Description

Technical Field

[0001] This invention relates to the technical field of flattening and shaping fabrics, and more particularly to a low-tension fabric feeding device for a flattening and stentering machine. Background Technology

[0002] Fabric setting and smoothing technology has undergone significant development in the textile industry, from early manual operations to modern automated equipment, greatly improving production efficiency and product quality. Traditional setting methods rely on steam and temperature treatment, which, while effective, require a high level of skill from operators. With technological advancements, advanced setting equipment such as heat setting machines and ultrasonic setting machines have become increasingly popular. These devices can achieve efficient setting in a shorter time, improving the smoothness and stability of the fabric. The application of intelligent control systems further optimizes the setting effect.

[0003] Existing fabric setting equipment still has some significant shortcomings in actual use. First, the equipment may cause excessive stress on the fabric during the setting process, especially under high tension. This can easily cause the fabric surface to be stretched and unable to shrink back, thereby damaging the fabric's smoothness and causing wrinkles, which affects the appearance quality of the fabric. This can cause huge losses, especially for high-end fabrics. The equipment's speed in adjusting tension is often delayed, failing to respond to changes in the fabric in a timely manner, further increasing the risk of irreversible damage to the fabric. Such damage not only affects the service life of the fabric but may also lead to economic losses for enterprises, failing to meet actual needs. Summary of the Invention

[0004] This invention discloses a low-tension fabric feeding device for a flattening and stentering machine, which aims to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-tension fabric feeding device for a flattening and stentering machine includes a machine body, a mounting frame fixedly connected to one side of the machine body, a finished fabric being provided at one end of the mounting frame, and multiple auxiliary rollers rotatably connected to the inner sides of the machine body, the mounting shell, and the mounting frame, respectively.

[0007] A feeding mechanism is installed on the inner side of the mounting frame, which is used to tighten the finished fabric on the inner side of the mounting frame;

[0008] The bottom of the machine body is provided with a mounting shell, and a fine-tuning mechanism is installed on one side of the bottom of the mounting shell. The fine-tuning mechanism is used to fine-tune the tension on the finished fabric. The fine-tuning mechanism includes a rotating plate rotatably connected to one side of the mounting shell, a cylinder rotatably connected to the bottom edge of the rotating plate, and an adjusting roller provided on one side of the cylinder.

[0009] The adjusting roller is equipped with a quick adjustment mechanism, which is used to quickly adjust the tension on the finished fabric.

[0010] A compression mechanism is installed on the top of the mounting housing, which is used to maintain the stability of the finished fabric.

[0011] A coarse adjustment mechanism is installed on the top of the other side of the machine body. The coarse adjustment mechanism is used to roughly adjust the tension on the finished fabric.

[0012] The feeding mechanism includes a third motor fixedly connected to the outside of the mounting frame. One end of the output shaft of the third motor is fixedly connected to a tension plate, and a tension rod is fixedly connected to one side of the tension plate. A tension roller is rotatably connected to the inner side of the mounting frame near the machine body. An intermediate roller is rotatably connected to the inner side of the mounting frame near the tension plate. The finished fabric contacts the tension rod, tension plate, and tension roller in sequence.

[0013] In a preferred embodiment, the quick adjustment mechanism includes a rotating shaft rotatably connected to one side of a rotating plate, a mounting plate fixedly connected to one end of the rotating shaft, a rotating ring provided on one side of the mounting plate, a fixed ring fixedly connected to one side of the rotating plate near the rotating shaft, and two electrode rings provided on one side of the rotating ring, with one side of the electrode rings rotatably connected to the rotating ring.

[0014] A fixing rod is fixedly connected to one side of the mounting plate. One end of the fixing rod is fixedly connected to the adjusting roller. An adjusting motor is fixedly connected inside the adjusting roller. Threaded rods are fixedly connected to both ends of the output shaft of the adjusting motor. An adjusting plug is threaded to one end of each threaded rod. The surface of the adjusting plug has multiple moving grooves, and one end of the adjusting plug has an internal thread. Multiple elastic plates are fixedly connected to both ends of the adjusting roller. A roller is rotatably connected to one end of each elastic plate. An elastic sleeve is fitted onto the outer wall of the adjusting roller, and multiple pressure sensors are provided on the upper surface of the elastic sleeve.

[0015] On the other side of the mounting plate, near the roller, there are multiple sliding grooves. The roller slides inside the sliding grooves. The end of the elastic plate near the roller naturally bends towards the fixed rod. The rotating ring is electrically connected to the adjusting motor.

[0016] The extrusion mechanism includes a conveying roller and a reversing roller rotatably connected to the inner side of the top of the mounting shell. A second motor is fixedly connected to one side of the top of the mounting shell. A first pulley is fixedly connected to one end of the output shaft of the second motor, and a second pulley is fixedly connected to one end of the conveying roller.

[0017] A belt is provided between the first pulley and the second pulley. A first extrusion roller and a second extrusion roller are rotatably connected to the other side of the top of the mounting shell. A first transmission wheel is provided at one end of the first extrusion roller. A first motor is fixedly connected to the outside of the mounting shell. A transmission box is provided at the bottom of the first motor. A driving bevel gear and a driven bevel gear are rotatably connected inside the transmission box.

[0018] The driving bevel gear is fixedly connected to one end of the output shaft of the first motor, and a second transmission wheel is provided on one side of the driven bevel gear. A transmission chain is provided between the first transmission wheel and the second transmission wheel.

[0019] In a preferred embodiment, the coarse adjustment mechanism includes a mounting plate fixedly connected to the top of the other side of the machine body, a fourth motor fixedly connected to one side of the mounting plate, and an adjustment disc fixedly connected to one end of the output shaft of the fourth motor.

[0020] Two friction rollers are rotatably connected to one side of the adjusting disc, and winding rollers are rotatably connected to both sides of the mounting plate.

[0021] As can be seen from the above, the low-tension fabric feeding device for a flattening and stentering machine provided by the present invention has the following technical effects.

[0022] Firstly, by adjusting the motor to drive the two threaded rods to rotate, the two adjusting plugs are moved closer to the motor. This causes the adjusting plugs to move away from the end of the elastic plate with the roller. In its natural state, one end of the elastic plate is close to the fixed rod, and the elastic plate drives the roller to slide inside the groove. This reduces the diameter of both ends of the elastic sleeve while keeping the middle diameter unchanged. By adjusting the motor to move the adjusting plugs, the pressure between the finished fabric and the elastic sleeve is immediately changed, quickly reducing the stress on both sides of the finished fabric and preventing unevenness caused by excessive stress on the edges of the finished fabric.

[0023] Secondly, if the pressure sensor on the surface of the elastic sleeve detects excessive pressure, it indicates that the tension on the finished fabric is too high. The fourth motor drives the two friction rollers to rotate clockwise, which significantly tightens the other end of the finished fabric, thus tightening the finished fabric between the first extrusion roller and the friction roller. Then, the cylinder drives the rotating plate to rotate counterclockwise, which precisely reduces the tension on the finished fabric between the first extrusion roller and the adjusting roller, thus achieving the effect of accurately adjusting the tension on the finished fabric.

[0024] Thirdly: The driven bevel gear is driven by the first motor to rotate, which in turn drives the first extrusion roller to rotate through the first and second transmission wheels, continuously conveying the finished fabric forward. When the tension on the finished fabric changes, the first and second extrusion rollers stabilize the position of the finished fabric. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Reference Figure 1 — Figure 9 A low-tension fabric feeding device for a flattening and stentering machine includes a machine body 1, a mounting frame 7 fixedly connected to one side of the machine body 1, a finished fabric 10 disposed at one end of the mounting frame 7, and multiple auxiliary rollers 11 rotatably connected to the inner sides of the machine body 1, the mounting shell 3 and the mounting frame 7 respectively.

[0037] A feeding mechanism is installed on the inner side of the mounting frame 7. The feeding mechanism is used to tighten the finished fabric 10 on the inner side of the mounting frame 7.

[0038] The bottom of the machine body 1 is provided with a mounting shell 3. A fine adjustment mechanism is installed on one side of the bottom of the mounting shell 3. The fine adjustment mechanism is used to fine adjust the tension on the finished fabric 10. The fine adjustment mechanism includes a rotating plate 13 rotatably connected to one side of the mounting shell 3. A cylinder 14 is rotatably connected to the bottom edge of the rotating plate 13. An adjusting roller 12 is provided on one side of the cylinder 14.

[0039] The adjusting roller 12 is equipped with a quick adjustment mechanism, which is used to quickly adjust the tension on the finished fabric 10.

[0040] An extrusion mechanism is installed on the top of the mounting housing 3. The extrusion mechanism is used to keep the finished fabric 10 stable.

[0041] A coarse adjustment mechanism is installed on the top of the other side of the machine body 1. The coarse adjustment mechanism is used to roughly adjust the tension on the finished fabric 10.

[0042] The feeding mechanism includes a third motor fixedly connected to the outside of the mounting frame 7. One end of the output shaft of the third motor is fixedly connected to a tension plate 21. A tension rod 22 is fixedly connected to one side of the tension plate 21. A tension roller 20 is rotatably connected to the inner side of the mounting frame 7 near the machine body 1. An intermediate roller 24 is rotatably connected to the inner side of the mounting frame 7 near the tension plate 21. The finished fabric 10 contacts the tension rod 22, the tension plate 21 and the tension roller 20 in sequence.

[0043] In this embodiment, the working principle is as follows: When in use, the finished fabric 10 passes through the tensioning rod 22, the tensioning plate 21 and the tensioning roller 20 in sequence. When the finished fabric 10 enters the feeding mechanism, the third motor drives the tensioning plate 21 and the tensioning rod 22 to rotate. The tensioning rod 22 is used to tighten the finished fabric 10, so that the finished fabric 10 is kept in a taut state when it is fed, which can prevent the finished fabric 10 from loosening.

[0044] Reference Figure 1 , Figure 7 , Figure 8 and Figure 9 In a preferred embodiment, the quick adjustment mechanism includes a rotating shaft 35 rotatably connected to one side of the rotating plate 13. One end of the rotating shaft 35 is fixedly connected to a mounting plate 27. A rotating ring 36 is provided on one side of the mounting plate 27. A fixing ring 34 is fixedly connected to one side of the rotating plate 13 near the rotating shaft 35. Two electrode rings are provided on one side of the rotating ring 36, and one side of the electrode rings is rotatably connected to the rotating ring 36.

[0045] A fixing rod 29 is fixedly connected to one side of the mounting plate 27. One end of the fixing rod 29 is fixedly connected to the adjusting roller 12. An adjusting motor 25 is fixedly connected inside the adjusting roller 12. Threaded rods 30 are fixedly connected to both ends of the output shaft of the adjusting motor 25. An adjusting plug 28 is threadedly connected to one end of the threaded rod 30. Multiple moving grooves 37 are provided on the surface of the adjusting plug 28. An internal thread 38 is provided at one end of the adjusting plug 28. Multiple elastic plates 26 are fixedly connected to both ends of the adjusting roller 12. A roller 32 is rotatably connected to one end of each elastic plate 26. An elastic sleeve 31 is sleeved on the outer wall of the adjusting roller 12 and the elastic plate 26. Multiple pressure sensors are provided on the upper surface of the elastic sleeve 31.

[0046] On the other side of the mounting plate 27, near the roller 32, there are multiple sliding grooves 33. The roller 32 slides inside the sliding grooves 33. The end of the elastic plate 26 near the roller 32 naturally bends towards the fixed rod 29. The rotating ring 36 is electrically connected to the adjusting motor 25.

[0047] The extrusion mechanism includes a conveying roller 15 and a reversing roller 16 rotatably connected to the inner side of the top of the mounting shell 3. A second motor 6 is fixedly connected to one side of the top of the mounting shell 3. A first pulley is fixedly connected to one end of the output shaft of the second motor 6, and a second pulley is fixedly connected to one end of the conveying roller 15.

[0048] A belt 19 is provided between the first pulley and the first pulley. A first extrusion roller 2 and a second extrusion roller are rotatably connected to the other side of the top of the mounting shell 3. A first transmission wheel 4 is provided at one end of the first extrusion roller 2. A first motor 5 is fixedly connected to the outside of the mounting shell 3. A transmission box is provided at the bottom of the first motor 5. A driving bevel gear and a driven bevel gear are rotatably connected inside the transmission box.

[0049] The driving bevel gear is fixedly connected to one end of the output shaft of the first motor 5, and a second transmission wheel 23 is provided on one side of the driven bevel gear. A transmission chain is provided between the first transmission wheel 4 and the second transmission wheel 23.

[0050] In this embodiment, since the response speed of cylinder 14 is related to the cylinder diameter and stroke length of cylinder 14, the response speed of cylinder 14 is one-tenth of a second. Before cylinder 14 drives rotating plate 13 to rotate, thereby reducing the tension on finished fabric 10, the two threaded rods 30 are driven to rotate by adjusting motor 25, thereby driving the two adjusting plugs 28 to move towards adjusting motor 25, so that the adjusting plugs 28 are away from the end of elastic sheet 26 with roller 32.

[0051] Furthermore, in its natural state, one end of the elastic piece 26 is close to the fixed rod 29. The elastic piece 26 drives the roller 32 to slide inside the groove 33, thereby reducing the diameter of both ends of the elastic sleeve 31 while keeping the middle diameter of the elastic sleeve 31 unchanged. By adjusting the motor 25 to move the adjusting plug 28, the pressure between the finished fabric 10 and the elastic sleeve 31 is immediately changed, which quickly reduces the stress on both sides of the finished fabric 10 and prevents the edges of the finished fabric 10 from becoming uneven due to excessive stress.

[0052] Furthermore, the first motor 5 drives the driven bevel gear to rotate, which in turn drives the first extrusion roller 2 to rotate through the first transmission wheel 4 and the second transmission wheel 23, continuously conveying the finished fabric 10 forward. When the tension on the finished fabric 10 changes, the first extrusion roller 2 and the second extrusion roller play a role in stabilizing the position of the finished fabric 10.

[0053] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the coarse adjustment mechanism includes a mounting plate 8 fixedly connected to the top of the other side of the body 1, a fourth motor fixedly connected to one side of the mounting plate 8, and an adjustment disc 18 fixedly connected to one end of the output shaft of the fourth motor.

[0054] Two friction rollers 17 are rotatably connected to one side of the adjusting plate 18, and winding rollers 9 are rotatably connected to both sides of the mounting plate 8.

[0055] In this embodiment, the pressure sensor on the upper surface of the elastic sleeve 31 detects excessive pressure, indicating that the tension on the finished fabric 10 is too high. The fourth motor drives the two friction rollers 17 to rotate clockwise, significantly tightening the other end of the finished fabric 10, thus tightening the finished fabric 10 between the first extrusion roller 2 and the friction roller 17. Then, the cylinder 14 drives the rotating plate 13 to rotate counterclockwise, precisely reducing the tension on the finished fabric 10 between the first extrusion roller 2 and the adjusting roller 12, thereby achieving the effect of accurately adjusting the tension on the finished fabric 10.

[0056] Working principle: During use, the finished fabric 10 passes sequentially through the tensioning rod 22, tensioning plate 21, and tensioning roller 20, then through multiple auxiliary rollers 11. The finished fabric 10 then passes through the adjusting roller 12, conveying roller 15, and reversing roller 16, followed by the first and second compression rollers. Finally, it passes through two adjusting discs 18 and winding roller 9. The second motor 6 drives the first and second pulleys to rotate, thereby driving the conveying roller 15 to rotate. The first motor 5 drives the driven bevel gear to rotate, which in turn drives the first compression roller 2 to rotate via the first transmission wheel 4 and the second transmission wheel 23, continuously pushing the finished fabric 10 forward. During conveying, the first and second extrusion rollers stabilize the position of the finished fabric 10 as the tension changes. When the finished fabric 10 enters the feeding mechanism, the third motor drives the tension plate 21 and tension rod 22 to rotate, using the tension rod 22 to tighten the finished fabric 10, keeping it taut during feeding and preventing it from loosening. If the pressure sensor on the upper surface of the elastic sleeve 31 is too high vertically, it indicates that the tension on the finished fabric 10 is too great. In this case, the fourth motor drives the two friction rollers 17 to rotate clockwise, significantly tightening the other end of the finished fabric 10. The finished fabric 10 between the first extrusion roller 2 and the friction roller 17 is tightened. Then, the cylinder 14 drives the rotating plate 13 to rotate counterclockwise, precisely reducing the tension on the finished fabric 10 between the first extrusion roller 2 and the adjusting roller 12. This achieves the effect of accurately adjusting the tension on the finished fabric 10. Since the response speed of the cylinder 14 is related to the cylinder diameter and stroke length, the response speed of the cylinder 14 is one-tenth of a second. Before the cylinder 14 drives the rotating plate 13 to rotate, thereby reducing the tension on the finished fabric 10, the adjusting motor 25 drives the two threaded rods 30 to rotate, thereby driving the two adjusting plugs 28. The adjusting plug 28 moves closer to the adjusting motor 25, thus moving the adjusting plug 28 away from the end of the elastic plate 26 with the roller 32. In its natural state, one end of the elastic plate 26 is close to the fixed rod 29. The elastic plate 26 drives the roller 32 to slide inside the groove 33, thereby reducing the diameter of both ends of the elastic sleeve 31 while keeping the middle diameter unchanged. By moving the adjusting plug 28 through the adjusting motor 25, the pressure between the finished fabric 10 and the elastic sleeve 31 is immediately changed, quickly reducing the stress on both sides of the finished fabric 10 and preventing the edges of the finished fabric 10 from becoming uneven due to excessive stress.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
