DETAILED DESCRIPTION

[0018] Please refer to Figure 1 , an embodiment of the present invention provides a shaping device for shaping the cut products to facilitate subsequent processing of the products, and the subsequent processing includes folding, bagging, etc. It can be understood that the products are usually disposable absorbent products, and the disposable absorbent products usually include a stacked surface layer, an absorption layer and a bottom layer. The surface layer is usually liquid-permeable and is close to the skin side when in use. The bottom layer is usually liquid-impermeable and is used to prevent body fluids from passing through the disposable absorbent products to contaminate clothes or skin. The absorption layer is usually used to absorb and store body fluids. Specifically, the disposable absorbent products can be diapers, sanitary napkins, and nursing pads.

[0019] The shaping device includes a clamping and conveying module 20 and a shaping module 30 .

[0020] The clamping and conveying module 20 includes a supporting conveying component 21 and a pressing conveying component 22 located above the supporting conveying component 21. At the same time, the supporting conveying component 21 and the pressing conveying component 22 form a clamping and conveying channel for clamping and conveying the product. The clamping and conveying refers to the pressing and conveying component 22 and the supporting conveying component 21 maintaining a clamping state on the product during the conveying process.

[0021] In this embodiment, the supporting conveying assembly 21 includes a lower conveyor belt 212 wound on a number of supporting rollers, wherein the supporting rollers include a lower guide wheel 211 extending in the upstream direction and a lower driving wheel 213 located downstream of the lower guide wheel 211, and the lower conveyor belt 212 includes a supporting conveying surface 210 for supporting products. At the same time, the pressing conveying assembly 22 includes an upper conveyor belt 222 wound on a number of supporting rollers, wherein the supporting rollers include a front guide wheel 221 extending in the upstream direction and an upper driving wheel 223 located downstream of the front guide wheel 221, and the upper conveyor belt 222 includes a pressing surface, and the pressing surface and the supporting conveying surface 210 apply pressure to the product to form a clamp.

[0022] Typically, a slitting module 10 is also included upstream of the clamping and conveying module 20. The slitting module 10 is used to slit continuous products into independent products. The slitting module 10 includes a cutter roller with a cutter, a bottom roller, and a gap between the cutter roller and the bottom roller. When the continuous product passes through the gap, the cutter cuts the product. The supporting conveying assembly 21 is arranged adjacent to the gap to receive the slit products. It can be understood that in this case, the upstream direction is the direction toward the slitting module 10. At the same time, the lower guide wheel 211 is closer to the gap than the front guide wheel 221, so that the supporting conveying surface 210 can be closer to the slitting module 10, thereby facilitating the supporting conveying surface 210 to receive the slit products. In addition, under this arrangement, a notch is formed between the front guide wheel 221 and the gap, which also enables the product to more easily enter the clamping and conveying channel and be clamped and conveyed by the clamping and conveying assembly.

[0023] In addition, an adjustment device may be provided between the supporting conveying assembly 21 and the holding conveying assembly 22 to adjust the distance between the supporting conveying surface 210 and the holding surface to adapt to different products.

[0024] Furthermore, the supporting conveying assembly 21 and the holding conveying assembly 22 also include an adsorption device to keep the product in contact with the supporting conveying surface 210 and the holding surface during the conveying process.

[0025] The shaping module 30 is arranged downstream of the clamping and conveying module 20, and includes a middle shaping component 32 and a side shaping component, wherein the middle shaping component 32 is used to shape the middle area of ​​the product, and the side shaping component is used to shape the side of the product. The middle refers to the middle area of ​​the product in the width direction. Usually, when the product is a disposable absorbent product, the middle corresponds to the area of ​​the absorbent layer, and the side refers to the area of ​​the product located on both sides of the middle area in the width direction.

[0026] Please refer to Figure 2-Figure 5 The middle shaping component 32 includes an upper pressing roller 321 and a pair of lower rollers located below the upper pressing roller 321. In this embodiment, the upper pressing roller 321 and the pair of lower pressing rollers are arranged in a triangular shape. The triangular arrangement means that the line connecting the axis of the upper pressing roller 321 and the pair of lower rollers is a triangle on the vertical plane. More specifically, the pair of lower rollers have the same size, so that the triangle is an isosceles triangle.

[0027] For the convenience of description, the pair of lower rollers are respectively referred to as the first lower roller 322 and the second lower roller 323. The upper pressure roller 321 and the first lower roller 322 and the second lower roller 323 respectively include a first roller pressure area and a second roller pressure area. The product will pass through the first roller pressure area and the second roller pressure area in turn to shape the middle area of ​​the product.

[0028] Furthermore, the first roller pressing area and the second roller pressing area have the same height in the vertical direction.

[0029] Furthermore, the upper pressing roller 321 also includes a roller pressure adjustment device for adjusting the gap between the upper pressing roller 321 and the first lower roller 322 and the second lower roller 323, so as to adjust the pressure of the middle shaping component 32 when rolling the product. In this embodiment, the roller pressure adjustment device includes a slide groove 312 provided on the frame 31 and a slide 311 matched with the slide groove 312. The upper pressing roller 321 is rotatably provided on the slide 311, and the slide 311 is configured to move along the extension direction of the slide groove 312 to adjust the position of the slide 311 and the upper pressing roller 321 provided on the slide 311. Specifically, the machine The frame 31 is also provided with a cross beam 313, and an adjusting rod 314 is provided between the slide 311 and the cross beam 313. In this embodiment, the adjusting rod 314 is a screw rod, one end of the screw rod is rotatably connected to the cross beam 313, and the other end is connected to the slide 311 by a thread. When the screw rod is rotated, the slide 311 moves along the axial direction of the screw rod. It can be understood that the slide groove 312 is arranged in the vertical direction, so that the slide 311 and the upper pressure roller 321 arranged on the slide 311 move in the vertical direction, thereby adjusting the gap between the upper pressure roller 321 and the first lower roller 322 and the second lower roller 323.

[0030] The side shaping component includes a rear guide wheel 332 located downstream of the upper pressure roller 321 and a side shaping belt 331 wound around the front guide wheel 221 and the rear guide wheel 332, and at least a portion of the side shaping belt 331 is wrapped around the upper pressure roller 321 and moves synchronously when the upper pressure roller 321 moves. In a specific embodiment, there is a pair of side shaping belts 331, which are respectively arranged on both sides of the middle shaping component 32 to shape the two sides of the product in the two side directions. At the same time, the side shaping belt 331 can be a flat belt or an O-belt.

[0031] In practice, it is found that through the above-mentioned arrangement, on the one hand, the clamping and conveying module 20 actually flattens the product during the process of clamping and conveying the product. On the other hand, the middle area of ​​the product will pass through the first roller pressure zone and the second roller pressure zone in sequence, so that the middle area of ​​the product is shaped by roller pressure, and because the product actually passes through the two roller pressure zones in a wavy and tortuous manner, the softness of the product is also improved. On the third hand, it can be seen that the side shaping belt 331 extends from the front guide wheel 221 to the lower vertex 3314 of the upper pressure roller 321, so that the side shaping belt 331 continuously applies a slight downward pressure on the side of the product from the front guide wheel 221 to the upper pressure roller 321, so that the upturned part of the edge of the product after slitting is pressed downward, and because a flat belt or an O-shaped belt is used, even if there are some raised or wrinkled parts, they can be flattened by the flat belt or the O-shaped belt to achieve side shaping. In addition, since the side shaping belt 331 is driven and kept synchronized by the upper pressure roller 321, the side shaping belt 331 maintains the same force as the upper pressure roller 321 on the middle part when applying force to the side part to shape it, so as to avoid the two from being out of sync and causing secondary wrinkles. The lower vertex 3314 is the lowest point of the upper pressure roller 321 in the vertical direction. It can be understood that the first lower roller 322 includes a first vertex 3221, and the second lower roller 323 includes a first vertex 3231. The position of the lower vertex 3314 in the vertical direction should be lower than the first vertex 3221 and the first vertex 3231, so that when the side shaping belt 331 is shaping the product, when the middle part of the product is located at the first vertex 3221 and the first vertex 3231, the force applied by the side shaping belt 331 on the side makes the side part slightly lower than the middle part, thereby further flattening and shaping the side part of the product without warping or rebounding.

[0032] In addition, we can see that the side shaping belt 331 actually passes through the upper pressing roller 321, which also helps the transportation or movement of the product.

[0033] During the study, it was found that when the shaping device of this embodiment is used to shape the product and then carry out post-processing such as conveying and folding, the product is less likely to have wrinkles, bulges, and warping by more than 82% compared with the post-processing process of directly conveying and folding after slitting. At the same time, the surface feel of the product is improved. When the surface is subjected to sensory testing, the feel evaluation index is improved by 5.5%.

[0034] Furthermore, the side shaping belt 331 is kept in contact with the lower vertex 3314. Figure 5 ,exist Figure 5A simplified schematic diagram of the side shaping assembly is shown in the figure, wherein at least a portion of the upper portion of the side shaping belt 331 is covered on the upper pressure roller 321, so that when the upper pressure roller 321 rotates, the side shaping belt 331 is synchronously driven to move, and at the same time, the side shaping belt 331 is kept in contact with the lower vertex 3314 of the upper pressure roller 321, and the side shaping belt 331 also includes a shaping front section 3312 located between the front guide wheel 221 and the lower vertex 3314 and a shaping rear section 3313 located between the lower vertex 3314 and the rear guide wheel 332, and the shaping front section 3312 is inclined to the supporting conveying surface 210, so that the shaping front section 3312 can continuously apply pressure to the side, and the pressure gradually increases, thereby achieving a shaping effect.

[0035] Furthermore, the portion of the side shaping belt 331 that is wrapped around the upper pressure roller 321 is called the wrapping section 3311, and the wrapping angle of the wrapping section 3311 is α, then α=90°~135°, so that the upper pressure roller 321 can better drive the side shaping belt 331 to move, more preferably, α=100°~115°.

[0036] Furthermore, an included angle β is formed between the front shaping section 3312 and the supporting conveying surface 210 , and β=1.5° to 4°, more preferably, β=1.8° to 3°.

[0037] Furthermore, an included angle γ is formed between the rear shaping section 3313 and the supporting conveying surface 210 , and γ=3° to 8°, and more preferably, β=4.5° to 7.5°.

[0038] At the above-mentioned angle, on the one hand, the side shaping belt 331 can shape and flatten the side of the product, and on the other hand, the product can easily separate from the shaping module 30 and enter the next functional module, such as the rear conveying module 40. When the rear conveying module 40 includes a rear conveying surface 400, the angle between the rear shaping section 3313 and the rear conveying surface 400 is also 3° to 8°.

[0039] Please refer to Figure 1 The upper driving wheel 223 is arranged between the front supporting wheel and the upper pressure roller 321, and the linear speed of the upper driving wheel 223 is the same as the linear speed of the upper pressure roller 321, so that the upper conveyor belt 222 and the side shaping belt 331 move synchronously.

[0040] Furthermore, at least a portion of the side shaping belt 331 is attached to the upper driving wheel 223 so that when the upper driving wheel 223 moves, the side shaping belt 331 is also driven to move synchronously.

[0041] Furthermore, in order to ensure that the wrapping section 3311 of the side shaping belt 331 has a sufficient wrapping angle on the upper pressure roller 321, the shaping module 30 also includes a left guide wheel 333 and a right guide wheel 334 arranged on the left and right sides of the upper pressure roller 321. The side shaping belt 331 is wound from bottom to top around the left guide wheel 333 to form the wrapping section 3311 and then passes around the right guide wheel 334 from bottom to top, so that the wrapping section 3311 has a sufficient wrapping angle.

[0042] Furthermore, an adjustment frame 3331 is provided on the frame 31 for adjusting the positions of the left guide wheel 333 and the right guide wheel 334 in the vertical direction, thereby adjusting the covering angle. In this embodiment, the adjustment frame 3331 located on the left and the adjustment frame 3331 located on the right have basically the same structure. Therefore, in the following description, only the left adjustment frame 3331 for adjusting the left guide wheel 333 is described, and the right adjustment frame 3331 for adjusting the right guide wheel 334 is not described in detail.

[0043] The adjustment frame 3331 includes a connecting portion and an extending portion, wherein the left guide wheel 333 is arranged on the extending portion, and the connecting portion is provided with at least two first adjustment slots 3332 arranged in the vertical direction. Each first adjustment slot 3332 is penetrated by a bolt and fixed on the frame 31. When the bolt is loosened, the connecting portion can move along the extension direction of the first adjustment slot 3332, thereby adjusting the overall position of the adjustment frame 3331 in the vertical direction. It can be understood that the provision of at least two first adjustment slots 3332 can limit the angle of the connecting portion to ensure that the connecting portion maintains the original angle after moving along the extension direction of the first adjustment slot 3332.

[0044] Furthermore, a limiting device is provided on the frame 31 for limiting the position of the connecting part. Specifically, the limiting device includes a limiting bolt which is vertically arranged and one end of which contacts the connecting part in the vertical direction. The limiting bolt is threadedly connected to a fixed bracket. When the position of the connecting part in the vertical direction is adjusted, the limiting bolt is adjusted to a position that contacts the connecting part, thereby ensuring that the position of the connecting part in the vertical direction remains unchanged.

[0045] Furthermore, the overhanging portion also includes a second adjusting slot 3333, the left guide wheel 333 includes a shaft rod, the shaft rod is passed through the second adjusting slot 3333, a cross bar 3334 and a fine-tuning bolt 3335 passed through the cross bar 3334 are provided on the upper side of the second adjusting slot 3333, one end of the fine-tuning bolt 3335 abuts against the shaft rod to adjust the tension of the side molding belt 331. It can be understood that the cross bar 3334 includes a thread, and the fine-tuning bolt 3335 is threadedly connected to the cross bar 3334. At the same time, the second adjusting slot 3333 is also set in the vertical direction.

[0046] Furthermore, the position of the rear guide wheel 332 in the vertical direction is adjustable.

[0047] Furthermore, a support rod 3321 is provided on the frame 31, a swing frame 3322 is provided on the support rod 3321, and the rear guide wheel 332 is provided at the end of the swing frame 3322. The swing frame 3322 is configured to rotate along the support rod 3321, so that the position of the rear guide wheel 332 in the vertical direction is adjustable, thereby adapting to products of different thicknesses and adapting to different rear conveying modules 40.

[0048] Furthermore, a locking bolt 3323 is also provided on the swing frame 3322. The swing frame 3322 includes a central hole and an open groove provided on one side of the central hole. The locking bolt 3323 is threadedly connected to one side of the open groove to change the aperture of the central hole of the swing frame 3322 so as to clamp the support rod 3321 passing through the central hole.

[0049] Furthermore, an upper guide wheel 335 is provided on the swing frame 3322 , and the upper guide wheel 335 is located above the right guide wheel 334 , so that the side shaping belt 331 can be stably wrapped around the right guide wheel 334 and the rear guide wheel 332 .

[0050] Furthermore, a transition wheel 34 is provided between the rear guide wheel 332 and the lower roller, and the transition wheel 34 is used to support the product passing through the second roller pressure zone from bottom to top.

[0051] Furthermore, the transition wheel 34 further includes a vertical adjustment device 341 for adjusting the position of the transition wheel 34 in the vertical direction.
