Description

Technical Field

[0001] This invention belongs to the tobacco industry and specifically relates to a cigarette filter rod and fastener arrangement device. Background Technology

[0002] The components in cigarette filters are primarily used in the filter portion of cigarettes. Their structure varies and may include a cylindrical outer shell, end faces, and internal filling materials. These components are designed to improve the taste of the smoke and reduce the intake of harmful substances. They can filter out some harmful substances in the smoke, such as tar and nicotine, and may also include flavorings or other ingredients to improve the taste of the smoke.

[0003] Typically, firmware is placed between two filter rods, but in a small number of cases, firmware is combined with a single filter rod. How to arrange the filter rods and firmware in an orderly manner is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a cigarette filter rod and fastener arrangement device that can arrange the filter rod and fastener in an orderly manner according to the interval setting.

[0005] This invention provides a cigarette filter rod and fastener arrangement device, comprising: A conveying mechanism for linearly conveying filter rods at intervals; A fastener arrangement mechanism includes a drum hopper, a dial assembly, a support, and a reciprocating pull assembly. One side of the dial assembly is rotatably connected to the support, and the other side is connected to the reciprocating pull assembly. The dial assembly is used to periodically deflect downwards, and as it deflects downwards, it transfers a fastener from the drum hopper onto itself. The dial assembly then transfers the fastener to a conveying mechanism, thus orderly arranging the filter rod and fasteners on the conveying mechanism. A gap-eliminating mechanism, which is connected to the conveying mechanism, is used to eliminate the gap between the filter rod and the fastener.

[0006] Optionally, the dial assembly includes a base, a rotating dial, and a rotating motor. The base has a receiving cavity and an opening near the conveying mechanism. The receiving cavity communicates with the opening. The rotating dial is disposed within the receiving cavity. The output shaft of the rotating motor is connected to the rotating dial. The edge of the rotating dial is provided with a plurality of circumferentially distributed teeth. The teeth are used to push the fasteners out of the drum hopper and transfer them to the conveying mechanism through the opening.

[0007] Optionally, the number of teeth arranged is 4-8, and they are evenly distributed circumferentially.

[0008] Optionally, the reciprocating pull assembly includes a drive motor, an eccentric cam mounted on the drive motor, a connecting plate mounted on the dial assembly, a rotating cam mounted on the connecting plate, and an elastic element; the eccentric cam is in contact with the circumferential surface of the rotating cam, and the rotation of the eccentric cam causes the rotating cam to move up and down periodically, and the elastic element is used to pull the dial assembly downward.

[0009] Optionally, the rotating cam is connected to a fastener, the fastener including a fastening stud that passes through and is screwed to the connecting plate and a fastening nut that is screwed to the fastening stud.

[0010] Optionally, the bottom end of the elastic element is connected to a connecting seat, and the bottom of the connecting seat is provided with a base.

[0011] Optionally, the drum hopper, support, and drive motor are fixedly mounted on the base plate.

[0012] Optionally, the conveying mechanism includes a guide frame, at least two synchronous pulleys disposed on the guide frame, a toothed belt connected to the synchronous pulleys for transmission, and a conveying motor for driving the synchronous pulleys; the toothed belt is evenly provided with toothed plates for pushing the filter rods.

[0013] Optionally, the gap elimination mechanism includes a fixed mounting frame, three gap elimination dial assemblies mounted on the fixed mounting frame, and a drive rotation assembly that drives the three gap elimination dial assemblies in linkage; the three gap elimination dial assemblies are arranged longitudinally and distributed in a triangular pattern, and the filter rod and the fastener on the conveying mechanism pass through the three gap elimination dial assemblies in sequence to eliminate the gap between the filter rod and the fastener.

[0014] Optionally, the backlash elimination dial assembly includes a guide plate and a backlash elimination dial component. An arc-shaped channel is formed between one side of the guide plate and the edge of the backlash elimination dial component for the filter rod and the fastener to pass through. The edge of the backlash elimination dial component is provided with a plurality of circumferentially distributed backlash elimination teeth.

[0015] The beneficial effect of this invention is that the fasteners are arranged in an orderly manner through the drum hopper and conveyed to the dial assembly. The dial assembly rotates the fasteners sequentially to a certain angle, feeding them into the conveying mechanism from the side. By setting the speed of the dial assembly and the conveying mechanism to match, the filter rods and fasteners are arranged at intervals on the conveying mechanism, thus being transported sequentially to the gap-eliminating mechanism. The gap-eliminating mechanism eliminates gaps between the filter rods and fasteners, and then the fasteners are conveyed to the forming cigarette machine to be rolled into filter tips. It should be noted that the difficulty in completing the above process lies in how to ensure that the drum hopper and the dial assembly do not interfere with each other during operation, while accurately transferring the fasteners with small mass and volume. The key to solving this problem is that the dial assembly can periodically deflect downwards on the support by the action of the reciprocating pulling component. During this stage, the dial assembly and the fasteners about to emerge from the drum hopper move downwards synchronously, thereby accurately transferring the fasteners to the dial assembly. Furthermore, the dial assembly also achieves the orderly arrangement of fasteners and filter rods on the conveying mechanism. Attached Figure Description

[0018] like Figure 1-5As shown, the present invention provides a cigarette filter rod and fastener arrangement device, comprising: a conveying mechanism 100, a fastener arrangement mechanism 200, and a gap-eliminating mechanism 300. The conveying mechanism 100 is used for linearly conveying the filter rod at intervals. The fastener arrangement mechanism 200 includes a drum hopper 210, a dial assembly 220, a support 230, and a reciprocating pull assembly 240. One side of the dial assembly 220 is rotatably connected to the support 230, and the other side is connected to the reciprocating pull assembly 240, used to pull the dial assembly 220 to periodically deflect downwards. Simultaneously with the downward deflection, the dial assembly 220 transfers a fastener from the drum hopper 210 to the dial assembly 220. The dial assembly 220 then transfers the fastener to the conveying mechanism 100, thus orderly arranging the filter rod and fastener on the conveying mechanism 100. The gap-eliminating mechanism 300 is connected to the conveying mechanism 100 to eliminate gaps between the filter rod and the fastener.

[0019] Compared with the prior art, the cigarette filter rod and fastener arrangement device provided by the present invention arranges the fasteners in an orderly manner through the drum hopper 210 and conveys them to the dial assembly 220. The dial assembly 220 rotates the fasteners to a certain angle in sequence, feeding the fasteners into the conveying mechanism 100 from the side. By setting the speed of the dial assembly 220 and the conveying mechanism 100 to match, the filter rod and fasteners are arranged at intervals on the conveying mechanism 100, so as to be transported in sequence to the gap elimination mechanism 300. The gap elimination mechanism 300 eliminates the gap between the filter rod and fasteners. Then, the fasteners are conveyed to the forming cigarette machine through the conveying mechanism 100 to be rolled into filter tips. It should be noted that the difficulty in completing the above process lies in how to ensure that the drum hopper 210 and the dial assembly 220 do not interfere with each other during operation, while accurately transferring the small-sized fasteners. The key to solving this problem is that the dial assembly 220 can be periodically deflected downward on the support 230 by the action of the reciprocating pulling component 240. During this stage, the dial assembly 220 and the fasteners about to emerge from the drum hopper 210 move downward synchronously, thereby accurately transferring the fasteners to the dial assembly 220. Furthermore, the dial assembly 220 also enables the fasteners and filter rods to be arranged in an orderly manner on the conveying mechanism 100.

[0020] In one embodiment, see Figure 2 and Figure 3The dial assembly 220 includes a base 221, a rotating dial 222, and a rotating motor 223. The base 221 has a receiving cavity 2211 and an opening 2212 near the conveying mechanism 100. The receiving cavity 2211 communicates with the opening 2212. The rotating dial 222 is disposed in the receiving cavity 2211. The output shaft of the rotating motor 223 is connected to the rotating dial 222. The edge of the rotating dial 222 is provided with a plurality of circumferentially distributed teeth 2221. The teeth 2221 are used to push the fastener out of the drum hopper 210 and transfer it to the conveying mechanism 100 through the opening 2212. Understandably, the base 221 is a square plate structure with a circular receiving cavity 2211 in the middle of the top. The rotating dial 222 is a circular disc, which is set in the receiving cavity 2211 and is rotatably connected to the base 221. The rotating motor 223 is suspended and fixedly installed at the bottom of the base 221 and can move with the base 221. The output shaft of the rotating motor 223 passes through and is connected to the rotating dial 222. Driven by the rotating motor 223, the rotating dial 222 rotates at a certain speed. The teeth 2221 are arranged to rotate the firmware by about 90° to the opening 2212 of the base 221, pushing the firmware out and smoothly falling onto the conveying mechanism 100. The rotating dial 222 and the side wall of the receiving cavity 2211 form an annular channel. The teeth 2221 are located in the annular channel to move the firmware along the annular channel.

[0021] In one embodiment, the number of teeth 2221 is 4-8 and they are evenly distributed circumferentially; preferably, the number of teeth 2221 is 6, so that when one tooth 2221 moves the firmware out of the drum hopper 210, the preceding tooth 2221 moves the preceding firmware to the opening 2212.

[0022] In one embodiment, see Figure 3 and Figure 4The reciprocating pull assembly 240 includes a drive motor 241, an eccentric cam 242 mounted on the drive motor 241, a connecting plate 243 mounted on the dial assembly 220, a rotating cam 244 mounted on the connecting plate 243, and an elastic element 245. The eccentric cam 242 is in contact with the circumferential surface of the rotating cam 244, and the rotation of the eccentric cam 242 causes the rotating cam 244 to move up and down periodically. The elastic element 245 is used to pull the dial assembly 220 downward. Understandably, the edge of the eccentric cam 242 has a large radius on one side and a small radius on the other, with a rounded transition between the two parts. The small radius part of the eccentric cam 242 engages with the rotating cam 244, and the dial assembly 220 is in its highest position and almost horizontal. This state is short-lived, and the arranged teeth 2221 do not engage with the drum hopper 210. When the eccentric cam 242 passes the small radius part, under the action of the elastic element 245, the side of the dial assembly 220 closest to the eccentric cam 242 away from the support 230 gradually deflects downward. At this time, the arranged teeth 2221 just contact the fastener at the outlet of the drum hopper 210. As the fastener is driven downward by the drum hopper 210, the arranged teeth 2221 also move downward and push the fastener out of the drum hopper 210. Subsequently, the eccentric cam 242 moves to the large radius part, and the dial assembly 220 gradually returns to an almost horizontal state. This process is repeated to orderly transfer the fastener to the conveying mechanism 100.

[0023] In one embodiment, see Figure 4 To facilitate the installation and disassembly of the rotating cam 244, the following solution is provided: a fastener 246 is connected to the rotating cam 244, the fastener 246 including a fastening stud that passes through and is screwed to the connecting plate 243 and a fastening nut that is screwed to the fastening stud. It is understood that the rotating cam 244 is pre-rotated rotatably connected to the fastening stud on a fixed axis. During installation, the fastening stud is inserted through the connecting plate 243, and then the fastening nut is tightened. Disassembly is performed in the reverse manner.

[0024] In one embodiment, to facilitate the installation and removal of the elastic element 245, a connecting seat 247 is connected to the bottom end of the elastic element 245, and a base is provided at the bottom of the connecting seat 247. Preferably, the elastic element 245 is a spring.

[0025] In one embodiment, the drum hopper 210, the support 230, and the drive motor 241 are fixedly mounted on the base plate 250. In this way, the drum hopper 210, the support 230, and the drum hopper 210 can be assembled into a single module, which facilitates transportation and assembly with other components.

[0026] In one embodiment, see Figure 1The conveying mechanism 100 includes a guide frame 110, at least two synchronous pulleys 120 disposed on the guide frame 110, a toothed belt 130 driven by the synchronous pulleys 120, and a conveying motor (not shown) for driving the synchronous pulleys 120. The toothed belt 130 has evenly distributed toothed plates for pushing the filter rods. It is understood that the guide frame 110 has a straight configuration with a guide groove in the middle for the toothed belt 130 to pass through and for mounting necessary drive rollers to support the toothed belt 130. The synchronous pulleys 120 are determined according to the length of the guide frame 110, and at least one synchronous pulley 120 is driven by the conveying motor. The toothed belt 130 is a conveyor belt with multiple evenly distributed toothed plates for pushing the filter rods and fasteners.

[0027] In one embodiment, see Figure 1 The gap-eliminating mechanism 300 includes a fixed mounting frame 310, three gap-eliminating dial assemblies 320 mounted on the fixed mounting frame 310, and a drive rotation assembly 330 that drives the three gap-eliminating dial assemblies 320 in linkage. The three gap-eliminating dial assemblies 320 are arranged longitudinally and distributed in a triangular pattern. The filter rods and fasteners on the conveying mechanism 100 pass through the three gap-eliminating dial assemblies 320 in sequence to eliminate the gaps between the filter rods and fasteners. Specifically, the gap-eliminating dial assembly 320 includes a guide plate 322 and a gap-eliminating dial component 321. An arc-shaped channel is formed between one side of the guide plate 322 and the edge of the gap-eliminating dial component 321 for the filter rods and fasteners to pass through. The edge of the gap-eliminating dial component 321 is provided with a plurality of circumferentially distributed gap-eliminating teeth. The gap elimination mechanism 300 uses existing technology. The working principle is briefly described below without going into too much detail. As you can understand, the filter rods and fasteners in the gap elimination disc are sequentially transferred to the gap elimination conveying channel. By controlling the rotation speed of the three gap elimination dials 321, the gap between the filter rods and fasteners is eliminated, ensuring that there are no gaps between the filter rods and fasteners in the gap elimination conveying channel, thus preparing them for subsequent entry into the forming cigarette machine.

[0028] In one embodiment, the drum hopper 210 includes a hopper body 211, a drum disc 212, and a drum motor 213, all fixedly mounted on a base plate 250. The hopper body 211 has a flat cavity for accommodating fasteners. The thickness of the cavity is slightly greater than the length of the fasteners, allowing the fasteners to be neatly stacked within the hopper body 211. The drum motor 213 drives the drum disc 212 to rotate. The toothed grooves on the edge of the drum disc 212 can accommodate one fastener, and the edge of the drum disc 212 and the hopper body 211 have an arc-shaped guide channel that allows only a single row of fasteners to pass through. As the drum disc 212 rotates, it moves the fasteners to the outlet of the hopper body 211, where they enter the dial assembly 220 under the action of the stop block 2111.
