[0002] Definition of plastic: It is mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished product is solid. During the manufacturing process, it is a molten liquid. Therefore, it can be heated to melt, pressurized to make it flow, and cooled to solidify, forming various shapes. This large and varied group of materials is called plastic. Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical equipment, and lighting appliances.

[0003] In the processing of plastics, the plastic raw materials need to be stirred. Since solid impurities often appear in the plastic raw materials, the quality of plastic processing is reduced. When the screening structure in the prior art is used, since the plastic raw materials themselves are in a molten state, their fluid properties are low and blockage problems easily occur, thus affecting the processing. Based on this, the present invention designs a plastic raw material stirring processing equipment. Summary of the invention

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1: The present invention screens the plastic raw materials by setting up a screening and impurity removal structure, and separates the solid impurities therein, so as to avoid affecting the processing quality. At the same time, during use, when the plastic raw materials or solid impurities are blocked, the negative pressure fan works and the rotating plate rotates. On the one hand, the feed hopper is sealed to prevent the raw materials from entering, and on the other hand, the impurities attached to the windward side of the screening net are sucked out by the negative pressure wind force, thereby avoiding affecting the entry of the raw materials.

DETAILED DESCRIPTION

[0020] Reference Figure 1-5 A plastic raw material stirring processing equipment comprises a processing box 1 and an electronic control component. A stirring shaft 2 is vertically arranged in the processing box 1, and a stirring blade 3 is connected to the stirring shaft 2. A feed hopper 4 is connected to the side wall of the processing box 1, and a screening block 5 is arranged at the connection between the feed hopper 4 and the processing box 1. The screening block 5 is connected to a screening and impurity removal structure. A driving motor 9 is fixedly arranged on the top of the stirring shaft 2, and the driving motor 9 is fixedly arranged on the outer top wall of the processing box 1. A miscellaneous material box 6 is arranged below the feed hopper 4, and the miscellaneous material box 6 is fixedly arranged on the outer side wall of the processing box 1.

[0021] The screening and impurity removal structure includes a screening net 10, which is fixedly arranged on the screening block 5. An arc-shaped cover plate 11 is fixedly connected to one side of the feed hopper 4 of the screening block 5. A through hole is penetrated in the cover plate 11, and a sealing plate 12 is slidably connected to both sides of the through hole. The two sealing plates 12 seal the through hole when they are in a state of abutting each other. The two sealing plates 12 are controlled to move by the electric control component to realize the automatic opening and closing function of the feed hopper 4. Two springs 13 are fixedly connected to one side of the cover plate 11 close to the feed hopper 4. The fixed ends of the two springs 13 are fixedly arranged on the inner side of the processing box 1 On the wall, a fixing ring 14 of permanent magnet material is fixed at the connection between the screening block 5 and the processing box 1, and the fixing ring 14 is fixed to the inner wall of the processing box 1 by magnetic attraction, so that under normal conditions, the two springs 13 are in a compressed state, and the fixing ring 14 is magnetically adsorbed on the inner wall of the processing box 1, and when the screening net 10 is blocked, the feed pressure of the external raw material will push the screening block 5 to move, which will push the fixing ring 14 out of the magnetic attraction state with the processing box 1, and a discharge port is opened on the bottom wall of the feed hopper 4 near the screening block 5, the discharge port is connected to the miscellaneous material box 6, and the discharge port is sealed and rotatably connected with a rotating plate 15.

[0022] The outer wall of the stirring shaft 2 is provided with a connecting groove 19 of a square structure, and the shape and size of the connection between the stirring blade 3 and the connecting groove 19 match each other, so that the stirring blade 3 can rotate when the stirring shaft 2 rotates, and can also move vertically along the connecting groove 19. A threaded hole 18 is provided inside the stirring shaft 2, and a magnet block 16 is threadedly connected to the threaded hole 18. Under the threaded connection between the threaded hole 18 and the magnet block 16, the magnet block 16 can move in the vertical direction. The magnet block 16 and the center of rotation of the stirring blade 3 are magnetically attracted to each other, so that the vertical movement of the magnet block 16 will bring The dynamic stirring blade 3 moves in the vertical direction, so that the stirring blade 3 can stir evenly in the vertical direction. The driving motor 9 is set as a forward and reverse motor, so that the stirring blade 3 performs vertical reciprocating motion. A conductive torsion spring 17 is provided at the rotating connection between the rotating plate 15 and the discharge port, and the conductive torsion spring 17 is in a stretched state. The rotating plate 15 will rotate counterclockwise and seal the feed hopper 4 when the conductive torsion spring 17 contracts. A negative pressure fan 7 is provided in the miscellaneous material box 6, and the negative pressure fan 7 is electrically connected to the conductive torsion spring 17. When the conductive torsion spring 17 is energized and contracted, the negative pressure fan 7 starts to work.

[0023] A pressure-sensitive sensor is provided at the connection between the processing box 1 and the screening block 5. The pressure-sensitive sensor is electrically connected to the conductive torsion spring 17 through an electronic control component. The pressure-sensitive sensor is electrically connected to a storage capacitor. During normal use, since the fixing ring 14 has a magnetic attraction on the inner wall of the processing box 1, the pressure-sensitive sensor will self-charge the storage capacitor. When the screening net 10 is blocked and the external feeding pressure is applied, the fixing ring 14 leaves the inner wall of the processing box 1. On the one hand, the storage capacitor supplies power to the conductive torsion spring 17 so that the conductive torsion spring 17 is energized and bent. On the other hand, the connection between the external power supply and the negative pressure fan 7 is turned on, so that the negative pressure fan 7 works, and the blockage on the windward side of the screening net 10 is reversely absorbed. The collected impurities will enter the miscellaneous material box. A box door 8 is provided in the miscellaneous material box 6 for discharging solid impurities.

[0024] When in use, the driving motor 9 outputs rotation to rotate the stirring shaft 2. At this time, the magnet block 16 located on the inner side of the stirring shaft 2 is spirally connected with the threaded hole 18 opened on the inner side of the stirring shaft 2. Since there is no component between the threaded hole 18 and the magnet block 16 to limit the spin of the magnet block 16, the magnet block 16 will rotate and move vertically in the threaded hole 18 at the same time, and the amplitude of the vertical movement is relatively low. The advantage of this is that when the stirring shaft 2 rotates horizontally at an extremely high speed, the magnet block 16 will slowly move up in the vertical direction. In this way, under the effect of magnetic attraction with the center of rotation of the stirring blade 3, the stirring blade 3 will also slowly move up vertically, so that the stirring blade 3 can stir the vertical parts of the processing box 1, achieve the ability of uniform processing, and reduce the number of stirring blades 3 at the same time. Moreover, since the threaded hole 18 is installed inside the stirring shaft 2, the transmission parts will be less corroded and worn during actual use, thereby improving the service life of the transmission parts.

[0025] During the feeding process, the raw materials are screened through the screening net 10. Since the plastic raw materials are in a molten liquid state, the solid impurities attached to them will easily adhere to the windward side of the screening net 10. After drying, the solid impurities attached to the surface of the screening net 10 will become difficult to clean. During the use of the present invention, when the screening net 10 is greatly blocked, when its mesh is blocked, a large pressure will be generated on the screening net 10. At this time, the fixing ring 14 will be pushed out of the magnetic attraction state with the inner wall of the processing box 1, so that the pressure-sensitive sensor cannot feel the pressure. In this way, the gap between the fixing ring 14 and the inner wall of the processing box 1 can allow the remaining material in the feed hopper 4 to flow into the processing box 1 for further processing. At the same time, the rotating plate 15 rotates counterclockwise to a state of abutting against the inner top wall of the feed hopper 4. At this time, the feed hopper 4 will be sealed. In this way, under the operation of the negative pressure fan 7, a smaller space will be formed between the rotating plate 15 and the screening net 10, so that the negative pressure wind can easily adsorb and remove the impurities on the screening net 10, thereby achieving a self-cleaning effect, which is convenient and practical.
