Description

Technical Field

[0001] This invention relates to the field of filter cartridge filling technology, and in particular to a circulating filter cartridge filling device. Background Technology

[0002] Fiber filters are widely used in daily consumer products (air fresheners), electronic products (USB mini humidifiers, electronic smoke atomizers, miniature computer sweepers), and medical products (laboratory pipettes, oxygen concentrators, humidification bottles), and are a consumable product with extremely high demand.

[0003] Cigarette filters are also a type of filter element. To cater to customer preferences, filters containing flavor capsules have appeared on the market. These filters consist of a long cylindrical fiber filter element and a filter tip filled inside the fiber filter element. Both ends of the filter element are sealed with fiber plugs, which is both aesthetically pleasing and ensures a tight seal, preventing the flavor capsule from falling out. Therefore, to meet market demands, there is an urgent need for a production device that can continuously produce filters filled with flavor capsules. Summary of the Invention

[0015] Furthermore, the rotating assembly includes two mounting plates, a motor, and a rotating rod;

[0016] Two mounting plates are correspondingly arranged. The intermediate shaft, two mounting discs, two pushing components, and two irregularly shaped cam discs are all located between the two mounting plates. The two irregularly shaped cam discs are respectively fixedly arranged on the side walls of the opposite surfaces of the two mounting plates. The rod of the rotating rod passes through the central axis of the intermediate shaft and the two mounting discs. The two ends of the rotating rod pass through the central axis of the two irregularly shaped cam discs and the mounting plates, respectively. The two ends of the rotating rod are rotatably connected to the two irregularly shaped cam discs and the mounting plates, respectively.

[0017] The output shaft of the motor is connected to one end of the rotating rod.

[0018] Furthermore, the placement slot assembly includes two plug placement slots, one burst bead placement slot, and one filter element placement slot, wherein the plug placement slot, the burst bead placement slot, and the filter element placement slot are interconnected.

[0019] The burst bead placement slot and the filter element placement slot are arranged adjacent to each other, and the two plug placement slots are respectively arranged on the opposite outer sides of the burst bead placement slot and the filter element placement slot;

[0020] The burst bead placement slot is used to place burst beads; the burst beads can slide within the burst bead placement slot;

[0021] The filter cartridge placement slot is used to place long cylindrical fiber filter cartridges;

[0022] The plug placement groove is used to place fiber plugs; the fiber plugs can slide within the plug placement groove.

[0023] Furthermore, the mounting plate includes a large mounting plate and a small mounting plate, wherein the diameter of the large mounting plate is larger than the diameter of the small mounting plate; the small mounting plate is located between the large mounting plate and the intermediate shaft.

[0024] The small mounting plate has several push rod guide holes evenly distributed around its circumference, and the push rod guide holes are adapted to the position of the plug placement slot.

[0025] The large mounting plate has a plurality of guide rod guide holes evenly distributed along its circumference, and the guide rod guide holes are located on the outer side of the outer circumferential surface of the small mounting plate.

[0035] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] This invention uses a motor to drive a rotating rod to rotate, which in turn drives the intermediate shaft and two mounting discs to rotate. When the mounting discs rotate, the pushing component also rotates. Since the irregularly shaped cam disc does not rotate, when the connecting rod passes the cam part of the cam disc, the two connecting rods move towards each other, driving the pushing rod to move. The pushing rod then pushes the popping beads and two fiber plugs placed inside the placement slot assembly toward each other, pushing the popping beads into the long cylindrical fiber filter element and pushing the two fiber plugs to both ends of the long cylindrical fiber filter element, thus sealing both ends of the long cylindrical fiber filter element, thereby completing one filling operation. Subsequently, the connecting rod moves to the flat wheel part of the cam disc, and the pushing rod returns to its original position under the action of a spring. This process is repeated, with the rotating component driving the intermediate shaft and two mounting discs to rotate circumferentially, enabling continuous cyclic filling.

[0047] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0048] See Figure 1 As shown, a circulating filter cartridge filling device according to an embodiment of this application includes an intermediate shaft 1, two mounting discs 2, two pushing components 3, two irregularly shaped cam discs 4, and a rotating assembly 5.

[0049] Several sets of placement groove assemblies 6 are evenly opened along the circumferential direction on the outer surface of the intermediate shaft 1;

[0050] Two mounting discs 2 are installed at both ends of the intermediate shaft 1;

[0051] Two pushing components 3 are respectively installed on the opposite outer sides of the two mounting plates 2;

[0052] Two irregularly shaped cam disks 4 are symmetrically arranged on the opposite outer sides of the two pushing components 3 and respectively abut against the opposite outer sides of the two pushing components 3;

[0053] The placement slot assembly 6 is used to accommodate the long cylindrical fiber filter element, the burst beads, and two fiber plugs;

[0054] The two mounting plates 2 are used to support the two pushing components 3 and guide the two pushing components 3 respectively;

[0055] The two pushing components 3 are respectively engaged with the two irregularly shaped cam disks 4 to push the burst beads into the interior of the long cylindrical fiber filter element, and push the two fiber plugs into the interior of the long cylindrical fiber filter element to seal both ends of the long cylindrical fiber filter element.

[0056] The rotating assembly 5 is used to drive the intermediate shaft 1 and the two mounting discs 2 to rotate circumferentially.

[0057] Specifically, the rotating assembly 5 adopts the following structure:

[0058] Rotating assembly 5 includes two mounting plates 501, a motor 502, and a rotating rod 503;

[0059] Two mounting plates 501 are set correspondingly. The intermediate shaft 1, two mounting discs 2, two pushing components 3 and two irregular cam discs 4 are all located between the two mounting plates 501. The two irregular cam discs 4 are respectively fixed on the side walls of the opposite surfaces of the two mounting plates 501. The rod of the rotating rod 503 is passed through the central axis of the intermediate shaft 1 and the two mounting discs 2. The two ends of the rotating rod 503 pass through the central axis of the two irregular cam discs 4 and the mounting plate 501 respectively. The two ends of the rotating rod 503 are rotatably connected to the two irregular cam discs 4 and the mounting plate 501 respectively.

[0060] The output shaft of motor 502 is connected to one end of rotating rod 503.

[0061] It should be noted that the rotating rod 503 is driven to rotate by the motor 502, and the rotating rod 503 drives the intermediate shaft 1 and the two mounting disks 2 to rotate circumferentially. The two pushing components 3 are respectively mounted on the two mounting disks 2 and can also rotate with the rotation of the mounting disks. The two irregular cam disks 4 are fixedly set with the two mounting plates 501, and the two ends of the rotating rod 503 are respectively rotatably connected to the two irregular cam disks 4. The irregular cam disks 4 do not rotate with the rotating rod 503.

[0062] Specifically, the placement slot assembly 6 includes two plug placement slots 601, one burst bead placement slot 602, and one filter element placement slot 603, with the plug placement slots 601, burst bead placement slot 602, and filter element placement slot 603 being interconnected.

[0063] The burst bead placement groove 602 and the filter element placement groove 603 are arranged adjacent to each other, and the two plug placement grooves 601 are respectively arranged on the opposite outer sides of the burst bead placement groove 602 and the filter element placement groove 603.

[0064] The burst bead placement slot 602 is used to place burst beads; the burst beads can slide within the burst bead placement slot 602.

[0065] The filter cartridge placement slot 603 is used to place long cylindrical fiber filter cartridges;

[0066] The plug placement groove 601 is used to place fiber plugs; the fiber plugs can slide within the plug placement groove 601.

[0067] It should be noted that the depth of the filter element placement groove 603 is greater than the depth of the burst bead placement groove 602 and the plug placement groove 601. This is because the long cylindrical fiber filter element has a certain wall thickness. Making the filter element placement groove 603 deeper allows the axis of the filter element placement groove 603 to be on the same straight line as the center of the burst bead and the axis of the fiber plug, so that the burst bead and the fiber plug can be filled into the interior of the long cylindrical fiber filter element more easily.

[0068] Specifically, such as Figure 1 , Figure 2 As shown, the mounting plate 2 includes a large mounting plate 201 and a small mounting plate 202. The diameter of the large mounting plate 201 is larger than the diameter of the small mounting plate 202. The small mounting plate 202 is located between the large mounting plate 201 and the intermediate shaft 1.

[0069] The small installation plate 202 has several push rod guide holes 203 evenly opened along the circumference of the plate body, and the push rod guide holes 203 are adapted to the position of the plug placement groove 601.

[0070] The large mounting plate 201 has several guide rod guide holes 204 evenly distributed along the circumference of the plate body, and the guide rod guide holes 204 are located on the outer side of the circumferential outer surface of the small mounting plate 202.

[0071] A number of push rod guide holes 203 are respectively opened in correspondence with a number of guide rod guide holes 204;

[0072] Push component 3 includes several push components 31;

[0073] like Figure 3 As shown, each push component 31 includes a push rod 311, a guide rod 312, a connecting rod 313, a rolling bearing 314, and a spring 315;

[0074] The number of push assembly 31, push rod guide hole 203 and guide rod guide hole 204 are the same;

[0075] Push rod 311 passes through the inside of push rod guide hole 203, guide rod 312 passes through the inside of guide rod guide hole 204, the same ends of push rod 311 and guide rod 312 are respectively connected to the two ends of connecting rod 313, and guide rod 312 is located between irregular cam disk 4 and guide rod 312;

[0076] The push rod 311 is parallel to the guide rod 312, and the connecting rod 313 is perpendicular to the guide rod 312;

[0077] Rolling bearing 314 is sleeved on connecting rod 313, and rolling bearing 314 abuts against irregular cam disk 4;

[0078] Spring 315 is sleeved on the push rod 311. One end of spring 315 abuts against connecting rod 313, and the other end of spring 315 abuts against large mounting plate 201.

[0079] It should be noted that the axis of the push rod 311 is on the same straight line as the axis of the fiber plug placed in the plug placement groove 601, ensuring that the push rod 311 can smoothly push the fiber plug.

[0080] Specifically, an installation rod is provided between the two mounting plates 501, and a pressure plate is provided on the installation rod. The shape of the pressure plate is adapted to the intermediate shaft 1, and a gap is left between the pressure plate and the intermediate shaft 1. The setting of the pressure plate can ensure that the material in the placement groove assembly 6 will not fall out of the placement groove assembly 6. Only when the placement groove assembly 6 is rotated to the area not covered by the pressure plate will the material in the placement groove assembly 6 fall out of the placement groove assembly 6. This can effectively prevent the material in the placement groove assembly 6 from falling out of the placement groove assembly 6 under the squeezing force of the push rod 311 or its own gravity, and ensure that the bursting beads and fiber plugs can be filled smoothly.

[0081] It should be noted that above the two end cap placement slots 601, the burst bead placement slot 602, and the filter element placement slot 603 located at the top of the intermediate shaft 1, end cap conveyors, burst bead conveyors, and filter element conveyors are respectively connected. The end cap conveyors, burst bead conveyors, and filter element conveyors can respectively convey fiber end caps, burst beads, and long cylindrical fiber filter elements into the two end cap placement slots 601, the burst bead placement slot 602, and the filter element placement slot 603. During the rotation of the intermediate shaft 1, raw materials can be continuously conveyed into the interior of several placement slot assemblies 6. With the help of the pusher assembly 31, cyclic filling can be completed.

[0082] The working process of this invention is as follows:

[0083] Motor 502 drives rotating rod 503 to rotate, which in turn drives intermediate shaft 1 and two mounting discs 2 to rotate. When mounting discs 2 rotate, pushing component 31 also rotates. Since the irregular cam disc 4 does not rotate, when connecting rod 313 passes the cam part of the cam disc, the two connecting rods 313 will move towards each other and drive pushing rod 311 to move. Pushing rod 311 can push the popping beads and two fiber plugs placed inside the placement slot component 6 towards each other, pushing the popping beads into the long cylindrical fiber filter element and pushing the two fiber plugs to the two ends of the long cylindrical fiber filter element respectively, thus completing one filling operation. Then, connecting rod 313 moves to the flat wheel part of the cam disc, and pushing rod 311 returns to its original position under the action of spring 315. In this way, rotating component 5 drives intermediate shaft 1 and two mounting discs 2 to rotate around the circumference, and together with pushing component 31, can complete the continuous cyclic filling operation.

[0084] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be construed as a limitation of the present invention.
