Description

Technical Field

[0001] The invention relates to the technical field of reverse osmosis membrane unwinding, in particular to a reverse osmosis membrane unwinding docking and fixing mechanism. Background Art

[0002] Reverse osmosis is a membrane separation technology that uses pressure as a driving force by means of the function of selective permeable (semi-permeable) membranes. The semi-permeable membrane that realizes this process is called a reverse osmosis membrane. The reverse osmosis membrane unwinding equipment is a commonly used equipment in reverse osmosis membrane processing. During the unwinding process of the reverse osmosis membrane roll, the reverse osmosis membrane roll is separated into release paper and reverse osmosis membrane.

[0003] The existing reverse osmosis membrane unwinding equipment usually adopts manual replacement when replacing the reverse osmosis membrane roll. However, during the replacement process, the release paper and the reverse osmosis membrane of the two reverse osmosis membrane rolls need to be manually connected, and this process requires stopping the operation of the unwinding equipment, which will affect the efficiency of the reverse osmosis membrane unwinding.

By setting the slider 2210, the slide groove 2230, the multi-section telescopic rod 2211 and the first spring 2212 for coordinated use, when the moving rod 2204 moves to the inner cavity of the concave bar 2207, the first spring 2212 will not be deformed by force.

By setting the cavity 2213, the adjusting plate 2214 and the third electric telescopic rod 2215 for use together, the adjusting plate 2214 can be adjusted. The height of 214 is adjusted so that the third electric telescopic rod 2215 drives the T-shaped block 2216 to be stuck in the inner cavity of the T-shaped slot 2217 of one of the moving rods 2204, so that when the third electric telescopic rod 2215 is extended, it can drive the moving rod 2204 to move horizontally.

When the moving rod 2204 moves in the opposite direction, the force deformation of the second spring 2229 will drive the first telescopic rod 2227 to reset. The second spring 2229 adopts weak elasticity to prevent the flexible hose 2220 from being squeezed by the connecting ring 2228, and the transverse hole 2202 is connected to the cavity 2213.

[0045] The specific implementation of this embodiment is as follows: since there are two unwinding shafts 13, when unwinding the reverse osmosis membrane roll on one of the unwinding shafts 13, a new reverse osmosis membrane roll is installed on the surface of the other unwinding shaft 13 for standby, and the initial end of the new reverse osmosis membrane roll is moved to the bottom of the corresponding traction plate 2205, and the initial end of the reverse osmosis membrane roll is adsorbed by the traction plate 2205. When docking, the height of the adjustment plate 2214 is adjusted so that the third electric telescopic rod 2215 drives the T-shaped block 2216 to be stuck in the inner cavity of the T-shaped groove 2217 of one of the moving rods 2204, so that the third electric telescopic rod 2215 can drive the moving rod 2204 to move horizontally when it is extended. When the moving rod 2204 moves to the inner cavity of the concave strip 2207, the T-shaped grooves 2217 on the moving rod 2204 and the concave strip 2207 are aligned. At this time, the traction plate 2205 drives the initial end of the reverse osmosis membrane roll to move above the suction table 2114, and then the external control switch is used to start The electric push rod 2209 is driven, so that the concave strip 2207 slides in the inner cavity of the vertical hole 2203. When the concave strip 2207 moves downward, the T-shaped block 2216 will be separated from the T-shaped slot 2217, so that the initial end of the reverse osmosis membrane roll contacts the top of the suction table 2114, and then the initial end of the reverse osmosis membrane roll is fixed by the suction table 2114. When the closing plate 2221 needs to be moved, the fourth electric telescopic rod 2224 is started by the external control switch. The closing plate 2221 is moved, and the movement of the closing plate 2221 drives the through hole 2222 to communicate with one of the flexible hoses 2220, thereby avoiding the effect of the two traction plates 2205 being adsorbed at the same time, and by setting the sealing plate 2226 and the sliding rod 2225, when the closing plate 2221 moves, it will drive the sliding rod 2225 to move, thereby driving the adjustment plate 2214 to move up and down, and the sealing plate 2226 is used to ensure the seal between the sliding rod 2225 and the air collecting box 2219.

By setting a cutting mechanism 3, the tape is guided by the guide roller 303, so that the side of the hollow arc plate 304 and the hollow long plate 305 close to the fixed rod 306 contacts the tape. When the adsorption roller 2106 and the adsorption shell 2110 move to the inner cavity of the mounting shell 301, the fifth electric telescopic rod 307 is started by an external control switch, so that the annular cutter 308 cuts the tape and passes through the inner cavity of the hollow arc plate 304 and the hollow long plate 305 respectively, so that the smooth surface of the tape contacts the adsorption end of the adsorption shell 2110 and the adsorption roller 2106, thereby achieving the effect of adsorbing the cut tape.
