[0006] As a preferred embodiment of the polyetheretherketone resin processing aid mixing device of this utility model, the mixing cylinder is fixedly provided with two sets of symmetrical first screws at its upper end, the upper ends of the first screws movably pass through the cylinder cover, and the upper ends of the first screws are threaded with first nuts.

[0007] In a preferred embodiment of the polyetheretherketone resin processing aid mixing device of this utility model, the upper end of the first bevel gear is rotatably connected to the connecting plate, the second bevel gear meshes with the first bevel gear and the third bevel gear respectively, the first rotating rod is rotatably inserted into the middle end of the cylinder cover, the second rotating rod moves from top to bottom through the third bevel gear and the first rotating rod, and the output ends of the dual-shaft motor are respectively connected to the pinion and the second bevel gear.

[0008] As a preferred embodiment of the polyetheretherketone resin processing aid mixing device of this utility model, the scraper and the inner wall of the mixing cylinder are in contact, and the first stirring blade and the second stirring blade are both perforated with multiple sets of holes.

[0009] In a preferred embodiment of the polyetheretherketone resin processing aid mixing device of this utility model, a discharge valve is connected to the lower end of the mixing cylinder.

[0013] 2. In this utility model, during the stirring of the processing aids in the mixing cylinder by the first and second stirring blades, the dual-shaft motor drives the small gear to rotate. The small gear rotates in a circle around the center of the large gear, thereby causing the mixing cylinder to rotate in a circle along the center of the large gear via the rotating shaft. This causes the materials in the upper and lower layers of the mixing cylinder to convect. Combined with the stirring of the stirring blades, the combination of the two produces a more complex flow pattern, thereby enhancing the mixing effect and accelerating the mixing rate. Both the first and second stirring blades are provided with perforations, which can reduce the resistance encountered by the stirring blades during the stirring process and accelerate the stirring speed of the stirring blades.

The outer wall of the scraper rods 47 that are close to each other has multiple sets of first stirring blades 48. The lower end of the second rotating rod 46 passes through the outer wall of the first rotating rod 45 and has multiple sets of second stirring blades 49. The mixing cylinder 2 has a mounting assembly 7 on one side of its outer wall. The mounting assembly 7 includes a mounting plate 71 on one side of the outer wall of the mixing cylinder 2. A rotating shaft 73 is inserted into the upper end of the mounting plate 71. A large gear 8 is provided at the end of the rotating shaft 73 away from the mixing cylinder 2. A small gear 9 is provided at the upper end of the large gear 8. A dual-shaft motor 10 is fixedly provided at the upper end of the cylinder cover 3.

[0018] Two sets of symmetrical first screws 5 are fixedly installed at the upper end of the mixing drum 2. The upper ends of the first screws 5 movably pass through the drum cover 3. The upper ends of the first screws 5 are threaded with first nuts 6. The upper end of the first bevel gear 42 is rotatably connected to the connecting plate 41. The second bevel gear 43 meshes with the first bevel gear 42 and the third bevel gear 44 respectively. The first rotating rod 45 is rotatably inserted into the middle of the drum cover 3. The second rotating rod 46 moves from top to bottom through the third bevel gear 44 and the first rotating rod 45. The two output ends of the dual-shaft motor 10 are connected to the pinion 9 and the second bevel gear 43 respectively. The scraper 47 is in contact with the inner wall of the mixing drum 2. The first stirring blade 48 and the second stirring blade 49 are both provided with multiple sets of... The mixing cylinder 2 is perforated and connected to a discharge valve 11 at its lower end. The mounting assembly 7 also includes a mounting groove 72 on the upper end of the mounting plate 71 and which cooperates with the rotating shaft 73. The end of the rotating shaft 73 away from the large gear 8 is movably inserted into the mounting groove 72. A second screw 74 is threaded into the outer wall of the mounting plate 71. The front end of the second screw 74 moves through the mounting plate 71, the rotating shaft 73 and the mounting groove 72 in sequence. The rotating shaft 73 has an insertion hole that cooperates with the second screw 74. A second nut 75 is threaded onto the outer wall of the front end of the second screw 74. The end of the rotating shaft 73 away from the mixing cylinder 2 is rotatably connected to the middle of the outer wall of the large gear 8. The large gear 8 is fixedly connected to the upper end of the base 1. The large gear 8 and the small gear 9 mesh with each other.

[0019] First, place the processing aids to be mixed into the mixing cylinder 2 according to the mixing ratio. Then, slide the mounting plate 71 on one side of the outer wall of the mixing cylinder 2 along the rotating shaft 73 with the mounting groove 72 opened on the mounting plate 71 until the bottom end of the mounting groove 72 contacts the rotating shaft 73. At this time, insert the second screw 74 into the lower end of the mounting plate 71 and pass through the insertion hole opened in the rotating shaft 73. Then, thread the second nut 75 onto the front end of the second screw 74 to complete the fixing of the mounting plate 71. At this time, the first screw 5 set at the upper end of the mixing cylinder 2 passes through the cylinder cover 3 and the first nut 6 is threaded. Upon reaching the upper end of the first screw 5, the connection between the cylinder cover 3 and the mixing cylinder 2 is completed. The dual-shaft motor 10 is then activated, driving the pinion 9 and the second bevel gear 43 to rotate. The rotation of the second bevel gear 43 drives the first bevel gear 42 and the third bevel gear 44 to rotate. The first bevel gear 42 and the third bevel gear 44 rotate in opposite directions, thus causing the first rotating rod 45 and the second rotating rod 46 to rotate in opposite directions. The first rotating rod 45 drives the scraper 47 to rotate, which in turn drives the first stirring blade 48 to rotate. The second rotating rod 46 drives the second stirring blade 49 to rotate, and the first stirring blade 48... The first and second stirring blades 48 and 49 are arranged alternately, and the first and second stirring blades 48 rotate in opposite directions. When the two sets of stirring blades rotate in opposite directions, the material in the mixing drum will be subjected to shear forces from different directions. This helps to break up the agglomeration structure in the additives, promote the uniform dispersion of the additives, and ensure the uniformity of mixing. During the stirring of the processing additives in the mixing drum 2 by the first stirring blades 48 and 49, the dual-shaft motor 10 drives the pinion 9 to rotate. The pinion 9 rotates in a circle around the center of the large gear 8, so that the mixing drum 2 is moved by the rotating shaft 7. 3. The gear 8 rotates in a circular motion around its center, causing the materials in the upper and lower layers of the mixing cylinder 2 to convect. Combined with the stirring of the stirring blades, the two work together to create a more complex flow pattern, thereby enhancing the mixing effect and accelerating the mixing rate. Both the first stirring blade 48 and the second stirring blade 49 have perforations. The perforations can reduce the resistance encountered by the stirring blades during the stirring process and accelerate the stirring speed of the stirring blades. During the rotation of the scraper 47, the material on the inner wall of the mixing cylinder 2 can be scraped to prevent some sticky processing aids from adhering to the inner wall of the mixing cylinder 2 and causing uneven mixing.
