[0039] A dust-free production process for masterbatch comprises the following steps:

[0040] Step S1: weighing the masterbatch according to parts by weight, crushing it through the crushing device 310, passing the crushed masterbatch through the first iron chip removal device 100 to absorb iron chips, and then sending it to the batching device 320. At the same time, weighing the colorant and the auxiliary agent according to parts by weight, and mixing and batching them through the batching device 320;

[0041] Step S2: putting the mixed ingredients obtained in step S1 into the extrusion device 330, performing an extrusion operation to form a masterbatch strip, cutting the masterbatch strip into masterbatch by the pelletizing device 340, and then entering the crystallization drying device 350 for drying;

[0042] Step S3: The masterbatch obtained in step S2 is placed in the second iron chip removal device 200. After the second iron chip removal device 200 absorbs the iron chips, the masterbatch is sent to the dust removal device 360 ​​to remove the surface dust of the masterbatch.

[0043] Working principle: The crushing device 310, the batching device 320, the extrusion device 330, the pelletizing device 340, the crystallization drying device 350, and the dust removal device 360 ​​of the present application are all devices used for conventional masterbatches, and the conventional ones in the prior art can be used. After the crushing device 310 crushes the masterbatch, there may be iron filings in the powder, so the iron filings are first removed by the first iron filing removal device 100. The crushed powder is poured into the first hopper 110, and the first driving motor 112 drives the first rotating shaft 113 to rotate, that is, drives the first rotating disk 114 to rotate, so that the first stirring blade 116 stirs the powder to prevent the masterbatch powder from getting stuck and not falling from the first adsorption tube 130 to the second hopper 120. When the masterbatch powder falls, the first electromagnet 131 is energized to adsorb the iron filings in the masterbatch powder. The masterbatch powder processed by the first iron chip removal device 100 is mixed with colorants and additives and enters the batching device 320 for batching, and then is sent to the extrusion device 330 for extrusion molding to obtain masterbatch strips. The pelletizing device 340 pelletizes the masterbatch strips into masterbatches, and then enters the crystallization drying device 350 for drying. The masterbatch is then placed in the second iron chip removal device 200, and the iron chips are adsorbed by the second iron chip removal device 200. That is, the masterbatch is placed on the first screen 230, and the first vibration motor 240 is operated to make the masterbatch continuously vibrate and move to the right, and the first permanent magnet 250 adsorbs the vibrated iron chips in the masterbatch until the masterbatch is completely processed. The masterbatch is placed in the dust removal device 360 ​​for dust removal and then packaged.

[0044] Finally, the first collecting plate 140 is rotated so that the second hopper hole 122 is aligned with the first through hole 141 and the second through hole 142, and then the first electromagnet 131 is controlled to be powered off, so that the iron filings adsorbed on the first adsorption tube 130 fall off and enter the first collecting chamber 146 through the second through hole 142. At the same time, the first cloth roller 261 and the second cloth roller 262 are driven to rotate by the second driving motor 270 and the third driving motor 280, that is, the first cloth 260 is rolled up to the right, and the iron filings on the first cloth 260 enter the second collecting box 290 through the pressure and friction between the first cloth 260 and the first pressing plate 292. Then, the first vacuum pump is started, and negative pressure is formed in the first collecting box, so that the iron filings in the first collecting chamber 146 and the second collecting box 290 are adsorbed into the first collecting box.

[0045] In addition, under normal circumstances, the first discharge pipe 143 is pulled by the first spring 152 to the front end of the first mounting block 150, that is, the second hopper hole 122 is aligned with the first through hole 141, ensuring that the masterbatch powder enters the second hopper 120 from the first hopper 110. When the first discharge pipe 143 is rotated, the first plug post 144 is inserted into the second mounting groove 161, and the first spring sheet 145 is extended to the first limiting groove 162 at both ends by its own elastic force, playing the role of limiting the first plug post 144. In addition, by pressing the first pressing rod 170, the first spring sheet 145 can be pressed against the first plug post 144, so that the first spring sheet 145 can be moved out of the second mounting groove 161. Among them, the first limiting ring 171 and the second limiting ring 172 can limit the movement of the first pressing rod 170 and ensure that the first pressing rod 170 will not fall out of the first guide hole 163.

[0046] Similarly, under normal circumstances, the first cloth roller 261 wraps around excess first cloth 260. When processing iron filings on the first cloth 260, the first cloth 260 is wrapped around the first cloth roller 261. After the processing is completed, the excess first cloth 260 is wrapped around the first cloth roller 261, thereby eliminating the need to replace the first cloth 260 and allowing it to be used repeatedly.

[0047] It is worth mentioning that the technical features of the crushing device 310, the batching device 320, the extrusion device 330, the pelletizing device 340, the crystallization and drying device 350, the dust removal device 360 ​​involved in the patent application of the present invention should be regarded as the prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected according to the conventional selection in the field, and should not be regarded as the inventive point of the patent of the present invention.
