Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a flexible straightening device for transporting cigarette boxes. Background Technology

[0002] Cigarette boxes are typically made of double-layered paper on the inside and outside, with a corrugated structure filling the middle, giving the cigarette box a certain degree of rigidity. In the process of straightening and folding the cigarette box, existing technologies usually use rigid machinery. The cigarette box is transferred through a transmission mechanism 2, and after being transmitted to a certain position, a rigid mechanical structure is used to push the cigarette box inward. After bending to a certain extent, a rigid extrusion structure is used to compress the cigarette box, thereby folding the cigarette box and bonding the adhesive joints. However, in actual use, it has been found that the rigid pushing structure may cause scratches on the surface of the cigarette box, and the rigid extrusion structure is difficult to control. In practical applications, the cigarette box is often damaged by the rigid extrusion structure, such as the corrugated structure collapsing, the surface of the cigarette box being damaged, and severe surface indentations. This leads to the scrapping of cigarette box products, thereby increasing production costs and prolonging the overall production time.

[0003] In actual use, it was found that when gluing the tobacco boxes at the adhesive joints, the order of folding at the two bends on both sides was often disordered. This caused the adhesive joint of the tobacco box to be unable to be effectively glued to the outside of the other bend, thus requiring manual identification and gluing afterward. This not only affected production efficiency but also increased the workload and labor intensity of the workers. Summary of the Invention

[0004] The purpose of this utility model is to provide a flexible straightening device for transporting cigarette boxes, so as to solve the technical problems mentioned in the background art, such as the rigid straightening device easily causing damage to the cigarette box and the easy disorder of the adhesive sequence at the bending point of the cigarette box.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible alignment device for transporting cigarette boxes, comprising a workbench, a transmission mechanism on the workbench, fixed plates on both sides of the transmission mechanism, two reversing wheels on each fixed plate, a first reversing mechanism, a second reversing mechanism, a third reversing mechanism, and a detour mechanism on each fixed plate, a flexible belt arranged along the corresponding reversing wheel, the first reversing mechanism, the second reversing mechanism, the third reversing mechanism, and the detour mechanism on each fixed plate, and multiple movable hinge rods on each fixed plate, with a flexible tube connected to the multiple hinge rods on the same fixed plate.

[0006] Preferably, the first reversing mechanism includes a concave plate fixedly mounted on a fixed plate, and the flexible belt is inserted into the concave plate.

[0007] Preferably, the second reversing mechanism includes a plurality of inclined wheels arranged along the extension direction of the fixed plate, a tapered pusher is provided on the fixed plate, the flexible belt is staggered on the plurality of inclined wheels and in contact with the pusher, and a plurality of buffer posts are fixed on the side of the fixed plate away from the pusher, the height of the plurality of buffer posts gradually decreases along the direction away from the pusher.

[0008] Preferably, the third reversing mechanism includes a pressure roller rotatably mounted on a corresponding fixed plate, and the flexible belt is disposed at the bottom of the pressure roller and wound around the corresponding reversing roller.

[0009] Preferably, the detour mechanism includes a first rotating wheel rotatably disposed on the side of the fixed plate away from the transmission mechanism, and a plurality of second rotating wheels are disposed on the side of each fixed plate away from the transmission mechanism. The flexible belt is staggered and distributed on the corresponding second rotating wheels and then wound around the reversing wheel on the other side.

[0010] Preferably, the outer side of the fixing plate is provided with a plurality of fixing rods corresponding to the hinge rod, each fixing rod is provided with a connector, and each connector is provided with a movable rod that can move, the movable rod being hinged to the hinge rod.

[0011] Preferably, the flexible belt reversing stage between the first reversing mechanism and the second reversing mechanism is the first reversing segment, and the reversing stage between the second reversing mechanism and the third reversing mechanism is the second reversing segment.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the synergistic effect of flexible belts and flexible tubes, the cardboard can be naturally bent and shaped during the transmission process of the cigarette box, replacing the traditional stamping folding method. This slowly guides the cigarette box from a horizontal state to a bent state, and then to a folded state. No rigid mechanical compression is used during this process, avoiding the collapse of the corrugated structure and preventing indentations and damage to the surface, thus saving production costs. By subdividing the second reversing section (H section) into H1 and H2, the folding of the cigarette box at the bending point is performed sequentially before the folding is completed in the second reversing section. This ensures the correct placement of the adhesive, reduces the need for re-screening, improves processing efficiency, and reduces the workload of workers. Attached Figure Description

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Cigarette boxes are typically made of double-layered paper on the inside and outside, with a corrugated structure filling the middle, giving the cigarette box a certain degree of rigidity. In the process of straightening and folding the cigarette box, existing technologies usually use rigid machinery. The cigarette box is transferred through a transmission mechanism 2, and after being transmitted to a certain position, a rigid mechanical structure is used to push the cigarette box inward. After bending to a certain extent, a rigid extrusion structure is used to compress the cigarette box, thereby folding the cigarette box and bonding the adhesive joints. However, in actual use, it has been found that the rigid pushing structure may cause scratches on the surface of the cigarette box, and the rigid extrusion structure is difficult to control. In practical applications, the cigarette box is often damaged by the rigid extrusion structure, such as the corrugated structure collapsing, the surface of the cigarette box being damaged, and severe surface indentations. This leads to the scrapping of cigarette box products, thereby increasing production costs and prolonging the overall production time.

[0025] To resolve the above technical issues, please refer to Figures 1 to 7 As shown, an embodiment of the present invention provides a flexible alignment device for transporting cigarette boxes, comprising a workbench 1, a transmission mechanism 2 on the workbench 1, and fixed plates 3 on both sides of the transmission mechanism 2. Each fixed plate 3 is provided with two reversing wheels 301, and each fixed plate 3 is provided with a first reversing mechanism 31, a second reversing mechanism 32, a third reversing mechanism 33, and a detour mechanism 34. Each fixed plate 3 is provided with a flexible belt 302 arranged along the corresponding reversing wheel 301, the first reversing mechanism 31, the second reversing mechanism 32, the third reversing mechanism 33, and the detour mechanism 34. Each fixed plate 3 is provided with... The system includes multiple movable hinge rods 4, all connected to a flexible tube 401 on the same fixed plate 3. The first reversing mechanism 31 includes a concave plate 3101 fixedly mounted on the fixed plate 3, with a flexible belt 302 inserted into the concave plate 3101. The second reversing mechanism 32 includes multiple inclined wheels 3201 extending along the direction of the fixed plate 3. A tapered pusher wheel 3202 is mounted on the fixed plate 3. The flexible belt 302 is staggered on the inclined wheels 3201 and contacts the pusher wheel 3202. Multiple buffer posts 3203 are fixedly mounted on the side of the fixed plate 3 away from the pusher wheel 3202. Multiple buffer posts 3203 gradually decrease in height along the direction away from the pusher wheel 3202. The third reversing mechanism 33 includes a pressure roller 3301 rotatably mounted on a corresponding fixed plate 3. The flexible belt 302 is arranged at the bottom of the pressure roller 3301 and wrapped around the corresponding reversing wheel 301. The detour mechanism 34 includes a first rotating wheel 3401 rotatably mounted on the side of the fixed plate 3 away from the transmission mechanism 2. Each fixed plate 3 has multiple second rotating wheels 3402 on the side away from the transmission mechanism 2. The flexible belt 302 is staggered on the corresponding second rotating wheels 3402 and then wrapped around the reversing wheel 301 on the other side. The fixed plate 3. Multiple fixed rods 402 corresponding to the hinge rod 4 are provided on the outer side. Each fixed rod 402 is provided with a connector 403. Each connector 403 is provided with a movable rod 404. The movable rod 404 is hinged to the hinge rod 4. The workbench 1 is provided with an upper pressing mechanism, which can prevent the cigarette box from flipping and shifting during transmission, thereby ensuring the stability of transmission. It is not shown in the figure. It can also play a certain guiding role during the gradual folding of the cigarette box, preventing the carton from swinging to the folding state in advance due to inertia, which would lead to folding failure. This technology is existing technology and will not be described in detail here.

[0026] In practical use, the transmission mechanism 2 is divided into a feeding end near the first reversing mechanism 31 and a discharging end near the third reversing mechanism 33. The reversing wheels 301 on the same fixed plate 3 are located at the feeding end and the discharging end of the transmission mechanism 2, respectively. The transmission mechanism 2 adopts existing technology and will not be described in detail here. When the equipment is started, the transmission mechanism 2 drives the smoke box to move from the feeding end to the discharging end. The flexible belt 302 moves cyclically under the action of the reversing wheel 301, the concave plate 3101, the tilting wheel 3201, the push wheel 3202, the pressure wheel 3301, and the first rotating wheel 3401 and the second rotating wheel 3402. The tilting arrangement of the tilting wheel 3201 and the push wheel 3202 can squeeze a part of the flexible belt 302, thereby achieving the effect of slowly changing the direction of the flexible belt 302. (See the attached drawings in the specification.) Figure 2 , Figure 4 and Figure 5 The L segment is the first reversing segment, which is the reversing stage between the first reversing mechanism 31 and the second reversing mechanism 32. During this process, under the action of the concave plate 3101, the bottom of the flexible belt 302 flips inward and the top flips outward.

[0027] When the cigarette box reaches the second reversing mechanism 32, the tilting wheel 3201 and the push wheel 3202 will cause the bent part of the cigarette box to bend further inward. Under the action of multiple reversing mechanisms, the middle part of the flexible belt 302 exceeds the inner side of the corresponding fixed plate 3, which can form a stable flexible extrusion on the cigarette box until the processing bends on both sides of the cigarette box reach the vertical state. Therefore, the cigarette box will gradually change from a flat state to an inward folded state during this process.

[0028] The attached diagram of the instruction manual Figure 2 , Figure 4 and Figure 5 The H segment in the middle is the reversing process from the second reversing mechanism 32 to the third reversing mechanism 33. During this process, the flexible belt 302 gradually changes from the vertical position of the first reversing segment to the state where the inward side becomes downward and the outward side becomes upward under the action of the tilting wheel 3201 and the pressure wheel 3301. This causes the part of the cigarette box that is bent to the vertical position to gradually move inward under the action of the flexible belt 302, thereby completing the folding and straightening of the cigarette box and making the adhesive part of the cigarette box complete the bonding.

[0029] In the above process, the flexible tube 401 can provide a certain degree of flexible blocking effect on the excessively high bending of the cigarette box, preventing large-scale disturbance at the higher position after the cigarette box is bent, which would cause the position of the cigarette box to deviate, resulting in ineffective adhesion at the adhesive joint of the cigarette box and creases or damage after the cigarette box is displaced. The height of the hinge rod 4 can be adjusted by changing the height of the moving rod 404. The moving rod 404 can be set on the connector 403 by bolts or other means. The hinge rod 4 can be set on the moving rod 404 by bolts. By loosening the bolts, the restriction of the hinge rod 4 and the moving rod 404 can be released, and then the corresponding adjustment can be made.

[0030] At the same time, the flexible belt 302 is used to fold and glue the cigarette box by switching back and forth between different sides, thereby avoiding the occurrence of indentations or even damage on the outer surface of the cigarette box when the rigid machinery squeezes the cigarette box, which would lead to product scrapping and thus achieve a better correction effect.

[0031] Through the synergistic effect of the flexible belt 302 and the flexible tube 401, the cardboard can be naturally bent and shaped during the transmission process of the cigarette box through the transmission mechanism 2, replacing the traditional stamping folding method. This slowly guides the cigarette box from a horizontal state to a bent state, and then to a folded state. During this process, no rigid machinery is used for squeezing, which avoids the collapse of the corrugated structure of the cigarette box and prevents indentations and damage to the surface of the cigarette box, thereby saving production costs.

[0032] Example 2

[0033] While the above embodiments can solve the problem of preventing damage to the cigarette box when the rigid machinery is straightening it, in actual use it has been found that when the adhesive is applied to the cigarette box, the order of folding at the two bends is often disordered. This results in the adhesive not being able to be effectively applied to the outside of the other bend, thus requiring manual identification and subsequent application. This affects production efficiency and increases the workload and intensity of labor for workers.

[0034] Based on the above embodiments, in order to solve the above technical problems, please refer to... Figures 1 to 7 As shown, the technical solution includes a first reversing segment and a second reversing segment. The reversing stage of the flexible belt 302 between the first reversing mechanism 31 and the second reversing mechanism 32 is the first reversing segment, and the reversing stage between the second reversing mechanism 32 and the third reversing mechanism 33 is the second reversing segment. The H segment is subdivided into H1 segment and H2 segment, meaning that the positions of the H segments on the two fixed plates 3 are different, as shown in the attached drawings. Figure 2 The fixed plate 3 on the left corresponds to segment H2, which is the area where folding is relatively slow at the bend, and the fixed plate 3 on the right corresponds to segment H1, which is the area where folding is relatively fast at the bend.

[0035] Based on the above embodiments, during use, when the smoke box enters section H, i.e., the second reversing section, the corresponding diagram in the instruction manual should be followed. Figure 2 As shown, the right side of the cigarette box is quickly folded, exposing the adhesive. Then, under the action of the transmission mechanism 2, the cigarette box continues to move and completes the H2 segment. At this time, the fold on the left side covers the fold on the right side, thus ensuring stable adhesion at the adhesive and avoiding the occurrence of disordered folding sequence at the bend.

[0036] Furthermore, the pressure roller 3301 can be movably mounted on the fixed plate 3. When it is necessary to process cigarette boxes with different adhesive positions, the positions and functions of H1 and H2 can be interchanged, thereby enabling this device to be used for processing cigarette boxes with different adhesive positions. This is not shown in detail in the figure.

[0037] By subdividing the second reversing section, H section, into H1 and H2 sections, the folding of the cigarette box at the bend is carried out in sequence before the cigarette box is folded in the second reversing section. This ensures that the cigarette box is glued in the correct position, reduces the need for further screening, thereby improving processing efficiency and reducing the workload of workers.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
