Description
Technical Field
[0001] The invention relates to the technical field of plastic product manufacturing, and more specifically to a modified polytetrafluoroethylene granulation material processing device and method. Background Art
[0002] Although the polytetrafluoroethylene products currently on the market are resistant to high temperatures, they are difficult to adapt to working scenarios with extremely low temperatures. In order to improve the low-temperature resistance of polytetrafluoroethylene products, using modified polytetrafluoroethylene granules as raw materials is one of the effective measures.
[0003] Among them, in the production process of modified polytetrafluoroethylene granules, various powders for producing modified polytetrafluoroethylene products need to be pretreated. The prior art usually uses a processing device to mix the above-mentioned various powders together in a certain proportion to obtain the required modified polytetrafluoroethylene granules. In the actual operation process, due to the spiral winding of the polytetrafluoroethylene molecular chain, the various powders for preparing modified polytetrafluoroethylene products usually need to be loosened in an environment with a temperature below 23 degrees. If the temperature exceeds 23 degrees, the powders are easy to clump, resulting in difficulty in mixing the powders evenly. In order to avoid the above situation, producers often install the processing equipment in an environment below 23 degrees to carry out mixing work.
[0004] Although the existing processing equipment can well complete the processing of modified polytetrafluoroethylene granules under low temperature environment, in the actual operation process, the stirring shaft and stirring blades inside the processing equipment will inevitably rub against the powder during rapid stirring, resulting in the temperature of the stirring shaft and stirring blades rising, and the part of the powder in contact with them is easy to clump and difficult to mix evenly, which has certain shortcomings.

[0017] Preferably, the processing method comprises the following steps:
[0018] S1: First, polytetrafluoroethylene suspension resin, copper powder, carbon fiber, polyimide, and graphite are poured into the corresponding stirring tank according to a preset ratio, and then the stirring tank is driven upward by the first moving part until the plurality of stirring tanks are respectively docked with the corresponding tank covers;

[0024] The present invention adopts the technical means of tilting the heat dissipation fins so that the rotating heat dissipation fins have a heat dissipation effect similar to that of a heat dissipation fan, blowing cold air to the stirring tank and the stirring shaft to further cool them, and at the same time can also blow away the dust attached to the tank body, achieving a cleaning effect, thereby further improving the practicality of the device.

The fourth movable part drives the extrusion rod to reciprocate in the vertical direction, so that the convex part at the upper end of the extrusion rod intermittently hits the convex part on the supporting plate. The impact force is utilized to make the powder in the mixing tank looser and thus stir it more evenly. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] In a specific embodiment, each heat dissipation fin 406 is in the shape of an inclined fan blade.
[0066] The working principle and beneficial effects of the above technical solution are as follows: by setting the heat dissipation fins 406 to be inclined fan blades, the heat dissipation fins 406 rotate to blow cold air toward the stirring tank 501 and the stirring shaft 404 to further cool them down. At the same time, the dust attached to the tank body can also be blown away, thereby achieving a cleaning effect and further improving the practicality of the device.
[0067] Working principle:
[0068] First, the powders of raw materials such as polytetrafluoroethylene suspension resin, copper powder, carbon fiber, polyimide, graphite, etc. are poured into the corresponding stirring tank 501 according to the pre-mixed proportions, and then the stirring tank 501 is driven to move upward by the first moving part 600, and the threaded rod 602 is rotated to make the threaded rod 602 move upward relative to the mounting frame 601, and the upper end of the threaded rod 602 pushes the corresponding stirring tank 501, so that the limiting bar 603 and the corresponding limiting groove on the stirring tank 501 slide relative to each other, and at the same time, the stirring tank 501 is restricted in its moving trajectory by the limiting bar 603, and moves vertically upward under the push of the threaded rod 602 until multiple stirring tanks 501 are respectively docked with the corresponding tank covers 403, and then multiple fastening bolts 502 are tightened to fasten the stirring tank 501 and the tank cover 403.
[0069] Next, the speed regulating motor 701 is started, and the output shaft of the speed regulating motor 701 rotates, driving the rotating shaft 702 to rotate. The rotating shaft 702 drives the supporting platform 200 and the multiple stirring tanks 501 thereon to rotate synchronously. The rotation accelerates the air flow rate near the stirring tank 501 and reduces the temperature of the stirring tank 501. The stirring tank 501 drives the tank cover 403 to rotate together, so that the second gear 803 on the stirring shaft 404 rotates relative to the first gear 802, thereby driving the multiple stirring shafts 404 to rotate. The multiple stirring blades 405 on the stirring shaft 404 rotate synchronously to mix the multiple raw materials in the stirring tank 501 together.
[0070] Since the stirring shaft 404 and the stirring blades 405 have good thermal conductivity, most of the heat generated by stirring is transferred to the heat dissipation fins 406 on the top of the stirring shaft 404. The rotating heat dissipation fins 406 quickly dissipate the heat into the air, so that the stirring shaft 404 and the stirring blades 405 are always maintained at a low temperature. At the same time, since the heat dissipation fins 406 are inclined, they blow cold air toward the stirring tank 501 when they rotate, further reducing the temperature of the stirring tank 501 and the powder inside.
[0071] The rotation of the rotating shaft 702 drives the large tension wheel 903 to rotate synchronously. The large tension wheel 903 drives the small tension wheel 904 to rotate through the tension belt 905, and then drives the two vertical rods 902 and the reciprocating screw 901 to rotate. The reciprocating screw 901 drives the slider 906 to move. The slider 906 is restricted by the sliding groove and can only reciprocate in the vertical direction. When the slider 906 moves upward to the inner top of the sliding groove, the convex part on the extrusion rod 907 moves to the protrusion 909. The reaction force generated by the collision causes the powder in the mixing tank 501 to shake relative to the tank body, making the powder looser and preventing some powder from always clinging to the tank wall without being stirred due to the centrifugal force generated by the rotation. Similarly, the extrusion rod 907 and the slider 906 slide relative to each other, and the spring 908 is compressed. After the extrusion rod 907 moves away from the bump 909, the spring 908 bounces the extrusion rod 907 up to prepare for the next collision.
[0072] After the powder in the mixing tank 501 is mixed, the speed regulating motor 701 is turned off, the fastening bolt 502 is loosened, and the mixing tank 501 is driven to move downward by the first moving part 600. Finally, the pipe cover 504 is opened to pour the mixed powder out from the discharge pipe 503.
[0073] Finally, the mixed powder is introduced into the mold according to the total amount for pressing and forming, the green body is sintered to finalize the shape, the sintered green body is processed into products, and the products are tested as finished products. These steps are all existing technologies, so they will not be described in detail here.
[0074] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.

8. A processing method using the modified polytetrafluoroethylene granulation material processing device according to any one of claims 1 to 7, comprising the following steps: S1: First, polytetrafluoroethylene suspension resin, copper powder, carbon fiber, polyimide, and graphite are poured into the corresponding stirring tank (501) according to a preset ratio, and then the stirring tank (501) is driven to move upward by the first moving part (600) until the plurality of stirring tanks (501) are respectively docked with the corresponding tank covers (403); S2: Next, the second moving part (700) drives the supporting platform (200) to rotate, thereby driving the supporting platform (200) to drive the multiple stirring tanks (501) thereon to rotate synchronously, thereby driving the tank cover (403) to rotate together, so that the second gear (803) on the stirring shaft (404) rotates relative to the first gear (802), thereby driving the multiple stirring shafts (404) to rotate, and the multiple stirring blades (405) on the stirring shaft (404) to rotate synchronously, so that the multiple raw materials in the stirring tank (501) are mixed together; S3: Most of the heat generated by stirring is transferred to the heat dissipation fins (406) on the top of the stirring shaft (404). The rotating heat dissipation fins (406) quickly dissipate the heat into the air, so that the stirring shaft (404) and the stirring blades (405) are always kept at a relatively low temperature. At the same time, because the heat dissipation fins (406) are arranged at an angle, they blow cold air toward the stirring tank (501) when they rotate, further reducing the temperature of the stirring tank (501) and the powder inside. S4: The rotation of the rotating shaft (702) drives the large tension wheel (903) to rotate synchronously, thereby driving the two vertical rods (902) and the reciprocating screw (901) to rotate. The reciprocating screw (901) drives the slider (906) to move. When the slider (906) moves upward to the inner top of the slide groove, the convex part on the extrusion rod (907) moves to the rotation path of the protrusion (909) and collides with the protrusion (909). The reaction force generated by the collision causes the powder in the mixing tank (501) to shake relative to the tank body, thereby preventing part of the powder from always clinging to the tank wall due to the centrifugal force generated by the rotation and not being stirred. After the powder in the mixing tank (501) is mixed, the pipe cover (504) is opened and the stirred powder is poured out from the discharge pipe (503).
