AI Technical Summary
In existing technologies, hygiene product materials require frequent roll changes during process transfer, resulting in low production efficiency. In particular, the length of the non-woven fabric rolls after slitting is relatively short, leading to frequent and time-consuming unloading, which affects the efficiency of subsequent processes.
The spiral winding mechanism uses a moving mechanism to make the winding roller reciprocate along the slide rail, so that the nonwoven fabric is spirally wound around the surface of the paper tube. Combined with the tension adjustment and pressing mechanism, it ensures that the nonwoven fabric is tightly wound and reduces the unloading frequency.
Extending the length of nonwoven fabric rolls reduces the frequency of unloading and material replacement, improves the production efficiency of hygiene products, and ensures the stability of winding quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding equipment technology, specifically to a winding mechanism for sanitary product materials. Background Technology
[0002] Currently, in the manufacturing process of hygiene products such as diapers and sanitary napkins, the final product needs to go through multiple processes. When transferring between processes, the material is generally rotated and rolled into a disc shape for easy use in the next process. However, the length of a single roll of this type of material is generally not very long, and the machine needs to be stopped frequently to replace it with a new roll, resulting in a lot of production time being wasted in the roll replacement process, which affects the production efficiency. In particular, for non-woven fabrics that are slit and then rolled, the wide non-woven fabrics are cut into several parts and several rolls of smaller non-woven fabrics during the slitting process. If the length of a single roll of non-woven fabric is short, the non-woven fabric rolls need to be unloaded frequently after slitting and rolling, and the number of non-woven fabric rolls unloaded each time is large. The workload of the unloading process is large and it takes a lot of time, which can easily affect the efficiency of subsequent processes. Utility Model Content

Detailed Implementation
[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.
[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 A winding mechanism for sanitary product materials includes a winding roller 1, a fixed bracket 2, and a moving mechanism 3. The winding roller 1 is movably connected to the fixed bracket 2. A first motor 4 that rotates the winding roller 1 is provided on one side of the fixed bracket 2. The moving mechanism 3 is located at the bottom of the fixed bracket 2. The moving mechanism 3 includes the following structure: a moving slider 31, which is fixedly connected to the fixed bracket 2. A matching moving slide rail 32 is mounted on the bottom of the moving slider 31. A second motor 33 is provided on one side of the moving slide rail 32. A moving screw 34 is provided at the output end of the second motor 33. A moving nut 35 is sleeved on the surface of the moving screw 34. The outer side of the moving nut 35 is fixedly connected to the fixed bracket 2.
[0024] This utility model discloses a winding mechanism for winding sanitary product materials by spiral winding. The winding mechanism is mainly used to wind up the slit non-woven fabric. The fixed bracket 2 serves as the main support structure in the winding mechanism. Components such as the winding roller 1 and the first motor 4 are installed on the fixed bracket 2. A bearing is provided at the connection between the winding roller 1 and the fixed bracket 2. The winding roller 1 is used to fix the paper tube at the core of the non-woven fabric roll. The paper tube is sleeved on the surface of the winding roller 1. The first motor 4 drives the winding roller 1 to rotate and makes the paper tube rotate synchronously, thereby gradually winding up the non-woven fabric wrapped on the surface of the paper tube. The slit non-woven fabric is gradually wrapped around the surface of the paper tube to form a non-woven fabric roll.
[0025] Furthermore, the winding roller 1, the moving screw 34, and the moving slide rail 32 extend in the same direction. The moving screw 34 and the moving nut 35 together form a structure similar to a ball screw. The second motor 33 is used to drive the moving screw 34 to rotate. Since the moving nut 35 is fixed to the fixed bracket 2 and cannot rotate, the moving nut 35 will reciprocate along the extension direction of the moving screw 34 and drive the fixed bracket 2 to move synchronously. During the winding process of the winding roller 1 winding the nonwoven fabric, the fixed bracket 2 reciprocates along the extension direction of the moving screw 34. The movement allows the nonwoven fabric to be spirally wound onto the surface of the paper tube, increasing the width of the nonwoven fabric roll after winding. It also allows for the winding of longer nonwoven fabric rolls of the same thickness, meaning that the length of nonwoven fabric in a single roll is longer. As the length of nonwoven fabric in a single roll increases, the time interval for unloading the nonwoven fabric roll will be extended, and the frequency of changing the nonwoven fabric roll in other process equipment will also decrease. This reduces the downtime of processing equipment due to unloading and material changing, which is beneficial to improving the efficiency of the process of using nonwoven fabric to make hygiene products.
[0026] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 4 The fixed bracket 2 consists of two adjacent fixed plates 21, each fixed plate 21 is movably connected to a winding roller 1, and the first motor 4 is located between the two fixed plates 21. There are two first motors 4, which are matched one by one with the two winding rollers 1. With the above structure, the winding mechanism can simultaneously wind up two rolls of non-woven fabric, and the moving mechanism 3 can simultaneously make the two fixed plates 21 move synchronously. That is, the two winding rollers 1 can be reciprocated by a second motor 33 to wind up the non-woven fabric, reducing the number of drive devices such as the second motor 33, which is beneficial to reducing the manufacturing cost of the winding mechanism.
[0027] In addition, after the first motor 4 is placed between the two fixed plates 21, the take-up roller 1 extends away from the two fixed plates 21. Users can replace the take-up roller 1 of different lengths according to actual needs to obtain non-woven fabric rolls of different widths, which can be better matched with other processing equipment. By replacing the take-up roller 1 with a shorter length, the space occupied by the take-up mechanism can be avoided.
[0028] As one of the preferred embodiments of this utility model, refer to Figure 5 , Figure 6 The top of the fixed bracket 2 is provided with a tension adjustment mechanism 5 located above the take-up roller 1. The tension adjustment mechanism 5 includes the following structure: a first tension roller group 51, a second tension roller group 52 provided on one side of the first tension roller group 51, both the first tension roller group 51 and the second tension roller group 52 are composed of at least two tension rollers 53, the tension rollers 53 in the second tension roller group 52 are movably connected to a swing rod 54, the swing rod 54 is movably connected to the fixed bracket 2, and an adjustment rod 55, one end of the adjustment rod 55 is fixedly connected to the fixed bracket 2, and the other end is provided with a movable rod 56 movably connected to the swing rod 54. The movable rod 56 reciprocates along the extension direction of the adjustment rod 55.
[0029] With the above structure, it should be noted that the nonwoven fabric needs to pass through the tension adjustment mechanism 5 before being wound around the paper tube surface of the take-up roller 1 for winding. The tension rollers 53 in the first tension roller group 51 and the second tension roller group 52 are staggered. The tension rollers 53 in the same tension roller group are positioned on the same straight line. The nonwoven fabric extends in an S-shape between the tension rollers 53 in the two tension roller groups. After passing through the two tension roller groups, the nonwoven fabric is wound around the paper tube surface. The tension roller 53 in the first tension roller group 51 is movably connected to the fixed bracket 2 through bearings. The tension roller 53 in the second tension roller group 52 is movably connected to the swing rod 54 through bearings. The swing rod 54 is movably connected to the fixed bracket 2 through bearings and shaft.
[0030] It should be further explained that the tension adjustment mechanism 5 is mainly used to stabilize the tension of the nonwoven fabric during the winding process. In the tension adjustment mechanism 5, the adjusting rod 55 and the movable rod 56 together form a pneumatic active adjusting rod. The adjusting rod 55 is equipped with a pneumatic cylinder, and the movable rod 56 reciprocates by external compressed air. A pressure sensor is installed between the movable rod 56 and the adjusting rod 55. When the tension of the nonwoven fabric increases, the force exerted by the nonwoven fabric on the two tension roller groups increases, and the pressure exerted by the second tension roller group 52 on the movable rod 56 increases. At this time, the pressure sensor will detect the increase in pressure, and the movable rod 56 needs to move towards the adjusting rod 55, so that the swing rod 54 moves towards the first tension roller group 51, reducing the distance between the two tension roller groups. This can make the nonwoven fabric loosen and reduce its tension. Conversely, by increasing the distance between the two tension roller groups, the tension of the nonwoven fabric can be increased. By stabilizing the tension of the nonwoven fabric through the tension adjustment mechanism 5, the width of the nonwoven fabric can be prevented from changing during the winding process, which is beneficial to improving the quality stability of the manufactured sanitary products.
[0031] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 2 , Figure 4 A pressing mechanism 6 is provided on one side of the fixed bracket 2. The pressing mechanism 6 includes the following structure: a connecting shaft 61, which is movably connected to the fixed bracket 2; a pressing rod 62 on one side of the connecting shaft 61; a pressing roller 63 matching the winding roller 1 movably connected to the end of the pressing rod 62; and an inlet roller 64 on one side of the pressing rod 62, which is located between the connecting shaft 61 and the pressing roller 63. The nonwoven fabric to be wound is wound around the surface of the paper tube after the direction is adjusted by the inlet roller 64. The end of the connecting shaft 61 is movably connected to the fixed bracket 2 through a bearing. The pressing mechanism 6 swings through the connecting shaft 61, causing the pressing rod 62 and the pressing roller 63 to swing around the connecting shaft 61 as the axis, and causing the pressing roller 63 to press on the surface of the nonwoven fabric wound on the surface of the paper tube. This can improve the tightness of the nonwoven fabric roll after winding and prevent the nonwoven fabric roll from being too loose and increasing its space occupation.
[0032] As one of the preferred embodiments of this utility model, refer to Figure 1 , Figure 4 The output end of the first motor 4 is provided with a drive gear 41, and the take-up roller 1 is provided with a transmission gear 42 near the end of the first motor 4. The drive gear 41 and the transmission gear 42 are wound together with a transmission belt 43. The drive gear 41, the transmission gear 42 and the transmission belt 43 together form a transmission structure. The first motor 4 causes the take-up roller 1 to rotate through this transmission structure. This transmission structure can keep the transmission process efficient and stable.
[0033] In summary, this utility model discloses a winding mechanism for winding nonwoven fabric by spiral winding. The winding mechanism rotates the winding roller 1 to gradually wrap the nonwoven fabric around the surface of the paper tube to obtain a nonwoven fabric roll. During the winding process, the moving mechanism 3 causes the winding roller 1 to reciprocate along the extension direction of the moving slide rail 32, so that the nonwoven fabric is spirally wound around the surface of the paper tube. This allows for the winding of longer nonwoven fabric rolls, thereby reducing the frequency of unloading and material replacement of the nonwoven fabric rolls and improving the efficiency of the process of using nonwoven fabric to make sanitary products.
[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
