[0028] Referring to the attached Figure 1 and Figure 2 As shown, the embodiment of this application provides a halogen-free flame retardant masterbatch granulation feeding device, which includes a feeding hopper 1 and a feeding hopper 2. The feeding hopper 2 is integrally formed at the bottom of the feeding hopper 1. The feeding hopper 2 is funnel-shaped for easy feeding. An inlet is provided at the bottom of the feeding hopper 2, and the inlet is connected to a mixer. Among them, the feeding hopper 1 is used to cache the halogen-free flame retardant masterbatch raw materials, and the feeding hopper 2 is used to feed the halogen-free flame retardant masterbatch raw materials into the mixer. A first pushing mechanism 7 and a second pushing mechanism 12 that cooperate with each other are arranged in the feeding hopper 1. Through the cooperation of the first pushing mechanism 7 and the second pushing mechanism 12, the halogen-free flame retardant masterbatch raw materials are pushed into the feeding hopper 2 in multiple times, with a certain amount each time, so as to avoid the problem of feeding blockage caused by all the halogen-free flame retardant masterbatch raw materials pouring into the feeding hopper 2 at one time.

[0029] Specifically:

[0030] See Figure 1 and Figure 2As shown in the figure, a partition 3 integrated with the inner wall is arranged inside the charging hopper 1. The partition 3 divides the inside of the charging hopper 1 to form a charging bin 4. The bottom of the charging bin 4 is closed with the feeding hopper 2. A hopper cover 5 is arranged at the top of the charging hopper 1. The hopper cover 5 is fixed by means of threaded connection. A feeding port 6 is arranged on the hopper cover 5. Through the feeding port 6, the halogen-free flame retardant masterbatch raw material can be put into the charging bin 4. See Figure 2 As shown in the figure, along the long axis direction of the charging bin 4, a first pushing mechanism 7 for pushing the halogen-free flame retardant masterbatch raw material in the bin to the other side is arranged on one side of the charging bin 4. The first pushing mechanism 7 includes an automatic telescopic member 701 and a first pushing plate 702. Among them, the automatic telescopic member 701 is fixed to the outer side wall of the charging bin 4 by screws, and the automatic telescopic member 701 extends from outside the charging bin 4 into the charging bin 4. The first pushing plate 702 is arranged inside the charging bin 4 and is fixedly connected with the automatic telescopic member 701. Thus, it can be imagined that under the elongation action of the automatic telescopic member 701, the first pushing plate 702 is pushed to push the halogen-free flame retardant masterbatch raw material to the opposite side. After all the halogen-free flame retardant masterbatch raw material is pushed to the opposite side, the automatic telescopic member 701 contracts and resets. Here, the automatic telescopic member 701 can be an electric push rod 1225, a hydraulic cylinder or a cylinder, etc.

[0031] Furthermore, a first bin opening and a second bin opening are arranged on one side of the charging bin 4 relative to the first pushing mechanism 7. The first bin opening and the second bin opening are arranged in the same straight line, and the connection line between the first bin opening and the second bin opening is perpendicular to the pushing direction of the first feeding mechanism. An openable movable bin door 11 is arranged at the first bin opening. A first bin chamber 8 is arranged outside the first bin opening. The first bin chamber 8 is provided with a feeding port 10 communicating with the feeding hopper 2. A second bin chamber 9 is arranged outside the second bin opening. The second bin chamber 9 is provided with a second pushing mechanism 12 for periodically pushing the halogen-free flame retardant masterbatch raw material into the first bin chamber 8. During the feeding process, the automatic telescopic member 701 pushes the halogen-free flame retardant masterbatch raw material to the opposite side. Under the action of the second pushing mechanism 12, the halogen-free flame retardant masterbatch raw material is pushed to the first bin chamber 8 side in batches. The movable bin door 11 moves towards the inside of the first bin chamber 8 under the action of the thrust, so that the halogen-free flame retardant masterbatch raw material can enter the first bin chamber 8, enter the feeding hopper 2 from the feeding port 10, and be fed by the feeding hopper 2.

[0032] In the above, see Figure 2 and Figure 3As shown in the figure, the second feeding mechanism 12 includes a second pushing plate 121 and a reciprocating driving mechanism 122 for realizing the reciprocating movement of the second pushing plate 121. The second pushing plate 121 is arranged in the second chamber 9. In the natural state, the front end of the second pushing plate 121 is located at the second bin opening. The length of the second pushing plate 121 is the same as the short-axis length of the feeding hopper 1. Thus, when the second pushing plate 121 moves towards the first bin opening to push the material, the second pushing plate 121 always keeps blocking the remaining non-halogenated flame retardant masterbatch raw materials in the feeding bin 4, preventing the non-halogenated flame retardant masterbatch raw materials from entering the second chamber 9. The reciprocating driving mechanism 122 includes a driving motor 1221, a crank and connecting rod mechanism, a strip-shaped frame 1224, and a push rod 1225. The crank and connecting rod mechanism includes a crank and connecting rod 1222 and a pin shaft 1223. The output end of the driving motor 1221 is connected to one end of the crank and connecting rod 1222, and the pin shaft 1223 is fixed to the other end of the crank and connecting rod 1222. The push rod 1225 is arranged in the second chamber 9. One end of the push rod 1225 is fixed to the second pushing plate 121, and the other end is fixedly connected to the middle of the strip-shaped frame 1224. The pin shaft 1223 is inserted into the strip-shaped frame 1224. As the driving motor 1221 rotates, the pin shaft 1223 slides in the strip-shaped frame 1224. Based on the reciprocating driving mechanism 122, when the driving motor 1221 rotates, the crank and connecting rod 1222 drives the pin shaft 1223 to slide in the strip-shaped frame 1224, thereby applying periodic thrust and pulling force to the strip-shaped frame 1224, driving the push rod 1225 to push forward and pull back periodically, and driving the second pushing plate to push the non-halogenated flame retardant masterbatch raw materials into the first chamber 8 batch by batch, completing batch feeding, and thus preventing the feeding port from being blocked.

[0033] In this embodiment, the movable bin door 11 includes a door panel 1101 and a spring 1102. The door panel 1101 is located at the first bin opening in the natural state. The spring 1102 is arranged in the first chamber 8 and is fixedly connected to the door panel 1101 and the inner wall surface of the first chamber 8 respectively. It can be imagined that when the second pusher pushes the non-halogenated flame retardant masterbatch raw materials towards the first chamber 8, the door panel 1101 moves into the first chamber 8 under the thrust, so that the non-halogenated flame retardant masterbatch raw materials enter the first chamber 8 and fall into the feeding hopper 2 through the feeding port 10. After one push of the material, the second pushing plate 121 moves towards the second chamber 9 under the action of the reciprocating driving mechanism 122. The door panel 1101 loses the thrust and resets under the action of the spring 1102. Under the next push of the material by the reciprocating driving mechanism 122, the door panel 1101 opens again. Repeating this process, intermittent feeding is completed batch by batch, thus avoiding the situation that the non-halogenated flame retardant masterbatch raw materials flood into the feeder at one time and causing the feeding to be blocked.

[0034] In an exemplary embodiment, refer to Figure 2As shown, ventilation holes 15 are provided on the partition plate 3. The aperture of the ventilation holes 15 is smaller than the particle size of the raw material of the halogen-free flame retardant masterbatch. A drying chamber 13 is formed between the outer side of the partition plate 3 and the feed hopper 1. A heating fan 14 is arranged in the drying chamber 13. The hot air generated by the heating fan 14 passes through the ventilation holes 15 to dry the raw material of the halogen-free flame retardant masterbatch in the feed bin 4. Without limitation, the model of the heating fan 14 can be YH-DR-1220-ZF-801.

[0035] In summary, a feeding device for halogen-free flame retardant masterbatch granulation provided by an embodiment of the present application, by setting a feed hopper 1 and a feeding hopper 2, a feed bin 4 is arranged in the feed hopper 1, and the raw material of the halogen-free flame retardant masterbatch is pushed towards the first chamber 8 and the second chamber 9 in the feed bin 4 by a first pushing mechanism 7. The second pushing mechanism 12 periodically pushes the raw material of the halogen-free flame retardant masterbatch into the first chamber 8 in batches, and enters the feeding hopper 2 through the feeding port 10 to complete the feeding, thereby preventing the raw material of the halogen-free flame retardant masterbatch from all pouring into the feeding hopper 2 at one time, effectively solving the problem of feeding blockage.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
