Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a modified plastic extrusion device. Background Art

[0002] Existing modified plastic extruders are essential equipment specifically designed for processing modified plastics. They offer high efficiency, stability, and continuous production, making them widely used in the plastics processing industry. Through their unique screw design, heating system, and cooling system, modified plastic extruders melt, mix, plasticize, and extrude modified plastic raw materials, producing plastic products that meet specific requirements.

[0003] However, in actual production, modified plastic pellet raw materials often contain a certain amount of moisture. Failure to effectively remove this moisture can lead to a series of problems during extrusion, such as inadequate plastic melting, unstable extruded product quality, and increased equipment wear. Therefore, current production processes typically require a drying step before the extruder to pre-treat the raw materials and ensure their moisture content meets the extruder's requirements. However, this drying step not only complicates the production process but can also reduce production efficiency and increase costs. Furthermore, the drying equipment itself requires space and maintenance costs, which undoubtedly increases the operational burden on companies.

[0004] In order to solve the existing problems, the device proposes to add a drying mechanism inside the modified plastic extruder. Utility Model Content

[0005] In order to overcome the disadvantage that when the modified plastic extrusion equipment is in operation, the modified plastic granular raw materials often adhere to a certain amount of moisture, resulting in insufficient plastic melting or quality defects of the extruded plastic products, the utility model provides a modified plastic extrusion device with a drying function.

[0006] A modified plastic extrusion device includes an extruder, a conical feed bin is configured on the upper part of the extruder, a hot air blower, a support frame, a thermal bin and an air supply pipe. The hot air blower is fixed on the extruder, and the thermal bin is fixed to the upper part of the extruder through the support frame. The air outlet end of the hot air blower is connected to one side of the thermal bin, and the other side of the thermal bin is connected to the feed bin through the air supply pipe. The hot air blower is turned on to continuously heat the thermal bin, and the heat in the thermal bin is introduced into the feed bin through the air supply pipe to dry the modified plastic particles.

[0007] Furthermore, a heating plate is also included, and the heating plate is arranged in the thermal chamber.

[0008] Furthermore, it also includes a fixing frame, a rotating shaft and turbine blades. The fixing frame is fixed in the air supply pipe, and the turbine blades are rotatably connected in the fixing frame through the rotating shaft.

[0009] Furthermore, a filter screen is included, and the filter screen is located at the end of the air supply pipe.

[0010] Furthermore, the invention also comprises a heat-insulating pad, which is sleeved on the outside of the air supply pipe.

[0011] Furthermore, a bracket is also included, which is fixed to the outer wall of the feed bin and can support and fix the air supply pipe.

[0012] Furthermore, a protective pad is also included, and the protective pad cover is arranged outside the thermal chamber.

[0013] The beneficial effects of the present invention are as follows: the hot air blower is turned on to introduce heat into the thermal bin, which is then continuously guided into the feed bin by the air supply pipe. As the modified plastic particles in the feed bin are continuously stirred, the heat continuously output from the thermal bin can dry the modified plastic particle raw materials. Compared with the existing process that requires the modified plastic particle raw materials to be dried in advance, the present device can combine the drying and extrusion processes into one, thereby simplifying the production process and improving production efficiency.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: A modified plastic extrusion device, such as Figure 1 and Figure 2 As shown, it includes an extruder 1, a conical feed bin 2 is arranged on the upper part of the extruder 1, and the feed bin 2 uses a threaded rod for uniform feeding, and also includes a hot air blower 3, a support frame 4, a thermal bin 5 and an air supply pipe 7. The hot air blower 3 is fixed on the extruder 1, and the thermal bin 5 is fixed to the upper part of the extruder 1 through the support frame 4. The heating plate 6 is arranged in the thermal bin 5. The heating plate 6 can absorb the heat generated by the hot air blower 3 and then evenly conduct it through the air supply pipe 7. The air outlet end of the hot air blower 3 is connected to one side of the thermal bin 5, and the other side of the thermal bin 5 is connected to the feed bin 2 through the air supply pipe 7. The hot air blower 3 is turned on to continuously heat the thermal bin 5, and the heat in the thermal bin 5 is introduced into the feed bin 2 through the air supply pipe 7 to dry the modified plastic particles.

[0021] like Figure 3 As shown, it also includes a fixed frame 8, a rotating shaft 9 and a turbine blade 10. The fixed frame 8 is fixedly connected to the air supply pipe 7, and the turbine blade 10 is rotatably connected to the fixed frame 8 through the rotating shaft 9. After the hot air blower 3 is turned on, heat is continuously introduced from the thermal bin 5 into the silo 2. The fast-moving air will drive the turbine blade 10 to rotate. At the same time, the turbine blade 10 can also accelerate the introduction of hot air, so that the heat in the thermal bin 5 is continuously guided into the silo 2 in large quantities.

[0022] like Figure 4 As shown, a filter screen 11 is also included. The filter screen 11 is located at the end of the air supply pipe 7. The filter screen 11 can effectively prevent impurities such as dust in the air from invading the silo 2.

[0023] like Figure 4 As shown, a heat preservation pad 12 is also included. The heat preservation pad 12 is sleeved on the outside of the air supply pipe 7. The heat preservation pad 12 reduces the heat loss of the air supply pipe 7 and improves the subsequent drying efficiency of the modified plastic particle raw material.

[0024] like Figure 4 As shown, a bracket 13 is also included. The bracket 13 is fixed to the outer wall of the feed bin 2. The bracket 13 can support and fix the air supply pipe 7.

[0025] like Figure 4 As shown, a protective pad 14 is also included, and the protective pad 14 is covered on the outside of the thermal chamber 5.

[0026] Working principle: The modified plastic granule raw material is introduced into the feed hopper 2. The feed hopper 2 uses a threaded rod for uniform feeding. Therefore, the modified plastic granules in the feed hopper 2 can be fully stirred when entering the extruder 1. The hot air blower 3 is turned on to heat the thermal chamber 5. A heating plate 6 is provided in the thermal chamber 5. The heating plate 6 can absorb the heat generated by the hot air blower 3 and then evenly discharge it through the air supply pipe 7. Therefore, after the hot air blower 3 is turned on, a large amount of heat will be evenly introduced into the feed hopper 2 through the air supply pipe 7. In order to prevent dust and other impurities from entering the feed hopper 2, a filter 11 is provided to filter the air. As the modified plastic granules in the feed hopper 2 continue to be stirred, the heat continuously output from the thermal chamber 5 can dry the modified plastic granule raw material. Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims should be given the broadest interpretation to cover all variations and equivalent structures and functions.
