Description

Technical Field

[0001] The invention relates to the technical field of plastic production, and in particular discloses an extrusion molding device for environmentally friendly and degradable plastics. Background Art

[0002] Plastic is a type of synthetic resin, and its shape is similar to the pine resin in natural resin. It is artificially synthesized by chemical means and is called plastic. Plastic is a high molecular compound polymerized by addition or condensation reaction with monomers as raw materials, commonly known as plastic or resin, which can freely change its composition and shape. Nowadays, plastic molding is mostly achieved by extruders. Plastic extruders are also a type of plastic machinery. The extruder head can be divided into right-angle head and bevel head according to the direction of the material flow in the head and the angle between the center line of the screw. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then form it through the die.

[0003] If there is less material in the existing plastic during the heating process, it will lead to uneven heating. The existing feed port and barrel are mostly fixed structures, making it difficult to clean and repair the barrel separately. In addition, most existing extruders rely on manual feeding, where the raw materials are fed into the feed port and then transferred to the inside of the extruder for melting and extrusion. However, the existing extruders cannot adjust the amount of raw materials fed according to the extrusion rate of the extruder. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide an extrusion molding device for environmentally friendly and degradable plastics.

[0005] To achieve the above-mentioned purpose, the present invention provides an extrusion molding equipment for environmentally friendly and degradable plastics, including a bracket and an auger module and a feeding module arranged on the bracket, the auger module and the feeding module are respectively used for conveying, mixing and unloading external materials; the bracket is also provided with a driving module for controlling the operating status of the auger module and the feeding module, the auger module includes a barrel for conveying and heating external materials, and a heating component is provided on the barrel, and the heating component includes a first heating component and a second heating component arranged at both ends of the barrel.

[0006] Preferably, the bracket includes a first frame and a second frame arranged on the first frame, the first frame and the second frame are respectively used for the setting of the auger module and the feed module, the feed module is arranged on the second frame, and the feed module is connected to the auger module for realizing external material supply. The layered design optimizes the overall layout of the equipment, so that the auger module and the feed module can be installed on the bracket in an orderly manner, which not only reduces the footprint, but also improves space utilization. At the same time, modular assembly is also conducive to subsequent disassembly and maintenance.

[0007] Preferably, the auger module also includes a discharge piece arranged at the end of the cylinder, which is connected to the cylinder via an external connecting piece. A sealing piece for sealing is provided between the discharge piece and the cylinder. The setting of the sealing piece effectively prevents leakage of material at the connection between the discharge piece and the cylinder, avoids material waste and environmental pollution, and ensures the continuity and stability of the extrusion molding process. The reliable connection between the discharge piece and the cylinder is achieved through the external connecting piece, which is not only convenient for installation and disassembly, but also helps in maintenance and inspection of the equipment, reducing maintenance costs. When materials of different shapes need to be extruded, only the discharge piece needs to be disassembled and replaced.

[0008] Preferably, the auger module includes a first shaft rotatably arranged on the second frame, the first shaft is provided with a spiral blade, one end of the first shaft with the blade is accommodated in the cylinder, the axial direction of the first shaft is parallel to the axial direction of the cylinder, the rotation of the first shaft drives the spiral blade to rotate, the spiral structure of the blade enables the material to be pushed stably along the axial direction in the cylinder, realizing continuous and uniform material transportation, the axial direction of the first shaft is parallel to the axial direction of the cylinder, ensuring the stability and consistency of the material transportation direction, and avoiding the deviation and accumulation of the material during the transportation process.

[0009] Preferably, the inner wall of the cylinder is provided with a plurality of them, which are arranged in a ring array on the cylinder and are formed with the cylinder through an integrated structure to increase the heating area of ​​the material inside the cylinder, thereby improving the heat transfer efficiency and allowing the material to be heated more evenly and quickly during the extrusion process, thereby optimizing the extrusion molding effect and improving the quality and production efficiency of the product. At the same time, the integrated structure enhances the structural strength of the cylinder and improves the durability and stability of the equipment.

[0010] Preferably, the first heating element is arranged at the end of the cylinder away from the discharge piece. The first heating element is an electric heating wire. The temperature of the first heating element gradually increases from the end of the cylinder away from the discharge piece to the end of the cylinder close to the discharge piece, which can ensure that the material is gradually heated from the low temperature zone to the high temperature zone in the cylinder, realizing temperature gradient control, avoiding thermal degradation or thermal deformation of the material due to sudden high temperature, and ensuring the quality and stability of the extruded product. At the same time, this temperature gradient design also helps to uniformly heat and fully melt the material in the cylinder, thereby improving extrusion efficiency and product quality.

[0011] Preferably, the second heating element is arranged at one end of the cylinder near the discharge element. The second heating element is arranged around the cylinder to maintain the internal temperature of the cylinder within the melting temperature range of the plastic material.

[0013] Preferably, a second shaft is provided in the sleeve, and the sleeve is set on the second shaft via external bolts. The second shaft is provided with a second gear at one end close to the driving module and passes through the feed hopper. There are two feed modules, and the second gears of the two feed modules are meshed with each other. The second shaft of one of the feed modules is driven to rotate by the driving module. Since the second gears of the two feed modules are meshed with each other, the other feed module can be driven to rotate synchronously, thereby realizing uniform material discharge at the feed port, which not only improves the stability and consistency of material supply, but also helps to optimize the extrusion molding process and improve product quality and production efficiency.

[0014] Preferably, a transmission member is rotatably provided on the feed hopper, and a first gear is provided at the end of the first shaft away from the discharge member. The first gear is transmitted to the second gear via the transmission member, thereby realizing linkage control between the auger module and the feed module. When the drive module is started and drives the first shaft to rotate, the first gear rotates accordingly, and drives the second gear to rotate through the transmission member, thereby driving the sleeve and the discharge member of the feed module to rotate, thereby realizing uniform discharge of materials. This linkage control method not only simplifies the operating process of the equipment and improves production efficiency, but also ensures the coordination between material supply and auger conveying, avoids extrusion molding problems caused by insufficient or excessive material supply, thereby improving the quality and stability of extruded products.

[0015] The beneficial effects of the present invention are as follows: a heating component is provided on the barrel, which can ensure that the material is evenly heated to a suitable molten state during the conveying process, thereby improving the extrusion efficiency and product quality. The first heating component is usually arranged away from the discharge end for initial heating of the material entering the barrel, while the second heating component is arranged close to the discharge end for maintaining the molten state of the material before extrusion, and the temperature can be fine-tuned as needed to ensure the stability and consistency of the extruded product. This design of heating at both ends not only improves the heating efficiency, but also makes the temperature control more precise, which helps to optimize the extrusion molding process.

At the same time, this temperature gradient design also helps to uniformly heat and fully melt the material in the cylinder, thereby improving extrusion efficiency and product quality.

[0031] Specifically, in this embodiment, the first heating element 51 realizes a gradient increase in heating temperature from the end of the cylinder 24 away from the discharge piece 25 to the end of the cylinder 24 close to the discharge piece 25 through the density of the electric heating wire.
