Description

Technical Field

[0001] This invention relates to the field of fiber cotton processing technology, specifically to a web-reinforced fiber cotton composite layered material and its bonding device. Background Technology

[0002] Traditional fiber-cotton composite layered materials mostly use adhesives for bonding, which has problems such as being environmentally unfriendly, having a hard feel, and poor breathability. Existing technologies also use lamination, but existing laminated materials have insufficient interlayer bonding strength and are prone to delamination. Ultrasonic welding is a highly efficient, clean, and energy-saving solid-state joining technology, mainly used for thermoplastic plastics. Its core principle is to use high-frequency mechanical vibration (ultrasound) to generate frictional heat at the material contact interface, causing the material to partially melt and fuse and solidify under pressure, forming a strong molecular bond.

[0003] Application document with publication number CN117162501A discloses an ultrasonic welding device for fiber cotton, including an ultrasonic welding fixture. The ultrasonic welding fixture includes a welding head and an anvil. The welding head is provided with an ultrasonic transmitting module. The anvil is used to pair with the welding head to clamp the fiber cotton. The fiber cotton is a continuous roll material. The fiber cotton is installed on a roll feeding roller. The free end of the fiber cotton is clamped on a pair of pneumatic grippers. The ultrasonic welding device for fiber cotton also includes a pair of folding reversing rollers and a fiber cotton folding push rod. The fiber cotton folding push rod moves on a path perpendicular to the line connecting the two folding reversing rollers.

[0004] As mentioned in the above application, interlayer bonding of fiber cotton materials is usually achieved by methods such as sewing, ultrasonic welding, or bonding. For ultrasonic welding, if conventional methods are used, ultrasonic energy is usually applied directly to the upper surface of the fiber cotton and is expected to be transmitted to the interlayer connection. However, this transmission method has significant defects. Ultrasonic energy cannot be applied directly to the interlayer connection, which leads to severe energy attenuation during transmission, making it difficult to form effective melting and welding at the interlayer interface. At the same time, in order to compensate for energy loss, it is often necessary to increase the welding power, which not only increases energy consumption but may also cause damage or scorching of the fiber cotton surface material. In addition, the welding effect is extremely sensitive to the material thickness and uniformity, and the interlayer bonding strength is often insufficient and unstable. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a woven reinforced fiber cotton composite layered material and its bonding device.

[0015] As a further description of the above technical solution: a strip-shaped hole is formed through the side wall of the crossbeam along its length direction, and a sliding seat is slidably disposed in the strip-shaped hole. A connecting shaft is fixed at both ends of the welding seat along its length direction, and the other end of the connecting shaft extends outward through the sliding seat. A first return spring is fixed between the sliding seat and the inner wall of the strip-shaped hole.

[0022] Beneficial effects:

[0023] The present invention provides a bonding device for woven reinforced fiber cotton composite layered materials, which includes a conveying component and an unwinding component.

[0024] By installing a linkage component on the crossbeam, when the drive support roller rotates upward to tension the fiber cotton surface layer, the angle between the fiber cotton base layer and the fiber cotton surface layer before they are bonded increases. The linkage component synchronously drives the welding seat to move in the conveying direction of the conveying component, reducing the distance between the ultrasonic welding head and the bonding surface of the fiber cotton surface layer and the fiber cotton base layer, thereby reducing the attenuation of energy during transmission. When the drive support roller rotates downward to adjust the tension of the fiber cotton surface layer, the linkage component synchronously drives the welding seat to move in the opposite direction of the conveying component, preventing the ultrasonic welding head from affecting the movement of the fiber cotton base layer and the fiber cotton surface layer. Furthermore, no drive mechanism is required. When the drive support roller rotates for adjustment, the linkage component and the welding seat move synchronously, achieving automatic adjustment.

Detailed Implementation

[0035] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Example 1

[0037] Please see Figures 1-4 The technical problem to be solved in this embodiment is as follows: Ultrasonic energy is usually applied directly to the upper surface of the fiber cotton and is expected to be transmitted to the interlayer connection. However, this transmission method has significant defects. Ultrasonic energy cannot be applied directly to the interlayer connection, which causes severe energy attenuation during transmission, making it difficult to form effective melting and welding at the interlayer interface. At the same time, in order to compensate for energy loss, it is often necessary to increase the welding power, which not only increases energy consumption but may also cause damage or scorching of the fiber cotton surface material.

[0038] This invention provides a technical solution: a bonding device for a web-reinforced fiber cotton composite layered material, comprising:

[0039] The conveying assembly 1 is used to convey the fiber cotton base layer 10. The conveying assembly 1 includes a concave conveying frame 11 and two conveying rollers 12 rotatably disposed at both ends of the concave conveying frame 11 along the length direction. A conveyor belt 13 is wound between the two conveying rollers 12. Support legs 14 are installed at the bottom of the concave conveying frame 11.

[0040] The unwinding assembly 2 includes two supports 21 symmetrically arranged on both sides of the conveying assembly 1 along its length. A roller feeder 20 and a support roller 22 are rotatably mounted on the supports 21. A fiber cotton surface layer 23 is wound around the roller feeder 20. The roller feeder 20 is located directly above the conveyor belt 13, and the direction of the fiber cotton surface layer 23 released by the roller feeder 20 is consistent with the conveying direction of the conveyor belt 13.

[0041] The assembly includes a crossbeam 31 vertically fixed to two supports 21, a welding seat 32 movably disposed between the two crossbeams 31, and an ultrasonic welding head 33 fixed on the welding seat 32; a support frame 301 is welded to the lower surface of the end of the crossbeam 31 away from the support 21, and a connecting plate 302 is welded between the support frame 301 and the support 21.

[0042] The fiber cotton surface layer 23 released by the roller feeder 20 is guided by the support roller 22 and adheres to the upper surface of the fiber cotton base layer 10 conveyed by the conveying component 1 in an inclined state to form a bonding surface. The ultrasonic welding head 33 acts on this bonding surface to ultrasonically weld the fiber cotton surface layer 23 to the fiber cotton base layer 10. The ultrasonic welding head 33 is located in the angle space between the fiber cotton base layer 10 and the fiber cotton surface layer 23 before they are bonded.

[0043] In this embodiment, a conveying assembly 1 and an unwinding assembly 2 are provided. The fiber cotton base layer 10 is conveyed through the conveying assembly 1, and the fiber cotton surface layer 23 is unwound through the unwinding assembly 2 and is attached to the upper surface of the fiber cotton base layer 10 conveyed by the conveying assembly 1 in an inclined state. The ultrasonic welding head 33 is set in the angle space between the fiber cotton base layer 10 and the fiber cotton surface layer 23 before they are attached. This structural design allows the ultrasonic energy emitted by the ultrasonic welding head 33 to directly act on the interlayer bonding of the fiber cotton base layer 10 and the fiber cotton surface layer 23, overcoming the problem in the prior art that the ultrasonic energy acts on the bonding layer through the fiber surface layer, resulting in serious energy loss and easy damage to the fiber cotton surface layer.

[0044] Example 2

[0045] Please see Figure 1 , Figures 3-8The technical problem to be solved in this embodiment is that the fiber cotton surface layer 23 released by the roller feed roller 20 is guided by the support roller 22 and adheres to the upper surface of the fiber cotton base layer 10 conveyed by the conveying component 1 in an inclined state. When the tension of the fiber cotton surface layer 23 is adjusted by adjusting the support roller 22, the angle between the fiber cotton base layer 10 and the fiber cotton surface layer 23 before they are adhered will change. When the angle decreases, the space between the fiber cotton base layer 10 and the fiber cotton surface layer 23 before they are adhered will also decrease. When the angle increases, the space between the fiber cotton base layer 10 and the fiber cotton surface layer 23 before they are adhered will increase. Therefore, it is necessary to adjust the position of the ultrasonic welding head 33 to prevent the ultrasonic welding head 33 from affecting the movement of the fiber cotton base layer 10 and the fiber cotton surface layer 23, or to reduce the distance between the ultrasonic welding head 33 and the surface of the fiber cotton surface layer 23 adhering to the fiber cotton base layer 10 to reduce energy loss.

[0046] The bonding device for the woven reinforced fiber cotton composite layered material also includes: a linkage component 4 is provided on the crossbeam 31, and the linkage component 4 is connected to the welding seat 32 for transmission. When the drive support roller 22 rotates upward to tension the fiber cotton surface layer 23, the linkage component 4 synchronously drives the welding seat 32 to move in the conveying direction of the conveying component 1, thereby reducing the distance between the ultrasonic welding head 33 and the bonding surface of the fiber cotton surface layer 23 and the fiber cotton base layer 10.

[0047] The support roller 22 has two connecting arms 221 rotatably connected at both ends along its length, and a fixed shaft 222 rotatably connects the two brackets 21. The other ends of the two connecting arms 221 are fixed on the fixed shaft 222.

[0048] A drive mechanism is provided between the two supports 21. The drive mechanism is used to drive the support roller 22 to rotate. The drive mechanism includes an arc-shaped gear ring 201 and a rack 202. The arc-shaped gear ring 201 is welded and fixed on the connecting arm 221. The rack 202 is meshed with the arc-shaped gear ring 201. A first sliding groove 203 is provided on the support 21. A first slider 204 is welded on the rack 202. The first slider 204 is slidably connected to the first sliding groove 203. A strip seat 205 is welded between the bottom ends of the two racks 202. A base 206 is installed on the inner wall of the support 21 below the strip seat 205. An electric telescopic rod 207 is installed on the base 206. The top end of the electric telescopic rod 207 is fixedly connected to the strip seat 205.

[0049] Specifically, the drive mechanism is used to drive the support roller 22 to rotate in the following way: during use, the electric telescopic rod 207 is controlled to extend and retract. The extension and retraction of the electric telescopic rod 207 drives the strip seat 205 to move up and down. The strip seat 205 drives the strip rack 202 to move up and down. The strip rack 202 drives the arc-shaped gear ring 201 to rotate. The arc-shaped gear ring 201 drives the support roller 22 to rotate through the connecting arm 221, thereby adjusting the tension of the fiber cotton surface layer 23 guided by the support roller 22.

[0050] A strip-shaped hole 311 is opened through the side wall of the crossbeam 31 along the length direction. A sliding seat 312 is slidably arranged in the strip-shaped hole 311. A connecting shaft 313 is fixed at both ends of the welding seat 32 along the length direction. The other end of the connecting shaft 313 extends outward through the sliding seat 312. A first return spring 314 is fixed between the sliding seat 312 and the inner wall of the strip-shaped hole 311. A rectangular hole 315 is opened through the upper surface of the crossbeam 31 near the support 21. The rectangular hole 315 and the strip-shaped hole 311 are interconnected.

[0051] The linkage component 4 includes a first wedge block 41 welded to one side wall of the sliding seat 312 and a second wedge block 42 inserted into a rectangular hole 315. A connecting rod 43 is rotatably connected to the upper outer wall of the second wedge block 42. The other end of the connecting rod 43 is rotatably connected to the connecting arm 221 via a rotating shaft. A second slider 44 is welded to the side wall of the second wedge block 42. The second slider 44 is slidably connected to a second slide groove 45 opened on the bracket 21. A positioning shaft 46 that passes through the second slider 44 is inserted into the bottom plate inside the second slide groove 45. A second return spring 47 is sleeved on the positioning shaft 46 above the second slider 44.

[0052] Specifically, the linkage component 4 synchronously drives the welding seat 32 to move, and the specific way to adjust the position of the ultrasonic welding head 33 is as follows: based on the above embodiment, the tension of the fiber cotton surface layer 23 guided by the support roller 22 is adjusted by the connecting arm 221 driving the support roller 22 to rotate. When the connecting arm 221 rotates upward, the connecting arm 221 pulls the second wedge block 42 upward through the connecting rod 43. The upward movement of the second wedge block 42 pushes the first wedge block 41 to the left. The first wedge block 41 pushes the sliding seat 312 to the left in the strip hole 311 and squeezes it to make the first return spring 314 contract. The position of the welding seat 32 is adjusted by the sliding seat 312, and the position of the ultrasonic welding head 33 is adjusted by the welding seat 32.

[0053] In this embodiment, a linkage component 4 is provided on the crossbeam 31. The linkage component 4 is connected to the welding seat 32. When the drive support roller 22 rotates upward to tension the fiber cotton surface layer 23, the angle between the fiber cotton base layer 10 and the fiber cotton surface layer 23 before they are bonded increases. The linkage component 4 synchronously drives the welding seat 32 to move in the conveying direction of the conveying component 1, reducing the distance between the ultrasonic welding head 33 and the bonding surface of the fiber cotton surface layer 23 and the fiber cotton base layer 10, thereby reducing the energy attenuation during transmission. When the drive support roller 22 rotates downward to adjust the tension of the fiber cotton surface layer 23, the linkage component 4 synchronously drives the welding seat 32 to move in the opposite direction of the conveying component 1, preventing the ultrasonic welding head 33 from affecting the movement of the fiber cotton base layer 10 and the fiber cotton surface layer 23.

[0054] By setting the linkage component 4, the position of the ultrasonic welding head 33 can be adaptively adjusted according to the angle between the fiber cotton base layer 10 and the fiber cotton surface layer 23 before they are bonded together. This can reduce the distance between the ultrasonic welding head 33 and the bonding surface of the fiber cotton surface layer 23 and the fiber cotton base layer 10, thereby reducing energy attenuation during transmission. It can also prevent the ultrasonic welding head 33 from affecting the movement of the fiber cotton base layer 10 and the fiber cotton surface layer 23. Furthermore, there is no need to set up a drive mechanism. When the drive support roller 22 rotates for adjustment, the linkage component 4 moves synchronously with the welding seat 32 to achieve automatic adjustment.

[0055] Example 3

[0056] Please see Figures 1-2 The technical problem to be solved in this embodiment is that, based on the above embodiment, after adjusting the position of the ultrasonic welding head 33, it is necessary to adjust the angle of the ultrasonic welding head 33 so that the ultrasonic energy emitted by the ultrasonic welding head 33 can directly and accurately act on the interlayer joint.

[0057] The bonding device for the woven reinforced fiber cotton composite layered material also includes an angle adjustment mechanism. The angle adjustment mechanism is used to adjust the emission angle of the ultrasonic welding head 33. The angle adjustment mechanism includes a gear disk 316 and a horizontal rack 317. The gear disk 316 is sleeved and fixed on the connecting shaft 313. A third sliding groove 320 is opened on the side wall of the crossbeam 31. A third slider 318 is welded on the horizontal rack 317. The third slider 318 is slidably connected to the third sliding groove 320. A fixing block 319 is welded on the outer wall of the crossbeam 31. A hydraulic telescopic rod 321 is installed on the fixing block 319. The movable end of the hydraulic telescopic rod 321 is fixedly connected to the horizontal rack 317.

[0058] The first wedge block 41 and the second wedge block 42 have inclined surfaces on their opposite sides, and the opposite sides of the first wedge block 41 and the second wedge block 42 fit together. The second wedge block 42 has a structure that is narrow at the top and wide at the bottom.

[0059] Specifically, the welding seat 32 is inserted into the sliding seat 312 via the connecting shaft 313. Driving the connecting shaft 313 to rotate can cause the welding seat 32 to rotate, thereby adjusting the angle of the ultrasonic welding head 33 set on the welding seat 32. The specific adjustment method is to control the extension and retraction of the hydraulic telescopic rod 321, push the horizontal rack 317 to move, drive the gear disk 316 to rotate through the horizontal rack 317, drive the connecting shaft 313 to rotate through the gear disk 316, thereby causing the welding seat 32 to rotate, and thus adjusting the angle of the ultrasonic welding head 33 set on the welding seat 32.
