Description

Technical Field

[0001] This utility model relates to the field of cigarette label paper packaging technology, specifically to a label paper packaging cutting device and packaging production line. Background Technology

[0002] In the cigarette packaging industry, the label paper used to package loose cigarettes is usually stored in fixed stacks and secured with strips of kraft paper.

[0003] During cigarette packaging, the kraft paper straps binding the stacks of labels need to be removed before they can be fed into the packaging machine for cigarette packaging. This process is usually done manually. Workers lift the stacks of labels, use paper cutters to cut and peel off the binding kraft paper straps, and then put the bare stacks of labels onto the packaging machine conveyor belt.

[0004] However, the traditional manual removal method has significant drawbacks. The stack of labels is large and heavy, and workers are prone to muscle strain after repeatedly moving the stacks of labels, which causes the removal efficiency to gradually decrease as the working time increases. Consequently, it cannot match the operating rhythm of high-speed packaging machines, forcing a reduction in cigarette packaging speed. Utility Model Content

[0005] The purpose of this invention is to overcome the problem that the kraft paper straps used to manually remove the label paper stacks cannot match the operating rhythm of high-speed packaging machines, thus reducing the efficiency of cigarette packaging.

The cleaning mechanism is mounted on the frame portion and configured to clean the kraft paper strips released by the peeling mechanism out of the conveying mechanism.

[0007] In some embodiments, the cutting mechanism includes a pushing mechanism and an insertion plate. The pushing mechanism is mounted on a mounting frame and connected to the insertion plate. The insertion plate is equipped with a cutting blade for cutting the kraft paper strip. The insertion plate is capable of being inserted into the gap between the label paper stack and the kraft paper strip under the drive of the pushing mechanism and retracting after cutting the kraft paper strip.

[0008] In some embodiments, the cutting blade is vertically mounted on the top surface of the insertion plate, and the length direction of the cutting blade is parallel to the conveying direction of the conveying section; and the distance between the cutting edge of the cutting blade and the top surface of the insertion plate gradually increases from the beginning end to the end end of the cutting blade.

[0009] In some embodiments, the cutting mechanism includes a drive motor, a guide rod, a first lead screw, and a cutting blade threaded to the first lead screw; the first lead screw and the guide rod are mounted parallel to each other on a mounting frame, the drive motor is connected to the first lead screw, the drive motor can drive the first lead screw to rotate so that the cutting blade reciprocates, the cutting blade is slidably connected to the guide rod, the cutting blade is located above the stack of label paper and is used to cut kraft paper strips.

[0010] In some embodiments, the peeling mechanism includes a moving mechanism, a gripping plate, and a vacuum suction cup assembly; the moving mechanism is mounted on the frame portion, connected to the gripping plate, and capable of moving the gripping plate in a direction toward or away from the kraft paper strip; the vacuum suction cup assembly is mounted on the gripping plate and is capable of gripping or releasing the kraft paper strip.

[0011] In some embodiments, the number of gripping plates is set to two, with the two gripping plates spaced apart in the width direction of the rack portion and facing each other.

[0012] In some embodiments, the moving mechanism includes a driver, two sliding plates, a second lead screw, and a guide rod. The second lead screw and the guide rod are mounted parallel to each other on the frame portion and located below the conveying portion. A gripping plate is mounted on the side of the sliding plates facing the conveying portion. The two sliding plates are slidably connected to the guide rod, respectively. The second lead screw has a first thread extending from one end to its middle portion and a second thread extending from its other end to its middle portion. The first thread and the second thread have opposite helical directions. The two sliding plates are threadedly connected to the portion of the second lead screw with the first thread and the portion of the second lead screw with the second thread, respectively. The driver is connected to one end of the second lead screw.

[0013] In some embodiments, a second connecting rod is vertically mounted on the side of the sliding plate facing the conveying portion.

[0017] Workers linearly arrange multiple stacks of trademark paper on the conveyor section of the conveyor mechanism, ensuring the width of the kraft paper strip is parallel to the conveying direction. These stacks of trademark paper on the conveyor section pass sequentially through the mounting frame. When each stack of trademark paper reaches the cutting position at the mounting frame, the cutting mechanism cuts the kraft paper strip binding the stack. Then, a peeling mechanism secures the cut kraft paper strip, and the stack of trademark paper with the cut kraft paper strip continues to be conveyed forward by the conveyor section, thus completely separating the kraft paper strip from the stack of trademark paper. After separation, the peeling mechanism releases the kraft paper strip, allowing it to continue to be conveyed forward by the conveyor section of the same mechanism. When it reaches the cleaning position of the cleaning mechanism, the cleaning mechanism removes it from the conveyor mechanism. Therefore, the trademark paper packaging cutting device of this utility model can replace manual cutting of kraft paper strips by a cutting mechanism, and then peeling the kraft paper strips off the trademark paper stack by a peeling mechanism. It eliminates the need for manual cutting and peeling of kraft paper strips, and solves the problem of reduced cigarette packaging efficiency caused by manual removal of kraft paper strips not being able to match the operating rhythm of high-speed packaging machines.

Detailed Implementation

[0025] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] like Figure 1 and Figure 4As shown, this utility model provides a trademark paper packaging cutting device. The trademark paper packaging cutting device includes a mounting frame 1, a conveying mechanism 2, a cutting mechanism 3, a peeling mechanism 4, and a cleaning mechanism 5. The conveying mechanism 2 includes a frame portion 21 and a conveying portion 22, the conveying portion 22 being mounted on the frame portion 21 and used to convey a stack of trademark paper 6. The mounting frame 1 is mounted on the frame portion 21, and the cutting mechanism 3 is mounted on the mounting frame 1 and located directly above the conveying portion 22. The cutting mechanism 3 is used to cut the kraft paper strips of the stack of trademark paper 6. The peeling mechanism 4 is mounted on the frame portion 21 and is configured to grasp the cut kraft paper strips to peel them off from the stack of trademark paper 6 and to release the peeled kraft paper strips. The cleaning mechanism 5 is mounted on the frame portion 21 and is configured to clean the kraft paper strips released by the peeling mechanism 4 out of the conveying mechanism 2.

[0029] Specifically, workers linearly arrange multiple stacks 6 of trademark paper on the conveying section 22 of the conveying mechanism 2, ensuring the width of the kraft paper strip is parallel to the conveying direction of the conveying section 22. These stacks 6 of trademark paper on the conveying section 22 pass sequentially through the mounting frame 1. When each stack 6 of trademark paper reaches the cutting position at the mounting frame 1, the cutting mechanism 3 cuts the kraft paper strip binding the stack 6. Then, the peeling mechanism 4 secures the cut kraft paper strip, and the stack 6 of trademark paper with the cut kraft paper strip continues to be transported forward by the conveying section 22, thus completely separating the kraft paper strip from the stack 6 of trademark paper. After the kraft paper strip is separated from the stack 6 of trademark paper, the peeling mechanism 4 releases the kraft paper strip, allowing it to continue to be transported forward by the conveying section 22 of the conveying mechanism 2. When it reaches the cleaning position of the cleaning mechanism 5, the cleaning mechanism 5 removes it from the conveying mechanism 2. Therefore, the trademark paper packaging cutting device of this utility model can replace manual cutting of kraft paper strips by cutting mechanism 3, and then peeling kraft paper strips off trademark paper stack 6 by peeling mechanism 4. It eliminates the need for manual cutting and peeling of kraft paper strips, and solves the problem of reduced cigarette packaging efficiency caused by manual removal of kraft paper strips not being able to match the operating rhythm of high-speed packaging machines.

[0030] like Figure 3 As shown, in some embodiments of this utility model, the cutting mechanism 3 includes a pushing mechanism and an insertion plate 31. The pushing mechanism is mounted on the mounting frame 1 and connected to the insertion plate 31. The insertion plate 31 is equipped with a cutting blade 32 for cutting the kraft paper strip. The insertion plate 31 can be inserted into the gap between the trademark paper stack 6 and the kraft paper strip under the drive of the pushing mechanism and retract after cutting the kraft paper strip.

[0031] Specifically, when the stack of trademark paper 6 reaches the cutting position below the mounting frame 1, the conveying part 22 of the conveying mechanism 2 immediately stops working, leaving the stack of trademark paper 6 stationary in the cutting position to await cutting by the cutting mechanism 3. Driven by the pushing mechanism, the insertion plate 31 moves towards the stack of trademark paper 6. Due to the high rigidity of the kraft paper strip, it arches away from the stack of trademark paper 6, forming a gap between the stack of trademark paper 6 and the kraft paper strip. The bottom surface of the insertion plate 31 is pressed against the plane of the stack of trademark paper 6 and inserts itself into the gap between the stack of trademark paper 6 and the kraft paper strip; after the insertion plate 31 enters the gap, the cutting blade 32 on the insertion plate 31 begins to cut the kraft paper strip. When the kraft paper strip is completely cut, the insertion plate 31 can retract under the drive of the pushing mechanism to return to its original position to await cutting the next stack of trademark paper 6.

[0032] It should be noted that the pushing mechanism can adopt various structural forms such as cylinders, hydraulic cylinders, electric rails, etc., which can drive the insertion plate 31 to move back and forth. Those skilled in the art can choose according to their needs, and this utility model does not impose any restrictions.

[0033] In some embodiments of this utility model, the cutting blade 32 is vertically mounted on the top surface of the insertion plate 31, and the length direction of the cutting blade 32 is parallel to the conveying direction of the conveying section 22; and in the direction from the starting end to the end of the cutting blade 32, the distance between the cutting edge of the cutting blade 32 and the top surface of the insertion plate 31 gradually increases.

[0034] Specifically, the starting end of the cutting blade 32 is the end that first contacts the kraft paper strip when cutting it. When the insert plate 31 just enters the gap between the label paper stack 6 and the kraft paper strip, the gap is small, and the blade at the starting end of the cutting blade 32 is close to the insert plate 31, making it more adaptable to this small gap. As the kraft paper strip begins to be cut, the gap gradually widens, and the blade of the cutting blade 32 is raised adaptively to accommodate this gap, which helps to accelerate the cutting process.

[0035] like Figure 2 As shown, in some embodiments of this utility model, the cutting mechanism 3 includes a drive motor 34, a guide rod 35, a first lead screw 33, and a cutting blade 32 threadedly connected to the first lead screw 33; the first lead screw 33 and the guide rod 35 are mounted parallel to each other on the mounting frame 1, the drive motor 34 is connected to the first lead screw 33, the drive motor 34 can drive the first lead screw 33 to rotate so that the cutting blade 32 reciprocates, the cutting blade 32 is slidably connected to the guide rod 35, the cutting blade 32 is located above the label paper stack 6 and is used to cut kraft paper strips.

[0036] Specifically, driven by the drive motor 34, the first lead screw 33 rotates forward or reverse, enabling the cutting blade 32 to move toward or away from the cutting position. Since the number of trademark sheets in the trademark sheet stack 6 is fixed, the height of each trademark sheet stack 6 is the same. Therefore, the cutting blade 32 does not need to be adjusted in height when cutting the kraft paper strip. It only needs to move horizontally in the plane above the top trademark sheet of the trademark sheet stack 6 to cut the kraft paper strip.

[0037] In some embodiments, the cutting blade 32 extends from its side toward the label paper stack 6 to its bottom.

[0038] In some embodiments of this utility model, the peeling mechanism 4 includes a moving mechanism 41, a gripping plate 42, and a vacuum suction cup assembly 421; the moving mechanism 41 is mounted on the frame portion 21, the moving mechanism 41 is connected to the gripping plate 42 and can make the gripping plate 42 move in a direction toward or away from the kraft paper strip; the vacuum suction cup assembly 421 is mounted on the gripping plate 42 and can grip or release the kraft paper strip.

[0039] Specifically, the gripping plate 42 moves towards the kraft paper strip, and the vacuum suction cup assembly 421 on the gripping plate 42 can stably adsorb the kraft paper strip. Then, the gripping plate 42 moves away from the kraft paper strip, allowing the label paper stack 6 to continue moving forward, thereby peeling off the kraft paper strip. After peeling is completed, the vacuum suction cup assembly 421 releases air, releasing the kraft paper strip, allowing it to move forward and be cleaned by the cleaning mechanism 5.

[0040] It should be noted that those skilled in the art can choose the vacuum suction cup assembly 421 as needed, and this utility model does not impose any restrictions.

[0041] In some embodiments of this utility model, the number of gripping plates 42 is set to two, and the two gripping plates 42 are spaced apart in the width direction of the frame portion 21 and face each other.

[0042] Specifically, after the cutting blade 32 cuts the kraft paper strip, the two gripping plates 42 located on both sides of the trademark paper stack 6 can respectively fix the two ends formed by the cut kraft paper strip, thereby separating the kraft paper strip from the trademark paper stack 6.

[0043] In some embodiments of this utility model, the moving mechanism 41 includes a driver 48, two sliding plates 43, a second lead screw 44, and a guide rod 45. The second lead screw 44 and the guide rod 45 are installed parallel to each other on the frame portion 21 and located below the conveying portion 22. The gripping plate 42 is installed on the side of the sliding plate 43 facing the conveying portion 22. The two sliding plates 43 are slidably connected to the guide rod 45 respectively. The second lead screw 44 has a first thread extending from one end to its middle portion and a second thread extending from its other end to its middle portion. The helical directions of the first thread and the second thread are opposite. The two sliding plates 43 are threadedly connected to the portion of the second lead screw 44 with the first thread and the portion of the second lead screw 44 with the second thread respectively. The driver 48 is connected to one end of the second lead screw 44.

[0044] Specifically, when peeling off the kraft paper strip, the actuator 48 causes the second lead screw 44 to rotate forward, thereby causing the two sliding plates 43 to move towards each other. This causes the gripping plate 42, connected to the sliding plate 43, to press against the part of the label paper stack 6 where the kraft paper strip is bound. The vacuum suction cup assembly 421 draws air to fix the kraft paper strip. The actuator 48 then causes the second lead screw 44 to rotate in reverse, causing the two sliding plates 43 to move away from each other. This causes the gripping plate 42 to move both ends of the kraft paper strip away from the label paper stack 6, and the label paper stack 6 moves forward, thus separating the two. After separation, the vacuum suction cup assembly 421 releases air to release the kraft paper strip, which continues to move forward and is processed by the cleaning mechanism 5.

[0045] like Figure 5 As shown, in some embodiments, the driver 48 may be a motor that is directly connected to the second lead screw 44.

[0046] In some embodiments, the driver 48 includes a first connecting rod 7, a rack 71, a first gear 72, and a belt drive structure 73. One end of the first connecting rod 7 is fixedly connected to the cutting blade 32, and the other end is connected to the rack 71, which is slidably connected to the mounting frame 1. The drive shaft of the belt drive structure 73 is rotatably mounted on the mounting frame 1, and the first gear 72 is sleeved on it, meshing with the rack 71. The driven shaft of the belt drive structure 73 is connected to the second lead screw 44. When the cutting blade 32 moves along the first lead screw 33, the first connecting rod 7 drives the rack 71 to move, thereby causing the drive shaft of the belt drive structure 73 with the first gear 72 to rotate, which in turn causes the second lead screw 44 to rotate under the drive of the belt drive structure 73. Furthermore, when the cutting blade 32 cuts the kraft paper strip, the second lead screw 44 rotates forward, causing the gripping plate 42 to move towards the label paper stack 6; when the cutting blade 32 finishes cutting and retracts in the reverse direction, the second lead screw 44 rotates in the reverse direction, and the gripping plate 42 moves away from the label paper stack 6. On the other hand, the cutting blade 32 is slidably connected to the mounting bracket 1 through the first connecting rod 7 and the rack 71, so that the first connecting rod 7 and the rack 71 play the same guiding role as the guide rod 35.

[0047] In some embodiments of this utility model, a second connecting rod 46 is vertically installed on the side of the sliding plate 43 facing the conveying part 22. The second connecting rod 46 is connected to the gripping plate 42 by a spring, and a guide tube 47 is sleeved on the outside of the spring. The guide tube 47 is fixedly connected to the sliding plate 43, and one end of the second connecting rod 46 facing the conveying part 22 is movably inserted into the guide tube 47.

[0048] Specifically, after the two gripping plates 42 come into contact with the kraft paper strips bound to both sides of the trademark paper stack 6, the two gripping plates 42 continue to move towards each other. The spring is compressed, which causes the sides of the kraft paper strip that are in contact with the gripping plates 42 to be squeezed, thereby deforming the kraft paper strip and causing the top of the strip to be cut to arch up, making it easier for the cutting blade 32 to cut.

[0049] In some embodiments of this utility model, the cleaning mechanism 5 includes a push-pull mechanism, a push plate 51, and a collection box 52. The collection box 52 is disposed on one side of the frame portion 21. The push-pull mechanism is installed on the frame portion 21, and the push plate 51 is connected to the push-pull mechanism. The push-pull mechanism can push and pull the push plate 51 so that the push plate 51 can move toward or away from the collection box 52.

[0050] Specifically, a vision sensor is installed on the push plate 51. When the vision sensor detects that the kraft paper strip has reached the cleaning position, the vision sensor will send a control signal to drive the push plate 51 to push the kraft paper strip into the collection box 52.

[0051] In another aspect, this utility model provides a packaging production line that includes the trademark paper packaging cutting device in the above embodiments, and also has all the advantages of the above embodiments.

[0053] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0054] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
