Technical Field
[0001] The utility model relates to the technical field of powder coating production, in particular to an extrusion device for powder coating production. Background Art
[0002] Powder coating is a form of coating material that is usually composed of fine solid particles, which are called powders. This coating usually does not contain solvents, but is applied directly to the surface of the object in the form of powder. Powder coating requires a baking or curing process after application to ensure that the coating forms a strong and durable protective layer on the surface. The extrusion device is one of the key equipment used in the production of powder coating. Its main function is to extrude the powder coating from a solid state and convert it into the desired shape, usually a continuous strip or profile.

DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-2 As shown, an extrusion device for producing powder coatings includes a base 1, a fixing frame 2 is fixedly connected to the top of the base 1, and a mixing barrel 3 is fixedly connected to the top of the fixing frame 2, and a heating ring 17 is fixedly connected to the outer wall of the mixing barrel 3. A stirring mechanism is arranged inside the mixing barrel 3, and the stirring mechanism includes an inner rod 9 and an outer rod 12. A motor 4 is fixedly connected to the top of the mixing barrel 3, and a rotating shaft 5 is fixedly connected to the output end of the motor 4. At the same time, a bracket 6 is fixedly connected to the top of the base 1, and the other end of the rotating shaft 5 is fixedly connected to a bevel gear 7, and the bevel gear 7 is rotatably connected to the inside of the bracket 6. A bevel gear 2 8 is fixedly connected to the outer top of the inner rod 9, and the bevel gear 2 8 is meshed with the bevel gear 7. The bevel gear 2 8 is rotatably connected to the inside of the bracket 6, and the outer rod 12 top The end is fixedly connected with bevel gear three 11, and bevel gear three 11 is meshed with bevel gear one 7, and bevel gear three 11 is rotatably connected to the inside of bracket 6, a feeding pipe 18 is fixedly connected to the top of mixing barrel 3, and inner rod 9 is rotatably connected to the inside of outer rod 12, and a pair of scraping rods 13 are fixedly connected to the outside of outer rod 12, and scraping rods 13 are slidably connected to the inner wall of mixing barrel 3, a pair of stirring rods 14 are fixedly connected to the outer wall of outer rod 12, a dragon leaf 15 is surrounded and connected to the bottom end of inner rod 9, and outer rod 12 penetrates mixing barrel 3 and extends to the inside of mixing barrel 3, a discharge pipe 16 is fixedly connected to the bottom of mixing barrel 3, dragon leaf 15 is rotatably connected to the inside of discharge pipe 16, and inner rod 9 penetrates mixing barrel 3 and extends to the inside of discharge pipe 16.
[0020] The powdered raw material is first poured into the mixing barrel 3 through the feed pipe 18, and the motor 14 on the top of the mixing barrel 3 is started, which drives the rotating shaft 5 and the bevel gear 17 to rotate. The movement of the bevel gear 17 causes the bevel gears 28 and 311 on the upper and lower sides to rotate in the opposite direction. The rotation of the bevel gear 28 drives the inner rod 9 to rotate. At the same time, the movement of the inner rod 9 causes the bottom dragon leaf 15 to start rotating. The rotation of the dragon leaf 15 inside the discharge pipe 16 effectively prevents blockage during material discharge. Under the rotation of the bevel gear 3 11, the outer rod 12 and the stirring rod 14 on the outer wall start to rotate. The movement of the stirring rod 14 makes the raw materials fully stirred. At the same time, the rotation of the outer rod 12 drives the scraping rods 13 on both sides to rotate and start scraping the inner wall of the mixing barrel 3 to ensure that the raw materials are fully integrated and improve the mixing quality. After the mixing is completed, by starting the heating ring 17, the raw materials in the mixing barrel 3 become liquid under the continuous heating of the heating ring 17, and then flow into the extruder through the discharge pipe 16. This system converts the powder raw materials into liquid state through mechanical stirring and heating in the whole process, providing a suitable material state for subsequent processes.
[0021] like Figure 3 As shown, a motor 20 is fixedly connected to one side of the base 1, and a spiral extrusion rod 21 is fixedly connected to the output end of the motor 20. At the same time, an extrusion barrel 19 is fixedly connected to the top of the base 1, and the spiral extrusion rod 21 is rotatably connected to the inside of the spiral extrusion rod 21. The discharge pipe 16 passes through the extrusion barrel 19 and extends to the inside of the extrusion barrel 19. The end of the extrusion barrel 19 is fixedly connected to the extrusion head 10, and the end of the spiral extrusion rod 21 is rotatably connected to the inner wall of the extrusion head 10.
[0022] The raw materials in the mixing barrel 3 are converted into a liquid state during the mixing process and flow into the interior of the extrusion barrel 19 through the discharge pipe 16. By starting the motor 20, the motor 20 causes the spiral extrusion rod 21 to start rotating and start conveying the raw materials in the liquid state. When the raw materials are conveyed to the position of the extrusion head 10, the raw materials are extruded. This process significantly improves the working efficiency through their synergistic effect. The entire system can effectively and smoothly extrude the raw materials in the liquid state to meet the needs of subsequent processing or manufacturing.
[0023] It should be noted that in actual use of the device, when the staff produces powder coatings, they first pour the powder raw materials into the mixing barrel 3 through the feed pipe 18, and then start the motor 4 on the top of the mixing barrel 3. Under the action of the motor 4, the rotating shaft 5 and the bevel gear 7 will be driven to rotate, and the rotation of the bevel gear 7 will drive the bevel gear 2 8 and the bevel gear 3 11 on the upper and lower sides to rotate in the opposite direction. When the bevel gear 2 8 rotates, the inner rod 9 inside will be driven to rotate, and the rotation of the inner rod 9 will drive the bottom dragon leaf 15 to rotate. The dragon leaf 15 rotates inside the discharge pipe 16, so as to prevent the problem of blockage when unloading. When the bevel gear 3 11 rotates, the outer rod 12 and the outer wall of the mixing The stirring rod 14 rotates, and the raw materials will be fully stirred through the rotation of the stirring rod 14. When the outer rod 12 rotates, the scraping rods 13 on both sides will be driven to rotate, and the inner wall of the mixing barrel 3 will be scraped to make it fully integrated and improve the quality. After the mixing is completed, the heating ring 17 will be started. Under the continuous heating of the heating ring 17, the raw materials inside the mixing barrel 3 will become liquid and then flow into the inside of the extrusion barrel 19 through the discharge pipe 16. Then, the motor 20 is started. Under the action of the motor 20, the spiral extrusion rod 21 will be driven to rotate, and the raw materials in the liquid state will be transported. When the raw materials are transported to the position of the extruder head 10, the raw materials will be extruded. Through the cooperation between them, the work efficiency is greatly improved.
