A272F and type of aircraft platform feeding transformation mounted A272F and type of aircraft 12. Due to lower feed sliver platform, carding sliver almost at full cylinder are higher platform and bars circle. In and the machine is running, sliver above the bars caused sliver lap run to the bottom, so close to the platform sliver sliver barrel is friction scared, serious sliver friction but is attached to the other sliver produce bamboo strips, affecting the quality of evenness, weight unevenness and finished products.

To overcome such drawbacks, glass wool carpets improve product quality, our A272F and type of aircraft for the corresponding transformation. After repeated demonstration design, fabricated and machine overhead feed system, commissioning effect of contrast, will be finalized on the basis of the original machine is fed to a high shelf platform actively feeding, can improve the quality of sliver.

Through more than three months of pre-production, after the transformation overhead feed system running smooth, safe and reliable. Easy maintenance, less investment, sliver weight unevenness can be increased 10.8%.

Specific rehabilitation programs are: (1) self-made "J" shaped cotton roll elevated guide support rod in the original roll bars seats (front and rear seat) on (with a 30 mm × 30 mm square hollow steel tubes) (see Figure 1); rubber injection molding machine In support rod plane milling long holes for adjusting belt tension; Plane drill two holes the same size with the bearing hole. Horn and do according to the geometry of the bearing seat system. (2) roll bars with a diameter of 48 mm thin-walled tube to reduce weight, the length and the same length as the original roll bars, roll bars and ensure concentric with the shaft head when the difference is less than 0 .10 mm processing. (3) Bearing Block can be made, with double row bearings 1205, retaining oil cap each car four. (4) The guide is available cotton fork fork Replacement cotton roving guide, each sliver of three, guided cross strut claim cotton smooth surface is not wounded in action, do not rub when strut positioned to note is appropriate. (5) In the original roll bars connecting shaft <part number A272-04147 (left), A272-04148 (right)> pick one end of the long bars roll milling a 6 mm wide groove for holding the tape wheel. (6) the main transmission belt wheel diameter of 80 mm (single slot). Elevated on the tape wheel diameter of 88 mm, tape model A1374. (7) In order to make the elevated smooth in operation, can be added in the elevated rear end of the column.
