Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, specifically to a device for melting recycled plastic granules. Background Technology

[0002] Recycled plastic pellets are made from waste plastics. They are produced from discarded plastic products and have a broad market. Plastic recycling can reduce plastic waste pollution, turn waste into treasure, and create huge economic and social benefits.

[0003] A search revealed Chinese patent publication number CN222079767U, which discloses a plastic granule melting device. In this patent, a heater heats the hot melt box, heating the feeding seat. Then, a roller rotates, causing a baffle to rotate to the lower opening of the feeding seat, sealing it and allowing material to be poured into the feeding seat. The material is preheated within the feeding seat. After preheating, the roller rotates again, causing the baffle to rotate to one side of the feeding seat opening, allowing the material to fall into the hot melt box. This ensures sufficient preheating of the plastic granules, preventing them from falling into the hot melt box due to insufficient preheating. Simultaneously, the rotating shaft causes the heating plate to rotate, which in turn causes the heating rod to rotate, preheating the material in the feeding seat. The rotation of the heating plate also drives a scraper to rotate, scraping off the plastic granules adhering to the inner wall of the feeding seat. This effectively removes the plastic granules adhering to the inner wall of the feeding seat, preventing them from affecting its normal use. However, when the above-mentioned device is used, although the plastic particles to be melted are preheated, different plastic particles are of different sizes. Some larger particles are only preheated on the surface after the device is used, so they are difficult to melt quickly after falling into the hot melt box. Secondly, the plastic particles falling through the feed seat usually accumulate at the falling position. Even if they are stirred by the stirring structure, the interior of the accumulated part is still difficult to melt quickly. Utility Model Content

[0004] This invention proposes a recycled plastic pellet melting device, which has the advantages of prioritizing the crushing of larger pellets before melting to facilitate rapid subsequent melting, and the dispersion and falling of plastic pellets into the melting device to improve melting efficiency. It solves the problems of large plastic pellets being difficult to melt quickly when introduced into the melting device, and plastic pellets accumulating in a fixed position, making it difficult for some plastic pellets to melt quickly.

[0005] The technical solution of this utility model is as follows: A recycled plastic granule melting device includes a cylinder, a cylinder cover is detachably installed on the top of the cylinder, a round sleeve is fixedly installed on the left side of the top of the cylinder cover, a feed pipe is fixedly installed on the left side of the round sleeve, a first motor is detachably installed on the top of the round sleeve, a round rod is detachably installed on the bottom output shaft of the first motor, a plurality of slices are fixedly installed on the outer surface of the round rod, and a scraper is fixedly installed on the other side of the slices.

[0006] Preferably, a second motor is detachably installed in the middle of the top of the cylinder cover, and a cylinder is detachably installed on the output shaft at the bottom of the second motor. Multiple stirring rods are fixedly installed on the outer surface of the cylinder. A control panel is detachably installed on the right side of the top of the cylinder cover, and wires are detachably installed on the outer surface of the control panel. An inclined plate is fixedly installed on the top of the inner cavity of the cylinder, and multiple round holes are opened on the surface of the inclined plate. Multiple heaters are detachably installed on the outer surface of the cylinder. A discharge pipe is fixedly installed at the bottom of the left side of the cylinder, and a valve is detachably installed in the inner cavity of the discharge pipe.

[0007] Preferably, the inner cavity of the round sleeve penetrates the bottom surface of the cylinder cover, and the round rod, the bottommost slice, and the bottommost scraper are located in the middle range of the cylinder cover. Thus, when in use, the range of the inner cavity of the round sleeve allows the plastic particles crushed inside the round sleeve to fall into the inner cavity of the cylinder.

[0008] Preferably, the right side of the feed pipe extends through into the inner cavity of the round sleeve, and the feed pipe and the round sleeve are connected at an angle. Thus, when in use, the plastic particles poured into the inner cavity of the feed pipe automatically roll into the inner cavity of the round sleeve due to the angled design of the feed pipe, and large pieces of plastic particles are quickly crushed by the rotating blades.

[0009] Preferably, the slices are evenly distributed on the outer surface of the portion of the round rod that extends into the inner cavity of the round sleeve, and the scraper is attached to the inner wall of the round sleeve. Both the front and rear sides of the slices and the scraper are designed with bevels. Both the slices and the scraper are made of alloy material. Thus, in use, by utilizing the material and shape of the slices and the scraper, the round rod is controlled to rotate when the first motor is started, which in turn drives the slices and the scraper to rotate. The rotating slices crush the plastic particles that have entered the inner cavity of the round sleeve, breaking the plastic particles into smaller volumes. At the same time, the scraper scrapes off any plastic particles that may adhere to the inner cavity of the round sleeve, avoiding waste caused by plastic particles adhering to the inner wall of the round sleeve.

[0010] Preferably, the stirring rods are evenly distributed on the outer surface of the portion of the cylinder extending into the inner cavity of the cylinder located at the bottom of the inclined plate. The outer surface of the stirring rods is designed with an inclined surface, so that when in use, the stirring rods can be used to fully mix the plastic particles in the inner cavity of the cylinder, which facilitates the melting of the plastic particles.

[0011] Preferably, the circular holes are evenly distributed on the outer surface of the inclined plate, and the inner diameter of the circular holes gradually increases from left to right. The left side of the inclined plate is higher than the right side. In use, by utilizing the inclined plate being directly below the circular sleeve and the inner diameter of the circular holes at different positions, the plastic particles falling through the circular sleeve pass through the inclined plate and the circular holes and automatically roll from left to right. When rolling, they automatically pass through different circular holes and fall into different positions in the inner cavity of the cylinder, avoiding the accumulation of plastic particles in a fixed position at the bottom of the inner cavity of the cylinder.

[0012] Preferably, the control panel is electrically connected to the first motor, the second motor, the heater, and the valve via wires, so that in use, different buttons on the surface of the control panel can be used to control the start and stop of the first motor, the second motor, the heater, and the valve respectively.

[0013] The working principle and beneficial effects of this utility model are as follows: This recycled plastic pellet melting device uses a combination of a round rod structure and a slicing structure. During operation, the material and shape of the slices and scrapers are used to control the rotation of the round rod when the first motor starts, which in turn drives the slices and scrapers to rotate. The rotating slices crush the plastic pellets that enter the inner cavity of the round sleeve into smaller volumes. At the same time, the scrapers scrape off any plastic pellets that may adhere to the inner cavity of the round sleeve, preventing plastic pellets from sticking to the inner wall of the round sleeve and causing waste. This achieves the effect of prioritizing the crushing of larger particles before melting, which facilitates rapid melting in the subsequent process.

[0014] This recycled plastic pellet melting device uses a combination of inclined plate and circular hole structures. During operation, the inclined plate is located directly below the circular sleeve, and the inner diameter of the circular holes at different positions allows the plastic pellets falling through the circular sleeve to automatically roll from left to right. As they roll, they automatically pass through different circular holes and fall into different positions within the inner cavity of the cylinder, preventing the plastic pellets from accumulating in a fixed position at the bottom of the inner cavity. This disperses the plastic pellets and improves the melting efficiency. Attached Figure Description

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

[0019] Please see Figures 1-5As shown, a recycled plastic granule melting device includes a cylinder 1. A cylinder cover 2 is detachably installed on the top of the cylinder 1. A circular sleeve 3 is fixedly installed on the left side of the top of the cylinder cover 2. A feed pipe 4 is fixedly installed on the left side of the circular sleeve 3. The right side of the feed pipe 4 extends through into the inner cavity of the circular sleeve 3. The feed pipe 4 and the circular sleeve 3 are connected at an angle, so that when in use, the plastic granules poured into the inner cavity of the feed pipe 4 automatically roll into the inner cavity of the circular sleeve 3 due to the inclined design of the feed pipe 4, and large pieces of plastic granules are quickly crushed by rotating slices 7. A first motor 5 is detachably installed on the top of the circular sleeve 3. A circular rod 6 is detachably installed on the bottom output shaft of the first motor 5. Multiple slices 7 are fixedly installed on the outer surface of the circular rod 6. A scraper 8 is fixedly installed on the other side of the slices 7. The slices 7 are evenly distributed. The outer surface of the portion of the round rod 6 that extends into the inner cavity of the round sleeve 3 is covered with a scraper 8. The scraper 8 is attached to the inner wall of the round sleeve 3. Both the front and rear sides of the scraper 7 and the scraper 8 are designed with bevels. Both the scraper 7 and the scraper 8 are made of alloy material. Thus, when in use, the material and shape of the scraper 7 and the scraper 8 are used to control the rotation of the round rod 6 when the first motor 5 is started, which in turn drives the scraper 7 and the scraper 8 to rotate. The rotating scraper 7 crushes the plastic particles that enter the inner cavity of the round sleeve 3, breaking the plastic particles into smaller volumes. At the same time, the scraper 8 scrapes off any plastic particles that may adhere to the inner cavity of the round sleeve 3, avoiding waste caused by plastic particles adhering to the inner wall of the round sleeve 3. The inner cavity of the round sleeve 3 extends through the bottom surface of the cylinder cover 2. The round rod 6, the bottom scraper 7, and the bottom scraper 8 are located on the cylinder cover. 2. Within the middle range, the plastic particles crushed inside the cylindrical sleeve 3 can fall into the inner cavity of the cylinder 1 during use. A second motor 9 is detachably installed in the middle of the top of the cylinder cover 2. A cylinder 10 is detachably installed on the output shaft at the bottom of the second motor 9. Multiple stirring rods 11 are fixedly installed on the outer surface of the cylinder 10. A control panel 12 is detachably installed on the right side of the top of the cylinder cover 2. A wire 13 is detachably installed on the outer surface of the control panel 12. An inclined plate 14 is fixedly installed at the top of the inner cavity of the cylinder 1. The stirring rods 11 are evenly distributed on the outer surface of the part of the cylinder 10 that extends into the inner cavity of the cylinder 1 and is located at the bottom of the inclined plate 14. The outer surface of the stirring rods 11 is all designed with a slope, so that the stirring rods 11 can fully mix and stir the cylinder 1 during use. The inner cavity contains plastic granules, facilitating their melting. Multiple circular holes 15 are evenly distributed on the outer surface of the inclined plate 14, with the inner diameter of each hole gradually increasing from left to right. The left side of the inclined plate 14 is higher than the right side. During use, the inclined plate 14, located directly below the circular sleeve 3, and the varying inner diameters of the holes 15 at different positions, cause the plastic granules falling through the circular sleeve 3 to automatically roll from left to right, passing through the inclined plate 14 and the holes 15. As they roll, they automatically pass through different holes 15 and fall into different positions within the inner cavity of the cylinder 1, preventing the plastic granules from accumulating at a fixed position at the bottom of the cylinder 1. Multiple heaters 16 are detachably installed on the outer surface of the cylinder 1, and a discharge pipe 17 is fixedly installed at the bottom left side of the cylinder 1.A valve 18 is detachably installed inside the discharge pipe 17. The control panel 12 is electrically connected to the first motor 5, the second motor 9, the heater 16, and the valve 18 via wires 13. Therefore, in use, different buttons on the surface of the control panel 12 are used to control the start and stop of the first motor 5, the second motor 9, the heater 16, and the valve 18 respectively.

[0020] Working principle: During operation, all structures are first correctly assembled. Then, the first motor 5, the second motor 9, and the heater 16 are started by controlling different buttons on the control panel 12. Next, the plastic granules to be melted are poured into the inner cavity of the feed pipe 4 and then into the inner cavity of the round sleeve 3. After being introduced into the inner cavity of the round sleeve 3, the first motor 5 is used to start and control the rotation of the round rod 6, the slice 7, and the scraper 8. With the shape of the slice 7 and the scraper 8, the plastic granules to be melted that have entered the inner cavity of the round sleeve 3 are quickly cut. The cut plastic granules fall into the inner cavity of the cylinder 1. At the same time, the scraper 8 scrapes off any plastic granules that may be adhering to the inner wall of the round sleeve 3 and they fall into the inner cavity of the cylinder 1. Next, the plastic particles falling into the inner cavity of the cylinder 1 fall directly onto the top surface of the inclined plate 14 due to its position. With the help of the circular holes 15 of different diameters on the surface of the inclined plate 14, the plastic particles on the surface of the inclined plate 14 roll down from left to right and disperse into the inner cavity of the cylinder 1. With the addition of the rotating cylinder 10 and the stirring rod 11, the plastic particles distributed in different positions in the inner cavity of the cylinder 1 are quickly mixed. At the same time, the heater 16 is activated to heat the inner cavity of the cylinder 1, thereby quickly melting the plastic particles. After a period of time, the first motor 5, the second motor 9 and the heater 16 are turned off by the buttons on the control panel 12. Then, the valve 18 is activated and opened to allow the melted plastic liquid in the inner cavity of the cylinder 1 to flow out of the inner cavity of the cylinder 1 through the discharge pipe 17. After all the plastic particles have flowed out, the above steps are repeated to melt the next batch of plastic particles.

[0021] In summary, compared with similar devices, this recycled plastic pellet melting device has the advantages of prioritizing the crushing of larger pellets before melting, facilitating rapid subsequent melting, and breaking down plastic pellets into smaller pieces before they enter the melting device, thereby improving melting efficiency.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
