[0030] Please see Figure 1-5A feeding device for automotive headlight injection molding includes a crushing box 1 and a cleaning box 2. A feeding pipe 3 is provided at the bottom of the crushing box 1. A filter screen 4 is installed inside the crushing box 1. A crushing mechanism is installed on the crushing box 1. The cleaning box 2 is installed on top of the crushing box 1 and is connected to the crushing box 1 via a connecting pipe 5. A guide plate 6 is provided on the inner side of the cleaning box 2. A feeding port 7 is provided at the top of the cleaning box 2 above the guide plate 6. An electromagnet 8 is installed at the inner end of the cleaning box 2 away from the guide plate 6, located above the guide plate 6. A through groove 9 is provided on the side of the cleaning box 2 below the electromagnet 8. A collecting box 10 is slidably arranged inside the through groove 9. Two first fixing plates 11 are fixedly connected to the side of the collecting box 10. Two second fixing plates 12 are fixedly connected to the side of the cleaning box 2. Electric cylinders 13 are installed on both second fixing plates 12. The extension rods of the two electric cylinders 13 are fixedly connected to the two first fixing plates 11 respectively. U-shaped bars 23 are fixedly connected to both sides of the side of the box 2 located on both sides of the collection box 10. Sliding blocks 24 are slidably installed inside the two U-shaped bars 23. The side ends of the two sliding blocks 24 are fixedly connected to the side ends of the collection box 10, which plays a role in stabilizing the collection box 10. Limiting plates 25 are installed on the side ends of the two U-shaped bars 23, which play a role in limiting the sliding blocks 24 and the collection box 10, preventing the collection box 10 from sliding out of the through groove 9. A waste discharge port 26 is provided on the bottom end of the collection box 10 away from the impurity removal box 2. A waste discharge pipe 27 communicating with the waste discharge port 26 is connected to the bottom end of the collection box 10. A first guide seat 28 is fixedly connected inside the collection box 10. Iron metal impurities falling into the collection box 10 are discharged through the waste discharge pipe 27. A waste collection box 29 is placed below the waste discharge pipe 27 to facilitate the collection of metal impurities in the raw materials. A conveying mechanism is provided on the side of the crushing box 1 and the impurity removal box 2. The output end of the conveying mechanism extends into the inside of the feed port 7.

[0031] In this embodiment, after the raw material for the automotive headlight injection molding falls onto the guide plate 6 and slides off, the electromagnet 8 removes iron impurities from the raw material by attracting them. This prevents metal materials from mixing in and affecting the structure of the plastic part, and also prevents iron impurities from clogging and damaging the automotive headlight injection molding machine. When it is necessary to clean the iron impurities on the electromagnet 8, the electric cylinder 13 pulls the collection box 10 to move it into the impurity removal box 2. Then, the power supply to the electromagnet 8 is disconnected, and the iron impurities on the electromagnet 8 fall into the collection box 10 due to gravity. The iron impurities in the collection box 10 then fall into the impurity collection box 29 through the impurity discharge port 26 and the impurity discharge pipe 27. The impurity collection box 29 then removes the iron impurities. Impurities are collected. After the iron impurities on the electromagnet 8 have all fallen off, the power supply to the electromagnet 8 is turned on. Then, the electric cylinder 13 pushes the collection box 10 to the outermost side. At this time, the outer wall of the collection box 10 is flush with the inner wall of the impurity removal box 2. The filter screen 4 facilitates the interception of larger particles in the raw material. At the same time, the crushing mechanism crushes the larger particles on the filter screen 4 to prevent them from entering the interior of the car light injection molding machine. This ensures the uniformity of the molten state of the raw material, guarantees the quality of the car light injection molding, and improves its practicality. The conveying mechanism facilitates the transport of raw materials from a lower position to the interior of the impurity removal box 2 at a higher position. This avoids the danger of people climbing to add raw materials and adds them from a lower position, improving the efficiency of adding raw materials.

[0032] Please see Figure 2 The crushing mechanism includes a first motor 14, which is fixedly installed on the top of the crushing box 1. The output end of the first motor 14 is fixedly connected to a first rotating shaft 15. Multiple crushing blades 16 are installed on the bottom side of the first rotating shaft 15, and the bottom ends of the multiple crushing blades 16 are in contact with the top of the filter screen plate 4.

[0033] In this embodiment, the first motor 14 drives the first rotating shaft 15 to rotate, and the first rotating shaft 15 drives multiple crushing blades 16 to rotate, thereby crushing larger particles on the filter screen plate 4.

[0034] Please see Figure 1 and Figure 5 The material conveying mechanism includes a second motor 17 and a storage box 18. The storage box 18, the crushing box 1 and the impurity removal box 2 are all fixedly installed with a second guide seat 30 to facilitate the flow of raw materials. The bottom side of the storage box 18 is connected to a conveying pipe 19, and the top side of the conveying pipe 19 is connected to a discharge pipe 20. The other end of the discharge pipe 20 extends into the inside of the feed inlet 7. The second motor 17 is fixedly installed at the top of the conveying pipe 19. The output end of the second motor 17 is fixedly connected to a second rotating shaft 21, and the outside of the second rotating shaft 21 is fixedly connected to a spiral blade 22.

[0035] In this embodiment, the raw material for the car headlight injection molding is added into the storage box 18. The raw material inside the storage box 18 flows to the bottom of the conveying pipe 19. The second motor 17 drives the second rotating shaft 21 and the spiral blade 22 to rotate, conveying the raw material inside the bottom of the conveying pipe 19 to the upper side of the conveying pipe 19, and then falling onto the guide plate 6 through the discharge pipe 20.

[0036] In summary, when using the overall equipment:

[0037] The raw material for the car headlight injection molding is added into the storage bin 18. The raw material inside the storage bin 18 flows to the bottom of the conveying pipe 19. The second motor 17 drives the second rotating shaft 21 and the spiral blade 22 to rotate, conveying the raw material from the bottom of the conveying pipe 19 to the upper side of the conveying pipe 19. The raw material falls onto the guide plate 6 through the discharge pipe 20. The raw material slides off the guide plate 6. During the process of the raw material sliding off the guide plate 6, the electromagnet 8 removes iron impurities from the raw material by attracting them. The removed raw material falls into the crushing box 1 through the connecting pipe 5. The filter screen 4 intercepts larger particles of the raw material. The first motor 14 drives the first rotating shaft 15 to rotate. The first rotating shaft 15 drives multiple crushing blades 16 to rotate. The multiple crushing blades 16 crush the larger particles of the raw material on the filter screen 4. The raw material falling into the impurity removal box 2 enters the interior of the car headlight injection molding machine below through the feed pipe 3.
