Description

Technical Field

[0001] The invention relates to a yarn stretching and dyeing device, belonging to the technical field of yarn dyeing. Background Art

[0002] The traditional dyeing process of yarn-dyed fabric has always been produced by the dip dyeing method, which has developed from hand-dyed yarn, hank dyeing to the current package dyeing and warp beam dyeing. At present, package dyeing and warp beam dyeing are used all over the world. Since these methods are intermittent dip dyeing, they are highly polluting. At least 120 tons of water are needed to dye one ton of yarn. The energy consumption is high, about 2000 degrees of electricity and about 8 tons of steam are used per ton of yarn. The equipment investment is large, and the domestic equipment of a 1-ton cylinder of a full stainless steel pressure vessel is about 500,000 yuan, and the Hong Kong Lixin Company in China is more than 1 million yuan. The German investment equipment is even more expensive. Only companies with strong strength can install package and warp beam dyeing equipment.

[0003] There are many problems that need to be solved in yarn dyeing: the yarn cannot be laid out freely like cloth. Once there is no tension, the yarn will break and become messy. Cotton impurities must be removed before yarn dyeing to achieve a certain capillary effect and whiteness. Dyeing requires a certain amount of time to react, which cannot be achieved by general equipment. At the same time, the color absorption of the dye and the changes in the auxiliaries can easily cause the color difference between the head and the tail and the dyeing fastness to fail to meet the requirements. The production cost and product quality must meet or exceed immersion dyeing.

[0004] For example, the invention with patent number 201310453212.0 is a yarn dyeing device, including a dye tank, a vertical side seat with a rotating core is arranged on one side of the dye tank, the rotating core is circular, and a plurality of winding rods are arranged on the rotating core, and each winding rod has the same length from the center of the rotating core. Although the invented yarn dyeing device has a greater space utilization rate, can dye more yarns at one time, is not easy to entangle with each other, and has better dyeing quality, it only performs conventional intermittent dyeing on the yarn and improves the dyeing effect. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a yarn stretching and dyeing device in view of the deficiencies of the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A yarn stretching and dyeing device comprises a dyeing tank and a main turntable, wherein the rotating surface of the main turntable is perpendicular to the dyeing tank, at least four support rods are provided extending outward from the edge of the main turntable, the spacing between two adjacent support rods is the same, an auxiliary turntable is provided on the end of the support rod, the auxiliary turntable is rotatably connected to the end of the support rod, yarn is wound around the two auxiliary turntables of two adjacent support rods, and a counterweight block is provided at the lower part of the auxiliary turntable.

[0008] As a further preferred embodiment, three springs are equidistantly arranged around the edge of the attached turntable, a winding rod is arranged at the end of the spring, the winding rod is perpendicular to the spring, and the yarn is wound around the winding rod; the end side of the support rod has a pin shaft, the pin shaft passes through the center of the attached turntable, the attached turntable rotates on the pin shaft, and a passive cam is arranged at the end of the pin shaft passing through the attached turntable, and the winding rod contacts the passive cam as the attached turntable rotates.

[0009] As a further preferred solution, the rotation speed of the main turntable is 5 turns / min-10 turns / min.

[0010] As a further preferred solution, the length of the support rod is adjustable.

[0011] As a further preferred solution, the weight of the counterweight is adjustable.

[0012] As a further preferred solution, a wave pattern for increasing friction is provided in the length direction of the winding rod.

[0013] Compared with the prior art, the yarn stretching and dyeing device of the present invention can rotate relative to the main turntable through the rotation of the main turntable, while the auxiliary turntable with a counterweight block can rotate relative to the main turntable due to the gravity restraint of the counterweight block, so that the yarn can be dyed in the dye tank. At this time, the yarn wound on the auxiliary turntable can also be wound under the synchronous rotation of the two auxiliary turntables. The yarn is stretched during the activity and all-round dyeing is achieved. The yarn in the stretched state has open yarn fibers and is easy to absorb dye liquid. The yarn is constantly turned over, and the absorbed dye liquid will not drip down, and most of it is contained in the yarn and further integrated into the yarn, so the dyeing effect is better.

[0016] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0017] A yarn stretching and dyeing device of the present invention comprises a dyeing pool 1 and a main turntable 2, wherein the rotating surface of the main turntable 2 is perpendicular to the dyeing pool 1, at least four support rods 3 are provided extending outward from the edge of the main turntable 2, the length of the support rod 3 is adjustable, and the spacing between two adjacent support rods 3 is the same, an auxiliary turntable 4 is provided at the end of the support rod 3, the auxiliary turntable 4 is rotatably connected to the end of the support rod 3, yarn is wound around the two auxiliary turntables 4 of two adjacent support rods 3, and a counterweight block 5 is provided at the lower part of the auxiliary turntable 4, and the weight of the counterweight block 5 is adjustable.

[0018] When in use, the main turntable 2 is arranged on the bracket and is driven to rotate by the motor. The speed of the main turntable 2 is 5 turns / min-10 turns / min, which drives the auxiliary turntables 4 on the multiple support rods 3 to move in a circle. Due to the counterweight block 5 at the lower part of the auxiliary turntable 4, the counterweight block 5 is always kept at the lower part of the auxiliary turntable 4 due to gravity, so that the auxiliary turntable 4 rotates relative to the main turntable 2, and the yarn wound on the two auxiliary turntables 4 can also interact with each other under the synchronous rotation of the two auxiliary turntables 4, similar to the activity form of the crawler track. The yarn moves in circles on the two auxiliary turntables 4 and enters the dyeing tank 1 as the main turntable 2 rotates for a short period of immersion. The yarn then rotates with the main turntable 2, and the yarn is constantly turned over. The adsorbed dye solution will not drain down, and most of it is contained in the yarn and further integrated into the yarn, thereby improving the dyeing effect of the yarn.

[0019] As another embodiment, three springs 6 are equidistantly arranged around the edge of the auxiliary turntable 4, and a winding rod 7 is arranged at the end of the spring 6. The winding rod 7 is perpendicular to the spring 6, and the yarn is wound around the winding rod 7; the end side of the support rod 3 has a pin shaft, the pin shaft passes through the center of the auxiliary turntable 4, the auxiliary turntable 4 rotates on the pin shaft, and a passive cam 8 is arranged at the end of the pin shaft passing through the auxiliary turntable 4, and the winding rod 7 contacts the passive cam 8 as the auxiliary turntable 4 rotates; the auxiliary turntable 4 rotates relative to the main turntable 2 and the passive cam 8, and the inner side of the winding rod 7 intermittently contacts the passive cam 8, and due to the toughness of the spring 6, the winding rod 7 is slightly lifted, and the yarn on the winding rod 7 is stretched, thereby improving the deep adsorption of the yarn to the dye solution.

[0020] Furthermore, a wave pattern is provided along the length direction of the winding rod 7 to increase the friction force.
