Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn feeder technology, and in particular to a yarn feeder that facilitates yarn feeding. Background Technology
[0002] A yarn feeder is an important piece of equipment used in knitting machines. Its main function is to ensure that the yarn can be stably and continuously delivered to the knitting area during the knitting process, while maintaining constant tension of the yarn. However, traditional yarn feeders are inconvenient for threading yarn during use. Therefore, we need a yarn feeder that is easy to thread yarn.
[0003] During the patent application process, a search revealed a Chinese patent with patent number CN221343376U: A yarn feeder for easy yarn threading, comprising: a yarn feeding device, the yarn feeding device including a fixed bracket, a fixed frame fixedly connected to the fixed bracket, a yarn feeder body fixedly connected to the fixed frame, multiple yarn threading holes installed on the yarn feeder body, and a yarn threading component fixedly connected to the fixed frame; this device can help workers thread yarn quickly, and can also effectively reduce the friction during yarn feeding through the smooth rope. Furthermore, through the spacing adjustment component and the bending adjustment component, it can not only adjust the distance between the two first yarn feeding wheel assemblies, and not only keep the yarn threading rope assembly in a taut state, but also adjust the outward length of the yarn threading rope assembly, thus adapting it to different yarn feeders. After yarn threading is completed, the bending adjustment of the yarn threading rope assembly can also be performed, effectively preventing the yarn threading rope assembly from affecting the yarn feeding process.
[0004] The above solution adjusts the yarn tension through the spacing adjustment component during use. However, manually adjusting the yarn tension can cause the yarn tension to be too high and break, while too low tension may cause the yarn to loosen. This makes it difficult to control the yarn tension and thus affects the operation of the yarn feeder. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0026] Reference Figure 1-4 This utility model provides a yarn feeder that facilitates yarn threading, comprising: a yarn feeder body 1, a threading hole 2 on one side of the yarn feeder body 1, a fixing frame 3 fixedly connected to the lower part of the yarn feeder body 1, and a yarn threading component 4 on one side of the fixing frame 3.
[0027] The yarn threading assembly 4 includes a yarn threading frame 401 fixedly connected to one side of the fixed frame 3. A bidirectional lead screw 402 is rotatably connected to the inner wall of the yarn threading frame 401. Two sliding seats 403 are sleeved on the outer side of the bidirectional lead screw 402. A tension adjustment unit 5 is provided on the opposite side of the two sliding seats 403. A motor 404 is fixedly connected to one side of the yarn threading frame 401. A yarn feeding wheel 405 is fixedly connected to the output end of the motor 404. A yarn rope assembly 6 is provided on the outer side of the yarn feeding wheel 405.
[0028] The two tension adjustment units 5 include an adjustment column 501 fixedly connected to one side of the sliding seat 403. A slide rod 502 is slidably connected to the inner wall of the adjustment column 501. A spring assembly 503 is fixedly connected to one end of the slide rod 502 inside the adjustment column 501, and a mounting bracket 504 is fixedly connected to the other end of the slide rod 502 away from the spring assembly 503. A yarn feed wheel 505 is rotatably connected to the inner wall of the mounting bracket 504. The tension of the yarn can be adjusted by the tension adjustment units 5.
[0029] The slide rod 502 is located inside the adjusting column 501, and one end of it is T-shaped. The end of the spring assembly 503 away from the slide rod 502 is fixedly connected to the inner wall of the adjusting column 501.
[0030] The yarn assembly 6 includes a yarn-adhesive rope 601 and a connecting rope 602, with the connecting rope 602 fixed to both ends of the yarn-adhesive rope 601. The yarn assembly 6 can drive the yarn to perform the threading operation.
[0031] The yarn assembly 6 is fitted onto the outer walls of the first feed roller 405 and the two second feed rollers 505. The yarn assembly 6 allows the yarn to pass through the first feed roller 405 and the two second feed rollers 505.
[0032] A second motor 4011 is fixedly connected to the upper end of the yarn threading frame 401, and the output end of the second motor 4011 is fixedly connected to one end of the bidirectional lead screw 402. The second motor 4011 drives the bidirectional lead screw 402 to rotate.
[0033] A controller 7 is installed on one side of the yarn threading frame 401. The controller 7 is electrically connected to motor 404 and motor 4011. The controller 7 facilitates the operation and control of the device by the staff.
[0034] Working principle: When threading is required, start motor 404 until the part of the yarn-adhesive rope 601 in the yarn rope assembly 6 faces the yarn feeder body 1, then turn off motor 404. The operator then adheres the yarn to the yarn-adhesive rope 601, and then starts motor 404 again to drive the yarn feeder wheel 405 to rotate, so that the yarn-adhesive rope 601 drives the yarn through the threading hole 2, and then separates the yarn from the yarn-adhesive rope 601. When it is necessary to adjust the yarn tension, start motor 4011 to output the bidirectional lead screw 402 to rotate, thereby driving the two sliding seats 403 to move in opposite directions. The movement of the two sliding seats 403 drives the movement of the two yarn feeder wheels 505, thereby adjusting the yarn tension. In addition, if the tension is too high during the adjustment process, the sliding seats 403 will slide in the adjusting column 501, and the deformation force of the spring assembly 503 keeps the yarn tension constant, avoiding excessive stretching or loosening of the yarn.
[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
