Description

Technical Field

[0001] The present application relates to the field of filling technology, and in particular to a quantitative adjustment device for a plunger filling machine and a plunger filling machine. Background Art

[0002] The plunger filling machine has become a commonly used equipment in the filling field because of its advantages such as simple control, convenient operation, and ability to achieve quantitative filling operations.

[0003] In the related art, the plunger filling machine includes a guide rail, a filling valve and a lifting mechanism. The guide rail has an annular guide groove, and the guide rail has a first connection position and a second connection position. The first connection position is rotatably connected to the column through a pivot, and the second connection position is connected to the lifting mechanism. The lifting mechanism can drive the second connection position of the guide rail to rise and fall, which is manifested as the second connection position of the guide rail rotating with the pivot of its first connection position as the rotation axis. The filling valve is movably installed on the guide rail along the extension direction of the guide groove. When the filling valve moves along the guide groove, the filling valve will first rise a certain stroke and then fall a certain stroke, thereby realizing quantitative filling.

[0004] However, since the connection between the output end of the lifting mechanism and the guide rail is a rigid connection, during the quantitative adjustment process of the plunger filling machine, when the lifting mechanism drives the second connection position of the guide rail to rise and fall to different heights, a displacement deviation will occur during the rotation of the guide rail around the pivot of its first connection position, making the connection between the output end of the lifting mechanism and the guide rail easily broken due to stress, which increases the maintenance cost of the lifting mechanism and affects the filling efficiency.

[0037] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0038] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0039] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0044] Figure 1 The schematic diagram of the structure of the plunger filling machine provided in the embodiment of the present application is shown. Figure 1 As shown, the plunger filling machine includes a material storage barrel (not shown in the figure), a filling valve 100 and a quantitative adjustment device, wherein the quantitative adjustment device includes a column 1, a guide rail 2 and a lifting mechanism 3, the guide rail 2 and the column 1 are rotatably matched, the output end of the lifting mechanism 3 is connected to the guide rail 2, the material storage barrel is installed in the space formed by the guide rail 2 and is used to accommodate the material to be filled, the filling valve 100 is connected to the material storage barrel, and the lifting mechanism 3 is used to lift a part of the guide rail 2, so that the material quantitative filling is realized during the movement of the filling valve 100 along the extension direction of the guide rail 2.

[0045] It should be noted that the filling valve 100 in the present application may adopt the plunger-type filling valve in the prior art, and the structure and principle of the plunger-type filling valve are conventional technologies for those skilled in the art and will not be described in detail here.

[0046] Figure 2 Shows Figure 1 The structural diagram of the middle plunger filling machine hides the filling valve 100. Figure 2 Combination Figure 1 As shown, the guide rail 2 is annular as a whole, and includes an upper rail 21, a lower rail 22 and a fixing member 23. The upper rail 21 and the lower rail 22 are arranged in parallel and spaced apart from each other. A plurality of fixing members 23 are arranged in spaced apart along the extension direction of the upper rail 21 and the lower rail 22 and are used to fix the upper rail 21 and the lower rail 22, so as to ensure that an annular guide groove 20 is formed between the upper rail 21 and the lower rail 22, and the filling valve 100 has a roller matched with the guide groove 20. Specifically, the wheel surface of the roller fits with the upper rail 21 and the lower rail 22, which can ensure that the filling valve 100 can move stably relative to the guide rail 2, and can also reduce the friction between the filling valve 100 and the guide rail 2 during the movement.

[0047] Furthermore, the upper rail 21 has a notch for the filling valve 100 to be installed in the guide groove 20. When installing the filling valve 100, the roller of the filling valve 100 can be moved from the notch from top to bottom to a position abutting against the lower rail 22, and then slid in the horizontal direction to insert the roller of the filling valve 100 into the guide groove 20 formed by the upper rail 21 and the lower rail 22, so as to ensure that the filling valve 100 is stably installed in the guide groove 20.

[0048] The guide rail 2 has a first connection position 201 and a second connection position 202, wherein the first connection position 201 is connected to the column 1 by a pivot, and the second connection position 202 is connected to the lifting mechanism 3. This arrangement facilitates the connection between the guide rail 2 and the column 1 and the lifting mechanism 3.

[0049] There are two first connection positions 201, two columns 1, and the columns 1 are connected one by one with the first connection positions 201. In this way, the guide rail 2 has two support points, which can prevent the guide rail 2 from shaking, thereby ensuring the overall stability of the guide rail 2, and further ensuring the quantitative filling accuracy of the filling valve 100.

[0050] There are two second connection positions 202, and two lifting mechanisms 3, and the lifting mechanisms 3 are connected to the second connection positions 202 one by one. The two lifting mechanisms 3 can not only stably lift the second connection positions 202 of the guide rail 2, but also serve as support for the guide rail 2, thereby improving the bearing capacity of the guide rail 2 for multiple filling valves 100, and ensuring the stability of the guide rail 2 and the quantitative filling accuracy of the filling valve 100.

[0051] In this embodiment, the distance between the two first connection positions 201 is smaller than the diameter of the circle where the guide groove 20 is located, and the distance between the two second connection positions 202 is smaller than the diameter of the circle where the guide groove 20 is located. In this way, the four connection positions can serve as four support positions, which can ensure that the overall force of the guide rail 2 is balanced, avoid shaking of the guide rail 2, and improve the stability of the movement of the filling valve 100.

[0052] Figure 3 A schematic structural diagram of two lifting mechanisms 3 provided in an embodiment of the present application is shown. Figure 4 A partial exploded schematic diagram of the lifting mechanism 3 provided in the embodiment of the present application is shown. Figure 5 FIG. 2 shows a partial structural diagram of the lifting mechanism 3 provided in the embodiment of the present application, in which part of the switching structure 33 is hidden. Figures 3 to 5 Combined with Figure 2As shown, the lifting mechanism 3 includes a lifting drive member 31, a lifting member 32 and a transfer structure 33. The output end of the lifting drive member 31 is connected to the lifting member 32 and is used to drive the lifting member 32 to lift in the vertical direction. The lifting member 32 has a long hole 321 extending in the horizontal direction. A part of the transfer structure 33 is movably installed in the long hole 321 along the extension direction of the long hole 321, and the other part is connected to the second connecting position 202 of the guide rail 2.

[0053] When the lifting drive member 31 drives the lifting member 32 to lift and lower the adapter structure 33 and the second connection position 202 of the guide rail 2, since the first connection position 201 of the guide rail 2 is rotatably connected to the column 1, the second connection position 202 of the guide rail 2 rotates with the pivot of the first connection position 201 as the rotation axis. At this time, the adapter structure 33 connected to the second connection position 202 of the guide rail 2 will produce a certain displacement deviation in the horizontal direction, so that the adapter structure 33 moves in the horizontal direction relative to the long hole 321 of the lifting member 32 to compensate for the displacement deviation, thereby reducing the risk of breakage at the connection between the adapter structure 33 and the lifting member 32, reducing maintenance costs, and at the same time extending the service life of the lifting mechanism 3 and improving filling efficiency.

[0054] The two lifting mechanisms 3 are connected by a transmission member, so that the two can work synchronously. Further, in the two lifting mechanisms 3, the lifting drive member 31 of one lifting mechanism 3 is a motor, and the lifting drive member 31 of the other lifting mechanism 3 is a hand wheel. The lifting mechanism 3 whose lifting drive member 31 is a motor is used to automatically drive the second connection position 202 of the guide rail 2 to rise and fall, and the lifting mechanism 3 whose lifting drive member 31 is a hand wheel is used to manually drive the second connection position 202 of the guide rail 2 to rise and fall. Furthermore, in the quantitative test stage, the hand wheel can be manually operated to determine the corresponding relationship between the lifting height of the second connection position 202 of the guide rail 2 and the filling amount, and the corresponding parameters can be input into the control system, so that in the automatic operation process, the control system can control the motor to drive the second connection position 202 of the guide rail 2 to rise and fall to the required height according to the filling requirements.

[0055] The lifting mechanism 3 also includes a screw rod and nut assembly, which includes a screw rod 341 and a nut seat 342 threadedly connected to the screw rod 341. The screw rod 341 is in transmission connection with the lifting drive member 31, and the nut seat 342 is fixedly connected to the lifting member 32. When the lifting drive member 31 drives the screw rod 341 to rotate, the nut seat 342 can drive the lifting member 32 to rise and fall relative to the screw rod 341, and then drive the transfer structure 33 to rise and fall through the lifting member 32.

[0056] The lifting mechanism 3 also includes a frame 35, which includes a top plate 351, a bottom plate 352 and a side plate 353 connecting the top plate 351 and the bottom plate 352. The lifting drive member 31 is installed on the top plate 351, and the two ends of the screw rod 341 are rotatably installed on the top plate 351 and the bottom plate 352 respectively.

[0057] In order to ensure that the lifting member 32 can be stably lifted and lowered in the vertical direction, the side plate 353 has a guide hole 3531 extending in the vertical direction, and the lifting member 32 has a guide shaft 322 slidably matched with the guide hole 3531 .

[0058] Furthermore, the lifting mechanism 3 further includes a guide rod 36, which extends in the vertical direction and is fixed on the top plate 351 and the bottom plate 352 of the frame body 35, and the lifting member 32 has a through hole 323 that is slidably matched with the guide rod 36. In this embodiment, there are two guide rods 36, which are respectively located on both sides of the screw rod 341, and the lifting member 32 has two through holes 323, and the two guide rods 36 are respectively slidably matched with the two through holes 323. For example, a sliding bearing can also be provided between the lifting member 32 and the guide rod 36 to ensure that the lifting member 32 is stably lifted and lowered relative to the guide rod 36.

[0059] Continue to see Figures 4 to 5 As shown, the transfer structure 33 includes a transfer member 331 and a connecting member 332, the transfer member 331 includes a first transfer portion 3311 and a second transfer portion 3312, the first transfer portion 3311 is detachably fixedly connected to the connecting member 332, the connecting member 332 is movably inserted into the long hole 321, and the second transfer portion 3312 is detachably fixedly connected to the guide rail 2. Such a configuration can facilitate the detachable connection between the transfer structure 33 and the connecting member 332 and the guide rail 2, thereby improving assembly efficiency.

[0060] There are two first adapter parts 3311, which are arranged in parallel and spaced apart. One end of the adapter 331 is detachably fixedly connected to the first adapter part 3311, and the other end is detachably fixedly connected to the second adapter part 3312. For example, the connecting member 332 can be a bolt, which passes through one first adapter part 3311, then passes through the long hole 321 of the lifting member 32, and then passes through the other first adapter part 3311, and finally is connected with the bolt by a nut to achieve the limited fixing of the bolt.

[0061] There are two second adapter parts 3312, which are arranged in parallel and spaced apart, one of which is connected to the top of the guide rail 2, and the other is connected to the bottom of the guide rail 2. Such an arrangement can ensure the stability of the connection between the adapter structure 33 and the guide rail 2, thereby ensuring the stability of the movement of the filling valve 100 and the quantitative filling accuracy.

[0062] The transfer structure 33 further includes a sliding sleeve 333, which is disposed outside the connecting member 332. The sliding sleeve 333 includes a sliding portion 3331 and a limiting portion 3332 connected to the sliding portion 3331 in a stepped manner. The sliding portion 3331 and the long hole 321 are slidably matched along the extending direction of the long hole 321, and the limiting portion 3332 is located outside the long hole 321. By using the sliding portion 3331 of the sliding sleeve 333 and the long hole 321 to slide, the stability of the transfer structure 33 relative to the lifting member 32 in the horizontal direction can be further improved, so as to better compensate for the displacement deviation generated during the lifting process of the second connecting position 202 of the guide rail 2.

[0063] Figure 6 FIG. 3 is a cross-sectional view of the adapter structure 33 provided in the embodiment of the present application at the connection member 332. Figure 6 Combination Figure 4 and Figure 5 As shown, there are two sliding sleeves 333 , which are arranged opposite to each other and are both sleeved outside the connecting member 332 , and the two sliding sleeves 333 are both slidably matched with the long hole 321 , thereby ensuring that the entire adapter structure 33 moves stably along the extension direction of the long hole 321 .

[0064] In addition, through the setting of the sliding sleeve 333, when selecting the connecting member 332, a universal member can be selected. There is no need to ensure that the connecting member 332 and the long hole 321 are precisely slidably matched. It only requires that the sliding part 3331 of the sliding sleeve 333 can be precisely slidably matched with the long hole 321, which can reduce material costs.

[0065] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
