Description

Novel ooze filter membrane cutting and carry device

Technical Field

The process of preparing the small membrane is generally to remove the protective film by hand and then to cut the diafiltration film roll to obtain the small membrane.

The modes of cutting the infiltration membrane roll membrane comprise full-manual cutting and semi-automatic cutting.

For full-manual cutting, an operator is required to tear the protective film, cut a 300mm (width) × 30m (length) roll of diafiltration film into 10mm (width) × 300mm (length) strips, and then manually cut the strips to obtain 30 10mm × 10mm small films. The cutting mode has the advantages of low production efficiency, high labor intensity, time and labor waste, high production cost and lower yield.

Although partial human resources are liberated by the cutting mode, the requirement of automatically cutting the small film is still not met, the production efficiency is higher than that of full-manual cutting, the labor intensity of workers is still higher, the production cost is still maintained at a certain level, and the yield is basically the same as that of full-manual cutting.

In some embodiments, the sixth driving assembly 604 is a driving motor, and an output end of the sixth driving assembly is in driving connection with the third transmission element 603, and is configured to drive the third transmission element 603 to rotate, so that the third transmission element 603 carries the protection film 800 to rotate, and the protection film 800 forms a protection film roll.

The fourth transport mechanism 600 further comprises a fourth transmission element (not shown) for sleeving the diafiltration film web on the fourth transmission element.

For the fourth conveying mechanism 600, the working steps are as follows: the protective film 800 attached to the diafiltration film 700 is peeled off, and one end of the protective film 800 is attached to the third driving member 603 after passing through the second driving member 602; the sixth driving assembly 604 drives the third transmission element 603 to rotate, so that the protective film 800 is continuously separated from the diafiltration film 700, and the protective film 800 forms a protective film roll on the third transmission element 603 for subsequent recovery; the separated diafiltration membrane 700 is transported to the next process for use, i.e. is sucked by the first suction element 102 of the first transport mechanism 100 for use in the subsequent process.

The specific implementation process of the novel infiltration membrane cutting and conveying device of the embodiment is as follows:

the first suction element 102 sucks the percolating membrane 700 in a first preset position (the front end corner of the percolating membrane has been cut off);

the first driving component 104 drives the second suction component 103 to move towards the first suction component 102, and when the second suction component 103 moves to a second preset position, the second suction component 103 adsorbs the percolation membrane 700 and releases the adsorption of the percolation membrane 700 by the first suction component 102;

the first driving assembly 104 drives the second suction element 103 to move a small film size distance (30mm) toward the second suction assembly 202;

the second suction assembly 202 and the first suction element 102 simultaneously adsorb the diafiltration membrane 700 and desorb the diafiltration membrane 700 from the second suction element 103;

while the third driving element 303 drives the first cutting element 302 to move transversely, the fourth driving element 304 drives the first cutting element 302 to cut the diafiltration membrane 700, so that the diafiltration membrane adsorbed by the second adsorption module 202 is cut into strips and separated from the diafiltration membrane 700 adsorbed by the first adsorption element 102;

the second driving assembly 204 drives the second suction assembly 504 to move to a third preset position, and the fourth driving assembly 405 drives the second cutting assembly to cut the strip film, so that the strip film sucked by the second suction assembly 202 is cut into small films; meanwhile, the third driving element 303 drives the first cutting element 302 to move to the initial position, the first driving assembly 104 drives the second suction element 103 to move to the second preset position, and the sixth driving assembly 604 of the fourth conveying mechanism 600 drives the third transmission element 603 to rotate so as to drive the protective film to rotate by a distance of a small film size;

the second driving assembly 204 drives the second suction assembly 504 to move to a fourth preset position, the fifth driving assembly 503 drives the third suction assembly 502 to move downwards, the third suction assembly 502 sucks the small film and releases the sucking of the second suction assembly 202 to the small film, and the fifth driving assembly 503 drives the third suction assembly 502 to move upwards for the use of the subsequent process;

the second driving component 204 drives the second suction component 202 to move to a third preset position;

repeating the above steps until the cutting of the diafiltration membrane is completed.

By the novel filtration membrane cutting and conveying device, full-automatic cutting of strip membranes and small membranes can be performed on the filtration membrane, and the cutting efficiency is improved; the first absorption assembly, the second absorption assembly and the third absorption assembly can be used for accurately absorbing, desorbing and positioning the osmosis membrane, the strip membrane and the small membrane; in the moving process of the second suction assembly, the adsorbed strip film can be cut into small films by the second cutting mechanism without additionally arranging a transfer device, so that the cutting efficiency of the small films is improved, and the production cost is reduced; the second suction element only moves one small-membrane-size distance each time, secondary positioning of the percolation membrane is not needed, membrane material cutting time is reduced, strip membrane cutting efficiency is improved, and equipment cost is reduced; at least 300 pieces of the small membranes can be cut every minute, so that the infiltration membrane and the protective membrane are automatically separated, the infiltration membrane, the strip membrane and the small membranes are automatically adsorbed and desorbed, and the infiltration membrane, the strip membrane and the small membranes are automatically cut, thereby greatly improving the production efficiency, reducing the production cost and ensuring the basic consistency of the small membrane specifications.

The above description is only an example of the preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and those skilled in the art should be able to realize the equivalent alternatives and obvious variations of the present invention.
