Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging equipment technology, and in particular to the paper receiving column connection structure. Background Technology

[0002] Sealing paper is a key auxiliary material used for sealing cigarette packs in the tobacco packaging industry. Its core function is to achieve sealing, anti-counterfeiting, and brand identification of the cigarette pack. The paper receiving rail connection structure of the sealing paper transmits the execution power of the equipment to the paper receiving rail. The paper receiving rail connection structure includes a transmission component and a horizontal connecting rod connecting the transmission component and the paper receiving rail. The transmission component can drive the connecting rod to reciprocate back and forth, thereby driving the paper receiving rail to reciprocate back and forth. When the paper receiving rail moves to the rear end, the sealing paper is received. When the paper receiving rail moves to the front end, it sends the sealing paper to the suction fork position. The suction fork has negative pressure suction to suck up the sealing paper. After the suction fork rotates 90 degrees, it reaches the top position of the cigarette pack. The push rod pushes the cigarette pack and the sealing paper together into the cigarette pack forming channel, completing the affixing of the sealing paper.

[0003] Currently, after the sealing paper is coated with adhesive, it is conveyed to the receiving tray. Long-term operation of the equipment can easily lead to the accumulation of adhesive residue and dirt in the receiving tray, causing malfunctions such as misalignment and blockage during sealing paper conveying. Maintenance of the receiving tray is necessary. Cleaning directly on the equipment is time-consuming and requires limited operating space. Disassembling the receiving tray for cleaning and reinstalling it on the connecting rod can easily cause positional deviations, similarly leading to problems such as uneven sealing paper length, misalignment, and blockage, requiring adjustments by maintenance personnel. Adjusting the sealing paper length involves removing the receiving tray and adjusting the height of the positioning block by adding or removing shims between the bottom positioning block and the receiving tray seat. This process is time-consuming and labor-intensive, generates a large number of defective cigarette packs, reduces the effective operating rate of the equipment, and wastes raw materials.

[0004] Therefore, a paper receiving frame connection structure is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a paper receiving frame connection structure to avoid unnecessary installation errors caused by operators disassembling the paper receiving frame, adapt to different sizes of sealing paper or handle faults, reduce the production of substandard cigarette packs, save adjustment time, and improve work efficiency and the utilization rate of sealing paper.

The movable end of the transmission assembly is detachably and fixedly connected to the first end of the first connector via the positioning fastener. Movement of the movable end of the transmission assembly can drive the connecting assembly to move along a first direction. The first end of the second connector is connected to the paper receiving column, and the second end of the second connector is slidably connected to the second end of the first connector. The second connector can slide and lock relative to the first connector along a second direction, so that the position of the paper receiving column along the second direction is adjustable.

[0010] As an alternative solution for the paper receiving column connection structure, the second end of the first connector has a convex shape, and the second end of the second connector has a concave shape that cooperates with the convex shape. The concave shape can be embedded in the convex shape, and the concave shape can slide and lock relative to the convex shape along the second direction.

[0011] As an alternative solution to the paper receiving tray connection structure, the connection assembly further includes a first guide fastener. The second end of the second connector is provided with a first oblong hole extending along the second direction. The first guide fastener can pass through the first oblong hole and connect to the second end of the first connector. When the second connector moves relative to the first connector along the second direction, the first guide fastener slides in the first oblong hole, and the first guide fastener is configured to lock the relative position between the first connector and the second connector.

[0012] As an alternative solution for the paper feeder connection structure, the second end of the first connector is provided with a scale extending along the second direction, and the second end of the second connector is provided with a pointer that points to the scale, so that the adjustment amount of the paper feeder along the second direction is visualized.

[0013] As an alternative to the paper feeder connection structure, the pointer is coated with a fluorescent coating.

[0014] As an alternative solution to the paper receiving tray connection structure, the transmission assembly includes:

[0015] A cam, a roller, and a drive rod, wherein the cam rotates and abuts against the first end of the drive rod via the roller;

[0016] A sector-shaped tooth is fixed at the second end of the transmission rod;

[0017] A drive shaft extends along the first direction, and the end of the drive shaft is connected to the first end of the first connector via the positioning fastener;

[0018] A rack is fixed on the drive shaft along its axial direction. The sector teeth mesh with the rack. The rotation of the cam can drive the drive rod to swing, causing the sector teeth to swing synchronously, so that the rack moves along the axial direction of the drive shaft, so that the drive shaft moves along the first direction.

[0019] As an optional solution for the paper receiving tray connection structure, the first end of the first connector is provided with a positioning groove, and the end of the drive shaft is provided with a positioning protrusion that cooperates with the positioning groove. The positioning protrusion can be inserted into the positioning groove to fix the relative position of the first connector and the drive shaft.

The second guide fastener is configured to lock the relative position between the paper receiving tray and the second connector. The first direction, the second direction, and the third direction are all perpendicular to each other.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] This embodiment discloses a paper receiving column connection structure, such as Figures 1-3As shown, the paper receiving rail connection structure is used to connect the paper receiving rail 100, which is used to receive sealing paper. The paper receiving rail connection structure includes a transmission component 1 and a connecting component 2. The connecting component 2 includes a first connecting member 21, a second connecting member 22, and a positioning fastener 23. The movable end of the transmission component 1 is detachably and fixedly connected to the first end of the first connecting member 21 through the positioning fastener 23. The movement of the movable end of the transmission component 1 can drive the connecting component 2 to move along a first direction. The first end of the second connecting member 22 is connected to the paper receiving rail 100, and the second end of the second connecting member 22 is slidably connected to the second end of the first connecting member 21. The second connecting member 22 can slide and lock relative to the first connecting member 21 along a second direction, so that the position of the paper receiving rail 100 along the second direction is adjustable. The second direction is the height direction of the paper receiving rail 100. The first direction and the second direction are perpendicular to each other.

[0044] When the paper receiving frame connection structure is in operation, the movement of the movable end of the transmission component 1 can drive the connecting component 2 to move along the first direction, thereby driving the paper receiving frame 100 connected to the first end of the second connecting member 22 to move synchronously along the first direction to adapt to the sealing paper receiving requirements. The positioning fastener 23 can realize the convenient disassembly and assembly of the transmission component 1 and the first connecting member 21 to avoid positional deviation. When it is necessary to adjust the height of the paper receiving frame 100, the second connecting member 22 can slide relative to the first connecting member 21 along the second direction, and lock it after adjusting to the appropriate position. There is no need to disassemble the paper receiving frame 100, which reduces the number of defective cigarette packs, saves time, and improves the operating efficiency of the equipment. This paper receiving tray connection structure avoids unnecessary installation errors caused by operators disassembling the paper receiving tray 100, ensuring that the first connecting piece 21 can be installed in place after disassembly and maintenance, and preventing positional deviation of the paper receiving tray 100. There is no need to add or remove shims between the bottom positioning block of the paper receiving tray 100 and the paper receiving tray seat to adjust the height of the sealing paper in the paper receiving tray 100. The height of the paper receiving tray 100 can be adjusted by sliding the second connecting piece 22, which can adapt to different sizes of sealing paper or handle faults, reduce the generation of defective cigarette packs, save adjustment time, and improve work efficiency and the utilization rate of sealing paper.

[0045] It is worth noting that the positioning fastener 23 is located on the side that is easy to disassemble, making it easier to disassemble and assemble the transmission component 1 and the first connecting piece 21. This ensures that the position of the paper receiving column 100 can be adjusted flexibly and improves maintenance and assembly efficiency.

[0046] like Figures 3-4As shown, the second end of the first connector 21 has a convex U-shaped structure, and the second end of the second connector 22 has a concave U-shaped structure that cooperates with the convex U-shaped structure. The concave U-shaped structure can be embedded in the convex U-shaped structure, and the concave U-shaped structure can slide and lock relative to the convex U-shaped structure along the second direction. When adjusting the height of the paper receiving column 100, the concave U-shaped structure at the second end of the second connector 22 can slide relative to the convex U-shaped structure at the second end of the first connector 21 along the second direction, and lock after entering the position. The cooperation of the convex and concave structures ensures stable sliding, which not only flexibly adjusts the position of the paper receiving column 100, but also ensures the stability of the receiving, improving the adaptability and ease of operation of the paper receiving column connection structure.

[0047] like Figures 3-4 As shown, the connecting assembly 2 also includes a first guide fastener 24. The second end of the second connector 22 has a first oblong hole 221 extending in a second direction. The first guide fastener 24 passes through the first oblong hole 221 and connects to the second end of the first connector 21. When the second connector 22 moves relative to the first connector 21 in the second direction, the first guide fastener 24 slides within the first oblong hole 221, and the first guide fastener 24 is used to lock the relative position between the first connector 21 and the second connector 22. When adjusting the height of the paper receiving tray 100, the first guide fastener 24 is loosened, and the second connector 22 can move in the second direction. At this time, the first guide fastener 24 slides within the first oblong hole 221 of the second connector 22. After adjustment, the first guide fastener 24 is tightened to lock the relative position between the first connector 21 and the second connector 22. Through the cooperation of the first oblong hole 221 and the first guide fastener 24, the height of the paper receiving tray 100 is stably adjusted, and the operation is simple, ensuring reliable sealing of the paper.

[0048] like Figures 3-4 As shown, the second end of the first connector 21 is provided with a scale 213 extending along the second direction, and the second end of the second connector 22 is provided with a pointer 222, which points to the scale 213, so that the adjustment amount of the paper receiving column 100 along the second direction is visualized. When adjusting the height of the paper receiving column 100, the first guide fastener 24 is loosened, and the second connector 22 slides along the second direction. The pointer 222 at the second end of the second connector 22 will move with the second connector 22 and point to the scale 213 at the second end of the first connector 21, making it easy to read the adjustment amount intuitively. After reaching the position, the first guide fastener 24 is tightened to lock it. The adjustment amount is visualized through the scale 213 and the pointer 222, which improves the accuracy and efficiency of the height adjustment of the paper receiving column 100 and ensures accurate sealing of the paper.

[0049] In this embodiment, the pointer 222 is coated with a fluorescent coating. When adjusting the height of the paper receiving tray 100, the first guide fastener 24 is loosened, and the second connector 22 slides along the second direction. The pointer 222, coated with a fluorescent coating on the second end of the second connector 22, will point to the scale 213 of the first connector 21. The adjustment amount can be read intuitively even in low-light environments. After reaching the desired position, the first guide fastener 24 is tightened to lock it in place. The fluorescent coating makes the pointer 222 conspicuous in low-light scenes, unaffected by light, improving the convenience and accuracy of adjusting the height of the paper receiving tray 100 and ensuring stable sealing of the paper.

[0050] like Figures 1-2 As shown, the transmission assembly 1 includes a cam 11, a roller, a transmission rod 12, a sector tooth 13, a transmission shaft 14, and a rack 15. The cam 11 rotates and abuts against the first end of the transmission rod 12 via the roller. The sector tooth 13 is fixed to the second end of the transmission rod 12. The transmission shaft 14 extends along a first direction, and the end of the transmission shaft 14 is connected to the first end of the first connecting member 21 via a positioning fastener 23. A rack 15 is fixed on the transmission shaft 14 along its axial direction. The sector tooth 13 meshes with the rack 15. The rotation of the cam 11 can drive the transmission rod 12 to swing, which in turn drives the sector tooth 13 to swing synchronously, so that the rack 15 moves along the axial direction of the transmission shaft 14, thereby moving the transmission shaft 14 along the first direction. The rotation of cam 11 drives the transmission rod 12 to swing through the roller, causing the sector tooth 13 fixed at the second end of the transmission rod 12 to swing synchronously. The sector tooth 13 meshes with the rack 15 on the transmission shaft 14, thereby driving the rack 15 to move axially along the transmission shaft 14, allowing the transmission shaft 14 to move along the first direction. The movement of the transmission shaft 14 drives the connecting component 2 and the paper receiving column 100 to move along the first direction to adapt to the receiving of the sealing paper, realizing stable transmission of the paper receiving column 100 along the first direction. The structure and transmission are precise, ensuring the reliable receiving position of the sealing paper and improving the overall operational stability.

[0051] like Figure 3 As shown, the first end of the first connecting member 21 is provided with a positioning groove 211, and the end of the drive shaft 14 is provided with a positioning protrusion 141 that cooperates with the positioning groove 211. The positioning protrusion 141 can be inserted into the positioning groove 211 to fix the relative position of the first connecting member 21 and the drive shaft 14. The positioning protrusion 141 at the end of the drive shaft 14 first inserts into the positioning groove 211 at the first end of the first connecting member 21 to quickly fix the relative position of the two, and then is reinforced with the positioning fastener 23. The cooperation between the positioning protrusion 141 and the positioning groove 211 simplifies the assembly and positioning steps of the drive shaft 14 and the first connecting member 21, improves assembly efficiency, and at the same time ensures stable connection between the two during transmission, ensuring accurate movement of the paper receiving tray 100.

[0052] like Figure 1 and Figure 3As shown, the positioning fastener 23 is a positioning pin with external threads. The first end of the first connector 21 has a first positioning hole 212, and the end of the drive shaft 14 has a second positioning hole with internal threads that mate with the external threads. The positioning pin can pass through the first positioning hole 212 and be threadedly connected to the second positioning hole, so that the relative positions of the first connector 21 and the drive shaft 14 are fixed, and the two can be detachably connected. First, the positioning protrusion 141 at the end of the drive shaft 14 is inserted into the positioning groove 211 of the first connector 21. Then, the positioning pin with external threads is passed through the first positioning hole 212 of the first connector 21 and threadedly connected to the second positioning hole of the drive shaft 14, fixing the positions of the drive shaft 14 and the first connector 21. The threaded positioning pin is easy to install and remove, ensuring a stable connection during transmission, improving assembly and maintenance efficiency, and ensuring the precise movement of the paper receiving tray 100.

[0053] like Figures 1-3 As shown, the connecting component 2 also includes a second guide fastener 25. The paper receiving column 100 is provided with a second waist-shaped hole 101 extending along a third direction, which is the width direction of the paper receiving column 100. The second guide fastener 25 can pass through the second waist-shaped hole 101 and connect to the first end of the second connector 22. When the paper receiving column 100 moves relative to the second connector 22 along the third direction, the second guide fastener 25 slides in the second waist-shaped hole 101. The second guide fastener 25 is used to lock the relative position between the paper receiving column 100 and the second connector 22. The first direction, the second direction, and the third direction are perpendicular to each other. When the sealing paper needs to be positioned along its width, the second guide fastener 25 is loosened, and the paper receiving column 100 can move along the third direction. At this time, the second guide fastener 25 slides in the second oblong hole 101 of the paper receiving column 100. After it is in place, it is tightened and locked, so that the paper receiving column 100 can be flexibly adjusted in the first direction, the second direction, and the third direction, which are perpendicular to each other, to adapt to different specifications of sealing paper, ensure accurate and stable reception, and facilitate operation.

[0054] In this embodiment, the paper receiving tray connection structure also includes a buffer pad, which is disposed on the receiving surface of the paper receiving tray 100. When the sealing paper falls onto the receiving surface of the paper receiving tray 100, the buffer pad on the receiving surface can reduce the impact, avoid direct hard contact between the sealing paper and the paper receiving tray 100, prevent wear on the edges of the sealing paper or wrinkles caused by collision, ensure the integrity of the sealing paper after receiving, and make the receiving process more stable, thereby improving the overall work quality.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
