Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, and in particular to a paper sheet wrinkling removal device after sizing. Background Technology

[0002] In the existing equipment process, after the paper is sized by the sizing machine, guide rollers are usually used as guiding devices to lead the sized semi-wet paper sheet to the drying section for drying. The guide rollers can guide the paper to move in the required direction, so that the paper can be smoothly and accurately transferred to the next process after sizing.

[0003] The main function of existing guide rollers is to guide the paper sheet from the sizing section to the drying section. However, after sizing, the paper sheet is prone to wrinkles due to changes in moisture content and wear or improper adjustment of the sizing equipment. Guide rollers cannot smooth out the paper sheet and cannot remove wrinkles. When the wrinkled paper sheet enters the drying section of the paper machine, uneven heating and drying during the drying process may cause further unevenness, which will affect the appearance quality of the paper. At the same time, the paper fibers in the wrinkled areas will be damaged due to excessive stretching or compression, resulting in a decrease in paper strength. This makes the finished paper more prone to tearing or breakage during subsequent processing or use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing paper sizing machines where the guide rollers cannot smooth out wrinkled paper, and to provide a paper wrinkle removal device after sizing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a paper sheet wrinkling removal device after sizing in papermaking, comprising: a wrinkling removal mechanism, the wrinkling removal mechanism including an arc-shaped mandrel, a roller sleeve sleeved on the outer side of the arc-shaped mandrel, a bearing first sleeved on the outer surface of the arc-shaped mandrel, the bearing first being placed inside the roller sleeve, the bearing first being fixedly connected to both the outer surface of the arc-shaped mandrel and the inner wall of the roller sleeve, a rubber sleeve sleeved on the outer surface of the roller sleeve, the rubber sleeve being fixedly connected to the roller sleeve, the rubber sleeve having a spiral groove, an oil seal sleeved on the outer surface of the arc-shaped mandrel, the oil seal being sleeved inside the roller sleeve, the oil seal being fixedly connected to both the arc-shaped mandrel and the roller sleeve, a dust cover sleeved on the outer surface of the arc-shaped mandrel, the dust cover being fixedly connected to the arc-shaped mandrel, an adjusting handwheel sleeved on the outer surface of one end of the arc-shaped mandrel, an end cap sleeved on the outer surface of one end of the arc-shaped mandrel, and a driving mechanism provided on one side of the arc-shaped mandrel, the driving mechanism including a rotating rod.

[0006] In a preferred embodiment, the end cap has a mounting groove that matches the arc-shaped mandrel, and the adjusting handwheel and the bottom of the end cap are fixedly connected to a support.

[0007] In a preferred embodiment, the rotating rod is sleeved inside one of the supports, the rotating rod is rotatably connected to the support, and one end of the rotating rod is provided with a hand rope wheel, which is fixedly connected to the rotating rod.

[0008] In a preferred embodiment, a pulley is fitted onto the outer surface of one end of the rotating rod, the pulley is fixedly connected to the rotating rod, and a timing belt is fitted onto the outer surface of the pulley.

[0009] In a preferred embodiment, the pulley is engaged with a timing belt, and the timing belt is sleeved on the outer surface of a rubber sleeve.

[0010] In a preferred embodiment, the pulley is connected to the rubber sleeve via a synchronous belt, and a bearing is sleeved on the outer surface of the rotating rod.

[0011] In a preferred embodiment, the second bearing is placed in a groove on one of the supports, and the second bearing is fixedly connected to the inner wall of the support and the outer surface of the rotating rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, by incorporating a wrinkle-removing mechanism, removes wrinkles from paper passing through the rubber sleeve, thereby improving paper production quality. Furthermore, the arc-shaped mandrel, roller sleeve, and rubber sleeve are all arc-shaped, allowing them to work together to stretch the paper laterally as it passes through the rubber sleeve. The rubber sleeve also features spiral grooves; these spiral patterns exert a specific tensile force on the paper as it passes over the roller surface. Because the patterns are spirally distributed, they apply force simultaneously along the transverse and longitudinal directions, resulting in uniform stretching of the paper in multiple directions. This stretching helps eliminate wrinkles in the paper. Additionally, a drive mechanism is included, which works in conjunction with the wrinkle-removing mechanism, allowing the rubber sleeve to rotate at a certain speed, cooperating with the paper during transport to perform wrinkle removal.

Example

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a paper sheet wrinkling device after sizing in papermaking, comprising: a wrinkling mechanism 1, the wrinkling mechanism 1 including an arc-shaped mandrel 11, a roller sleeve 12 sleeved on the outer side of the arc-shaped mandrel 11, a bearing 13 sleeved on the outer surface of the arc-shaped mandrel 11, the bearing 13 being placed inside the roller sleeve 12, the bearing 13 being fixedly connected to both the outer surface of the arc-shaped mandrel 11 and the inner wall of the roller sleeve 12, a rubber sleeve 14 sleeved on the outer surface of the roller sleeve 12, the rubber sleeve 14 being fixedly connected to the roller sleeve 12, the rubber sleeve 14 having a spiral groove 15, the outer surface of the arc-shaped mandrel 11 being sleeved with... There is an oil seal 16, which is sleeved inside the roller sleeve 12. The oil seal 16 is fixedly connected to both the arc-shaped mandrel 11 and the roller sleeve 12. A dust cover 17 is sleeved on the outer surface of the arc-shaped mandrel 11 and is fixedly connected to the arc-shaped mandrel 11. An adjusting handwheel 18 is sleeved on the outer surface of one end of the arc-shaped mandrel 11, and an end cover 19 is sleeved on the outer surface of the other end of the arc-shaped mandrel 11. A drive mechanism 2 is provided on one side of the arc-shaped mandrel 11. The drive mechanism 2 includes a rotating rod 21. An installation groove that fits the arc-shaped mandrel 11 is opened on the end cover 19. A support 101 is fixedly connected to the bottom of the adjusting handwheel 18 and the end cover 19.

[0024] In this embodiment, by setting an arc-shaped mandrel 11 and a roller sleeve 12, both of which are arc-shaped, the rubber sleeve 14 fitted onto the outer surface of the roller sleeve 12 can maintain its arc shape, thereby enabling the transfer and wrinkle removal of the paper during transport.

Bearings 13 are provided and positioned between the arc-shaped mandrel 11 and the roller sleeve 12. Multiple bearings 13 are provided, allowing their inner and outer rings to cooperate with the arc-shaped mandrel 11 and the roller sleeve 12. This allows the roller sleeve 12 to rotate under the cooperation of the bearings 13, thus enabling the rubber sleeve 14, which is fixedly connected to the roller sleeve 12, to rotate. A spiral groove 15 is provided on the sleeve 14, allowing the rubber sleeve 14 to apply force to the paper in both the transverse and longitudinal directions simultaneously, so that the paper is stretched evenly in multiple directions. An adjustment handwheel 18 is provided, and the adjustment handwheel 18 is an existing object with complete functions. The curved mandrel 11 and the adjustment handwheel 18 are securely connected through the tightening component provided on the adjustment handwheel 18.

Example

[0025] like Figures 1-5 As shown, a rotating rod 21 is sleeved inside one of the supports 101, and the rotating rod 21 is rotatably connected to the support 101. One end of the rotating rod 21 is provided with a hand rope wheel 22, which is fixedly connected to the rotating rod 21. A pulley 23 is sleeved on the outer surface of one end of the rotating rod 21, and the pulley 23 is fixedly connected to the rotating rod 21. A synchronous belt 24 is sleeved on the outer surface of the pulley 23, and the pulley 23 and the synchronous belt 24 are meshed and connected for transmission. The synchronous belt 24 is sleeved on the outer surface of the rubber sleeve 14, and the pulley 23 is connected to the rubber sleeve 14 for transmission through the synchronous belt 24. A bearing 25 is sleeved on the outer surface of the rotating rod 21, and the bearing 25 is placed in a groove opened on one of the supports 101. The bearing 25 is fixedly connected to the inner wall of the support 101 and the outer surface of the rotating rod 21.

[0026] In this embodiment, by setting a drive mechanism 2, the rubber sleeve 14 can rotate at a suitable speed. A hand rope wheel 22 is set, and when the hand rope wheel 22 rotates, it can drive the rotating rod 21 to rotate. Thus, the rotating rod 21 can drive the belt pulley 23, so that the belt pulley 23 can rotate. Therefore, the belt pulley 23 can transmit power to the rubber sleeve 14 under the action of the synchronous belt 24.

[0027] Working principle:

[0028] like Figures 1-5As shown, in use, the arc-shaped mandrel 11 and the adjusting handwheel 18 can be fastened together in a specific way. Then, the other end of the arc-shaped mandrel 11 is fitted into the mounting groove on the end cover 19. Next, the arc-shaped mandrel 11 is securely connected to the mounting frame of the gluing machine using bolts. At this time, the paper is conveyed from the bottom of the rubber sleeve 14 and contacts the rubber sleeve 14. Then, the hand rope wheel 22 is driven in a predetermined manner, causing it to rotate. The hand rope wheel 22 is located on the bearing 25. With proper coordination, the rotating rod 21 and the pulley 23 can be driven to rotate simultaneously. At this time, the pulley 23 can drive the rubber sleeve 14 through the synchronous belt 24, so that the rubber sleeve 14 can drive the roller sleeve 12 to rotate. The roller sleeve 12 can rotate smoothly with the cooperation of the bearing 13. Thus, the rubber sleeve 14 can smooth out the wrinkles on the conveyed paper under the action of the spiral groove 15 opened on its outer surface, so that the wrinkles on the paper can be eliminated, thereby ensuring the quality of paper production.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way.
