Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, in particular to a high-elastic knitted cloth and a winding device thereof. Background Art

[0002] Among the elastic fabrics, there is a kind of four-way stretch fabric, which is a kind of fabric that has elasticity in both up and down and left and right directions. It can adapt to the movement of the human body, stretch and shrink at will, and is light and comfortable. It can also maintain the beautiful appearance of the clothing, and the knees, elbows and other parts of the clothing will not be deformed and bulged due to long-term wearing.

[0003] While the fabric is being weaved, the woven fabric needs to be rolled up. However, when the existing rolling equipment is faced with highly elastic fabrics, the pulling force generated by the rolling up changes with the diameter of the roll, and the direction of the force will also change, causing the force of the fabric to resist the pulling effect to gradually increase, which can easily cause the fabric to deform. The rolled fabric is in a taut elastic state for a long time and is very likely to suffer from elastic fatigue damage.

[0004] The Chinese patent with the authorization announcement number CN217397985U discloses a winding device for high-elastic four-way stretch fabric, including a feeding platform, a cooling fan installed in the middle of the upper end of the feeding platform, five groups of rollers arranged horizontally above the feeding platform, and a winding platform arranged on the right side of the feeding platform. The winding device for high-elastic four-way stretch fabric uses a cooling fan to cool the elastic fabric during the winding process to reduce its elongation and deformation performance. As the fabric is rolled and thickened, the roller ensures that the winding plane of the fabric is kept horizontal with the top of the rolled fabric by vertical lifting, so as to avoid deformation caused by changes in the direction of the traction force on the fabric.

[0005] However, the above has the following shortcomings:

[0006] 1. Due to the characteristics of highly elastic fabrics, especially four-way stretch fabrics, when the fabric is stretched in the warp direction, wrinkles will appear in the weft direction of the fabric, and the edge of the fabric will shrink in an hourglass shape. At this time, rolling up the fabric will cause wrinkles that are difficult to smooth out. The above patent cannot deal with this problem, resulting in reduced rolling quality and affecting processing production efficiency.

[0007] 2. When rolling up the fabric, the fabric needs to be straightened, but the above patent only uses the rotational friction of the roller to reduce the traction on the fabric, thereby reducing the elastic stretching of the fabric, and cannot completely eliminate the traction on the fabric, resulting in the rolled-up high-elastic fabric still being in a stretched state, which is prone to elastic fatigue. Utility Model Content

[0008] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present utility model is that two sets of inclined rollers with an included angle in the conveying direction unfold the fabric to both sides while conveying the elastic fabric, avoiding the hourglass-shaped shrinkage of the fabric from affecting the winding quality, and the fabric is clamped and actively conveyed by the inclined rollers and the straight rollers to eliminate the elastic tension on the fabric between the winding component and the straight rollers and the inclined rollers, thereby avoiding the elastic fatigue caused by the fabric always being in a stretched state after winding. At the same time, while the winding component winds the fabric, by dynamically adjusting the height of the second lead screw frame, it is ensured that while the thickness of the wound fabric gradually increases, the conveying direction of the fabric remains horizontal with the winding direction, improving the winding stability and winding quality.

[0009] In order to achieve the above object, the present utility model provides the following technical solution: A high-elastic knitted fabric and its winding device, including a second lead screw frame, a second slide bar is fixedly connected between the two side plates of the second lead screw frame, two second sliders are slidably connected to the second slide bar, a second lead screw rotatably connected to the second lead screw frame is meshed and driven in each of the second sliders, one end of the second lead screw is drivingly connected to a second motor, a roller seat is rotatably connected in each of the second sliders, a set of inclined rollers is rotatably connected in each of the roller seats, a universal joint is fixedly connected to one end of each inclined roller away from the roller seat, and a straight roller is fixedly connected between the movable ends of two opposite universal joints. A winding component is arranged on one side of the second lead screw frame.

[0010] Two sets of inclined rollers with an included angle in the conveying direction unfold the fabric to both sides while conveying the elastic fabric, avoiding the hourglass-shaped shrinkage of the fabric from affecting the winding quality.

[0011] Further, two sets of first sliders are respectively fixedly connected to both sides of the second lead screw frame. One of the first sliders in each set of first sliders is slidably connected to a first slide bar, a base is fixedly connected to the bottom end of each first slide bar, a first lead screw rotatably connected to the base is meshed and driven in the other first slider in each set of first sliders, two first lead screw frames are fixedly connected to the upper side of the base at the corresponding positions of the two sets of first sliders, each first lead screw frame is fixedly connected to the corresponding first slide bar, and one end of each first lead screw extending out of the first lead screw frame is drivingly connected to a first motor.

[0012] While the winding component winds the fabric, by dynamically adjusting the height of the second lead screw frame, it is ensured that while the thickness of the wound fabric gradually increases, the conveying direction of the fabric remains horizontal with the winding direction, improving the winding stability and winding quality.

[0013] Further, two mutually meshing third gears are respectively fixedly connected to one ends of two inclined rollers on the same roller seat close to the roller seat, and a third motor is drivingly connected to one end of at least one inclined roller extending out of the first gear.

[0014] The fabric is supported and actively conveyed by the oblique rollers and the straight rollers, thereby eliminating the elastic tension on the fabric between the winding component and the straight rollers and the oblique rollers, thereby avoiding the fabric being in a stretched state after winding and causing elastic fatigue.

[0015] Furthermore, a plurality of friction strips are evenly distributed and fixedly connected on the outer surface of each of the straight rollers and the oblique rollers.

[0016] By arranging the friction strips, the friction between the oblique rollers and the straight rollers and the cloth is increased, thereby enhancing the supporting effect and flattening effect of the straight rollers and the oblique rollers on the cloth.

[0017] Furthermore, the winding component includes a winding seat, two of the winding seats are symmetrically distributed and fixedly connected to the upper side of the base, an inclined axis groove is opened at the upper end of each of the winding seats, a winding shaft is rotatably connected in the two axis grooves, a winding sleeve is slidably connected to the winding shaft, and two side plates are slidably connected to the winding shaft at both ends of the winding sleeve.

[0018] By providing the shaft groove, the reeling sleeve wrapped with the cloth can be conveniently removed after the reeling is completed, thereby improving efficiency.

[0019] Furthermore, one end of the reel extending out of one of the reel seats is fixedly connected to the first gear, and one side of the reel seat is fixedly connected to a fourth motor below the first gear, and the power output end of the fourth motor is transmission-connected to a second gear meshing with the first gear.

[0020] A high-elastic knitted fabric comprises a high-elastic knitted fabric, wherein the high-elastic knitted fabric is knitted by mixing pure cotton yarn with elastic yarn, and the high-elastic knitted fabric is knitted by 2×2 rib double-sided weft knitting.

[0021] In summary, compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) Two sets of inclined rollers with an angle in the conveying direction are used to spread the elastic fabric to both sides while conveying the fabric, so as to avoid the hourglass-shaped contraction of the fabric affecting the winding quality.

[0023] (2) By dynamically adjusting the height of the second screw frame, the thickness of the wound fabric is gradually increased while the direction of conveying the fabric is kept horizontal with the direction of winding, thereby improving the winding stability and winding quality.

[0024] (3) The fabric is supported and actively transported by the oblique roller and the straight roller, thereby eliminating the elastic tension on the fabric between the winding component and the straight roller and the oblique roller, thereby preventing the fabric from being in a stretched state after winding, which causes elastic fatigue.

Detailed implementation manners

[0034] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0035] Embodiment 1:

[0036] As Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a highly elastic knitted fabric and its winding device include a second lead screw frame 30. Between the two side plates of the second lead screw frame 30, a second slide bar 32 is fixedly connected. Two second sliders 33 are slidably connected to the second slide bar 32. A second lead screw 31 rotatably connected to the second lead screw frame 30 is meshed and driven in each second slider 33. One end of the second lead screw 31 is drivingly connected to a second motor 37. A roller seat 34 is rotatably connected in each second slider 33. A set of inclined rollers 13 is rotatably connected in each roller seat 34. A universal joint 28 is fixedly connected to one end of each inclined roller 13 away from the roller seat 34. A straight roller 12 is fixedly connected between the movable ends of two opposite universal joints 28. A winding component is arranged on one side of the second lead screw frame 30.

[0037] Through two sets of inclined rollers 13 with an included angle in the conveying direction, while conveying the elastic fabric, the fabric is unfolded to both sides, avoiding the hourglass-shaped contraction of the fabric from affecting the winding quality.

[0038] As Figure 1 、 Figure 4 and Figure 6 As shown, two sets of first sliders 19 are respectively fixedly connected to both sides of the second lead screw frame 30. One first slider 19 in each group of first sliders 19 is slidably connected to a first slide bar 17. The bottom end of each first slide bar 17 is fixedly connected to a base 11. The other first slider 19 in each group of first sliders 19 is meshed and driven with a first lead screw 16 rotatably connected to the base 11. Two first lead screw frames 15 are fixedly connected to the upper side of the base 11 at the corresponding positions of the two sets of first sliders 19. Each first lead screw frame 15 is fixedly connected to the corresponding first slide bar 17. One end of each first lead screw 16 extending out of the first lead screw frame 15 is drivingly connected to a first motor 18.

[0039] While the winding component winds the fabric, by dynamically adjusting the height of the second lead screw frame 30, it is ensured that while the thickness of the wound fabric gradually increases, the conveying direction of the fabric is kept horizontal with the winding direction, improving the winding stability and quality.

[0040] As Figure 7 As shown, two mutually meshing third gears 35 are respectively fixedly connected to the ends of two inclined rollers 13 on the same roller seat 34 close to the roller seat 34. One end of at least one inclined roller 13 extending out of the first gear 24 is drivingly connected to a third motor 36.

[0041] The inclined rollers 13 and the straight roller 12 are used to hold and actively convey the fabric, eliminating the elastic tension on the fabric between the winding component and the straight roller 12 and the inclined rollers 13, thus avoiding the elastic fatigue caused by the fabric always being in a stretched state after winding.

[0042] As Figure 2 、 Figure 5 and Figure 7As shown, a plurality of friction strips 29 are fixedly connected to the outer surfaces of each straight roller 12 and the inclined roller 13 in a uniformly distributed manner.

[0043] By providing the friction strips 29, the friction between the inclined roller 13 and the straight roller 12 and the fabric is increased, enhancing the holding effect and flattening effect of the straight roller 12 and the inclined roller 13 on the fabric.

[0044] As Figure 1 、 Figure 4 and Figure 8 shown, the winding member includes a winding base 20. Two winding bases 20 are symmetrically distributed and fixedly connected to the upper side of the base 11. An inclined shaft groove 21 is formed at the upper end of each winding base 20. A winding shaft 23 is rotatably connected in the two shaft grooves 21. A winding sleeve 26 is slidably connected to the winding shaft 23. Two side plates 22 are slidably connected to both ends of the winding sleeve 26 on the winding shaft 23.

[0045] By providing the shaft groove 21, after the winding is completed, the winding sleeve 26 wound with the fabric can be conveniently removed, improving the efficiency.

[0046] As Figure 1 、 Figure 4 and Figure 8 shown, one end of the winding shaft 23 extending out of one of the winding bases 20 is fixedly connected with a first gear 24. A fourth motor 27 is fixedly connected to one side of the winding base 20 below the first gear 24. The power output end of the fourth motor 27 is drivingly connected with a second gear 25 meshing with the first gear 24.

[0047] A highly elastic knitted fabric includes a highly elastic knitted fabric 10. The highly elastic knitted fabric 10 is woven by mixing pure cotton yarn and elastic yarn, and the highly elastic knitted fabric 10 is woven in a 2×2 rib double-sided weft knitting manner.

[0048] In this embodiment, the device is arranged on the discharging side of the weft knitting machine, and the device is connected to the power supply and the control system. The woven fabric passes through the gaps between the two straight rollers 12 and between each group of inclined rollers 13, and finally the fabric is fixed on the winding sleeve 26. At this time, the height of the gaps between the two straight rollers 12 and between each group of inclined rollers 13 is exactly horizontal with the height of the upper edge of the winding sleeve 26. The operator drives the second motor 37 to rotate through the control system, so that the two second sliders 33 move towards each other, thereby changing and adjusting the included angle between the two groups of inclined rollers 13.

[0049] Subsequently, the device is started. The fourth motor 27 drives the reel 23 and the winding sleeve 26 to rotate, gradually winding up the fabric. At the same time, the third motor 36 drives the inclined roller 13 to rotate, and synchronously drives the straight roller 12 to rotate through the universal joint 28. Under the meshing transmission of the two sets of third gears 35, the two inclined rollers 13 rotate in opposite directions with the same rotational speed. Thus, while the two inclined rollers 13 and the two straight rollers 12 hold the fabric, they actively convey the fabric to move towards the winding sleeve 26, and always keep the conveying speed of the straight rollers 12 and the inclined rollers 13 for the fabric the same as the winding speed of the winding sleeve 26. As a result, the tensile force on the fabric stops at the straight rollers 12 and the inclined rollers 13, and the elastic tension on the fabric between the winding component and the straight rollers 12 and the inclined rollers 13 is completely eliminated, so that the wound fabric will not be in an elastically stretched state, avoiding elastic fatigue.

[0050] At the same time, since the fabric far from the winding component is still being pulled, the fabric will produce wrinkles and hourglass-shaped shrinkage in the weft direction. At this time, when the shrunk part of the fabric enters the range of the inclined roller 13 under the conveyance of the straight roller 12 and the inclined roller 13, due to the included angle of the inclined roller 13 relative to the conveying direction, while the inclined roller 13 conveys the fabric, it will apply a component force to both sides of the fabric, gradually flattening the fabric, avoiding the fabric being wound in a state of shrinkage and wrinkles, and improving the winding quality.

[0051] While the winding sleeve 26 gradually winds up the fabric, the thickness of the fabric on the winding sleeve 26 gradually increases. At this time, the control system drives the first motor 18 to rotate, so that the first slider 19 and the second lead screw frame 30 rise synchronously, and thus always keep the conveying direction and the winding direction horizontal, thereby improving the winding effect of the fabric.

[0052] Embodiment 2:

[0053] As shown in Figure 1 、 Figure 4 and Figure 6 Both ends of the two straight rollers 12 are rotatably connected with a stabilizing frame 14, and both ends of the stabilizing frame 14 are slidably connected with both sides of the second lead screw frame 30.

[0054] As a further embodiment, by setting the stabilizing frame 14, the two straight rollers 12 are firmly supported. And when adjusting the included angle between the two sets of inclined rollers 13, the stabilizing frame 14 can adaptively change its position and always support the straight rollers 12, ensuring that the straight rollers 12 can stably hold the fabric, avoiding the fabric from slipping between the two straight rollers 12, and improving the stability of conveying the fabric.
