An intelligent centralized feeding system

Abstract

The present invention relates to the technical field of injection molding feeding, and discloses an intelligent centralized feeding system, which includes a storage barrel, a drying barrel and a dehumidifying dryer. The air inlet end and the air outlet end of the drying barrel are respectively connected to the air outlet end and the air inlet end of the dehumidifying dryer through pipelines. The discharging end of the storage barrel is connected with a separation and preheating assembly, and the discharging end of the separation and preheating assembly is connected to the drying barrel; A separation and preheating assembly is arranged during the conveying process of the storage barrel and the drying barrel. The separation and preheating assembly uses a vortex tube for material conveying. When conveying materials, a vortex air flow can be generated, which drives the materials to generate a vortex, causing the materials to undergo centrifugal separation, so that the powder particles in the materials can be separated during the conveying process. At the same time, the vortex tube will generate hot air flow. While using the hot air flow to drive the material conveying, the materials are preheated, so that the temperature of the materials entering the drying barrel rises, thereby improving the drying efficiency of the materials.

[0055] In this embodiment, specifically, the vortex tube 210 includes:

[0056] Vortex tube body 211;

[0057] Nozzle 212, arranged inside the vortex tube body 211;

[0058] Cold end spray pipe 213, arranged at one end of the vortex tube body 211;

[0059] Hot end spray pipe 214, arranged at the other end of the vortex tube body 211.

[0060] In this embodiment, when the compressed gas enters the vortex tube body 211, a vortex air flow is generated through the nozzle 212. The vortex air flow generates a cold air flow at the cold-end ejection tube 213 and a hot air flow at the hot-end ejection tube 214.

[0061] In this embodiment, specifically, the feeder 220 includes:

[0062] A feed pipe body 221;

[0063] A feed interface 222, which is arranged at the feed end of the feed pipe body 221.

[0064] In this embodiment, the material in the storage barrel 100 is conveyed to the feed interface 222 by a pipeline under negative pressure, and then enters the feed pipe body 221 through the feed interface 222.

[0065] In this embodiment, specifically, the feed interface 222 is quickly connected to the discharge pipeline of the storage barrel 100 by means of plugging.

[0066] In this embodiment, the pipeline of the storage barrel 100 is quickly connected to and disassembled from the feed interface 222 by means of plugging.

[0067] In this embodiment, specifically, the separator 240 includes:

[0068] A separation pipe body 241;

[0071] In this embodiment, when the material in the centrifuge tube 230 enters the separation pipe body 241, the powder particles in the center are discharged from the separation pipe body 241 under the action of the partition pipe 243, and the larger powders on the outside are blocked by the partition pipe 243 on the outside. Finally, they are conveyed to the drying cylinder 400 through the discharge interface 242 and the pipeline.

[0072] In this embodiment, specifically, the discharge interface 242 is connected to the feed pipeline of the drying cylinder 400 by means of plugging.

[0078] In this embodiment, specifically, the cold end outlet of the vortex tube 210 is connected to the cooling air source end of the dehumidifying and drying machine 500.

[0079] In this embodiment, the cold air generated by the vortex tube 210 can directly cool the honeycomb runner in the dehumidifying and drying machine 500, so that the dehumidifying and drying machine 500 does not need to externally connect an additional cold source, which can improve the use efficiency of the vortex tube 210 and achieve the purpose of energy saving.

[0080] In this embodiment, specifically, the discharging end of the drying cylinder 400 is connected to a material selection station 600.

[0081] In this embodiment, the material selection station 600 distributes the materials to the injection molding equipment.

[0082] Refer to Figures 1-4 , the materials in the storage cylinder 100 are connected to the feeding interface 222 by a pipeline. When feeding, the air compressor 300 is started, so that the air compressor 300 conveys the compressed gas into the vortex tube body 211. When the compressed gas enters the vortex tube body 211, a vortex air flow is generated through the nozzle 212. The vortex air flow generates a cold air flow at the cold end ejection pipe 213 and a hot air flow at the hot end ejection pipe 214. When the vortex hot air flow passes through the feeding pipe body 221, a negative pressure is generated at the feeding interface 222, so that the materials enter the feeding pipe body 221 through the connected pipeline. When the materials and the air flow pass through the centrifugal tube 230, a centrifugal stratification phenomenon occurs, so that the large-particle materials are conveyed on the outer layer and the powder particles are conveyed on the inner layer. When the air flow passes through the separator 240,. By setting a separation and preheating assembly, the separation and preheating assembly is composed of a vortex tube, a feeder, a centrifugal tube, a separator and a filter. The vortex tube is externally connected to an air compressor and can generate a vortex air flow. When feeding, the powder particles in the center are discharged from the separation tube body 241 under the action of the partition tube 243 and are filtered and discharged through the filter 250. The larger powder on the outside is blocked on the outside by the partition tube 243. Finally, it is conveyed to the inside of the drying cylinder 400 through the discharge interface 242 and the pipeline to complete the conveying of the materials. Finally, the materials are dehumidified and dried under the action of the drying cylinder 400 and the dehumidifying and drying machine 500. After drying, the material selection station 600 distributes the materials to the injection molding equipment.

[0083] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
