Description

A cloth feeding device for a long ring steaming machine Technical Field

[0001] This application relates to the field of long ring steaming machines, and more particularly to a cloth feeding device for a long ring steaming machine. Background Technology

[0002] The long-ring steaming machine is a key piece of equipment used for color fixing and finishing of printed fabrics. It uses steam or hot air to allow dyes to penetrate the fibers and stabilize the color.

[0003] In related technologies, please refer to the utility model patent with announcement number CN202214616U, which discloses a fabric feeding device for a long ring steaming machine, including a fabric feeding roller system and a humidification system installed on the fabric feeding roller system; the humidification system includes a water spray plate connected to a liquid supply tank, a water pump installed between the liquid supply tank and the water spray plate, the water spray plate is located in front of the fabric in the fabric feeding roller system, and the nozzles of the water spray plate face the front of the fabric. By adding a humidification system to the fabric feeding roller system, the performance of the fabric treated by the long ring steaming machine can be improved.

[0004] Before entering the long-ring steamer, the fabric is stacked in the storage box, which easily causes wrinkles on the fabric. If it is directly sent into the long-ring steamer for steaming, the wrinkled parts are not easily penetrated, which significantly affects the uniformity of the steaming operation and the quality of the finished product, resulting in poor steaming treatment of the fabric. Summary of the Invention

[0005] To address the problem of poor fabric steaming results caused by wrinkles in the fabric, this application provides a fabric feeding device for a long-ring steaming machine.

[0006] The feeding device for a long-ring steaming machine provided in this application adopts the following technical solution:

[0007] A fabric feeding device for a long-ring steaming machine includes a fabric feeding frame disposed on one side of the fabric inlet of the long-ring steaming machine. The fabric feeding frame is provided with several parallel guide rollers. Along the fabric transport direction, the fabric feeding frame is sequentially provided with an expansion roller, a tensioning assembly, and a preheating assembly. The expansion roller is rotatably mounted on the fabric feeding frame and is parallel to the guide rollers. The tensioning assembly includes a first tensioning roller and a second tensioning roller rotatably mounted on the fabric feeding frame and parallel to each other. The preheating assembly includes a steam preheating hood disposed on the fabric feeding frame. Two sets of steam preheating hoods are disposed opposite each other on both sides of the fabric. The steam preheating hoods are connected to an external steam generator.

[0008] By adopting the above technical solution, the fabric is transported on the guide roller, expanded by the expansion roller, and then tensioned by the first tension roller and the second tension roller before entering the steam preheating hood. The steam from the steam preheating hoods on both sides preheats and flattens the fabric, reducing wrinkles and improving the steaming effect of the fabric in the long ring steamer.

[0009] Optionally, a rotating frame is rotatably mounted on the fabric feeding frame, and both ends of the first tension roller and the second tension roller are connected to the rotating frame. An adjusting component is provided on the fabric feeding frame to drive the rotating frame to rotate.

[0011] Optionally, the adjusting component includes a gear and a rack. The gear is rotatably mounted on the fabric feed frame and coaxially connected to the rotating frame. The rack is slidably mounted on the fabric feed frame and meshes with one side of the gear. The fabric feed frame is provided with a driving component for driving the rack to slide.

[0012] By adopting the above technical solution, the driving component drives the rack to slide, thereby driving the gear to rotate.

[0014] By adopting the above technical solution, the drive motor drives the lead screw to rotate, the lead screw drives the slider to slide and then drives the rack to move. The operation is convenient through the lead screw and slider drive, and the rotation of the rotating frame can be locked at the same time.

[0015] Optionally, a sliding groove is provided on the rotating frame along its length. An adjusting screw is rotatably mounted on the rotating frame at the sliding groove. Connecting blocks are provided at both ends of the first tension roller and both ends of the second tension roller. The connecting blocks are slidably mounted at the sliding groove of the rotating frame. The adjusting screw is provided with two opposite threads. The connecting blocks on both sides are threadedly connected to the adjusting screw at the two opposite threads.

[0016] By adopting the above technical solution, rotating the adjusting screw synchronously drives the connecting blocks on both sides to move, thereby driving the first tension roller and the second tension roller on both sides to move in opposite directions, adjusting the distance between the first tension roller and the second tension roller, which facilitates tension adaptation adjustment for different fabrics.

[0017] Optionally, a guide rod is slidably mounted on the connecting block, a spring is sleeved on the guide rod, a mounting plate is provided at one end of the guide rod, one end of the spring is connected to the mounting plate, and the two ends of the first tension roller and the second tension roller are rotatably connected to the mounting plate.

[0018] By adopting the above technical solution, when the fabric is subjected to the tension of the first tension roller and the second tension roller, the first tension roller and the second tension roller are pulled, causing the guide rod to slide. At this time, the spring is compressed, and the elastic spring presses against the fabric, reducing the probability of damaging the fabric.

[0019] Optionally, the steam preheating hood is provided with a plurality of heat spreaders, which are evenly spaced along the length of the steam preheating hood.

[0020] By adopting the above technical solution, the heat spreader plate can uniformly guide the steam sent out by the steam preheating hood, resulting in a better ironing effect on the fabric.

[0021] Optionally, flattening rollers are provided on the fabric feeding frame and on both sides of the steam preheating hood, and there are two flattening rollers that are distributed parallel to each other.

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a fabric feeding device for a long-ring steaming machine. Referring to Figures 1 and 2, it includes a fabric feeding frame 1, which is located on one side of the fabric inlet of the long-ring steaming machine. The fabric feeding frame 1 is provided with a plurality of parallel guide rollers 11, which are distributed along the width direction of the fabric feeding frame 1. The fabric feeding frame 1 is provided with an expansion roller 2, a tensioning assembly 3, and a preheating assembly in sequence along the fabric transport direction. The expansion roller 2 is rotatably mounted on the fabric feeding frame 1 and is distributed parallel to the guide rollers 11. The tensioning assembly 3 includes a first tensioning roller 31 and a second tensioning roller 32, which are rotatably mounted on the fabric feeding frame 1 and are distributed parallel to each other. The preheating assembly includes a steam preheating hood 4 provided on the fabric feeding frame 1. The steam preheating hood 4 is provided in two sets and is distributed opposite to each other on the upper and lower sides of the fabric. The steam preheating hood 4 is connected to an external steam generator through a steam pipe 41.

[0035] The fabric is transported on the guide roller 11, and after being expanded by the expansion roller 2, it is tensioned by the first tension roller 31 and the second tension roller 32. Then it enters the steam preheating hood 4, where the steam from both sides of the steam preheating hood 4 preheats and flattens the fabric, reducing wrinkles and improving the steaming effect of the fabric in the long ring steamer.

[0036] Referring to Figures 1 and 2, a rotating frame 12 is rotatably mounted on the fabric feed frame 1 at one side of the spreading roller 2. The rotation axis of the rotating frame 12 is consistent with the axis of the spreading roller 2. The rotating frame 12 is located at both ends of the first tensioning roller 31 and the second tensioning roller 32 along their length and is distributed relative to each other. Both ends of the first tensioning roller 31 and the second tensioning roller 32 are connected to the rotating frame 12 and are located on both sides of the axis of the rotating frame 12. An adjusting component 5 is provided on the fabric feed frame 1.

[0037] Referring to Figure 3, the adjusting component 5 includes a gear 51 and a rack 52. The gear 51 is rotatably mounted on the fabric feed frame 1 and is coaxially and fixedly connected to the rotating frame 12. The rack 52 is slidably mounted on the fabric feed frame 1 in the horizontal direction, and the rack 52 meshes with one side of the gear 51. A driving component 6 is provided on the fabric feed frame 1. The driving component 6 includes a drive motor 61 and a lead screw 62. The lead screw 62 is rotatably mounted on the fabric feed frame 1 in the horizontal direction. A slider 63 is slidably mounted on the fabric feed frame 1 in the horizontal length direction. The slider 63 is threadedly connected to the lead screw 62. The drive motor 61 is located on the fabric feed frame 1, and the lead screw 62 is connected to the output shaft of the drive motor 61.

[0038] The drive motor 61 drives the lead screw 62 to rotate, the lead screw 62 drives the slider 63 to slide, which in turn drives the rack 52 to move. The rack 52 slides, which in turn drives the gear 51 to rotate. The gear 51 drives the rotating frame 12 to rotate, which in turn drives the first tension roller 31 and the second tension roller 32 to rotate. The positions of the first tension roller 31 and the second tension roller 32 are adjusted, thereby adjusting the tension of the fabric. The tension of the fabric is uniform. The operation is convenient through the drive control of the lead screw 62 and the slider 63, and the rotation of the rotating frame 12 can be locked at the same time.

[0039] Referring to Figure 4, a groove 121 is provided on one of the opposing sides of the rotating frame 12 along its length. An adjusting screw 122 is rotatably mounted on the rotating frame 12 at the groove 121. The adjusting screw 122 is distributed along the length of the rotating frame 12. Connecting blocks 123 are provided at both ends of the first tension roller 31 and both ends of the second tension roller 32. The connecting blocks 123 are slidably mounted at the groove 121 of the rotating frame 12. The connecting blocks 123 on both sides slide in opposite directions. The adjusting screw 122 is provided with two opposite threads. The connecting blocks 123 on both sides are threadedly connected to the adjusting screw 122 at the two opposite threads. Rotating the adjusting screw 122 synchronously drives the connecting blocks 123 on both sides to move, thereby driving the first tension roller 31 and the second tension roller 32 on both sides to move in opposite directions, adjusting the distance between the first tension roller 31 and the second tension roller 32, which facilitates tension adjustment for different fabrics.

[0040] Referring to Figure 4, a guide rod 124 is slidably mounted on the connecting block 123. The guide rod 124 is perpendicular to the connecting block 123. A mounting plate 125 is provided at one end of the guide rod 124, and a spring 126 is sleeved on the guide rod 124. One end of the spring 126 is connected to the mounting plate 125, and the end of the spring 126 away from the mounting plate 125 is connected to one side of the connecting block 123. The two ends of the first tension roller 31 and the second tension roller 32 are rotatably connected to the mounting plates 125 on both sides, respectively. When the fabric is subjected to the tension of the first tension roller 31 and the second tension roller 32, the first tension roller 31 and the second tension roller 32 are pulled, causing the guide rod 124 to slide. At this time, the spring 126 is compressed, and the elastic spring 126 presses against the fabric, reducing the probability of damaging the fabric.

[0041] Referring to Figure 2, flattening rollers 13 are arranged on the fabric feed frame 1 and on both sides of the steam preheating hood 4. Two flattening rollers 13 are arranged as a group and are distributed parallel to each other. The fabric passes between the upper and lower flattening rollers 13 to flatten the fabric and further reduce wrinkles on the fabric.

[0042] Referring to Figure 2, several heat-spreading plates 42 are vertically arranged inside the steam preheating hood 4, and the heat-spreading plates 42 are evenly spaced along the length of the steam preheating hood 4. The heat-spreading plates 42 uniformly guide the steam delivered from the steam preheating hood 4, resulting in a better ironing effect on the fabric.

[0043] The implementation principle of the fabric feeding device of the long ring steaming machine in this application embodiment is as follows: the fabric is transported on the guide roller 11, and after being expanded by the expansion roller 2, it is tensioned by the first tension roller 31 and the second tension roller 32, and then enters the steam preheating hood 4. The steam from the steam preheating hoods 4 on both sides preheats and flattens the fabric, reduces wrinkles on the fabric, and improves the effect of the fabric steaming operation in the long ring steaming machine.

[0044] When tensioning different fabrics, the drive motor 61 drives the lead screw 62 to rotate, which in turn drives the rack 52 to move. The rack 52 drives the gear 51 to rotate, which in turn drives the rotating frame 12 to rotate, adjusting the position of the first tensioning roller 31 and the second tensioning roller 32. At the same time, the adjusting screw 122 is rotated to adjust the distance between the two tensioning rollers, which is suitable for tensioning different fabrics.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
