Description

Technical Field

[0001] The utility model relates to the field of textiles, in particular to a pulling device for improving the knitting quality of ultra-fine denier silk dyed test socks. Background Art

[0002] The pulling device of the experimental knitting machine plays the role of feeding and stretching the socks. The existing pulling device consists of a cam, a push rod, a pawl, a ratchet and two rollers. The cam rotates one circle, and the ratchet is pushed by the push rod, which drives the roller to rotate through an angle, so that the socks can be pulled down normally. However, the ratchet has the disadvantages of high noise, large impact and wear, and a short service life. The screws at the connection between the push rod and the pawl are easy to loosen, resulting in the roller not being able to rotate smoothly, so that the socks cannot be pulled down smoothly. The socks pulled directly from the knitting machine often have poor pulling. The socks with poor pulling are fluffy, uneven, and have raised floating yarns, which leads to color judgment after high-temperature dyeing. Personnel may make misjudgments and easily identify yarn with quality problems as normal yarn, which makes it impossible to guarantee product quality. Color judges may also identify normal yarn as abnormal yarn, thereby increasing production costs. In actual operation, in order to avoid human misjudgment, companies will rework and knit products with sock knitting quality problems. Rework wastes time, consumes manpower, occupies equipment resources, and increases labor costs. Therefore, there is an urgent need for a pulling device that improves the knitting quality of ultra-fine denier yarn dyeing test socks. The socks can be stably pulled out from the test knitting machine to ensure the flatness of the sock surface, which is convenient for color judges to judge the color of the socks, saving production costs and improving production efficiency.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0024] A pulling device for improving the knitting quality of ultra-fine denier dyed test socks, comprising a lower bracket, fixed bearing seats are provided on both sides of the lower bracket, a first roller is rotatably connected between the two fixed bearing seats, an adjustable bearing seat that can be adjusted horizontally on the lower bracket is provided on one side of the two fixed bearing seats, at least one spring is provided between the fixed bearing seat and the adjustable bearing seat on the same side, a second roller is rotatably connected between the two adjustable bearing seats, an adjusting bolt for adjusting the adjustable bearing seat is provided on one side of the two adjustable bearing seats, an upper bracket is provided above the lower bracket, a limiting device is provided on the upper bracket, the first roller is connected to a first motor, the second roller is connected to a second motor, the first motor and the second roller are connected The two motors rotate at the same speed. The first motor drives the first roller to rotate, and the second motor drives the second roller to rotate. The socks first pass through the limiting device on the upper bracket. The limiting device can preliminarily limit the socks. The socks that have passed the preliminarily limited position pass between the first roller and the second roller. The first roller rotates clockwise and the second roller rotates counterclockwise. The socks are stably drafted downward by the second roller and the second roller. The motor has strong stability, and the limiting device on the upper bracket limits the socks, so that the surface of the drafted socks is smooth and flat, without raised floating yarns. The operator can accurately identify the dyed socks, effectively avoiding losses caused by color judgment errors.

[0025] Adjustment screw holes matching the adjusting bolts are provided on both sides of the lower bracket, and the two adjusting screw holes are provided with internal threads, and the two adjusting bolts are provided with external threads matching the internal threads. The ends of the two adjusting bolts conflict with the matching adjustable bearing seats, and slide grooves are provided on both sides of the lower bracket. The two adjustable bearing seats are slidably connected in the matching slide grooves. By screwing the adjusting bolts, the adjustable bearing seats can be pushed to slide in the slide grooves, changing the distance between the adjustable bearing seats and the fixed bearing seats, thereby adjusting the distance between the first roller and the second roller. If there are quality problems with the socks during the production process, the distance between the first roller and the second roller can be adjusted in time, thereby adjusting the pressing force of the two rollers on the socks to achieve uniform and stable drafting of the socks.

[0026] The surface material of the first roller and the second roller are both rubber. The texture of the sock tube is soft and the rubber material has good elasticity, which enables the roller to undergo elastic deformation when subjected to force, thereby better adapting to production needs. The rubber material also has better wear resistance and aging resistance, and can maintain stable performance for a long time.

[0027] There are three springs, which are vertically and evenly arranged between the fixed bearing seat and the adjustable bearing seat. The springs can ensure that there is elastic force between the two rollers, so that the two rollers can undergo elastic deformation when subjected to force, which can better adapt to production needs and prevent quality problems in the socks due to excessive pressure between the two rollers during the stretching process.

[0028] The limiting device includes two limiting bases, which are slidably connected to both sides of the upper bracket. Each limiting base is provided with a limiting plate at one end away from the upper bracket. A limiting channel is formed between the two limiting plates. The setting direction of the two limiting plates is consistent with the drafting direction of the socks. The socks pass between the limiting channels to achieve preliminary limiting. After passing through the limiting channel, the socks enter between the two rollers, which can make the drafting of the socks more stable and improve the quality of the socks.

[0029] Slide grooves are provided on both sides of the upper bracket, and each limit base is connected to the slide groove by sliding. A limit groove is provided on one side of each limit plate. A limit hole is provided on one side of the upper bracket located on the limit groove, and a limit bolt is provided in each limit hole. An internal thread matching the limit bolt is provided in each limit hole. Each limit bolt has an arc structure near one end of the limit groove, and the arc structure conflicts with the limit groove. After sliding the limit base to the position to be fixed, the limit bolt is turned, and the arc structure at the end of the limit bolt can conflict in the limit groove, thereby realizing the limitation of the limit base. For different production conditions, the distance between the two limit plates can be adjusted to adapt to different production needs.

[0030] How it works

[0031] When using this device, it is connected to the sock outlet of the test hosiery knitting machine. First, the sock is passed through the limiting device for limitation. The sock is a long strip structure. After passing through the limiting device, the sock passes between the first roller and the second roller. The distance between the two rollers is adjusted by using two adjusting bolts. The first motor and the second motor are turned on, the first roller rotates clockwise, and the second roller rotates counterclockwise. The sock is evenly stretched out between the first roller and the second roller. When the sock is entangled, the first motor and the second motor are controlled to reverse, the first roller rotates counterclockwise, and the second roller rotates clockwise to take out the entangled sock. This drafting device has a simple structure, can improve production efficiency, and improve the sock drafting quality.
