The working principle of the invention is as follows:

in the moving process of the bottom film 41 and the silica gel piece 42, the moving speeds of the bottom film 41 and the silica gel piece 42 are different, the moving speed of the bottom film 41 is larger than the moving speed of the silica gel piece 42, the silica gel piece 42 moves intermittently at a constant speed through a front device, the bottom film 41 is driven to move intermittently at a constant speed through a rear winding device, and the bottom film 41 is wound and penetrated from the lower part of the mounting groove 11;

firstly, the height of a limiting column 332 is adjusted, the distance between a first pressing block 33 and a pressing plate 35 is equal to the distance between the base 1 and the pressing plate 35 respectively, then when the silica gel sheet 42 moves to a proper position, the lifter 22 drives the lifting plate 3 to descend, the lifting plate 3 enables the first pressing block 33 and the pressing plate 35 to be in contact with the silica gel sheet 42 respectively through a spring telescopic piece 32, the first pressing block 33 and the pressing plate 35 press the silica gel sheet 42 through the spring telescopic piece 32, the cutter 31 continuously moves downwards under the action of the lifter 22, at the moment, the distance between the elastic adjusting piece 36 and the pressing plate 35 is shortened, the elastic adjusting piece 36 is compressed under the action of force, meanwhile, the elastic adjusting piece 36 releases pressure to enable the pressing plate 35 to move towards the rear of the base 1, the pressing plate 35 pulls the silica gel sheet 42, at the moment, the elastic adjusting piece 36 only releases partial pressure to enable the silica gel sheet 42 to be in a tensioning state, the cutter 31 is convenient to cut off the silica gel sheet 42 better, and a rack 352 on the sliding plate 351 moves along with the pressing plate 35, a spring sheet 371 on the positioning plate 37 deforms under the action of the rack 352 to enable the rack 352 to move downwards, and the rack 352 is not blocked by the movement of the spring sheet 371;

finally, the cutter 31 descends to contact with the rotating roller 12 to cut off the silica gel piece 42, so that the silica gel piece 42 is formed into a strip shape and is arranged on the bottom film 41 at intervals, the silica gel piece 42 after the cut-off of the cutter 31 is pressed down by the first pressing block 33 and the pressing plate 35 due to the viscosity of the cross section of the silica gel piece 42, the silica gel piece 42 is not stuck on the cutter 31 to influence the subsequent cutting of the cutter 31, the cut-off silica gel piece 42 is in a tensioning state, and the cut-off silica gel piece 42 has partial viscosity stuck on the rotating roller 12, and the residual pressure of the elastic adjusting piece 36 is released to drive the pressing plate 35 to continuously move so as to drive the cut-off silica gel piece 42 to move to bring the silica gel piece 42 from the rotating roller 12, so that the situation that the cross section of the cut-off silica gel piece 42 is stuck on the rotating roller 12 can not be moved is solved;

when the lifter 22 ascends, the lifter plate 3 drives the pressing plate 35 to move upwards through the elastic adjusting piece 36, at this time, the sliding plate 351 is limited by the cooperation between the elastic piece 371 and the rack 352, the sliding plate 351 cannot move leftwards, so that the silicon sheet 42 is prevented from being pulled leftwards by the pressing plate 35, the pressing plate 35 moves upwards while the compression spring 38 releases pressure, so that the elastic piece 371 and the rack 352 are separated, at this time, the pressing plate 35 is also separated from the silicon sheet 42 in the upward moving process, and therefore the position of the silicon sheet 42 is prevented from being influenced in the resetting process of the pressing plate 35.
