AI Technical Summary
Existing compaction mechanisms are prone to causing sticking when the pressure roller comes into contact with the raised edge of the QR code, affecting the flatness and recognition accuracy of the QR code, and cannot compact it evenly, increasing the risk of it falling off.
An electric linear actuator drives the top plate to move downward, which in turn moves the deflector plate and connecting pin. The L-shaped slide plate causes the pressure roller to roll in the opposite direction, applying pressure from the center of the QR code to both sides. Combined with the spring rebound force, secondary compaction is achieved to ensure that the QR code is flat.
This effectively prevents the QR code edges from sticking to the pressure roller, reduces the risk of deformation and damage, ensures the QR code is flat, and improves the compaction effect and recognition accuracy.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of labeling devices, and in particular relates to a QR code compaction device for cigarette packaging boxes. Background Technology
[0002] With the continuous advancement of digital and intelligent transformation in the tobacco industry, cigarette packaging boxes (cigarette cartons) serve as a crucial carrier for product storage, transportation, and information traceability. Their surfaces are typically printed or affixed with QR codes. These QR codes record key information such as the production batch, quantity, and distribution route of the cigarettes inside. Therefore, ensuring that the QR codes on the cigarette cartons are firmly and smoothly affixed, avoiding issues such as curling, peeling, or blurred information, has become an indispensable part of the tobacco production line.
[0003] However, existing compaction mechanisms installed on production lines still have certain shortcomings in practical applications. During the compaction process of the pressure rollers in traditional compaction mechanisms, the raised edges of the QR codes are prone to sticking to the surface of the pressure rollers. This sticking not only causes the QR codes to be stretched, deformed, and damaged, affecting the accuracy of subsequent information recognition, but also prevents the compaction action from being applied evenly to the entire QR code, resulting in inadequate compaction in certain areas and further increasing the risk of QR code curling and falling off. Utility Model Content
[0004] The purpose of this invention is to provide a QR code compaction device for cigarette packaging boxes, which solves the problem that when the edge of the QR code on the cigarette box curls up in the existing compaction mechanism installed on the production line, the curled part is easy to stick to the compaction mechanism, affecting the compaction effect.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a QR code compaction device for cigarette packaging boxes, including a roller conveyor and a compaction mechanism. The compaction mechanism includes two symmetrical side plates, and trapezoidal grooves are opened on opposite sides of the two side plates. Two symmetrical L-shaped sliding plates are slidably fitted inside the trapezoidal grooves, and several pressure rollers are rotatably installed between the two L-shaped sliding plates on the same side.
[0007] The present invention is further configured such that two guide bolts are threadedly connected to the top of each of the two side plates, and a top plate is slidably fitted to the circumferential surfaces of the four guide bolts. A spring is sleeved on the circumferential surfaces of the guide bolts, and the spring is located between the top plate and the side plates.
[0008] The present invention is further configured such that two deflector plates are fixedly connected to the bottom of the top plate, the two deflector plates are respectively located above the two side plates, and two symmetrical inclined grooves are opened through one side of the deflector plate.
[0009] The present invention is further configured such that a connecting plate is fixedly connected to the top of the L-shaped sliding plate, and a connecting pin is fixedly installed on one side of the connecting plate, and the connecting pin slides in cooperation with the inclined groove.
[0010] The present invention is further configured such that a gantry frame is fixedly installed on the roller conveyor, and an electric linear actuator is fixedly installed on one side of the gantry frame, with the output end of the electric linear actuator being fixedly connected to the top plate.
[0011] The present invention is further configured such that a stop mechanism is fixedly installed at the bottom of the roller conveyor, and a polyurethane wrapping layer is sleeved on the circumferential side of the pressure roller.
[0012] This utility model has the following beneficial effects:
[0013] This invention uses an electric linear actuator to drive the top plate downwards, with a deflector plate moving synchronously with it. A connecting pin slides along an inclined groove and, via a connecting plate, drives an L-shaped sliding plate to move in the opposite direction along a trapezoidal groove, causing two sets of pressure rollers to roll in opposite directions, applying pressure from the center of the QR code towards the edges. During the upward movement of the top plate, the spring's rebound force causes the pressure rollers to roll in the opposite direction again, further completing a secondary compaction from the center to the sides. This directional compaction method effectively prevents the raised edges of the QR code from contacting the pressure rollers first, reducing the probability of the edges sticking to the roller surface due to uneven force, ensuring the QR code remains flat during compaction, and reducing the risk of being stretched, deformed, or damaged.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation
[0022] Please see Figure 1-3 This utility model is a QR code compaction device for cigarette packaging boxes, including a roller conveyor 1 and a compaction mechanism 2. The compaction mechanism 2 includes two symmetrical side plates 3, each with a trapezoidal groove 4 on one opposite side. Two symmetrical L-shaped sliding plates 5 are slidably fitted inside the trapezoidal groove 4. Several pressure rollers 6 are rotatably installed between the two L-shaped sliding plates 5 on the same side. The side plates 3 provide a mounting support frame for each component, and the trapezoidal groove 4 provides a sliding guide for the L-shaped sliding plates 5, ensuring that the L-shaped sliding plates 5 move along a specific trajectory. The L-shaped sliding plates 5 are used to install the pressure rollers 6, driving the pressure rollers 6 to move synchronously. The pressure rollers 6 directly contact the QR code on the cigarette box, and the compaction action is achieved by rolling.
[0023] Specifically, each of the two side plates 3 has two guide bolts 7 threadedly connected to its top. The four guide bolts 7 are slidably fitted with a top plate 8 on their circumference, which guides the vertical movement of the top plate 8 relative to the side plates 3. A spring 9 is fitted around the circumference of the guide bolts 7, and the spring 9 is located between the top plate 8 and the side plates 3.
[0024] Two deflector plates 10 are fixedly connected to the bottom of the top plate 8. The two deflector plates 10 are located above the two side plates 3 respectively. Two symmetrical inclined grooves 11 are opened through one side of the deflector plate 10. A connecting plate 12 is fixedly connected to the top of the L-shaped slide plate 5. A connecting pin 13 is fixedly installed on one side of the connecting plate 12. The connecting pin 13 slides with the inclined groove 11. When the deflector plate 10 moves synchronously with the top plate 8, the inclined groove 11 provides a sliding track for the connecting pin 13. The vertical movement of the top plate 8 is converted into the oblique sliding of the connecting pin 13 by the inclination angle of the inclined groove 11, realizing the change of movement direction and providing a power basis for the lateral movement of the L-shaped slide plate 5.
[0025] A gantry frame 14 is fixedly installed on the roller conveyor 1. An electric linear actuator 15 is fixedly installed on one side of the gantry frame 14. The output end of the electric linear actuator 15 is fixedly connected to the top plate 8. The electric linear actuator 15 serves as a power source and drives the top plate 8 to move up and down through the telescopic movement of its output end, providing driving force for the operation of the entire compaction mechanism 2. Its driving speed can be controlled to ensure that the compaction process proceeds smoothly.
[0026] A stop mechanism 16 is fixedly installed at the bottom of the roller conveyor 1. The sides of the pressure roller 6 are covered with a polyurethane coating. The stop mechanism 16 can intercept the cigarette box when it is conveyed to the compaction position. The polyurethane coating on the sides of the pressure roller 6 is elastic, which can increase the friction and contact pressure with the cigarette box, ensuring that the QR code is firmly attached, while avoiding damage to the surface of the cigarette box.
[0027] The operation process of this embodiment is as follows: When the cigarette box is conveyed to the preset compaction position on the roller conveyor 1, the stop mechanism 16 at the bottom of the roller conveyor 1 is activated to intercept the cigarette box. Subsequently, the electric linear actuator 15 installed on the gantry frame 14 starts to work, and its output end extends downward to drive the top plate 8 fixedly connected to it to move down, so that the compaction mechanism 2 moves down synchronously with the top plate 8 until the pressure roller 6 contacts the QR code area on the top surface of the cigarette box. When the pressure roller 6 contacts the top surface of the cigarette box, the side plate 3 and the pressure roller 6 stop due to the obstruction of the cigarette box. The downward movement stops, but the electric linear actuator 15 continues to push the top plate 8 downward. At this time, the top plate 8 compresses the spring 9 located between it and the side plate 3, and the spring 9 begins to store elastic potential energy. Simultaneously, the deflector plate 10 at the bottom of the top plate 8 moves downward with the top plate 8. At this time, the connecting pin 13 slides obliquely upward along the inclined groove 11. The sliding of the connecting pin 13 drives the L-shaped slide plate 5 to move to one side along the trapezoidal groove 4 on the side plate 3 through the connecting plate 12, so that the two L-shaped slide plates 5 located in the same trapezoidal groove 4 move in opposite directions, thereby driving the installed The two sets of pressure rollers 6 on the L-shaped slide plate 5 roll in opposite directions, thus compacting the QR code on the top surface of the cigarette box and ensuring that the QR code adheres firmly to the cigarette box. After the first compaction is completed, the electric linear actuator 15 drives the output end to retract upward, causing the top plate 8 to move upward. At this time, under the combined action of the spring force 9 and the weight of the pressure rollers 6 themselves, the pressure rollers 6 always maintain contact with the top surface of the cigarette box. At the same time, the top plate 8 drives the deflector plate 10 to move upward, and the connecting pin 13 slides diagonally downward along the inclined groove 11. The reverse sliding of the connecting pin 13 The L-shaped slide plate 5 is moved in the opposite direction along the trapezoidal groove 4 by the connecting plate 12 again, so that the two sets of pressure rollers 6 start to roll in the opposite direction, and the QR code on the top of the cigarette box is compacted again to further improve the adhesion of the QR code and prevent curling or falling off. After the second compaction is completed, the electric linear actuator 15 continues to drive the top plate 8 to move upward, so that the compaction mechanism 2 is separated from the top surface of the cigarette box. Then the stop mechanism 16 releases the obstruction to the cigarette box, and the cigarette box is transported to the next process under the action of the roller conveyor 1. The entire compaction operation is completed.
