Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] The present utility model provides a technical solution: As Figures 1 to 5 shown, in this embodiment, an intermittent blanking type stirring reaction device for preparing polystyrene masterbatch includes a stirring barrel 1. The top of the stirring barrel 1 is fixedly installed with a top cover 2 through bolts. The top end of the stirring barrel 1 is rotatably installed with a cylinder 3. The middle part of the cylinder 3 is in a vacuum state. The outer side of the cylinder 3 is equidistantly provided with discharge ports 4. The areas of several discharge ports 4 are different. Various raw materials can be transported into the interior of the cylinder 3. The stirring shaft 5 is slidably installed inside the stirring barrel 1. The outer side of the stirring shaft 5 is equidistantly and fixedly installed with first stirring blades 6. The first stirring blades 6 can be lifted and lowered to transport various raw materials into the interior of the cylinder 3. When the discharge port 4 on the outer side of the cylinder 3 rotates to the bottom end, it will drive the raw materials inside the cylinder 3 to be discharged from the discharge port 4. Since the areas of several discharge ports 4 are different, the discharge amounts of different raw materials will also be different, and different raw materials can be proportionally fed into the stirring barrel 1. In this way, intermittent blanking can be realized, and the materials inside the stirring barrel 1 can be fully stirred and mixed, improving the stirring and mixing effect. By controlling the intermittent lifting and lowering of the stirring shaft 5, the first stirring blades 6 can be driven to intermittently lift and lower, which can improve the stirring and mixing effect of the materials.

[0023] As Figures 1 to 5As shown, a feeding motor 7 is fixedly installed on the outer side of the stirring barrel 1. The output end of the feeding motor 7 is fixedly connected to one end of a cylinder 3. The top of the top cover 2 is fixedly installed with a feeding pipe 8 at equal intervals. The top of the feeding pipe 8 is fixedly installed with a feeding hopper 9. The bottom of the feeding pipe 8 is fixedly installed with a fixing ring 10. The fixing ring 10 is communicated with the feeding pipe 8. The fixing ring 10 is rotatably installed on the outer side of the cylinder 3. The bottom end of the fixing ring 10 is provided with a coincidence port 22 corresponding to the discharge port 4.

[0024] The cylinder 3 is driven to rotate by the feeding motor 7. When the discharge port 4 on the outer side of the cylinder 3 rotates to the top, the raw materials inside the feeding hopper 9 will be conveyed into the inside of the cylinder 3 through the connection of the feeding pipe 8. When the discharge port 4 on the outer side of the cylinder 3 rotates to the bottom and coincides with the coincidence port 22 at the bottom end of the fixing ring 10, the raw materials inside the cylinder 3 will be discharged from the discharge port 4.

[0025] As Figures 1 to 5 shown, partition plates 11 are fixedly installed on the middle part of the cylinder 3 at equal intervals.

[0026] The different raw materials conveyed into the inside of the cylinder 3 can be separated.

[0027] As Figures 1 to 5 shown, a stirring motor 12 is fixedly installed on the top of the top cover 2. The output end of the stirring motor 12 passes through the top cover 2 and is fixedly installed with a fixing rod 13. The bottom of the fixing rod 13 is symmetrically fixedly installed with first limit blocks 14. The inner wall of the top end of the stirring shaft 5 is symmetrically provided with limit grooves 15. The limit grooves 15 are slidably connected with the first limit blocks 14.

[0028] The fixing rod 13 is driven to rotate by the stirring motor 12. Through the relative limitation between the limit grooves 15 and the first limit blocks 14, the first stirring blades 6 and the second stirring blades 20 will be driven to rotate synchronously, realizing the stirring and mixing of the materials.

[0029] As Figures 1 to 5 shown, positioning rods 16 are symmetrically fixedly installed on the middle part of the stirring shaft 5. The inner wall of the stirring barrel 1 is fixedly installed with positioning rings 17 corresponding to the positions of the positioning rods 16. The middle part of the positioning ring 17 is symmetrically provided with positioning grooves 18. The ends of the two positioning grooves 18 are communicated with each other. The positioning grooves 18 are slidably connected with the positioning rods 16.

[0030] During the process of controlling the rotation of the stirring shaft 5, through the guiding and positioning of the positioning grooves 18 on the positioning rods 16, the stirring shaft 5 connected to the positioning rods 16 will be driven to lift synchronously, and the first stirring blades 6 can be driven to lift intermittently.

[0031] As Figures 1 to 5As shown in the figure, the bottom end of the stirring barrel 1 is rotatably installed with a rotating shaft 19 through a bearing. A second stirring blade 20 is fixedly installed on the outer side of the rotating shaft 19. The top of the rotating shaft 19 is symmetrically and fixedly installed with second limiting blocks 21, and the second limiting blocks 21 are slidably connected with the limiting grooves 15.

[0032] When the fixed rod 13 is driven to rotate by the stirring motor 12, the second stirring blade 20 will be driven to rotate synchronously through the relative limitation between the second limiting block 21 and the limiting groove 15, and the materials at the bottom end of the stirring barrel 1 can be stirred.

[0033] As Figures 1 to 5 shown in the figure, the bottom discharge port of the stirring barrel 1 is fixedly connected with the feed port of the injection molding machine through a flange.

[0034] The mixed materials can be directly transported into the injection molding machine, which is convenient for the preparation of polystyrene masterbatch.

[0035] The utility model provides an intermittent blanking type stirring reaction device for preparing polystyrene masterbatch. The specific working principle is as follows: when the device is in use, various raw materials are injected into the feed hoppers 9 at different positions. The cylinder 3 is driven to rotate by the feeding motor 7. When the discharge port 4 on the outer side of the cylinder 3 rotates to the top, the raw materials in the feed hopper 9 will be transported into the cylinder 3 through the connection of the feed pipe 8. When the discharge port 4 on the outer side of the cylinder 3 rotates to the bottom and coincides with the coincidence port 22 at the bottom end of the fixed ring 10, the raw materials in the cylinder 3 will be discharged from the discharge port 4. Since the areas of several discharge ports 4 are different, the discharge amounts of different raw materials will also be different, and different raw materials can be fed into the stirring barrel 1 in a fixed ratio. As the cylinder 3 rotates, the feeding of the raw materials will be cancelled, and so on, to realize intermittent blanking. At the same time, the first stirring blade 6 and the second stirring blade 20 are driven to rotate by the stirring motor 12, and the materials in the stirring barrel 1 can be fully stirred and mixed to improve the stirring and mixing effect; the fixed rod 13 is driven to rotate by the stirring motor 12, and the first stirring blade 6 and the second stirring blade 20 are driven to rotate synchronously through the relative limitation between the limiting groove 15 and the first limiting block 14 and between the second limiting block 21 and the limiting groove 15, so as to realize the stirring and mixing of the materials. At the same time, the stirring shaft 5 connected with the positioning rod 16 is driven to lift synchronously through the guiding and positioning of the positioning groove 18 on the positioning rod 16, and the first stirring blade 6 can be driven to lift intermittently, which can improve the stirring and mixing effect of the materials.

[0036] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
