Description

Technical Field

[0001] The utility model relates to cigarette packing equipment, in particular to a cigarette packing machine capable of removing excess packing film. Background Art

[0002] In the process of tobacco product distribution, the packaging production line needs to sort and package the cigarettes according to the type and quantity of each order. Figure 1-3 As shown, the existing packaging production line includes a first conveyor belt, a cigarette wrapping machine, a second conveyor belt, a side film sealing system and a third conveyor belt connected in sequence. The cigarette wrapping machine includes a first frame, a film placing device is provided on the side of the first frame facing the first conveyor belt, a first cigarette conveyor belt is provided on the first frame, a rear end film sealing and cutting machine is provided on the side of the first cigarette conveyor belt close to the first conveyor belt, the side film sealing system includes a second frame, a second cigarette conveyor belt is provided on the second frame, a cigarette rear end sensor and two side film sealing machines are provided on the second cigarette conveyor belt, the cigarette rear end sensor is arranged between the two side film sealing machines and the second conveyor belt, and the two side film sealing machines are fixedly arranged on the second frames on both sides of the second cigarette conveyor belt. After sorting, the cigarettes from each order are longitudinally fed into the first conveyor belt and transported to the cigarette wrapping machine. The leading edge of the cigarettes from one order initially presses against the wrapping film, which then unfolds as the cigarettes from that order continue to move. When the wrapping machine detects the trailing edge of the cigarettes from that order, it thermoplastically seals and cuts the wrapping film to form cigarette packs. The packs then enter the second conveyor belt and are transported to the side-sealing system, where the wrapping film on both sides of the packs is thermoplastically sealed. After sealing, they enter the third conveyor belt and are transported to the next process. These packs may contain one, two, three, or four cigarettes, but the wrapping film width is fixed. When there are four cigarettes in a pack, the wrapping film on both sides is just right. However, when there are only one, two, or three cigarettes in a pack, there is excess wrapping film on both sides, which takes up transportation space and increases transportation costs.

The two ends of the first cigarette conveyor belt 9 are respectively connected to the first conveyor belt 1 and the second conveyor belt 3. A rear end film sealing and cutting machine 10 is provided on the side of the first cigarette conveyor belt 9 close to the film placing device 7. The rear end film sealing and cutting machine 10 performs thermoplastic packaging and cutting on the packaging film 8 at the rear end of the cigarette. The above embodiments are all prior art. The first cigarette conveyor belt A side film cutting system is provided on the side of the belt 9 near the second conveyor belt 3. This system includes a first cigarette side position sensor 11, two sets of first linear motion mechanisms 12, two side film cutters 13, two pads 14, and a first controller. The first cigarette side position sensor 11 is located on the first frame 6 between the rear film sealing and cutting machine 10 and the two side film cutters 13. The first cigarette side position sensor 11 is an infrared ranging sensor used to detect its distance from the cigarette 15 (the cigarette 15 conveyed by the first conveyor belt 1 is located in the middle of the first conveyor belt 1 in the width direction). The two sets of first linear motion mechanisms 12 are respectively connected to the first frames 6 on both sides of the first cigarette conveyor belt 9.

Figure 7As shown, the side sealing system 4 includes a second frame 19, and a second cigarette conveyor belt 20 is provided on the second frame 19. The two ends of the second cigarette conveyor belt 20 are respectively connected to the second conveyor belt 3 and the third conveyor belt 5. The second cigarette conveyor belt 20 is provided with a second cigarette side position sensor 21, two sets of second linear motion mechanisms 22, two side sealing machines 23 and a second controller. The second cigarette side position sensor 21 is arranged on the second frame 19 between the two side sealing machines 23 and the second conveyor belt 3. The second cigarette side position sensor 21 is an infrared ranging sensor, which is used to detect the distance between it and the cigarette 15 (the cigarette conveyed by the first conveyor belt 1 is located in the middle in the width direction of the first conveyor belt 1). The two groups of second linear motion mechanisms 22 are respectively connected to the second frames 19 on both sides of the second cigarette conveyor belt 20. The two groups of second linear motion mechanisms 22 are arranged along the width direction of the second cigarette conveyor belt 20. Each group of second linear motion mechanisms 22 has a second linear motion mechanism 22. The second linear motion mechanism 22 is an electric telescopic rod. The ends of the two groups of second linear motion mechanisms 22 are respectively connected to the middle parts of the two second mounting blocks 24. The lower sides of the two second mounting blocks 24 are respectively connected to the two side sealing machines 23. The two second mounting blocks 24 are both long strips. The two second mounting blocks 24 are parallel to the conveying direction of the second cigarette conveyor belt 20. Through holes are respectively provided at both ends of each second mounting block 24. Two second guide rods 25 are connected between the second frames 19 on both sides of the second cigarette conveyor belt 20. The two through holes of each second mounting block 24 are respectively sleeved on the two second guide rods 25. The side film sealing machine 23 includes a second lifting mechanism and a hot melt assembly 26. The upper end of the second lifting mechanism is connected to the second mounting block 24, and the lower end is connected to the hot melt assembly 26.

[0029] When the cigarette packing machine is in use, the cigarettes 15 of each order after sorting enter the first conveyor belt 1 from the middle of the width direction of the first conveyor belt 3 in a longitudinal manner (that is, the long side of the cigarettes is parallel to the conveying direction of the first conveyor belt 1), and are transported to the cigarette wrapping machine 2 by the first conveyor belt 1. On the cigarette wrapping machine 2, the front end of the cigarettes 15 of an order first presses against the packaging film 8, and the packaging film 8 is driven to unfold as the cigarettes 15 of the order continue to move. When the side position sensor 11 of the first cigarette detects the distance between it and the cigarette 15 (the distance is within the set range, if it is detected outside the set range, it is not a cigarette 15), the controller controls the two groups of first linear motion mechanisms 12 to move and thereby drive the two side film cutting machines 13 towards The cigarette strips 15 move until they are close to the side of the cigarette strips 15 of the order. As the cigarette strips 15 of the order continue to move, the packaging films 8 on both sides of the cigarette strips of the order slowly enter between the cutters 18 and the pads 14 on both sides of the first cigarette conveyor belt 9. When the rear-end film sealing and cutting machine 10 detects the rear end of the cigarette strips 15 of the order, the first cigarette conveyor belt 9 stops, and the packaging film 8 on the rear end of the cigarette strips 15 of the order is thermoplastically sealed and cut. The first cigarette conveyor belt 9 then continues to run for a certain distance and then stops. The controller then controls the two first lifting mechanisms to descend, and the blades 18 at the lower ends of the two first lifting mechanisms cut the excess packaging film 8 on both sides of the cigarette strips 15 of the order on the two pads 14, thereby forming a cigarette pack 27. Afterwards, the controller controls the first cigarette conveyor belt 9 to continue running so that the cigarette pack 27 enters the second conveyor belt 3, and is sent to the side sealing system 4 by the second conveyor belt 3. When the second cigarette side position sensor 21 on the side sealing system 4 detects the distance between it and the cigarette 15 in the cigarette pack 27 (the distance is within the set range, if it is outside the set range, it is not a cigarette 15), the controller controls the two sets of second linear motion mechanisms 22 to move and then drives the two side sealing machines 23 to move respectively until they move to the side of the cigarette 15 close to the cigarette pack 27. When the distance detected by the second cigarette side position sensor 21 is outside the set range, the controller controls the second cigarette conveyor belt 20 to stop, the controller controls the two second lifting mechanisms to descend, and controls the power switch of the hot melt component 26 to turn on. The two sets of hot melt components 26 respectively perform thermoplastic sealing on the packaging film 8 on both sides of the cigarette pack 27. At this point, the packaging of the cigarette 15 is completed, and the second cigarette conveyor belt 20 is started to transport the packaged cigarette pack to the third conveyor belt 5, which is then transported to the next process by the third conveyor belt 5.

[0030] The two side film cutters 13 on the cigarette wrapping machine 2 of the baler can cut off the excess packaging film 8 on both sides of the cigarette strips 15 of each order, and the two side film sealers 23 on the side film sealing system 4 can seal the packaging film 8 on both sides of each cigarette pack 27, so that there is no excess packaging film 8 in the final cigarette pack 27, solving the technical problem that the excess packaging film 8 of the cigarette pack 27 will occupy the transportation space. The setting of the pad 14 prevents the cutter 18 from damaging the first cigarette conveyor belt 9. The purpose of the setting of the first mounting block 16 and the first guide rod 17 is to support and guide the side film cutter 13. The purpose of the setting of the second mounting block 24 and the second guide rod 25 is to support and guide the side film sealer 13.

[0031] Example 2

[0032] like Figure 4-6 As shown, the difference from the first embodiment is that a waste film collection port 28 is provided on the first frame 6 on both sides of the first cigarette conveyor belt 9, the waste film collection port 28 is connected to a waste film collection tank 29, and the waste film collection tank 29 is connected to a vacuum pump.

[0033] The vacuum pump generates negative pressure in the waste film collecting tank 29 , and the waste film on the first cigarette conveyor belt 9 is sucked into the waste film collecting tank 29 through the waste film collecting port 28 under the negative pressure adsorption.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
