Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a multi-component uniform mixing device for the preparation of PEEK composite materials. Background Technology

[0002] PEEK composite material is a high-performance engineering plastic, also known as polyether ether ketone. It has good heat resistance, plasticity and strength, and is a high-quality resin material. It is often used in aerospace, medical and other fields. PEEK composite material is made by mixing and stirring multiple materials.

[0003] Existing PEEK composite material preparation mixing devices, such as the raw material mixing device for PEEK materials disclosed in publication number CN214926007U, have the advantages of facilitating subsequent cleaning, reducing workload, and improving efficiency. However, this mixing device is not convenient for breaking up multiple groups of materials during feeding to ensure uniform mixing between the materials. In addition, the brush head at the bottom of its bucket lid is installed in the mixing inner bucket, which will also affect the mixing uniformity at the corners of the mixing inner bucket. Therefore, we propose a multi-component uniform mixing device for the preparation of PEEK composite materials. Utility Model Content

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a multi-component uniform mixing device for the preparation of PEEK composite materials.

[0026] Example 1:

[0027] Combination Figure 1-5 As shown, this utility model provides a multi-component uniform mixing device for the preparation of PEEK composite materials, comprising: a device body 100 and a stirring assembly 200; the device body 100 includes a stirring tank 101, a sealing cover 102 movably installed on the top of the stirring tank 101, a base 103 fixedly installed on the bottom of the stirring tank 101, and a control box 104 fixedly installed on one side of the base 103; the stirring assembly 200 includes a motor 201 fixedly installed at the center of the top of the sealing cover 102, a drive shaft 202 fixedly connected to the bottom of the motor 201, a frame-type stirring paddle 203 fixedly installed at the lower part of the drive shaft 202, side paddles 204 fixedly installed on both sides of the frame-type stirring paddle 203, a lower paddle rod 205 fixedly installed at the bottom of the frame-type stirring paddle 203, a dispersing blade 206 fixedly installed at the upper end of the drive shaft 202, and a discharge cover fixedly installed at the bottom of the sealing cover 102. 207. A discharge port 208 is fixedly installed on the upper end of the sealing cover 102, and the discharge port 208 is located on the upper part of the discharge cover 207. A threaded cover 209 is movably installed on the outer end of the discharge port 208. An upper scraper 210 is fixedly installed on one side of the frame-type stirring paddle 203. Fixed ears 211 are fixedly installed on both ends of the sealing cover 102. Electric push rods 212 are fixedly installed at the bottom of the fixed ears 211, and the bottom of the electric push rods 212 is fixed on the base 103. Multiple sets of positioning columns 213 are also fixedly installed at the bottom of the sealing cover 102. Multiple sets of positioning holes 214 are also arranged at the upper end of the stirring tank 101, and the positioning holes 214 and positioning columns 213 are matched. A sealing gasket 215 is also fixedly installed at the bottom of the sealing cover 102. The side paddles 204 on both sides of the frame-type stirring paddle 203 are staggered. The drive shaft 202 is movably connected to the sealing cover 102.

[0028] Specifically, PEEK composite material is a high-performance engineering plastic, also known as polyetheretherketone. In its preparation, PEEK composite material requires mixing and stirring multiple materials. In this preparation, materials are sequentially added through the discharge port 208 and uniformly discharged into the discharge hood 207 at the bottom of the sealing cover 102. After being discharged from the bottom of the discharge hood 207, they are evenly dispersed by the dispersing blades 206 rotating on the bottom drive shaft 202, ensuring uniform dispersion of the multiple materials. Simultaneously, the lower lever 205 at the bottom of the frame-type stirring paddle 203 can also stir and mix the various materials discharged to the bottom of the mixing tank 101 after discharge, ensuring uniform mixing before stirring. During the stirring of materials in the mixing tank 101, the side levers 204 staggered at both ends of the frame-type stirring paddle 203 and the lower lever 205 installed at the bottom of the frame-type stirring paddle 203 can also circulate and stir the side walls and bottom walls of the mixing tank 101. The scraping action agitates materials in hard-to-reach areas, ensuring uniform mixing. The side scrapers 204, upper scraper 210, and lower lever 205 on the frame-type mixing paddle 203 can also be used for cleaning the inner wall of the mixing tank 101. The threaded cap 209 at the upper end of the discharge port 208 is mainly used for sealing the discharge port 208. The electric push rods 212 at both ends of the sealing cover 102 are mainly used for opening and closing the sealing cover 102, and are used to drive the lower end of the sealing cover 102 and the frame-type mixing paddle. The convenient maintenance and inspection of the paddle 203, the positioning pins 213 arranged and installed at the bottom of the sealing cover 102, and the positioning holes 214 arranged and opened on the mixing tank 101 can be used for positioning and installing the sealing cover 102 at the top of the mixing tank 101, and can also be used for the stable binding of the sealing cover 102, thereby ensuring the stability of the bottom drive shaft 202 during rotation. The sealing gasket 215 fixedly installed at the bottom of the sealing cover 102 is mainly used to ensure the seal between the sealing cover 102 and the mixing tank 101.

[0029] Working principle and usage process of this utility model:

[0030] In the preparation of PEEK composite materials, the motor 201 is first started to rotate the drive shaft 202 inside the mixing tank 101. While the drive shaft 202 is rotating, multiple sets of materials are sequentially added through the discharge port 208. The materials added through the discharge port 208 first flow into the bottom discharge hood 207 and are then uniformly discharged at the bottom of the discharge hood 207. After the materials are vertically discharged along the bottom of the discharge hood 207, they first fall onto the rotating dispersion blades 206 at the bottom, where they are dispersed. The material falling from the bottom of the mixing tank 101 can also be stirred and mixed by the bottom rotating lever 205. After the material is added, during the stirring, the side blades 204 arranged alternately on both sides of the frame-type stirring paddle 203 can scrape the inner wall of the mixing tank 101 in sequence, while the bottom lever 205 can also scrape the inner wall and bottom wall of the mixing tank 101, thereby scraping and mixing the material at the four corners of the mixing tank 101, thereby improving the uniformity of material mixing during the stirring of the main body 100 of this device.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
