Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] In the description of this invention, it should be understood that the terms "vertical," "parallel," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] In view of the current shortcomings in the production of non-woven hygiene products, such as low production flow due to low automation, which ultimately leads to poor neatness after cutting and folding, this application provides a cutting and folding device and production equipment including the same, which can effectively improve the above situation.

[0040] Example 1

[0041] Reference Figure 1-6As shown, this embodiment provides a cutting and folding device 100, which includes a flattening mechanism 10, a cutting mechanism 20, a first conveying mechanism 30, a folding mechanism 40, and a second conveying mechanism 50 arranged sequentially to cut and fold sanitary products made of non-woven fabric. This cutting and folding device 100 is suitable for multi-row non-woven sanitary product production equipment, used for cutting and vertically folding raw materials, and its feed end is connected to a feeding device (not shown) or the previous folding device (not shown).

[0042] In this embodiment, the cutting and folding device 100 further includes a support mechanism 60, which includes a support body 61 and two side plates 62 respectively disposed on opposite sides of the support body. The flattening mechanism 10, cutting mechanism 20, first conveying mechanism 30, folding mechanism 40, and second conveying mechanism 50 are respectively disposed on the two side plates 62. Of course, in the complete production equipment, a raw material feeding device or a turning device is usually provided before the cutting and folding device 100, so the cutting and folding device 100 also includes a guide member 70 disposed at its feeding end, the two ends of which are respectively connected to the support mechanism 60 for guiding the raw material.

[0043] Specifically, such as Figure 3 As shown, the flattening mechanism 10 includes a first traction component 11, a flattening component 12, and a second traction component 13. After the raw material is pulled by the first traction component, it is tensioned by the flattening component 12 and then pulled by the second traction component to obtain the flattened raw material.

[0044] More specifically, the first traction assembly 11 includes a first active roller 111 and a first passive roller 112 arranged in parallel, and the second traction assembly 13 includes a second active roller 131 and a second passive roller 132 arranged in parallel. The first active roller 111 and the second active roller 131 are respectively connected to a drive structure (not shown). The first active roller 111 rotates under the drive mechanism. When the raw material passes through the first traction assembly 11, the raw material adheres to the first active roller 111 and the first passive roller 112. Under the action of friction, the first active roller 111 drives the raw material and the first passive roller 112 to rotate synchronously and in opposite directions, so as to achieve traction of the raw material.

[0045] The flattening assembly 12 includes a first flattening member 121 and a second flattening member 122 arranged in parallel. The flattening mechanism 10 also includes a first synchronous belt 14, one end of which is connected to a first driving roller 111, and the other end to the first flattening member 121, so that the first driving roller 111 drives the first flattening member 121 to rotate synchronously. The flattening mechanism 10 also includes a second synchronous belt 15, one end of which is connected to a second driving roller 131, and the other end to the second flattening member 122, so that the second driving roller 131 drives the second flattening member 122 to rotate synchronously. The flattening assembly 12 also includes a third synchronous belt 16, one end of which is connected to a first passive roller 112, and the other end to the second driving roller 131, so that the second driving roller 131 provides kinetic energy to the first passive roller 112 to enable its rotation.

[0046] The discharge end of the first flattening component 121 is connected to the feed end of the second flattening component 122. That is, when the raw material passes through the flattening assembly 12, the raw material passes sequentially through the discharge end of the first flattening component 121 and the second flattening component 122, and tensioning and flattening are achieved through the action of the two. Preferably, the linear speed of rotation of the first flattening component 121 is less than the linear speed of rotation of the second flattening component 122, so as to achieve effective tensioning of the product in the flattening mechanism.

[0047] Specifically, the first driving roller 111 includes a first driving wheel at its end, the first flattening member 121 includes a first driven wheel at its end, and the two ends of the first synchronous belt 14 are respectively sleeved on the first driving wheel and the first driven wheel. The second driving roller 131 includes a second driving wheel at its end, the second flattening member 122 includes a second driven wheel at its end, and the two ends of the second synchronous belt 15 are respectively sleeved on the second driving wheel and the second driven wheel. The first driving wheel and the second driving wheel have the same diameter, while the diameter of the first driven wheel is smaller than that of the second driven wheel, so that the linear velocity of the first flattening member 121 is less than the linear velocity of the second flattening member 122.

[0048] It should be noted that the first traction component 11, the flattening component 12 and the second traction component 13 have a certain width to enable the synchronous production of multi-row products and to meet the production needs of products of different sizes.

[0049] like Figure 1-2As shown in Figure 4, the feed end of the cutting mechanism 20 is connected to the discharge end of the flattening mechanism 10, and includes a cutting blade assembly 21 for cutting the flattened raw material to obtain the cut product. Specifically, the cutting blade assembly 21 includes a cutting mounting plate 22, a cutting active blade roller 23 and a cutting passive blade roller 24 respectively rotatably connected to the cutting mounting plate 22. The cutting active blade roller 23 and the cutting passive blade roller 24 are arranged in parallel and rotate towards each other. When the flattened raw material passes between the cutting active blade roller 23 and the cutting passive blade roller 24, it is cut to a specified length. The mounting plate 22 is provided on a side plate 62. The surface of the cutting active blade roller 23 is provided with a blade head (not shown) arranged along its axial direction. The cutting active blade roller 23 passes through the mounting plate 22 and is connected to a drive mechanism (not shown). The drive mechanism drives the cutting active blade roller 23 to rotate, and when the blade head faces the product, the product is cut under the action of the blade head and the cutting passive blade roller 24.

[0050] It should be noted that the cutting blade assembly 21 has a certain width to enable the synchronous production of multi-row products and to meet the production needs of products of different sizes.

[0051] like Figure 1-2 As shown in Figure 5, the infeed end of the first conveying mechanism 30 is connected to the discharge end of the cutting mechanism 20. It includes a first conveyor belt 31, at least one second conveyor belt 32 opposite to the first conveyor belt 31, a first conveyor roller group 33, and a second conveyor roller group 34. The first conveyor belt 31 is wound around the first conveyor roller group 33, and at least one second conveyor belt 32 is wound around the second conveyor roller group 34. The first conveyor belt 31 and at least one second conveyor belt 32 run in the same direction to form a first conveying channel for conveying the cut products. When the cut products are conveyed in the first conveying channel, the first conveyor belt 31 and the second conveyor belt 32 clamp the cut products to achieve product conveying. The second conveyor belt 32 is a strip conveyor belt with a width smaller than that of the first conveyor belt 31. It should be noted that this device 100 is suitable for multi-row production devices. The number of second conveyor belts 32 is not less than the minimum number of rows in multi-row production, and the spacing between adjacent second conveyor belts 32 is adjustable to accommodate products of different widths.

[0052] Furthermore, the first conveying roller group 33 includes a third active roller 331 and a third passive roller 332, and the second conveying roller group 34 includes a fourth active roller 341 and a fourth passive roller 342; the third active roller 331 and the fourth active roller 341 are arranged parallel to and opposite to each other, and the third passive roller 332 and the fourth passive roller 342 are arranged parallel to and opposite to each other. The fourth passive roller 342 is connected to the cutting blade group 21 to ensure that the cut product flows accurately into the first conveying channel. The first conveying mechanism 30 also includes a first adjusting component 351 and a second adjusting component 352. The first adjusting component 351 is connected to the fourth passive roller 342 to adjust the distance between the fourth passive roller 342 and the cutting blade group 21, thus allowing the first adjusting component 351 to adjust the distance between the first conveying mechanism and the cutting mechanism according to the product size. The second adjusting component 352 is connected to the third passive roller 332 to adjust the distance between the third passive roller 332 and the fourth passive roller 342, thereby adjusting the entrance width of the first conveying channel to accommodate products of different thicknesses. In one embodiment, the first adjusting component 351 and the second adjusting component 352 are arranged in pairs. Specifically, the first adjusting component 351 is located on the outside of the side plate 62 and passes through the side plate 62 to connect with the fourth passive roller 342, and the second adjusting component 352 is located on the outside of the side plate 62 and passes through the side plate 62 to connect with the third passive roller 332.

[0053] In a preferred embodiment, the first conveying mechanism 30 further includes at least one tensioning roller 36, which is disposed between the fourth active roller 341 and the fourth passive roller 342, and is arranged parallel to the fourth active roller 341. The tensioning roller 36 cooperates with the inner side of at least one second conveyor belt 32 to tension the second conveyor belt 32. The tensioning roller 36 is adjustablely connected to the side plate 62, and its inward or outward position can be adjusted by adjusting components such as sliders. In this embodiment, the first conveying mechanism 30 includes two tensioning rollers 36 arranged opposite to each other. One tensioning roller 36 is disposed on the side closer to the second conveyor belt 31, and adjusts the tension to adjust the gap between the first conveyor belt 31 and the second conveyor belt 32, that is, adjust the gap of the first conveying channel to accommodate products of different thicknesses. The other tensioning roller 36 is disposed on the side away from the second conveyor belt 31, and is used to adjust the tension of the second conveyor belt 32.

[0054] like Figure 1 , 2As shown in Figure 6, the folding mechanism 40 is angularly connected to the discharge end of the first conveying mechanism 30. It includes a drive module 41 and a folding plate 42 connected to the drive module 41. The folding plate 42 is angled to the cut product and acts on the cut product to fold it. The second conveying mechanism 50 includes a third conveyor belt group 51, which is angled to the first conveyor belt 31. The third conveyor belt group 51 and the first conveyor belt 31 are located on the same side of the folding plate 42. Preferably, both the third conveyor belt group 51 and the first conveyor belt 31 are located above the folding plate 42. The third conveyor belt group 51, the third drive roller 331, the fourth drive roller 341, and the equipment base plate form a second conveying channel for folding and conveying the folded product. At least a portion of the folding plate 42 inserts into and exits the second conveying channel at a preset frequency. When the folding plate 42 moves towards the second conveying channel and acts perpendicularly on the cut product output from the first conveying channel until it is at least partially embedded in the second conveying channel, the folding plate acts on the cut product to fold it in half to obtain the folded product. In this embodiment, folding is completed below the third active roller 331 and the fourth active roller 341, which can effectively smooth the folded product and prevent the folded product from curling up.

[0055] In a preferred embodiment, the first conveyor belt 31 and the third conveyor belt group 51 are arranged vertically, specifically: the first conveyor belt 31 and the first conveying channel are both vertically arranged, while the folding plate 42 and the third conveyor belt group 51 are both horizontally arranged. When the cut product is output from the lower end of the first channel, the folding plate 42 acts horizontally on a preset part of the cut product and inserts into the second conveying channel. During the insertion process, under the combined action of the folding plate 42, the first conveyor belt 31, and the third conveyor belt group 51, the cut product is folded and conveyed by the third conveyor belt group 51 to the next process, such as a packaging process or a liquid addition process. In a preferred embodiment, the third conveyor belt group 51 includes at least two O-belts mounted on a pair of rollers arranged one in front of the other and arranged according to the number of product conveying columns.

[0056] Furthermore, when the product needs to be packaged, the packaging film is also conveyed in the second conveyor channel, and the folded product is placed on the packaging film and conveyed under the action of the third conveyor belt group 51.

[0057] Furthermore, the folding mechanism 40 also includes a support module, which includes a first support member 43 supporting the drive module 41 and a second support member 44 supporting the folding plate 42. The folding plate 42 moves back and forth on the second support member 44 under the drive of the drive module to achieve folding of the product after cutting.

[0058] The cutting and folding device and production equipment including the device provided in this embodiment include a flattening mechanism, a cutting mechanism, a first conveying mechanism and a folding mechanism. The flattening mechanism flattens the raw material so that the cutting mechanism can cut it. The cooperation between the first conveying mechanism and the folding mechanism realizes the folding of the cut product. The cutting and folding device achieves smooth and reliable production of product cutting and folding by optimizing the structure, and can effectively improve the flatness of the product.
