In this embodiment, the elastic member i 14 and the elastic member ii 23 are both springs.
The work table 2 is located the basin 3, contains water in the basin 3, and the liquid level is less than the upper surface of work table 2, and the diapire of basin 3 bonds and has inflatable air bag 25, and inflatable air bag 25 intercommunication has gas tube 26 and bleeder 27, and the one end that inflatable tube 26 kept away from inflatable air bag 25 is connected with pump 28, installs bleed valve 29 on the bleeder 27.
The specific implementation process is as follows: firstly, the staff holds handle 9, rotates wind-up roll 5 for wind-up roll 5 clockwise rotates, winds up non-woven fabrics 10 on wind-up roll 5, and simultaneously, release roll 4 anticlockwise rotates, releases clean non-woven fabrics 10 (initially, if non-woven fabrics 10 on workstation 2 is clean and has no filth, can not necessarily rotate wind-up roll 5 and replace non-woven fabrics 10 on workstation 2), until clean non-woven fabrics 10 paves workstation 2. In-process, because tensioning roller 7 can move up and down in vertical direction, consequently tensioning roller 7 can make non-woven fabrics 10 be in the state of straining all the time, and because the distance between 6 bottoms of guide roll and workstation 2 equals the thickness of non-woven fabrics 10, therefore non-woven fabrics 10 can laminate at the upper surface of workstation 2, does not influence the thickness of membrane when making the membrane. In addition, because the wind-up roll 5 can only rotate clockwise, and the release roll 4 receives great frictional resistance in the rotation process, therefore, after the staff stops rotating the wind-up roll 5, the non-woven fabrics 10 are in a tense state, thereby ensuring that the film body with the preset thickness is smoothly prepared.
Then, the screw thread adjusting lever 24 is rotated to move the screw thread adjusting lever 24 downward, the slide plate 21 is pushed to slide downward, the film scraping blade 22 on the slide plate 21 is extended out of the groove 20, and the distance between the film scraping blade 22 and the non-woven fabric 10 is adjusted by rotating the screw thread adjusting lever 24 so that the distance is equal to the predetermined thickness of the film body.
Then, the film-forming liquid is poured onto the non-woven fabric 10 on the workbench 2, the telescopic cylinder 17 is started, the output end of the telescopic cylinder 17 drives the film-scraping seat 18 to reciprocate horizontally, and then the film-forming liquid is uniformly spread on the non-woven fabric 10 by the film-scraping knife 22, so that film forming is completed. After the membrane is formed, the telescopic cylinder 17 is closed, the membrane scraping seat 18 is still, a worker rotates the thread adjusting rod 24, so that the thread adjusting rod 24 moves upwards, the sliding plate 21 slides upwards under the action of the elastic piece II 23 to reset, and then the membrane scraping knife 22 moves upwards to be far away from the non-woven fabric 10.
Then, the worker starts the inflator 28, the inflator 28 inflates the inflatable air bag 25 through the inflation tube 26, the inflatable air bag 25 gradually expands, and the liquid level in the water tank 3 gradually rises until the non-woven fabric 10 and the film body on the non-woven fabric 10 are completely submerged in the water, so that the film body is solidified in the water. After the film body is solidified, the air release valve 29 on the air release pipe 27 is opened, the air in the inflatable air bag 25 is discharged through the air release pipe 27, the volume of the inflatable air bag 25 is reduced, the liquid level in the water tank 3 is lowered, and the non-woven fabric 10, the film body and the workbench 2 are exposed. Then, the worker dries the film body by using a blower or other means, and simultaneously dries the nonwoven fabric 10, and cuts the nonwoven fabric 10 having the film body on the surface thereof after drying (the width of the nonwoven fabric 10 having the film body on the surface thereof is smaller than the width of the nonwoven fabric 10).
Finally, the staff holds handle 9, clockwise rotation wind-up roll 5, with old non-woven fabrics 10 rolling to wind-up roll 5 on, release 4 anticlockwise rotations of roller release simultaneously and release new, clean non-woven fabrics 10, until clean non-woven fabrics 10 flatly lays on workstation 2 completely, can carry out the membrane of next time, easy operation, convenience improve membrane efficiency.
