Description

Technical Field

[0001] This utility model relates to the technical field of tobacco production, and in particular to a suction claw for a tobacco smoke machine with an adjustable clamping angle structure. Background Technology

[0002] Tobacco machine suction claws are key pneumatic components used in automated tobacco production lines to grip, convey, and position cigarettes or cigarette packs. They are typically made of wear-resistant, flexible materials and have internal vacuum adsorption channels. Their working principle involves generating negative pressure through an air source, creating suction on the claw surface to stably grip cigarettes or cigarette packs, achieving precise gripping and transfer in high-speed machinery. The design of the suction claws must balance adsorption force, flexibility, and durability to avoid damage to tobacco products while ensuring production efficiency and continuity. In tobacco production, suction claws are widely used in cigarette packaging, carton assembly, and conveying processes, serving as an important auxiliary tool for achieving automated production and improving efficiency.

[0003] In the tobacco processing machine manufacturing process, the suction claw, as a key component for grasping tobacco, directly affects the surface quality of the tobacco product due to its claw tip structure. Currently, existing suction claw technologies generally employ a rigid contact design, lacking an effective buffering mechanism. This results in a hard collision between the suction claw and the tobacco surface during grasping. Because tobacco material is inherently porous and has a fragile surface, this direct contact method makes it difficult to adaptively adjust the grasping force. When the mechanical grasping force exceeds the tobacco's tolerance threshold, it easily causes physical damage to the tobacco surface, such as indentations, breakage, or structural loosening. This not only reduces the product's appearance quality but may also affect the stability of subsequent processing steps, thereby restricting the yield and material utilization rate in the tobacco production process. Utility Model Content

[0004] In view of the problem that the existing suction claws for tobacco smoke machines lack buffering function at the claw tip, which easily causes physical damage to the surface of tobacco during the gripping process, affecting product quality and production stability, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a suction claw for tobacco smoke machines with an adjustable gripping angle structure. The purpose is to solve the problem that existing suction claws for tobacco smoke machines lack a buffer function at the claw tip, which easily causes physical damage to the tobacco surface during the gripping process, affecting product quality and production stability.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a suction claw for a tobacco smoke machine with an adjustable gripping angle structure, including a base plate, a claw clamping mechanism, a suction cup mechanism, and a buffer mechanism. The claw clamping mechanism includes a claw clamping body movably mounted below the base plate. The buffer mechanism includes a claw clamping block movably mounted inside the claw clamping body. A buffer groove is provided inside the claw clamping body. The claw clamping block is slidably mounted inside the buffer groove. A sliding rod is fixedly installed inside the buffer groove. A slider is slidably mounted on the surface of the sliding rod. A connecting seat is fixedly installed inside the claw clamping block. A buffer rod is movably mounted between the connecting seat and the slider.

[0007] The suction cup mechanism includes two sets of sliding racks movably mounted on both sides of the substrate surface. A suction cup base is fixedly mounted at the lower end of the sliding rack, and a suction cup body is fixedly mounted on the lower surface of the suction cup base.

[0008] As a preferred embodiment of the suction claw for a tobacco smoke machine with an adjustable clamping angle structure described in this utility model, wherein: mounting seats are fixedly installed on both sides of the upper surface of the substrate.

[0009] As a preferred embodiment of the suction claw for a tobacco smoke machine with an adjustable clamping angle structure described in this utility model, a drive motor is fixedly installed on the rear surface of the substrate, and a drive gear is driven and installed at the output end of the drive motor. A first driven gear and a second driven gear are rotatably installed on both sides of the surface of the substrate, and the first driven gear and the drive gear mesh with each other.

[0010] As a preferred embodiment of the suction claw for a tobacco smoke machine with an adjustable clamping angle structure described in this utility model, the first driven gear and the second driven gear are both meshed with the sliding rack.

[0011] As a preferred embodiment of the suction claw for a tobacco smoke machine with an adjustable clamping angle structure described in this utility model, wherein: a rotating rod is fixedly installed at the lower end of both the first driven gear and the second driven gear, a transmission rod is rotatably installed at the lower end of the rotating rod, and the claw body is fixedly installed at the lower end of the transmission rod.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This utility model, through the buffer mechanism, first squeezes and grasps the tobacco through the claw gripper when the tobacco is gripped by the claw gripper mechanism. The squeezing force of the claw gripper is buffered by the inner and outer springs, realizing adaptive adjustment of the gripping force. This effectively avoids damage to the tobacco surface due to excessive force, improves the stability and safety of the gripping process, and ensures the appearance quality and processing yield of tobacco products.

[0017] 2. This utility model, through its claw gripping mechanism, uses a drive motor to rotate the active gear when gripping tobacco. The active gear drives the first and second driven gears to rotate synchronously in opposite directions. Finally, through the rotating rod and connecting rod, the claw grippers on both sides rotate towards the center to achieve gripping. Simultaneously, the rack of the suction cup mechanism rises synchronously, and the suction cup body adsorbs and pulls the tobacco upward. Through the synergistic action of the claw gripping mechanism and the suction cup mechanism, a dual gripping method of mechanical gripping and negative pressure adsorption is achieved. This not only improves the stability and accuracy of the gripping process but also effectively prevents the tobacco from shifting or falling off during gripping, improving the overall gripping efficiency and reliability. It is suitable for high-speed automated production environments and also achieves adjustable gripping angle. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1 , Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a suction claw for a tobacco smoke hood with an adjustable clamping angle structure. This suction claw for a tobacco smoke hood with an adjustable clamping angle structure includes a base plate 1, a claw clamping mechanism 3, a suction cup mechanism 4, and a buffer mechanism 5. The claw clamping mechanism 3 includes a claw clamping body 308 movably installed below the base plate 1. The buffer mechanism 5 includes a claw clamping block 502 movably installed inside the claw clamping body 308. A buffer groove 501 is provided inside the claw clamping body 308. The claw clamping block 502 is slidably installed inside the buffer groove 501. A slide rod 506 is fixedly installed inside the buffer groove 501. A slider 507 is slidably installed on the surface of the slide rod 506. A connecting seat 511 is fixedly installed inside the claw clamping block 502. A buffer rod 508 is movably installed between the connecting seat 511 and the slider 507.

[0027] Several sets of anti-slip protrusions 503 are fixedly installed on the inner surface of the claw block 502, an inner spring 510 is installed on the inner side of the slider 507, and an outer spring 509 is installed between the outer side of the slider 507 and the inner wall of the buffer groove 501.

[0028] Limiting grooves 504 are provided on both sides of the inner wall of the buffer groove 501. A limiting rod 505 is fixedly installed inside the limiting groove 504, and the claw block 502 is slidably installed on the surface of the limiting rod 505.

[0029] During use, the claw mechanism 3 is activated first, causing the claw body 308 to rotate towards the center to complete the gripping action of the tobacco. At the same time, the sliding rack 401 of the suction cup mechanism 4 rises synchronously, driving the suction cup body 403 to adsorb the tobacco and lift it upward. During the gripping process of the claw body 308, the buffer mechanism 5 begins to function. The claw block 502 slides along the surface of the slide bar 506 in the buffer groove 501 and is connected to the slider 507 through the buffer bar 508. When the slider 507 moves on the slide bar 506, the inner spring 510 and the outer spring 509 provide elastic support and buffering for the slider 507, respectively, so that the squeezing force of the claw block 502 on the tobacco is adaptively adjusted to avoid damage caused by hard contact. The anti-slip protrusion 503 on the inner side of the claw block 502 enhances the friction and prevents the tobacco from sliding. The limiting rod 505 in the limiting groove 504 constrains the movement trajectory of the claw block 502 to ensure that it slides smoothly and does not deviate, thereby achieving efficient, stable and safe tobacco gripping operation.

[0030] Example 2

[0031] Reference Figures 1-2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the suction cup mechanism 4 includes two sets of sliding racks 401 that are movably installed on both sides of the surface of the substrate 1. The lower end of the sliding racks 401 is fixedly installed with a suction cup seat 402, and the lower surface of the suction cup seat 402 is fixedly installed with a suction cup body 403.

[0032] Mounting bases 2 are fixedly installed on both sides of the upper surface of substrate 1.

[0033] A drive motor 301 is fixedly mounted on the rear surface of the substrate 1. A drive gear 302 is driven and mounted on the output end of the drive motor 301. A first driven gear 303 and a second driven gear 304 are rotatably mounted on both sides of the surface of the substrate 1, and the first driven gear 303 and the drive gear 302 mesh with each other.

[0034] Both the first driven gear 303 and the second driven gear 304 mesh with the sliding rack 401.

[0035] The lower ends of the first driven gear 303 and the second driven gear 304 are both fixedly mounted with rotating rods 305. The lower ends of the rotating rods 305 are rotatably mounted with transmission rods 307, and the jaw clamp body 308 is fixedly mounted on the lower end of the transmission rods 307.

[0036] A connecting rod 306 is movably mounted between one side of the transmission rod 307 and the surface of the substrate 1. One end of the connecting rod 306 is rotatably mounted on one side of the transmission rod 307, and the other end of the connecting rod 306 is rotatably mounted on the surface of the substrate 1.

[0037] During use, the drive motor 301 starts and drives the drive gear 302 to rotate. The drive gear 302 meshes with the first driven gear 303, causing them to rotate synchronously. At the same time, the first driven gear 303 and the second driven gear 304 mesh with the sliding racks 401 on both sides, thereby driving the sliding racks 401 to rise synchronously along the surface of the substrate 1. The suction cup seat 402 at the lower end of the sliding rack 401 rises accordingly, and the suction cup body 403 applies negative pressure to the tobacco and lifts it upward. Meanwhile, the lower ends of the first driven gear 303 and the second driven gear 304 drive the rotating rod. Rotating at 305, the rotating rod 305 transmits power to the gripper body 308 via the transmission rod 307. During rotation, the transmission rod 307 is constrained by the connecting rod 306, causing the gripper body 308 to move towards the center at an adjustable angle, thus completing the gripping action of the tobacco. Through the dual action of mechanical gripping of the gripper mechanism 3 and negative pressure adsorption of the suction cup mechanism 4, not only is the stability and accuracy of the tobacco in the gripping process ensured, but it is also effectively prevented from shifting or falling off. The overall structure is highly efficient and reliable, suitable for high-speed automated production environments, and allows for flexible adjustment of the gripping angle.

[0038] The remaining structure is the same as that in Example 1.

[0039] Based on embodiments 1-2, the working principle of this utility model is as follows: First, the drive motor 301 starts, driving the active gear 302 to rotate. The active gear 302 meshes with the first driven gear 303, causing them to rotate synchronously. Simultaneously, the first driven gear 303 and the second driven gear 304 mesh with the sliding racks 401 on both sides, thereby driving the sliding racks 401 to rise synchronously along the surface of the substrate 1. The suction cup seat 402 at the lower end of the sliding rack 401 rises accordingly, and the suction cup body 403 applies negative pressure to adsorb the tobacco and lifts it upward. At the same time, the lower ends of the first driven gear 303 and the second driven gear 304 drive the rotating rod 305 to rotate. The rotating rod 305 transmits power to the claw body 308 through the transmission rod 307. During the rotation, the transmission rod 307 is constrained by the connecting rod 306, causing the claw body 308 to move towards the center at an adjustable angle, completing the clamping action of the tobacco. During the clamping process of the claw body 308, the buffer mechanism... When mechanism 5 begins to function, the gripper block 502 slides along the surface of the slide bar 506 within the buffer groove 501 and is connected to the slider 507 via the buffer rod 508. As the slider 507 moves on the slide bar 506, the inner spring 510 and the outer spring 509 provide elastic support and buffering for the slider 507, respectively, allowing the squeezing force of the gripper block 502 on the tobacco to be adaptively adjusted, avoiding damage caused by hard contact. The anti-slip protrusion 503 on the inner side of the gripper block 502 enhances friction and prevents the tobacco from sliding. The limiting rod 505 in the limiting groove 504 constrains the movement trajectory of the gripper block 502, ensuring that it slides smoothly and does not deviate. Through the dual action of the mechanical gripping of the gripper mechanism 3 and the negative pressure adsorption of the suction cup mechanism 4, not only is the stability and accuracy of the tobacco during the gripping process ensured, but it also effectively prevents it from deviating or falling off. The overall structure operates efficiently and reliably, is suitable for high-speed automated production environments, and allows for flexible adjustment of the gripping angle.
