Technical Field

[0001] The utility model belongs to the technical field of injection molding, and relates to a particle feeding device, in particular to a raw material particle feeding device for injection molding of a ball seat fixer. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and complex-shaped products and other molding and processing fields.

[0003] When loading the injection molding machine in the prior art, the granular raw materials need to be transported to the hopper of the injection molding machine. However, most of the granular raw materials are not subjected to metal removal treatment during transportation, resulting in metal contamination in the raw materials and causing clogging of the injection molding machine.

The utility model can adsorb the iron debris remaining in the plastic granules, so as to achieve the purpose of removing the iron debris remaining in the plastic granules, and can avoid the occurrence of the undesirable phenomenon that the iron debris enters the injection molding machine and causes damage to the injection molding machine.

[0005] However, in this patent, the cylindrical permanent magnet needs to be disassembled each time the iron filings attached to the cylindrical permanent magnet are removed, and then reinstalled after the removal is completed, which is very cumbersome and inconvenient, making it impossible to quickly and conveniently remove the iron debris remaining in the particles.

DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] like Figure 1-Figure 3As shown, a raw material particle feeding device for ball seat holder injection molding includes a hopper 1 and a feeding rack 2 fixed to the bottom of the hopper 1, a feeding channel 3 is vertically opened at the center of the feeding rack 2, the top of the feeding channel 3 is connected to the discharge end of the hopper 1, a magnetic ring block 4 is fixed in the feeding channel 3, a cleaning ring block 5 that slides up and down is arranged on the top of the magnetic ring block 4, the inner ring surface of the magnetic ring block 4 is in contact with the outer ring surface of the cleaning ring block 5, an iron chip collecting chamber 6 is opened in the feeding rack 2 and is located on the bottom side of the magnetic ring block 4, and a sealing component 16 is arranged between the iron chip collecting chamber 6 and the magnetic ring block 4.

[0029] During operation, the iron filings contained in the raw material particles in the feeding channel 3 are adsorbed by the magnet ring block 4, and then the iron filings adsorbed on the magnet ring block 4 are pushed into the iron filing collection chamber 6 by the cleaning ring block 5 which slides up and down to complete the cleaning.

[0030] A guide slot 7 is vertically provided in the feeding channel 3, and the guide slot 7 is slidably matched with the extended part of the cleaning ring block 5, and a guide rod 8 is vertically fixed to the extended part of the cleaning ring block 5. A servo motor 9 located on one side of the guide rod 8 is fixed in the feeding frame 2, and the output shaft end of the servo motor 9 is coaxially fixedly connected with a driving gear 10, and the driving gear 10 is meshed with the tooth segments arranged on the guide rod 8 for transmission.

[0031] With the above structure, the servo motor 9 can drive a series of components to allow the cleaning ring block 5 to automatically complete the up and down sliding action, thereby further achieving the effect of automatically cleaning iron filings and improving the cleaning efficiency.

[0032] A spring 11 is arranged in the guide slot 7 , one end of the spring 11 is fixedly connected to the slot bottom of the guide slot 7 , and the other end of the spring 11 is fixedly connected to the extending parts on both sides of the cleaning ring block 5 .

[0033] With the above structure, a spring 11 can be arranged in the guide slot 7 to play a role of buffering and shock absorption, so that the sliding process of the cleaning ring block 5 is smoother and more stable.

[0034] The sealing component includes an iron chip inlet 13 opened between the iron chip collection chamber 6 and the feeding channel 3, and a plurality of material blocking movable plates 14 hinged to the iron chip inlet 13. The bottom end of the cleaning ring block 5 can penetrate the iron chip inlet 13. A torsion spring is built into the hinge of the material blocking movable plate 14, and the plurality of material blocking movable plates 14 form an annular sealing valve structure.

[0035] By adopting the above structure, the iron chip inlet 13 can be sealed by the material blocking movable plate 14 with a built-in torsion spring, so that during the raw material particle feeding process, the raw material particles will not fall from the iron chip inlet 13 into the iron chip collecting chamber 6, and the normal pushing of the cleaning ring block 5 will not be hindered when the adsorbed iron chips are cleaned after the feeding is completed.

[0036] An outer wall of the loading rack 2 is provided with an iron chip cleaning port 15 communicating with the iron chip collecting chamber 6 .

[0037] With the above structure, the iron filings accumulated in the iron filings collecting chamber 6 can be cleaned more conveniently and quickly by opening the iron filings cleaning port 15, thereby improving the overall cleaning effect.

[0038] A dust cover plate 12 is hinged on the top of the hopper 1 .

[0039] With the above structure, the unused hopper 1 can be covered by the dustproof cover plate 12 to prevent the entry of foreign debris and dust.

[0040] The working principle of the utility model is as follows: the raw material particles required for injection molding are poured into the hopper 1. At this time, the raw material particles will pass through the feeding channel 3. When passing through the feeding channel 3, the iron filings contained in the raw material particles will be adsorbed by the magnetic ring block 4. When the feeding is completed, the servo motor 9 can be started. After the servo motor 9 is started, it will drive the driving gear 10 coaxially connected with it to rotate. After the driving gear 10 rotates, it will drive the guide rod 8 to slide up and down through the transmission meshing between the tooth segments arranged on one of the guide rods 8, and further drive the cleaning ring block 5 to slide up and down. When the cleaning ring block 5 slides, its bottom end will push the iron filings adsorbed on the magnetic ring block 4 into the iron filing inlet 13. At this time, the iron filings are distanced from the magnetic ring block 4, so that the iron filings lose their adsorption force and fall into the iron filing collection chamber 6. When the iron filing collection chamber 6 is full, the iron filings accumulated in the iron filing collection chamber 6 can be taken out through the iron filing cleaning port 15 to complete the cleaning of the iron filings.

[0041] In summary, the purpose of removing the iron debris remaining in the particles more conveniently and quickly is achieved, and the undesirable phenomenon of iron debris entering the injection molding machine and causing damage to the injection molding machine is avoided.

[0042] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
