Description

Driving device for small-pressure lower compression roller of refiner

Technical Field

The utility model belongs to the technical field of chemical fiber industry viscose short-staple refiner, it is a compression roller drive arrangement under refiner low pressure more exactly.

Background

Under the condition that the chemical fiber industry is increasingly competitive, each manufacturer puts higher requirements on the capacity of a single refiner in order to reduce the number of production lines of the refiners. The improvement of the capacity of the refiner is mainly considered from the following three aspects:

1. increasing the length of each process zone;

2. increasing the thickness of the viscose staple fiber;

3. the width of the viscose staple fiber is increased.

Considering the limited length of the plant, increasing the length of the process zone cannot be achieved. If the thickness of the viscose staple fibers is increased too much, the rinsing liquid cannot quickly permeate the viscose staple fibers and cannot rinse cleanly, the spinnability, the adhesive force, the whiteness, the elasticity and other characteristics of the viscose staple fibers are affected, and therefore the width of the viscose staple fibers is increased to be the optimal choice.

The effective width of the refiner design is 4000mm, and the viscose staple fiber is finished through a series of rinsing, extruding and other processes.

The upper compression roller of the small pressure device in the prior art adopts a main drive mode, the lower compression roller operates in a driven mode, and due to the fact that the dead weight of the lower compression roller is large, when viscose staple fibers pass through the middle of the upper compression roller and the lower compression roller, the lower compression roller is easy to generate lagging operation, the upper compression roller and the lower compression roller are asynchronous in rotation, speed difference is generated, the defects that the viscose staple fibers are not smooth in operation, abrasion is caused on the surface and the like are easily caused, and production, environmental protection and maintenance are influenced.

Disclosure of Invention

The utility model aims at providing a compression roller drive arrangement under refiner low pressure solves the problem that the compression roller can not with last compression roller synchronous operation down. The utility model discloses increase one set of independent drive arrangement for lower compression roller, form two sets of independent actuating systems with last compression roller drive arrangement. And a set of driving device is added on the lower pressing roller to extrude and convey the viscose staple fibers in each process area.

The technical scheme of the utility model:

the refiner small-pressure lower compression roller driving device comprises an upper compression roller, a lower compression roller, a small compression arm assembly, an upper compression roller driving device, a lower compression roller motor is installed at one end of a lower compression roller shaft head, a lower compression roller motor base and a lower compression roller motor are connected and fixed on a rack, two ends of the upper compression roller are fixed on pressure arms at two sides of the rack through a bearing I at the shaft end, an upper compression roller motor is installed at one end of an upper compression roller shaft head, the upper compression roller motor base and the upper compression roller motor are connected and fixed on the rack, one end of each pressure arm is hinged with the rack through a pin shaft, the other end of each pressure arm is connected with a cylinder piston rod, the other end of each cylinder is fixed on the rack, the cylinders drive the pressure arms to move along.

The upper press roller motor and the lower press roller motor are speed reducing motors. The overflow channel 8 is the same width as the viscose.

The utility model has the advantages that: adopt the utility model discloses a lower compression roller drive arrangement can make upper and lower compression roller synchronous operation, guarantees that the operation of viscose short-staple is smooth and easy, the surface is unworn, effectively improves the quality of product, has satisfied the production of equipment, uses, requirements such as environmental protection and maintenance.

Detailed Description

A process zone refiner low pressure down roll drive is shown

In a process area, a lower compression roller motor 3 is installed at one end of a shaft head of a lower compression roller 4, a lower compression roller motor base 2 and the lower compression roller motor 3 are connected and fixed on a rack 1, two ends of an upper compression roller 6 are fixed on pressure arms 10 on two sides of the rack 1 through bearings 13 at shaft ends, an upper compression roller motor 7 is installed at one end of the shaft head of the upper compression roller 6, an upper compression roller motor base 5 and the upper compression roller motor 7 are connected and fixed on the rack, one end of each pressure arm is hinged with the rack through a pin shaft, the other end of each pressure arm is connected with a cylinder piston rod 11, the other end of a cylinder 12 is fixed on the rack 1, the cylinder stretches out and draws back to drive the pressure arms to move along the pin shafts. The upper press roll motor 7 and the lower press roll motor 3 are speed reduction motors. The overflow channel 8 is the same width as the viscose.

In the device, the upper and lower compression rollers adopt mutually independent driving devices, the synchronous operation of the linear speeds of the upper and lower compression rollers is ensured by adjusting the frequency of the motor, the smooth operation of viscose staple fibers and the non-abrasion of the surface are ensured, the quality of products is effectively improved, and the requirements of production, use, environmental protection, maintenance and the like of equipment are met. During the transportation of the viscose staple fiber in each process area, the properties of spinnability, adhesive force, whiteness, elasticity and the like of the viscose staple fiber are improved under the repeated action of solvent rinsing and extrusion of an upper pressing roller and a lower pressing roller.

Firstly, injecting a required solvent into the groove through a circulating pump, and uniformly spraying the solvent on the viscose along the zigzag openings after the overflow groove is filled with the solvent; secondly, the viscose fiber extrudes the solvent when passing through the upper and lower press rollers, so as to play a role of rinsing the viscose fiber, and the gap between the upper and lower press rollers is determined according to the thickness of the viscose fiber.
