Description

Technical Field

[0001] The invention relates to the field of masterbatches, and in particular to a filter screen maintenance and cleaning device for drying and filtering masterbatches. Background Art

[0002] The color silk factory uses hot air to heat and dry the masterbatch barrel regularly, and then releases the masterbatch from the discharge port, and then uses it after manual dispersion and screening. A stirring paddle is installed in the drying barrel, which is driven by a motor and has at least one layer of stirring blades. A conical filter is installed at the bottom of the drying barrel to stir the masterbatch in the barrel during drying, which enhances the fluidity of the air, makes the masterbatch dry evenly, and eliminates the occurrence of agglomeration. The conical filter automatically screens out abnormal slices that exceed the normal particle size of the masterbatch slices.

[0003] The masterbatch is softened after being heated, and the stirring of the stirring paddle causes the mesh of the conical filter to be often adhered to the heated masterbatch, resulting in poor screening effect.

[0037] The outer surfaces of the first needle roller 3013 and the second needle roller 409 are both provided with thorns, and the thorns are provided with barbs, which are conducive to pulling out the bonded masterbatch.

[0038] The first hook 3017 and the second hook 4013 are both provided with barbs, which are conducive to cleaning and collecting the masterbatch on the first needle roller 3013 and the second needle roller 409.

[0039] Before work, the staff will place the wider end of the conical filter on the support ring 205, squeeze and fix the conical filter under the action of the annular elastic rubber strip 206, and then control and start the two first electric slide rails 202 to drive the two first electric sliders 203 to move to the right. The two first electric sliders 203 drive the support ring 205 and the fixed conical filter to move through the two second mounting plates 204 until the conical filter is located in the heating box 207, and then start the heating box 207 to heat the masterbatch particles bonded to the conical filter, so that the masterbatch is softened and stretchable but not melted; then continue to control the movement of the conical filter until the conical filter is located below the third mounting plate 304, control the second electric slide rail 302 to start The second electric slider 303 and its associated parts and the fourth electric slide rail 4011 and its associated parts move toward each other until the first needle roller 3013 contacts the outer surface of the conical filter screen and the second needle roller 409 contacts the inner surface of the conical filter screen. Then, based on the view from top to bottom, the first motor 305 and the second motor 405 are controlled to start at the same time, so that the first spur gear 306 rotates counterclockwise, and the transmission rod 406 rotates clockwise. The first spur gear 306 drives the second spur gear 307 to rotate clockwise around the first transmission shaft 308. The first transmission shaft 308 drives the twelfth mounting plate 3019 and its associated parts to rotate clockwise. When the first needle roller 3013 rotates, it drives the second bevel gear 3014 to rotate on the first bevel gear The second bevel gear 3014 rotates clockwise, and the second bevel gear 3014 drives the first needle roller 3013 to rotate, so that the first needle roller 3013 rotates clockwise while following the rotation of the twelfth mounting plate 3019. At the same time, the transmission rod 406 drives the seventh mounting plate 407 and the parts connected thereto to rotate clockwise. When the second needle roller 409 rotates, it drives the third bevel gear 4010 to roll on the inner bevel gear 403, so that the third bevel gear 4010 rotates. The rotation of the third bevel gear 4010 drives the second needle roller 409 to rotate, so that the second needle roller 409 rotates while following the rotation of the transmission rod 406. In this way, the first needle roller 3013 and the second needle roller 409 rotate simultaneously. The first needle roller 3013 and the second needle roller 409 rotate clockwise, and the first needle roller 3013 and the second needle roller 409 rotate, and the thorns on the outer surface are inserted into the mesh of the conical filter screen. If the mesh is adhered with masterbatch, the masterbatch has been heated and softened, so the thorns will be inserted into the masterbatch, and then the masterbatch will be stretched by continuing to rotate. After stretching, the first motor 305 and the second motor 405 are controlled to stop, so that the first needle roller 3013 and the second needle roller 409 are no longer rotating, and then the two electric push rods 3011 are controlled to start and drive the cutter 3018 to move forward, and the cutter 3018 cuts the stretched masterbatch into two sections, and then the first motor 305 and the second motor 405 are continued to be controlled to start, so that a section of the masterbatch is driven to rotate by the first needle roller 3013.The other section is driven to rotate by the first needle roller 3013, so that the masterbatch is taken out from the mesh. The above operation is repeated to take out all the large pieces of masterbatch stuck on the conical filter screen. When the cutter 3018 cuts off the masterbatch, the third electric slide rail 3015 and the fourth electric slide rail 4011 are controlled to start at the same time to drive the third electric slider 3016 and the fifth electric slider 4012 to move. The third electric slider 3016 and the fifth electric slider 4012 drive the first hook 3017 and the second hook 4013 to move. The first hook 3017 and the second hook 4013 move to scrape the masterbatch on the first needle roller 3013 and the second needle roller 409 and leave it on their own The first hook 3017 and the second hook 4013 can be removed from the third electric slider 3016 and the fifth electric slider 4012. When there are many masterbatches on the first hook 3017 and the second hook 4013, they can be removed and then the masterbatches can be removed and reinstalled. When all the masterbatches adhered to the mesh of the conical filter are removed, the second electric slide rail 302 is controlled to start so that the second electric slide rail 303 and its associated parts and the fourth electric slide rail 4011 and its associated parts move in opposite directions, so that the associated parts are reset.

[0042] The outer surface of the conical cleaning block 5011 is provided with bristles for cleaning the inside of the filter.

[0043] After the large pieces of masterbatch stuck on the filter mesh are taken out, the two first electric slide rails 202 are controlled to start so that the conical filter continues to move, and moves to the point where the conical filter is directly above the conical cleaning block 5011 and stops. Then the two fifth electric slide rails 505 are controlled to drive the two sixth electric sliders 506 to move upward, and the two sixth electric sliders 506 drive the tenth mounting plate 507 and its associated parts to move upward until the conical cleaning block 5011 contacts the inner surface of the conical filter. Then the fourth motor 5010 is controlled to start and drive the conical cleaning block 5011 to rotate. The conical cleaning block 5011 rotates to clean the inner surface of the conical filter. At the same time, the bristles on the surface of the conical cleaning block 5011 can further dredge the mesh to remove the small pieces of masterbatch stuck on the mesh. The masterbatch is scraped off. In order to further improve the removal efficiency of small pieces of masterbatch, the third motor 502 is controlled to start and drive the ninth mounting plate 503 to rotate during the rotation of the conical cleaning block 5011. The ninth mounting plate 503 drives the nozzle 504 to rotate. During the rotation of the nozzle 504, the external air pump is started, so that high-pressure gas is sprayed from the nozzle 504 to each mesh of the conical filter screen, so that the bonded masterbatch is separated from the mesh, and the cleaned small pieces of masterbatch and dust impurities are collected in the annular collection barrel 508. After cleaning, the two fifth electric slide rails 505 are controlled to drive the two sixth electric slide blocks 506 to move downward and reset, so that the related parts can be reset. Finally, the conical filter screen can be removed from the annular elastic rubber strip 206 by the staff.
