Description

Technical Field

[0001] The invention relates to the technical field of left and right side lamination of diapers, and more specifically, to left and right side lamination equipment and a lamination process thereof for producing diapers. Background Art

[0002] The basic structure of diapers usually includes non-woven fabrics, toilet paper, high-absorbency core layer (water-absorbent resin and fluff pulp), bottom film (PE film), elastic bands, adhesive tape (front + left and right), waist elastic band, etc.

[0003] Diaper left and right patch composite technology refers to the process of composite the left and right waist patches with non-woven fabrics during the diaper production process. First, the whole waist patch needs to be S-cut and divided into left and right patches. The left and right patches are then sprayed with fixing glue respectively and pasted to the two cut non-woven fabrics respectively. Finally, the cut non-woven fabrics are wrapped and folded in sequence to complete the diaper.

[0004] After the existing diapers are S-cut, the cutting blade is easily worn out due to long-term cutting, resulting in a decrease in cutting ability. Some areas of the waist patch are not completely cut, which makes it impossible to separate during subsequent transmission, and then the subsequent compounding work cannot be completed, resulting in a decrease in the compounding efficiency of the left and right patches.

[0005] Moreover, the left and right stickers are cut short after being separated and then dropped on the non-woven fabric for folding, which may easily cause the left and right stickers to be pasted on the non-woven fabric at an uneven level. If the left and right stickers are not pasted horizontally, the diaper may not fit the baby's body tightly, causing urine to leak from the sides, affecting the tightness of the diaper.

[0006] Therefore, it is necessary to design a diaper left and right sticker composite device that can automatically separate and horizontally stick the left and right stickers to improve the above-mentioned technical problems. Summary of the invention

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] For example, see Figure 1-9The present invention provides the following technical solutions: a left-right patch composite device for diaper production, comprising a base 1, a plurality of transmission rollers are connected to a bearing on one side of the base 1, a waist patch unwinding roller 2 is connected to a bearing on the upper left side of one side of the base 1, a non-woven fabric unwinding roller 5 is connected to a bearing on the lower left side of one side of the base 1, a winding roller 9 is connected to a bearing on the lower right side of one side of the base 1, an S-cutting mechanism 3 for cutting the non-woven fabric is provided on one side of the base 1, a separation mechanism 4 for separating the incompletely cut S-shaped left-right patches is provided on one side of the S-cutting mechanism 3, a left-right patch glue spraying mechanism 6 is provided on the lower side of the separation mechanism 4, a non-woven fabric unwinding roller 5 is provided with a non-woven fabric glue spraying mechanism 10, a horizontal pasting mechanism 7 for horizontally pasting the cut left-right patches on the non-woven fabric respectively on one side of the non-woven fabric glue spraying mechanism 10, and a folding mechanism 8 for folding the non-woven fabric is provided on one side of the horizontal pasting mechanism 7.

[0030] Specifically, the waist tape unwinding roller 2, the nonwoven fabric unwinding roller 5, the winding roller 9, the winding and cutting roller 31, the first roller 71 and the second roller 72 are all driven by an external motor.

[0031] See also Figure 2 The S-cutting mechanism 3 includes two rolling cutting rollers 31 connected to one side of the base 1 by bearings, and an S-shaped surrounding cutter 32 is fixedly connected to the outer side of each rolling cutting roller 31. Limiting rollers 34 are provided on both sides of the S-shaped surrounding cutter 32. The limiting rollers 34 are connected to the base 1 by bearings, and two limiting rings 33 are fixedly connected to the outer side of each limiting roller 34.

[0032] Specifically, when the two rolling and cutting rollers 31 rotate clockwise or counterclockwise respectively, the whole waist patch is cut into S-shaped left and right patches by the S-shaped surrounding cutter 32, and the two limiting rings 33 limit the whole waist patch in the middle to prevent the waist patch from being cut crookedly during S-cutting.

[0033] See also Figure 3 The separation mechanism 4 includes a first fixed plate 41 fixedly connected to one side of the base 1, and the upper sides of the first fixed plate 41 are respectively fixedly connected with the first cylinder 42 and the second cylinder 48, the output end of the first cylinder 42 is fixedly connected with the first double-axis cylinder 43, and the two output ends of the first double-axis cylinder 43 are both fixedly connected with the first clamping plate 44, the output end of the second cylinder 48 is fixedly connected with the second double-axis cylinder 47, and the two output ends of the second double-axis cylinder 47 are respectively fixedly connected with the second clamping plate 46, and a pressing component 45 is provided on one side of the first fixed plate 41.

[0034] Specifically, the extension of the output ends of the first cylinder 42 and the second cylinder 48 is used to control the movement of the first clamping plate 44 and the second clamping plate 46 respectively, the extension and retraction of the output end of the first double-axis cylinder 43 is used to control the clamping or release of the two first clamping plates 44, and the extension and retraction of the output end of the second double-axis cylinder 47 is used to control the clamping or release of the two second clamping plates 46.

[0035] See also Figure 4 The pressing assembly 45 includes a fixed block 451 fixedly connected to one side of the first fixed plate 41, a pressing block 452 is slidably connected inside the fixed block 451, two pressing springs 453 are fixedly connected to one side of the pressing block 452, the other end of the pressing spring 453 is fixedly connected to the inner wall of the fixed block 451, a touch pressure switch 454 is provided between the two pressing springs 453, and the touch pressure switch 454 is fixedly connected to the fixed block 451.

[0036] Specifically, when the pressing block 452 is squeezed, the two pressing springs 453 are compressed. When the two pressing springs 453 are compressed to the limit, the pressing block 452 squeezes the touch switch 454 .

[0037] See also Figure 5 The left and right glue spraying mechanism 6 includes a second fixed plate 63 fixedly connected to one side of the base 1, a storage tank 61 is fixedly connected to the upper side of the second fixed plate 63, and glue guns 62 are provided on both sides of the storage tank 61. The glue guns 62 penetrate the second fixed plate 63 and are fixedly connected to the second fixed plate 63.

[0038] Specifically, the storage tank 61 is used to store the fixing glue, and the glue spray gun 62 is connected to the storage tank 61 through a pipeline. The two glue spray guns 62 will spray the fixing glue in the storage tank 61 onto the cut left sticker and the right sticker respectively.

[0039] When the whole waist patch is completely cut, the left patch passes between the first clamping plate 44 and the pressing assembly 45, and the right patch passes between the second clamping plate 46 and the pressing assembly 45. The left and right patches are transferred to the bottom of the left and right patch glue spraying mechanisms 6 for glue spraying respectively.

[0040] When the whole waist patch is not completely cut by less than one millimeter, the whole waist patch that has been cut is pressed onto the surface of the pressing block 452, and the two pressing springs 453 press against the pressing block 452 through elastic force. At this time, since the area of ​​the whole waist patch that has not been completely cut is too small, the cut area of ​​the whole waist patch only needs to be pushed open and separated by the normal pressure of the pressing block 452.

[0041] When the whole waist sticker has not been completely cut by one millimeter or more, the whole waist sticker that has been cut is pressed onto the surface of the pressing block 452, and the two pressing springs 453 press against the pressing block 452 through elastic force. At this time, since the area of ​​the whole waist sticker that has not been completely cut is too large, the elastic force of the two pressing springs 453 is not enough to push the area of ​​the whole waist sticker that has not been completely cut apart, and the two pressing springs 453 are continuously compressed until the two pressing springs 453 are compressed to the limit, and the pressing block 452 is squeezed onto the pressure switch 454, and the pressure switch 454 presses the first double-axis cylinder 43, the second double-axis cylinder 47, and the first cylinder 42. The first and second cylinders 48 transmit signals, the first and second double-axis cylinders 43 and 47 respectively control the first and second clamps 44 and 46 to move, the first and second clamps 44 and 46 respectively clamp the left and right stickers, the output ends of the first and second cylinders 42 and 48 retract, and control the first and second clamps 44 and 46 to pull the left and right stickers respectively, thereby pulling and separating the areas where the left and right stickers are not completely cut, until the touch-pressure switch 454 is no longer squeezed, the first and second double-axis cylinders 43 and 47 control the first and second clamps 44 and 46 to release the left and right stickers and return to their positions.

[0042] By providing a pressure block 452, the small area of ​​the waist patch that is not completely cut is initially pushed open and separated. When the area of ​​the waist patch that is not completely cut becomes larger, the touch-pressure switch 454 is squeezed to control the first clamping plate 44 and the second clamping plate 46 to pull the left patch and the right patch respectively, thereby achieving a more efficient pulling and separation, effectively preventing the phenomenon that part of the waist patch is not completely cut, making it impossible to separate the left and right patches, and improving the composite efficiency of the left and right patches.

[0043] In the second embodiment, the left and right stickers are cut short after being divided, and then dropped on the non-woven fabric for folding, which may easily cause the positions of the left and right stickers on the non-woven fabric to be not level. If the left and right stickers are not level, the diaper may not fit the baby's body tightly, causing urine to leak from the sides, affecting the tightness of the diaper. Therefore, the following structure is designed to solve the above technical problems.

[0044] See also Figure 6The horizontal pasting mechanism 7 includes a third fixed plate 76 fixedly connected to one side of the base 1, and a first motor 79 is fixedly connected to one side of the third fixed plate 76. A second limit clamping assembly 74 and a first limit clamping assembly 78 are arranged inside the third fixed plate 76. The second limit clamping assembly 74 and the first limit clamping assembly 78 have the same structure. A connecting shaft 75 is fixedly connected between the first limit clamping assembly 78 and the second limit clamping assembly 74. A first guide block 73 is arranged on one side of the second limit clamping assembly 74, and a second guide block 77 is fixedly connected to one side of the first guide block 73. First rollers 71 and second rollers 72 are respectively arranged on both sides of the second guide block 77, and the first rollers 71 and second rollers 72 are both connected to the bearings of the base 1.

[0045] Specifically, the rotation of the output end of the first motor 79 is used to control the second limit clamping assembly 74 and the first limit clamping assembly 78 to rotate around the connecting shaft 75, and the first roller 71 and the second roller 72 are used to transfer the left and right stickers to the inside of the first guide block 73 and the second guide block 77 respectively.

[0046] See also Figure 7 The first limit clamping assembly 78 includes a fixing frame 782 fixedly connected to the output end of the first motor 79, the fixing frame 782 is fixedly connected with the first hydraulic cylinder 781 inside, the output end of the first hydraulic cylinder 781 is fixedly connected with the third double-axis cylinder 783, the two output ends of the third double-axis cylinder 783 are respectively fixedly connected with the third clamping plate 784 and the fourth clamping plate 785, the second material guide block 77 and the first material guide block 73 are both provided with a glue groove 787 inside, and a material groove is provided on one side of the glue groove 787, a second motor 786 is fixedly connected to one side of the third clamping plate 784, an extrusion plate 789 is provided inside the third clamping plate 784, the output end of the second motor 786 passes through the third clamping plate 784 and is fixedly connected with the extrusion plate 789, and a cutting module 788 is provided inside the first material guide block 73 and the second material guide block 77.

[0047] Specifically, the extension and retraction of the output end of the first hydraulic cylinder 781 is used to control the movement of the third clamping plate 784 and the fourth clamping plate 785, so that the third clamping plate 784 and the fourth clamping plate 785 are close to or away from the second material guide block 77, and the extension and retraction of the output end of the third double-axis cylinder 783 is used to control the third clamping plate 784 and the fourth clamping plate 785 to move closer or farther away, so as to loosen or clamp the right sticker. The right sticker first enters the inside of the material trough, and then the area of ​​the right sticker without spraying the fixing glue reaches between the third clamping plate 784 and the fourth clamping plate 785, and the area of ​​the right sticker sprayed with the fixing glue reaches the inside of the glue trough 787 to prevent the fixing glue from being pressed by the third clamping plate 784 and the fourth clamping plate 785. The rotation of the output end of the second motor 786 is used to control the rotation of the extrusion plate 789, so as to press the right sticker against the upper side of the non-woven fabric. The extrusion plate 789 is made of frosted glass that is not easy to stick.

[0048] See also Figure 8 The cutting module 788 includes a third motor 7882 fixedly connected to one side of the second material guide block 77, the output end of the third motor 7882 is fixedly connected to a gear 7883, the other side of the gear 7883 is connected to the internal bearing of the second material guide block 77, the interior of the second material guide block 77 is slidably connected to a cutter 7884, one side of the cutter 7884 is fixedly connected to a plurality of tooth columns 7881, and the tooth columns 7881 are meshingly connected to the gear 7883.

[0049] Specifically, the rotation of the output end of the third motor 7882 is used to control the rotation of the gear 7883. The rotation of the gear 7883 indirectly drives the cutter 7884 to move, thereby cutting the right sticker, and each connected right sticker is cut into a single right sticker.

[0050] See also Fig. 9 The folding mechanism 8 includes a fifth fixed plate 84 fixedly connected to one side of the base 1, and two guide plates 85 are fixedly connected to the upper side of the fifth fixed plate 84. The two guide plates 85 are installed at a forty-five degree angle relative to each other. A fourth fixed plate 82 is provided on the upper side of the fifth fixed plate 84. The fourth fixed plate 82 is fixedly connected to the base 1 and a second hydraulic cylinder 81 is fixedly connected to the upper side. The output end of the second hydraulic cylinder 81 passes through the fourth fixed plate 82 and is fixedly connected to a pressure block 83.

[0051] Specifically, the two non-woven fabrics fixed on the left and right sides pass through the guide plate 85, are guided and folded by the guide plate 85, and one side of the two folded non-woven fabrics is pressed on the top of the left and right sides respectively. The output end of the second hydraulic cylinder 81 extends to control the pressing block 83 to move downward, thereby pressing the left and right sides respectively inside the two non-woven fabrics.

[0052] When the right sticker needs to be bonded with the non-woven fabric, the first roller 71 and the second roller 72 rotate to transfer the right sticker to the inside of the second material guide block 77. At this time, the area of ​​the right sticker that has not been sprayed with fixing glue reaches between the third clamping plate 784 and the fourth clamping plate 785, and the area of ​​the right sticker that has been sprayed with fixing glue reaches the inside of the glue groove 787. The two output ends of the third double-axis cylinder 783 retract to control the third clamping plate 784 and the fourth clamping plate 785 to clamp the area of ​​the right sticker that has not been sprayed with fixing glue. The output end of the third motor 7882 rotates to control the gear 7883 to rotate. While the gear 7883 rotates, it indirectly drives the cutter 7884 to move, thereby cutting the right sticker.

[0053] The two connected right stickers are cut into a single right sticker, the output end of the first hydraulic cylinder 781 retracts to drive the single right sticker away from the second guide block 77, the output end of the first motor 79 rotates to control the single right sticker to rotate forty-five degrees clockwise and place it on the upper side of the non-woven fabric, the output end of the second motor 786 rotates to control the extrusion plate 789 to rotate, thereby pressing the single right sticker against the upper side of the fixing glue of the non-woven fabric. At this time, the single right sticker is fixed by the non-woven fabric, the two output ends of the third dual-axis cylinder 783 are opened, the third clamping plate 784 and the fourth clamping plate 785 no longer clamp the right sticker, the output end of the first motor 79 rotates to control the third clamping plate 784 and the fourth clamping plate 785 to rotate forty-five degrees counterclockwise, the output end of the first hydraulic cylinder 781 extends, controls the third clamping plate 784 and the fourth clamping plate 785 to return, and performs the next right sticker composite process.

[0054] The composite process of the left paste is the same as that of the right paste and will not be repeated here.

[0055] By controlling the third clamping plate 784 and the fourth clamping plate 785 to move and rotate, the single right and left stickers are respectively placed horizontally, which effectively prevents the left and right stickers from falling onto the non-woven fabric and failing to remain horizontally placed. After placement, the squeezing plate 789 presses them tightly against the upper side of the non-woven fabric fixing glue, which effectively prevents the single right sticker from being displaced during the conveying and folding process, thereby making the diaper fit tightly to the baby's body and preventing urine from leaking sideways.

[0056] Embodiment 3, a laminating process of left and right stickers for diaper production, according to the above-mentioned left and right sticker laminating equipment for diaper production, comprises the following steps: S1: The waist patch unwinding roller 2 unwinds the whole waist patch, and the S-cutting mechanism 3 cuts the whole waist patch into S-shaped left and right patches.

[0057] S2: The separation mechanism 4 separates the incompletely cut S-shaped left and right stickers. When passing the lower side of the left and right sticker glue spraying mechanism 6, the upper side of the left and right stickers is sprayed with fixing glue.

[0058] The more specific step of S2 is, S21: when the whole waist patch is completely cut, the left patch passes through the middle of the first clamping plate 44 and the pressing component 45, and the right patch passes through the middle of the second clamping plate 46 and the pressing component 45, and the left and right patches are transmitted to the bottom of the left and right patch glue spraying mechanism 6 for glue spraying respectively.

[0059] S22: When the entire waist patch is not completely cut by less than one millimeter, the cut entire waist patch is pressed onto the surface of the pressing block 452, and the two pressing springs 453 press against the pressing block 452 through elastic force. At this time, since the area of ​​the entire waist patch that is not completely cut is too small, the cut area of ​​the entire waist patch only needs to be pushed open and separated by the normal pressing of the pressing block 452.

[0060] S23: When the whole waist sticker has not been completely cut by one millimeter or more, the whole waist sticker that has been cut is pressed onto the surface of the pressing block 452, and the two pressing springs 453 press against the pressing block 452 through elastic force. At this time, since the area of ​​the whole waist sticker that has not been completely cut is too large, the elastic force of the two pressing springs 453 is not enough to push the area of ​​the whole waist sticker that has not been completely cut apart, and the two pressing springs 453 are continuously compressed until the two pressing springs 453 are compressed to the limit, and the pressing block 452 is squeezed onto the touch switch 454, and the touch switch 454 transmits a signal to the first double-axis cylinder 43, the second double-axis cylinder 47, the first cylinder 42, and the second cylinder 48.

The output ends of the first cylinder 42 and the second cylinder 48 retract, and control the first clamp plate 44 and the second clamp plate 46 to pull the left sticker and the right sticker respectively, thereby pulling and separating the areas where the left sticker and the right sticker are not completely cut, until the touch-pressure switch 454 is no longer squeezed, and the first biaxial cylinder 43 and the second biaxial cylinder 47 control the first clamp plate 44 and the second clamp plate 46 to release the left and right stickers and return to their positions.

[0061] S3: The non-woven fabric unwinding roller 5 unwinds the two non-woven fabrics after slitting, and the non-woven fabric glue spraying mechanism 10 applies the fixing glue on the upper sides of the two non-woven fabrics respectively.

[0062] S4: The horizontal pasting mechanism 7 cuts the left and right stickers that have been pasted with the fixing glue into short pieces again, and fixes the left sticker and the right sticker individually on the two non-woven fabrics.

[0063] The more specific steps of S4 are, S41: when the right sticker needs to be bonded with the non-woven fabric, the first roller 71 and the second roller 72 rotate to transfer the right sticker to the inside of the second material guide block 77, at this time, the area of ​​the right sticker that has not been sprayed with fixing glue reaches between the third clamping plate 784 and the fourth clamping plate 785, and the area of ​​the right sticker that has been sprayed with fixing glue reaches the inside of the glue groove 787, the two output ends of the third double-axis cylinder 783 retract, and the third clamping plate 784 and the fourth clamping plate 785 are controlled to clamp the area of ​​the right sticker that has not been sprayed with fixing glue, the output end of the third motor 7882 rotates to control the gear 7883 to rotate, and the gear 7883 rotates while indirectly driving the cutter 7884 to move, thereby cutting the right sticker.

[0064] S42: Two connected right stickers are cut into a single right sticker, the output end of the first hydraulic cylinder 781 retracts to drive the single right sticker away from the second material guide block 77, the output end of the first motor 79 rotates to control the single right sticker to rotate forty-five degrees clockwise and place it on the upper side of the non-woven fabric, the output end of the second motor 786 rotates to control the extrusion plate 789 to rotate, thereby pressing the single right sticker against the upper side of the fixing glue of the non-woven fabric, at this time the single right sticker is fixed by the non-woven fabric, the two output ends of the third double-axis cylinder 783 are opened, the third clamping plate 784 and the fourth clamping plate 785 no longer clamp the right sticker, the output end of the first motor 79 rotates to control the third clamping plate 784 and the fourth clamping plate 785 to rotate forty-five degrees counterclockwise, the output end of the first hydraulic cylinder 781 extends, controls the third clamping plate 784 and the fourth clamping plate 785 to return, and performs the next right sticker composite process.
