Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging coding technology, and in particular to a tobacco packaging coding positioning device. Background Technology

[0002] In the tobacco production process, coding of cigarette cartons is a core step in achieving product traceability, monopoly management, and anti-counterfeiting. Currently, production lines generally use conveyor belts to transport cartons of cigarettes to coding machines, where laser or ink is used to complete the coding operation. However, as the cigarettes travel on the conveyor belt to the coding machine, their unpredictable movement results in different coding positions for each carton. This makes inspection inconvenient, as locating the coding position is difficult, significantly impacting inspection efficiency.

[0003] Existing technologies employ linear fully constrained guides, which, in conjunction with baffles, provide good positioning. However, this requires precise alignment during feeding (as exemplified by a tobacco packaging coding and positioning device with prior art publication number CN221163686U, which utilizes this type of positioning technology). This places significant demands on manual or mechanical feeding. Manual feeding reduces feeding efficiency, while automatic feeding equipment requires an additional vision positioning system, increasing mechanical costs. Furthermore, the use of linear fully constrained guides increases the wear rate of the cigarette packaging film and the frequency of equipment jamming due to the guide mechanism constantly contacting both sides of the cigarette pack.

[0004] Therefore, a tobacco packaging coding and positioning device is proposed. Utility Model Content

[0005] This utility model is a tobacco packaging coding and positioning device proposed to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tobacco packaging coding and positioning device, comprising a coding machine body, a belt conveyor fixedly installed on the worktable of the coding machine body, and an industrial control integrated computer fixedly installed on the column of the coding machine body. The belt conveyor is symmetrically provided with side plates on both sides, and the side plates are fixedly installed on the worktable of the coding machine body. A cylinder is fixedly installed on one side of the outer surface of each of the two side plates. The movable ends of the two cylinders are provided through the side plates and are fixedly connected to pressure detection components. The detection ends of the two pressure detection components are fixedly installed with slides.

[0007] Both sides of the outer surface of the two slides are fixedly connected to a first bearing seat that extends into the interior. The inner rings of the bearings built into the two adjacent first bearing seats are fixedly connected to a spline sleeve. An electric shaft is installed between the two spline sleeves and the two side plates.

[0008] Both spline sleeves are connected to an adjacent slide block by a common transmission assembly, and the two transmission assemblies are arranged in a mirror image.

[0009] The bottom of each of the two slides is symmetrically rotatably connected to two synchronous pulleys, and the transmission assembly is connected to the adjacent synchronous pulleys;

[0010] The bottom of each of the two slides is equipped with an adjustable tension wheel, and each of the two adjustable tension wheels is engaged with a synchronous belt between two adjacent synchronous pulleys. The outer surface of each of the two synchronous belts is fixedly fitted with a rubber belt.

[0011] Two photoelectric detection components are symmetrically mounted on one side of the outer surface of a single side plate.

[0012] Preferably, a guide rod is fixedly connected between the two side plates, and the two slide blocks are slidably sleeved on the outer surface of the guide rod. The guide rod ensures that the slide blocks maintain linear motion during movement.

[0013] Preferably, both pressure detection components include a mounting base, and the mounting base is fixedly connected to the movable end of the cylinder. A pressure sensor is fixedly embedded in the mounting base on one side of the slide, and the detection end of the pressure sensor is fixedly connected to the slide. The pressure sensor monitors the clamping force in real time to avoid damage to the cigarette pack due to excessive clamping force.

[0014] Preferably, the electric shaft includes a servo motor, which is fixedly mounted on one side of the outer surface of the side plate. The drive end of the servo motor is fixedly connected to a spline shaft, which passes through both side plates and is rotatably connected to both side plates. Both spline sleeves are slidably fitted onto the outer surface of the spline shaft. The cooperation between the spline shaft and the spline sleeves ensures the stability of power transmission and allows the slide to move freely.

[0015] Preferably, both of the photoelectric detection components include a crossbar, and the crossbar is fixedly connected to the adjacent side plate. A photoelectric sensor is fixedly installed on one side of the bottom of the crossbar, and the photoelectric sensor is located above the belt conveyor. The photoelectric sensor accurately detects the position of the cigarette pack, triggers the clamping and coding actions, and reduces human intervention.

[0016] Preferably, the industrial control all-in-one computer is electrically connected to the coding machine body, belt conveyor, cylinder, pressure sensor, and servo motor. The industrial control all-in-one computer centrally controls the coordinated operation of each component to ensure accurate action timing and reduce misoperation.

[0017] Preferably, both of the transmission components include a first bevel gear, which is fixedly sleeved on the outer surface of the spline sleeve. A second bevel gear is meshed with the bottom of the first bevel gear, and a long shaft is fixedly connected to the bottom of the second bevel gear. The long shaft is fixedly connected to the adjacent synchronous pulley. The bevel gear transmission structure is compact and has high transmission efficiency, ensuring that power is smoothly transmitted to the synchronous pulley.

[0018] Preferably, two second bearing seats are symmetrically fixedly embedded at the bottom of each of the two slides, and the inner ring of the bearing built into the second bearing seat is fixedly connected to the mounting shaft of the synchronous pulley. The second bearing seat supports the rotation of the synchronous pulley and reduces frictional resistance.

[0019] Preferably, both adjustable tensioning pulleys include a slide groove, which is fixedly installed at the bottom of the slide block. The top side of the slide groove is provided with an anti-slip block, and the bottom of the anti-slip block is fixedly connected with a bolt. A locking pin is threaded onto the outer surface of the bolt, and the outer surface of the locking pin is rotatably connected to the tensioning pulley body. The tensioning pulley body meshes with the synchronous belt. The adjustable tensioning pulley facilitates the adjustment of the tension of the synchronous belt, ensuring the transmission effect.

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

[0021] In use, this utility model is a tobacco packaging coding and positioning device that uses a cylinder to drive a sliding block and a rubber belt to dynamically clamp the cigarette pack. The photoelectric detection component triggers the positioning action in real time, eliminating the need for strict alignment during manual or mechanical feeding. This solves the problem of accurate alignment required by existing linear fully constrained guides, improving feeding efficiency and avoiding the cost of additional visual positioning systems.

[0022] In use, this utility model provides a tobacco packaging coding and positioning device that uses a rubber belt to dynamically clamp the cigarette pack, contacting only both sides of the cigarette pack during the coding stage. Compared with the rigid baffles in the prior art that are in continuous contact, this significantly reduces the wear rate of the packaging film, while also reducing the risk of mechanical jamming and improving the stability of equipment operation.

[0033] like Figures 1 to 6As shown, a tobacco packaging coding and positioning device is disclosed, comprising a coding machine body 1, a belt conveyor 7 fixedly installed on the worktable of the coding machine body 1, and an industrial control integrated computer 3 fixedly installed on the column of the coding machine body 1.

The pressure sensor 11 is used for force measurement, and its model is ZCB511E-W.

[0034] Both sides of the outer surface of the two slide blocks 6 are fixedly connected to the first bearing seats 16 that extend into the interior. The inner rings of the bearings built into the two adjacent first bearing seats 16 are fixedly connected to the spline sleeves 17. The two spline sleeves 17 and the two side plates 2 are jointly installed with an electric shaft. The electric shaft includes a servo motor 8, and the servo motor 8 is fixedly installed on one side of the outer surface of the side plate 2. The drive end of the servo motor 8 is fixedly connected to a spline shaft 9, and the spline shaft 9 is set through the two side plates 2 and is rotatably connected to the two side plates 2. Both spline sleeves 17 are slidably sleeved on the outer surface of the spline shaft 9. The spline shaft 9 and the side plate 2 are rotatably connected through the bearing seats. The seat of the bearing seat is fixedly connected to the side plate 2, and the inner ring of the bearing built into the bearing seat is fixedly connected to the spline shaft 9.

[0035] Both spline sleeves 17 are connected to adjacent slides 6 with a transmission assembly, and the two transmission assemblies are mirror images of each other. The bottom of each slide 6 is symmetrically connected to two synchronous pulleys 13, and the transmission assembly is connected to the adjacent synchronous pulley 13. Both transmission assemblies include a first bevel gear 20, which is fixedly sleeved on the outer surface of the spline sleeve 17. The bottom of the first bevel gear 20 is meshed with a second bevel gear 22. The bottom of the second bevel gear 22 is fixedly connected to a long shaft 19, which is fixedly connected to the adjacent synchronous pulley 13. The bottom of each slide 6 is symmetrically fixedly fitted with two second bearing seats 21, and the inner ring of the bearing inside the second bearing seat 21 is fixedly connected to the mounting shaft of the synchronous pulley 13.

[0036] Both slide blocks 6 are equipped with adjustable tensioning pulleys at their bottoms. Both adjustable tensioning pulleys are engaged with two adjacent synchronous pulleys 13 and connected to a synchronous belt 14. The outer surfaces of both synchronous belts 14 are fixedly fitted with rubber belts 18. Both adjustable tensioning pulleys include a groove 23, which is fixedly installed at the bottom of the slide block 6. The top side of the groove 23 is provided with an anti-slip block 24. The bottom of the anti-slip block 24 is fixedly connected with a bolt 26. The outer surface of the bolt 26 is threaded with a locking pin 25.

The top of the locking pin 25 and the bottom of the anti-slip block 24 are provided with anti-slip textures to increase the locking effect with the top and bottom of the groove 23 during locking and to prevent slippage.

[0037] Two photoelectric detection components are symmetrically installed on one side of the outer surface of a single side plate 2.

A photoelectric sensor 5 is fixedly installed on the bottom side of the crossbar 4, and the photoelectric sensor 5 is located above the belt conveyor 7. The photoelectric sensor 5 is used to detect the position of the cigarette pack, and its model is selected from the E3ZK series.

[0038] The industrial control all-in-one computer 3 is electrically connected to the coding machine body 1, belt conveyor 7, cylinder 10, pressure sensor 11, and servo motor 8 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in combination with common knowledge.

[0039] Working principle: First, loosen bolt 26, then move locking pin 25. Locking pin 25 drives tension wheel body 15 to move, adjusting the tension of synchronous belt 14. Then tighten bolt 26. Anti-slip block 24, in conjunction with locking pin 25, fixes tension wheel body 15 in a suitable position on slide groove 23. Next, start belt conveyor 7, servo motor 8, and coding machine body 1. Servo motor 8 drives spline shaft 9 to rotate and transmits power to transmission components through spline sleeve 17. When the cigarette pack is placed on belt conveyor 7, the conveyor transports it forward. When the cigarette pack passes the first photoelectric sensor 5, photoelectric sensor 5 detects a signal and transmits it to industrial control computer 3. Industrial control computer 3 then controls the cylinders 10 on both sides to push slide 6 along guide rod 12 towards the center, causing rubber belt 18 to move closer to the cigarette pack. When the slide block 6 moves, the spline sleeve 17 slides on the spline shaft 9 to ensure that the transmission is not affected. At the same time, the first bevel gear 20 drives the second bevel gear 22 to rotate, which in turn drives the synchronous pulley 13 to rotate through the long shaft 19. The synchronous belt 14 maintains appropriate tension under the action of the adjustable tensioner to ensure stable operation of the synchronous belt 14. The rubber belt 18 rotates under the drive of the synchronous belt 14 and contacts the cigarette packs to apply clamping force. The pressure sensor 11 monitors the clamping force in real time. If the pressure is too high, the industrial control integrated computer 3 will adjust the stroke of the cylinder 10 to avoid damaging the cigarette packs.

[0040] When the cigarette pack continues to be conveyed to the second photoelectric sensor 5, the industrial control unit 3 controls the servo motor 8 and belt conveyor 7 to stop running, the spline shaft 9 stops rotating, and the rubber belt 18 remains stationary to ensure accurate positioning of the cigarette pack. At this time, the coding machine body 1 performs a coding operation on the cigarette pack. After coding is completed, the industrial control unit 3 controls the cylinder 10 to retract, the slide 6 to reset, the rubber belt 18 to release the cigarette pack, and the belt conveyor 7 to restart, sending out the coded cigarette pack. At the same time, the servo motor 8 resumes operation, preparing for the next cycle.
