[0036] The top plate 1 is also provided with a capping mechanism and a capping mechanism corresponding to the position of the barrel cover placement groove 21 .

[0037] like Figure 5 and Figure 6As shown, the capping mechanism includes a capping rotary motor 20 installed on the lower end surface of the top plate 1, a rotary arm 17 installed on the main shaft of the capping rotary motor 20, and a capping hydraulic mechanism 19 installed on the end of the rotary arm 17; the hydraulic rod of the capping hydraulic mechanism 19 extends vertically downward, and a suction cup 14 is installed at the end of the rod, and the suction cup 14 is correspondingly installed with a vacuum pump 15 through a pipeline;

[0038] The suction cup 14 is located directly above the barrel cover placement groove 21. The suction cup 14 can move up and down under the control of the capping hydraulic mechanism 19, and can suck the barrel cover in the capping placement groove under the action of the vacuum pump 15. After sucking the barrel cover, it can be rotated and adjusted in position under the action of the capping rotating motor 20, so that the suction cup 14 is located directly above the outer barrel placement turntable 22, and the capping hydraulic mechanism 19 controls the suction cup 14 to move downward to cover the barrel cover on the barrel.

[0040] After the barrel cover is covered on the barrel, the cover pressing hydraulic mechanism 11 drives the pressing wheel 10 to move downward, and the pressing wheel 10 presses on the edge of the barrel cover. At this time, the turntable rotating motor 13 drives the barrel placement turntable 22 and the barrel to rotate, pressing and fixing the barrel cover on the barrel.

[0041] like Figure 7 As shown, the first rotating mechanism includes a first meshing gear ring 34 extending downward from the lower end of the rotating drum 4 and a first rotating motor 30, on which a first meshing gear 31 is installed. The first meshing gear 31 is installed corresponding to the first meshing gear ring 34, thereby realizing the rotation of the rotating drum 4.

[0042] The second rotating mechanism includes a second meshing gear ring 26 which is arranged at the outer end of the annular plate 6 and extends downward, and a second rotating motor 32, on which a second meshing gear 33 is mounted. The second meshing gear 33 is mounted corresponding to the second meshing gear ring 26, thereby realizing the rotation of the annular plate 6.

[0043] The limiting structure includes an annular slider 25 installed on the lower end surface of the annular plate 6 and a fixed annular slide rail 26 , and the annular slider 25 is embedded in the annular slide rail 26 .

[0044] The fixed baffle 28 is also provided with a through hole 29 which is adapted to the position and size of the barrel cover placement groove 21. A lifting mechanism 8 is installed below the through hole 29. A support plate 9 is installed on the main shaft of the lifting mechanism 8. The support plate 9 extends from the through hole 29 into the barrel cover placement groove 21 to lift the barrel cover in the barrel cover placement groove 21 accordingly.

[0045] The barrel placement turntable 22 is also provided with positioning grooves 16 , and the barrels are placed in the positioning grooves 16 accordingly.

[0046] A positioning frame 18 corresponding to the position of the barrel placement turntable 22 is also provided on the annular plate 6 . The positioning frame 18 is configured as a semicircular fence structure and surrounds the outer side of the barrel placement turntable 22 .

[0047] The specific working principle and process of the present invention are as follows: when the device is used, the material barrel needs to be placed on the material barrel placing turntable first. The material barrel placing turntable is provided with a positioning groove, and the material barrel can be directly placed in the positioning groove. Then, the second rotating motor is turned on, and the second meshing gear on the second rotating motor drives the second meshing gear ring on the annular plate of the outer ring to rotate, thereby driving the annular plate to rotate and moving the material barrel to the bottom of the injection port.

[0048] At this time, the suction pump is turned on to suck the material in the silo and then input it into the filling port through the suction pipe, and then poured downward from the filling port into the barrel to complete the filling of the barrel. After that, the annular plate is continued to be rotated by the second rotating mechanism to move the filled barrel to the position corresponding to the capping mechanism and the pressing mechanism.

[0049] First, the barrel is capped through the capping mechanism. After the capping rotating motor is turned on, it drives the rotary arm to rotate, and moves the capping hydraulic mechanism and the suction cup to the top of the barrel cover placement slot. There are many stacked barrel covers placed in each barrel cover placement slot. Then, the suction cup is driven downward by the capping hydraulic mechanism. The suction cup generates suction under the action of the vacuum pump, thereby sucking the suction cup. Then, the capping rotating mechanism drives the rotary arm to rotate to the top of the barrel, and then the suction cup is driven downward by the capping hydraulic mechanism to place the barrel cover on the barrel to complete the capping process. However, at this time, the barrel cover is only covered on the barrel and is not pressed tightly, so it is necessary to press the barrel cover tightly.

[0050] After the barrel cover is covered on the barrel, the cover hydraulic mechanism controls the pressure wheel to press down and press on the edge of the barrel, and at this time, the turntable rotation motor is controlled to start to drive the barrel placement turntable to rotate. After the barrel placement turntable rotates, it drives the barrel to rotate as well, and the pressure wheel pressed on the barrel cover above rotates accordingly. After one rotation, the barrel cover is pressed tightly on the barrel, and when the barrel placement turntable rotates, since the pressure wheel above is pressed on the edge of the barrel cover, there is a risk of the barrel tipping over. In order to prevent the barrel from tipping over or the position being not stable enough, the present invention also provides a corresponding positioning frame on the annular plate, and the positioning frame is a fence-type structure and is semicircular. When the barrel rotates accordingly, the barrel will not tip over due to the protection of the positioning frame on the outside, and the barrel as a whole is very convenient to take and put.

[0051] In the process of the capping mechanism sucking the barrel cover from the barrel cover placement groove through the suction cup, a through hole is also provided on the fixed baffle plate, and a supporting plate extends from the through hole into the barrel cover placement groove to lift the barrel cover. When the barrel cover is sucked, the lifting mechanism drives the supporting plate to move up, so that the barrel cover moves up, ensuring that the suction cup can suck the barrel cover. When the barrel cover in the barrel cover placement groove is used up, the second rotating mechanism drives the rotating drum to rotate, and moves the other barrel cover placement groove to the corresponding position of the capping mechanism, ensuring smooth operation.

[0052] The above specific implementation is only a preferred embodiment of the present invention and is not intended to limit the implementation of the present invention and the scope of the claims. All equivalent changes and modifications made according to the content of the patent protection scope of the present invention should be included in the scope of the patent application of the present invention.
