when a worker needs to feed materials in the nylon processing process, the worker only needs to directly pour the materials without dust removal into the feeding port 21, the materials fall under the action of gravity and finally contact with the dust-separation arc plate 23 in the feeding box 2, the dust-separation arc plate 23 rotates around the rotating shaft 22 under the action of gravity and impact, the rotating shaft 22 can drive other dust-separation arc plates 23 to rotate, the next dust-separation arc plate 23 is close to the feeding port 21 under rotation, the feeding port 21 is blocked by the last dust-separation arc plate 23, the situation that dust overflows due to the fact that dust is lifted up when the materials are poured into the feeding box 2 is prevented, the dust-separation arc plate 23 driven by the materials can move close to the bottom of the feeding box 2, the materials slide into the feeding box 2 from the dust-separation arc plate 23 along with the rotation of the dust-separation arc plate 23 around the rotating shaft 22 and are finally accumulated in the feeding box 2, the dust lifted up in the feeding box 2 is cleaned by the dust-removal assembly 3, the purpose of cleaning dust from materials is achieved, compared with the prior art, dust removal is firstly carried out in feeding, operation steps are reduced, meanwhile, elements such as a heating block and the like can be arranged in the feeding box 2, the purpose of drying the materials is achieved, finally, the motor is controlled to rotate through the controller, the motor rotates to drive the auger in the conveying pipe 1 to rotate, and finally, the materials are conveyed into the stirring tank through the auger to be stirred, so that the process of processing and feeding nylon is completed; when the dust removal arc board 23 rotates the top, the counter weight is scraped strip 5 and is slided to being close to pivot 22 under the effect of gravity, along with the rotation of dust removal arc board 23, counter weight is scraped strip 5 and is scraped in the inboard of dust removal arc board 23, scrape in-process and all scrape down to feeding box 2 with the inboard dust of dust removal arc board 23 and material, thereby avoid remaining dust or material on the dust removal arc board 23, one of them is in order to prevent to cause the material extravagant, two of them is for the accuracy that a plurality of materials added according to the proportion, guarantee that the material can both get into the agitator tank through conveying pipeline 1, the third is that prevent that material or dust from causing the influence to the use of dust removal arc board 23. The transmission rod 34 passes through the filter screen 41; the second gear 35 is driven the in-process and can drive the transfer line 34 to rotate, and the transfer line 34 rotates and can drive the extension to scrape the strip 6 and rotate to scrape the strip 6 through the extension and be close to the one side dust or the impurity rotation of feed box 2 with filter screen 41 and scrape down, dust or impurity are scraped the back and are discharged from charging chute 61, have reached the purpose of dredging filter screen 41, have improved filter effect of filter screen 41 greatly.
The dust-proof arc plate 23 drives the rotating shaft 22 to rotate under the action of gravity and impact force, the rotating shaft 22 drives the transmission shaft 31 to rotate, the transmission shaft 31 rotates to drive the first gear 32 to rotate, the first gear 32 rotates to drive the second gear 35 to rotate, the second gear 35 rotates to drive the fan 36 to rotate, the fan 36 rotates to enable air flow to enter from the feeding hole 21 of the feeding box 2 and then flow out from the air vent 33, and the air flow generated by the rotation of the dust-proof arc plate 23 drives dust to be discharged from the air vent 33, so that the dust lifted in the feeding box 2 by the materials is discharged; wherein, the fan 36 draws the external air flow from one of the air vents 33 into the feeding box 2, and then discharges the dust in the feeding box 2 along the other air vent; the dust-separation arc plates 23 are arranged to be arc-shaped, so that the dust-separation arc plates 23 can pocket more materials when the materials enter the feeding box 2, the dust-separation arc plates 23 can obtain larger kinetic energy, the gravitational potential energy and the power of the materials are converted into the kinetic energy of the dust-separation arc plates 23 driving the rotating shaft 22 to rotate, the rotating speed of the rotating shaft 22 is greatly increased, and the kinetic energy obtained by the fan 36 is larger; the larger the gear ratio of the first gear 32 to the second gear 35 is, the larger the gear ratio is, the more the first gear 32 rotates one circle, the more the second gear 35 can rotate many circles, so that the first gear 32 can drive the second gear 35 to rotate faster after rotating, so that the fan 36 can pass through the transmission rod 34 or a larger kinetic energy; wherein, fan 36 will draw the dust in the feed box 2 to the siphunculus 4 in from blow vent 33, thereby realize the filtration to the dust through filter screen 41 in the siphunculus 4, the staff can hold regularly and press frame 44, thereby make and press frame 44 to drive scraping strip 43 and slide in logical groove 42, scraping strip 43 and can scraping the side that is close to feed box 2 to filter screen 41 along leading to the gliding while of groove 42, thereby scrape down the dust on the filter screen 41 under scraping strip 43's scraping effect, the dust drops along logical groove 42 after being scraped at last and is collected by the collection frame.
For example, it is particularly important that, for example, in order to further bounce off dust, the surface of the rotating shaft 22 is provided with an elastic sheet, the other side of the elastic sheet is connected to the counterweight scraping strip 5, the elastic sheet is folded, and the original length of the expanded elastic sheet is smaller than the distance between the two opposite sides of the dust-separating arc plate 23, so that the counterweight scraping strip 5 tightens the elastic sheet when sliding to the side of the dust-separating arc plate 23 away from the rotating shaft 22, thereby dropping off the residual dust on the elastic sheet, and the elastic sheet provides a restoring force for the counterweight scraping strip 5 to return, so as to assist the counterweight scraping strip 5 to return when the counterweight scraping strip 5 rotates above the rotating shaft 22. The dust on the elastic sheet can be vibrated and loosened in the process of stretching the elastic sheet. For example, be provided with the magnet strip on the pivot 22, be provided with the iron sheet on the counter weight is scraped strip 5, when initial position, counter weight is scraped strip 5 and is in comparatively horizontally position with the magnet strip this moment, and counter weight is scraped strip 5 and is adsorbed in the magnet strip with the elastic sheet of centre gripping ruggedness, at the rotation in-process of dust separation arc plate 23, the gravity of counter weight is scraped strip 5 and is crescent so that counter weight is scraped strip 5 and break away from the magnet strip, and then the removal breaks away from the magnet strip to tensile the elastic sheet of stretching.
