[0002] The air-jet loom is a shuttleless loom which uses jet air flow to pull the weft yarn through the shed. The air-jet loom uses air as the weft medium, and uses the frictional traction force of the jet air flow to pull the weft yarn, so as to bring the weft yarn through the shed. Compared with water jet, air has higher flowability and compression performance, so that the weft yarn can obtain a higher initial speed, and thus the loom can work faster. The air-jet loom has the characteristics of high speed and high yield, wide variety adaptability, low material consumption, high efficiency, high speed, low noise, etc., and is suitable for the production of various fabrics such as cotton fabric, denim, feather fabric, yarn-dyed fabric, medium-long wool-like fabric, elastic fabric, and towel fabric.

[0003] The production process of the tire harness cloth includes twisting, weaving, and dipping. In the weaving process, a special harness cloth air-jet loom is used for accurate control and operation. However, due to the limitation of the folding block and the shears, the weft yarn flies to the rightmost side of the weaving port, and then due to the lack of guiding effect, the air flow is dispersed, the weft yarn is easily floated to the rear side of the special reed, and short weft stop occurs, thereby affecting the weaving efficiency.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] It should be noted that the directional terms such as "left" and "right" in the following text are defined based on the accompanying drawings in the instruction manual.

[0040] The core of this invention is to provide a weft yarn end treatment device, arranged at the right end of the weft yarn 01, so that after the weft yarn 01 flies to the rightmost exit of the weaving, it continues to fly along the conveying direction, which can avoid short weft stopping caused by airflow divergence. Another core aspect of this invention is to provide a tire cord fabric air-jet loom including the above-mentioned weft yarn end treatment device, which can significantly improve the weaving efficiency of various products in the tire cord fabric industry, save energy and increase production for the industry, and reduce the labor intensity of workers.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3 A weft yarn end processing device includes a frame 1 and a fixed guide mechanism 2, a swing guide mechanism 3, a short weft detector 4, an extension spray mechanism 5, and an auxiliary nozzle mechanism 6, which are sequentially installed on the frame 1 along the weft yarn 01 conveying direction. By setting the fixed guide mechanism 2 and the swing guide mechanism 3, the conveyed weft yarn 01 is guided. By setting the short weft detector 4, the presence of weft yarn 01 at the current position is detected in real time to determine whether a short weft problem has occurred. By setting the extension spray mechanism 5, the weft yarn 01 guided by the fixed guide mechanism 2 and the swing guide mechanism 3 is pulled to prevent weft shrinkage. By setting the auxiliary nozzle mechanism 6, the tension of the swing guide mechanism 3 on the weft yarn 01 is increased.

[0042] The swing guide mechanism 3 includes a shaped reed 31 extending along the conveying direction of the weft yarn 01. The shaped reed 31 is provided with a thread conveying channel 311 for the weft yarn 01 to pass through. The weft yarn 01 is conveyed through the thread conveying channel 311 on the shaped reed 31. At the same time, the thread conveying channel 311 can guide the airflow of the conveying weft yarn 01 to avoid airflow dispersion. The rear end of the shaped reed 31 has a notch 312. The notch 312 is provided with a swing guide reed 32 for guiding the direction of the weft yarn 01. The swing guide reed 32 is provided with a guide groove 321. By setting the swing guide reed 32, the weft yarn 01 is effectively guided. The guide groove 321 on the swing guide reed 32 effectively guides the airflow, thereby avoiding airflow dispersion and guiding the weft yarn 01, thus preventing the short weft stopping problem caused by airflow dispersion.

[0043] Among them, the surface of the irregular reed 31 is recessed inward to form a transmission channel 311.

[0044] The weft yarn end treatment device set up in the above manner can effectively solve the problem of short weft stopping caused by airflow dispersion after the right weft yarn 01 exits the weaving port during the tire cord fabric weaving process. It can significantly improve the weaving efficiency of various varieties in the tire cord fabric industry, save energy and increase production for the industry, and reduce the labor intensity of workers.

[0045] In the above embodiment, the swing guide mechanism 3 further includes a swing base 33 that can swing and is disposed on the frame 1. The swing base 33 extends along the weft yarn 01 conveying direction. The swing guide reed 32 is adjustablely disposed on the swing base 33. The swing base 33 is driven by a drive device to swing within a certain range. The drive device is signal-connected to the controller.

[0046] It should be noted that the controller controls the operation of the drive device to drive the swing base 33 to swing, thereby driving the swing guide reed 32 to swing synchronously.

[0047] The position of the swing guide reed 32 on the swing base 33 is adjustable. The swing guide reed 32 is fixed to the swing base 33 by screws. When it is necessary to adjust the position of the swing guide reed 32 on the swing base 33, loosen the screws and move the swing guide reed 32 along the length of the swing base 33. After it is moved into place, tighten the screws to fix the swing guide reed 32 on the swing base 33. The swing base 33 is provided with an oblong hole for adjusting the position of the swing guide reed 32. With the screws, the swing guide reed 32 can be locked.

[0048] In the above case, the fixed guide mechanism 2 includes a fixed guide reed 21, which is connected to a locking block 23 via a connecting structure 22. The locking block 23 is connected to a trapezoidal iron 24, which is fixed to the frame 1. The fixed guide reed 21 is located in the notch 312, and the guide groove 211 of the fixed guide reed 21 is correspondingly provided with the wire transmission channel 311 of the irregular reed 31.

[0049] It is understandable that the fixed guide reed 21 is connected to the trapezoidal iron 24 by the locking block 23, and the guide groove 211 of the fixed guide reed 21 is aligned with the thread feeding channel 311 of the loom at 180°.

[0050] In this application, the initial position of the weft yarn end processing device is the position when the guide groove 211 of the fixed guide reed 21 and the yarn feeding channel 311 are aligned, which is the position of the loom at 180°. The maximum swing position is the front dead center position. During the operation of the loom, the fixed guide reed 21 swings back and forth periodically between the initial position and the front dead center position.

[0051] Furthermore, it also includes a cutting mechanism 7 connected to the controller signal. The cutting mechanism 7 is mounted on the frame 1, and the cutting direction of the cutting mechanism 7 is perpendicular to the guiding direction of the swing guide reed 32.

[0052] It should be noted that the cutting mechanism 7 is controlled by the controller so that the shears 71 of the cutting mechanism 7 cut the weft thread of the transmission channel 311.

[0053] Please refer to Figure 2 ,Figure 4 and Figure 5 The cutting mechanism 7 includes scissors 71 fixed to trapezoidal iron 24 and folding block 72. Folding block 72 is correspondingly set with fixed guide reed 21. The swing guide reed 32 is provided with an opening 322 corresponding to scissors 71 so that scissors 71 can be inserted into the opening 322. Scissors 71 is connected to a motor, and the motor is connected to a controller signal. The motor is used to drive the opening and closing of scissors 71.

[0054] Understandably, the controller controls the motor to open and close the scissors 71. When the loom reaches the front center, the scissors 71 are inserted into the opening 322 on the swing guide reed 32 without interference, which is space area A. Under the condition of no interference, the distance between the swing guide reed 32 and the folding block 72 is shortened as much as possible to ensure a stable weft insertion effect. The distance between the swing guide reed 32 and the folding block 72 is shortened by loosening the screw and moving the position of the swing guide reed 32 along the swing base 33.

[0055] Please refer to Figure 1 , Figure 5 and Figure 6 The short weft detector 4 is located on the swing base 33 and at the rear end of the swing guide reed 32. The detection end of the short weft detector 4 faces the transmission channel 311. The short weft detector 4 is used to detect in real time whether there is weft yarn 01 in the transmission channel 311 at the current position, and sends the detection signal to the controller.

[0056] It should be noted that the short weft detector 4 is used to detect in real time whether there is weft yarn 01 in the current position of the feed channel 311, and sends the detected signal to the controller, which controls the operation status of the loom.

[0057] In the above embodiment, the extension spraying mechanism 5 is located on the swing base 33 and at the rear end of the short weft detector 4. The extension spraying mechanism 5 is connected to the high-pressure air pump through the air supply pipe. The high-pressure air pump is connected to the air source. The high-pressure air pump is located on the frame 1 and is connected to the controller signal. The air supply pipe is equipped with a first solenoid valve that is connected to the controller signal.

[0058] It is understandable that the extension spray mechanism 5 is fixed on the swing base 33 and swings synchronously with the swing base 33. It is located on the right side of the short weft detector 4. Its function is to pull the weft yarn 01 guided by the fixed guide mechanism 2 and the swing guide mechanism 3 to prevent weft shrinkage, thereby preparing for the accurate detection of the short weft detector 4.

[0059] The controller controls the operation of the high-pressure air pump to deliver the gas from the air source to the nozzle of the extension spray mechanism 5 through the air pipeline. The gas is sprayed out from the nozzle to hold the weft yarn 01 guided by the fixed guide mechanism 2 and the swing guide mechanism 3 to prevent weft shrinkage. The controller controls the opening of the first solenoid valve to control the intensity of the gas sprayed from the nozzle.

[0060] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The auxiliary nozzle mechanism 6 is located on the swing base 33. The auxiliary nozzle mechanism 6 is connected to the high-pressure air pump through the air supply pipe. The high-pressure air pump is connected to the air source. A second solenoid valve connected to the controller signal is provided on the air supply pipe.

[0061] It should be noted that the auxiliary nozzle mechanism 6 is fixed on the swing base 33 and swings synchronously with the swing base 33. The function of the auxiliary nozzle mechanism 6 is to increase the tensile force of the swing guide mechanism 3. The controller controls the operation of the high-pressure air pump to deliver the gas from the air source to the nozzle of the auxiliary nozzle mechanism 6 through the air pipeline. The gas is sprayed out from the nozzle to increase the tensile force of the swing guide mechanism 3, hold the weft yarn 01 guided by the swing guide mechanism 3 to prevent weft shrinkage. The controller controls the opening of the second solenoid valve to control the intensity of the gas sprayed from the nozzle.

[0062] In the above case, the auxiliary nozzle mechanism 6 includes three auxiliary nozzles, two of which are located at the front and rear ends of the swing guide reed 32, and the other auxiliary nozzle is located at the rear end of the extension spray mechanism 5. The outlet direction of the auxiliary nozzles is perpendicular to the transmission direction of the transmission channel 311.

[0063] It is understood that the auxiliary nozzle mechanism 6 includes three auxiliary nozzles. One auxiliary nozzle is arranged on the left and right sides of the swing guide mechanism 3, and the other auxiliary nozzle is located on the right side of the extension spray mechanism 5. The high-pressure air pump is controlled by the controller to deliver the gas from the air source to the auxiliary nozzle through the air supply pipeline. The gas is sprayed out from the auxiliary nozzle to hold the weft yarn 01 guided by the fixed guide mechanism 2 and the swing guide mechanism 3 to prevent weft shrinkage.

[0064] A tire cord air-jet loom includes the aforementioned weft yarn end treatment device and an airflow weft insertion mechanism. The airflow weft insertion mechanism includes a main air source and a main nozzle. The outlet direction of the main nozzle is parallel to the transmission direction of the yarn transmission channel 311. The main nozzle is connected to a high-pressure air pump through an air transmission pipe. The high-pressure air pump is connected to the main air source. A third solenoid valve connected to the controller signal is provided on the air transmission pipe.

[0065] It should be noted that the controller controls the operation of the high-pressure air pump to deliver the gas from the main air source to the main nozzle of the airflow weft insertion mechanism through the air delivery pipeline. The gas is ejected from the main nozzle to drive the weft yarn to move from left to right along the yarn delivery channel 311. The controller controls the opening of the third solenoid valve to control the intensity of the gas ejected from the nozzle, thereby controlling the speed of the weft yarn movement.

[0066] In addition to the air-jet loom for cord fabric disclosed in the above embodiments, the structure of other parts of the air-jet loom for cord fabric can be found in the prior art, and will not be described in detail here.

[0067] In summary, the weft yarn end processing device provided by this invention controls the operation of a high-pressure air pump through a controller, so that the main air source provides airflow for the movement of the weft yarn, causing the weft yarn to move from left to right along the yarn conveying channel 311. When the weft yarn 01 moves to the notch 312 of the irregular reed 31, the airflow is guided by the guide groove 211 of the fixed guide reed 21 and the guide groove 321 of the swing guide reed 32, preventing the airflow from dispersing at the notch 312. At the same time, the controller controls the operation of the extension spray mechanism 5 and the auxiliary nozzle mechanism 6 to hold the weft yarn 01 guided by the fixed guide reed 21 and the swing guide reed 32, preventing weft shrinkage. Meanwhile, the short weft detector 4 detects in real time whether there is a weft yarn 01 at the current position, thereby determining whether a short weft problem has occurred. When the short weft detector 4 does not detect a weft yarn 01 at the current position... When yarn 01 is in the loop, the short weft detector 4 sends a signal to the controller, which stops the loom. When the short weft detector 4 detects weft yarn 01 at the current position, the controller controls the drive unit to operate, causing the swing base 33 to swing. Simultaneously, the shaped reed 31 and the swing guide reed 32 swing forward synchronously, so that the scissors 71 of the cutting mechanism 7 inserts into the opening 322 of the swing guide reed 32. The scissors 71 are initially in the open state. The controller controls the motor to drive the scissors 71 to close, cutting the weft yarn. After cutting the weft yarn, the controller controls the motor to drive the scissors 71 to open, and the drive unit drives the swing base 33 to swing. Simultaneously, the shaped reed 31 and the swing guide reed 32 swing backward synchronously to the initial position, which is the position where the fixed guide reed 21 and the shaped reed 31 are aligned. This process is repeated to achieve the weaving operation of the loom.

[0068] This application, by setting a fixed guiding mechanism 2 and a swing guiding mechanism 3 on the notch 312 of the irregular reed 31, can guide the airflow of the conveying weft yarn 01, avoid airflow dispersion, and guide the weft yarn 01. This will prevent the short weft stopping problem caused by airflow dispersion, effectively solving the short weft stopping problem caused by airflow dispersion after the right weft yarn 01 exits the weaving port in the tire cord fabric weaving process. It can significantly improve the weaving efficiency of various products in the tire cord fabric industry, save energy and increase production for the industry, and reduce the labor intensity of workers.

[0069] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0070] The foregoing has provided a detailed description of the weft yarn end processing device and the air-jet loom for tire cord fabric provided by the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
