Description

Technical Field

[0001] This utility model relates to the field of diaper production technology, specifically to a high-efficiency diaper elastic fabric composite equipment. Background Technology

[0002] In diaper production, multiple sets of elastic bands need to be symmetrically bonded to the outer non-woven fabric. When bonding the elastic bands to the outer non-woven fabric, adhesive needs to be applied to the elastic bands. However, existing rubber adhesives are generally applied by spraying, which easily leads to uneven adhesive application on the outer wall of the elastic bands. Furthermore, only a portion of the adhesive adheres to the elastic bands during spraying, leaving some unused, resulting in an overall need to improve adhesive utilization.

[0003] Based on this, this utility model designs a high-efficiency diaper elastic fabric composite device to solve the above problems. Utility Model Content

[0040] Example 1

[0041] Please refer to the instruction manual appendix. Figure 1-7 ,

[0042] A high-efficiency diaper elastic fabric laminating device includes a frame 1. The high-efficiency diaper elastic fabric laminating device is used to assemble elastic bands 2 onto the outer nonwoven fabric 3.

[0043] The frame 1 is connected to a guide assembly 6 for guiding the outer nonwoven fabric 3;

[0044] A glue-applying assembly 4 for coating the outer wall of the elastic band 2 is connected to the frame 1;

[0045] The adhesive application assembly 4 includes a heating assembly 41, a first mounting plate 42, and a through-type coating assembly. The first mounting plate 42 is fixedly installed on the front side of the frame 1. The heating assembly 41 for heating the adhesive in the through-type coating assembly to a stable flow state is fixedly connected to the side wall of the first mounting plate 42 near the guide cloth assembly 6. The heating end of the heating assembly 41 is connected to the through-type coating assembly for uniformly coating the outer wall of the elastic band 2 with adhesive. The through-type coating assembly contains adhesive, and multiple sets of elastic bands 2 are inserted into the through-type coating assembly and slide relative to the through-type coating assembly.

[0046] The frame 1 is connected to a tensioning assembly 5 for tensioning the elastic band 2 at the lower right of the first mounting plate 42;

[0047] The frame 1 is connected to a guide assembly 7 on the right side of the tensioning assembly 5 for guiding multiple sets of elastic bands 2 and dividing the multiple sets of elastic bands 2 into two rows. The guide assembly 7 is located on the side of the tensioning assembly 5 away from the guide cloth assembly 6.

[0048] The adhesive coating component 4 guides the outer nonwoven fabric 3. At the same time, the guiding component 7 guides multiple sets of elastic bands 2 and divides them into two rows. Then, the tensioning component 5 tensions the elastic bands 2. The heating component 41 of the adhesive coating component 4 heats the adhesive in the through-type coating component to a stable flow state. After the elastic bands 2 pass through the through-type coating component, the outer wall of the elastic bands 2 is uniformly coated with adhesive. After the adhesive is applied, the elastic bands 2 come into contact with the outer nonwoven fabric 3. Then, external equipment dries the adhesive, so that the elastic bands 2 are stably and uniformly bonded to the outer nonwoven fabric 3. The continuous operation is highly efficient.

[0049] The fabric guiding assembly 6 includes a first guide roller 61, a second guide roller 62, a third guide roller 63, and a fourth guide roller 64. All four rollers are located on the same side of the frame 1 and are parallel to each other. All rollers are rotatably connected to the frame 1. The second guide roller 62 is located to the upper left of the first guide roller 61, the third guide roller 63 is located to the upper right of the second guide roller 62, and the fourth guide roller 64 is located above the left end of the third guide roller 63.

[0050] The top of the second guide roller 62 is in contact with the bottom of the outer nonwoven fabric 3, the bottom of the first guide roller 61 is in contact with the top of the outer nonwoven fabric 3, and the third guide roller 63 and the fourth guide roller 64 are in sliding contact with the bottom of the outer nonwoven fabric 3. The first guide roller 61, the second guide roller 62, the third guide roller 63 and the fourth guide roller 64 guide the outer nonwoven fabric 3 so that the outer nonwoven fabric 3 is transported sequentially along the direction of the second guide roller 62, the first guide roller 61, the third guide roller 63 and the fourth guide roller 64.

[0051] The through-type coating assembly includes a hopper 43, a feed pipe 44, a first through hole 45, and a second through hole 46. The end of the hopper 43 away from the guide cloth assembly 6 is fixedly connected to the heating end of the heating assembly 41. The feed pipe 44 is fixedly connected to the feed hole at the top of the hopper 43. The first through hole 45 is opened at the left end of the hopper 43, and the second through hole 46 is opened at equal intervals at the lower right end of the hopper 43. The central axis of the first through hole 45 coincides with the central axis of the second through hole 46. The first through hole 45, the hopper 43, and the second through hole 46 cooperate to allow the rubber band 2 to pass through.

[0052] The feed pipe 44 is connected to the external glue supply structure;

[0053] The inner diameter of the second through hole 46 is the same as the outer diameter of the rubber band 2, and the inner radius of the first through hole 45 is the sum of the radius of the rubber band 2 and the thickness of the adhesive coating.

[0054] An external adhesive supply structure feeds adhesive into the hopper 43 through the feed pipe 44 of the through-type coating component. The heating component 41 heats the hopper 43 to a stable flow state. The elastic band 2 moves into the hopper 43 through the second through hole 46. The adhesive in the hopper 43 coats the outer wall of the elastic band 2. After passing through the first through hole 45 and being scraped off, the outer wall of the elastic band 2 is uniformly coated with adhesive, which is beneficial for uniform bonding in the later stage. Compared with spraying adhesive, it saves the amount of adhesive used.

[0055] The tensioning assembly 5 includes two side plates 51, a torsion spring 52, two movable rods 53, and a connecting shaft 54. The connecting shaft 54 ​​is fixedly installed on the side wall of the frame 1. The front end of the connecting shaft 54 ​​is rotatably connected to the middle of the movable rod 53 at the rear end through a bearing. The outer end of the torsion spring 52 is fixedly connected to the rear side wall of the movable rod 53 at the rear end, and the inner end of the torsion spring 52 is fixedly connected to the outer wall of the connecting shaft 54. The outer end of the movable rod 53 at the rear end is symmetrically fixedly connected to two side plates 51. The front end of the side plates 51 is fixedly connected to the inner end of the movable rod 53 at the front end, and the elastic band 2 is located between the two sets of side plates 51. This arrangement allows the two side plates 51 and the two movable rods 53 to cooperate to form a rectangular frame structure. The two sets of elastic bands 2 are located inside the rectangular frame structure and are respectively located near the ends of the rectangular frame.

[0056] The elastic band 2 is threaded between the two sets of side plates 51. The restoring force of the torsion spring 52 drives the movable rod 53 to rotate, and the movable rod 53 drives the side plates 51 to rotate. The two sets of side plates 51 bend and tension the elastic band 2, ensuring that the elastic band 2 is in a taut state.

[0057] The guide assembly 7 is located on the side of the tensioning assembly 5 away from the guide cloth assembly 6. The guide assembly 7 includes a first guide limiting roller 71, a second guide limiting roller 72, a second mounting plate 73, a third mounting plate 74, a fourth mounting plate 75, an inclined three-way guide limiting roller 76, and a third guide limiting roller 77;

[0058] The first guide limiting roller 71 is rotatably connected to the top of the frame of the machine frame 1. The second mounting plate 73 is fixedly installed on the front side wall of the machine frame 1. The third guide limiting roller 77 is rotatably connected to the left side wall of the front end of the second mounting plate 73. The first guide limiting roller 71 and the third guide limiting roller 77 are arranged parallel to the front side wall of the machine frame 1, and the first guide limiting roller 71 is located above the third guide limiting roller 77.

[0059] The top of the second mounting plate 73 is symmetrically fixedly connected to the fourth mounting plate 75, namely the fourth mounting plate 75 on the front side and the fourth mounting plate 75 on the rear side. The lower end of each fourth mounting plate 75 is rotatably connected to the inclined three-guide limiting roller 76.

[0060] The second mounting plate 73 is symmetrically fixedly connected to the left side wall of the third mounting plate 74, namely the front third mounting plate 74 and the rear third mounting plate 74. The left end of each third mounting plate 74 is rotatably connected to the second guide limiting roller 72.

[0061] The inclined three-guide limiting roller 76 is set lower than the third guide limiting roller 77, and the second guide limiting roller 72 is set lower than the inclined three-guide limiting roller 76;

[0062] The first guide limiting roller 71 of the guide assembly 7 guides multiple sets of elastic bands 2, which are perpendicular to the frame 1, to above the third guide limiting roller 77. The third guide limiting roller 77 sets multiple sets of elastic bands 2, which are parallel to the frame 1, perpendicular to the frame 1. Half of the elastic bands 2 move below the front oblique three-guide limiting roller 76, and the other half move below the rear oblique three-guide limiting roller 76. The front oblique three-guide limiting roller 76 guides the elastic bands 2 to below the front second guide limiting roller 72, and the rear oblique three-guide limiting roller 76 guides the elastic bands 2 to below the rear second guide limiting roller 72, and then sends them into the tensioning assembly 5 and the gluing assembly 4. This facilitates the guidance of the multiple sets of elastic bands 2, which are perpendicular to the frame 1, and divides the multiple sets of elastic bands 2 into two rows, making it easier to guide the two rows of elastic bands 2 in the compounding direction, which is beneficial for practical use.
