[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Example

[0028] like Figure 1 、 2 As shown, it includes a raw material conveying component 10 and a loading component 20 at the output end of the raw material conveying component 10; the loading component 20 includes a loading box 21 located at the top of the injection port of the injection molding machine and a blanking plate 22 on the inner wall of the side of the loading box 21.

[0029] It should be noted that, in this embodiment, the raw material conveying component 10 conveys the raw material into the loading box 21 of the loading component 20. The raw material enters through the feed port 211 at the top of the loading box 21 and is finally output from the discharge port 212 and injected into the injection port of the injection molding machine.

[0030] During this period, the raw materials first fall to the top of the blanking plate 22 and accumulate over time. At this time, the blanking plate 22 is in a horizontal state.

[0031] like Figure 3 、 5 As shown, the interception component 23 is located on the inner wall of one end of the feeding box 21 and at the bottom of the blanking plate 22; the feeding port 211 is at the top of the feeding box 21, and the discharging port 212 is at the bottom of the feeding box 21;

[0032] The discharge port 212 is located at the top of the injection port of the injection molding machine; the interception component 23 includes at least one telescopic rod 231 on the inner wall of one end of the loading box 21, and a gear rod 232 at the execution end of the telescopic rod 231; the side wall of the gear rod 232 is arranged perpendicular to the telescopic rod 231, and multiple magnetic plates 223 are linearly distributed at the bottom of the blanking plate 22, and the magnetic plates 223 are arranged corresponding to the counterweight magnetic block 224.

[0033] It should be noted that, in this embodiment, the plurality of magnetic plates 223 at one end of the bottom of the blanking plate 22 are provided correspondingly to the counterweight magnetic blocks 224. In fact, before feeding, the number of the counterweight magnetic blocks 224 can be adjusted according to the processing time or cooling gap time of the injection molding machine, thereby controlling the feeding speed and effectively preventing the raw material from overflowing.

[0034] When the loading needs to be stopped in time due to equipment failure or other reasons, the telescopic rod 231 in the interception component 23 works, and its execution end drives the gear rod 232 to move forward. The gear rod 232 will gradually approach the bottom of the other end of the blanking plate 22 to limit it and prevent the raw materials from entering the bottom of the blanking plate 22. The execution time of the telescopic rod 231 is short, and it can be used for timely operation in emergencies.

[0035] like Figure 2 、 3 As shown in Figure 6, the side wall of the blanking plate 22 is connected to the shaft 221 that is inserted into the side wall of the loading box 21, the inclined guide plate 222 is at the top end of the blanking plate 22, multiple magnetic plates 223 are at the bottom end of the blanking plate 22, and the counterweight magnet 224 is at the bottom of the magnetic plate 223; one end of the inclined guide plate 222 is slidingly connected to the inner wall of one end of the loading box 21, the arc-shaped surface at one end of the inclined guide plate 222 is a circular surface with the rotation axis of the shaft 221, and the block 233 is at the top of the other end of the blanking plate 22 and the inner wall of the other end of the loading box 21.

[0036] It should be noted that, in this embodiment, a counterweight magnetic block 224 is provided at the bottom of one end of the blanking plate 22, and the other end thereof is limited by a block 233 on the inner wall of the other end of the loading box 21. The blanking plate 22 cannot rotate beyond the position of the block 233; the inclined guide plate 222 is used to prevent the accumulation of raw materials on its top.

[0037] As the raw materials continue to accumulate, the weight of the raw materials exceeds the total weight of all the counterweight magnetic blocks 224 , the blanking plate 22 rotates, and the raw materials accumulated on the top of the blanking plate 22 fall to the bottom of the blanking plate 22 and flow out from the discharge port 212 .

[0038] The working principle of this utility model is:

[0039] The raw material conveying component 10 conveys the raw material into the loading box 21 in the loading component 20. The raw material enters from the feed port 211 at the top of the loading box 21 and is finally output from the discharge port 212 and injected into the injection port of the injection molding machine.

[0040] During this period, the raw materials first fall to the top of the blanking plate 22 and accumulate over time. At this time, the blanking plate 22 is in a horizontal state. Since a counterweight magnetic block 224 is provided at the bottom of one end of the blanking plate 22, the other end of the blanking plate 22 is limited by a block 233 on the inner wall of the other end of the loading box 21. The blanking plate 22 cannot rotate beyond the position of the block 233. The inclined guide plate 222 is used to prevent the raw materials from accumulating on the top of it.

[0041] As the raw materials continue to accumulate, the weight of the raw materials exceeds the total weight of all the counterweight magnetic blocks 224, the blanking plate 22 rotates, and the raw materials accumulated on the top of the blanking plate 22 fall to the bottom of the blanking plate 22 and flow out from the discharge port 212;

[0042] It should be further explained that the plurality of magnetic plates 223 at one end of the bottom of the blanking plate 22 are arranged correspondingly to the counterweight magnetic blocks 224. Before the material is actually loaded, the number of the counterweight magnetic blocks 224 can be adjusted according to the processing time or cooling gap time of the injection molding machine, thereby controlling the loading speed and effectively preventing the raw material from overflowing.

[0043] When the loading needs to be stopped in time due to equipment failure or other reasons, the telescopic rod 231 in the interception component 23 works, and its execution end drives the gear rod 232 to move forward. The gear rod 232 will gradually approach the bottom of the other end of the blanking plate 22 to limit it and prevent the raw materials from entering the bottom of the blanking plate 22. The execution time of the telescopic rod 231 is short, and it can be used for timely operation in emergencies.

[0044] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
