Description

Quick reel changing device of spunlace machine

Technical Field

The utility model belongs to the technical field of spunlace non-woven fabrics, and particularly relates to a quick roll changing device of a spunlace machine.

Background

The traditional A-shaped frame in China has 2 moving wheels at one end, two supporting frames at the other end, when a floating cylinder is replaced, the end of each supporting frame needs to be jacked off the ground by a small trailer, about 3000kg of the A-shaped frame (the weight of the A-shaped frame and a blank cloth roll) is manually dragged to leave a winding platform of a spunlace machine, a large amount of manpower and time for replacing the floating cylinder is needed in the operation process, the spunlace machine cannot stop but continuously produce grey cloth when the floating cylinder is replaced, the grey cloth stored in the cloth storage frame accumulating about 500 meters waits for winding, and the phenomenon of inner layer folding, irregularity and the like exists in the rewinding process. And there is a safety risk in the process of changing the float drum. The reel changing device used by the enterprise at present needs to manually push and pull the float cylinder. The push-off reel replacement at least needs more than two labors to work simultaneously, and the influence of uneven inner layer reeling is reduced by reducing the speed of the spunlace machine when the floating drum is replaced.

For example, patent application No. CN 201920379561.5 discloses a shaftless winding device for a spunlace machine, which comprises a winding frame arranged in the left-right direction, a cloth pressing roller capable of pressing the circumferential surface of a fabric and driving the fabric to rotate, and two groups of floating drum supporting units symmetrically arranged on the left and right sides of the winding frame and used for supporting floating drums, wherein the floating drums are arranged in the left-right direction, and the left and right ends of the floating drums are respectively rotatably arranged on the two groups of floating drum supporting units; the floating barrel supporting unit comprises a folding positioning rod and a fixed positioning rod which are used for preventing the floating barrel from shaking forwards and backwards, an anti-lateral-movement guide wheel which is used for preventing the floating barrel from shaking leftwards and rightwards and two supporting guide wheels which are used for supporting the floating barrel; the folding positioning rod and the fixed positioning rod are both arranged on the winding rack along the vertical direction and are respectively positioned on the adjacent outer sides of the front side and the rear side of the floating barrel, and the upper part of the folding positioning rod can turn back and forth far away from the floating barrel; the two supporting guide wheels are arranged on the rolling frame in parallel in front and back and are positioned between the turnover positioning rod and the fixed positioning rod and are respectively tangent with the front side and the back side of the lower part of the floating barrel; the side shift prevention guide wheel is arranged on the rolling rack in the vertical direction and is positioned on the adjacent outer side of the bottom of the end face of the floating barrel.

For the winding device, according to statistics, every roll change is realized by simultaneously coordinating two skilled operators, but the two skilled operators can normally wind the fabric roll in at least 30 minutes, then the two operators can drag 100 meters of the fabric roll of nearly 3 tons to be sent to a bleaching and doffing workshop simultaneously, the whole operation is time-consuming and labor-consuming, the whole spunlace line abnormally works for 30 minutes, 8 rolls of fabric are produced in 24 hours every day, namely 30X8=240 minutes is wasted every day, nearly 4 hours of normal production time can completely produce one more roll of product, the operation risk coefficient is large, and the manual labor of staff is high.
