Example 2
The embodiment provides a cam type gap coating device which comprises a machine frame 10, a steel roller 20 fixed on the machine frame, a back roller assembly 30 arranged on the machine frame 10 in a sliding mode, and a driving air cylinder 40 used for driving the back roller assembly 30 to abut against and be jointed with the steel roller 20. The backing roller assembly 30 includes a backing roller seat 32 slidably disposed on the frame 10, a backing roller 31 fixed on the backing roller seat 32, and a connecting seat 33 linked with the backing roller seat 32.
The connecting seat 33 is pushed by the action of the telescopic end of the driving cylinder 40, so that the back roll seat 32 which is linked with the connecting seat 33 is pushed, the back roll 31 abuts against the sheet to be coated on the steel roll 20, and the coating of the steel roll 20 is coated on the sheet.
Since the backing roller 31 performs the coating action by abutting against and engaging with the steel roller 20 by the pushing force of the driving cylinder 40, the pushing force of the driving cylinder 40 to the backing roller 31 will affect the coating quality.
In order to prevent the thin material from being clamped and unable to perform the coating action due to the overlarge thrust of the back roller 31 against the steel roller 20, as a further improvement of the technical scheme, the embodiment is different from embodiment 1 in that a limit block 41 is arranged at the connection position of the driving cylinder 40 and the connection seat 33.
The limiting block 41 is in a T shape, when the driving cylinder 40 pushes the connecting block 33 to the back roller 31 to reach the limit position, the lower part of the limiting block 41 abuts against the upper edge of the rack 10, the thrust of the driving cylinder 40 does not act on the connecting block 33 any longer, and the limiting block 41 abuts against the thrust of the driving cylinder 40. The limiting block 41 is arranged at the joint of the driving air cylinder 40 and the connecting seat 33, so that the connecting seat 33 and the backing roll seat 32 are limited in movement, and the phenomenon that the thrust of the driving air cylinder 40 is too large, so that the thrust of the backing roll 31 to the steel roll 20 is too large to influence the coating quality is prevented.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
