[0002] The main function of the transparent paper outer packaging of cigarettes is to protect the products. Usually, a pulling wire is pasted on the transparent paper. The transparent paper with the pulling wire passes through a roller and a pulling wire cutter. The driving motor rotates to drive the pulling wire cutter to cut the pulling wire. After the cigarette carton packaging is completed, when the consumer uses it, the cigarette product can be used by tearing it from the cutting opening of the pulling wire. At present, the pulling wire often falls off the pulling wire roller during the conveying process, resulting in the dislocation of the pulling wire of the cigarette pack. To avoid this situation, a device for preventing the falling off of the pulling wire is needed.
[0003] The existing device for preventing the falling off of the pulling wire lacks a displacement function. When the transparent paper is slightly offset, the position of the pulling wire on the transparent paper will be offset, resulting in the dislocation of the pulling wire of the cigarette pack.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a device for preventing the falling off of the pulling wire of a degassing packaging machine is proposed. Content of the Utility Model

[0021] The following further describes the implementation manner of the present utility model in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.
[0022] As Figures 1 to 3 shown, a wire anti - shedding device for a degassing packaging machine includes a slide plate 1 and a wire supply roller 8. A support 2 is slidably arranged on the slide plate 1, and a rack 3 is fixed in the middle of the lower part of the rear end of the support 2. There are two slide plates 1 symmetrically arranged about the vertical central axis of the support 2, and the slide plates 1 and the rack 3 are parallel to each other. A gear 4 is connected above the rack 3, and a first drive shaft 5 passes through the middle of the gear 4. The right end of the first drive shaft 5 is connected to a forward and reverse motor one 6, and a support plate 7 is arranged on the left side of the forward and reverse motor one 6. The wire supply roller 8 is rotatably arranged in the middle of the surface of the support 2, and a first guide roller 9 is rotatably arranged on the right side of the surface of the support 2. An auxiliary component 10 is arranged on the surface of the support 2, and the auxiliary component 10 includes a fixed disc 1001, a pawl 1002, a spring 1003, a ratchet 1004, a swing arm 1005 and a second guide roller 1006. The pawl 1002 is rotatably connected to the groove on the outside of the fixed disc 1001, and a spring 1003 is connected to one side of the pawl 1002. The ratchet 1004 is arranged outside the fixed disc 1001, and a swing arm 1005 is fixed on the front surface of the ratchet 1004. A second guide roller 1006 is rotatably arranged on the right side of the surface of the swing arm 1005. The pawl 1002 is elastically connected to the fixed disc 1001 through the spring 1003, and the thickness of the pawl 1002 is greater than the thickness of the fixed disc 1001. The fixed disc 1001 and the ratchet 1004 have the same thickness, and the fixed disc 1001 and the swing arm 1005 are rotatably connected.
[0023] The specific operation is as follows. The pawl 1002 relies on the elastic support of the spring 1003 to engage with the teeth inside the ratchet 1004, thereby preventing the ratchet 1004 and the swing arm 1005 from rotating counterclockwise, forming a locked state, restricting the wire between the first guide roller 9 and the second guide roller 1006, and preventing the wire from jumping out of the first guide roller 9.
[0024] As Figure 1As shown in the figure, a forward and reverse motor II 11 is installed above the left side of the rear end of the support 2, and the output end of the forward and reverse motor II 11 penetrates through the support 2 and is connected with a drive shaft II 12. An active gear 13 is sleeved outside the drive shaft II 12, and a driven gear 14 is connected outside the active gear 13. A transmission shaft 15 passes through the middle of the driven gear 14, and swing rods 16 are connected to the outside of both the drive shaft II 12 and the transmission shaft 15. A pressure roller 17 is rotatably arranged at the right end of the swing rod 16, and two swing rods 16 and two pressure rollers 17 are provided respectively.
[0025] The specific operation is as follows: The forward and reverse motor II 11 drives the drive shaft II 12 and the active gear 13 to rotate. The active gear 13 drives the driven gear 14 to drive the transmission shaft 15 to rotate. The pressure rollers 17 on the two swing rods 16 with opposite rotation directions respectively press the top and bottom ends of the wire supply roller 8, ensuring the cross-section fastening force of the wire on the wire supply roller 8 and preventing it from loosening.
[0026] In summary, for the wire anti-dropping device of the degassing packaging machine, during use, first pull the wire outside the wire supply roller 8 to the groove on the outside of the guide roller I 9, and then rotate the swing arm 1005 to limit the wire between the guide roller I 9 and the guide roller II 1006. Since the pawl 1002 relies on the elastic support of the spring 1003 to keep meshing with the teeth inside the ratchet wheel 1004, the ratchet wheel 1004 and the swing arm 1005 are prevented from rotating counterclockwise, thus locking the position of the guide roller II 1006 and preventing the wire from jumping out of the guide roller I 9 and causing dropping.
[0027] During the working process, when the transparent paper is slightly offset, by operating the forward and reverse motor I 6, the forward and reverse motor I 6 drives the drive shaft I 5 and the gear 4 to rotate. The gear 4 drives the rack 3 to drive the support 2 to slide linearly in the front and back directions on the slide plate 1, ensuring that the wire outside the wire supply roller 8 is aligned with the transparent paper and avoiding wire misalignment of the cigarette package.
[0028] When the work is finished, control the forward and reverse motor II 11 to drive the drive shaft II 12 and the active gear 13 to rotate. The active gear 13 drives the driven gear 14 to drive the transmission shaft 15 to rotate. The pressure rollers 17 on the two swing rods 16 with opposite rotation directions respectively press the top and bottom ends of the wire supply roller 8, ensuring the cross-section fastening force of the wire on the wire supply roller 8 and preventing it from loosening.
[0029] Since the thickness of the pawl 1002 is greater than the thickness of the fixed disc 1001 and the ratchet wheel 1004, the pawl 1002 is extruded from the gap between the fixed disc 1001 and the ratchet wheel 1004 to deform the spring 1003, enabling the ratchet wheel 1004 and the swing arm 1005 to have the ability to rotate clockwise, facilitating the limitation of the wire on the replaced wire supply roller 8 and playing a role in preventing the wire from running off.
[0030] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present utility model and its practical applications, and to enable those of ordinary skill in the art to understand the present utility model so as to design various embodiments with various modifications suitable for specific purposes.
