[0020] The following will refer to the attached Figures 1 to 7 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] Embodiment 1: as attached Figure 1 -Attached Figure 7 A feeding mechanism of an injection molding machine for the injection molding production of automobile door handles comprises a feeding shell 1, wherein the feeding shell 1 is arranged at a feeding port of the injection molding machine, and molten plastic particles are poured into the feeding shell 1 from above.

[0022] In the direction of pouring the molten plastic particles: two symmetrically arranged middle plates 5 are provided in the middle position of the feed shell 1, and a feed outlet is formed between the two middle plates 5. The middle plates 5 divide the feed shell 1 from top to bottom into a scattering area and a filtering area. The plastic particles will first enter the scattering area, and then fall into the filtering area under the action of gravity. The scattering area is used to extrude the plastic particles, and the block-like and sticky plastic particles will be broken up during the extrusion process, which is convenient for the subsequent melting process of the plastic particles. The filtering area is used to filter the dust and iron filings mixed in the plastic particles to prevent them from affecting the quality of the final product.

[0023] The breaking-up zone includes a plurality of symmetrically arranged breaking-up blocks 3 connected to the inner side wall of the feed shell 1. The molten plastic particles will be squeezed from top to bottom or from bottom to top in sequence between two symmetrically arranged breaking-up blocks 3, and the molten plastic particles will move downward through the discharge port formed between the two middle plates 5.

[0024] The filtering area includes a collecting frame 22 and a guide rod 24. The guide rod 24 is provided with an electromagnetic rod 26. The electromagnetic rod 26 can drive the adsorbed iron filings to move outside the feed housing 1. The electromagnetic rod 26 is used to filter the iron filings mixed in the molten plastic particles. When the electromagnetic rod 26 is in the feed housing 1, the electromagnetic rod 26 is in a powered state, and its surface is magnetic. When the electromagnetic rod 26 moves to the outside of the feed housing 1 along the guide frame 25, the electromagnetic rod 26 is in a powered-on state and loses its magnetic force. In this way, when the electromagnetic rod 26 loses its magnetic force, the iron filings fall into the installation frame 27 under the action of gravity because they are not affected by the magnetic force.

[0025] Example 2: This example specifically illustrates the process in which the breaking block 3 in Example 1 pushes the plastic particles so that the adhering plastic particles can be dispersed.

[0026] Two symmetrically arranged drainage inclined plates 2 are fixedly connected to the inner side wall near the top of the feed shell 1, and a plurality of the breaking blocks 3 are arranged between the drainage inclined plates 2 and the middle plate 5; Figure 1 The plastic particles poured from the top of the feed housing 1 will be guided by the drainage ramp 2 and moved between the symmetrically arranged scattering blocks 3. And the plastic particles will move down from the position of the discharge port, and the distance of the discharge port is limited, which will slow down the speed of the plastic particles falling. It is convenient for the scattering blocks 3 to push the plastic particles, and refer to the attached Figure 1 The end of the breaking block 3 facing the plastic particles is provided with an insertion block, which is arranged in a triangular manner, and its sharp end is perpendicular to the falling direction of the plastic particles. The block-shaped plastic particles are squeezed and dispersed by moving the insertion block.

[0027] The breaking block 3 is connected to the inner wall of the feed shell 1 through a telescopic column 9. A return spring 10 is sleeved on the outer side of the telescopic column 9. The return spring 10 is used for returning the breaking block 3 after it moves.

[0028] A servo motor 4 is fixedly connected to the inner wall of the feed shell 1 near the top, and an output shaft 6 is fixedly connected to the output end of the servo motor 4. The servo motor 4 can drive the output shaft 6 to rotate in the forward or reverse direction; the servo motors 4 arranged on the two opposite inner walls of the feed shell 1 synchronously drive the corresponding output shafts 6 to rotate.

[0029] The output shaft 6 passes through the scattering area and the filtering area, and a mounting rod 7 is threadedly connected to the outer wall of the output shaft 6 located in the scattering area. A rotating shaft 11 is rotatably connected to the end of the mounting rod 7 close to the scattering block 3, and a rotating frame 13 is fixedly connected to the rotating shaft 11. A plurality of drag reducing pulleys 14 are evenly distributed in a circle on the rotating frame 13. The downward movement of the mounting rod 7 can push the corresponding scattering block 3 to move to the middle position in turn and extrude the particles of the molten plastic; the drag reducing pulley 14 can reduce the friction force when the rotating frame 13 contacts the scattering block 3.

[0030] A pushing rack 8 is provided between the drainage inclined plate 2 and the middle plate 5 , and a pushing gear 12 is fixedly connected to the outer side wall of the rotating shaft 11 , and the pushing gear 12 is meshedly connected with the pushing rack 8 .

[0031] When the servo motor 4 drives the output shaft 6 to rotate in the forward and reverse directions, the mounting rod 7 will move up and down under the action of the thread. Figure 3 , which will drive the rotating frame 13 to move upward, and the rotating frame 13 will rotate synchronously under the cooperation of the pushing rack 8 and the pushing gear 12, and the rotating frame 13 is arranged in a "cross" manner, and its ends will contact the adjacent breaking blocks 3 in turn when rotating, and push the breaking blocks 3 to move in the direction of the plastic particles, thereby squeezing the plastic particles, so that the adhering particles are broken up. It should be noted that the lateral distance moved by the breaking block 3 will not exceed the lateral length of the breaking block, thereby preventing the plastic particles from entering the position directly below the drainage inclined plate 2.

[0032] Embodiment 3: This embodiment is to screen the plastic particles falling into the filtering area to screen out the dust and iron filings mixed in the plastic particles.

[0033] Refer to the attached Figure 2 The collecting frame 22 is arranged in an inverted V shape, and is slidably connected to the inner side wall of the feed shell 1 located below the feed port. A collecting hole 29 is provided on the upper end surface of the collecting frame 22, and the aperture of the collecting hole 29 is smaller than the diameter of the molten plastic particles. The collecting frame 22 collects dust mixed in the molten plastic particles through the collecting hole 29.

[0034] A transmission rod 17 is connected to the bottom of the middle plate 5 through a telescopic rod, and a rotating disc 15 is fixedly connected to the output shaft 6. A plurality of protrusions 16 are provided on the lower end surface of the rotating disc 15. A fixed spring 18 is provided between the collecting frame 22 and the inner side wall of the feed shell 1. The transmission rod 17 is located above the fixed spring 18. When the protrusion 16 drives the transmission rod 17 to move downward, it will squeeze the fixed spring 18.

[0035] Specifically, the plastic particles falling on the collection frame 22 will slide down along the two lower ends of the collection frame 22. During the sliding process, the output shaft 6 will drive the rotating disc 15 to rotate. When the rotating disc 15 rotates, it drives the bump 16 to rotate synchronously. The rotation of the bump 16 will contact the transmission rod 17 and push the transmission rod 17 down a short distance. When the bump 16 released from the transmission rod 17 is separated from the transmission rod 17, the transmission rod 17 will move up again under the action of the fixing spring 18. This is repeated, so that the collection frame 22 can move up and down, thereby achieving a shaking effect, so that the dust adhering to the plastic particles is separated from the plastic particles, and the dust will enter the collection frame 22 through the collection hole 29, thereby completing the dust screening.

[0036] A shaking plate 19 is rotatably connected to the inner wall of the feed shell 1 located in the filtering area. A sliding groove 21 is opened on the shaking plate 19, and a sliding block is arranged in the sliding groove 21. A connecting rod 20 is rotatably connected to the sliding block, and the top end of the connecting rod 20 is fixedly connected to the collecting frame 22.

[0037] Refer to the attached Figure 4 Under normal circumstances, the plastic particles will accumulate in the lower position between the two shaking plates 19, which will cause the plastic particles to accumulate, which is not conducive to the subsequent melting process.

[0038] By setting the connecting rod 20, when the collecting frame 22 moves up and down, the connecting rod 20 will slide in the sliding groove 21, so that the shaking plate 19 can fan. In this way, the falling plastic particles can be given an initial speed, so that the plastic particles will not accumulate in large quantities in the lower position between the two shaking plates 19.

[0039] The inner wall of the filtering area is rotatably connected with a guide shaft 23, the guide shaft 23 and the output shaft 6 are connected by a bevel gear transmission, the guide rod 24 is threadedly connected to the outer wall of the guide shaft 23, and the guide rod 24 is slidably connected to the inner wall of the feed housing 1, and a guide frame 25 is also provided in the filtering area; When the output shaft 6 rotates, the guide shaft 23 is driven to rotate through the bevel gear. When the guide shaft 23 rotates, the guide rod 24 moves along the direction of the guide shaft 23 through the action of the thread.

[0040] An adapting groove 28 is provided on the guide rod 24, and the height of the adapting groove 28 corresponds to the vertical height of the guide frame 25. One end of the electromagnetic rod 26 is slidably connected in the adapting groove 28, and the other end of the electromagnetic rod 26 is slidably connected to the guide frame 25. Refer to the attached Figure 6When the guide rod 24 moves under the driving action of the guide shaft 23, the electromagnetic rod 26 will be driven to move, and the electromagnetic rod 26 is guided by the guide frame 25 during the movement, so that the electromagnetic rod 26 moves along the direction of the guide frame 25. It should be noted that the shape of the guide frame 25 is not unique, but the guide frame 25 should be able to penetrate into the plastic particles accumulated at the bottom of the feed shell 1. Therefore, when the electromagnetic rod 26 moves, it will absorb the iron filings mixed in the plastic particles under the action of magnetic force.

[0041] A dust removal port 30 is provided on the side wall of the filtering area, one end of the guide frame 25 and the guide shaft 23 extend to the outside of the feed shell 1 through the dust removal port 30, and a mounting frame 27 is provided below the dust removal port 30, wherein the stacking height of the molten plastic particles will not be higher than the height of the dust removal port 30.

[0042] It should be noted that the forward and reverse rotation of the output shaft 6 in the scattering area will also drive the guide shaft 23 to rotate forward and reverse synchronously, and the up and down movement of the installation rod 7 corresponds to the forward and backward movement of the guide rod 24. When the electromagnetic rod 26 passes through the impurity removal port 30 and moves to the outside of the feed shell 1, the electromagnetic rod 26 will be powered off and lose its magnetic force, so that the adsorbed iron filings fall into the installation frame 27, which is convenient for collecting the doped iron filings. It should also be noted that in the attached Figure 7 In the embodiment, the impurity removal port 30 is also provided with a groove for the guide rod 24 to pass through. The guide rod 24 can move to the outside of the shell through the groove, thereby driving the electromagnetic rod 26 to move to the outside of the shell, thereby supplementing the distance moved by the guide rod 24 when the electromagnetic rod 26 moves along the guide frame 25 to the outside of the feed shell 1.
