It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity. The inside of the injection molding machine barrel cannot filter dust, resulting in a lot of dust inside the injection molding machine barrel, which will lead to lower quality of the processed finished product.

However, there is still stubborn dust on the surface that is difficult to remove by blowing alone. The dust removal effect is poor, which can easily lead to defects in the injection molded products and affect the quality of the products. The raw materials inside the injection molding machine barrel are stationary, and there are problems such as uneven mixing of the raw materials and dust easily settles at the bottom.

[0024] Embodiment: As Figures 1-5 shown, a dust-proof device for the barrel of an injection molding machine according to the present utility model includes a barrel 1. A blower 2 is fixedly installed on the outer side of the barrel 1. The lower end of the blower 2 is communicated with the outer side of the barrel 1 through an air delivery pipe 3. A heater 4 is fixedly connected to the outer periphery of the air delivery pipe 3. The top of the barrel 1 is fixedly connected with a top cover 5. A drive motor 6 is bolted to the center of the surface of the top cover 5. The output end of the drive motor 6 passes through the top cover 5 and is drivingly connected with a rotating shaft 7. A plurality of stirring blades 8 are fixedly connected to the outer periphery of the rotating shaft 7. An extension rod 9 is fixedly welded to the outer periphery of the upper end of the rotating shaft 7. One end of the extension rod 9 is fixedly connected with a brush 10.
[0025] Among them, a filter screen 11 is detachably connected to the upper end of the inner wall of the barrel 1. An air outlet box 12 is fixedly connected to the upper end of the outer periphery of the barrel 1, and the air outlet box 12 is communicated with the filter screen 11. A drainage pipe 13 is fixedly connected to the lower end of the air outlet box 12. A filter bag is arranged inside the air outlet box 12. By providing the drainage pipe 13, when the gas with heat meets the inner wall of the drainage pipe 13 through the air outlet box 12, condensed water droplets will be generated, and the water droplets will drip and be discharged through the drainage pipe 13.
[0026] Among them, a power motor 14 is arranged on one side close to the drive motor 6. The output end of the power motor 14 passes through the top cover 5 and is drivingly connected with a runner 15. The outer circumference of the runner 15 is drivingly connected with a rotating disk 17 through a belt 16. A plurality of material discharge ports are formed on the surface of the rotating disk 17. By arranging the rotating disk 17, it is convenient to adjust the material discharge ports of different sizes according to actual needs, so as to adjust the size of the feeding amount, and the practicability of the device is improved.
[0027] Among them, ventilation holes 18 are formed at the lower end of the inner wall of the material bucket 1. A scraping plate 19 is fixedly connected to the bottom of the rotating shaft 7, and the edge of the scraping plate 19 is in close contact with the inner wall of the material bucket 1. By arranging the scraping plate 19, the ventilation holes 18 are prevented from being blocked, and the dust removal effect is reduced.
[0028] Among them, a through port 20 is formed on the surface of the top cover 5. A feed pipe 21 is fixedly connected to the upper end of the through port 20. A feed port 22 is fixedly connected to the top of the feed pipe 21. A filter port 23 is formed on one side of the feed pipe 21. By arranging the filter port 23, dust can be effectively filtered during feeding, so as to avoid dust entering the device, and the quality of the processed product is effectively improved.
[0029] Among them, a collection hood 24 is fixedly installed on one side of the feed pipe 21, and an air box 25 is fixedly installed on one side of the feed pipe 21. By arranging the collection hood 24, dust can be collected and treated to prevent pollution of the working environment.
[0030] Among them, a discharge port 26 is fixedly connected to the bottom of the material bucket 1, and a valve 27 is fixedly connected below the discharge port 26. By arranging the valve 27, the discharge speed can be effectively controlled, and the material can be discharged quickly.
[0031] Working principle: When in use, put the raw materials into the feed port 22, start the air box 25, and the dust in the fine particles in the air can be effectively filtered through the filter port 23 during feeding, so as to avoid dust entering the device, and the quality of the processed product is effectively improved. Then, according to the size of the required feeding amount, control the power motor 14 to rotate, drive the runner 15 to rotate, drive the rotating disk 17 to rotate through the belt 16, so that the material discharge ports of different sizes are connected with the through port 20 to adjust the feeding amount. Then the raw materials enter the material bucket 1 from the material discharge port. At the same time, control the drive motor 6 to operate, drive the rotating shaft 7 to rotate, and make the stirring blades 8 rotate. The dust attached to the surface of the raw material particles is stirred by the stirring blades 8. By operating the blower 2, the impurities and dust mixed in the hot air are filtered into the air outlet box 12, so that the dust enters the filter bag to achieve the filtering effect. The gas with heat will generate condensed water droplets when it meets the diversion pipe 13, and the water droplets are discharged from the diversion pipe 13. By arranging the brush 10 and the scraping plate 19, the filter net 11 and the ventilation holes 18 are prevented from being blocked, and the dust removal effect is reduced.
