Description

Technical Field

[0001] This utility model relates to the field of yarn feeding nozzle technology, specifically a yarn feeding nozzle device for a weft knitting circular knitting machine. Background Technology

[0002] The yarn feeder is an indispensable component in a circular knitting machine. Its main function is to guide the yarn and position it appropriately on the knitting needles. However, due to differences in fabric structure and type, the yarn input angle and tension must also be adjusted accordingly. By adjusting the position of the yarn feeder, the yarn can be guided to the optimal position, thereby ensuring the quality of the fabric.

[0003] Currently, the yarn feeders of existing circular knitting machines are bolted to the yarn feeder frame, resulting in a fixed position for the yarn feeder and the corresponding fixed position of the yarn feeder holes. However, in the actual knitting process of a circular knitting machine, different processes have different requirements. Due to the different processes, the fixed yarn feeder holes in the corresponding yarn feeder cannot be adjusted according to the process requirements, which has certain limitations. Therefore, a yarn feeder device for weft knitting circular knitting machines is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a yarn feeding device for a weft knitting circular knitting machine, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a yarn feeding nozzle device for a weft knitting circular knitting machine, including a mounting base, an adjustment mechanism on the mounting base, a sand feeding nozzle body on the adjustment mechanism, a sand feeding hole on the sand feeding nozzle body, and a second ceramic eye fixedly installed inside the sand feeding hole; The adjusting mechanism includes a connecting rod and a connecting plate. The connecting plate is fixedly installed on the connecting rod. A push block is fixedly installed on the connecting rod. A spring is provided on the connecting rod. A positioning post is fixedly installed on the connecting plate. A positioning hole is provided on the sand feeder body. The positioning post is inserted into the positioning hole. A limit block is fixedly installed on the push block.

[0006] Preferably, a bearing is fixedly installed on the mounting base, and the feeding nozzle body is fixedly installed on the outer wall of the outer ring of the bearing. The mounting base is provided with a fastening hole. The bearing allows the feeding nozzle body to rotate easily, making it convenient to adjust the angle of the feeding nozzle body.

[0007] Preferably, the mounting base has a limiting groove, the limiting block is slidably connected inside the limiting groove, one end of the spring abuts against the button, and the other end of the spring abuts against the mounting base. The limiting groove and the limiting block can limit the button and prevent the button from detaching from the mounting base.

[0008] Preferably, the feeding nozzle body is provided with a tensioning mechanism, which includes a fixing frame. The fixing frame is fixedly installed on the feeding nozzle body. The tensioning mechanism allows for easy adjustment of the tension during yarn feeding, preventing the yarn from breaking due to excessive tension.

[0009] Preferably, the fixed frame is threadedly connected to a threaded rod, the upper end of the threaded rod is rotatably connected to an adjusting seat via a bearing, and the lower end of the threaded rod is fixedly installed with a throttle handle, which allows for easy installation of a rotating threaded rod.

[0010] Preferably, the adjusting seat has a mounting hole, and a first ceramic eye is fixedly installed inside the mounting hole. The first ceramic eye can protect the yarn.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0012] 1. The yarn feeding nozzle device of this weft knitting circular knitting machine allows the user to adjust the position and angle of the yarn feeding hole by pressing the button with their finger. This causes the button to move through the connecting rod and push the connecting plate, disengaging the positioning pin on the connecting plate from the positioning hole. At this point, the yarn feeding nozzle body loses its positioning and can rotate, thereby adjusting the position and angle of the yarn feeding hole. After the position adjustment is completed, the button is released, allowing it to move under the force of the spring, thus inserting the positioning pin into another positioning hole and fixing the position of the yarn feeding nozzle body. This facilitates the user's quick adjustment of the position and angle of the yarn feeding hole.

[0013] 2. The yarn feeding nozzle device of this weft knitting circular knitting machine allows the user to rotate the handle to drive the threaded rod to rotate when the yarn tension needs to be adjusted. This causes the threaded rod to move the adjusting seat downward, thereby adjusting the distance between the first ceramic eye and the second ceramic eye, thus adjusting the yarn tension and preventing the yarn from breaking due to excessive tension. This further improves the practicality of the yarn feeding nozzle device. Attached Figure Description

[0020] Please see Figure 1-5One embodiment of this utility model is: a yarn feeding nozzle device for a weft knitting circular knitting machine, including a mounting base 1, an adjustment mechanism 2 is provided on the mounting base 1, a sand feeding nozzle body 4 is provided on the adjustment mechanism 2, a sand feeding hole 6 is provided on the sand feeding hole 6, and a second ceramic eye 7 is fixedly installed inside the sand feeding hole 6. The adjusting mechanism 2 includes a connecting rod 201 and a connecting plate 202. The connecting plate 202 is fixedly installed on the connecting rod 201. A button 205 is fixedly installed on the connecting rod 201. A spring 206 is provided on the connecting rod 201. A positioning post 203 is fixedly installed on the connecting plate 202. A positioning hole 204 is provided on the sand feeding nozzle body 4. The positioning post 203 is inserted into the positioning hole 204. A limit block 207 is fixedly installed on the button 205. When it is necessary to adjust the angle of the position of the sand feeding hole 6, the user presses the button 205 with his / her finger to adjust the angle of the button. 205 pushes the connecting plate 202 to move via the connecting rod 201, causing the positioning post 203 on the connecting plate 202 to disengage from the interior of the positioning hole 204. At this time, the feeding nozzle body 4 loses its positioning and can rotate, thereby achieving the purpose of adjusting the position angle of the feeding hole 6. After the position adjustment is completed, the button 205 is released, causing the button 205 to move under the force of the spring 206, thereby inserting its positioning post 203 into another positioning hole 204, thus fixing the position of the feeding nozzle body 4, making it convenient for the user to quickly adjust the position angle of the feeding hole 6.

[0021] A bearing 209 is fixedly installed on the mounting base 1, and the feeding nozzle body 4 is fixedly installed on the outer wall of the outer ring of the bearing 209. The mounting base 1 is provided with a fastening hole 5. The bearing 209 allows the feeding nozzle body 4 to rotate easily, making it convenient to adjust the angle of the feeding nozzle body 4.

[0022] The mounting base 1 has a limiting groove 208, and a limiting block 207 is slidably connected inside the limiting groove 208. One end of the spring 206 abuts against the button 205, and the other end of the spring 206 abuts against the mounting base 1. The limiting groove 208 and the limiting block 207 can limit the button 205 and prevent the button 205 from falling off the mounting base 1.

[0023] Working principle: When the angle of the feeding hole 6 needs to be adjusted, the user presses the button 205 with their finger, causing the button 205 to push the connecting plate 202 to move through the connecting rod 201. This causes the positioning post 203 on the connecting plate 202 to disengage from the positioning hole 204. At this time, the feeding nozzle body 4 loses its positioning and can rotate, thereby achieving the purpose of adjusting the angle of the feeding hole 6. After the position adjustment is completed, the button 205 is released, causing the button 205 to move under the force of the spring 206, thereby causing its positioning post 203 to be inserted into another positioning hole 204, thus fixing the position of the feeding nozzle body 4, which makes it easy for the user to quickly adjust the angle of the feeding hole 6.

[0024] Please see Figure 1-5 Based on the above embodiments, in another embodiment of the present invention, a tensioning mechanism 3 is provided on the feeder body 4. The tensioning mechanism 3 includes a fixing frame 301, which is fixedly installed on the feeder body 4. The tensioning mechanism 3 can be used to conveniently adjust the tightness of the yarn during the yarn feeding process, and avoid the problem of the yarn breaking due to excessive tension.

[0025] A threaded rod 302 is threadedly connected to the fixed bracket 301. The upper end of the threaded rod 302 is rotatably connected to the adjusting seat 303 via a bearing. A throttle 306 is fixedly installed at the lower end of the threaded rod 302. The throttle 306 allows for easy rotation of the threaded rod 302.

[0026] The adjusting seat 303 has a mounting hole 304, and a first ceramic eye 305 is fixedly installed inside the mounting hole 304. The first ceramic eye 305 can protect the yarn.

[0027] Working principle: When the tension of the yarn needs to be adjusted, the user can turn the handle 306 to drive the threaded rod 302 to rotate, so that the threaded rod 302 drives the adjusting seat 303 to move downward, thereby adjusting the distance between the first ceramic eye 305 and the second ceramic eye 7, realizing the adjustment of the yarn tension, avoiding the problem of the yarn breaking due to excessive tension, and further improving the practicality of the feeding nozzle device.

[0028] This utility model provides a yarn feeding nozzle device for a weft knitting circular knitting machine. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
