Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a raw material mixing device for the production of PEEK products. Background Technology

[0002] PEEK is a linear aromatic polymer compound with repeating units in its main molecular chain. Its constituent unit is oxy-p-phenylene-oxy-carbonyl-p-phenylene. It is a semi-crystalline thermoplastic and a high-performance special engineering plastic with more significant advantages compared with other special engineering plastics.

[0003] When producing PEEK products, multiple raw materials need to be mixed evenly before the mixture is sent to an injection molding machine for injection molding.

[0004] Existing mixing devices simply rely on the downward flow of the raw materials by their own weight for discharge after mixing. However, this gravity-flow discharge is prone to low discharge efficiency due to the mutual compression of the raw materials, and the mixing effect of the raw materials is not good. Utility Model Content

[0005] In order to solve the problems of low discharge efficiency and poor mixing effect of existing mixing devices, this utility model proposes a raw material mixing device for PEEK product production.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a raw material mixing device for PEEK product production, including a mixing tank, a tank cover fixed at the upper port of the mixing tank, and a discharge cylinder fixed at the lower end of the mixing tank. A stirring motor is fixed on the upper side of the tank cover, and a feed pipe is fixed on one side of the stirring motor. A transmission rod is provided inside the mixing tank and is fixedly connected to the output shaft of the stirring motor. A spiral blade rod extending into the discharge cylinder is fixed at the lower end of the transmission rod, and a stirring frame for stirring the raw materials is fixed on the transmission rod.

[0007] As a preferred embodiment, the stirring rack includes a rotating disk, which is fixedly mounted on a transmission rod, and a plurality of uniformly arranged stirring rods are fixed on the lower surface of the rotating disk.

[0008] As a preferred embodiment, a mounting sleeve is fixed at the center of the rotating disk, and multiple locking screws are installed on the outer thread of the mounting sleeve.

[0009] As a preferred embodiment, a retaining ring is fixed to the upper end of the stirring rod, and a threaded head is fixed to the upper side of the retaining ring.

[0010] As a preferred embodiment, the upper end of the discharge cylinder is fixed with a retaining ring inserted into the inner side of the lower end of the mixing tank, and a mounting plate is fixed near the retaining ring on the discharge cylinder. A discharge pipe that can be opened and closed is fixed on the right side of the discharge cylinder near the lower end.

[0011] As a preferred option, a sealing plate is installed on the side of the discharge pipe, and a folded edge is fixed on one side of the sealing plate.

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

[0013] The stirring motor drives the transmission rod to rotate the spiral blade rod, which continuously pushes the raw materials upward. The rising raw materials fall to the sides and are mixed with the stirring frame, resulting in higher mixing efficiency and more uniform and thorough mixing, with better mixing effect.

[0014] During discharge, the reverse rotation of the stirring motor causes the spiral blade rod to reverse, which in turn propels the raw material downwards through the discharge cylinder, thereby greatly improving the discharge efficiency. Attached Figure Description

[0021] like Figure 1 and Figure 2As shown, a raw material mixing device for PEEK product manufacturing includes a mixing tank 1. A tank cover 2 is fixed at the upper end of the mixing tank 1, and a discharge cylinder 5 is fixed at the lower end of the mixing tank 1. A stirring motor 3 is fixed on the upper side of the tank cover 2, and a feed pipe 4 is fixed on one side of the stirring motor 3. A transmission rod 6 is provided inside the mixing tank 1 and is fixedly connected to the output shaft of the stirring motor 3. A spiral blade rod 8 extending into the discharge cylinder 5 is fixed at the lower end of the transmission rod 6, and a stirring frame 7 for stirring the raw materials is fixed on the transmission rod 6. The stirring motor 3 drives the transmission rod 6 to rotate the spiral blade rod 8, thereby continuously pushing the raw materials upward. The rising raw materials fall to the sides and are mixed with the stirring frame 7. During discharge, the reverse rotation of the stirring motor 3 causes the spiral blade rod 8 to reverse, thereby pushing the raw materials downward and discharging them through the discharge cylinder 5.

[0022] like Figure 3 As shown, the mixing rack 7 includes a rotating disk 72, which is fixedly mounted on the transmission rod 6. A plurality of uniformly arranged stirring rods 71 ​​are fixed on the lower surface of the rotating disk 72. The transmission rod 6 drives the rotating disk 72 to rotate, and the rotating disk 72 drives the stirring rods 71 ​​to uniformly mix the raw materials over a large area, thereby greatly improving the mixing efficiency and mixing effect.

[0023] A mounting sleeve 73 is fixed at the center of the rotating disk 72. Multiple locking screws 74 are installed on the outer thread of the mounting sleeve 73. The rotating disk 72 is mounted on the transmission rod 6 using the mounting sleeve 73 and locked in place by the locking screws 74.

[0024] like Figure 4 As shown, a retaining ring 711 is fixed to the upper end of the stirring rod 71, and a threaded head 712 is fixed to the upper side of the retaining ring 711. The stirring rod 71 is fixed to the rotating disk 72 by the threaded head 712 and is limited by the retaining ring 711 after installation and fixation.

[0025] like Figure 5 As shown, the upper end of the discharge cylinder 5 is fixed with a retaining ring 51 inserted into the inner side of the lower end of the mixing tank 1, and a mounting plate 52 is fixed near the retaining ring 51. The upper end of the discharge cylinder 5 is inserted into the lower end of the mixing tank 1 through the retaining ring 51, and is locked and fixed by the mounting plate 52 and screws.

[0026] A discharge pipe 54, which can be opened and closed, is fixed on the right side of the discharge cylinder 5 near the lower end. The discharge cylinder 5 uses the discharge pipe 54 to discharge the raw material outward, thereby realizing the discharge.

[0027] like Figure 5 As shown, a sealing plate 53 is installed on the side of the discharge pipe 54. The discharge pipe 54 is blocked by the installation of the sealing plate 53, thereby disconnecting the discharge.

[0028] The sealing plate 53 has a folded edge fixed on one side, which facilitates the pulling and inserting of the sealing plate 53.

[0029] In this embodiment, when mixing the raw materials, multiple raw materials are added into the mixing tank 1 through the feed pipe 4. At this time, the stirring motor 3 drives the transmission rod 6 to rotate the spiral blade rod 8, thereby continuously pushing the raw materials upward. The rising raw materials fall to the sides and are mixed with the stirring frame 7. After the mixing is completed, the sealing plate 53 at the discharge pipe 54 is pulled out. At this time, the reverse rotation of the stirring motor 3 causes the spiral blade rod 8 to reverse, thereby pushing the raw materials downward and discharging them through the discharge cylinder 5 and the discharge pipe 54.

[0030] When the mixing rack 7 is mixing, the transmission rod 6 drives the rotating disk 72 to rotate, and the rotating disk 72 drives the mixing rod 71 to mix the raw materials evenly over a large area.

[0031] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
