High-efficiency winding machine for flexible graphite metal spiral wound gasket

Abstract

The invention relates to a high-efficiency winding machine for a flexible graphite metal spiral wound gasket, which mainly comprises a transmission mechanism and a winding feeding mechanism. In the transmission mechanism, an electric motor is connected with a speed reducer; an output shaft of the speed reducer is provided with a coupling and is connected with a compression wheel shaft; the compression wheel shaft is supported on a fixed support by adopting a bearing through a compression wheel shaft right end cover; a guide round rod is welded on the peripheral plane of an end cover support; the upper end of the guide round rod is welded with a welding block; a steel wire rope passes across a pulley on a fixing device; and the other end of the steel wire rope is connected with a counter weight. In the winding feeding mechanism, a graphite ribbon is connected between a compression wheel and a graphite ribbon reel; a guide block is arranged at the position between the graphite ribbon and a metal belt; the metal belt passes across an A wheel to be connected with a fixed arm arranged below the A wheel; and an eccentric mechanism is arranged between the A wheel and the fixed arm. According to the invention, quality of a domestic spiral wound gasket can be improved, so that the domestic spiral wound gasket meets more and more harsh working conditions in large-scale chemical production equipment; and the high-efficiency winding machine for the flexible graphite metal spiral wound gasket has more complete functions and a higher automation degree.

Description

technical field [0001] The invention relates to a high-efficiency winding machine for a flexible graphite metal wound gasket, belonging to the technical field of petrochemical sealing. Background technique [0002] Sealing is a commonly used technical means in the industrial field, and its essence is to prevent the mass exchange between the sealed space and the surrounding medium. Sealing can cut off the fluid (or medium) channel, block or isolate the fluid channel in the fluid delivery system, and prevent the fluid from leaking out. In general industrial equipment, in order to achieve a good sealing effect, most of them use static sealing. Starting from the design of the static sealing device, it is required that the device is reliable, has a long working life, and strives for compact structure, simple system, convenient manufacture and maintenance, and low cost. Gasket seal is a kind of static seal, which is widely used in various sealing occasions, with good effect and ...

AI Technical Summary

Problems solved by technology

However, according to preliminary investigations, the equipment of domestic seal manufacturers is simple, the technology is backward, the production of wound gaskets is at a low level, and the quality is very unstable

The wound gaskets produced are either exposed with bare metal strips or extruded too much non-metal strips, which directly affects the appearance and quality of the gaskets

In addition, in the current winding process, it is difficult to continuously adjust and quantitatively control the tension and compression force of the metal strip. The non-metallic filler strip is added manually, and the thickness of the gasket winding is measured manually. It is impossible to reach the specified thickness of the gasket. Timely cutting and stopping the feeding of the belt, resulting in low production efficiency, unstable product quality, and large human factors, which affect the mechanical properties and sealing performance of the gasket
