Specific embodiments

[0028] As Figures 1 to 6 shown, the present utility model provides a polymer material mixing and degassing device, including:

[0029] A stirring barrel 1, a first gasket 2 is fixedly installed at the top of the stirring barrel 1, the outer surface of the top of the stirring barrel 1 is movably sleeved with a sealing cover 3, and the bottom end of the sealing cover 3 is movably connected to the top end of the first gasket 2; a stirring mechanism, the stirring mechanism is arranged at the top of the sealing cover 3;

[0030] Among them, the stirring mechanism includes a driving motor 4. The bottom end of the driving motor 4 is fixedly connected to the top end of the sealing cover 3. The other end of the output shaft of the driving motor 4 is fixedly sleeved with a long shaft 5. The bottom end of the long shaft 5 penetrates through the top end of the sealing cover 3 and extends into the interior of the stirring barrel 1. The outer surface of the long shaft 5 located inside the stirring barrel 1 is fixedly sleeved with a first stirring blade 6. The outer surface of the long shaft 5 is movably sleeved with a fixing plate 7. The top end of the fixing plate 7 is fixedly installed with a vertical rod 8. The top end of the vertical rod 8 is fixedly connected to the top end inside the sealing cover 3. The top end of the fixing plate 7 is movably connected with a driving gear 9. The inside of the driving gear 9 is fixedly sleeved with the outer surface of the long shaft 5. The outer surface of the driving gear 9 is meshed with a driven gear 10. The bottom end of the driven gear 10 is movably connected to the top end of the fixing plate 7. The inside of the driven gear 10 is fixedly sleeved with a rotating shaft 11. The bottom end of the rotating shaft 11 penetrates through the top end of the fixing plate 7 and extends into the interior of the stirring barrel 1. The outer surface of the rotating shaft 11 located inside the stirring barrel 1 is fixedly sleeved with a second stirring blade 12.

[0031] When the driving motor 4 operates, at this time the long shaft 5 will drive both the driving gear 9 and the five first stirring blades 6 to rotate. Since the driving gear 9 is meshed with the four driven gears 10, at this time the four driven gears 10 will rotate in the opposite direction driven by the driving gear 9. At the same time, the four driven gears 10 will drive a number of second stirring blades 12 to rotate in the opposite direction through the four rotating shafts 11. At this time, the materials located inside the stirring barrel 1 will be quickly and fully stirred and defoamed during the rotation of the five first stirring blades 6 and the opposite rotation of a number of second stirring blades 12.

[0032] Among them, the bottom end of the sealing cover 3 is fixedly installed with a second gasket 13. The bottom end of the second gasket 13 is movably connected to the top end of the stirring barrel 1.

[0033] Due to the design of the second gasket 13 and the first gasket 2, the sealing performance inside the sealing cover 3 and the stirring barrel 1 will be improved.

[0034] Among them, the inside of the top end of the sealing cover 3 is fixedly sleeved with a feed pipe 14. The outer surface of the feed pipe 14 is fixedly installed with a first valve 15.

[0035] Due to the design of the feed pipe 14, the materials can move through the feed pipe 14 into the interior of the sealing cover 3 and the stirring barrel 1. Due to the design of the first valve 15, when the first valve 15 is in the closed state, at this time the interior of the stirring barrel 1 and the sealing cover 3 will be in a closed state.

[0036] Among them, the inside of the bottom end of the stirring barrel 1 is fixedly sleeved with a discharge pipe 16. The outer surface of the discharge pipe 16 is fixedly installed with a second valve 17.

[0037] Due to the design of the discharge pipe 16, when the second valve 17 is in the open state, the materials inside the mixing barrel 1 will be discharged through the discharge pipe 16.

[0038] Among them, an air pump 18 is fixedly installed at the top end of the sealing cover 3. An air inlet 19 is fixedly installed at the bottom end of the air pump 18. The bottom end of the air inlet 19 penetrates through the top end of the sealing cover 3 and extends into the inside of the sealing cover 3. An air outlet 20 is fixedly installed on the back surface of the air pump 18.

[0039] Due to the design of the air pump 18, when the air pump 18 operates, the air inside the mixing barrel 1 and the sealing cover 3 will be sucked out through the air inlet 19 and then discharged to the outside through the air outlet 20, so that the inside of the mixing barrel 1 and the sealing cover 3 can be close to a vacuum state.

[0040] Among them, a fixing ring 21 is fixedly sleeved at the bottom end of the outer surface of the mixing barrel 1. A connecting rod 22 is fixedly installed at the bottom end of the fixing ring 21. The other end of the connecting rod 22 is fixedly installed with a base 23.

[0041] Due to the design of the fixing ring 21, the connecting rod 22 and the base 23, the whole mixing barrel 1 can be stably placed on the ground.

[0042] Among them, a hinge block 24 is fixedly installed at the bottom end of the outer surface of the sealing cover 3. A rotating rod 25 is hinged on the outer surface of the hinge block 24. A rotating plate 26 is fixedly installed at the bottom end of the rotating rod 25.

[0043] Since four hinge blocks 24 are hinged to four rotating rods 25, the four rotating rods 25 can drive the four rotating plates 26 to rotate around the four hinge blocks 24 as the axis.

[0044] Among them, a lifting ring 27 is movably sleeved on the outer surface of the mixing barrel 1. A lifting block 28 is fixedly installed on the outer surface of the lifting ring 27. The outer surface of the lifting block 28 is movably connected to the inside of the rotating plate 26.

[0045] Due to the design of the four lifting blocks 28, when the four lifting blocks 28 are respectively movably connected to the bottom ends inside the four rotating plates 26, the four lifting blocks 28 will lock the movement of the four rotating plates 26 at this time, thereby enhancing the sealing performance between the mixing barrel 1 and the sealing cover 3. Since the inside of the lifting ring 27 is movably sleeved on the outer surface of the mixing barrel 1, the lifting ring 27 can only move up and down along the outer surface of the mixing barrel 1. When the lifting ring 27 moves upward, the four lifting blocks 28 will move upward under the drive of the lifting ring 27. At this time, the four lifting blocks 28 will release the locking effect on the movement of the four rotating plates 26 during the upward movement.

[0046] Among them, an arc-shaped plate 29 is fixedly installed at the top of the outer surface of the stirring barrel 1. A power motor 30 is fixedly installed at the top of the arc-shaped plate 29. The other end of the output shaft of the power motor 30 is fixedly sleeved with a rotating shaft 31. The bottom end of the rotating shaft 31 penetrates through the top of the arc-shaped plate 29 and extends to the bottom of the arc-shaped plate 29. A lead screw 32 is fixedly installed at the bottom end of the rotating shaft 31. A lifting plate 33 is threadedly sleeved on the outer surface of the lead screw 32. The back surface of the lifting plate 33 is fixedly connected to the outer surface of the lifting ring 27.

[0047] When the power motor 30 operates, at this time the rotating shaft 31 will drive the lead screw 32 to rotate. Since the lead screw 32 is threadedly sleeved with the lifting plate 33, at this time the lifting plate 33 will move under the drive of the lead screw 32. At this time, the lifting plate 33 will drive the entire lifting ring 27 to move upward.

[0048] Among them, the bottom end of the lifting plate 33 is movably connected with a baffle plate 34. The top of the baffle plate 34 is movably connected to the bottom ends of the lifting ring 27 and the lead screw 32 respectively. The back surface of the baffle plate 34 is fixedly connected to the front surface of the stirring barrel 1.

[0049] Due to the design of the baffle plate 34, it will play a blocking role in the movement of the lifting plate 33 and the lifting ring 27.

[0050] The working principle and usage process of the present utility model:

[0051] First, the operator pours the high-molecular viscous material into the inside of the stirring barrel 1 through the feed pipe 14, and then closes the first valve 15. At this time, the inside of the stirring barrel 1 and the inside of the sealing cover 3 will be in a closed state. At this time, the operator starts the air pump 18. At this time, the air inside the stirring barrel 1 and the sealing cover 3 will be discharged to the outside of the stirring barrel 1 and the sealing cover 3 through the air inlet 19. When the inside of the stirring barrel 1 and the sealing cover 3 is close to a vacuum state, at this time the operator starts the drive motor 4. At this time, the long shaft 5 will drive the drive gear 9 and the five first stirring blades 6 to rotate simultaneously. At this time, the material inside the stirring barrel 1 will be stirred and mixed during the rotation of the five first stirring blades 6, so as to achieve the effect of defoaming the material. Since the drive gear 9 is meshed with the four driven gears 10, at this time the drive gear 9 will drive the four driven gears 10 to rotate in the opposite direction during the rotation. Immediately afterwards, the four driven gears 10 will drive a number of second stirring blades 12 to rotate in the opposite direction through the four rotating shafts 11. At this time, the material inside the stirring barrel 1 will be quickly and fully stirred during the rotation of the five first stirring blades 6 and the opposite rotation of a number of second stirring blades 12, thus realizing the function of fully stirring and quickly defoaming the high-molecular material.

[0052] When the operator needs to clean and repair the inside of the mixing barrel 1 and the sealing cover 3, the operator starts the power motor 30 at this time. Then the rotating shaft 31 will drive the lead screw 32 to rotate. Since the outer surface of the lead screw 32 is threadedly sleeved with the inside of the lifting plate 33, when the lead screw 32 rotates, it will drive the lifting plate 33 to move. At this time, the lifting plate 33 will drive the lifting ring 27 to move. Since the inside of the lifting ring 27 is movably sleeved with the outer surface of the mixing barrel 1, the lifting ring 27 can only move up and down along the outer surface of the mixing barrel 1. At this time, the lifting ring 27 will move upward under the drive of the lifting plate 33. At this time, the four lifting blocks 28 will move upward under the drive of the lifting ring 27. Subsequently, the four lifting blocks 28 will release the locking effect on the movement of the four rotating plates 26 during the upward movement. At this time, the operator drives the four rotating plates 26 and the four rotating rods 25 to rotate around the hinge block 24 in sequence. When the four rotating plates 26 as a whole rotate 90 degrees, the operator will be able to drive the sealing cover 3 as a whole to move, thus realizing the function of facilitating the disassembly and assembly between the mixing barrel 1 and the sealing cover 3.
