Description

Technical Field

[0001] This utility model belongs to the field of fabric unwinding and feeding technology, and particularly relates to a fabric unwinding, feeding and stretching device. Background Technology

[0002] Fabrics such as knitted fabrics are produced through machine spinning and weaving. After the spinning and weaving process is completed, the fabric is often wound into a roll using a roll-up device. Subsequently, the fabric roll is unwound by processing equipment and then further processed, including various finishing processes such as heat pressing and hemming.

[0003] During the production process, including fabric conveying and winding, the fabric is prone to developing incompletely unfolded wrinkles and burrs. To address these wrinkles and burrs, existing technologies utilize fabric guide rollers on the unwinding and conveying equipment. These rollers guide the fabric and, when the fabric passes against them, the friction between the rollers and the fabric smooths out the wrinkles and burrs.

[0004] However, in actual processing, while multiple guide rollers can indeed fully smooth out minor wrinkles and burrs on the fabric, it is difficult to effectively remove and smooth out burrs and wrinkles on the fabric when the wrinkles are deep, there are many burrs, or other defects.

[0005] The specific reason is that the surface of structures such as guide rollers becomes very smooth after repeated friction with the fabric, making it difficult to smooth out fabrics with severe burrs and wrinkles.

[0006] Therefore, improving the structure of existing fabric processing and conveying equipment and solving the technical problems of severe burrs and wrinkles in fabrics is very important for improving fabric production efficiency. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a fabric unwinding, feeding, and stretching device.

[0009] A fabric unwinding and feeding stretching device includes a frame, an unwinding mechanism for unwinding fabric installed at the end of the frame, and a fabric stretching and wrinkle removal mechanism disposed at the outlet end of the unwinding mechanism.

[0010] The fabric stretching and wrinkle removal mechanism includes a bracket mounted on a frame. An angle adjustment rod is respectively connected to the feed end and the discharge end of the bracket. A stretching bracket for flattening the fabric is respectively mounted on the angle adjustment rod.

[0011] The stretching support consists of a stretching plate that rests against the fabric.

[0012] Preferably, the unwinding mechanism includes a roll shaft with a roll of fabric wound on it, with rotating brackets detachably mounted at both ends of the roll shaft, and rotating shafts rotatably connected to the frame fixedly connected to the rotating brackets, and bearing brackets rotatably connected to the rotating shafts mounted on both sides of the top of the frame.

[0013] It also includes a motor that drives the roll shaft to rotate.

[0014] Preferably, the rotating bracket has mounting seats for detachably mounting the roll shaft on its opposite sidewalls. The mounting seats have limiting grooves for positioning the roll shaft and locking screws for locking the roll shaft are threaded onto the mounting seats.

[0015] Preferably, the bracket has a long adjustment through hole;

[0016] The long adjusting through hole is internally threaded with a long adjusting rod, and connecting bracket rods are fixedly connected to both sides of the long adjusting rod. A bracket rod seat is welded onto the connecting bracket rod, and the angle adjusting rod is threaded between the bracket rod seats.

[0017] Preferably, the outer end of the long adjusting rod is fixedly connected to a rotating handwheel located outside the long adjusting through hole.

[0018] Preferably, the top of the stretching plate is integrally formed with a mounting part, and the angle adjustment rod is threadedly connected to a pair of spaced mounting screws, which are threadedly connected to the top position of the mounting part.

[0019] Preferably, a pair of spaced-apart fabric cleaning mechanisms are installed at the discharge end of the fabric stretching and pleating mechanism.

[0020] The fabric cleaning mechanism is used to clean the top and bottom of the fabric.

[0021] Preferably, the fabric cleaning mechanism includes a cleaning shaft rotatably connected to both sides of the frame, and a bearing bracket installed at the top of the frame is rotatably connected to both ends of the cleaning shaft. A ring bracket is fixedly installed on both sides of the cleaning shaft, and a plurality of brushes are fixedly installed between the ring brackets.

[0022] The brush includes a rod and bristles mounted on the rod;

[0023] It also includes a drive motor for rotating the sweeping shaft.

[0024] Preferably, a guide roller structure is provided between the unwinding mechanism and the fabric stretching and pleating mechanism;

[0025] A guide roller structure is provided between the fabric cleaning mechanisms.

[0026] Preferably, the frame is equipped with a plurality of guide roller structures for guiding the fabric;

[0027] The guide roller structure includes a guide roller, and bearing brackets are rotatably connected to both ends of the guide roller, with the bearing brackets fixedly installed on the frame.

[0028] This utility model has the following beneficial effects:

[0029] 1. Angle adjustment rods are respectively installed and connected to the feed end (left side) and discharge end (right side) of the bracket, and stretching brackets for flattening the fabric are respectively installed on the angle adjustment rods; the stretching brackets include stretching plates that abut against the fabric.

[0030] During the process, the fabric rubs through the bottom of the stretching plate on the left, then through the top of the support, and finally through the top of the stretching plate on the right, thus rubbing the fabric. As a result, the wrinkles and burrs on the fabric can be smoothed out and removed by the rubbing action of the stretching plate.

[0031] 2. The bracket has a rectangular adjustment through-hole. A long adjustment rod is threaded into this through-hole, with both ends passing through the bracket. A rotary handwheel is fixedly installed at the rear end for easy adjustment of the long adjustment rod. During operation, the angle of the two side spreading plates can be adjusted to moderately change the contact angle with the fabric (small-range simultaneous adjustment of both spreading plates), achieving optimal angle and posture on the fabric to enhance the removal of wrinkles and burrs.

[0032] 3. The angle adjustment rod allows for individual adjustment of the angle and posture of each stretching board. This is because when the fabric passes through the bottom and top of the two stretching boards, individual adjustment increases the effect on the fabric, such as the resistance effect (large-range individual adjustment).

[0033] 4. By independently and synchronously adjusting the stretching boards in a large and small range, the stretching boards on both sides are made to contact the fabric in the best contact posture, so as to fully treat the wrinkles and burrs on the fabric.

[0034] 5. The fabric cleaning mechanism thoroughly cleans dirt and removes burrs from the fabric. Attached Figure Description

[0047] Example 1

[0048] like Figure 1-7 As shown, a fabric unwinding and feeding device includes a frame 1, with an unwinding mechanism 2 for unwinding fabric installed at the left end of the frame 1. Similar to existing methods, a fabric winding mechanism (not shown in the figure) is installed at the right end of the frame 1, which has the same structure as the unwinding mechanism 2 and is used to wind up the processed fabric.

[0049] Similar to the existing fabric unwinding mechanism 2, the unwinding mechanism 2 includes a roll shaft with a fabric roll 21 wound on it. Rotary supports 22 are detachably mounted at both ends of the roll shaft. Rotary shafts rotatably connected to the frame 1 are fixedly connected to the rotating supports 22. Correspondingly, bearing supports 24 rotatably connected to the rotating shafts are mounted on both sides of the top of the frame 1. It also includes a motor 23 that drives the roll shaft to rotate. Specifically, similar to existing methods, the output shaft of the motor 23 is mounted on the rotating shaft via a coupling, enabling the motor to drive the roll shaft to rotate, thus unwinding the fabric wound on the roll shaft. Similarly, the winding mechanism winds up the fabric.

[0050] To facilitate the loading and unloading of fabric rolls, similar to existing detachable fabric roll installation methods, mounting seats 221 for detachable fabric roll shafts are installed on the opposing side walls of the rotating bracket 22. Each mounting seat 221 has a limiting groove for positioning the fabric roll shaft, and a locking screw 2211 is threadedly connected to the mounting seat 221 to lock the fabric roll shaft. The locking screw 2211 passes through a through hole on the fabric roll shaft and is threadedly connected to a nut, enabling detachment.

[0051] Example 2

[0052] like Figure 1-7 As shown, based on the structure of Example 1, this embodiment makes the following improvements to fully stretch the fabric during fabric transport, smooth out wrinkles, especially severe wrinkles, and remove burrs:

[0053] It also includes a fabric stretching and wrinkle removal mechanism 4 located at the discharge end of the unwinding mechanism 2; specifically, the fabric stretching and wrinkle removal mechanism 4 includes a bracket 41 installed on the frame 1 (the installation method is: mounting rods are fixedly installed on the left and right sides of the front and rear ends of the bracket 41, and the mounting rods are respectively installed on the frame 1, specifically, the mounting rods are fixedly installed with a bracket plate 411, and the bracket plate 411 is fastened to the frame 1 by bolts).

[0054] Meanwhile, angle adjustment rods 43 are respectively installed and connected to the feed end (left side) and discharge end (right side) of the bracket 41. Angle adjustment rods 43 are respectively equipped with stretching brackets 41 for flattening the fabric. The stretching brackets 41 include stretching plates 44 that abut against the fabric.

[0055] During the process, the fabric rubs through the bottom of the stretching plate 44 on the left, then through the top of the support 41, and finally through the top of the stretching plate 44 on the right, thus rubbing the fabric. As a result, the wrinkles and burrs on the fabric can be smoothed out and removed by the rubbing action of the stretching plate 44.

[0056] The bottom of the stretching board 44 is smoothed, so it will not scratch the fabric during actual use.

[0057] Specifically, the bracket 41 has a rectangular long adjustment through hole. A long adjustment rod 42 is threaded into the long adjustment through hole, with both ends of the rod passing through both ends of the bracket 41. A rotating handwheel 421 is fixedly installed at the rear end for easy adjustment of the long adjustment rod 42. During operation, the angle of the two side stretching plates 44 can be moderately adjusted by turning the long adjustment rod 42. Adjusting the angle of the stretching plates 44 moderately changes the contact angle with the fabric (small-range synchronous adjustment of the two side stretching plates 44), achieving optimal angle and posture on the fabric to enhance the removal of wrinkles and burrs.

[0058] The front and rear ends of the aforementioned long adjusting rod 42 are respectively fixedly connected to a pair of left and right connecting bracket rods 4311. A bracket rod seat 431 is welded onto the connecting bracket rod 4311, and the angle adjusting rod 43 is threadedly connected between the bracket rod seats 431.

[0059] The angle adjustment rod 43 enables individual angle and posture adjustment of each stretching plate 44. This is because when the fabric passes through the bottom and top positions of the two stretching plates 44, the individual adjustment increases the effect on the fabric, such as the resistance effect (large-range individual adjustment).

[0060] During the adjustment process, since the lengths of the angle adjustment rod 43 and the long adjustment rod 42 are both greater than the width of the fabric, and the horizontal ends of the angle adjustment rod 43 and the long adjustment rod 42 can still fully contact the fabric after moving a short distance during the angle adjustment process.

[0061] After passing through the left stretching plate 44, the fabric passes through the gap between the connecting support rods 4311, then passes under the top of the support 41, passes between the connecting support rods 4311 on the other side, and then passes through the bottom of the right stretching plate 44.

[0062] The aforementioned stretching plate 44 is installed on the angle adjustment rod 43 in the following manner:

[0063] Preferably, the top of the stretching plate 44 is integrally formed with a mounting portion 441, and the angle adjustment rod 43 is threadedly connected to a pair of spaced-apart mounting screws A, with the mounting screws A threadedly connected to the top position of the mounting portion 441. This method enables the stretching plate 44 to be detachably installed.

[0064] To enhance the flattening effect of the stretching board 44, the stretching board 44 adopts a design that is wider at the top and narrower at the bottom, that is, the longitudinal cross-sectional shape is approximately triangular. This is intended to increase the pressure of contact between the stretching board 44 and the fabric by reducing the bottom width of the stretching board 44.

[0065] Example 3

[0066] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 1, a pair of spaced fabric cleaning mechanisms 5 are installed at the discharge end (right end) of the fabric stretching and pleating mechanism 4.

[0067] The fabric cleaning mechanism 5 removes burrs from the fabric after it has undergone the above-mentioned de-pleating and deburring process.

[0068] Specifically, the fabric cleaning mechanism 5 is used to clean the top and bottom of the fabric. The fabric cleaning mechanism 5 includes a cleaning shaft 52 rotatably connected to both sides of the frame 1. Each end of the cleaning shaft 52 is rotatably connected to a bearing bracket 51 installed at the top of the frame 1. Annular brackets 54 are fixedly installed on both sides of the cleaning shaft 52 (in existing methods, the annular brackets 54 are connected to the cleaning shaft 52 by mounting screws; that is, the mounting screws thread downwards from the top of the annular bracket 54, pass through the cleaning shaft 52, and then pass through the bottom of the annular bracket 54). Several brushes are fixedly installed between the annular brackets 54. The brushes are existing rod-type brushes; specifically, each brush includes a rod 55 and bristles 551 installed on the rod 55 (the two ends of the rod are fastened to the annular brackets 54 by bolts, allowing for easy disassembly).

[0069] Similar to existing drive methods, it also includes a drive motor 53 for driving the sweeping shaft 52 to rotate, and the output shaft of the drive motor 53 is mounted on the sweeping shaft 52 by means of a coupling.

[0070] During operation, when the fabric passes through the fabric cleaning mechanism 5 on both sides, that is, when the top and bottom surfaces of the fabric pass through the brushes, the fabric is cleaned by the high-speed rotating cleaning shaft 52 and the brush structure under the drive of the drive motor 53.

[0071] In actual operation, the bristles 551 are the flexible soft bristles disclosed in existing technology. The circumferentially distributed rod-bristle 551 structure aims to increase cleaning effectiveness because, with increased use, the bristles 551 not only accumulate more dirt but are also prone to breakage and deformation. Therefore, this structure allows for easy disassembly and replacement of the brush during operation. In contrast, traditional one-piece brush rollers require complete replacement once the bristles 551 deform or become dirty.

[0072] The bristles 551 on the high-speed rotating brush thoroughly shake off dirt, including burrs, from the fabric.

[0073] Example 4

[0074] like Figure 1-7 As shown, this embodiment is based on the structure of embodiment 3, and follows the same existing fabric conveying and guiding method. A guide roller structure 3 is provided between the unwinding mechanism 2 and the fabric unfolding and de-pleating mechanism 4. Specifically, three guide roller structures 3 with different heights are provided, with the middle one being higher and the two ends being lower, to guide and convey the fabric in an interlaced manner.

[0075] Similarly, a guide roller structure 3 is provided between the fabric cleaning mechanisms 5.

[0076] The guide roller structure 3 includes a guide roller, and the two ends of the guide roller are respectively rotatably connected to bearing brackets 41, which are fixedly installed on the frame 1.

[0077] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
