Description

Technical Field

[0001] This application relates to the field of tobacco equipment, specifically a folding device. Background Technology

[0002] On automated production lines for cigarette packaging, folding the lower long side of the outer packaging film is a crucial step. Currently, this step is generally accomplished using a folding machine. Traditional folding machines typically consist of a fixed block and a folding plate rigidly connected by welding or bolts. While this structure is simple, it has significant limitations in practical applications.

[0003] Because the plate's position is fixed, the existing folding mechanism cannot accurately and effectively complete the folding action when packaging cigarette cartons of different sizes. Either the plate is too high, resulting in incomplete folding, or it is too low, interfering with the cigarette carton's transport or causing packaging wrinkles. To adapt to changes in production specifications, operators often need to stop the machine and replace the entire folding module, or perform complex mechanical adjustments. This process not only reduces production efficiency and increases the labor intensity of workers, but also increases equipment maintenance costs and downtime. Utility Model Content

[0004] This application provides a folder to solve the above-mentioned problems.

[0005] In one embodiment, a folding device is provided, including a first connecting block, a positioning block, and a second connecting block; the first connecting block has a first mounting hole; the positioning block has a second mounting hole; a first fixing pin passes through the first mounting hole; a second fixing pin passes through the second mounting hole; the first connecting block is detachably connected to the positioning block via the first fixing pin, and the positioning block is detachably connected to the second connecting block via the second fixing pin; Both the first mounting hole and the second mounting hole have strip-shaped cross-sections; the first fixing pin is movably connected to the first mounting hole; the second fixing pin is movably connected to the second mounting hole; the extension direction of the cross-section of the first mounting hole is perpendicular to the extension direction of the cross-section of the second mounting hole.

[0006] In one embodiment, a folding block is also included, which is fixedly connected to the first connecting block.

[0007] In one embodiment, the positioning block includes a first limiting key fixed to the positioning block; the first connecting block has a first mounting groove for the first limiting key to be movably inserted.

[0008] In one embodiment, the positioning block includes a second limiting key, which is fixed on the positioning block; the second connecting block has a second mounting groove for the second limiting key to be movably inserted.

[0009] In one design, the extension directions of the first limiting key and the second limiting key are perpendicular to each other.

[0010] In one embodiment, a telescopic cylinder is also included, the output end of which is fixedly connected to the second connecting block.

[0011] In one embodiment, the number of output ends of the telescopic cylinder is two that are spaced apart from each other.

[0012] In one embodiment, the number of the first mounting hole and the number of the second mounting hole are two in a one-to-one correspondence, and the first mounting hole and the second mounting hole are spaced apart from each other.

[0013] In one embodiment, both the first fixing pin and the second fixing pin are bolts; the positioning block has a first connecting hole for threaded connection of the first fixing pin; and the second connecting block has a second connecting hole for threaded connection of the second fixing pin.

[0014] The beneficial effects of this application are: By detachably connecting the first connecting block, the positioning block, and the second connecting block, and cleverly designing the cross-sections of the first and second mounting holes as strips with mutually perpendicular extension directions, the positioning block can be adjusted in one direction relative to the first connecting block, and the second connecting block can be adjusted in another perpendicular direction relative to the positioning block. This two-dimensional adjustment capability allows the position of the folding block to be flexibly and precisely adjusted in two perpendicular directions, thus accurately adapting to the folding requirements of cigarette packs of different sizes and greatly improving the versatility of the equipment.

[0015] When product specifications need to be changed, operators only need to loosen the first and second fixing pins to easily move the positioning block and the second connecting block to the desired position, and then retighten the fixing pins to complete the adjustment. The entire process does not require replacing the entire component or using complex tools, making the adjustment fast, significantly reducing equipment downtime for debugging, and effectively improving the overall efficiency and flexibility of the production line.

[0016] This solution achieves multi-functional adjustment without introducing complex transmission mechanisms or expensive sensors; its core structure consists of only a few blocks, pins, and slotted holes. This results in low manufacturing costs, a robust and reliable structure, and convenient maintenance, making it both economically viable and worthy of widespread adoption.

[0025] This application proposes improvements and innovations, and presents the following embodiments.

[0026] In one embodiment, such as Figures 1 to 3As shown, a folding device is provided, including a first connecting block 1, a positioning block 2, and a second connecting block 3; the first connecting block 1 has a first mounting hole 11; the positioning block 2 has a second mounting hole 21; a first fixing pin 12 passes through the first mounting hole 11; a second fixing pin 22 passes through the second mounting hole 21; the first connecting block 1 is detachably connected to the positioning block 2 via the first fixing pin 12, and the positioning block 2 is detachably connected to the second connecting block 3 via the second fixing pin 22; The cross-sections of the first mounting hole 11 and the second mounting hole 21 are both strip-shaped; the first fixing pin 12 is movably connected to the first mounting hole 11; the second fixing pin 22 is movably connected to the second mounting hole 21; the extension direction of the cross-section of the first mounting hole 11 is perpendicular to the extension direction of the cross-section of the second mounting hole 21.

[0027] By detachably connecting the first connecting block 1, the positioning block 2, and the second connecting block 3, and by cleverly designing the cross-sections of the first mounting hole 11 and the second mounting hole 21 as strips with mutually perpendicular extension directions, the positioning block 2 can be adjusted in one direction relative to the first connecting block 1, and the second connecting block 3 can be adjusted in another perpendicular direction relative to the positioning block 2. This two-dimensional adjustment capability allows the position of the folding block 13 to be flexibly and precisely adjusted in two perpendicular directions, thereby accurately adapting to the folding requirements of cigarette packs of different sizes and greatly improving the versatility of the equipment.

[0028] When product specifications need to be changed, operators only need to loosen the first fixing pin 12 and the second fixing pin 22 to easily move the positioning block 2 and the second connecting block 3 to the desired position, and then retighten the fixing pins to complete the adjustment. The entire process does not require replacing the entire component or using complex tools, the adjustment speed is fast, significantly reducing equipment downtime for debugging, and effectively improving the overall efficiency and flexibility of the production line.

[0029] This solution achieves multi-functional adjustment without introducing complex transmission mechanisms or expensive sensors; its core structure consists of only a few blocks, pins, and slotted holes. This results in low manufacturing costs, a robust and reliable structure, and convenient maintenance, making it both economically viable and worthy of widespread adoption.

[0030] In one embodiment, a folding block 13 is further included, which is fixedly connected to the first connecting block 1.

[0031] Specifically, the folding block 13 is fixed to the first connecting block 1 by bolts.

[0032] In one embodiment, the positioning block 2 includes a first limiting key 23, which is fixed on the positioning block 2; the first connecting block 1 has a first mounting groove 14 for the first limiting key 23 to be movably inserted.

[0033] The introduction of the first limiting key 23 provides a precise linear guide and hard limit for the relative movement between the positioning block 2 and the first connecting block 1. It can effectively prevent the component from undergoing unexpected torsion or displacement around the fixing pin when under force.

[0034] In one embodiment, the positioning block 2 includes a second limiting key 24, which is fixed on the positioning block 2; the second connecting block 3 has a second mounting groove 33 for the second limiting key 24 to be movably inserted.

[0035] Similarly, the introduction of the second limiting key 24 provides linear guidance and hard limiting in another direction for the relative movement between the positioning block 2 and the second connecting block 3. It works in conjunction with the first limiting key 23 to construct a stable bidirectional limiting system.

[0036] In one embodiment, the extension direction of the first limiting key 23 is perpendicular to the extension direction of the second limiting key 24.

[0037] In this embodiment, the extension directions of the first limiting key 23 and the second limiting key 24 are set to be perpendicular to each other, forming a precise two-dimensional constraint system. This design can completely restrict any unnecessary rotational degrees of freedom of the positioning block 2 in the plane, retaining only the required sliding degrees of freedom, greatly enhancing the rigidity and stability of the entire folding device during movement, avoiding shaking and abnormal noise, and ensuring reliable performance under high loads.

[0038] In one embodiment, a telescopic cylinder 31 is also included, the output end of which is fixedly connected to the second connecting block 3.

[0039] By fixing the second connecting block 3 to the output end of the telescopic cylinder 31 (such as a hydraulic cylinder or an electric push rod), this embodiment achieves power drive and automated control of the folding process. Users can precisely and effortlessly fold and unfold the equipment by controlling the extension and retraction of the telescopic cylinder without manual operation, greatly enhancing the product's convenience and technological appeal, making it suitable for high-end electric adjustment equipment.

[0040] In one embodiment, the number of output ends of the telescopic cylinder 31 is two that are spaced apart from each other.

[0041] Two telescopic cylinders 31, spaced apart from each other, are connected at their output ends to the second connecting block 3, forming a symmetrical torque drive system. This design can transmit torque in a balanced manner, completely eliminate the risk of jamming of the second connecting block 3 during movement, ensure extremely smooth driving action, and significantly improve the load-bearing capacity and service life of the transmission components.

[0042] In one embodiment, the number of first mounting holes 11 and second mounting holes 21 are two in a one-to-one correspondence, and the first mounting holes 11 and second mounting holes 21 are spaced apart from each other.

[0043] By providing two mutually spaced first mounting holes 11 and second mounting holes 21, this embodiment upgrades the single-point hinge to a two-point stable support. This symmetrical layout significantly improves the stress-bearing structure, preventing the connecting blocks from deflecting and warping under stress, thereby greatly enhancing the structural rigidity and load-bearing capacity of the entire folding device, enabling it to meet more demanding load-bearing requirements.

[0044] In one embodiment, both the first fixing pin 12 and the second fixing pin 22 are bolts; the positioning block 2 has a first connecting hole 25 for threaded connection of the first fixing pin 12; the second connecting block 3 has a second connecting hole 32 for threaded connection of the second fixing pin 22.

[0045] This embodiment specifies that the fixing pin is a bolt, which is connected through a threaded hole. This not only enables the rapid and reliable assembly and disassembly of the components and facilitates maintenance, but more importantly, by tightening the bolt, the clamping force and preload of each connection part can be precisely adjusted, effectively eliminating the gaps between the components and making the structure of the folder more stable and free from shaking when it is unfolded.

[0046] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
