Description

Technical Field

[0001] This utility model relates to the field of underwear knitting technology, specifically to a seamless underwear knitting device. Background Technology

[0002] Seamless underwear knitting equipment typically employs a circular knitting machine structure. Through the rotation of the cylinder and the up-and-down movement of the needles, along with components such as a needle selector and yarn guide, the yarn is knitted stitch by stitch into a tubular fabric. Utilizing a computer control system to precisely control the movement of each needle, it can achieve different knitting structures, patterns, and densities, thereby producing seamless underwear of various styles and specifications.

[0003] During operation, seamless underwear knitting equipment generates friction due to the continuous contact between the yarn and the knitting needles and yarn guides. This friction can easily cause the fibers on the yarn surface to be scratched and broken, resulting in a large amount of fuzz, especially during high-speed knitting, where the yarn may even break. Therefore, a seamless underwear knitting equipment has been proposed. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] This utility model provides a technical solution as follows: Figures 1 to 5 As shown, in this embodiment, a seamless underwear knitting device includes a U-shaped base 100, two fixing holes 102 are provided on the U-shaped base 100, a side plate 101 is fixedly connected to the side wall of the U-shaped base 100, and another fixing hole 102 is provided on the side plate 101. The yarn spool support rod 200 is fixedly installed at the upper end of the side plate 101 and is used to hold the yarn spool. The lubrication mechanism 300, mounted on the vertical plate of the U-shaped base 100, is used for lubricating the yarn with oil. It includes two housings 301 symmetrically arranged inside the U-shaped base 100. An adjustment mechanism is located on the side of the two housings 301 furthest from each other. Each housing 301 has an oil groove 302 at its closest point. An oil inlet 303 is located at the upper end of each oil groove 302. A guide wheel 306 is rotatably mounted at the opening of the oil groove 302. A guide recess is provided on the outer circumferential sidewall of the guide wheel 306. The guide wheel 306 extends out of the oil tank 302 on one side of the groove 309. The extension length of the guide wheel 306 is greater than the depth of the guide groove 309. The upper and lower ends of the guide wheel 306 are respectively fixedly connected to the rotating column 307. The upper and lower ends of the oil tank 302 are respectively provided with rotating grooves 305. The two rotating columns 307 are respectively rotated and engaged with the two rotating grooves 305. The inner walls of the opening of the oil tank 302 are respectively fixedly connected to the sealing element 304. The outer surface of the sealing element 304 is adapted to the outer surface of the guide wheel 306.

[0017] The adjustment mechanism includes two cylinders 500, which are symmetrically distributed on the opposite side of the two vertical plates of the U-shaped base 100. The telescopic rods of the cylinders 500 are fixedly connected to the side wall of the adjacent housing 301. The vertical plates of the U-shaped base 100 have through holes 105 for accommodating the telescopic rods of the cylinders 500. The inner diameter of the through holes 105 is larger than the outer diameter of the telescopic rods of the cylinders 500.

[0018] The PLC control system can control the synchronous extension and retraction of two cylinders 500, thereby controlling the distance between the two housings 301, and adjusting the clamping force of the two guide wheels 306 on the yarn. The clamping force needs to be adjusted according to the actual situation to avoid the guide wheels 306 not being able to rotate with the movement of the yarn due to insufficient clamping force.

[0019] The oil inlet 303 is fixedly connected to a connecting pipe 401, and the other end of the connecting pipe 401 is connected to a storage box 400. The bottom of the storage box 400 is fixedly connected to the U-shaped base 100 through a support plate 103, and the upper end of the storage box 400 is provided with an oil filling port 402.

[0020] The storage box 400 can store yarn lubricant for lubricating yarns, and the lubricant can be introduced into the oil tank 302 through the connecting pipe 401. The oil filling port 402 can be sealed by a piston.

[0021] Among them, a guide rod 104 is fixedly installed between the two vertical plates of the U-shaped base 100, and two guide sleeves 308 are slidably sleeved on the guide rod 104. The two guide sleeves 308 are respectively fixedly connected to the bottom of the housing 301.

[0022] The sliding engagement of the guide sleeve 308 and the guide rod 104 can guide the movement of the housing 301, ensuring that the two guide wheels 306 can be precisely aligned.

[0023] This utility model provides a seamless underwear knitting device, the specific working principle of which is as follows: The U-shaped base 100 and side plate 101 are fixed to the table of the seamless knitting machine with screws. The model of the seamless knitting machine can be referred to as GD-SJ18. The yarn spool is placed on the yarn spool support rod 200. The yarn is passed between the two guide wheels 306 and installed on the knitting mechanism of the seamless knitting machine. The two cylinders 500 are controlled to extend and retract synchronously by the PLC control system, so that the two guide wheels 306 clamp the yarn. When the sewing machine is working, the movement of the yarn will drive the guide wheels 306 to rotate. One side of the guide wheel 306 is located in the oil tank 302. When the guide wheel 306 rotates, the side of the guide wheel 306 with yarn lubricant will rotate out to contact the yarn, so that the outer wall of the yarn is coated with oil film, reducing the friction between the yarn and the knitting needle and yarn guide, reducing the yarn breakage rate during high-speed knitting, and improving the knitting properties of the yarn.

[0024] It should be noted that since only a thin oil film adheres to the guide wheel 306, the amount of yarn lubricant adhering to the yarn will be very small. It will usually be consumed during the contact process between the knitting needle and the yarn guide, and will not cause the fabric to be contaminated by the yarn lubricant.

[0025] It should also be noted that when an oil film is attached to the guide wheel 306, the friction between it and the yarn will be greatly reduced. This may cause the guide wheel 306 to be unable to rotate or to rotate too slowly when the yarn moves, thus preventing the guide wheel 306 from carrying out the yarn lubricant in the oil tank 302 (or carrying it out too slowly).

[0026] Assuming the above situation exists, it also means that the yarn lubricant attached to the contact point between the guide wheel 306 and the yarn is sufficient to lubricate the yarn. Even if the guide wheel 306 does not rotate or rotates too slowly, the purpose of lubricating the yarn has been achieved. When the yarn lubricant at the contact point between the guide wheel 306 and the yarn is insufficient, the friction between the guide wheel 306 and the yarn will naturally increase, and the rotation of the guide wheel 306 will naturally speed up.

[0027] The wiring diagrams of the PLC control system and cylinder 500 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the PLC control system and cylinder 500 will not be explained in detail.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
