Description

Technical Field

[0001] This utility model relates to the field of cigarette sorting and packaging, specifically to a device for preventing cigarettes from falling off during the wrapping and sealing process of a stack of cigarettes. Background Technology

[0002] Currently, in the national cigarette logistics sorting and distribution centers, the vast majority of cigarette sorting and stacking packaging modes are still based on the following: standard cigarettes, slim cigarettes, and medium cigarettes are sorted, consolidated, and packaged on the main sorting line using high-speed cigarette sorting machines, while non-standard cigarettes and irregularly shaped cigarettes are sorted, consolidated, and packaged on separate sorting lines composed of dedicated sorting equipment. Finally, the cigarette packs from the two lines are delivered offline after the contract is signed. Although a small number of cigarette logistics and distribution centers have implemented a "one pack of cigarettes" sorting model, the equipment stability is not high. In particular, during the sealing and cutting packaging process, the cigarettes fall apart, causing damage to the sealing and cutting blades and frequent malfunctions that severely impact the overall sorting efficiency. The main reason for this is that after implementing "one pack of cigarettes" sorting, the cigarettes in the order stacks are of various specifications and sizes. When the stacks of cigarettes enter the centering, pressing, and sealing stage, the pressing mechanism cannot hold down all the cigarettes on the top layer of the stack. When the sealing and cutting film moves downwards to seal, it pulls the cigarettes on the top layer of the stack that were not held down by the pressing mechanism, causing the cigarettes to fall below the sealing and cutting blades and resulting in damage. Even with detection switches for protection, the frequent occurrence of similar situations leads to frequent equipment malfunctions, seriously affecting the equipment's packaging efficiency. Therefore, it is crucial to prevent cigarettes from falling apart during the sealing and cutting packaging process, which would damage the sealing and cutting blades and cause frequent equipment shutdowns, thus affecting the operational stability and sorting efficiency of the sorting system. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a device to prevent cigarette packs from falling off during the wrapping and sealing process, thereby preventing cigarette packs from scattering or falling off during the wrapping and sealing process and improving the stability and efficiency of the sorting system.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a device for preventing cigarettes from falling off during the wrapping and sealing process of stacked cigarettes, comprising a frame, a first stacked cigarette conveyor installed in the middle of the frame, a second stacked cigarette conveyor connected to the front end of the first stacked cigarette conveyor, a stacked cigarette transplanting mechanism at the rear end of the first stacked cigarette conveyor, a film-wrapping mechanism at the upper end, a film-cutting mechanism between the first stacked cigarette conveyor and the second stacked cigarette conveyor, stacked cigarette centering and shaping mechanisms on both sides of the second stacked cigarette conveyor, and a cigarette-pressing mechanism at the upper end; the cigarette-pressing mechanism includes a main cylinder support plate and a three-position five-way solenoid valve installed on the frame, a main cylinder installed in the middle of the main cylinder support plate, the rod end of the main cylinder connected to a transmission support plate, a plurality of cigarette-pressing cylinders provided on the transmission support plate, each cigarette-pressing cylinder having a cigarette-pressing plate connected to its rod end, a check valve installed on the main cylinder, the check valve being connected to the three-position five-way solenoid valve via an air circuit, and a pressure regulating valve installed on the cigarette-pressing cylinder.

[0005] The main cylinder support plate is equipped with linear bearings at both ends, and the guide rod passes through the linear bearings to connect with the transmission support plate.

[0006] The plurality of smoke-pressing cylinders are arranged at equal intervals along the transverse direction of the transmission support plate.

[0007] The smoke-pressing plate is bonded with a smoke-pressing sponge.

[0008] The first stack of tobacco conveyor and the sealing and cutting mechanism are equipped with detection switches.

[0009] The beneficial effects of this utility model are:

[0010] 1. Multiple pressing plates are used to press each row of cigarettes on the stack, which effectively prevents the cigarettes that are not pressed by the pressing mechanism from shifting or falling when the sealing and cutting mechanism is activated, because the specifications of the top layer of cigarettes in the order stack are different.

[0011] 2. The piston rod of the smoke-pressing cylinder is initially in the extended state. After the smoke is pressed, the piston rod is retracted by the upward reaction force of the smoke stack, so as to achieve flexible smoke pressing. The internal pressure of the smoke-pressing cylinder can be adjusted by the pressure regulating valve according to the actual working conditions to ensure the compaction of the smoke stack.

[0012] 3. The main cylinder adopts a check valve combined with a three-position five-way solenoid valve to form a closed air circuit control loop. It can press the cigarette pressing plate down to a certain position in advance according to the number of cigarettes in the order, which can effectively save the pressing plate pressing time, improve the sealing and packaging efficiency, and at the same time effectively avoid the safety problem of the entire cigarette pressing mechanism falling down in the event of a sudden power failure.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0020] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example

[0021] like Figures 1 to 4As shown, this utility model discloses a device for preventing cigarettes from falling off during the wrapping and sealing process of stacked cigarettes. It includes a frame 1, a first stacking cigarette conveyor 2 installed in the middle of the frame 1, a second stacking cigarette conveyor 3 connected to the front end of the first stacking cigarette conveyor 2, a stacking cigarette transplanting mechanism 4 at the rear end of the first stacking cigarette conveyor 2, a film-wrapping mechanism 5 at the upper end, a sealing and cutting mechanism 6 between the first stacking cigarette conveyor 2 and the second stacking cigarette conveyor 3, stacking cigarette centering and shaping mechanisms 7 on both sides of the second stacking cigarette conveyor 3, and a cigarette-pressing mechanism 8 at the upper end. The cigarette-pressing mechanism… The 8 includes a main cylinder support plate 801 and a three-position five-way solenoid valve 8011 mounted on the frame 1. A main cylinder 802 is mounted in the middle of the main cylinder support plate 801. The rod end of the main cylinder 802 is connected to a transmission support plate 803. The transmission support plate 803 is equipped with several smoke-pressing cylinders 804, each smoke-pressing cylinder 804 having a smoke-pressing plate 805 connected to its rod end. A check valve 806 is mounted on the main cylinder 802, and the check valve 806 is connected to the three-position five-way solenoid valve 8011 via an air circuit. A pressure regulating valve 807 is mounted on each smoke-pressing cylinder 804. The several smoke-pressing cylinders 804 are equidistantly arranged along the transverse direction of the transmission support plate 803. Detection switches are provided on the first stacked smoke conveyor 2 and the sealing and cutting film mechanism 6.

[0022] When pressing down the tobacco stack, the piston rod of the main cylinder 802 extends, causing the transmission support plate 803 to move downwards, which in turn drives the pressing cylinder 804 to move downwards synchronously. The piston rod of the pressing cylinder 804 is in the extended state. When the pressing plate 805 contacts the tobacco pack and presses down a certain distance, the tobacco stack exerts a reaction force on the pressing plate 805, causing the piston rod of the pressing cylinder 804 to retract. At this time, the pressing cylinder 804 functions like a spring, thus achieving the function of flexible pressing. To ensure compaction of the tobacco stack, the pressure regulating valve 807 can be used to adjust the internal pressure of the pressing cylinder 804 according to the actual working conditions. Multiple pressing cylinders can also be used... The cigarette pressing plate 805 presses down each row of cigarettes on the stack, effectively preventing the cigarettes not pressed down by the pressing mechanism from shifting or falling when the sealing and cutting mechanism 6 operates, especially when the specifications of the top layer of cigarettes in the order stack are different. The main cylinder 802 can form a closed air circuit control loop by using the check valve 806 and the three-position five-way solenoid valve 8011. It can press down the pressing plate 805 to a certain position in advance according to the number of cigarettes in the order stack, which can effectively save the pressing time of the pressing plate 805, improve the sealing and cutting packaging efficiency, and at the same time effectively prevent the entire pressing mechanism 8 from falling down in the event of a sudden power failure, thus avoiding safety problems.

[0023] Furthermore, in order to ensure the stability of the downward smoke-pressing movement, linear bearings 808 are provided at both ends of the main cylinder support plate 801, and the guide rod 809 passes through the linear bearings 808 and is connected to the transmission support plate 803.

[0024] Furthermore, in order not to damage the cigarette packs, the cigarette pressing plate 805 is bonded with a cigarette pressing sponge 8010.

[0025] Working principle: When the order stack of cigarettes is conveyed to the cigarette packing mechanism 4 by the first stack of cigarettes conveyor 2, the stack of cigarettes conveyor 4 pushes the stack of cigarettes to the film covering mechanism 5. The film covering mechanism 5 works with the stack of cigarettes conveyor 4 to cover the stack of cigarettes with film. When the stack of cigarettes is completely pushed onto the second stack of cigarettes conveyor 3 and the detection switch detects the stack of cigarettes, the stack of cigarettes centering and shaping mechanism 7 performs the stack of cigarettes centering and shaping action. The pressing mechanism 8 moves downward to press down the top layer of cigarettes in the stack of cigarettes. When the detection switch located below the sealing and cutting mechanism 6 does not detect any cigarettes, the sealing and cutting mechanism 6 moves downward and works with the pressing mechanism 8 and the stack of cigarettes centering and shaping mechanism 7 to complete the film sealing and cutting packaging work, so that the order stack of cigarettes becomes a semi-finished cigarette pack, and the second stack of cigarettes conveyor 3 continues to convey the cigarette pack to the subsequent process section.

[0026] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
