[0017] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] Example 1

[0019] Please see Figures 1 to 7 The present invention preferably provides the following technical solution: a conveying device for packaging sanitary napkins, comprising: a frame 111; a first inclined belt mechanism and a second inclined belt mechanism disposed on and below the frame 111, wherein a conveying channel for transporting single sanitary napkins can be formed between the first inclined belt mechanism and the second inclined belt mechanism; and a horizontal belt mechanism disposed at the front end of the first inclined belt mechanism and the second inclined belt mechanism, wherein the convergence area of ​​the first inclined belt mechanism, the second inclined belt mechanism and the horizontal belt mechanism can be used for palletizing and conveying sanitary napkins; and further comprising a batch pushing mechanism disposed at the front end of the horizontal belt mechanism for facilitating the combination packaging of sanitary napkins.

[0020] In this embodiment, see Figure 1 , 2 As shown in Figures 3, 6, and 7, the frame 111 is equipped with a first inclined belt mechanism, a second inclined belt mechanism, and a horizontal belt mechanism at its upper, lower, and front ends, respectively. The first and second inclined belt mechanisms can form a material conveying channel for transporting single sanitary napkins. Because sanitary napkins are soft and thin, they are prone to curling, folding, or shifting during transport. The inclined belt mechanisms can form a stable and narrow material conveying channel to gently hold both sides of a single sanitary napkin, ensuring that it maintains a flat posture and predetermined direction during transport. This effectively prevents jamming or deformation caused by slipping or rolling. In addition, the inclined channel naturally guides the sanitary napkin to the center position, providing a precise positioning basis for the subsequent stacking process. This ensures that each sanitary napkin can enter the stacking area in almost the same position and posture, which is a key prerequisite for achieving neat stacking. The convergence area of ​​the first inclined belt mechanism, the second inclined belt mechanism, and the horizontal belt mechanism is as follows: Figure 6 , 7 As shown, the convergence design of inclined and horizontal conveying makes the transition of sanitary napkins from being clamped to being released and laid flat very natural and smooth. The sanitary napkins are "delivered" to the horizontal belt at the end of the inclined belt, avoiding displacement, skewing or collision caused by direct falling, and ensuring the neatness of the stacking. In addition, this convergence area is a carefully designed "transfer area". After the first sanitary napkin is transported to the predetermined position by the horizontal belt, it stops, and the subsequent sanitary napkins are continuously delivered and stacked horizontally one by one. This centralized and orderly stacking method greatly improves the efficiency of packaging and conveying. The batch pushing mechanism installed in front of the horizontal belt conveyor can push the stacked sanitary napkins out of the horizontal belt as a whole according to the preset quantity (such as 5 pieces, 10 pieces or the capacity of a packaging bag) and into the next packaging stage (such as bagging machine, wrapping machine). This realizes the automated connection from single-piece conveying to group packaging. This group pushing can be perfectly synchronized with the previous palletizing rhythm and the subsequent packaging rhythm to form a continuous and stable production rhythm, avoiding the speed bottleneck of manual sorting and feeding, and significantly improving the overall packaging efficiency.

[0021] Example 2

[0022] In another embodiment of this utility model, the first inclined belt mechanism includes a first mounting plate 117 and a second mounting plate 118 fixed on both sides of the frame 111, and a third mounting plate 119 fixed to the first mounting plate 117 and the second mounting plate 118; and a first transmission wheel 120 rotatably mounted on the middle of the second mounting plate 118 and the third mounting plate 119 respectively; it also includes a first adjusting wheel assembly 122 and a second adjusting wheel assembly 121 respectively disposed on both sides of the second mounting plate 118, and a first transmission belt 123 is sleeved on the outer periphery of the first adjusting wheel assembly 122, the second adjusting wheel assembly 121 and the two first transmission wheels 120; a first motor 125 is also disposed on the outer side of the second mounting plate 118, and the output shaft of the first motor 125 passes through a first mounting hole opened on the second mounting plate 118 and is fixedly connected to the first transmission wheel 120 on the second mounting plate 118.

[0023] like Figure 2 , 6 As shown in Figure 7, two first transmission wheels 120 are rotatably mounted on the middle of the second assembly plate 118 and the end of the third assembly plate 119, respectively. The first adjusting wheel assembly 122 and the second adjusting wheel assembly 121 are respectively disposed on both sides of the second assembly plate 118, such that the first transmission belt 123, which is sleeved on the outer periphery of the first adjusting wheel assembly 122, the second adjusting wheel assembly 121, and the two first transmission wheels 120, forms a triangular shape. Because the first adjusting wheel assembly 122... Figure 6 The first drive belt 123 is positioned at the end of the first drive belt 123, while the second adjusting wheel assembly 121 is positioned in the middle of the first drive belt 123. Therefore, by adjusting the first adjusting wheel assembly 122 and the second adjusting wheel assembly 121, the transverse diameter and longitudinal diameter of the first drive belt 123 can be adjusted, thereby realizing the gap adjustment of the material conveying channel between the first and second inclined belt mechanisms to adapt to the conveying of sanitary napkins of different thicknesses, and at the same time adjusting the tension of the first drive belt 123.

[0024] Furthermore, the first adjusting wheel assembly 122 includes two extension plates 1221 fixed to one side of the second mounting plate 118, each extension plate 1221 having a first sliding groove 1222; and a first slider 1223 disposed within the first sliding groove 1222, wherein the two first sliders 1223 are rotatably mounted with a first adjusting wheel body 1224 via a first rotating shaft disposed therebetween, the first adjusting wheel body 1224 contacting the first transmission belt 123; and also includes a first locking component disposed on one of the extension plates 1221 for the first slider 1222... The position of 23 is locked; further, the first locking component includes a locking strip 1225 fixed to one side of the extension plate 1221, the locking strip 1225 having a first locking groove; and an extension block 1226 fixed to the corresponding first slider 1223, the extension block 1226 extending toward the locking strip 1225 and having a first through hole; it also includes a bolt 1227 disposed in the first through hole, when the bolt 1227 passes through the first through hole and is threadedly connected to the first locking groove where the locking strip 1225 is located, it is used to lock the position of the first slider 1223.

[0025] Since there are two extension plates 1221, and the first adjusting wheel 1224 which contacts the bottom of the first transmission belt 123 is rotatably mounted between the two first sliders 1223, and the two first sliders 1223 are respectively housed inside the first slide grooves 1222 opened on the two extension plates 1221, the gap between the first transmission belt 123 and the second adjusting wheel assembly 121 can be adjusted when the position of the first slider 1223 in the first slide groove 1222 is adjusted. The position adjustment of the first slider 1223 can be as follows: Figure 5 As shown, since an extension block 1226 is fixed on one of the first sliders 1223, a bolt 1227 is provided in the first through hole on it. When it is necessary to adjust the position of the first slider 1223, the bolt 1227 first disengages from the first locking groove of the locking strip 1225. At this time, the first slider 1223 and the first adjusting wheel 1224 can move freely. When the first adjusting wheel 1224 is adjusted to a suitable position, the bolt 1227 passes through the first through hole and is fixed with the first locking groove on the locking strip 1225, thus fixing the position of the first slider 1223 and the first adjusting wheel 1224.

[0026] Furthermore, the second adjusting wheel assembly 121 includes two mounting slots 1211 formed on the side wall of the second mounting plate 118, each mounting slot 1211 having a mounting block 1212 and a mounting strip 1213 fixed to the mounting block 1212; a second sliding groove 1214 formed inside the mounting strip 1213, the second sliding groove 1214 having a second slider 1215; and a second adjusting wheel body 1216 rotatably mounted to the two second sliders 1215 via a second rotating shaft disposed between the two second sliders 1215, the second adjusting wheel body 1216 contacting the first transmission belt 123; and also includes a second locking component disposed on one of the mounting strips 1213 and having the same structure as the first locking component.

[0027] like Figure 3 , 4 As shown, the second adjusting wheel assembly 121 and the first adjusting wheel assembly 122 have basically the same structure and operation, so they will not be described again here. For specific operation, please refer to the explanation of the first adjusting wheel assembly 122 above.

[0028] Example 3

[0029] In another embodiment of this utility model, the second inclined belt mechanism includes a second transmission wheel 112, a third transmission wheel 113, and two fourth transmission wheels. The second transmission wheel 112 and the third transmission wheel 113 are rotatably mounted on the upper and lower sides of the frame 111, and the two fourth transmission wheels are rotatably mounted on the upper and lower parts of the middle of the frame 111. A second transmission belt 116 is looped around the second transmission wheel 112, the third transmission wheel 113, and the two fourth transmission wheels. The mechanism also includes a second motor 124 disposed on the outside of the frame 111, and the output shaft of the second motor 124 passes through a second mounting shaft opened in the side wall of the frame 111 and is fixed to the third transmission wheel 113.

[0030] like Figure 2 , 6 As shown in Figure 7, since the second transmission wheel 112, the third transmission wheel 113, and the two fourth transmission wheels are connected by a second transmission belt 116 fitted on them, when the second motor 124 drives the third transmission wheel 113 and the first motor 125 drives the first transmission wheel 120, as shown in Figure 7, the transmission is as follows: Figure 6 The clockwise rotating first transmission belt 123 and the counterclockwise rotating second transmission belt 116 can transport a single sanitary napkin to the horizontal belt mechanism.

[0031] Example 4

[0032] As another embodiment of the present invention, an elastic wheel assembly is also provided on the outer periphery of the third transmission wheel 113 for adaptive adjustment of the tension of the second transmission belt 116; the elastic wheel assembly includes a roller body 114 fixed on the outer periphery of the third transmission wheel 113; and a spring piece 115 annularly fixed on the outer periphery of the roller body 114, and the spring piece 115 is in contact with the second transmission belt 116.

[0033] In this embodiment, because the spring piece 115 arranged in a ring around the outer periphery of the roller 114 contacts the second transmission belt 116, when the second transmission belt 116 is conveying sanitary napkins, the second transmission belt 116 can have a certain elasticity or floating space due to the elastic action of the spring piece 115. Combined with the change in shape of the first transmission belt 123, it can adapt to sanitary napkins of different models and thicknesses, such as daytime, nighttime, and panty liners, to achieve "multi-purpose use on one line". This improves the flexibility of the production line, eliminates the need to frequently change equipment for each product, and the elasticity can further improve the stability of the sanitary napkin clamping.

[0034] Example 5

[0035] As another embodiment of this utility model, the horizontal belt mechanism includes a base frame 211 fixed to the front end of the frame 111, and transmission rollers 212 are rotatably mounted on both the base frame 211 and the frame 111; and a third transmission belt 213 sleeved on the outer periphery of the two transmission rollers 212; it also includes a third motor 221 disposed on the outside of the base frame 211, and the output end of the third motor 221 passes through a third mounting hole opened in the side wall of the base frame 211 and is fixedly connected to the corresponding transmission roller 212; furthermore, a connecting plate 214 is provided at the convergence position of the first transmission belt 123, the second transmission belt 116 and the third transmission belt 213 on the frame 111.

[0036] like Figure 2 , 6 As shown in Figure 7, one end of the third drive belt 213 extends into the frame 111 and connects to the bottom end of the connecting plate 214, while the top end of the connecting plate 214 connects to the outlet of the conveying channel. Therefore, when the sanitary napkin is conveyed to the surface of the third drive belt 213, as shown in Figure 7, it is like... Figure 6 The counterclockwise rotating third drive belt 213 can transport sanitary napkins forward. Due to the limiting effect of the first drive belt 123, the sanitary napkins can be stacked and transported in an orderly array in the convergence area of ​​the first drive belt 123, the second drive belt 116 and the third drive belt 213.

[0037] Example 6

[0038] As another embodiment of the present invention, the batch feeding mechanism includes two through slots 218 opened at the front end of the base frame 211, wherein the base frame 211 is provided with a push plate 217 with a Z-shaped cross section at the position of one of the through slots 218, and a receiving platform 220 is fixed on the outside of the other through slot 218; and an L-shaped frame 215 is fixed on the side of the base frame 211 near the push plate 217, and a plurality of cylinders 216 are assembled between the L-shaped frame 215 and the push plate 217.

[0039] This implementation example Figure 1 As shown, an L-shaped frame 215 and a receiving platform 220 are respectively provided on both sides of the base frame 211. A cylinder 216 is provided on the L-shaped frame 215. A push plate 217 is fixed at the output end of the cylinder 216. The push plate 217 can span the two through slots 218 of the base frame 211. Since the cross-section of the push plate 217 is Z-shaped, when the far end of the push plate 217 blocks the base frame 211, the sanitary napkin can enter the interior of the push plate 217. Then, when the cylinder 216 extends, the push plate 217 can push several sanitary napkins inside it into the receiving platform 220. At this time, the near end of the push plate 217 blocks the base frame 211, thereby realizing the combined pushing process of the sanitary napkin.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0041] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
