Description

Technical Field

[0001] This invention belongs to the field of fabric production and processing technology, and specifically relates to a conveying device and method for fabric stretching and setting. Background Technology

[0002] Fabric is a flat, soft sheet of material made by crossing, knotting, and connecting small, flexible threads. Woven fabric is made of yarns with interlacing relationships. Knitted fabric is made of yarns with knotting relationships. Nonwoven fabric is made of yarns with connecting relationships. A third type of fabric is made of yarns with interlacing / knotting relationships.

[0003] After weaving, the fabric undergoes a stretching and setting process. After stretching and setting, the fabric needs to be wound up or proceed to the next step. Regardless of the subsequent operation, a conveying device is required to transport the fabric from the stretching machine. Existing conveying devices often only have simple conveyor rollers or conveyors composed of multiple conveyor rollers. These machines have a simple and straightforward structure, consisting of only conveyor rollers and possessing only a simple conveying function. However, due to the special nature of the stretched and set fabric, it is necessary to maintain its shape and prevent deformation during subsequent transport. Therefore, some conveying devices add adjustable pressure rollers on top of the conveyor rollers for auxiliary transport. Firstly, this ensures that the fabric does not slip between the conveyor rollers, and secondly, the pressure rollers prevent the stretched and set fabric from reverting to its original shape, thus ensuring its stability after stretching to a certain extent.

[0004] However, existing pressure roller adjustment mechanisms are all adjusted by simple screws, or by adding some support springs or other buffer mechanisms to prevent the pressure roller from excessively squeezing the fabric. But these only assist in the pressure change of the pressure roller relative to the conveyor roller, while ignoring the variability of the pressure roller itself. This makes such conveying devices only suitable for conveying a single type or a few simple types of fabrics, and their effectiveness is very limited.

[0005] To address this issue, we propose a conveying device for fabric stretching and setting to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a conveying device for fabric stretching and setting, which can make the adjustment range and precision between the pressure roller and the conveying roller wider and finer according to different installation positions of the tightening mechanism, and can handle the conveying operation of different fabrics, greatly improving the practicality of the invention.

[0019] The fabric stretching and setting conveying device of the present invention allows the stretched and set fabric to pass through an anti-wrinkle mechanism on one side and enter between the conveying roller and the pressure roller. At this time, the tightening mechanism can be adjusted to adjust the distance between the arc plate and the support frame. The conveying roller rotates fixedly relative to the support frame, while the pressure roller rotates fixedly relative to the arc plate. Therefore, the tightening mechanism can adjust the distance between the pressure roller and the conveying roller, so as to achieve a better conveying effect when the conveying roller drives the fabric.

[0020] The anti-wrinkle mechanism of the present invention can perform edge unfolding operation on the fabric on the inlet and outlet conveyor rollers, so that the edge of the fabric is flatter when it enters and exits the conveyor rollers, avoiding unnecessary creases during subsequent winding, and also facilitating subsequent winding.

[0021] The tightening mechanism of this invention is mainly adjusted through connecting components. During actual installation, the connecting components can be adjusted to different initial positions by installing clamps at different positions on the adjusting screw sleeve. As shown in the figure, if three annular grooves are opened on the adjusting screw sleeve, the initial distance between the two adjusting screw sleeves can have six different variations depending on the position of the clamps when the two connecting components are installed. This makes the adjustment range and precision between the pressure roller and the conveying roller wider and finer, which can handle the conveying operation of different fabrics and greatly improves the practicality of this invention.

[0036] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0037] Example 1

[0038] like Figure 1As shown, a conveying device for fabric stretching and setting includes a conveyor roller 1 for conveying the stretched and set fabric, and a pressure roller 6 for pressing the fabric on the conveyor roller 1. Support frames 2 are provided at both ends of the conveyor roller 1. A power source for driving the conveyor roller 1 is located inside the support frame 2. The conveyor roller 1 is connected to the power source via a drive shaft 3. A tensioning mechanism 4 is provided at the top of the support frame 2. An arc-shaped plate 5 is installed on the side of the tensioning mechanism 4 facing the conveyor roller 1. The arc-shaped plate 5 is arranged along the length of the tensioning mechanism 4 and is perpendicular to the conveyor roller 1. First bearing seats 7 are fixedly installed at both ends of the side of the arc-shaped plate 5 facing the conveyor roller 1. Assembly shafts 8 are installed at both ends of the pressure roller 6, with the assembly shafts 8 located away from the pressure roller 6. One end is installed in the first bearing seat 7. The adjusting mechanism 4 can adjust the distance between the arc plate 5 and the support frame 2. The conveying roller 1 is fixed and rotates relative to the support frame 2, while the pressure roller 6 is fixed and rotates relative to the arc plate 5. Therefore, the function of the adjusting mechanism 4 is to adjust the distance between the pressure roller 6 and the conveying roller 1, so that the conveying roller 1 can have a better conveying effect when it drives the fabric. The support frame 2 is also equipped with anti-wrinkle mechanism 9 on both sides along its length direction. The anti-wrinkle mechanism 9 can perform edge unfolding operation on the fabric entering and exiting the conveying roller 1, so that the edge of the fabric is flatter when entering and exiting the conveying roller 1, avoiding unnecessary creases during subsequent winding, and also providing convenience for subsequent winding.

[0039] like Figure 2 As shown, to improve the stability of the support frame 2, in this embodiment, preferably, the support frame 2 includes a base plate 201, with a fixing sleeve 202 located directly above the base plate 201. The fixing sleeve 202 is fixedly mounted on the base plate 201 via a support rod 203. A support plate 204 is fixedly mounted on the top of the fixing sleeve 202. The support plate 204 is parallel to the base plate 201 and is arranged along the length of the base plate 201. The bottom of the support plate 204 is also connected to the outer wall of the fixing sleeve 202 via a reinforcing rod 205. (Adjustment mechanism) 4. A connecting frame 206 is also fixedly installed on the outer wall of the fixed jacket 202, and the anti-wrinkle mechanism 9 is installed at the end of the connecting frame 206 away from the fixed jacket 202. The fixed jacket 202 is used to install power devices such as power motors. The drive shaft 3 at the end of the conveyor roller 1 is connected to the power device inside the fixed jacket 202 to provide power to the conveyor roller 1. In order to protect the power device inside the fixed jacket 202, a sealing plate 207 is detached and installed at the end of the fixed jacket 202 away from the conveyor roller 1.

[0040] like Figure 3As shown, in order to make the adjustment between the pressure roller 6 and the conveying roller 1 more precise and stable, in this embodiment, preferably, the tightening mechanism 4 includes an adjusting plate 41. The adjusting plate 41 is located directly above the support plate 204. Mounting sleeves 42 are fixedly installed at the bottom of both ends of the adjusting plate 41 along its length. The two ends of the side of the arc-shaped plate 5 facing the mounting sleeves 42 are fixedly connected to the mounting sleeves 42 by fixing rods. The bottom of the adjusting plate 41 is connected to the top of the support plate 204 through a support assembly 43. Stabilizing assemblies 44 are also installed on both sides of the top of the support plate 204. The stabilizing assemblies 44 are located directly below the mounting sleeves 42, and the mounting sleeves 42 are mounted on the stabilizing assemblies 44. The bottom center of the adjusting plate 41 and the support... Each support plate 204 has a connecting component 47 installed at its top center. The two connecting components 47 are connected relative to each other. An adjusting shaft 48 is provided through the center of the adjusting plate 41, and the bottom end of the adjusting shaft 48 is connected to the connecting component 47 installed on the adjusting plate 41. When the adjusting shaft 48 rotates, it can adjust the connecting component 47, so that the relative position between the two connecting components 47 changes. The two connecting components 47 are respectively installed on the adjusting plate 41 and the support plate 204. Therefore, the change in the position of the connecting component 47 is the change in the position between the adjusting plate 41 and the support plate 204, thereby changing the distance between the adjusting plate 41 and the support plate 204, and finally realizing the position adjustment of the pressure roller 6.

[0041] In order to make the mounting sleeve 42 more stable during lifting, in this embodiment, preferably, an extension block 45 is fixedly provided on the outer side wall of the mounting sleeve 42, a guide rod 46 is provided through the extension block 45, the bottom end of the guide rod 46 is fixedly installed on the top of the support plate 204 through a fixing seat 461, a stop block 462 is fixedly installed on the top end of the guide rod 46, and a limit groove 463 is provided on the side wall of the guide rod 46, and a limit block that cooperates with the limit groove 463 is provided inside the extension block 45.

[0042] like Figure 4-6 As shown, in order to enable the support assembly 43 to stably support the adjustment plate 41 and have an automatic return function, in this embodiment, preferably, the support assembly 43 includes a support column 431 with telescopic function and automatic return function. Positioning plates 432 are installed at both ends of the support column 431. A positioning groove 4321 is opened at the center of the end face of the positioning plate 432 away from the support column 431. Positioning protrusions 208 are fixedly installed on the top of the base plate 201 and the bottom of the adjustment plate 41. The positioning protrusions 208 are adapted to the positioning grooves 4321.

[0043] In one embodiment of the present invention, the support column 431 includes a fixed sleeve 4311. A rod 4312 is inserted into the top end of the fixed sleeve 4311. A pressure plate 4313 is fixedly installed at the bottom end of the rod 4312. The pressure plate 4313 is slidably disposed within the fixed sleeve 4311. An annular sealing plate 4314 is also fitted around the outside of the rod 4312. The annular sealing plate 4314 is fixedly installed at the top end of the fixed sleeve 4311. A guide groove 4315 is formed on the inner sidewall of the fixed sleeve 4311. The guide groove 4315 is arranged along the length direction of the rod 4312, and the pressure plate 4313... A guide block 4316 is fixedly installed on the side wall. The end of the guide block 4316 away from the pressure plate 4313 is slidably disposed in the guide groove 4315. A support spring 4317 is provided between the pressure plate 4313 and the positioning plate 432 located at the bottom of the fixed sleeve 4311. The support spring 4317 can support the pressure plate 4313. When the positioning plate 432 at the top of the support column 431 is subjected to the pressure of the adjusting plate 41, the support spring 4317 can be compressed and deformed, thereby changing the length of the support column 431. When the adjusting plate 41 is adjusted in the opposite direction, the support spring 4317 will automatically reset.

[0044] like Figure 7 As shown, in order to ensure that the mounting sleeve 42 can provide sufficient stability when the adjusting plate 41 is adjusted, in this embodiment, preferably, the stabilizing component 44 includes a mounting base 441. The mounting base 441 is fixedly installed on both sides of the top of the support plate 204. An arc-shaped support plate 442 is provided directly above the mounting base 441. A spring rod 443 is movably installed on the bottom side wall of the arc-shaped support plate 442. One end of the spring rod 443 connected to the arc-shaped support plate 442 can rotate around the connection point. A strip groove 444 is provided on the mounting base 441. The end of the spring rod 443 away from the arc-shaped support plate 442 is slidably connected to the strip groove 444. When the adjusting plate 41 and the support plate 204 are adjusted, the mounting sleeve 42 will also move synchronously with the adjusting plate 41. At this time, the mounting sleeve 42 will drive the spring rod 443 to move through the arc-shaped support plate 442. The end of the spring rod 443 away from the arc-shaped support plate 442 will slide on the mounting base 441 through the strip groove 444. During this process, the movement direction of the arc-shaped support plate 442 and the sliding direction of the spring rod 443 are both driven movements. All states are derived from the adjustment position of the adjusting plate 41. Therefore, when the adjusting plate 41 is not adjusted, the spring rod 443 can support the arc-shaped support plate 442, play a stabilizing role in movement, and give the mounting sleeve 42 a certain buffering performance.

[0045] like Figure 8-10As shown, in order to enable the connecting assembly 47 to more precisely connect and stabilize the adjusting plate 41 and the support plate 204, in this embodiment, preferably, the connecting assembly 47 includes a mounting plate 471. A crash barrier 472 is fixedly mounted at the center of one end face of the mounting plate 471. Hinges 473 are symmetrically mounted on both sides of the end face of the mounting plate 471 where the crash barrier 472 is mounted. A connecting rod 474 is mounted on the hinge 473. A clamp 475 is connected to the end of the connecting rod 474 away from the hinge 473. An adjusting sleeve 476 is internally fitted and positioned opposite the anti-collision seat 472. An adjusting screw 477 is installed inside the adjusting sleeve 476. To improve the stable movement of the adjusting sleeve 476 relative to the anti-collision seat 472, a limiting hole 478 is provided inside the adjusting sleeve 476. The limiting hole 478 is positioned along the length of the adjusting screw 477. A limiting rod 479 is installed at the end of the anti-collision seat 472 facing the adjusting sleeve 476. The end of the limiting rod 479 away from the anti-collision seat 472 is also fitted with a limiting rod 479. The ends are inserted into the limiting holes 478. Two connecting components 47 are respectively installed on the center of the opposite side of the adjusting plate 41 and the support plate 204. Then, the adjusting screws 477 are adjusted, and the two adjusting screws 477 are connected by a coupling. When subjected to external force, the two adjusting screws 477 can rotate synchronously. Because the two adjusting screws 477 are arranged oppositely, their external threads are also opposite, and the directions of the threads will be opposite. When the adjusting screws 477 are rotated by external force, the adjusting screws 477 rotate synchronously. The adjusting screw sleeve 476 will not rotate with the adjusting screw 477 due to the action of the limiting rod 479 and the limiting hole 478. At this time, the distance between the two adjusting screw sleeves 476 will change. The adjusting screw sleeve 476 will then drive the connecting rod 474 to move synchronously through the external clamp 475. The other end of the connecting rod 474 is mounted on the mounting plate 471 through the hinge seat 473. Therefore, when the distance between the two adjusting screw sleeves 476 changes, the distance between the adjusting plate 41 and the support plate 204 will be adjusted synchronously.

[0046] To facilitate the adjustment of the adjusting screw 477 by external force, in this embodiment, preferably, an outer sleeve 49 is provided through the center of the adjusting plate 41, and an adjusting shaft 48 is provided inside the outer sleeve 49. A first through hole 4711 is provided at the center of the mounting plate 471, and a second through hole 4721 is provided at the center of the anti-collision seat 472. The first through hole 4711 and the second through hole 4721 are connected and positioned opposite the outer sleeve 49. The bottom end of the adjusting shaft 48 passes sequentially through the first through hole 4711 on the mounting plate 471 and the second through hole 4721 on the anti-collision seat 472, and is connected to the top shaft of the adjusting screw 477. Rotating the adjusting shaft 48 will drive the adjusting screw 477 to rotate.

[0047] In order to improve the adjustment range of the connecting component 47 in actual operation, in this embodiment, preferably, the outer wall of the adjusting screw sleeve 476 is provided with an annular groove 4761 arranged vertically, and the inner side wall of the clamp 475 is integrally provided with an annular protrusion 4751 that matches the annular groove 4761. The clamp 475 is composed of two semi-circular plates, the annular protrusion 4751 is provided on the inner side wall of the semi-circular plates, and the two ends of the semi-circular plates are welded with connecting ears 4752 for connecting with the end of the connecting rod 474.

[0048] like Figure 11-12 As shown, in order to enable the anti-wrinkle mechanism 9 to perform anti-wrinkle operation on the sides of the fabric, in this embodiment, preferably, the anti-wrinkle mechanism 9 includes a mounting frame 91. The mounting frame 91 is installed at the end of the connecting frame 206 away from the fixed outer sleeve 202. One side of the mounting frame 91 is provided with smoothing rollers 92 arranged vertically opposite each other. The end of the smoothing rollers 92 facing the mounting frame 91 is rotatably mounted with a mounting rod 94 through a mounting bearing 93. The end of the mounting rod 94 away from the mounting bearing 93 is fixedly installed in the mounting frame 91. The smoothing rollers 92 are arranged directly opposite the edge of the conveyor roller 1. Regardless of which side of the conveyor roller 1 the stretched and shaped fabric is conveyed from, the edges of the fabric will pass between the oppositely arranged smoothing rollers 92, which can ensure to a certain extent that the edges of the fabric will not wrinkle.

[0049] To enable the anti-wrinkle mechanism 9 to have a certain degree of adjustability relative to the conveyor roller 1, in this embodiment, preferably, the mounting frame 91 includes an outer frame 911, with an inner mounting hole 912 at the center of the outer frame 911. The inner mounting hole 912 contains symmetrically arranged adjusting blocks 913. The end of the mounting rod 94 away from the mounting bearing 93 is connected to the adjusting block 913. The two adjusting blocks 913 are connected by an elastic connector 914. An adjusting screw 915 is rotatably mounted at the center of the end of the adjusting block 913 away from the elastic connector 914 via a second bearing seat 917. The end of the adjusting screw 915 away from the second bearing seat 917 passes through the outer frame 911. A fixing sleeve 916 is also installed inside the outer frame 911, and the adjusting screw 915 is threadedly assembled with the fixing sleeve 916. Rotating the adjusting screw 915 changes its position through the fixing screw sleeve 916, which in turn drives the adjusting block 913 to move within the inner mounting hole 912. The adjusting block 913 then simultaneously adjusts the position of the mounting rod 94, thereby achieving the position adjustment of the smoothing roller 92. The position of the smoothing roller 92 can be adjusted according to the actual situation.

[0050] In order to make the adjustment block 913 more stable, in this embodiment, preferably, a limiting groove 918 is provided on the side wall of the inner mounting hole 912. The limiting groove 918 is arranged along the length direction of the adjusting screw 915. A limiting slider 919 is fixedly installed on the outer side wall of the adjustment block 913. The limiting slider 919 is slidably disposed in the limiting groove 918.

[0051] The working principle of this invention is as follows: After being stretched and shaped, the fabric can enter between the conveyor roller 1 and the pressure roller 6 through the anti-wrinkle mechanism 9 on one side. At this time, the tensioning mechanism 4 can be adjusted. The tensioning mechanism 4 can adjust the distance between the arc plate 5 and the support frame 2. The conveyor roller 1 rotates fixedly relative to the support frame 2, while the pressure roller 6 rotates fixedly relative to the arc plate 5. Therefore, the tensioning mechanism 4 can adjust the distance between the pressure roller 6 and the conveyor roller 1, so that the conveyor roller 1 can have a better conveying effect when it drives the fabric. The anti-wrinkle mechanism 9 can perform edge unfolding operation on the fabric entering and exiting the conveyor roller 1, so that the edge of the fabric is flatter when entering and exiting the conveyor roller 1, avoiding unnecessary creases during subsequent winding, and also providing convenience for subsequent winding.

[0052] The tightening mechanism 4 is mainly adjusted through the connecting component 47. During actual installation, the connecting component 47 can be adjusted to different initial positions by installing the clamp 475 at different positions on the adjusting sleeve 476. For example... Figure 8 As shown, three annular grooves 4761 are provided on the adjusting screw sleeve 476. When the two connecting components 47 are installed opposite each other, the initial distance between the two adjusting screw sleeves 476 can have six different variations depending on the position of the clamp 475. This makes the adjustment range and precision between the pressure roller 6 and the conveying roller 1 wider and finer, and can handle the conveying operation of different fabrics, greatly improving the practicality of the invention.

[0053] Example 2

[0054] This embodiment is a further improvement on embodiment 1, and its only difference from embodiment 1 is:

[0055] Please see Figure 6The support spring 4317 is no longer used. On the opposite sides of the pressure plate 4313 and the positioning plate 432, opposing magnet blocks 4318 are fixedly installed via fixing rings 4319, and the magnetic poles on the opposite sides of the opposing magnet blocks 4318 are the same. Similarly, when the positioning plate 432 at the top of the support column 431 is subjected to pressure from the adjusting plate 41, the two magnet blocks 4318 will move closer to each other. The repulsion between like poles provides support. When the adjusting plate 41 is adjusted in the opposite direction, the two magnet blocks 4318 will move away from each other due to the repulsion between like poles, causing the magnet blocks 4318 to automatically reset. Compared to conventional springs or other elastic reset components, this method results in less wear and tear and greater durability.

[0056] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
