Description

Technical Field

[0001] This utility model relates to the field of resin melt processing, and more specifically, to a polymodified ethylene resin melt processing device. Background Technology

[0002] Resin melting refers to the physical process by which solid resin materials (usually thermoplastic resins or uncured thermosetting resins) absorb heat under heating conditions, intensify molecular chain movement, overcome intermolecular forces, and transform from an ordered solid state (crystalline or glassy state) into a disordered, flowable viscous liquid state (melt). Among them, polymodified ethylene resin melting refers to the process by which materials formed after physical or chemical modification of polyethylene (PE) resin transform from a solid state to a flowable molten state under heating conditions.

[0003] In existing technologies, when melting polymodified ethylene resin, a melting device with heating and stirring functions is used to stir the material, and then the material is extruded using a screw. However, after stirring, the existing melting device often results in uneven heating due to the single stirring position, and residual material will stick to the inner wall of the melting chamber after processing. Due to space constraints, cleaning is also more difficult, reducing the overall practicality of the melting device. Utility Model Content

Secondly, it can also utilize a retractable cleaning tube set inside the stirring roller to achieve rapid cleaning in the empty state of the hot melt tank, thus improving the practicality and ease of use of the device.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A polymodified ethylene resin melting device includes a can lid adapted to a hot melt tank, a motor fixedly mounted on the surface of the can lid, and a pulley fixedly sleeved on the output shaft of the motor. It also includes...

[0017] 3. Beneficial Effects

[0030] Example:

[0031] Please see Figure 1-4 A polymodified ethylene resin melting device includes a can lid 2 adapted to a hot melt tank 1, a motor 3 fixedly mounted on the surface of the can lid 2, and a pulley 4 fixedly sleeved on the output shaft of the motor 3. The device also includes...

[0032] A rotating shaft 5 is installed inside the hot melt tank 1. An installation cone 6 is fixedly installed at the bottom end of the rotating shaft 5. Several stirring rollers 7 are fixedly installed on the outer wall of the installation cone 6. The top of the rotating shaft 5 is connected to each other through a belt and a pulley 4. A connecting pipe 11 is fixedly installed inside the rotating shaft 5. Several infusion pipes 12 are fixedly connected to the surface of the connecting pipe 11.

[0033] The cleaning device 8 includes a synchronization ring 801 fixedly installed on the surface of the rotating shaft 5, and a plurality of connecting rods 802 are fixedly installed on the outer wall of the synchronization ring 801.

[0034] It should be noted that the discharge valve 9 and the motor 3 in this application are both existing mature technologies, so the specific internal structure of the two will not be described in detail.

[0035] An accumulation platform 101 is integrally formed at the bottom of the hot melt tank 1. A discharge valve 9 is fixedly connected to the bottom of the hot melt tank 1. An inclined bar 803 is fixedly connected to the outer end of the connecting rod 802. A scraper 804 is fixedly installed at the bottom end of the inclined bar 803. The bottom surface of the scraper 804 is attached to the top surface of the accumulation platform 101. The outer surface of the inclined bar 803 is attached to the inner wall of the hot melt tank 1.

[0036] Specifically, the inclined structure of the accumulation platform 101 allows the wastewater during cleaning and the material during melting to fall towards the center under the influence of gravity. Then, the inclined setting of the scraper 804 and the inclined bar 803 can generate a centripetal force, which accelerates the speed of fluid falling while rotating, thus improving the overall practicality of the device. Furthermore, the connecting rod 802 can stir the area above the mounting cone 6, expanding the stirring area. Finally, the threaded progression of the screw rod 602 can ensure that the material is discharged evenly.

[0037] The top of the tank cover 2 is fixedly connected to the feed valve 201. The top of the tank cover 2 is also fixedly connected to the pump body 10. One end of the pump body 10 is connected to the water pipe and the connecting pipe 11. The bottom end of the mounting cone 6 is fixedly connected to the connecting column 601. The bottom end of the connecting column 601 is fixedly connected to the spiral rod 602. The spiral rod 602 is rotatably installed inside the discharge valve 9. The inside of the stirring roller 7 is fixedly connected to the winding and distributed resistance coil 701. The middle of the stirring roller 7 is movably sleeved with the spray pipe 13. The outer wall of the spray pipe 13 is fixedly installed with the magnetic ring 14. The inside of the stirring roller 7 is fixedly installed with the electromagnetic plate 17 that is magnetically attracted to the magnetic ring 14. The spray pipe 13 and the infusion pipe 12 are connected to each other. The outer end of the spray pipe 13 is integrally formed with a spray head 15. The surface of the spray head 15 is provided with spray holes 16.

[0038] Specifically, the winding installation of the resistor coil 701 ensures uniform heating of the stirring roller 7, guaranteeing heat transfer during stirring. Secondly, the electromagnetic plate 17 ensures stable connection between the magnetic ring 14 and the stirring roller 7 when energized, preventing dislocation. When de-energized, the magnetic force between them disappears, and the magnetic ring 14 is thrown out by centrifugal force as the stirring roller 7 revolves, causing the spray head 15 and spray hole 16 to extend from the inside of the stirring roller 7. As the stirring roller 7 rotates, the cleaning liquid is sprayed onto the inner wall of the hot melt tank 1. It should be noted that the starting of the resistor coil 701 and the electromagnetic plate 17 in this application is an electrically controlled start. This starting method is prior art and can be accomplished by existing controllers and other existing components. Therefore, this application will not elaborate on this prior art.

[0039] The working principle of this utility model is as follows: First, the material enters the interior of the hot melt tank 1 through the feed valve 201. Then, the resistance coil 701 is activated to heat the stirring roller 7. Next, the motor 3 is started to drive the pulley 4 to rotate, which in turn causes the rotating shaft 5 to rotate. The rotating shaft 5 drives all the stirring rollers 7 to rotate through the mounting cone 6, thus hot-melting and stirring the material. At this time, the rotating shaft 5 also drives the synchronous ring 801 to rotate, the connecting rod 802 to stir, and the inclined bar 803 and scraper 804 scrape and rotate along the inner wall of the hot melt tank 1 and the top surface of the accumulation platform 101, respectively. Finally, the material passes through the... The material enters the surface of the screw rod 602 through the middle of the accumulation platform 101 and exits through the discharge valve 9. When the inside of the hot melt tank 1 needs to be cleaned, the electromagnetic plate 17 is de-energized, and the magnetic ring 14 loses its magnetic force. The stirring roller 7 continues to rotate with the rotation of the mounting cone 6. The magnetic ring 14 and the spray pipe 13 have centrifugal force. The spray head 15 and the spray hole 16 are thrown out of the end of the stirring roller 7. Then the cleaning liquid is introduced into the inside of the connecting pipe 11 through the pump body 10, and finally enters the inside of the spray pipe 13 from the inside of the delivery pipe 12. It is then sprayed out from the spray hole 16 and acts on the inside of the hot melt tank 1.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
