Detailed Implementation
[0027] The packaging device for this breathing filter element includes a base 1, an unwinding assembly 5, a covering assembly 2, a welding assembly 3, and a drive slitting assembly 4 (see the attached instruction manual). Figure 1 , 2 and 3).
[0028] The base 1 is equipped with a cover assembly 2 (see instruction manual). Figure 1 , 2 and 3).
[0029] The covering assembly 2 includes a shaping device 6, a main limiting wheel 9, a secondary limiting wheel A11, and a secondary limiting wheel B14 (see the instruction manual appendix). Figure 7 ).
[0030] A shaping device 6 is fixedly mounted at one end of the base 1 (see instruction manual appendix). Figure 7 The shaping device 6 includes a guide base plate 17, a vertical limiting plate 19, and support rods 18; two sets of support rods 18 are symmetrically and obliquely installed at one end of the guide base plate 17; two sets of vertical limiting plates 19 are symmetrically installed on the upper part of the guide base plate 17; an inclined slope 20 is provided on the upper end surface of the vertical limiting plate 19; the main limiting wheel 9 is located between the two sets of vertical limiting plates 19 (see the appendix of the instruction manual). Figure 7 ).
[0031] The purpose of setting the shaper 6 in this way is to allow the plastic film to enter the interior of the vertical limiting plate 19 and the guide base plate 17 along the support rod 18 during operation; and under the support and limitation of the main limiting wheel 9, the plastic film is always in contact with the inner side of the vertical limiting plate 19 and the guide base plate 17; thus, the plastic film can be made to have a "U" shaped cross section under the support of the vertical limiting plate 19 and the guide base plate 17, thereby ensuring that when the breathing filter enters the interior of the shaper 6 under other conveying mechanisms, the breathing filter is inside the plastic film.
[0032] Inside the shaping unit 6, two sets of main limiting wheels 9 are symmetrically mounted via a vertical plate 7 and a drive shaft B8. On one side of the shaping unit 6, a secondary limiting wheel A11 is mounted on the vertical plate 7 via a drive shaft A10. On the vertical plate 7 on the side of the secondary limiting wheel A11, a secondary limiting wheel B14 is mounted via a covered motor 12 and a drive shaft 13. The drive shaft 13 is connected to the drive shaft A10 via a drive belt A15 and a drive wheel. The drive shaft A10 is connected to the drive shaft B8 via a drive belt B16 and a drive wheel. The secondary limiting wheels A11 and B14 are installed in an alternating pattern (see the instruction manual appendix). Figure 2 , 6 and 7).
[0033] The purpose of arranging the main limiting wheel 9, the secondary limiting wheel A11, and the secondary limiting wheel B14 in this way is to ensure that during operation, when the motor 12 drives the drive shaft 13 to rotate, the drive shaft 13 can drive the drive shaft A10 and drive shaft B8 to rotate synchronously with the cooperation of the drive wheel, drive belt A15, and drive belt B16; during the synchronous rotation of the drive shaft 13, drive shaft A10, and drive shaft B8, the main limiting wheel 9, secondary limiting wheel A11, and secondary limiting wheel B14 can also rotate synchronously; during the rotation of the main limiting wheel 9, secondary limiting wheel A11, and secondary limiting wheel B14, not only can the breathing filter element be moved together with the plastic sealing film, but the cross-section of the plastic sealing film can also be kept in a "U" shape through the main limiting wheel 9, secondary limiting wheel A11, and secondary limiting wheel B14, thereby ensuring that the breathing filter element can smoothly enter the interior of the plastic sealing film.
[0034] Welding assembly 3 is mounted on the base 1 on one side of the covering assembly 2 (see instruction manual). Figure 1 , 2 And 3). Welding assembly 3 includes intermediate assembly plate 26, clamp 27 and heating welding plate 31 (see appendix to the instruction manual). Figure 6 , 9 and 10).
[0035] Two sets of clamps 27 are symmetrically mounted on the middle of the base 1 via the intermediate mounting plate 26 (see the instruction manual appendix). Figure 3 and 6 ).
[0036] The clamping device 27 includes a fixed roller 34, a movable roller 36, a mounting plate 33, and a tension spring 37 (see the instruction manual appendix). Figure 10 A mounting plate 33 is mounted on the intermediate mounting plate 26; a fixed roller 34 is mounted on the lower end of the mounting plate 33; a slider 35 is slidably mounted on the mounting plate 33 on one side of the fixed roller 34 via a guide rail; a movable roller 36 is mounted on the slider 35; a tension spring 37 is installed between the slider 35 and the mounting plate 33; the movable roller 36 always tends to move closer to the fixed roller 34 under the action of the tension spring 37 (see the instruction manual appendix). Figure 10 ).
[0037] The purpose of setting the clamp 27 in this way is to ensure that when the film passes between the moving roller 36 and the fixed roller 34, the moving roller 36 can press the upper end of the U-shaped film with a certain elasticity in cooperation with the fixed roller 34 so that they stick together.
[0038] A support plate 28 is mounted on the intermediate mounting plate 26 between the two sets of clamps 27; two sets of sliding rods 30 are symmetrically mounted on the support plate 28 through guide sliding holes 29; a heating welding plate 31 is mounted on the bottom end of the sliding rod 30; a double-headed cylinder 32 is mounted on the upper end of the support plate 28; the two ends of the double-headed cylinder 32 are connected to the corresponding sliding rods 30 (see the attached instruction manual). Figure 9During operation, the double-headed cylinder 32 can drive the heating welding plates 31 to move closer together and clamp the membrane through the sliding rod 30. In this way, the upper part of the membrane can be sealed by heat melting, so that the membrane is in a cylindrical state; thus ensuring that the breathing filter element is located inside the cylindrical membrane.
[0039] The drive slitting assembly 4 is mounted on the base 1 on one side of the welding assembly 3 (see the instruction manual appendix). Figure 4 , 5 and 6).
[0040] The drive slitting assembly 4 includes an upper extrusion conveyor belt 40, a lower extrusion conveyor belt 43, a heat-sealing and cutting integrated blade 48, a lifting cylinder 47, and a blade holder 49 (see the instruction manual appendix). Figure 11 and 12 ).
[0041] An upper extrusion conveyor belt 40 is mounted on the base 1 via an upper drive belt shaft 38 and an upper driven belt shaft 39; a lower extrusion conveyor belt 43 is mounted inside the base 1 below the upper extrusion conveyor belt 40 via a lower drive belt shaft 41 and a lower driven belt shaft 42; a conveyor motor 44 is mounted on one end of the upper drive belt shaft 38; the other end of the upper drive belt shaft 38 and one end of the lower drive belt shaft 41 are connected by a transmission gear pair 45.
[0042] When the conveyor motor 44 is working, it can drive the upper extrusion conveyor belt 40 and the lower extrusion conveyor belt 43 to rotate through the upper drive belt shaft 38, the upper driven belt shaft 39, the lower drive belt shaft 41 and the lower driven belt shaft 42 in cooperation with the transmission gear pair 45. When the upper extrusion conveyor belt 40 and the lower extrusion conveyor belt 43 rotate, they pull the film forward by extrusion conveying.
[0043] A heat-sealing and cutting integrated blade 48 is mounted on the base 1 at one end of the upper extrusion conveyor belt 40 and the lower extrusion conveyor belt 43 via a bracket 46 and a lifting cylinder 47; a blade holder 49 is mounted on the base 1 below the heat-sealing and cutting integrated blade 48 (see the instruction manual appendix). Figure 11 and 12 The heat-sealing and cutting integrated blade 48 and blade holder 49 are purchased equipment.
[0044] The unwinding assembly 5 is mounted on the base 1 below the covering assembly 2 (see the instruction manual). Figure 1 , 2 and 8).
[0045] The unwinding assembly 5 includes an unwinding shaft 21, guide rollers A22, B23, C24, and D25. The lower end of the machine base 1 is equipped with the unwinding shaft 21. Guide rollers A22 and B23 are sequentially mounted on one side of the unwinding shaft 21. Guide rollers C24 and D25 are sequentially mounted above guide rollers A22. The unwinding shaft 21 is an externally purchased component. During operation, after the plastic film roll is inserted into the unwinding shaft 21, the unwinding shaft 21 can lock the plastic film roll from the inside. When the film strip on the plastic film roll is subjected to force and moves backward, it can drive the unwinding shaft 21 to rotate and complete the unwinding operation.
[0046] When the packaging device for the breathable filter cartridge is in operation, the plastic film roll is first inserted onto the unwinding shaft 21. Then, one end of the film strip rolled up with the plastic film is passed sequentially through guide rollers A22 and B23, and then exits between guide rollers C24 and D25 (see the instruction manual appendix). Figure 8 The purpose of this arrangement is to ensure that the film belt remains taut under the action of guide rollers A22, B23, C24, and D25.
[0047] After the film belt passes through the space between guide rollers C24 and D25, it enters the interior of the vertical limiting plate 19 and guide base plate 17 along the support rod 18 of the stenter 6. Under the support and constraint of the main limiting wheel 9, the film belt is always in contact with the inner side of the vertical limiting plate 19 and guide base plate 17. In this way, the cross-section of the film belt is U-shaped under the support of the vertical limiting plate 19 and guide base plate 17. Then, the film belt passes under the secondary limiting wheel A11 and secondary limiting wheel B14 in sequence.
[0048] When the U-shaped film tape output covering component 2 enters between the moving roller 36 and the fixed roller 34 of the clamping device 27 of the welding component 3, the moving roller 36 can press the upper end of the U-shaped film with a certain elasticity under the cooperation of the fixed roller 34 so that they stick together.
[0049] Subsequently, the cylindrical film strip after being bonded to the upper part will pass sequentially between the heating welding plates 31 and between the moving roller 36 and the fixed roller 34 of the clamping device 27, and then enter between the upper extrusion conveyor belt 40 and the lower extrusion conveyor belt 43 of the drive slitting assembly 4.
[0050] After the above work is completed, the upper extrusion conveyor belt 40 and the lower extrusion conveyor belt 43 will move forward by extrusion conveying.
[0051] During the above process, other conveying equipment sequentially transports the breathable filter cores to be packaged into the interior of the vertical limiting plate 19 of the shaping device 6; at this time, the breathable filter core is located on the upper surface of the film belt; subsequently, the breathable filter core moves together with the film belt; when the breathable filter core moves to below the heating welding plate 31, the upper extrusion conveyor belt 40 and the lower extrusion conveyor belt 43 stop moving; at this time, the double-headed cylinder 32 can drive the heating welding plate 31 to move closer together and clamp the film through the sliding rod 30, so that the upper part of the film can be sealed by heat melting, making the film present a cylindrical state; ensuring that the breathable filter core is located inside the cylindrical film.
[0052] After the above actions are completed, the heating and welding plate 31 is reset; then the film belt continues to move forward; when one end of the breathing filter element moves to below the heat-sealing and cutting integrated blade 48, the film belt stops moving; the lifting cylinder 47 drives the heat-sealing and cutting integrated blade 48 to move down so that it completes the sealing and cutting work on the cylindrical film belt at one end of the breathing filter element with the cooperation of the blade holder 49; then the film belt continues to move forward one station and stops moving; the heat-sealing and cutting integrated blade 48 completes the sealing and cutting work on the other end of the cylindrical film belt of the breathing filter element with the cooperation of the blade holder 49; the cut film belt forms a bag-like structure with both ends sealed, thus completing the packaging work of the breathing filter element. The packaged breathing filter element slides out of the machine base 1 under the action of gravity, and then can be collected by other equipment.
[0053] The packaging device for the breathing filter cartridge can complete the packaging process by continuously repeating the above actions.
[0054] The packaging device for this breathing filter cartridge is compact and ingeniously designed, and can continuously complete the packaging of breathing filter cartridges without the need for manual placement of the breathing filter cartridges into the packaging bag. This solves the problem of low work efficiency of existing filter cartridge packaging devices and is particularly suitable for the needs of breathing filter cartridge packaging.
