Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and more specifically to a device for splicing transparent paper in cigarette packs. Background Technology

[0002] The cigarette pack transparent paper splicing device is a key piece of equipment on the cigarette packaging production line. It is mainly used to achieve seamless splicing of transparent films (such as BOPP, PVC, etc.), ensure continuous material supply during the packaging process, and avoid production efficiency being affected by downtime due to roll changing. Its core functions include automatic detection of film roll remaining amount, precise positioning of splicing position, hot melt or adhesive bonding, and tension control to keep the film flat.

[0003] However, in actual use, especially when the transparent paper roll is about to run out and needs to be replaced, the detector sends a signal to stop the equipment. The operator then pulls the handle to press the swing arm down, and the two layers of transparent paper are heat-fused together by a soldering iron. The transparent paper strip on the side that is about to run out is then cut manually, the handle is released, and the tension of the spring returns the swing arm to the vertical position, thus completing one manual transparent paper splicing process.

[0004] Although this manual splicing method is simple to operate, it requires operators to constantly observe the use of the transparent paper. Moreover, each time the machine is stopped to replace the transparent paper, the upstream main machine ZB45 packaging machine will be shut down for about 2 minutes, which affects the effective operating rate of the equipment. Frequent shutdowns not only accelerate equipment wear and shorten the service life of the equipment, but also cause a certain degree of waste of raw materials and increase production costs.

[0005] Therefore, how to provide a device for splicing transparent paper in cigarette packs has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cigarette pack transparent paper splicing device to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a cigarette pack transparent paper splicing device, including a main support plate, an upper splicing plate movably connected to one side of the main support plate, a lower splicing plate movably connected to the main support plate at the bottom of the movably connected upper splicing plate, an auxiliary support plate movably connected to the upper and lower splicing plates on the side away from the main support plate, a limiting roller provided on the adjacent side of the main support plate and the auxiliary support plate near the upper and lower splicing plates, and a pre-material shaft and a main material shaft movably connected on the adjacent side of the main support plate and the auxiliary support plate near the upper and lower splicing plates and away from the limiting roller. The main support plate and the auxiliary support plate are both movably connected to the surface of the pre-material shaft and the main material shaft. The pre-material shaft and the main material shaft are fixedly connected to the middle of the adjacent main support plate and the auxiliary support plate by the installation limit blocks. With the infrared detector, servo motor and bidirectional screw provided, when the transparent paper is used to the end and no longer covers the top of the infrared detector, the servo motor receives the signal and drives the bidirectional screw to rotate. This causes the upper splicing plate and the lower splicing plate to move closer to each other and splice the new transparent paper first segment that is limited by the limiting component with the end of the original transparent paper. The whole operation does not require manual intervention and reduces the labor intensity of manual labor.

[0008] Furthermore, a splicing soldering iron is provided on the adjacent surface of the upper and lower splicing plates. Rectangular sliders are provided on both sides of the surfaces of the upper and lower splicing plates near the main support plate and the auxiliary support plate. An infrared detector is provided on the top of the lower splicing plate away from the soldering iron. An auxiliary extrusion shaft is provided on the side of the upper and lower splicing plates near the pre-material shaft and the main material shaft. With the infrared detector, servo motor, and bidirectional screw, when the transparent paper is used to the end and no longer covers the top of the infrared detector, the servo motor receives a signal and drives the bidirectional screw to rotate. This causes the upper and lower splicing plates to move closer together and splice the new transparent paper beginning segment, which is limited by the limiting component, with the end of the original transparent paper. The entire operation requires no manual intervention, reducing the labor intensity.

[0009] Furthermore, a rectangular groove is provided at the position of the infrared detector on the side of the upper splicing plate near the lower splicing plate, and a limiting groove is provided inside the side of the upper splicing plate away from the rectangular groove. A limiting component is movably connected inside the limiting groove. Lifting sliders are provided on the surface of both the upper and lower splicing plates near the main support plate. The lifting sliders facilitate the lifting and lowering of the upper and lower splicing plates.

[0010] Furthermore, the limiting component includes a rectangular extrusion plate, on one side of which are regularly arranged telescopic columns. Each telescopic column is movably connected to a spring at one end inside the upper splicing plate. The limiting component helps to fix and limit the beginning of the transparent paper to be spliced.

[0011] Furthermore, the auxiliary support plate has a second mounting groove at the position where the pre-material shaft and the main material shaft are movably connected, and a second sliding groove is provided on the surface of the auxiliary support plate where the upper splicing plate and the lower splicing plate are movably connected. A rectangular observation window is provided on the auxiliary support plate at the middle position adjacent to the second sliding groove. The auxiliary support plate helps to restrict the upper splicing plate and the lower splicing plate.

[0012] Furthermore, the main support plate has a first mounting groove at the position where it is movably connected to the pre-material shaft and the main material shaft, a first sliding groove at the position where it is movably connected to the upper splicing plate and the lower splicing plate, a lifting sliding groove at the midpoint adjacent to the first sliding groove, a bidirectional screw is movably sleeved inside the lifting sliding groove, and a servo motor is fixedly connected to the top of the main support plate. The servo motor is driven by the top of the bidirectional screw. Through the servo motor and the bidirectional screw, it is beneficial to drive the upper splicing plate and the lower splicing plate to move.

[0013] Furthermore, the mounting limiting block has regularly arranged limiting rods on one side surface near the pre-material shaft and the main material shaft.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model, by incorporating an infrared detector, a servo motor, and a bidirectional screw, facilitates the rotation of the bidirectional screw when the transparent paper reaches its end and no longer covers the top of the infrared detector. This causes the upper and lower splicing plates to move closer together, splicing the new transparent paper beginning segment, which is constrained by the limiting component, with the original transparent paper end. The entire operation requires no manual intervention, reducing the labor intensity of manual labor.

[0016] 2. This utility model, by incorporating an infrared detector, a servo motor, a bidirectional screw, and a limiting component, facilitates the reception of signals by sensing the top cover during the splicing of transparent paper, and eliminates the need to stop the machine during the splicing process, thereby improving production efficiency.

[0027] Reference Figures 1-8As shown, this utility model provides a cigarette pack transparent paper splicing device, including a main support plate 1, an upper splicing plate 2 movably connected to one side of the main support plate 1, a lower splicing plate 4 movably connected to the main support plate 1 at the bottom of the movably connected upper splicing plate 2, an auxiliary support plate 3 movably connected to the upper splicing plate 2 and the lower splicing plate 4 away from the main support plate 1, a limiting roller 5 is provided on the adjacent side of the main support plate 1 and the auxiliary support plate 3 near the upper splicing plate 2 and the lower splicing plate 4, and a pre-material shaft 6 and a main material shaft 7 are movably connected on the adjacent side of the main support plate 1 and the auxiliary support plate 3 near the upper splicing plate 2 and the lower splicing plate 4 away from the limiting roller 5. The support plate 3 is movably connected to the surface of the pre-material shaft 6 and the main material shaft 7, and the pre-material shaft 6 and the main material shaft 7 are fixedly connected to the middle of the main support plate 1 and the auxiliary support plate 3 by the installation limit blocks 8. With the infrared detector 11, servo motor 15 and bidirectional screw 16, when the transparent paper is used to the end and no longer covers the top of the infrared detector 11, the servo motor 15 receives the signal and drives the bidirectional screw 16 to rotate, so that the upper splicing plate 2 and the lower splicing plate 4 move closer to each other and splice the new transparent paper first segment that is limited by the limit component 14 with the end of the original transparent paper. The whole operation does not require manual intervention, reducing the labor intensity of manual labor.

[0028] The upper splicing plate 2 and the lower splicing plate 4 are provided with splicing soldering irons 9 on their adjacent surfaces. Rectangular sliders 10 are provided on both sides of the upper splicing plate 2 and the lower splicing plate 4 near the main support plate 1 and the auxiliary support plate 3. An infrared detector 11 is provided on the top of the lower splicing plate 4 away from the soldering iron 9. An auxiliary extrusion shaft 12 is provided on both the upper splicing plate 2 and the lower splicing plate 4 near the pre-material shaft 6 and the main material shaft 7. With the infrared detector 11, servo motor 15, and bidirectional screw 16, when the transparent paper is used to the end and no longer covers the top of the infrared detector 11, the servo motor 15 receives a signal and drives the bidirectional screw 16 to rotate. This causes the upper splicing plate 2 and the lower splicing plate 4 to move closer to each other and splice the new transparent paper head segment that is restricted by the limiting component 14 with the original transparent paper end segment. The whole operation does not require manual intervention, reducing the labor intensity of manual labor.

[0029] The upper splicing plate 2 has a rectangular groove 201 on the side of the infrared detector 11 near the lower splicing plate 4. The upper splicing plate 2 has a limiting groove 202 on the side away from the rectangular groove 201. The limiting groove 202 is movably connected to the limiting component 14. The upper splicing plate 2 and the lower splicing plate 4 are both provided with lifting sliders 13 on the surface of the side of the upper splicing plate 2 and the lower splicing plate 4 near the main support plate 1. The lifting sliders 13 facilitate the lifting and lowering of the upper splicing plate 2 and the lower splicing plate 4.

[0030] The limiting component 14 includes a rectangular extrusion plate 1401. A regularly arranged telescopic column 1402 is fixedly connected to one side of the rectangular extrusion plate 1401. A spring 1403 is movably connected to one end of the telescopic column 1402 inside the upper splicing plate 2. The limiting component 14 helps to fix and limit the beginning of the transparent paper to be spliced.

[0031] The auxiliary support plate 3 has a second mounting groove 302 located at the position where the pre-material shaft 6 and the main material shaft 7 are movably connected. The auxiliary support plate 3 has a second sliding groove 301 located at the position where the upper splicing plate 2 and the lower splicing plate 4 are movably connected. The auxiliary support plate 3 has a rectangular observation window 303 located at the middle position adjacent to the second sliding groove 301. The auxiliary support plate 3 helps to restrict the upper splicing plate 2 and the lower splicing plate 4.

[0032] The main support plate 1 has a first mounting groove 104 located at the position where the pre-material shaft 6 and the main material shaft 7 are movably connected. The main support plate 1 has a first sliding groove 101 located at the position where the upper splicing plate 2 and the lower splicing plate 4 are movably connected. The main support plate 1 has a lifting sliding groove 102 located at the middle position adjacent to the first sliding groove 101. A bidirectional screw 16 is movably sleeved inside the lifting sliding groove 102. A servo motor 15 is fixedly connected to the top position of the main support plate 1. The servo motor 15 is connected to the top position of the bidirectional screw 16. Through the servo motor 15 and the bidirectional screw 16, it is beneficial to drive the upper splicing plate 2 and the lower splicing plate 4 to move.

[0033] Among them, the installation limit block 8 has a regularly arranged limit support rod 801 on one side surface near the pre-material shaft 6 and the main material shaft 7.

[0034] The working principle of this utility model:

[0035] First, when the transparent paper at position 7 of the main material shaft is used to the end, the end of the transparent paper is driven by the limiting roller 5 to gradually move away from the infrared detector 11 at the top of the lower splicing plate 4. At this time, the top of the infrared detector 11 is not covered by transparent paper and triggers the sensor. At this time, the servo motor 15 is started, and then the servo motor 15 drives the bidirectional screw 16 to rotate. At this time, the bidirectional screw 16 rotates and drives the lifting slider 13 to move. At this time, the lifting slider 13 drives the upper splicing plate 2 and the lower splicing plate 4 to move closer to each other under the restriction of the rectangular slider 10. At this time, the splicing soldering iron 9 opened on the adjacent surfaces of the upper splicing plate 2 and the lower splicing plate 4 are energized and the limiting component 14 is restricted to the limiting groove 202 position. The beginning of the new transparent paper is driven. At this time, the beginning of the transparent paper at the position of the limiting component 14 and the end of the transparent paper at the position of the servo motor 15 move closer to each other and are spliced ​​at the position of the splicing soldering iron 9. Then, after the splicing soldering iron 9 splices the transparent paper, it is reset by the servo motor 15.

[0036] Then, the servo motor 15 drives the spliced ​​transparent paper to move. At this time, the servo motor 15 pulls the transparent paper, which is restricted by the position limit component 14, and pulls it away from the position limit component 14. Then, the mounting limit blocks 8 on both sides of the main material shaft 7 are pulled to both sides, so that the main material shaft 7 is separated from the first slide groove 101 and the second slide groove 301 opened in the main support plate 1 and the auxiliary support plate 3. Then, the mounting limit blocks 8 on both sides of the pre-material shaft 6 are pulled away, so that the pre-material shaft 6 moves to the position of the main material shaft 7. Then, the new transparent paper roll is placed and installed in the original position of the pre-material shaft 6. Then, the head end of the new transparent paper is pulled to the bottom position of the upper splicing plate 2, so that the head end of the new transparent paper enters the position of the limit groove 202. Then, the rectangular extrusion plate 1401 pushes the telescopic column 1402 to compress the spring 1403. Then, the spring 1403 pushes back, so that the rectangular extrusion plate 1401 restricts the head end of the new transparent paper to prepare for the next splicing.
