Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a reflective weft probe device for a loom with a dust-proof structure. Background Technology

[0002] The weft probe is an indispensable component of a loom. It plays a crucial role in the weft insertion process, detecting whether the weft yarn has reached the predetermined position on time and accurately. This allows for automatic stopping of the loom if the weft yarn breaks, reducing defects.

[0003] During the weaving process, the friction and breakage of yarns generate a large amount of dust. This dust easily adheres to the surface of the detection components of the reflective weft detector, seriously interfering with the detection accuracy of the weft yarn and affecting the quality and efficiency of the weaving. To avoid interference with the detection components, a dust blowing structure is usually provided. Using airflow, the dust can be actively blown away from the surface of these key components, preventing dust adhesion at the source and ensuring the normal function of the components and the stability of the equipment operation.

[0004] In order for the dust blowing structure to accurately blow away the dust on the detection component, the angle of the nozzle on the dust blowing component is usually adjusted. However, adjusting the angle of most nozzles requires a complicated disassembly of the weft probe head. This operation is not only cumbersome and time-consuming, but also reduces the efficiency of adjustment to different weaving conditions. Furthermore, frequent disassembly can easily damage the overall structural stability of the weft probe head. Therefore, a weft probe head device with a dust-proof structure for looms is proposed to solve the above problems. Summary of the Invention

It aims to solve the problem that in the prior art, in order to make the dust blowing structure accurately blow off the dust on the probe, it is usually necessary to adjust the nozzle angle of the dust blowing component. However, most nozzle adjustments require complex disassembly of the weft probe, which is not only cumbersome and time-consuming, reducing the adjustment efficiency for different weaving conditions, but also easily damaging the overall structural stability of the weft probe due to frequent disassembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a weft detection head device for a weft detection machine with a dust-proof structure, comprising a weft detection head, a support column fixedly connected to the top of the outer surface of the weft detection head, a rotating shaft rotatably connected to the top of the inner surface of the support column, a fan-shaped nozzle fixedly connected to the rear of the outer surface of the rotating shaft, and an adjustment component provided on the outer surface of the support column.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a weft detector for a loom with a dust-proof structure, comprising a weft detector 1. A support column 7 is fixedly connected to the top of the outer surface of the weft detector 1, which provides a basic structure for mounting the rotating shaft 9 and the fan-shaped nozzle 6, ensuring the installation stability and operational reliability of subsequent components. The rotating shaft 9 is rotatably connected to the top of the inner surface of the support column 7, serving as the rotating carrier for the fan-shaped nozzle 6, enabling the fan-shaped nozzle 6 to achieve angle adjustment. The fan-shaped nozzle 6 is fixedly connected to the rear of the outer surface of the rotating shaft 9, which sprays airflow to blow away dust around the weft detector 1, thus preventing dust and ensuring the detection accuracy of the weft detector 1.

[0020] Reference Figure 3An adjustment component 10 is provided on the outer surface of the support column 7 to achieve precise adjustment of the spray angle of the fan-shaped nozzle 6, improving the convenience and accuracy of angle adjustment. The adjustment component 10 includes a crosshead 101, the rear of the outer surface of the crosshead 101 is fixedly connected to the front of the outer surface of the rotating shaft 9. The rotation of the crosshead 101 can directly drive the rotating shaft 9 to rotate, providing an operating position for the angle adjustment of the fan-shaped nozzle 6. A limit plate 102 is fixedly connected to the outer surface of the crosshead 101. The outer surface of the limit plate 102 is rotatably connected to the top of the outer surface of the support column 7, which plays a role in assisting in limiting and stabilizing the rotation of the crosshead 101, making the angle adjustment process smoother. The adjustment component 10 also includes a pointer 103, the outer surface of the pointer 103 is fixedly connected to the outer surface of the limit plate 102, and is used to point to the scale 104, making it easy for the operator to intuitively read the angle value of the fan-shaped nozzle 6. The top of the outer surface of the support column 7 is provided with a scale 104, which works with the pointer 103 to provide a precise scale 104 reference for the angle adjustment of the fan-shaped nozzle 6, ensuring the accuracy of the angle adjustment.

[0021] Reference Figure 3 A threaded sleeve 12 is fixedly connected to the top of the outer surface of the support column 7, providing a base for the threaded connection of the fixing bolt 11, allowing the fixing bolt 11 to move up and down to fix the rotating shaft 9. The inner surface of the threaded sleeve 12 is threaded through and connected to the fixing bolt 11. By rotating the fixing bolt 11, the rubber pad 13 can be moved up and down, thereby fixing or loosening the rotating shaft 9. The bottom of the outer surface of the fixing bolt 11 is rotatably connected to the top of the inner surface of the support column 7, ensuring that the fixing bolt 11 only moves axially when rotating, without circumferential displacement, thus improving the stability of the structure. The bottom of the outer surface of the fixing bolt 11 is fixedly connected to the rubber pad 13. Utilizing the elasticity and friction of the rubber pad 13, it can provide sufficient fixing force when fixing the rotating shaft 9, while avoiding hard damage to the surface of the rotating shaft 9. The bottom of the outer surface of the rubber pad 13 is in contact with the top of the outer surface of the rotating shaft 9. Through contact with the surface of the rotating shaft 9, the axial fixing of the rotating shaft 9 is achieved, ensuring the stability of the angle of the fan-shaped nozzle 6 after adjustment.

[0022] Reference Figures 1-3An air pipe 8 is fixedly connected to the right side of the outer surface of the fan-shaped nozzle 6, which is used to deliver the airflow from the external air source to the fan-shaped nozzle 6, providing the power source for the fan-shaped nozzle 6 to blow dust. The outer surface of the air pipe 8 is fixedly connected to the outer surface of the weft detector 1, which serves to fix the air pipe 8 and prevent it from shaking or falling off during operation, ensuring the stability of the airflow delivery. A receiver 3 is fixedly connected to the left side of the inner surface of the weft detector 1, which is used to receive detection signals and realize the detection function of the weft yarn of the loom, ensuring the normal operation of the weaving process. A protrusion 5 is fixedly connected to the right side of the outer surface of the weft detector 1, which is used to provide a stable light source and emit a directional beam of light to the "predetermined weft yarn path" in the weaving area. An interface 2 is fixedly connected to the front of the outer surface of the weft detector 1, which is used to realize the circuit or signal connection between the weft detector 1 and the external equipment, ensuring the power supply and signal transmission of the weft detector 1. A fixing seat 4 is fixedly connected to the bottom of the outer surface of the weft detector 1, which is used to fix the weft detector 1 in a designated position on the loom, ensuring the positional stability of the weft detector 1 during operation.

[0023] Working principle: When it is necessary to adjust the spray angle of the fan-shaped nozzle 6, first loosen the fixing bolt 11 upwards so that the rubber pad 13 at the bottom of the fixing bolt 11 stops contacting the surface of the rotating shaft 9, thereby releasing the axial fixation of the rotating shaft 9. Then, use a Phillips screwdriver to insert into the Phillips slot on the Phillips head 101 and rotate the Phillips head 101 to drive the rotating shaft 9 to rotate, which in turn drives the fan-shaped nozzle 6 to rotate along the inside of the support column 7, thereby adjusting the spray angle of the fan-shaped nozzle 6. During adjustment, the pointer 103 and scale 104 on the limit plate 102 fixed on the Phillips head 101 can be observed to accurately adjust the spray angle of the fan-shaped nozzle 6. After the adjustment is completed, tighten the fixing bolt 11 downwards so that the rubber pad 13 at the bottom of the fixing bolt 11 contacts the surface of the rotating shaft 9, so that the rotating shaft 9 is axially fixed by the squeezing friction of the rubber pad 13, thereby fixing the adjusted angle of the fan-shaped nozzle 6.
