The utility model adopts the structural foam as the filling material to be filled in the cavity of the cloth guide roller, provides larger rigidity for the cloth guide roller by utilizing the characteristics of low density and high strength of the structural foam, and simultaneously provides prestress for the roller surface of the thin-wall steel tube, so that the cloth guide roller has certain elasticity, and the plastic deformation of the cloth guide roller after being stressed is prevented.
Description
Technical Field
The utility model belongs to the technical field of textile printing and dyeing machinery, and particularly relates to a commonly used prestress high-rigidity cloth guide roller in the printing and dyeing machinery.
Background
The fabric guide roll is the most common general device in open width dyeing and finishing equipment. Its main function is to support and guide the fabric in a definite direction of travel and to adjust the tension of the fabric in the direction of travel. Because the fabric guide roller needs to bear the tensile force of the warp direction of the fabric for a long time in order to prevent the fabric from wrinkling in the working process, the fabric guide roller is required to have higher rigidity and certain toughness, and the fabric guide roller is prevented from deforming under stress or is ensured to deform after being stressed and cannot be restored.
The traditional cloth guide roller is formed by nesting and sleeving double-layer or multi-layer metal plates and then placing the metal plates into a die, rolling the two-layer or multi-layer thin steel plates into a cylinder, and tightly combining the two-layer or multi-layer thin steel plates into a whole through sleeving and pressing and an inner roller after the processes of welding, spot welding and the like so as to improve the integral rigidity. The composite cloth guide roller uses double-layer or multi-layer steel plates, and the whole wall thickness of the guide roller is larger, so that the weight is larger, and the sensitivity of tension detection and adjustment is reduced when the composite cloth guide roller runs at lower tension.
There are also single-layer hollow lightweight fabric guides filled with filling foam in the prior art, which have the advantages of light weight and high sensitivity for tension detection and adjustment. However, since the lightweight fabric guide roll is filled with only filling foams such as polyurethane, these filling foams cannot provide high rigidity to the external roll surface, and cannot provide sufficient stress support to prevent the roll surface from generating plastic deformation which cannot be recovered.
Disclosure of Invention
The utility model aims to provide a prestressed high-rigidity cloth guide roller which has higher rigidity and certain elasticity aiming at the defects of the existing cloth guide roller.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a prestressing force high rigidity fabric guide roller, includes two disconnect-type roller shafts that have the flange, the parcel in the flange outside has thin-walled steel pipe roll surface, will the roller shaft is connected as a whole that has hollow cavity, its characterized in that: the cavity is filled with structural foam. The structural foam is a foam material modified by a penetrating aromatic amide polymer network based on plastic PVC, and has the characteristics of low density, high strength and good ductility. Since structural foams can provide progressive structural strength during curing and provide a greater range of resilience after curing. Therefore, the fabric guide roller filled with the structural foam has higher rigidity and certain elasticity to prevent plastic deformation after being stressed.
It is further characterized in that: and an inner side flange and an outer side flange are respectively arranged on the two roll shafts. The plurality of flanges are arranged, so that better support can be provided for the roller surface of the thin-wall steel pipe, and meanwhile, the roller shaft and the roller surface of the thin-wall steel pipe can be quickly positioned, so that the concentricity is ensured.
Further: the outside flange sets up the roller middle part, the inboard flange sets up roller one end. The structure can better provide supporting force for the roller surface of the thin-wall steel pipe.
Further: the outer flange is provided with an injection hole, and the inner flange is provided with a lightening hole with a large diameter. The injection holes on the outer flange facilitate the injection of foam, while the injection holes on the other side facilitate the evacuation of air. The large-area lightening holes not only enable structural foam to smoothly enter the cylindrical cavity, but also reduce the overall weight of the cloth guide roller.
Preferably: the material of the thin-wall steel pipe roll surface is stainless steel.
The utility model adopts the structural foam as the filling material to be filled in the cavity of the cloth guide roller, provides larger rigidity for the cloth guide roller by utilizing the characteristics of low density and high strength of the structural foam, and simultaneously provides prestress for the roller surface of the thin-wall steel tube, so that the cloth guide roller has certain elasticity, and the plastic deformation of the cloth guide roller after being stressed is prevented.

FIG. 1 is a schematic view of the structure of the present invention.
Detailed Description
As shown in fig. 1, the prestressed high-rigidity cloth guide roller comprises two roller shafts 1, wherein the middle parts of the roller shafts 1 are provided with outer side flanges 2, and the end parts of the roller shafts are provided with inner side flanges 3. The outer sides of the inner flange 3 and the outer flange 2 are wrapped by thin-wall steel pipe roll surfaces 4 made of stainless steel materials, the roll shaft 1 is connected into a whole with a hollow cavity, and structural foam 5 is filled in the cavity. The outer flange 2 is provided with an injection hole, and the inner flange 3 is provided with a lightening hole with a large diameter.
The thin-wall steel pipe roll surface 4 is formed by rolling a single-layer stainless steel plate according to the diameter requirement, and is welded and polished to be a tubular roll surface after splicing. The roundness and straightness indexes of the cylindrical surface of the tubular roller surface are ensured through a rolling circle process. And two ends of the tubular roller surface after the windlass is round are respectively welded with a set of double-flange half shafts as output shafts. The outer flange 2 of the double-flange half-shaft is provided with injection holes to facilitate the injection of foam and the exhaust of air on the other side. The flange 3 on the inner side of the double-flange half shaft is provided with large-area lightening holes, so that the weight of the double-flange half shaft is lightened except that foam smoothly enters the cylindrical cavity. After the structural foam is filled in the tubular roller surface, the roller surface is turned on a lathe after the foam is solidified to adjust the concentricity of the two half shafts and the overall balance.
