Description

Technical Field

[0001] The utility model relates to the technical field of disposable sanitary product manufacturing equipment, in particular to the fields of baby / adult pull-up pants, baby / adult diapers, women's sanitary pants, women's sanitary napkins, etc., and more particularly to a fabric processing device that can precisely adjust the phase angle. Background Art

[0002] Disposable sanitary product manufacturing equipment often uses fabric processing devices for processing fabrics (single-layer materials or composite materials), such as 3D embossing devices, puncture devices, and stretching roller devices. These fabric processing devices (single-layer materials or composite materials) usually have a two-roller structure, one of which is provided with multiple teeth (convex parts) and valleys (concave parts) alternating along its circumference, and the other roller is provided with multiple valleys (concave parts) along at least its circumference. By using a drive mechanism to rotate the two rollers, at least one of the rollers' teeth is inserted into the valleys of the other roller without contact, so that the fabric is transported along the conveying direction and fed into the two rollers for processing.

[0003] In the above structure, because the teeth of one roller are inserted into the valley of the other roller, if the circumferential phase angle of one roller deviates from that of the other roller, that is, the teeth of one roller deviate from the valley of the other roller, the two rollers are prone to circumferential collision, causing damage to both rollers or even scrapping, forcing the disposable sanitary product equipment to shut down and affecting production. Therefore, the accuracy of the circumferential phase angle adjustment of this type of roller that requires insertion (negative gap) is particularly important. Utility Model Content

[0052] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the usual meanings understood by persons of ordinary skill in the field to which this utility model belongs. The words "first", "second" and similar terms used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "an" or "the" do not indicate a quantity limitation, but rather indicate the existence of at least one. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0054] It should be noted that the terms "up", "down", "left", "right", "front" and "back" used in the present invention are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0055] In order to make the present invention more clearly explained, it is necessary to explain the fabric. Figure 1 As shown, the utility model is a fabric processing device that can precisely adjust the phase angle. For the sake of convenience, a fabric processing device that can precisely adjust the phase angle in this embodiment is to extend (stretch) the fabric S. Of course, it can also be other processing of the fabric S, such as 3D embossing of the fabric S, puncturing of the fabric S, etc.

[0056] The fabric S can be a single layer material or a multi-layer composite material, such as a stretchable laminate. The fabric S is stretched (stretched) by the fabric processing device to improve its physical properties, such as increasing its flexibility, elasticity, tensile strength, tear strength, and uniformity.

[0057] In this embodiment, the stretching (stretching) of the fabric S is described as an example in which the fabric S is a three-layer stretchable laminate (composite material).

[0058] Combine Figure 1 and Figure 2 The fabric S includes a first substrate sheet S1, a second substrate sheet S2 (both the first substrate sheet S1 and the second substrate sheet S2 are non-woven fabrics) and an elastic film F disposed between the first substrate sheet S1 and the second substrate sheet S2.

[0059] The first substrate sheet S1, the second substrate sheet S2, and the elastic film F disposed between the first substrate sheet S1 and the second substrate sheet S2 are laminated by heat pressing or ultrasonic bonding, thereby forming a plurality of spaced joints J between the first substrate sheet S1 and the second substrate sheet S2. The heat pressing or ultrasonic bonding process generates heat melting energy, which melts the elastic film F, thereby bonding the first substrate sheet S1 and the second substrate sheet S2 to the elastic film F at the plurality of joints J. Furthermore, the elastic film F surrounding the joints J is melted, and in the stretched state, first openings K are formed around the joints J.

[0060] Because the elastic film F is a sheet material, its air permeability is poor. Although the first openings K can increase the air permeability of the elastic film F, the area of ​​these first openings K is relatively small, making it difficult to ensure the required breathability and comfort of the fabric S (stretch laminate). During the manufacturing process of this stretch laminate fabric S, the first substrate sheet S1, the second substrate sheet S2, and the elastic film F are heat-fused to form the fabric S. The fabric S is then stretched (elongated) using a fabric processing device capable of precisely adjusting the phase angle, as provided by the present invention.

[0061] Combine Figure 3 and Figure 4 After the fabric S is extended (stretched) using a fabric processing device capable of precisely adjusting the phase angle provided by the present invention, the fabric S stretches along the MD direction (the process direction of the fabric S processing), making the fabric S have better elasticity. In the stretched state, the first opening K around the joint J of the fabric S becomes larger, and the elastic membrane F located at the joint J is cut to form a second opening J1 of sufficient area located in the joint J, so that the fabric S has good air permeability.

[0062] It should be noted that the shape and size of the first opening K around the joint J of the fabric S and the second opening J1 located in the joint J are naturally formed during the extension (stretching) process of the fabric S using a fabric processing device that can precisely adjust the phase angle provided by the present invention. The present invention does not make any specific restrictions on the actual shape and size of the first opening K and the second opening J1.

[0063] like Figure 5 As shown, in order to achieve the extension (stretching) processing of the above-mentioned fabric S, according to an embodiment of the present invention, a fabric processing device capable of precisely adjusting the phase angle is provided, comprising a first roller 1 and a second roller 2 arranged in parallel along the axial direction and a precision adjustment component 5.

[0064] The fabric processing device further includes a frame 4 , a connecting assembly 10 , a first connecting member 6 , a first driving shaft 7 , a second connecting member 9 , a second driving shaft 8 and a driving assembly 11 .

[0065] A first sleeve 3a and a second sleeve 3b are mounted on the frame 4. The first roller 1 is mounted on the first sleeve 3a via a bearing, and the second roller 2 is mounted on the second sleeve 3b via a bearing.

[0066] Along the axial direction (the direction in which the first roller 1 and the second roller 2 extend), the first roller 1 is connected to the precision adjustment component 5, the first connecting piece 6 is connected to the precision adjustment component 5, one end of the first drive shaft 7 is connected to the first connecting piece 6, and the other end of the first drive shaft 7 is connected to the drive component 11.

[0067] Along the axial direction (the direction in which the first roller 1 and the second roller 2 extend), the connecting component 10 connects the second roller 2, the second connecting piece 9 connects the connecting component 10, one end of the second drive shaft 8 is connected to the second connecting piece 9, and the other end of the second drive shaft 8 is connected to the drive component 11.

[0068] The driving assembly 11 drives the first driving shaft 7 and the second driving shaft 8 to rotate synchronously in opposite directions in the circumferential direction, thereby driving the first roller 1 and the second roller 2 to rotate synchronously in opposite directions in the circumferential direction.

[0069] Specifically, the driving assembly 11 includes a first transmission wheel 11 a, a second transmission wheel 11 b, and a third transmission wheel 11 c. The first transmission wheel 11 a is connected to the first drive shaft 7, and the second transmission wheel 11 b is connected to the second drive shaft 8.

[0070] The first transmission wheel 11a and the second transmission wheel 11b are meshed with each other. The first transmission wheel 11a is connected to the third transmission wheel 11c via the first drive shaft 7, or the second transmission wheel 11b is connected to the third transmission wheel 11c via the second drive shaft 8. The third transmission wheel 11c is connected to a drive source (e.g., a motor, not shown). In this embodiment, the second transmission wheel 11b is connected to the third transmission wheel 11c via the second drive shaft 8.

[0071] Driven by a driving source (such as a motor), the third transmission wheel 11c drives the first transmission wheel 11a and the second transmission wheel 11b to rotate synchronously in opposite directions in the circumferential direction, thereby driving the first drive shaft 7 and the second drive shaft 8 to rotate synchronously in opposite directions in the circumferential direction, and driving the first roller 1 and the second roller 2 to rotate synchronously in opposite directions in the circumferential direction.

[0072] Combine Figure 6 and Figure 7 According to an embodiment of the present invention, a plurality of first teeth 1a and first valleys 1b are alternately formed on the outer circumference of the first roller 1, and a plurality of second valleys 2b are at least formed on the outer circumference of the second roller 2. The first teeth 1a of the first roller 1 are non-contactably inserted into the second valleys 2b of the second roller 2, thereby forming a working area for processing the fabric S.

[0073] Furthermore, in this embodiment, a plurality of second teeth 2a are provided on the outer circumference of the second roller 2. The second teeth 2a and the second valleys 2b are alternately provided on the outer circumference of the second roller 2. The first teeth 1a and the second teeth 2a are alternately inserted into the second valleys 2b and the first valleys 1b without contact with each other to form a working area for processing the fabric S.

[0074] That is, the first tooth portion 1 a is inserted into the second valley portion 2 b without contact, and the second tooth portion 2 a is inserted into the first valley portion 1 b without contact.

[0075] The first roller 1 and the second roller 2 of the present invention are configured to rotate synchronously in opposite directions along the circumferential direction (e.g. Figure 6 As shown by the arrows in the middle, when the first roller 1 and the second roller 2 rotate synchronously in opposite directions along the circumferential direction, the fabric S is transported along the transport direction and supplied to the working area of ​​the first roller 1 and the second roller 2. The fabric S is pressed by the tooth tips of the first tooth portion 1a and the second tooth portion 2a, so that the fabric S is extended (stretched). Figure 7 shown.

[0076] like Figure 6 As shown, in this embodiment, the angle between two adjacent first teeth 1a on the outer circumference of the first roller 1 is a1, and the angle between two adjacent second teeth 2a on the outer circumference of the second roller 2 is a2. To ensure that the first teeth 1a and the second teeth 2a are alternately and precisely inserted into the second valley 2b and the first valley 1 without contact, the angle a1 between two adjacent first teeth 1a is set to be equal to the angle a2 between two adjacent second teeth 2a, that is, a1 = a2.

[0077] like Figure 7As shown, in this embodiment, the depth of the first tooth portion 1a of the first roller 1 inserted into the second valley portion 2b of the second roller 2 is equal to the depth of the second tooth portion 2a of the second roller 2 inserted into the first valley portion 1b of the first roller 1. That is, the depth of the first tooth portion 1a inserted into the second valley portion 2b and the depth of the second tooth portion 2a inserted into the first valley portion 1b are both M (unit: mm). Here, the value of M is a negative number, that is, a negative gap. The working mode of the first roller 1 and the second roller 2 is an insertion structure.

[0078] In order to ensure the effect of stretching the fabric S, the depth of the first tooth portion 1a inserted into the second valley portion 2b and the depth M of the second tooth portion 2a inserted into the first valley portion 1b can be adjusted as needed. The specific adjustment process is described in detail in the following embodiments.

[0079] Because the first tooth portion 1a is inserted into the second valley portion 2b without contact, and the second tooth portion 2a is inserted into the first valley portion 1b without contact, when the circumferential phase angle of the first roller 1 deviates from the circumferential phase angle of the second roller 2, the first tooth portion 1a of the first roller 1 and the second tooth portion 2a of the second roller 2 can easily collide with each other in the circumferential direction, causing damage to or even failure of the first roller 1 and / or the second roller 2, forcing the disposable sanitary product equipment to shut down and affecting production. Therefore, the accuracy of the circumferential phase angle adjustment between the first roller 1 and the second roller 2 is particularly important.

[0080] In order to improve the accuracy of adjusting the circumferential phase angle between the first roller 1 and the second roller 2, the first roller 1 of the utility model is connected to the first connecting member 6 through the precision adjustment component 5, and the phase angle of the first roller 1 is adjusted by the precision adjustment component 5, thereby adjusting the deviation of the phase angle of the first roller 1 in the circumferential direction relative to the phase angle of the second roller 2 in the circumferential direction, thereby avoiding collision between the first tooth portion 1a of the first roller 1 and the second tooth portion 2a of the second roller 2 in the circumferential direction.

[0081] Specifically, combined Figure 5 、 Figures 8 to 11 According to an embodiment of the present invention, the precision adjustment assembly 5 includes a first flange disc 5a arranged along the axial direction, and a first adjustment member 5b connected to the first flange disc 5a.

[0082] The first flange 5a is connected to the first roller 1, so that the first roller 1 is connected to the precision adjustment component 5, and the first connecting member 6 is connected to the first adjusting member 5b of the precision adjustment component 5, so that the first connecting member 6 is connected to the precision adjustment component 5. Figure 8 shown.

[0083] like Figure 9As shown, the end surface of the first flange 5a has multiple first mounting holes 5a1 distributed along the circumference. The end surface of the first adjusting member 5b has multiple first mounting grooves 5b1 distributed along the circumference. The first mounting holes 5a1 and the first mounting grooves 5b1 correspond to each other in the circumferential direction. Bolts are inserted into the first mounting grooves 5b1 and the first mounting holes 5a1 to connect the first flange 5a to the first adjusting member 5b.

[0084] Combine Figures 8 to 11 The precision adjustment assembly 5 further includes a positioning member 5d, a clamp 5c, a first fixing member 5e, and a second fixing member 5f. The positioning member 5d is circumferentially connected to the first flange 5a, and the clamp 5c is circumferentially fixed to the first adjustment member 5b. The positioning member 5d and the clamp 5c correspond to each other in the circumferential direction.

[0085] The first fixing member 5e and the second fixing member 5f extend into the clamp 5c so that the first fixing member 5e and the second fixing member 5f clamp the positioning member 5d. The first fixing member 5e and the second fixing member 5f are respectively arranged perpendicular to the positioning member 5d.

[0086] Specifically, the first edge plate 5a is provided with a positioning hole 5a2, and the positioning member 5d is inserted into the positioning hole 5a2, so that the positioning member 5d is connected to the first edge plate 5a along the circumferential direction. Figure 9 and Figure 10 shown.

[0087] like Figure 11 As shown, the clamp 5c has a U-shaped structure, comprising a mounting portion 5c1, an opening 5c2, and ears 5c3 located on either side of the opening 5c2. A positioning member 5d is disposed within the opening 5c2 and connected to the first flange 5a. The clamp 5c is circumferentially secured to the first adjusting member 5b via the mounting portion 5c1.

[0088] A first fixing member 5e and a second fixing member 5f are installed in the ears 5c3 on both sides of the opening 5c2, respectively, and the first fixing member 5e and the second fixing member 5f extend into the opening 5c2 so as to clamp the positioning member 5d.

[0089] Specifically, screw holes extending axially along the first fixing member 5e and the second fixing member 5f are defined in the ears 5c3 on both sides of the opening 5c2, and the first fixing member 5e and the second fixing member 5f are installed in the screw holes defined in the ears 5c3 on both sides of the opening 5c2.

[0090] Combine Figure 13 and Figure 14 When the phase angle of the first roller 1 needs to be adjusted, the connection between the first flange 5a and the first adjusting member 5b is loosened, that is, the bolts inserted into the first mounting hole 5a1 and the first mounting groove 5b1 are loosened.

[0091] By synchronously adjusting the first fixing member 5e and the second fixing member 5f to move in the same direction in the ear portion 5c3 of the clamp 5c, the positioning member 5d is rotated by a certain angle along with the movement of the first fixing member 5e and the second fixing member 5f.

[0092] Specifically, the first fixing member 5e and the second fixing member 5f are rotated and screwed in the screw holes by a tool, thereby achieving the first fixing member 5e and the second fixing member 5f moving in the same direction. In this embodiment, the first fixing member 5e and the second fixing member 5f are screws and correspond to the size of the screw holes defined in the ear portion 5c3.

[0093] When the first fixing member 5e and the second fixing member 5f move in the same direction, if the first fixing member 5e moves toward the inside of the opening 5c2, the second fixing member 5f moves toward the outside of the opening 5c2; if the first fixing member 5e moves toward the outside of the opening 5c2, the second fixing member 5f moves toward the inside of the opening 5c2, thereby causing the positioning member 5d to rotate a certain angle along with the movement of the first fixing member 5e and the second fixing member 5f.

[0094] The positioning member 5d drives the first flange plate 5a to rotate a certain angle relative to the first adjusting member 5b, so that the first flange plate 5a drives the first roller 1 to rotate a certain angle, adjusts the phase angle of the first roller 1, and thereby adjusts the deviation of the phase angle of the first roller 1 in the circumferential direction relative to the phase angle of the second roller 2 in the circumferential direction, avoids the first tooth portion 1a of the first roller 1 and the second tooth portion 2a of the second roller 2 from colliding in the circumferential direction, and makes the first tooth portion 1a inserted into the second valley portion 2b without contact, and the second tooth portion 2a inserted into the first valley portion 1b without contact.

[0095] In order to quickly and accurately adjust the phase angle of the first roller 1, the pitch value Y (unit: mm) of the first fixing member 5e and the second fixing member 5f can be preset. The first fixing member 5e and the second fixing member 5f rotate one circle respectively, and the distance the first fixing member 5e and the second fixing member 5f move in the same direction is the pitch value Y. The positioning member 5d rotates as the first fixing member 5e and the second fixing member 5f move in the same direction. Figure 13 shown.

[0096] like Figure 14As shown, the positioning member 5d rotates along with the first fixing member 5e and the second fixing member 5f moving in the same direction, and drives the first flange plate 5a to rotate relative to the first adjusting member 5b by an angle b, so that the first flange plate 5a drives the first roller 1 to rotate by an angle b, adjusts the phase angle of the first roller 1, and thereby adjusts the deviation of the phase angle of the first roller 1 in the circumferential direction relative to the phase angle of the second roller 2 in the circumferential direction, avoids the first tooth portion 1a of the first roller 1 and the second tooth portion 2a of the second roller 2 from colliding in the circumferential direction, and ensures that the first tooth portion 1a is inserted into the second valley portion 2b without contact, and the second tooth portion 2a is inserted into the first valley portion 1b without contact.

[0097] In some embodiments, the number of rotations of the first and second fixing members 5e, 5f is determined based on the phase angle of the first roller 1 that needs to be adjusted, as described above. In the above data, the first and second fixing members 5e, 5f each rotate one rotation to obtain the pitch value Y and achieve the rotation angle b of the first roller 1 relative to the second roller 2. These values ​​need to be pre-set during the design of the fabric processing device to enhance convenience during actual adjustment operations.

[0098] When the positioning member 5d drives the first edge plate 5a to rotate a certain angle relative to the first adjusting member 5b and completes the phase angle adjustment of the first roller 1, the first mounting hole 5a1 is relatively displaced relative to the first mounting groove 5b1, and the first edge plate 5a is connected to the first adjusting member 5b by inserting bolts into the first mounting groove 5b1 and the first mounting hole 5a1.

[0099] The utility model uses the precision adjustment component 5 to precisely adjust the deviation of the phase angle of the first roller 1 in the circumferential direction relative to the phase angle of the second roller 2 in the circumferential direction, so that the first tooth portion 1a of the first roller 1 can be located in the middle position (optimal position) of the second valley portion 2b of the second roller 2 in the circumferential direction, thereby ensuring contactless movement.

[0100] like Figure 5 and Figure 12 As shown, in this embodiment, the connecting assembly 10 is connected to the second roller 2, and the second coupling member 9 is connected to the connecting assembly 10. The difference between the connecting assembly 10 and the precision adjustment assembly 5 is that the connecting assembly 10 is not provided with a positioning member and a clamp.

[0101] Specifically, the connecting assembly 10 includes a second flange 10a arranged axially, and a second adjusting member 10b connected to the second flange 10a. The second flange 10a is connected to the second roller 2, and the second connecting member 9 is connected to the second adjusting member 10b of the connecting assembly 10.

[0102] The end surface of the second flange 10a has multiple second mounting holes 10a1 distributed along the circumference. The end surface of the second adjusting member 10b has multiple second mounting grooves 10b1 distributed along the circumference. The second mounting holes 10a1 and the second mounting grooves 10b1 correspond to each other in the circumferential direction. Bolts are inserted through the second mounting grooves 10b1 and the second mounting holes 10a1 to connect the second flange 10a to the second adjusting member 10b.

[0103] In some embodiments, the connecting component 10 can also be provided with positioning parts and clamps in the same manner as the precision adjustment component 5. When the connecting component 10 is provided with the structure of positioning parts and clamps, the precision adjustment component 5 on the first roller 1 does not need to be provided with positioning parts 5d and clamps 5c. That is to say, only one of the first roller 1 and the second roller 2 needs to be connected to the structure of the precision adjustment component 5.

[0104] Back to Figure 5 According to an embodiment of the present invention, a surface material processing device capable of precisely adjusting a phase angle further includes a gap adjustment mechanism.

[0105] The gap adjustment mechanism connects the first sleeve 3a and the second sleeve 3b, and is used to adjust the gap between the first roller 1 and the second roller 2, thereby adjusting the depth M of the first tooth portion 1a inserted into the second valley portion 2b.

[0106] Specifically, in this embodiment, the gap adjustment mechanism includes a gap initial adjustment mechanism 12 and a gap fine adjustment mechanism 13 .

[0107] The gap initial adjustment mechanism 12 is connected to the first sleeve 3a or the second sleeve 3b, and is used to perform preliminary adjustment on the gap between the first roller 1 and the second roller 2, thereby performing preliminary adjustment on the depth M of the first tooth portion 1a inserted into the second valley portion 2b and the depth M of the second tooth portion 2a inserted into the first valley portion 1b.

[0108] In this embodiment, the gap initial adjustment mechanism 12 is connected to the second sleeve 3b, and the gap initial adjustment mechanism 12 pushes the second sleeve 3b to drive the second roller 2 to move closer to or away from the first roller 1, thereby performing a preliminary adjustment on the gap between the first roller 1 and the second roller 2, thereby performing a preliminary adjustment on the depth M of the first tooth portion 1a inserted into the second valley portion 2b and the depth M of the second tooth portion 2a inserted into the first valley portion 1b.

[0109] The gap fine-adjusting mechanism 13 is connected to the first sleeve 3a or the second sleeve 3b, and is used to precisely adjust the gap between the first roller 1 and the second roller 2, thereby precisely adjusting the depth M of the first tooth portion 1a inserted into the second valley portion 2b and the depth M of the second tooth portion 2a inserted into the first valley portion 1b.

[0110] In this embodiment, the gap fine-adjustment mechanism 13 is connected to the first sleeve 3a, and the gap fine-adjustment mechanism 13 pushes the first sleeve 3a to drive the first roller 1 to move closer to or away from the second roller 2, thereby precisely adjusting the gap between the first roller 1 and the second roller 2, thereby precisely adjusting the depth M of the first tooth portion 1a inserted into the second valley portion 2b and the depth M of the second tooth portion 2a inserted into the first valley portion 1b.

[0111] In addition, if the fabric S changes or the equipment is resized, when the gap between the first roller 1 and the second roller 2 needs to be changed, that is, when the depth M of the first tooth portion 1a inserted into the second valley portion 2b and the depth M of the second tooth portion 2a inserted into the first valley portion 1b change, the phase angle of the first roller 1 can also be adjusted by the precision adjustment component 5 to make appropriate adjustments to the depth M of the first tooth portion 1a inserted into the second valley portion 2b and the depth M of the second tooth portion 2a inserted into the first valley portion 1b.

[0112] In some embodiments, heating elements (not shown) are further provided inside the first roller 1 and the second roller 2 for heating the fabric S during the stretching (or stretching) process to achieve a better stretching effect on the fabric S. When the temperature setting of the heating elements changes, resulting in a deviation between the circumferential phase angle of the first roller 1 and the circumferential phase angle of the second roller 2, the phase angle of the first roller 1 can be adjusted using the precision adjustment assembly 5 to adjust the deviation between the circumferential phase angle of the first roller 1 and the circumferential phase angle of the second roller 2.

[0113] There are a few points to note:

[0114] (1) The drawings of the embodiments of the present invention only relate to the structures related to the embodiments of the present invention. Other structures may refer to conventional designs.
