This application belongs to the field of cigarette manufacturing technology, specifically relating to a glue application device for bonding filter tip forming paper, including a mounting bracket mechanism, a hot melt glue gun, and a forming paper glue application mechanism; the mounting bracket mechanism is used to fix the glue application device; the hot melt glue gun is set at the top of the mounting bracket mechanism and is used to apply hot melt glue for bonding the forming paper. One end of the glue nozzle has two sets of glue outlet holes, which are used to apply glue lines for bonding the overlapping joints of the forming paper and for bonding the forming paper to the filter element, respectively. Controlled by the opening and closing of a solenoid valve, the glue liquid is squeezed out from the glue outlet holes on both sides of the glue nozzle to form two sets of glue lines, while the hot melt glue gun independently applies a third set of glue lines, realizing triple bonding function. The structure is simplified, the cost is reduced, it is suitable for large-scale industrial applications, supports hot melt glue of various viscosities, is flexible in operation, does not require frequent shutdowns for cleaning, has stronger adaptability, the solenoid valve is a standard part with a long service life, the glue nozzle fixing design reduces wear, the equipment operates stably, and requires virtually no maintenance.

A rotary electronic component (80) applies a moderate elastic force to the sliding portion (50a) towards the annular electrode (32) and holds the sliding portion (50a) in place by providing a buffer member (82) between the sliding portion (50a) of the slider (50) and the rotor (40). This suppresses vibration of the sliding portion (50a) and reduces metal fatigue of the slider (50). Furthermore, by impregnating the buffer member (82) with lubricant and bringing a portion of the buffer member (82) into contact with the annular electrode (32), lubricant can be applied to the annular electrode (32). This smooths the sliding of the sliding portion (50a) and further reduces wear on the contact area. Additionally, the buffer member (82) functions by wiping the surface of the annular electrode (32), thus collecting dust and other foreign matter on the annular electrode (32) and preventing adverse effects of foreign matter on the contact area. Therefore, this rotary electronic component (80) achieves a long service life and high operational reliability.

The utility model discloses a pipeline joint maintenance heat preservation and corrosion prevention system which comprises a constant potential rectifier, a power supply pile, a carbon fiber auxiliary anode, a control switch, a voltmeter, an annular carbon fiber infrared heating plate and a pipeline bracket.
