By using above-mentioned technical proposal, because the length of adjusting lever is constant, i.e. the base length of triangle is constant, when another
When outer two length of sides reduce, the angle of drift angle becomes big, when adjusting lever is fixed on the upper end of bar hole, left clamping plate and right clamping plate
Angle reaches maximum, and when adjusting lever is fixed on the lower end of bar hole, left clamping plate reaches minimum with the angle of right clamping plate;Adjust
After angle, adjusting lever is fixed on by left clamping plate and right Boards wall by the cooperation of fastening bolt and nut.
Further, the adjusting means includes being arranged at roller below left clamping plate and right clamping plate, is arranged under roller
The slide rail and the locking mechanism for fixed idler whell of side.
By using above-mentioned technical proposal, it is necessary to adjust in the angle between left clamping plate and right clamping plate, locking mechanism is untied,
Enable that roller is moved along slide rail, again locked roller by locking mechanism after adjusting angle.
Further, the locking mechanism includes the fixture block with the slide rail clamping, and each roller is correspondingly provided with two
Fixture block.
By using above-mentioned technical proposal, roller is fixed between two fixture blocks, can effectively prevent roller in slide rail
It is upper to relatively move.
Further, the traction component includes the axis of traction being connected with the Power Component and is led parallel to described
Draw the carry-over pinch rolls of axle setting, the axis of traction is with carry-over pinch rolls each parallel to the deflector roll.
By using above-mentioned technical proposal, Power Component drives axis of traction to rotate, and film is carried out under the drive of axis of traction
Operating so that inflation film manufacturing machine can run well;Carry-over pinch rolls can play a part of to flatten film.
Further, the Power Component includes motor.
Compared with prior art, the utility model has the advantages that:Rotate screwed pipe adjustment fixed block relative high with ground
Degree, or change the relative altitude on adjusting lever and ground, or directly change pushing rolling wheels come change left clamping plate and right clamping plate it
Between angle, so as to reach adapt to different performance film purpose so that inflation film manufacturing machine has more versatility.
