Description

Technical Field

[0001] This invention relates to the field of tobacco processing equipment, and more specifically, to a staggered wheel and a parallel wheel for feeding short tobacco sticks, and a short tobacco stick feeding device. Background Technology

[0002] The heated cigarette making unit consists of two parts: a cigarette rod forming machine and a filter tip machine. Currently, this type of equipment uses either the traditional cigarette rolling process or a reverse-rolling process to produce finished heated cigarettes. When the length of the cigarette rod in the rolling specifications is between 50mm and 75mm, the rotational linear speed of the "spider hand" is close to the running linear speed of the cigarette stick. The spider hand is relatively stationary when picking up the cigarette, ensuring a seamless hand-to-hand contact without cigarette dropping. If the rolled cigarette rod is less than 50mm long, the spider hand will slide relative to the cigarette stick, causing cigarette dropping. Additionally, in the reverse-rolling process, the cigarette supply mechanism of the heated cigarette equipment uses a smoke-dispensing wheel and a smoke-catching wheel to receive long cigarette rods from upstream. This application also has a minimum cigarette rod length limitation, requiring the receiving of long cigarette rods first, followed by cutting, staggering, and paralleling to achieve the supply of a single row of short cigarette rods.

[0003] To enable stable online production of short cigarettes by the cigarette stick forming machine and the mouthpiece machine, invention patent CN214103204U discloses a cigarette feeding mechanism for short cigarettes. This mechanism uses a small rubbing plate suspended at the outer position of the misalignment wheel to rub the short cigarette stick, causing it to roll to the adjacent circumferential support groove to complete the misalignment. However, this misalignment method has the drawback of damaging the short cigarette stick. Invention patent CN218551258 discloses a parallel mechanism for cutting and misaligning rod-shaped materials. This mechanism uses an eccentric misalignment structure for the misalignment wheel and a cam-slider parallel structure for the parallel wheel. Although it overcomes the drawback of damaging the short cigarette stick and can solve the problem of stable online production of the cigarette stick forming machine and the mouthpiece machine under the heating and back-rubbing process, the design of the misalignment wheel and parallel wheel of this mechanism is relatively complex, resulting in a higher equipment failure rate. Summary of the Invention

[0004] To better solve the problem of short cigarette bar supply, improve the stability of cigarette bar misalignment and parallel operation during the supply process, simplify the equipment structure, improve product quality, and reduce equipment failure rate, the technical solution adopted in this invention is as follows:

[0005] A short cigarette stick supply device includes a transmission box and a cigarette receiving wheel, a conveying wheel, a cutting wheel, a staggered wheel, a parallel wheel and a converging wheel connected in sequence on one side of the transmission box. The cigarette receiving wheel, the conveying wheel, the cutting wheel, the staggered wheel, the parallel wheel and the converging wheel are respectively provided with a plurality of stick-bearing grooves, and each stick-bearing groove is provided with a first negative pressure suction hole.

[0006] The cutting wheel is used to cut the long cigarette stick into two short cigarette sticks side by side. The staggered wheel is used to arrange the two rows of short cigarette sticks in a staggered manner. The parallel wheel is used to arrange the two staggered rows of short cigarette sticks into a single row of short cigarette sticks. The merging wheel is used to splice the two rows of mouthpieces and the single row of short cigarette sticks into a cigarette combination of "single long mouthpiece + short cigarette stick + single long mouthpiece".

[0007] The misaligned wheel includes a guide device, an inner misaligned wheel body, and an outer misaligned wheel body arranged coaxially. The guide device is used to misalign the two rows of short cigarette sticks according to the difference in the distance they fall. The outer circumferential surface of the inner misaligned wheel body and the outer circumferential surface of the outer misaligned wheel body are respectively provided with the rod-bearing groove. The rod-bearing groove on the inner misaligned wheel body is misaligned with the rod-bearing groove on the outer misaligned wheel body. The inner misaligned wheel body is used to grab the inner short cigarette sticks, and the outer misaligned wheel body is used to grab the outer short cigarette sticks.

[0008] Based on the above, in order to achieve staggered arrangement, the guiding device includes an inner fixed guide and an outer fixed guide arranged side by side, an inner movable guide is provided below the inner fixed guide, and an outer movable guide is provided below the outer fixed guide.

[0009] An inner gap is formed between the lower end of the inner fixed guide and the upper end of the inner movable guide, and an outer gap is formed between the lower end of the outer fixed guide and the upper end of the outer movable guide. The inner gap and the outer gap are misaligned.

[0010] The inner gap is used to intercept the short cigarette stick on the inner side from the phase where the left end face of the inner movable guide is located and wait for it to be grabbed by the inner misaligned wheel.

[0011] The outer gap is used to intercept the short cigarette stick on the outside from the phase where the left end face of the outer movable guide is located, and wait for it to be grabbed by the outer misaligned wheel.

[0012] Based on the above, the inner fixed guide and the outer fixed guide are respectively arc-shaped guides coaxial with the cutting wheel; the inner movable guide and the outer movable guide are respectively arc-shaped guides coaxial with the misaligned wheel.

[0013] Based on the above, in order to achieve parallel arrangement, the parallel wheel includes an intermediate wheel, and air distribution rings are provided at both ends of the intermediate wheel. The air distribution rings are provided with a second negative pressure suction hole that connects to the bearing groove on the parallel wheel.

[0014] Each valve train has a positioning ring on its inner side, and two positioning rings are provided with baffles at intervals corresponding to the bearing grooves on the parallel wheels. Each valve train has a retaining ring on its outer side, and two retaining rings are provided with notches at intervals corresponding to the bearing grooves on the parallel wheels. The baffles are all provided on the positioning rings that are far away from the notches.

[0015] The outer periphery of the parallel wheel is provided with a negative pressure cover. The negative pressure cover, together with the rod support groove of the parallel wheel, the air distribution ring, and the baffle ring, forms a negative pressure driving air chamber channel with one end connected to the atmosphere and the other end connected to the second negative pressure suction hole. The negative pressure driving air chamber channel is used to create a pressure difference at both ends of the short cigarette rod, causing the short cigarette rod to slide along the rod support groove of the parallel wheel toward the second negative pressure suction hole until it is blocked by the baffle.

[0016] Based on the above, in order to clean the cut seam in a timely manner, a cutter and a cut seam cleaning mechanism are provided on one side of the cutting wheel.

[0017] Based on the above, in order to facilitate centering and transfer, a centering adjustment mechanism is provided on one side of the conveying wheel. The centering adjustment mechanism is used to correct the symmetrical arrangement of the long tobacco rods along the center of the cutting wheel.

[0018] The present invention also provides a staggered wheel for supplying short cigarette sticks, comprising a guide device, an inner staggered wheel body and an outer staggered wheel body arranged coaxially. The guide device is used to stagger two rows of short cigarette sticks according to the difference in sliding distance. The outer peripheral surfaces of the inner staggered wheel body and the outer peripheral surfaces of the outer staggered wheel body are respectively provided with rod-bearing grooves. The rod-bearing grooves on the inner staggered wheel body and the rod-bearing grooves on the outer staggered wheel body are staggered. The inner staggered wheel body is used to grip the inner short cigarette sticks, and the outer staggered wheel body is used to grip the outer short cigarette sticks.

[0019] The guiding device includes an inner fixed guide and an outer fixed guide arranged side by side. An inner movable guide is provided below the inner fixed guide, and an outer movable guide is provided below the outer fixed guide.

[0020] An inner gap is formed between the lower end of the inner fixed guide and the upper end of the inner movable guide, and an outer gap is formed between the lower end of the outer fixed guide and the upper end of the outer movable guide. The inner gap and the outer gap are misaligned.

[0021] The inner gap is used to intercept the short cigarette stick on the inner side from the phase where the left end face of the inner movable guide is located, and wait for it to be grabbed by the inner misaligned wheel.

[0022] The outer gap is used to intercept the short cigarette stick on the outside from the phase where the left end face of the outer movable guide is located, and wait for it to be grabbed by the outer misaligned wheel.

[0023] The present invention also provides a parallel wheel for supplying short cigarette sticks, including an intermediate wheel with a rod-bearing groove, and air distribution rings at both ends of the intermediate wheel, wherein the air distribution rings are provided with negative pressure suction holes that communicate with the rod-bearing grooves on the intermediate wheel.

[0024] Each valve train has a positioning ring on its inner side, and two positioning rings are provided with baffles at intervals corresponding to the bearing grooves on the intermediate wheel. Each valve train has a retaining ring on its outer side, and two retaining rings are provided with notches at intervals corresponding to the bearing grooves on the intermediate wheel. The baffles are all provided on the positioning rings away from the notches.

[0025] The outer periphery of the intermediate wheel, the air distribution ring, and the positioning ring is provided with a negative pressure cover. The negative pressure cover, together with the rod support groove of the intermediate wheel, the air distribution ring, and the baffle ring, forms a negative pressure driving air chamber channel with one end connected to the atmosphere and the other end connected to the negative pressure suction hole. The negative pressure driving air chamber channel is used to create a pressure difference at both ends of the short cigarette rod, causing the short cigarette rod to slide along the rod support groove of the intermediate wheel toward the negative pressure suction hole until it is blocked by the baffle.

[0026] The misaligned wheel is also equipped with a pair of fixed frames. One fixed frame is used to install the inner fixed guide and the outer fixed guide, while the other fixed frame is used to adjustably install the inner movable guide and the outer movable guide. The inner movable guide and the outer movable guide can be adjusted in a set direction.

[0027] The negative pressure cover is an arc-shaped flexible plate coaxial with the parallel wheels. The two retaining rings are classified as inner and outer retaining rings according to their position. The inner retaining ring has a connecting notch every other parallel wheel's support groove, and the outer retaining ring also has a notch every other parallel wheel's support groove. The notches on the inner and outer retaining rings are not located on the same parallel wheel's support groove.

[0028] The two positioning rings can be divided into an inner positioning ring and an outer positioning ring according to their positions. A baffle is provided on the inner positioning ring every other parallel wheel bearing groove, and a baffle is also provided on the outer positioning ring every other parallel wheel bearing groove. The baffles on the inner positioning ring and the baffles on the outer positioning ring are not located in the same parallel wheel bearing groove. Furthermore, all the baffles are located on the positioning rings furthest from the notch.

[0029] This invention possesses significant substantive features and substantial advancements compared to existing technologies. Specifically, the short cigarette stick supply device provides a relatively advanced staggered wheel and parallel wheel structure. After the long cigarette stick is cut, the inner and outer short cigarette sticks are respectively conveyed to the gap phase and remain there, awaiting being grasped by the inner and outer staggered wheels, thereby achieving staggered positioning of the short cigarette sticks. This staggered positioning method is more stable than rubbing staggered positioning and can significantly reduce damage to the short cigarette sticks and cigarette drop. The parallel wheels, through the rod-bearing groove and the negative pressure cover, form a negative pressure driving air chamber channel for the short cigarette sticks to slide. This allows the inner and outer short cigarette sticks to slide outward and inward respectively, achieving parallel movement. This parallel method is highly efficient and causes less damage to the cigarette tip. This short cigarette stick supply device can stably improve product quality and reduce equipment failure rate.

[0030] Finally, the short cigarette stick supply device provided by this invention adds a cutting step to the original cigarette supply mechanism, followed by staggered and parallel cutting to provide a single row of short cigarette sticks. This ensures that the cigarette sticks are smoothly grasped by the spider hand, avoiding cigarette drop at the spider hand. This device is also suitable for applications using a cigarette-catching wheel to receive long cigarette sticks, comprehensively solving the problem of integrated production between the cigarette stick forming machine and the mouthpiece machine.

[0039] Example 1

[0040] This embodiment provides a short cigarette stick supply device, such as... Figure 1 As shown, the system includes a transmission box 24, a power unit, and a transmission device. A smoke-receiving wheel 1, a conveying wheel 2, a cutting wheel 3, a staggered wheel 4, a parallel wheel 5, and a converging wheel 6 are sequentially connected to one side of the transmission box. Each of the smoke-receiving wheel, the conveying wheel, the cutting wheel, the staggered wheel, the parallel wheel, and the converging wheel has several rod-supporting grooves, and each rod-supporting groove has a first negative pressure suction hole. The power unit and transmission device are existing technology and will not be described in detail here.

[0041] like Figure 1 and Figure 2 As shown, the long cigarette rod 7 rotates and is conveyed by the receiving wheel 1, conveying wheel 2, cutting wheel 3, misaligning wheel 4, parallel wheel 5, and converging wheel 6, while simultaneously completing the centering, cutting, misalignment, and paralleling of the long cigarette rod 7, ultimately forming a single row of short cigarette rods 8 that merge with the mouthpiece rods 9 spaced a certain distance apart to form a cigarette combination.

[0042] The conveying wheel 2 is correspondingly arranged with the receiving wheel 1 and is used to receive the long tobacco sticks conveyed by the receiving wheel. A first centering adjustment mechanism 10 is provided on one side of the conveying wheel. The first centering adjustment mechanism 10 is used to correct the long tobacco sticks 7 so that the long tobacco sticks are symmetrically arranged along the cutting center.

[0043] The cutting wheel 3 is positioned opposite the conveying wheel 2 and is used to cut a long tobacco stick into two short tobacco sticks of equal length. The cutting wheel is also equipped with a kerf cleaning mechanism 11 and a cutter 12, which work together to cut the long tobacco stick and clean the kerf. The conveying wheel 2, cutting wheel 3, converging wheel 6, first centering adjustment mechanism 10, kerf cleaning mechanism 11, and cutter 12 are all existing technologies and structures, and will not be described in detail here.

[0044] Specifically, such as Figure 3 and Figure 4As shown, the misaligned wheel 4 and the cutting wheel 3 are arranged opposite to each other. The misaligned wheel 4 includes an inner misaligned wheel body 13 and an outer misaligned wheel body 14. The flue boxes of the two wheels are installed at a set angle to form the basic structure of the misaligned wheel. A guide device 23 installed on a fixed frame is provided between the cutting wheel 3 and the misaligned wheel 4.

[0045] The guiding device 23 includes an inner fixed guide member 15 and an outer fixed guide member 16 arranged side by side. An inner movable guide member 17 is connected below the inner fixed guide member 15. An outer movable guide member 18 is connected below the outer fixed guide member 16. The inner misaligned wheel 13 is arranged corresponding to the inner fixed guide member 15 and the inner movable guide member 17. The outer misaligned wheel 14 is arranged corresponding to the outer fixed guide member 16 and the outer movable guide member 18.

[0046] The inner movable guide 17 and the outer movable guide 18 can be adjusted in a set direction. The right end face of the inner movable guide 17 and the left end face of the inner fixed guide 15 are adjusted to a set gap, and the right end face of the outer movable guide 18 and the left end face of the outer fixed guide 16 are adjusted to a set gap. This allows the inner short cigarette stick to be retrieved at the phase where the left end face of the inner movable guide is located, and to remain in the gap, waiting to be grasped by the inner misaligned wheel. The outer short cigarette stick is retrieved at the phase where the left end face of the outer movable guide is located, and to remain in the gap, waiting to be grasped by the outer misaligned wheel. Two rows of short cigarette sticks are formed on the misaligned wheel, with a front-to-back misalignment, completing the misalignment.

[0047] Specifically, the inner fixed guide 15 and the outer fixed guide 16 are arc-shaped guides coaxial with the cutting wheel 3, allowing the short cigarette stick in the rod-bearing groove of the cutting wheel to rotate with the cutting wheel. The inner movable guide 17 and the outer movable guide 18 are arc-shaped guides coaxial with the misaligned wheel 4, allowing the short cigarette stick to rotate with the misaligned wheel after being gripped by it.

[0048] like Figure 3 , Figure 5 and Figure 6 As shown, the bearing groove of the parallel wheel 5 is designed as a deep "V" shape. Air distribution rings 21 are provided at both ends of the parallel wheel, two positioning rings 20 are embedded in the middle, and a guide rail 19 is mounted on it. Specifically, a negative pressure cover 22 is mounted on the guide rail 19. For ease of illustration, the negative pressure cover is only shown on the diagram. Figure 3 The display shows that, Figure 5 , Figure 6 The details have been hidden.

[0049] The parallel wheel includes an intermediate wheel 29, and air distribution rings 21 are provided at both ends of the intermediate wheel 29. The air distribution rings 21 are provided with a second negative pressure suction hole that connects to the bearing groove on the parallel wheel.

[0050] Each valve train 21 has a positioning ring 20 on its inner side, and two positioning rings 20 are provided with baffles 28 at intervals corresponding to the bearing grooves on the parallel wheels. Each valve train 21 has a retaining ring 27 on its outer side, and two retaining rings 27 are provided with notches at intervals corresponding to the bearing grooves on the parallel wheels. The baffles 28 are all provided on the positioning rings away from the notches.

[0051] A negative pressure cover 22 is provided around the outer periphery of the parallel wheel via a guide rail 19. The negative pressure cover 22, together with the rod support groove of the parallel wheel, the air distribution ring 21, and the baffle ring 27, forms a negative pressure driving air chamber channel with one end connected to the atmosphere and the other end connected to the second negative pressure suction hole. The negative pressure driving air chamber channel is used to create a pressure difference between the two ends of the short cigarette rod, causing the short cigarette rod to slide along the rod support groove of the parallel wheel towards the second negative pressure suction hole until it is blocked by the baffle.

[0052] After the parallel wheel receives the double-row short smoke rods from the misaligned wheel, when the short smoke rods 8 enter the indexing area covered by the negative pressure hood, they slide along the rod-bearing groove of the parallel wheel towards the second negative pressure suction hole until they are blocked by the positioning ring. Through this method, the inner and outer rows of short smoke rods slide outwards and inwards respectively, achieving parallel movement.

[0053] The converging wheel 6 receives two rows of mouthpieces 9 with a certain spacing from the mouthpiece supply system and a single row of short cigarette sticks 8 from the parallel wheel, forming a cigarette combination of "single-length mouthpiece + short cigarette stick + single-length mouthpiece". This solves the problem of supplying short cigarette sticks and enables the online production of the cigarette stick forming machine and the mouthpiece connecting machine.

The specific structure differs from that of Embodiment 1 in that, in this embodiment: Figure 7 As shown, a smoke-catching wheel 25 is used instead of the smoke-receiving wheel 1 and the conveying wheel 2 in Embodiment 1. The smoke-catching wheel 25 is used to receive and convey the long smoke rods. In this embodiment, a second centering adjustment mechanism 26 is provided on one side of the cutting wheel. The second centering adjustment mechanism 26 is used to correct the symmetrical arrangement of the long smoke rods along the center of the cutting wheel.
