Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery and equipment, in particular to a feeding structure, a material conveying device and a filter rod composite device. Background Art

[0002] The "water cup" fastener is a functional component added to the filter rod. It's conical (or cup-shaped) and contains a sealed liquid. By squeezing the fastener, the liquid soaks into the filter rod's filaments, filtering out most of the tar, carbon monoxide, and other particulate matter produced during smoking. This reduces the harmful effects of smoke on smokers and improves the smoking experience.

[0003] In the prior art, there is a type of mechanical device specifically designed for conveying "cup" fixtures, such as that shown in publication number CN116946685A. When conveying the "cup" fixtures, a feeding pusher pushes the "cup" fixtures fed from a feed pipe into the accommodating cavity of a turntable, thereby feeding the "cup" fixtures one by one. When the accommodating cavity of the turntable rotates to the discharge position, the discharge assembly pushes the "cup" fixtures out of the turntable, thereby feeding the "cup" fixtures one by one into subsequent equipment.

[0004] However, in the prior art, when the feed pushing member pushes the first "water cup" firmware into the accommodating cavity of the turntable, the "water cup" firmware in the feed tube will continue to be transported forward. During the movement of the feed pushing member, it is easy to drive the next "water cup" firmware in the feed tube to move, thereby causing the next "water cup" firmware to deviate from the predetermined position, thereby affecting the stability of subsequent feeding.

[0037] The utility model provides a feeding structure, which includes a turntable and a feeding assembly; the turntable has a feeding position and a discharging position, and a accommodating cavity for accommodating materials is provided in the turntable; the feeding assembly includes a feeding conveying unit, a pushing member and a blocking member; the discharge port of the feeding conveying unit is arranged corresponding to the feeding position of the turntable, so as to convey the materials one by one to the feeding position of the turntable; the pushing member is movably arranged at the feeding position of the turntable, so as to push a single material in the feeding position of the turntable into the accommodating cavity; the blocking member is movably arranged at the front side of the pushing member, so as to block the material in the feeding conveying unit when the pushing member pushes the material. The blocking member is provided in the feeding structure. When the pushing member pushes the first material in the feeding position of the turntable, the blocking member can simultaneously block the second material in the feeding conveying unit to prevent the material in the feeding conveying unit from continuing to be conveyed forward, so that the second material will not be driven to move during the movement of the pushing member, and the position of the second material will not be offset. After the pushing member and the blocking member are reset, the second material can be smoothly conveyed to the predetermined position, thereby ensuring the stability of the feeding.

[0038] Please refer to Figures 1 to 4 This embodiment provides a feeding structure 100, which includes a turntable 10 and a feeding assembly 20. The turntable 10 has a feeding position 11 and a discharging position 12, and a receiving cavity 13 is defined in the turntable 10 for receiving material 200. In one embodiment, the material 200 is specifically a "water cup" fixture for adding to the filter rod.

[0039] The feeding assembly 20 comprises a feeding conveying unit 21, a pushing member 22 and a blocking member 23. The feeding conveying unit 21 is arranged at the feeding position 11 of the rotary disc 10, and is used to convey the materials 200 to the feeding position 11 one by one. That is, the feeding conveying unit 21 is the source of the materials 200 in the whole structure. The feeding conveying unit 21 can continuously convey the materials 200 sent by the upstream equipment to the feeding position 11, and the feeding conveying unit 21 only conveys one material 200 to the feeding position 11 at a time. The pushing member 22 is movably arranged at the feeding position 11, and is used to push the single material 200 in the feeding position 11 into the containing cavity 13. That is, the pushing member 22 is located at the area where the feeding position 11 is located, and the pushing member 22 can move, so that the material 200 in the feeding position 11 can be pushed into the containing cavity 13 through the movement of the pushing member 22, thereby realizing the transfer of the single material 200 from the feeding conveying unit 21 to the rotary disc 10. Through the reciprocating movement of the pushing member 22, the transfer of the materials 200 to the rotary disc 10 one by one is realized. The blocking member 23 is movably arranged at the front side of the pushing member 22, that is, the blocking member 23 is located at the front side of the pushing member 22, and the blocking member 23 is movably arranged. Here, the front side is referred to the conveying direction of the feeding conveying unit 21. When the material 200 is conveyed to the feeding position 11 through the feeding conveying unit 21, the material 200 needs to pass through the area where the blocking member 23 is located first, and then flows into the feeding position 11. The blocking member 23 is used to block the material 200 in the feeding conveying unit 21 when the pushing member 22 pushes the material 200. That is, when the pushing member 22 pushes the material 200 in the feeding position 11 to the containing cavity 13, the blocking member 23 can move synchronously, thereby blocking the material 200 in the feeding conveying unit 21 at the front side of the pushing member 22, and avoiding the material 200 from continuously moving to the feeding position 11.

[0040] It can be understood that the feeding structure in the prior art only has the pushing member to push the material in the feeding position, and when the pushing member pushes the material, the feeding pipe still conveys the material to the feeding position, so that the pushing member is easy to drive the material in the next position to deviate during the movement of the pushing member (for example, when the pushing member is reset), and the material in the next position deviates from the predetermined position, thereby affecting the stability of the subsequent material feeding.

[0041] The feeding structure 100 provided in this embodiment is provided with the blocking member 23. When the pushing member 22 pushes the material 200 in the feeding position 11, the blocking member 23 can block the front side of the pushing member 22, thereby blocking the material 200 in the feeding conveying unit 21 and preventing the feeding conveying unit 21 from continuously conveying the material 200 into the feeding position 11. In this way, during the process of the pushing member 22 pushing the material and during the process of the pushing member 22 returning to its original position, since the subsequent material 200 has not entered the feeding position 11, the pushing member 22 will not cause the subsequent material 200 to deviate, thereby ensuring the stability of feeding.

[0042] The blocking member 23 can move synchronously with the pushing member 22 (when the pushing member 22 pushes the material 200, the blocking member 23 moves synchronously to block the subsequent material 200; when the pushing member 22 retracts and resets, the blocking member 23 retracts and resets synchronously). Alternatively, the blocking member 23 and the pushing member 22 can move in a sequential order (for example, the pushing member 22 can move first, and then the blocking member 23 moves, etc.), which can be selected according to actual needs. The blocking member 23 and the pushing member 22 can use the same power source or different power sources, as long as they can drive the blocking member 23 and the pushing member 22 to move.

[0043] Specifically, in one embodiment, the pushing member 22 and the blocking member 23 are movable along the radial direction of the turntable 10, so that the material 200 can be pushed into the accommodating cavity 13 in a desired posture more stably.

[0044] Preferably, in one embodiment, the feed conveying unit 21 includes a driving wheel assembly 211, a tensioning wheel assembly 212, a cloth belt 213, a mounting plate 214, and a drive motor 215. The tensioning wheel assembly 212 is arranged parallel to and spaced apart from the driving wheel assembly 211. The cloth belt 213 is wound around the driving wheel assembly 211 and the tensioning wheel assembly 212 and passes through the mounting plate 214. The drive motor 215 is connected to the driving wheel assembly 211 to drive the driving wheel assembly 211 to rotate. In other words, in this embodiment, the feed conveying unit 21 specifically adopts a conveyor belt structure to convey the material 200.

[0045] Preferably, in one embodiment, the fabric belt 213 is provided with a plurality of suction holes 2131, arranged sequentially along the length of the fabric belt 213. A negative pressure channel is provided in the mounting plate 214 for communication with the suction holes 2131. The mounting plate 214 is also provided with a suction port 2141 connected to the negative pressure channel, for connection to an external negative pressure device. In other words, in this embodiment, the feed conveying unit 21 specifically utilizes a suction belt structure. By connecting an external negative pressure device, negative pressure is generated at the suction holes 2131, thereby stably adsorbing the material 200 onto the fabric belt 213 for conveyance. Compared to the prior art, this embodiment utilizes a suction belt structure to convey the material 200, which not only improves conveying stability but also reduces the risk of material 200 becoming stuck or clogged.

[0046] Preferably, in one embodiment, the pushing member 22 and the blocking member 23 are connected to the same driving source. That is to say, in this embodiment, the power for the movement of the pushing member 22 and the blocking member 23 is provided by the same driving source. Specifically, in one embodiment, the pushing member 22 and the blocking member 23 are driven by a motor 24, and the pushing member 22 and the blocking member 23 are connected to the crank chute structure at the output end of the motor 24. The crank chute structure is driven by the motor 24 to operate, thereby driving the pushing member 22 and the blocking member 23 to perform reciprocating linear motion. By connecting the pushing member 22 and the blocking member 23 to the same driving source, the driving structure can be simplified, and the synchronization of the operation of the pushing member 22 and the blocking member 23 can also be guaranteed.

[0047] Preferably, in one embodiment, the accommodating cavity 13 is opened on the circumferential surface of the turntable 10, and a plurality of the accommodating cavities 13 are provided, and the plurality of the accommodating cavities 13 are sequentially spaced along the circumference of the turntable 10. By providing a plurality of the accommodating cavities 13, the transfer efficiency of the material 200 can be further improved.

[0048] Preferably, in one embodiment, at least two feed assemblies 20 are provided: one feed assembly 20 is used to feed the material 200 into the accommodating chamber 13 in a forward direction, and the other feed assembly 20 is used to feed the material 200 into the accommodating chamber 13 in a reverse direction. Accordingly, the turntable 10 has at least two feed positions 11. That is, both feed assemblies 20 are used to feed the material 200 into the accommodating chamber 13, but the two feed assemblies 20 have different feed positions. After one feed assembly 20 feeds the material 200, the material 200 is distributed in the accommodating chamber 13 in a forward direction (the bottom wall of the material 200 faces the bottom wall of the accommodating chamber 13); after the other feed assembly 20 feeds the material 200, the material 200 is distributed in the reverse direction (the top wall of the material 200 faces the bottom wall of the accommodating chamber 13). The terms "forward" and "direction" refer to the relative position of the material 200 and the accommodating chamber 13. With this structure, the turntable 10 can output materials 200 in two different directions when discharging materials.

[0049] Preferably, in one embodiment, only two feeding assemblies 20 are provided, and the two feeding assemblies 20 are located at opposite ends of the turntable 10. By arranging the two feeding assemblies 20 at opposite ends of the turntable 10, interference between components can be better avoided, and the material 200 transmitted by the upstream equipment can be better adapted.

[0050] Specifically, in one embodiment, the end of the blocking member 23 is provided with a blocking arm 231, located above the end of the blocking member 23. When the blocking member 23 blocks the material 200, it is specifically the blocking arm 231 that blocks the material 200. In other words, in this embodiment, the component of the blocking member 23 that blocks the material 200 is only a small portion of the blocking arm 231 at the end, rather than the entire end. This allows the blocking member 23 to move more smoothly to the material blocking position and also better prevents the blocking member 23 from compressing the material 200. It will be appreciated that the "water cup" fixture has an overall tapered structure, with one end being wider and the other gradually narrowing. The blocking arm 231 allows the blocking member 23 to extend beyond the narrow end of the first material 200 when blocking the material 200, without contacting the first material 200, thereby preventing it from interfering with the feeding of the first material 200. At the same time, the blocking arm 231 extending therein can block the wider end of the secondary material 200 (such as Figure 2 As shown), the subsequent material 200 is restricted from entering the feed position 11.

[0051] At the same time, in one embodiment, a material conveying device is also provided, which is equipped with the feeding mechanism 100.

[0052] At the same time, in one embodiment, a filter rod compounding device 1000 is also provided, which includes the material conveying device, a transfer plate 300 and a filter rod conveying plate 400. The transfer plate 300 is arranged corresponding to the discharge position 12 of the turntable 10 to receive the material 200 delivered by the discharge assembly, and the filter rod conveying plate 400 is used to convey the filter rods into the transfer plate 300. The transfer plate 300 rotates to receive the material, thereby achieving compounding of the material 200 and the filter rods.

[0053] Specifically, in one embodiment, the turntable 10 is directly docked with the adapter tray 300. When the accommodating cavity 13 of the turntable 10 rotates to the discharge position 12, the bottom of the accommodating cavity 13 is suspended in the air, so that the material 200 automatically falls into the adapter tray 300. Of course, in other embodiments, a pushing mechanism can also be optionally provided at the discharge position 12 to push the material 200 in the accommodating cavity 13 into the adapter tray 300.

[0054] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
