Specific implementation

[0034] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model.

[0035] The utility model provides a kind of paste filling machine, and its implementation example is as follows Figures 1 to 5As shown, the assembly includes a mixing and propulsion mechanism 10, a hopper 20, a distribution valve 30, a metering mechanism 40, a conveyor belt 50, and a pneumatic mechanism 60. The mixing and propulsion structure of the mixing and propulsion mechanism 10 is located inside the hopper 20. The mixing and propulsion mechanism 10 includes a motor 11 and a mixing blade 12. The motor 11 drives the mixing blade 12 to rotate within the hopper 20, thereby achieving the functions of material mixing and material pushing. The discharge port 21 of the hopper 20 is connected to the inlet port 31 of the distribution valve 30. The distribution valve 30 has two extraction ports. The hopper 20 has two filling ports 32 and two extraction ports 33, which are respectively connected to two metering mechanisms 40. The distribution valve 30 is used to control the two metering mechanisms 40 to be connected to the feed port 31 or to control the two metering mechanisms 40 to be connected to the two filling ports 33. The metering mechanism 40 is used to extract material from the hopper 20 and to send the extracted material to the filling port 33 for output. The conveyor belt 50 is located below the filling port 33. The pneumatic mechanism 60 is used to control the operation of the distribution valve 30 and the metering mechanism 40.

[0036] When the material is placed into the silo 20, the stirring and propulsion mechanism 10 will stir the material in the silo 20 and push the material to the distribution valve 30. If the distribution valve 30 controls the two metering mechanisms 40 to be connected to the feed port 31, the two metering mechanisms 40 can obtain and store a certain amount of material. Then, after the distribution valve 30 controls the two metering mechanisms 40 to be connected to the two filling ports 33, the two metering mechanisms 40 can send the obtained and stored material to the filling port 33 for output, thereby filling the material into the receiving container 51 on the conveyor belt 50, thus completing the filling operation.

[0037] like Figures 1 to 3 As shown, this embodiment provides a distribution valve 30 including a valve housing 34 and a valve core 35. The valve housing 34 has a circular cavity 341 inside, and the rotatable valve core 35 is installed in the circular cavity 341. The circular cavity 341 is connected to the feed inlet 31, two extraction ports 32, and two filling ports 33. The outer peripheral wall of the valve core 35 is in close contact with the inner peripheral wall of the circular cavity 341. The valve core 35 has two guiding parts 351, which are separated from the inner peripheral wall of the circular cavity 341. The two guiding parts 351 are used to control the two metering mechanisms 40 to be connected to the feed inlet 31 or to control the two metering mechanisms 40 to be connected to the two filling ports 33.

[0038] With this configuration, by controlling the rotation of the valve core 35, various conduction states of the distribution valve 30 can be switched; for example, controlling the valve core 35 to rotate to... Figure 2 In the indicated state, valve core 35 blocks the two filling ports 33 and connects the two metering mechanisms 40 to the feed port 31, allowing the metering mechanisms 40 to extract material through the feed port 31; and when the control valve core 35 rotates to Figure 3In the state shown, the communication between the two metering mechanisms 40 and the feed inlet 31 will be cut off, and the communication between the two metering mechanisms 40 and the two filling charging inlets 33 will be opened, so as to facilitate the metering mechanisms 40 to send the extracted storage material to the two filling charging inlets 33 for output.

[0039] In order to enable the rotation of the valve core 35 to realize the above functions, as shown in the embodiment, the feed inlet 31 is arranged above the circular cavity 341, the two extraction inlets 32 are arranged on the opposite sides of the circular cavity 341 in the horizontal direction, and the two filling charging inlets 33 are arranged below the circular cavity 341. Figures 1 to 3 The outer peripheral wall of the valve core 35 is provided with a long arc surface 352 and a short arc surface 353 on the opposite sides, respectively, and the long arc surface 352 and the short arc surface 353 are provided with a guide part 351 between the two sides of the long arc surface 352 and the two sides of the short arc surface 353, respectively.

[0040] After adopting the arrangement, the long arc surface 352 and the short arc surface 353 can realize surface fitting abutment with the inner wall surface of the circular cavity 341, so that when the long arc surface 352 is arranged at the position shown in the figure, the long arc surface 352 can block the two filling charging inlets 33, and when the long arc surface 352 is arranged at the position shown in the figure, the long arc surface 352 can block the feed inlet 31, thereby realizing the opening and closing control function of the flow distribution valve 30 on the feed inlet 31 and the filling charging inlet 33. Figure 2 Figure 3

[0041] After arranging the guide part 351 between the two sides of the long arc surface 352 and the two sides of the short arc surface 353, and arranging the guide part 351 as a plane structure, once the valve core 35 is rotated to the state shown in the figure, not only the short arc surface 353 cannot block the feed inlet 31, but also the guide part 351 and the inner wall of the circular cavity 341 will form a gap, so that the metering mechanism 40 can extract the material through the feed inlet 31. Figure 2

[0042] Similarly, once the valve core 35 is rotated to the state shown in the figure, not only the short arc surface 353 cannot block the filling charging inlet 33, but also the guide part 351 and the inner wall of the circular cavity 341 will form a gap, so that the metering mechanism 40 can push and output the material through the filling charging inlet 33. Figure 3 As shown in the figure, the embodiment is arranged that the metering mechanism 40 comprises a metering driving cylinder 41, a universal joint 42, and a metering cylinder 43, the connecting rod of the metering driving cylinder 41 is connected with the connecting rod of the metering cylinder 43 through the universal joint 42, and the metering cavity of the metering cylinder 43 is communicated with the extraction inlet 32.

[0043] Figure 1

[0044] ​​​​​After the setting mode is adopted, once the metering driving cylinder 41 controls its connecting rod to move inward, the connecting rod of the metering cylinder 43 will be driven to move inward through the universal joint 42, so that the metering cylinder 43 becomes the state of extracting the material; and once the metering driving cylinder 41 controls its connecting rod to move outward, the connecting rod of the metering cylinder 43 will be driven to move outward through the universal joint 42, so that the metering cylinder 43 becomes the state of pushing the material.

[0045] It should be pointed out that the metering mechanism 40 of the embodiment is driven and controlled by the pneumatic mechanism 60, and the setting mode of the pneumatic mechanism 60 has various choices, and as shown in Figure 5 , the pneumatic mechanism 60 of the embodiment includes a gas pump 61, an unloading valve 62 and a two-position four-way electromagnetic reversing valve 63; the gas pump 61 is connected with the two metering driving cylinders 41 through the two-position four-way electromagnetic reversing valve 63; the unloading valve 62 is connected on the passage of the gas pump 61 and the two-position four-way electromagnetic reversing valve 63; and the two-position four-way electromagnetic reversing valve 63 is used for controlling the two metering driving cylinders 41 to be synchronously charged and discharged.

[0046] Specifically, as shown in Figure 1 and Figure 5 , the pneumatic mechanism 60 of the embodiment further includes a swing gas motor 64, the swing gas motor 64 is connected with the gas pump 61 through the two-position four-way electromagnetic reversing valve 63, and the swing gas motor 64 is used for driving the valve core 35 to rotate clockwise and counterclockwise,

[0047] Specifically, as shown in Figure 5 , the pneumatic mechanism 60 of the embodiment further includes a two-position three-way pneumatic reversing valve 65, a two-position four-way pneumatic reversing valve 66 and a one-way throttling valve 67; the two-position four-way electromagnetic reversing valve 63 is connected with the two metering driving cylinders 41 through an output port of the two-position three-way pneumatic reversing valve 65, the two-position four-way pneumatic reversing valve 66 in sequence; the two-position four-way electromagnetic reversing valve 63 is also connected with the swing gas motor 64 through another output port of the two-position three-way pneumatic reversing valve 65, and the output port of the two-position three-way pneumatic reversing valve 65 is also connected with the two-position four-way pneumatic reversing valve 66 through the one-way throttling valve 67.

[0048] Specifically, as shown in Figure 5 , the embodiment is provided with an adjustable throttling valve 68 on the passage through which the two metering driving cylinders 41 and the two-position four-way pneumatic reversing valve 66 are connected.

[0049] Specifically, as shown in Figure 5 , the embodiment is provided with an overflow valve 69 on the passage through which the two-position three-way pneumatic reversing valve 65 and the two-position four-way pneumatic reversing valve 66 are connected.

[0050] After adopting the above configuration, when the two-position four-way solenoid directional valve 63 enters working state one, the swing air motor 64 will rotate counterclockwise from 0° to 180°, thereby driving the valve core 35 to rotate to... Figure 2 The state shown allows the two metering mechanisms 40 to draw material through the feed inlet 31; if the two-position four-way solenoid directional valve 63 is controlled to enter working state two, the swing air motor 64 will rotate 180° clockwise, thereby driving the valve core 35 to rotate to Figure 3 The state shown allows the two metering mechanisms 40 to dispense material.

[0051] like Figure 1 and Figure 4 As shown, in this embodiment, two filling ports 33 are arranged side by side facing downwards; the conveyor belt 50 is used to transport two rows of receiving containers 51 to the area below the two filling ports 33 for filling.

[0052] With this setup, the conveyor belt 50 will have sufficient width to synchronously transport the two rows of receiving containers 51, thereby ensuring that materials can be filled simultaneously using both filling ports 33.

[0053] Specifically, at this time Figure 4 In this context, S represents the conveying step distance of the receiving container 51, 2a represents the bandwidth of the conveyor belt 50, V represents the conveying speed of the conveyor belt, and L represents the distance between the centers of the openings of the two receiving containers 51.

[0054] The distance between the centers of the openings of the two receiving containers 51 is the same as the distance between the centers of the two filling ports 33.

[0055] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
