Description

Technical Field

[0001] This utility model relates to the field of cold dyeing machine technology, specifically a cold dyeing machine with a tensioning function. Background Technology

[0002] In cold dyeing machines, the tensioning assembly is typically located at a critical point in the dyeing process, generally between the cold water roller drive section and the uniform rolling section. The tensioning assembly generally includes a base plate, a tensioning frame, a bearing mounting section, a tensioning roller, and a torque motor. The tensioning frame is rotatable under the drive of the torque motor, and the tension force is changed by adjusting the tension on the fabric.

[0003] However, electrical equipment generally has the following drawbacks in use: it is expensive and requires the design of sensors, controllers, and other structures; while torque motors can adjust tension over a wide range, their response speed may not meet production requirements. For example, in high-speed operating equipment, when the fabric tension suddenly changes, the torque motor may need time to adjust its output torque to reach a new equilibrium state, which may cause brief tension fluctuations in the fabric and affect product quality. Therefore, a cold dyeing machine with tensioning function is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a cold dyeing machine with a tensioning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold dyeing machine with a tensioning function, comprising a fixed plate, on both sides of the fixed plate surface being movably arranged with guide rollers via rotating shafts, and a tensioning mechanism for tensioning fabric being arranged between the guide rollers on the fixed plate surface, the tensioning mechanism comprising a first mounting component, a rotating arm, a tensioning roller, a crossbar, a connecting arm, a second mounting component, a connecting shaft, and a damping cylinder, the first mounting component being fixedly arranged on the fixed plate surface, the rotating arm being movably arranged on the surface of the first mounting component via rotating shafts, the tensioning roller being movably arranged at one end of the rotating arm via rotating shafts, the crossbar being fixedly arranged at the other end of the rotating arm, the connecting arm being fixedly arranged at the upper middle part of the crossbar, the second mounting component being fixedly arranged on one side of the first mounting component on the fixed plate surface, the connecting shaft being arranged between the second mounting components, and the damping cylinder being arranged between the connecting shaft and the connecting arm.

[0006] Preferably, one end of the damping cylinder is movably connected to the connecting arm via a rotating shaft and a bearing, and the other end of the damping cylinder is movably connected to the connecting shaft via a rotating shaft. Both ends of the damping cylinder need to be movably connected to ensure that the rotating arm can rotate normally so that the tensioning roller can tension the fabric.

[0007] Preferably, a threaded sleeve is fixedly provided on one side of the outer surface of the damping cylinder, and a limit ring is fixedly provided on the other side of the outer surface of the damping cylinder. A rotating ring is provided on the outer surface of the threaded sleeve by means of a threaded engagement. A spring is sleeved between the rotating ring and the limit ring. By adjusting the distance between the limit ring and the rotating ring, the initial compression degree of the spring can be adjusted, thereby adjusting the tension force of the tensioning roller on the fabric.

[0008] Preferably, the first mounting component and the second mounting component have mounting holes on their outer surfaces, and the first mounting component and the second mounting component can be fixedly installed at the target position by means of the mounting holes and locking screws.

[0009] Preferably, the damping cylinder is equipped with damping oil. The damping oil can ensure that the spring (14) is damped when it extends and retracts, and will not shake continuously, affecting the tension of the tensioning roller.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a cold dyeing machine with a tensioning function, including a fixed plate 1. Guide rollers 2 are movably arranged on both sides of the surface of the fixed plate 1 via rotating shafts. A tensioning mechanism for tensioning fabric is arranged between the guide rollers 2 on the surface of the fixed plate 1. The tensioning mechanism includes a first mounting component 3, a rotating arm 4, a tensioning roller 5, a crossbar 6, a connecting arm 7, a second mounting component 8, a connecting shaft 9, and a damping cylinder 10. The first mounting component 3 is fixedly arranged on the surface of the fixed plate 1. The rotating arm 4 is movably arranged on the surface of the first mounting component 3 via rotating shafts. The tensioning roller 5 is movably arranged at one end of the rotating arm 4 via rotating shafts. The crossbar 6 is fixedly arranged at the other end of the rotating arm 4. The connecting arm 7 is fixedly arranged at the upper middle part of the crossbar 6. The second mounting component 8 is fixedly arranged on one side of the first mounting component 3 on the surface of the fixed plate 1. The connecting shaft 9 is arranged between the second mounting components 8. The damping cylinder 10 is arranged between the connecting shaft 9 and the connecting arm 7.

[0019] One end of the damping cylinder 10 is movably connected to the connecting arm 7 via a rotating shaft and a bearing, and the other end of the damping cylinder 10 is movably connected to the connecting shaft 9 via a rotating shaft. Both ends of the damping cylinder 10 need to be movably connected to ensure that the rotating arm 4 can rotate normally so that the tensioning roller 5 can tension the fabric.

[0020] A threaded sleeve 11 is fixedly provided on one side of the outer surface of the damping cylinder 10, and a limit ring 12 is fixedly provided on the other side of the outer surface of the damping cylinder 10. A rotating ring 13 is provided on the outer surface of the threaded sleeve 11 by threaded engagement. A spring 14 is sleeved between the rotating ring 13 and the limit ring 12. By adjusting the distance between the limit ring 12 and the rotating ring 13, the initial compression degree of the spring 14 can be adjusted, thereby adjusting the tension force of the tensioning roller 5 on the fabric.

[0021] The first mounting component 3 and the second mounting component 8 have mounting holes 14 on their outer surfaces. The first mounting component 3 and the second mounting component 8 can be fixedly installed at the target position by using the mounting holes 14 and locking screws.

[0022] The damping cylinder 10 is equipped with damping oil, which ensures that the spring 14 is damped when it extends and retracts, and will not vibrate continuously, thus affecting the tension of the tensioning roller 5.

[0023] Working Principle: This device effectively and automatically maintains fabric tension during cold dyeing, offering high tensioning efficiency and low cost, making it easy to promote and use. The tensioning principle is as follows: When the fabric loosens during transport, spring 14 quickly springs up according to the looseness, causing damping cylinder 10 to extend and simultaneously pushing rotating arm 4 to rotate. This causes tensioning roller 5 to further tension the fabric downwards. Conversely, if the fabric tension is high, the tensioning roller 5 is pulled in the opposite direction, causing rotating arm 4 to rotate and move tensioning roller 5 upwards, releasing more fabric to meet the fabric tension. Thus, this device achieves an adaptive tensioning effect. Furthermore, during use, the initial compression of spring 14 can be adjusted by spirally adjusting the distance between limiting ring 12 and rotating ring 13, thereby adjusting the tensioning force of tensioning roller 5 on the fabric and improving the device's performance.
