Description

Technical Field

[0001] This utility model relates to the field of yarn dyeing technology, specifically to a high-efficiency leveling device for polyester low-elasticity yarn. Background Technology

[0002] Polyester low-elasticity yarn is a type of textured polyester filament made from polyester chips (PET) through high-speed spinning and drawing false twisting processes. It has low elasticity, high bulkiness, soft hand feel, and excellent dyeing properties, and is widely used in textiles, clothing, home furnishings and other fields. After production, polyester low-elasticity yarn can be dyed in a dyeing box according to requirements to improve the color richness of polyester low-elasticity yarn.

[0003] Existing polyester low-elasticity yarn dyeing devices, such as the polyester yarn low-elasticity yarn dyeing device disclosed in publication number CN221254902U, although they can evenly separate the yarn through guide wheels distributed on the rotating shaft so that the yarn will not knot or intertwine during the dyeing process, make it inconvenient to extend the dyeing path of the polyester low-elasticity yarn in the dyeing box, and also inconvenient to perform pre-dyeing and re-dyeing before and after dyeing, resulting in poor dyeing effect. Therefore, we propose a high-efficiency even dyeing device for polyester low-elasticity yarn. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a high-efficiency leveling device for polyester low-elasticity yarn.

[0024] Example 1:

[0025] Combination Figure 1-3 As shown, this utility model provides a high-efficiency even dyeing device for polyester low-elasticity yarn, comprising: a dyeing box 100 and a dyeing assembly 200; the dyeing box 100 includes a feed roller 101 and a discharge roller 102 fixedly installed at its two ends respectively; the dyeing assembly 200 includes a movable box 201 movably installed in the center of the dyeing box 100, an upper conveying roller 202 fixedly installed at the bottom of the movable box 201, lower conveying rollers 203 fixedly installed on both sides of the bottom of the dyeing box 100, a liquid suction box 204 fixedly installed on both sides of the bottom of the movable box 201, a liquid spraying box 205 fixedly installed at both ends of the movable box 201, and a conveying pump 206 fixedly installed on both sides of the movable box 201. Cylinders 207 are fixedly installed at both ends of the box 100. A connecting plate 208 is fixedly installed between the top of the cylinder 207 and the top of the movable box 201. A suction pipe 209 is fixedly connected between the delivery pump 206 and the suction box 204. A spray pipe 210 is fixedly connected between the delivery pump 206 and the spray box 205. Fixed ears 211 are also fixedly installed on the top of the movable box 201. Positioning posts 212 are fixedly installed at the bottom of the fixed ears 211. Positioning holes 213 are also arranged in the dyeing box 100, and the positioning holes 213 and the positioning posts 212 are matched. The suction box 204 is located directly above the lower delivery roller 203. There are three sets of upper delivery rollers 202.

[0026] Specifically, polyester low-elasticity yarn is a type of textured polyester filament made from polyester chips through high-speed spinning and drawing false twisting processes. After production, polyester low-elasticity yarn can be dyed as needed to improve its color richness. The movable box 201, driven by cylinder 207 inside the dyeing box 100, can be pressed into the dyeing box 100 before dyeing, thereby forming a U-shaped structure in the dye liquor within the dyeing box 100 to extend the dyeing path of the polyester low-elasticity yarn. Simultaneously, the upper conveying roller 202 at the bottom of the movable box 201 can also cooperate with the lower conveying rollers 203 on both sides of the dyeing box 100 to form a wavy conveying path during dyeing, further increasing the contact area with the dye liquor. The spray boxes 205 installed at both ends inside the movable box 201 can also draw liquid from the dyeing box 100 via the conveying pump 206. The dye liquor is used for pre-dyeing before dyeing polyester low-elasticity yarn and for re-dyeing after dyeing, thereby improving the dyeing uniformity of polyester low-elasticity yarn. The liquid suction box 204 located at the top of the lower conveyor roller 203 inside the dyeing box 100 can also increase the fluidity of the dye liquor above the lower conveyor roller 203 when it sucks up the dye liquor in the dyeing box 100, thereby improving the dyeing effect of the polyester low-elasticity yarn being conveyed on the lower conveyor roller 203. The movable box 201, which is easily lifted by the cylinder 207 inside the dyeing box 100, can also facilitate the yarn laying of polyester low-elasticity yarn before dyeing. After the movable box 201 is lifted, the polyester low-elasticity yarn can be passed through the bottom of the movable box 201 to complete the yarn laying of polyester low-elasticity yarn. The positioning column 212 installed in the positioning hole 213 on the movable box 201 can be used to position the movable box 201 in the downward movement position and also ensure the stability of the movable box 201 during the downward movement.

[0027] Working principle and usage process of this utility model:

[0028] During the dyeing of polyester low-elasticity yarn, the cylinders 207 at both ends are activated to lower the movable box 201 in the center of the dyeing box 100. As the movable box 201 moves downward, the positioning post 212 at the outer end moves into the positioning hole 213 inside the dyeing box 100 to ensure the positioning and stability of the movable box 201 during its downward movement. After the movable box 201 has moved downward, the dye liquor in the dyeing box 100 will flow to both ends of the movable box 201 under pressure, thus forming a U-shaped structure. At this point, the polyester low-elasticity yarn can be conveyed. After being conveyed by the feed roller 101, the polyester low-elasticity yarn is conveyed to the upper conveyor roller 202 and lower conveyor roller 202 inside the dyeing box 100. A wave-shaped conveying structure is formed between the rollers 203 and between the upper conveying roller 202 and the lower conveying roller 203 to cooperate with the U-shaped dye liquor in the dyeing box 100, increasing the path and contact area during the dyeing of polyester low elastic yarn. At the same time, the conveying pumps 206 at both ends of the movable box 201 will draw the dye liquor from the bottom of the dyeing box 100 through the liquid suction box 204, and spray the drawn dye liquor through the spray boxes 205 at both ends of the movable box 201 to perform uniform spray pre-dyeing of polyester low elastic yarn before dyeing at the front end of the feed roller 101 and uniform spray re-dyeing of polyester low elastic yarn after dyeing at the rear end of the discharge roller 102, so as to improve the efficiency and uniformity of polyester low elastic yarn dyeing in the dyeing box 100.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
