9. a kind of lever film automatic detection device according to claim 1, which is characterized in that the inspection of the detection device
Survey process is as follows:
Step 1: film is placed on side live-roller (2), is passed using the other side is wound into after two guide rollers (131)
Film is worn into two idler wheels (25) in material hole (251) in guide rod (14) surface sliding guide sleeve (28) in dynamic roller (2) surface
Between, rotate fastening bolt (27), will test between plate (15) and guide rod (14) fixation, rotating boss bolt (18), adjust to
Boss bolt (18) is in contact at the top of lever compression bar (20) close to switch (19), rotating boss nut (17), by boss bolt
(18) it is fixed；
Step 2: drive shaft (3) cooperates rolling bearing (4) rotation of two sides, and drive shaft (3) drives live-roller (2) rotation retracting
Film, when the film thickness between two idler wheels (25) is normal, spring (22) is in tensional state, tenses bearing block (23),
And then lever compression bar (20) is driven to approach switch (19) for bearing block (23) and boss bolt (18) bottom connection touches, when two
When thickened film thickness between idler wheel (25), the idler wheel (25) of the upward upper end of film, the idler wheel (25) of upper end drives dynamic
Arm of force bearing block (23) is around positioning bearing (24) rotation as fulcrum, and then bearing block (23) drives the lever as resistance arm
Compression bar (20) starts turning, and spring (22) further stretches, close to switch (19) and boss bolt (18) on lever compression bar (20)
Bottom does not contact, and generates signal close to switch (19) at this time and signal is passed to single-chip microcontroller by conducting wire, single-chip microcontroller control after
Electric appliance opens the second motor (35), and the second motor (35) output shaft drives side gear (34) rotation, two side gear (34) cooperations
The groove face of lifter plate (31) two sides rotates, and lifter plate (31) prolongs positive stop strip (32) decline, and lifter plate (31) drives the company of bottom
Extension bar (36) declines, and the cutting line (37) between connecting rod (36) cuts film, completes film thickness detection.
