Description

Technical Field

[0001] The invention relates to the technical field of yarn processing machines, in particular to a yarn guiding and threading mechanism for a textile yarn processing machine and a use method thereof. Background Art

[0002] In the development of modern textile industry, there are many forms of shuttleless looms, including rapier looms, projectile looms, air jet looms, water jet looms, multi-phase looms, magnetic weft insertion looms, etc. Compared with shuttle looms, the fabrics produced by shuttleless looms have incomparable advantages in terms of output, quality, variety, etc., and have replaced shuttle looms in most weaving fields. This pace has further accelerated and has expanded from the textile industry in developed countries to developing countries. From the perspective of the international technical development of shuttleless looms and the needs of the textile industry, air jet looms have made rapid progress in high speed, wide width, and serialization. In addition to being widely used in the cotton weaving industry with large quantities and wide applications, they are increasingly widely used in yarn-dyed, jacquard and other fabrics. Rapier looms have advantages in variety adaptability, fabric color and variety changes, and a wider range of weaving applications. These two types of looms have become the two types of looms with the largest number of applications in the textile industry.

[0003] Traditionally, looms that use yarn for weaving can be divided into two major categories: weaving and knitting. Weaving looms include the original shuttle looms and the new shuttleless looms. The shuttleless looms mainly include rapier looms, air jet looms, water jet looms and projectile looms. Knitting machines are divided into two major categories: warp knitting and weft knitting, which have many subcategories.

[0004] In the knitting category, the development of Chinese weaving machinery products is uneven, among which circular knitting machines and warp knitting machines develop rapidly, flat knitting machines and hosiery machines develop relatively slowly, and crochet machines develop rapidly. The basic products of domestic circular knitting machines with large volume and wide application are relatively complete, including single-sided and double-sided circular knitting machines, rib machines and artificial fur machines. Among the single-sided circular knitting machines, there are four-needle tracks, terry, weft insertion, and multi-functional single-sided machines.

[0005] It varies depending on the type of "knitting machine". The yarn guide on the latch needle circular knitting machine is also called a steel shuttle. Its function is to accurately pad the yarn onto the knitting needle through the yarn guide hole on it. The second is to strictly control the movement of the needle tongue to prevent the needle tongue, which is in a free state after the loop is withdrawn, from closing the needle mouth to ensure the smooth knitting. The yarn guide on the "flat knitting machine" moves back and forth along the "needle bed" with the triangle seat to pad the yarn onto the corresponding knitting needle. The yarn guide on the circular sock machine enters (descends) or exits (lifts up) according to the knitting needs. The yarn guide needle of the warp knitting machine swings between the needles or moves horizontally in front of or behind the needles according to the knitting needs to accurately pad the yarn onto the knitting needles.

[0006] For example, the application number 201810097112.1 discloses a yarn guide device for a knitting machine, including a base plate, a yarn guide pulley, a single yarn detection ring, a short circuit sensor, an upper lead and a lower lead, a metal contact pin is provided on the inner side of the outer wall, a metal movable push plate is provided between the inner wall and the outer wall, a single yarn channel that only allows a single yarn to pass through is formed between the metal movable push plate and the inner wall, the adjustment shaft is rotatably mounted on the base plate, and the yarn guide pulley, the single yarn detection ring, the first yarn threading ring, and the second yarn threading ring cooperate with each other in sequence to guide the yarn into the knitting mechanism. The present invention cooperates with the single yarn detection ring, the metal movable push plate, the metal contact pin, and the short circuit sensor. If the yarn is knotted or twisted into a ball, an alarm is issued in time, and the machine is automatically stopped to prevent the knotted and twisted yarn from entering the textile parts; the short circuit sensor cooperates with the alarm signal light and the alarm to accurately and obviously remind the problem part of the equipment.

[0007] However, the current yarn guide and threading mechanisms often have problems such as poor yarn stability and consistency during the weaving process, unstable tension control, yarn entanglement and dislocation, which lead to unstable operation of the yarn machine and loose or broken yarn. In addition, the structure of the looping mechanism is relatively complex and the equipment maintenance rate is high. The needle butt and needle head are easily worn and broken, and the maintenance cost is high. Summary of the invention

[0008] The technical problem to be solved by the present invention is to improve the stability and consistency of yarn during weaving, improve the stability of tension control, reduce yarn entanglement and dislocation, improve the stability of yarn machine operation, and reduce yarn relaxation or breakage.

By setting up a linear yarn guide drive mechanism, the stability and consistency of the yarn during the weaving process can be ensured, thereby improving production efficiency. Through closed-loop control, high-precision position, speed and torque control can be achieved. This control method overcomes the problem of stepping out of step of the stepper motor and ensures the accuracy and stability of the movement. In addition, the accuracy of the servo motor drive can be achieved through the precise control of electrical parameters (such as voltage and current), and the action results are more direct and accurate.

[0011] 2. By setting up a multi-level yarn guide adjustment mechanism, the yarn is guided so that it passes smoothly from the spindle through various components and finally reaches the fabric or ribbon. At the same time, the multi-level yarn guide adjustment mechanism can also help control the tension of the yarn, prevent the yarn from being tangled and misaligned, maintain the balance and stability of the spinning machine, and prevent the spinning from being loose or broken. In addition, the tension and speed of the spinning machine can be adjusted to meet different yarn and fabric requirements.

[0012] 3. By setting the tension wheel and the tension wheel guide groove, the power in the spinning machine is transmitted to the dynamic yarn tension device through electric energy, thereby realizing the control of the yarn tension. In actual production, by adjusting the output power and speed of the motor, the yarn tension can be accurately controlled, thereby achieving the smooth operation of the yarn and the production of high-quality textiles.

[0013] 4. By setting up the shuttle top threading mechanism, during the looping process, it moves back and forth along its own length direction to weave the yarn into a coil. When the hook moves relative to the yarn, the old coil on the needle bar is used to rotate the needle tongue, close the needle mouth, and make the yarn under the needle hook and the old coil on both sides of the needle tongue respectively. As the needle moves further, the yarn passes through the old coil to form a new coil. By setting up the shuttle top threading mechanism, the structure of the looping mechanism is simplified, and the redundant actions are reduced, which not only reduces the manufacturing cost, but also reduces the equipment maintenance rate.

[0014] 5. By setting up a resilient yarn threading crochet hook, after passing the thread, it automatically drops due to the elastic force of the spring, simplifying the equipment structure. The crochet hook has a simpler structure than the latch needle and is easy to manufacture. It can weave thinner fabrics, but other loop-forming parts that cooperate with it are more complicated.

[0015] 6. By setting a round head boss, a conformal slider and a flexible guide groove, the wear parts are dispersed and the service life is extended. While increasing the machine speed, the impact force of the conformal slider on the knitting needle is reduced, and the damage to the needle butt and the needle head is reduced.

[0016] 7. By setting up the linear motor magnetic strip and conformal slider, the system structure is greatly simplified, the weight and volume are also greatly reduced, the motion inertia is reduced, the dynamic response performance and positioning accuracy are improved, the positioning error caused by the intermediate links is eliminated, the positioning accuracy is high, and since there is no mechanical connection or conversion device, the linear motor runs smoothly and the noise is extremely low.

[0017] 8. By setting the wear-resistant block, the durability and replaceability of the conformal slider are improved. When wear occurs, it is unnecessary to replace the conformal slider, but only the wear-resistant block needs to be replaced, which reduces the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

The belt (207) passes through the bottom of the sliding seat (203) and is fixed by the belt pressing plate (208), thereby driving the sliding seat (203) to move linearly along the circular guide rail (202), thereby driving the yarn guide mechanism (1) to move linearly along the circular guide rail (202); S3, the silk thread enters the plurality of yarn guide rollers (306) through the thread-passing cone (111) on the end contour wheel support (109), and then passes downward through the thread guide groove (311) on the driving wheel (309); S4, the silk thread passes through the yarn guide roller (306), winds around the tensioning wheel guide groove (319) on the tensioning wheel (318), and then enters the driving wheel (309); the tensioning wheel seat (317) is movably connected to the tensioning wheel motor (316) via a screw rod passing through the interior thereof, and the linear motion along the shaft end of the tensioning wheel motor (316) is converted into rotation along the short shaft on the yarn guide roller seat (305), thereby adjusting the silk thread tension; The position of the conformable guide block (416) in the three coordinate directions S5, X, Y, and Z can be slightly adjusted by adjusting rods movably arranged thereon. After the silk thread passes through the driving wheel (309), it enters the wire barrel (417) and then passes through the wire hole (418). The sinking cylinder (414) moves and drives the conformable guide block (416) to reach the working position when working through the movable hinge of the first hinge wall (411) and the second hinge wall (412); S6, the follower slider (515) moves linearly along the motor magnetic strip (514), and the round-head boss (513) provided at the tail of the resilient yarn threading hook needle (507) moves in the flexible guide groove (516), thereby realizing the linear movement of the spline guide rail (512) on the resilient yarn threading hook needle (507) along the guide sleeve hole (506); S7. When the resilient yarn threading hook (507) moves upward to the top, the return spring (509) is squeezed, and the yarn blocking arm (508) is disengaged from the restriction of the U-shaped closing groove (505), and is disengaged from the resilient yarn threading hook (507). At this time, the follow-up guide block (416) moves to this position, and the silk thread enters the resilient yarn threading hook (507). When the follow-up slider (515) continues to move forward, the resilient yarn threading hook (507) moves downward under the elastic force of the return spring (509), and the yarn blocking arm (508) is restricted by the U-shaped closing groove (505), and is hinged to close with the resilient yarn threading hook (507), completing a threading action.
