Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packing, in particular to a cigarette dispensing device and a packing machine. Background Art

[0002] With the development of the tobacco industry, cigarette carton sizes and categories are increasing. Existing cigarette carton dispensers use independent high- and low-speed belt units, requiring the addition of transition plates. For example, Chinese utility model patent CN212314830U discloses a cigarette carton counting and conveying device, which includes a low-speed conveyor belt, a high-speed conveyor belt, a negative pressure suction device, and a counting device. The output end of the low-speed conveyor belt connects to the input end of the high-speed conveyor belt via a transition plate. Due to the resistance and flatness of the transition plate, as well as the poor connection between the two belt loops, cigarette carton transitions can cause problems such as jumping, skewing, and uncontrollable speed changes, thus affecting the stability of back-end sorting.

DETAILED DESCRIPTION

[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0031] Example 1:

[0032] To accommodate a wider range of cigarette product specifications with a single packaging machine and address sorting issues such as cigarette tilt and misaligned cigarette stops caused by belt slippage during startup and shutdown, this embodiment provides a cigarette dispensing device that utilizes a belt drive coupled with vacuum adsorption to ensure no lost steps during startup and no overshoot during shutdown. Furthermore, the conveyor belts utilize a cross-distribution design for smooth and reliable transitions. The conveyor belts can be synchronous belts, flat belts, O-belts, or other types of conveyor belts, which are not limited in this application.

[0033] Specifically, such as Figure 1-Figure 3 As shown, the cigarette dispensing device of this embodiment includes a frame 1, a first conveyor belt group, a second conveyor belt group, an elastic cigarette pressing mechanism, etc. The first and second conveyor belt groups are mounted on a support frame 2 and arranged sequentially along the conveying direction of the cigarettes 16; the support frame 2 is mounted on the upper side of the frame 1. The first conveyor belt group is in a low-speed range, and the second conveyor belt group is in a high-speed range. The cigarettes 16 are transported from the low-speed range to the high-speed range.

[0034] like Figure 1 and Figure 3 As shown, an elastic cigarette pressing mechanism is provided above the first conveyor belt group and the second conveyor belt group, respectively. A set gap is formed between the elastic cigarette pressing mechanism and the conveying surface of the first conveyor belt group or the second conveyor belt group. The elastic cigarette pressing mechanism is a flexible brush cigarette pressing mechanism, which includes a circulation mechanism. The circulation mechanism is a roller, and the flexible brush can be a hair brush, a silicone brush, or the like. In this embodiment, there are two flexible brushes 6. The installation direction of the flexible brush 6 is parallel to the conveying surface of the cigarette strip 16 and perpendicular to the conveying direction. There is a certain interval between the two flexible brushes 6. When the cigarette strip 16 passes through the flexible brush 6, the rows of hair brushes act as scrapers, which can straighten the cigarette posture, facilitate the counting and detection of the rear-end photoelectric system, and reduce problems such as cigarette jamming, cigarette following, and photoelectric counting errors.

[0035] It can be understood that in other embodiments, the elastic smoke pressing mechanism can also be a sponge smoke pressing mechanism. The sponge smoke pressing mechanism is a prior art and will not be described in detail here.

[0036] like Figure 2 As shown, the first conveyor belt group includes multiple first conveyor belts 3 arranged in parallel, and the second conveyor belt group includes multiple second conveyor belts 4 arranged in parallel; that is, multiple first conveyor belts 3 and second conveyor belts 4 are evenly distributed in the transverse direction (perpendicular to the conveying direction of the cigarette strips 16). The first conveyor belts 3 and the second conveyor belts 4 are staggered in the transverse direction, and are cross-arranged at the junction of the high-speed section and the low-speed section. This cross-arrangement is achieved through the following structure:

[0037] The transmission pulley at the output end of the first conveyor belt 3 and the transmission pulley at the input end of the second conveyor belt 4 are installed on the same transmission shaft, so that the second conveyor belt 4 and the first conveyor belt 3 have overlapping sections, forming a cross-transition structure, which makes the transition of the cigarette strips 16 smoother, avoiding various problems that affect the system sorting, such as the cigarette strips 16 being pulled slantingly due to poor belt docking at the joints of the previous structure, and the cigarette strips 16 jumping due to uneven transition plates.

[0038] It should be noted that the cross arrangement of the first conveyor belt 3 and the second conveyor belt 4 can be a single conveyor belt cross structure or a multiple conveyor belt cross structure.

[0039] It should be noted that the first conveyor belt 3 and the second conveyor belt 4 of this embodiment are both synchronous belts. "First", "second" and "third" are only distinctions for the convenience of description and do not impose any restrictions on the structure of the synchronous belts themselves.

[0040] Each first conveyor belt 3 is connected to the same first drive mechanism to achieve synchronous movement of the first conveyor belt 3; similarly, each second conveyor belt 4 is connected to the same second drive mechanism. The first drive mechanism and the second drive mechanism of this embodiment adopt the same structure, both being implemented by a motor and a transmission mechanism connected to the motor; the transmission mechanism can be a belt drive mechanism, a chain drive mechanism, etc. Of course, each first conveyor belt 3 and each second conveyor belt 4 can be connected to the same third drive mechanism, and differential movement of the first and second conveyor belts can be achieved by setting different transmission ratios.

[0041] The first conveyor belt 3 and the second conveyor belt 4 are tightened by the tightening mechanism 12. Figure 7 As shown, the tensioning mechanism 12 includes a mounting seat 14 and a tensioning wheel 13 connected to the mounting seat 14; the mounting seat 14 corresponding to the first conveyor belt group (second conveyor belt group) is connected to the mounting plate 15, and the mounting plate 15 is connected to the support frame 2 by bolts.

[0042] The first conveyor belt group and the second conveyor belt group are respectively provided with a vacuum chamber 5 inside. Figure 4 As shown, a sealing cover 7 is installed on the top of the vacuum chamber 5. The sealing cover 7 cooperates with the first conveyor belt 3 and the second conveyor belt 4 through a guide sealing structure. Compared with the structure of a whole flat belt combined with a sealed chamber, the air leakage rate is reduced. Specifically, the sealing cover 7 is provided with a plurality of protrusions 8. The protrusions 8 are arranged along the length direction of the conveyor belt and correspond one to one with the conveyor belt; a guide groove 11 is provided on the inner surface of the corresponding conveyor belt to cooperate with the protrusion 8. The protrusion 8 is inserted into the guide groove 11. The two form a guide sealing structure, which plays a role in limiting the conveyor belt. It can avoid a series of problems such as the conveyor belt running off during vacuum adsorption, losing steps when the conveyor belt starts, and slipping and overshooting when the conveyor belt stops, thereby ensuring the stable transportation of the cigarette strips 16.

[0043] like Figure 4 and Figure 5 As shown, multiple protrusions are evenly distributed along the two edges of the inner surface of the conveyor belt, forming a guide groove 11 between the two groups of protrusions. Adsorption grooves 10 are provided on the outer surface of the conveyor belt at positions corresponding to the guide grooves 11, with multiple adsorption grooves 10 evenly distributed along the length of the conveyor belt. Evenly distributed second adsorption holes 9 are provided on the raised portion 8. These second adsorption holes 9 cooperate with the adsorption grooves 10 to achieve vacuum adsorption of the conveyor belt.

[0044] In this embodiment, if Figure 6 As shown, the first conveyor belt 3 (the second conveyor belt 4) is provided with a first adsorption hole 17. In order to increase the contact area with the cigarette, the first conveyor belt 3 (the second conveyor belt 4) is further provided with an adsorption groove 10. The adsorption groove 10 is a sunken notch structure, which is composed of an expansion structure connected to the first adsorption hole 17 that passes through the first conveyor belt 3 (the second conveyor belt 4). The expansion structure is a strip groove structure formed by the first adsorption hole 17 on the top surface of the first conveyor belt 3 (the second conveyor belt 4); and, as shown Figure 4 As shown, the second adsorption holes 9 are also arranged in a strip shape, which increases the adsorption area of ​​the conveyor belt and the cigarette strips 16 without increasing the air leakage rate, improves the adsorption force of the vacuum adsorption, and realizes the stable transmission of the cigarette strips 16.

[0045] It is understandable that in other embodiments, the second adsorption hole 9 can also be configured to be columnar or in other shapes.

[0046] It is understandable that in other embodiments, the protrusion 8 may be provided on the inner surface of the conveyor belt, and the sealing cover 7 may be provided with a corresponding guide groove 11 , and the guide groove 11 does not pass through the sealing cover 7 .

[0047] This embodiment replaces the traditional entire belt structure with a parallel conveyor belt, so that a single packaging machine is compatible with more cigarette cartons 16 specifications and can distribute cigarette cartons of all specifications; and the conveyor belt and the sealing cover 7 are matched with each other through a guide sealing structure, and adsorption grooves 10 and second adsorption holes 9 are correspondingly provided to ensure the stability of transportation without increasing the air leakage rate; at the same time, the structure of conveyor belt transmission + vacuum adsorption ensures that the distribution device does not lose steps when starting and does not overshoot when stopping.

[0049] This embodiment provides a cigarette carton packaging machine, including the cigarette carton dispensing device described in Example 1.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
