Abstract
Description
Technical Field
[0001] This application relates to the field of cigarette packaging equipment technology, and more specifically, to a negative pressure smoke generation mechanism. Background Technology
[0002] In the logistics sorting and packaging process of the commercial tobacco industry, the cigarette cartons coming out of the sorting line enter the packaging machine. First, the cigarette cartons need to be sent to the stacking mechanism. The stacking mechanism usually stacks the cigarette cartons in a stacking pattern of 6 cartons * 6 layers or 5 cartons * 5 layers, and there are stacking patterns of 1 to 36 cartons. This requires that at least 1 carton and at most 6 cartons of cigarettes be sent into the stacking mechanism each time. However, the cigarette cartons conveyed from the sorting line are arranged closely together. This requires a mechanism that can send any number of cigarettes within 6 cartons into the stacking mechanism and prevent the subsequent cigarettes from entering.
[0003] Currently, the cigarette packs sold on the market include standard cigarettes, slim cigarettes, long and medium cigarettes, short cigarettes, and special-shaped cigarettes. The traditional cigarette dispensing method involves dividing the cigarette packs into three categories: standard cigarettes, slim cigarettes, and special-shaped cigarettes. These three categories are then fed into three separate stacking mechanisms, and the cigarettes from the three stacking mechanisms are combined into a single cigarette pack via a partition conveyor line. The dispensing mechanisms for standard and slim cigarettes consist of two belts moving at different speeds, plus two annular sponge belts above the belts, and can only dispense cigarette packs of specific thicknesses. The dispensing method for special-shaped cigarettes is usually a side-push method, which is less efficient. Currently, there is no dispensing mechanism that can accommodate all cigarette pack sizes and achieves a high dispensing speed.
[0004] Therefore, there is an urgent need for a smoking mechanism that can be compatible with various types of cigarette packaging and has a high smoking speed to improve the packaging speed of various types of cigarette packs. Utility Model Content
[0005] To address the aforementioned technical problems, this application provides a negative pressure smoke generation mechanism. By modifying different belt conveyor components in the prior art and setting a negative pressure vacuum chamber below the belt conveyor components, the cigarette packs are adsorbed, thereby achieving efficient conveying and matching of all types of cigarette packs.
[0006] The negative pressure smoke generating mechanism provided in this application has the following specific technical solution, including: a first conveyor belt assembly and a second conveyor belt assembly;
[0007] The first conveyor belt assembly and the second conveyor belt assembly are connected end to end at the same horizontal height in the conveying direction, and the first conveyor belt assembly and the second conveyor belt assembly are provided with their own drive components so that the synchronous belts have different conveying speeds;
[0008] The first conveyor belt assembly and the second conveyor belt assembly are provided with a plurality of adsorption holes on their surfaces, and a vacuum cavity communicating with the adsorption holes is provided below them.
[0009] Preferably, a blower is also provided, and the vacuum chamber is connected to the blower.
[0010] Preferably, one end of the blower is electrically connected to a frequency converter, which is installed below the first conveyor belt assembly and the second conveyor belt assembly.
[0011] Preferably, a support plate is also provided under the synchronous belt surface of the first conveyor belt assembly and the second conveyor belt assembly.
[0012] Preferably, the support plate is provided with slots corresponding to the adsorption holes, and the slots are arranged along the conveying direction.
[0013] Preferably, the slots and the adsorption holes are arranged in a group corresponding to each other in the opposite direction of the conveying, the first conveyor belt assembly and the second conveyor belt assembly are perpendicular to the conveying direction, and four groups of slots are provided on the support plate.
[0014] Preferably, the slots are evenly distributed perpendicular to the conveying direction, and the adsorption holes are evenly distributed along the conveying direction.
[0015] Preferably, the driving components for the first conveyor belt assembly and the second conveyor belt assembly are servo motors.
[0016] Preferably, the drive components of the first conveyor belt assembly and the second conveyor belt assembly are further provided with counting components.
[0017] Preferably, the first conveyor belt assembly and the second conveyor belt assembly are further connected to a control assembly for controlling the conveying and adsorption functions.
[0018] The negative pressure smoke generating mechanism provided by this utility model, by setting a negative pressure adsorption component on the traditional conveyor belt mechanism, can enable all types of cigarettes, including block cigarettes, to be fed into the cigarette stacking mechanism by the same smoke generating mechanism. The efficiency is basically the same as that of the standard cigarette smoke generating mechanism. After configuring the full-type cigarette stacking mechanism, there is no need to divide the cigarettes into several channels to enter the stacking mechanism, and there is no need for the subsequent order consolidation station, which greatly improves the overall efficiency of the packaging machine and the footprint of the equipment.

[0028] This utility model is written in a progressive manner in this specific embodiment.
[0029] This utility model embodiment provides a negative pressure smoke generating mechanism, which mainly includes: a first conveyor belt assembly 1 and a second conveyor belt assembly 2;
[0030] like Figure 1 and Figure 2 As shown, in this embodiment, similar to the smoke-generating mechanism in the prior art, the first conveyor belt assembly 1 and the second conveyor belt assembly 2 are both belt conveyor structures, and are connected end to end at the same horizontal height in the conveying direction. The first conveyor belt assembly 1 and the second conveyor belt assembly 2 are provided with their own drive components, so that the synchronous belts have different conveying speeds.
[0031] The surfaces of the first conveyor belt assembly 1 and the second conveyor belt assembly 2 are provided with a plurality of adsorption holes 3, and a vacuum cavity communicating with the adsorption holes 3 is provided below them.
[0032] Compared to the existing technology, the existing smoke-suppressing sponge belt above the conveyor belt is eliminated, and the conveyor belt is replaced with a synchronous belt with negative pressure adsorption holes 3. A vacuum chamber is set below the synchronous belt to provide negative pressure adsorption force.
[0033] By using the different conveying speeds of the two belts of the first conveyor belt assembly 1 and the second conveyor belt assembly 2, the gap between the cigarette packs is widened by the speed difference, and the number of cigarette packs entering the cigarette stacking mechanism is controlled. After a specified number of cigarette packs enter the cigarette stacking mechanism, the first conveyor belt assembly 1 and the second conveyor belt assembly 2 stop and instantly absorb the cigarette packs, providing suction force while preventing subsequent cigarette packs from slipping and flying into the cigarette stacking mechanism.
[0034] Preferably, the specific structure of the negative pressure smoke generating mechanism in this embodiment is further defined. In this embodiment, a blower is also provided, which is connected to the vacuum chamber. The blower generates negative pressure in the vacuum chamber through a large flow rate, so as to generate an adsorption force on the surfaces of the first conveyor belt assembly 1 and the second conveyor belt assembly 2.
[0035] Furthermore, in this embodiment, the specific structure of the blower is further defined. In this embodiment, one end of the blower is electrically connected to a frequency converter. The frequency converter is installed below the first conveyor belt assembly 1 and the second conveyor belt assembly 2. By providing the frequency converter, the flow rate of the blower can be adjusted, thereby adjusting the magnitude of the adsorption force generated on the surfaces of the first conveyor belt assembly 1 and the second conveyor belt assembly 2.
[0036] Preferably, in order to better support the cigarette sticks during transport, in this embodiment, a support plate 4 is also provided under the synchronous belt surface of the first conveyor belt assembly 1 and the second conveyor belt assembly 2 to support the bottom of the synchronous belt and avoid the situation where the synchronous belt is not supported enough due to the weight of the cigarette sticks, thus affecting the speed of the conveyor belt.
[0037] Furthermore, the structure of the support plate 4 in this embodiment is further defined. In this embodiment, in order to cooperate with the negative pressure adsorption of the adsorption hole 3, the support plate 4 is provided with a slot 5 corresponding to the adsorption hole 3. The slot 5 is arranged along the conveying direction to maintain communication with the vacuum chamber.
[0038] Furthermore, the structure of the slot 5 described in this embodiment is further defined. In this embodiment, the slot 5 and the adsorption hole 3 are set as a group in the opposite direction of the conveying. The first conveyor belt assembly 1 and the second conveyor belt assembly 2 are perpendicular to the conveying direction. Four groups of the slot 5 are provided on the support plate 4 to adsorb and convey the cigarette strips on the synchronous belt with a larger adsorption area.
[0039] Furthermore, the structure of the slot 5 described in this embodiment is further defined. In this embodiment, the slot 5 is evenly distributed perpendicular to the conveying direction, and the adsorption holes 3 are evenly distributed along the conveying direction to provide a more uniform negative pressure adsorption force to the cigarette stick and ensure stable conveying.
[0040] Preferably, in this embodiment, the driving components of the first conveyor belt assembly 1 and the second conveyor belt assembly 2 are specifically defined. In order to better control the conveying speed of the first conveyor belt assembly 1 and the second conveyor belt assembly 2, in this embodiment, the driving components of the first conveyor belt assembly 1 and the second conveyor belt assembly 2 are specifically servo motors 6, and are respectively set at one end for individual control.
[0041] As a preferred embodiment, the specific structure of the negative pressure smoke generating mechanism described in this embodiment is further defined. In this embodiment, the first conveyor belt assembly 1 and the second conveyor belt assembly 2 are also provided with counting components. The technical components are not specifically limited in this application, and can be counters such as photoelectric sensors and pressure sensors, used to record the number of smoke sticks.
[0042] Furthermore, the specific structure of the negative pressure smoke generating mechanism described in this embodiment is further defined. In this embodiment, the first conveyor belt assembly 1 and the second conveyor belt assembly 2 are also connected to a control component for controlling the conveying and adsorption functions. Specifically, key parameters of the specific conveying process, such as conveying speed and adsorption force, are digitally controlled. The control component can be a chip element such as a PLC or a programmable controller.
[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
