The even pulling force feedway of this film is driven by main, the volume heart drives and shock absorber three parts constitute, it is characterized in that: the main driving comprises primary transducer, main motor and main drive roll, primary transducer links to each other with main motor, main motor links to each other with main drive roll by transmission device, the volume heart drives and comprises from frequency converter, volume heart drive motor, swelling winding reel and thin film disk, link to each other with volume heart drive motor from frequency converter, volume heart drive motor links to each other with the swelling winding reel by transmission device, thin film disk loads on the swelling winding reel, be tied with film to be carried on the thin film disk, shock absorber comprises 1～6 of stationary roll, 1～5 of dancer, guide rail, slide block and displacement detector, guide rail is fixedly mounted on the substrate, dancer is fixedly on the slide block, slide block is entrenched in the chute of guide rail, dancer is positioned at the below of stationary roll, displacement detector is contained on the substrate of slide block top, film comes out from thin film disk, respectively on stationary roll and dancer, at last on main drive roll, displacement detector and be electrically connected from frequency converter.
The utility model has adopted the displacement detector of high precision, fast-response, adopted frequency converter with closed loop technology controlling and process, the shock absorber mechanical friction is very little, the linear velocity of the linear velocity energy real-time tracking main drive roll of film, so speed synchronization precision height, machine run is stable, and film does not have tensile deformation, and Thinfilm pattern is undistorted.
Description of drawings
Fig. 1 is the utility model constructional drawing: 1, primary transducer, 2, main motor, 3, stationary roll, 4, displacement detector, 5, thin film disk, 6, from frequency converter, 7, volume heart drive motor, 8, tensioning winding reel, 9, the break-in roller, 10, dancer, 11, guide rail, 12, slide block, 13, main drive roll, 14, film.
The specific embodiment
In conjunction with tissue wrapping machine speed synchronization control setup, details are as follows to the utility model: primary transducer (1) links to each other with main motor (2), control the rotating speed of main motor (2), main motor (2) links to each other with main drive roll (13) by belt, select product for use from frequency converter (6) with closed loop technology controlling and process function, the optional German VLT2800 of Danfoss AS series or VLT5000 Series Frequency Converter, link to each other with volume heart drive motor (7) from frequency converter (6), thin film disk (5) is fixed on the swelling winding reel (8) by expansion mechanism, guide rail (11) and 4 stationary rolls (3) are fixedly mounted on the substrate, dancer (10) is fixed on the slide block (12), draw runner on the slide block (12) is entrenched in the chute of guide rail (11), displacement detector (4) is selected high precision for use, the product of fast-response, can select for use Germany to execute the OD series displacement detector that gram photoelectricity company produces, be installed in the top of slide block (12), detect the displacement that slide block (12) moves up and down, displacement detector (4) and be electrically connected from frequency converter (6), film (14) is drawn from thin film disk (5), respectively around break-in roller (9), stationary roll (3), on dancer (10) and the main drive roll (13).The tension force of 6 films equals the weight sum of dancer (10) and slide block (12), by adjusting the weight of slide block (12) and dancer (10), makes the tension force of film (14) moderate, is unlikely tensile deformation.
Speed synchronization control process: at first set from frequency converter (6) parameter, mode is made as the closed loop technology controlling and process.The relative position of adjustment slide block (12) and displacement detector (4), this moment, displacement detector (4) output current value A gave from frequency converter (6), made from frequency converter (6) to be in the transformation point that heart drive motor (7) is rolled up in startup soon.
Start the machine, the speed-regulating potentiometer of rotation primary transducer (1) quickens main motor (2), the tissue ahead running, the film of main drive roll (13) pulling simultaneously quickens operation, and film (14) pulling dancer (10) makes slide block (12) move up along guide rail (11).Slide block (12) diminishes with the displacement of displacement detector (4); the current output value A1 of displacement detector (4) becomes big (A1 is greater than A); the A1 feedback inputs to from frequency converter (6); by the closed loop technology controlling and process; driving volume heart drive motor (7) from frequency converter (6) quickens to rotate; the big more volume heart of A1 value drive motor (7) acceleration/accel is big more; thin film disk (5) quickens to move back to put film (14); when moving back the linear velocity of putting thin film disk (5) greater than the linear velocity of main drive roll (13), slide block (12) slowly falls back to the position of setting when shutting down.The linear velocity of at this moment moving back the linear velocity of putting thin film disk (5) and main drive roll (13) is synchronous.
The speed-regulating potentiometer of rotation primary transducer (1), make main motor reduction of speed, the linear velocity of main drive roll (13) descends, and when moving back the linear velocity of putting thin film disk (5) greater than the linear velocity of main drive roll (13), slide block (12) by gravity moves down along guide rail (11).It is big that the displacement of slide block (12) and displacement detector (4) becomes, the current output value A2 of displacement detector (4) diminish (A2 is less than A).The A2 feedback inputs to from frequency converter (6); by the closed loop technology controlling and process; driving volume heart drive motor (7) deceleration from frequency converter (6) rotates; rouleau heart drive motor (7) negative acceleration is big more more for the A2 value; thin film disk (5) moves back that to put film (14) slack-off; when moving back the linear velocity of putting thin film disk (5) less than the linear velocity of main drive roll (13), slide block (12) slowly rises to the position of setting when shutting down.The linear velocity of at this moment moving back the linear velocity of putting thin film disk (5) and main drive roll (13) is synchronous.
