Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mixing equipment technology, and relates to an integrated mixing and extrusion equipment, particularly an integrated high-speed mixing and extrusion equipment for temperature-controlled and heat-insulating masterbatch. Background Technology
[0002] Thermal insulation masterbatch is a type of functional plastic granule with added special thermal insulation materials (such as ceramic microspheres and aerogels). It effectively reduces the thermal conductivity of plastic products, blocks heat transfer, and maintains the material's processability. It can be directly mixed into ordinary plastic raw materials and used in processes such as injection molding and extrusion to produce products with thermal insulation properties.
[0003] During the extrusion process, the material enters the barrel through the feeding system. The barrel is equipped with a heating and temperature control structure. Through the conveying, shearing and mixing action of the screw, conventional mixing mechanisms use a single screw to radially mix multiple materials, which requires a long mixing chamber and mixing time to ensure the full integration of materials. The long mixing chamber makes temperature control within the mixing chamber more difficult. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an integrated high-speed mixing and extrusion equipment for temperature-controlled and heat-insulating masterbatch.
[0005] The objective of this utility model can be achieved through the following technical solution: a high-speed mixing and extrusion integrated equipment for temperature-controlled heat-insulating masterbatch, characterized in that it includes a barrel, inside which a spiral blade A is provided, and a stirring rod is also provided inside the barrel, on which two parallel spiral blades B are provided, both the spiral blades A and B have through grooves, the through grooves divide the spiral blades A and B into multiple spiral spokes, the pitch of the spiral blades A is greater than that of the spiral blades B, several feed pipes are provided on the side wall of the barrel, and a control motor is provided at the top of the stirring rod.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0020] like Figures 1-6 As shown, this temperature-controlled, heat-insulating masterbatch high-speed mixing and extrusion integrated equipment includes a barrel 3. Inside the barrel 3 are spiral blades A7 and a stirring rod 10, on which are two parallel spiral blades B11. Both spiral blades A7 and B11 have through-grooves 20, which divide them into multiple spiral spokes 19. The pitch of spiral blade A7 is greater than that of spiral blade B11. Several feed pipes 2 are located on the side wall of the barrel 3. A control motor 1 is located at the top of the stirring rod 10. Before operation, the motor rotates and preheats the barrel 3. The spiral blades rotate continuously. During operation, materials are added through the feed pipe 2. Due to the different pitches of the spiral blades A7 and B11, they will collide at some points, causing the stirring rod 10 to move downwards as a whole. The distance between the spiral blades B11 and A7 will gradually change until the spiral spokes 19 enter the through groove 20. The stirring rod 10 then moves downwards and resets. As the stirring rod 10 continues to work, the spiral blades A7 and B11 will collide again and mix the materials. The upper spiral blade of the parallel spiral blade B11 will approach the bottom of the spiral blade A7 during the mixing process, further increasing the mixing efficiency.
[0021] Preferably, the top of the barrel 3 is provided with a sealing cover 8, the side wall of the sealing cover 8 is provided with a connecting thread 21, and the sealing cover 8 is provided with a hexagonal hole 9. The sealing cover 8 and the connecting thread 21 protrude from the top of the barrel 3. The stirring rod 10 protrudes from the sealing cover 8 and is connected to the control motor 1. The control motor 1 is provided with a fixing thread 6, and the fixing thread 6 and the connecting thread 21 are interlocked. The sealing cover 8 increases the airtightness, and the control motor 1 and the barrel 3 are connected by the thread on the sealing cover 8.
[0022] Preferably, the barrel 3 is provided with a support crossbar 18, a limiting block 17 is provided on the support crossbar 18, a spring 16 is engaged on the limiting block 17, a support tray 12 is provided at the bottom of the stirring rod 10, and the top of the spring 16 abuts against the support tray 12, so that the spring 16 makes the stirring rod 10 return to its original position more quickly.
[0023] Preferably, the bottom of the barrel 3 is provided with an extrusion screen 5, and the extrusion screen 5 and the side wall of the barrel 3 are provided with quick-release buckles 4. The quick-release buckles make it easier to replace the extrusion screen 5, and at the same time facilitate the penetration and maintenance of internal components.
[0024] Preferably, the edges of the spiral spokes 19 are provided with a guide angle 15 and a guide radius 13.
[0025] Preferably, the end of the stirring rod 10 is provided with a connecting spline 14, which is connected to the control motor 1 so that the motor can continuously drive when the stirring rod 10 moves up and down.
[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
