Abstract
Description
Technical Field
[0001] The invention relates to the technical field of diapers, in particular to a glue spraying and fixing mechanism for an absorbent core of a diaper. Background Art
[0002] Diapers are disposable sanitary products, mainly used by infants, young children and some people with special needs (such as disabled elderly people, etc.), used to absorb and contain urine and feces. They are usually composed of a surface layer, an absorbent core layer, a bottom layer and other parts, and have the characteristics of convenience, hygiene and comfort. The surface layer of diapers is generally made of soft non-woven fabric, which is more comfortable in contact with the skin. It has good air permeability and water permeability, allowing urine to quickly penetrate into the absorbent core layer while reducing irritation to the skin. When the absorbent core is connected to the surface fabric, it is necessary to spray glue on the surface fabric, and then fix the two with glue. When the surface fabric is transported, it needs to be transported by a feed roller. Due to the fabric There may be local uneven shrinkage during the production process. When conveying through rollers, the difference in shrinkage in different parts will cause wrinkles in the fabric. The surface of the fabric in the wrinkled part is uneven. The glue may not be evenly attached to the fabric during spraying, resulting in too much or too little glue in some parts, affecting the overall performance of the diaper. Wrinkles may affect the fit between the absorbent core and the surface fabric, thereby affecting the water absorption and breathability of the diaper. During the fabric conveying process, if the fabric tension is uneven, it will cause the fabric to shift to the side with less tension during conveying. The fabric deviation will cause the glue spraying position to be inconsistent with the designed position, affecting the adhesion effect of the glue and the structural stability of the diaper.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0028] Example 1
[0029] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, and this embodiment provides a diaper absorbent core spraying and fixing mechanism. The diaper absorbent core spraying and fixing mechanism includes a main body component 100, including a spraying mechanism 101, and a first feeding roller 102 and a second feeding roller 103 are arranged below the spraying mechanism 101.
[0030] The glue spraying mechanism 101 is used to spray glue on the cloth so that the water absorbent core can be bonded and fixed to the cloth. The first feeding roller 102 is located directly below the glue spraying mechanism 101. The first feeding roller 102 and the second feeding roller 103 are both used to transport the cloth and fix the cloth, and both are installed on the frame of the overall equipment. Since the installation method and installation position of the two are existing technologies, they are not elaborated in this solution, and the technical personnel in this field can clearly understand the working principle.
[0031] The flattening assembly 200 is arranged above the second feeding roller 103, and includes a rotating roller 201. The rotating roller 201 is located above the second feeding roller 103. A support frame 202 is arranged on the rotating roller 201. The rotating roller 201 is rotatably connected to the support frame 202 through a rotating shaft. A motor 203 is fixed to one side of the support frame 202, and the output shaft of the motor 203 is fixed to the rotating roller 201. A connecting column 204 is fixed to the top of the support frame 202. A fixing sleeve 205 is arranged at the top of the connecting column 204. A rotating rod 206 is inserted in the fixing sleeve 205. A rotating column 207 is fixed at the center of the rotating rod 206. One end of the rotating column 207 is rotatably connected to the glue spraying mechanism 101 through a bearing. A fixing rod 209 is fixed to one side of the glue spraying mechanism 101, and the connecting column 204 is movably connected to the fixing rod 209.
[0032] There are two groups of flattening components 200, which are located on both sides above the second feeding roller 103. The support frame 202 is used to support and install the rotating roller 201, the motor 203 is used to drive the rotating roller 201 to rotate, and the fixing rod 209 is used to support and position the connecting column 204 to prevent it from offset during movement.
[0033] When the cloth passes over the top of the second feeding roller 103, the rotating roller 201 will contact the top of the cloth and apply a slight downward pressure. As the rotating roller 201 rotates, the rotating roller 201 will pull the edges of the cloth on both sides to both sides, so that the cloth can be stretched into a flat state, so that the glue can be evenly sprayed on the top of the cloth.
[0034] When the movement of the cloth deviates, the rotating rod 206 will tilt in the opposite direction of the cloth deviation, and drive the fixed sleeve 205 in this direction to move downward, drive the connecting column 204 and the support frame 202 to move downward through the fixed sleeve 205, and drive the rotating roller 201 downward through the support frame 202 to contact the cloth more closely, thereby increasing the friction with the cloth. At this time, the rotating roller 201 on the other side will move upward and reduce the friction with the cloth. At this time, the friction between the rotating roller 201 on one side and the cloth increases, and the friction between the rotating roller 201 on one side and the cloth decreases. The cloth can be driven to move through the rotating roller 201, so that the cloth moves to a position opposite to the tilting direction, so that the position of the cloth can be corrected, so that the glue can be sprayed at the correct position of the cloth. After the cloth is corrected, the rotating rollers 201 on both sides will restore the friction with the cloth, so that the cloth can continue to be flattened to avoid excessive movement of the cloth.
[0035] The positioning assembly 300 is arranged on the first feed roller 102, and includes a support plate 301, the support plate 301 is fixed to the outside of the first feed roller 102, a spring 302 is fixed to one side of the support plate 301, and a positioning sleeve 303 is fixed to the other end of the spring 302. The positioning sleeve 303 is sleeved on the outside of the first feed roller 102 and is movably connected to the first feed roller 102.
[0036] There are two groups of positioning components 300, which are located at the two ends of the outer side of the first feed roller 102 respectively. The support plate 301 is used to support and fix the spring 302. The spring 302 is used to apply elastic force to the positioning sleeve 303. The positioning sleeve 303 is used to support and position the cloth on the top of the first feed roller 102 to prevent the cloth from shifting during movement.
[0037] During the conveying process, the cloth will be stretched into a taut state by the tensioning mechanism. In this state, the side of the cloth has a certain hardness. If the cloth is offset under external force, the cloth will push the positioning sleeve 303 to move.
[0038] Example 2
[0039] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.
[0040] Specifically, it also includes a transmission component 400, which is arranged on the glue spraying mechanism 101, including a connecting rod 401, the connecting rod 401 is fixed to the top of the rotating column 207, a movable sleeve 402 is sleeved on the outer side of the connecting rod 401, one side of the movable sleeve 402 is rotatably connected to a fixed column 403 through a bearing, and a movable rod 404 is fixed to one end of the fixed column 403.
[0041] There are two groups of transmission components 400, corresponding to the two groups of flattening components 200 and positioning components 300 respectively. When the movable rod 404 moves, it will drive the movable sleeve 402 to move through the fixed column 403, and drive the connecting rod 401 and the rotating column 207 to rotate through the movable sleeve 402, so that the rotating rod 206 can be driven to rotate through the rotating column 207.
[0042] Specifically, a mounting frame 405 is fixed on one side of the glue spraying mechanism 101 , and an extrusion rod 406 is rotatably connected to the center of the mounting frame 405 via a rotating shaft. A push rod 407 is provided on one side of the positioning sleeve 303 , and one side of the push rod 407 is in contact with the extrusion rod 406 .
[0043] When the positioning sleeve 303 is squeezed by the cloth and moves, it will push the push rod 407 to move, and push the bottom end of the squeezing rod 406 to rotate through the push rod 407. At this time, the top end of the squeezing rod 406 will push the movable rod 404 to move.
[0044] Specifically, a support rod 408 is fixed at the bottom of the glue spraying mechanism 101 , a stabilizing rod 409 is fixed at the bottom of the support rod 408 , and the stabilizing rod 409 is movably connected to the push rod 407 to support and position the push rod 407 .
[0045] Specifically, one side of the upper side of the squeezing rod 406 contacts with the movable rod 404 and cooperates with the movable rod 404 .
[0046] Specifically, the rotating roller 201 and the support frame 202 are both inclined, and the support frame 202 is U-shaped.
[0047] The two rotating rollers 201 are arranged in an eight-shaped shape. Through this design, the rotating rollers 201 can stretch the cloth to both sides while providing forward force to the cloth, thereby avoiding affecting the normal movement of the cloth during the process of pulling the rope to both sides.
[0048] Example 3
[0049] Reference Figure 1-Figure 6, which is the third embodiment of the present invention, and is based on the first two embodiments.
[0050] Specifically, the top of the connecting column 204 is rotatably connected to a connecting block 208 via a rotating shaft, the top of the connecting block 208 is fixed to the fixing sleeve 205 , and the fixing sleeve 205 is hinged to the connecting column 204 via the connecting block 208 .
[0051] Specifically, a stabilizing frame 410 is fixed on the top of the glue spraying mechanism 101 , and the movable rod 404 is movably connected to the inside of the stabilizing frame 410 . The stabilizing frame 410 is used to guide and position the movable rod 404 .
[0052] Specifically, a glue spraying head 104 is disposed at the bottom of the glue spraying mechanism 101 .
[0053] The glue is sprayed evenly on the cloth through the glue spraying head 104 .
[0054] Specifically, the extrusion rod 406 is inclined.
[0055] When in use, when the cloth is fixed to the absorbent core, glue is sprayed on the cloth through the glue spraying mechanism 101, and the cloth is conveyed through the first feeding roller 102 and the second feeding roller 103. When the cloth passes over the top of the second feeding roller 103, the rotating roller 201 will contact the top of the cloth and apply a slight pressure downward. As the rotating roller 201 rotates, the rotating roller 201 will pull the edges of the two sides of the cloth to both sides, so that the cloth can be stretched into a flat state, so that the glue can be evenly sprayed on the top of the cloth.
[0056] During the conveying process, the cloth will be stretched into a taut state by the tensioning mechanism. In this state, the side of the cloth has a certain hardness. If the cloth is offset under external force, the cloth will push the positioning sleeve 303 to move. When the positioning sleeve 303 is squeezed and moved by the cloth, it will push the push rod 407 to move, and the push rod 407 will push the bottom end of the squeezing rod 406 to rotate. At this time, the top of the squeezing rod 406 will push the movable rod 404 to move.
[0057] When the movable rod 404 moves, the movable sleeve 402 is driven to move through the fixed column 403 , and the connecting rod 401 and the rotating column 207 are driven to rotate through the movable sleeve 402 , so that the rotating rod 206 can be driven to rotate through the rotating column 207 .
[0058] At this time, the rotating rod 206 will tilt in the opposite direction of the fabric deviation, and drive the fixed sleeve 205 in this direction to move downward, drive the connecting column 204 and the support frame 202 to move downward through the fixed sleeve 205, and drive the rotating roller 201 downward through the support frame 202 to contact the fabric more closely, thereby increasing the friction with the fabric. At this time, the rotating roller 201 on the other side will move upward and reduce the friction with the fabric. At this time, the friction between the rotating roller 201 on one side and the fabric increases, and the friction between the rotating roller 201 on one side and the fabric decreases, so that the fabric can be driven to move through the rotating roller 201, so that the fabric moves to a position opposite to the tilting direction, so that the position of the fabric can be corrected, so that the glue can be sprayed at the correct position of the fabric. When the fabric correction is completed, the rotating rollers 201 on both sides will restore the friction with the fabric, so that the fabric can continue to be flattened to avoid excessive movement of the fabric.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
