Unreeling stand allowing electric push rod to rotate around shaft in reciprocating manner

Abstract

The invention provides an unreeling stand allowing an electric push rod to rotate around a shaft in a reciprocating manner. The unreeling stand comprises a supporting wallboard, a reciprocating rotary shaft, a moment arm, a speed reducer, a motor and a bearing pedestal, wherein a large end of the moment arm is connected with the reciprocating rotary shaft; a small end of the moment arm is connected with the speed reducer; the motor and the bearing pedestal are connected with the speed reducer; the speed reducer is provided with an output thread push-pull rod, and is connected with the small end of the moment arm through the output thread push-pull rod; and the reciprocating rotary shaft, the speed reducer, the motor and the bearing pedestal are all mounted on the supporting wallboard. The motor and the speed reducer are adopted to drive the reciprocating rotary shaft through the moment arm, the device has a simple structure, and is safe and convenient to use, the yield is stable, the product quality is ensured, pipelines need not to be replaced, the problems of oil circuit leakage and response lag are solved well, and the environmental protection is facilitated while a realistic measure is provided for the full automation.

Description

technical field [0001] The invention relates to the field of paper product processing, in particular to an electric push rod reciprocating around an axis to unwind a paper frame. Background technique [0002] The reciprocating rotary shaft of the unwinding frame of the post-processing and cutting machine for paper products usually uses a hydraulic cylinder device as the power source. The cylinder piston pushes the arm, so that the reciprocating rotary shaft fixed on the arm can rotate around the axis. The high-pressure oil produced by the hydraulic press is connected to the input and output ports of the oil cylinder through metal oil pipes and high-pressure composite rubber oil pipes. The high-pressure oil output from the high-pressure oil station can be transmitted to the oil cylinder without loss, and the designed effective thrust can make the reciprocating and turning mechanism rotate through the lever system. The length of the oil pipeline directly affects the response...

Problems solved by technology

Regular replacement of pipelines is a prerequisite for safe production, but this increases production costs to a certain extent; moreover, some common faults may occur in the oil pressure transmission system, such as: leakage of the delivery pipe, oil leakage from the opening of the gasket, and leakage of the nozzle joint Wait, it's inconvenient to use

The general leakage phenomenon not only pollutes the environment, but also affects the product quality. In serious cases, it will directly affect the normal production, and even stop the machine for repair.
