Description
Technical Field
[0001] This utility model relates to the field of protective equipment technology, and in particular to a photoelectric sensor protective device. Background Technology
[0002] In the textile industry, photoelectric sensors are key components for material positioning and operation monitoring of textile machines. Especially in the cotton feeding box area of the carding machine, it is necessary to sense the amount of cotton being transported and the position of the equipment in real time to ensure the stable operation of the machine and the accuracy of the products. However, the photoelectric sensors in the cotton feeding box area of the current carding machine are mostly exposed without effective protection or with poor protection: this area is a high-frequency area for operators to add materials and clean, and their limbs and tools are easy to collide with or snag the sensors; moreover, cotton lint and dust need to be cleaned regularly, and improper operation can easily lead to sensor displacement or damage. Some companies have attempted to install die-cast steel protective covers with openings corresponding to the sensing path, but this method has significant drawbacks: First, the steel plates are heavy, and long-term use can easily cause the mounting base to loosen, increasing the risk of displacement; second, the strong sealing makes it difficult for the heat generated by the equipment in the carding machine's feeding box area to dissipate, accelerating the aging of sensor components. High-temperature environments will accelerate the aging of the internal electronic components of the sensor, shortening its lifespan; third, the direct, complete coverage protection method requires complete disassembly during maintenance, making the maintenance process cumbersome. Therefore, a simple photoelectric sensor protection device was designed, which can not only house the photoelectric sensor and provide protection, but also has a built-in cooling mechanism that can achieve airflow exchange and cooling as needed. Utility Model Content
[0003] In view of the shortcomings of the above-mentioned traditional methods, the purpose of this utility model is to provide a photoelectric sensor protection device, which can not only be used to house photoelectric sensors and provide protection, but also has a built-in cooling mechanism that can realize airflow exchange and cooling as needed.
[0004] The technical implementation scheme of this utility model is as follows: A protective device for a photoelectric sensor includes a protective support, a sealing gasket, a photoelectric sensor, a sealing cover, and a gas guiding mechanism. The protective support is a rectangular cavity structure with an opening at the top, and the sealing gasket and the photoelectric sensor are disposed inside the protective support. The sealing cover is disposed at the top of the protective support, and an acrylic glass window is movably disposed inside the rectangular opening of the sealing cover. The gas guiding mechanism is disposed inside the protective support. The gas guiding mechanism includes a gas guiding channel, a storage platform, a first gas guiding port, a second gas guiding port, and a flow guide. The storage platform is disposed on the sealing gasket, and the storage platform and the inner wall of the sealing gasket form a gas guiding channel. The first gas guiding port and the second gas guiding port are symmetrically disposed on the protective support, and a flow guide and a filter screen are respectively disposed inside the first gas guiding port and the second gas guiding port.
[0005] Optionally, the storage platform is provided with a placement slot, and the photoelectric sensor is installed inside the storage platform; the outer wall of the storage platform is provided with a plurality of first air guide holes.
[0006] Optionally, the sealing gasket is provided with second air guide holes on both sides, and the second air guide holes are provided corresponding to the first air guide port.
[0007] Optionally, the air guide is provided with an air guide fan; the interior of the second air guide port is provided with a dehumidification layer.
[0008] Optionally, one end of the protective support is provided with a connection hole, and a connector for connecting to a photoelectric sensor is provided in the connection hole.
[0009] Optionally, the sealing cover is fixedly connected to the protective support by screws.
[0010] Optionally, the bottom of the protective support is provided with a connecting base, and the connecting block on the upper part of the connecting base is provided with a connecting through hole.
[0011] This utility model has the following advantages: 1. This utility model has a sealing gasket inside the protective support, and a photoelectric sensor is installed in the storage platform on the sealing gasket. It has a double protection effect, which prevents the operator from touching the sensor during cleaning, causing it to shift or be damaged, and improves the protection effect.
[0012] 2. In this utility model, a sealing cover is provided on the upper part of the protective support, and a rectangular opening is provided on the sealing cover. An acrylic glass window is rotatably installed inside the opening, corresponding to the photoelectric sensor. This not only does not affect its normal operation, but also provides a protective effect. Furthermore, the rotatable design of the acrylic glass window facilitates maintenance by the operator.
[0013] 3. In this utility model, an air guiding mechanism is provided inside the protective support. The air guide is activated as needed to exchange the hot airflow in the storage platform area, thereby discharging the hot air generated when the photoelectric sensor is working and achieving cooling.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0021] like Figures 1-5 As shown, a photoelectric sensor protection device includes a protective support 1, a sealing gasket 9, a photoelectric sensor 8, a sealing cover 3, and a gas guiding mechanism 7. The protective support 1 is a rectangular cavity structure with an opening at the top, and the sealing gasket 9 and the photoelectric sensor 8 are disposed inside the protective support 1. The sealing cover 3 is disposed at the top of the protective support 1, and an acrylic glass window 4 is movably disposed inside the rectangular opening of the sealing cover 3. The gas guiding mechanism 7 is disposed inside the protective support 1. The gas guiding mechanism 7 includes a gas guiding channel 701, a storage platform 702, a first gas guiding port 705, a second gas guiding port 706, and a flow guide 707. The storage platform 702 is disposed on the sealing gasket 9, and the storage platform 702 and the inner wall of the sealing gasket 9 form the gas guiding channel 701. The first gas guiding port 705 and the second gas guiding port 706 are symmetrically disposed on the protective support 1, and the flow guide 707 and the filter screen are respectively disposed inside the first gas guiding port 705 and the second gas guiding port 706.
[0022] It should be noted that during the textile operation, the cotton feeding box area of the carding machine needs to sense the cotton feed rate and equipment position in real time to ensure stable machine operation and product accuracy. Therefore, multiple photoelectric sensors 8 need to be installed. This area is a high-frequency area for operators to add material and clean, and their limbs and tools are prone to collisions and snagging with the sensors, causing the photoelectric sensors 8 to bend or even break. Therefore, it is necessary to protect the photoelectric sensors 8. The traditional method is to directly add a cover on top of them. However, this design has two drawbacks. First, when it is necessary to inspect or replace the photoelectric sensors 8, the cover can only be removed directly, making the maintenance work cumbersome. Second, the cover puts the photoelectric sensors 8 in a closed space. Since it is in contact with the carding machine, it will generate some heat. During long-term operation, it will also generate a lot of heat, which will reduce its service life. Therefore, a photoelectric sensor protection device was designed, which can not only solve the protection problem, but also has a heat diversion and cooling function, and facilitates maintenance.
[0023] It should be further explained that the protective support 1 has a sealing gasket 9 inside, and a storage platform 702 is set inside the sealing gasket 9. The photoelectric sensor 8 is set in the groove inside the storage platform 702. Therefore, the entire structure provides a first layer of protection through the protective support 1 and a second layer of protection through the groove of the storage platform 702, preventing damage to the sensor from collision or pulling during the operator's feeding and cleaning process. The protective support 1 has an air guiding mechanism 7 inside, which can guide the hot air inside the protective support 1 through the air guide 707 inside the first air guide port 705, realize air convection and cool the photoelectric sensor 8. The storage platform 702 itself is provided with a first air guiding hole 703, and an air guiding channel 701 is provided around the storage platform 702 to facilitate air convection and improve the cooling effect.
[0024] like Figures 1-4 As shown, the storage platform 702 is provided with a placement slot, and the photoelectric sensor 8 is disposed inside the storage platform 702; the outer wall of the storage platform 702 is provided with a plurality of first air guide holes 703; the sealing gasket 9 is provided with second air guide holes 704 on both sides, and the second air guide holes 704 are correspondingly disposed with the first air guide ports 705; the flow guide 707 is provided with a flow guide fan 708; the interior of the second air guide port 706 is provided with a dehumidification layer.
[0025] It should be noted that the sealing gasket 9 has second air guide holes 704 on both sides, and these second air guide holes 704 correspond to the first air guide port 705, which can realize air convection exchange through the flow guide 707; in order to prevent dust from entering during the airflow exchange process, a filter layer and a dehumidification layer are provided on the second air guide port 706 to prevent dust and moisture from entering.
[0026] like Figures 1-5 As shown, one end of the protective support 1 is provided with a connection hole, and a connector 5 connected to the photoelectric sensor 8 is provided in the connection hole; the sealing cover 3 is fixedly connected to the protective support 1 by screws 10; the bottom of the protective support 1 is provided with a connecting base 2, and a connecting block on the upper part of the connecting base 2 is provided with a through hole 6.
[0027] It should be noted that, for ease of installation, a connecting base 2 is provided on one side of the protective support 1, and the connecting base 2 is provided with a through hole 6 to facilitate connection with cylindrical structures. An L-shaped connecting plate is provided at the bottom of the connecting base 2 to facilitate connection with planar structures.
[0028] It should be further explained that the interior of the sealing cover 3 has a rectangular opening, and an acrylic glass window 4 is movably installed in the through hole of the rectangular opening. It can be flipped open as needed to directly inspect and replace the internal photoelectric sensor 8.
[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
