Description

Technical Field

[0001] The present invention relates to the technical field of diaper production, and in particular to diaper production equipment and a composite patch processing device. Background Art

[0002] As the usage rate of sanitary products such as diapers increases, their production scale is also expanding. Diapers usually have four composite patches, and two composite patches need to be laminated on both sides of the diapers during production. Traditional diaper production equipment needs to be equipped with two sets of composite patch processing devices on both sides of the production line to complete the conveying and cutting of the material belt, so that two composite patches of the same length are produced on each side of the production line, which greatly increases the processing cost of the composite patch and is not conducive to the large-scale production of diapers. Summary of the invention

[0003] Based on this, a diaper production equipment and a composite patch processing device are proposed, and the composite patch processing device can reduce the processing cost of the composite patch; thus, the diaper production equipment using the composite patch processing device has low production cost, which is conducive to the large-scale production of diapers.

[0004] The technical solution is as follows:

[0005] On the one hand, a composite patch processing device is provided, comprising: a dividing mechanism, the dividing mechanism comprising a rotating member capable of rotating around a central axis, a first cutting member connected to the rotating member, and a second cutting member connected to the rotating member, the second cutting member being spaced apart from the first cutting member; and a feeding mechanism, the feeding mechanism being used to convey the composite patch tape to be cut by the first cutting member and the second cutting member; wherein, when the rotating member rotates, the feeding speed of the feeding mechanism is adjustable so that the feeding length from the time of cutting by the first cutting member to the time of cutting by the second cutting member is the same or approximately the same as the feeding length from the time of cutting by the second cutting member to the time of cutting by the first cutting member.

[0006] The composite patch processing device of the above-mentioned embodiment, when processing the composite patch, utilizes the feeding mechanism to convey the composite patch material belt to the cutting mechanism, utilizes the rotation of the rotating member to drive the first cutting member and the second cutting member to rotate, and then utilizes the first cutting member and the second cutting member to cut the composite patch material belt, so that two composite patches can be obtained. Compared with the traditional method of using two sets of composite patch processing devices to prepare two composite patches, only the rotating member needs to be used to drive the first cutting member and the second cutting member to rotate to prepare two composite patches, thereby reducing the processing steps, improving the processing efficiency, and reducing the procurement cost of the processing device, thereby reducing the processing cost of the composite patch, and also saving production space, shortening the length of the production line, and reducing the difficulty of installation and subsequent maintenance. Among them, during the rotation of the rotating part, the process from the first cutting part cutting to the second cutting part cutting refers to the process in which the first cutting part cuts the composite patch tape for the first time and then the second cutting part cuts the composite patch tape for the second time, thereby obtaining the first composite patch; the process from the second cutting part cutting to the first cutting part cutting refers to the process in which the second cutting part cuts the composite patch tape for the second time and then the first cutting part cuts the composite patch tape for the third time, thereby obtaining the second composite patch. At the same time, since the feeding speed of the feeding mechanism can be flexibly adjusted, the feeding mechanism operates at the first feeding speed during the process from the first cutting part cutting the first time to the second cutting part cutting the second time, and the feeding mechanism operates at the second feeding speed during the process from the second cutting part cutting the second time to the first cutting part cutting the third time, thereby ensuring that the feeding lengths of the two adjacent cutting processes are the same or approximately the same, thereby ensuring that the obtained composite patch has the same or approximately the same length to meet the use requirements.

[0007] The technical solution is further described below:

[0008] In one embodiment, the linear velocity of the blade of the first cutting member is the same as the linear velocity of the blade of the second cutting member, the straight line from the blade of the first cutting member to the rotation center of the rotating member is the first straight line, the straight line from the blade of the second cutting member to the rotation center of the rotating member is the second straight line, the angle between the first straight line and the second straight line is the first angle and the second angle, the first angle is smaller than the second angle, and the first angle and the second angle are mutually combined; wherein, after the first cutting member cuts, when the second cutting member rotates through the first angle, the feeding mechanism performs an accelerated motion, and after the second cutting member cuts, when the second cutting member rotates through the second angle, the feeding mechanism performs a uniform motion, and the feeding length of the accelerated motion is the same or approximately the same as the feeding length of the uniform motion.

[0009] In one embodiment, the size of the first angle is adjustable.

[0010] In one of the embodiments, the composite patch processing device further includes a pressing member, which is spaced apart from the rotating member and can cooperate with the rotating member to form a feeding channel for pressing the composite patch tape and allowing the composite patch tape to pass through.

[0011] In one of the embodiments, the composite patch processing device further includes a buffer mechanism for buffering the composite patch tape, and the buffer mechanism is arranged between the feeding mechanism and the unwinding mechanism.

[0012] In one embodiment, the cache mechanism includes a swinging member, a supporting member, and a first tensioning member, the supporting member is rotatably connected to the swinging member, and the supporting member can separate the swinging member into a first swinging body arranged near the feeding mechanism, and a second swinging body arranged near the unwinding mechanism, the length of the first swinging body is greater than the length of the second swinging body, the first tensioning member is arranged below the second swinging body, and the composite bonding tape can pass through one end of the second swinging body, the first tensioning member and one end of the first swinging body in sequence.

[0013] In one embodiment, the cache mechanism also includes a second tensioning member arranged below the second swinging body, the second tensioning member is arranged between the second swinging body and the unwinding mechanism, the second tensioning member and the first tensioning member are spaced apart, and the composite bonding tape can pass through the second tensioning member, one end of the second swinging body, the first tensioning member and one end of the first swinging body in sequence.

[0014] In one embodiment, the cache mechanism further includes an auxiliary driving member, wherein the auxiliary driving member is connected to the swinging member, and the auxiliary driving member is used to auxiliary drive the swinging member to rotate around a connection portion between the supporting member and the swinging member.

[0015] In one embodiment, the feeding mechanism includes a first rotating wheel and a second rotating wheel which are relatively spaced apart, and a driving member for driving the first rotating wheel and / or the second rotating wheel to rotate, and the rotation speed of the driving member is adjustable.

[0016] On the other hand, a diaper production device is provided, including the composite patch processing device.

[0017] The diaper production equipment of the above-mentioned embodiment, when processing the composite patch, uses the feeding mechanism to convey the composite patch tape to the cutting mechanism, uses the rotation of the rotating member to drive the first cutting member and the second cutting member to rotate, and then uses the first cutting member and the second cutting member to cut the composite patch tape, so as to obtain two composite patches. Compared with the traditional method of using two sets of composite patch processing devices to prepare two composite patches, it is only necessary to use the rotating member to drive the first cutting member and the second cutting member to rotate to prepare two composite patches, thereby reducing the processing steps, improving the processing efficiency, and reducing the procurement cost of the processing device, thereby reducing the processing cost of the composite patch, and also saving production space, shortening the length of the production line, and reducing the difficulty of installation and subsequent maintenance, which is conducive to the large-scale production of diapers.

For example, "approximately", "approximately" or "substantially" can mean within one or more standard deviations, which are not limited here.

[0028] like Figure 1 As shown, in one embodiment, a composite patch processing device is provided, including a splitting mechanism 100 and a feeding mechanism 200. Thus, the feeding mechanism 200 is used to convey the composite patch tape 10, so that the composite patch tape 10 is conveyed to the splitting mechanism 100 for cutting, and then a composite patch that meets the use requirements is processed.

[0029] Among them, the dividing mechanism 100 includes a rotating member 110 that can rotate around a central axis, a first cutting member 120 connected to the rotating member 110, and a second cutting member 130 connected to the rotating member 110, the second cutting member 130 is spaced apart from the first cutting member 120, and the linear speed of the blade of the second cutting member 130 is the same as the linear speed of the blade of the first cutting member 120; the feeding mechanism 200 is used to transport the composite patch tape 10 to be cut by the first cutting member 120 and the second cutting member 130; and when the rotating member 110 rotates, the feeding speed of the feeding mechanism 200 is adjustable, so that the feeding length from the cutting of the first cutting member 120 to the cutting process of the second cutting member 130 is the same or approximately the same as the feeding length from the cutting of the second cutting member 130 to the cutting process of the first cutting member 120.

[0030] When the composite patch processing device of the above embodiment processes the composite patch, the feeding mechanism 200 is used to transport the composite patch tape 10 to the cutting mechanism 100, and the rotation of the rotating member 110 is used to drive the first cutting member 120 and the second cutting member 130 to rotate, and then the first cutting member 120 and the second cutting member 130 are used to cut the composite patch tape 10, so that two composite patches can be obtained. Compared with the traditional method of using two sets of composite patch processing devices to make two composite patches, only the rotating member 110 is used to drive the first cutting member 120 and the second cutting member 130 to rotate to make two composite patches, thereby reducing the processing steps, improving the processing efficiency, and reducing the procurement cost of the processing device, thereby reducing the processing cost of the composite patch, and also saving production space, shortening the production line length, and reducing the difficulty of installation and subsequent maintenance. Among them, during the rotation of the rotating member 110, the cutting process from the first cutting member 120 cutting to the second cutting member 130 refers to the process in which the first cutting member 120 cuts the composite patch tape 10 for the first time and then the second cutting member 130 cuts the composite patch tape 10 for the second time, thereby obtaining a first composite patch; the cutting process from the second cutting member 130 cutting to the first cutting member 120 refers to the process in which the second cutting member 130 cuts the composite patch tape 10 for the second time and then the first cutting member 120 cuts the composite patch tape 10 for the third time, thereby obtaining a second composite patch. At the same time, since the feeding speed of the feeding mechanism 200 can be flexibly adjusted, the feeding mechanism 200 operates at the first feeding speed during the process from the first cutting piece 120 cutting the first cut to the second cutting piece 130 cutting the second cut, and the feeding mechanism 200 operates at the second feeding speed during the process from the second cutting piece 130 cutting the second cut to the first cutting piece 120 cutting the third cut, thereby ensuring that the feeding lengths of two adjacent cutting processes are the same or approximately the same, and further ensuring that the prepared composite patch has the same or approximately the same length to meet the use requirements.

[0031] It should be noted that the lengths of the feed materials in the two processes are approximately the same and the lengths of the two composite patches are approximately the same, considering the actual impact of errors such as assembly error and processing error. Within the allowable error range, they can be considered the same. For example, when the difference in the lengths of the feed materials in the two processes is 0mm to 1mm, they can be considered the same, and when the difference in the lengths of the two composite patches is 0mm to 1mm, they can be considered the same.

[0032] The rotating member 110 can be in the form of a turntable, a rotating shaft, etc., and can be rotated by a motor or a gear drive, so that the first cutting member 120 and the second cutting member 130 can be driven to rotate around the corresponding rotating shaft, and then the composite patch tape 10 can be cut. For the sake of convenience, the clockwise rotation of the rotating member 110 is taken as an example. Of course, the rotating member 110 can also rotate counterclockwise under certain circumstances, as long as it can complete the cutting of the composite patch tape 10. The first cutting member 120 and the second cutting member 130 can be installed on the rotating member 110 by welding, clamping or plugging, etc., and it is only necessary to ensure that the installation is stable and can cut the composite patch tape 10. The first cutting member 120 and the second cutting member 130 are preferably in the form of a cutter, and the composite patch tape 10 is cut by the blade of the cutter.

[0033] The adjustment of the feeding speed can be flexibly selected according to the actual cutting situation. It only needs to ensure that the feeding lengths in two adjacent cutting processes are the same or approximately the same, so that composite patches with the same or approximately the same length can be produced.

[0034] like Figure 1 As shown, in one embodiment, the linear speed of the blade of the first cutting member 120 is the same as the linear speed of the blade of the second cutting member 130. In this way, the rotation trajectory of the blade of the first cutting member 120 and the rotation trajectory of the blade of the second cutting member 130 can overlap, which is conducive to adjusting the feeding speed of the feeding mechanism 200 to achieve the same feeding length. Figure 1 As shown, the straight line from the blade of the first cutting member 120 to the rotation center of the rotating member 110 is a first straight line 140, the straight line from the blade of the second cutting member 130 to the rotation center of the rotating member 110 is a second straight line 150, and the angle between the first straight line 140 and the second straight line 150 is a first angle (as shown in FIG. Figure 1α) and a second angle, the first angle is smaller than the second angle, and the first angle and the second angle are mutually combined. Wherein, after the first cutting member 120 cuts, when the second cutting member 130 rotates through the first angle, the feeding mechanism 200 performs an accelerated motion, and after the second cutting member 130 cuts, when the second cutting member 130 rotates through the second angle, the feeding mechanism 200 performs a uniform motion, and the feeding length of the accelerated motion is the same or approximately the same as the feeding length of the uniform motion. In this way, after the first cutting member 120 cuts the composite patch tape 10 for the first time until the second cutting member 130 cuts the composite patch tape 10 for the second time, the center angle of the area where the second cutting member 130 rotates is the first angle; after the second cutting member 130 cuts the composite patch tape 10 for the second time until the first cutting member 120 cuts the composite patch tape 10 for the third time, the center angle of the area where the second cutting member 130 rotates is the second angle. Since the first angle is smaller than the second angle, the rotation speed of the rotating member 110 remains unchanged. When the first composite patch is produced, the feeding mechanism 200 adopts an accelerated motion to accelerate the feeding, and when the second composite patch is produced, the feeding mechanism 200 adopts a uniform motion to perform normal uniform feeding, so that the feeding lengths of the two times can be the same or approximately the same, thereby ensuring that the lengths of the two composite patches are the same or approximately the same.

[0035] It should be explained that the first angle and the second angle can be arranged to form a complete 360° central angle, for example, the first angle is 36° and the second angle is 324°. The acceleration movement of the feeding mechanism 200 can be uniform acceleration or variable acceleration, as long as the preset length of the composite patch tape 10 can be supplied after the first cutting member 120 cuts the composite patch tape 10 for the first time until the second cutting member 130 cuts the composite patch tape 10 for the second time.

[0036] like Figure 3 As shown, when the coordinate system of the feeding speed and time of the feeding mechanism 200 is established, area A is the feeding length during uniform feeding, and area B is the feeding length during accelerated feeding. The area of ​​area A is equal to the area of ​​area B, that is, the feeding length during uniform feeding is equal to the feeding length during accelerated feeding.

[0037] Furthermore, the size of the first angle is adjustable. Thus, by changing the size of the first angle, the size of the second angle is also adjusted accordingly, thereby being able to meet the cutting requirements of composite stickers of different lengths. The size of the first angle can be adjusted by adjusting the installation position of the first cutting member 120 or the second cutting member 130 on the rotating member 110. Thus, the first cutting member 120 and the second cutting member 130 can be connected by a detachable connection such as a snap connection or a screw connection, so that the installation position can be adjusted to adjust the size of the first angle.

[0038] like Figure 1As shown, on the basis of any of the above embodiments, the composite patch processing device also includes a clamping member 300, and the clamping member 300 is spaced apart from the rotating member 110. The clamping member 300 can cooperate with the rotating member 110 to form a feeding channel (not marked) for clamping the composite patch tape 10 and for the composite patch tape 10 to pass through. In this way, by using the relative spacing between the clamping member 300 and the rotating member 110, the composite patch tape 10 will not slip during the conveying and cutting process, can be cut accurately, and can also ensure the accuracy of the feeding length, thereby ensuring that the length of the prepared composite patch meets the use requirements and has good consistency. Among them, the clamping member 300 can be correspondingly set as a turntable or a rotating shaft, and it only needs to be able to cooperate with the rotating member 110 to compress the composite patch tape 10 without affecting the conveying and cutting of the composite patch tape 10.

[0039] like Figure 1 and Figure 2 As shown, on the basis of any of the above embodiments, the composite patch processing device also includes a buffer mechanism 400 for buffering the composite patch tape 10, and the buffer mechanism 400 is arranged between the feeding mechanism 200 and the unwinding mechanism. In this way, the composite patch tape 10 can be buffered by the buffer mechanism 400, and can adapt to the change of the feeding speed of the feeding mechanism 200, so as to prevent the composite patch tape 10 from breaking. For example, it can prevent the composite patch tape 10 from being unable to follow up quickly when the feeding mechanism 200 is accelerating, thereby preventing the composite patch tape 10 from being broken due to the pulling force.

[0040] like Figure 1 As shown, specifically, the buffer mechanism 400 includes a swinging member 410, a supporting member 420, and a first tensioning member 430. The supporting member 420 is rotatably connected to the swinging member 410 by a rotating shaft or a hinge, and the supporting member 420 can separate the swinging member 410 into a first swinging body 411 disposed near the feeding mechanism 200 and a second swinging body 412 disposed near the unwinding mechanism. The length of the first swinging body 411 is greater than that of the second swinging body 412, and the first tensioning member 430 is disposed below the second swinging body 412. Figure 2As shown, the composite patch tape 10 can sequentially pass through one end 4121 of the second swinging member 412, the first tensioning member 430 and one end 4111 of the first swinging member 411. In this way, when the feeding mechanism 200 accelerates the feeding, the swinging member 410 rotates around the rotation axis of the connection part with the support member 420, so that one end 4111 of the first swinging member 411 rises and one end 4121 of the second swinging member 412 falls, so that one end of the second swinging member 410 moves toward the first tensioning member 430, and then the composite patch tape 10 between one end of the second swinging member 410 and the first tensioning member 430 is released, so that the supply of the composite patch tape 10 can adapt to the accelerated feeding of the feeding mechanism 200, and the composite patch tape 10 is prevented from being torn off. When the feeding mechanism 200 moves at a uniform speed and feeds at a uniform speed, the swinging member 410 rotates around the rotation axis of the connection part with the supporting member 420, so that one end 4111 of the first swinging member 411 descends and one end 4121 of the second swinging member 412 rises, thereby causing one end of the second swinging member 410 to move away from the first tensioning member 430, thereby tightening the composite patch tape 10 and buffering the composite patch tape 10 between one end of the second swinging member 410 and the first tensioning member 430 for release during the next acceleration movement.

[0041] like Figure 1 and Figure 2As shown, further, the cache mechanism 400 also includes a second tensioning member 440 arranged below the second swing body 412, the second tensioning member 440 is arranged between the second swing body 412 and the unwinding mechanism, the second tensioning member 440 and the first tensioning member 430 are arranged at intervals, and the composite patch tape 10 can pass through the second tensioning member 440, one end 4121 of the second swing body 412, the first tensioning member 430 and one end 4111 of the first swing body 411 in sequence. In this way, when the feeding mechanism 200 accelerates the feeding, the swing member 410 rotates around the rotation axis of the connection part with the support member 420, so that one end 4111 of the first swing member 411 rises and one end 4121 of the second swing member 412 falls, so that one end of the second swing member 410 moves toward the first tensioning member 430 and the second tensioning member 440, and then the composite patch tape 10 between one end of the second swing member 410 and the first tensioning member 430 and the composite patch tape 10 between one end of the second swing member 410 and the second tensioning member 440 are released, so that the supply of the composite patch tape 10 can better adapt to the accelerated feeding of the feeding mechanism 200 and avoid the composite patch tape 10 from being torn off. When the feeding mechanism 200 moves at a uniform speed and feeds at a uniform speed, the swinging member 410 rotates around the rotation axis of the connection part with the supporting member 420, so that one end 4111 of the first swinging member 411 descends and one end 4121 of the second swinging member 412 rises, thereby causing one end of the second swinging member 410 to move away from the first tensioning member 430 and the second tensioning member 440, thereby tightening the composite patch tape 10 and caching the composite patch tape 10 between one end of the second swinging member 410 and the first tensioning member 430 and between one end of the second swinging member 410 and the second tensioning member 440, so that more composite patch tapes 10 can be cached.

[0042] Preferably, the first tensioning member 430 and the second tensioning member 440 are arranged on the same horizontal plane, and one end of the second swinging member 410 is arranged between the first tensioning member 430 and the second tensioning member 440. After passing through the second tensioning member 440, one end of the second swinging member 410 and the first tensioning member 430, the composite patch tape 10 can be tightened to prevent the composite patch tape 10 from slipping during the conveying process, and the cached composite patch tape 10 can be better released without causing interference.

[0043] like Figure 1 and Figure 2As shown, in one embodiment, the cache mechanism 400 further includes an auxiliary driving member 450, which is connected to the swing member 410, and the auxiliary driving member 450 is used to assist in driving the swing member 410 to rotate around the connection portion between the support member 420 and the swing member 410. In this way, the auxiliary driving member 450 can assist in driving the swing member 410 to rotate, so that the composite patch tape 10 can be released more quickly, so as to better meet the accelerated feeding needs of the feeding mechanism 200, and the composite patch tape 10 can be tightened more quickly, so as to avoid the problem of the composite patch tape 10 slipping during the uniform feeding stage of the feeding mechanism 200, and ensure the stability and reliability of the feeding. Among them, the auxiliary driving member 450 can be set as a cylinder or a hydraulic cylinder, and the push rod of the cylinder or the hydraulic cylinder is welded or clamped to the swing member 410 (preferably, the push rod is connected to the first swing body 411, has a sufficiently large installation space, and will not affect the operation of the first tensioning member 430 and the second tensioning member 440). When the push rod moves telescopically, it drives the swing member 410 to rotate around the corresponding axis.

[0044] It should be noted that the swing member 410 can be configured as a rod or a column, and the support member 420 can be configured as a support column or a support bar. The first tensioning member 430 and the second tensioning member 440 can be configured in the form of a tensioning roller or a tensioning pulley. At the same time, in order to ensure that the composite patch tape 10 can run smoothly, corresponding rollers or pulleys can be provided at one end 4111 of the first swing body 411 and one end 4121 of the second swing body 412 for the composite patch tape 10 to pass through and be tensioned. The unwinding mechanism can include a material tray 500 around which the composite patch tape 10 is wound, and the rotation feeding of the material tray 500 can be pulled by the power of the feeding mechanism 200, or it can be actively rotated for feeding; there can be two material trays 500, one for feeding and the other for standby.

[0045] The feeding mechanism 200 can supply the composite patch tape 10 by rotating the feeding roller or by pulling the feeding sprocket. It only needs to be able to supply the composite patch tape 10 and adjust the feeding speed.

[0046] like Figure 1As shown, on the basis of any of the above embodiments, the feeding mechanism 200 includes a first rotating wheel 210, a second rotating wheel 220, and a driving member (not shown) for driving the first rotating wheel 210 to rotate and / or the second rotating wheel 220 to rotate, and the speed of the driving member is adjustable. In this way, the relative spacing of the first rotating wheel 210 and the second rotating wheel 220 can be used to further tighten the composite patch tape 10, so as to ensure that the composite patch tape 10 will not slip during the cutting process, and the cutting accuracy is ensured. Then, the driving member is used to drive the first rotating wheel 210 and the second rotating wheel 220 at the same time, or the driving member is used to drive the first rotating wheel 210 and the second rotating wheel 220 separately, so as to drive the first rotating wheel 210 and the second rotating wheel 220 to rotate accordingly, and then complete the corresponding feeding. At the same time, the feeding speed can also be adjusted by adjusting the speed of the driving member. Among them, the driving member can be a servo motor or other element that can change the speed.

[0047] In one embodiment, a diaper production device is also provided, comprising the composite patch processing device of any of the above embodiments.

[0048] When the diaper production equipment of the above embodiment processes the composite patch, the feeding mechanism 200 is used to convey the composite patch tape 10 to the cutting mechanism 100, and the rotation of the rotating member 110 is used to drive the first cutting member 120 and the second cutting member 130 to rotate, and then the first cutting member 120 and the second cutting member 130 are used to cut the composite patch tape 10, so that two composite patches can be obtained. Compared with the traditional method of using two sets of composite patch processing devices to prepare two composite patches, only the rotating member 110 is used to drive the first cutting member 120 and the second cutting member 130 to rotate to prepare two composite patches, thereby reducing the processing steps, improving the processing efficiency, and reducing the procurement cost of the processing device, thereby reducing the processing cost of the composite patch, and also saving production space, shortening the length of the production line, and reducing the difficulty of installation and subsequent maintenance, which is conducive to the large-scale production of diapers. At the same time, since the feeding speed of the feeding mechanism 200 can be flexibly adjusted, the feeding mechanism 200 operates at the first feeding speed during the process from the first cutting piece 120 cutting the first cut to the second cutting piece 130 cutting the second cut, and the feeding mechanism 200 operates at the second feeding speed during the process from the second cutting piece 130 cutting the second cut to the first cutting piece 120 cutting the third cut, thereby ensuring that the feeding lengths of two adjacent cutting processes are the same or approximately the same, and further ensuring that the prepared composite patch has the same or approximately the same length to meet the use requirements.

[0049] A composite patch processing device of any of the above embodiments can be arranged on both sides of the production line, so that four composite patches can be processed on both sides of the production line at the same time, and then the four composite patches can be fitted on the diapers. The two rotating members 110 of the two composite patch processing devices can be coaxially rotated synchronously using a driving source, or can be synchronously rotated using separate driving sources.

[0050] It should be noted that the composite patch processing device of the above embodiment can be used not only in diaper production equipment, but also in production equipment for sanitary products such as pull-up pants that require the use of composite patches, or in any other production equipment that requires the use of composite patches in any other scenario.

[0051] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as restrictions on the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
