[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] It is understandable that, referring to Figures 1 to 3 The feeding device of the injection molding machine of the present invention includes a barrel 100, an iron removal mechanism 200 and a heating mechanism 300. The barrel 100 is provided with a feed pipe 110 and a discharge pipe 120. The feed pipe 110 and the discharge pipe 120 are both connected to the barrel 100. The feed pipe 110 is used to input materials into the barrel 100, and the discharge pipe 120 is connected to the injection molding machine; the iron removal mechanism 200 includes an iron removal box 210 and a plurality of magnets 220. The iron removal box 210 is arranged between the barrel 100 and the feed pipe 110. The inner wall of the iron removal box 210 is connected to two guide plates 211. The two guide plates 211 are connected to the inner wall of the iron removal box 210. The guide plates 211 are arranged at intervals along the vertical direction, one end of the two guide plates 211 is fixedly connected to the opposite sides of the iron removal box 210, and a gap 212 is provided between the other end of the two guide plates 211 and the inner wall of the iron removal box 210. The two guide plates 211 are arranged at an angle, the magnets 220 are fixedly connected to the guide plates 211, and the multiple magnets 220 are arranged at intervals; the heating mechanism 300 includes a hot air component 310 and an exhaust pipe 320, the hot air component 310 is used to output hot air to the barrel 100, and the exhaust pipe 320 is connected to the barrel 100.

[0029] The feed pipe 110 is connected to the upper end of the barrel 100, the discharge pipe 120 is connected to the lower end of the barrel 100 and is communicated with the injection molding machine, the iron removal box 210 is arranged between the barrel 100 and the feed pipe 110, and two guide plates 211 are arranged in the iron removal box 210 along the vertical direction. One end of the two guide plates 211 is fixedly connected to the inner wall of the iron removal box 210, and a gap 212 is set between the other end and the inner wall of the iron removal box 210. A plurality of magnets 220 are arranged at intervals on the guide plates 211. The material is fed into the feed pipe 110. The material is put into the iron removal box 210 so that the material slides on the guide plate 211, then falls from the gap 212 to another guide plate 211, and then falls into the barrel 100. A plurality of magnets 220 are arranged at intervals on the guide plates 211. The iron filings in the material can be adsorbed by the plurality of magnets 220, and the material can slide on the two guide plates 211 in turn, which can extend the contact time between the material and the magnets 220, thereby improving the separation efficiency of the material and the iron filings, reducing the possibility of iron filings entering the injection molding machine, and improving the processing quality.

[0030] The hot air component 310 can input hot air into the barrel 100, and the exhaust pipe 320 is connected to the barrel 100 to maintain air pressure balance inside and outside the barrel 100, so that the hot air can smoothly enter the barrel 100, which can facilitate drying of the material, improve the dryness of the material, and improve the processing quality.

[0031] It should be noted that the two guide plates 211 are arranged vertically in the iron removal box 210, and the two guide plates 211 are arranged tilted from top to bottom so that the material can slide on the two guide plates 211 in turn, slowing down the movement speed of the material, extending the contact time between the material and the magnet 220, and improving the separation efficiency of the material and iron chips.

[0032] In addition, after the material is input into the barrel 100 through the feed pipe 110, the hot air component 310 can input hot air into the barrel 100, thereby heating the material and accelerating the evaporation of moisture in the material, so that the material output by the discharge pipe 120 can remain dry, reducing the possibility of moisture entering the injection molding machine and improving processing quality.

[0033] It is understandable that, referring to Figure 3 and Figure 5The guide plate 211 is provided with a plurality of mounting slots 213. The mounting slots 213 are arranged along the length of the guide plate 211 and are spaced apart. The magnets 220 are fixedly connected to the mounting slots 213, and the depth of the mounting slots 213 is less than the height of the magnets 220. The mounting slots 213 are arranged along the length of the guide plate 211 and are spaced apart on the guide plate 211. The magnets 220 are arranged in the mounting slots 213 so that the magnets 220 can be stably fixed on the guide plate 211. By setting the depth of the mounting slots 213 to be less than the height of the magnets 220, the magnets 220 can protrude from the guide plate 211, thereby increasing the contact area between the magnets 220 and the material, facilitating the magnets 220 to separate iron filings from the material, and improving the efficiency of removing iron filings.

[0034] It should be noted that the magnet 220 can be fixed in the mounting groove 213 by means of fasteners, adhesive, etc., so that the magnet 220 can be stably mounted on the guide plate 211 .

[0035] Specifically, refer to Figure 5 The iron removal mechanism 200 further includes a scraper 230, which is provided with a chute 231. The guide plate 211 and the magnet 220 are both slidably connected to the chute 231. The shapes of the guide plate 211 and the magnet 220 match the shape of the chute 231. The scraper 230 is provided with a chute 231. The guide plate 211 and the magnet 220 are both inserted into the chute 231. By setting the shapes of the guide plate 211 and the magnet 220 to match the shape of the chute 231, the guide plate 211 and the magnet 220 can abut against the side wall of the chute 231, so that the scraper 230 can scrape off the iron filings adsorbed on the magnet 220, thereby facilitating the cleaning of the iron filings and improving the ease of use of the iron removal mechanism 200.

[0036] It should be noted that the outer contour formed by the guide plate 211 and the magnet 220 matches the shape of the chute 231, so that the side wall of the chute 231 can smoothly scrape off the iron filings adsorbed on the magnet 220, and prevent the iron filings from accumulating on the guide plate 211, thereby improving the cleaning efficiency of the iron filings.

[0037] In addition, the scraper 230 may also be arranged separately from the guide plate 211 to prevent the scraper 230 from blocking the input of materials, which is not limited here.

[0038] It is understandable that, referring to Figure 2 and Figure 3The inner wall of the iron removal box 210 is provided with a protruding support block 214, which is located in the gap 212, and the guide plate 211 can abut against the support block 214. The support block 214 is fixedly connected to the inner wall of the iron removal box 210. By arranging the support block 214 to abut against the guide plate 211, the support block 214 can support the guide plate 211, so that the guide plate 211 can be subjected to force balance, which can improve the bearing capacity of the guide plate 211, facilitate the guide plate 211 to bear the weight of the material, reduce the possibility of the guide plate 211 breaking, and improve the reliability of the iron removal mechanism 200.

[0039] It should be noted that the width of the support block 214 is smaller than the width of the guide plate 211, so that when the material slides out from the guide plate 211, the material can fall into the gap 212 from both sides of the support block 214, avoiding the support block 214 blocking the input of the material.

[0040] It is understandable that, referring to Figure 1 、 Figure 2 and Figure 4 The hot air assembly 310 includes a connecting pipe 311, a heating element 312 and a fan 313. One end of the connecting pipe 311 is connected to the barrel 100, and the other end of the connecting pipe 311 is connected to the fan 313. The heating element 312 is located in the connecting pipe 311 and is used to heat the air. The fan 313 is used to drive the airflow into the connecting pipe 311. One end of the connecting pipe 311 is connected to the barrel 100, and the other end is connected to the fan 313. The fan 313 can drive the airflow from the connecting pipe 311 to the barrel 100. The heating element 312 is located in the connecting pipe 311. By setting the heating element 312, the airflow can be heated, so that the hot air can be blown into the barrel 100, so that the hot air can heat the material, thereby accelerating the evaporation of moisture in the material, keeping the material dry, and improving the processing quality.

[0041] Specifically, refer to Figure 2 and Figure 4 A baffle 314 is provided in the connecting tube 311. The baffle 314 is located between the barrel 100 and the heating element 312. The baffle 314 is provided with a plurality of ventilation holes 315 at intervals. The baffle 314 is provided in the connecting tube 311. By providing the baffle 314, the material in the barrel 100 can be prevented from entering the connecting tube 311. The baffle 314 is provided with a plurality of ventilation holes 315 so that hot air can smoothly pass through the ventilation opening into the barrel 100, thereby preventing heat from accumulating in the connecting tube 311. This can improve the smoothness of the airflow, facilitate heating of the material, and improve the dryness of the material.

[0042] In addition, by arranging the baffle 314 between the barrel 100 and the heating element 312, the material can be prevented from directly contacting the heating element 312, preventing the heating element 312 from melting the material, and improving the reliability of the injection molding machine feeding device.

[0043] Specifically, refer to Figure 2 The heating mechanism 300 further includes a stirring assembly 330, which includes a driving member 331, a rotating shaft 332, and a stirring paddle 333. The rotating shaft 332 is rotatably connected to the barrel 100, and the stirring paddle 333 is fixedly connected to the rotating shaft 332. The driving member 331 is used to drive the rotating shaft 332 to rotate. The rotating shaft 332 is rotatably connected to the barrel 100, and the stirring paddle 333 is fixedly connected to the rotating shaft 332. The rotating shaft 332 is driven to rotate by the driving member 331 so that the stirring paddle 333 can stir the material in the barrel 100, thereby adjusting the position of the material in the barrel 100 and preventing the material from clogging the connecting pipe 311. This allows the material in the barrel 100 to be evenly heated, facilitates drying of the material, and improves processing quality.

[0044] It is understandable that, referring to Figure 1 and Figure 2 The outlet end of the exhaust pipe 320 is detachably connected to a filter 321 for absorbing water vapor. The filter 321 is detachably connected to the exhaust pipe 320 and can conveniently absorb water vapor evaporated from the material through the filter 321. This prevents the water vapor discharged from the exhaust pipe 320 from condensing and dripping onto the barrel 100, preventing the material from re-moistening and improving the ease of use of the injection molding machine's loading device.

[0045] It should be noted that the filter 321 is detachably connected to the exhaust pipe 320, which makes it easy to replace the filter 321 and continuously collect the water vapor discharged from the exhaust pipe 320, thereby improving the ease of use of the injection molding machine feeding device.

[0046] The filter 321 can be fixedly connected to the exhaust pipe 320 by means of fasteners, snap connections, etc., which will not be described in detail here.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
