The inlet of the above-mentioned first pipeline 110 is connected to the above-mentioned material storage barrel 10; the above-mentioned second pipeline 120 is coaxially arranged with the above-mentioned first pipeline 110, and the outlet of the above-mentioned second pipeline 120 is connected to the above-mentioned filling discharge port 20; the above-mentioned filter screen mounting plate 130 is sealed and clamped between the outlet of the above-mentioned first pipeline 110 and the inlet of the above-mentioned second pipeline 120, and a plurality of filter screen bodies 131 are installed on the above-mentioned filter screen mounting plate 130, wherein any two of the plurality of the above-mentioned filter screen bodies 131 are connected. The mesh numbers of 131 are not equal; the output end of the above-mentioned driving mechanism 140 is connected to the above-mentioned filter mounting plate 130, and the above-mentioned driving mechanism 140 is used to drive the above-mentioned filter mounting plate 130 to move, so that any one of the multiple filter bodies 131 moves between the above-mentioned first pipeline 110 and the above-mentioned second pipeline 120; the above-mentioned piezoelectric crystal 150 is arranged in a one-to-one correspondence with the above-mentioned filter body 131, one side of the above-mentioned piezoelectric crystal 150 abuts against the outer wall of the above-mentioned filter body 131, and the other side of the above-mentioned piezoelectric crystal 150 is fixedly connected to the filter mounting plate 130, and the above-mentioned piezoelectric crystal 150 is used to drive the above-mentioned filter body 131 to vibrate; the outer wall of the above-mentioned first pipeline 110 and / or the above-mentioned second pipeline 120 is provided with the above-mentioned flushing device 160, and the above-mentioned flushing device 160 is used to flush the above-mentioned filter body 131.

[0033] The filling machine filter device 100 in this embodiment is connected to the storage barrel 10 of the filling machine through the first pipeline 110, and is connected to the filling discharge port 20 through the second pipeline 120. A filter screen mounting plate 130 is provided between the first pipeline 110 and the second pipeline 120. A plurality of filter screen bodies 131 with different mesh sizes are provided on the filter screen mounting plate 130. The driving mechanism 140 can drive the above-mentioned filter screen mounting plate 130 to move, so that any one of the plurality of the above-mentioned filter screen bodies 131 moves between the first pipeline 110 and the second pipeline 120, thereby using the filter screen body 131 to filter the fluid flowing from the first pipeline 110 to the second pipeline 120, and at the same time, the driving mechanism 140 is used to switch the filter screen body 131 according to demand. At this time, there is no need to stop work and disassemble the above-mentioned filling machine filter device. The device 100 can improve the switching efficiency of the filter body 131 and the production efficiency of the filling machine. At the same time, the piezoelectric crystal 150 vibrates when an appropriate alternating voltage is applied.

Furthermore, a corresponding flushing device 160 is provided outside the first pipe 110 or the second pipe 120, or outside the first pipe 110 and the second pipe 120, to flush the filter body 131 before and after use, cleans attached impurities, ensures the cleanliness of the filter body 131, and improves the filtration effect and filtration efficiency. The filling machine filter device 100 can adjust the required filter body 131 according to demand and clean the filter body 131 in a timely manner to ensure the cleanliness of the filter body 131, thereby improving filtration efficiency and production efficiency.

[0034] Example 1

[0035] like Figure 2 As shown, the filter screen mounting plate 130 in the first embodiment is provided with a plurality of filter screen bodies 131 evenly spaced along a first direction. The output end of the driving mechanism 140 is connected to the filter screen mounting plate 130 and drives the filter screen mounting plate 130 to reciprocate along the first direction. The first direction in this embodiment is Figure 2 The filter mounting plate 130 is driven by the driving mechanism 140 to reciprocate linearly in the first direction, so that the filter body 131 corresponding to the required mesh size is moved between the first pipe 110 and the second pipe 120, and the filter mounting plate 130 is synchronously moved according to demand to adjust the required filter body 131, which has a simple adjustment method and can improve the adjustment efficiency.

[0036] The driving mechanism 140 in this embodiment can specifically be a reciprocating linear drive cylinder, a reciprocating linear drive motor, a combination of a rotary motor and a gear rack, and a combination of a rotary motor and a lead screw, etc., which will not be repeated here.

[0037] In this embodiment, a sealing ring 111 is provided at the outlet port of the first pipeline 110 and the inlet port of the second pipeline 120. The sealing ring 111 abuts against the filter mounting plate 130. The provision of the sealing ring 111 enables both the outlet port of the first pipeline 110 and the inlet port of the second pipeline 120 to be sealedly connected to the filter mounting plate 130, thereby improving the sealing effect, preventing leakage of the fluid to be filtered, and enhancing reliability.

[0038] Specifically, the filter mounting plate 130 defines a mounting slot, within which the piezoelectric crystal 150 is positioned. The vibration frequency of the piezoelectric crystal 150 is adjustable, ranging from 20kHz to 40kHz; its vibration amplitude is also adjustable, ranging from 0.1mm to 1mm, to accommodate fluids of varying viscosities. The power of the piezoelectric crystal 150 is also adjustable, tailored to the fluid flow rate. This will not be further detailed here.

[0039] Example 2

[0040] like Figure 3 As shown, the filling machine filter device 100 in the second embodiment differs from the first embodiment only in the structures of the filter mounting plate 130 and the drive mechanism 140. Specifically, the filter mounting plate 130 is not coaxial with the first pipeline 110. The filter mounting plate 130 is evenly spaced along the circumference of the filter mounting plate 130. The distance between the central axis of any filter body 131 and the central axis of the filter mounting plate 130 is A, and the distance between the central axis of the first pipeline 110 and the central axis of the filter mounting plate 130 is B, where A=B. Thus, by driving the filter mounting plate 130 through the drive mechanism 140, the corresponding filter body 131 can be aligned with the first pipeline 110. The filter mounting plate 130 can also be synchronously moved as needed to adjust the desired filter body 131. This simplifies the adjustment process and improves adjustment efficiency.

[0041] Furthermore, the output end of the drive mechanism 140 is connected to the central axis of the filter mounting plate 130. The drive mechanism 140 is used to drive the filter mounting plate 130 to rotate about its own axis. This drives the filter mounting plate 130 to move about its own axis, causing the filter body 131 to perform a circular motion around the central axis of the filter mounting plate 130, thereby aligning the desired filter body 131 with the first pipeline 110 for filtration.

[0042] The driving mechanism 140 in this embodiment is selected as a rotary motor, which can reliably and stably drive the filter mounting plate 130 to rotate around its own axis.

[0043] In this embodiment, the flushing device 160 includes a flushing pipe 161 and a flushing nozzle 162. The flushing pipe 161 is disposed on the outer wall of the first pipe 110 and / or the outer wall of the second pipe 120. The flushing pipe 161 extends radially along the first pipe 110. The flushing nozzle 162 is disposed at one end of the flushing pipe 161 away from the first pipe 110. The flushing nozzle 162 can flush the filter body 131 facing the flushing nozzle 162. As a result, the flushing nozzle 162 can clean the center of the filter body 131 directly, achieving a better cleaning effect.

[0044] Furthermore, there are 8 flushing nozzles 162 arranged along a circular array, and the backwashing pressure thereof is adjustable from 10MPa to 20MPa. Pulse jet cleaning fluid is used during flushing, and the pulse period is 0.1s to 0.5s. The flushing nozzle 162 is linked with the driving mechanism 140. When the driving mechanism 140 drives the filter body 131 to rotate circumferentially, the flushing nozzle 162 cleans different positions of the filter body 131, thereby achieving 360° cleaning of the filter body 131 without dead angles, and achieving a better cleaning effect.

[0045] In this embodiment, one end of the flushing pipe 161 is connected to the cleaning liquid storage barrel, and the other end is connected to the above-mentioned flushing nozzle. After being pumped and pressurized, the liquid is ejected from the flushing nozzle 162 to efficiently clean the filter body 131. Specifically, the above-mentioned cleaning liquid can be a water-based cleaning agent, such as deionized water added with surfactants, emulsifiers, and penetrants such as sodium metasilicate, sodium hydroxide, sodium carbonate, sodium perfluorooctanoate, and sodium citrate, which is suitable for cleaning the filter body 131 after being filled with water-based ointments and cosmetic emulsions. The above-mentioned cleaning liquid can also be a solvent-based cleaning agent or an emulsified cleaning agent, such as hydrocarbon cleaning agents, kerosene, gasoline, alcohol, acetone, and other organic solvents, which can dissolve the filter body 131 after being filled with oily fluids such as grease pastes and lubricating ointments.

[0046] Specifically, the first pipeline 110 can be provided with a flushing device 160 to flush and clean the filter body 131 on one side, or two flushing devices 160 can be relatively set to clean the filter body 131 on both sides of the first pipeline 110; or, the second pipeline 120 can be provided with a flushing device 160 to flush and clean the filter body 131 on one side, or two flushing devices 160 can be relatively set to clean the filter body 131 on both sides of the second pipeline 120; or the first pipeline 110 is provided with a flushing device 160, and the second pipeline 120 is provided with a flushing device 160, and the two flushing devices 160 can be located on the same side or on different sides; or the first pipeline 110 and the second pipeline 120 are both provided with two flushing devices 160, which will not be repeated here.

[0047] Example 3

[0048] like Figure 4 As shown, the difference between the filling machine filter device 100 in the third embodiment and the above-mentioned embodiments 1 and 2 lies only in the difference in the driving mechanism 140 and the filter screen mounting plate 130 mechanism. Specifically, the above-mentioned filter screen mounting plate 130 includes a plurality of mounting plate splits 132 evenly spaced along the circumference of the above-mentioned first pipeline 110, and the above-mentioned driving mechanism 140 includes a plurality of reciprocating driving members 141 evenly spaced along the circumference of the above-mentioned first pipeline 110. The above-mentioned filter screen bodies 131 are coaxially arranged with the above-mentioned mounting plate splits 132 in a one-to-one correspondence, and the output ends of the above-mentioned reciprocating driving members 141 are connected to the above-mentioned mounting plate splits 132 in a one-to-one correspondence, so that any one of the plurality of above-mentioned filter screen bodies 131 moves along the radial direction of the above-mentioned first pipeline 110 to between the above-mentioned first pipeline 110 and the above-mentioned second pipeline 120. The filling machine filter device 100 in the third embodiment uses multiple split mounting plate segments 132 to correspondingly mount the above-mentioned filter body 131. Each mounting plate segment 132 is driven by a reciprocating drive member 141, so that the corresponding filter body 131 reciprocates radially, so that the required filter body 131 moves radially between the first pipeline 110 and the second pipeline 120 to achieve a filtering effect.

[0049] When the filling machine filter devices in Examples 1 and 2 need to cross several filter bodies 131 for adjustment, the filter mounting plate 130 needs to move a large stroke. At this time, the filter body 131 that is crossed also needs to pass between the first pipeline 110 and the second pipeline 120, which will cause contamination of the filter body 131. Compared with the filling machine filter devices in Examples 1 and 2, the filling machine filter device in Example 3 can control the movement of each filter body 131 individually. When the required filter body 131 needs to be adjusted, only the corresponding two reciprocating drive members 141 need to be retracted and extended respectively, without the participation of other filter bodies 131, and the adjustment operation is simpler. However, the number of reciprocating drive members 141 and mounting plate split 132 used in Example 3 is large, the structure is more complex, and the manufacturing cost is also higher.

[0050] The reciprocating drive member 141 can be specifically selected as a reciprocating linear drive cylinder, a reciprocating linear drive motor, a combination of a rotary motor and a gear rack, and a combination of a rotary motor and a lead screw, etc., which will not be repeated here.

[0051] Furthermore, the piezoelectric crystals 150 are disposed one-to-one in correspondence with the mounting plate segments 132. By disposing the piezoelectric crystals 150 one-to-one in correspondence with the mounting plate segments 132, the piezoelectric crystals 150 can be energized and controlled to vibrate and clean the filter bodies 131 corresponding to the piezoelectric crystals 150.

[0052] This embodiment further provides a filling machine, comprising a material storage barrel 10 and a filling outlet 20. A filling machine filter device 100 as described in any of the above-described solutions is disposed between the material storage barrel 10 and the filling outlet 20. By using the filling machine filter device 100 as described in any of the above-described solutions, the filling machine achieves the beneficial effects of the filling machine filter device 100 as described in any of the above-described solutions. Specifically, the filling machine can use the driving mechanism 140 to switch the filter body 131 according to demand. At this time, there is no need to stop work and disassemble the above-mentioned filling machine filter device 100, which can improve the switching efficiency of the filter body 131 and the production efficiency of the filling machine; at the same time, the piezoelectric crystal 150 will vibrate when passing through an appropriate alternating voltage, and the high-frequency vibration generated by the power supply of the piezoelectric crystal 150 is used to excite the vibration of the filter body 131 between the first pipeline 110 and the second pipeline 120, thereby removing impurities attached to the filter body 131 and preventing the filter body 131 from being blocked during filtration; further, a corresponding flushing device 160 is provided outside the first pipeline 110 or the second pipeline 120, or outside the first pipeline 110 and the second pipeline 120, so that the filter body 131 is flushed before and after use to clean the attached impurities and ensure the cleanliness of the filter body 131, without the need to disassemble, maintain and clean the filter body 131, which can not only improve the filtering effect but also improve the cleaning efficiency.

[0053] This embodiment further provides a filling and filtering adjustment method, which uses the filling machine described in the above scheme, including the following steps: S1, starting the filling machine, and selecting the corresponding mesh size of the filter body 131 according to the properties of the raw materials in the above storage barrel 10; S2, starting the above drive mechanism 140, so that the above filter mounting plate 130 moves, and drives the above filter body 131 selected in step S1 to move between the above first pipeline 110 and the above second pipeline 120; S3, detecting the fluid pressure and fluid flow in the above first pipeline 110 and the above second pipeline 120, and the measured actual pressure difference is ΔP 实际 =P1-P2, where P1 is the pressure of the first pipeline 110, P2 is the pressure of the second pipeline 120, and the measured flow rate of the first pipeline 110 is Q 实际 ; Establish the theoretical pressure difference model of the filter body 131: Where K is the initial resistance coefficient of the filter body 131, ρ is the density of the fluid in the first pipeline, Q 额定 is the rated flow rate of the fluid in the first pipeline 110, A is the initial effective flow area of ​​the filter body 131; S4, determine whether it is blocked, and define the blockage coefficient C, If 1<C<2, it is determined to be a slight blockage, and the piezoelectric crystal 150 is turned on to vibrate and clean the filter body 131; if C≥2, it is determined to be a serious blockage, and the filling machine is stopped at this time, and the driving mechanism 140 is turned on to move the filter mounting plate 130, driving the filter body 131 selected in step S1 to move out from between the first pipeline 110 and the second pipeline 120, and turning on the flushing device 160 to flush the filter body 131.

[0054] The filling and filtering adjustment method uses the aforementioned filling machine filter device 100 and can switch the filter body 131 as needed using the drive mechanism 140. In this case, there is no need to stop the machine and disassemble the aforementioned filling machine filter device 100, which can improve the switching efficiency of the filter body 131 and the production efficiency of the filling machine. At the same time, the flow rate and pressure difference of the fluid are monitored in real time. When the filter body 131 is slightly clogged, the piezoelectric crystal 150 is vibrated when an appropriate alternating voltage is applied. The high-frequency vibration generated by the power supply of the piezoelectric crystal 150 excites the filter body 131 between the first pipeline 110 and the second pipeline 120 to vibrate, thereby removing impurities attached to the filter body 131 and preventing the filter body 131 from being clogged during filtration. Moreover, when the filter body 131 is seriously clogged, the flushing device 160 is used to flush the filter body 131. Impurities attached can be cleaned without disassembling the filter body 131. This not only ensures the cleanliness of the filter body 131 but also improves maintenance efficiency, thereby improving the filtration effect and filtration efficiency.

[0055] Specifically, when selecting the mesh size of the filter body 131 in step S1, it is necessary to match the particle size distribution and fluidity requirements of the components of the fluid to be filtered (cosmetics in this embodiment), while considering the stability of the production process and the filtration efficiency; among them, the higher the mesh size, the higher the filtration accuracy, but the risk of clogging may increase; if the mesh size is too low, impurities cannot be effectively intercepted. For example, for cosmetics containing large particles / fibers (such as scrubs and essences containing plant fibers), a filter body 131 with a mesh size of 80 to 100 is selected during filtration, which can both intercept large particles and avoid sudden pressure increases; for high-viscosity products (such as creams and wax-based products), when their viscosity is greater than 5000cP, a filter body 131 with a mesh size of 30 to 60 is preferably selected to ensure fluidity and reduce shear force to prevent structural damage; for cosmetics containing powders / suspended matter (such as liquid foundation and pastes containing pearl powder), the mesh size needs to be selected according to the particle size of the powder: if the particle size is greater than 100μm, a filter body 131 with a mesh size of 40 to 60 is selected; if the particle size is between 10μm and 50μm, a filter body 131 with a mesh size of 100 to 200 is selected.
