Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a raw material melting device for plastic film. Background Technology

[0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging and as a coating layer. In the processing and production of plastic films, different types of raw materials first need to be melted using a melting device to facilitate subsequent molding and processing of the melted materials.

[0003] Patent document CN220428938U discloses a raw material melting device for plastic film production, belonging to the field of plastic film production technology. It includes a base with an insulated shell installed on the top of the base. This utility model can melt the plastic film raw material put into the inner tank by setting the heating component. With the setting of the anti-clogging filter component, the device has a reasonable structure and can filter the molten particle residue during plastic film production and has the function of preventing clogging.

[0004] The plastic film raw material melting devices proposed in the above patent documents, in actual use, only use an electric heating plate on the inner wall of the outer shell to heat the raw material, which cannot fully heat the raw material in different positions inside the device. This results in uneven heating of the raw material inside the device, affecting the mixing and heating effect of the raw material. To address this, we have designed a plastic film raw material melting device. Utility Model Content

[0007] The heating assembly includes an annular heating sleeve fixedly connected between the inner bottom wall and the inner top wall of the mixing tank. Several electric heating tubes are fixedly arranged between the outer side of the annular heating sleeve and the inner wall of the mixing tank.

[0010] In a preferred embodiment, the input end of the circulating water pump is fixedly connected to a connecting conduit, and the end of the connecting conduit away from the circulating water pump extends into the interior of the first strip-shaped shell.

[0011] In a preferred embodiment, the two ends of the guide tube extend into the interior of the drive tube and the movable stirring tube, respectively, and the interiors of the drive tube, the guide tube, and the movable stirring tube are interconnected.

[0012] In a preferred embodiment, a plurality of metal filters are fixedly connected to the inner side of the movable stirring tube, and the plurality of metal filters and guide tubes are evenly and alternately distributed between the drive tube and the movable stirring tube.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1 and Figure 2A raw material melting device for plastic film includes a mixing tank 1. The mixing tank 1 is equipped with a heating component 2 and a mixing component 3. By setting the heating component 2 and the mixing component 3, the heating component 2 can heat the raw material, and the mixing component 3 can mix the raw material in the mixing tank 1.

A plurality of electric heating tubes 202 are fixedly disposed between the outer side of the annular heating sleeve 201 and the inner wall of the mixing tank 1. A first strip shell 4 and a second strip shell 5 are fixedly disposed on the left and right sides of the mixing tank 1, respectively. The first strip shell 4 and the second strip shell 5 are both embedded in the interior of the mixing tank 1, and the first strip shell 4 and the second strip shell 5 are both connected to the interior of the annular heating sleeve 201.

[0031] It should be noted that a water inlet pipe 17 is fixedly installed on the upper surface of the first strip shell 4, an electronic level gauge 18 is fixedly installed on the inner wall of the second strip shell 5, and a control panel 9 is fixedly installed on the side of the second strip shell 5. The control panel 9 is electrically connected to the electronic level gauge 18, the drive motor 19, the electric heating tube 202 and the circulating water pump 6 respectively.

[0032] Reference Figure 3 In a preferred embodiment, the mixing assembly 3 includes a drive pipe 301 rotatably connected to the bottom wall of the mixing tank 1. Two movable stirring pipes 302 are fixedly disposed on the surface of the drive pipe 301, and a plurality of guide pipes 303 are fixedly disposed between the movable stirring pipes 302 and the drive pipe 301.

[0033] A drive box 11 is fixedly installed on the upper surface of the mixing tank 1. A driven synchronous wheel 12 is fixedly installed on the top of the drive tube 301. A drive motor 19 is fixedly installed on the inner wall of the drive box 11. A drive synchronous wheel 13 is fixedly connected to the rotating shaft of the drive motor 19. A transmission belt 14 is installed between the drive synchronous wheel 13 and the driven synchronous wheel 12. By setting the drive synchronous wheel 13 and the driven synchronous wheel 12, the drive motor 19 can drive the drive tube 301 to rotate, thereby driving the mixing component 3 to stir and mix the raw materials in the mixing tank 1.

[0034] It should be noted that the two ends of the guide tube 303 extend into the interior of the drive tube 301 and the movable stirring tube 302, respectively, and the interiors of the drive tube 301, the guide tube 303 and the movable stirring tube 302 are interconnected.

[0035] It should be further explained that a number of metal filters 304 are fixedly connected to the inner side of the movable stirring tube 302, and the metal filters 304 and the guide tube 303 are evenly and alternately distributed between the drive tube 301 and the movable stirring tube 302.

[0036] It is worth noting that by setting a metal filter screen 304 between the movable stirring tube 302 and the guide tube 303, the metal filter screen 304 can be driven to rotate in the mixing tank 1 during the rotation of the movable stirring tube 302. This allows the metal filter screen 304 to screen the lumps in the raw materials and make the raw material particles finer, thus facilitating the mixing and melting of raw materials of different particle sizes.

[0037] Reference Figure 3 and Figure 5 In a preferred embodiment, the output end of the circulating water pump 6 is fixedly connected to a first water delivery pipe 7, the end of the first water delivery pipe 7 away from the circulating water pump 6 extends into the interior of the mixing tank 1, and the input end of the circulating water pump 6 is fixedly connected to a connecting conduit 10, the end of the connecting conduit 10 away from the circulating water pump 6 extends into the interior of the first strip shell 4.

[0038] It should be noted that the bottom end of the drive pipe 301 extends to the outside of the mixing tank 1 and is rotatably connected to the output end of the first water delivery pipe 7. The top end of the drive pipe 301 extends to the outside of the mixing tank 1 and is rotatably connected to the second water delivery pipe 8. The end of the second water delivery pipe 8 away from the drive pipe 301 extends into the interior of the second strip shell 5. The circulating water pump 6 can circulate the hot water inside the annular heating jacket 201 with the hot water inside the drive pipe 301, thereby forming a circulating flow of hot water inside the mixing tank 1 and improving the heating effect on the raw materials.

[0039] It is worth noting that by installing a heating component 2 and a mixing component 3 inside the mixing tank 1, the water between the annular heating sleeve 201 and the mixing tank 1 can be heated by the electric heating tube 202, thereby heating the raw materials by the annular heating sleeve 201. Furthermore, the hot water in the annular heating sleeve 201 can be input into the drive pipe 301 through the first conveying water pipe 7 by the circulating water pump 6, and then the hot water can be transported to the two movable stirring tubes 302 and several guide pipes 303 by the drive pipe 301. Thus, the raw materials in different positions inside the mixing tank 1 can be heated evenly during the stirring of the raw materials by the movable stirring tubes 302, resulting in more thorough heating of the raw materials and improving the heating efficiency of the raw materials.

[0040] Working principle: In operation, the raw materials for producing plastic film are first fed into the mixing tank 1 through the feed pipe 15, and water is added to the inside of the first strip shell 4 through the water inlet pipe 17. The water enters the annular heating jacket 201 and the second strip shell 5 from the first strip shell 4. Then, the water is heated by the electric heating tube 202, and the hot water is used to heat the annular heating jacket 201. The annular heating jacket 201 is used to heat the raw materials in the mixing tank 1. At the same time, the drive motor 19 drives the drive synchronous wheel 13 to rotate, which in turn drives the driven synchronous wheel 12 and the drive synchronous wheel 13. When pipe 301 rotates, the drive pipe 301 drives the movable stirring pipe 302 to rotate, and the movable stirring pipe 302 drives several guide pipes 303 to rotate, thereby stirring and mixing the raw materials. At the same time, the circulating water pump 6 uses the hot water inside the annular heating jacket 201 to be input into the drive pipe 301 through the first conveying water pipe 7, and the drive pipe 301 uses the hot water to be transported to several guide pipes 303 and the movable stirring pipe 302, thereby heating the raw materials at different positions in the mixing tank 1, making the raw materials more evenly heated, and thus improving the melting effect of the raw materials.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
