An integrated device for producing environment-friendly insulating and heat-conducting plastic

Abstract

This utility model discloses an integrated device for the production of environmentally friendly insulating and thermally conductive plastics, belonging to the technical field of plastic production equipment. It includes an injection molding machine with several heating jackets, and a mixing structure arranged at the injection molding machine's inlet for mixing the insulating and thermally conductive plastic raw materials. The mixing structure includes a material collection bin for centralized material storage and a discharge pipe arranged below the material collection bin on the injection molding machine's inlet. In use, the insulating and thermally conductive plastic raw materials can be added to two separate material distribution bins. By activating the motor, the rotating shaft and the linkage bevel gear can be controlled to rotate. The interaction between the linkage bevel gear and the driven bevel gear drives the material feeding plate in a circular motion, thereby controlling the continuous flow of material from the two distribution bins. This avoids excessive material being poured in at once, resulting in uneven mixing. The continuous rotation of the rotating shaft then causes the stirring rod to agitate the raw materials, improving the mixing effect.

Description

Technical Field

[0001] This utility model relates to the field of plastic production equipment technology, specifically to an integrated device for the production of environmentally friendly, insulating, and thermally conductive plastics. Background Technology

[0002] Environmentally friendly insulating and thermally conductive plastics are a new type of polymer material that combines environmental friendliness, excellent insulation performance, and efficient thermal conductivity. They are manufactured using bio-based or biodegradable resins as the base material, or by combining traditional engineering plastics with environmentally friendly modification techniques, and adding insulating and thermally conductive fillers such as boron nitride and alumina. These materials not only meet the insulation and heat dissipation requirements of electronics, new energy vehicles, and other fields, but also comply with environmental standards such as halogen-free flame retardancy and low VOCs, avoiding the environmental pollution problems of traditional plastics. They are widely used in LED heat dissipation components, power battery modules, and other applications.

[0003] Injection molding machines play a key role in the production of environmentally friendly insulating and thermally conductive plastics. They heat the plastics to a molten state and then inject them into a mold cavity under high pressure. After cooling and solidification, the desired product can be formed.

Detailed Implementation

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0055] Example 1:

[0056] like Figures 1 to 6 As shown, this utility model provides an integrated equipment for the production of environmentally friendly insulating and thermally conductive plastics, including: an injection molding machine 1, which is provided with a plurality of heating jackets 101, and a mixing structure arranged at the feed inlet of the injection molding machine 1 for mixing the insulating and thermally conductive plastic raw materials.

[0057] The mixing structure includes a material collection bin 2 for centralized storage of materials, a discharge pipe 201 arranged on the inlet of the injection molding machine 1, the discharge pipe 201 being arranged below the material collection bin 2, two distribution bins 202 arranged on the material collection bin 2, a motor 203 arranged above the material collection bin 2, a rotating shaft 204 arranged on the output end of the motor 203 and rotatably installed inside the material collection bin 2, and several stirring rods 205 evenly arranged on the rotating shaft 204. The materials in the two distribution bins 202 can fall into the material collection bin 2. Turning on the motor 203 can drive the rotating shaft 204 to rotate, and at the same time, the rotating shaft 204 can drive the stirring rods 205 to stir the materials in the material collection bin 2, promoting material mixing.

[0058] The mixing structure also includes a sealing component arranged inside the discharge pipe 201 for sealing the discharge pipe 201.

[0059] Specifically, the sealing assembly includes an L-shaped baffle 206 slidably installed inside the discharge pipe 201, and a multi-stage electric push rod 207 arranged on one side of the L-shaped baffle 206. The telescopic end of the multi-stage electric push rod 207 passes through the L-shaped baffle 206 and is arranged on one side of the discharge pipe 201. After the preheating, drying and mixing are completed, the multi-stage electric push rod 207 can be opened to drive the L-shaped baffle 206 to slide inside the discharge pipe 201, opening the discharge pipe 201 so that the mixed material can fall into the feed port of the injection molding machine 1.

[0060] Example 2:

[0061] Based on Example 1, in order to reduce the moisture content in the insulating and thermally conductive plastic raw material, a preheating structure for drying the raw material inside the mixing structure is arranged on the mixing structure.

[0062] The preheating structure includes a flow guide shroud 3 arranged on the injection molding machine 1, several heat conduction pipes 301 arranged on the corresponding heating jacket 101 and inside the flow guide shroud 3 for conducting heat from the heating jacket 101, a conveying pipe 302 arranged on one side of the flow guide shroud 3 with one end of the conveying pipe 302 arranged on the outer surface of the collection bin 2, several diversion pipes 303 arranged on the conveying pipe 302 and connected to the collection bin 2, and a fan 304 arranged on one side of the flow guide shroud 3 for blowing airflow into the flow guide shroud 3. When the injection molding machine 1 is in use, the heating jacket 101 needs to be turned on to heat and melt the mixed raw materials. The heat will be conducted to the heat conduction pipes 301. By turning on the fan 304, airflow can be blown into the flow guide shroud 3, so that the airflow passes through the heat conduction fins 306 and is heated. Then the hot airflow is blown into the collection bin 2 through the conveying pipe 302 and the diversion pipes 303 to preheat and dry the mixed materials in the collection bin 2.

[0063] The preheating structure also includes a heat-conducting plate 305 fixedly sleeved on the heat-conducting pipe 301 for conducting heat from the heat-conducting pipe 301, and several heat-conducting fins 306 arranged on one side of the heat-conducting plate 305 for dispersing heat from the heat-conducting plate 305. The heat from the heat-conducting pipe 301 can be conducted to the heat-conducting plate 305 through the heat-conducting pipe 301 and then dispersed onto the heat-conducting fins 306.

[0064] Example 3:

[0065] Based on Example 1, in order to improve the mixing effect of thermally conductive plastic raw materials, a feeding structure for controlling the continuous falling of materials is arranged on the mixing structure.

[0066] The material feeding structure includes an arc-shaped groove 4 inside the material distribution bin 202, a linkage shaft 401 rotatably installed inside the material distribution bin 202, a sleeve rod 402 fixedly sleeved on the linkage shaft 401, several material-pulling plates 403 evenly arranged on the sleeve rod 402 and in contact with the inner wall of the arc-shaped groove 4, and a linkage component arranged on the linkage shaft 401 to drive the linkage shaft 401 to rotate. Under the action of the linkage component, the linkage shaft 401 can rotate, so that the linkage shaft 401 can rotate the sleeve rod 402, and the sleeve rod 402 can drive the material-pulling plates 403 to move in a circular motion. During the process, the material can continuously fall from the material distribution bin 202.

[0067] Specifically, the linkage assembly includes a fixed housing 404 arranged on the inner wall of the collection bin 2, a driven bevel gear 405 arranged at one end of the linkage shaft 401 and located inside the fixed housing 404, and a linkage bevel gear 406 fixedly sleeved on the rotating shaft 204 and located inside the fixed housing 404. The linkage bevel gear 406 meshes with the driven bevel gear 405, and the rotating shaft 204 can drive the linkage bevel gear 406 to rotate. The rotating linkage bevel gear 406 can drive the two linkage shafts 401 to rotate by meshing with the two driven bevel gears 405.

[0068] Working principle:

[0069] In use, different raw materials for insulating and thermally conductive plastic are placed in two dispensing bins 202 respectively. The materials fall between the corresponding two feeding plates 403. By turning on the motor 203, the rotating shaft 204 is driven to rotate, which in turn drives the linkage bevel gear 406 to rotate. The rotating linkage bevel gear 406, through meshing with the two driven bevel gears 405, drives the two linkage shafts 401 to rotate, causing the linkage shafts 401 to rotate the sleeve rod 402. The sleeve rod 402 then drives the feeding plate 403 to move in a circular motion within the arc groove 4. During this process, the circularly moving feeding plate 403 continuously drives the material to fall from the dispensing bins 202, ensuring that the material in the two dispensing bins 202 continuously falls into the collection bin 2. At the same time, the rotating shaft 204 drives the stirring rod 205 to stir the material in the collection bin 2, promoting material mixing. The injection molding machine 1 requires the heating jacket 101 to be turned on during use. The mixed raw materials are heated and melted, and the heat is conducted to the heat pipe 301, then to the heat plate 305, and then dispersed onto the heat-conducting fins 306. By turning on the fan 304, airflow can be blown into the guide shroud 3, so that the airflow passes through the heat-conducting fins 306 and is heated. Then, the hot airflow is blown into the collection bin 2 through the conveying pipe 302 and the diversion pipe 303 to preheat and dry the mixed materials in the collection bin 2. The stirring rod 205 stirs the materials, promotes the material movement, and improves the preheating and drying effect of the materials. After the drying and mixing are completed, the multi-stage electric push rod 207 can be turned on, so that its telescopic end can be extended. The multi-stage electric push rod 207 can drive the L-shaped baffle 206 to slide in the discharge pipe 201, thereby opening the discharge pipe 201 and allowing the mixed materials to fall into the feed port of the injection molding machine 1 for the production and processing of insulating and heat-conducting plastics.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
