Description

Technical Field

[0001] This utility model relates to the technical field of plastic processing, and in particular to a melt extrusion device for reinforced modified polypropylene plastic granules. Background Technology

[0002] Polypropylene plastic has advantages such as low density, corrosion resistance, and good insulation, and is widely used in many fields such as automobiles, home appliances, and packaging.

[0003] To further improve the mechanical properties of polypropylene (PP) plastics and expand their application range, PP plastics typically require reinforcement modification treatment. This is achieved by adding reinforcing agents such as glass fiber and carbon fiber to the PP raw material, followed by melt mixing and extrusion molding. However, because toughening agents and lubricants are added to the surface of modified PP granules (PP raw material), clumping may occur if improper storage conditions (such as elevated temperature) are encountered during storage. Existing melt extrusion equipment processes the raw material directly after feeding, and the melting time of clumped raw material is longer than that of unclumped raw material. This affects the plastic extrusion process and may lead to a decrease in the quality of the produced plastic. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one objective of this invention is to provide a melt extrusion device for reinforced modified polypropylene plastic granules, which can break up the raw materials during the feeding process to ensure the consistency of the raw material particle size during feeding and to ensure the quality of the plastic after melt extrusion.

[0006] To achieve the above objectives, this utility model proposes an extruder, an integrated component, and a dispersing mechanism for a melt extrusion device for reinforced modified polypropylene plastic granules. The integrated component is mounted on the extruder; the dispersing mechanism is mounted on the integrated component and includes a mounting frame, a dispersing component, and a screening component. The dispersing component is mounted on the integrated component via the mounting frame, and the screening component is installed inside the integrated component, with the dispersing component passing through the screening component. The dispersing component includes a drive motor, a transmission rod, a dispersing plate, and a feeding paddle. The drive motor is mounted on the mounting frame, the transmission rod is mounted at the output end of the drive motor, and the transmission rod passes through the integrated component and the screening component. The dispersing plate and the feeding paddle are both mounted on the transmission rod.

[0007] The reinforced modified polypropylene plastic granule melt extrusion device of this utility model can be assembled on the extruder through integrated components, and complete the dispersing and screening of agglomerated raw materials under the action of the dispersing mechanism. The dispersed and screened raw materials are discharged into the extruder through integrated components, thereby realizing the processing of plastic raw materials.

[0008] In addition, the melt extrusion apparatus for reinforced modified polypropylene plastic granules proposed in the application may also have the following additional technical features:

[0009] Specifically, the screening component includes a first screen plate and a second screen plate, wherein both the first screen plate and the second screen plate are disposed inside the integrated component, and the first screen plate is disposed above the second screen plate.

[0011] Specifically, the bottom end of the feeding cylinder is connected to a waste discharge box.

[0012] Specifically, support rods are installed at the four corners of the bottom of the waste discharge box.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The following description, in conjunction with the accompanying drawings, describes an embodiment of the reinforced modified polypropylene plastic granule melt extrusion apparatus.

[0021] The reinforced modified polypropylene plastic granule melt extrusion device provided in this embodiment can be applied to plastic processing. It can break up the raw materials during the feeding process, thereby ensuring the consistency of the raw material particle size during feeding and ensuring the quality of the plastic after melt extrusion.

[0022] like Figures 1-3 As shown, the enhanced modified polypropylene plastic granule melt extrusion device of this utility model embodiment may include an extruder 1, an integrated component 2, and a dispersing mechanism 3.

[0023] It should be noted that the extruder 1 described in the above embodiments is prior art, so it will not be described in detail.

[0024] The integrated component 2 is mounted on the extruder 1.

[0025] Understandably, the integrated component 2 facilitates the storage and unloading of raw materials.

[0026] The dispersing mechanism 3 is mounted on the integrated component 2. The dispersing mechanism 3 may include a mounting frame 31, a dispersing component 32, and a screening component 33.

[0027] The dispersing component 32 is mounted on the integrated component 2 via the mounting bracket 31, the screening component 33 is installed inside the integrated component 2, and the dispersing component 32 is set through the screening component 33.

[0028] Understandably, the installation of the dispersing component 32 is completed under the action of the mounting frame 31, and the dispersing and discharge of the raw materials are realized under the rotation of the dispersing component 32. During the dispersing process, the screening component 33 realizes the separation of the raw materials and the powder in the raw materials.

[0029] The dispersing assembly 32 may include a drive motor 321, a transmission rod 322, a dispersing plate 323, and a feeding paddle 324.

[0030] It should be noted that the disintegration plate 323 described in the above embodiments is provided in multiple sets.

[0031] The drive motor 321 is mounted on the mounting bracket 31, the transmission rod 322 is mounted on the output end of the drive motor 321, the transmission rod 322 passes through the integrated component 2 and the screening component 33, and the dispersing plate 323 and the feeding paddle 324 are both mounted on the transmission rod 322.

[0032] Understandably, driven by the drive motor 321, the transmission rod 322 drives the dispersing plate 323 and the feeding paddle 324 to rotate on the screening component 33. Then, under the action of the dispersing plate 323, the agglomerated raw material on the screening component 33 is dispersed, and under the action of the screening component 33, the dispersed raw material and powder are filtered. After filtration, the raw material is discharged through the rotating feeding paddle 324.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, the screening component 33 may include a first screen plate 331 and a second screen plate 332.

[0034] It should be noted that the dispersing plate 323 described in the above embodiment is located on the first screen plate 331, and the feeding paddle 324 is located on the second screen plate 332.

[0035] The first sieve plate 331 and the second sieve plate 332 are both disposed inside the integrated component 2, and the first sieve plate 331 is disposed above the second sieve plate 332.

[0036] Understandably, the first sieve plate 331 intercepts the agglomerated raw materials, thus facilitating the dispersing plate 323 to disperse the agglomerated raw materials. Subsequently, the second sieve plate 332 separates the dispersed raw materials and fine powders, and the material is discharged by the feeding slurry 324 after screening.

[0037] Specifically, in actual operation, personnel first pour the reinforced modified polypropylene plastic granules to be processed into the integrated component 2. Then, they start the drive motor 321 in the dispersing mechanism 3. The drive motor 321 drives the transmission rod 322 to rotate, and the multiple sets of dispersing plates 323 mounted on the transmission rod 322 rotate accordingly. Since the dispersing plates 323 are located on the first screen plate 331, during rotation, the dispersing plates 323 forcefully disperse the clumps of raw material, breaking them into smaller particles. The dispersed raw material and powder fall together through the first screen plate 331.

[0038] Next, the raw materials and powder continue to fall onto the second sieve plate 332. The sieve aperture size of the second sieve plate 332 is smaller than that of the first sieve plate 331, which can further sieve the dispersed raw materials and powder. The raw materials are retained on the second sieve plate 332, while the powder continues to fall through the second sieve plate 332.

[0039] At the same time, the feed paddle 324 installed on the transmission rod 322 is also rotating. The feed paddle 324 is located below the second screen plate 332. Its rotation can speed up the discharge speed of the raw material passing through the second screen plate 332, so that the raw material can smoothly enter the extruder 1 for subsequent melt extrusion processing.

[0040] The above-described embodiments can break up the raw materials during the feeding process, thereby ensuring the consistency of the raw material particle size during feeding and ensuring the quality of the plastic after melt extrusion.

[0041] In one embodiment of this utility model, such as Figure 1 As shown, the integrated component 2 may include a feeding cylinder 21, a discharge pipe 22, and a mounting plate 23.

[0042] It should be noted that the feed cylinder 21 described in the above embodiment is equipped with a cover plate (not shown in the figure) to shield the raw material during the raw material processing and prevent the raw material from splashing.

[0043] It should be noted that the mounting plate 23 described in the above embodiment is flush with the second screen plate 332, which facilitates the feeding of raw materials.

[0044] The feeding cylinder 21 is mounted on the extruder 1 via the mounting plate 23, and the discharge pipe 22 is connected to the feeding cylinder 21, with the downward inclined end of the discharge pipe 22 facing the extruder 1.

[0045] Understandably, the installation of the feed cylinder 21 on the extruder 1 is completed under the action of the mounting plate 23. Then the feed cylinder 21 stores the raw materials, which facilitates the dispersing of the raw materials. After that, the dispersing of the dispersed raw materials is achieved under the action of the discharge pipe 22.

[0046] Specifically, such as Figure 1 As shown, the bottom end of the feeding cylinder 21 is connected to the waste discharge box 4.

[0047] It should be noted that one end of the discharge box 4 described in the above embodiment is inclined, which facilitates the feeding of powder.

[0048] Furthermore, such as Figure 1 As shown, support rods are installed at the four corners of the bottom of the waste discharge box 4.

[0049] It should be noted that the support rods (not shown in the figure) described in the above embodiments are provided in four sets, thereby reducing the burden on the feed cylinder 21 on the extruder 1.

[0050] In summary, the reinforced modified polypropylene plastic granule melt extrusion device of this utility model can break up the raw materials during the feeding process, thereby ensuring the consistency of the raw material particle size during feeding and ensuring the quality of the plastic after melt extrusion.
