Description

Technical Field

[0001] The utility model relates to a stiffness maintaining device for tipping paper after reverse winding, belonging to the technical field of tipping paper equipment. Background Art

[0002] Tipping paper is a packaging material widely used in consumer goods such as cigarettes and filter tips. During the production process, tipping paper needs to go through processes such as reverse winding and cutting. However, during the reverse winding process, the tipping paper is prone to losing stiffness due to the action of gravity and friction, affecting the quality of the tipping paper. After retrieval, it is found that the Chinese patent with the publication number CN219807559U discloses a tipping paper rewinder for cigarettes. In this patent, the tipping paper for cigarettes is placed on a reel, and one end of the paper is fixed to a rotating shaft. The winding device is started, the rotating shaft drives the turntable to rotate, and through the cooperation of pulleys, sliding columns and chutes, the tipping paper is evenly wound on the reel. The tension of the tipping paper is adjusted through the torsion spring at the connection between the rotating shaft and the sleeve, as well as the rotating arm and the pressing rod on the side wall of the support plate. The tipping paper is guided by guide wheels and guide columns, and the slider and the support rod ensure the smoothness of the paper during winding. When the tipping paper is wound to the set length, the blade at the bottom of the slider cuts, dividing the paper into the required length. After cutting, the take-up roller starts to work, moving the wound tipping paper from the reel to the take-up groove, completing the entire winding and take-up process. However, in this patent, the tipping paper is only tensioned and then cut and taken up. If there are problems such as excessive humidity and low stiffness of the tipping paper on the reel and it is cut without treatment, it will have a negative impact on the subsequent use and quality inspection of the tipping paper, affecting the qualification rate of the final product.

[0030] AsFigures 1-5 As shown in the figure, a stiffness maintaining device for tipping paper after reverse winding includes:

[0031] A frame 1;

[0032] A unwinding roller 2, which is installed on the frame 1;

[0033] A winding mechanism, which includes a winding support 31 and a winding roller 32. The winding support 31 is connected to the frame 1, and the winding roller 32 is installed on the winding support 31;

[0034] A drying device 4, which is installed on the frame 1. The drying device 4 is provided with a conveying channel 41, and the drying device 4 is suitable for drying the tipping paper entering the conveying channel 41.

[0035] In this embodiment, the drying device 4 is provided with a blower and a heater. The blower is used to send air into the heater, and the heater heats the air sent by the blower. The heated air blows towards the conveying channel 41. The tipping paper to be processed is placed through the unwinding roller 2, and the tipping paper entering the conveying channel 41 is dried through the drying device 4.

[0036] There is a certain relationship between the stiffness and humidity of the tipping paper. When the tipping paper is in a low-humidity environment, the moisture in the tipping paper will gradually evaporate, the binding force between fibers will increase, and the stiffness of the tipping paper will also increase relatively.

[0037] Specifically, as Figures 1-2 shown, the stiffness maintaining device for tipping paper after reverse winding further includes a flattening mechanism. The flattening mechanism is arranged at the outlet of the conveying channel 41. The flattening mechanism includes a flattening support 51, a first driving roller 52 and a second driving roller 53. The flattening support 51 is installed on the frame 1, and the first driving roller 52 and the second driving roller 53 are both rotatably installed on the flattening support 51.

[0038] Specifically, as Figure 5 shown, the flattening mechanism further includes a flattening device 54. The flattening device 54 is installed on the flattening support 51. The flattening device 54 is provided with a flattening groove 541, and a flattening plate 542 is arranged in the flattening groove 541.

[0039] Specifically, as Figure 5 shown, the flattening plate 542 is installed in the flattening groove 541 through at least one screw-nut pair; among them,

[0040] The screw-nut pair includes:

[0041] A screw 543 installed on the flattening device 54;

[0042] A nut 544 installed on the flattening plate 542.

[0043] In this embodiment, according to the actual thickness of the tipping paper, the lead screw 543 is rotated to drive the flattening plate 542 to adjust its position to ensure that the flattening plate 542 can effectively flatten the tipping paper after drying.

[0044] Specifically, as Figures 1-2 shown, a stiffness maintaining device for rewound tipping paper further includes a first guiding roller 6. The first guiding roller 6 is rotatably installed on the frame 1. The first guiding roller 6 is disposed between the unwinding roller 2 and the drying device 4.

[0049] Specifically, as Figure 1 shown, the tensioning roller 83 is further provided with an adjusting device. The adjusting device includes an adjusting plate 81, a fastening screw 82 and the tensioning roller 83. The adjusting plate 81 is provided with a waist-shaped hole 811.

[0050] In this embodiment, the tipping paper is released from the unwinding roller 2 and guided into the conveying channel 41 of the drying device 4 through the first guiding roller 6.
