In the embodiment of the application, the tension adjusting mechanism 13 keeps the tension of the weft yarn 4 consistent by adding tension to the weft yarn 4, improves the knitting quality and promotes the smooth running of the machine.
In this application embodiment, the leasing reed frame 2 is arranged in between creel 1 and shop's latitude dolly 3, and the leasing reed 21 that sets up in the leasing reed frame 2 plays the effect of fixed woof 4, avoids woof 4 to take off the problem that appears twining the knot when backing off.
In detail, referring to fig. 1 and 2, the tension adjusting mechanism 13 includes a mounting base 131 fixed on the creel 1, a mandrel 132 mounted on the mounting base 131, a tension disc 133 and a tension washer 134 movably sleeved on the mandrel 132 from bottom to top in sequence, and a guide roller 135 mounted on the mounting base 131 and located at one side of the mandrel 132; when a weft yarn 4 is introduced into the tension adjusting mechanism 13, the weft yarn 4 is led out after passing through the tension disc 133, around the spindle 132, around the guide roller 135.
In this application embodiment, the tension adjustment mechanism 13 is a disc type tension adjustment mechanism, when the weft yarn 4 is axially unwound, the absolute value of the tension of the weft yarn 4 is very small, such tension level can easily generate the problems of yarn breakage and the like, the tension of the weft yarn 4 can be properly increased by using the disc type tension adjustment mechanism, the product quality is improved, the principle of action is that the disc type tension adjustment mechanism utilizes friction braking on the yarn to enable the yarn to obtain necessary tension, and the disc type tension adjustment mechanism is simple in structure and convenient to adjust so as to adapt to the requirements of different yarn numbers.
In the present embodiment, the tension adjusting mechanism 13 adjusts the tension of the weft yarn 4 during the transportation by increasing the tension thereof by friction against the weft yarn 4. In this example, the tension adjusting mechanism 13 is a disc type tension adjusting mechanism. In addition, the disc type tension adjusting mechanism adopted in the embodiment has various forms, and can be divided into two types of accumulation method and double accumulation method according to different conditions of yarn passing through friction surfaces, and the two types of pressing can be divided into gasket pressing, spring pressing, air pressure pressing, electromagnetic pressing and the like according to positive pressure of yarn, and the embodiment adopts the gasket pressing mode.

In the embodiment of the application, aiming at the current situation that the rectangular sectional rotary creel is turned one by one manually, the embodiment realizes coexistence of a collective turning mode and an independent turning mode of the creel 11 through the unique structural design of the worm wheel 123 in the transmission mechanism 12, and maintains the flexibility of use while realizing automation and improving the working efficiency.
In the embodiment of the present application, when the creel 11 needs to be turned over collectively, the worm shaft 121 is driven to rotate in the arrow direction shown in fig. 1 from the motor, so as to form a transmission route of the motor→the worm shaft 121→the worm 122→the outer ring 1232 of the worm wheel 123→the stay 1233 of the worm wheel 123→the inner ring 1231 of the worm wheel 123→the rotation shaft 111 of the creel 11, wherein the inner ring 1231 of the worm wheel 123 rotates with the rotation shaft 111 of the creel 11 in the arrow direction shown in fig. 4.

The weft yarn 4 is firstly unwound from the creel 11 on the creel 1, unwinding tension is continuously changed due to the change of the unwinding radius of the bobbin in the unwinding process of the weft yarn 4, especially when the weft yarn 4 is unwound to the bottom of the bobbin, the tension of the weft yarn 4 is greatly different from that of the weft yarn at the beginning, the tension is uneven in the weft laying process, the phenomenon of accumulation of the weft yarn 4 on the cloth surface of the fabric is caused, and the cloth surface quality of the fabric is seriously influenced. The tension adjusting mechanism 13 is arranged on the creel 1 to compensate the problem of uneven tension change caused by unwinding, so that the fluctuation of the tension of the weft yarn 4 is effectively reduced. The weft thread 4 thus passes through the tension adjusting mechanism 13 after unwinding, i.e. first into the tension disc 133, then around the spindle 132, and then out of the tension disc 133, after rewinding around the guide roller 135, towards the leasing reed 21. The weft yarn 4 sequentially passes through the long eyelet 211 and the sealing reed eye 212 in the leasing reed 21 to realize leasing, then passes into the weft laying trolley 3, and is laid under the driving of the weft laying trolley 3.
In summary, the tension of the weft yarns in the full-width weft insertion warp knitting machine is adjusted through the cooperation of the creel, the tension adjusting mechanism and the leasing reed, so that the weaving process is smoother and smoother, and the weaving quality of the product is further improved integrally; in addition, the current situation that the rectangular sectional rotary bobbin creel is turned one by means of manpower is met, the collective turning mode and the independent turning mode of the bobbin creel coexist through the unique structural design of the worm wheel in the transmission mechanism, and the flexibility of use is maintained while automation and work efficiency improvement are achieved.
