Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a spreading and rolling mill device and a stretching and setting system. Background Technology

[0002] Fabrics treated by dyeing and finishing processes generally retain a certain amount of humidity and temperature before being sent to the heat setting machine. In particular, when fabrics containing elastic fibers such as spandex are transported along the feed direction (i.e., the length direction), the two sides in the width direction are prone to wrinkles (e.g., the edges are wavy, slightly folded, etc.) and curls (e.g., the edges curl inward or outward, are tubular, or have multiple folds).

[0003] However, in the existing technology, the edge spreading mechanism is only provided before the fabric is fed into the heat setting machine. As a result, before the fabric enters the feed rail and heat setting machine, the sides of the fabric with curls or wrinkles are easily squeezed by the rollers on the feed rail, causing deformation and creases. It is difficult to unfold and repair them through the subsequent edge spreading mechanism, so the fabric cannot have good flatness before entering the heat setting machine.

[0004] It should be noted that the above description of the background technology is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background technology section of this utility model. Utility Model Content

[0005] The purpose of this invention is to disclose a spreading and rolling device and a stretching and setting system, and to eliminate the defects of wrinkles and curls on the sides of the fabric, so as to ensure that the fabric has good flatness before being sent into the heat setting machine.

[0006] To achieve the above objectives, in a first aspect, this utility model provides a fabric spreading and rolling device, comprising: a fabric feeding frame;

[0007] Two rollers are mounted on the fabric feeding frame and rotate in opposite directions;

[0008] Two edge-spreading mechanisms are symmetrically arranged on both sides of the fabric feed frame along the fabric width direction, and are arranged on the upstream side of the two rollers along the fabric feed path;

[0009] The edge-stretching mechanism includes: a base plate and a pressure plate arranged opposite to each other, and two sets of inclined tooth plates respectively disposed on the inner opposing surfaces of the base plate and the pressure plate;

[0010] A working gap for clamping the fabric is formed between the inclined toothed plate disposed on the inner side of the base plate and the inclined toothed plate disposed on the inner side of the pressure plate.

[0011] As a further improvement of this utility model, the first feeding direction of the fabric entering the two rollers through the edge spreading mechanism forms a first set angle with the connecting line direction formed by the connection of the axes of the two rollers, and the first set angle is 90°.

[0012] As a further improvement of this utility model, the first feeding direction forms a second predetermined angle with the horizontal plane, and the connecting line direction forms a third predetermined angle with the horizontal plane, wherein the second predetermined angle and the third predetermined angle are complementary angles to each other.

[0013] As a further improvement of this utility model, the edge-spreading rolling device further includes: a guide roller disposed on the fabric feeding frame, the guide roller being disposed downstream of the two rollers along the fabric feeding path, the fabric entering the guide roller through the two rollers forming a second feeding direction forming a fourth predetermined angle with the horizontal plane, the fourth predetermined angle being equal to the second predetermined angle.

[0014] As a further improvement of this utility model, the edge-spreading rolling device further includes: a tension roller disposed on the fabric feeding frame, the tension roller being disposed downstream of the guide roller along the fabric feeding path.

[0015] As a further improvement of this utility model, the edge-spreading rolling device further includes: a filament-splitting roller disposed on the fabric feeding frame, the filament-splitting roller being disposed on the upstream side of the edge-spreading mechanism along the fabric feeding path.

[0016] As a further improvement of this utility model, each set of inclined toothed plates includes: a toothed plate, a plurality of toothed blocks protruding from the toothed plate, each of the toothed blocks extending at a set angle to the fabric feeding direction and arranged parallel to each other;

[0017] The toothed blocks contained in the inclined toothed plate disposed on the inner side of the base plate and the toothed blocks contained in the inclined toothed plate disposed on the inner side of the pressure plate are staggered along the fabric feeding path to form a working gap for clamping the fabric.

[0018] As a further improvement of this utility model, the edge-spreading mechanism further includes: a fourth oblique tooth plate disposed on the base plate, the fourth oblique tooth plate being disposed on the downstream side of the oblique tooth plate along the fabric feeding path.

[0019] As a further improvement of this utility model, the fourth oblique toothed plate includes: a fourth toothed plate, and a plurality of fourth toothed blocks formed on the fourth toothed plate, each of the fourth toothed blocks extending obliquely at a set angle to the fabric feeding direction and arranged parallel to each other.

[0020] Secondly, this utility model also provides a stretching and setting system, comprising: a stretching roller device as described in any one of the first aspects, and a heat setting machine disposed downstream of the stretching roller device along the fabric feeding path.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: After the dyeing and finishing process, the fabric is conveyed to the edge-unfolding roller device. The two sides of the fabric are aligned with the edge-unfolding mechanisms on both sides of the fabric feed frame and enter the working gap between the first oblique tooth plate on the base plate and the second oblique tooth plate on the pressure plate. As the fabric is continuously conveyed, the first oblique tooth plate and the second oblique tooth plate can form an outward tensile force on the sides of the fabric along the fabric width direction to gradually unfold and flatten the wrinkles and curls on the sides of the fabric. The fabric with flat sides after edge-unfolding is conveyed along the feed path to the area between the two downstream rollers. The two rollers rotating in opposite directions roll into contact with the fabric surface to apply uniform pressure to the entire fabric, squeeze out the moisture in the fabric, and further flatten the slightly uneven areas on the fabric surface, compact the fiber arrangement, maintain the flat shape of the fabric after edge-unfolding, and prevent the sides of the fabric from wrinkling or curling again due to elastic rebound. This ensures that the fabric has good flatness before being sent to the heat setting machine, thereby avoiding deformation and creases caused by roller squeezing before the fabric enters the heat setting machine.

[0028] The present utility model will be described in detail below with reference to the embodiments shown in the accompanying drawings, but it should be noted that these embodiments do not limit the present utility model. Any equivalent change or substitution in function, method or structure made by those skilled in the art according to these embodiments shall fall within the protection scope of the present utility model.

[0029] The drawings of the present utility model are not drawn strictly to actual scale, and the specific dimensions of each structure can be determined according to actual needs. The drawings described in the present utility model are merely structural schematic diagrams. The lines shown in the accompanying drawings contained in the description of the present utility model can be understood as components with a certain actual thickness.

[0030] Please refer to Figures 1 to 6 disclosed is a specific embodiment of a selvage opening squeezing device and a tenter setting system.

[0031] Referring to Figures 1 to 3 shown, in the present embodiment, the selvage opening squeezing device 100 includes: a fabric feed frame (not shown); two squeeze rollers 20 arranged on the fabric feed frame and rotating towards each other; two selvage opening mechanisms 30 symmetrically arranged on both sides of the fabric feed frame along the width direction of the fabric 200 (as in Figure 1 X-axis in the figure) and arranged on the upstream side of the two squeeze rollers 20 along the fabric feeding path of the fabric 200; the selvage opening mechanism 30 includes: a bottom plate 31 and a pressing plate 32 arranged oppositely, and two groups of helical tooth plates 33 respectively arranged on the inner opposite surfaces of the bottom plate 31 and the pressing plate 32; a working gap for clamping the fabric 200 is formed between the helical tooth plate arranged on the inner side of the bottom plate 31 and the helical tooth plate arranged on the inner side of the pressing plate 32.

[0032] Fabrics after dyeing and finishing processes, especially those containing elastic fibers such as spandex, retain certain humidity and temperature, and the two sides are prone to wrinkled edges and curled edges during fabric feeding and transmission. In the prior art, a selvage opening mechanism is only provided before the fabric is fed into the heat setting machine, which results in that the unflattened side edges of the fabric are squeezed by the squeeze rollers to produce deformation and creases before the fabric enters the feeding track and the heat setting machine through the fabric feed frame.

[0033] During the operation of the selvage opening squeezing device 100 disclosed in the present utility model, the fabric 200 after dyeing and finishing process is along Figure 2The fabric 200 is conveyed to the edge-unfolding roller device 100 in the direction indicated by the middle arrow Y. The two sides of the fabric 200 align with the edge-unfolding mechanisms 30 on both sides of the fabric feed frame and enter the working gap between the first oblique toothed plate 331 on the base plate 31 and the second oblique toothed plate 332 on the pressure plate 32. The first oblique toothed plate 331 and the second oblique toothed plate 332 engage to form an interlaced clamping structure, which clamps the sides of the fabric 200. As the fabric 200 continues to be conveyed, the first oblique toothed plate 331 and the second oblique toothed plate 332 exert an outward tensile force along the width direction of the fabric 200 on the sides, gradually unfolding and flattening the wrinkles and curls on the sides of the fabric 200. After edge-unfolding treatment, the fabric 200 with flattened sides is conveyed along the fabric feed path to the area between the two downstream rollers 20. Two opposing rollers 20 roll in contact with the surface of the fabric 200 to apply uniform pressure to the entire fabric 200, squeeze out the moisture in the fabric 200, and further flatten the slightly uneven areas on the surface of the fabric 200, compact the fiber arrangement, so as to maintain the flat shape of the fabric 200 after the edges are unfolded, and prevent the sides of the fabric 200 from wrinkling or curling again due to elastic rebound. This ensures that the fabric 200 has good flatness before being sent into the heat setting machine, thereby avoiding deformation and creases caused by the rollers before the fabric 200 enters the heat setting machine.

[0034] In some examples, the parameter Figure 4 and Figure 5 As shown, the fabric 200 enters the first feeding direction formed by the two rollers 20 via the edge-spreading mechanism 30. The line b1 connecting the axes of the two rollers 20 forms a first set angle c1, and this first set angle c1 is 90°. The two rollers 20 are respectively configured as a first roller 21 and a second roller 22. The first roller 21 and the second roller 22 are respectively along... Figure 1 The directions indicated by the middle arrows G1 and G2 rotate in opposite directions on the feed frame. The axis of the first roll 21 is connected to the axis of the second roll 22 to form a connecting line b1, and the first feed direction forms a first set angle c1 with the connecting line b1. Exemplarily, the first roll 21 and the second roll 22 can be configured as liquid-pressing rolls with rubber roller surfaces, and the liquid-pressing rolls have a cooling function.

[0035] During the stage where the fabric 200 enters the two rollers 20 via the edge-spreading mechanism 30, the contact arc length between the fabric 200 and the first roller 21 and the second roller 22 is determined by the entry angle (i.e., the feed angle of the fabric 200 into the two rollers 20, which is the angle between the first feed direction and the horizontal plane). If the feed angle of the fabric 200 into the two rollers 20 deviates from 90°, it will result in uneven contact areas between the fabric 200 and the first roller 21 and the second roller 22. For example, if there are areas where the contact arc length between the fabric 200 and the first roller 21 is excessively long, the pressure on the corresponding part of the first roller 21 will be concentrated, while the overall contact arc length between the fabric 200 and the second roller 22 will be too short, resulting in dispersed force and lower pressure on the second roller 22. This uneven force distribution between the first roller 21 and the second roller 22 will affect their service life.

[0036] In the operation of the edge-unfolding rolling device 100 disclosed in this utility model, the fabric 200 enters the two rollers 20 at a 90° angle, ensuring that the force exerted by the fabric 200 on the first roller 21 and the second roller 22 is perpendicular to the axis connecting the axes, b1. This ensures that the contact arc length between the fabric 200 and the first roller 21 and the second roller 22 is uniform along the roller surface axially, avoiding situations where the local arc length is too long or too short. This results in equal radial pressure on the first roller 21 and the second roller 22, preventing uneven wear and accelerated aging of the rubber layer caused by localized pressure concentration on a single roller (first roller 21 or second roller 22). Simultaneously, it maintains consistent bearing loads on the first roller 21 and the second roller 22, extending the service life of the first roller 21 and the second roller 22 and their associated components, and reducing equipment maintenance costs. Furthermore, the first roller 21 and the second roller 22 can apply uniform pressure to the entire width of the fabric 200, simultaneously compacting the fibers on both sides and in the middle of the fabric 200, further fixing the flat shape of the fabric 200 after it has been stretched by the edge spreading mechanism 30.

[0037] In some examples, the parameter Figure 4 and Figure 5 As shown, the first feeding direction forms a second set angle c2 with the horizontal plane, and the connecting line direction forms a third set angle c3 with the horizontal plane. The second set angle c2 and the third set angle c3 are complementary angles.

[0038] By setting the first set angle c1 to 90°, and the second set angle c2 and the third set angle c3 being complementary angles (the sum of the second set angle c2 and the third set angle c3 is 90°), it can be ensured that the fabric 200 always enters between the first roller 21 and the second roller 22 in an attitude perpendicular to the axis line b1. This prevents the fabric 200 from deviating from the 90° angle when entering the two rollers 20, thereby avoiding uneven distribution of the contact arc length between the fabric 200 and the first roller 21 and the second roller 22, and preventing the problem of local pressure concentration on one roller and force dispersion on the other roller. Furthermore, by using the second set angle c2 and the third set angle c3 as complementary angles, the installation tilt angle of the two rollers 20 (i.e., the third set angle c3) and the fabric 200 feed tilt angle (i.e., the second set angle c2) can be set to a quantitative relationship of 90° - third set angle c3 = second set angle c2. This ensures that the fabric output tilt angle of the edge spreading mechanism 30 matches the second set angle c2, and the installation tilt angle of the axis connecting line b1 of the two rollers 20 matches the third set angle c3. This avoids angular deviations when the edge spreading mechanism 30 and the two rollers 20 are installed, ensuring that the fabric 200 feeds into the two rollers 20 at a feed angle of 90°.

[0039] In dyeing and finishing production lines, the installation height of the edge-stretching mechanism 30 and the two rollers 20 on the feed frame may often be adjusted due to site or process requirements. Through the aforementioned angle constraint (i.e., the quantitative relationship of 90° - third set angle c3 = second set angle c2), the two rollers 20 can be flexibly adjusted at the third set angle c3. The edge-stretching mechanism 30 only needs to synchronously adjust the second set angle c2 to maintain the fabric 200 vertically entering between the two rollers 20, thus adapting to production lines with different spatial layouts. For example, as... Figure 4 As shown, when the line b1 connecting the axes of the two rollers 20 forms a 45° angle with the horizontal plane, the fabric 200, after passing through the spreading mechanism 30, also forms a 45° angle with the horizontal plane. Figure 5 As shown, when the line b1 connecting the axes of the two rollers 20 is inclined at a 90° angle to the horizontal plane, the fabric 200 exits at 0° to the horizontal plane after passing through the edge spreading mechanism 30.

[0040] In some examples, the parameter Figure 4 and Figure 5 As shown, the edge-spreading rolling device 100 further includes: a guide roller 40 disposed on the fabric feed frame. The guide roller 40 is disposed on the downstream side of the two rollers 20 along the fabric feeding path of the fabric 200. The fabric 200 enters the guide roller 40 through the two rollers 20, forming a second feeding direction with the horizontal plane and forming a fourth set angle c4. The fourth set angle c4 is equal to the second set angle c2.

[0041] During the stage where the fabric 200 is output from the two rollers 20 and enters the guide roller 40, the contact arc length between the fabric 200 and the first roller 21 and the second roller 22 is determined by the exit roller angle (i.e., the fourth set angle c4 formed by the second feeding direction of the fabric 200 and the horizontal plane). If the feeding angle of the fabric 200 entering the guide roller 40 is different from the entering roller angle (i.e., the second set angle c2 formed by the first feeding direction of the fabric 200 and the horizontal plane), it will cause the posture of the fabric 200 entering and exiting the rollers to be asymmetrical, thereby resulting in uneven contact areas between the fabric 200 and the two rollers 20. By setting the entry angle of the fabric 200 from the edge spreading mechanism 30 to the two rollers 20 to be equal to the exit angle of the fabric 200 from the two rollers 20 to the guide roller 40, the fabric 200 can enter and exit the rollers in a symmetrical posture. This ensures that the contact arc length between the fabric 200 and the first roller 21 and the second roller 22 is uniform, so that the rolling pressure distribution on the entire width of the fabric 200 is balanced. This avoids the pressure concentration problem caused by excessive local contact arc length of the first roller 21 or the second roller 22, thereby preventing uneven wear of the rollers and accelerated aging of the rubber layer.

[0042] In some examples, the parameter Figure 1 As shown, the edge-spreading and pressing device 100 also includes a tension roller 60 disposed on the fabric feed frame, which is located downstream of the guide roller 40 along the fabric feeding path of the fabric 200. By sequentially arranging the guide roller 40 and the tension roller 60 downstream of the two rollers 20, the tension roller 60 can adjust the tension of the fabric 200 in real time, preventing the fabric 200 from becoming loose or sagging between the edge-spreading mechanism 30, the two rollers 20, and the guide roller 40. This ensures that the fabric 200 remains flat and taut after edge spreading and pressing, preventing the stretched edges from springing back and curling due to fabric 200 loosening, and ensuring that the fabric 200 enters the subsequent processes at a uniform speed and in a smooth manner.

[0043] In some examples, the parameter Figure 1 As shown, the edge-stretching device 100 also includes a yarn-separating roller 50 disposed on the fabric feed frame. The yarn-separating roller 50 is disposed on the upstream side of the edge-stretching mechanism 30 along the fabric feeding path of the fabric 200. The yarn-separating roller 50 can guide the fabric 200 into the edge-stretching mechanism 30 in a flat and taut state. The fine grooves (not shown) or toothed structures (not shown) provided on the surface of the yarn-separating roller 50 can pre-treat the fabric 200, sort out the yarn entanglement and misalignment problems remaining after the dyeing and finishing process of the fabric 200, and can also perform preliminary pre-stretching of the fabric 200 to improve the accuracy of subsequent edge-stretching.

[0044] In some examples, the parameter Figure 3 and Figure 6As shown, each set of inclined toothed plates 33 includes: a toothed plate, and multiple toothed blocks protruding from the toothed plate. Each toothed block extends obliquely at a set angle to the fabric feeding direction of the fabric 200 and is arranged parallel to each other. The toothed blocks contained in the inclined toothed plate 33 disposed on the inner side of the base plate 31 and the toothed blocks contained in the inclined toothed plate 33 disposed on the inner side of the pressure plate 32 are staggered along the fabric feeding path of the fabric 200 to form a working gap for clamping the fabric 200. When the fabric 200 passes through the inclined toothed plate 33 along the feeding path, the obliquely extending toothed blocks will form a lateral stretching force on the side of the fabric 200, which can gradually unfold the rolled edges and wrinkles on the side of the fabric 200, and realize the flattening of the side of the fabric 200. The interlocking clamping structure is formed by the meshing of the toothed blocks of the inclined toothed plate on the inner side of the base plate 31 and the toothed blocks of the inclined toothed plate on the inner side of the pressure plate 32. This structure can stably clamp the fabric 200, prevent the fabric 200 from shifting during transmission, and ensure that the sides of the fabric 200 are stretched and stretched synchronously and evenly, preventing local overstretching or understretching.

[0045] In some examples, the parameter Figure 6 As shown, the first oblique toothed plate 331 and the second oblique toothed plate 332 have the same structure. The first oblique toothed plate 331 is used as an example for illustration. The first oblique toothed plate 331 is configured with a first toothed plate 3311, a second toothed plate 3313, and a third toothed plate 3315 arranged sequentially along the fabric feeding path of the fabric 200, and first toothed blocks 3312, second toothed blocks 3314, and third toothed blocks 3316 formed on the first toothed plate 3311, the second toothed plate 3313, and the third toothed plate 3315, respectively. The first toothed blocks 3312, the second toothed blocks 3314, and the third toothed blocks 3316 all extend obliquely at a set angle to the fabric feeding direction of the fabric 200 and are arranged parallel to each other. The spacing between the first toothed blocks 3312 is greater than the spacing between the second toothed blocks 3314, and the spacing between the second toothed blocks 3314 is greater than the spacing between the third toothed blocks 3316. The first toothed block 3312 has the largest spacing, which can initially stretch and smooth out obvious curling and wrinkling issues on the sides of the fabric 200. The second toothed block 3314 has a moderate spacing, continuing the processing effect of the first toothed block 3312, and further smoothing out any remaining curling and wrinkling on the sides of the fabric 200. The third toothed block 3316 has the smallest spacing and a denser contact point with the fabric 200, which can finely smooth out the fine wrinkles on the sides of the fabric 200, gradually improving the smoothness of the sides of the fabric 200, so as to achieve a gradual stretching and shaping of the sides of the fabric 200.

[0046] In some examples, the parameter Figure 6As shown, the edge-stretching mechanism 30 also includes a fourth oblique toothed plate 35 disposed on the base plate 31. The fourth oblique toothed plate 35 is located downstream of the oblique toothed plate 33 along the fabric feeding path of the fabric 200. The fourth oblique toothed plate 35 can receive the fabric 200 after it has been stretched and shaped by the oblique toothed plate 33, guide the fabric 200 to move smoothly along the preset feeding path, and correct any slight deviations that may occur in the fabric 200 during transmission due to equipment vibration or small fluctuations in tension.

[0047] In some examples, the parameter Figure 6 As shown, the fourth oblique toothed plate 35 includes a fourth toothed plate 351 and a plurality of fourth toothed blocks 352 formed on the fourth toothed plate 351. Each fourth toothed block 352 extends obliquely at a set angle to the fabric feeding direction of the fabric 200 and is arranged parallel to each other. The spacing between the fourth toothed blocks 352 is smaller than the spacing between the toothed blocks in the oblique toothed plate 33. The fourth toothed blocks 352 receive the fabric 200 after it has been stretched by the edge-spreading mechanism 30. By using the contact between the fourth toothed blocks 352 and the fabric 200, the slight deviation of the fabric 200 caused by equipment vibration and tension fluctuation is corrected, ensuring that the fabric 200 smoothly enters the subsequent roller process along the preset feeding path. Compared to the oblique tooth plate 33, the arrangement spacing of the fourth tooth block 352 is smaller than that of the third tooth block 3316. The contact points between the fourth tooth block 352 and the fabric 200 are more dense, which can comb the side of the fabric 200 more finely, further straighten the fine fiber entanglement left after the oblique tooth plate 33 treatment, and continuously maintain the flatness of the side of the fabric 200.

[0048] Based on the technical solution of the edge-spreading roller device 100 disclosed in the foregoing embodiments, this embodiment also discloses a tenter frame system (not shown). The tenter frame system includes: the edge-spreading roller device 100 as disclosed in the above embodiments, and a heat setting machine (not shown) disposed downstream of the edge-spreading roller device 100 along the fabric feeding path of the fabric 200. The specific technical solution of the edge-spreading roller device 100 included in the tenter frame system in this embodiment is the same as that in the foregoing embodiments, and will not be repeated here. The edge-spreading roller device 100 can eliminate the curling and wrinkling problems remaining on the fabric 200 after the dyeing and finishing process, initially fix the flat shape of the fabric 200, ensure that the fabric has uniform tension across the entire width before entering the heat setting machine, no local deformation, and good flatness, and avoid deformation and creases caused by the rollers before the fabric 200 enters the heat setting machine. The heat setting machine takes over the pretreatment effect of the edge spreading and rolling device 100 on the fabric 200. Through the synergistic effect of high temperature heating and tension stretching, the molecular structure of the fibers of the fabric 200 is reorganized and fixed, eliminating the elastic rebound tendency of the fabric 200, and finally achieving a high-quality setting effect with stable width and dimension, smooth and clean surface, and no curling or wrinkles on the sides.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
