shaft type is too cumbersome; the shaftless type has one more lift, and can have a sufficient height; the shafted pay-off device with bearing bushes allows employees to run without the top, which will cause jumping and dry friction, which will seriously damage the plate. For the top inner hole, the upper machine vibrates due to slight loose clamping, which will cause loud startup noise and mechanical vibration. In severe cases, it will fly out of the equipment during high-speed rotation, causing equipment damage and personnel safety. There are generally similar in the same industry. The phenomenon is even worse if the ma...

However, these structures also have certain disadvantages

The upper top of the shaft type is too cumbersome; the shaftless type has one more lift, and can have a sufficient height; the shafted pay-off device with bearing bushes allows employees to run without the top, which will cause jumping and dry friction, which will seriously damage the plate. For the top inner hole, the upper machine vibrates due to slight loose clamping, which will cause loud startup noise and mechanical vibration. In severe cases, it will fly out of the equipment during high-speed rotation, causing equipment damage and personnel safety. There are generally similar in the same industry. Phenomenon, poor management is even worse
