Embodiment Construction

[0029] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0030] like figure 1 , figure 2 As shown, a slitter unwinding double floating roller mechanism includes a frame 10, a first guide roller 1, a second guide roller 2, a driving floating roller 3, a driven floating roller 4, a connecting rod 5 and an air cylinder 6. The driving floating roller 3 and the driven floating roller 4 are arranged between the first guiding roller 1 and the second guiding roller 2, and the material bypasses the first guiding roller 1, the second guiding roller 2, the driving floating roller 3 and the driven floating roller 4 and tensioned.

[0031] Both ends of the active floating roller 3 are respectively connected with active floating rol...

Abstract

The invention discloses a splitting machine unwinding double-floating-roller mechanism and a closed-loop control method thereof. The splitting machine unwinding double-floating-roller mechanism comprises a driving floating roller, a driven floating roller, a cylinder and a connecting rod. The driving floating roller is connected with a driving floating roller swing arm. The driving floating rollerswing arm swings round a first rotary shaft. The cylinder drives the driving floating roller swing arm to swing. The driven floating roller is connected with a driven floating roller swing arm. The driven floating roller swing arm swings round a second rotary shaft. The two ends of the connecting rod are hinged to the driving floating roller swing arm and the driven floating roller swing arm correspondingly. The cylinder is driven by a motor. The motor is connected with a controller. A linear potentiometer is fixedly installed on the cylinder. When tightness of materials changes, the cylinderstretches out or retracts, the linear potentiometer on the cylinder detects change of the position of the cylinder, a voltage change signal is fed back to the controller, the controller adjusts the rotation speed of the motor, and thus the cylinder returns to the balance position. The splitting machine unwinding double-floating-roller mechanism provided by the invention is good in responsiveness,high in tension control precision and good in static and dynamic balance.

Description

technical field [0001] The invention relates to a floating roller mechanism on a slitting machine, in particular to a slitting machine unwinding double floating roller mechanism and a closed-loop control method thereof. Background technique [0002] In the field of slitting and winding applications, problems such as poor roundness of slitting parent rolls, large tension fluctuations, and easy stretching and deformation of small tension materials seriously affect the quality of winding film rolls, such as material stretching deformation, wrinkles, Scratches, etc., thereby affecting the production of the subsequent process, and even causing the product to be scrapped. [0003] The main function of the floating roller on the existing slitting and unwinding machine is to establish tension on the material to be slitting and unwinding, and keep the unwinding tension stable, and at the same time buffer the fluctuation caused by the out-of-roundness of the parent roll to ensure that...
