Description

Technical Field

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

[0002] Modified plastic products refer to products obtained by modifying plastics through physical or chemical methods. Modification can enhance the properties of plastics, such as strength, toughness, and heat resistance. Rapid prototyping equipment is equipment used for the efficient production of plastic products. It can convert plastic raw materials into molded products in a relatively short period of time. It usually includes a heating system, an injection molding system, a mold system, etc. By precisely controlling parameters such as temperature and pressure, the molten plastic is quickly injected into the mold, and the mold is quickly demolded after cooling and solidification, thereby achieving efficient production of modified plastic products and meeting the needs of modern industry for rapid production of plastic products.

[0003] During the processing of modified plastics, the introduction of raw materials and additives, as well as the influence of environmental factors, will cause the modified plastics to absorb a certain amount of moisture. They will also absorb moisture from the air during storage and transportation. However, existing rapid prototyping devices for modified plastic products are usually unable to effectively remove the moisture inside the modified plastics. The presence of moisture will increase the viscosity of the plastic when heated and melted, and its fluidity will deteriorate, which will in turn increase the injection molding pressure, making the molding of modified plastic products difficult.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-Figure 3 As shown, the utility model provides a modified plastic product rapid prototyping device, including a device body 1, the top of the device body 1 is fixedly connected to a processing box 2, the top of the processing box 2 is fixedly connected to an upper hopper 3, the top of the processing box 2 is fixedly connected to a heat insulation cover 4, the inner surface wall of the heat insulation cover 4 is fixedly installed with a group of infrared heating tubes 5, the top of the heat insulation cover 4 is provided with two mounting holes 6, and the inner surface walls of the two mounting holes 6 are. A reinforced fan 7 is fixedly inserted, and four mounting plates 8 are fixedly installed on the inner wall of the processing box 2. The inner walls of the four mounting plates 8 are movably contacted with rollers 9, and fixed rods 10 are movably inserted inside the four rollers 9. A mounting frame 11 is fixedly connected between one side of the outer wall of the four fixing rods 10, and a fixed seat 12 is fixedly installed on one side of the outer wall of the mounting frame 11. A connecting rod 13 is movably sleeved on the outer wall of the fixed seat 12, and a linkage rod 14 is movably inserted into the inner wall of the connecting rod 13. A rotating disk 15 is fixedly connected to one side of the outer wall of the linkage rod 14, and a driving motor 16 is fixedly inserted into the inner wall of the rotating disk 15. A screen 17 is fixedly connected to the inner wall of the mounting frame 11, and a discharge plate 18 is fixedly connected between one side of the outer wall of the mounting frame 11 and the screen 17.

[0023] The effect achieved by the entire embodiment 1 is that, first, the modified plastic particles and additives are accurately poured into the processing box 2 through the upper hopper 3, and then a group of infrared heating tubes 5 are connected to the power supply. At this time, the current flows through the heating wire, causing it to generate heat, thereby efficiently converting electrical energy into thermal energy. As the temperature of the heating wire increases, they will emit infrared radiation. This non-contact heating method can evenly and effectively dry the modified plastic to remove residual moisture therein, thereby avoiding defects caused by moisture evaporation in the subsequent molding process. Next, the drive motor 16 is started, and its output end drives the rotating disk 15 to rotate. Since a linkage rod 14 is eccentrically installed on one side of the outer wall of the rotating disk 15, and the outer wall of the linkage rod 14 is movably sleeved with a connecting rod 13, the rotation of the rotating disk 15 will drive the connecting rod 13 to reciprocate, and this movement is then transmitted to the mounting frame 11 and the screen 17, causing the screen 17 to vibrate continuously. This vibration prompts the material on the top of the screen 17 Continuously turning and dispersing, the modified plastic can slide evenly along the inclined surface of the screen 17, increasing the drying area and efficiency, and this vibration screening effect can also effectively remove some smaller impurities inside the modified plastic particles, ensuring the purity of the product in the subsequent processing process and the quality stability of the final product, and in this way, the infrared radiation generated by the infrared heating tube 5 can more fully act on various parts of the modified plastic, effectively removing the moisture therein. At the same time, the two enhanced fans 7 are started, and the strong airflow they generate forms heat convection in the processing box 2, which not only enhances the uniformity of heat transfer and distribution, but also further improves the drying effect. The accelerated effect of heat convection helps heat penetrate into the modified plastic faster, so that the moisture therein can be completely evaporated, thereby avoiding problems such as increased viscosity and poor fluidity caused by residual moisture during the heating and melting process. Finally, the modified plastic that has been fully dried and preheated is sent to the screw extruder 19 for subsequent molding processing.

[0024] Example 2, as Figure 2-Figure 3 As shown, the top of the device body 1 is fixedly connected to a screw extruder 19, the outer wall of the screw extruder 19 is fixedly connected to a barrel 20, the outer wall of the barrel 20 is provided with a feed port 21, the top of the barrel 20 is fixedly installed with a fixed plate 22, the top of the fixed plate 22 is fixedly installed with a stirring motor 23, and the output end of the stirring motor 23 is movably inserted into the inside of the fixed plate 22, the output end of the stirring motor 23 is fixedly connected to a stirring shaft 24, the outer wall of the stirring shaft 24 is fixedly sleeved with a spiral blade 25, and the output end of the barrel 20 is provided with an electric control valve 26.

[0025] The effect achieved by the entire embodiment 2 is that after the modified plastic particles and additives are dried, they are evenly slid from the discharge plate 18 into the barrel 20 through the continuous vibration of the screen 17. At this time, the stirring motor 23 is started, and its output end drives the stirring shaft 24 and the spiral blade 25 to rotate. The stirring shaft 24 and the spiral blade 25 work together to fully mix and stir the modified plastic particles and additive mixture inside the barrel 20. This process is intended to ensure that all components are evenly distributed and prevent performance differences caused by uneven components, thereby ensuring the quality consistency of the final product. At the same time, the special design of the spiral blade 25 not only realizes the mixing function, but also promotes the vertical transportation of the material. As the spiral blade 25 rotates, it can push the material at the bottom of the barrel 20 to move continuously upward. This action effectively avoids the deposition and agglomeration of the material at the bottom of the barrel 20, and further ensures the smoothness and stability of the modified plastic particles and additives in the subsequent processing by maintaining the fluidity and uniformity of the material.

[0026] Working principle: During the operation, the modified plastic particles and the required additives are first introduced into the processing box 2 through the upper hopper 3. Subsequently, the wires of a group of infrared heating tubes 5 are connected to the external power supply to energize them. The current flows through the built-in heating wire, efficiently converting electrical energy into thermal energy. As the temperature of the heating wire rises sharply, strong infrared radiation is released. This non-contact heating technology penetrates deep into the modified plastic particles, effectively removing moisture therein and ensuring the stability of the subsequent processing process. Immediately afterwards, the drive motor 16 is started, and its output end drives the rotating disk 15 to rotate. Since the linkage rod 14 eccentrically installed on one side of the outer wall of the rotating disk 15 and the connecting rod 13 movably sleeved on its outer wall form a linkage mechanism, coupled with the stable support and guiding effect of the four rollers 9 and the fixed rod 10, the connecting rod 13 drives the mounting frame 11 to reciprocate. This movement directly acts on the screen 17, causing it to vibrate continuously, prompting the material on the top of the screen 17 to continuously turn over and disperse, and slide smoothly along the inclined surface of the screen 17, thereby realizing the modified plastic particles. Uniform distribution and preliminary screening. At this time, the infrared radiation continuously emitted by the infrared heating tube 5, with the assistance of the vibration of the screen 17, more efficiently penetrates and acts on the modified plastic particles, further removes residual moisture, and optimizes its processing performance. At the same time, the two enhanced fans 7 are started, and the powerful airflow they generate forms a strong thermal convection effect in the processing box 2, which not only enhances the uniformity of heat transfer and distribution, but also accelerates the evaporation process of moisture inside the modified plastic particles. After completing the drying process, the modified plastic particles and additive mixture enters the barrel 20 smoothly through the discharge plate 18 under the continuous vibration of the screen 17. At this time, the stirring motor 23 is started, and its output end drives the stirring shaft 24 and the spiral blade 25 to rotate at a high speed, mixing and stirring the materials in the barrel 20 in an all-round and high-intensity manner. Finally, when the mixture is uniform, the mixture of the modified plastic particles and additives is sent to the screw extruder 19 for the next step of melt extrusion or molding processing through the precise control of the electric control valve 26, laying a solid foundation for the high-quality production of the final product.
