[0028] Specifically, the first rotating shaft 7 and the second rotating shaft 8 located in the same vertical direction form a transmission structure, and multiple transmission structures are arranged in sequence along the movement direction of the ribbon. In order for the baking oven 4 to dry as many ribbons as possible, the ribbon will be wound back and forth on the first rotating shaft 7 and the second rotating shaft 8 of a transmission structure, thereby increasing the length of the ribbon accommodated in the baking oven 4. The multiple sections of ribbon wound back and forth on a first rotating shaft 7 will also be correspondingly wound around the multi-section cylinder 10 that is sleeved outside this transmission structure. In the actual production process, the ribbon in the baking box 4 is dried by the baking mechanism 5. While drying, the second driving assembly 9 drives the plurality of second rotating shafts 8 to rotate along the conveying direction of the ribbon, and at least two different speeds exist between the plurality of second rotating shafts 8. In addition, the speed of the second rotating shaft 8 gradually increases along the conveying direction of the ribbon. The cooperation of the second rotating shaft 8 with a fast speed and the first rotating shaft 7 will pull the ribbon forward relative to the second rotating shaft 8 with a slow speed and the first rotating shaft 7. The differential rotation transmission structure will cooperate with the differential drawing device 2 to draw the ribbon, and then the drawing compensation will be performed while the ribbon is drying to avoid excessive retraction of the ribbon. During stretching, when the stress of the ribbons wound on different transmission structures is inconsistent, the ribbons, driven by their own tensile stress or tension, will respectively drive the plurality of sections of the barrel 10 to rotate relative to the first rotating shaft 7 or / and the second rotating shaft 8 in the opposite direction, so that the tensile stress or tension of the ribbon is consistent, so that the internal force of the ribbons wound on different transmission structures is balanced, and then the ribbon is extended or stretched in a balanced manner. The belt storage device 101, dyeing tank 102 and color fixing machine 103 of the utility model are convenient for the production and processing of the belt, and the belt can be stretched while drying the belt, and the shrinkage rate of the belt during drying is synchronously controlled, which improves the production efficiency of the belt, simplifies the structure of the utility model, and makes the structure more compact. Moreover, by adding a cylindrical structure 6, when the belt is stretched or extended, the belt can drive the cylinder 10 to rotate relative to the first rotating shaft 7 or the second rotating shaft 8 in the opposite direction, thereby balancing the tensile stress or tension of the belt, so that the tension or tensile stress of the belt at different positions is consistent, achieving buffering during the stretching process of the belt, and the drying effect of the belt is good, and the belt quality is good.
[0029] Preferably, the second drive assembly 9 includes three second drivers 11, and the second drivers 11 are used to synchronously drive at least two second rotating shafts 8 to rotate. The number of the second rotating shafts 8 and the first rotating shaft 7 is set to seven, and the number of the cylindrical structures 6 is set to six, and the six cylindrical structures 6 are respectively sleeved on the three middle second rotating shafts 8 and the first rotating shaft 7. In actual use, one second driver 11 can be selected to drive one second rotating shaft 8 to rotate, or three second drivers 11 can be selected to respectively drive two or three second rotating shafts 8 connected to the second second drivers 11 to rotate. Different second drivers 11 output different powers, so that the rotation speeds of the second rotating shafts 8 connected to different second drivers 11 are different, so that the second rotating shaft 8 drives the webbing to move at a differential speed. The second driver 11 can adopt an existing mechanism of motor and reducer cooperation, and the speed of the second rotating shaft 8 can be adjusted by adjusting the output power of the reducer or the motor.
[0030] Furthermore, the ribbon production line is also provided with a quenching tank 104, a steamer box 105 and a washing bucket 106 in sequence along the conveying direction of the ribbon. The quenching tank 104 is used to cool and flatten the dried ribbon, the steamer box 105 is used to steam and pre-shrink the ribbon; the washing bucket 106 is used to wash the ribbon.
[0031] In actual use, the quenching tank 104 quenches the ribbon, which can greatly improve the quality of the ribbon, prevent the ribbon from breaking, reduce problems in the production process, and promote the formation of fibers. Then the steamer 105 steams and pre-shrinks the ribbon, which improves the bending performance, air permeability and color fastness of the fabric. Then the washing bucket 106 washes the fabric to remove the original paste and floating color, enhance the fabric feel, show clear and bright patterns, and ensure good color fastness.
[0032] Furthermore, the ribbon production line is also provided with a pre-drying box 107, a cooling box 108, a chemical tank 109, a drying box 110 and a belt-taking mechanism 111 in sequence along the conveying direction of the ribbon. The pre-drying box 107 is used for preliminary dehydration or drying of the washed ribbon, the cooling box 108 is used for cooling the ribbon, the chemical tank 109 is used for fixing the color of the ribbon, the drying box 110 is used for drying the ribbon, and the belt-taking mechanism 111 is used for winding up the ribbon.
[0033] In actual use, the washed ribbon is preliminarily dehydrated by the pre-drying box 107, then cooled and preliminarily fixed by the cooling box 108, then fixed by the chemical tank 109, and finally dried by the drying box 110 and wound by the winding mechanism 111, thereby completing the production of the ribbon. The ribbon production line can continuously process and produce the ribbon, and the produced ribbon has good quality and high color fastness.
[0034] Furthermore, the cylindrical structure 6 also includes two positioning rings 12, which are respectively located on both sides of the multi-section cylinder 10 of the cylindrical structure 6; the positioning rings 12 are respectively sleeved outside the first rotating shaft 7 and / or the second rotating shaft 8 and are respectively radially fixed to the first rotating shaft 7 and / or the second rotating shaft 8.
[0035] During actual use, the two positioning rings 12 can be respectively clamped on the first rotating shaft 7 or the second rotating shaft 8, and the multi-section cylinder 10 is clamped in the middle by the two positioning rings 12 to prevent the cylinder 10 from radially sliding relative to the first rotating shaft 7 or the second rotating shaft 8, thereby improving the stability of the webbing wrapped around the outside of the cylinder 10.
[0036] Furthermore, the tension adjustment assembly 3 further includes a tilt adjustment device 31 , and the tilt adjustment device 31 is used to adjust the angles of the first rotating shaft 7 and the second rotating shaft 8 in the oven 4 , respectively.
[0037] During actual use, since the webbing is repeatedly spirally wound on the same first rotating shaft 7 or the second rotating shaft 8, when the webbing is pulled forward by the first rotating shaft 7 and the second rotating shaft 8, in order to avoid the webbing from crossing and overlapping on the first rotating shaft 7 or the second rotating shaft 8, the first rotating shaft 7 or the second rotating shaft 8 is adjusted to a certain inclination angle by the inclination adjustment device 31, and the possible overlap of the webbing is eliminated by inclination of the first rotating shaft 7 and the second rotating shaft 8, thereby avoiding the problem of webbing overlap and webbing surface damage caused by contact under high temperature.
[0038] Furthermore, the tilt adjustment device 31 includes an adjustment frame 32 arranged on the baking oven 4, a plurality of adjustment rods 33 threadedly connected to the adjustment frame 32, a plurality of adjustment seats 35 respectively connected to the adjustment frame 32 for lifting and sliding, and a plurality of automatic self-aligning bearings 34, wherein the plurality of automatic self-aligning bearings 34 are respectively arranged in the adjustment seats 35, and the two ends of the first rotating shaft 7 and the second rotating shaft 8 can be rotatably connected to the two adjustment seats 35 via two automatic self-aligning bearings 34 respectively; one end of the adjustment rod 33 passes through the adjustment frame 32 and is supported at the bottom end of the adjustment seat 35.
[0039] Specifically, a plurality of adjustment rods 33 and a plurality of adjustment seats 35 are arranged in one-to-one correspondence; the automatic self-aligning bearing 34 can adopt an existing tapered sleeve type automatic self-aligning roller bearing, which will not be described in detail here. In actual use, the other end of the hand-held adjustment rod 33 drives the adjustment rod 33 to rotate relative to the adjustment frame 32, so that the length of the other end of the adjustment rod 33 extending out of the adjustment frame 32 increases and pushes the adjustment seat 35 upward, so that the adjustment seat 35, the automatic self-aligning bearing 34 and one end of the first rotating shaft 7 or the second rotating shaft 8 are tilted upward relative to the adjustment seat 35, and the other ends of the first rotating shaft 7 and the second rotating shaft 8 can be adaptively tilted relative to the automatic self-aligning bearing 34, thereby completing the angle adjustment of the first rotating shaft 7 and the second rotating shaft 8. The tilt adjustment device 31 has a simple structure and low production cost.
[0040] Furthermore, the differential drawing device 2 includes two differential roller assemblies 21 respectively located on both sides of the baking oven 4; along the conveying direction of the ribbon, the ribbon is sequentially wound around a differential roller assembly 21, a tension adjustment assembly 3 and another differential roller assembly 21.
[0041] Specifically, the speed of the webbing driven by a differential roller assembly 21, a tension adjustment assembly 3 and another differential roller assembly 21 is set to decrease step by step, so that the speed of the webbing at different positions along the conveying direction of the webbing decreases step by step. Through the cooperation of two differential roller assemblies 21 and differential roller assembly 21, one differential roller assembly 21 will generate an active forward pulling force on the webbing, and the other differential roller assembly 21 will generate a pulling force on the webbing opposite to the forward direction of the webbing. Through the cooperation of multiple sets of transmission structures, the webbing between the two differential roller assemblies 21 is buffered or transitionally stretched, and the tension in the webbing stretching process is balanced, thereby achieving stable extension of the webbing.
[0042] Furthermore, the differential roller assembly 21 includes a roller mounting bracket 22 , a plurality of roller shafts 23 rotatably disposed on the roller mounting bracket 22 , and a first driving assembly 24 for driving the plurality of roller shafts 23 to rotate relative to the roller mounting bracket 22 .
[0043] In actual use, the first drive assembly 24 can adopt the existing gear belt transmission structure, the drive structure of the reducer and the motor. The number of roller shafts 23 of a differential roller assembly 21 that actively pulls the webbing forward is greater than the number of roller shafts 23 of another differential roller assembly 21, so that the differential roller assembly 21 can stably pull the webbing forward, and avoid the resistance of the webbing relative to the previous differential roller assembly 21 being greater than the resistance of the other differential roller assembly 21, so that the differential roller assembly 21 slips in the process of pulling the webbing forward. The differential roller assembly 21 has a simple structure and is easy to install, and it is convenient to stretch the webbing through the cooperation of the front and rear differential roller assemblies 21.
[0044] Specifically, the baking mechanism 5 can adopt an existing baking structure, which will not be described in detail here. The pre-drying box 107 and the drying box 110 have the same or similar structures as the color fixing machine 103, which will not be described in detail here.

[0046] A method for producing a webbing, comprising the webbing production line described above, the method for producing the webbing is as follows:
[0047] Step 1: The ribbon storage device 101 supplies the ribbon to the dyeing tank 102, the dyeing tank 102 dyes the ribbon, and the fixing agent fixes the color of the ribbon;
[0048] Step 2: The ribbon is quenched in a quench box, and then steamed and pre-shrunk in a steam box 105; and then the ribbon is washed in a washing bucket 106.
[0049] Step three: preliminarily dehydrate or dry the washed ribbon through the pre-drying box 107, cool the ribbon through the cooling box 108, fix the color of the ribbon through the chemical tank 109, dry the ribbon through the drying box 110, and reel the ribbon through the reeling mechanism 111.
[0050] The webbing produced through the above steps is of good quality and high color fastness.
[0051] All technical features in this embodiment can be freely combined according to actual needs.
