Detailed description of the invention:
Embodiment, is shown in as shown in Figures 1 to 3, a kind of reel adjusting device of the winding stand for wide format printer, comprise support body 1, be hinged with deflector roll 2 between two support bars 11 of described support body 1, the bottom of support body 1 is fixed with sliding bar 3, and roller bracing frame 4 and bogie 5 are all located on sliding bar 3;
Described bogie 5 comprises lower sleeve connecting portion 51 and is connected housing section 53 with the upper motor that the housing end plug 52 that lower sleeve connecting portion 51 top forms is fixed with, lower sleeve connecting portion 51 is located in sliding bar 3, servomotor 6 is provided with in upper motor connection housing section 53, output shaft 61 sleeve of the front end of servomotor 6 is in the ladder hole of housing end plug 52 and stretch out ladder hole, it is inserted with spring 62 successively, locating stop piece 68, be fixed with elastic-friction sheet 63 and be inserted with circular moving block 64, the macropore of ladder hole is near the end of the output shaft 61 of front end, spring 62, elastic-friction sheet 63 and locating stop piece 68 are all in the macropore of ladder hole, the end face of the output shaft 61 of front end is bolted with gland 65, gland 65 is pressed against on moving block 64, moving block 64 is pressed against on elastic-friction sheet 63, spring 62 one end is put forth effort on the bottom face of the macropore of the ladder hole of housing end plug 52, the other end is put forth effort on locating stop piece 68, locating stop piece 68 is pressed against on elastic-friction sheet 63, the output shaft 61 of the rear end of servomotor 6 stretches out the end plate of motor connection housing section 53, it is inserted with elastic washer 66 and is bolted with hold-down nut 67, between the end plate that elastic washer 66 is clamped in upper motor connection housing section 53 and hold-down nut 67.
The lower sleeve portion 42 that the bottom that described roller bracing frame 4 comprises connecting portion 41 and upper connecting portion 41 forms, lower sleeve portion 42 and the equal sleeve of lower sleeve connecting portion 51 are in sliding bar 3, the sidewall of lower sleeve portion 42 and lower sleeve connecting portion 51 is all bolted with hold-down bolt 7, the side wall and pressure that the top, bar portion of two hold-down bolts 7 is each passed through lower sleeve portion 42 and lower sleeve connecting portion 51 leans against on sliding bar 3, the inner side end of upper connecting portion 41 is hinged with circular protruding block 43, the end face that moving block 64 is relative with protruding block 43 forms circular protrusions 641, circular protrusions 641 is identical with protruding block 43 size, the center line of circular protrusions 641 and protruding block 43 on the same line, and parallel with horizontal plane, circular protrusions 641 and the annular sidewall of protruding block 43 all form straight knurling, straight knurling improves roller 10 inwall with circular protrusions 641, the frictional force of the annular sidewall of protruding block 43, make the two ends sleeve of roller 10 and holding in circular protrusions 641 with protruding block 43.
Operation principle: when installing roller 10, first the hold-down bolt 7 of roller bracing frame 4 is tightened, make it fix, then by roller 10 one end sleeve and holding in the protruding block 43 of roller bracing frame 4, other end sleeve be placed in the circular protrusions 641 that the moving block 64 of bogie 5 forms, then the hold-down bolt 7 on bogie 5 is tightened, the top, bar portion of hold-down bolt 7 is pressed against sliding bar 3 completes fixing.
Then, by regulating the hold-down nut 67 on the output shaft 61 of the rear end of servomotor 6, servomotor 6 is connected in housing section 53 at upper motor move axially, when needing to increase elastic-friction sheet 63 with the frictional force that moving block 64 is middle, as long as tighten hold-down nut 67, servomotor 6 is moved backward, such spring 62 compresses, spring 62 is made to increase thrust to locating stop piece 68, locating stop piece 68 increases the pressure to elastic-friction sheet 63, frictional force between elastic-friction sheet 63 and moving block 64 is increased, thus when the output shaft 61 of servomotor 6 is rotated, its moving block 64 synchronous axial system, as long as otherwise hold-down nut 67 is unscrewed.Wherein elastic-friction sheet 63 is silicon rubber, and it is that elasticity holding is on output shaft 61.
When roller 10 runs, it is when the papery reeled or film material thickness increase, the rotating speed of roller 10 will slow down, and now servomotor 6 is also keeping original speed to rotate, the two ends sleeve of roller 10 holding are in circular protrusions 641 with protruding block 43, and elastic-friction sheet 63 is pressed against on moving block 64 and drives moving block 64 to rotate by frictional force, skidding will be produced between such elastic-friction sheet 63 and moving block 64, to ensure that servomotor 6 normally runs, and roller 10 rotating speed reduces, meet winding needs.
