[0042] The utility model will be further explained in detail below by combining with the drawings and embodiments. It can be understood that the specific embodiments described here are only used for explaining the utility model, and not for limiting the utility model. In addition, it should be pointed out that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.
[0043] In the description of the utility model, unless there is explicit definition and limitation, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixed connection, can also be detachable connection, or integral; it can be mechanical connection, also can be electrical connection; it can be directly connected, also can be indirectly connected through intermediate medium, can be the communication of two elements or the interaction of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0045] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0046] like Figure 1 and Figure 2 The diagram shows a simplified schematic of a carton packaging machine in the prior art. Before entering the channel 10, only the side panels 220 on the left and right sides and the front panel 210 on the front side of the carton 200 are flat, while the other sides are folded in place. The push rod 310 pushes 5*2 cigarette packs into the semi-finished carton 200. Due to inertia, the cigarette packs are prone to shifting in the incompletely formed carton 200 under the pushing force of the push rod 310. Since the side panels 220 and the front panel 210 of the carton 200 are mechanically folded (the front panel 210 is folded by the closing piece 320 in the figure), if the cigarette packs shift in position and are folded again, the cigarette packs will overlap with the creases, causing subsequent folds to not follow the original creases, resulting in poor forming of the carton 200.
[0047] To address the aforementioned issues, this embodiment provides a carton forming channel that prevents the cigarette pack from shifting within the channel 10, thereby improving the yield rate of the subsequent carton 200 forming process. Figures 3-5As shown, the strip box forming channel comprises a left side plate 21, an upper cover plate 22, a right side plate 23 and a bottom plate 24 forming a rectangular channel 10, the upper cover plate 22 is opposite to the bottom plate 24, the left side plate 21 and the right side plate 23 are opposite, the channel 10 extends along a first direction (X direction in the figure), it can be understood that the cross-sectional shape of the channel 10 should be matched with the front side shape of the strip box 200 to make the strip box 200 move along the X direction when moving in the channel 10; the strip box forming channel further comprises a plurality of first clamping assemblies 30 arranged at the entrance of the channel 10, the plurality of first clamping assemblies 30 are arranged on the upper cover plate 22 along a second direction (Y direction in the figure, the Y direction is perpendicular to the X direction), the first clamping assembly 30 comprises a rotating piece 31 and an elastic piece 32, the rotating piece 31 is pivotally connected to the upper cover plate 22 at the middle part, in the free state, one end of the rotating piece 31 protrudes from the upper cover plate 22 and is partially located in the channel 10, one end of the elastic piece 32 is connected to the upper cover plate 22, and the other end is connected to the other end of the rotating piece 31.
[0048] The above strip box forming channel, when the push rod 310 pushes the plurality of cigarette packets and the semi-finished cigarette box into the channel 10, clamps the strip box 200 and the cigarette packet by the first clamping assembly 30, specifically, the front end of the rotating piece 31 is lifted upward under the extrusion of the strip box 200, the elastic piece 32 is compressed, the strip box 200 is clamped and stopped at this position, and then the cigarette packet will not move in the front and back directions, the closing piece 320 moves at this position to fold the front plate 210 of the strip box 200, since the position of the cigarette packet is fixed, the folding position of the front plate 210 will not interfere with the cigarette packet, thereby ensuring that the strip box 200 is folded according to the predetermined crease when forming, thereby improving the qualified rate of the strip box 200 forming.
[0049] Optionally, as shown in Figure 3 , Figure 4 and Figure 7 , the upper cover plate 22 comprises a cover plate body 221 and a pivot shaft 224, the cover plate body 221 is opposite to the bottom plate 24, an avoiding hole 2211 is formed in the cover plate body 221, and one end of the rotating piece 31 can protrude from the cover plate body 221; the pivot shaft 224 extends along the second direction and is located on the side of the cover plate body 221 away from the channel 10, the two ends of the pivot shaft 224 are connected to the cover plate body 221 respectively, the middle part of the rotating piece 31 is pivotally connected to the pivot shaft 224, and the other end of the elastic piece 32 is connected to the cover plate body 221 (the cover plate body 221 is not shown in the Figure 7 ), through the above arrangement, the avoiding hole 2211 allows one end of the rotating piece 31 to protrude from the cover plate body 221 and be partially located in the channel 10, so that the rotating piece 31 can be lifted when the strip box 200 enters the channel 10.
[0050] Optionally, as shown in Figure 7As shown, a screw 33 is threadedly connected to one end of the rotating member 31 and the elastic member 32. The screw 33's tightening height relative to the rotating member 31 is adjustable. The elastic member 32 is connected to the screw 33. By adjusting the height of the screw 33, the lifting height of the elastic member 32 in its free state remains constant, thus affecting... Figure 7 In this way, the more the screw 33 is turned downwards, the higher the right end of the rotating member 31 is lifted when the elastic member 32 is in a free state, and the more the left end of the rotating member 31 sinks. When the carton 200 lifts the left end of the rotating member 31, the more the elastic member 32 is compressed, and the greater the reaction force applied by the elastic member 32, that is, the clamping force on the carton 200 and the cigarette pack, the greater the clamping force on the carton 200. In this way, the clamping force of the first clamping assembly 30 on the carton 200 can be adjusted.
[0051] Optionally, such as Figure 6 and Figure 7 As shown, the rotating component 31 includes a rotating part 311, the middle part of which is pivotally connected to the upper cover plate 22. The front end of the rotating part 311 is inclined upward to prevent the bar box 200 from colliding with the bar box 200 when it enters the channel 10.
[0052] Optionally, the rotating part 311 further includes a columnar part 312, which protrudes from one end of the rotating part 311, and the periphery of the columnar part 312 can abut against the carton 200. With the above arrangement, since the periphery of the columnar part 312 is an arc-shaped surface, when it comes into contact with the surface of the carton 200, the opening on the front side is large, and the carton 200 gradually comes into contact with the lowest side of the columnar part 312, thus avoiding a hard collision between the carton 200 and the columnar part 312.
[0053] Optionally, M rows of cigarette packs are arranged side-by-side along the second direction inside the carton 200. M first clamping components 30 are arranged along the second direction, corresponding one-to-one with each of the M rows of cigarette packs. Specifically, M = 5, and each row contains two cigarette packs. This arrangement ensures that each row of cigarette packs has a first clamping component 30 above it, meaning each row has a rotating component 31 clamping it, ensuring balanced force on each row and preventing any shifting.
[0054] Alternatively, see also Figure 3 The carton forming channel also includes a plurality of first rollers 40, which are spaced apart along the second direction and correspond to the first clamping assembly 30. The first rollers 40 are pivotally connected to the base plate 24. With the above arrangement, while the carton 200 is clamped by the plurality of first clamping assemblies 30 above at this position, the lower part of the channel 10 is also compressed due to the arrangement of the first rollers 40, so that the lower side of the carton 200 also has a certain clamping force, so that both the upper and lower layers of cigarette packs are clamped, preventing uneven force on the two layers of cigarette packs.
[0055] Optionally, the number of the first rollers 40 is also set to M, specifically five, corresponding to the five rows of cigarette packets, ensuring that the lower side of each row of cigarette packets is clamped.
[0056] Optionally, the upper cover plate 22 further comprises a base plate 222 spaced apart from the cover plate body 221 in the third direction (Z direction in the figure, which is perpendicular to the X direction and the Y direction respectively), and the spacing between the cover plate body 221 and the base plate 222 is adjustable. Through the above arrangement, the size of the channel 10 in the third direction can be adjusted.
[0057] It should be noted that the base plate 222 can be hinged with other parts, so that the upper side of the channel 10 can be opened or closed; or the base plate 222 can be fixedly connected with the left side plate 21 and the right side plate 23, which is not limited here.
[0058] Specifically, one of the base plate 222 and the cover plate body 221 is provided with a threaded stud 223, and the other is threadedly connected with the threaded stud 223, and the threaded stud 223 is locked by a nut. By adjusting the position of the nut, the spacing between the two is adjusted.
[0059] Optionally, as shown in Figure 3 , the carton forming channel further comprises a second clamping assembly 50 arranged at the outlet of the channel 10. The second clamping assembly 50 has the same structure as the first clamping assembly 30, and a plurality of second rollers (obscured in the figure, not numbered) are arranged below the second clamping assembly 50 and spaced apart in the second direction. Each second roller is pivotally connected with the bottom plate 24. It can be understood that the second clamping assembly 50 and the second roller have the same structure as the first clamping assembly 30 and the first roller 40, and are arranged at the outlet of the channel 10, which can prevent the carton 200 from moving when it is rejected due to the disappearance of the lateral extrusion force at the outlet.
[0060] Optionally, as shown in Figure 8 , the left side plate 21 and the right side plate 23 are symmetrically arranged, and the right side plate 23 comprises a guide piece 231 and a bending piece 232. The guide piece 231 is provided with a relief groove 2311 for the side plate 220 of the carton 200 to pass through. The bending piece 232 is located downstream of the guide piece 231, and the front end of the bending piece 232 is inclined downward from the bottom to the top. It can be understood that when passing through the guide piece 231, the two side plates 220 of the carton 200 have not been folded, so the guide piece 231 needs to be slotted to avoid interference. When the carton 200 is pressed backward by the next carton 200, the side plate 220 is gradually folded in place due to the inclined surface of the bending piece 232.
[0061] Optionally, as shown in Figure 8As shown, the carton forming channel further comprises a sensing assembly 60 arranged at the front end of the channel 10 and configured to detect the length of the carton 200 in the second direction, and a rejecter in communication connection with the sensing assembly 60. Through the above arrangement, whether the size of the carton 200 in the second direction is qualified can be detected before entering the channel 10, and if not qualified, the carton can be rejected at the subsequent station, so as to prevent the defective product from entering the subsequent process.
[0062] Further, the sensing assembly 60 comprises two sensing members 61 arranged oppositely and configured to measure the size of the carton 200 in the second direction by the way of transmission.
[0063] The embodiment further provides a carton packaging machine comprising the carton forming channel. The carton packaging machine has a higher qualified rate of the formed carton 200 by adopting the carton forming channel.
[0064] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is unnecessary and impossible to enumerate all the implementation modes. Any modification, equivalent substitution and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
