Description

a creel

technical field

The invention belongs to the field of textile machinery, in particular to a creel.

Background technique

It is very necessary to control the tension of the yarn in the weaving process of the textile industry. The yarn is drawn and unwound from the yarn wheel and arranged side by side to become a warp. The tension control during this period directly affects the flatness and performance of the cloth surface. There is no suitable tension for each strand of yarn, and it is very easy to cause adhesion, interference, entanglement and the like. In addition, in order to obtain high-quality textile products, the tension of each yarn bundle should also be kept stable and consistent. If the tension is too high, the yarn will fluff and break, and if the tension is too small, the control effect will not be obvious. Most of the current textile machinery involves tension control devices, most of which use fixed tensioners, which cannot be adjusted once the tension is given, and cannot adapt to the needs of process changes, let alone satisfy the consistent tension between multiple yarn bundles; The structure of the tensioner with the adjustment function is more complicated, it is inconvenient to disassemble and maintain, and the input cost is large. Therefore, how to avoid the adhesion, interference, and entanglement of each bundle of yarns during the preparation of textile products, and how to maintain uniform and consistent tension of each bundle of yarns is a problem that those skilled in the art need to solve at present.

Contents of the invention

The problem to be solved by the present invention is to provide a creel with simple structure, convenient operation and reasonable yarn guide control, which can realize the tension adjustment of single yarn bundle and the synchronous adjustment of tension of multiple yarn bundles, and maintain the tension of single yarn bundle. Stability and consistency of multi-strand yarn tension greatly improve the appearance quality and performance of the product.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a creel, including a bracket, several groups of yarn wheels and a brake assembly arranged on the bracket, characterized in that: the brake assembly includes a brake wheel, a brake lever and a brake The brake wheel is mounted on one end of the yarn wheel and coaxially linked with the yarn wheel. The brake lever is movably mounted on the bracket and driven by a power device on one side of the bracket. One end of the brake belt is fixed on the bracket. The other end of the brake band is connected to the brake lever after bypassing the outer rim of the brake wheel, and the brake lever slides reciprocally under the drive of the power device, thereby driving the brake band to hold or loosen the brake wheel.

When the brake belt tightly hugs the brake wheel, it generates a damping torque on the brake wheel, while the loom generates a traction torque on the yarn wheel when the traction yarn is unwound from the yarn wheel. Under the joint action of torque, tension is generated and straightened; but as the number of yarn coils on the yarn wheel decreases, the traction torque decreases accordingly. At this time, the degree of tightness between the brake band and the brake wheel changes under the traction of the brake lever The damping torque is adjusted when the yarn wheel rotates, so that the yarn bundle always maintains a uniform and stable tension.

Further, the other end of the brake band is connected to the brake lever through an elastic adjustment device. The individual control of the tension of the yarn bundle on a single yarn wheel is realized through the elastic adjustment device, so as to keep the tension of the single yarn bundle stable.

Further, the elastic adjusting device includes an connecting pin fixed on the brake lever and an adjusting screw threaded on the connecting pin. One end of the adjusting screw is covered with a wing nut, and the other end of the adjusting screw is connected to the brake band through a tension spring. Through the adjustment of the wing nut, the tension force of the extension spring on the brake band is changed, thereby changing the tightness of the brake band to the outer rim of the brake wheel, thereby realizing the tension control of the single yarn bundle.

Further, the bracket is provided with a fixing pin for connecting the brake band.

Further, the yarn wheels installed horizontally on the bracket are in one group, each group of yarn wheels corresponds to a brake lever, and the corresponding parts of the bracket are provided with connecting blocks for wearing the brake lever. The synchronous adjustment of the tension of the multi-strand yarns on a group of yarn wheels is realized through the brake lever, and the consistency of the tension of the multi-strand yarns in a group of yarn wheels is maintained.

Further, several sets of guide wire rods are provided on the bracket respectively corresponding to each group of yarn wheels, and each set of wire guide rods includes a multi-hole guide wire rod and a single-hole guide wire rod. Through the yarn guiding function of the guide wire rod, it can prevent the multi-ply yarn from sticking, interfering and twisting in the early stage of unwinding.

Further, the power device includes a cylinder and an air source connected to the cylinder, and the driving end of the cylinder is connected to one end of the brake lever.

Further, the support is composed of two unit creels, and each unit creel is equipped with the same number of yarn wheel sets, and the two adjacent sets of yarn wheels between the two unit creels correspond to two brakes. The rods are driven synchronously by the same cylinder through the transmission block. The bracket with the above structure not only saves space, but also improves the energy utilization rate of the power device.

Further, each unit creel is provided with 4 to 7 sets of yarn wheels, and the number of yarn wheels in each set of yarn wheels is 10 to 15.

Further, the yarn wheel is a one-way rotating wheel, that is, it can only rotate in the unwinding direction of the yarn bundle, so as to improve the precision of tension control.
