Description

Technical Field

[0001] The utility model relates to a dispensing head cleaning device, belonging to the technical field of dispensing head cleaning equipment. Background Art

[0002] Glue dispensing operations are involved in the industrial production process. The glue dispensing machine uses a glue dispensing head to dispense glue. The glue has a certain viscosity. When operating for a long time or reoperating after shutdown, the glue dispensing head needs to be cleaned.

[0003] The cleaning of dispensing heads is generally divided into air blowing, ultrasonic, vibration and other methods. Ultrasonic waves and vibrations may cause damage to the dispensing heads. When liquid media is used for cleaning, it is also necessary to frequently replace the cleaning liquid. The air blowing cleaning equipment uses a jet operation method of a jet nozzle, which requires the arrangement of multiple jet nozzles for coverage. In addition, during the air blowing cleaning process, a large amount of glue liquid splashes, causing pollution to the working environment.

[0004] The traditional solution to the splashing problem is to use sealing tubes and other methods. Sealing tubes can improve the splashing situation, but the base inside the tube will still be contaminated by splashing glue. At the same time, the splashed glue in the tube will accumulate between the equipment base and the sealing tube, which is not conducive to the discharge of waste glue and also makes it impossible to recover waste glue. Utility Model Content

[0009] The cleaning cavity is connected with the hollow chamber, the jet ring is provided with a plurality of jet through holes, any of the jet through holes connects the cleaning cavity with the annular air cavity, and the ring carrier is provided with an air supply source connected with the annular air cavity.

[0010] Preferably, a supporting flange located at the bottom of the ring sleeve carrier is provided in the hollow chamber, a sealing ring is provided in the inner cavity of the supporting flange, and the jet ring sleeve is provided with an extension end extending through the sealing ring into the hollow chamber.
