Description

Technical Field

[0001] This application relates to the technical field of thermoplastic elastomer production equipment, and particularly to a foreign object removal device for thermoplastic elastomer production. Background Art

[0002] Thermoplastic elastomer TPE / TPR, also known as artificial rubber or synthetic rubber, has the excellent properties of traditional cross-linked vulcanized rubber such as high elasticity, aging resistance, and oil resistance. At the same time, it has the characteristics of convenient processing and a wide range of processing methods of ordinary plastics. It can be produced by processing methods such as injection molding, extrusion, and blow molding. After the sprue and corner scraps are pulverized, they can be directly reused 100%. After production, the thermoplastic elastomer can be directly used in 3D printing and used in 3D printing in an additive form. When producing thermoplastic elastomers, in order to ensure the quality of the thermoplastic elastomer finished products, it is usually necessary to first use a foreign object removal device to remove foreign impurities in the thermoplastic elastomer raw materials.

[0003] When the traditional foreign object removal device for thermoplastic elastomer production is in use, the raw materials are usually directly put into the removal device. At this time, the raw materials are screened by the sieve plate in the foreign object removal device. At this time, some foreign objects are electrostatically adsorbed on the surface of the raw materials.

By providing an electric telescopic rod, a connecting block, a blanking plate, a conductive plate, a reed, an inclined plate, a discharge case, and a runner group, the runner group can be pushed to move under the action of the electric telescopic rod.

The collection main body 88 includes a collection box 881, a sealing frame 882, an air outlet hole 883, a filter plate 884 and a clamping rod 885. A sealing frame 882 is fixedly connected to one side of the collection box 881. The side of the sealing frame 882 away from the collection box 881 is closely attached to the material guiding plate 86. An air outlet hole 883 is formed in the right side of the collection box 881. The air outlet hole 883 formed in the collection box 881 is connected to the exhaust fan 4. A longitudinally arranged clamping rod 885 is fixedly connected to the bottom of the collection box 881.

The sealing frame 882 is arranged outside the position of the impurity removing hole 87 formed in the material guiding plate 86. Through this setting, after the raw material falls into the bottom case 1, the electric rotating roller 82 drives the connecting rod 83 and the brush 84 to clean the foreign matters attached to the surface of the raw material. Then, the exhaust fan 4 sucks the foreign matters into the collection box 881 through the impurity removing holes 87 formed in the material guiding plate 86 via the return air pipe 14 and the air outlet hole 883. At the same time, the foreign matters are filtered by the filter plate 884. After use, rotate the bolt 11 to make the pushing block 13 leave the oblique groove 886 formed in the clamping rod 885, and then the foreign matters in the collection box 881 can be collected.

[0042] Workflow: When this foreign object removal device for thermoplastic elastomer production is in use, first install this foreign object removal device at a suitable position at the feeding port of the screw conveyor, then connect the power supply and the external controller to the foreign object removal device. Then, the raw materials are quantitatively and segmentally fed into the top shell 2 from the feeding port 5 through the conveyor belt. At this time, start the vibration motor 68 through the external controller. The vibration motor 68 drives the screening plate 622 to vibrate, and the screening plate 622 drives the fixed frame 621 to vibrate, so as to screen the raw materials entering the fixed frame 621, and leave the foreign objects with larger particles in the fixed frame 621. When the screening plate 622 and the fixed frame 621 vibrate, the vibration of the screening plate 622 is transmitted to the rubber sleeve 623. The rubber sleeve 623 deforms through its own elasticity and the deformation grooves 624 provided, preventing the vibration from being transmitted to the electric telescopic rod 61. At the same time, the fixed frame 621 vibrates outside the positioning rod 634, and the rubber ring 635 provided outside the positioning rod 634 deforms under the action of the fixed frame 621. At the same time, the positioning rod 634 drives the fixing plate 633 to vibrate in the rubber frame 631, and the rubber frame 631 further weakens the vibration, preventing the vibration from being transmitted to the support frame 632. After the raw materials on the screening plate 622 are screened, start the electric telescopic rod 61 to extend through the external controller, and at the same time start the conductive plate 643 to be energized. At this time, the static electricity in the raw materials arranged on the surface of the conductive plate 643 is carried away by the current flowing in the conductive plate 643, achieving the effect of removing the static electricity in the raw materials. At the same time, the runner group 67 provided at the bottom of the electric telescopic rod 61 pushes the blanking plate 642 to rotate outside the connecting block 641, thereby driving the conductive plate 643 to rotate slightly, increasing the distance between the two conductive plates 643. At this time, the raw materials move downward through the gap between the two conductive plates 643. The raw materials pass through the inclined plate 65 and enter the bottom shell 1 through the discharge shell 66. Then the raw materials fall on the surface of the guide plate 86 and roll to the lower left corner through the inclined guide plate 86. At this time, start the electric roller 82 and the exhaust fan 4 through the external controller. The electric roller 82 drives the connecting rod 83 and the brush 84 to rotate. When the raw materials pass between the connecting rods 83, the surface of the raw materials is swept by the brush 84. After the static electricity on the surface of the raw materials is removed, the foreign objects are more easily scraped off. At this time, the exhaust fan 4 is started to drive the air flow in the bottom shell 1. At this time, the air drives the scraped impurities to pass through the impurity removal holes 87 provided in the guide plate 86 and enter the collection box 881. At this time, the filter plate 884 in the collection box 881 filters the impurities. Then the air will return to the bottom shell 1 again under the action of the exhaust fan 4 and the return air pipe 14, realizing the removal of foreign objects on the surface of the raw materials. Then the raw materials pass through the blanking shell 3 and enter the screw conveyor mechanism, and are transmitted through the screw conveyor mechanism. After long-term use, this foreign object removal device needs to be cleaned. At this time, turn off this foreign object removal device through the controller, and then open the box door 7. At this time, pull up the baffle 626 upward, and the baffle 626 drives the insertion rod 627 to move in the rubber block 628 until the insertion rod 627 is taken out of the rubber block 628,Then, the foreign object can be taken out from the notch of the fixed frame 621, and the screening plate 622 can be cleaned. After that, the baffle 626 is reinstalled, and finally the box door 7 is closed. When cleaning the collection box 881, first rotate the bolt 11. The bolt 11 drives the push block 13 to move within the chute 12 opened in the fixed block 10 until the push block 13 leaves the bottom of the clamping rod 885. Then, the collection box 881 is driven downward by the clamping rod 885 until the collection box 881 is taken out from the bottom shell 1. After that, the foreign object in the collection box 881 is recycled, and then the collection box 881 is put back into the bottom shell 1. At this time, the clamping rod 885 is aligned with the groove on one side of the fixed block 10. When the collection box 881 enters the bottom shell 1, the clamping rod 885 enters the groove on one side of the fixed block 10. Then, rotate the bolt 11. The bolt 11 drives the push block 13 to move. The push block 13 enters the inclined groove 886 opened in the clamping rod 885. At this time, the push block 13 pushes the clamping rod 885 upward through the inclined plane and the inclined groove 886 opened in the clamping rod 885. The clamping rod 885 pushes the collection box 881 upward, so that the sealing frame 882 provided at the top of the collection box 881 is closely attached to the material guiding plate 86. After that, the raw material is fed into the stirring device, and the raw material is mixed evenly by the stirring device. Then, it is fed into the extruder, melted by heating in the extruder and then extruded. After extrusion, it is made into thermoplastic elastomer particles through cooling and cutting. Then, the particles are directly fed into the 3D printer. The thermoplastic elastomer particles as the additive are melted by the 3D printer and then sprayed out through the nozzle, and the thermoplastic elastomer particles are printed into the required shape.,
