Description

Technical Field

[0001] This utility model relates to the field of plastic screening technology, specifically a screening device for the production of antibacterial amino molding compounds. Background Technology

[0002] Antimicrobial amino molding compound is a type of plastic material with antimicrobial properties. It typically prevents the growth of bacteria and microorganisms by adding antimicrobial agents or using special formulations. This material is commonly used in products requiring cleanliness and hygiene, such as medical devices, kitchen utensils, and electronic product casings. Antimicrobial amino molding compound granules are the raw material form of this material; they are usually processed plastic granules with added antimicrobial agents or other components to enhance antimicrobial properties. These granules can be processed through injection molding, extrusion, and other techniques to produce final products with antimicrobial properties.

[0003] Chinese patent CN222451015U discloses a plastic granule screening device, including a pelletizer. The pelletizer has a base on its side and a feed hole on the top of the base. This utility model provides a plastic granule screening device that allows for easy adjustment of the position of the feed structure of the screening device, thereby adapting to pelletizers that process different plastic granules and increasing the convenience of connection.

[0004] The aforementioned and similar prior art generally uses a vibrating screening device for screening. The screening holes of the screen gradually increase in size, which can easily lead to some smaller diameter plastic particles not being screened out and falling through the larger diameter screening holes along with the larger diameter plastic particles, thus reducing the screening effect.

[0005] Therefore, this utility model provides a screening device for the production of antibacterial amino molding compounds that can fully screen plastic particles. Utility Model Content

[0006] To address the problem in existing technologies where smaller plastic particles fall through larger screening holes along with larger particles, a screening device for the production of antibacterial amino molding compounds has been designed.

[0008] Furthermore, a support frame is fixedly installed on the top of the bracket frame, and the top of the support frame is fixedly connected to the bottom of the fixed cylinder.

[0009] Furthermore, a bent pipe is installed through the top of the fixed cylinder. One end of the bent pipe is connected to the inner side of the screen ring with the smallest diameter, and a feed hopper is fixedly installed at the other end of the bent pipe. The feed hopper is connected to the inner side of the fixed cylinder through the bent pipe.

[0010] Furthermore, a geared motor is fixedly installed on the side of the fixed cylinder near the bend.

[0012] Furthermore, a movable groove is provided on one side of the inner wall of the discharge hole, and multiple limiting holes are provided through the bottom of the fixed cylinder, and the limiting holes are respectively connected to the movable groove.

[0013] Furthermore, a sealing plate is slidably placed on the inner side of the movable groove, and a push rod is fixedly installed on one side of the sealing plate, with the push rod passing through and located inside the limiting hole.

[0014] The beneficial effects of this utility model are:

[0015] (1) The screening device for the production of antibacterial amino molding compound described in this utility model adopts an inclined rotating drum design.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example: Figures 1-5 As shown, the screening device for producing antibacterial amino molding compounds according to this utility model includes a support frame 1, a fixed cylinder 3 fixedly installed on the top of the support frame 1, the fixed cylinder 3 being placed at an incline, a support frame 2 fixedly installed on the top of the support frame 1, the top of the support frame 2 being fixedly connected to the bottom of the fixed cylinder 3, a rotating cylinder 7 being rotatably installed on the inner side of the fixed cylinder 3, a plurality of discharge holes 10 being opened at the bottom of the fixed cylinder 3, a bent pipe 4 being installed through the top of the fixed cylinder 3, one end of the bent pipe 4 communicating with the inner side of the screen ring 9 with the smallest diameter, and a feed hopper 5 being fixedly installed on the other end of the bent pipe 4, the feed hopper 5 communicating with the inner side of the fixed cylinder 3 through the bent pipe 4.

[0026] Specifically, the bracket frame 1 and the support frame 2 can provide stable support for the fixed cylinder 3, the fixed cylinder 3 can provide rotation space for the rotating cylinder 7, the fixed cylinder 3 can provide through opening space for the discharge hole 10, the discharge hole 10 can provide a channel for the plastic particles inside the fixed cylinder 3 to the outside, and the bent pipe 4 and the feed hopper 5 can provide a channel for the plastic particles outside to enter the inside of the fixed cylinder 3.

[0027] In this embodiment, a geared motor 6 is fixedly installed on the side of the fixed cylinder 3 near the bend 4. The output end of the geared motor 6 is fixedly connected to the top of the rotating cylinder 7 through the interior of the fixed cylinder 3 via a bearing. Multiple feed holes 8 are provided through the top of the rotating cylinder 7. The multiple feed holes 8 are arranged in a circle with the output end of the geared motor 6 as the center. Multiple screen rings 9 are fixedly installed on the inner side of the rotating cylinder 7. The diameter of the multiple screen rings 9 gradually increases from the inside to the outside. Screening holes are provided through the interior of the screen rings 9. The larger the diameter of the screen rings 9, the smaller the diameter of the screening holes.

[0028] Specifically, the fixed cylinder 3 provides stable support for the geared motor 6, the geared motor 6 provides rotational driving force for the rotating cylinder 7, and the rotating cylinder 7 provides through-hole space for multiple feed holes 8, allowing plastic particles to enter the inner side of the fixed cylinder 3 through the feed hopper 5 and the bend 4. The plastic particles pass through the feed holes 8 into the inner side of the rotating cylinder 7, so that the plastic particles are located inside the screen ring 9 with the smallest diameter. The rotating cylinder 7 provides stable support for multiple screen rings 9, so that when the rotating cylinder 7 rotates, it can drive the screen rings 9 to rotate. The screen rings 9 cooperate with the inner side of the bottom wall of the fixed cylinder 3 to drive the plastic particles to turn over, so that the plastic particles flow for screening. When the plastic particles are located inside the screen ring 9 with the smallest diameter, plastic particles smaller than the diameter of the screening hole pass through the screen ring 9 and fall down to the inner side of the second smallest diameter screen ring 9, and so on, to gradually screen. The smaller the diameter of the screen ring 9, the larger the diameter of the plastic particles at the screening point.

[0029] In this embodiment, a triangular tube 11 is fixedly installed at the bottom of the fixed cylinder 3. Multiple discharge pipes 12 are opened through the inside of the triangular tube 11, and the discharge pipes 12 correspond one-to-one with the discharge holes 10. A movable groove 13 is opened on one side of the inner wall of the discharge hole 10. Multiple limiting holes 14 are opened through the bottom of the fixed cylinder 3, and the limiting holes 14 are respectively connected to the movable grooves 13. A sealing plate 15 is slidably placed on the inner side of the movable groove 13. A push rod 16 is fixedly installed on one side of the sealing plate 15, and the push rod 16 passes through and is located inside the limiting hole 14.

[0030] Specifically, the fixed cylinder 3 provides stable support for the triangular tube 11, the triangular tube 11 provides a through opening for the discharge pipe 12, the discharge pipe 12 provides a channel for the plastic particles to flow to the outside, the triangular tube 11 ensures that the horizontal position of plastic particles of different diameters is the same when they are discharged, preventing larger diameter plastic particles from falling from a higher position, the sealing plate 15 seals the discharge hole 10, and the push rod 16 drives the sealing plate 15 to move, which can easily rotate to discharge plastic particles of different diameters individually.

[0031] Working principle: The operator first starts the geared motor 6, which drives the rotating drum 7 to rotate. Then, the operator pours plastic granules into the feed hopper 5, allowing the granules to pass through the feed hopper 5 and the curved pipe 4 into the inner side of the fixed cylinder 3. The plastic granules pass through the feed hole 8 into the inner side of the rotating drum 7, placing them inside the smallest diameter screen ring 9. At this point, plastic granules smaller than the screening hole diameter pass through this screen ring 9 and fall down to the inner side of the second smallest diameter screen ring 9, and so on, gradually screening the granules. The smaller the diameter of the screen ring 9, the lower the screen ring 9 becomes. The larger the diameter of the plastic particles on the side, the more the screen ring 9 rotates under the action of the rotating drum 7, which flips the plastic particles inside the screen ring 9 to improve the screening effect. When the staff needs to feed plastic particles of a certain diameter, they can grab the push rod 16 and push it to one side, so that the push rod 16 drives the sealing plate 15 to release the seal on the discharge hole 10, so that the plastic particles inside the screen ring 9 of that diameter can flow out to the outside through the discharge hole 10 and the discharge pipe 12 under their own gravity, which makes it convenient to collect plastic particles of different diameters separately.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
