Description

Technical Field

[0001] The invention relates to the technical field of post-processing of injection molding, in particular to a finishing device for an injection-molded filter cartridge. Background Art

[0002] Filter cartridges are widely used in the environmental protection industry (water treatment, air purification, industrial dust removal, etc.). They are mainly used for filtering liquids and gases, helping to remove pollutants and impurities, protecting the environment and promoting the sustainable use of resources. Filter cartridges are generally made using injection molding technology. After the filter cartridge is processed through the injection mold, it needs to be ground to remove burrs and irregular edges generated during the molding process and ensure a smooth surface.

[0003] Application publication number CN118721629B discloses a device for cutting and polishing water outlets for producing electronic cigarette shells, including a structural design in which a workbench, a feeding shell, a rotating mechanism, and a polishing mechanism are combined with each other. On the one hand, the first meshing teeth and the second meshing teeth can be sequentially connected to the transmission gear to achieve the purpose of automatically feeding the tubular electronic cigarette shell in the feeding channel into the cylinder and from the cylinder into the unloading channel. When the opening of the tubular electronic cigarette shell is in a horizontal state, the cutter and polishing block moving with the telescopic part can successively cut the water outlet and polish the cut marks. On the other hand, the cylinder rotating coaxially with the cylinder uses a curved groove and a ball head sliding connection to achieve the purpose of controlling the limit block to fix and release the tubular electronic cigarette shell. It has the characteristics of ingenious structural coordination, easy use, high processing efficiency and strong practicality.

[0046] Please refer to Figure 9 and Figure 10 In one embodiment of the present invention, a curved guide rail 511 is provided on the surface of the transmission pipe 51. The automatic feeding component 5 further includes a ball head rod 56, a push block 57, a push rod 58 and a C-shaped frame 59.

The C-shaped frame 59 is slidably connected to the fixed frame 13. The push block 57 and the push rod 58 are located inside the transmission pipe 51.

[0047] In an embodiment of the present invention, when the driving part 21 and the first transmission gear 24 are used to control the annular housing 22 to rotate 45 degrees or 60 degrees at a certain frequency around the central axis 23, the rotating central axis 23 drives the transmission pipe 51 and the semi-circular pipe 52 to rotate 180 degrees through the worm gear 25, the worm 55, the fifth transmission gear 54 and the fourth transmission gear 53.

[0048] Please refer to Figure 1 and Figure 11 In one embodiment of the present invention, the housing mechanism 1 further includes a liquid inlet 112, a liquid outlet 113 and a material guiding frame 16. The liquid inlet 112 and the liquid outlet 113 are provided on the surface of the sealed housing 11. The material guiding frame 16 is fixedly connected to the sealed housing 11. The liquid outlet 113 is located directly below the sealed housing 11.

[0049] Please refer to[[ID=^19]] Figure 4 Furthermore, it further includes a cleaning part 6. The cleaning part 6 includes a liquid pump 61 and a spray valve 62. The liquid pump 61 is fixedly connected to the feeding frame 12. The liquid pump 61 and the spray valve 62 are fixedly connected. The spray valve 62 is fixedly connected at the liquid inlet 112.

[0050] Please refer to Figure 5 Furthermore, a first through hole 34 and a second through hole 35 are respectively provided on the side wall of the rotating sleeve 31 and at one end close to the first tooth rail 14.

[0051] In an embodiment of the present invention, the liquid inlets 112 are distributed between the feeding port 111 and the liquid outlet 113. The discharging port 114 corresponds to the position of the material guiding frame 16. The discharging port 114 is distributed on the clockwise side of the liquid outlet 113. The included angle between the axis of the discharging port 114 and the axis of the liquid outlet 113 is 45 degrees or 60 degrees.

[0052] Working principle: The driving part 21 and the first transmission gear 24 are used to control the annular housing 22 to rotate 45 degrees or 60 degrees at a certain frequency around the central axis 23. The rotating central axis 23 drives the transmission tube 51 and the semicircular tube 52 to rotate 180 degrees through the worm gear 25, the worm 55, the fifth transmission gear 54 and the fourth transmission gear 53. When the opening of the semicircular tube 52 is aligned with the feed rack 12, the filter cartridge 8 automatically slides into the semicircular tube 52 along the inclined feed rack 12 and rotates 180 degrees. The transmission tube 51 is connected to the ball rod 56 by means of a curved guide rail 511 in a sliding manner to drive the yoke 59, the push rod 58 and the push block 57 to perform a reciprocating linear motion. The push block 57 in the reciprocating linear motion is used to quickly push the filter cartridge 8 between the grinding protrusion 33 and the flexible grinding roller 43 and then reset it. On the one hand, it can prevent the problem of material jamming during automatic feeding, and on the other hand, it can enable the grinding protrusion 33 and the flexible grinding roller 43 to grind the inside and outside of the filter cartridge 8 along the axis of the rotating sleeve 31.

[0053] When the driving portion 21 and the first transmission gear 24 continue to control the rotation of the annular housing 22, the second transmission gear 32 and the third transmission gear 42 are respectively connected to the first rack 14 and the second rack 15 in a transmission manner to drive the rotating sleeve 31 and the flexible grinding roller 43 to rotate in opposite directions. The counter-rotating grinding protrusions 33 and the flexible grinding roller 43 can, on the one hand, simultaneously grind and remove burrs from the outside and inside of the filter cartridge 8 to achieve the purpose of smoothness. On the other hand, by preventing the filter cartridge 8 from rotating synchronously with the rotating sleeve 31 or the flexible grinding roller 43, the grinding protrusions 33 and the flexible grinding roller 43 can achieve uniform contact between the filter cartridge 8 and the grinding effect, thereby improving the grinding effect.

[0054] When the rotating sleeve 31 moves to the position of the liquid inlet 112, the liquid pump 61 sprays the cleaning liquid into the rotating sleeve 31 through the spray valve 62. When the rotating sleeve 31 rotates between the inlet 111 and the outlet 114, on the one hand, the filter cartridge 8 first slides toward a position close to the center of the sealing shell 11, and then slides toward a position away from the center of the sealing shell 11, so that the grinding protrusion 33 and the flexible grinding roller 43 can simultaneously grind the filter cartridge 8 from the circumferential and axial directions, thereby improving the grinding and deburring effects. On the other hand, the cleaning liquid can wash away the waste debris generated by grinding and cool the filter cartridge 8 during the axial flow along the filter cartridge 8. The cleaned waste liquid enters the drain port 113 from the first through hole 34 and the second through hole 35, and the ground filter cartridge 8 is discharged from the outlet 114 to the guide rack 16, realizing the functions of automatic loading and unloading, efficient grinding of the inner and outer sides of the filter cartridge 8, and automatic cleaning and waste discharge.

[0055] To sum up, in the process of using the driving part 21 to control the rotation of the annular shell 22, the present application can, on the one hand, automatically load the filter cartridge 8 between the rotating sleeve 31 and the flexible grinding roller 43 by driving the semicircular tube 52 to rotate; on the other hand, it can achieve the purpose of driving the grinding protrusion 33 and the flexible grinding roller 43 to synchronously grind and remove burrs on the outside and inside of the filter cartridge 8 by connecting the second transmission gear 32 and the third transmission gear 42 to the first rack 14 and the second rack 15 respectively, and can also drive the ground filter cartridge 8 to automatically discharge from the discharge port 114, and has the characteristics of automatic loading and unloading and synchronous grinding of the inside and outside of the filter cartridge 8.
