Description

Technical Field

[0001] This utility model relates to the field of code-code cigarette equipment technology, and more specifically to the field of code-code cigarette mechanism technology. Background Technology

[0002] Patent CN219971036U, entitled "Flipping and Receiving Mechanism for Stacking Cartons of Cigarettes and a Carton Stacking Production Line," discloses the following: a frame and a flipping mechanism, which includes a rotating mechanism, a rotating shaft, a guide plate, and a flipping plate. The rotating shaft has a radially penetrating sliding hole, and the flipping plate passes through the sliding hole. The guide plate is vertically positioned on the side of the flipping plate, and a guide groove is provided on the side of the guide plate facing the flipping plate. The guide groove has two ports located at the top and bottom of the rotating shaft, respectively. Sliding members are provided at both ends of the side of the flipping plate closest to the guide plate. During operation, the sliding members slide into the guide groove from the bottom port and slide out of the guide groove from the top port, and at least one of the two sliding members on one side is always located in the guide groove. When the flipping plate is in a horizontal state, the flipping plate extends to receive cartons of cigarettes. The carton stacking production line utilizes the flipping mechanism to stack cartons of cigarettes. This utility model has higher efficiency in cyclically receiving and stacking cartons of cigarettes.

[0003] However, the flipping cigarette receiving mechanism disclosed in the above patent has the following problems: the structure is complex and the manufacturing cost is high. In particular, the guide rail is easy to break, and the posture of the cigarette pack cannot be guaranteed, which leads to the cigarette stacks that are received later being scattered or disordered, or even damaging the cigarette packs. Utility Model Content

[0004] The purpose of this utility model is to provide a code cigarette mechanism and method in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] One aspect of this utility model provides a cigarette bar mechanism, including a cigarette inlet conveyor for conveying cigarette bars, a sensor-activated pressing and stopping mechanism disposed above the outlet of the cigarette inlet conveyor, a circulating cigarette receiving guide plate mechanism cooperating with the outlet of the cigarette inlet conveyor, an upper smoke baffle mechanism disposed above the circulating cigarette receiving guide plate mechanism and capable of reciprocating motion, and a height-adjustable dynamic cigarette receiving plate assembly disposed below the circulating cigarette receiving guide plate mechanism; the circulating cigarette receiving guide plate mechanism and the upper smoke baffle mechanism are controlled by a linkage drive mechanism.

[0007] Specifically, this solution uses a circulating smoke receiving system to improve efficiency. A circulating smoke blocking system ensures that the smoke is received and transported continuously from the moment it enters, maintaining the smoke's shape and achieving optimal smoke posture. The smoke receiving and blocking systems are powered by the same force to ensure synchronization. This structure is simple, efficient, and low-cost; all drive links can be achieved using ordinary chains.

[0008] In one embodiment, the circulating smoke receiving guide plate mechanism includes two circulating smoke receiving plate tracks arranged on both sides of the bottom of the smoke inlet conveyor along the conveying direction, two parallel smoke receiving ring chains arranged on both sides of the outlet of the smoke inlet conveyor along the conveying direction, and a first circulating smoke receiving plate and a second circulating smoke receiving plate installed between the two smoke receiving ring chains. The right ends of the first circulating smoke receiving plate are fixedly installed on the corresponding smoke receiving ring chains by positioning members, and the left ends of the first circulating smoke receiving plate are movably installed on the corresponding circulating smoke receiving plate tracks by guide members. The first circulating smoke receiving plate and the second circulating smoke receiving plate are staggered in the upper and lower layers during the operation of the smoke receiving ring chains.

[0009] The right sides of the second circulating smoke receiving plate are fixedly installed on the corresponding smoke receiving ring chain by positioning parts, and the left sides of the second circulating smoke receiving plate are movably installed on the corresponding circulating smoke receiving plate track by guide parts.

[0010] A rear fixing baffle for limiting the position is provided on the rear side of the smoke receiving ring chain, and a front smoke baffle is provided on the front section of the smoke receiving ring chain. The ring chain on the corresponding side is at the same height as the circulating smoke receiving plate track.

[0011] In one embodiment, the upper smoke baffle mechanism includes two smoke-blocking ring chains disposed on both sides above the outlet of the smoke inlet conveyor along the conveying direction, and a first smoke baffle and a second smoke baffle installed between the two smoke-blocking ring chains. The first smoke baffle and the second smoke baffle are alternately located in the upper and lower layers during the operation of the two smoke-blocking ring chains, and the lowest position of the first smoke baffle and the second smoke baffle is higher than the highest position of the first circulating smoke receiving plate and the second circulating smoke receiving plate.

[0012] In one embodiment, the two circulating smoke receiving plate tracks have the same structure and are symmetrically arranged. Each circulating smoke receiving plate track includes an upper horizontal track, a lower horizontal track, an inclined track, and a vertical track. The length of the upper horizontal track is greater than the length of the lower horizontal track, and the upper and lower horizontal tracks are aligned on the right. The lower end of the inclined track is connected to the left end of the lower horizontal track, and the upper end of the inclined track is connected to the upper horizontal track near the left end. The upper end of the inclined track is a certain distance away from the left end of the upper horizontal track.

[0013] In one embodiment, a unidirectional guiding component is provided at the connection between the upper end of the inclined track and the upper horizontal track. The unidirectional guiding component is an elastic self-weight transition piece, which is hinged to the channel at the connection between the upper end of the inclined track and the upper horizontal track.

[0014] In one embodiment, the system further includes a coordinated drive assembly, which comprises a smoke-blocking support gear system for tensioning two smoke-blocking ring chains, a smoke-receiving support gear system for tensioning two smoke-receiving ring chains, a common power drive gear system, and a coordinated belt. The linkage drive mechanism drives the common power drive gear system to rotate, and the coordinated belt bypasses the gears of the common power drive gear system, some gears of the smoke-blocking support gear system, and some gears of the smoke-receiving support gear system to achieve synchronous movement of the smoke-blocking ring chains and the smoke-receiving ring chains.

[0015] Specifically, because the cigarette receiving and blocking are synchronized, the entire process of the cigarette pack from entering to exiting the receiving plate forms a closed loop, preventing the cigarette pack from shifting and thus ensuring the cigarettes are not damaged.

[0016] In one embodiment, the sensing press-to-stop mechanism includes a counting sensor installed at the outlet of the smoke inlet conveyor, a smoke suppression cylinder located at the top of the outlet of the smoke inlet conveyor, and a pressure plate located at the end of the telescopic shaft at the bottom of the smoke suppression cylinder.

[0017] In one embodiment, the dynamic smoke receiving plate assembly includes a dynamic smoke receiving plate and a linear lifting mechanism disposed below the dynamic smoke receiving plate to control the raising and lowering of the dynamic smoke receiving plate.

[0018] In one embodiment, the linear lifting mechanism is one of a lifting cylinder assembly, a gear and rack drive assembly, a lifting electric cylinder assembly, a lifting electric lead screw assembly, or an electric lifting belt.

[0019] In one embodiment, the same power drive gear system includes a drive shaft and main drive teeth disposed at both ends of the drive shaft, and a main drive teeth and other gear tensioning and coordinating belt assembly.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model uses a circulating smoke receiving system to improve efficiency. The circulating smoke blocking system ensures that the smoke is received and transported from the inside out, maintaining the smoke's shape and achieving optimal smoke posture. The smoke receiving and blocking systems are powered by the same force, ensuring synchronization. This structure is simple, efficient, and low-cost.

[0022] 2. Because it is interconnected, the next layer can be completed at the same time as this layer, so as to achieve high efficiency, get as much code as possible, and minimize interruptions.

[0023] 3. The first and second circulating smoke receiving plates are powered at one end and unpowered at the other end as they move along the circulating smoke receiving plate track. When the first and second circulating smoke receiving plates pass the elastic self-weight transition plate, they automatically return to their original positions, allowing the first and second circulating smoke receiving plates to continue moving forward as transition plates, thus achieving single-head power circulation.

[0060] Example 7

[0061] This embodiment provides a process method for a cigarette bar coding mechanism, which uses the above-mentioned cigarette bar coding mechanism and includes the following steps:

[0062] S1. The smoke inlet conveyor 1 delivers a pack of cigarettes. When it reaches the first smoke baffle 11, the first smoke baffle 11 and the first circulating smoke receiving plate move forward simultaneously. When it reaches the current number of packs of cigarettes, the smoke suppressing cylinder presses down, and the smoke receiving plate and the smoke baffle move forward synchronously.

[0063] S2. When the first cycle smoke receiving plate 3 moves from the front to the rear fixed baffle 10, it continues to move downwards. The first cycle smoke baffle then moves downwards back. When the first cycle smoke receiving plate 3 moves down to the bottom, the dynamic smoke receiving plate 6 waits to receive smoke at about 5mm below it.

[0064] S3. As the first cycle of the cigarette receiving plate 3 moves back, the cigarettes are blocked by the front smoke baffle 5. The cigarettes are then scraped onto the dynamic cigarette receiving plate 6 one by one. After the dynamic cigarette receiving plate 6 finishes receiving the cigarettes, it moves down to the top of the first layer of cigarettes and is at the same height as the current cigarette receiving surface.

[0065] S4. The above is a loop. Since it is linked, the next layer can be completed at the same time when this layer is completed, so as to achieve high efficiency, and to get as much code as possible and minimize the pauses as much as possible.

[0066] S5. The first circulating smoke receiving plate 3 and the second circulating smoke receiving plate 7 are driven at one end and unpowered at the other end, moving along the circulating smoke receiving plate track 4. When the first circulating smoke receiving plate 3 and the second circulating smoke receiving plate 7 pass the elastic self-weight transition piece 2, they automatically return to their original positions, allowing the first circulating smoke receiving plate 3 and the second circulating smoke receiving plate 7 to continue moving forward as transition plates, thus realizing single-head power circulation.
