Glue feed mechanism on cigarette making machine

Abstract

The invention discloses a glue feed mechanism on a cigarette making machine, which comprises upper and lower rubber rolls, a glue cylinder and an air cylinder, wherein the upper rubber roll is arranged on a box body and is directly driven by a spindle; the lower rubber roll is supported on the glue cylinder through sealing bearings at two ends of the spindle; the upper part of the glue cylinder isprovided with a glue surface detecting photoelectric tube; rear parts of the upper and lower rubber rolls are respectively connected with a pair of gears in meshed transmission; the lower rubber rollis connected with the gears through a slider coupling; the spindle on a bent arm of the box body is provided with an adjusting handle; the air cylinder is arranged on the lateral surface of the box body and a rack on the air cylinder drives the gears to transmit; a lower part of the periphery of the lower rubber roll is buried in the glue cylinder; and the glue cylinder is supported by a lower bracket. The glue feed mechanism has the advantages of reducing labor intensity of personnel for a machine set and improving the quality of products.

Description

Technical field: [0001] The invention relates to a glue supply device on a cigarette machine, which is particularly suitable for use on the glue supply mechanism of high-speed splicing machines such as PASSIM 12K in the tobacco industry. Background technique: [0002] The glue supply mechanism on the existing Passim and Super Nine units adopts a latex pump (gear pump) to supply glue continuously, and the two rubber rollers are suspended and supported by a triangle bracket, and are pressed against each other by disc springs. Latex is directly injected into the upper part of the joint surface of the two rubber rollers. In order to ensure a complete glue line after the opposite roll, the system always keeps the glue supply of the glue pump greater than the glue application amount of the tipping paper, so the excess latex passes through both ends of the upper and lower rubber rollers. It flows into the lower tray, and flows back into the glue tank through the hose at the lower e...

Problems solved by technology

In addition, during the use of the mechanism, the use of glue recycling is its biggest drawback; in order to ensure the flexible operation of the glue supply mechanism, a certain amount of grease must be used, so when the equipment is running, part of the grease will inevitably The reflowed latex belt enters the rubber tank, causing latex pollution. After the machine runs at high speed for a certain period of time, the surface temperature of the rubber roller is high due to the high-speed pure rolling of the upper and lower rubber rollers. After the reflowed latex belt takes part of the heat, When the temperature rises, air bubbles are likely to be generated after entering the glue tank, and the water content and viscosity of the latex are both reduced. The existence of these defects directly causes quality defects such as flash, air leakage, wrinkles, and full glue.
