Description

Technical Field

[0001] This utility model belongs to the field of clamping equipment, and specifically relates to a clamping device for preventing deformation of composite paper in cigarette packaging. Background Technology

[0002] Cigarette packaging composite paper clamps are specialized tooling equipment used on tobacco packaging production lines. They are primarily used for the precise clamping and conveying of cigarette packaging composite paper. However, existing clamps lack adaptability to the stability of material morphology, easily leading to problems such as curling, localized warping, or "fluttering" edges on the composite paper. This affects the registration accuracy of the printing process and the regularity of die-cutting, and may also cause jamming and downtime during conveying due to morphological deviations, increasing the scrap rate. These problems stem from the significant differences in elastic modulus and moisture absorption shrinkage rate of the multilayered heterogeneous properties of cigarette packaging composite paper. If the clamping force cannot be evenly distributed, it can easily cause interlayer stress imbalance. The industry conventionally uses manual fine-tuning of the clamping gap, but loosening the gap can cause material movement during high-speed conveying, while tightening it can cause indentations and surface damage. Therefore, a new structure is needed to solve these technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a deformation-resistant clamp for cigarette pack composite paper, thereby solving the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a cigarette pack composite paper anti-deformation clamp, comprising: an adsorption component and a suction cup component. The lower surface of the adsorption component is equipped with four sets of suction cup components for adsorbing the cigarette pack composite paper. The adsorption component includes an adsorption box, a connecting frame, and hoses. The lower surface of the adsorption box is equipped with an X-shaped connecting frame. The outer surface of the adsorption box is equipped with four hoses for connecting the suction cup components. The lower surface of the connecting frame is fixed with suction cup components through hoses, fixing heads, and connecting heads. The suction cup component includes a suction cup body for adsorbing the cigarette pack composite paper. The lower surface of the suction cup body is equipped with a capillary disc for increasing the adsorption force.

[0005] In a preferred embodiment, a sealing head for connecting to an external vacuum device is installed on the outer surface of the adsorption box, and four flexible tubes are installed on the lower edge of the outer surface of the adsorption box, which are connected to the inside of the adsorption box. A connecting frame is installed at the center of the lower surface of the adsorption box. In use, the adsorption force is evenly distributed at multiple points by multiple sets of suction cup components, avoiding local stress concentration caused by single-point adsorption, effectively suppressing the deformation of the cigarette pack composite paper and ensuring its flatness.

[0006] In a preferred embodiment, a tapered fixing head is installed at the end of the connecting frame away from the adsorption box, the end of the flexible tube away from the adsorption box is connected to the upper end of the fixing head through it, and a connector is installed at the lower end of the fixing head. The cross-section of the connector is an inverted T-shaped structure.

[0007] In a preferred embodiment, the upper end of the connector is connected to the end of the hose away from the suction box via a fixing head, and a sealing ring is installed on the inner surface of the lower end of the connector.

[0011] In a preferred embodiment, the capillary disc has a circular ring structure, and the diameter of the central opening of the capillary disc matches the diameter of the suction port of the suction cup body. The surface of the capillary disc away from the suction cup body is filled with a thick water film to increase the adsorption force. In use, the capillary disc can further enhance the adsorption strength of the cigarette pack composite paper on the basis of the basic adsorption force of the suction cup body by means of capillary effect and liquid bridging effect of the thick water film.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 As the first embodiment of this utility model: a cigarette pack composite paper anti-deformation clamp, including: an adsorption component and a suction cup component. The lower surface of the adsorption component is equipped with four sets of suction cup components for adsorbing the cigarette pack composite paper. The adsorption component includes an adsorption box 100, a connecting frame 130 and a hose 120. The lower surface of the adsorption box 100 is equipped with an X-shaped connecting frame 130. The outer surface of the adsorption box 100 is equipped with four hoses 120 for connecting the suction cup components. The lower surface of the connecting frame 130 is fixed with the suction cup components through the hoses 120, the fixing head 140 and the connecting head 150. The suction cup component includes a suction cup body 210 for adsorbing the cigarette pack composite paper. The lower surface of the suction cup body 210 is equipped with a capillary disc 300 for increasing the adsorption force.

[0024] The outer surface of the adsorption box 100 is equipped with a sealing head 110 for connecting to an external vacuum device. Four hoses 120 are installed on the lower edge of the outer surface of the adsorption box 100. The hoses 120 are connected to the inside of the adsorption box 100. A connecting bracket 130 is installed at the center of the lower surface of the adsorption box 100.

[0025] A tapered fixing head 140 is installed at the end of the connecting frame 130 away from the adsorption box 100. The end of the hose 120 away from the adsorption box 100 is connected to the upper end of the fixing head 140. A connector 150 is installed at the lower end of the fixing head 140. The cross section of the connector 150 is an inverted T-shaped structure.

[0026] The upper end of the connector 150 is connected to the end of the hose 120 away from the suction box 100 via the fixing head 140. A sealing ring is installed on the inner surface of the lower end of the connector 150. The suction cup assembly also includes a connecting plate 200, a connecting post 220, a buffer post 230, a buffer spring 240, a movable plate 250, and a sealing threaded head 260.

[0027] A suction cup body 210 for adsorption is installed on the lower surface of the connecting plate 200, a connecting post 220 is installed on the upper surface of the connecting plate 200, a buffer post 230 is integrally formed on the upper surface of the connecting post 220, and a buffer spring 240 is fitted on the outer surface of the buffer post 230.

[0028] The upper end of the buffer column 230 is movably fitted with a movable plate 250. A sealing thread head 260 is installed at the center of the upper surface of the movable plate 250. The connecting plate 200, the connecting column 220, the buffer column 230, the buffer spring 240, the movable plate 250, the sealing thread head 260, and the suction cup body 210 are internally connected.

[0029] The end of the sealing thread head 260 away from the movable plate 250 is connected to the lower end of the connector 150 with a sealing thread. There are four sets of suction cup assemblies. The four sets of suction cup assemblies have the same structure. The surface of the suction cup body 210 away from the connecting plate 200 is glued with a capillary disc 300.

[0030] In use, the user first connects the sealing head 110 to an external vacuum device via a flexible tube 120, which has the same structure as the outer surface of the adsorption box 100. The vacuum device provides vacuum adsorption and release forces through the sealing head 110 and the flexible tube 120 (the vacuum device is existing technology, and its specific working principle and structure are not detailed here). In actual use, the user can connect the device to an external robotic arm to control its actions. After the above operations are completed, the user aligns the suction cup bodies 210 of the four suction cup components on the lower surface of the adsorption assembly with the cigarette pack composite paper to be clamped, positioning the adsorption assembly and suction cup components above the cigarette pack composite paper. Then, using the aforementioned mechanical device, the adsorption assembly and suction cup components are gradually brought closer to the surface of the cigarette pack composite paper. When the suction cup body 210 of the suction cup assembly contacts the surface of the cigarette pack composite paper, the buffer spring 240 on the outer surface of the internal buffer column 230 of the suction cup assembly is pressed down by the movable plate 250, thereby reducing the contact between the suction cup body 210 and the cigarette pack composite paper. The instantaneous contact force between the paper and the cigarette pack composite paper is reduced by the soft rubber structure of the suction cup body 210, and the buffer column 230 and buffer spring 240 can further reduce the instantaneous contact force, thereby preventing deformation of the contacted cigarette pack composite paper. After the suction cup bodies 210 of the multiple suction cup assemblies come into contact with the cigarette pack composite paper through the above steps, the user can then activate the external vacuum equipment to generate negative pressure suction on the suction cup bodies 210 of the suction cup assembly, thereby performing an adsorption and clamping operation on the cigarette pack composite paper. During the adsorption and clamping period... Users can perform subsequent operations on the cigarette pack composite paper. When clamping is no longer needed, users can reverse the operation of the vacuum equipment to release the cigarette pack composite paper by losing suction. During use, the suction force is evenly distributed across multiple points using multiple sets of suction cup components, avoiding local stress concentration caused by single-point suction. This effectively suppresses the deformation of the cigarette pack composite paper, ensuring its flatness. Furthermore, the synergistic suction of multiple sets of suction cups enhances clamping stability. Especially in dynamic conveying and flipping processes, it can reduce the risk of detachment caused by single-point suction failure, ensuring production continuity.

[0031] Please see Figures 1 to 4 As a second embodiment of the present invention: based on the description in the above embodiments, the capillary disc 300 is further described as having a circular ring structure, the diameter of the central opening of the capillary disc 300 is matched with the diameter of the suction port of the suction cup body 210, and the surface of the capillary disc 300 away from the suction cup body 210 is filled with a thick water film 310 for increasing the adsorption force.

[0032] When in use, during the adsorption and clamping of the cigarette pack composite paper using the suction cup body 210 operation steps of the first embodiment, when the lower surface of the suction cup body 210 contacts the surface of the cigarette pack composite paper, the capillary disk 300 on the lower surface of the suction cup body 210 and the side surface with the thick water film 310 will contact the surface of the cigarette pack composite paper. At this time, the capillary disk 300 can further enhance the adsorption strength of the cigarette pack composite paper on the basis of the basic adsorption strength of the suction cup body 210, especially for the smooth surface layer of the composite paper, which can effectively avoid slippage caused by insufficient single-point adsorption force and significantly improve the clamping stability in dynamic conveying, flipping and other processes.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
