Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a quantitative feeding device for processing plastic granules. Background Technology

[0002] Modified plastics refer to plastic products that have been modified from general-purpose plastics and engineering plastics through methods such as filling, blending, and reinforcement, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness. During processing and production, to prevent the equipment from feeding too quickly, which could lead to excessive accumulation of some raw materials and uneven mixing, a quantitative feeding device is needed to control the feeding speed.

[0003] Chinese patent discloses a modified plastic feeding device with adjustable discharge position (authorization announcement number CN221953691U). This patented technology sets up multiple conveying components to form multiple independent storage spaces on the conveyor belt, avoiding the accumulation of a large amount of modified plastic during transportation. The discharge position and height are adjustable by setting up discharge components.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the existing technology, the variable feed flow rate during the processing of plastic granules may lead to problems such as raw material accumulation or insufficient raw material during the melting and extrusion process, resulting in problems such as product uniformity and dimensional accuracy. If the feed rate needs to be manually adjusted by the user, it may lead to low equipment operating efficiency, which not only increases the labor intensity of the user, but also reduces the level of production automation. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of not being able to control the feed flow of the processing equipment, which leads to excessive accumulation of raw materials and affects the final quality of the product. To this end, we propose a quantitative feeding device for plastic granule processing.

[0006] To achieve the above objectives, this application adopts the following technical solution: a quantitative feeding device for processing plastic granules, comprising a first outer shell, a first flow channel fixedly connected to one end of the top of the first outer shell, a first hopper fixedly connected to the top of the first flow channel, a first chute provided inside the first hopper, a first baffle slidably connected to the inner wall of the first chute, a plurality of first limiting grooves provided on both sides of the first baffle, and first limiting blocks rotatably connected to both sides of the first hopper via a rotating shaft, one end of the first limiting block being slidably connected to the inner wall of the first limiting groove.

[0007] Preferably, a second sliding groove is provided on both sides of the first hopper, a first sliding rod is installed inside the second sliding groove, a first limiting buckle is slidably connected to the surface of the first sliding rod, and the inner wall of the first limiting buckle is slidably connected to the surface of the first limiting block.

[0008] Preferably, a first spring is fixedly connected to one side of the first limiting buckle, and one end of the first spring is fixedly connected to one side of the inner wall of the second slide groove.

[0009] Preferably, a first screen is installed inside the first hopper.

[0010] Preferably, the inner wall of the first hopper is provided with a first inclined surface.

[0011] Preferably, a drive motor is installed on the top of the first outer casing, and a stirring blade is installed at the output end of the drive motor.

[0012] Preferably, a first grinding roller brush is installed at the output end of the drive motor.

[0013] Technical effects and advantages of this utility model:

[0014] In this invention, the user controls the flow rate of plastic granules in the first hopper into the first outer shell through the first flow channel by moving the first baffle outward. After the user adjusts the metering, the first limiting block is rotated so that one end of the first limiting block is inserted into the inner wall of the first limiting groove, thus fixing the position of the first baffle. By fixing the position of the first baffle when the first limiting block is inserted into the inner wall of the corresponding first limiting groove, the flow rate of the feed can be limited, thereby achieving the purpose of metering the feed. Moreover, the device has a simple structure, is easy to operate, reduces the complexity and labor intensity of manual operation, and improves the safety and flexibility of the production process.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a quantitative feeding device for processing plastic granules, including a first outer shell 1, a first flow channel 2 fixedly connected to one end of the top of the first outer shell 1, a first hopper 3 fixedly connected to the top of the first flow channel 2, a first chute 4 opened inside the first hopper 3, a first baffle 5 slidably connected to the inner wall of the first chute 4, and several first limiting grooves 6 opened on both sides of the first baffle 5. First limiting blocks 7 are rotatably connected to both sides of the first hopper 3 via a rotating shaft, and one end of the first limiting block 7 is slidably connected to the inner wall of the first limiting groove 6. When the user puts plastic granules into the feed port of the first hopper 3, the user can then rotate the first limiting block 7 to move it out from the inner wall of the first limiting groove 6. The position restriction of the first baffle 5 is released. The user controls the flow rate of plastic particles in the first hopper 3 through the first flow channel 2 into the first outer shell 1 by moving the first baffle 5 outward. After the user adjusts the metering, the position of the first baffle 5 is fixed when the first limiting block 7 is rotated so that one end of the first limiting block 7 is inserted into the inner wall of the first limiting groove 6. By fixing the position of the first baffle 5 when the first limiting block 7 is inserted into the inner wall of the corresponding first limiting groove 6, the flow rate of the feed can be restricted to achieve the purpose of metering the feed. The device has a simple structure and is easy to operate, reducing the complexity and labor intensity of manual operation and improving the safety and flexibility of the production process. The first hopper 3 has second sliding grooves 8 on both sides. The interior of the second sliding grooves 8 is equipped with... The device is equipped with a first sliding rod 9, and a first limiting buckle 10 is slidably connected to the surface of the first sliding rod 9. The inner wall of the first limiting buckle 10 is slidably connected to the surface of the first limiting block 7. When the user inserts one end of the first limiting block 7 into the inner wall of the first limiting groove 6, the user moves the first limiting buckle 10 forward by moving the first sliding rod 9 inside the second sliding groove 8, thereby restricting the position of the first limiting block 7 and preventing it from rotating outward. The first limiting buckle 10 makes the insertion of the first limiting block 7 into the first limiting groove 6 more secure, thus improving the stability of the device. A first spring 11 is fixedly connected to one side of the first limiting buckle 10, and one end of the first spring 11 is fixedly connected to one side of the inner wall of the second sliding groove 8. When the first limiting buckle 10 slides along the surface of the first sliding rod 9, the first limiting buckle 10 compresses the first spring 11, causing the first spring 11 to store force and contract. When the user needs the first limiting buckle 10 to return to its original position, the first limiting buckle 10 is released. At this time, the first spring 11 releases and rebounds, pushing the first limiting buckle 10 back to its original position. The first spring 11 enables the first limiting buckle 10 to have an automatic reset function and reduces the user's operation steps on the device. The first hopper 3 is equipped with a first screen 12. When the user pours plastic granules into the inside of the first outer shell 1 through the feed port of the first hopper 3, the first screen 12 can screen out deformed plastic granules or impurities and leave them on the surface of the first screen 12, thereby improving the quality of the final product in subsequent processing.

[0023] Reference Figure 1 , Figure 2 and Figure 5 As shown in this embodiment: the inner wall of the first hopper 3 is provided with a first inclined surface 13, which allows the plastic granules poured from the first hopper 3 to enter the interior of the first outer shell 1 more smoothly. The first inclined surface 13 can maintain the flow rate of the plastic granules entering the interior of the first outer shell 1, preventing the first hopper 3 from becoming blocked. A drive motor 14 is installed on the top of the first outer shell 1, and a stirring blade 15 is installed at the output end of the drive motor 14. When the plastic granules enter the interior of the first outer shell 1, the drive motor 14 drives the stirring blade 15 to stir the plastic granules inside the first outer shell 1. Additives can be added from the first hopper 3, and the mixing of plastic particles and atomizing additives is promoted by the stirring blade 15. This not only improves the mixing efficiency, but also ensures that the modification of plastic particles is uniform and stable. The addition of the stirring function can also reduce product defects caused by uneven mixing and improve the continuity of the production process. The output end of the drive motor 14 is equipped with a first grinding roller brush 16. The metal wire on the surface of the first grinding roller brush 16 grinds the surface of the plastic particles inside the first outer shell 1 and removes burrs, so that the processed plastic particles have no irregular edges and burrs, making the particles smoother and more regular, and improving the quality of the final product.

[0024] Working principle:

[0025] Step 1: The user pours plastic granules into the first hopper 3 through the inlet, rotates the first limiting block 7 to move it out of the inner wall of the first limiting groove 6, releases the position restriction of the first baffle 5, and then adjusts the first baffle 5 to move outward, controlling the flow rate of plastic granules into the first outer shell 1 through the first flow channel 2, thus achieving quantitative feeding. After adjustment, the first limiting block 7 is rotated back to its original position, so that one end is inserted into the inner wall of the first limiting groove 6, fixing the position of the first baffle 5 and limiting the feeding flow. The first limiting buckle 10 is moved forward by the first sliding rod 9 in the second sliding groove 8, fixing the position of the first limiting block 7 and enhancing the stability of the device. When the first limiting buckle 10 slides along the first sliding rod 9, it compresses the first spring 11 to store force. After release, the first spring 11 automatically rebounds, causing the first limiting buckle 10 to reset, simplifying the operation steps. The first screen 12 filters out deformed plastic granules or impurities, improving product quality.

[0026] Step two: The user pours plastic granules into the first hopper 3 through the inlet. The first inclined surface 13 on the inner wall of the first hopper 3 allows the plastic granules to flow smoothly into the first outer shell 1. This inclined surface design helps maintain the flow rate of the plastic granules and prevents hopper blockage. After the plastic granules enter the first outer shell 1, the drive motor 14 will start and drive the stirring blade 15 to stir the plastic granules inside. The user can add additives. The stirring action of the stirring blade 15 promotes the mixing of plastic granules and atomizing additives, improves mixing efficiency, and ensures the uniformity and stability of plastic granule modification, reducing product defects caused by uneven mixing. Then, the metal wire of the first grinding roller brush 16 grinds the surface of the plastic granules inside the first outer shell 1 to remove burrs, etc., making the edges of the processed plastic granules smooth and regular, further improving the quality of the final product.
