Description

Technical Field

[0001] This invention relates to the field of cigarette box cardboard processing and manufacturing technology, specifically to a conveying and feeding device for cigarette box hot stamping production. Background Technology

[0002] Existing conveying devices for hot-stamped cigarette boxes mostly employ mechanical contact-based straightening structures, such as rigid side baffles for compression and correction or pressure plates for conveying. These structures easily lead to wear and scratches on the hot-stamped layer of the cigarette box cardboard. While some existing technologies use air-floating conveying, these are mostly stable air cushions formed by unidirectional air holes, which can only achieve suspension and cannot assist in posture adjustment. Furthermore, they lack effective flow guidance and stabilization structures, resulting in insufficient straightening accuracy. This is especially problematic for thin cigarette box cardboard, which is prone to warping and shifting. In the unloading and collection stage, existing automatic straightening devices mostly rely on additional power sources such as cylinders and motors to drive the side baffles. This not only consumes a lot of energy but also cannot adaptively adjust the straightening force according to the amount of cigarette boxes stacked, resulting in poor adaptability. In some scenarios, manual assistance is still required for straightening, leading to low efficiency. Summary of the Invention

[0003] To address this issue, the present invention provides a conveying and feeding device for hot stamping cigarette boxes, thereby overcoming the problems of the prior art.

[0004] This invention is implemented by the following technical solution:

[0005] The conveying and feeding straightening device in cigarette box hot stamping production includes a conveying device for straightening and stabilizing the cigarette box cardboard posture, and a collecting device for automatically feeding and straightening the cigarette box cardboard. The output end of the conveying device is fixedly connected to the input end of the collecting device. The conveying device achieves precise straightening of the cigarette box cardboard posture through a combination of undulating air cushions, stepped flow guidance, and ultrasonic radiation pressure. The collecting device achieves automatic straightening of the feeding by gravity adaptive drive side straightening. After being straightened and conveyed by the conveying device, the hot-stamped cigarette box cardboard enters the collecting device for automatic straightening and collection.

[0006] Preferably, the conveying device includes a conveyor belt, a limiting component, a conveying alignment component, and a supporting frame. The conveyor belt is mounted on the supporting frame, and a drive motor is fixed on the supporting frame. The output shaft of the drive motor is fixedly connected to the drive roller of the conveyor belt to drive the conveyor belt to rotate. The limiting component is fixed on the supporting frame and located between the input end of the conveyor belt and the conveying alignment component. The conveying alignment component is fixed on the supporting frame and located downstream of the limiting component.

[0007] Preferably, the limiting component includes two limiting plates arranged opposite each other, the two limiting plates are attached to both sides of the conveying surface of the conveyor belt, and multiple arc-shaped rubber blocks are evenly distributed on the opposite sides of the two limiting plates.

[0008] Preferably, the conveying alignment component includes a cover, a stepped flow guide component, a flow stabilizer, an air outlet component, a pressing component, and an ultrasonic transducer. The cover is a rectangular cover structure with openings at both ends, fixed on a support frame and covering the conveying surface of the conveyor belt. The stepped flow guide component is provided with multiple sets of flow guide modules in sequence along the conveying direction. Each set of flow guide modules includes multiple vertical plates fixed at equal intervals to the inner side wall of the cover. The distance between two adjacent sets of flow guide modules gradually decreases along the conveying direction.

[0009] Preferably, the flow stabilizer is fixed on the support frame and located at the lower end of the conveying surface of the conveyor belt. The input end is connected to a circulating air guide pipe with a valve. Multiple air outlet components are spaced apart on the conveying surface of the conveyor belt along the conveying direction. Each air outlet component includes two rows of inclined air guide holes with opposite inclination directions. The two rows of inclined air guide holes are inclined in the conveying direction and the reverse conveying direction, respectively. The airflow of the flow stabilizer forms a undulating air cushion through the air outlet components. The ultrasonic transducer is fixed on the inner top surface of the enclosure in the form of multiple rows of ultrasonic transducer groups. The center line of each row of ultrasonic transducer groups coincides with the center line of the gap between the two groups of flow guide modules, and the length of each row of ultrasonic transducer groups is adapted to the gap length.

[0010] Preferably, the clamping assembly includes a fixed frame, a T-shaped positioning rod, a roller frame, a roller, and a clamping compression spring. The fixed frame is fixed to the side of the support frame, the T-shaped positioning rod slides through the fixed frame, the roller frame is fixed to the bottom of the T-shaped positioning rod, the roller is rotatably mounted on the roller frame, and the clamping compression spring is located on the outside of the T-shaped positioning rod, with both ends fixed between the fixed frame and the roller frame and always in a compressed state to continuously apply pressure toward the conveyor belt to the roller.

[0011] Preferably, the collecting device includes a placement plate, a side alignment component, a positioning plate, an elastic support component, and a swing component. The input side of the placement plate is in close contact with the output surface of the conveyor belt, and the top surface is an inclined structure that slopes downward from the input side to the output side. The side alignment component is symmetrically arranged on both sides of the placement plate, and the side alignment component includes two opposing side alignment blocks, a limiting sliding member, and a linkage component.

[0012] Preferably, the linkage assembly includes a push block, a top rod frame, a lever, a sliding block, and a slide groove. One side of the push block is an inclined surface, which is in surface contact with the lower end of the inclined surface of the side alignment block. The inclination angle of both inclined surfaces is 45 degrees, forming a 1:1 transmission ratio. The bottom surface of the push block is fixedly connected to the top end of the top rod frame. The bottom end of the top rod frame is hinged to one end of the lever. The middle part of the lever is hinged to a hinge seat fixed on the mounting frame. The other end of the lever is hinged to the sliding block. The slide groove is fixed to the bottom surface of the placement plate. The sliding block of the side alignment assembly fits into the slide groove and can slide along the length of the slide groove.

[0013] Preferably, the limiting sliding component includes a limiting sliding protrusion and a limiting sliding groove. The limiting sliding protrusion is fixed to the outer wall of the side-mounted block, and the limiting sliding groove is fixed to the side of the placement plate. The limiting sliding protrusion is fitted into the limiting sliding groove and can slide along the limiting sliding groove. The elastic support assembly is fixed to the bottom surface of the placement plate. The elastic support assembly includes a support sleeve, a support rod, and a support compression spring. The support sleeve is fixed to the bottom surface of the placement plate and sleeved on the outside of the support rod. The support compression spring is located between the inner top of the support sleeve and the top surface of the support rod.

[0014] Preferably, the positioning plate is fitted to the output side of the placement plate, and the swing assembly includes a rotating shaft, a connecting block, a locking component, and a handle. One end of the rotating shaft is fixedly connected to the side of the positioning plate, the connecting block is fixed on the mounting bracket, and both ends of the rotating shaft pass through the connecting block and rotate in cooperation with the connecting block. The locking component is a locking nut that is threadedly engaged with the end of the rotating shaft, and the handle is fixed to the end of the rotating shaft and located outside the locking component.

[0015] Advantages of this invention:

[0016] Employing a complex aligning structure combining "wave-like air cushion + stepped flow guide + ultrasonic radiation pressure," this method differs from traditional mechanical contact aligning methods. The wave-like air cushion, formed by a flow stabilizer and an air outlet assembly, suspends the cigarette box cardboard on the conveyor belt surface, significantly reducing direct friction between the hot-stamped surface and the conveyor surface. This fundamentally prevents quality defects such as wear and scratches on the hot-stamped layer. The stepped flow guide assembly achieves progressive guidance and correction through multiple sets of flow guide modules with gradually varying spacing. Combined with the vertical acoustic radiation pressure generated by the ultrasonic transducer, it can precisely correct the conveying posture of the cigarette box cardboard, ensuring that it is always conveyed stably along the preset trajectory, laying a solid foundation for the regularity of subsequent material collection.

[0017] Employing a gravity-adaptive drive design, this system requires no additional power source. As cigarette packs gradually accumulate on the placement plate, their gravity causes the plate to compress the elastic support component and move downwards. Through the orderly transmission of information via components such as push blocks, levers, and sliding blocks in the linkage assembly, the side-aligning block is driven to synchronously center and squeeze along the limiting sliding piece, automatically completing the side alignment of the cigarette packs. The positioning plate works in conjunction with the swing assembly, and the end limit angle can be adjusted via a handle, easily adapting to the collection needs of cigarette packs of different sizes. This automated design significantly reduces manual alignment operations, lowers human intervention costs, and avoids secondary damage that may be caused by manual operation.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1 As shown, the conveying and feeding device in the hot stamping production of cigarette boxes includes a conveying device 1 and a collecting device 2. The output end of the conveying device 1 is fixedly connected to the input end of the collecting device 2. After the hot stamping completed cigarette box paperboard is conveyed and regulated by the conveying device 1, it directly enters the collecting device 2 for automatic regulated collection, realizing continuous and automated conveying and feeding of the hot stamped cigarette box paperboard.

[0031] Conveying device 1 is used to achieve the posture regularization and stable conveying of cigarette box cardboard, and includes conveyor belt 3, limiting component 4, conveying and regularizing component 5, and supporting structure:

[0032] like Figure 2 , Figure 5 As shown, the conveyor belt 3 is mounted on a support frame, and a drive motor is fixed on the support frame. The output shaft of the drive motor is fixedly connected to the drive roller of the conveyor belt 3 to drive the conveyor belt 3 to rotate in the conveying direction.

[0033] As shown in Figures 2 and 3, the limiting component 4 is fixed on the support frame and located between the input end of the conveyor belt 3 and the conveying alignment component 5, and is used to perform preliminary position calibration on the incoming cigarette box cardboard.

[0034] The limiting component 4 includes two limiting plates arranged opposite each other, which are attached to both sides of the conveying surface of the conveyor belt 3;

[0035] On the opposite sides of the two limiting plates, there are multiple arc-shaped rubber blocks. When the cigarette box cardboard passes by, the arc-shaped rubber blocks make initial correction to the cigarette box cardboard through elastic contact, while avoiding hard contact that scratches the surface of the cigarette box cardboard.

[0036] When the cigarette box cardboard enters the conveyor surface of conveyor belt 3, if the cardboard deviates slightly, its edge will contact the curved rubber block. The elastic deformation of the rubber block can buffer the impact force, preventing the cardboard edge from being scratched or crushed. At the same time, the elastic rebound force of the rubber block will generate a reverse thrust on the deviated cardboard, pushing the cardboard back to the center of the conveyor channel, completing the initial position correction and laying the foundation for subsequent precise alignment.

[0037] The conveying and straightening component 5 is fixed on the support frame and located downstream of the limiting component 4. It is used to achieve precise straightening of the cigarette box cardboard posture. It includes a cover 9, a stepped flow guide component, a flow stabilizer 6, an air outlet component 7, a pressing component 8, and an ultrasonic transducer 11. The conveying and straightening component 5 achieves precise straightening of posture through the cooperation of the three components. The oscillating air cushion forms periodic vibrations through bidirectional oblique air holes, so that the cigarette box cardboard has no hard contact with the conveyor belt 3. This avoids wear on the hot stamping layer and gives the cardboard posture adjustment freedom. The stepped flow guide component narrows along the conveying direction and gradually guides and corrects the deviation of the vibrating cardboard. The vertical sound radiation pressure generated by the ultrasonic transducer 11 presses the vibrating cardboard stably against the surface of the air cushion, avoiding excessive bouncing. At the same time, it makes the edge of the cardboard fit more tightly with the flow guide module 10. The three components form a closed loop of vibration adjustment-guide correction-stable limiting, which effectively solves the problems of warping and insufficient straightening accuracy of thin cardboard.

[0038] like Figure 2 , Figure 6 As shown, the cover 9 is a rectangular cover structure with openings at both ends. It is fixed to the support frame and covers the conveyor surface of the conveyor belt 3, forming a relatively enclosed and regular space to avoid interference from external airflow.

[0039] like Figure 6 As shown, the stepped flow guide assembly is fixed to the inner wall of the cover 9, and multiple sets of flow guide modules 10 are arranged sequentially along the conveying direction:

[0040] Each flow guiding module 10 includes multiple vertical plates that are fixed at equal intervals to the inner side wall of the cover 9;

[0041] Along the conveying direction, the distance between two adjacent sets of guide modules 10 gradually decreases, that is, along the conveying direction, the effective conveying width inside the cover 9 gradually narrows; when the cigarette box cardboard moves with the conveyor belt 3, it is gradually adjusted to a posture parallel to the conveying direction by the step-like narrowing guide of the guide module 10.

[0042] The front guide modules 10 have a larger spacing, which can accommodate cigarette box cardboard with a certain offset, and avoid the cardboard edge from hard collision with the guide modules 10. The rear guide modules 10 have a gradually narrowing spacing, and guide the cardboard to gradually move towards the conveying center through "progressive extrusion". Combined with the vibration characteristics of the cardboard on the undulating air cushion, the attitude correction from "coarse adjustment" to "fine adjustment" is achieved.

[0043] like Figure 3 , Figure 5 As shown: The flow stabilizer 6 is fixed on the support frame and located at the lower end of the conveying surface of the conveyor belt 3. Its input end is connected to a circulating air guide pipe, and a valve is provided on the circulating air guide pipe to regulate the airflow pressure and flow rate.

[0044] The air outlet assembly 7 consists of two rows of inclined air guide holes on the conveying surface of the conveyor belt 3, as shown in the enlarged view of Figure 5. The inclination direction of the two rows of inclined air guide holes is such that one row is inclined in the conveying direction and the other row is inclined in the opposite conveying direction.

[0045] The airflow of the flow stabilizer 6 passes through the air outlet component 7 and forms a wavy air float through the relatively inclined oblique air guide hole, causing the cigarette box cardboard to vibrate slightly in the air float state, which, together with the stepped flow guide component, achieves adaptive posture adjustment.

[0046] like Figure 4 As shown, the clamping components 8 are symmetrically arranged on both sides of the cover 9 to ensure that the conveyor belt 3 and the flow stabilizer 6 are tightly fitted together to prevent airflow leakage.

[0047] The clamping assembly 8 includes a fixed frame 12, a T-shaped positioning rod 13, a roller frame, a roller 14, and a clamping compression spring;

[0048] The fixed frame 12 is fixed to the side of the support frame, and the T-shaped positioning rod 13 slides through the fixed frame 12; the roller frame is fixed to the bottom of the T-shaped positioning rod 13, and the roller 14 is rolled on the roller frame.

[0049] The compression springs are located on both sides of the T-shaped positioning rod 13, with both ends fixed between the fixing frame 12 and the roller frame, and are always in a compressed state. They continuously apply downward pressure to the roller 14, so that the conveyor belt 3 fits tightly against the top surface of the flow stabilizer 6, forming a closed airflow chamber. This prevents the airflow output by the flow stabilizer 6 from leaking from the edge of the conveyor belt 3, ensuring that the airflow is concentrated through the air outlet component 7 located at the cover 9. That is, the inclined air guide hole of the air outlet component 7 forms a stable undulating air float. On the other hand, the rolling contact of the roller 14 rotates synchronously with the conveyor belt, which does not affect the normal conveying of the conveyor belt and can continuously maintain airtightness, ensuring the stability of the air float effect.

[0050] like Figure 6 As shown, multiple rows of ultrasonic transducer groups are fixed on the top surface inside the cover 9. Each row of ultrasonic transducer groups is correspondingly arranged between two sets of flow guiding modules 10. Each row of ultrasonic transducer groups includes multiple ultrasonic transducers 11, which emit sound waves that generate vertically downward acoustic radiation pressure. The vertically downward acoustic radiation pressure generated by the sound waves can stably press the slightly vibrating cardboard onto the surface of the fluctuating air cushion, preventing the cardboard from excessively bouncing or shifting due to airflow fluctuations. At the same time, the high-frequency sound waves can make the edges of the cardboard fit more closely with the flow guiding module 10, assisting the stepped flow guiding component in completing fine posture correction. Especially for thin cigarette box cardboard, ultrasonic pressure can effectively suppress its warping and ensure regularity and accuracy.

[0051] Meanwhile, the ultrasonic transducer 11 operates at a frequency of 20-100kHz. This frequency range can generate stable vertical acoustic radiation pressure, which can stably press the cigarette box cardboard onto the surface of the undulating air cushion to avoid excessive bouncing, without damaging the cigarette box cardboard and the hot stamping layer. Its multi-row arrangement corresponding to the gaps of the flow guiding module 10 can stably limit the cardboard body without affecting the correction of the flow guiding module 10. It is especially suitable for thin cigarette box cardboard and effectively suppresses its warping and deformation.

[0052] The collecting device 2 is used to automatically unload and straighten the conveyed cigarette box cardboard, as shown in Figures 7-9. It includes a placement plate 15, a side straightening assembly 16, a positioning plate 17, an elastic support assembly 18, and a swing assembly 26.

[0053] The input side of the placement plate 15 is in close contact with the output surface of the conveyor belt 3. Its top surface is a sloping structure that slopes downward from the input side to the output side, which makes it easy for the cigarette box cardboard to slide into the collection area along the sloping surface. The bottom surface of the placement plate 15 is provided with a cooperative structure of elastic support component 18 and linkage component.

[0054] like Figure 9 As shown, the elastic support assembly 18 is fixed to the bottom surface of the placement plate 15, and includes a support sleeve, a support rod, and a support compression spring.

[0055] The support sleeve is fixed to the bottom surface of the placement plate 15 and sleeved on the outside of the support rod. The bottom end of the support rod is fixed to the ground by expansion bolts to ensure the support stability of the elastic support assembly 18.

[0056] The support compression spring is located between the top of the support sleeve and the top surface of the support rod. In the initial state, the elastic force of the support compression spring is balanced with the gravity of the placement plate 15, so that the placement plate 15 maintains the initial height. When the cigarette box cardboard is piled up on the placement plate 15, the total gravity increases, the support compression spring is compressed, and the placement plate 15 moves down accordingly.

[0057] After the stacked cigarette box cardboard is unloaded, the weight on the placement plate 15 disappears, and the elastic rebound force of the supporting compression spring will push the support sleeve upward, causing the placement plate 15 to return to its initial position, preparing for the next round of cardboard collection; at the same time, during the process of the cardboard falling to the placement plate 15, the elastic support component can absorb the impact force of the falling cardboard through slight downward cushioning, avoiding damage to the hot stamping surface or displacement of the cardboard due to impact.

[0058] Side-aligning components 16 are symmetrically arranged on both sides of the placement plate 15 to automatically align the side positions of the cigarette box cardboard, such as... Figure 8 As shown, it includes a side guide block 19, a limiting sliding member 25, and a linkage assembly:

[0059] The side guide block 19 consists of two pieces arranged opposite each other. Their opposing surfaces are flat and covered with a rubber layer, while their other side is beveled for engagement with the linkage assembly.

[0060] The limiting sliding component 25 includes a limiting sliding protrusion fixed to the side of the side guide block 19 and a limiting sliding groove fixed to the side of the placement plate 15. The limiting sliding protrusion and the limiting sliding groove slide together, restricting the side guide block 19 to move only along the width direction of the placement plate 15. The fitting gap between the limiting sliding protrusion and the limiting sliding groove is ≤0.1mm, ensuring that the side guide block 19 moves smoothly without shaking.

[0061] The linkage component is used to drive the center-side alignment block 19 to move towards the center as the placement plate 15 moves downward, such as... Figure 8 As shown:

[0062] The linkage components include a push block 20, a push rod bracket 21, a lever 22, a sliding block 23, and a slide groove 24;

[0063] One side of the push block 20 is an inclined surface, which fits against the lower end of the inclined surface of the side guide block 19. The inclination angle of the two inclined surfaces is 45 degrees, forming a 1:1 transmission ratio. The push block 20 is fixed to the top of the top rod frame 21.

[0064] The bottom end of the push rod bracket 21 is hinged to one end of the lever 22, and the middle part of the lever 22 is hinged to the mounting bracket; the other end of the lever 22 is hinged to the sliding block 23.

[0065] The sliding block 23 slides within the slide groove 24, which is fixed to the bottom surface of the placement plate 15.

[0066] When the placement plate 15 moves down, the slide 24 moves down accordingly, causing the sliding block 23 to slide along the slide, which in turn drives the lever 22 to rotate. The top rod frame 21 pushes the push block 20 upward, and the push block 20 drives the side straightening block 19 to move towards the middle along the limiting slide through the inclined surface, thereby realizing the automatic straightening of the side of the cigarette box cardboard.

[0067] The positioning plate 17 is fitted onto the output side of the placement plate 15 to limit the end position of the cigarette box cardboard; for example... Figure 7 , 9 As shown:

[0068] The swing assembly 26 includes a rotating shaft fixed to the side of the positioning plate 17 and a connecting block fixed to the mounting bracket. The two ends of the rotating shaft are rotatably connected to the mounting bracket through the connecting block.

[0069] One end of the rotating shaft passes through the connecting block and is fixedly connected to the locking part 27 with a locking nut. The locking nut is threaded with the rotating shaft and connected to the handle 28. Loosen the locking part 27, rotate the handle 28 to adjust the swing angle of the positioning plate 17, and then tighten the locking part 27 to achieve positioning and fixation, which facilitates the removal of the neatly arranged cigarette box cardboard.

[0070] Actual work process:

[0071] The hot-stamped cigarette box cardboard is fed into the conveyor belt 3 input end. First, it is corrected by the elastic limit plate of the limit component 4 to prevent the cardboard from shifting significantly into the subsequent straightening process.

[0072] When the cardboard enters the housing 9 of the conveyor straightening component 5, the flow stabilizer 6 at the lower end of the support frame is activated. The airflow is delivered to the flow stabilizer 6 through the circulating air guide pipe, and then through multiple air outlet components 7 opened on the conveyor surface of the conveyor belt 3. At the same time, because the two rows of inclined air guide holes of the air outlet component 7 are inclined in the conveying direction and the reverse conveying direction respectively, the two airflows converge on the surface of the conveyor belt to form a undulating air cushion. The bidirectional impact of the airflow causes the air cushion to exhibit periodic fluctuations, so that the cardboard and the conveyor belt 3 maintain a small suspension gap (neither detaching from the conveyor belt nor making hard contact), causing the cigarette box cardboard to vibrate slightly in a suspended state. The cardboard has no hard contact with the conveyor surface, which avoids wear on the hot stamping layer and allows the cardboard to have the freedom of posture adjustment.

[0073] Meanwhile, the stepped flow guide components inside the cover 9 are arranged in a narrowing manner along the conveying direction, and multiple sets of flow guide modules 10 form a progressive guide channel. The cigarette box cardboard under vibration is conveyed to the subsequent direction under the push of the conveying airflow. During the process, the edge of the cardboard gently contacts the vertical plate of the flow guide module 10. The stepped narrowing channel gradually corrects the offset angle of the cardboard. With the vertical sound radiation pressure generated by the ultrasonic transducer 11 on the top surface of the cover 9, the cardboard is stably pressed onto the undulating air cushion. The vibration adjustment and the guide correction work synchronously to achieve adaptive alignment of the posture.

[0074] The undulating air cushion not only performs the function of regularization, but also assists in the conveying through the directional thrust of the airflow. The airflow with the air holes tilted in the opposite direction of conveying forms a "lifting buffer layer", while the airflow with the air holes tilted in the direction of conveying provides forward driving force. Combined with the operating power of the conveyor belt 3 itself, it ensures that the cigarette box cardboard is suspended and regularized, and is always stably conveyed to the collection device 2 along the preset trajectory, and is conveyed into the collection device 2 as soon as possible.

[0075] That is, the cigarette box cardboard is conveyed to the placement plate 15 by the conveyor belt 3 and slides into the collection area along the inclined surface of the placement plate 15. As the cigarette box cardboard accumulates, the total weight of the placement plate 15 increases, the support compression spring of the elastic support component 18 is compressed, the placement plate 15 moves down, and the side straightening block 19 is driven to move towards the middle through the linkage component, so as to realize the automatic straightening of the side of the cigarette box cardboard. The positioning plate 17 restricts the end position of the cigarette box cardboard.

[0076] Specifically, as the amount of cardboard stacked increases, the overall gravity gradually presses the placement plate 15 downward, causing the elastic support component 18 on the bottom surface to compress the support compression spring. During the downward movement of the placement plate 15, the sliding groove 24 on the bottom surface simultaneously drives the sliding block 23 to slide downward. The sliding block 23 pulls one end of the lever 22 downward through the hinge. The lever 22 rotates around the central hinge seat and pushes the other end upward, thereby driving the top rod frame 21 to push the pushing block 20 upward. The inclined surface of the pushing block 20 fits against the inclined surface of the side straightening block 19, and the upward force is converted into a horizontal thrust, driving the two opposing side straightening blocks 19 to move synchronously towards the center along the limiting sliding member 25, performing side compression and straightening of the cigarette box cardboard on the placement plate. The more cardboard stacked, the greater the gravity, and the stronger the squeezing force of the side straightening blocks, achieving an adaptive match between "stack amount and straightening force".

[0077] Once the collected cigarette box cardboard reaches the preset quantity, the position of the positioning plate 17 can be adjusted by the swing component 26 to achieve manual unloading; the total weight of the placement plate 15 decreases, the support compression spring of the elastic support component 18 resets, the placement plate 15 moves upward, and the linkage component drives the side guide block 19 to reset to the initial position, waiting for the next batch of cigarette box cardboard to be transported and collected.

[0078] The positioning plate 17 of the collecting device is used to limit the end position of the cigarette box cardboard to prevent end deviation during feeding. When the cardboard accumulates to the preset amount and needs to be unloaded, the locking part 27 is loosened again, and the handle 28 is turned to lift the positioning plate 17 upward to release the end limit. The accumulated cardboard can slide out along the inclined surface of the placement plate 15 to complete the unloading operation.

[0079] To further facilitate use, a gravity sensor can be installed on the bottom surface of the placement plate 15. When the gravity sensor detects that the total weight of the stacked cigarette box cardboard reaches a preset threshold, an audible and visual alarm will prompt the operator to unload the material. The operator can loosen the locking piece 27, turn the handle 28 to lift the positioning plate 17 upward, release the end limit, and the stacked cardboard will slide out along the inclined surface of the placement plate 15 to complete the unloading.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
