Detailed Description of the Embodiments

[0025] To more clearly illustrate the technical solutions in the embodiments of the present utility model and the prior art, the specific embodiments of the present utility model will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts, and other embodiments can also be obtained. Additionally, the orientation terms only represent the relative positional relationship between components, not the absolute positional relationship.

[0026] The embodiments of the present utility model provide a strip box paper folding device. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , which mainly includes a strip box channel, an upper folding plate, a lower folding plate, and a folding assembly.

[0027] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, in the embodiments of the present application, the strip case paper folding device includes a strip case channel 1, an upper folding plate 2, a lower folding plate 3, and a folding assembly 4. The upper folding plate 2 and the lower folding plate 3 are arranged on both sides of the strip case channel 1, and a folding groove 5 is arranged on the strip case channel 1. The strip case paper is placed at the position transported to the folding groove 5. After the cigarette packs are stacked, the stacked cigarette packs are pushed through the folding groove 5 by a push rod. Under the extrusion of the stacked cigarette packs, part of the side surface of the strip case paper will be extruded into an inclined surface. The folding assembly 4 drives the upper folding plate 2 and the lower folding plate 3 to pass through the folding groove 5, and the upper folding plate 2 and the lower folding plate 3 move towards each other and approach, extruding the unfolded side surface of the strip case paper, so that the unfolded side surface of the strip case paper abuts against the stacked cigarette packs, and then the strip case paper is folded into shape, which is Figure 3 , Figure 4 as shown. Then the folding assembly 4 drives the upper folding plate 2 and the lower folding plate 3 to move away from each other in the reverse direction, so that the upper folding plate 2 and the lower folding plate 3 are far away from the folding groove 5. First, the folding assembly 4 drives the upper folding plate 2 and the lower folding plate 3 to move towards each other and approach to fold the unfolded side surface of the strip case paper, reducing the working intensity of the operator. Then, the folding assembly 4 drives the upper folding plate 2 and the lower folding plate 3 to move away from each other in the reverse direction, ensuring that the subsequent strip case paper can also be folded into shape, enabling the strip case paper folding device to be recycled and shortening the time required for folding the strip case paper in the entire production process.

[0028] It should be noted that, taking the Figure 1 observation perspective as the reference benchmark, the up and down directions described in this article are the Figure 1 up and down directions, the left and right directions are the Figure 1 left and right directions, and the front and back directions are the Figure 1 observation directions. The strip case channel 1 is composed of two parallel flat plates up and down.

[0029] Preferably, the ends of the upper folding plate 2 and the lower folding plate 3 can be set to be arc-shaped to avoid the upper folding plate 2 and the lower folding plate 3 scratching the strip case paper.

[0030] Referring to Figure 2 , in the embodiments of the present application, the folding assembly 4 includes a first folding rod 41, a second folding rod 42, and a swing rod 43. The swing rod 43 is arranged on one side of the strip case channel 1. One end of the first folding rod 41 and one end of the second folding rod 42 are respectively arranged at both ends of the swing rod 43. Through holes are arranged at one end of the first folding rod 41, one end of the second folding rod 42, and both ends of the swing rod 43. The first folding rod 41 and the swing rod 43, and the second folding rod 42 and the swing rod 43 are connected by pin shafts. The other end of the first folding rod 41 is welded to the upper folding plate 2, and the other end of the second folding rod 42 is welded to the lower folding plate 3. The swing rod 43 can rotate around the middle of the swing rod 43. Referring to Figure 1, when the swing rod 43 rotates counterclockwise, the end of the swing rod 43 connected to the first folding rod 41 descends, driving the upper folding plate 2 to descend, and the end of the swing rod 43 connected to the second folding rod 42 ascends, driving the lower folding plate 3 to ascend. Thus, the upper folding plate 2 and the lower folding plate 3 move towards each other and approach, squeezing the unfolded side of the strip box paper, so that the unfolded side of the strip box paper is folded into shape; when the swing rod 43 rotates clockwise, the end of the swing rod 43 connected to the first folding rod 41 ascends, driving the upper folding plate 2 to ascend, and the end of the swing rod 43 connected to the second folding rod 42 descends, driving the lower folding plate 3 to descend. Thus, the upper folding plate 2 and the lower folding plate 3 move away from each other in the opposite direction, causing the upper folding plate 2 and the lower folding plate 3 to move away from the folding groove 5. The first folding rod 41 and the swing rod 43, and the second folding rod 42 and the swing rod 43 are connected by pin shafts. When the swing rod 43 rotates to drive the first folding rod 41 and the second folding rod 42 to move, the first folding rod 41 and the second folding rod 42 can adjust the crossing angle between the first folding rod 41 and the swing rod 43, and the second folding rod 42 and the swing rod 43 by themselves, improving the smoothness of the movement of the first folding rod 41 and the second folding rod 42.

[0031] It should be noted that the shapes of the first folding rod 41 and the second folding rod 42 can be straight rods, curved rods or any other shapes, and can be specifically adjusted according to the installation environment of the entire folding device, which is not limited here.

[0032] In the embodiment of the present application, a fixed through hole is provided on the swing rod 43, and the folding assembly 4 further includes a fixed shaft 46. The fixed shaft 46 is inserted into the fixed through hole, so that the swing rod 43 can rotate around the fixed shaft 46 as the rotation center. A bearing can be provided between the fixed shaft 46 and the swing rod 43 to increase the smoothness of the rotation of the swing rod 43.

[0033] On the premise of ensuring that all components of the entire device do not affect each other, the swing rod 43 needs to switch back and forth between two different-direction rotations. In order to achieve the two different-direction rotations of the swing rod 43 with only one single-direction motor, refer to Figure 2 , in the embodiment of the present application, the folding assembly 4 further includes a driving wheel 44 and a transmission rod 45. The driving wheel 44 can be driven by a motor. Through holes are provided at both ends of the transmission rod 45, and through holes are also provided on the driving wheel 44. One end of the transmission rod 45 is connected to the swing rod 43 by a pin shaft, and the other end of the transmission rod 45 is connected to the driving wheel 44 by a pin shaft. When the driving wheel 44 rotates, it drives the transmission rod 45 to continuously ascend and descend. The transmission rod 45 makes a reciprocating motion of ascending and descending, driving the swing rod 43 to make a reciprocating rotation in the clockwise and counterclockwise directions. By using the rotation of the driving wheel 44 and driving the swing rod 43 to move in different directions through the transmission of the transmission rod 45, the structure of the entire folding device is simplified.

[0034] It should be noted that the driving wheel 44 can be an eccentric wheel.

[0035] As a preferred embodiment of the present utility model, the driving wheel 44 is arranged below the swing rod 43, and the driving wheel 44 is located on one side of the rotation center of the swing rod 43. That the driving wheel 44 is located on one side of the rotation center of the swing rod 43 means that Figure 1 from the perspective of, a vertical line is drawn through the rotation center of the swing rod 43, and the entire driving wheel 44 is located on the left or right side of the vertical line. One end of the transmission rod 45 is connected to the end of the swing rod 43 close to the transmission rod 45. By arranging the driving wheel 44 on one side of the rotation center of the swing rod 43, when the driving wheel 44 drives the transmission rod 45 to move, the transmission rod 45 is always on the side of the rotation center of the swing rod 43 where the driving wheel 44 is located, which limits the rotation amplitude of the swing rod 43, avoids the mutual influence of the components of the folding device, and improves the folding efficiency of the strip carton paper.

[0036] As a more preferred embodiment of the present utility model, one end of the transmission rod 45 is arranged at the end of the swing rod 43, and the other end of the transmission rod 45 is arranged at the edge of the driving wheel 44. The driving wheel 44 rotates the same angle in the same time, and the transmission rod 45 arranged at the edge will generate the maximum displacement, thereby driving the swing rod 43 to rotate at the maximum angle, expanding the displacement of the upper folding plate 2 and the lower folding plate 3. Without changing the installation positions of the strip carton channel 1, the first folding rod 41 and the second folding rod 42, the installation range of the upper folding plate 2 and the lower folding plate 3 is expanded, so that the sizes of the upper folding plate 2 and the lower folding plate 3 can be reduced, and the material consumption of the upper folding plate 2 and the lower folding plate 3 is saved.

[0037] In order to prevent the first folding rod 41 and the second folding rod 42 from deflecting or dropping due to their own gravity when the swing rod 43 rotates, the folding device further includes limit members 6 arranged on both sides of the strip carton channel 1. The limit members 6 can cooperate with the first folding rod 41 and the second folding rod 42 to limit the deflection angle of the first folding rod 41 and the second folding rod 42 in the up and down directions, and further limit the moving directions of the upper folding plate 2 and the lower folding plate 3, so that each folding surface of the strip carton paper can abut against the stacked cigarette packs, improving the folding effect of the strip carton paper.

[0038] Specifically, referring to Figure 2 , in the embodiment of the present application, the limit member 6 includes a first limit seat 61. The first limit seat 61 is arranged above the strip carton channel 1, and the first limit seat 61 can be fixedly connected to the strip carton channel 1 through a welding rod. A first limit hole is arranged on the first limit seat 61. When the first folding rod 41 is installed, the first folding rod 41 is inserted into the first limit hole. Since the first limit seat 61 has a certain thickness, the first limit seat 61 can limit the deflection angle of the first folding rod 41 in the up and down directions.

[0039] Specifically, referring to Figure 2, in the embodiment of the present application, the limiting member 6 further includes a second limiting seat 62. The second limiting seat 62 is arranged below the strip box channel 1, and the second limiting seat 62 can be fixedly connected to the strip box channel 1 through a welding rod. A second limiting hole is arranged on the second limiting seat 62. When the second folding rod 42 is installed, the second folding rod 42 is inserted into the second limiting hole. Since the second limiting seat 62 has a certain thickness, the second limiting seat 62 can limit the deflection angle of the second folding rod 42 in the up and down directions.
