[0001] The utility model relates to the technical field of tobacco packaging, in particular to a chain structure for conveying special-shaped cigarette boxes. Background Art
[0002] Irregular-shaped cigarette boxes are a type of tobacco product packaging material that differs from conventional quadrangular prisms. They offer novel styles and diverse specifications, serve as a significant branding tool, and possess considerable commercial value. However, the shape, size, and material of irregular-shaped cigarette boxes often differ significantly from those of conventional cigarette boxes. Furthermore, their highly specific form makes them difficult to securely place flat on conventional conveyor systems, such as chain conveyors. Consequently, existing conveyor systems in production lines are not suitable for conveying irregular-shaped cigarette boxes.

[0008] Furthermore, it also includes a guide seat;
[0009] The guide seats are arranged end to end on the side of the chain structure, and their length along the conveying direction is consistent with that of the chain block; a driving slideway is provided on one side of the guide seat facing the chain structure and parallel to the conveying direction, and the driving slideways of the guide seats are connected in sequence;

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0033] A precision conveyor chain for special-shaped cigarette boxes, such as Figures 1 to 4 As shown, its structural relationship is as follows: it includes chain blocks 1 that are hinged end to end to form a chain structure. In actual arrangement, each chain block 1 is preferably connected by a key pin or a shaft. The chain structure is tensioned by a chain drive roller and a chain tensioning roller. Its upper surface outputs linear translation motion under the drive of the chain drive roller. It also includes positioning structures 2 that are arranged in a one-to-one correspondence with the chain blocks 1.
[0034] The positioning structure includes a base 21, a mounting shaft 22, a clamping claw 23, a driving roller 24 and a supporting plate 25;
[0035] The bottom and top ends of the base 21 are respectively fixed to the upper surface of the corresponding chain block 1 and are fixed with a support plate 25; a pair of clamping claws 23 are symmetrically located at the front and rear ends of the support plate 25, and the middle part of the clamping claw 23 is rotatably mounted and connected to the base 21 through the mounting shaft 22 below the support plate 25. A rotating pair is formed between the base 21 and the clamping claw 23 to support the top end of the clamping claw 23 to retract and clamp inward toward the top of the support plate 25 and to extend and relax outward toward the front or rear of the support plate 25; the bottom end of the clamping claw 23 is installed and connected to the base 21 through a spring, and the elastic force of the spring tends to make the clamping claw 23 take an inward clamping posture.
[0036] During actual setting, a spring with a suitable elastic coefficient is selected according to the clamping requirements of the special-shaped cigarette box.
[0037] Preferably, it also includes a guide seat 3;
[0038] The guide seats 3 are arranged end to end on the side of the chain structure, and their length along the conveying direction is the same as that of the chain block 1; a driving slide 31 is provided on the side of the guide seat 3 facing the chain structure and parallel to the conveying direction, and the driving slides 31 of each guide seat 3 are connected in sequence;
[0039] The end of the driving roller 24 is fitted into the driving slideway 31 , and a moving pair is formed therebetween to support the driving roller 24 to move along the driving slideway 31 .
[0040] When the chain structure moves under the action of the chain drive roller, it drives the positioning structure to perform linear translational motion along the conveying direction. During this motion, the articulation between the chain blocks 1 makes it inevitable that there is relatively large vibration in the linear translational motion output by the chain structure to the positioning structure. The driving slide 31 and the driving roller 24 cooperate with each other to have a guiding effect, which helps to alleviate the vibration and improve the stability of the movement of the positioning structure 2.
[0041] Preferably, among the guide seats 3, the guide seat 3 located at the loading position of the special-shaped cigarette box serves as a lifting guide seat, and is further provided with a lifting slide 32, a lifting guide rail 33 and a lifting roller 34;
[0042] The lifting guide seat is bent into an L-shaped structure at the end of the driving slide 31 toward the side away from the chain structure. A lifting slide 32 is provided on the L-shaped structure toward the side of the chain structure. The lifting guide rail 33 is fixedly installed and slidably cooperates with the lifting slide 32 to form a lifting sliding pair that supports the lifting guide seat in vertical lifting or lowering.
[0043] It also includes a lifting mechanism 4, the output end of which acts on a lifting roller 34 fixed on the lifting guide seat, and the output drives the lifting guide seat to move up along the lifting sliding pair.
[0044] Preferably, the lifting guide seat is bent into an L-shaped structure at the front and rear ends of the driving slide 31 toward the side away from the chain structure, and the lifting slide 32 and the lifting guide rail 33 are arranged in pairs corresponding to a pair of L-shaped structures.
[0045] The lifting slide 32 and the lifting guide rail 33 are arranged in pairs to improve the symmetry of the lifting guide seat structure and enhance the stability of the lifting and lowering movement of the lifting guide seat.
[0046] Preferably, the lifting mechanism 4 includes a driving machine 41, a push rod 42 and a lifting ramp 43;
[0047] The lifting ramp 43 serves as the output end of the lifting mechanism 4 and is fixedly installed on the top of the push rod 42. Its top surface is an inclined surface with increasing or decreasing height along the conveying direction, and the lifting roller 34 is acted on by the bottom of the lifting roller 34; the driving motor 41 is fixedly installed, and its output end is axially connected to the push rod 42, and the output drives the lifting ramp 43 to move parallel to the conveying direction.
[0048] In actual configuration, the driving machine 41 is preferably an electric motor, a hydraulic rod or a pneumatic rod.
[0049] Preferably, the end of the inclined surface close to the lifting roller 34 is an upward convex arc surface.
[0050] The setting of the arc surface reduces the impact when the end of the lifting ramp 43 contacts the lifting roller 34, and slows down the vibration of the lifting guide seat when the lifting action starts.
[0051] Preferably, the end of the lifting roller 34 is a roller structure that can rotate around its own axis.
[0052] The roller structure at the end of the lifting roller 34 can roll on the top surface of the lifting ramp 43, reducing the friction between the lifting roller 34 and the lifting ramp 43, improving the smoothness of the lifting guide seat lifting action, and helping to extend the service life of the lifting roller 34 and the lifting ramp 43.
[0053] Preferably, the end portion of the driving roller 24 is a roller structure that can rotate around its own axis.
[0054] The roller structure at the end of the driving roller can roll in the driving slide 31. Compared with the sliding fit of the end of the driving roller 24 installed in the driving slide 31, the friction between the end of the driving roller 24 and the driving slide 31 is reduced, thereby reducing the wear between the two and extending the overall service life of the conveyor chain.
[0055] Preferably, the guide seats 3 are symmetrically arranged in pairs on both sides of the chain structure, and both ends of the driving roller 24 are respectively mounted in the driving slideways 31 of a pair of guide seats 3.
[0056] The symmetrical arrangement of the guide seats 3 in pairs improves the symmetry of the conveyor chain structure, optimizes the uniformity of load and stress distribution during its operation, thereby improving the smoothness of the movement of the positioning structure 2 and helping to extend the service life of the conveyor chain.
[0057] When a certain positioning structure of the above-mentioned special-shaped cigarette box precision conveying chain moves to the special-shaped cigarette box loading position, the work of loading the special-shaped cigarette box includes the following process:
[0058] In the first step, the positioning structure 2 moves along with the chain block 1 and, under the conveying action of the chain structure, moves to the loading position of the special-shaped cigarette box. At this time, the driving roller 24 of the positioning structure 2 enters the driving slide 31 of the lifting guide seat;
[0059] In the second step, the driving machine 41 drives the push rod 42 to extend or retract, driving the lifting ramp 43 on the push rod 42 to move parallel to the conveying direction, so that the end of the lifting ramp 43 close to the lifting roller 34 of the lifting guide seat moves closer to the lifting roller 34 until it contacts the lifting roller 34 and is inserted under the lifting roller 34, acting on the lifting roller 34 to lift the lifting roller 34 upward, driving the lifting guide seat to lift; during the lifting guide seat lifting process, the lifting slide 32 and the lifting guide rail 33 play a guiding role;
[0060] It should be noted that, depending on the relative positions of the lifting ramp 43 and the lifting roller 34, the driving machine 41 may drive the lifting guide seat to lift by either extending or retracting the driving push rod 42. Accordingly, its retraction or extension action is a reset action. After resetting, the lifting guide seat falls and resets under the action of gravity.
[0061] In the third step, the upward movement of the lifting guide seat overcomes the elastic force of the spring and drives the driving roller 24 upward. The pair of clamping claws 23 then rotate around the axis of the mounting shaft 22, and the upper ends are extended and relaxed. At the same time, the driving roller 24 moves horizontally along the driving slide 31 to adapt to the translation parallel to the conveying direction accompanying its lifting movement.
[0062] In the fourth step, the special-shaped cigarette box is placed on the support plate 25, and then the driving machine 41 drives the push rod 42 to retract or extend, driving the lifting ramp 43 on the push rod 42 to reset until the lifting ramp 43 is disengaged from and away from the lifting roller 34; the lifting guide table then falls and resets under the action of gravity, and the pair of clamping claws 23 rotate and reset around the axis of the mounting shaft 22 under the action of the spring elastic force, and the upper ends are retracted to clamp the cigarette box on the support plate 25.
