It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0029] Example 1
[0030] A preferred embodiment of the plastic raw material mixing device provided by this utility model is, for example... Figures 1 to 6As shown: A plastic raw material mixing device includes a left fixed base 6; an electrical control box 5 fixedly connected to the upper end of one side of the left fixed base 6; a servo motor 4 fixedly connected to one side of the left fixed base 6; a right fixed base 9 disposed on the other side of the left fixed base 6; a drive motor 8 fixedly connected to the upper end of one side of the right fixed base 9; auxiliary grooves 15 opened on the upper ends of one side of the left fixed base 6 and the right fixed base 9, with auxiliary blocks 16 movably connected at equal angles inside the auxiliary grooves 15; a cover plate 7 and a mixing tank 10 fixedly connected to one side of the auxiliary block 16 respectively, and one side of the mixing tank 10 fixedly connected to the output end of the servo motor 4 via a coupling; the cover plate 7... The heating tube 14 is fixedly connected to the mixing tank 10 by bolts and nuts; the connecting hopper 3 is located at the middle position of the surface of the mixing tank 10, and the surface of the connecting hopper 3 is fixedly connected to the sealing cover 1 by a spiral; the filter exhaust 2 is assembled on one side of the top of the mixing tank 10, and the filter exhaust 2 is used to filter and discharge the gas generated by the mixing of raw materials; the rotating rod 13 is rotatably connected to one side of the cover plate 7, one end of the rotating rod 13 is fixedly connected to the output end of the drive motor 8 by a coupling, the surface of the rotating rod 13 is movably connected to the sliding sleeve 12 at equal intervals, and the surface of the sliding sleeve 12 is fixedly connected to the stirring blade 11 at equal angles.
[0031] The filtration exhaust 2 includes: a filter box 202 fixedly connected to one side of the surface of the mixing tank 10, a vacuum pump 201 fixedly connected to the top of the filter box 202, a connecting pipe 206 fixedly connected to the lower end of one side of the filter box 202, one end of the connecting pipe 206 communicating with the lower end of one side of the sealing cover 1; an installation groove 207 opened on the front of the filter box 202; rotating blocks 208 rotatably connected to both sides of the filter box 202; a sealing plate 204 movably connected to the front of the filter box 202; fixing blocks 209 fixedly connected to both sides of the front of the sealing plate 204; and activated carbon adsorption plates 203 fixedly connected at equal intervals to the back of the sealing plate 204.
[0032] It should be noted that some existing plastic raw material mixing devices still have certain shortcomings in actual use. During the mixing process, some gas is generated, which contains a certain odor and can affect product quality. Direct exhaust can also cause breathing discomfort to nearby workers, making it inconvenient for them to use.
[0033] In this embodiment, the sealing cover 1 on the connecting hopper 3 is opened, and the raw materials are added into the mixing tank 10 through the connecting hopper 3. The top cover is then tightened, and the heating tube 14 is activated to heat the inside of the mixing tank 10. Simultaneously, the servo motor 4 is activated to rotate the mixing tank 10, agitating the materials inside. The drive motor 8 is activated to rotate the rotating rod 13, causing the sliding sleeve 12 to rotate, which in turn causes the stirring blade 11 to rotate. The rotation direction of the rotating rod 13 is opposite to the rotation direction of the mixing tank 10, thus rapidly agitating the raw materials inside the mixing tank 10 and improving the mixing effect. Simultaneously, the gas generated during mixing can be pumped through the connecting pipe 206 to the solenoid valve, and the vacuum pump 201 is activated. The gas generated inside the mixing tank 10 is then transported to the filter box 202 through the connecting hopper 3 and the connecting pipe 206. At this point, the activated carbon adsorption plate 203 filters and adsorbs the odors in this gas, preventing them from escaping. Some gases are directly discharged, causing breathing discomfort to the staff. After mixing, the mixing tank 10 rotates, causing the connecting bucket 3 to face downwards. The connecting bucket 3 then smoothly discharges the raw materials inside the mixing tank 10. The servo motor 4 can be activated to make the mixing tank 10 rotate back and forth slightly, which facilitates the shaking of the sealing cover 1 to discharge materials and improve the discharge rate. At the same time, the rotating block 208 can be rotated periodically until it is completely separated from the fixed block 209. Then, the sealing plate 204 is pulled by the fixed block 209, which makes it easy to remove the activated carbon adsorption plate 203 from the filter box 202. This facilitates the replacement of the saturated activated carbon adsorption plate 203, ensuring the adsorption effect of the gas. When it is necessary to replace individual damaged stirring blades 11, the cover plate 7 and the right fixed seat 9 can be disassembled from the mixing tank 10. Then, the damaged stirring blades 11 can be slid off the surface of the rotating rod 13 for easy disassembly and replacement.
[0034] In a further preferred embodiment of the present invention, a sealing ring 205 is fixedly connected to one end of the surface of the sealing plate 204, and the area of the cross-section of the sealing ring 205 is equal to the area of the cross-section of the opening inside the mounting groove 207.
[0035] In this embodiment, the sealing ring 205 is used to improve the sealing performance between the sealing plate 204 and the mounting groove 207, thereby preventing gas leakage.
[0036] In a further preferred embodiment of the present invention, a rubber pad 210 is fixedly connected to the inner wall of the fixing block 209, and the rubber pad 210 is in the shape of a right trapezoid.
[0037] In this embodiment, a right-angled trapezoidal rubber pad 210 is used to improve the tightness of the rotational engagement between the rotating block 208 and the inner wall of the fixed block 209.
[0038] In a further preferred embodiment of the present invention, the fixing block 209 is L-shaped, and one end of the fixing block 209 is welded to the front side of the sealing plate 204 in an integrated structure.
[0039] In this embodiment, the L-shaped fixing block 209 is used so that the rotating block 208 can only be opened or closed by rotating from one side.

One end of the fixing bolt 18 and the inside of the bolt hole 19 form a threaded engagement structure.
[0042] In this embodiment, when individual stirring blades 11 are damaged and need to be replaced, the fixing bolt 18 can be rotated with tools until it is completely disengaged from the bolt hole 19, and then the sliding sleeve 12 can be pulled to slide off the surface of the rotating rod 13, making it easy to disassemble the damaged stirring blade 11. During installation, the sliding sleeve 12 is slidably fitted onto the surface of the rotating rod 13, and the slide bar 20 slides inside the slide groove 21. Then, the fixing bolt 18 is tightened into the bolt hole 19 to limit and fix the sliding sleeve 12 after sliding, thereby enabling the replacement of individual damaged stirring blades 11 and reducing unnecessary maintenance costs.
[0043] In a further preferred embodiment of the present invention, the slide bar 20 and the slide groove 21 form a sliding engagement structure, and the slide bar 20 and the slide groove 21 are convex in shape.
[0044] In this embodiment, the sliding between the convex slider 20 and the inside of the groove 21 is used to improve the firmness of the sliding sleeve 12 and the surface of the rotating rod 13.
[0045] In a further preferred embodiment of the present invention, the surface of the stirring blade 11 is inclined, and the stirring blade 11 is distributed at equal angles on the surface of the sliding sleeve 12.
[0046] In this embodiment, the inclined stirring blade 11 is used so that after the raw material comes into contact with the stirring blade 11, the raw material will be guided to separate from both sides of the stirring blade 11, thereby improving the mixing effect of the raw material.
[0047] In a further preferred embodiment of the present invention, a sliding sleeve 12 and a rotating rod 13 are provided with a sliding sleeve structure, and the sliding sleeve 12 is cylindrical in shape.
[0048] In this embodiment, the sliding sleeve 12 and the rotating rod 13 are slidably fitted together to facilitate smooth assembly and disassembly of the sliding sleeve 12.
[0049] In a further preferred embodiment of the present invention, a scraper 17 is fixedly connected to one end of the surface of the rotating rod 13, and the scraper 17 is L-shaped.
[0050] In this embodiment, an L-shaped scraper 17 is used to facilitate scraping the inner wall of the mixing tank 10, thereby reducing the adhesion and residue of raw materials on the inner wall of the mixing tank 10.
[0051] In a further preferred embodiment of the present invention, a sliding structure is formed between the interior of the auxiliary block 16 and the auxiliary groove 15, and the auxiliary block 16 is arc-shaped.
[0052] In this embodiment, the smoothness of the cover plate 7 and the mixing tank 10 during rotation is improved by utilizing the sliding of the arc-shaped auxiliary block 16 and the inside of the auxiliary groove 15.
[0053] In summary, the exhaust filter 2 can filter and adsorb the gas generated during the mixing of raw materials, preventing this gas from affecting product quality or causing breathing discomfort to workers. It can also replace individual damaged stirring blades 11, reducing unnecessary maintenance costs.
