DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the embodiments:

[0027] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] like Figures 1 to 7As shown, a vacuum kneading machine comprises: a base 11, a plurality of support frames 12 are arranged on the base 11 at intervals, a silo 13 capable of placing materials is connected to the plurality of support frames 12, a receiving tank 131 capable of receiving materials is arranged in the silo 13, a stirring assembly 14 capable of stirring materials in the receiving tank 131 is connected to the silo 13, a first driving assembly 2 capable of driving the stirring assembly 14 to move is further arranged on the base 11, a speed reduction assembly 3 is connected between the first driving assembly 2 and the stirring assembly 14, a mounting frame 15 is further connected to the base 11, a kettle cover 16 capable of rotating relative thereto to close or open the silo 13 is connected to the mounting frame 15, a locking structure 4 capable of locking the kettle cover 16 and the silo 13 is arranged between the kettle cover 16 and the silo 13, and a vacuum pumping assembly 5 capable of vacuuming the receiving tank 131 is further connected to the kettle cover 16.

[0029] When the present structure is adopted, the kettle cover 16 and the silo 13 are locked by the locking structure 4, thereby improving the sealing between the kettle cover 16 and the silo 13. An independent mounting frame 15 is provided on the base 11, instead of connecting the kettle cover 16 and the mounting frame 15 by a hinge. This makes it safer to turn over the kettle cover 16 when connected, and can prevent the kettle cover 16 from suddenly turning over and colliding with the side of the silo 13 under the action of gravity. At the same time, it is also convenient to open and close the kettle cover 16, making it more convenient and safer to use.

[0030] like Figure 4 As shown, the locking structure 4 includes a connecting bracket 41 connected to the kettle cover 16 and extending along the kettle cover 16 toward the silo 13, the connecting bracket 41 is connected with a rotating hook 42 that can rotate relative to it, the rotating hook 42 is provided with a supporting surface 421 that can abut against the lower edge surface 132 of the silo 13 to lock the kettle cover 16 and the silo 13, the kettle cover 16 is provided with a protruding connecting portion 161, and a first cylinder 43 that can be rotatably connected relative to the two is provided between the connecting portion 161 and the rotating hook 42, the rear end of the first cylinder 43 is rotatably connected to the connecting portion 161, and the first output shaft 431 on the first cylinder 43 is rotatably connected to the movable end of the rotating hook 42. When the first cylinder 43 is started, the first output shaft 431 of the first cylinder 43 extends outward, and the first output shaft 431 pulls the rotating hook 42 to rotate. The rotating hook 42 rotates relative to the connecting bracket 41 to separate the top support surface 421 from the lower edge surface 132. At this time, the rotating hook 42 is separated from the silo 13, and the kettle cover 16 can also rotate relative to the mounting bracket 15. The first cylinder 43 will also rotate relative to the connecting portion 161 under its own action.

[0031] like Figure 4As shown, the connecting bracket 41 includes two connecting pieces 411 arranged at intervals, and a movable space 412 for the rotating hook 42 to rotate is formed between the two connecting pieces 411. The rotating hook 42 is provided with a connecting protrusion 422 arranged transversely, and the rotating hook 42 is rotatably connected between the two connecting pieces 411 through the connecting protrusion 422. The setting of the connecting protrusion 422 facilitates the rotatable connection to the two connecting pieces 411, and the setting of the movable space 412 facilitates the rotation of the rotating hook 42.

[0032] like Figure 4 As shown, the kettle cover 16 is also provided with a vertically arranged connecting frame 162, the connecting portion 161 is arranged on the connecting frame 162, the rotating hook 42 is rotatably connected to the connecting frame 162, and the connecting frame 162 is provided with a movable groove 1621 capable of accommodating the first cylinder 43 and allowing the first cylinder 43 to move therein. When the first cylinder 43 is arranged in the middle, the first cylinder 43 cannot be placed horizontally due to the obstruction of the components on the kettle cover 16. By vertically arranging the connecting frame 162, the first cylinder 43 can be installed vertically, so that the structure of the entire locking structure 4 is more compact and occupies a smaller volume.

[0033] like Figure 1 As shown, a protruding connection block 163 is provided on the kettle cover 16 and located on one side of the mounting frame 15, and the second driving assembly 6 includes a second cylinder 61 rotatably connected to the mounting frame 15, and a rotating member 612 is connected to the second output shaft 611 of the second cylinder 61, and the rotating member 612 is rotatably connected to the connection block 163. After the second cylinder 61 is started, the second output shaft 611 of the second cylinder 61 retracts inward, and at this time, the rotating member 612 on the second output shaft 611 drives the connection block 163 to move, and when the connection block 163 moves, it pulls the kettle cover 16 to move, and the kettle cover 16 rotates relative to the mounting frame 15 to open the silo 13. When the second cylinder 61 is started again, the second output shaft 611 of the second cylinder 61 extends outward. At this time, the rotating member 612 on the second output shaft 611 drives the connecting block 163 to move. When the connecting block 163 moves, it pulls the kettle cover 16 to move. The kettle cover 16 rotates in the opposite direction to the mounting frame 15 to close the silo 13.

[0034] like Figure 5 As shown, a positioning groove 133 is provided on the top surface of the silo 13, and a positioning block 164 is provided on the kettle cover 16, which protrudes outward and can be inserted into the positioning groove 133. The kettle cover 16 and the silo 13 are positioned by the positioning block 164 and the positioning groove 133, and the sealing between the silo 13 and the kettle cover 16 can also be improved.

[0035] like Figures 6 to 7As shown, the stirring assembly 14 includes a rotating shaft 141 that is transversely arranged through the silo 13 and is rotatably connected to the silo 13. The front end of the rotating shaft 141 is connected to the speed reduction assembly 3. A plurality of stirring paddles 142 are connected to the rotating shaft 141. The plurality of stirring paddles 142 are arranged at intervals along the rotating shaft 141, and the adjacent stirring paddles 142 are arranged at an angle. The adjacent stirring paddles 142 are arranged at an angle to increase the fluidity and uniformity of the material when stirring the material, reduce dead angles, and improve the stirring efficiency. The rotating shaft 141 is arranged in a square shape to facilitate the installation of the stirring paddles 142.

[0036] like Figures 6 to 7 As shown, the stirring paddle 142 includes a support bracket 1421 connected to the rotating shaft 141, and an inclined paddle plate 1422 is connected to the support bracket 1421. The paddle plate 1422 is inclined to increase the contact area and stirring force during stirring, thereby improving the stirring efficiency and promoting more uniform mixing of materials.

[0037] like Figure 3 As shown, the kettle cover 16 is provided with a connecting pipe port 165 to which the vacuum assembly 5 can be connected. The vacuum assembly 5 is connected to the kettle cover 16 through the connecting pipe port 165. After the kettle cover 16 and the silo 13 are locked, the silo 13 is vacuumed.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
