Abstract

The utility model discloses an improved yarn delivery wheel, comprising a cylindrical thread winding surface (1) and an end cover (3) integrated with the thread winding surface (1), wherein, a plurality of thread cutting grooves (2) are arranged on the thread winding surface (1); 2-12 wind wheels are arranged above the end cover (3). In the high speed rotating process of the wind wheels along with the yarn delivery wheel, enduring whirlwind flow can be produced, which can blow the broken yarns off the yarn delivery wheel shaft, preventing the broken yarns winding on the yarn delivery wheel shaft, saving yarn removing time and improving production efficiency; and can also blow away the batt suspending inside the device so as to prevent the batt entering into bearings, which not only saves batt clearing time, but also improves the life-span of the bearings. On the other hand, the whirlwind flow produced by the wind wheels plays a role in cooling, so as to prolong the life-span of the bearings effectively.

Description

A kind of improved defeated yarn wheel

Technical field the utility model relates to a kind of for knitting machine stores up yarn, send the defeated yarn of yarn to take turns, and is called yarn feeding wheel or yarn storage wheel again.

Background technology is well-known, and defeated yarn wheel is to guarantee that yarn at the uniform velocity, balancedly feeds the key device of knitting machine.Existing defeated yarn wheel is general to be adopted the coral bar or claims large carrying food-basket formula structure, such as Chinese utility model patent CN2292817 " magnetic tension force storage yarn yarn-feeding device ", one end cap is arranged at the yarn storage wheel top in this device, and end cap and wheel shaft fixedly become one, and the coiling surface of yarn storage wheel is coral hurdle shape.

The defective of this class yarn-feeding device is, the broken string of Chan Shenging is wrapped on the wheel shaft easily in the course of the work, and the titbit that constantly produces is easy to enter into the bearing of wheel shaft.In this case, have to shut down cleaning, influenced the normal operation of operation, reduced production efficiency.On the other hand, continuous high speed rotates because defeated yarn is taken turns in the course of the work, and the spin friction of bearing produces certain heat, and the bearing length time is under the hot environment, and be affected service life.

Utility model content the purpose of this utility model is the deficiency that overcomes above-mentioned existing procucts, and provides a kind of defeated yarn wheel with self-cleaning function, promptly a kind of improved defeated yarn wheel.

The technical solution of the utility model is as follows:

A kind of improved defeated yarn wheel constitutes by cylindrical coiling face with the end cap of this coiling face one, offers several sanction wire casings on coiling face, it is characterized in that: be provided with 2--12 fan blade above end cap.

The quantity of described fan blade is good with 3--6.

Described sanction wire casing can be a groove, also can be vee gutter.

The utility model is compared with existing like product and is had following characteristics, and (1), fan blade can produce lasting tornado flow with in the defeated yarn wheel high speed rotary course, defeated yarn wheel shaft can blow off disconnected yarn, avoid broken string to be wrapped on the defeated yarn wheel shaft, saved clearing time, improved production efficiency.(2), the tornado flow that produces of fan blade can blow away the titbit that is suspended in device inside, enters in the bearing to avoid these titbit, not only saved the time of removing titbit, and service life of having improved bearing.(3), the tornado flow that produces of fan blade played cooling effect to bearing, with the service life of effective prolongation bearing.(4), realized the continuous operate as normal of knitting equipment, cloth cover is smooth, even, float is effectively controlled.

Description of drawings Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the vertical view of Fig. 1.

The specific embodiment such as Fig. 1, shown in Figure 3, the utility model comprise cylindrical coiling face 1 and constitute with the end cap 3 of this coiling face 1 one, offer several and cut out wire casing 2 on coiling face 1, are provided with 6 fan blades 4 above end cap 3.Fan blade 4 is one with end cap 3, processes by metal casting or plastics injection system.

Described sanction wire casing 2 can be a groove, and in this case, defeated yarn wheel coiling face 1 promptly is a coral hurdle shape.Cutting out wire casing 2 also can be vee gutter, as shown in Figure 2.The effect of cutting out wire casing 2 is when thread-changing or replacing Thread-feeding device, is convenient to cut off yarn.

The utility model and wheel shaft fix, and are installed on the yarn-feeding device in the lump.
