[0004] However, the sizes of the inlet and outlet of most raw material barrels are different from those of the barrel body. If the stirring mechanism needs to enter the raw material barrel, its size must be smaller than the size of the inlet and outlet, which is much smaller than the size of the barrel body. Therefore, the actual stirring area of ​​the stirring mechanism only occupies a part of the raw material barrel, and the polytetrafluoroethylene cannot be fully stirred. Utility Model Content

[0005] The utility model aims to provide a raw material stirring device for the production and processing of polytetrafluoroethylene to solve the problems raised by the above-mentioned background technology.

[0007] The stirring rod has at least two working states including an unfolded state and a retracted state. In the unfolded state, the stirring area of ​​the stirring rod is increased. In the retracted state, the size of the stirring rod is smaller than the size of the raw material barrel inlet.

[0008] Preferably, the lifting plate is fixedly connected to two sliding blocks, and the two sliding blocks are respectively slidably connected to two sliding grooves in the stirring frame.

[0009] Preferably, the stirring rod is provided with a lifting seat, which is slidably connected to a lifting groove in the stirring rod body, and a plurality of first stirring members are hinged on the lifting seat, which are distributed in a circular array around the center line of the lifting seat.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-Figure 5 , a raw material stirring device for the production and processing of polytetrafluoroethylene, including a stirring frame 1, an electric telescopic rod 2, and a raw material barrel 5. The raw material barrel 5 is used to store polytetrafluoroethylene. Polytetrafluoroethylene is one of the materials with the best corrosion resistance in the world today, so it is known as the "King of Plastics". It can be used for a long time in any kind of chemical medium. Polytetrafluoroethylene seals, washers, and gaskets. Polytetrafluoroethylene seals, gaskets, and sealing gaskets are made of suspended polymerized polytetrafluoroethylene resin molding. The output end of the electric telescopic rod 2 is connected to the lifting plate 3. It should be noted that the lifting plate 3 is fixedly connected to two sliders, and the two sliders are respectively slidably connected to the two slide grooves in the stirring frame 1. The slide groove and the slider are used to limit the moving direction of the lifting plate 3 to prevent it from deflecting when moving up and down. A stirring motor 4 is installed on the lifting plate 3. The output end of the stirring motor 4 is connected to the power shaft 6, and the power shaft 6 is connected to the stirring rod 7;

[0028] In a further embodiment, the size of the inlet of the raw material barrel 5 is different from that of the barrel body, the size at the inlet is smaller, and the size at the barrel body is larger. If the polytetrafluoroethylene is simply stirred using a round rod, the stirring area is small and the polytetrafluoroethylene cannot be fully stirred. Therefore, the stirring rod 7 has at least two working states including an unfolded state and a retracted state. In the unfolded state, the stirring area of ​​the stirring rod 7 increases. In the retracted state, the size of the stirring rod 7 is smaller than the size of the inlet of the raw material barrel 5 and can pass through the inlet of the raw material barrel 5. Specifically, a lifting seat 70 is provided on the stirring rod 7. 3. The lifting seat 703 is slidably connected to the lifting groove in the body of the stirring rod 7. A plurality of first stirring members 704 are hinged on the lifting seat 703. The plurality of first stirring members 704 are arranged in a circular array around the center line of the lifting seat 703. The first stirring member 704 is rotatably connected to the second stirring member 705. The other end of the second stirring member 705 is rotatably mounted on the bottom of the lifting groove. It should be noted that the depth of the lifting groove is greater than the thickness of the first stirring member 704 and the second stirring member 705. In this way, the first stirring member 704 and the second stirring member 705 can be completely retracted into the lifting groove.

[0029] The stirring rod 7 has two states. In the retracted state, it is used to pass through the entrance of the raw material barrel 5. In the unfolded state, the first stirring member 704 and the second stirring member 705 therein can be unfolded, and the stirring area of ​​the entire stirring rod 7 is larger, so that the polytetrafluoroethylene therein can be fully stirred.

[0030] More specifically, a positioning rod 706 is inserted into the lifting seat 703, and a plurality of positioning holes 707 cooperating with the positioning rod 706 are provided in the stirring rod 7; the height of the lifting seat 703 is manually adjusted, and after adjustment, it is fixed by the positioning rod 706 and the positioning hole 707;

[0031] In a further embodiment, if the stirring rod 7 connected to the stirring frame 1 is to enter the raw material barrel 5, the electric telescopic rod 2 is required to drive the stirring rod 7 to move to a height exceeding the barrel body of the raw material barrel 5. Therefore, the stroke of the electric telescopic rod 2 needs to exceed the height of the barrel body of the raw material barrel 5, and the stroke requirement of the electric telescopic rod 2 is relatively large. In order to allow the device to overcome this shortcoming, the stirring rod 7 is detachably connected to the power shaft 6. Specifically, a convex groove 601 is provided at the bottom of the power shaft 6, and the convex groove 601 is plugged with a convex part 701 in the stirring rod 7. The convex part 701 can prevent the stirring rod 7 from moving up and down after being inserted into the power shaft 6, and is more convenient for the subsequent alignment of the positioning member 602 and the mounting hole. The positioning member 602 is inserted into the power shaft 6, and the stirring rod 7 is provided with a mounting hole at a position corresponding to the positioning member 602. It should be noted that the mounting hole is set to a square shape, and accordingly, the positioning member 602 connected thereto is set to a square shape. Threaded parts are provided at both ends of the positioning member 602, and the threaded part is connected to the positioning nut 603 by threading. A handle 702 is installed at the position of the stirring rod 7 near the convex part 701;

[0032] A pressing plate 8 is fixedly mounted on the lifting plate 3. When the polytetrafluoroethylene is stirred, the pressing plate 8 is pressed on the raw material barrel 5 to compress and fix it.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
