Description

Technical Field

[0001] The utility model relates to the technical field of knitting machinery, in particular to a yarn guiding device for seamless underwear machines that prevents yarn fluff from clogging the yarn nozzles. Background Art

[0002] ‌A seamless underwear machine performs operations such as interspersing, kneading, and cutting the yarn of the fabric with an elastic band through a high-speed rotating needle to achieve fast and efficient production of underwear. This equipment is mainly used for producing seamless knitted products and is suitable for making categories such as underwear, swimsuits, and sportswear.‌

[0003] In the existing seamless underwear machines, once a blockage occurs, the transportation of the yarn will be forced to interrupt, which requires operators to spend time cleaning the blocked fluff and readjusting the yarn guiding device, making the production process unable to proceed continuously. If the fluff mixes into the underwear fabric after the blockage, it will cause defects on the surface of the product. Summary of the Utility Model

[0004] The utility model discloses a yarn guiding device for seamless underwear machines that prevents yarn fluff from clogging the yarn nozzles, aiming to solve the technical problems that in the existing seamless underwear machines, if a blockage occurs, the yarn transportation is interrupted, operators need to clean the fluff and adjust the yarn guiding device, resulting in production interruption, and after the blockage, the fluff mixes into the fabric, causing defects on the surface of the product.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A yarn guiding device for seamless underwear machines that prevents yarn fluff from clogging the yarn nozzles includes a yarn guiding controller. Above the yarn guiding controller is arranged a fluff dust suction assembly. The fluff dust suction assembly includes a limit ring frame. Inside the limit ring frame is movably connected a dust collection ring bin. And at the bottom of the dust collection ring bin are fixedly connected a plurality of dust suction heads. At the top of the dust collection ring bin is fixedly connected a dust suction pipe. The bottom end of the dust suction pipe is fixedly connected to an air pump. Above the dust collection ring bin are arranged symmetrically connecting plates. And at the bottom end of the connecting plate close to the dust suction pipe is fixedly connected a telescopic electric rod. The bottom end of the telescopic electric rod is fixedly connected to the top end of the dust collection ring bin. At the bottom end of the connecting plate far from the dust suction pipe is fixedly connected a compression spring. And the bottom end of the compression spring is fixedly connected to the top end of the dust collection ring bin.

[0006] By setting a yarn guiding controller and a lint suction assembly, when the yarn guiding device of the seamless underwear machine is running, the yarn enters the yarn guiding controller, and the lint suction assembly starts to work. The air pump is started, and suction is generated through the suction pipeline. The dust collection ring bin is movable within the limit ring frame. When the position needs to be adjusted, the telescopic electric rod extends or retracts, driving the dust collection ring bin to move closer to or away from one side of the suction pipeline. At the same time, the compression spring on the other side cooperates with the telescopic movement to keep the dust collection ring bin stable and capable of flexibly adjusting the height. The suction head approaches the yarn, sucking the lint on the yarn into the dust collection ring bin, completing the suction cleaning of the yarn lint. During the process, after cleaning the lint, the appearance of the knitted seamless underwear is smoother and more delicate, which can improve the quality and grade of the product, and can be supplied to the knitting area more efficiently, avoiding problems such as yarn blockage and entanglement caused by lint, enabling the knitting process to proceed continuously and stably, thereby improving the efficiency of the entire seamless underwear production.

[0007] In a preferred solution, a plurality of equally spaced perforations are formed on the limit ring frame. Vertical frames are fixedly connected inside the perforations, and the bottom ends of the vertical frames are fixedly connected to the top end of the yarn guiding controller. An operating platform is fixedly connected to the top end of the yarn guiding controller, and the operating platform is located directly below the lint suction assembly. The top end of the vertical frame is fixedly connected with an inner ring. A plurality of yarn rods are fixedly connected to the top end of the inner ring. The top ends of the yarn rods are fixedly connected with outer rings. Yarn bobbins are movably connected to the outer sides of the yarn rods. A plurality of fixing frames are fixedly connected to the top end of the inner ring, and electronic yarn guides are fixedly connected to the top ends of the fixing frames. A plurality of yarn guiding plates are fixedly connected to the inner sides of the vertical frames. The yarn guiding plates are located between the lint suction assembly and the operating platform. A plurality of yarn holes are formed on the yarn guiding plates, and lint cleaning assemblies are arranged on the yarn holes. The bottom end of the air pump is fixedly connected with a mounting member, and the outer side of the mounting member is fixedly connected to one side of the yarn guiding controller.

[0008] In a preferred solution, the lint cleaning assembly includes telescopic rods. A plurality of sliding groove holes are formed around the yarn holes on the yarn guiding plate. The telescopic rods are fixedly connected between the inner walls of the sliding groove holes, and a plurality of buffer springs are fixedly connected to the inner walls of the sliding groove holes. The buffer springs are all located outside the telescopic rods. A sliding seat is fixedly connected between the front sides of the plurality of telescopic rods and the buffer springs. A deshredding knife is fixedly connected above each sliding seat, and the plurality of deshredding knives form a ring. A ring-shaped frame is fixedly connected to the bottom end of the yarn guiding plate, and the ring-shaped frame is located below the yarn hole. Symmetrical support frames are fixedly connected to the inner wall of the ring-shaped frame. Ring-shaped rods are fixedly connected inside the support frames, and a plurality of rolling balls are movably connected to the outer sides of the ring-shaped rods. The outer sides of the rolling balls are in contact with the outer side of the yarn.

[0009] By setting up a lint cleaning component, when the yarn passes through the yarn holes on the yarn guide plate, first of all, when the yarn moves in the yarn holes, it will have a relative movement with the de-linting knives that form a ring. When encountering lint attached to the yarn, the de-linting knives will scrape it off. If the position of the yarn is offset or it is pulled by a certain external force, the telescopic rod and the buffer spring will play a role. The buffer spring uses its elasticity to buffer the impact force caused by the yarn offset, avoiding damage to the yarn by the de-linting knives, while the telescopic rod restricts the movement of the sliding seat within a certain range, ensuring that the de-linting knives always stay in a position where they can effectively clean the lint. Even if the yarn shakes slightly, it can ensure the continuous progress of the lint cleaning work. At the same time, due to the passing of the yarn, the rolling balls in contact with the outer side of the yarn will roll as the yarn moves. The annular rod supports the rolling balls, enabling them to rotate flexibly. This not only reduces the frictional resistance between the yarn and the yarn holes, ensuring the smooth passage of the yarn, but also keeps the yarn in a stable position to a certain extent during the traveling process, thereby achieving the effective cleaning of the lint on the outer side of the yarn, improving the quality of the yarn, ensuring the smooth progress of the subsequent knitting work of the seamless underwear machine, and reducing product defects and equipment failures caused by lint.

[0010] As can be seen from the above, a yarn guiding device for a seamless underwear machine that prevents yarn lint from clogging the yarn nozzle provided by the present utility model has the technical effects that after cleaning the lint, the appearance of the knitted seamless underwear is smoother and more delicate, which can improve the quality and grade of the product, can be more efficiently supplied to the knitting area, avoids the problems of yarn clogging and entanglement caused by lint, enables the knitting process to proceed continuously and stably, and thus improves the efficiency of the entire seamless underwear production.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Refer to Figure 1 , Figure 2 and Figure 3, in a preferred embodiment, a plurality of equally spaced perforations are formed in the limit ring frame 901. The interiors of the perforations are each connected to the vertical frame 2 by bolts, and the bottom end of the vertical frame 2 is connected to the top end of the yarn guiding controller 1 by bolts. The top end of the yarn guiding controller 1 is connected to the operating table 3 by bolts. The operating table 3 is located directly below the lint suction assembly 9. The top end of the vertical frame 2 is connected to the built-in ring 4 by bolts. The top end of the built-in ring 4 is connected to a plurality of yarn rods 5 by bolts. The top ends of the yarn rods 5 are each connected to the external circular frame 8 by bolts. The outer sides of the yarn rods 5 are each rotatably connected to a yarn bobbin 7. The top end of the built-in ring 4 is connected to a plurality of fixing frames 12 by bolts. The top ends of the fixing frames 12 are each connected to an electronic yarn guide 6 by bolts. The inner sides of the plurality of vertical frames 2 are each connected to a yarn guiding plate 11 by bolts. The yarn guiding plate 11 is located between the lint suction assembly 9 and the operating table 3. A plurality of yarn holes are formed in the yarn guiding plate 11, and lint cleaning assemblies 13 are each disposed on the yarn holes. The bottom end of the air pump 908 is connected to the mounting member 10 by bolts. The outer side of the mounting member 10 is connected to one side of the yarn guiding controller 1 by bolts.

[0021] Referring to Figure 2 and Figure 5 , in a preferred embodiment, the lint cleaning assembly 13 includes a telescopic rod 1301. A plurality of sliding groove holes are formed around the yarn holes on the yarn guiding plate 11. The telescopic rod 1301 is connected between the inner walls of the sliding groove holes by bolts. A plurality of buffer springs 1302 are each connected to the inner walls of the sliding groove holes by bolts. The buffer springs 1302 are each located outside the telescopic rod 1301. A sliding seat 1303 is connected between the front sides of the plurality of telescopic rods 1301 and the buffer springs 1302 by bolts. A deshredding knife 1304 is connected to the upper side of each sliding seat 1303 by bolts. The plurality of deshredding knives 1304 are arranged in a ring. The bottom end of the yarn guiding plate 11 is connected to an annular frame 1305 by bolts. The annular frame 1305 is located below the yarn holes. Symmetric support frames 1306 are connected to the inner wall of the annular frame 1305 by bolts. An annular rod 1307 is connected to the inside of each support frame 1306 by bolts. A plurality of rolling balls 1308 are each rotatably connected to the outer side of the annular rod 1307. The outer sides of the rolling balls 1308 are in contact with the outer side of the yarn.

[0022] Working principle: First, the yarn bobbin 7 is sleeved on the yarn rod 5. The yarn rod 5 prevents the yarn bobbin 7 from slipping through the external circular frame 8. After the yarn is led out from the yarn bobbin 7, it undergoes preliminary tension adjustment and guidance through the electronic yarn guide 6. The electronic yarn guide 6 can control the conveying speed and tension of the yarn according to preset parameters to ensure that the yarn can stably enter the subsequent yarn guiding link. The yarn passing through the electronic yarn guide 6 is guided to the yarn hole on the yarn guiding plate 11. During the process of the yarn passing through the yarn hole, due to the presence of the lint cleaning component 13 on the yarn guiding plate 11, the preparation for lint cleaning begins. At this time, structures such as the telescopic rod 1301 in the lint cleaning component 13 remain relatively stable in the chute hole, the buffer spring 1302 provides a certain elastic support, and the deshredding knife 1304 is in a waiting working state. At the same time, the ball 1308 in the annular frame 1305 contacts the outer side of the yarn, playing a role in assisting the yarn to pass through the yarn hole smoothly, reducing the friction and jamming of the yarn. When the yarn exits from the yarn guiding plate 11, it enters the operation table 3 area below the lint suction component 9. At this time, the air pump 908 starts, generating suction in the suction pipeline 907. Due to the suction force, the suction head 903 at the bottom of the dust collection ring bin 902 begins to adsorb the lint around the yarn. The position of the dust collection ring bin 902 in the limit ring frame 901 can be adjusted through the cooperation of the telescopic electric rod 906 and the compression spring 904. When the telescopic electric rod 906 expands or contracts, one side of the dust collection ring bin 902 rises or falls, and the compression spring 904 on the other side is correspondingly compressed or extended, enabling the dust collection ring bin 902 to flexibly approach or move away from the yarn to achieve the best dust suction effect. The lint is sucked into the dust collection ring bin 902 by the suction head 903 and then collected through the suction pipeline 907, thereby realizing the cleaning of the yarn lint. Finally, the yarn enters the interior of the operation table 3 for the yarn guiding and knitting of seamless underwear.

[0023] As described above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present utility model and its inventive concept should be covered within the protection scope of the present utility model.
