Description

Technical Field

[0001] This utility model belongs to the field of plastic materials technology, and relates to plastic modified materials, particularly a melting device for plastic modified materials. Background Technology

[0002] Modified plastic materials refer to plastics whose properties are altered by adding different modifiers to achieve specific uses and improve their physical and chemical properties. Modification can improve the strength, toughness, temperature resistance, corrosion resistance, flame retardancy, etc., of plastics, thus enabling them to play a role in a wider range of fields. In order to make the plastic material flowable, so as to facilitate processing through molds or molding equipment, and to ensure that the modifier is evenly dispersed in the substrate, a melting device is needed to melt the modified plastic material. However, most of the melting devices for modified plastic materials in the current technology still have problems that need to be solved.

[0003] In most existing plastic modification material melting devices, a stirrer is used to agitate the material during melting to prevent material accumulation. However, the agitation effect of most existing plastic modification material melting devices is not ideal. The material is driven along the movement direction and rotation path of the stirrer blades, moving along the flow path of the blades. Moreover, since plastic modification materials are relatively viscous, moving along the stirrer may create dead zones or areas with insufficient movement, resulting in the material not being able to disperse in different areas. The material in different areas may be heated unevenly and cannot be fully mixed with the modifier. Therefore, it is urgent to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a melting device for plastic modified materials. The technical problem this invention aims to solve is: how to fully stir the plastic modified materials to ensure uniform mixing with the modifier and uniform heating.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A melting device for modified plastic materials includes an insulated tank with an inner tank body fixedly connected to it. A lid is located on the top of the inner tank body. A first rotating shaft is located at the bottom of the lid, and a second rotating shaft is fitted onto the first rotating shaft. The second rotating shaft is slidably connected to the first rotating shaft. Two fixed shafts are fixedly connected to the outer wall of the bottom end of the second rotating shaft, and rollers are fitted onto each of the two fixed shafts. The rollers are rotatably connected to the fixed shafts. A fixing member is fixedly connected to the outer wall of the bottom end of the second rotating shaft, and a stirring shaft is fixedly connected to the bottom of the fixing member. Several stirrers are fixedly connected to the stirring shaft. A circular tube is located at the bottom of the lid, and a symmetrical groove is formed inside the circular tube. The rollers are disposed within the groove.

[0007] The working principle of this invention is as follows: Material is placed into the inner tank, and the lid is closed. When the first rotating shaft rotates, it drives the second rotating shaft to rotate. The second rotating shaft drives the fixing component to rotate, which in turn drives the stirring shaft to rotate. The stirring shaft then drives the agitator to rotate, stirring the material inside the inner tank and promoting uniform mixing of the modifier and the base material. The rotation of the second rotating shaft also drives the fixing shaft to perform a circular motion, causing the rollers to move within the chute. When the rollers rise along the chute, the fixing shaft rises, which in turn drives the second rotating shaft to rise. The second rotating shaft then drives the fixing component to rise, which in turn drives the stirring shaft to rise. The stirring shaft then drives the agitator to rise. When the rollers descend along the chute, the agitator also descends. Therefore, the second rotating shaft can repeatedly rise and fall during rotation, and the agitator can also repeatedly rise and fall during rotation, ensuring that the material inside the inner tank is fully stirred and preventing the material from moving along the agitator's path and creating a stirring dead zone.

[0008] The bottom of the can lid is fixedly connected to an annular plate, the bottom of the annular plate is fixedly connected to a base plate, and the top of the base plate is fixedly connected to the bottom of the circular tube.

[0009] A temperature sensor is fixedly connected to the bottom of the base plate.

[0010] Using the above structure, the temperature inside the inner tank is detected by a temperature sensor.

[0011] Several heaters are fixedly connected to the outer wall of the inner tank, and the heaters are arranged between the heat preservation tank and the inner tank.

[0012] Using the above structure, the inner tank is heated by a heater, which allows the base material and modifier inside the inner tank to be fully melted and mixed.

[0013] The bottom of the heat preservation tank is fixedly connected to a base, and the heat preservation tank and the inner tank are fixedly connected to the same discharge pipe, and a valve is installed on the discharge pipe.

[0014] With the above structure, the molten material in the inner tank can be discharged by opening the valve on the discharge pipe.

[0015] A temperature controller is fixedly connected to the outer wall of the insulated tank, and the temperature controller is electrically connected to the heater and the temperature sensor via a guide.

[0016] A fixing frame is fixedly connected to the top of the can lid, and a motor is fixedly connected to the top of the fixing frame. A bearing is installed on the can lid, and the outer wall of the outer ring of the bearing is fixedly connected to the can lid. A drive shaft is fixedly connected to the inner wall of the inner ring of the bearing. The drive shaft is fixedly connected to a first rotating shaft. The motor and the drive shaft are connected by a coupling. Two lifting rings are fixedly connected to the top of the can lid.

[0017] With the above structure, the lifting rope can be tied to the lifting ring, and the can lid can be lifted using lifting equipment.

[0018] Compared with the prior art, the melting device for plastic modified materials of this utility model has the following advantages:

[0019] In this invention, by employing a technique that allows the stirrer to rotate while simultaneously moving up and down, the stirrer's vertical movement ensures contact with materials at various heights within the inner tank. This allows for thorough mixing of the materials, reducing dead zones and ensuring uniform heating and complete mixing with the modifier. This effectively solves the problem mentioned in the prior art where existing plastic modifiers often suffer from unsatisfactory stirring effects with melting devices. Materials are often driven along the direction and path of the stirrer blades, moving along their flow path. Furthermore, the viscous nature of plastic modifiers can lead to dead zones or insufficient movement along the stirrer, resulting in uneven heating and incomplete mixing with the modifier. This invention achieves the technical effect of allowing the stirrer to reach all heights within the inner tank, reducing dead zones and omissions, ensuring more comprehensive stirring, and guaranteeing uniform heating and thorough mixing of materials in different areas with the modifier.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figure 1 - Figure 7As shown, a melting device for plastic modified materials includes a heat-insulating tank 1, an inner tank 2 inside the heat-insulating tank 1, the inner tank 2 being fixedly connected to the heat-insulating tank 1, a tank cover 3 on the top of the inner tank 2, a first rotating shaft 5 at the bottom of the tank cover 3, a second rotating shaft 6 sleeved on the first rotating shaft 5, the second rotating shaft 6 being slidably connected to the first rotating shaft 5, two fixed shafts 7 fixedly connected to the bottom outer wall of the second rotating shaft 6, each fixed shaft 7 being fitted with a roller 8, the roller 8 being rotatably connected to the fixed shaft 7, a fixing member 9 fixedly connected to the bottom outer wall of the second rotating shaft 6, a stirring shaft 10 fixedly connected to the bottom of the fixing member 9, a plurality of stirrers 11 fixedly connected to the stirring shaft 10, a circular tube 12 at the bottom of the tank cover 3, a symmetrical groove 13 being formed inside the circular tube 12, the rollers 8 being disposed in the groove 13, an annular plate 14 fixedly connected to the bottom of the tank cover 3, a base plate 15 fixedly connected to the bottom of the annular plate 14, the base plate 15... The top of the inner tank 1 is fixedly connected to the bottom of the round tube 12. The bottom of the base plate 15 is fixedly connected to the temperature sensor 16. Several heaters 17 are fixedly connected to the outer wall of the inner tank 2. The heaters 17 are located between the heat preservation tank 1 and the inner tank 2. The bottom of the heat preservation tank 1 is fixedly connected to the base 18. The heat preservation tank 1 and the inner tank 2 are fixedly connected to the same discharge pipe 19. A valve is installed on the discharge pipe 19. A temperature controller 23 is fixedly connected to the outer wall of the heat preservation tank 1. The temperature controller 23 is electrically connected to the heaters 17 and the temperature sensor 16 through a guide. The top of the lid 3 is fixedly connected to the fixing frame 20. The top of the fixing frame 20 is fixedly connected to the motor 24. A bearing 21 is installed on the lid 3. The outer ring of the bearing 21 is fixedly connected to the lid 3. The inner ring of the bearing 21 is fixedly connected to the drive shaft 4. The drive shaft 4 is fixedly connected to the first rotating shaft 5. The motor 24 and the drive shaft 4 are connected by a coupling. The top of the lid 3 is fixedly connected to two lifting rings 22.

[0030] The working principle of this utility model is as follows: In use, materials are placed into the inner tank 2, the lid 3 is closed, and an external power supply is connected. The heater 17 is started, heating the inner tank 2 and raising its internal temperature. This heats and melts the modified plastic material inside the inner tank 2. The temperature sensor 16 detects the temperature inside the inner tank 2 and feeds the data back to the temperature controller 23. The temperature controller 23 adjusts the power of the heater 17 according to a preset value: when the temperature inside the inner tank 2 is below the preset value, it increases the power of the heater 17; when it is above the preset value, it decreases the power. Then, the motor 24 is started. The output of the motor 24 drives the coupling to rotate, which in turn drives the drive shaft 4 to rotate. The drive shaft 4 drives the first rotating shaft 5 to rotate, which in turn drives the second rotating shaft 6 to rotate. The second rotating shaft 6 drives the fixing member 9 to rotate, which in turn drives the stirring shaft 10 to rotate. The stirring shaft 10 then drives the agitator 11 to rotate, stirring the material inside the inner tank 2 and promoting the modification of the material. The agent and the base material are uniformly mixed. When the second rotating shaft 6 rotates, it also drives the fixed shaft 7 to make a circular motion. The fixed shaft 7 drives the roller 8 to move in the slide 13. When the roller 8 rises along the slide 13, it can make the fixed shaft 7 rise. The rise of the fixed shaft 7 will drive the second rotating shaft 6 to rise. The second rotating shaft 6 will drive the fixing part 9 to rise. The fixing part 9 will drive the stirring shaft 10 to rise. The stirring shaft 10 will drive the agitator 11 to rise. When the roller 8 falls along the slide 13, the agitator 11 will also fall. Therefore, the second rotating shaft 6 can rise and fall back and forth when it rotates. The agitator 11 can also rise and fall back and forth during the rotation process, so that the material in the inner tank 2 can be fully stirred. It can prevent the material from moving along the moving path of the agitator 11 and creating a stirring dead zone. Stirring can also make the material heat up evenly, so that the material in the inner layer of the inner tank 2 has a lower heating efficiency than the material in the outer layer. After the melting work is completed, the valve of the discharge pipe 19 is opened to discharge the melted material.

[0031] In summary, in this invention, the up-and-down movement of the stirrer allows it to reach all height areas within the inner tank, reducing dead zones and omissions, enabling the material to be more thoroughly stirred, and ensuring that the material in different areas is uniformly heated and fully mixed with the modifier.
