A single row double eccentric wheel shaker

Abstract

The invention relates to a single-row double-eccentric-wheel type shaking machine and aims at providing the single-row double-eccentric-wheel type shaking machine which can improve the finished paper evenness of a high-speed paper machine and physical indexes and meanwhile has low acting force on an installing base during high-speed operation. The technical scheme is that the single-row double-eccentric-wheel type shaking machine is provided with a support, a shaking frame fixed on the support and a paper making machine screen portion and is characterized by further comprising a drive part, a vibration part and an output part, wherein the drive part is a motor, the vibration part comprises a coupler connected with an output shaft of the motor, spring plates fixed in the vertical direction of the bottom or the top of the shaking frame and a core frame hung between the spring plates. A driving shaft and a driven shaft are vertically arranged on the core frame, the driving shaft is connected with the coupler, meshed gear pairs are installed on the driving shaft and the driven shaft, and two sides of each gear are provided with eccentric block groups adjustable in eccentric angle. The output part is a shaking rod.

Description

technical field [0001] The invention relates to auxiliary equipment for a papermaking former, in particular to a single row double eccentric wheel shaker. Suitable for paper industry. Background technique [0002] With the improvement of people's living standards, the requirements for various daily necessities are getting higher and higher. As one of the daily necessities commonly used by people, the quality requirements for paper are getting higher and higher; The horizontal vibration of the table can obviously improve the quality of the paper. This kind of vibration is called shaking in the paper industry, and the equipment that produces this kind of vibration is called a shaking machine. As the speed of the paper machine is getting higher and higher, the current old-fashioned eccentric wheel vibrating machine cannot even the pulp well because the vibration frequency is too low (generally only up to 300rpm), and the old-fashioned vibrating machine has a great force on the...

AI Technical Summary

Problems solved by technology

As the speed of the paper machine is getting higher and higher, the current old-fashioned eccentric wheel vibrating machine cannot even the pulp well because the vibration frequency is too low (generally only up to 300rpm), and the old-fashioned vibrating machine has a great force on the foundation. Due to the problem of inertia, the old-fashioned vibrating machine cannot be used for high-speed paper machines with a speed of more than 400 m / min.
