Description

Technical Field

[0001] The present invention relates to the technical field of material surface treatment, in particular to a sanitary napkin production surface spray treatment machine and a spraying method. Background Art

[0002] The surface spraying machine for sanitary napkin production is a kind of equipment specially used in the production process of sanitary napkins. Its main function is to accurately spray hot melt adhesives such as adhesives on specific surface parts of sanitary napkins. Sanitary napkins are generally composed of multiple layers of materials, including the surface layer, the absorbent core layer and the bottom layer. During production, these different material layers need to be firmly combined together. At this time, a surface spraying machine is needed. When using hot melt adhesive, the block hot melt adhesive is usually crushed, and then heated to form a liquid for spraying. The block hot melt adhesive is first crushed into smaller particles or fragments because the block hot melt adhesive is larger in volume. Direct heating has a low melting efficiency and may result in uneven heating. The crushed hot melt adhesive has a larger surface area and can absorb heat faster and more evenly when heated, thereby converting into liquid more efficiently. However, the crushing frequency cannot be adjusted according to the size of the hot melt adhesive block during crushing. When crushing smaller hot melt adhesives, they will be over-crushed. When the hot melt adhesive is over-crushed into very fine particles, it may become too thin and too fluid. The overly thin hot melt adhesive cannot provide sufficient bonding strength to maintain the structural integrity of the sanitary napkin. During use, the layers of material of the sanitary napkin may be delaminated. Summary of the invention

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] 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.

[0035] Example 1

[0036] Reference Figure 2 to Figure 11 , which is the first embodiment of the present invention, and this embodiment provides a sanitary napkin production surface spraying treatment machine and spraying method. The sanitary napkin production surface spraying treatment machine and spraying method include a crushing component 200, an adjustment component 300 and a main body component 100.

[0037] The crushing assembly 200 includes a crushing part 201, including a feed barrel 201a, a conical block 201b, a crushing cover 201c, a rotating disk 201d, a driving rod 201e, a rotating wheel 201f, a driving wheel 201g and a driving column 201h. The conical block 201b is movably connected to the inside of the feed barrel 201a, the crushing cover 201c is sleeved on the outside of the conical block 201b, the crushing cover 201c is fixed to the inner wall of the feed barrel 201a, the rotating disk 201d is arranged on one side of the feed barrel 201a, the driving rod 201e is located on one side of the rotating disk 201d, the rotating wheel 201f is fixed to one side of the driving rod 201e, the driving wheel 201g is arranged on one side of the rotating wheel 201f, and the driving column 201h is plugged into one side of the driving wheel 201g.

[0038] The conical block 201b is movably connected to the inner wall of the feed barrel 201a through a ball joint, and a driving frame corresponding to the driving rod 201e is provided on the rotating disk 201d. When the driving rod 201e rotates into the driving frame, it can be squeezed to make the rotating disk 201d rotate. When the driving rod 201e rotates to separate from the driving frame, the rotating disk 201d will stop rotating. In this reciprocating manner, the rotating disk 201d can be rotated slowly.

[0039] By placing the hot melt adhesive block in the feed barrel 201a, and then rotating the driving rod 201e to drive the rotating wheel 201f to rotate, teeth are provided on the driving wheel 201g and the rotating wheel 201f, and the two are engaged. The rotation of the driving wheel 201g will drive the rotating wheel 201f to rotate, and the rotation of the rotating wheel 201f drives the driving rod 201e to rotate. The rotation of the driving rod 201e can drive the rotating disk 201d to rotate, and the rotation of the rotating disk 201d drives the conical block 201b to move in the crushing cover 201c. When the hot melt adhesive block falls to one side of the crushing cover 201c, the hot melt adhesive block can be crushed by moving the conical block 201b. The inner wall of the crushing cover 201c is provided with a bump to improve the crushing efficiency.

[0040] The adjusting assembly 300 is arranged on the rotating disk 201d, and includes a rotating shell 301a, a driving shell 301b, a moving disk 301c, a moving frame 301d, a sloped block 301e, an extrusion block 301f and a pressing rod 301g. The rotating shell 301a is fixed to one side of the rotating disk 201d, the driving shell 301b is located on one side of the rotating shell 301a, the driving shell 301b is sleeved on the outside of the driving rod 201e, the moving disk 301c is sleeved on the outside of the driving rod 201e, the moving frame 301d is sleeved on the outside of the moving disk 301c, the moving frame 301d and the moving disk 301c are movably connected, the sloped block 301e is fixed to one end of the moving frame 301d, the extrusion block 301f is arranged on the top of the sloped block 301e, and the pressing rod 301g is fixed to the top of the extrusion block 301f.

[0041] An extrusion groove corresponding to the driving shell 301b is provided in the rotating shell 301a, and a driving tooth corresponding to the extrusion groove is provided on the driving shell 301b. When it is necessary to engage the rotating shell 301a with the driving shell 301b to increase the rotation speed of the rotating disk 201d, the lower pressure rod 301g is moved, and the movement of the lower pressure rod 301g will drive the extrusion block 301f to squeeze the inclined block 301e. At this time, the inclined block 301e can drive the moving frame 301d to move, and the movement of the moving frame 301d will drive the moving disk 301c to move, and the moving disk 301c will drive the driving column 201h to move. When the driving column 201h moves, it will drive the rotating wheel 201f and the driving wheel 201g to separate. At this time, the driving wheel 201g will not drive the rotating wheel 201f to rotate.

[0042] When the driving column 201h moves, it will drive the rotating shell 301a to engage with the driving shell 301b. When the driving column 201h rotates, it can directly drive the rotating disk 201d to rotate. There is no need to rotate the driving rod 201e into the driving frame to squeeze it, so that the rotating disk 201d can rotate slowly.

[0043] Example 2

[0044] Reference Figure 2 to Figure 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0045] Specifically, the crushing assembly 200 also includes a movable part 202, which is arranged on the conical block 201b. An eccentric column 202a is fixed to the bottom of the conical block 201b. A rotating sleeve 202b is sleeved on the outer side of the eccentric column 202a. The rotating sleeve 202b and the eccentric column 202a are movably connected. A bevel cover 202c is sleeved on the outer side of the rotating sleeve 202b. The bevel cover 202c and the rotating sleeve 202b are rotatably connected through a bearing. A first bevel gear 202d is sleeved on the outer side of the rotating sleeve 202b. A second bevel gear 202e is arranged on one side of the first bevel gear 202d. The first bevel gear 202d and the second bevel gear 202e are meshed. A rotating column 202f is fixed on one side of the second bevel gear 202e, and the rotating column 202f is fixed to one side of the rotating disk 201d.

[0046] The rotating column 202f is inserted into one side of the mixing box 101, and the rotating column 202f is rotatably connected to the mixing box 101 through a rotating shaft. When the rotating disk 201d rotates, the rotating column 202f is driven to rotate, and the rotation of the rotating column 202f drives the second bevel gear 202e to rotate, and the second bevel gear 202e drives the first bevel gear 202d to rotate. The rotation of the first bevel gear 202d drives the rotating sleeve 202b to rotate, and the rotating sleeve 202b drives the eccentric column 202a to move. When the eccentric column 202a moves, it can drive the conical block 201b to move, so that the hot melt adhesive block can be crushed. The bevel cover 202c is fixed to the inner wall of the mixing box 101. The setting of the bevel cover 202c can support the rotating sleeve 202b, and the crushed hot melt adhesive block can be guided so that it can be moved into the mixing box 101 for the next step of processing.

[0047] Specifically, a positioning block 202g is provided on one side of the rotating wheel 201f, the positioning block 202g is rotatably connected to the rotating wheel 201f through a rotating shaft, a protective frame 202h is sleeved on the outer side of the positioning block 202g, the positioning block 202g is sleeved on the outer side of the driving column 201h, and the positioning block 202g and the driving column 201h are movably connected.

[0048] The positioning block 202g is used to support the rotating wheel 201f and the driving column 201h to prevent the two from shifting. The setting of the protective frame 202h can protect the rotating shell 301a and the driving shell 301b to prevent damage caused by being hit by external debris, and can support the positioning block 202g to prevent the positioning block 202g from shifting.

[0049] Specifically, an output shaft 202i is sleeved on the outer side of the driving column 201h, and the output shaft 202i and the driving column 201h are movably connected. A motor 202j is fixed to one side of the output shaft 202i, and the motor 202j is fixed to one side of the protective frame 202h.

[0050] A card block is provided at one end of the driving column 201h, and a card slot is provided in the output shaft 202i. The card block slides in the card slot. By starting the motor 202j, the output shaft 202i is driven to rotate. When the output shaft 202i rotates, the card block is driven to rotate. The rotation of the card block squeezes the card slot, thereby causing the driving column 201h to rotate.

[0051] Specifically, the adjustment component 300 also includes a moving part 302, which is arranged on the rotating disk 201d, a first spring 302a is fixed in the rotating shell 301a, a driving rod 201e is inserted into one side of the rotating shell 301a, the driving rod 201e and the rotating shell 301a are movably connected, a first support rod 302b is inserted into one side of the moving frame 301d, the first support rod 302b and the moving frame 301d are movably connected, the first support rod 302b is fixed to the inner wall of the protective frame 202h, a second support rod 302c is inserted into the top of the lower pressure rod 301g, the second support rod 302c is movably connected to the lower pressure rod 301g, and the second support rod 302c is fixed to the inner wall of the protective frame 202h.

[0052] When the rotating shell 301a is engaged with the driving shell 301b, an extrusion force can be applied to the first spring 302a. When the rotating shell 301a and the driving shell 301b need to be separated, the two can be separated by the rebound force of the first spring 302a. When the moving frame 301d moves, it moves on the first support rod 302b. The first support rod 302b can be used to support the moving frame 301d to prevent the moving frame 301d from shifting during movement. The second support rod 302c can be used to support the downward pressure rod 301g to prevent the downward pressure rod 301g from shifting.

[0053] Specifically, a lower pressing block 302d is fixed at one end of the lower pressing rod 301g, a lower pressing strip 302e is arranged on the top of the lower pressing block 302d, the lower pressing block 302d and the lower pressing strip 302e are hinged, a rotating block 302f is arranged at one end of the lower pressing strip 302e, the lower pressing strip 302e and the rotating block 302f are hinged, and the rotating block 302f and the inner wall of the protective frame 202h are hinged.

[0054] By rotating the rotating block 302f, the lower pressing bar 302e can be squeezed to rotate. When the lower pressing bar 302e rotates, it can move the lower pressing block 302d. When the lower pressing block 302d moves, it can drive the lower pressing rod 301g to move.

[0055] Example 3

[0056] Reference Figures 1 to 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0057] Specifically, a handle 302g is fixed on one side of the rotating block 302f, a positioning rod 302h is inserted on the top of the pressing block 302d, the pressing block 302d and the positioning rod 302h are movably connected, the positioning rod 302h is fixed to the inner wall of the protective frame 202h, and a second spring 302i is fixed to the bottom of the pressing block 302d, and the second spring 302i is fixed to the bottom of the pressing block 302d.

[0058] The setting of the handle 302g is convenient for the user to rotate the rotating block 302f. The positioning rod 302h is used to support the lower pressing block 302d to prevent the lower pressing block 302d from shifting. When the lower pressing block 302d is moved, a squeezing force can be applied to the second spring 302i. When the lower pressing block 302d needs to be returned to its original position, the rebound force of the second spring 302i can drive the lower pressing block 302d to return to its original position.

[0059] Specifically, the adjustment component 300 also includes a limit member 303, which is arranged on the protective frame 202h. A limit block 303a is arranged on one side of the protective frame 202h. A connecting frame 303b is sleeved on the outer side of the limit block 303a. The limit block 303a and the connecting frame 303b are movably connected. A pull rod 303c is fixed on one side of the limit block 303a. The pull rod 303c is inserted into the inner wall of the connecting frame 303b. The pull rod 303c and the connecting frame 303b are movably connected. A third spring 303d is fixed on the inner wall of the connecting frame 303b. The third spring 303d is fixed to one side of the limit block 303a.

[0060] The limit block 303a is set as an inclined surface. After the handle 302g is rotated to rotate the rotating block 302f, in order to prevent the rebound force of the second spring 302i from driving the pressing block 302d to return to its original position, the handle 302g is moved to one side of the limit block 303a to squeeze it. At this time, the limit block 303a can be moved into the connecting frame 303b. When the limit block 303a moves into the connecting frame 303b, it can apply a squeezing force on the third spring 303d. When the handle 302g moves to the other side of the limit block 303a, the rebound force of the third spring 303d can make the limit block 303a return to its original position, thereby limiting the handle 302g and preventing the handle 302g from rebounding.

[0061] When it is necessary to release the limit on the handle 302g, the pull rod 303c is pulled, and the pull rod 303c drives the limit block 303a to move into the connecting frame 303b. At this time, the handle 302g can be released. After releasing, the pull rod 303c is released, and the rebound force of the third spring 303d drives the limit block 303a to return to its original position for next use. The connecting frame 303b is fixed to one side of the protective frame 202h. The setting of the connecting frame 303b can support the limit block 303a to prevent the limit block 303a from shifting.

[0062] Specifically, it also includes a main body component 100, which is arranged on the feed barrel 201a, including a mixing box 101, a mixing rod 102, a first bevel gear 103, a second bevel gear 104, a movable column 105, a pulley 106, a belt 107, a melting cylinder 108 and a sprayer 109. The mixing box 101 is fixed at the bottom of the feed barrel 201a, the mixing rod 102 is arranged in the mixing box 101, the first bevel gear 103 is fixed at the bottom of the mixing rod 102, the second bevel gear 104 is arranged on one side of the first bevel gear 103, the first bevel gear 103 and the second bevel gear 104 are meshed, the movable column 105 is fixed at one side of the second bevel gear 104, the pulley 106 is fixed at one end of the movable column 105, the belt 107 is sleeved on the outside of the pulley 106, the melting cylinder 108 is located at the bottom of the mixing box 101, and the sprayer 109 is arranged at the bottom of the melting cylinder 108.

[0063] After the crushed hot melt adhesive block is moved into the mixing box 101, the rotation of the motor 202j will drive the pulley 106 to rotate. There are two pulleys 106, which are fixed to the outer side of the motor 202j and one end of the movable column 105 respectively. The rotation of the pulley 106 drives the belt 107 to rotate. The rotation of the belt 107 drives the other pulley 106 to rotate. The rotation of the pulley 106 drives the movable column 105 to rotate. The rotation of the movable column 105 drives the second bevel gear 104 to rotate. The second bevel gear 10 The first bevel gear 103 is driven to rotate, and the rotation of the first bevel gear 103 drives the stirring rod 102 to rotate. The stirring rod 102 can stir the hot melt adhesive in the stirring box 101. The stirring of the stirring rod 102 can make particles of different sizes fully mixed, and then the hot melt adhesive is heated by the melting cylinder 108 to melt it. A conveyor belt is set on the sprayer 109 for conveying sanitary napkins. The setting of the sprayer 109 can spray the sanitary napkins being conveyed.

[0064] Specifically, first, the hot melt adhesive is placed in the feed barrel 201a, and then the hot melt adhesive is crushed by using the conical block 201b, and the crushed hot melt adhesive naturally falls into the mixing box 101;

[0065] A stirring rod 102 is provided in the stirring box 101, which can fully stir the crushed hot melt adhesive, and the stirred hot melt adhesive will continue to fall into the melting tank 108;

[0066] The melting cylinder 108 heats the hot melt adhesive to turn it into a viscous liquid state, and then sprays the heated hot melt adhesive on the sanitary napkin being transported on the sprayer 109. Finally, the sprayed sanitary napkin is transported to the next location for further processing.

[0067] First, the hot melt adhesive is placed in the feed barrel 201a to provide a reserve of raw materials for subsequent processing. The hot melt adhesive is crushed using the conical block 201b, and the crushed hot melt adhesive naturally falls into the mixing box 101, turning large pieces of hot melt adhesive into smaller particles, increasing the surface area of ​​the hot melt adhesive, and facilitating the subsequent heating and stirring process, so that it can be heated and mixed more quickly and evenly. The stirring rod 102 in the mixing box 101 fully stirs the crushed hot melt adhesive to ensure that the additives are evenly distributed in the hot melt adhesive, improve the overall performance consistency of the hot melt adhesive, and promote heat transfer, accelerate the melting speed of the hot melt adhesive, and avoid burning caused by local overheating. The hot melt adhesive is stirred and will continue to fall into the melting cylinder 108, which will heat the hot melt adhesive to turn it into a viscous liquid state. The heated and melted hot melt adhesive will have good fluidity and adhesion, and will be ready for subsequent spraying operations. The heated hot melt adhesive will be sprayed on the sanitary napkin being transported on the sprayer 109. Through precise spraying operations, the hot melt adhesive can be evenly coated on specific parts of the sanitary napkin, thereby achieving functions such as bonding of various layers of materials and making leak-proof edges, thereby improving the quality and performance of the sanitary napkin. Finally, the sprayed sanitary napkin will be transported to the next location for further processing.

[0068] When in use, put the hot melt adhesive block into the feed barrel 201a, and then start the motor 202j, the motor 202j will drive the output shaft 202i to rotate, the rotation of the output shaft 202i will drive the driving column 201h to rotate, the rotation of the driving column 201h will drive the driving wheel 201g to rotate, the driving wheel 201g will drive the rotating wheel 201f to rotate, the rotating wheel 201f will drive the driving rod 201e to rotate, when the driving rod 201e rotates into the driving frame, it can be squeezed, so that the rotating disk 201d can be rotated, when the driving rod 201e rotates to separate from the driving frame, the rotating disk 201d will stop rotating, and so on. The rotation of the rotating disk 201d can cause the rotating column 202f to rotate slowly, and the rotation of the rotating disk 201d can drive the rotating column 202f to rotate. The rotation of the rotating column 202f can drive the second bevel gear 202e to rotate, and the second bevel gear 202e drives the first bevel gear 202d to rotate. The rotation of the first bevel gear 202d can drive the rotating sleeve 202b to rotate, and the rotating sleeve 202b drives the eccentric column 202a to move. When the eccentric column 202a moves, it can drive the conical block 201b to move, so that the hot melt adhesive block can be crushed. The crushed hot melt adhesive will fall into the mixing box 101 through the guidance of the bevel cover 202c.

[0069] When the output shaft 202i rotates, the pulley 106 is driven to rotate, the rotation of the pulley 106 drives the belt 107 to rotate, the rotation of the belt 107 drives another pulley 106 to rotate, the rotation of the pulley 106 drives the movable column 105 to rotate, the rotation of the movable column 105 drives the second bevel gear 104 to rotate, the second bevel gear 104 drives the first bevel gear 103 to rotate, the rotation of the first bevel gear 103 drives the stirring rod 102 to rotate, the stirring rod 102 can stir the hot melt adhesive in the mixing box 101, the stirring of the stirring rod 102 can make the particles of different sizes fully mixed, and then the hot melt adhesive is heated by the melting cylinder 108 to melt it.

[0070] When crushing a larger piece of hot melt adhesive, it is necessary to increase the moving frequency of the conical block 201b, and by moving the handle 302g, the handle 302g drives the rotating block 302f to rotate, and by rotating the rotating block 302f, the lower pressing bar 302e can be squeezed to make it rotate, and the lower pressing bar 302e can move the lower pressing block 302d when rotating, and when the lower pressing block 302d moves, it can drive the lower pressing rod 301g to move, and when the lower pressing block 302d moves, an extrusion force can be applied to the second spring 302i, and the handle 302g is rotated to rotate the rotating block 302f. In order to prevent the rebound force of the second spring 302i from driving the pressing block 302d to return to its original position, the handle 302g is moved to one side of the limit block 303a to squeeze it. At this time, the limit block 303a can be moved into the connecting frame 303b. When the limit block 303a moves into the connecting frame 303b, it can apply a squeezing force on the third spring 303d. When the handle 302g moves to the other side of the limit block 303a, the rebound force of the third spring 303d can make the limit block 303a return to its original position, thereby limiting the handle 302g and preventing it from rebounding.

[0071] The movement of the lower pressure rod 301g will drive the extrusion block 301f to squeeze the inclined surface block 301e. At this time, the inclined surface block 301e can drive the moving frame 301d to move. The movement of the moving frame 301d will drive the moving disk 301c to move. The moving disk 301c drives the driving column 201h to move. When the driving column 201h moves, it will drive the rotating wheel 201f and the driving wheel 201g to separate. At this time, the driving wheel 201g will not drive the rotating wheel 201f to rotate. When the driving column 201h moves, it will drive the rotating shell 301a and the driving shell 301b to engage. When the driving column 201h rotates, it can directly drive the rotating disk 201d to rotate. At this time, the rotation of the output shaft 202i can directly drive the cone block 201b to move, thereby increasing the crushing frequency of the cone block 201b and crushing larger hot melt adhesive blocks.
