Description

Technical Field

[0001] The present invention relates to the technical field of textile processing, and more particularly to a wrinkle-free bonding device and method for blended high-elastic double-layer fabrics. Background Art

[0002] Double-layer and multi-layer fabrics can be obtained directly from the weaving process, or they can be obtained by gluing, sewing or other processing of two or more single-layer fabrics. Double-layer and multi-layer fabrics have a wide range of applications and can be widely used in down jacket fabrics, reversible fabrics, special thick fabrics and many other fields. Therefore, the use of double-layer and multi-layer fabrics has attracted more and more attention.

[0003] When traditional blended high-elastic double-layer fabrics are bonded, the double-layer fabrics need to be stretched so that the double-layer fabrics can be fully unfolded to avoid wrinkles. However, the existing technology can only forcibly pull the double-layer fabrics to unfold, resulting in elastic deformation of the double-layer fabrics and excessive unfolding, which causes the double-layer fabrics to still have wrinkle problems when bonded. At the same time, the existing technology does not clean the double-layer fabrics before bonding, resulting in debris left on the bonding side of the double-layer fabrics, affecting the bonding effect.

[0004] In view of the above technical defects, a solution is now provided. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: In view of the fact that the existing technology can only forcibly pull and unfold the double-layer fabric, resulting in elastic deformation of the double-layer fabric and excessive unfolding, which in turn causes the double-layer fabric to still have wrinkles when bonding, the following technical solution is proposed to solve this problem:

[0032] Refer to the instruction manual Figure 1-Figure 7 , a wrinkle-free bonding device for blended high-elastic double-layer fabrics, such as Figure 1 and Figure 2 As shown, it includes a base 1, two feeding rollers 2 are provided on the top of the base 1, the outer walls of the two feeding rollers 2 are provided with fabrics 3, a pressing roller 4 is provided on one side of the two fabrics 3, the pressing roller 4 is installed on the top of the base 1, and a sweeping and pulling mechanism 5 is provided on the top of the base 1;

[0033] like Figure 3 and Figure 4 As shown, the sweeping and pulling mechanism 5 includes motors 51 fixedly mounted on both sides of the top of the base 1. A first gear 52 is provided on one side of the two motors 51. The first gear 52 is driven to rotate by the synchronous start of the two motors 51. The tops of the two first gears 52 are engaged with second gears 53. The two second gears 53 are rotatably mounted on the top of the base 1. The two second gears 53 are symmetrically arranged with each other, that is, the two first gears 52 drive the two second gears 53 to rotate synchronously.

[0034] like Figure 3 and Figure 4As shown, a first pulley 54 is provided on one side of the two first gears 52 and the second gear 53, and then the two first gears 52 and the second gear 53 rotate to drive the first pulley 54 to rotate, and multiple first pulleys 54 are arranged corresponding to each other, and the outer walls of the multiple first pulleys 54 are rotatably installed with a synchronous belt 55, and the tops of the multiple synchronous belts 55 are rotatably installed with a second pulley 56. The multiple second pulleys 56 are arranged in pairs corresponding to each other, and one side of the multiple second pulleys 56 is respectively rotatably installed with a support frame 57, and the support frame 57 is fixedly installed on the top of the base 1, so that the first pulley 54 drives the second pulley 56 to rotate synchronously through the second pulley 56.

[0035] like Figure 3 and Figure 4 As shown, a rotating wheel 58 is fixedly installed on one side of the plurality of first pulleys 54 and the second pulley 56, and a transfer belt 59 is rotatably installed on the outer wall of the plurality of rotating wheels 58. The plurality of transfer belts 59 are arranged in pairs corresponding to each other, that is, the plurality of first pulleys 54 and the second pulley 56 drive the rotating wheels 58 and the transfer belt 59 to rotate synchronously. The plurality of transfer belts 59 are respectively located on the outer sides of the two fabrics 3. The outer walls of the plurality of transfer belts 59 are fixedly installed with a plurality of rubber paddles 510, and then the plurality of transfer belts 59 respectively drive the plurality of rubber paddles 510 on their outer walls to rotate on the outer walls of the two fabrics 3. The plurality of rubber paddles 510 and the outer walls of the fabrics 3 fit together, so that the plurality of transfer belts 59 drive the plurality of rubber paddles 510 in a pair-by-two corresponding manner.

[0036] That is, any two corresponding transfer belts 59 on both sides clamp the outer wall of the fabric 3 and synchronously pull the two sides of the fabric 3 by rotating, so that the two sides of the fabric 3 are always subjected to a pulling force toward the two sides, that is, the fabric 3 can be pulled and unfolded by a gentle force, thereby avoiding the situation where the two sides of the double-layer fabric 3 are pulled hard and deformed.

[0037] like Figure 5 and Figure 6 As shown, a pushing mechanism 6 is provided on one side of the two first gears 52, and the pushing mechanism 6 includes a reciprocating threaded rod 61 fixedly installed on one side of the two first gears 52, so that when the two first gears 52 rotate, the reciprocating threaded rod 61 is driven to rotate synchronously, and the two reciprocating threaded rods 61 are symmetrically arranged. The outer walls of the two reciprocating threaded rods 61 are threadedly connected to a pushing rack 62, and the two pushing racks 62 are slidably installed on the top of the base 1. The outer walls of the two pushing racks 62 are respectively slidably installed with two slides 63, that is, the two reciprocating threaded rods 61 drive the pushing rack 62 and the two slides 63 to move synchronously.

[0038] like Figure 5 and Figure 6As shown, the outer walls of the two slides 63 are respectively fixedly installed with squeeze boxes 64, and the multiple squeeze boxes 64 driven by the two slides 63 are respectively moved synchronously on the outer walls of the two fabrics 3, and the multiple squeeze boxes 64 are arranged in pairs corresponding to each other, and the multiple squeeze boxes 64 are arranged in an inclined state. The multiple squeeze boxes 64 and the two fabrics 3 are arranged in correspondence with each other, and the corresponding positions are synchronously slid according to the height and position of the two fabrics 3. The inner wall of the squeeze box 64 is slidably installed with a rubber clamping push plate 65, and the outer wall of the rubber clamping push plate 65 is in contact with the outer wall of the fabric 3. A support spring 66 is fixedly installed on one side of the rubber clamping push plate 65, and then the rubber clamping push plate 65 is pushed to fit the outer wall of the fabric 3 through the support spring 66 on the squeeze box 64;

[0039] The support spring 66 is fixedly installed on the inner wall of the squeezing box 64, so that any two corresponding squeezing boxes 64 drive the rubber clamping push plates 65 to clamp the outer walls on both sides of the fabric 3, and at the same time squeeze the folded or raised parts on both sides of the fabric 3 by moving, to avoid the outer walls on both sides of the fabric 3 from folding or raising, so that the fabric 3 can be bonded in a flat manner.

[0040] When the two first gears 52 rotate, the two reciprocating threaded rods 61 are driven to rotate synchronously, that is, the two reciprocating threaded rods 61 drive the pushing frame 62 and the two slides 63 to move synchronously. The multiple squeezing boxes 64 driven by the two slides 63 move synchronously on the outer walls of the two fabrics 3 respectively, and slide synchronously to the corresponding positions according to the height and position of the two fabrics 3. The support springs 66 on the squeezing boxes 64 push the rubber clamping push plates 65 to fit the outer walls of the fabrics 3, so that any two corresponding squeezing boxes 64 drive the rubber clamping push plates 65 to clamp the outer walls of the two sides of the fabric 3. At the same time, the folded or warped parts on both sides of the fabric 3 are squeezed by moving to avoid folding or warping of the outer walls of the two sides of the fabric 3, so that the fabrics 3 can be bonded in a flat manner.

[0041] And multiple first pulleys 54 and second pulleys 56 drive the rotating wheel 58 and the transfer belt 59 to rotate synchronously, and then the multiple transfer belts 59 respectively drive multiple rubber paddles 510 on their outer walls to rotate on the outer walls of the two fabrics 3. The multiple transfer belts 59 drive the multiple rubber paddles 510 in a pairwise corresponding manner, that is, any two corresponding transfer belts 59 on both sides clamp the outer wall of the fabric 3, and synchronously pull the two sides of the fabric 3 by rotation, so that the two sides of the fabric 3 are always subjected to a tensile force toward the two sides, that is, the fabric 3 can be stretched by a gentle force, thereby avoiding the situation where the two sides of the double-layer fabric 3 are pulled hard and deformed.

[0042] Example 2: In the prior art, since the double-layer fabrics are not cleaned before bonding, debris is left on one side of the double-layer fabrics, affecting the bonding effect. To solve this problem, the following technical solution is proposed:

[0043] like Figure 1 and Figure 7 As shown, a top scraping mechanism 7 is provided on one side of the laminating roller 4. The top scraping mechanism 7 includes support brackets 71 fixedly installed on both sides of the top of the base 1. A limit plate 72 is fixedly installed on one side of the two support brackets 71. The limit plate 72 is located in the middle of the two fabrics 3. The support bracket 71 is used to make the limit plate 72 located in the middle of the two fabrics 3.

[0044] like Figure 7 As shown, top pressure plates 73 are slidably installed on the upper and lower sides of the limit plate 72, and the two top pressure plates 73 are arranged in a vertical state. The outer walls of the two top pressure plates 73 are fixedly installed with scraper strips 74, and the outer walls of the scraper strips 74 are in contact with the outer walls of the fabric 3, and the scraper strips 74 and the outer walls of the fabric 3 are arranged perpendicular to each other. The outer walls of the two top pressure plates 73 are fixedly installed with multiple limit springs 75, and then, under the support of multiple limit springs 75, the top pressure plates 73 on the upper and lower sides of the limit plate 72 are forced to drive the scraper strips 74 close to and squeeze the outer walls of the two fabrics 3. Multiple limit springs 75 are fixedly installed on the inner walls of the limit plate 72, so that the position where the two fabrics 3 are close to each other for bonding can be swept and cleaned before bonding, so as to avoid debris remaining on the bonding side of the double-layer fabric 3 and affecting the bonding effect.

[0045] During specific implementation, the support bracket 71 is used to position the limit plate 72 between the two fabrics 3, and then, under the support of multiple limit springs 75, the top pressure plates 73 on the upper and lower sides of the limit plate 72 are forced to drive the scraper 74 close to the outer walls of the two fabrics 3, so that the position where the two fabrics 3 are close to each other for bonding is scraped and cleaned before bonding, avoiding the presence of debris on the bonding side of the double-layer fabric 3 that affects the bonding effect.

[0046] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships.
