Description

Technical Field

[0001] The utility model relates to the field of fabric detection, and particularly relates to a photoelectric switch capable of detecting two fabrics simultaneously. Background Technique

[0002] A photoelectric switch is a device used to detect the presence or position of an object, which is realized through optical principles. When detecting two fabrics, different methods can be adopted. First, by detecting the light transmittance or reflectivity of the fabric, the photoelectric switch can distinguish their characteristics, because different fabrics may have different optical properties. Second, some photoelectric switches can identify different types of fabrics according to the color reflected by the fabric, especially when there are obvious differences in the fabric colors.

[0003] In the modern textile production process, fabric detection is a key link to ensure product quality. At present, traditional fabric detection devices can usually only detect a single type of fabric, which is inefficient and cannot meet the production requirements when the production line needs to process multiple fabrics simultaneously. Therefore, it is of great practical significance to design a photoelectric switch capable of detecting two fabrics simultaneously. Summary of the Invention

[0004] The problem to be solved by the utility model is to provide a photoelectric switch capable of detecting two fabrics simultaneously, so as to solve the problem in the prior art that only a single fabric can be detected, and improve production efficiency and detection accuracy.

[0005] The technical solution adopted by the utility model to solve the above problems is a photoelectric switch capable of detecting two fabrics simultaneously, including a switch housing, an installation groove is opened on the switch housing, at least one photoelectric sensor is provided on each of the two side walls of the installation groove, a double-sided reflector is arranged between the two side walls, the double-sided reflector has two reflecting surfaces, wherein one of the reflecting surfaces is arranged perpendicular to the photoelectric sensor, a detection channel is formed between the photoelectric sensor and the reflecting surface, a light-transmitting sheet is arranged between the detection channel and the photoelectric sensor, the photoelectric sensor is electrically connected to a circuit board and a connector in sequence, and a detection module is further arranged on the circuit board.

[0006] Preferably, a light source groove is opened on the side wall of the installation groove, the opening of the light source groove points to the reflecting surface of the double-sided reflector, the light-transmitting sheet is installed at the opening of the light source groove to enclose the light source cavity to form a containing cavity, and its upper end surface is flush with the side wall of the installation groove, and a photoelectric sensor is installed in the containing cavity.

[0007] Preferably, the material of the light-transmitting sheet is borosilicate glass.

[0008] Preferably, a clamping groove is formed in the middle of the bottom surface of the installation groove. One end of the double-sided reflector is clamped in the clamping groove, and the two reflecting surfaces of the double-sided reflector are equidistant from the optoelectronic sensors installed on the two side walls.

[0009] Preferably, the double-sided reflector is made of stainless steel, and its two sides are polished into mirror surfaces.

[0010] Preferably, a fillet is provided around the double-sided reflector.

[0011] Beneficial effects: The design of dual-channel detection has two detection channels arranged inside the switch housing. Each channel is equipped with an optoelectronic sensor and the reflecting surface of the double-sided reflector, enabling the simultaneous detection of the characteristics of two types of fabrics. This design allows the switch to handle two different detection tasks at the same time, improving efficiency and versatility.

[0012] Accurate detection: The mirror polishing of the reflector ensures a smooth reflecting surface, and the borosilicate glass material of the light-transmitting sheet guarantees optical transparency, enabling the optoelectronic sensor to accurately emit or receive reflected light signals, thereby accurately identifying the characteristics of the fabric.

[0013] The double-sided reflector made of stainless steel has good corrosion resistance and mechanical strength, making it suitable for long-term stable operation. In addition, the designed fillets and the clamping groove fixing method of the reflector ensure the stable installation and reliability of the components. The optimized design of the light source groove and the light-transmitting sheet forms a receiving cavity, effectively isolating and blocking the accumulation of residual lint on the optoelectronic sensor during the fabric movement detection process, ensuring the stability of the sensor.
