In view of this, a stirring device for an environmentally friendly plasticizer is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a stirring device for an environmentally friendly plasticizer.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an environmentally friendly plasticizer stirring device, comprising a processing cylinder, a guide hopper is fixed on one side of the top end of the processing cylinder, and a lower hopper is connected to the bottom end of the processing cylinder, and a processing mechanism is arranged inside the processing cylinder;

[0007] The processing mechanism includes a motor, which is embedded in the center position of the top of the processing cylinder, and the power output end of the motor is connected to a driving rod, a bidirectional threaded rod is fixed to one side of the outer wall of the driving rod, and a sliding plate is slidably connected to the outside of the bidirectional threaded rod, a worm gear is fixed above the bidirectional threaded rod on the outer wall of the driving rod, and a worm is connected to one side of the worm gear, and a crushing knife is fixed on the outer wall of the worm corresponding to the position of the guide hopper, the material enters the processing cylinder through the guide hopper, and after final mixing, stirring and crushing, it flows out through the lower hopper, and the lower hopper is provided with an electromagnetic valve for opening and closing.

[0024] Reference Figure 1-5The utility model provides a stirring device for an environmentally friendly plasticizer: it includes a processing cylinder 1, a guide hopper 2 is fixed on one side of the top of the processing cylinder 1, a lower hopper 3 is connected to the bottom of the processing cylinder 1, and a processing mechanism 4 is arranged inside the processing cylinder 1; the processing mechanism 4 includes a motor 401, the motor 401 is embedded in the center position of the top of the processing cylinder 1, a driving rod 402 is connected to the power output end of the motor 401, a bidirectional threaded rod 403 is fixed to one side of the outer wall of the driving rod 402, and a sliding plate 404 is slidably connected to the outside of the bidirectional threaded rod 403, a worm gear 405 is fixed above the bidirectional threaded rod 403 on the outer wall of the driving rod 402, a worm 406 is connected to one side of the worm gear 405, and a crushing knife 407 is fixed on the outer wall of the worm 406 at a position corresponding to the guide hopper 2, and the worm 406 is driven by the worm gear 405 to rotate the crushing knife 407 to break and cut the raw materials entering through the guide hopper 2 to avoid the appearance of overly large raw materials.

[0025] As a further implementation scheme of the above technical scheme: the sliding plate 404 is threadedly connected to the bidirectional threaded rod 403, and the sliding plate 404 forms a sliding structure with the processing barrel 1 through the bidirectional threaded rod 403. The sliding plate 404 is hollow and can stir the incoming material to avoid accumulation and incomplete mixing.

[0026] As a further implementation scheme of the above technical scheme: a filter bucket 5 is fixed below the sliding plate 404 inside the processing cylinder 1, and the bottom end of the filter bucket 5 is connected to a conveying cylinder 6, and larger raw materials are filtered out through the filter bucket 5 to avoid affecting the later fusion.

[0027] In specific implementation, when the raw materials enter the processing cylinder 1 through the guide hopper 2, the driving rod 402 is driven by the motor 401, so that the bidirectional threaded rod 403 drives the two sliding plates 404 to slide relative to or opposite to each other, and stirs the incoming raw materials to maintain uniformity. At the same time, the driving rod 402 drives the worm gear 405 to allow the worm 406 to drive the crushing knife 407 to rotate. The crushing knife 407 corresponds to the guide hopper 2 to break and cut the incoming raw materials to avoid the appearance of excessive raw materials. Finally, the materials fall into the filter bucket 5 for filtration again and then enter the conveying cylinder 6.

[0028] As a further implementation scheme of the above technical scheme: a stirring mechanism 7 is arranged inside the conveying cylinder 6, and the stirring mechanism 7 includes a connecting plate 701, and the connecting plate 701 is rotatably connected to the top end of the filter bucket 5, and the axial bottom end of the connecting plate 701 is rotatably connected to a pressing roller 702, and a scraper 703 is fixed to the other axial outer wall of the connecting plate 701. The scraper 703 is driven by the connecting plate 701 to slide along the filter bucket 5, and the filtered raw materials are cut and crushed until they meet a uniform particle size and enter the conveying cylinder 6.

[0029] As a further implementation scheme of the above technical scheme: the stirring mechanism 7 also includes a stirring blade 704, which is fixed to the outer wall of one end of the driving rod 402 that penetrates into the conveying cylinder 6, and a filter cylinder 705 is fixed to the bottom end of the driving rod 402, and a blocking block 706 is connected to the bottom of the filter cylinder 705. The raw materials entering the conveying cylinder 6 are again stirred by the stirring blade 704 and broken at the same time, thereby further improving the degree of crushing and mixing of the raw materials.

[0030] As a further implementation scheme of the above technical scheme: the pressing roller 702 fits tightly with the filter bucket 5, and the pressing roller 702 forms a rotating structure with the filter bucket 5 through the connecting plate 701. The filter bucket 5 is in a shape of being larger at the top and smaller at the bottom to facilitate the flow of materials.

[0032] In specific implementation, when the larger raw materials are filtered out of the filter bucket 5, the connecting plate 701, driven by the driving rod 402, allows the scraper 703 to cut and break these raw materials until they can flow, and cooperates with the pressing roller 702 to press to avoid clogging. The raw materials entering the conveying cylinder 6 are stirred and broken again by the stirring knife 704 to improve the crushing and mixing effect. The filter cylinder 705 is driven by the driving rod 402 to rotate along the conveying cylinder 6, so that the materials produce centrifugal motion, and are filtered while mixing. Finally, the non-compliant materials are accumulated inside the filter cylinder 705 and collected and cleaned by the disassembly and assembly of the blocking block 706. Finally, it should be noted that the above is only a preferred embodiment of the utility model, and is not used to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the above embodiments, or to replace some of the technical features therein by equivalents.
