[0002] Flame retardants are functional additives that make flammable polymers flame retardant. They are mainly designed for the flame retardancy of polymer materials. There are many types of flame retardants, which can be divided into additive flame retardants and reactive flame retardants according to their usage.

[0003] During the production process of polymer flame retardants, it is often necessary to quantitatively package the polymer flame retardant particles after granulation. The traditional way is to quantitatively store the polymer flame retardant by manually controlling the feed pump and manually observing the storage conditions in the storage barrel. At the same time, after quantitative storage, the storage barrel needs to be manually sealed. The whole process is relatively cumbersome and wastes manpower, and there will be certain errors in the manual quantitative storage process.

[0038] The placement seat 14 is provided with a clamping mechanism 16 that matches the storage bucket 27. The clamping mechanism 16 is provided by two electric cylinders 161 and two clamping plates 162. The two electric cylinders 161 are respectively fixedly provided on both sides of the placement seat 14, and the output ends of the electric cylinders 161 extend into the placement seat 14 and are fixedly connected to the corresponding clamping plates 162.

[0039] The ports of each storage barrel 27 are provided with a self-sealing tube 17, and one of the self-sealing tubes 17 is plugged with the telescopic tube 10. The lower side of the self-sealing tube 17 is provided with an internal thread, and the port of the storage barrel 27 is provided with an external thread matching the internal thread. The self-sealing tube 17 is connected with the thread of the storage barrel 27, so that when the material in the storage barrel 27 is extracted later, the self-sealing tube 17 is removed so that the port of the storage barrel 27 is exposed, so as to facilitate the material extraction;

[0040] A self-sealing mechanism 18 is provided in the self-sealing tube 17, and a top vibration rod 19 matched with the self-sealing mechanism 18 is provided in the telescopic tube 10. The self-sealing mechanism 18 is composed of a conical material guide seat 181, two spring telescopic rods 182 and a closing ball 183. The conical material guide seat 181 is fixedly provided in the self-sealing tube 17, and the two spring telescopic rods 182 are respectively fixedly provided on both sides of the conical material guide seat 181. The output ends of the two spring telescopic rods 182 are fixedly connected with the closing ball 183, and the closing ball 183 can close the bottom port of the conical material guide seat 181. By cooperating with the spring telescopic rod 182 and the closing ball 183, the pressure change of the closing ball 183 can be utilized to realize the automatic opening and closing of the self-sealing tube 17. The top vibration rod 19 is formed by the mother rod 1 91, a sub-rod 192, an electromagnetic block 193 and a permanent magnet block 194. The mother rod 191 is fixedly arranged in the telescopic tube 10, and the sub-rod 192 is slidably connected to the mother rod 191 through the permanent magnet block 194. The electromagnetic block 193 is embedded in the upper inner wall of the mother rod 191, and a plurality of reset springs 25 are fixedly connected between the electromagnetic block 193 and the permanent magnet block 194. The sub-rod 192 is arranged to abut against the closing ball 183, and the electromagnetic block 193 is electrically connected to the power-off delay relay 24. Through the electromagnetic block 193, the change of the alternating current passed into the electromagnetic block 193 can be utilized to generate a magnetic reciprocating sheet, which, in conjunction with the permanent magnet block 194, can control the sub-rod 192 to reciprocately knock the closing ball 183, so that the closing ball 183 vibrates, which is convenient for material removal.

[0041] The operating principle of the present invention is now described as follows:

[0042] When quantitative packaging is performed, the feed pump 6 will transport the polymer flame retardant stored in the storage box 2 to the quantitative box 4. As the polymer flame retardant is continuously transported, the gravity on the quantitative plate 51 will continue to increase. When the quantitative value is reached, the quantitative plate 51 will drive the conductive block 52 to move downward, so that the conductive block 52 is connected to the conductive sheet 53, so that the normally closed electromagnetic relay 21 is powered on and disconnected, thereby controlling the feed pump 6 to automatically stop, and the normally open electromagnetic relay 22 is automatically closed when powered on, so that the feed pump 8 and the top vibration rod 19 are automatically started. After the feed pump 8 is started, the polymer flame retardant in the quantitative box 4 will be guided to the storage barrel 27 through the telescopic tube 10. After the top vibration rod 19 is connected to the alternating current, the magnetism of the electromagnetic block 193 therein will undergo reciprocating changes, and in conjunction with the permanent magnet block 194, the sub-rod 192 will reciprocately knock the closing ball 183, causing the closing ball 183 to vibrate, so that the polymer flame retardant can fall off better;

[0043] As the polymer flame retardant in the quantitative box 4 is continuously drawn out, the telescopic spring 20 will control the quantitative plate 51 to continuously move upward, so that the material on the quantitative plate 51 can be better sucked by the suction tube 9. At the same time, the conductive block 52 and the conductive sheet 53 will automatically separate. Under the cooperation of the power-on delay relay 23 and the power-off delay relay 24, the power-off delay relay 24 will enable the feed pump 8 to feed for 10 minutes. After the material is transported, the feed pump 8 and the top vibration rod 19 will be automatically powered off and stopped. At the same time, the power-on delay relay 23 will control the feeding pump 6 to automatically start after 10 minutes to continue the feeding work. At this time, the feeding reminder light 26 will light up to remind the staff to carry out the feeding work;

[0044] During the feeding process, the cylinder 11 controls the telescopic tube 10 to contract and separate from the docked storage barrel 27. After separation, due to the lack of squeezing of the top vibration rod 19, the closing ball 183 will automatically close the conical material guide seat 181 under the pull of the spring telescopic rod 182, thereby realizing the automatic closure of the self-sealing tube 17 and avoiding the tedious manual closure. Subsequently, the rotation of the swivel seat 13 is controlled by the transmission cooperation of the stepping motor 151 and the bevel gear assembly 152, so that the next empty storage barrel 27 rotates to the bottom of the telescopic tube 10. Then, the telescopic tube 10 is extended by the cylinder 11 to be plugged into the self-sealing tube 17 on the corresponding storage barrel 27. After plugging, the cylinder 11 is closed, and the top vibration rod 19 in the telescopic tube 10 will squeeze the closing ball 183, so that the closing ball 183 automatically moves away from the conical material guide seat 181, thereby automatically opening the self-sealing tube 17 to wait for subsequent quantitative feeding.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
