Description

Technical Field

[0001] This utility model relates to the field of silk-making equipment technology, and more specifically, to a dust-proof spraying device for a feeder photoelectric switch baffle. Background Technology

[0002] A feeder (model such as WPLZA) is installed before the blending and flavoring process on the silk-making line. A pair of through-beam photoelectric switches are installed on both sides of the feeder to control the feeding of the conveyor belt. During production, the feeding conveyor belt starts feeding material. When the material accumulates to a certain height, it blocks the material level photoelectric switch. After a delay, the feeding conveyor belt stops running and stops feeding. Simultaneously, the feeder's bottom belt runs, carrying the material away, the photoelectric switch is no longer blocked, and the feeding conveyor belt starts feeding again. This cycle continues, completing the continuous material transport. The through-beam photoelectric switch consists of a emitter and a receiver, with a detection distance of several meters or even tens of meters. In use, the emitter and receiver are installed on opposite sides of the path of the detected object. When the object passes through, it blocks the light path, and the receiver activates, outputting a switch control signal to control the equipment operation. The through-beam photoelectric switch is characterized by: high sensitivity, high resolution, high brightness, ability to distinguish opaque reflective objects, large effective distance, resistance to interference, low power consumption, fast response time, and long service life.

[0003] The feeder has a hole for the photoelectric switch mounting location, with a transparent acrylic baffle. Because this process involves a lot of dust, dust easily accumulates on the baffle, obstructing the photoelectric switch and causing the feed conveyor to stop. In this case, the material supply may not meet production requirements, impacting normal production. To ensure the photoelectric switch functions properly, the dust accumulated on the baffle must be cleaned promptly to prevent malfunctions.

[0004] Therefore, there is an urgent need for a dust-proof spraying device for the photoelectric switch baffle of a feeder. Utility Model Content

[0025] like Figure 1 As shown, the dust-proof blowing device for the feeder photoelectric switch baffle provided in this embodiment includes: an air pipe 5, which is set near the feeder photoelectric switch baffle. The air pipe 5 is connected to an air source. The air pipe 5 is equipped with a compressed air valve 1, a solenoid valve 3 and several nozzles 4. The compressed air valve 1 is set at the air inlet end of the air pipe 5, and each of the nozzles 4 is set facing the feeder photoelectric switch baffle.

[0026] Each of the nozzles 4 is made of stainless steel tubing. The solenoid valve 3 includes a two-position three-way solenoid valve. The compressed air valve 1 includes a ball valve.

[0027] Furthermore, the air pipe 5 includes a main pipe and two branch pipes. The compressed air valve 1 and the solenoid valve 3 are disposed on the main pipe. There are two nozzles 4, and each branch pipe is provided with one nozzle 4. Each nozzle 4 faces the baffle corresponding to the light emitter and light receiver of the feeder photoelectric switch.

[0028] During operation, the compressed air valve 1 is opened, and the nozzle 4 is controlled by the solenoid valve 3 to spray compressed air onto the surface of the feeder photoelectric switch. The baffle is periodically sprayed to clean the dust, preventing dust accumulation from causing abnormal detection of the photoelectric switch and preventing the feed belt from stopping due to the photoelectric switch being blocked by dust. This effectively avoids malfunctions during equipment operation and ensures normal production.

[0029] Furthermore, a pressure reducing valve 2 is provided between the compressed air valve 1 and the solenoid valve 3, which controls the intake pressure. Since both the compressed air valve 1 and the solenoid valve 3 are located on the main pipe, the pressure reducing valve 2 is also located on the main pipe. The operating pressure of the pressure reducing valve 2 is 0.1 MPa - 0.15 MPa, for example, 0.12 MPa. In one embodiment of this invention, the pressure reducing valve 2 is a manually adjustable valve. It should be noted that this invention does not specifically limit the type and operating pressure of the pressure reducing valve 2.

[0030] Furthermore, the solenoid valve 3 is connected to a controller for controlling its on / off state. Each working cycle of the solenoid valve 3 consists of being energized for 4-6 seconds (e.g., 5 seconds) followed by being de-energized for 9-11 seconds (e.g., 10 seconds). The controller includes a programmable logic controller (PLC). In a specific implementation, the controller can be configured to allow the solenoid valve 3 to be energized at intervals and de-energized after a certain period, thus completing the cyclic blowing action on the baffle. The PLC model can be, for example, an S7-300. It should be noted that this invention does not specifically limit the type or model of the controller. The operating voltage of the solenoid valve 3 is 24V. In a specific implementation, a 220V power supply can be drawn from the power supply of the power source, and after being regulated, a 24V DC power supply can be output to power the solenoid valve 3. Before production starts, open compressed air valve 1. After production starts, the power supply is engaged, and solenoid valve 3 is energized and begins to work. Each working cycle consists of energizing for 5 seconds and then disconnecting for 10 seconds, and the cycle continues until production ends. Compressed air is sprayed onto the clean area through nozzle 4 at regular intervals to ensure cleaning effect.

[0031] Furthermore, the length of each nozzle 4 is 18cm-22cm, for example, 20cm. Specifically, the end of each nozzle 4 away from the air pipe 5 is sealed, and the end near the air pipe 5 is equipped with a quick-connect plug, which connects to the air pipe 5. Each nozzle 4 has multiple blowing holes. In one embodiment of this utility model, a blowing hole is formed on each nozzle 4 at a preset interval (0.8cm-1.2cm, for example, 1cm). It should be noted that this utility model does not specifically limit the material, size, number of blowing holes, hole diameter, and distribution of the nozzles 4.

[0032] The dust-proof blowing device for the feeder photoelectric switch baffle provided in this embodiment uses a solenoid valve to control the nozzle to blow compressed air onto the surface of the feeder photoelectric switch. The device blows the baffle periodically to clean the dust, preventing the photoelectric switch from being blocked by dust and causing the feed conveyor to stop running. This effectively avoids malfunctions during equipment operation and ensures normal production.
