Abstract
Description
Technical Field
[0001] This application relates to the field of disposable hygiene product manufacturing equipment, and more particularly to baby / adult diapers, baby / adult pull-up pants, women's sanitary pants, women's sanitary napkins, mini towels, panty liners, etc., specifically a folding device. Background Technology
[0002] In equipment used for manufacturing disposable hygiene products, a folding device is typically employed to fold raw materials or semi-finished products along their width (perpendicular to the flow direction) to a predetermined size. The folding device consists of a folding plate that supports the raw materials or semi-finished products for folding, and a folding plate that folds the raw materials or semi-finished products to the predetermined size, arranged sequentially along the flow direction. When folding disposable hygiene products of different sizes, the predetermined folding dimensions along the width direction vary, generally requiring the fabrication of folding plates of different sizes. This necessitates machine downtime for replacement, directly impacting production efficiency.
[0003] Furthermore, along the width direction, since there are no components on the folding plate and the wrapping plate to adjust the folding path of the raw materials or semi-finished products, the raw materials or semi-finished products are not fully flattened during the folding process, resulting in wrinkles along the width direction after folding. This reduces the folding effect and affects the quality of disposable hygiene products.
[0004] Therefore, it is necessary to propose solutions to the problems of existing technologies. Utility Model Content
[0005] The purpose of this application is to provide a folding device to solve the problems in the prior art where the folding plate needs to be frequently replaced when folding raw materials or semi-finished products to produce products of different sizes, and where the folding process cannot be fully flattened, resulting in wrinkles after folding.
[0006] To achieve the above objectives, this application adopts the following technical solution.
[0007] This application provides a folding device for manufacturing disposable hygiene products. The disposable hygiene products include a material to be folded that is continuously traction-conveyed along the flow direction. The material to be folded includes raw materials or semi-finished products. The folding device includes:
[0008] A folding plate is used to support the material to be folded in preparation for folding; the folding plate has a folding end located on the outer side in the width direction;
[0009] At least one path adjustment unit is provided along the flow direction, the path adjustment unit being disposed below the folding plate and having an adjustable angle relative to the folding end of the folding plate;
[0010] A folding plate, located downstream of the starting folding plate, is used to fold one side of the material to be folded to a predetermined size along the width direction;
[0011] The path adjustment unit includes a swinging component and a limiting component. The swinging component has a swinging part that protrudes outward relative to the starting end of the folding plate. The limiting component is used to limit the swinging part.
[0012] Along the flow direction, the initiating folding plate, the path adjustment unit, and the wrapping folding plate are arranged in sequence to form the folding path of the material to be folded.
[0013] In some possible implementations, the swing portion of the path adjustment unit forms an angle greater than 90° with the folding plate.
[0014] In some possible implementations, the swing member further includes a mounting portion and a shaft, the mounting portion being adjustablely connected to the underside of the folding plate, the shaft being disposed between the mounting portion and the swing member, and the swing member being rotatable about the shaft.
[0015] In some possible implementations, the mounting portion has an adjustment hole that is perpendicular to the folding end of the folding plate and can be adjusted in a direction parallel to the folding end of the folding plate.
[0016] In some possible implementations, the mounting portion has a reference hole and an adjustment hole, the adjustment hole being able to be rotated and adjusted around the center of the reference hole.
[0017] In some possible implementations, the limiting member is a screw that abuts against the swing portion.
[0018] In some possible implementations, the folding plate is provided with a folding angle α relative to the wrapping plate, wherein 90° < α < 180°.
[0019] In some possible implementations, the folding plate includes a fixed portion and a folding portion, the folding portion being arranged perpendicularly to the fixed portion, and the width of the folding portion gradually increasing from the upstream side to the downstream side.
[0020] In some possible implementations, the folding device further includes a base on which the fixing portion of the folding plate is mounted.
[0021] In some possible implementations, the folding device further includes an adjusting part and a mounting frame, the base being connected to the adjusting part and the adjusting part being mounted on the mounting frame.
[0022] This application provides a folding device. By providing at least one path adjustment unit located at the folding plate along the flow path, capable of adjusting the angle relative to the folding end of the folding plate, the raw materials or semi-finished products of disposable hygiene products are folded along the path formed by the folding plate, the path adjustment unit, and the folding plate. The path adjustment unit is located below the folding plate and includes a swinging component and a limiting component. The swinging part of the swinging component protrudes outward relative to the folding end of the folding plate, and the limiting component limits the swinging part after angle adjustment, thereby fixing the adjustment angle of the swinging part. By adjusting the angle of the path adjustment unit, the folding size of the raw materials or semi-finished products in the width direction can be changed, meeting the predetermined size required for folding different sizes, saving time on changing folding plates, and improving production efficiency. Simultaneously, the swinging part of the path adjustment unit forms an angle greater than 90° with the folding plate, allowing the raw materials or semi-finished products to be flattened during the folding process, thereby improving the situation where wrinkles occur along the width direction after folding and improving the quality of disposable hygiene products.
[0023] Therefore, by setting an adjustable path adjustment unit, the problem of frequent replacement of folding plates required by traditional folding devices when processing products of different specifications is solved, reducing production costs, improving equipment utilization and production continuity, and meeting the dual requirements of efficiency and quality in modern production.
[0024] Furthermore, compared to traditional folding paths (which only include a starting folding plate and a folding plate), this application creates a new folding path for raw materials or semi-finished products by setting a path adjustment unit. Since the size of the path adjustment unit is smaller than the starting folding plate, it reduces the contact area between the raw materials or semi-finished products and the manufacturing equipment to a certain extent, reduces friction during the folding process, and improves the smoothness of the folding process.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.
[0035] One embodiment of this application provides a folding device for manufacturing disposable sanitary products. These disposable sanitary products can be disposable diapers, women's sanitary pants, sanitary napkins, etc. For the specific structure of the disposable sanitary products in this embodiment, please refer to [reference needed]. Figures 1 to 3 As shown. The disposable hygiene product includes a material to be folded that is continuously traction-conveyed along the flow direction, wherein the material to be folded includes raw materials or semi-finished products, and the semi-finished products are formed during the manufacturing and processing of the disposable hygiene product.
[0036] The disposable hygiene product S in this embodiment is a disposable diaper, which has mutually perpendicular transverse, longitudinal, and thickness directions. The disposable diaper includes an outer covering layer S1 and an absorbent core S2 disposed inside the outer covering layer S1. The absorbent core S2, from top to bottom along its thickness direction, includes a leak-proof section S21, an absorbent surface layer S22, an absorbent layer S23, and a leak-proof bottom layer S24. The folding device of this application can be used to fold the leak-proof section S21, wherein the leak-proof section S21 includes two longitudinally extending side materials S211 and an elastic member S212, with the side materials S211 folding the elastic member S212 inside to form a leak-proof three-dimensional protective structure. The various materials of the absorbent core S2 of the disposable diaper in this embodiment can be bonded together using hot melt adhesive, or by hot pressing or ultrasonic technology. The flow direction of the folding device corresponds to the longitudinal direction of the disposable diaper, and the width direction corresponds to the transverse direction of the disposable diaper.
[0037] See Figures 4 to 6 As shown, one embodiment of this application provides a folding device, which includes a folding plate 1, a path adjustment unit 2, a base 3, a folding plate 4, an adjustment part 5, and a mounting frame 6. Along the flow direction, a leak-proof part S21 to be folded is conveyed upstream to the top of the folding plate 1. The folding plate 1 is used to support the material to be folded for folding preparation, and has a folding end 11 located on the outer side in the width direction. Along the flow direction, in order to ensure that the leak-proof part S21 can be folded under a certain required tension, in this embodiment, the folding plate 1 is set with a certain folding angle α relative to the folding plate 4, wherein the folding angle α satisfies: 90° < α < 180°. Specifically, the folding angle α can be 120°, 135°, 145°, or 160°, etc., which is set according to actual needs.
[0038] In this embodiment, a pair of anti-leakage parts S21 to be folded is positioned above the folding plate 1, conveyed along the folding angle of the folding plate 1, and then transported below the wrapping plate 4. In this embodiment, the pair of anti-leakage parts S21 to be folded need to be folded inward simultaneously along their farthest sides in the width direction, that is, folded inward simultaneously from dimension L to dimension L1 (this folding dimension L1 is preset in the design of the disposable hygiene product S), while also wrapping multiple elastic components S212 inside, thereby forming a pair of anti-leakage parts S21 that are folded and simultaneously have elasticity along the flow direction. The folding dimension L1 is set according to the size of the disposable hygiene product.
[0039] In order to adjust the folding size of the anti-leakage section S21 in the width direction to meet the predetermined size required for folding of different sizes, and to flatten the anti-leakage section S21 before folding to improve the folding quality, in the embodiments of this application, at least one path adjustment unit 2 is disposed below the folding plate 1 along the flow direction. The path adjustment unit 2 has an angle that can be adjusted relative to the folding end 11 of the folding plate 1. In this embodiment, the number of path adjustment units 2 along the flow direction is one. In other embodiments, the number of path adjustment units 2 can be two. Compared with a single path adjustment unit, when using two path adjustment units, the size of the path adjustment units can be set to be smaller, as long as it can meet the folding size L1 of multiple sizes. The specific size can be set according to the actual situation.
[0040] In this embodiment, the anti-leakage portion S21 is provided on both sides of the horizontal direction of the disposable sanitary product S. Therefore, correspondingly, in the folding device of the disposable sanitary product S manufacturing equipment, such as Figure 4 and Figure 5 As shown, the folding device includes a pair of path adjustment units along the width direction, which are respectively arranged on both sides of the process centerline.
[0041] The path adjustment unit 2 includes a swing member 21 and a limiting member 22. The swing member 21 has a swing portion 222, which protrudes outward relative to the starting end 11 of the starting plate 1. The limiting member 22 is used to limit the swing portion 222.
[0042] In this embodiment, the swing member 21 further includes a mounting portion 221 and a shaft 223. The mounting portion 221 is adjustablely connected to the lower part of the folding plate 1, and the swing portion 222 is connected to the mounting portion 221 via the shaft 223. Specifically, the shaft 223 is disposed between the mounting portion 221 and the swing portion 222, allowing the swing portion 222 to be rotated around the shaft 223. Since the mounting portion 221 is fixed to the folding plate 1, and the swing portion 222 can rotate relative to the mounting portion 221, the angle of the swing portion 222 can be adjusted. Furthermore, to achieve the desired effect, the swing portion 222 is configured to protrude outward relative to the folding end 11 of the folding plate 1.
[0043] Furthermore, in this embodiment, the mounting part 221 has an adjustment hole 10, which is provided perpendicular to the folding end 11 of the folding plate 1 and can be adjusted in a direction parallel to the folding end 11 of the folding plate 1, so that the contact surface between the swing part 222 and the anti-leakage part S21 is parallel to the folding end 11 of the folding plate 1.
[0044] In other partial embodiments, such as Figure 7As shown, the mounting part 221 has a reference hole 12 and an adjustment hole 13. The adjustment hole 13 can be rotated and adjusted around the center of the reference hole 12. The adjustment hole 13 rotates and adjusts along the reference hole 12 to meet the folding size of the anti-leakage part S21 of different sizes.
[0045] Continue reading Figures 4 to 6 In this embodiment, the limiting member 22 is a screw that abuts against the swing part 222. Limiting the swing part 222 by pressing it against the screw achieves the limiting effect, thereby fixing the adjustment angle of the swing part 222 and preventing arbitrary swinging of the swing part 222 during operation. In other embodiments, other limiting methods may be used, such as using a locking nut to fix the shaft 223, or using a snap-fit structure to position and limit the swing part 222.
[0046] In this embodiment, the swing part 222 of the path adjustment unit 2 forms an angle greater than 90° with the folding plate 1, so that the anti-leakage part S21 can be flattened during the folding process, thereby improving the situation where the anti-leakage part S21 wrinkles along the width direction after folding, and thus improving the quality of disposable hygiene products S.
[0047] In this embodiment, the folding plate 4 is located downstream of the starting folding plate 1 and is used to fold one side of the material to be folded to a predetermined size along the width direction. Specifically, the folding plate 4 includes a fixing part 41 and a folding part 42. The folding part 42 is arranged perpendicularly to the fixing part 41. The fixing part 41 is mounted on the base 3. In this embodiment, there is a pair of bases 3, located on both sides of the flow center line. A pair of anti-leakage parts S21 are conveyed between the pair of bases 3 and the pair of folding parts 42 of the folding plate 4. The width of the folding part 42 gradually increases from the upstream side to the downstream side. The folding part 42 is connected along the downstream side of the starting folding plate 1, so that one end of the anti-leakage part S21 along the width direction is gradually covered by the folding plate 4, thereby completing the entire folding process. In this folding device, the starting folding plate 1, the path adjustment unit 2, and the folding plate 4 are arranged sequentially along the flow direction to form the folding path of the anti-leakage part S21 (the material to be folded). When the angle of the swing part 222 of the path adjustment unit 2 is adjusted, the folding path changes, thereby satisfying the folding size L1 of the anti-leakage part S21 in different sizes.
[0048] Compared to the traditional folding path (which only includes the starting folding plate 1 and the folding plate 4), the path adjustment unit 2 constitutes a new folding path for the anti-leakage section S21. Since the path adjustment unit 2 is smaller than the starting folding plate 1, it reduces the contact area between the anti-leakage section S21 and the manufacturing equipment to a certain extent, lowering the frictional resistance during the folding process and improving the smoothness of the folding process. It should be noted that the anti-leakage section S21 is pulled downstream by a (indirect) driving force from the downstream side. During this folding process, there will be significant friction between the anti-leakage section S21 and the starting folding plate 1.
[0049] In order to allow the anti-leakage section S21 to be adjusted individually in the width direction, the folding device in this embodiment further includes an adjusting section 5 and a mounting bracket 6. (See also...) Figure 8 As shown, a pair of bases 3 are respectively connected to a pair of adjusting parts 5, and the pair of adjusting parts 5 are mounted on the mounting bracket 6. The adjusting part 5 includes a slide rail and a slider, which cooperate to form an adjustment structure. When the operating handle is turned, the slider in the adjusting part 5 moves along the slide rail in the width direction, and drives the base 3 through the adjusting part 5 to adjust the position of the anti-leakage part S21 in the width direction, thereby accommodating the position of multiple anti-leakage parts S21 of different sizes.
[0050] It should be noted that, in Figure 8 In the illustrated embodiment, the base 3 and the adjusting part 5 in the folding device are both a pair, enabling simultaneous folding of the anti-leakage part S21. However, in other embodiments, depending on actual processing needs, the number of components such as the base 3 and the adjusting part 5 in the folding device can be one, meaning that only one side of the anti-leakage part S21 is folded.
[0051] The folding device described in this application can change the folding size of raw materials or semi-finished products in the width direction through the angle adjustment of the path adjustment unit 2. This can meet the predetermined size required for folding different sizes, thereby saving time for changing folding plates and improving production efficiency. At the same time, the swing part 222 of the path adjustment unit 2 forms an angle greater than 90° with the folding plate 1, so that the raw materials or semi-finished products can be flattened during the folding process, thereby improving the situation of wrinkles in the width direction of the raw materials or semi-finished products after folding and improving the quality of disposable hygiene products.
[0052] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The features, structures, or characteristics described above can be combined in any suitable manner in one or more embodiments.
[0053] It is understood that those skilled in the art, guided by the above embodiments, can combine various implementation methods in the above embodiments to obtain technical solutions with multiple implementation methods. The above descriptions are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
