Description

Technical Field

[0001] This utility model relates to the technical field of thermal conductive silicone extrusion equipment, specifically an anti-clogging thermal conductive silicone production conveying extruder. Background Technology

[0002] Silica gel, also known as silica gel, is a highly active adsorbent material. It is an amorphous substance with the chemical formula mSiO2·nH2O. Except for strong alkalis and hydrofluoric acid, it does not react with any substance, is insoluble in water and any solvent, is non-toxic and odorless, and has stable chemical properties.

[0003] Thermally conductive silicone is a silicon-based material with high thermal conductivity, widely used in electronic devices and industrial applications requiring efficient heat dissipation. It primarily improves heat dissipation efficiency by filling the gaps between electronic components and heat sinks, increasing the contact area, and reducing thermal resistance. Thermally conductive silicone also possesses excellent thermal conductivity, electrical insulation, flexibility, and weather resistance, making it an ideal material for thermal management of electronic devices.

[0004] Thermally conductive silicone requires an extruder for production. Traditional thermally conductive silicone extrusion equipment is incomplete in function. During the extrusion process, it cannot continuously heat the thermally conductive silicone, which leads to cooling during the conveying process. The cooled thermally conductive silicone can clog the internal conveying structure, affecting the normal extrusion effect. In addition, a single extruder can only extrude silicone material of the same specification and size, resulting in insufficient structural applicability and significant limitations.

[0005] The purpose of this invention is to provide an anti-clogging thermal conductive silicone production conveying extruder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-clogging thermally conductive silicone production conveying extruder, comprising a conveying cylinder, wherein the conveying cylinder has a hollow internal structure and a cylindrical external structure. The conveying cylinder has several heating channels inside, and each heating channel is fixedly installed with an internal heating rod. The number of internal heating rods is not less than four. One end of the conveying cylinder is provided with a cylinder discharge end, the inside of which is provided with an internal thread. An extrusion head is provided on the outside of the cylinder discharge end, and the side of the extrusion head near the cylinder discharge end is provided with an external thread. The extrusion head and the cylinder discharge end are detachably connected via the thread. A spiral auger is provided inside the conveying cylinder.

[0007] Preferably, an outer end cover is fixedly installed on the outer wall of the other end of the conveying cylinder, and a conveying motor is fixedly installed at the center of the outer surface of the outer end cover by bolts.

[0008] Preferably, the output shaft of the material conveying motor is fixedly connected to the spiral auger blades.

[0009] Preferably, the upper surface of the feeding cylinder near the outer end cap is provided with a feeding port, and the feeding port adopts a funnel-shaped structure design.

[0010] Preferably, the lower surface of the bottom end of the injection port is interconnected with the interior of the conveying cylinder through a feeding channel.

[0011] Preferably, the feed cylinder is surrounded by a reinforcing mesh.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes an internal heating rod to continuously heat the thermally conductive silicone inside the feeding cylinder, effectively preventing the silicone from cooling during the feeding process and avoiding internal blockage caused by cooled silicone. Simultaneously, continuous heating maintains the silicone's flexibility, thus improving the smoothness of subsequent extrusion. This results in better practical performance, increased extrusion and discharge efficiency, and enhanced usability.

[0014] Meanwhile, the extrusion head and the discharge end of the cylinder of this utility model are detachably connected by threads. In actual use, extrusion heads of different sizes or shapes can be replaced according to actual production and usage needs. This allows the extruder of this utility model to produce thermally conductive silicone materials of different sizes or shapes by changing the extrusion head. In actual implementation, it has the practical effect of single machine and multi-specification production, effectively avoiding the limitation of traditional extruders that can only produce materials of a single size. It effectively improves the practical application range of this utility model, has good multi-size production practicality, is more convenient to use, has fewer limitations in machine use, and the threaded connection structure has the characteristics of quick installation and disassembly.

[0024] Please see Figure 1-5 One embodiment of this utility model is a non-clogging thermal conductive silicone production conveying extruder, which includes a conveying cylinder 1. In order to improve the structural strength of the conveying cylinder 1, a reinforcing mesh is provided around the outside of the conveying cylinder 1. The inside of the conveying cylinder 1 is a hollow structure design, and the outside of the conveying cylinder 1 adopts a cylindrical structure design.

[0025] Please refer to the instruction manual for details. Figure 3As shown, in order to continuously heat the thermally conductive silicone inside the feeding cylinder 1 and prevent it from cooling during the feeding process, the feeding cylinder 1 is provided with several heating channels. Each heating channel is fixedly installed with an inner heating rod 2, and the number of inner heating rods 2 is not less than four.

[0026] This structural design, through the internal heating rod 2, can effectively and continuously heat the thermally conductive silicone inside the feeding cylinder 1. This effectively prevents the thermally conductive silicone from cooling down during the feeding process, thus avoiding internal blockage caused by cooled thermally conductive silicone. At the same time, continuous heating can also ensure the softness of the thermally conductive silicone, thereby effectively improving the smoothness of subsequent extrusion. It has a better practical effect, improves the smoothness of extrusion and discharge, and has better practicality.

[0027] And refer to the instruction manual attached. Figure 3 It can be seen that the inner heating rod 2 of this utility model is distributed in a circumferential ring structure, which can effectively improve the heating uniformity of the thermally conductive silicone and effectively improve the performance.

[0028] One end of the conveying cylinder 1 is provided with a cylinder discharge end 3. The inside of the cylinder discharge end 3 is provided with an internal thread 4. The outside of the cylinder discharge end 3 is provided with an extrusion head 5. The side of the extrusion head 5 near the cylinder discharge end 3 is provided with an external thread 6. The extrusion head 5 and the cylinder discharge end 3 are detachably connected through the thread.

[0029] This structural design, through the extrusion head 5, allows for the final extrusion and discharge of thermally conductive silicone. The extrusion head 5 can extrude thermally conductive silicone material of a specified shape or size. Furthermore, the extrusion head 5 is detachably connected to the discharge end 3 of the cylinder via a thread. In actual use, different sizes or shapes of extrusion heads 5 can be replaced according to actual production and usage needs. This allows the extruder to produce thermally conductive silicone material of different sizes or shapes through replacement. In practice, it offers the practical effect of single-machine, multi-specification production, effectively avoiding the limitations of traditional extruders that can only produce single-size materials. This significantly improves the applicability of this invention, providing better multi-size production practicality, greater ease of use, fewer machine limitations, and the threaded connection structure allows for quick installation and disassembly. The extrusion head 5 can be quickly replaced, making the structure more convenient to use, with fast replacement speed and high efficiency.

[0030] In this embodiment, in order to ensure the normal material conveying operation of the material conveying cylinder 1 of this utility model, a spiral auger plate 8 is provided inside the material conveying cylinder 1;

[0031] An outer end cover 9 is fixedly installed on the outer wall of the other end of the feeding cylinder 1. A feeding motor 10 is fixedly installed at the center of the outer surface of the outer end cover 9 by bolts. The output shaft of the feeding motor 10 is fixedly connected to the spiral auger plate 8.

[0032] The feeding motor 10 can drive the spiral auger 8 to rotate through its output shaft. When the spiral auger 8 rotates, it can convey the heat-conducting silicone material inside the cylinder in a spiral manner, ensuring normal feeding effect.

[0033] In this embodiment, in order to facilitate the injection of thermally conductive silicone material, an injection port 7 is provided on the upper surface of the feeding cylinder 1 near the outer end cap 9. The injection port 7 adopts a funnel-shaped structure design, and the lower surface of the bottom end of the injection port 7 is interconnected with the interior of the feeding cylinder 1 through the feeding channel 11.

[0034] Working principle: When using this utility model, the thermally conductive silicone material to be extruded can be injected into the inside of the conveying cylinder 1 of this utility model through the injection port 7. At this time, the conveying motor 10 can drive the spiral auger 8 to rotate through its output shaft. When the spiral auger 8 rotates, it can convey the thermally conductive silicone material inside the cylinder in a spiral manner to ensure normal conveying effect.

[0035] After being fed, the thermally conductive silicone material will eventually be discharged through the extrusion head 5, thereby completing the spiral conveying and extrusion work of the extruder of this utility model. Through the structural design of the extrusion head 5, thermally conductive silicone material of a specified shape or size can be extruded, thereby meeting the work requirements of silicone material production extrusion of specified size.

[0036] This invention utilizes an internal heating rod 2 to continuously heat the thermally conductive silicone inside the feeding cylinder 1, thereby preventing the silicone from cooling during the feeding process and avoiding internal blockage caused by cooled silicone. Continuous heating also maintains the silicone's flexibility, effectively improving the smoothness of subsequent extrusion. This results in better practical performance, improved extrusion and discharge flow, and enhanced usability.

[0037] Meanwhile, the extrusion head 5 and the discharge end 3 of the cylinder are detachably connected by threads. In actual use, extrusion heads 5 of different sizes or shapes can be replaced according to actual production and usage needs. This allows the extruder of this invention to produce thermally conductive silicone materials of different sizes or shapes by changing the extruder. In actual implementation, it has the practical effect of single machine and multi-specification production, effectively avoiding the limitation of traditional extruders that can only produce materials of a single size. It effectively improves the practical application range of this invention, has good multi-size production practicality, is more convenient to use, has fewer limitations in machine use, and the threaded connection structure has the characteristics of quick installation and disassembly. The extrusion head 5 can be quickly disassembled and replaced, making the structure more convenient to use, with fast replacement speed and high efficiency.
