Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a tension frame of a dyeing machine. Background Art

[0002] Dyeing is a crucial step in the textile production process. Having the right dyeing aid ensures greater efficiency. The emergence of the bundle dyeing machine has elevated yarn dyeing to a new level, achieving excellent dye fastness, virtually no yarn breakage, and simple, user-friendly operation.

[0003] However, with the continuous increase in market demand, ordinary dyeing machines are equipped with a tension component that can move up and down inside the tension frame. The outer wall of the tension component is in contact with the outer wall of the yarn, so that the loose part of the yarn is supported by the tension component. However, in this process, the tension component and the yarn are in a relatively independent state. When the tension component changes its position, the loose yarn will become disconnected or misaligned with the tension component, causing the yarn to be entangled and broken. Utility Model Content

[0004] The purpose of the utility model is to provide a tension frame of a dyeing machine. By means of an adjusting mechanism and a positioning component, the connection position between the tension frame and the yarn can be limited first. The adjusting mechanism assists the use of a sensing component so that the rotation angle of the adjusting mechanism can be automatically controlled, thereby enabling the tension frame to automatically adjust the tension of the yarn, so that the yarn will not be entangled during the conveying process, thereby ensuring that the yarn runs in an orderly manner.

[0031] The inner wall of the tension frame body 1 is provided with an adjustment mechanism 3 for adjusting the tension of the tension roller 2 and the support shaft 21. The adjustment mechanism 3 includes a swing arm 31. The two sets of swing arms 31 are movably hinged to the two ends of the tension roller 2 and the support shaft 21 respectively, and the connecting arm 32 is rotatably connected to one end of the swing arm 31. A film cylinder 33 is provided on the top end surface of the tension frame body 1, and one end of the film cylinder 33 is movably hinged to one end of the connecting arm 32. The yarn first passes through the first threading tube 11, then passes between the tension roller 2 and the support shaft 21, and then passes through the outer wall of the second threading tube 12. When the yarn becomes loose during transportation, the film cylinder 33 is opened to make the film cylinder 33 extend and retract, thereby driving the swing arm 31 connected at one end thereof to move, so that the swing arm 31 and the tension roller 2 and the support shaft 21 arranged at the swing arm 31 are tilted at a certain angle, thereby tensioning a part of the yarn passing therebetween, so that the yarn will not be entangled during transportation.

Both ends of the support shaft 21 are fixedly connected to the limit rod 343, and the limit rod 343 extends to one end outside the tension frame body 1 and is connected to one end of the angle sensor 342. The adjustment mechanism 3 cooperates with the angle sensor 342 installed on one side to automatically control the rotation angle of the adjustment mechanism 3, so that the tension frame can automatically adjust the tension of the yarn, so that the yarn will not be entangled during the transportation process, and the yarn direction is guaranteed to be orderly.
