Abstract
Description
Technical Field
[0001] This utility model relates to the field of modified plastics production technology, and in particular to a melting device for modified plastics production. Background Technology
[0002] Melting equipment for modified plastics production is used to heat, melt, and process plastic granules. It is mainly used in the plastic modification process to mix different kinds of additives with base plastics to achieve the desired physical and chemical properties. Common melting equipment includes single-screw extruders. The working principle is to heat and melt the plastic by rotating the screw and push it to form in the mold. The single-screw extruder has a screw inside that is responsible for conveying the plastic granules to the heating area and melting them, so that the materials are heated and mixed. The barrel is a long cylindrical pipe in which the screw rotates.
[0003] Plastic granules are fed into the barrel through the feeding hopper. Due to the large quantity of plastic granules, they may stick together. This sticking can cause blockages in the feeding hopper, preventing them from being evenly distributed during the melting process. This results in uneven material distribution and affects the quality of the final product. Therefore, it is particularly important to design a melting device for the production of modified plastics. Utility Model Content
[0004] The purpose of this invention is to provide a melting device for the production of modified plastics, in order to solve the problem mentioned in the background art that particle adhesion will cause blockage in the feeding hopper, making it impossible to distribute evenly during the melting process, resulting in uneven material distribution and affecting the quality of the final product.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a melting device for producing modified plastics, comprising a barrel, a drive motor, a heating cylinder, and an extrusion tube. The drive motor is located on one side of the barrel, the heating cylinder is located on the other side of the barrel, and the extrusion tube is located on one side of the heating cylinder. A feed pipe is inserted and connected to the top of the barrel. Two L-shaped frames are provided on the top of the barrel. An auxiliary sleeve is fitted at one end of the feed pipe. A discharge hole is opened on the surface of the auxiliary sleeve. A corrugated pipe is provided inside the discharge hole. A feeding hopper is provided at one end of the corrugated pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model is equipped with an auxiliary sleeve, a corrugated pipe, a feeding hopper, a vibrating motor, a circular sleeve, and a spring. Plastic granules and additives are sequentially fed into the inside of the feeding pipe through the feeding hopper for heating treatment. At this time, the vibrating motor is started, which drives the feeding hopper connected to its eccentric shaft to vibrate. The L-shaped frame and the circular sleeve are connected by a spring. As the feeding hopper shakes, the plastic granules and additives can also shake, avoiding the adhesion and accumulation between plastic granules.

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.
[0021] Please see Figure 1-4 This utility model provides a technical solution for a melting device for the production of modified plastics:
[0022] Example 1:
[0023] like Figure 1-3 As shown, a melting device for producing modified plastics includes a barrel 1, a drive motor 2, a heating cylinder 3, and an extrusion tube 4. The drive motor 2 is located on one side of the barrel 1, the heating cylinder 3 is located on the other side of the barrel 1, and the extrusion tube 4 is located on one side of the heating cylinder 3. A feed pipe 5 is inserted and connected to the top of the barrel 1. Two L-shaped frames 7 are provided on the top of the barrel 1. An auxiliary sleeve 6 is fitted onto one end of the feed pipe 5. A discharge hole 15 is opened on the surface of the auxiliary sleeve 6. A corrugated pipe 8 is provided inside the discharge hole 15. A feeding hopper 9 is provided at one end of the corrugated pipe 8. A contact cover 17 is provided on the top of the feeding hopper 9. A limit cover 14 is provided inside the contact cover 17. A vibration motor 10 is installed on one side. The L-shaped frame 7 and the round sleeve 11 are connected by a spring 12. The round sleeve 11 is fixedly fitted at one end of the feeding hopper 9. Springs 12 are installed on the top of both L-shaped frames 7. Plastic granules and additives are fed into the inside of the feeding pipe 5 through the feeding hopper 9 for heating treatment. At this time, the vibration motor 10 is started, which drives the feeding hopper 9 connected to its eccentric shaft to vibrate. The L-shaped frame 7 and the round sleeve 11 are connected by a spring 12. As the feeding hopper 9 shakes, the plastic granules and additives can also shake, avoiding the adhesion and accumulation between plastic granules. Vibration helps to break up the layering and make the material mix and melt more evenly.
[0024] Example 2:
[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, one end of each of the two springs 12 is fixedly connected to the bottom of the circular sleeve 11. The positions of the two limiting blocks 13 are corresponding. Limiting blocks 13 are fixedly installed on both sides of the limiting cover 14. A wear-resistant layer 16 is provided on the inner surface of the limiting cover 14. The auxiliary sleeve 6 is fixedly sleeved on one end of the feed pipe 5. The other end of the corrugated pipe 8 is inserted and connected to the inside of the discharge hole 15. A heating tube is provided inside the heating cylinder 3. One side of each of the two L-shaped brackets 7 is fixedly connected to both sides of the auxiliary sleeve 6. The limiting block 13, the limiting cover 14, the wear-resistant layer 16, and the contact cover 17 are provided. One side of the two limiting blocks 13 is fixed to the two sides of the contact cover 17 respectively. The wear-resistant layer 16 is made of alumina, which has high hardness, heat resistance and chemical stability, and can resist wear, thus extending the service life of the feeding hopper 9. Since the corrugated pipe 8 is composed of foldable corrugated sheets, the vibration of the feeding hopper 9 will cause the corrugated pipe 8 to shake, thus preventing plastic particles from clogging inside the corrugated pipe 8.
[0026] Working Principle: The melting device for modified plastics production is used to heat, melt, and process plastic granules. It is mainly used in the plastic modification process to mix different types of additives with the base plastic to achieve the desired physical and chemical properties. Common melting devices include single-screw extruders. The working principle involves heating and melting the plastic through the rotation of the screw, which then pushes it into the mold. The single-screw extruder contains a screw that transports the plastic granules to the heating zone and melts them, heating and mixing the materials. The barrel 1 is a long cylindrical pipe in which the screw rotates. Plastic granules are fed into the barrel 1 through the feeding hopper 9. Due to the large quantity of plastic granules, adhesion may occur, forming blockages in the feeding hopper 9. This prevents even distribution during the melting process, resulting in uneven material distribution and affecting the quality of the final product. Therefore, designing a melting device for modified plastics production is crucial. Plastic granules and additives are sequentially fed into the feed pipe 5 through the feeding hopper 9. During the heating process, the vibration motor 10 is started, driving the feeding hopper 9 connected to its eccentric shaft to vibrate. The L-shaped frame 7 and the round sleeve 11 are connected by a spring 12. As the feeding hopper 9 shakes, the plastic particles and additives also shake, preventing the plastic particles from sticking together and accumulating. Vibration helps to break up the stratification, making the material mix and melt more evenly. The heating cylinder 3 is equipped with a heating tube. As the heating tube is started, the material transported inside is heated and melted. The additives are also injected into the heating cylinder 3. The mixing of the additives and the material completes the plastic modification. One side of the two limiting blocks 13 is fixed to the two sides of the contact cover 17 respectively. The wear-resistant layer 16 is made of alumina, which has high hardness, heat resistance and chemical stability, and can resist wear, thus extending the service life of the feeding hopper 9. Since the corrugated pipe 8 is composed of foldable corrugated sheets, the vibration of the feeding hopper 9 also drives the corrugated pipe 8 to shake, preventing plastic particles from clogging inside the corrugated pipe 8.
