The utility model discloses a kind of automobile sheet metal edge covering is used to roll edge wheel, including fixing frame, fixed plate and roll edge mechanism, the top of fixing frame is formed with boss, the top surface of boss and the bottom surface of fixing frame are respectively provided with adjusting groove, the inside of fixing frame is symmetrically equipped with adjusting mechanism, fixed plate is collectively provided two and upper end is respectively connected with adjusting mechanism, the opposite side lower end of two fixed plates is rotatably connected with fixed disc, roll edge mechanism is collectively provided with four groups and the two ends of roll edge mechanism are respectively connected with fixed disc.The utility model is provided with four groups of roll edge mechanism, the wheel body roll edge slope angle in four groups of roll edge mechanism is different, when using, the fixed disc can be rotated by motor drive, the roll edge mechanism needed to use is rotated to lower end, reduces the problem of low efficiency caused by replacing roll edge wheel, one group of roll edge wheel is provided with heating layer, heating layer can heat wheel body, after heating, sheet metal edge covering can be softened, improve edge covering efficiency.

The utility model discloses a lining cover overlock machine, include: base is provided with sewing machine head, workbench is set up in the base, and workbench is provided with the reel, and the center line of reel is vertically arranged and is used for transverse unwinding reel belt, guide component sets up in workbench and is located reel's output, and guide component includes vertical guide plate and horizontal guide block, and the side wall of vertical guide plate is used for with the surface abutment of reel belt, and horizontal guide block is located vertical guide plate's output side, and horizontal guide block is provided with the guide groove that extends horizontally and is set through, to supply reel belt and switch reel belt to horizontal state, and sewing machine head is located guide groove's output, to sew the reel belt and process in the outer periphery of lining cover. Make reel belt accurate delivery to sew under sewing machine head, and the structure design is reasonable, solved the reel belt guiding conversion difficult, unstable delivery, low position accuracy problem in traditional overlock, effectively promoted overlock efficiency and quality, reduced manual intervention, and adapted continuous production demand.

The invention discloses a light-weight rolloff tire membrane which comprises a tire membrane body composed of a light-weight base, an anti-torsion truss and a molded surface supporting frame, the light-weight base comprises a center hub and radial branch supporting columns, and the anti-torsion truss supports the molded surface supporting frame by arranging first-stage supporting columns, inter-column reinforcing ribs and second-stage supporting columns at the tail ends of the radial branch supporting columns. The angles of the first-stage supporting columns and the second-stage supporting columns coincide or are close to the edge rolling resultant force vector direction, the annular reinforcing ribs, the inter-column reinforcing ribs and the second-stage supporting columns are selectively arranged according to load distribution, dynamic rigidity and function avoiding requirements, and a multi-stage reinforcing and tuning structure of the edge rolling tire film is formed, so that great weight reduction is achieved, and the edge rolling effect is improved. While the switching time of the rolloff tire membrane is shortened and the energy consumption is reduced, the rigidity of the rolloff tire membrane can be ensured through the flexible arrangement of the multi-stage reinforcing and tuning structure, the processing resonance is effectively inhibited, and the rolloff precision is ensured not to be influenced.

This utility model discloses an aircraft seat skin edging device, including a worktable and a glue tank. A lower mold is fixedly installed at the top center of the worktable. This utility model employs cutters and take-up rollers. During the skin edging of the aircraft seat, the take-up rollers wind and pull the skin, moving the glued, unused skin into a mating groove for easy contact with the seat back panel. After edging, multiple cutters sequentially cut off excess skin around the back panel, facilitating back panel preparation. Excess skin is then wound and rolled up by the take-up rollers, simultaneously pulling away any unused skin at the rear. This reduces the need for frequent skin handling, lowering labor intensity and offering advantages such as ease of operation and high practicality.
