[0037] See also Figure 1-Figure 6 As shown, the present invention provides the following technical solutions: a cement finished product filling and warehousing device for cement production, comprising a lower hopper 1, a quantitative material guiding mechanism 2 and a sub-packaging mechanism 3 that cooperate with each other; the lower hopper 1 is used to place the finished cement to be filled, the quantitative material guiding mechanism 2 is used to quantitatively guide the finished cement in the lower hopper 1 to the sub-packaging mechanism 3, and the finished cement is filled and sub-packed in the sub-packaging mechanism 3 using packaging bags; wherein:

[0038] The packaging mechanism 3 is symmetrically provided with a packaging bag loading station a and a packaging bag filling station b, and the discharge end of the quantitative material guiding mechanism 2 corresponds to the packaging bag filling station b;

[0039] The subpackaging mechanism 3 includes a movable filling conduit 31, and the filling conduit 31 reciprocates between the packaging bag loading station a and the packaging bag filling station b;

[0040] In the packaging bag loading station a, the packaging bag is placed on the filling conduit 31 from the bottom of the filling conduit 31;

[0041] In the packaging bag filling station b, the dispensing mechanism 3 further includes a clamping assembly 32 and a lifting assembly 33;

[0042] The clamping assembly 32 includes two symmetrically arranged clamping cylinders 321, and the telescopic ends of the two clamping cylinders 321 are fixed with L-shaped clamping plates 322. The two L-shaped clamping plates 322 can be symmetrically clamped on both sides of the filling conduit 31. When the two L-shaped clamping plates 322 clamp the filling conduit 31, the bottom edge of the filling conduit 31 is engaged in the L-shaped corner of the L-shaped clamping plates 322, and the inner diameter of the filling conduit 31 is smaller than the minimum distance between the two L-shaped clamping plates 322.

[0043] The lifting assembly 33 includes two lifting cylinders 331 symmetrically arranged, and a lifting plate 332 is fixed on the top of the two lifting cylinders 331, an L-shaped clamping plate 322 is slidably installed on the top of the lifting plate 332, and a clamping cylinder 321 is fixedly installed on the top of the lifting plate 332, and the lifting assembly 33 can drive the clamping assembly 32 and the filling tube 31 to move up and down;

[0044] A sealing upper pressure ring 21 is provided on the discharge end of the quantitative material guiding mechanism 2 , and when the filling conduit 31 rises in the packaging bag filling station b, its top is in sealing contact with the sealing upper pressure ring 21 .

[0045] In the above structure, the quantitative material guiding mechanism 2 adopts a quantitative dragon feeder, and a filling head 22 is welded to the bottom of the quantitative dragon feeder, and a sealing upper pressure ring 21 is sleeved and welded on the filling head 22 .

[0046] In the above structure, the L-shaped clamping plate 322 includes a bottom plate 323 and a side plate 324 . The side plate 324 is vertically welded to the bottom plate 323 , and the side plate 324 is an arc-shaped structure adapted to the filling conduit 31 .

[0047] In the above structure, the dispensing mechanism 3 further includes a driving component 4 , and the filling conduit 31 is driven to move by the driving component 4 .

[0048] Specifically, regarding drive component 4:

[0049] The invention comprises a rotatable turntable 41, and at least two mounting holes are provided on the turntable 41 in a circular array, and a filling conduit 31 is passed through each mounting hole, and the filling conduit 31 can move up and down in the mounting hole. A limiting ring 411 is sleeved on the outer wall of the filling conduit 31, and the limiting ring 411 is located above the turntable 41, and a limiting spring 412 is welded between the limiting ring 411 and the turntable 41.

[0050] The turntable 41 further includes a mounting base 42 and a driving motor 43 fixed to the top of the mounting base 42 , and the turntable 41 is driven to rotate by the driving motor 43 .

[0051] In summary, the principle of the overall device for loading and filling packaging bags is:

[0052] 1) In the packaging bag loading station a, the packaging bag is placed on the filling conduit 31 from the bottom of the filling conduit 31.

[0053] 2) Start the driving motor 43, and (taking the example that only two filling tubes 31 are symmetrically arranged on the turntable 41) drive the turntable 41 to rotate 180 degrees, thereby moving the filling tube 31 with the packaging bag mounted thereon to the packaging bag filling station b.

[0054] 3) Stop the driving motor 43 and start the clamping cylinder 321, thereby driving the two L-shaped clamping plates 322 to approach each other and clamp on both sides of the filling conduit 31, thereby forming Figure 1-Figure 2 In the state shown, the stability of the connection between the packaging bag and the filling conduit 31 is effectively guaranteed, thereby avoiding the phenomenon of the packaging bag falling off during the filling process.

[0055] 4) Start the lifting cylinder 331 to drive the lifting plate 332 to rise, and then drive the clamping assembly 32 and the filling tube 31 to rise, until the top of the filling tube 31 is in sealing contact with the bottom of the sealing upper pressure ring 21, and then stop the lifting cylinder 331; in this state, the limit spring 412 is stretched and deformed.

[0056] 5) Start the quantitative material guiding mechanism 2 to guide the finished cement in the lower hopper 1 to the filling head 22, and fill the finished cement into the packaging bag through the filling head 22 and the filling conduit 31 to achieve closed filling, thereby effectively avoiding dust problems during filling. Among them, the quantitative material guiding mechanism 2 is used to achieve quantitative material guiding to ensure that the cement guided out at a single time can effectively meet the packaging quantity limit of the corresponding packaging bag. Specifically, regarding the quantitative limitation method of the quantitative material guiding mechanism 2, it can be limited by controlling the single start-up time of the quantitative material guiding mechanism 2. The principle is: the material guiding speed of the quantitative material guiding mechanism 2 is set unchanged, and its material guiding time is changed accordingly, so that the material guiding amount can be changed.

[0057] In the above structure, the packaging mechanism 3 also includes a supporting component 5, and the supporting component 5 includes two symmetrically arranged supporting uprights, the two lifting cylinders 331 are respectively fixed on the two supporting uprights, and the two lifting plates 332 are respectively slidably connected to the two supporting uprights.

[0058] Specific, combined Figure 3 It can be seen that the setting positions and setting dimensions of the two supporting uprights of the supporting component 5 should meet the following restrictions: Figure 3 In the figure, the two dotted circles represent the movement trajectory of the edge of the filling conduit 31 when it rotates. When two supporting plates are provided, it should be ensured that there is no mutual interference between the supporting plates and the movement trajectory of the filling conduit 31. Figure 3 In the figure, the dotted rectangle represents one of the support plates, and the setting position and size of the support plate will not affect the rotation of the filling conduit 31.

[0059] in addition

[0060] The packaging mechanism 3 is also provided with a packaging bag discharging station c, and the packaging bag discharging station c is located below the packaging bag filling station b.

[0061] Specifically, in the packaging bag discharging station c, the packaging mechanism 3 also includes a discharging conveyor belt 6, and a material holding box 7 located above the discharging conveyor belt 6; the material holding box 7 is located between the two lifting cylinders 331, and the material holding box 7 is used to receive the packaging bags that move down after the filling and discharging are completed; the discharging conveyor belt 6 is used to transfer the material holding box 7 to the bottom of the filling duct 31 after the filling duct 31 is raised, and realize the discharging and conveying of the material holding box 7 after receiving the packaging bags.

[0062] Preferably, a fixed lower magnetic plate 71 and a movable upper magnetic plate 72 are provided in the material holding box 7 , the movable upper magnetic plate 72 can move up and down in the material holding box 7 , and the fixed lower magnetic plate 71 and the movable upper magnetic plate 72 repel each other.

[0063] From the above, it can be seen that after the overall device completes the filling of the packaging bag, the principle of discharging the packaging bag is:

[0064] While performing the above filling operation, the discharge conveyor belt 6 is started to transport the material box 7 to below the filling conduit 31; during this process, since the filling conduit 31 and the packaging bag are lifted, it is ensured that the material box 7 can move smoothly.

[0065] After completing the above-mentioned filling operation, first reset the lifting cylinder 331. At this time, the filling tube 31 loses the upward push restriction, and moves downward under the rebound of the limit spring 412; during the downward movement, the filling tube 31 gradually moves away from the filling head 22, and the bottom of the packaging bag moves into the material holding box 7. Specifically, due to the repulsive effect between the fixed lower magnetic plate 71 and the movable upper magnetic plate 72, the movable upper magnetic plate 72 is close to the top of the material holding box 7, thereby ensuring that the movable upper magnetic plate 72 can form support for the bottom of the packaging bag.

[0066] As the lifting cylinder 331 is reset, the packaging bag gradually enters the material holding box 7, and based on the gravity of the finished cement in the packaging bag, the movable upper magnetic plate 72 gradually moves downward to approach the fixed lower magnetic plate 71.

[0067] When the lifting cylinder 331 is reset to the initial state, the lifting plate 332 is positioned above the material holding box 7. At this time, the clamping cylinder 321 is started to reset, thereby making the L-shaped clamping plate 322 away from the filling tube 31; at this time, based on the gravity of the finished cement in the packaging bag, the packaging bag automatically detaches from the filling tube 31 and falls into the material holding box 7; in this process, due to the repulsion between the fixed lower magnetic plate 71 and the movable upper magnetic plate 72, the automatic falling of the packaging bag is buffered, thereby effectively avoiding the problem of cement leakage when the packaging bag is unloaded.

[0068] Finally, the discharging conveyor belt 6 is started to discharge the material containing box 7 containing the packaging bags, so as to facilitate the subsequent packaging operation of the packaging bags.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
