Description

Technical Field

[0001] The utility model relates to the technical field of textile, in particular to an anti - weft - shrinkage nozzle device. Background Art

[0002] Air - jet looms have the characteristics of high speed, high output, and high efficiency, and are widely promoted in the weaving industry. Using air - jet weft insertion relies on nozzles to eject airflows with a certain pressure and speed as the carriers for the weft yarn to fly across the shed. Under such air - jet weft - insertion conditions, if the equipment status and weaving process are set improperly, during the weft - insertion process, the flying speed of the weft yarn depends on the speed of the airflow, and the speed of the airflow is determined by the air pressure. If the air pressure is too small, too large, or unstable, it will affect the flying speed and stability of the weft yarn, making the weft yarn unable to reach the end point during a weft - insertion process. Especially when producing high - count and high - density fabrics, the influence of weft shrinkage on the weaving efficiency and product quality is particularly prominent.

[0003] In the field of textile machinery, the problem of weft shrinkage has always been a key factor affecting the quality of fabrics. Weft shrinkage refers to the shrinkage, twisting, or bending of the weft yarn during the weaving process, resulting in defects on the fabric surface and seriously affecting the product quality. There are many reasons for weft shrinkage, including inappropriate temperature, temperature fluctuations, and the characteristics of the weft yarn itself, etc.

[0004] In traditional air - jet looms, the nozzle device is mainly responsible for feeding the weft yarn into the fell of the cloth, but lacks the function of pre - treating the weft yarn. This causes the weft yarn to be affected by temperature factors before being fed into the fell of the cloth. If the textile temperature is too low, the textile thread may become hard, increasing the risk of weft shrinkage. Especially in a dry or electrostatic - rich environment, the weft yarn is easily adhered or twisted, thus affecting the quality of the fabric. Summary of the Utility Model

[0005] Aiming at the problem that the weft yarn is prone to weft shrinkage during the weaving process of the existing air - jet loom, the utility model provides an anti - weft - shrinkage nozzle device to solve the problem of weft shrinkage occurring during the weaving process of the air - jet loom.

[0006] The utility model provides an anti - weft - shrinkage nozzle device, which includes a bottom plate. Two mounting brackets are fixedly connected to the upper surface of the bottom plate. The top ends of the two mounting brackets are fixedly connected with a nozzle pipe. A nozzle is fixedly connected to the left end of the nozzle pipe. The device also includes a pre - treatment structure, and the pre - treatment structure includes an electric heating tape adhered to the inner wall of the nozzle pipe.

[0007] Further, four mounting holes are opened on the bottom plate.

[0008] Further, the pre - treatment structure includes a mounting seat and a temperature sensor. The mounting seat is fixed to the upper surface of the bottom plate at the wire - inlet end of the nozzle pipe, and the temperature sensor is installed on the inner side wall of the mounting seat.

[0009] Further, the pretreatment structure further includes an inverted U-shaped frame, which is fixed to the upper surface of the bottom plate and through which the yarn passes for limiting the yarn.

[0010] Further, the temperature sensor is electrically connected to the controller, and the controller is electrically connected to the electric heating tape. The electric heating tape heats the yarn according to the instructions of the controller.

[0011] Further, the controller is arranged on the upper surface of the bottom plate. The controller judges the state of the yarn and makes corresponding treatments.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] As Figure 1 、 Figure 2As shown in the figure, a weft shrinkage prevention nozzle device includes a bottom plate 1. Four mounting holes 2 are provided on the bottom plate 1. Two mounting brackets 4 are fixedly connected to the upper surface of the bottom plate 1. The top ends of the two mounting brackets 4 are fixedly connected to a nozzle pipe 5. The left end of the nozzle pipe 5 is fixedly connected to a nozzle 6. It further includes a pretreatment structure 3. The pretreatment structure 3 includes an electric heating tape 302 adhered to the inner wall of the nozzle pipe 5.

[0021] The pretreatment structure 3 further includes a mounting base 8, an inverted U-shaped frame 9, and a temperature sensor 301. The mounting base 8 is fixed to the upper surface of the bottom plate 1 at the wire inlet end of the nozzle pipe 5. The inverted U-shaped frame 9 is fixed to the upper surface of the bottom plate 1 and the yarn 7 passes through the inverted U-shaped frame 9 for limiting the yarn 7. The temperature sensor 301 is installed on the inner side wall of the mounting base 8. The temperature sensor 301 is an infrared temperature sensor, which is used for non-contact detection of the surface temperature of the yarn 7 at the wire inlet end of the nozzle pipe 5. The temperature sensor 301 is electrically connected to a controller 10. The controller 10 is electrically connected to the electric heating tape 302. The controller 10 is arranged on the upper surface of the bottom plate 1.

[0022] The working principle of the weft shrinkage prevention nozzle device of the present utility model is as follows:

[0023] The yarn 7 passes through the inverted U-shaped frame 9, the nozzle pipe 5, and the nozzle 6 in sequence. The yarn 7 first passes through the temperature sensor 301. The temperature sensor 301 monitors the temperature condition of the surface of the yarn 7 and transmits the data to the controller 10.

[0024] According to the data collected by the temperature sensor 301, the controller 10 judges the state of the yarn 7 and makes corresponding treatments. If it is detected that the temperature is too low, which may cause the yarn 7 to become hard and increase the risk of weft shrinkage, the controller 10 will instruct the electric heating tape 302 to work and heat the yarn 7 appropriately to make it recover to be soft.

[0025] The temperature of the yarn 7 passing through the pretreatment structure 3 is increased, reducing the risk of weft shrinkage. The yarn 7 enters the nozzle pipe 5 and is accurately sent into the fell of the cloth through the nozzle 6, completing the weaving process, effectively solving the problem that the weft yarn is prone to weft shrinkage during the weaving process of the air-jet loom and improving the fabric quality.
