Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, specifically relating to an extrusion-type PP plastic processing device. Background Technology

[0002] PP plastic, chemically known as polypropylene, is a semi-crystalline thermoplastic polymer made from propylene monomers through an addition polymerization reaction. Polypropylene has properties such as being lightweight, wear-resistant, antibacterial, and easy to dye, and is widely used in fibrous products such as clothing and blankets. In the process of PP plastic processing, the raw materials need to be extruded and molded, which requires the use of extrusion PP plastic processing equipment.

[0003] Chinese Patent Publication No. CN218701106U discloses an extrusion device for EPP plastic processing, relating to the field of EPP plastic processing technology. This extrusion device includes an extrusion chamber and an extrusion assembly. A first insulation box is fixedly installed on the outer wall of the extrusion chamber, a support frame is fixedly installed at the bottom of the extrusion chamber, and a bracket is fixedly installed on the top of the support frame. The extrusion assembly is located below the first insulation box and includes a hydraulic rod and an extrusion block. By controlling the extension and retraction of the hydraulic rod, the extrusion block is pushed to the right. Through the coordinated use of the extrusion chamber, hydraulic rod, extrusion block, perforated plate, conveying pipe, and extrusion die, and by controlling the repeated extension and retraction of the hydraulic rod, the extrusion block propels the EPP plastic, thereby extruding the EPP plastic inside the extrusion chamber through the extrusion die. This avoids the accumulation of EPP plastic causing blockage of the perforated plate, and the continuous advancement of the extrusion block effectively improves the EPP plastic extrusion efficiency.

[0004] While the EPP plastic processing device mentioned above avoids the blockage of the perforated plate caused by the accumulation of EPP plastic, the device lacks a feeding structure. During the raw material addition process, there may be large pieces of material in the raw material. If these are not processed, they can easily block the feeding position and affect the smooth feeding. Therefore, we propose an extrusion-type PP plastic processing device. Utility Model Content

[0005] To address the problem mentioned in the background art where the device lacks a feeding structure, large pieces of material may be present in the raw material during the feeding process, easily clogging the feeding port and affecting smooth feeding. This invention provides an extrusion-type PP plastic processing device that installs a stirring motor and stirring shaft above the feeding box, and sets crushing blades on the outer wall of the stirring shaft. This allows for the crushing and stirring of the raw material during the feeding stage, effectively preventing large pieces of material from clogging the feeding port and ensuring smooth and efficient feeding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extrusion-type PP plastic processing device, including a processing box, a feeding box fixed above the processing box, heating boxes fixed on the outside of both the feeding box and the processing box, a stirring motor bolted to the middle of the upper part of the feeding box, a stirring shaft fixed to the output end of the stirring motor, and crushing blades fixed to the outer wall of the stirring shaft;

[0007] The feeding box has discharge ports on both sides below it. A discharge baffle is movably installed below the discharge port. A steering motor is installed in the middle below the discharge baffle. A drive motor is bolted to one side of the outer wall of the processing box. A spiral feeding rod is fixed to the drive end of the drive motor.

[0008] In a preferred embodiment of the extrusion-type PP plastic processing device of this utility model, the stirring motor forms a rotating structure between the stirring shaft and the crushing blades, and the heating box is closely fitted with the feeding box.

[0009] In a preferred embodiment of the extrusion-type PP plastic processing device of this utility model, the steering motor and the feeding baffle form a rotating structure, and the feeding baffle corresponds to the position of the feeding port.

[0011] In a preferred embodiment of the extrusion-type PP plastic processing device of this utility model, the drive motor and the spiral feed rod form a rotating structure, and the heating box and the processing box are closely fitted together.

[0012] As a preferred embodiment of the extrusion-type PP plastic processing device of this utility model, a discharge port is provided on one side of the bottom of the heating box, and an extrusion box is fixedly connected below the discharge port.

[0013] As a preferred embodiment of the extrusion-type PP plastic processing device of this utility model, a molding die is bolted to one side of the extrusion box, and a hydraulic rod is bolted to the other side of the extrusion box, with a push plate fixed to the output end of the hydraulic rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, the heating box outside the feeding box can realize the preheating of raw materials, improve the uniformity of PP plastic processing, and the stirring motor drives the stirring shaft to drive the crushing blades to pre-crush and mix the raw materials during the feeding stage, so as to avoid large particles from clogging the feeding port and prevent the device from lacking a feeding processing structure. During the raw material addition process, there may be large pieces of material in the raw materials. If they are not processed, they will easily block the feeding position and affect the smooth feeding. Attached Figure Description

[0027] Furthermore:

[0028] In an optional embodiment, the stirring motor 4 forms a rotating structure between the stirring shaft 5 and the crushing blades 6, and the heating box 3 is closely fitted with the feeding box 2.

[0029] In this implementation plan: the stirring motor 4 drives the stirring shaft 5 to drive the crushing blades 6, which pre-crush and mix the raw materials during the feeding stage to ensure that the raw materials are finely crushed and to avoid large particles from clogging the feed inlet 7. At the same time, the heating box 3 can preheat the materials in the feed box 2.

[0030] Furthermore:

[0031] In an optional embodiment, the steering motor 9 and the discharge baffle 8 form a rotating structure, and the position of the discharge baffle 8 corresponds to that of the discharge port 7.

[0032] In this implementation scheme: the steering motor 9 can drive the discharge baffle 8 to rotate, thereby facilitating the opening and closing of the discharge port 7.

[0033] Furthermore:

[0034] In an optional embodiment, the feed box 2 is interconnected with the processing box 1 via the discharge port 7.

[0035] In this implementation plan: the discharge port 7 can facilitate direct connection between the feed box 2 and the processing box 1.

[0036] Furthermore:

[0037] In an optional embodiment, the drive motor 10 and the screw feed rod 11 form a rotating structure, and the heating box 3 and the processing box 1 are in close contact.

[0038] In this implementation scheme: the drive motor 10 can drive the spiral feed rod 11 to rotate, which facilitates pushing the material to one side. At the same time, the heating box 3 can continuously heat the material in the processing box 1 to promote the melting of PP plastic.

[0039] Furthermore:

[0040] In an optional embodiment, a discharge port 12 is provided on one side of the bottom of the heating box 3, and an extrusion box 13 is fixedly connected below the discharge port 12.

[0041] In this embodiment, the molten PP plastic can be directly conveyed to the extrusion box 13 through the discharge port 12.

[0042] Furthermore:

[0043] In an optional embodiment, a forming mold 14 is bolted to one side inside the extrusion box 13, and a hydraulic rod 16 is bolted to the other side outside the extrusion box 13. A pusher plate 15 is fixed to the output end of the hydraulic rod 16.

[0044] In this embodiment, the hydraulic rod 16 can drive the pusher plate 15 to push the molten material into the molding die 14, which facilitates the extrusion molding of plastic.

[0045] Working principle: First, the plastic raw material is fed into the feeding box 2 through the feeding mechanism. At the same time, the heating element in the heating box 3 is energized. The heating element in the heating box 3 is an electric heating rod. Then, the stirring motor 4 is started. The stirring motor 4 drives the stirring shaft 5 to drive the crushing blades 6 to rotate at high speed, pre-crushing and mixing the PP plastic raw material in the feeding box 2, breaking large pieces of material into fine particles to avoid clogging the discharge port 7. At the same time, the heating element preheats and softens the material in the feeding box 2, which facilitates the improvement of subsequent melting efficiency. Next, the steering motor 9 is started. The steering motor 9 drives the discharge baffle 8 to rotate to a position away from the discharge port 7, which opens the discharge port 7, and the material falls from the feeding box 2 into the processing box 1. Then, the drive motor 10 is started, which drives the spiral feed rod 11 to rotate, pushing the material in the processing box 1 towards the discharge end. At the same time, the heating box 3 outside the processing box 1 continuously heats the material, promoting the PP plastic to a molten state. The molten PP plastic enters the extrusion box 13 directly through the discharge port 12. Finally, the hydraulic rod 16 is started, which drives the push plate 15 to move towards the molding die 14, thus pushing the material in the extrusion box 13 into the molding die 14 with constant pressure. The material is extruded into the required shape through the die hole and discharged. The molding die 14 and the extrusion box 13 can be disassembled with bolts, making it easy to replace different extrusion dies as needed.
