Description

Technical Field

[0001] The utility model relates to the technical field of yarn guide and feeding devices, in particular to a yarn guide and feeding device for a seamless underwear machine which improves the adaptability of the device. Background Art

[0002] With the rapid development of the textile industry and consumers' increasing demands for clothing quality, seamless underwear, as a comfortable, aesthetically pleasing, and highly functional garment, is gaining market favor. As a key piece of equipment in the production of this type of product, the performance and technical level of seamless underwear machines directly determine product quality and production efficiency. The yarn guide and feeding device, a core component of seamless underwear machines, plays a crucial role in ensuring accurate yarn delivery and knitting quality through its stability and adaptability.

[0003] Chinese patent CN221810443U discloses a yarn guide and feeding device for a seamless underwear machine. The device comprises a support plate, two sets of adjustable yarn guide assemblies disposed at the left end of the support plate, and the adjustable yarn guide assemblies are used to control the yarn guide spacing according to the situation. A vibrating dust removal assembly is disposed in the middle of the adjustable yarn guide assemblies, and the vibrating dust removal assembly is used to remove dust from the yarn surface. The patent uses the reciprocating vibration of the dust removal plate to cause the yarn to reciprocate, thereby removing dust from the yarn.

[0004] Currently, some existing technologies have proposed solutions to the problem of yarn dust removal. For example, one technical solution uses a dust removal plate and reciprocating vibration to drive the yarn back and forth, attempting to use this vibration method to remove dust from the yarn. However, this method of reciprocating yarn vibration to remove dust has obvious drawbacks. On the one hand, its dust removal effect is limited. Due to the relatively simple vibration method, the vibration amplitude and frequency are subject to certain restrictions, which cannot completely remove dust from the yarn surface. In particular, the removal effect is poor for some highly adherent dust, resulting in some dust residue. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1-6 As shown, the utility model provides a yarn guiding and feeding device for a seamless underwear machine with improved adaptability, comprising: a main body 1; a yarn gathering component 2, which is arranged on the top of the main body 1 and in the yarn conveying direction, and the yarn gathering component 2 is used to gather multiple strands of yarn into one strand; a yarn adjusting component 3, which is arranged at the bottom of the main body 1 and is used to adjust the distance between each strand of yarn; a dust removal component 4, which is arranged at the center position of the top of the main body 1 and can remove dust on the yarn; the dust removal component 4 includes a dust removal box 41 installed on the top of the main body 1, and a plurality of brushes 42 that can contact the yarn are distributed above and below the inside of the dust removal box 41, and the dust removal component 4 also includes an adsorption device that can be used to suck out dust, and the adsorption device is connected to the dust removal box 41.

[0025] During the yarn conveying process, the yarn adjustment component 3 will adjust the distance between each strand of yarn to ensure the uniformity and stability of the yarn conveying. Then, the yarn enters the dust removal component 4 set at the top center of the main body 1. In the dust removal component 4, the yarn passes through the dust removal box 41 and comes into contact with the brushes 42 distributed up and down inside the dust removal box 41. The brushes 42 brush off the dust on the surface of the yarn. At the same time, the adsorption device is started to suck the brushed dust out of the dust removal box 41, completing the dust removal process of the yarn. The yarn after dust removal continues to be conveyed and passes through the gathering component 2. The gathering component 2 gathers multiple strands of scattered yarn into one strand, so that the yarn has a suitable shape to enter the subsequent process.

[0026] The dust removal assembly 4 also includes several air vents 411 located at the top and bottom of the dust removal box 41, and the air vents 411 are arranged along the length of the dust removal box 41. The suction device in the dust removal assembly 4 includes a negative pressure fan 43 that can circulate air in the dust removal box 41. The air inlet of the negative pressure fan 43 is connected to a first duct 431, which is also connected to the dust removal box 41. The air outlet of the negative pressure fan 43 is connected to a second duct 432. The dust removal assembly 4 also includes a collection box 44 located in the main body 1 for collecting dust, and one end of the second duct 432 extends into the collection box 44.

[0027] When yarn enters the dust box 41 of the dust removal assembly 4, the brush 42 contacts the yarn, brushing off dust. Simultaneously, the negative pressure blower 43 begins to operate, creating an air pressure differential between the top and bottom vents 411 of the dust box 41, promoting air flow within the dust box 41. The dust-laden air is drawn out by the negative pressure blower 43 through a first duct 431 and then transported through a second duct 432 to a collection box 44 located within the main body 1. The dust is then collected in the collection box 44.

[0028] The yarn gathering assembly 2 includes a support frame 21 fixed on the main body 1, and a yarn gathering ring 22 capable of gathering multiple yarns into one yarn is rotatably provided on the top of the support frame 21.

[0029] The yarn adjustment assembly 3 includes two sets of yarn guide assemblies 31 mounted on either side of the top of the main body 1. A yarn tensioning assembly 32 capable of adjusting the tension of the yarn is also provided on the yarn guide assembly 31 at the yarn input end. The yarn guide assembly 31 includes a connecting frame 311 fixed to the main body 1. A guide rod 3111 is provided near the bottom of the connecting frame 311. The yarn guide assembly 31 also includes several movable frames 312 slidably mounted on the guide rods 3111. The movable frames 312 are rotatably mounted with guide wheels 3121 for guiding the yarn. The yarn guide assembly 31 includes screws 313 rotatably mounted on the connecting frame 311 and used to drive the movement of each movable frame 312. The yarn guide assembly 31 also includes a rotary drive member 314 disposed on the exterior of the connecting frame 311 and used to drive the screws 313 to rotate.

[0030] If the distance between the yarn strands needs to be adjusted, the rotary drive member 314 is operated, which drives the screw 313 to rotate. The rotation of the screw 313 drives the movable frame 312, which is slidably mounted on the guide rod 3111, to move linearly along the guide rod 3111. The guide wheels 3121 on the movable frame 312 move accordingly, thereby changing the spacing between the guide wheels 3121, thereby achieving precise adjustment of the distance between the yarn strands. The coordinated operation of the two sets of yarn guide assemblies 31 ensures that the yarns maintain a neat and stable spacing throughout the entire conveying process, meeting the yarn arrangement requirements of subsequent processing.

[0031] The yarn tensioning assembly 32 includes an adjusting rod 322 rotatably set on the movable frame 312, and a wheel frame 3221 is set on the top of the adjusting rod 322, and a tensioning wheel 323 is rotatably set on the wheel frame 3221. The yarn tensioning assembly 32 also includes a telescopic driving member 321 rotatably set on the movable frame 312, and the output end of the telescopic driving member 321 is rotatably connected to the adjusting rod 322.

[0032] When the yarn tension needs to be adjusted, the telescopic drive 321 is activated. The telescopic drive 321 begins to telescope. Because its output end is rotatably connected to the adjustment rod 322, the telescopic movement of the telescopic drive 321 pushes or pulls the adjustment rod 322 about its rotation axis on the movable frame 312. The rotation of the adjustment rod 322 drives the wheel frame 3221 and the tensioning wheel 323 on top of it to move together. This, in turn, changes the relative position of the tensioning wheel 323 and the guide wheel 3121, thereby adjusting the yarn tension.

[0033] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
