Tension control mechanical structure of jigger dyeing machine

 

The jigger is a kind of equipment used for textile dyeing. It has a high degree of automation, is environmentally friendly and energy-saving, and can realize small batches and multiple varieties of dyeing. It is widely used in the textile dyeing industry.
The jigger dyeing machine is divided into the main roller, dye tank, tension frame, guide roller, heating system, circulation system, additional tank system, debatching device, control system, and other parts. Through a series of precise mechanical structures and control systems, the jigger dyeing machine realizes precise control of the fabric dyeing process.

​Among them, the tension frame is a key component of the tension control part of the jigger dyeing machine. Its main function is to ensure the flatness and uniformity of the fabric during the dyeing process by adjusting and controlling the tension of the fabric so as to achieve a higher quality dyeing effect.

​Working principle of tension frame of common jigger dyeing machines

​Working principle of horizontal chevron-shaped type tension frame:
  • The horizontal chevron-shaped tension frame of the jigger dyeing machine mainly maintains balance through the gravity at both ends. The guide rollers on both sides are in contact with the fabric respectively. During the movement of the fabric, the friction between the fabric and the guide roller will cause the tension frame to change in shape. The fabric tension is adjusted by the tension frame’s own gravity and the friction generated by the fabric.
Working principle of a vertically expanded guide roller tension frame:
  • The vertical expansion guide roller tension frame of the jigger dyeing machine mainly relies on springs to adjust the tension. The fabric passes through the lower guide roller, expansion rod and upper guide roller in sequence. During the movement, the fabric will pull the upper guide roller in the direction of the fabric movement, and the spring will pull the swing arm in the opposite direction, so that the fabric can always be in a state of tension. The size of the tension is related to the thickness and elasticity of the fabric. And when the fabric passes through the expansion rod, the arc triangle will expand the fabric to avoid wrinkling and creases.

​Other tension frames of jigger dyeing machines

  • In addition to the above two common tension frames for jigger dyeing machines, various manufacturers have also tried some other forms of tension frames, such as:
  • Pulley tension frame: Adjust fabric tension through pulleys and ropes.
  • Air-floating tension frame: Air-floating bearings are used to support the coiled material, which can provide a more stable tension.
  • Magnetic tension frame: Uses magnetic force to maintain tension.
  • Cylinder tension frame: Use the thrust generated by the cylinder to adjust fabric tension.
  • Motor-type tension frame: adjusts fabric tension through motor drive.
  • Hydraulic tension frame: adjusts fabric tension through a hydraulic system.
  • In addition, there are some special types of tension frames for jigger dyeing machines, such as customized tension frames for specific fabrics or specific process needs. The design and manufacture of these tension frames are usually determined according to specific production requirements and process conditions.
In conclusion, when choosing the tension frame of the jigger dyeing machine, it is necessary to comprehensively consider factors such as the type, thickness, elasticity of the fabric and the requirements of the dyeing process. At the same time, it is also necessary to pay attention to the structural design, material selection, manufacturing accuracy and other aspects of the tension frame to ensure that it can meet production needs and have a long service life.

Fiber Fineness and Tenacity Test

Image
  Test methods explanation We have tested 5 fiber samples using two solutions to test fiber fineness and tenacity: Solution 1 and solution 2. Solution 1 We use YG002C measured the fiber diameter, and YG005S tested the break force and extension. The fiber density is converted to denier from diameter using the formula. Then use the break force divide the density to get the tenacity. Please move to TABLE 1 to view the test result. We have attached YG002C parameter sheet in Appendix 1 and YG005S parameter sheets in Appendix 2. Solution 2 We use ZK100F measured the fiber density, and YG005X tested the break force, extension, and tenacity. Please move to TABLE 2 to view the test result. We have attached ZK100F parameter sheet in Appendix 3 and YG005X parameter sheet in Appendix 4. A better solution for fiber density and tenacity testing  We also have a YG005XD AUTOMATIC FIBER TENSILE AND FINENESS TEST SYSTEM, which has integrated function of ZK100F and YG005X; it is equipped wi...

Introduction of Sizing

Image
  Sizing is the process of applying size to warp yarns to improve their weavability. Weavability refers to the ability of warp yarns to withstand repeated friction, stretching, bending and other effects of stop sheets, heddles, reeds, etc. on a loom without causing excessive fluffing or even breakage. Unsized single yarn fibers do not adhere tightly to each other and have more hairiness on the surface, making it difficult to weave. After sizing, part of the sizing liquid penetrates between the fibers, and the other part adheres to the surface of the warp yarn. The sizing that mainly involves the penetration of the slurry into the fibers is called penetrating sizing, and the sizing that mainly relies on the slurry adhering to the surface of the warp yarns is called covering sizing. Ancient manual sizing involves spreading the warp yarns into sheets, applying paste with a brush or reed, drying and then winding them into weaving beams. Wang Zhen’s “Nongshu” of the Yuan Dynasty contain...

Selection of materials for jigger dyeing machine parts

Image
In the textile industry, the jigger dyeing machine is a key textile printing and dyeing equipment. The selection of its main manufacturing material has a vital impact on the performance, durability, and dyeing effect of the equipment. Stainless steel is one of the most commonly used materials in modern dye jigger manufacturing, especially 304 and 316L. Material selection for each component of the jigger dyeing machine The jigger dyeing machine is composed of a frame, an electric control cabinet, a vessel/top cover, a circulation system, a dye bath, a main roller, a guide roller, a tension frame, an additional tank, a debatching device, and other parts. More details about jigger dyeing machine in our company No contact with dye solution ​ For parts that are not in contact with the dye solution, the main consideration when choosing the manufacturing material is the use environment of the equipment. Generally speaking, the environment of the dyeing factory is harsh. We recommend using 304...
