Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an injection molding machine feed filter device. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are divided into vertical, horizontal, and all-electric types. Injection molding machines can heat plastics and apply high pressure to molten plastics, causing them to be injected and fill the mold cavity.

[0003] When using an injection molding machine, the raw material is placed into the hopper and then enters the heating cylinder of the injection molding machine. The heater heats the plastic raw material, causing it to gradually melt into injectable molten plastic. However, in actual use, this process does not filter and remove impurities, large particles, or dust from the raw material, resulting in poor quality of the injection molded parts. Utility Model Content

[0004] In order to solve the problem of poor quality of injection molded parts caused by the failure to filter and remove impurities, large particles or dust in the raw materials during actual use; the purpose of this utility model is to provide a feed filtration device for injection molding machines.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-5 As shown, this utility model provides a feeding filter device for an injection molding machine, including an injection molding machine body 1. A fixed frame 2 is provided on the upper part of the injection molding machine body 1. A housing 3 is provided in the middle of the fixed frame 2. A filter plate 33 is rotatably installed in the middle of the housing 3. Two sets of symmetrically distributed toothed plates 37 are fixedly installed on one side of the housing 3. A rotating shaft 381 is rotatably installed on one side of the fixed frame 2. A drive assembly is provided on one side of the rotating shaft 381. Two symmetrically distributed half-face gears 382 are fixedly installed in the middle of the rotating shaft 381. The two half-face gears 382 are meshed with the toothed plates 37. A push frame 36 is fixedly installed in the middle of the other side of the housing 3. A spring 35 is fixedly installed on one side of the push frame 36. A housing 34 is fixedly installed in the middle of one side of the fixed frame 2. The middle of the push frame 36 slides through one side of the housing 34. One end of the spring 35 is fixedly installed on the inner wall of the housing 34.

[0020] A dust-collecting plate 41 is fixedly installed on the lower part of the housing 3. A cavity 42 is opened in the middle of the dust-collecting plate 41. A vacuum cleaner 4 is fixedly installed on one side of the top of the fixing frame 2. The input end of the vacuum cleaner 4 is fixedly installed on one side of the dust-collecting plate 41. The cavity 42 and the input end of the vacuum cleaner 4 are interconnected. A rubber belt 32 is fixedly installed on the bottom of the housing 3. A hopper 31 is fixedly installed on the bottom of the rubber belt 32. The bottom of the hopper 31 is fixedly installed on one side of the top of the injection molding machine body 1.

[0021] A worm gear 332 is rotatably mounted on one side of the upper part of the housing 3, and a worm 333 is rotatably mounted on the side of the housing 3 near the worm gear 332. The worm 333 is meshed with the worm gear 332. One end of the filter plate 33 is fixedly mounted on one side of the middle part of the worm gear 332. By setting the worm gear 332 and the worm 333, the structure has a self-locking function, which makes it more convenient to clean the filter plate 33 after the angle is adjusted, and it will not reset due to gravity.

[0022] The drive assembly includes a motor 38, the bottom of which is fixedly mounted on the upper side of the mounting bracket 2, and one end of the rotating shaft 381 is fixedly mounted on the drive end of the motor 38. By setting the motor 38, the rotating shaft 381 can be driven to rotate.

[0023] Two symmetrically distributed limiting rods 22 are fixedly installed in the middle of the fixed frame 2. Both sides of the housing 3 are slidably installed on the outer surface of the limiting rods 22. By setting the limiting rods 22, when the housing 3 is driven by the motor 38 to move back and forth, the two sides of the housing 3 will slide on the outer surface of the limiting rods 22, thereby supporting and limiting the housing 3.

[0024] Two mirror-distributed grooves 331 are provided on the upper side of the housing 3. One side of the filter plate 33 is slidably locked inside the groove 331. By setting the groove 331, the two ends of the filter plate 33 are locked at the bottom of the groove 331 when the filter plate 33 is horizontal, thus supporting it.

[0025] Four evenly distributed support rods 21 are fixedly installed at the bottom of the fixed frame 2. The bottom ends of the four support rods 21 are all fixedly installed on one side of the top of the injection molding machine body 1. By setting the support rods 21, the entire device can be supported.

[0026] Working principle: In actual use, the injection molding raw material is placed into the housing 3. The motor 38 is started to drive the rotating shaft 381 to rotate, which drives the half-face gear 382 to rotate. With the half-face gear 382 and the toothed plate 37 working together, the housing 3 is driven to move back and forth. While the other side of the housing 3 is moving back and forth, the reciprocating movement of the housing 3 is more stable due to the force of the spring 35 and the limiting of the push frame 36 by the box 34. This allows the raw material entering the housing 3 to be shaken, so that the raw material is filtered through the filter plate 33. Impurities and larger raw materials will remain on the upper part of the filter plate 33.

[0027] At the same time, the vacuum cleaner 4 is started. After the raw material passes through the filter plate 33, it will continue to fall down through the gap of the suction plate 41. Under the action of the vacuum cleaner 4, the dust is sucked into the vacuum cleaner 4 through the cavity 42, which can clean the dust in the raw material. By rotating the worm gear 333, the meshing worm wheel 332 is driven to rotate, which causes the filter plate 33 to tilt, so that the impurities slide to one end by gravity, making it easier to clean the impurities at the top.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
