DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a molding device for inorganic halogen-free flame retardant masterbatch, comprising a fixed frame 1 and a conveying net 22, a support plate 3 is fixedly connected to the top left side of the fixed frame 1, a hollow column 4 is fixedly connected to the top of the support plate 3, a feed frame 5 is connected to the top left side of the hollow column 4, a servo motor 6 is fixedly connected to the left side of the feed frame 5, an output end of the servo motor 6 passes through the feed frame 5 and is fixedly connected to a driving bevel gear 7, a guide frame 8 is fixedly connected to the inner left side of the feed frame 5, a rotating rod 9 is fixedly connected to the inner top of the guide frame 8, a driven bevel gear 10 is fixedly connected to the middle and upper part of the outer side of the rotating rod 9, and the driven bevel gear 10 is fixedly connected to the driven bevel gear 10. 0 is meshed and connected with the active bevel gear 7, a plurality of stirring rods 11 are fixedly connected to the outer side of the rotating rod 9 at equal intervals, a fixed plate 12 is fixedly connected to the top of the hollow column 4, an electric telescopic rod 13 is fixedly connected to the left side of the fixed plate 12, the output end of the electric telescopic rod 13 passes through the feed frame 5 and is fixedly connected to a baffle 14, a circulation mechanism 2 is arranged inside the fixed frame 1, the size of the baffle 14 matches the size of the middle and lower part of the inner side of the feed frame 5, a servo motor 15 is fixedly connected to the left end of the hollow column 4, the output end of the servo motor 15 passes through the hollow column 4 and is fixedly connected to an extrusion screw 16, and the right end of the hollow column 4 passes through the fixed frame 1;

[0031] Specifically, the servo motor 6 can drive the active bevel gear 7 to rotate, and the driven bevel gear 10 will rotate accordingly, and the stirring rod 11 will also rotate accordingly. This design allows the material entering the feed frame 5 to be fully mixed under the action of the stirring rod 11, and then the electric telescopic rod 13 can drive the baffle 14 to move to the right. This action cleverly changes the flow direction of the material, so that the mixed material can smoothly fall into the hollow column 4. This design not only helps to fully mix and disperse the flame retardant masterbatch material, but also ensures that the flame retardant performance of the molded product is uniform.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The circulation mechanism 2 includes a filter screen 201, which is fixedly connected to the inside of the fixed frame 1. A water pump 202 is fixedly connected to the right side of the rear end of the fixed frame 1. The output end of the water pump 202 passes through the fixed frame 1. The input end of the water pump 202 is connected to a connecting pipe 203. A hollow tube 204 is fixedly connected to the top of the inner side of the fixed frame 1. The top of the connecting pipe 203 is connected to the rear side of the hollow tube 204. The bottom of the hollow tube 204 is equidistantly connected to a plurality of nozzles 205. A refrigeration unit 206 is fixedly connected to the right side of the front end of the fixed frame 1. The output end of the refrigeration unit 206 passes through the fixed frame 1.

[0033] Specifically, cooling water is pumped out by water pump 202 and sprayed evenly on the extruded flame retardant masterbatch through nozzle 205 to achieve rapid and uniform cooling. However, the water used in the cooling process will absorb the heat of the flame retardant masterbatch and heat up. In order to ensure the continuous cooling effect of the water source, the impurities in the water can be filtered out by filter 201 to ensure the cleanliness of the water source. The filtered water will return to the fixed frame 1 again to prepare for recycling. Next, the water source flowing back to the fixed frame 1 can be cooled by refrigeration unit 206. Finally, the water source after cooling treatment will be recycled again by water pump 202. This recycling method not only improves the utilization efficiency of water resources, but also reduces production costs and environmental pollution. At the same time, since the entire cooling system can be automatically controlled, the production efficiency and practicality of the device are greatly improved.

[0034] Reference Figure 1 A stepper motor 17 is fixedly connected to the upper middle part of the left side of the fixed frame 1, the output end of the stepper motor 17 passes through the fixed frame 1, and blades 18 are fixedly connected to the outer sides of the output end of the stepper motor 17 at equal intervals;

[0035] Specifically, the stepper motor 17 can drive the blade 18 to rotate to cut the extruded masterbatch.

[0037] Specifically, the stepper motor 19 can drive the first rotating shaft 20 to rotate, and the second rotating shaft 21 will rotate accordingly, thereby driving the conveying network 22 to rotate to transport the materials.

[0038] Reference Figure 1 A controller 23 is fixedly connected to the middle of the right front end of the fixed frame 1. The controller 23 is electrically connected to the water pump 202, the refrigeration unit 206, the servo motor 6, the electric telescopic rod 13, the servo motor 15, the stepper motor 17 and the stepper motor 19 respectively. A protective cover 24 is provided on the outside of the controller 23. One end of the protective cover 24 is rotatably connected to the front side of the fixed frame 1.

[0039] Specifically, the operation of the water pump 202, the refrigeration unit 206, the servo motor 6, the electric telescopic rod 13, the servo motor 15, the stepper motor 17 and the stepper motor 19 can be controlled by the controller 23, and the protective cover 24 can protect the controller 23 from being damaged by external factors.

[0040] Working principle: When using the device, first pour the flame retardant masterbatch material to be processed into the feed frame 5, and at the same time start the servo motor 6 to drive the active bevel gear 7 to rotate. The driven bevel gear 10 will rotate accordingly due to the meshing with the active bevel gear 7, thereby driving the stirring rod 11 to rotate. At this time, the material entering the feed frame 5 can be fully mixed, and then the baffle 14 can be driven to move to the right by the electric telescopic rod 13. At this time, the mixed material will fall into the hollow column 4, and then the extrusion screw 16 can be driven to rotate by the servo motor 15, so that the material can be extruded and formed. After the formed material comes out, start the stepper motor 17 to drive the blade 18 to rotate and cut the formed material into cutting work, so that the flame retardant masterbatch material can be fully mixed and dispersed, thereby ensuring the flame retardancy of the formed product. The performance is uniform, and thus can meet the needs of users. The cut masterbatch will fall onto the conveying net 22, and then starting the stepper motor 19 can drive the first rotating shaft 20 to rotate, and the second rotating shaft 21 will rotate accordingly, so that the conveying net 22 can start running, which can facilitate the subsequent material transportation work, and first inject cooling water into the right side of the fixed frame 1, and then the cooling water can be pumped out through the water pump 202 and then the extruded flame retardant masterbatch is cooled through the nozzle 205. The water source after the flame retardant masterbatch is cooled will first pass through the filter 201 to filter the impurities therein, and the water source will return to the fixed frame 1 again. At this time, starting the refrigeration unit 206 can cool the water source flowing back into the fixed frame 1, and then the water source can be recycled through the water pump 202, thereby improving the practicality of the device.
