Description

[0002] The air jet loom is a shuttleless loom that uses a jet of air to pull the weft yarn through the shed. The air jet loom uses air as the weft insertion medium, and uses the ejected compressed air flow to generate friction traction on the weft yarn to pull it, bringing the weft yarn through the shed, and achieving the purpose of weft insertion through the jet generated by the air jet. Compared with water jet, gas has higher fluidity and compression performance, which will make the weft yarn obtain a higher initial velocity, so that the loom can work faster. The air jet loom has the characteristics of high speed and high yield, wide variety adaptability, low machine material consumption, high efficiency, high speed, and low noise. It is suitable for the production of various fabrics such as cotton fabrics, denim, feather fabrics, yarn-dyed fabrics, medium and long imitation wool, elastic fabrics, and towel fabrics.

[0003] The production process of tire cord fabric includes twisting, weaving, and dipping. During the weaving process, a special tire cord fabric air jet loom is used, which can be precisely controlled and operated. However, due to the limited space between the folding block and the scissors, the weft yarn flies to the rightmost weaving opening without any guidance, and the airflow diverges. The weft yarn is easy to float to the back of the special-shaped reed, causing the short weft to stop, thus affecting the weaving efficiency.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] It should be noted that the directional words such as "left" and "right" below are defined based on the drawings in the specification.

[0040] The core of the present invention is to provide a weft end processing device, which is arranged at the right end of the weft 01, so that the weft 01 continues to fly along the conveying direction after flying to the rightmost weft outlet, which can avoid the short weft stop caused by air flow divergence. Another core of the present invention is to provide a tire cord fabric air jet loom including the above-mentioned weft end processing device, which 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.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3 A weft yarn end processing device includes a frame 1 and a fixed guiding mechanism 2, a swing guiding mechanism 3, a short weft feeler 4, an extension spray mechanism 5 and an auxiliary nozzle mechanism 6 which are sequentially installed on the frame 1 along the conveying direction of the weft yarn 01. The fixed guiding mechanism 2 and the swing guiding mechanism 3 are provided to guide the conveyed weft yarn 01. The short weft feeler 4 is provided to detect in real time whether there is a weft yarn 01 at the current position, so as to judge whether a short weft problem occurs. The extension spray mechanism 5 is provided to pull the weft yarn 01 guided by the fixed guiding mechanism 2 and the swing guiding mechanism 3 to prevent weft shrinkage. The auxiliary nozzle mechanism 6 is provided to increase the tensile force of the swing guiding mechanism 3 on the weft yarn 01.

[0042] The swinging 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 wire conveying channel 311 for the weft yarn 01 to pass through. The weft yarn 01 is conveyed by the wire conveying channel 311 on the shaped reed 31. At the same time, the wire conveying channel 311 can guide the airflow conveying the 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 swinging guide reed 32 for guiding the direction of the weft yarn 01. The swinging guide reed 32 is provided with a guide groove 321. The weft yarn 01 is effectively guided by setting the swinging guide reed 32. The guide groove 321 on the swinging guide reed 32 is used to effectively guide the airflow, thereby avoiding airflow dispersion and achieving guidance of the weft yarn 01, so that the problem of short weft parking caused by airflow dispersion will not occur.

[0043] The surface of the special-shaped reed 31 is recessed inward to form a wire transmission channel 311 .

[0044] The weft yarn end processing device arranged in the above manner can effectively solve the short weft stop caused by air flow divergence after the right weft yarn 01 exits the weaving mouth during the weaving process of tire cord cloth, and can significantly improve the weaving efficiency of various varieties in the tire cord cloth industry, save energy and increase production for the industry, and reduce the labor intensity of workers.

[0045] In the above embodiment, the swinging guide mechanism 3 also includes a swinging base 33 which is swingably arranged on the frame 1, and the swinging base 33 extends along the conveying direction of the weft yarn 01. The swinging guide reed 32 is adjustably arranged on the swinging base 33. The swinging base 33 is driven by a driving device so that the swinging base 33 swings within a certain range, and the driving device is connected to the controller signal.

[0046] It should be noted that the driving device is controlled by the controller to operate so as to drive the swing base 33 to swing, thereby driving the swing guide reed 32 to swing synchronously.

[0047] Among them, 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, the screws are loosened and the swing guide reed 32 is moved along the length direction of the swing base 33. After moving into position, the screws are tightened to fix the swing guide reed 32 on the swing base 33. The swing base 33 is provided with a waist-shaped long hole for adjusting the position of the swing guide reed 32, which cooperates with the screws to achieve locking of the swing guide reed 32.

[0048] In the above situation, the fixed guide mechanism 2 includes a fixed guide reed 21, which is connected to the locking block 23 through a connecting structure 22, and the locking block 23 is connected to the trapezoidal iron 24, which is fixed to the frame 1, and the fixed guide reed 21 is located in the notch 312, and the guide groove 211 of the fixed guide reed 21 is corresponding to the wire transmission channel 311 of the special-shaped reed 31.

[0049] It can be understood that the fixed guide reed 21 is connected to the trapezoidal iron 24 through the locking block 23, and the guide groove 211 of the fixed guide reed 21 is aligned with the wire transmission channel 311 of the loom at 180°.

[0050] In the present 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 wire transmission channel 311 are aligned, that is, the position of the loom at 180°, and the maximum swing position is the front dead center position. During the operation of the loom, the fixed guide reed 21 periodically swings back and forth 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 arranged 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 to operate so that the scissors 71 of the cutting mechanism 7 cut the weft yarns in the yarn conveying channel 311 .

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

[0054] It can be understood that the motor is controlled by the controller to drive the scissors 71 to open and close. When the loom reaches the front dead center, the scissors 71 are just inserted into the opening 322 on the swing guide reed 32 without interference, that is, the spatial area A. In the absence of 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 position of the swing guide reed 32 is moved along the swing base 33 by loosening the screws to shorten the distance between the swing guide reed 32 and the folding block 72.

[0055] Please refer to Figure 1 , Figure 5 and Figure 6 The short weft feeler 4 is arranged on the swing base 33 and is located at the rear end of the swing guide reed 32. The detection end of the short weft feeler 4 faces the wire conveying channel 311. The short weft feeler 4 is used for detecting in real time whether there is a weft yarn 01 in the wire conveying channel 311 at the current position, and sending 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 a weft yarn 01 in the line transmission channel 311 at the current position, and send the detected signal to the controller, and the operating state of the loom is controlled by the controller.

[0057] In the above embodiment, the extension spray mechanism 5 is arranged on the swing base 33 and is located at the rear end of the short weft feeler 4. The extension spray mechanism 5 is connected to the high-pressure air pump through an air pipeline. The high-pressure air pump is connected to the air source. The high-pressure air pump is arranged on the frame 1 and is connected to the controller signal. A first solenoid valve connected to the controller signal is provided on the air pipeline.

[0058] It can be understood that the extension spray mechanism 5 is fixed on the swing base 33, swings synchronously with the swing base 33, and is located on the right side of the short weft feeler 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 feeler 4.

[0059] The operating state of the high-pressure air pump is controlled by a controller to deliver the gas of the air source to the nozzle of the extension spray mechanism 5 through the gas pipeline. The gas is sprayed from the nozzle to pull the weft yarn 01 guided by the fixed guide mechanism 2 and the swing guide mechanism 3 to prevent weft shrinkage. The opening of the first solenoid valve is controlled by the controller 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 arranged on the swing base 33, the auxiliary nozzle mechanism 6 is connected to the high-pressure air pump through the air pipeline, the high-pressure air pump is connected to the air source, and the air pipeline is provided with a second solenoid valve connected to the controller signal.

[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 operating state of the high-pressure air pump is controlled by the controller to transport the gas of the air source to the nozzle of the auxiliary nozzle mechanism 6 through the gas pipeline. The gas is ejected from the nozzle to increase the tensile force of the swing guide mechanism 3, pull the weft yarn 01 guided by the swing guide mechanism 3, and prevent weft shrinkage. The opening of the second solenoid valve is controlled by the controller, thereby controlling the intensity of the gas ejected from the nozzle.

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

[0063] It can be understood that the auxiliary nozzle mechanism 6 includes three auxiliary nozzles, one auxiliary nozzle is arranged on the left and right of the swing guide mechanism 3, and the other auxiliary nozzle is arranged on the right side of the extension nozzle mechanism 5. The operating state of the high-pressure air pump is controlled by the controller to transport the gas of the air source to the auxiliary nozzle through the gas pipeline. The gas is ejected from the auxiliary nozzle to pull 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 fabric jet loom includes the above-mentioned weft yarn end processing 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 line transmission direction of the line transmission channel 311, the main nozzle is connected to the high-pressure air pump through an air transmission pipeline, the high-pressure air pump is connected to the main air source, and a third solenoid valve connected to the controller signal is provided on the air transmission pipeline.

[0065] It should be noted that the operating state of the high-pressure air pump is controlled by a controller to transport the gas of the main air source to the main nozzle of the airflow weft insertion mechanism through the air pipeline. The gas is ejected from the main nozzle to drive the weft thread to move from left to right along the line transmission channel 311. The opening of the third solenoid valve is controlled by the controller to control the intensity of the gas ejected from the nozzle, thereby controlling the speed of the weft thread movement.

[0066] In addition to the air-jet loom for cord fabric disclosed in the above-mentioned embodiments, the structures of other parts of the air-jet loom for cord fabric refer to the prior art and will not be described in detail herein.

[0067] In summary, the weft yarn end processing device provided by the present invention controls the operation of the high-pressure air pump through a controller, so that the main air source provides airflow for the movement of the weft line, so that the weft line moves from left to right along the line transmission channel 311. When the weft yarn 01 moves to the notch 312 of the special-shaped 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, and the airflow will not be dispersed at the notch 312. At the same time, the extension spray mechanism 5 and the auxiliary nozzle mechanism 6 are controlled by the controller to operate so as to pull the weft yarn 01 guided by the fixed guide reed 21 and the swing guide reed 32 to prevent weft shrinkage. At the same time, the short weft feeler 4 is used to detect in real time whether there is weft yarn 01 at the current position, so as to determine whether a short weft problem occurs. When the short weft feeler 4 does not detect that there is weft yarn 01 at the current position, the short weft feeler 4 can detect whether there is weft yarn 01 at the current position. When the short weft feeler 4 detects the weft yarn 01 at the current position, the controller controls the driving device to operate, so as to drive the swing base 33 to swing, and at the same time drive the profiled reed 31 and the swinging guide reed 32 to swing forward synchronously, so that the scissors 71 of the cutting mechanism 7 are inserted into the opening 322 of the swinging guide reed 32. The scissors 71 are in the open state in the initial state, and the controller controls the motor to drive the scissors 71 to close and cut the weft. After the weft is cut, the motor is controlled to drive the scissors 71 to open, and at the same time the driving device drives the swing base 33 to swing, and at the same time drives the profiled reed 31 and the swinging guide reed 32 to swing backward synchronously to the initial position, that is, the position where the fixed guide reed 21 is aligned with the profiled reed 31. Repeat this process to achieve the textile operation of the loom.

[0068] The present application sets a fixed guiding mechanism 2 and a swinging guiding mechanism 3 on the notch 312 of the special-shaped reed 31, which can guide the airflow conveying the weft yarn 01, avoid airflow dispersion, and guide the weft yarn 01, thereby avoiding the problem of short weft parking caused by airflow dispersion. It can effectively solve the problem of short weft parking caused by airflow divergence after the right side weft yarn 01 leaves the weaving mouth during the weaving process of tire cord cloth, and can significantly improve the weaving efficiency of various varieties in the tire cord cloth 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, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
