[0032] The left and right sides of transmission roller 1 are connected with sliding block 14, and the staff adjusts the up-and-down sliding of sliding block 14 in sliding slot 13 through the drive mechanism, so that the up-and-down height of transmission roller 1 can be adjusted, and after the two side support frames 12 are installed on the film processing equipment rack, the transmission roller 1 can be installed on the film processing equipment, and when the film passes through the lower side of the transmission roller 1, the puncture needle 11 on the outer surface of the transmission roller 1 can perform the punching work on the film surface.

[0033] During the use of transmission roller 1, the lock handle 26 is loosened, the limiting of limiting block 21 is cancelled, at this time, the staff adjusts the height of limiting block 21 by sliding upward through the first screw rod 25, adjusts the position of sliding block 14, ensures that the stop block 23 is located below the limiting block 21, adjusts the stop block 23 to be located below the sliding block 14, ensures that the stop block 23 is in close contact with the lower surface of the sliding block 14, and then the lock handle 26 is tightened, the lock handle 26 is in close contact with the outer surface of the support frame 12, so as to ensure that the position of the limiting block 21 is in a fixed state, and the limiting block 21 will not slide.

[0034] The staff can adjust the height of the transmission roller 1 through the driving mechanism. When the transmission roller 1 is maintained and the height is adjusted, the staff can put the block 23 into the groove 22 through the trigger mechanism, so that the block 23 does not limit the slider 14. At this time, the staff can freely adjust the height of the transmission roller 1. The staff can overhaul and maintain the transmission roller 1. When it is necessary to drive the transmission roller 1 to reset and adjust to the original position, the height of the transmission roller 1 can be adjusted upward, and the slider 14 is kept on the upper side of the limiting block 21. At this time, the staff puts the block 23 out of the groove 22 through the trigger mechanism, and keeps part of the block 23 on the lower side of the slider 14. At this time, the staff can adjust the height of the transmission roller 1 downward until the slider 14 is tightly dropped on the upper side of the block 23. In this way, the staff can quickly complete the reset of the transmission roller 1 without repeatedly adjusting the height of the transmission roller 1.

[0035] The trigger mechanism comprises a threaded hole 3 arranged on the inner wall of the groove 22, the threaded hole 3 penetrates through the inner wall of the first screw rod 25 on one side, and the block 23 is rotatably connected with a second screw rod 31 on one side. The second screw rod 31 is assembled with a tightening piece 32 through the threaded hole 3.

[0036] The second screw rod 31 is threadedly connected with the threaded hole 3, so that when the second screw rod 31 rotates in two directions respectively, the second screw rod 31 can slide left and right in the threaded hole 3. Since the second screw rod 31 is connected with the block 23, when the second screw rod 31 slides left and right, the block 23 can slide left and right, so that the purpose of freely adjusting the position of the block 23 can be achieved.

[0037] The limiting block 21 is provided with a mounting groove 33 on the left and right sides, and a top block 34 is slidably assembled in each of the two mounting grooves 33. A plurality of clamping teeth 35 are arranged on the side away from each other of the two top blocks 34, and a rack 36 matched with the plurality of clamping teeth 35 is arranged on the inner wall of the sliding groove 13.

[0038] When the block 23 extends out of the groove 22, the two top blocks 34 simultaneously move to the side of the extending mounting groove 33 until the plurality of clamping teeth 35 on the outer side of the top block 34 engages with the rack 36. This design can ensure the stability of the limiting block 21 and prevent the limiting block 21 from sliding downward due to the downward impact of the slider 14. When it is necessary to adjust the position of the limiting block 21, the block 23 is put into the groove 22, and the position of the limiting block 21 can be freely adjusted.

[0039] The inner wall of the mounting groove 33 is provided with two telescopic rods 4, one end of each of the two telescopic rods 4 is connected with the top block 34, and a spring 41 is sleeved outside each of the two telescopic rods 4. The top block 34 and the block 23 are matched with the connecting assembly.

[0040] When the stopper 23 extends out of the groove 22, the pulling force on the two top blocks 34 is cancelled through the connecting assembly, and the top blocks 34 are pushed to extend out of the mounting groove 33 under the extension of the spring 41, so that the plurality of clamping teeth 35 are connected with the rack 36; when the stopper 23 is retracted into the groove 22, the top blocks 34 are retracted into the mounting groove 33 through the connecting assembly, and the telescopic rod 4 and the spring 41 are in a compressed state.
