Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette production, and in particular relates to a flattening roller device of a sealing machine. Background Art

[0002] As we all know, the wider the paper is, the more likely it is to have edge wrinkles, curling or adhesion during the winding process, which will make the winding not neat and affect the quality of the rolled paper. At present, the existing sealing paper is usually continuously rolled by a pressure roller during the winding process to prevent it from wrinkling or curling. However, since the position of the pressure roller remains fixed, the pressure of the pressure roller on the passing sealing paper is also kept constant. Therefore, it is impossible to increase the pressure on the sealing paper according to the actual situation of the sealing paper. If the sealing paper is soft or the wrinkles are more serious, it cannot be completely flattened when passing through the pressure roller. After the sealing paper is wound around the winding roller, the rolled sealing paper will still have different radial tightness and unevenness, which greatly affects the winding effect of the sealing paper and the quality of subsequent processing.

[0024] Please continue to participate Figure 2 and Figure 3In order to reduce the friction force when the sealing paper passes through the first transmission roller 2 and the second transmission roller 3, the first transmission roller 2 includes a first rotating shaft 21 and a first roller body 22 rotatably connected to the outside of the first rotating shaft 21. A plurality of first bearings 211 are provided outside the first rotating shaft 21, and the inner surface of the first roller body 22 is in contact with the outer surfaces of the plurality of first bearings 211. When the sealing paper passes through the first transmission roller 2, the first roller body 22 will also rotate at the same time.

In this embodiment, the number of the first bearings 211 is two, and the first bearings 211 are respectively provided at the two ends of the first roller body 22. In order to prevent the first roller body 22 from moving during the rotation process, a first limiting portion 212 for limiting the first roller body 22 and the first bearing 211 is provided on the first rotating shaft 21. The first limiting portion 212 is provided outside the two ends of the first roller body 22. Specifically, the first limiting portion 212 is two limiting rings, and the two limiting rings are fixed to the first rotating shaft 21 by bolts. By setting the first limiting portion 212, the first roller body 22 can be limited so that it can only rotate between the first limiting portions 212. Similarly, the second transmission roller 3 includes a second rotating shaft 31 and a second roller body 32 rotatably connected to the outside of the second rotating shaft 31. A plurality of second bearings 311 are provided outside the second rotating shaft 31, and the inner surface of the second roller body 32 is attached to the outer surfaces of the plurality of second bearings 311. When the sealing paper passes through the second transmission roller 3, the second roller body 32 will also rotate at the same time.

The second limiting parts 312 are also two limiting rings, which are fixed to the second rotating shaft 31 by bolts. The second limiting parts 312 can be provided to limit the second roller body 32 so that it can only rotate between the second limiting parts 312 .

[0025] Please continue to participate Figure 4 and Figure 5In order to adjust the pressure roller 4, in this embodiment, the lifting assembly 5 includes a driving device 51, a transmission member 52, a first threaded rod 53, a second threaded rod 54 and a threaded sleeve 55. The driving device 51 is arranged on the connecting seat 11. In this embodiment, the driving device 51 is a driving motor. The first threaded rod 53 and the second threaded rod 54 are respectively connected to the first mounting seat 121 and the second mounting seat 131 in longitudinal rotation. The output end of the driving device 51 is connected to the transmission member 52 in transmission connection, and the ends of the first threaded rod 53 and the second threaded rod 54 away from the first mounting seat 121 and the second mounting seat 131 are connected to the transmission member 52 in transmission connection. The threaded sleeve 55 is fixedly connected to the two ends of the pressure roller 4, and the two ends of the pressure roller 4 are respectively threadedly connected to the outer sides of the first threaded rod 53 and the second threaded rod 54 through the threaded sleeve 55. When in use, the transmission member 52 is first rotated by the driving device 51, and then the first threaded rod 53 and the second threaded rod 54 are driven to rotate by the transmission member 52. Since threaded sleeves 55 are provided at both ends of the pressure roller 4, when the first threaded rod 53 and the second threaded rod 54 rotate, the threaded sleeves 55 can move along the height direction of the first threaded rod 53 and the second threaded rod 54. Since the threaded sleeves 55 are fixedly connected to the two ends of the pressure roller 4, the height of the pressure roller 4 can be adjusted.

[0026] In this embodiment, the transmission member 52 specifically includes a transmission shaft 521, a first driving gear 522, a second driving gear 523, a first driven gear 524, and a second driven gear 525. The transmission shaft 521 is transmission-connected to the output end of the driving device 51, the first driving gear 522 and the second driving gear 523 are respectively fixed to the two ends of the transmission shaft 521, the first driven gear 524 is arranged at one end of the first threaded rod 53 close to the transmission shaft 521, and the first threaded rod 53 is transmission-connected to the transmission shaft 521 through the first driven gear 524 and the first driving gear 522, the second driven gear 525 is arranged at one end of the second threaded rod 54 close to the transmission shaft 521, and the second threaded rod 54 is transmission-connected to the transmission shaft 521 through the second driven gear 525 and the second driving gear 523. When the driving device 51 is running, the transmission shaft 512 is driven to rotate, and the first driving gear 522 and the second driving gear 523 at both ends of the transmission shaft 521 rotate accordingly, thereby driving the first driven gear 524 and the second driven gear 525 meshing with the first driving gear 522 and the second driving gear 523 to rotate. Since the first driven gear 524 and the second driven gear 525 are fixedly connected to the first threaded rod 53 and the second threaded rod 54 respectively, the first threaded rod 53 and the second threaded rod 54 can be rotated.

[0027] In order to make the first threaded rod 53 and the second threaded rod 54 rotate in the same direction, the first driving gear 522 and the second driving gear 523 are respectively located on the same side of the first driven gear 524 and the second driven gear 525. This design can make the first threaded rod 53 and the second threaded rod 54 rotate in the same direction, so that the threaded sleeve 55 moves in the same direction. If the first driving gear 522 and the second driving gear 523 are located on different sides of the first driven gear 524 and the second driven gear 525, the first threaded rod 53 and the second threaded rod 54 will rotate in opposite directions, so that the threaded sleeve 55 will move in opposite directions, and the pressure roller 4 cannot move. In order to protect the connection, a protective cover 6 is provided at the connection between the first driving gear 522 and the first driven gear 524 and the connection between the second driving gear 523 and the second driven gear 525. The protective cover 6 can prevent dust and other impurities from entering the connection between the first driving gear 522 and the first driven gear 524 and the connection between the second driving gear 523 and the second driven gear 525, causing the first driving gear 522 and the first driven gear 524 and the second driving gear 523 and the second driven gear 525 to get stuck, thereby shortening their service life.

[0028] In order to facilitate the use of the operator, a control box 7 is arranged on the front side of the first side frame 12, and the control box 7 is electrically connected to the driving device 51. At the same time, a wireless receiver is arranged in the control box 7, and the wireless receiver is wirelessly connected to the wireless remote controller, and the wireless receiver can be used in conjunction with the wireless remote controller. The operator can control the start and stop of the driving device 51 through the control box 7, and can also control the start and stop of the driving device 51 through the remote controller at a distance during the winding process. A variety of control methods can be selected for the operator, which is more convenient to operate. The remote control method allows the operator to be farther away from the running equipment and is safer.

[0029] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the utility model.
