Description

TECHNICAL FIELD

[0001] The present application relates to the field of warp knitting, in particular to a warp knitting machine with a JAKA creel. BACKGROUND

[0002] A warp knitting machine with a creel usually has yarn tension controllers installed between the creel and the main machine of the warp knitting machine to control the tension of the yarn after it is guided out of the creel and into the main machine of the warp knitting machine. The warp knitting machine also has a yarn guide structure installed between the creel, the disc head and the main machine of the warp knitting machine to prevent the yarn from intertwining after it is guided out of the creel or the disc head. A roller mechanism is provided below the creel. The yarn passes through the roller mechanism, and through the driving of a servo motor, the yarn changes from a free state to a yarn with the same tension. The existing warp knitting machine has the following problems in actual production process:

[0003] 1. The yarn tension control of the existing warp knitting machine is usually controlled by controlling the weight of the porcelain ring. This control method requires the staff to frequently adjust the number of porcelain rings to change the weight of the porcelain ring, thereby achieving control of the yarn tension. This results in an increase in the workload of the staff. Moreover, a set of warp knitting machine has more than 3300 tension controllers. It is often not practical to control the yarn tension by controlling the weight of the porcelain ring, which is not conducive to actual production.

[0004] 2. The yarn guide structure of the existing warp knitting machine is usually composed of a yarn guide needle and a yarn guide rod. With the passage of time, the yarn rubs against the yarn guide needle, which causes the yarn guide needle to wear and generate burrs, thereby causing the yarn to generate fluff, hang yarn, break yarn and other situations when the yarn is guided. This requires frequent replacement of the yarn guide needle, and the service life of the yarn guide needle is short.

[0005] 3. The roller mechanism of the existing technology only has one yarn guide roller, which cannot adjust the warp feed of the yarn. Moreover, when the yarn does not need to change the free state yarn into a yarn with the same tension through the roller mechanism during actual production, the yarn needs to be removed from the roller mechanism. The existing roller mechanism is relatively troublesome when installing and removing the yarn, which causes low production rate. SUMMARY

[0029] Beneficial effects:

[0030] 1. When the electronic tension controller of the JAKA warp knitting machine is used, the yarn enters the electronic tension controller from the first eyelet, rotates half a circle clockwise around the first yarn guide ring, and then rotates around the yarn retaining ring counterclockwise. After the yarn passes through the yarn retaining ring, it passes through the second yarn guide ring and is finally guided out through the second eyelet.

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described clearly and completely below in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are some of the embodiments of the application, rather than all the embodiments of the application.

[0052] Example 1, please refer to Figures 1 to 7The first embodiment of the application is a jacquard yarn frame warp knitting machine, which comprises a yarn frame 5 and a warp knitting machine main machine, the yarn frame 5 is installed above the warp knitting machine main machine, a plurality of electronic tension controllers for actively controlling the yarn tension are arranged on the side edges of the yarn frame 5,

[0053] In the embodiment, the electronic tension controller structure comprises a support 11, and a recess for accommodating components is arranged in the middle of the support 11.

[0054] A torque motor 12 is arranged on the rear side of the support 11, a first yarn guide ring 15 is arranged in the recess, and the first yarn guide ring 15 is connected with the rotating shaft of the torque motor 12.

[0055] A yarn holding ring 17 is arranged directly below the first yarn guide ring 15, and the yarn holding ring 17 is supported by a support plate mechanism, which is connected with the rotating shaft of the support 11.

[0056] An elastic support mechanism 111 is arranged between the support plate mechanism and the recess below the support plate mechanism, which provides the support plate mechanism with longitudinal elastic force, so that the yarn holding ring 17 on the support plate mechanism keeps in contact with the first yarn guide ring 15, thereby pressing the yarn to keep the yarn in contact with the first yarn guide ring 15 at all times; when the torque motor 12 drives the first yarn guide ring 15 to rotate, the yarn obtains the same tension as the torque motor 12, thereby controlling the tension of the yarn and achieving active control of the yarn tension. This active control method is different from the traditional passive control method of controlling the weight of the porcelain ring, and there is an essential difference between the two methods in changing the yarn tension, which eliminates the need for manual control and adjustment of the weight of the porcelain ring in the production process.

[0057] Specifically, the support plate mechanism comprises a first support plate 18 arranged on the front side of the yarn holding ring 17 and a second support plate 19 arranged on the rear side of the yarn holding ring 17, and the yarn holding ring 17 is arranged between the front and rear sides of the first support plate 18 and the second support plate 19, so that the yarn holding ring 17 is supported by the plates on both sides, and the structure is more stable.

[0058] In addition, the yarn holding ring 17 is connected with the left end rotating shaft of the first support plate 18, the yarn holding ring 17 is connected with the left end rotating shaft of the second support plate 19, the right end of the first support plate 18 is connected with the rotating shaft of the support 11 through a support plate rotating shaft 10, and the right end of the second support plate 19 is connected with the rotating shaft of the support 11 through a support plate rotating shaft 10.

[0059] In the embodiment, the elastic supporting mechanism 111 is composed of a spring 1111, an upper pin shaft 1112 arranged at the upper end of the spring 1111, and a lower pin shaft 1113 arranged between the spring 1111 and the support 11.

In order to realize the installation and fixation of the lower pin shaft 1113, the support 11 is provided with a lower pin shaft hole for installing the lower pin shaft 1113.

[0061] The left middle part of the support 11 is provided with a first porcelain eye 13 penetrating the groove, and the right middle part of the support 11 is provided with a second porcelain eye 14 penetrating the groove. The yarn enters the electronic tension controller from the first porcelain eye 13 and exits the electronic tension controller from the second porcelain eye 14.

[0062] Further, in order to facilitate the yarn leading out from the second porcelain eye 14, the first porcelain eye 13 and the second porcelain eye 14 are at the same horizontal height, and a second yarn guide ring 16 is further arranged in the groove. The second yarn guide ring 16 is at the same height as the first yarn guide ring 15, and the second yarn guide ring 16 is connected with the rotating shaft of the support 11.

[0063] Specifically, the working principle in the embodiment is as follows:

[0064] According to Figure 4 or Figure 5 the yarn 4 leading out from the creel enters the electronic tension controller from the first porcelain eye 13, and then reversely rotates around the first yarn guide ring 15 by half a circle and the yarn holding ring 17 in a clockwise direction. After the yarn 4 rotates around the yarn holding ring 17, it passes through the second yarn guide ring 16 and finally leads out from the second porcelain eye 14. Such a winding mode can make the yarn 4 rotate around the rotating shaft of the yarn holding ring 17, and through the elastic effect of the spring 1111, the yarn holding ring 7 and the first yarn guide ring 15 keep in contact, thereby pressing the yarn 4 to keep in contact with the first yarn guide ring 15. When the first yarn guide ring 15 rotates under the driving of the torque motor 12, the yarn 4 obtains the tension of the torque motor, thereby controlling the tension of the yarn and realizing the active control of the yarn tension.
